  The rotation of the performance unit 162 in the directions 165a and 165b is realized, for example, by driving a motor (not shown) disposed below the support table 163 to rotate the support table 163 in the directions 165a and 165b. Similar to the movement of the pickup 166 described above, the rotation direction can be switched by using a bidirectionally rotatable motor as the motor and switching the rotation direction of the motor. The performance unit 162 is also provided so that it can be raised and lowered.

  FIG. 12 is a cross-sectional view showing a simplified configuration of the playback device 193 during playback. First, CDs are held one by one in trays 177 and 178, and such trays 177 and 178 are integrally supported by a support member 179 in a stacked state. In this state, it is stored in the storage unit 161 of the playback device 193.

  The support member 179 includes an upper support member 179a and a lower support member 179b, and trays 177 and 178 are disposed between these members. For example, protrusion-like engaging portions 180, 181; 182, 183; 184 are formed on the same side surface side of the trays 177, 178 and the upper support member 179a when the support member 179 supports the trays 177, 178, respectively. Has been. The engaging portions 180 to 183 of the trays 177 and 178 are provided, for example, so as to be arranged in a straight line on the side surface of the tray 177 disposed above. The intervals between the engaging portions 180 and 181; 182 and 183 provided on the trays 177 and 178 are selected to be the same length. The engaging portion 184 of the upper support member 179a may be provided in a straight line on the side surface of the tray 177 and arranged at a portion other than the engaging portions 180 to 183, or as shown in the figure. The upper support member 179a may be provided so as to be disposed over the entire side surface of the upper support member 179a above the tray 177.

  In the state before storage, the trays 177 and 178 are supported and integrated by the support member 179, and in the state after storage, the playback device 193 is provided with a mechanism in which the trays 177 and 178 are arranged independently. It is done.

  For example, the upper support member 179a is provided with a protruding piece that protrudes toward the lower support member 179b and has an engaging portion at the tip, and the lower support member 179b is fitted with the protruding piece provided on the upper support member 179a. In addition, with the protruding piece of the upper support member 179a fitted into the window of the lower support member 179b, the engaging portion at the tip of the protruding piece of the upper support member 179a and the end of the window of the lower support member 179b A holding mechanism having an engaging portion biased so as to be engaged with the support member 179 is provided. In the state before storage, the upper and lower support members 179a and 179b are integrated by the holding mechanism so as not to be separated. Furthermore, the engaging portion of the holding mechanism is configured to move during storage, and in the state after storage, the engaging portion of the protruding piece of the upper support member 179a and the window of the lower support member 179b are connected to the holding mechanism. It is configured not to engage with the engaging portion. Accordingly, the trays 177 and 178 sandwiched between the upper and lower support members 179a and 179b are stored independently of each other.

  At the time of reproduction, the CD to be reproduced is first designated by the operator. When a CD is designated, a space is formed immediately below the designated CD tray, that is, between the tray and the tray or lower support member 179b disposed below the tray. FIG. 12 shows a case where a CD held on the lower tray 178 is designated. In this case, a space is formed between the tray 178 and the lower support member 179b. This space is formed by the tray selector 194.

  The storage unit 161 and the performance unit 162 are covered with a frame 191, and a window 192 a in which a tray selection unit 194 is disposed is provided on the upper surface 192 of the frame 191. The tray selection unit 194 includes a slide plate 189 parallel to the upper surface 192, and engaging portions 185 to 188 that protrude toward the bottom surface of the frame 191 are formed on one side surface of the slide plate 189. The engaging portions 185 and 186 are engaged with the engaging portion 184 of the upper support member 179a, and the engaging portions 187 and 180 are either one of the trays 177 and 178. 181; 182 and 183 are provided on the slide plate 189 so as to engage with each other. That is, the slide plate 189 is provided so as to be movable in a direction 195 parallel to the arrangement direction of the engaging portions 180 to 183. The slide plate 189 is moved in the direction 195 so that the engaging portions 187 and 188 engage with the engaging portions 180 to 183 provided on the designated CD tray.

  The slide plate 189 is also provided so as to be able to move up and down in a direction 196 orthogonal to the direction 195, and the engaging portions 187 and 188 and the engaging portions 182 and 183 are engaged as described above. Thus, by raising the slide plate 189, a space is formed between the tray 178 and the lower support member 179b. When the CD held on the tray 177 is designated, the slide plate 189 is moved in the direction 195 so that the engagement portions 187 and 188 and the engagement portions 180 and 181 are engaged, and then the slide plate 189 is moved. Is raised in the direction 196, a space can be formed between the tray 177 and the tray 178. Even if any CD is designated, since the engaging portion 184 of the upper support member 179a is engaged with the engaging portions 185 and 186, the upper support member 179a can be reliably moved upward. it can.

  When the space is formed as described above, the gantry 199 to which the rotating shaft 164 of the support base 163 is fixed is moved up and down in accordance with the position of the space, and the performance unit 162 is moved up and down. Further, the support base 163 rotates in the direction 165a about the rotation shaft 164, and the performance section 162 is disposed in the space. At this time, the positioning member 197 provided on the support base 163 is engaged with the positioning member 198 provided on the lower support member 179b of the support member 179, so that the performance section 162 can be reliably arranged in the space. . Since the space formed by selecting the tray is formed at a different height depending on the selected tray, the positioning member 198 formed on the lower support member 179b is provided according to the position of each height. It is done. In such a state, the CD 190 held on the tray 178 is placed on the turntable 167 and rotates as the turntable 167 rotates, and the pickup 166 moves in the direction 175a and is recorded on the CD. Information is read. When the reproduction is completed, the CD 190 is again held on the tray 178, and the support base 163 rotates in the direction 165b.

  As described above, at the time of playback, the performance unit 162 moves in a direction closer to the storage unit 161 and the storage unit 161 and the performance unit 162 are arranged so as to overlap each other. The storage unit 161 and the performance unit 162 are arranged so as not to overlap each other. When the performance unit 162 is configured using the standard pickup 166 and the turntable 167, the length L1 from the threaded portion 168 side end to the engaging portion 173 side end of the pickup 166 is 40 mm to 45 mm. The diameter L2 of the turntable 167 is about 30 mm.

  In the prior art, since the turntable 167 is fixed and the pickup 166 is moved in the directions 175a and 175b, the performance portion 162 is relatively large. For example, even if the pickup 166 itself is improved so that the length L1 is reduced, the minimum number of parts constituting the pickup 166 is determined, and the minimum required size is determined for these parts. Therefore, for example, the length in the height direction becomes large. Due to the large performance section 162, the entire playback device 193 is also enlarged. The playback device 193 is used by being mounted on, for example, an instrument panel portion of a vehicle. Since such a playback device 193 also has a CD storage portion disposed on the instrument panel portion, a smaller playback device 193 is required. ing.

  Further, in the reproducing apparatus 193, the tray selecting unit 194 is disposed in the vicinity of the upper part of the reproducing apparatus 193 so as to move up and down in the direction 196. As the size of the playback device 193, for example, a standard of 1 DIN (width (W) × height (H) × depth (D) = 180 × 50 × 165) is defined, and the playback device 193 is configured to the size. In this case, the number of CDs that can be stored is relatively small due to the tray selection unit 194 provided near the top of the playback device 193.

  Further, in the reproducing apparatus 193, the positioning member 197 of the rotated support base 163 is engaged with the positioning member 198 provided on the lower support member 179b of the support member 179. Although the positioning member 198 is always arranged at the same height, the support base 163 moves up and down with the up-and-down displacement of the mount 199, so that the position in the height direction varies. Therefore, the positioning members 197 and 198 do not engage with each other, and accurate and reliable positioning cannot be performed. For this reason, the CD cannot be reliably reproduced. Also, the up-and-down displacement of the performance unit 162 and the up-and-down displacement for selecting a tray to form a space are realized by different mechanisms, and after the positioning members 197 and 198 are engaged, the gantry 199 is moved up and down. I can't do it. Therefore, for example, the lifting mechanism of the gantry 199 cannot be used for the operation of selecting a tray to form a space.

The holding members 116 to 118 are stacked and placed on the support member 119. The carrier portions 139, 135, and 137 are stacked so as to be aligned so that the carrier portions 140, 136, and 138 are parallel to each other.

  The stacked holding members 116 to 118 and the support member 119 are supported by the support member 120. The support member 120 has a side surface 121 disposed on the convex portions 128 to 131 side and a side surface 122 disposed on the convex portions 132 and 133 side. Long holes 123 and 124 are formed in the side surface 121, and long holes 125 are formed in the side surface 122. Protrusions 128 and 129 are inserted into the long holes 123, convex parts 130 and 131 are inserted into the long holes 124, and convex parts 132 and 133 are inserted into the long holes 125, respectively.

  In such a storage unit 111, trays 112 to 114 each holding a plurality of (three in this embodiment) CDs 102 are inserted by an operator. For example, the trays 112 to 114 are held in the magazine unit 115 in a stacked state and inserted from the direction indicated by the arrow 127. In order to guide the CD straight, guide grooves 115 a and 115 b are provided on the bottom surface of the magazine portion 115, and guide pieces 119 a and 119 b are provided on the bottom surface 126 of the support member 119.

  At this time, the three trays 112 to 114 are inserted and held in the three holding members 116 to 118, respectively. For example, the magazine part 115 is provided with protruding pieces at equal intervals, and a tray is supported on each protruding piece so that a gap is formed between the trays. By inserting the tray held in the magazine unit 115 in this way, the tray is inserted into the holding members 116 to 118. Further, a lever or the like for releasing the support of the tray by the protruding piece of the magazine portion 115 is provided so that the inserted tray is held only by the holding member.

  When the CD to be reproduced is designated by the operator, the holding member is held immediately below the holding member that holds the designated CD, that is, between the holding member and the holding member or the support member 119 disposed below the holding member. A space is formed. Specifically, the cam members 2 to 4 are moved up and down by the above-described up-and-down displacement mechanism, and the cam members 2 to 4 are moved horizontally by the horizontal movement mechanism. As a result, the holding surfaces 2a to 4a of the cam members 2 to 4 come into contact with the convex portions 128 to 133 of the holding member that holds the designated CD, and the convex portions come into contact with the contact surfaces 2a to 4a. A space is formed between the holding member in which the convex portion is supported by the support surfaces 2b to 4b and the convex portion is in contact with the contact surfaces 2a to 4a and the holding member or the support member 119 below the holding member. Is formed.

  On the placing surface 10 of the gantry 1 is placed a performance unit 104 which is a reproducing means shown in FIG. The performance unit 104 is configured by arranging a pickup 90 and a disc-shaped turntable 91 that can be moved and rotated by a moving means as described later on a support substrate 81.

  The support substrate 81 rotates in the directions 105 a and 105 b around the rotation shaft 82 so as to be movable between a position indicated by a solid line and a position indicated by a two-dot chain line 89. Fixed on top. As a result, the pickup 90 and the turntable 91 provided on the support substrate 81 can be carried into / out of the space formed as described above. Such rotation of the support substrate 81 transmits the power from the motor 88 to the semi-disc gear 83 fixed to the shaft 82 via the worm 87 and the plurality of gears 84 to 86, and the rotation direction of the motor 88. This can be realized by switching.

  In this embodiment, the CD moves so that the pickup 90 fixed on the support substrate 81 follows the radial direction of the CD when the support substrate 81 is disposed at the position of the two-dot chain line 89. That is, the turntable 91 is provided so as to be movable in the directions 106a and 106b. Accordingly, the turntable 91 is provided so as to be movable between a position indicated by a solid line and a position indicated by a two-dot chain line 101.

  Specifically, a feed screw 93, which is a bar-like member that is disposed on the support substrate 81 in parallel with the directions 106a and 106b and is threaded on its outer surface, is fixed. A screwing portion 92 having an insertion hole with a threaded inner surface is fixed to the turntable 91, and the screwing portion 92 is screwed with the feed screw 93.

  Further, the turntable 91 is provided with an engaging portion 99, and the engaging portion 99 engages with the guide portion 100 provided on the support substrate 81. A gear 94 is fixed to one end of the feed screw 93, and power from the motor 98 is transmitted to the gear 94 via a gear 97, a gear 96 and a worm 95. By driving the motor 98, the feed screw 93 rotates and the turntable 91 moves in the directions 106a and 106b. Since the engaging part 99 is engaged with the guide part 100, the turntable 91 can move reliably in the directions 106a and 106b. The moving means of the turntable 91 includes a feed screw 93 and a guide part 100.

  Further, the turntable 91 is provided so as to be rotatable by a motor 107 disposed on the back side of the support substrate 81. When the performance unit 104 is carried into the space, the CD 102 held by the holding member arranged directly above is placed on the turntable 91. The mounted CD 102 rotates with the rotation of the turntable 91, and moves from the position indicated by the solid line to the position indicated by the two-dot chain line 103 by the movement of the turntable 91. At this time, the recording information is read from the central portion toward the outer peripheral portion of the CD 102 by the pickup 90.

  When the support substrate 81 moves to the position of the two-dot chain line 89, the positioning member 81a of the support substrate 81 is inserted into the insertion hole 73 that is the engagement member of the gantry 1 and is positioned. In this embodiment, the gantry 1 can be raised and lowered even after such positioning is completed.

  In addition, each tray holds a CD so that the CD held by the holding member arranged directly above is placed on the turntable 91 of the performance unit 104 carried into the formed space. In addition, a mechanism for releasing the holding of the CD may be formed. For example, a cam member 201 as shown in FIG. 6 may be used in place of the cam members 2 to 4 described above.

  When the cam member 201 is used in place of the cam member 2 and a space is formed between the holding member 116 and the holding member 117, the cam member 201 is displaced up and down and the protrusion 128 is brought into contact with the cam member 201. The convex portion 128 that is in contact with 201 a and is in contact with the horizontal movement of the cam member 201 is held by the first support surface 203. As a result, a space can be formed between the holding member 116 and the holding member 117. The performance unit 104 is carried into the space formed in such a state. When the carry-in of the performance unit 104 is completed, the cam member 201 is horizontally moved again and the convex portion 128 is held by the second support surface 204. As a result, the holding member 116 is lowered to a position where the CD is placed on the turntable 91, and the CD is mounted on the turntable 91. Further, the cam member 201 is moved horizontally to hold the convex portion 128 on the third support surface 205. As a result, only the CD is arranged on the turntable 91, that is, the holding of the CD by the tray 112 is released, and the CD can be reproduced. In this way, only the CD may be placed on the turntable 91.

  FIG. 7 is a block diagram showing an electrical configuration of the playback device 141. The playback device 141 detects the positions of the first lever 5, the second lever 7, the motors 143, 144, 88, 98, 107 that drive the performance unit 104 and the turntable 91 and the position of the first lever 5.

It is comprised including.

  The position detectors 145 to 147 may be realized by sensors that detect that the first lever 5, the second lever 7, and the performance unit 147 are arranged at predetermined positions, or of the motors 143, 144, 88. You may implement | achieve with the measurement means which counts rotation amount.

  FIG. 8 is a flowchart showing the operation of the control unit 142. FIG. 9 is a side view showing stepwise the displacement of the cam members 2 and 3 driven by the control of the control unit 142. In step a1, the reproduction designation unit 149 designates the reproduction of the CD and the CD to be reproduced by an operation by the operator. In step a2, the control unit 142 turns on the motor 143. As a result, the first lever 5 moves horizontally from the initial position. In step a3, the output from the first lever position detector 145 is read to determine whether or not the first lever 5 is placed at a predetermined position suitable for playing the designated CD. When the first lever 5 is disposed at a predetermined position, the process proceeds to step a4 and the motor 143 is turned off. In this way, the cam members 2 and 3 rise in the direction 155 and are arranged as shown in FIG.

  In step a5, the control unit 142 turns on the motor 144. As a result, the second lever 7 moves horizontally from the initial position. In step a6, the output from the second lever position detector 146 is read to determine whether or not the second lever 7 has been placed at a predetermined position suitable for carrying in the performance unit 104. When it is arranged at a predetermined position, the process moves to step a7 and the motor 144 is turned off. As a result, the cam members 2 and 3 are moved in the direction 157, the convex portions 129 b and 131 b of the holding member 118 are brought into contact with the contact surfaces 2 a and 3 a, and the holding member 118 is further stacked on the holding member 118. The holding members 116 and 117 are lifted, and the convex portions 129b and 131b are supported by the support surfaces 2b and 3b. In this way, a space 159 as shown in FIG. 9B is formed between the holding member 118 and the support member 119.

  In step a8, the motor 88 is turned on. As a result, the performance unit 104 rotates from the initial position and is carried into the space 159. In step a9, the output from the performance unit position detection unit 147 is read to determine whether or not the performance unit 104 has been placed at a predetermined position. When the performance unit 104 is arranged at a predetermined position, the process proceeds to step a10 and the motor 88 is turned off. At this time, in the performance unit 104, the positioning member 81 a of the support substrate 81 is engaged with the insertion hole 73 provided in the side surface 11 of the gantry 1.

  In step a11, the motor 144 is turned on in the opposite direction to step a5. As a result, the holding member 118 is lowered and the CD 102 is placed on the turntable 91. In step a12, it is determined whether or not the second lever 7 is disposed at a position suitable for the CD 102 being disposed on the turntable 91. When the second lever 7 is disposed at a predetermined position, the process proceeds to step a13 and the motor 144 is turned off. .

  In step a14, the motor 144 is turned on in the same direction as step a5. As a result, the holding member 118 is raised, and only the CD 102 is placed on the turntable 91. In step a15, it is determined whether or not the second lever 7 is disposed at a predetermined position suitable for reproducing the CD 102. When it is arranged at a predetermined position, the process proceeds to step a16 and the motor 144 is turned off. As a result, the holding members 116 and 117 that are stacked and disposed above the holding member 118 including the holding member 118 are lifted, and the convex portions 129b and 131b are again supported by the support surfaces 2b and 3b.

  In step a17, the motor 107 and the motor 98 are turned on. As a result, the turntable 91 moves horizontally from the initial position while rotating, and a predetermined CD is reproduced. In step a18, it is determined whether or not the reproduction should be terminated. This is determined based on, for example, an output from the stop designating unit 150 based on an operator's operation. If it is determined that the reproduction should be terminated, the process proceeds to step a19 and the motor 98 is turned off. Further, turning off the motor 107 also stops the rotation of the turntable 91.

  At step a20, the motor 98 is turned on so as to rotate in the direction opposite to that of step a17. In step a21, it is determined whether or not the turntable 91 is disposed at a predetermined position (initial position). If it is determined that the turntable 91 is disposed, the process proceeds to step a22 and the motor 98 is turned off.

  In step a23, the motor 144 is turned on so as to rotate in the direction opposite to that in step a5. In step a24, it is determined whether or not the second lever 7 is disposed at a predetermined position. If it is determined that the motor is disposed, the process proceeds to step a25 and the motor 144 is turned off. As a result, the CD 102 is held by the tray 114 and the holding member 118.

  In step a26, the motor 144 is turned on so as to rotate in the same direction as in step a5. In step a27, it is determined whether the second lever 7 is disposed at a predetermined position. If it is determined that the second lever 7 is disposed, the process proceeds to step a28. Then, the motor 144 is turned off. Thereby, a space for carrying out the performance unit 104 is formed.

  In step a29, the motor 88 is turned on so as to rotate in the direction opposite to that in step a8. In step a30, it is determined whether or not the performance unit 104 is disposed at a predetermined position (initial state position). If it is determined that the motor is disposed, the process proceeds to step a31 and the motor 88 is turned off.

  At step a32, the motor 144 is turned on so as to be in the direction opposite to that of step a5. In step a33, it is determined whether or not the second lever 7 is disposed at a predetermined position (initial position). If it is determined that the motor is disposed, the process proceeds to step a34 and the motor 144 is turned off.

  In step a35, the motor 143 is turned on so as to be in the opposite direction to the step a2. In step a36, it is determined whether or not the first lever 5 is disposed at a predetermined position (initial position). If it is determined that the motor is disposed, the process proceeds to step a37 and the motor 143 is turned off.

  Note that the stacked holding members 116 to 118 are always urged downward by the pressing member 151 having the shaft 152 as a fulcrum, as shown in FIGS. A spring 153 having one end fixed thereto is attached to the other end different from the one end contacting the upper surface of the holding member 116 of the pressing member 151. The other end of the spring 153 is fixed to the upper surface 59 of the frame 9, for example.

  As described above, according to the present embodiment, since the turntable 91 is moved instead of the pickup 90, the performance unit 104 can be reduced in size, and the entire playback device 141 can also be reduced in size. Such downsizing is very preferable when the playback device 141 is mounted on, for example, an instrument panel of a vehicle.

  Since the mechanism for forming the space for carrying in / out the performance unit 104 is performed using the cam members 2 to 4 and the levers 5 to 8 arranged in parallel to the side surfaces 61 and 62 of the frame 9, For example, when the playback device 141 is configured in accordance with the 1DIN standard, a larger number of CDs can be stored than in the conventional technology. Alternatively, the size in the height direction can be reduced by the same number of stored sheets as in the conventional technique.

  Furthermore, since the positioning member 81a of the rotated support substrate 81 is engaged with the insertion hole 73 of the gantry 1 that moves up and down in the same manner as the support substrate 81, the performance unit 104 can always be positioned reliably. it can. In addition, even after the positioning member 81a and the insertion hole 73 are engaged, the frame 1 can be moved up and down, and the design is highly flexible. Therefore, after the tray is selected, the CD is mounted on the turntable. It is also possible to use the raising / lowering of the gantry 1 for the placing operation or the like.

  In this embodiment, the example in which the trays 112 to 114 holding the CD 102 are respectively stored in the holding members 116 to 118 has been described. However, an example in which the CD 102 is directly stored in the holding members 116 to 118 also falls within the scope of the present invention.

  For example, when reproduction of a desired recording medium is designated from the operation panel, the first lever moves horizontally. Since the second convex portion on the side surface of the gantry is inserted into the stepped second elongated hole of the first lever, the gantry rises along the second elongated hole. Moreover, since the 3rd convex part of a cam member is penetrated by the 1st long hole of the side surface of a mount frame, a cam member also raises with a mount frame. Since the 4th convex part of the 1st lever is inserted in a long slot long in the horizontal direction of a frame, the 1st lever moves only in the horizontal direction. The third convex portion of the cam member is inserted into the third elongated hole that is long in the vertical direction of the second lever through the first elongated hole on the side surface of the gantry, and the fifth convex portion of the second lever is the horizontal direction of the frame. In this case, the second lever does not move.

  Subsequently, the second lever moves horizontally. As a result, the cam member moves horizontally. That is, the cam member moves horizontally while maintaining a predetermined height by the first lever. The contact surface of the cam member is brought into contact with the first convex portion of a predetermined holding means for holding the recording medium or tray by the horizontal movement of the cam member. Further, an upward force is applied to the first convex portion of the holding means, and the holding means disposed above and including the predetermined holding means rises along the contact surface of the cam member. In this way, a space is formed immediately below the predetermined holding means. Reproducing means for reproducing information recorded on the recording medium is carried into or out of the space.

  At the end of reproduction, the second lever first moves horizontally in the direction opposite to that during reproduction so that the support of the first convex portion of the holding means by the cam member is released, and includes a predetermined holding means. The holding means disposed above is lowered to eliminate the space formed immediately below the predetermined holding means.

  As described above, since the space immediately below the predetermined holding means is formed by using the lever or the cam member arranged on the side surface of the holding means, when the same number of recording media or trays as the conventional technique are stored, By doing so, the size of the device in the height direction can be reduced. Further, if the size of the apparatus in the height direction is the same, the number of recording media or trays that can be stored can be increased.

  In addition, since the space immediately below the predetermined holding means is formed by using a lever or a cam member arranged on the side surface of the holding means, if the same number of recording media as in the conventional technique are stored, the height can be increased. The size of the directional device can be reduced. Further, if the size of the apparatus in the height direction is the same, the number of recording media that can be stored can be increased.

  (4) An embodiment as a recording medium reproducing device, wherein the reproducing means described above is used as the reproducing means.

  As the reproducing means, the reproducing means described above can be used. Therefore, the size of the device can be further reduced. In addition, the turntable can be reliably moved with the above-described configuration.

  (5) The reproducing means has a positioning member for fixing the position of the reproducing means in the vertical direction, and the reproducing device for the recording medium further rotates the reproducing means while being placed on the gantry, Rotating means for carrying the reproducing means into or out of a predetermined space is included, and an engaging member is formed on a side surface of the gantry to engage the positioning member when the reproducing means is rotated by the rotating means. A form of a recording medium reproducing device characterized by that.

  The reproducing means formed as described above and carried into or out of the space has a positioning member that fixes the vertical position of the reproducing means. The reproduction means is carried into or out of the space by rotation means for rotating the reproduction means while being placed on the gantry. At the time of carrying in, the positioning member of the reproducing means is engaged with the engaging member formed on the side surface of the gantry. Since the engaging member with which the positioning member of the reproducing means engages is formed on the side surface of the gantry, the positioning member and the engaging member are always arranged at the same height. Therefore, the reproducing means at the time of carrying-in is reliably held without any variation in the position in the height direction regardless of the height of the reproducing means.

  In addition, the positioning member of the reproducing means is engaged with the engaging member formed on the side surface of the gantry at the time of carrying in, and the positioning member and the engaging member are always arranged at the same height. Regardless of the height of the reproducing means, the position in the height direction can be reliably held without any variation.

  (6) The recording medium reproducing apparatus further moves the first lever on the other side surface in the opposite direction in conjunction with the horizontal movement of the first lever on one of the two side surfaces of the gantry. And a second relay lever that moves the second lever on the other side surface in the opposite direction in conjunction with the horizontal movement of the second lever on one of the two side surfaces of the gantry. And the contact surface of the cam member on the one side surface side and the contact surface of the cam member on the other side surface side are arranged in opposite directions, and the step-like second length of the first lever on the one side surface side The recording medium reproducing apparatus according to claim 1, wherein the hole and the stepped second elongated hole of the first lever on the other side face are arranged in opposite directions.

  The first lever on one side and the other side is moved in the opposite direction in conjunction with the first lever on one side of either of the two side surfaces of the gantry. Connect via a relay lever. Similarly, the second levers on the one and other side surfaces are moved in the opposite direction in conjunction with the second lever on either one of the two side surfaces of the gantry. The lever is connected via the second relay lever. Further, the contact surface of the cam member on the one side surface and the contact surface of the cam member on the other side surface are arranged in opposite directions, and the step-like second length of the first lever on the one side surface side is arranged. The hole and the stepped second elongated hole of the first lever on the other side face are arranged so as to face in opposite directions.

  Therefore, by driving the first and second levers on either side to move in the horizontal direction, the first and second levers on one and the other side can be moved together. Moreover, since the movement direction of the levers on both side surfaces is opposite to each other and a space can be formed immediately below the predetermined holding means, the stability of the vertical displacement of the gantry is increased.

  Further, by driving the first and second levers on either side to move in the horizontal direction, the first and second levers on one and the other side can be moved together. Further, since the movement directions of the levers on both side surfaces are opposite to each other and a space is formed immediately below the predetermined holding means, the stability of the vertical displacement of the gantry is increased.
