Abstract

(57) [Summary] [Purpose] To prevent the disc tray from being pulled out from the magazine body by pushing it lightly with a small force when the disc tray is pushed into the magazine body, and strongly moored in the pushed-in state. [Structure] A disc tray mooring cam provided on the magazine body is characterized in that the pushing-side slope is loose and the mooring-side slope opposite to the pushing side is formed at a steep angle.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a disc tray magazine of an automatic disc reproducing apparatus in which a disc tray is pulled out by a claw connected to a conveying means into a multi-stage accommodating portion provided in a magazine main body, and the disc tray is storably inserted.

[0002]

[Prior art]

 The applicant of the present application has proposed a mooring cam having a substantially equilateral triangular front face, which is biased toward the inside of the accommodating portion by a ridge so as to be provided deep inside the accommodating portion of the magazine body. (See Jitsukaihei 1-162157)

[0003]

[Problems to be solved by the device]

 The operation of the mooring cam described in the prior art is that when the above-mentioned claw engages with the U-shaped notch of the disc tray and inserts the tray into the accommodating portion, one slope of the cam facing the insertion side of the disc tray is When the mooring cam is pushed in by pushing with the tip tapered surface and when the tip tapered surface has finished riding over the slope, that is, when the disc tray has been inserted by the set amount, the pushed mooring cam is restored and the other of the cams is pushed. The slanted surface of the disc tray pushes the lock edge of the disc tray, so that the claw that is in contact with one side edge of the U-shaped notch of the disc tray is positioned in the middle of the notch so that the disc tray is slightly accommodated. This allows the vertical movement of the magazine body without hindrance, but the problem is that the slope of one of the mooring cams is steep, so that the nails can be lifted when overcoming. And the pushing of the smooth cam takes deal of load is not performed, the other slope in the opposite inclination is Ji raw problems say would draw the disc tray too loose.

In view of the above, the present invention has an object to improve the shape of the mooring cam so that the pushing of the cam can be performed lightly and the locking of the cam can be performed strongly.

[0005]

[Means for Solving the Problems]

 The present invention for achieving the above object is for storing a tray drawer in which a disc tray is accommodated in a multi-stage accommodating portion provided in a magazine body, and a U-shaped notch provided in the disc tray is connected to a tray conveying means. In the disc tray magazine in which the claws of the above are interposed, and the mooring cam which can be engaged and disengaged is provided in the deep portion of the accommodating portion, the disc tray is biased to project inward toward the accommodating portion by the ridge, and the mooring cam is When the insertion of the disc tray into the accommodating portion by the claws is performed, the driven taper for sliding is pushed by sliding the pushing taper provided at the tip of the disc tray, and the pushing taper surface finishes climbing over the driven slope. When the cam pushed in by the overrun returns to the protrusion on the drop-shaped lock edge provided at the overrun end of the taper surface, the notch of the disc tray Pushing the lock edge so that the disk tray is slightly retracted into the accommodating position so that the claw that is not in contact with the side edge is located in the middle of the notch. For retracting a steep angle that is connected to the end of the driven slope. The gist is that it was formed with a slope.

【Example】

 Reference numeral 1 denotes a magazine main body. In the magazine main body 1, storage units 2 are formed in multiple stages in a direction perpendicular to the paper surface of the main body. Each storage unit 2 has a disk tray 4 on which a disc 3 is mounted. A U-shaped notch 6 is provided in the disc tray portion which is inserted freely from the inlet 5 of the main body 2 and is exposed from the inlet 5, and the notch 6 has a pawl connected to a not-shown transport mechanism. 7, a disk tray 4 biased by a spring 8 toward the inside of the accommodating portion and a mooring cam 9 that is engaged and disengaged are provided on the deep side of each accommodating portion 2.

Therefore, the gist of the present invention is such that the mooring cam 9 is tilted by pushing it by sliding the pushing taper surface 10 provided at the tip of the tray when the disc tray 4 is inserted by the pawl 7. And the mooring cam 9 pushed by the sloping lock edge 10a provided at the end of the taper surface 10 over the end of the sloping driven slope 9a and the driven slope 9a. Is configured to have a steep-angled retracting sloped surface 9b that is connected to the end of the driven sloped surface 9a that pushes the lock edge 10a so that the disk tray 4 can be retracted slightly when the disk is returned to the protruding position.

The lock edge 10a is formed substantially parallel to the retracting inclined surface 9b that pushes the edge, and the pushing taper surface 10 is formed substantially parallel to the driven inclined surface 9a pushed by this. Has been done. 11 is a cushion made of rubber or the like, 12 is a mooring release member, and this mooring release member 12 is always urged by a spring 13 in a direction away from the disc tray 4.

[0009]

[Function of the device]

 FIG. 2 shows a state in which the pushing taper surface 10 at the tip of the disc tray 4 has begun to push in the driven inclined surface 9a of the mooring cam 9, and the pushing taper surface 10 has passed over the driven inclined surface 9a and the lock edge 10a has finished. When it coincides with the retracting slope 9b, the already pushed cam 9 projects and the retracting slope 9b pushes the lock edge 10a to the left in the figure, and this push causes the disc tray 4 to already stop at the set position. Irrespective of the claws 7, the claws 7 are naturally drawn into the accommodating portion, so that the claws 7 are naturally positioned in the middle portion of the U-shaped notch 6.

Further, the disk tray 4 is moored so that it cannot be pulled out from the magazine body 1 because the retracting inclined surface 9b is locked to the lock edge 10a. Further, the release of the mooring is performed by laterally moving the disc tray 4 by pressing the releasing member 12 against the spring 13 and pushing it downward.

[0011]

[Effect of the device]

 As described above, the present invention has the following effects. (A) Since the driven slope of the mooring cam pushed by the pushing taper surface provided on the disc tray is formed to have a gentle inclination, the mooring cam can be pushed in easily by a gentle overcoming action, Therefore, the claw for taking in and out the disc tray can be moved with a weak force. (B) Since the retracting slope that is continuous with the driven slope is formed at a steep angle, which is the opposite of the driven slope, after the pushing taper surface in (a) above gets over the driven slope, , It is possible to moor the retracting slope to the lock edge instantly and securely, and to retract the disc tray by suction. (C) At the same time, by locking the steeply inclined retracting slope and the lock edge, the magazine body of the disc tray can be reliably prevented from being pulled out.
