FIG. 2 is a right side view of the action pen 1. 3 is a perspective view of the action pen 1 as viewed from the diagonally upper right side on the front side. FIG. 4 is an exploded perspective view of the drive transmission unit 20 and the character 40.

  In the following description, it is assumed that the up, down, left, and right directions indicated by arrows at the top of FIGS. 1A, 1C, and 4 correspond to the up, down, left, and right directions of the action pen 1. The first leg 41 is described as the left leg, and the second leg 42 is the right leg. Conversely, the first leg is the right leg and the second leg is the left. Of course, it may be a leg.

  The action pen 1 includes a writing portion 10 that is long in the vertical direction along the axis C, a drive transmission portion 20 disposed at a base end portion (upper end portion) of the writing portion 10, and an upper portion of the drive transmission portion 20. And a character 40 arranged in a walking posture.

  As shown in FIG. 1, the writing unit 10 includes a cylindrical pen body 11 that extends vertically, a core 12 that is housed inside the pen body 11 and used for writing, and a user for inserting and removing the core 12. Has a knock part (operation lever) 13 that is operated by a finger, and a rotary centering mechanism 14 that moves the lead 12 in and out in conjunction with the operation of the knock part 13.

  The pen body 11 is formed in a cylindrical shape (cylindrical shape) extending in the vertical direction, and a lower cap 15 is screwed to the lower end (tip). At the center of the lower cap 15, a through hole 15 a is formed in which the lower end side of the core 12 can slide and enter, and the core 12 allows the lower end to enter and exit from the lower end of the through hole 15 a. Further, a convex portion 12 a is formed on the lower end side of the core 12, and the core 12 is urged upward by a compression spring 16 interposed between the convex portion 12 a and the lower cap 15. A rotating body 14 b of a rotary centering mechanism 14 described later is engaged with the upper end of the core 12.

  A substantially cylindrical tubular member 17 is disposed at the upper end (base end) inside the pen body 11 so as to be movable up and down. The cylindrical member 17 is formed in a cylindrical shape with an upper half portion 17a opening upward, and the lower half portion 17b is formed in a cylindrical shape opening downward. An elevating member 23 of the drive transmission unit 20, which will be described later, is fitted to the upper half portion 17a. In the lower half portion 17b of the cylindrical member 17, an elevating body 14a of a rotation centering mechanism 14 described later is inserted from below.

  The knock portion 13 is provided on the side surface on the upper end side of the pen body 11. A long guide groove 11 a in the vertical direction is formed on the side surface on the upper end side of the pen body 11. For example, the knock portion 13 also serves as a clip used when hooked in a user's clothing pocket or the like, and a connecting portion 13a extending rearward from the back side (rear side) of the upper end penetrates the guide groove 11a. The cylindrical member 17 is fixed.

  The knock portion 13 is urged upward by the above-described compression spring 16 via the core 12, the rotating body 14b of the rotating centering mechanism 14, which will be described later, the elevating body 14a, and the cylindrical member 17 in FIG. (C), it is arranged at the home position P1 shown in FIG. Moreover, the knock part 13 descend | falls to the pressing position P2 shown with a dashed-two dotted line in FIG.1 (C) by the pressing operation (knock down) by a user's finger | toe. When the finger is released, the compression spring 16 urges the finger upwards to return (knock up) from the pressed position P2 to the home position P1.

  The rotary centering mechanism 14 includes a lifting body 14a, a rotating body 14b, and a guide groove 14c that is formed on the inner peripheral surface of the pen body 11 and guides the lifting and lowering operation of the lifting body 14a. In the guide groove 14c, deep grooves and shallow grooves are alternately formed along the circumferential direction. The rotary centering mechanism 14 is a well-known mechanism used in general ballpoint pens and the like, and thus detailed description thereof is omitted.

  In the rotation centering mechanism 14, the cylindrical member 17 integrated with the knock part 13 is lowered, the compression spring 16 is shortened, and the elevating body 14 a is lowered as the knock part 13 is pressed by the user's finger. Further, the elevating body 14a is lowered while applying a rotational force to the rotating body 14b, but the rotating body 14b does not rotate while being guided by the guide groove 14c. Then, the rotating body 14b descends along the guide groove 14c and rotates with a clicking sound when it is removed from the lower end of the guide groove 14c, and is urged upward by the compression spring 16 via the core 12 and guided to the guide groove. 14c. Thereby, the core 12 projects the lower end (tip) from the through hole 15 a of the lower cap 15.

  Thereafter, when the user removes his / her finger from the knock portion 13, the lead 12 maintains the protruding state, and the knock portion 13 returns to the home position P1. Similarly, the rotation centering mechanism 14 can retract the core 12 by the rotation of the rotating body 14b described above and entering the deep guide groove 14c by the next pressing operation of the knock portion 13 by the user.

  Note that the writing unit 10 is not limited to the one having the rotary centering mechanism 14 described above, and the cylindrical member 17 is lowered by the pressing operation of the knock unit 13, and the cylindrical unit is returned by the returning operation of the knock unit 13. As long as the member 17 is raised, it is possible to use another configuration. For example, when the knocking portion 13 is pushed down, the knocking portion 13 is stopped at the lowered position, the core 12 is taken out, and then the notch (not shown) is pushed, so that the knocking portion 13 is moved to the home position by the biasing force of the spring. It is also possible to employ a configuration in which the cylindrical member 17 rises at the same time.

  Among these, the trunk | drum 43 is formed by fitting parts 43A and 43B vertically divided into two front and back. A head 44 is integrally formed at the upper end of the body 43. Through holes 43a and 43b are formed in the upper portions on the left end side and the right end side of the body portion 43, and the left arm portion 45 and the right arm portion 46 are swingably engaged with each other. In addition, on the left and right sides of the lower end of the body portion 43, long holes 43c and 43d that are long in the front-rear direction through which the upper end sides of the first leg portions 41 and 42 pass are provided.

  A support member 47 is integrally provided on the body 43. The support member 47 has a columnar portion 47c extending vertically. Small diameter portions 47a and 47a as upper swinging shafts extending in the left and right directions are formed at the lower end of the columnar portion 47c, and large diameter portions 47b and 47b are formed at the left and right ends of the small diameter portions 47a and 47a. An annular portion 47e having a through hole 47d penetrating in the front-rear direction is formed at the upper end of the columnar portion 47c. A fitting convex portion (not shown) of the part 43A is passed through the through hole 47d and then fitted into the fitting concave portion 43e of the part 43B. Accordingly, the support member 47 is supported by the body portion 43.

  The support member 47 supports a first leg part 41 and a second leg part 42 described below through a small diameter part 47a, 47a so as to be swingable.

  The 1st leg part 41 is comprised by parts 41A and 41B vertically divided into two front and back. The first leg portion 41 has a through hole 41a at the center in the front-rear direction at the upper end. The first leg portion 41 is supported so as to be swingable in the front-rear direction by allowing the small-diameter portion 47a of the support member 47 described above to pass through the through hole 41a. A pair of pin receivers 41b and 41b are formed on the left and right sides of the mating surfaces of the parts 41A and 41B, and the pins 48 are supported in the left-right direction. The pin 48 penetrates the long hole 31d of the first conversion member 31 in the left-right direction.

  In the character 40 described above, the position of the support member 47 is not fixed with respect to the pen body 11 of the writing unit 10 or the housing 21 of the drive transmission unit 20. The small diameter portion 47a is supported from below by the two leg portions.

  As shown in FIGS. 1A to 1C, the action pen 1 is urged upward by the compression spring 24 in the state where the knock portion 13 is disposed at the home position P1, The guide hole 23 b is stopped with the lower end thereof being in contact with the lower swing shaft 22.

  At this time, in the first conversion member 31, the convex portion 31 c engaged with the engagement hole 23 c on the front side of the elevating member 23 is located obliquely above the front side of the lower swing shaft 22. Accordingly, the long hole 31 d of the first conversion member 31 is located obliquely upward on the rear side with respect to the lower swing shaft 22. Thereby, the 1st leg part 41 is arrange | positioned at the last end in the rocking | fluctuation range.

  Similarly, at this time, in the second conversion member 32, the convex portion 32 c engaged with the engagement hole 23 d on the rear side of the elevating member 23 is located obliquely above the rear side of the lower swing shaft 22. Accordingly, the long hole 32 d of the second conversion member 32 is positioned obliquely upward on the front side with respect to the lower swing shaft 22. Thereby, the 2nd leg part 42 is arrange | positioned at the foremost end in the rocking | fluctuation range.

  As will be described below, the elevating member 23 is lowered and raised in response to the lowering and raising of the knock portion 13, thereby causing the convex portion 31 c of the first conversion member 31 shown in FIG. The convex portion 32c of the second conversion member 32 swings substantially vertically about the lower swing shaft 22, but as described above, the other lifting member with which the convex portions 31c and 32c are engaged. Since the 23 engagement holes 23c and 23d are long in the front-rear direction, this swinging operation is allowed.

  Further, in the first conversion member 31 and the second conversion member 32, the elongated holes 31 d and 32 d swing substantially in the front-rear direction as the convex portions 31 c and 32 c swing in the vertical direction, and the first leg portion 41. The second leg part 42 is swung substantially in the front-rear direction, and the first leg part 41 and the pins 48 and 49 of the second leg part 42 are engaged with the long holes 31d and 32d formed long in the vertical direction. Therefore, the first leg 41 and the second leg 42 can be swung in the front-rear direction without any trouble.

Next, the operation (action) of the action pen 1 configured as described above will be described.
When the user uses the action pen 1 for writing, the user presses the knock portion 13 disposed at the home position P <b> 1, and then releases the finger from the knock portion 13. By this series of operations, the knock unit 13 is lowered from the home position P1 to the pressed position P2, and then is raised from the pressed position P2 to the home position P1. As the knock part 13 is lowered and raised, the lead 12 protrudes from the tip of the pen body 11, and writing is possible. After the writing, the core 12 is retracted and stored in the pen body 11 by the next lowering / raising of the knock portion 13 by the user.

  In the action part 40, the first leg part 41 swings forward from the rear end to the front end corresponding to the lowering of the knock part 13 from the home position P1 to the pressing position P2, and at the same time the second part The leg 42 swings backward from the foremost end to reach the end.

  That is, as the knock portion 13 descends, the elevating member 23 descends against the urging force of the compression spring 24, whereby the elongated hole 31d of the first conversion member 31 swings forward, and the first leg The part 41 is swung forward. At the same time, the long hole 32d of the second conversion member 32 swings backward, and the second leg portion 41 swings backward.

  Moreover, in the action part 40, the 1st leg part 41 rock | fluctuates back from the foremost end to the back end corresponding to the raise from the pressing position P2 of the above-mentioned knock part 13 to the home position P1, The second leg 42 swings forward from the rear end to reach the front end.

  That is, as the knock portion 13 is raised, the elevating member 23 is raised, whereby the long hole 31d of the first conversion member 31 is swung rearward, and the first leg portion 41 is swung rearward. At the same time, the long hole 32d of the second conversion member 32 swings forward, and the second leg portion 41 swings forward.

  As described above, in the action pen 1, the first leg portion 41 and the second leg portion 42 swing forward and backward in the reverse direction in conjunction with the lowering of the knock portion 13. In conjunction with the rising of the knock portion 13, the first leg portion 41 and the second leg portion 42 swing backward and forward in the opposite directions. In this way, the walking motion of the character 40 can be generated by raising and lowering the knocking portion 13 by the user.

According to the action pen 1 described above, the following effects can be obtained.
(1) Although it is a simple configuration, it is difficult for the user to associate the first and second leg portions 41 and 42 with the walking motion in the front-rear direction, which is difficult to associate with the vertical movement of the knock portion 13. It will be highly interesting and unexpected.
(2) As the elevating member 13 is moved up and down, one of the first leg 41 and the second leg 42 can be swung forward and the other can be swung rearward. It is possible to make the walking motion closer.
(3) The elevating member 23, the first converting member 31, and the second converting member 32, which are mechanisms for converting the lifting and lowering of the knock portion 13 into the swinging of the first leg portion 41 and the second leg portion 42 in the front-rear direction, are housings. Since the user cannot visually recognize it from the outside, the user does not know how the character 40 performs the walking motion. For this reason, interest and unexpectedness increase further.
(4) Ascending / descending of the elevating member 23 accompanying the elevating of the knock part 13 is performed by swinging the first conversion member 31 and the second conversion member 32 having a simple configuration, opposite to the first leg part 41 and the second leg part 42. It can be transmitted as a swing of direction.
(5) Since the first conversion member 31 and the second conversion member 32 have the convex portions 31c and 32c arranged in opposite directions with respect to the lower swing shaft 22, for example, the first conversion member By arranging one member 31 and the second conversion member 32 in the left-right direction reversed (rotated 180 degrees with respect to the axis C), the same member can be used. For this reason, compared with the case where it is another structure, a number of parts can be decreased.
(6) When the knock portion 13 is lowered from the home position P1 to the pressed position P2, the first leg portion 41 swings from the rearmost end to the frontmost end, and the second leg portion 42 swings from the frontmost end to the rearmost end. Further, as the knock portion 13 is moved from the pressed position P2 to the home position P1, the first leg portion 41 swings from the foremost end to the rearmost end, and the second leg portion 42 swings from the rearmost end to the foremost end. . That is, the character 40 advances one step when the user lowers the knock unit 13 and advances the next one step when the knock unit 13 rises. In other words, since the walking motion corresponds to a motion in which the user puts power in and out, the user can feel that he / she is walking the character 40, thus increasing the interest.
(7) The support member 47 is not fixed in the arrangement position, but is supported by the first leg portion 41 and the second leg portion 42 via the small diameter portions 47a and 47a. It is possible to move. For this reason, for example, by setting the lengths of the long holes 31d and 32d in the first conversion member 31 and the second conversion member 32 in the longitudinal direction to be short, the long holes 31d and 32d are supported by swinging in the front-rear direction. When passing below the member 47, the support member 47 can be pushed upward. In this case, it is possible to imitate the vertical movement of the torso when a person actually walks, so that interest can be further enhanced. Furthermore, since the trunk | drum 43 is supported by this support member 47 so that rocking | fluctuation is possible, it is also possible to make the trunk | drum 43 take a forward leaning attitude | position and a back leaning attitude | position.
