Small pressing plate urging means 25 for pressing the card of the card.

  Next, the operation of the card supply device 200 will be described.

  As shown in FIGS. 1 and 2, the card stacking unit 2 composed of a plurality of cards 1 is sandwiched between the push plate 10 and the pickup roller 30 on the rail 45, while supporting the side of the card with the guide 40. is there. The pushing plate 10 presses the last card of the card stacking unit 2 by the biasing means 15 installed between the wall 16 and the pushing plate 10. The card stacking unit 2 presses the frontmost card 1 against the pickup roller 30 while the cards are in close contact with each other by the biasing force of the biasing means 15.

  The card at the forefront of the card stacking unit 2 is discharged to the card discharge port 60 by the rotation of the pickup roller 30 while receiving the pressure inside the card stacking unit 2.

  Below the card stacking portion 2, a lift plate 50 having a triangular wave-shaped groove portion 100 on the upper surface along a direction perpendicular to the card alignment direction is along the card alignment direction. A lift plate base material 55 is joined to the lower portion of the center portion of the lift plate 50, and a cam follower portion 77 is joined to the lower portion of the lift plate base material 55.

  A linear motion cam 70 is in contact with the lower part of the cam follower, and the linear motion cam 70 is connected to a drive shaft 85 that is fed out from an actuator 80. The height of the upper surface of the linear motion cam 70 changes depending on the horizontal position of the linear motion cam 70, and the roller of the cam follower portion 77 in contact with the linear motion cam 70 moves the upper surface of the linear motion cam 70. The lift plate base material 55 to which the cam follower portion 77 is joined and the lift plate 50 joined thereto also change the height.

  Further, the linear motion cam 70 has a bank in the front end direction of the card stacking unit 2, and the linear motion cam 70 is moved in the direction of the rear end of the card stacking unit 2 so that the roller of the cam follower unit 77 comes into contact with the bank. When the linear cam 70 is further moved toward the rear end of the card stacking unit 2, the cam follower 77, the lift plate base 55, and the lift plate 50 move toward the rear end of the card stacking unit 2 (horizontal movement).

  The linear motion cam 70 is assembled on the cam base material 75 (not shown) so that the movable range is limited to the card alignment direction on the cam base material 75.

  The lift plate 50 is joined to the lift plate base material 55, and the lift plate base material 55 is coupled to the lift plate base material support 57 via the slide mechanism 56, and the lift plate base material support 57 is connected to the slide mechanism. It is coupled to the slide mechanism base 59 via 58.

  When the lift plate 50 moves up and down or left and right by the movement of the linear motion cam 70, the lift plate base material 55 is vertical so that the longitudinal direction of the lift plate 50 remains in the card alignment direction. The lift plate base material support 57 to which the lift plate base material 55 is coupled via the slide mechanism 56 is slid in the card alignment direction by the slide mechanism 58. To implement.

  As shown in FIG. 3, the cam base 75 passes through the lift plate base support 57. The horizontal movement of the linear cam 70 is supported by an immovable cam base material 75, and the vertical movement and horizontal movement of the lift plate 50 due to the movement of the linear cam 70 are different from the immovable cam base material 75. Regardless, the lift plate base 55, the cam follower 77, the slide mechanism 56, the lift plate base support 57, the slide mechanism 58, and the slide mechanism base 59 can be used.

  The drive shaft 85 in the card alignment direction connected to the linear motion cam 70 is driven by the actuator 80 to drive the linear motion cam 70.

By driving the linear cam 70, the cam follower portion 77 that comes into contact with the linear cam 70 from above, the lift plate base material 55 to which the cam follower portion 77 is coupled, and the lift plate 50 to which the lift plate base material 55 is coupled are moved up and down. Perform horizontal movement. By driving the linear cam 70, the following three positions of the lift plate base material 55 are realized as shown in FIG.

  (First position) A first position where the lift plate 50 is not in contact with the push plate 10 (FIG. 6A).

  (Second position) A second position where the groove portion 90 on the lower surface of the push plate 10 and the groove portion 100 on the upper surface of the lift plate 50 are fitted at a position higher than the height position of the lift plate 50 at the first position (FIG. 6 (b)).

  A triangular wave-shaped groove portion 100 is provided on the upper surface of the lift plate 50, and a triangular wave-shaped groove portion 90 is provided on the lower surface of the push plate 10 along the direction perpendicular to the card alignment direction. As the lift plate 50 is raised, the groove portion 90 on the lower surface of the push plate 10 and the groove portion 100 on the upper surface of the lift plate 50 are fitted.

  (Third position) A third position where the second position of the lift plate 50 remains at the second position and moves slightly horizontally toward the push plate urging means 15 (FIG. 6C).

  When the linear cam 70 is further driven from the state of the second position in the direction of the rear end of the card stacking unit 2 by the drive shaft 85, the roller of the cam follower 77 comes into contact with the bank of the linear cam 70, and the cam follower The portion 77, the lift plate base 55 and the lift plate 50 coupled thereto are moved toward the rear end of the card stacking portion while the groove portion 90 on the lower surface of the push plate 10 and the groove portion 100 on the upper surface of the lift plate 50 are fitted. Realize the third position.

  By driving the linear cam 70, the lift plate 50 is changed from the first position to the second position and from the second position to the third position. When the groove portion 90 on the lower surface of the push plate 10 and the groove portion 100 on the upper surface of the lift plate 50 are fitted in the second position and further changed from the second position to the third position, the groove portion on the lower surface of the push plate 10. 90 and the groove 100 on the upper surface of the lift plate 50 are fitted, the lift plate 50 moves in the direction of the biasing means 15, and accordingly, the push plate 10 also moves in the direction of the biasing means 15. In the first and second positions of the lift plate 50, the push plate 10 presses the card stacking unit 2 by the biasing means 15 in the front end direction of the card stacking unit 2 (in the direction of the pickup roller 30). By changing the position of the second plate 50 from the second position to the third position, the push plate 10 moves in the direction of the biasing means 15 opposite to the front end direction of the card stack portion 2 (in the direction of the pickup roller 30). 2 is reduced in the pressing force toward the front end direction of the card stacking unit 2 (in the direction of the pickup roller 30).

  A small pressing plate 20 that contacts the card of the card stacking unit 2 and a small pressing plate biasing means 25 that presses the card of the card stacking unit are provided in the concave portion at the center of the side surface of the pressing plate 10.

  When the pressing force toward the front end direction (in the direction of the pickup roller 30) of the card stacking portion 2 of the card stacking portion 2 of the push plate 10 is relieved by the change in the position of the lift plate 50 from the second to the third, the small push plate is attached. The pressing force of the card in the card stacking portion 2 of the small pressing plate 20 by the biasing means 25 becomes dominant. Even if the pressing force applied to the card stacking unit 2 by the pressing plate 10 is reduced, the card stacking unit 2 is pressed by the small pressing plate 20 with a force smaller than the pressing force applied to the card stacking unit 2 by the pressing plate 10. Maintain the alignment of

  By changing the position of the first to third lift plates 50 when the card is ejected, the pressing force of the card stacking portion 2 of the pressing plate 10 can be reduced.

  In the supply of a card for picking up the first card from the stacked cards, it is possible to reduce the sticking force between the cards in the card stacking unit at the time of card pickup, and to provide a card supply device that does not have a problem of double feeding.
