DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a card sending apparatus suitable for use in a card issuing machine for issuing a plurality of cards stored in a cassette one by one from a card ejection slot.

[0002]

2. Description of the Related Art Generally, in a card issuing machine of this type, a card is issued when a part of the card is exposed from the card exit so that the card to be issued does not fall from the card exit of the card issuing machine. The operation is stopped, and after that, the exposed portion of the card is grasped by hand and pulled out from the card issuing machine. In this case, the card is held between the rollers of the card sending device in the ticketing machine,
A load is applied when extracting by hand, making it difficult to extract. Therefore, in order to solve this problem, a one-way clutch is provided between the roller and the rotating shaft to make it easy to remove the card.

[0003]

However, in the above-mentioned conventional card sending device, there is a problem that the manufacturing cost is increased because the one-way clutch is used. Also, by using a one-way clutch, when a card jam occurs in the card transport path of the card sending device, the jammed card cannot be transported in the reverse direction. A so-called retry operation for removing a card jam by carrying the sheet to the printer cannot be performed. For this reason, once the card jam occurs, the card issuing operation must be stopped, the door of the card issuing machine must be opened, and the jammed card must be removed.

[0004] The present invention has been made in view of the above-mentioned conventional problems, and a first object is to reduce manufacturing costs. A second object is to improve usability.

[0005]

In order to achieve the above object, according to the first aspect of the present invention, there is provided a rotating body which is rotationally transmitted from a driving source, and a card sending-out mechanism mounted on a rotating shaft of the rotating body. In a card feeding device comprising a roller and a pressing means for pressing a card to the card feeding roller, the card feeding device engages with play between the rotating shaft and the rotating body in the rotating direction of the rotating body. An engagement means was provided. Therefore,
When removing the card by hand, the load is not placed on the hand for the play. When the rotating body is rotated in the opposite direction when the card is jammed, the card delivery roller also rotates in the opposite direction via the engaging means.

According to a second aspect of the present invention, in the first aspect of the present invention, the rotary body is provided with a cylindrical portion, and the engaging means is formed on an inner peripheral surface of the cylindrical portion. And a pin provided on the rotating shaft and orthogonal to the rotating shaft and engaged with the engaging projection of the cylindrical portion. Therefore, play is formed between the pin and the engagement projection.

According to a third aspect of the present invention, in the first or second aspect of the present invention, the card moved by the drive source is stopped on the card sending roller, and the card sending roller of the stopped card is stopped. The length from the contact portion to the rear end of the card is set to be substantially the same as the circumference corresponding to the play of the engaging means. Therefore, when the card is pulled out by grasping it by hand, the rear end of the card is positioned at a position where the rear end of the card is released from being pinched by the delivery roller.

In FIG. 9A, since the card 8 is pressed against the delivery roller 18 by the pressing plate 62, the lowermost card 8A
Moves in the direction of arrow A in the figure. At this time, as described above, since the close contact between the cards is reduced by the inclined portion 60, a slip occurs between the lowermost card 8A and the second card, and the lowermost card 8A Card 8A
Is moved, the load on the delivery roller 18 is reduced.

As shown in FIG. 2B, when the upper card 8 also moves following the lowermost card 8A, the card 8
Is stopped by the thickness gauge 55 and stops moving. At this time, since L1−L <l, the card 8 has not fallen from the step portion 59 to the rib 58. When the delivery roller 18 rotates clockwise, only the lowest card 8A is moved by the thickness gauge 55 as shown in FIG. 9C, and the front end is exposed from the card discharge port 54. In this state, as shown in FIG. 7, only the lowermost card 8A falls from the step 59 onto the rib 58, and the height H of the step 59
Is formed larger than the thickness of one card 8, so that a gap is formed between the lowermost card 8 A and the second card 8. Therefore, there is no vacuum between the bottom card 8A and the second card 8 or a close contact state due to static electricity. In addition, since the surface contact with the second card is reduced, scratches due to friction can be prevented. In addition, since the operation such as air blowing becomes unnecessary, the operability is improved and the manufacturing cost can be reduced.

When the front end of the card discharged from the card discharge port 54 is detected by the card detection sensors 7a and 7b, as shown in FIGS.
Stops, and the movement of the card stops. At this time,
As shown in FIG. 2, since the front end of the card 8 is exposed from the card outlet 6 of the front member 3 of the card issuing machine 1, the exposed front end is grasped by hand and pulled in the direction of arrow A. . As described above with reference to FIG. 6B, the pin 44 is disengaged from the engagement protrusion 43a, and
Since 1 can freely rotate by the play between the engagement protrusions 43a, 43a, the delivery roller 18 can also freely rotate, and the card 8 can be moved without applying a load to the hand. As shown in FIG. 2C, when the pin 44 engages with the projections 43a and 43a again, the rear end of the card 8 is positioned at a position where it does not come into contact with the delivery roller 18, so that the card 8 in FIG. Withdrawal from the outlet 6 becomes possible.

If the card is jammed in the card sending unit 10 before the front end of the card 8 is exposed from the card outlet 6, the motor 18 is once driven in the reverse direction. In this case, the delivery roller 18 and the motor 18
Are connected by the engagement of the pin 44 and the engaging projection 43a, so that the driving of the motor 18 in the reverse direction is transmitted to the delivery roller 18 in the same manner as the driving of the motor 18 in the forward direction. At 6, the delivery roller 18 rotates counterclockwise. By repeating the drive in the reverse direction and the drive in the forward direction of the motor 18, the card 8 is moved in the direction opposite to the direction of arrow A, and the front end of the card 8 in which the card is clogged is forcibly removed. A so-called retry operation, which is exposed from the server, becomes possible. Therefore, even if a card jam occurs, it is possible to reduce the possibility that the card issuing machine 1 becomes unusable due to the work of removing the jammed card, thereby improving the usability.
