DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a medium feeding device for sequentially feeding media from a gate port through a stacker in which a plurality of media are stacked, which is used in various card issuing machines and the like.

[0002]

2. Description of the Related Art In a card issuing machine for issuing various cards such as a magnetic card, a medium feeding device for sequentially feeding cards one by one from a stacker in which a plurality of cards are stacked to a gate port is known. Already known. FIG. 8 is an enlarged side view showing the relationship of the claw means, which is a main part of the conventional card feeding device.

In FIG. 8, a pawl 41 is engaged with a rear edge of a card 42 so that the card 42 is
5 is a claw means provided so as to move from the right side to the left side in the figure in order to send out to the fifth side. The claw 41 is formed with a claw reference surface Qa at an upper portion in the sending-out F direction and a wall surface V that engages with a rear edge of the card 42. Above the claws 41, a box-shaped stacker 44 that stores the stacked cards 42 is arranged. The gate port 4 is located in the card 42 feeding direction.
5 is provided and the roller 4 below the card 42 is provided.
6 and a gate 48 on the upper side.

In such a conventional card feeding device using a claw, the claw 41 is securely engaged with the card 42 so that the caught state of the claw 41 is further ensured. An inclined portion T is provided at a portion where the rear end edge of the 42 contacts. Further, the reference surface Qa of the claw 41 at the card position QQ is adjusted so that the accuracy of the card set surface P-P does not cause a problem in the engagement between the card 42 and the claw 41. Is set at a position higher than the card set surface PP which is a card position in a state where the card is not engaged with the card setting surface PP.

[0005] The operation of the card feeding device set in the above-described relation position is as follows. First, the cards 42 stacked on the stacker 44 are moved from the lowest card 42A to the gate port 45 by the claw 41 moving in the F direction. Then, the card 42B on the card 42A is sequentially sent out by the claw 41.

[0006]

However, in the card feeding device set at the above-mentioned relational position,
When the card 42A is sent out, since the reference surface Qa of the claw projects beyond the card setting surface PP to ensure engagement with the card 42A, as shown in FIG. What is supposed to be sent out by the wall surface V that originally engages with the rear end edge of the card 42A of the claw 41 may be sent out by the inclined portion T at the tip. When the card 42A is sent out by the inclined portion T, the card 42
B is engaged with the wall surface V, so that the lowermost card 42B is sent out by the wall surface V of the claw 41 in a state where the lowermost card 42A is not discharged from the gate port 45, and There was a problem that a malfunction such as a hopping error in which the mouth 45 was blocked by the card 42A to stop the operation occurred and the card could not be sent out reliably.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and even when the reference surface of the claw projects beyond the card setting surface, the card is sent out by the inclined guide portion of the claw. An object of the present invention is to prevent a problem that a hopping error occurs, and to reliably send out a card.

[0008]

In order to achieve the object, according to the present invention, there is provided a stacker in which a plurality of media are stacked, and a rear end edge of the media which is movably arranged to face the stacker. And a claw means having a delivery claw section for delivering the medium from the gate port by engaging with the claw means, wherein the claw means guides the trailing edge of the medium to the delivery claw section. While having a guide surface, a load means for preventing the medium from moving by the inclined guide surface is provided.

The load means is any one of a spring contacting the medium, a spring biased roller, rubber, a sheet, and a friction member.

Further, the magnitude of the load of the load means is as follows:
The size of the medium is set so as to release the engagement between the trailing edge of the medium and the inclined guide surface.

According to the medium feeding device having such a configuration, the problem that hopping error occurs due to feeding by the inclined guide portion of the claw is prevented beforehand.
The card can be sent out reliably.

That is, when the lowest card 2a descends to the upper part of the sending claw 3a, the sending claw 3a advances to the position of FIG. 6B, and the card 2a is engaged with the engaging portion 3e of the sending claw 3a shown in FIG. Abuts the trailing edge. Next, the sending claw 3a moves forward and the card 2a is sent out. At this time, even if the rear edge of the card 2a is pushed out by the inclined guide surface portion 3b shown in FIG.
As shown in FIG.
A force that pushes back in two directions acts to apply a load force P2 greater than the force P1 sent out by the inclined guide portion 3b to the card 2a to be sent out, and to apply a load force P2 that satisfies the relationship of P2> P1. The tip of the claw means 3 is released from being caught by the inclined guide surface portion 3b, the rear edge of the card 2a is lifted up to the horizontal portion 3c, and the engaging portion 3e is engaged.
Can be brought into contact with the rear edge of the card 2a.

Next, another embodiment according to the present invention will be described with reference to FIG. FIG. 7 is an explanatory diagram showing another embodiment of the gate unit. In FIG. 7, a pillar with a roller is provided so as to apply a biasing force by a spring to the gate section 20. Through the card roller 23
Are rotatably provided, and a spring 24 applies a biasing force in the upward direction of the support 21. When the card 2 passes through the gate 8, the card 2 pushes down the support 21 and the card 2
, A gap can be created for the thickness of one card. As a result, the gate driving mechanism can be simplified.

As described above, the invention made by the present invention has been specifically described based on each embodiment. However, the present invention is not limited to the above embodiments, and various modifications may be made without departing from the gist thereof. Needless to say, for example, in the above-described embodiment, the spring means that comes into contact with the card has been described as an example of the load means, but in addition, a roller biased by a spring, rubber, or a sheet or the like may be used.
