BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a card feeding device for sending cards stacked in a storage section.

[0002]

2. Description of the Related Art In a card issuing machine or the like, a roller or the like is driven in accordance with an ejection command, cards stacked and stored in a storage section are sequentially sent out from the lowest card, conveyed to a recording section and issued. ing. In such a card issuing machine and the like, it is desired to reliably send out cards one by one.

[0003]

However, in the above-described card issuing machines, since the cards are stacked in the storage section, the lowest card and the uppermost card are not placed on top of each other due to static electricity between the cards or burrs at the ends of the cards. Cards tend to stick together. Further, in the card issuing machine, since the exit for discharging the card from the storage section is set between the knife section provided on the center line of the roller and the roller, there is a limit in setting the width of the exit. Therefore, when a card is sent out from the exit, the second card on the same card is sent out to the exit before the lowest card,
There is a problem that the card is jammed.

[0004]

Therefore, in the card feeding device for sending out the lowest one of the stacked cards of the present invention, the card is fed between a roller for sending out the card and an inclined knife portion opposed to the roller. As an outlet, the lower end of the inclined knife portion is shifted in the card sending direction from the center of the roller, and the tip located at the center of the roller between the roller and the lower end.
The vertical gap between the end with a less than twice the thickness of the card, and the vertical spacing between the tip tangent line and the inclined knife portion at the apex of the roller than a thickness of the card.

[0005]

In the card exit formed between the roller for feeding out the lowest card and the inclined knife portion whose lower end is displaced from the center of the roller in the card feeding direction, the center of the roller at the roller exit Located at the lower end and roller
Vertical spacing with a less than twice the thickness of the card and, since the vertical <br/> spacing between the tangent line and the tip at the apex of the roller was less thick card, the lowest by a roller When the second card is sent toward the card exit, the second card above the lowest card may move in the same direction, but the movement is prevented by the inclined knife portion.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. A card feeding device denoted by reference numeral 1 in FIG. 1 includes a guide plate 4 that forms a card storage unit 3 on which cards 2 are stacked.
And a slanted knife portion 5, a slot 8 for guiding the card 2 toward the card passage 6 and a gate 8 formed as a card outlet formed between the slanted knife portion 5, and a lowermost card 2A as a gate. 8 mainly includes a pick-up roller 9 for feeding. Examples of the card 2 include a thin magnetic card such as a prepaid card.

The cards 2 are stacked and stored in a card storage unit 3. A weight 10 is placed on the uppermost card 2B that is stacked, and presses the lowermost card 2A toward the pickup roller 9 disposed below the storage section.

The guide plate 4 is formed slightly larger than the card 2 and covers the card 2 from all sides so as to form a gap L between the inner surface of the guide plate 4 and the card 2. I have. The lower portion 4b of the guide plate 4a located in the card sending direction indicated by the arrow A extends in the same sending direction and forms an upper guide of the card path 6.

[0009] A transport roller pair 11 is disposed on the left side of the gate 8. The conveying roller pair 11 includes a driving roller 11a and a driven roller 11b on which one of the belts 12 and 13 contacting each other is hanged, respectively.
3, the card 2 is held and transported.

The pickup roller 9 is driven counterclockwise by a drive motor (not shown) and is supported so as to be swingable in the direction of arrow B about the shaft 7a of the slot roller 7. When a card sending signal is emitted from a sensor or the like (not shown), the pickup roller 9 operates at a contact position with the lowest card 2A indicated by a solid line, and a card sent by a sensor S1 arranged near the conveying roller pair 11. When the leading end of the card 2A is detected, it is selectively positioned by a lifting mechanism (not shown) at a standby position separated from the card 2A indicated by a two-dot chain line.

A drive roller 11a on which a belt 12 is hung
Are rotated in the same direction in synchronization with the pickup roller 9 by a drive connection mechanism (not shown). The slot roller 7 is rotatably supported at an opposing portion located below the inclined knife section 5.

The inclined knife section 5 is provided on the guide plate 4a. The lower end 5a of the inclined knife portion 5 is inclined downward to the left in the card sending direction A below the lower portion 4b, and as shown in FIG.
b is a plane parallel to the card surface. The lowermost end 5b is
The center line O is formed so as to protrude (offset) from the center line O ′ of the slot roller 7 toward the card sending direction A by an interval δ. Here, the interval δ is set slightly longer than the interval L between the card 2 and the guide plate 4.

The introduction side of the gate 8 , that is, the slot row
The vertical interval H between the tip 5c of the lowermost end 5b located on the center line O 'side of the roller 7 and the peripheral surface of the slot roller 7 is denoted by T
Is set to be 1.5 times the card thickness indicated by, and the vertical distance D between the tip 5c and the tangent C to the center line O 'of the slot roller 7 is set to be 1/2 of the card thickness T. Is set.

According to the card feeding device 1 configured as described above, when a card sending signal is issued, the pickup roller 9 is rotated counterclockwise by a drive motor (not shown), and the roller 9 is moved by a lifting mechanism (not shown). It is swung from a standby position indicated by a two-dot chain line in FIG. 1 to an operating position indicated by a solid line. When the pickup roller 9 rotates, the drive roller 11a rotates in the same direction (counterclockwise), so that the belt 13 that is in contact with the belt 12 rotates clockwise.

When the rotating pickup roller 9 rises and comes into contact with the lowest card 2A, its rotation is transmitted to the card 2A, sent out in the direction of arrow A, and guided to the gate 8. With the movement of the card 2A, the second card 2C, which is in close contact with the same card due to static electricity or the like, also moves with the arrow A
May move in the direction.

However, since the distance D between the tangent line C to the center line O 'of the slot roller 7 and the lowermost end 5b of the knife portion constituting the upper part of the gate 8 is set to 1/2 of the card thickness T, The inclined lower end 5a of the portion is positioned below the card 2C, and only the card 2C contacts the inclined lower end 5a to prevent its movement. The rotation (feeding force) of the pickup roller 9 acts only on the card 2A that is in contact with the roller. Therefore,
Only the lowest card 2A will surely enter the gate 8.

Since the distance H between the tip 5b of the knife portion and the slot roller 7 is set to 1.5 times the card thickness T, no excessive load is applied to the card 2A introduced into the gate 8. Can pass through the gate 8 smoothly.

The card 2A passing through the gate 8 is inserted between the belts 12 and 13 through the card path 6, and the leading end 2A1 is detected by the card sensor S1.
When the sensor S1 detects the leading edge of the card, the pickup roller 9 moves from the solid line position to the position indicated by the two-dot chain line, and the rotation (feeding force) of the pickup roller 9 to the card 2A is interrupted. It is conveyed while being pinched.

By offsetting the center O of the lowermost end 5b of the inclined knife portion 5 with respect to the center line 0 'of the slot roller 7, the position of the gate 8 is shifted in the card sending direction A.

Therefore, the width setting of the gate 8 formed between the lowermost end 5b and the slot roller 7 and the lowermost card 2
The contact pressure between A and the slot roller 7 can be set individually. In other words, by separating the position of the lowermost end 5b from the center of the roller 7, the distance H between the lowermost end 5b and the peripheral surface of the roller 7 can be increased, so that the position of the lowermost end 5b can be lowered and the second card 2C can be reliably brought into contact with the inclined lower end 5a, and its movement can be prevented.

In this embodiment, the tip 5b of the knife portion is used.
The distance H between the roller 7 and the roller 7 is set to 1.5 times the card thickness T, and the distance D between the tangent line C and the lowermost end 5b is set to 1/2 of the card thickness T. In other words, at least the interval H may be set to be twice or less the card thickness T, and the interval D may be set to be equal to or less than the card thickness T. Also, the interval δ
Is set slightly longer than the distance L between the card 2 and the guide plate 4, but setting it to about 2 to 3 mm is also effective.

[0022]

As described above, according to the present invention, the position of the inclined knife forming the card outlet can be lowered.
There is more freedom in setting the width of the exit, the movement of the second card on the lowest card can be blocked by the inclined knife section, and only the lowest card can be securely removed from the storage section. Can be sent.
