Abstract

PROBLEM TO BE SOLVED: To realize a small-sized, lightweight forcible discharging mechanism that requires neither a battery nor a capacitor without clamp resetting operation, etc., for forcible discharging. SOLUTION: When a card 10 is taken in, an energy is accumulated in a spiral spring 8. The spiral spring 8 is prevented by a torque limiter 9 from being wound too much. When the card 10 is processed, the release of the spiral spring 8 is suppressed with the holding torque of a conveyor motor to stop the card 10. When the card 10 is discharged, the spiral spring 8 is released. When the card 10 is issued, the spiral spring 8 is in its initial state, but a one- way clutch 6 idles, so the spiral spring 8 is never wound reversely. If the card 10 stays in the device owing to a power failure after the card 10 is sucked in, the holding torque of the conveyor motor is ceased and the spiral spring 8 where the energy is accumulated is released to eject the card 10.

[0006] When the card 64 is sucked, it is conveyed into the card processing device by the feed shaft 62 and the driven roller 63. At this time, the card 66 is conveyed while pushing the member 66 urged by the spring 65 in the discharge direction. When the sheet is conveyed to the fixed position, predetermined processing such as reading and writing is performed. At this time, the card 64 is biased by a spring in the discharging direction, but is stopped by the pressing force of the driven roller 63.

[0007] When the power supply mechanism is disabled, such as during a power outage, the ejection button 67 is pressed to release the pressing action of the driven roller 63 and the card 64 is ejected by the restoring force of the spring 65.

There is also an example as shown in Japanese Utility Model Laid-Open Publication No. 06-075551. This example will be described with reference to FIG.

This card processing device includes a feed shaft 72 for conveying a card 71 and a driven roller 73, and further includes a solenoid 74, a discharge spring 75, a capacitor 76, and a relay switch 77 for forced discharge.

[0023]

Next, a first embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a plan view of a first embodiment of the present invention, FIG. 2 is a cross-sectional view of FIG. 1 taken along the line ZZ, and FIG. 3 is a view of the first embodiment of the present invention. It is a side view.

The transport system drive unit 1 is composed of a transport motor, a timing belt, etc.
b and 2c are driven. Card 10 is driven rollers 3a, 3
b, 3c and rollers on the feed shafts 2a, 2b, 2c. Feed shaft 2a is gear 4
Is provided. A spiral spring 8 on a spiral spring shaft 7;
The vehicle includes a torque limiter 9 and a gear 5 with a built-in one-way clutch 6. The spiral spring shaft 7 is driven to rotate by the connection between the gear 4 and the gear 5.

Next, the operation will be described.

When the card 10 is sucked into the card processing device, the feed shaft 2a, 2
b and 2c are CW (clockwise) rotations, and convey the card 10 in the α direction. The connection between the gear 4 and the gear 5 causes the spiral spring shaft 7 to rotate CCW (counterclockwise) to store energy in the spiral spring 8. The gear 5 incorporates a one-way clutch 6 and is arranged so as to lock the spiral spring shaft 7 by CCW rotation. At this time, the spiral spring 8 is wound via the torque limiter 9. When sufficient energy for ejecting the card 10 is stored in the spiral spring 8 through the torque limiter 9, a slip is generated and the drive is not transmitted to the spiral spring 8, and the spiral spring 8 is wound. It will not be damaged by passing. When the card 10 is transported to a predetermined position, the card 10 is stopped and predetermined reading and writing are performed on the magnetic stripe of the card 10. Here, to keep the card 10 stopped, the opening of the spiral spring 8 is suppressed by using the holding torque of the transport motor. When the reading / writing to the magnetic stripe is completed, the feed system 2 rotates the feed shafts 2a, 2b, 2c by CCW to convey and eject the card 10 in the β direction. While being conveyed, the spiral spring 8 is opened.

When the card 10 is issued, the feed system 2 rotates the feed shafts 2a, 2b, and 2c in the CCW direction to convey the card 10 in the β direction. At the time of issuance, the spiral spring 8 is in an initial state. When the gears 4 and 5 are connected, the gear 5 built in the one-way clutch 6 idles in the CW direction, so that no drive is transmitted to the spiral spring shaft 7.
Therefore, the spiral spring 8 is not reversely wound.

When an abnormality such as a power failure or motor failure occurs after the card 10 is inhaled and the card 10 remains in the apparatus,
The holding torque of the transport motor disappears, the spiral spring 8 storing the energy is released, the spiral spring shaft 7 rotates CW, and the gear 5 is locked by the one-way clutch 6, so that the feed shaft 2 is rotated CCW and the card 10 is rotated by β. Discharge in the direction.

Further, even if an abnormality such as a power failure or a motor failure occurs when the card 10 is issued, no energy is stored in the spiral spring 8, so that the card 10 is not issued unprocessed.

Next, a second embodiment of the present invention will be described with reference to the drawings.

FIG. 4 is a plan view of a second embodiment of the present invention, and FIGS. 5A and 5B are side views of the second embodiment of the present invention. FIG. 5A is an overall view showing a state when power is supplied, and FIG. 5B is a partial view showing a state when power is not supplied.

The second embodiment is an effective embodiment when the holding torque of the transport motor for stopping the card 10 is severe due to the problem of torque or power consumption. A ratchet wheel 11 is added to the spiral spring shaft 7 described in the first embodiment, and a pawl 12, a solenoid 13, a return spring 14, and a rod 15 are provided on the ratchet wheel 11.

Next, the operation will be described.

When the card 10 is sucked into the card processing device, the solenoid 13 is energized to suck the rod 15 so that the claw 12 is engaged with the ratchet wheel 11.
As described in the first embodiment, the spiral spring 8 is wound by the rotation of the feed shaft 2 due to the suction of the card 10. At this time, the ratchet wheel 11 can rotate while pushing the claw 12. After transporting to the predetermined position, Card 1
0 is stopped and predetermined reading / writing is performed on the magnetic stripe of the card 10. The reason why the card 10 is stopped here is that the pawl 12 prevents the ratchet wheel 11 from rotating CW. Card 10
When the reading / writing to the magnetic stripe is completed, the feed shafts 2a, 2b, 2
The card 10 is rotated CCW to convey and eject the card 10 in the β direction. At this time, the connection of the gears 4 and 5 causes the gear 5 built in the one-way clutch 6 to idle in the CW direction, so that no drive is transmitted to the spiral spring shaft 7. Therefore, the spiral spring 8 keeps storing energy. Even if the card 10 is discharged and the card 10 is sucked again, the spiral spring 8 is not affected by the torque limiter 9.

When the card 10 is issued, the feed system 2 rotates the feed shafts 2a, 2b, 2c in the CCW direction by the transport system drive unit 1 to transport the card 10 in the β direction. Gears 4, 5
The gear 5 with the built-in one-way clutch 6
Since the wheel idles in the W direction, no drive is transmitted to the spiral spring shaft 7. Therefore, the spiral spring 8 is not reversely wound.

When an abnormality such as a power failure or a motor failure occurs after the card 10 is sucked and the card 10 remains in the apparatus, the power supply to the solenoid 13 is cut off, and the rod 15 pushes the claw 12 by the return spring 14 to cause the ratchet. The wheel 11 becomes rotatable, the charged spiral spring 8 is opened, the spiral spring shaft 7 rotates CW, and the gear 5 is locked by the one-way clutch 6, so that the feed shaft 2 is rotated CCW to rotate the card 10 in the β direction. To be discharged.

[0038]

As described above, according to the present invention, since the card is forcibly ejected by using the energy stored in the spiral spring, a battery and a capacitor as in the prior art are not required. It has the effect of lightening and weight saving.

Further, since the operation of releasing the clamp of the driven roller becomes unnecessary, there is no case where the card cannot be returned without performing the releasing operation. In addition, since the release operation is not performed in a normal state, an unexpected failure is not caused. Further, there is an effect that simplification of the mechanism and reduction of the number of parts can be achieved, and an inexpensive card processing device can be provided.

Furthermore, even if an abnormality such as a power failure or motor failure occurs at the time of issuing the card, no energy is stored in the spiral spring, so that the card is not issued unprocessed.
