Abstract
A card elevating/lowering device for use with cards may include a card storage part in which the cards are stacked and accommodated, and an elevating/lowering mechanism by which the cards accommodated in the card storage part are elevated and lowered. The elevating/lowering mechanism may be provided with a placing table on which the cards accommodated in the card storage part are placed and an urging member which urges the placing table in an upper direction, and a spring constant of the urging member may be substantially equal to a weight per unit thickness of the card.
Claims18
A card elevating/lowering device for use with cards, the device comprising:
- a card storage part in which the cards are stacked and accommodated;
- and
- an elevating/lowering mechanism by which the cards accommodated in the card storage part are elevated and lowered;
- wherein the elevating/lowering mechanism is provided with a placing table on which the cards accommodated in the card storage part are placed and an urging member which urges the placing table in an upper direction;
- and
- wherein a spring constant of the urging member is substantially equal to a weight per unit thickness of the card.
A card carrying-out/carrying-in device in which a card is carried out from or carried into a card storage part in which cards are stacked and accommodated, the device comprising:
- a carrying roller which is abutted with the card to carry the card;
- a counter roller which is oppositely disposed to the carrying roller and urged toward the carrying roller to be abutted with the card carried by the carrying roller;
- a motor which drives the carrying roller and the counter roller;
- and
- a power transmission mechanism which transmits power of the motor to the counter roller;
- wherein the power transmission mechanism is structured so that the counter roller is capable of rotating in same direction as a rotating direction of the carrying roller by power of the motor;
- and
- wherein the power transmission mechanism is provided with:
- a torque limiter which intermits power transmission from the motor to the counter roller depending on a magnitude of the power transmitted from the motor to the counter roller when the carrying roller is rotated in a direction that the card is carried out;
- and
- a one way clutch which disconnects power transmission from the motor to the counter roller when the carrying roller is rotated in a direction that the card is carried into inside.
