Abstract
A card reader may include a card insertion port; a card conveying passage; and a card lock mechanism structured to prevent drawing of the card from the card insertion port. The card lock mechanism may include a motor; a lock member comprising a prevention pawl structured to move between a contact position and a retreated position; and a power transmission mechanism structured to transmit power of the motor to the lock member. The power transmission mechanism may include a final gear which is disposed on a most lock member side in a transmitting direction of power from the motor to the lock member. The lock member may include a sector gear which is engaged with the final gear.
Claims21
A card reader for use with a card, the card reader comprising:
- a card insertion port into which the card is inserted and from which the card is ejected;
- a card conveying passage where the card inserted from the card insertion port is conveyed;
- and
- a card lock mechanism structured to prevent drawing of the card from the card insertion port when the card is abnormally stopped in the card conveying passage and the card is clogged in the card conveying passage;
- wherein the card lock mechanism comprises:
- a motor;
- a lock member comprising a prevention pawl configured to contact with the card for preventing drawing of the card and structured to move between a contact position where the prevention pawl is contacted with the card and a retreated position where the prevention pawl is retreated from the card conveying passage by power transmitted from the motor;
- and
- a power transmission mechanism structured to transmit power of the motor to the lock member;
- wherein the power transmission mechanism comprises a final gear which is disposed on a most lock member side in a transmitting direction of power from the motor to the lock member;
- and
- wherein the lock member comprises a sector gear which is engaged with the final gear.
A card lock mechanism for use in a card reader having a card insertion port into which a card is inserted and from which the card is ejected and a card conveying passage where the card inserted from the card insertion port is conveyed, and the card lock mechanism being structured to prevent drawing of the card from the card insertion port when the card is abnormally stopped in the card conveying passage and the card is clogged in the card conveying passage, the card lock mechanism comprising:
- a motor;
- a lock member which is formed with a prevention pawl configured to contact with the card for preventing drawing of the card and structured to move between a contact position where the prevention pawl is contacted with the card and a retreated position where the prevention pawl is retreated from the card conveying passage by power transmitted from the motor;
- and
- a power transmission mechanism structured to transmit power of the motor to the lock member;
- wherein the power transmission mechanism comprises a final gear which is disposed on a most lock member side in a transmitting direction of power from the motor to the lock member;
- and
- wherein the lock member comprises a sector gear which is engaged with the final gear.
