Abstract

A card reader includes a card lock mechanism preventing pulling-out of a card jammed in a card conveyance passage, and an operation part for manually releasing lock of the card caused by the card lock mechanism. The card lock mechanism includes a motor, and a lock member which is provided with a blocking pawl for preventing pulling-out of the card and is moved between a contact position where the blocking pawl contacts the card and a retreated position where the blocking pawl is retreated from the card conveyance passage. The operation part includes a rotation member in a tube shape having an inner circumference wall surrounding an output shaft of the motor, and an engaging member provided on the inner circumference wall and extended along a circumferential direction of the output shaft and engageable with an outer peripheral face of the output shaft. The engaging member is elastically deformable.

First claim

What is claimed is:

1. A card reader comprising:
a card lock mechanism structured to prevent pulling-out of a card jammed in a card conveyance passage from a card insertion port; and
an operation part structured to manually release lock of the card caused by the card lock mechanism;
wherein the card lock mechanism comprises:
a motor; and
a lock member, provided with a blocking pawl contacted with the card to prevent pulling-out of the card, the lock member being moved between a contact position where the blocking pawl is contacted with the card and a retreated position where the blocking pawl is retreated from the card conveyance passage by power transmitted from the motor;

wherein the operation part comprises:
a rotation member, having a tube shape and having an inner circumference wall surrounding an output shaft of the motor; and
an engaging member, provided on the inner circumference wall, extended along a circumferential direction of the output shaft and capable of engaging with an outer peripheral face of the output shaft; and

wherein the engaging member is structured so as to be elastically deformable in a direction perpendicular to the output shaft.

2. The card reader according to claim 1 , wherein the rotation member comprises a plurality of the engaging members.

3. The card reader according to claim 2 , wherein the plurality of the engaging members has a rotationally symmetric shape with a center of the output shaft as a rotation center when viewed in a direction where the output shaft is extended.

4. The card reader according to claim 3 , wherein
the engaging member comprises:
a root part, protruded from the inner circumference wall; and
an arm part, extended from one end of the root part in a circumferential direction of the output shaft along the circumferential direction, and

a space is defined between the arm part and the inner circumference wall, and
the arm part is structured so as to be displaceable.

5. The card reader according to claim 1 , wherein the output shaft comprises an applied part to which an instrument capable of turning the output shaft is applied.

6. The card reader according to claim 1 , wherein
the outer peripheral face of the output shaft is provided with a recessed part in a shape corresponding to a tip end of the engaging member, and
the tip end of the engaging member is engaged with the recessed part.

7. The card reader according to claim 1 , wherein an outer peripheral face of the rotation member is configured to be flat.

8. The card reader according to claim 4 , wherein the output shaft comprises an applied part to which an instrument capable of turning the output shaft is applied.

9. The card reader according to claim 8 , wherein
the outer peripheral face of the output shaft is provided with a recessed part in a shape corresponding to a tip end of the engaging member, and
the tip end of the engaging member is engaged with the recessed part.

10. The card reader according to claim 9 , wherein an outer peripheral face of the rotation member is configured to be flat.
