  • Patent number: 11900186
    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.

  • Patent number: 10402705
    Abstract: A card reader may include a card holder and a card ejection mechanism for moving the card holder. The card ejection mechanism includes a connection arm connecting the main body frame with the card holder, a solenoid for bending the connection arm, and an arm urging member urging the connection arm. When the solenoid is switched to a non-energized state, the solenoid pushes the connection arm and the connection arm is changed from an extended posture to a bent posture. The connection arm in the extended posture is restricted from bending to an opposite side to the bent posture side and, in a state that the connection arm is in the extended posture, the arm urging member applies an urging force to the connection arm so that the connection arm is bent to an opposite side to the side of the bent posture.

  • Publication number: 20190164023
    Abstract: A card reader may include a card holder structured to hold a card, a main body frame movably holding the card holder, and a card ejection mechanism. The card ejection mechanism includes a connection arm connecting the main body frame with the card holder, a solenoid to bend the connection arm, and an arm urging member urging the connection arm. When the solenoid is switched to a non-energized state, the connection arm changes from an extended posture to an intermediate posture to a bent posture. The arm urging member applies an urging force to the connection arm so as to bend to the bent posture side in a state that the connection arm is in the intermediate posture. Further, the connection arm pushes the plunger when the connection arm is changed from the bent posture to the extended posture.

  • Publication number: 20190080211
    Abstract: A magnetic card reader is provided and includes the holder which is movable both in the card-inserting direction and the card-ejecting direction in the card pathway. The magnetic card is held in the holder which is energized in the card-ejecting direction. Therefore, when the card latch lever is retracted, the auto eject operation of the magnetic card is implemented. The distance between the card-receiving surface on the holder positioned in the insertion-waiting position and the reading-writing position in the X direction is longer than the length from the edge of the magnetic card on the back side X2 to the edge of the magnetic data recording range on the front side X1. Therefore, the magnetic card is prevented from hitting the card-receiving surface and therefore from receiving impact while the magnetic data recording range on the magnetic card is passing the reading-writing position.

  • Publication number: 20180276424
    Abstract: A card reader includes: a shutter member closing off a card passageway; a shutter urging member urging the shutter member toward a closed position where the card passageway is closed off; and a lever member having: a card contact part with which a card coming into contact in a case where a width of the card is a regular width and a restriction part restricting operation of the shutter member at the closed position; and a lever urging member urging the lever member toward a restriction position where the restriction part restricts the operation of the shutter member. When the card comes into contact with the card contact part, a restricted state of the shutter member by the restriction part is released. When the card comes into contact with the shutter member and then the shutter member is pressed, the shutter member operates for allowing passage of the card.

  • Patent number: 8844709
    Abstract: A card-shaped medium processing device may include an insertion port to which a card-shaped medium is inserted, a medium feeder capable of abutting with a card-shaped medium inserted from the insertion port to carry the card-shaped medium, and a motor for driving the medium feeder. A taking-in maximum value which is the maximum value of an output of the motor at the time of a taking-in operation of a card-shaped medium inserted from the insertion port is set to be smaller than an ejecting maximum value which is the maximum value of an output of the motor at the time of an ejecting operation of the card-shaped medium toward the insertion port. A control method for a card-shaped medium processing device may include the same relationship, i.e., the taking-in maximum value is set to be smaller than the ejecting maximum value.
