Abstract: A foreign matter detection device which detects a foreign matter in an inside of a card reader. The foreign matter detection device includes a control part which performs control for causing an imaging device provided in the inside of the card reader to image a space in the inside of the card reader, and a detection part which detects the foreign matter in the space by image analysis based on a captured image obtained by the imaging device.

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.

Abstract: A magnetic head structured to detect whether magnetic data are recorded on a medium or not may include a case provided with an opening part formed in a sensor face which faces a side where the medium is passed, a protection member positioned and disposed in the opening part with the sensor face as a reference, and a magneto-resistance effect element disposed in the opening part in a state that at least a part of the magneto-resistance effect element is covered by the protection member.

Abstract: A card reader may include a card passage; a shutter member to close the card passage; a magnetic head on a rear side of the shutter member reads or records data in a magnetic strip of a card; an electrostatic capacitance sensor on the rear side or the shutter member; a first guide member which structures at least a part of a face on a first direction side of the card passage when one side in a thickness direction of the card passing the card passage is referred to as a first direction; and a second guide member which structures at least a part of a face on a second direction side of the card passage. The first guide member may include insulating material and the second guide member may include conductive material. The electrostatic capacitance sensor may be attached to the first guide member.

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.
