Abstract: A card reader for use with a card may include a data signal circuit pattern structured to transmit at least one of a data signal read from a card and a data signal to be recorded to the card; and a breakage detection circuit pattern structured to detect at least one of its own disconnection and its own short-circuit. The data signal circuit pattern is disposed within a protected region that is a region surrounded from all directions by the breakage detection circuit pattern.

Abstract: A card reader may include a conveyance passage; an optical sensor; a first circuit board; a second circuit board; a first cover member; a second cover member; a first frame; and a second frame comprising a conveyance face on a second direction side of the card conveyance passage. The first frame may include a first transmission hole, and the first frame may be attached with one of the first circuit board and the second circuit board. The second frame may include a second transmission hole, and the second frame may be attached with the other of the first circuit board and the second circuit board. The first cover member may be fixed to the first circuit board so as to cover the entire light emitting element; and the second cover member may be fixed to the second circuit board so as to cover the entire light receiving element.

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.

Abstract: Provided is a card reader capable of preventing the illegitimate acquisition of data from the card reader even when a criminal attempts to obtain data illegitimately from the card reader without removing the card reader from a host device. This card reader is equipped with a data signal pattern for reporting signals of data read from a card or for reporting signals of data recorded on the card, and a failure detection pattern for detecting that the card reader has undergone a wire disconnection or has short-circuited. The data signal pattern is arranged in a protected region D, which is a region surrounded on all sides by the failure detection pattern.
