Patent number: 11900186Abstract: 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.Type: GrantFiled: July 22, 2022Date of Patent: February 13, 2024Assignee: NIDEC SANKYO CORPORATIONInventors: Mamoru Mizawa, Keiji Ohta, Hiroshige Takeda

Patent number: 10068112Abstract: 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.Type: GrantFiled: June 5, 2017Date of Patent: September 4, 2018Assignee: NIDEC SANKYO CORPORATIONInventors: Shigeki Ozawa, Fumiya Akasu, Hirofumi Kuwaki, Hiroshige Takeda

Patent number: 10049311Abstract: 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.Type: GrantFiled: June 2, 2016Date of Patent: August 14, 2018Assignee: NIDEC SANKYO CORPORATIONInventors: Hirofumi Kuwaki, Hiroshige Takeda, Shinya Miyazawa
