Abstract: Disclosed herein is a torque limiter device which is provided with an inner ring and an outer ring and the inner ring and the outer ring operate together to transmit an input torque to an output member constituted of one of the inner ring and the outer ring as long as the torque is not more than a set torque. One of the input member and the output member is provided with an engagement groove, and the other of the input member and the output member is provided with a coil spring for pressing into the engagement groove an engaging member which is to engage with the engagement groove. When the input torque applied to the input member exceeds the set torque level, the engaging member deforms the coil spring to disengage from the engagement groove, resulting in the input torque not being transmitted to the output member.

Abstract: A sheet feeder superior in performance of sheet conveyance, suitable for downsizing, and improved in usability. The sheet feeder comprises a roll holder having a roll mounting section and a cover member attached to the roll holder. The cover member is rotatable around the roll mounting section and automatically conveys a sheet with a pullout portion of the sheet of a roll put between a receiving section formed in the lower portion of the cover member and a feeding roller.

Abstract: A rolled paper feeding device includes a holder body which rotatably supports a rolled paper, a cover part where one end of which is rotatably supported in a contacting and separating direction with respect to the rolled paper and the other end of which abuts with the rolled paper, a feed roller which is provided in the cover part for feeding a paper of the rolled paper, and a drive part which is provided in the cover part for rotationally driving the feed roller. The feed roller is arranged on the other end side with respect to the center of the rolled paper. A control part for controlling the drive part may include a first and a second switches, which can provide three different lengths of the paper to be fed out of the rolled paper.

Abstract: An IC card reader comprises a card driving path through which a proximity IC card having a card side terminal as a non-contact type input/output terminal can be driven. The card side terminal is capable of providing and receiving electrical signals. A reader side terminal is positioned opposite the card side terminal at a stop position of the proximity IC card. The reader side terminal is capable of providing and receiving electrical signals for communication with the card side terminal. A card pressing member is provided opposite the reader side terminal, upon interposing the proximity IC card therebetween, for pressing the proximity card toward the reader side terminal. Other embodiments of the IC card reader are described.
