Abstract: Card transfer system in which a card is transferred may include transfer roller which touches and transfers the card, and rotary shaft on which transfer roller is fixed, and rotating member rotatably supported on rotary shaft, and drive mechanism coupled to rotating member to rotate rotating member, and clutch mechanism which interrupts the power transmission between rotary shaft and rotating member. Rotating member is rotatably supported on rotary shaft by antifriction bearings. Rotary shaft is rotatably supported by multiple bearings and, at the same time, at least bearing arranged closest to rotating member is a plain bearing or sliding bearing.

Abstract: A carrying roller for a card reader including: a rubber outer peripheral member, which is roughly cylindrical, and forms the outer peripheral side of the carrying roller; and a retention member, which has an outer peripheral surface that abuts the inner peripheral surface of the outer peripheral member and retains the outer peripheral member on the inner peripheral side of the outer peripheral member. The inner peripheral surface of the outer peripheral member has a plurality of protuberances that protrude inward in the radial direction. The outer peripheral surface of the retaining member has a plurality of grooves recessed in the radial direction and engaging with the projections. The height of the projections in the radial direction is no more than 1/3.5 of the radial thickness of the outer peripheral member in sections without projections.

Abstract: A card reader includes a pad-roller supporting mechanism having a pad roller block for supporting a plurality of pad rollers for transporting a card inserted into a card traveling passage in cooperation with a plurality of drive rollers supported by a main-body block. The pad roller block is pivotally supported by the main-body block about pivotal shafts provided in parallel with the card traveling passage so as to be openable and capable of causing each of the pad rollers to come into contact with and move away from each of the drive rollers. A spring member is disposed on the main-body block and a pressing plate supported by the pad roller block and the spring member between an operating region and a nonoperating region of the spring member so as to be capable of being engaged with or disengaged from the pad roller block and the spring member, for imparting to the pad roller block a rotating urging force in a direction in which the pad rollers approaches the drive rollers.

Abstract: A method for controlling an automatic sheet connecting and feeding apparatus in which folded sheets, each of which is folded zigzag in the form of a stack of sheets, are conveyed successively by a plurality of conveying means to a processing means. In order to connect the bottom sheet of a first one of the folded sheets to the top sheet of a second folded sheet following the first folded sheet the top sheet is lifted with a suction device. The step of lifting the first folded sheet includes the steps of pushing the suction device against the top sheet to suction and retain the top sheet, moving the suction device in parallel with the surface of the top sheet and moving the suction device in a direction perpendicular to the surface of the top sheet.
