A sheet material binding apparatus for binding sheet materials with a cover material by a heat-adhesive bonding agent includes a heating plate on which the spine of the covering material having the bonding agent is placed, the heating plate being used for heating the bonding agent; a guide for supporting the covering material and the sheet materials vertically on the heating plate; a guide driver for moving the guide in a direction of a thickness of a set of the sheet materials to facilitate setting and removing of the covering material and the sheet materials; and a controller for controlling the guide driver.
摘要:
A sheet re-feeding path (32) is disposed substantially horizontally at a location below a fixing unit (14) and an image forming unit. At a location below the sheet re-feeding path (32), sheet decks (3, 4) are disposed horizontally along a sheet conveying direction in the sheet re-feeding path (32). Also, a drawing path (37) for switchbacking the sheet is disposed substantially horizontally between the sheet re-feeding path (32) and the sheet decks (3, 4). A sheet feeding path (7) for feeding the sheet from the sheet deck (3) disposed at an upstream side crosses the drawing path (37) to join to the sheet re-feeding path (32). Accordingly, a space, which is occupied by component parts or devices related to the conveyance of the sheet, can be made compact, whereby sheet capacity can be increased.
摘要:
A rotating force transmitting apparatus includes: a first and a second transmitting devices for transmitting rotating forces to a first and a second rotary members, wherein the first and the second transmitting devices include a first and a second clutches for intermittently transmitting the rotating forces; a common driving device for imparting the rotating forces to the first and the second transmitting devices, wherein the second clutch can be switched from the turned-off state thereof to the turned-on state thereof for rotating the second rotary member when the first rotary member is rotating with the first clutch being turned on; and a permitting device for permitting the transmission of a rotating force only in a normal rotational direction of the driving device to the first transmitting device.
