A used paper supply device includes a first paper feed unit and a second paper feed unit for feeding used paper and cleaning unit for cleaning a surface of a roller of the paper feed units, in which when the used paper is fed from the first paper feed unit, the surface of the roller of the second paper feed unit is cleaned.

A paper feeding parameter management system may include air paper feeding devices and a management device. Each of the air paper feeding devices may be provided with an air paper feeder which may feed paper by blowing air and by absorption to paper and which may be provided with a paper feeding parameter capable of being switched. Each of the air paper feeding devices may be provided with a paper type information obtaining unit and a hardware processor. The paper type information obtaining unit may obtain paper type information of paper to be fed. The hardware processor (i) may adjust the paper feeding parameter of the air paper feeder and (ii) may transmit the paper type information, device configuration information regarding a device configuration of the air paper feeding device, and the adjusted paper feeding parameter to the management device.

An image forming apparatus includes a housing in which an image forming section is contained and a paper output section into which a sheet of paper on which an image has been formed is ejected. The paper output section includes a paper output tray that supports the front side or back side of the sheet of paper, a back-end supporting member that supports a back end of the sheet of paper in a paper ejection direction, and a paper takeout slot through which the sheet of paper is taken out. The paper output section is provided at the outer edge of the interior of the housing. The housing has an external wall whose inner face side is used as the paper output tray. The paper takeout slot opens upward.

A sheet feeding apparatus includes a sheet supporting portion configured to support a sheet, a feed rotary member configured to feed the sheet supported by the sheet supporting portion, a curved conveyance path through which the sheet fed by the feed rotary member passes and which is curved upward, an upper conveyance path disposed above the sheet supporting portion so as to pass through a sheet and configured to join with the curved conveyance path, and a driven rotary member disposed inside of the curved conveyance path in a curved direction thereof and driven to rotate by the sheet passing though the curved conveyance path.

An image processing apparatus that prevents erroneous use of paper by enabling registration of user identification of a user who can use a paper feed deck in information about each paper feed deck of the image processing apparatus and controlling paper feeding so that just the user associated with the user identification can use a paper feed deck to which the user identification was added.

A cartoning machine including a carton supply station (e.g., a rotary carton supply station, a linear carton supply station, a non-linear carton supply station, or the like) and a handling station operatively coupled to the carton supply station. The carton supply station provides, on a selective basis, cartons, such as carton blanks, pre-formed cartons, or the like. The carton supply station of the cartoning machine provides for movement of magazines with respect to a robot in the handling station that may have a distal end secured in a stationary and fixed location. As such, different magazines with dissimilar cartons may be moved to a picking location adjacent the robot, as dissimilar cartons are required. Further, the cartons within the magazines may be moved to a pre-determined pick-up location such that the robot is repeatably picking a carton from the pre-determine pick-up location.

A sheet conveyance apparatus includes a roller pair having first and second rollers, a roller holder having first and second guided portions, and a guiding portion having first and second guides. The first and second rollers can take a first state where the first roller contacts the second roller with a predetermined force and take a second state where the predetermined force is reduced. A first direction in which the first guide guides the first guided portion is inclined relative to a second direction in which the second guide guides the second guided portion. When viewed in a rotational axis direction of the first roller with the first and second rollers in the first state, an angle formed by a straight line passing through rotational centers of the first and second rollers and the first direction is smaller than an angle formed by the straight line and the second direction.

A sheet cassette includes a housing, multiple cassettes stacked and provided in the housing, and a rotary cam. The cassettes store a recording sheet. The rotary cam includes multiple pins provided at opposite positions across the axis of rotation of the rotary cam. Adjacent cassettes are offset relative to each other in an offset direction. First receiving parts for receiving the pins are provided one in each of the adjacent cassettes at a first end thereof in the offset direction. The rotary cam rotates with at least one of the pins being in at least one of the first receiving parts of the adjacent cassettes to move the cassettes as connected.
