A winding machine (10) for winding and/or unwinding band-shaped or strip-like material (12) has at least one rotary plate (16), which is arranged on a pivot arm (24) and can be driven by means of at least two opposite coupling elements (20, 22), at least one coupling element (20) being associated with the rotary plate (16), and the rotary plate (16) being transferrable by means of a pivot device (30) between at least one decoupled state and at least one coupled state. Because the coupling elements (20, 22) can be positioned opposite one another in a coupling position in a sensor-based manner, this allows a coupling process which is as wear-free as possible.

A supply device for a roll medium includes a drawer-type lower holding unit configured to support a shaft of a roll medium to hold the roll medium, and a guide member configured to be pressed in a direction toward the shaft from below to come into contact with the roll medium held by the lower holding unit, and be displaced in accordance with a change in an outer diameter of the roll medium. In addition, the lower holding unit is configured to be drawn from a main body of the supply device in a first direction. When the lower holding unit, in a drawn-out state, is stored in the main body of the supply unit, the guide member comes into contact with the roll medium. The guide member is caused to be retracted downward from a travel path of the lower holding unit against a force pressing upward from below.

A sheet stacking device includes a stacker, a detector, a blower, and a moving device. A sheet is stacked on the stacker. The detector detects a stacking amount of the sheet on the stacker. The blower blows air to the sheet stacked on the stacker. The moving device moves the blower with respect to the stacker based on the stacking amount of the sheet detected by the detector.

A replaceable stack sheet replaceably provided in a medium integration/separation device to guide integration of a medium according to an embodiment includes a body which is coupled to a rotary shaft and in which a plurality of support shafts are spaced apart from each other in a circumferential direction, and a plurality of sheet pieces having ends rotatably coupled to the plurality of support shafts.

A sheet conveyance apparatus (26) includes: a first conveyance unit (70a), a second conveyance unit (70b) disposed below the first conveyance unit (70a) and including a second upper conveyance guide (75) and a second lower conveyance guide (77), and an apparatus main body, wherein the second conveyance unit (70b) can be drawn out to a front side of the apparatus main body along a front-and-rear direction perpendicular to a sheet conveyance direction, the second upper conveyance guide (75) includes: a guide main body part (75b) turnable upward and downward with respect to the apparatus main body with a rear end edge as a turning support shaft and a front end edge as a turning end; and a movable guide part (75c) coupled to the turning end of the guide main body part (75b) via a hinge part (75d) in a turnable manner.

A sheet conveyance guide includes a guide portion, a first thrust direction retainer, and a second thrust direction retainer. The guide portion is configured to guide a sheet. The first thrust direction retainer includes a first engagement portion configured to engage with a shaft of a sheet conveying roller configured to convey the sheet, and a guide releaser configured to be operated by a user to release engagement of the first engagement portion with the shaft of the sheet conveying roller. The second thrust direction retainer includes a second engagement portion configured to engage with the shaft of the sheet conveying roller.

A printer includes a case including an input port for rolled paper, a cover provided to be rotatable between a closed position of the input port and an open position of the input port, a holding portion that holds the rolled paper, a biasing member that biases the holding portion in a first direction, a stopper mechanism that stops rotation of the holding portion in the first direction, and a linkage mechanism that rotates the holding portion in conjunction with the rotation of the cover. When the cover is in the closed position, the holding portion rotates in the first direction in accordance with an outer diameter of the rolled paper by a biasing force of the biasing member. When the cover rotates from the closed position to the open position, the holding portion rotates together with the cover against the biasing force of the biasing member.

A sheet alignment apparatus includes a supporting portion configured to support a sheet, a first alignment member configured to abut an end portion in a first direction of the sheet supported by the supporting portion and align a position of the sheet in the first direction, a first moving unit configured to move the first alignment member in the first direction, a second alignment member configured to abut an end portion in a second direction of the sheet supported by the supporting portion and align a position of the sheet in the second direction, the second direction being perpendicular to the first direction, and a second moving unit configured to move the second alignment member in the second direction, wherein the first moving unit is disposed below the supporting portion, and wherein the second moving unit is disposed above the supporting portion.

A sheet bundle discharging apparatus K, including: a conveyance unit 66 configured to convey a sheet bundle; a guide unit 72 configured to guide the sheet bundle conveyed by the conveyance unit; a discharging unit 90 configured to discharge the sheet bundle to an outside of the sheet bundle discharging apparatus; and a receiving unit 81 configured to receive the sheet bundle guided by the guide unit, wherein the receiving unit includes: a contact portion 81c with which a leading end portion of the sheet bundle, which is guided by the guide unit, in a moving direction of the sheet bundle is to be brought into contact; and a pushing portion 81b, which is formed integrally with the contact portion, and is configured to push a first surface of the sheet bundle, and wherein the receiving unit is rotatable between a first position and a second position, and is configured to receive the sheet bundle in the first position and rotate from the first position to the second position, thereby allowing the pushing portion to push the first surface of the sheet bundle to place a second surface of the sheet bundle, which is on a side opposite to the first surface, on the discharging unit.

A liftable transport pinch is provided with a simplified construction to enhance lifetime and productivity. This transport device includes at least one roller mounted on an arm, and an actuator connected to a frame for moving the roller between a first and second position. The arm is mounted onto the frame by means of an elastic hinge element. The elastic hinge element provides a simple, cheap, wear-resistant, and easy-to-assembly alternative to prior art solutions.
