To stop a variety of sheets and prevent problems generated by colliding sheets, a front stopping device that receives sheets being delivered along a horizontal transport route on a hopper unit and stops the movement in the transport direction includes a plate-shaped buffering member that is brought into direct contact with the front part of a sheet; and supporting members that support the upper end and lower end of the buffering member. The buffering member is formed of a flexible material to absorb the kinetic energy of the sheet by being elastically deformed in a concave surface shape when receiving the front part of the sheet, and the buffering member is supported by being inclined upward or downward by the supporting members such that a restoring force of pushing back the front part of the sheet due to the restoration of the elastic deformation includes a vertical component.

A medium ejecting apparatus includes medium ejecting apparatus includes an ejection roller to eject a medium, a tray to load the medium ejected by the ejection roller, a medium regulating member provided with a load pressing portion on a front-end side thereof to apply a load to the medium ejected on the tray, and provided with an engaging portion on a base portion side opposite to the front-end portion, and a holding member provided with an engaged portion to engage with the engaging portion, to hold the medium regulating member in such a way that the medium regulating member can swing in a vertical direction with respect to an upper surface of the tray, and pivot along a rotation axis in a direction from the base side toward the front-end portion side, according to the ejection of the medium.

An apparatus is provided for positioning a substrate on a support body. The apparatus comprises the support body for supporting the substrate, at least one registration element, wherein said at least one registration element is positioned and arranged for registering the substrate in a preselected position on the support body when brought into a registering state. The apparatus further comprises a registration actuator movably arranged with respect to the support body for selectively arranging a registration element into the registering state.

A sheet stacker including a sheet conveyor arrangement and a stacking bay, wherein sheets delivered by the sheet conveyor arrangement are formed into stacks; the stacking bay including a stacker platform. The stacker platform is provided with a vertical lifting and lowering movement with respect to a stationary supporting structure and is controlled to move downwards while a stack of sheets is formed thereon. The stacker platform supports a stack conveyor configured and controlled to perform at least an evacuation motion, to remove a completed stack from the stacking bay. The evacuation motion of the stack conveyor is oriented such that a completed stack is moved from the stacking bay onto an evacuation conveyor arranged under the sheet conveyor arrangement.

At a printer that feeds a continuous paper unwound from a paper sheet supply unit in a sheet-shape to a printing head portion side via a damper portion, and then prints on a label of the continuous paper, the damper portion is made of a transparent material.

A medium discharge device 3 includes a medium discharge section 30 that discharges a medium M in a discharge direction, a placement section 14 having a placement surface 40 on which the medium M discharged from the medium discharge section 30 is placed; and a medium stopper 45 that is provided at an end section of the placement section 14 in the discharge direction and that restricts movement of the discharged medium M in the discharge direction, wherein the medium stopper 45 rises upright with respect to the placement surface 40, has a first contact surface S1 configured to come into contact with a downstream end of the discharged medium M in the discharge direction, and has a second contact surface S2 that is located above the first contact surface S1 and that is configured to come into contact with a downstream end of the discharged medium M in the discharge direction.
