A sheet conveyor unit is connected to downstream side of an upstream side unit in a sheet conveying direction. The sheet conveyor unit includes a convey guide for receiving a sheet discharged from outlet of the upstream side unit. The convey guide is constituted of a pair of guide members disposed to face each other with a predetermined space therebetween. The guide members have the same shape and include base parts having guide surfaces that form a sheet conveying path when combined to face each other, and inclined parts bent to directions apart from the guide surfaces from one end of the base parts in the sheet conveying direction so as to form a receiving port. The convey guide is attached selectively to one of positions different in at least one of a height direction and the sheet conveying direction with respect to an apparatus main body.

There is disclosed a sheet media processing machine comprising a media inlet to receive sheet media along a feed direction from a first side of the machine and a media outlet to discharge sheet media along a discharge direction towards the first side of the machine. There is a feed mechanism to convey sheet media from the media inlet to the media outlet, and a re-feed prevention element disposed upstream of the media inlet with respect to the feed direction to inhibit recirculation of discharged sheet media along an external recirculation path between the media outlet and the media inlet. The re-feed prevention element is exposed to contact with sheet media and comprises an elastomer. There is also disclosed a feed guide comprising a re-feed prevention element, and a method in which such a feed guide is installed on a sheet media processing machine.

A sheet discharging apparatus includes a first detecting portion provided in an apparatus body and configured to detect a move of a movable member in a state where a movable tray is at an upper limit position in a moving direction of the movable tray, wherein a detection result of the first detecting portion changes depending on a position of the movable tray in the moving direction. In addition, a second detecting portion detects the position of the movable tray in the moving direction, and a control portion, in a case where the second detecting portion detects that the movable tray is at the upper limit position, determines whether a sheet is present on the movable tray based on the detection result of the first detecting portion. When the second detecting portion does not detect that the movable tray is at the upper limit position, the control portion determines that a sheet is present on the movable tray regardless of the detection result of the first detecting portion.

A sheet storage apparatus and a printing apparatus include simplified mechanisms for supporting a sheet and for guiding the sheet. A sheet storage device that can store a sheet discharged from a discharge port of a printing apparatus includes multiple flappers provided below the discharge port and arranged in a width direction of the sheet, each flapper being rotatable between a first posture in which the sheet discharged from the discharge port is guided downward in a gravitational direction by using a first surface, and a second posture in which the sheet is supported by using a second surface being different from the first surface; and a connecting unit which connects the plurality of flappers to one another.

An equipment of accumulation of sheets forms a stack of sheets on an accumulation plane by means of driving belts and diverters arranged along the path of the sheets and jump on the accumulation plane. The height of the jump is modified by shifting vertically the accumulation plane with respect to the diverters according to number and/or thickness of the sheets. The diverters can be shifted according to the length of the sheets to be accumulated, while a series of arrest lugs delimits at the rear the area of collection of the sheets and a forwarding mechanism with a pair of output rollers forwards the stack of accumulated sheets when the lugs are released.

A medium transport device includes a first transport route for discharging a medium processed by a processing unit to an outer side of a housing in which the processing unit is provided, and a second transport route for discharging a medium processed by the processing unit to the outer side of the housing. The housing has an openable/closeable or detachable cover, and at least one of the first transport route and a route forming member constituting the first transport route and at least one of the second transport route and a route forming member constituting the second transport route to be exposed by opening or detaching of the cover.
