Provided is a sheet processing device that includes a guide, a support section, a stacker, and a gate. The guide is provided with a conveyance surface along a conveyance direction of a sheet. The support section is configured to form a conveyance path of the sheet together with the guide. The stacker is provided with a stack surface that supports a surface of the sheet conveyed through the conveyance path. The gate is configured to be able to receive the sheet into the stacker. The gate includes a first extension part and a second extension part. A plurality of first extension parts are disposed at intervals in a direction orthogonal to each of a normal direction of the stack surface and the conveyance direction. The second extension part is disposed to close spacing between two of the adjacent first extension parts in the orthogonal direction.

Sheet processing device

An ink-jet printer includes a sheet feed-in mechanism,for feeding a paper sheet, a rotary drum,having a peripheral surface,of a size larger than the paper sheet to be fed by the sheet feed-in mechanism,, for rotating at a constant speed, a sheet holding system,for holding the paper sheet on the peripheral surface of the rotary drum, a print head,for printing an image by repeatedly ejecting ink onto the paper sheet held on the peripheral surface of the rotary drum,while the rotary drum,performs a predetermined number of rotations, a sheet separator,for separating the paper sheet from the peripheral surface,of the rotary drum, a sheet feed-out mechanism,for feeding out the paper sheet separated by the sheet separator,, a control unit,for controlling the sheet feed-in mechanism,, the rotary drum,, the sheet holding system,, the print head,, the sheet separator,and the sheet feed-out mechanism,. In particular, the control unit,is constructed such that the sheet holding system,, the print head,and the sheet separator,are sequentially driven on the basis of the number of rotations of the rotary drum

Ink-jet printer

A printing medium discharge apparatus used for discharging a printing medium from a rotary drum in an ink jet printer for printing a desired image onto the printing medium by an ink jet while holding the printing medium on the rotary drum, includes a printing medium carry and discharge device and a printing medium press device. The printing medium carry and discharge device carries thereon the printing medium from the rotary drum, on the printing medium an image having been printed, to make a non-image formation surface of the printing medium including no image formation region contact the printing medium carry and discharge device, and discharges the printing medium carried thereon to be moved apart from the rotary drum. The printing medium press device presses an image formation surface including an image formation region of the printing medium carried on the printing medium carry and discharge device, against the printing medium carry and discharge device, thereby to prevent the printing medium from floating up from the printing medium carry and discharge device while the printing medium is discharged by the printing medium carry and discharge device.
