An image forming device that executes a preview display of an image to be printed, including: a projector; a panel display; a receiver that receives an instruction indicating whether or not to implement security in the preview display; and a controller that, when an instruction to implement security is not received, controls the projector to execute the preview display according to a first mode that represents the image to be printed at a display area equal to or larger than a defined size, and when an instruction to implement security is received, controls the projector and the panel display to execute the preview display according to a second mode that represents the image to be printed at a display area less than the defined size.

Image forming device

A document reading apparatus includes a conveyance unit for conveying a document and a reading unit for reading an image of a document. In the document reading apparatus, the reading unit includes a platen glass. The conveyance unit allows a cleaning member of a cleaning roller to start contact with the front end in a conveyance direction of a document, on the platen glass, upstream in the conveyance direction from a reading position.

Document reading apparatus and method of controlling the same

An image reading apparatus that feeds a document over a reading glass and optically reads an image of the document at a reading position. A rotary brush type cleaner is located above the reading glass to face the reading position. The cleaner cleans the reading glass while rotating downstream in a document feeding direction. In accordance with a selected reading mode, the frequency of cleaning operations performed by the cleaner, and the rotation speed and the number of rotations of the cleaner are changed.

Image reading apparatus

A sheet accommodating device comprising a sheet-laid tray including a processing tray and a carrying tray; a discharge tray; a sheet accommodating unit; first, second and third sheet transporting paths for leading the discharged sheet to the sheet-laid tray, the sheet accommodating unit and the discharge tray, respectively; a transporting and aligning device for moving the sheet discharged onto the sheet-laid tray toward an alignment reference position; a detector for detecting a vertical position of an upper surface of the sheet on the carrying tray; a tray position adjusting device for adjusting the vertical position of the carrying tray based on a result of detection by the detector ; controller for raising or lowering the carrying tray; and others, the second sheet transporting path extending through the escape position of the processing tray, as well as a sheet processing system including a combination of the sheet accommodating device and an image forming apparatus.

Reciprocating tray for sheet finisher

A finisher distributes image-formed sheets into bins while sorting and stapling the sorted and stacked sheets. The bins are movable vertically pitch by pitch, and the image-formed sheets are distributed so that each bin will store a set from the first page to the last page (sort mode). Further, chucking units are provided to take stacks of sheets on bins set in specified levels out of the bins. The chucking units pinch the respective stacks of sheets and move along the bins in the same direction. The stack of sheets pinched by the lower chucking unit is taken out of the bin for stapling, and then the stapled stack of sheets is moved back onto the bin. The stack of sheets (stapled stack of sheets) taken out of the bin by the upper chucking unit is received by rollers of a convener gate, and the convener gate moves upward to convey the stack of sheets to a non-sort tray.

Finisher with a stapling function

A finisher provided with a punching unit which punches a sheet. The punching unit has five punching rods, a drive shaft which rotates to drive the punching rods, five pairs of circular cam and eccentric cam which are fitted around the drive shaft and a switching board which moves the drive shaft in its axial direction reciprocally at a specified pitch. With a one-pitch movement of the drive shaft in its axial direction, three of the five punching rods (in a three-hole mode) or two of the five (in a two-hole mode) come into contact with the respective eccentric cams, and the three rods or the two rods are moved to make three holes or two holes in a sheet. The selection between the three-hole mode and the two-hole mode is automatically carried out in accordance with the sheet size.

Finisher with a punching function

A staple sorter comprising a large-capacity non-sort tray. Sheets are stacked one by one on a plurality of bins so as to make collated sets of sheets (sort mode), and each set is stapled by a staple unit. A sheet conveyer gate has rollers and is capable of moving vertically. The sheet conveyer gate takes a stapled stack of sheets out of a bin with the rollers when lowered, and ejects the stack onto the non-sort tray after elevated. When ejecting, the gate is elevated to a position which is higher than the uppermost surface of the sheets stacked on the non-sort tray.

Apparatus for stacking and storing sheets

A finisher unit receives a sheet discharged from a copying machine, and in a folding/punching mode, the sheet is conducted into a longitudinal transport path. A fold/punch mechanism includes a pair of folding rollers and a punching rod. The sheet fed into the longitudinal transport path goes in contact, at its leading edge, with a nip portion between transport rollers which are in the state of rotation stop, whereupon a center portion of the sheet is bent to be threaded between the folding rollers and transported to the punching rod. When the bent portion of the sheet is transported by a given distance, the punching rod operates one vertical stroke to provide a punch hole to the sheet.

Image forming system and finisher

A sorter with a plurality of sheet containing bins. The sorter has a first roller and a second roller for transporting a sheet received from a copying machine, and a punching mechanism for punching a sheet is provided immediately after the first roller. Power transmission to the second roller can be connected and disconnected. Immediately before the trailing edge of a sheet passes through the first roller, rotation of the second roller is stopped. Thereby, the trailing portion of the sheet makes a curve, the curve in the sheet caused by buckling of the sheet as the first roller holds the sheet against any further downstream movement, and the trailing edge is regulated by the first roller. In this moment, the punching mechanism is driven to punch the sheet.
