Single perforating unit is enabled to perforate for file binders and to cut milling grooves, while with a simple structure file-binder storage and booklet-binding can be carried out reliably. Configurations include: a convey-in path for sequentially transferring sheets; a stacker for collating into bundles sheets from the convey-in path; and an adhesive-layer applicator for adding an adhesive layer to the spine-closure edge of sheet bundles from the stacker. A perforating unit is provided in along the convey-in path, and a control unit for controlling position and/or number of perforations made by the perforating unit is provided with (1) a first operation mode in which it effects the punching of a predetermined number of holes in the edge of sheets, and (2) a second operation mode in which it effects the formation of a predetermined number of crenulated grooves in the edge of sheets.

Finisher, bookbinder, and imaging system

A bookbinding apparatus for trimming sheets includes an adhesive applying device for applying adhesive to a back of the sheets; a trimming blade disposed in a trimming position; a bunch position changing device disposed in a transport path to change a position of the sheets in the trimming position; a blade receiving member having at least first and second blade receiving areas with different blade receiving surfaces contacting with the trimming blade; a driving device positioning the trimming blade between a cut position for bringing the trimming blade into contact with the blade receiving member and a spaced waiting position; a shift device selectively shifting one of the first and second blade receiving areas to a predetermined trimming position, and a control device for controlling the shift means and the driving means.

Bookbinding apparatus

In one embodiment of the present invention, a sheet post-processing apparatus includes an ejection path that successively feed sheets each with an image found thereon from an ejection outlet. A processing tray is disposed under the ejection outlet to temporarily store sheets fed from the ejection path. A port processing unit performs post processing such as binding and punching. The post processing unit is located under the ejection path and is provided with a cooling fan that sends air toward the post processing unit.

Sheet post-processing apparatus and image formation apparatus

An original feeding apparatus includes a feeder tray for stacking originals, a separating device for separating the originals into a single sheet, and a feeding device for feeding the original to the separating device. The feeding device is raised or lowered between a feeding position where the feeding device contacts an uppermost original stacked on the feeder tray, and a retracted position where the feeding device is separated from the uppermost original. A drive device and a control device are disposed for raising and lowering the feeding device. The control device adjusts a rotating speed of the drive device for raising and lowering the feeding device according to a reading mode, so that the feeding device is lowered at a different speed to touch the uppermost original.

Original feeding apparatus and image reading apparatus

A document reading apparatus and method are provided for outputting an image faithful to a document as possible even if the document is accidentally fed in an oblique fashion on the way of a sheet feeding path. For this purpose, a plurality of document end detecting sensors Sto Sare disposed on the way of the sheet feeding path, and further, a reading controllercalculates a skew quantity &#x3b8; of the document with respect to the sheet feeding pathbased on a signal output from the document end detecting sensor, thereby adjusting a document reading timing in accordance with the skew quantity.
