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.
