To provide a sheet post-processing apparatus enabling a sheet to be aligned in a predetermined collection position irrespective of the basis weight of the sheet and image formation surface in dropping and collecting the sheet onto a tray from a sheet discharge outlet, the apparatus has a tray for collecting a sheet from the sheet discharge outlet, and a sheet discharge rotating body for transferring the sheet that is carried out to the tray toward a sheet end regulation member, and is configured to be able to adjust the timing of shifting the sheet discharge rotating body to an operation position engaging in the sheet from a withdrawal position above the tray corresponding to image formation conditions of the sheet.
摘要:
A sheet post-processing device includes a conveying section that conveys a paper sheet; a punch section that punches punch holes in the paper sheet conveyed by the conveying section; a stacker section that stores the paper sheet in which the punch holes are punched by the punch section; a binding section that binds a paper sheet bundle stored in the stacker section with a binding member; and a controller that controls the above sections. The controller selectively performs a ring binding mode and a direct binding mode. The ring binding mode is a mode in which punch holes are punched in the paper sheet by the punch section and then the binding member is made to penetrate the punch holes for binding. The direct binding mode is a mode in which the binding member is directly driven into the paper sheet bundle without punching the punch holes in the sheet.

A sheet post-processing device includes a conveying section that conveys the paper sheet, a punch section that punches punch holes in the paper sheet conveyed by the conveying section, a stacker section that stores the paper sheet in which the punch holes are punched by the punch section, a stopper section that regulates a conveying direction leading end of the paper sheet stored in the stacker section; a binding section that binds the paper sheet bundle whose leading end is regulated by the stacker section, and a folding section that folds the paper sheet bundle bound by the binding section at a predetermined folding position. The punch section punches the punch holes at the front and rear of the folding position in the sheet conveying direction, and the binding section binds the paper sheet bundle with a paper-made staple by making the paper-made staple penetrate the punch holes. With this configuration, there can be provided a sheet-post processing device capable of easily generating a booklet for simple ring binding.

A sheet processing device conveys a paper sheet onto which an adhesive is applied, and includes a bonding member that applies adhesives onto the conveyed paper sheet at intervals in a sheet width direction; and a protruding guide that is positioned on a conveying path, downstream of the bonding member in a sheet conveying direction, and guides the paper sheet, facing an adhesive-applied surface of the paper sheet. The protruding guide is positioned between sheet width direction lines of the adhesive-applied position and includes a protruding portion protruding into the conveying path. With this configuration, it is possible to suppress the adhesive from being adhered to a device component even in a configuration in which an adhesive-applied paper sheet is moved inside the device to make a sheet jam due to the adhesion less likely to occur.
摘要:
A post-processing apparatus for transferring sheets from a sheet carry-in port to a first post-processing section and a second post-processing section to execute post-processing such as stapling and sheet folding on the sheets, includes a sheet carry-in path located in a substantially horizontal direction. The sheets fed to the carry-in port are sequentially transferred to a predetermined sheet discharging port. A first switchback conveying path branches off from the sheet carry-in path so as to reverse a sheet conveying direction. The first post-processing section connected to the first switchback conveying path executes the post-processing on the sheets. A second switchback conveying path branching off from between the carry-in port and sheet discharging port of the sheet carry-in path is upstream of the first switchback conveying path so as to reverse the sheet conveying direction. The second post-processing section is located downstream of the second switchback conveying path.
摘要:
A sheet processing device performs saddle stitching binding a bundle of stacked paper sheets, and includes a stacker section temporarily stacking conveyed paper sheets substantially vertically; a stopper regulating the paper sheets stacked in the stacker section; a first binding section provided in the stacker and saddle-stitching, with a metallic staple, a paper sheet bundle regulated by the stopper at a binding position around a center of the paper sheet bundle in a sheet conveying direction; a second binding section saddle-stitching, without using the metallic staple, the paper sheet bundle being regulated by the stopper at the binding position around the center of the paper sheet bundle in the sheet conveying direction; and a folding section folding in half the paper sheet bundle regulated by the stopper at a folding position at which the paper sheet bundle is bound by the first binding section or second binding section.
摘要:
To provide a sheet processing device that performs saddle stitching processing that binds a bundle of stacked paper sheets at a position around a center thereof and then folds in half the paper sheet bundle at the binding portion, the device being capable of selectively performing both saddle stitching using a metallic staple and saddle stitching not using the metallic staple for environmental protection and capable of reducing a size.A sheet processing device includes a stacker section that temporarily stacks conveyed paper sheets in a substantially vertical attitude, a stopper that regulates the paper sheets stacked in the stacker section, a first binding section that is provided in the stacker and saddle-stitches, with a metallic staple, a paper sheet bundle at a binding position around a center of the paper sheet bundle in a sheet conveying direction, a second binding section that saddle-stitches, without using the metallic staple, the paper sheet bundle at the binding position around the center of the paper sheet bundle in the sheet conveying direction, and a folding section that folds in half the paper sheet bundle. An interval between the second binding section and folding section is set smaller than an interval between the first binding section and folding section.
