Problems solved by technology

[0011] For example, when a sheet with a convex portion is placed as the second sheet among three sheets, even if it tries to abut against the stopper by the transmission force generated by friction with the uppermost sheet, due to its large weight , so sheets with convex parts may not be conveyed

Embodiment Construction

[0031] Embodiments, features, and aspects of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] The following will refer to Figure 1-11 A sheet processing apparatus and an image forming apparatus including the sheet processing apparatus according to an embodiment of the present invention are described.

[0033] figure 1 An image forming apparatus 1100 according to one embodiment of the present invention is shown. An image forming apparatus 1100 includes an image forming apparatus main body 1000 serving as an electrophotographic copier and a sheet processing apparatus 1500 .

[0034] The sheet processing apparatus 1500 is connected to the image forming apparatus main body 1000, and contains figure 2 Shown is a stapler 1300 for side stitching used as a sheet handling device. Sheets discharged from the image forming apparatus main body 1000 are directly received in the sheet processing apparatus 1500, and can be so-...

Abstract

The invention relates to a sheet processing apparatus and an image forming apparatus. The sheet processing apparatus includes a processing tray configured to stack a sheet to be processed, a sheet overlap unit configured to allow a sheet fed while the sheet to be processed is stacked on the processing tray, to be overlaid and made to wait, first and second bundle conveyance rollers configured to convey the sheet to the processing tray from the sheet overlap unit, and a sheet processing apparatus control unit configured to control an overlap operation in the sheet overlap unit, wherein the sheet processing apparatus control unit determines, based on sheet information relating to the sheet fed to the sheet overlap unit, whether a sheet to be then fed is overlaid on the sheet fed to the sheet overlap unit.

Description

technical field [0001] The present invention relates to a sheet processing apparatus and an image forming apparatus, and particularly relates to a sheet to be conveyed when a tabbed sheet having a tab serving as a tab is superimposed on the sheet in a sheet conveying path. A sheet processing apparatus and an image forming apparatus that improve the alignment grade of an output sheet including a sheet with a convex portion when outputting a sheet bundle. Background technique [0002] Conventionally, a sheet processing apparatus that performs various types of processing on a sheet discharged from a main body of an electrophotographic image forming apparatus for forming an image using toner is installed as an option. Such a sheet processing apparatus is designed to avoid deterioration in productivity when performing sheet processing requiring a relatively long processing time (for example, processing for binding sheets into a sheet bundle). [0003] For example, sheets conveye...
