no. 1 approach

[0175] refer to Figure 6 The first embodiment will be described. In the aforementioned post-processing apparatus B, when stacking sheets on the processing tray 24, a positioning reference (Sp) for positioning the sheets at a predetermined processing position (staple position) P is provided, and a stapling processing mechanism is arranged. 49 so that the binding process is performed on the sheets positioned on the reference.

[0176] In the illustrated first embodiment, the above-mentioned positioning reference Sp is configured to be able to select the sheet regulating position of the sheet end regulating member 26 between the standard 1 ( Sp1 ) and the standard 2 ( Sp2 ).

[0177] Therefore, as shown in (d) of the figure, the sheet end restricting member (collision stopper) 26 is supported by the bottom of the processing tray 24 so as to be movable (slidable) in the sheet feeding direction (vertical direction in the figure).

[0178] The sheet end regulating member 26 is co...

no. 2 approach

[0189] right Figure 7 The second embodiment shown will be described. The structure in this figure shows the case where the regulating mechanism for positioning the sheet on the processing tray 24 is set so that "the pair of left and right side edge regulating members 27 can be moved between the first reference Cp1 and the second reference Cp2". .

[0190] A case where the sheet is positioned at the processing position on the basis of the illustrated center will be described. A pair of left and right side edge restricting members 27 are supported by the processing tray 24 so as to be movable in the width direction. In the illustrated structure, each side edge restricting member 27a, 27b is slidably fitted into a guide groove (not shown) arranged on the bottom surface of the processing tray 24 .

[0191] An alignment motor M1 (a pair of left and right drive motors in the illustrated configuration) and a transmission mechanism 56 (a rack-and-pinion mechanism, a pulley mechani...

Abstract

To provide a sheet binding processing apparatus for enabling strong binding strength or weak binding strength to be selected in a neat sheet posture to perform binding processing in applying narrow pressure to a plurality of sheets with concavo-convex-shaped pressurizing surfaces to perform the binding processing, in positioning sheets in a binding position for press-binding the sheets with the concavo-convex-shaped pressurizing surfaces that mutually mesh to perform the binding processing, it is possible to set an engagement area of the sheets and the pressurizing surfaces in two or more different steps with positioning references or by shifting a position of a binding processing section in the direction for passing over an edge side of the sheets to perform the binding processing.

Description

technical field [0001] The present invention relates to a sheet post-processing device for stapling a plurality of sheets, and relates to an improvement of a stapling processing mechanism capable of adjusting stapling strength. Background technique [0002] Generally, such a stapling processing device is known as a device that performs stapling processing on a sheet bundle supported on a paper stage (sheet supporting surface), and as a post-processing device of an image forming system, and the like. [0003] As the binding processing mechanism, a mechanism for binding sheet bundles with staples (staple binding mechanism) and a mechanism for pressing sheet bundles with a pressing surface having a concave-convex surface to perform pressure-bonding binding (pressure-bonding binding mechanism) are known. [0004] In a crimp binding mechanism that binds a bundle of sheets without using metal staples, the bound sheets can be easily disassembled and separated, and is selected as a ...
