Problems solved by technology

[0003] However, in the above-mentioned device, it is necessary to bend a saddle-shaped paper loading portion called a saddle, a driver for driving staples, and a staple that passes through the stack of paper driven by the driver. The clincher is accurately positioned at the specified position
In the past, paper bundles with the folded center were arranged on the saddle and then transported between the driver and the clincher for stapling. Therefore, the folding position of the paper bundle might not match the binding position, or positioning was performed for alignment. time consuming to adjust

Embodiment Construction

[0018] figure 1 A sheet processing apparatus equipped with a saddle stitcher in a typical embodiment is shown. Reference numeral 1 denotes a driving unit, and 2 denotes a clincher unit.

[0019] The driving unit 1 includes a driving unit 21 that guides the driver 20 in a slidable manner, a magazine unit (not shown) that stores staples, and a supply unit that supplies staples from the magazine unit to the driving unit. (not shown), a driving drive mechanism (not shown) that drives the driver 20 downward (first direction = clincher unit side) to drive the staples supplied to the driving unit 21 . In addition, the staple driven by the driver 20 has a crown extending in the second direction and two legs bent from both ends of the crown.

[0020] The clincher unit 2 has a built-in clincher 12 that supports and bends the legs of the staples driven out from the driving unit, and a saddle 3 for placing the folded paper stack at the center is integrally formed at the upper end. The ...

Abstract

A sheet processing apparatus equipped with a saddle stitch stapler is provided with: a driver unit (1) configured to drive a staple; a clincher unit (2) configured to clinch the staple driven by the driver unit (1); a saddle portion (3) integrated with the clincher unit (2); and a guide portion (6) configured to guide the clincher unit (2) toward a predetermined position of the driver unit (1), when a center portion (11) of a bundle of sheets (10) is clamped between the clincher unit (2) and a staple striking portion (21) of the driver unit (1) after the center portion (11) of the bundle of sheets (10) is placed on the saddle portion (3).

Description

technical field [0001] The present invention relates to a sheet processing device equipped with a saddle stitcher. Background technique [0002] In US2006 / 0153612A1, a conventional paper processing device equipped with a saddle stitcher is disclosed: a book-folding device is used to fold the paper discharged through the required processing in the image forming device into a book, and the paper to be folded into a book The processed paper is sequentially placed on the saddle-shaped paper loading part and aligned with the folding line position of the paper stack, and the central part of the folding line is aligned by the two-part binding mechanism composed of the staple receiving mechanism and the staple ejecting mechanism. After the staples are driven out and bound, they are cross-cut and ejected. [0003] However, in the above-mentioned device, it is necessary to bend a saddle-shaped paper loading portion called a saddle, a driver for driving staples, and a staple that pass...
