Description

本発明は、シート処理装置において、固定刃と、前記固定刃の上方に昇降可能に配置され、下降して前記固定刃との間のシート束を前記固定刃と共に断裁処理する可動刃と、前記可動刃の昇降と連動し、シート束を断裁した後の前記可動刃の刃先よりも下方まで、前記固定刃に沿って下降する付着防止部材と、前記付着防止部材を前記可動刃の昇降と連動して昇降させる連動部と、を備えたことを特徴とするものである。 In the sheet processing apparatus, the present invention provides a fixed blade , a movable blade that is disposed so as to be movable up and down above the fixed blade, and that cuts the sheet bundle between the fixed blade and the fixed blade together with the fixed blade, In conjunction with the up and down movement of the movable blade, the adhesion preventing member that descends along the fixed blade to the lower side of the blade edge of the movable blade after cutting the sheet bundle, and the adhesion preventing member in conjunction with the elevation of the movable blade And an interlocking part that moves up and down.

Claims

A fixed blade;
A movable blade that is arranged to be movable up and down above the fixed blade, and that lowers and cuts the sheet bundle between the fixed blade together with the fixed blade;
In conjunction with the raising and lowering of the movable blade , an adhesion preventing member that descends along the fixed blade to a position below the blade edge of the movable blade after cutting the sheet bundle ,
An interlocking part for raising and lowering the adhesion preventing member in conjunction with the raising and lowering of the movable blade;
A sheet processing apparatus comprising:

The sheet processing apparatus according to claim 1, wherein when the adhesion preventing member is lowered by the interlocking portion, the adhesion preventing member is lowered while being elastically pressed against a side surface of the movable blade.

The sheet processing apparatus according to claim 2, wherein the adhesion preventing member is lowered while being elastically pressed against a side surface of the rising movable blade.

When the movable blade cuts the sheet bundle and is positioned on the side of the fixed blade, the adhesion preventing member descends while elastically pressing the movable blade and the side surface of the fixed blade by the interlocking portion. The sheet processing apparatus according to claim 1, wherein:

A transport unit that transports a sheet bundle between the movable blade and the fixed blade;
The adhesion preventing member, before the movable blade is lowered, the sheet processing apparatus according to any one of claims 1 to 4, characterized in that in a position which does not interfere with the conveyance of the sheet bundle by the conveying unit .

The adhesion preventing member is a sheet processing apparatus according to any one of claims 1 to 5, characterized in that are provided along the cutting edge of the movable blade.

An image forming unit for forming an image on a sheet, the image forming apparatus characterized by comprising a sheet processing device according to any one of claims 1 to 6.
