Abstract
A sheet processing device has a sheet conveying section for conveying sheets to a sheet processing section. The sheet conveying section has a sheet standby unit including a stacking device for stacking a predetermined number of sheets in a linear state, and a bundle conveying device for conveying the sheet bundle stacked in a linear state, whereby the predetermined number of sheets are conveyed to the sheet processing section after having been stacked in a linear state.
Claims32
A sheet processing device, comprising:
- a sheet conveying section that conveys a sheet from an image forming apparatus;
- a sheet processing section that processes sheets conveyed by said sheet conveying section;
- and
- a sheet inserting device disposed between the image forming apparatus and said sheet processing section, and including a sheet accommodating section that accommodates sheets not to be passed through said image forming apparatus, and a paper feed section that feeds the sheets accommodated in said sheet accommodating section to said sheet conveying section in a predetermined order,
- wherein said sheet conveying section has a sheet standby unit that keeps a predetermined number of sheets from at least one of said image forming apparatus and said sheet inserting device on standby while processing of a preceding sheet bundle at said sheet processing section, and
- wherein said sheet standby unit comprises stacking means for stacking and keeping the predetermined number of sheets one on top of another in a linear state on standby, and bundle conveying means for conveying said stacked sheet bundle to said sheet processing section after processing of said recording sheet bundle is completed.
3 more elements
An image forming apparatus, comprising:
- a recording device that forms an image on a sheet;
- and
- a sheet processing device provided on the downstream side of said recording device in the sheet conveying direction,
- said sheet processing device comprising:
- a sheet conveying section that conveys a sheet from an image forming apparatus;
- a sheet processing section that processes sheets conveyed by said sheet conveying section;
- and
- a sheet inserting device disposed between the image forming apparatus and said sheet processing section, and including a sheet accommodating section that accommodates sheets not to be passed through said image forming apparatus, and a paper feed section that feeds the sheets accommodated in said sheet accommodating section to said sheet conveying section in a predetermined order,
- wherein said sheet conveying section has a sheet standby unit that keeps a predetermined number of sheets from at least one of said image forming apparatus and said sheet inserting device on standby while processing of a preceding sheet bundle at said sheet processing section, and
- wherein said sheet standby unit comprises stacking means that stack and keep the predetermined number of sheets one on top of another in a linear state on standby, and bundle conveying means that conveys said stacked sheet bundle to said sheet processing section after processing of said preceding sheet bundle is completed.
