Abstract
The present invention provides a sheet process apparatus comprising a sheet discharge means for discharging a sheet, a first stacking means for stacking the sheet discharged by the sheet discharge means, a bundle discharge means for discharging a sheet bundle rested on the first stacking means, and a second sheet stacking means for stacking the sheet bundle discharged by the bundle discharge means. Wherein the number of sheets in the sheet bundle to be discharged onto the second stacking means is selected to become smaller, when a sheet size in a sheet conveying direction is great, than when a sheet size in the sheet conveying direction is small.
Claims12
A sheet process apparatus comprising:
- sheet discharge means for discharging a sheet;
- first stacking means for stacking the sheet discharged by said sheet discharge means;
- bundle discharge means for discharging a sheet bundle rested on said first stacking means;
- and
- second stacking means for stacking the sheet bundle discharged by said bundle discharge means,
- wherein when a sheet stack is stacked on said second stacking means, a plurality of sheet bundles are successively piled up to form the sheet stack, and
- wherein a number of sheets in the sheet bundle to be discharged onto said second stacking means when a length of the sheet in a sheet conveying direction is a large size is smaller than a number of sheets in the sheet bundle to be discharged onto said second stacking means when a length of the sheet in the sheet conveying direction is a small size.
An image forming apparatus comprising:
- image forming means;
- sheet discharge means for discharging a sheet on which an image has been formed;
- first stacking means for stacking the sheet discharged by said sheet discharge means;
- bundle discharge means for discharging a sheet bundle rested on said first stacking means;
- second stacking means for stacking the sheet bundle discharged by said bundle discharge means;
- sheet size detecting means for detecting a size of the sheet;
- and
- sheet number counting means for counting a number of sheets discharged onto said first stacking means,
- wherein when a sheet stack is stacked on said second stacking means, a plurality of sheet bundles are successively piled up to form the sheet stack, and
- wherein a number of sheets in the sheet bundle discharged from said first stacking means to said second stacking means when a length of the sheet in a conveying direction is a large size is made smaller than a number of sheets in the sheet bundle discharged from said first stacking means to said second stacking means when a length of the sheet in the sheet conveying direction is a small size on the basis of a detection result of said sheet size detecting means and a counting result of said sheet number counting means.
