Abstract
Providing a sheet collecting device capable of being downsized and of operating stably wherein a sheet ejecting device that conveys and ejects a sheet in the direction for making the sheet fall along a slanted sheet collecting board is provided, and a leading edge stopper that holds sheets on the sheet collecting board is set so that a trailing edge of the sheet may be at a constant height independently of a sheet size.
Claims8
A sheet collecting device comprising:
- a sheet collecting board including a sheet supporting surface which is inclined so that an upstream side thereof in a sheet conveyance direction when a sheet is carried in is higher than a downstream side thereof;
- an ejecting device which is positioned upstream of the sheet collecting board and which ejects the sheet on the sheet collecting board by conveying the sheet in a direction so that the sheet falls along the sheet collecting board;
- a leading edge stopper which stops the sheet on the sheet collecting board;
- a stopper moving device which changes a position of the leading edge stopper;
- and
- a control device which controls the stopper moving device so that a position of a trailing edge of the sheet when the sheet is carried in on the sheet collecting board is constant regardless of a difference of a size of the sheet.
