Abstract
There is provided a sheet post-processing device that has a first tray, outlet rollers, and a control section. The first tray holds sheets for post-processing with respect to the sheets supplied from an image forming device. The outlet rollers discharge the sheet to the first tray. The control section controls a rotational speed of the outlet rollers to be decelerated after a leading end portion of the sheet passes through the outlet rollers and before the leading end portion of the sheet comes into contact with the first tray.
Claims6
A sheet post-processing device comprising:
- a first tray that holds a sheet for post-processing with respect to the sheets supplied from an image forming device;
- outlet rollers that discharge the sheets to the first tray;
- an outlet sensor that detects the sheets passing through the outlet rollers in the vicinity of the outlet rollers;
- a sheet information acquisition section that acquires information related to the sheet from the image forming device;
- a control section that sets, based on the acquired information, a first speed, a second speed, and a transport amount;
- wherein the control section further controls a rotational speed of the outlet rollers, the rotational speed is set to the first speed in response to the sheet being supplied from the image forming device, the rotational speed is decelerated to the second speed in response to a detection of the sheet by the outlet sensor in addition to a determination that the sheet is transported the transport amount, and the deceleration is completed before a leading end of the sheet comes into contact with the first tray.

A method for sheet post-processing in a sheet post-processing device post-processing with respect to sheets supplied from an image forming device, the method comprising:
- transporting the supplied sheets to a first tray;
- and
- decelerating a rotational speed of outlet rollers after a leading end portion of a sheet passes through the outlet rollers for discharging the sheet to the first tray and before the leading end portion of the sheet comes into contact with the first tray.
