Sheet finishing apparatus
First Claim
1. A sheet finishing apparatus for post-processing sheets of paper after image forming comprising:
- a gate for taking in sheets of paper ejected from an image forming apparatus through a taking-in port and switching to either of a first conveying path for post processing or a second conveying path for non-post processing to convey said sheets of paper, a tray attached to an upper part of said sheet finishing apparatus by a link mechanism which can rotate between a first height position for storing said sheets of paper ejected via said second conveying path and a second height position away from said upper part and has an angle of inclination almost fixed at either of said height positions, a sheet guidance member for supporting one of a pair of rollers for clamping and conveying said sheets of paper passing said first conveying path and rotating between a first position where said one roller makes contact with another roller and a second position away from said another roller, a connection member for connecting said link mechanism and said sheet guidance member so as to set said sheet guidance member at said first position when said tray is at said first height position and set said sheet guidance member at said second position when said tray is at said second height position, a processing mechanism for post-processing said sheets of paper conveyed via said first conveying path, and an ejection mechanism for ejecting said sheets of paper post-processed by said processing mechanism.

Abstract
A sheet finishing apparatus of the present invention has a gate for taking in sheets of paper ejected from an image forming apparatus through a taking-in port and switching to either of a conveying path for post processing or a conveying path for non-post processing to convey the sheets of paper and a tray attached to the upper part of the sheet finishing apparatus by a link mechanism, and the tray can rotate between the height position for storing sheets of paper and the height position away from the upper part and keeps the angle of inclination thereof constant at either of the height positions, and furthermore, sheets of paper taken in from the taking-in port are clamped and conveyed by a pair of rollers, and one of the pair of rollers is supported by a sheet guidance member, and the sheet guidance member rotates in connection with the link mechanism and can cope with paper jamming, if any.
