Abstract

PURPOSE:To remove easily residual paper caused by paper clogging, etc., by opening and closing a fixing and paper discharge part by making it interlock with an opening and closing operation of a discharge paper carrying part. CONSTITUTION:A discharge paper carrying part 18 and a fixing and paper discharge part 11 are connected by a link 34. When the discharge paper carrying part 18 is opened, the fixing and paper discharge part 11 is also interlocked and opened. The link 34 is supported axially so as to be freely turnable by the discharge paper carrying part 18 through a pin 33, and supported axially by the fixing and paper discharge part 11. Also, the link 34 serves as a stopper, as well, and a pin 32 of the fixing and paper discharge part 11 abuts on the end part of a groove of the link 34, by which the fixing and paper discharge part 11 is detained at a prescribed position. Accordingly, a sufficient space is held between the fixing and paper discharge part 11 and a fixing part 10, and between the discharge paper carrying part 18 and the fixing and paper discharge part 11.
