PURPOSE:To assuredly prevent a switch from malfunction caused by contact, stain and so on in a sheet discharge apparatus of a copier by operating a magnetic near-by switch by action of a detecting portion for directly detecting jamming of a sheet. CONSTITUTION:A sheet 8 is guided by a guide 9 and passed between a paper discharge roller 10 and a driven roller 11 to be discharged on a tray 20. If jamming is caused in the midway, a detecting portion 3 is pushed by a jammed sheet and moved to a position 3', and an interlocking transmission member 2 is turned on a shaft 16 to move a magnet 4 to a position 4'. When at the time of maintenance and check, a paper discharge unit 1 is turned on a shaft 17 in direction of A, the magnet 4 mounted on the transmission member 2 interlocking therewith, is moved to the right, so as to separate from the magnetic near-by switch 5. Thus, the switch is turned off. |
