Title: Copying original feeding-discharging device
Inventor: KOFUCHI KUNIOKI
IPC: B65H9/00
Filed: 1979-04-02
Abstract: PURPOSE: To automatically feed and discharge the original surely with a simple and small-size constitution by performing the positioning and discharging of the original by the detachable pressing member provided to the original holder integral with a reciprocating original platen.  
     CONSTITUTION: When the original 9 is inserted into the insertion port 4 of an original inserter 5, the pressing member 8 of the original holder 6 integral with an original platen 3 is contacted to the platen 3 by way of a detecting sensor 18 and electromganetic solenoid 17, by which the leading end of the original 9 is nipped and the original 9 is fixed to the specified position of the platen 3. Thence, according to the copying switch operation, the platen 3 moves and the original 9 is exposure-scanned by a stationary light source 2 without sliding on the platen 3. When the specified sheet number of copying ends, the member 8 is spaced from the platen 3 by the solenoid 17 and a separator 13 is slide-contacted to the platen 3 by a solenoid 13'. At the resetting of the platen 3, the original 9 is disharged by pinch rollers 12, etc. through an original discharge port 7. This eliminates the need for any belt device or the like.
