Abstract

PURPOSE:To realize a copying machine which is operated at a high speed, by constituting so that a sheet original is automatically discharged to the outside from a free space of the upper part of a platen as an original tip matching member remains fixed to the upper surface of the platen. CONSTITUTION:An original conveying belt 13 is bent in the direction separating from the surface of a platen 11, at a position which is this side a little of an original tip matching member 12, and forms a free space 18 which does not restrain a tip part 4a of a sheet original 4. The sheet original 4 is inserted between the platen 11 and the conveying belt 13, the tip part 4a stands still at a position where it has contacted with the original tip matching member 12, and copying is executed. After that, when the conveying belt 13 is driven again, the original tip part 4a is pressed strongly by the matching member 12, forms a loop 4a' in the free space 18, and the original is released from the matching member 12 by its elasticity and is discharged automatically.
