Abstract

PURPOSE:To enable to confirm the progressing state of the copying and prevent the waste of copying by so arranging the apparatus that, upon completion of copying process on one side, part of the sheet passes the sheet conveyance path which is visible from the outside of the apparatus on the way of sheet conveyance. CONSTITUTION:The passage of the trailing end of a sheet is detected in the state that its leading end is put out of the apparatus, by the sensors 25, 26 disposed in the neighborhood just before discharge rollers 23, 24 on the way of being delivered from a conveyance path 21 to a tray 22 by the discharge rollers 23, 24. The discharge rollers 23, 24 are revolved reverse by the signals thereof to feed the sheet again to the inside of the apparatus. At this time, the front and back of the sheet S are turned over for the purpose of the copying on the 2nd side and with its 1st side faced upward, the sheet S is discharged up to the position projected to the outside of the apparatus. Hence, in this state, the user is able to sufficiently confirm the progressing state of the copying on the 1st side.
