PURPOSE:To check the separating and ejecting states of an original and a photosensitive paper during continuous copying by providing a paper detecting means and the like respectively in an original insertion part, an original eject part and a photosensitive paper conveyance path after the separating part. CONSTITUTION:A microswitch SW1 which is actuated by the passage of an original is provided in an original insertion part, a microswitch SW4 in a conveyance path of an original repeat route, and a microswitch SW5 in a photosensitive paper conveyance path from where the photosensitive paper is separated from the original up to a developing part 6. Now, if one of the switches SW4, 5 does not operate owing to the failure in normal separation of an original O and photosensitive paper S and the delivery of these to one conveyance path, and despite the generation of a paper detection signal from, for example, the SW4, an AND gate AND1 does not open, and the data of a DF/F3 is not cleared and goes to a 1, then a monostable multi MM2 generates a pulse once and an alarm is given by means of a buzzer or the like via an abnormal separation eject display device 73; at the same time, abnormality times are counted. With such constitution, the separation and ejected states are checked during continuous copying. |
