Abstract

PURPOSE:To get rid of an accident damaging the surface of a drum, which is caused by an operator's error, by placing a reflector in the axial direction of a rotary drum for winding a form, and confirming by a detection device whether a form exists on the reflector or not. CONSTITUTION:Scanning is started from a start end position of a drum 1, and until recording paper 4 exists in a scanning position, that is to say, until a form detecting sensor 14 is completely turned off, a controlling circuit 26 rotates a sub-scanning motor 22, and forwards fast a sub-scanning base 19. When transmission of a picture signal is continued, in case the rear end of recording paper has been detected, a reflector 5 is exposed, the form detecting sensor 14 is reversed to an on state, the controlling circuit 26 turns off an AND gate 29 instantaneously, stops an input of a demodulated picture signal to a record amplifying circuit 36, stops recording a picture signal, and on the other hand, an AND gate 27 is also turned off, and the sub- scanning motor 22 is stopped.
