PURPOSE: To obtain the signal for program searching, etc. at the reproducing of photographing explanation by recording the specific signal in a tape recorder in response to the operation of the camera shutter.

CONSTITUTION: When a shutter operating button 13 is depressed in the state that a switch 7 is held connected to the recording contact R side, source voltage is applied to a multi 14 by way of a diode 15 and the oscillation output of the multi 14 goes through output terminals M1, M7 and is recorded in the tape of the tape recorder provided to the camera by way of a bias circuit and head 2. Hence, by reproducing this recording, the program searching of the explanation at the photographing may be done or this may be used for the frame feeding at the slide projecting.
