Abstract
PURPOSE: To prevent malfunction and breakage by inputting the assigned exposure condition setting information from strobe to an exposure control circuit only in an operatable state.
CONSTITUTION: When the ASA information voltage from the camera side is applied to a transistor T1, T4 also conducts and the voltage having been applied to the emitter of T4 is applied to the aperture value F11 assigning contact A2 of a select switch S3. When S3 is connected to the aperture value F5, 6 assigning contact A1 while the photometric switch S1 on the camera side is being held turned ON, the ground information is transmitted to the control circuit IC3. When it is connected to the contact A2, the emitter voltage of T4 is transmitted as information. Based on each information, the IC3 sets the aperture value, shutter speed value, etc.
