御回路。[Scope of Claim for Utility Model Registration] 1. Photographing start signal generating means for generating a photographing start signal; Film presence/absence detecting means for detecting the presence or absence of film and outputting a film presence signal and a film no signal; and a film presence/absence detection means for outputting a film presence signal. If the subject has low brightness, the flash device will fire in response to the shooting start signal, and if no film signal is output, the flash device will fire even if the shooting start signal is generated, regardless of whether the brightness is high or low. A camera flash device control circuit comprising a control means for prohibiting light emission of a camera, further comprising an operation member that outputs an operation signal in response to a manual operation, and the control means outputs an operation signal when the film presence signal and the operation signal are output. When input, the flash device is prohibited from emitting light even if the shooting start signal is generated when the subject is at low brightness, and when no film signal and the operation signal are input, at least when the subject is at low brightness. A flash device control circuit for a camera, characterized in that the flash device causes the flash device to emit light when the photographing start signal is generated. 2 Utility Model Registration Scope of Claim 1 In the camera flash device control circuit, when the no film signal and the operation signal are input, the control means starts the photographing start signal regardless of the brightness of the subject. A flash device control circuit for a camera, characterized in that the flash device causes the flash device to emit light as the flash occurs. 3 Utility Model Registration In the flash device control circuit for a camera according to claim 1, when the control means receives the film no signal and the operation signal, the control means starts the photographing only when the brightness of the subject is low. A flash device control circuit for a camera, characterized in that the flash device causes the flash device to emit light when a start signal is generated.
