Abstract
PURPOSE:To obtain a remote control signal receiver for a camera, which can prevent malfunction caused by external noise as much as possible, by installing a reception angle varying means for varying the reception angle of a remote control signal by a receiving means according to the information of focal distance. CONSTITUTION:When the information of the focal distance of the photographing optical system of the camera is inputted from a switch interface circuit 7, a controller 6 sets the photographing optical system an at the same time outputs a signal corresponding to the focal distance to the reception angle varying circuit 9. Then, the reception angle varying circuit 9 drives a motor 5 and moves a fixing member 3 which meshes with the motor 5 through a gear 4 in the optical axis direction of the photographing optical system so as to control the position in the optical axis direction of a photodetector 2 to obtain a light receiving angle corresponding to the photographic viewing angle at that time. Thus, the malfunction caused by the external noises can be prevented as much as possible while securing a remote controllable azimuth which is the minimum of necessity.
