のフイルムカウンタ。[Scope of Claim for Utility Model Registration] 1. A luminescent counting means that is supplied with power from a battery and electrically counts the number of frames taken on a film, and whose counted value is lost when the power supply is stopped due to battery removal;
a photographic frame number display means for displaying a display according to the count value of the counting means; a film detection means for detecting whether or not film is loaded; and control means for displaying a warning signal indicating an abnormality in the count value of the counting means on the display means when loading of the film is detected by the detection means. 2. A film counter for a camera according to claim 1, wherein the warning signal of the control means is a signal for blinking the count displayed by the photographic frame number display means. 3. A film counter for a camera according to any one of claims 1 and 2, wherein the control means permits transmission of a warning signal to the display means upon completion of a predetermined operation of the camera. 4. A film counter for a camera according to claim 3, wherein the predetermined operation of the camera is a film winding operation. 5. The battery includes a small capacity battery that supplies power to the luminance counting means and the control means, and a large capacity battery that supplies power to the counting means, the control means, and the exposure control means, and the control means starts supplying power by the large capacity battery. A film counter for a camera according to claim 1, which permits transmission of a warning signal to the display means only in the following cases.
