Claims

[Scope of Claim for Utility Model Registration] 1. In a camera that has a film counter that electronically increments and displays the number of shots of film in response to the completion of film winding or the completion of shutter charging, whether or not the camera back is closed. back cover opening/closing detection means for detecting whether the film is being loaded; film loading detection means for detecting whether the film is being loaded; film feeding detection means for detecting whether the film is being fed normally; Depending on the detection outputs of the loading detection means, the back cover opening/closing detection means, and the film feeding detection means, the back cover is closed and no film is loaded, and the back cover is closed and the film is loaded and the film is normal. When the film is being fed, the counting of the film counter in response to the operation of the winding means and the stepwise movement of the displayed value are allowed, and the camera back is closed and the film is loaded, but the film is not being fed normally. 2. A film winding state confirmation device comprising: a control means for controlling said film counter so as to prohibit counting of said film counter and incrementing of a displayed value. 2. The film feeding state confirmation device according to claim 1, which includes an electric winding motor. 3. Initial winding means for automatically winding a predetermined number of films in response to film loading, and the control means is configured to set the count and display value to "1" upon completion of the initial winding operation by the initial winding means. A film feeding state confirmation device according to claim 2, which controls a film counter. 4. The film feeding detection means is a utility model registration request consisting of a switch that repeats opening and closing operations in conjunction with movement of the film by a predetermined amount, and means for detecting whether the open/closed state of the switch changes within a predetermined time. The film feeding state confirmation device according to item 1.
