    • A film winding-up system for a photographic camera including a film detection switch, a one-frame film winding-up device, a detection switch for detecting completion of an operation of the one-frame film winding-up device, a film advance detection switch for detecting whether a film is properly wound-up or not, a display device having a film frame counter and a control device connected to the film detection switch, the one-frame film winding-up device, the one-frame film winding-up completion detection switch, the film advance detection switch and to the film frame counter. The control device controls the film frame counter to count up the value on the film frame counter when the film is not loaded and at the same time the one-frame film winding-up operation is completed and the control device also controls the film frame counter to count up the value on the film frame counter when the film is loaded and at the same time the one-frame film winding-up operation is completed and further the film advance is properly detected and the control device inhibits the counting-up operation of the film frame counter when the film is loaded and at the same time the one-frame film winding-up operation is completed and further the proper film advance is not detected.
    • 一种用于照相机的胶片清理系统,包括胶片检测开关,单帧胶卷清洗装置,用于检测完成一帧胶卷清洗装置的操作的检测开关,胶片提前检测 用于检测胶片是否正确卷绕的开关,具有胶片帧计数器的显示装置和连接到胶卷检测开关的控制装置,一帧胶卷清洗装置,一帧胶片卷绕装置, 上胶完成检测开关,胶片提前检测开关和胶片框架计数器。 当胶片未装载时,控制装置控制胶片帧计数器对胶片帧计数器的值进行计数,并且同时完成一帧胶卷清除操作,并且控制装置还控制胶片帧计数器 当胶片装载时对胶片帧计数器的值进行计数,同时完成一帧胶片清除操作,并进一步检测胶片提前,并且控制装置禁止 当胶片装载时的胶片帧计数器,同时完成一帧胶卷清除操作,并且进一步检测不到合适的胶片提前。
