Abstract

PURPOSE:To prevent a photographed part of a film from being exposed, by providing an element for detecting that a back cover of a camera is opened, and an element for detecting that a part to be photographed of a film is still left, and winding a film into a magazine by a detection output of both these elements. CONSTITUTION:A counter switch SW1 is off when a display value of a counter is >1, that is to say, at least one film to be photographed is left. Now, when the counter switch SW1 is off, the back cover of a camera is opened, and when a back cover switch SW2 is turned on, both inputs of a NAND gate are H and its output becomes L, therefore, a transistor TR1 is turned on and a motor M is rotated forward. As a result, a film is drawn in as far as its terminal of a magazine and is stored, therefore, even if a back cover of a camera has been opened suddenly in case of a camera of stand-by winding system, no photographed part is exposed.
