Abstract:
A camera having a data imprinting function, comprising:a motorized film transport device for winding and rewinding a film having consecutive sprocket holes;a sprocket-hole detecting device which detects that each of said sprocket holes passes a predetermined position;a memory in which photographic data of a frame of said film is stored at a shutter release;a data imprinting device which reads out one of said photographic data stored in said memory therefrom to imprint one character of said photographic data on a corresponding frame of said film between two adjacent sprocket holes of said corresponding frame;a film moving amount detector for detecting an amount of movement of part of said film which extends from the trailing edge of the last frame of said film to the end of said film, in accordance with detection of said sprocket-hole detector; wherein said amount of movement, which is detected by said film moving amount detector, is stored in said memory;a frame edge detector which detects said trailing edge of said last frame when said film is rewound by said motorized film transport device in accordance with said amount of movement stored in said memory,wherein said data imprinting device starts imprinting each of said photographic data stored in said memory on a corresponding frame of said film with reference to said trailing edge of said last frame detected by said frame edge detector, in accordance with detection of said sprocket-hole detector.
