To reduce a failure in imprinting printing size information, to obtain simple inexpensive structure and to surely imprint the printing size information, even in the dark by imprinting the printing size information on a photographic film with light guided from imprinting optical paths.
In an exposure frame 2a for prescribing the exposure range of the photographic film F, two imprinting optical paths 50 for guiding the light after passing through a photographic lens to the fixed position of the film F are formed. In such a case, it is constituted so that the light after passing through the photographic lens enters into the imprinting optical paths 50, by the opening of a sector and the printing size information is imprinted on the film F with the light guided by the imprinting optical paths 50. By this method, the light after passing through the photographic lens is guided to the fixed position of the film F by the imprinting optical paths 50, so that erroneous covering with a finger at the time of executing photographing is prevented and the failure in imprinting the printing size information can be reduced.
