This camera has a built-in screen size switching mechanism that can switch the shooting screen size between a normal size and a panorama size with the vertical height of this normal size limited. Optical recording of imprinted data such as date is made at a predetermined position.

FIGS. 1 and 2 are a longitudinal sectional view around the data imprinting section and a working state of the mask switching drive section as seen from the film side in the normal size photographing state of the camera. 3 and 4 are a longitudinal sectional view around the data imprinting section and a working state of the mask switching drive section as seen from the film side in a panoramic size photographing state of the camera. As shown in FIG. 1 and FIG. 3, the camera has a data imprinting section that incorporates an imprinting optical system, and a mask switching drive section that trims a normal-size and panoramic-size photographic screen.

The imprinting section is supported by the camera body 10 and houses the imprinting optical system.
It is composed of the LED 2 and the separator lens 3 which are the light source of the imprinting data constituting the imprinting optical system. The LED 2 as the light source unit may be an LCD having a backlight. The case 1 has a tubular shape, and the LED 2 is mounted on the rear opening 1a side so as to emit light rays toward the front.
Further, the single separator lens 3 that guides the light beam emitted from the LED 2 in two directions and further forms an image on the image forming surface of the film 11 is held at the front opening 1b side.

The separator lens 3 separates the projected light emitted from the LED 2 into two optical paths and guides it. One is a lens portion 3a for forming a normal size projected data image. The other one is formed of a lens portion 3b for forming a panorama size imprinted data image. On the other hand, the camera body 10 has imprinting openings 10a and 10b of the camera body 10 at data imprinting positions corresponding to a normal photographing screen and a panoramic photographing screen, that is, a non-trimming screen and a trimmed screen, respectively.
