Abstract

A photographic camera system includes a photographic camera that can successively expose a photographic film in different frame sizes and an automatic printer for automatically printing the processed photographic film exposed with those different frame sizes. The camera varies the width of an exposure opening in the camera body in the film-feed direction and the film is fed a length corresponding to the width of the exposure opening. The photographic camera records an exposure opening position signal indicative of the size of the exposure opening on the photographic film, and the automatic printer automatically prints the photographic film using the exposure opening position signal detected from the photographic film.

Claims13

Dependent claims

A photographic camera for a cartridge type of a photographic film having a cartridge, a film strip, an effective exposure area on the film strip, and holes on one marginal area along an edge of the film strip, the camera comprising:

a camera body;
a first housing provided in the camera body to accommodate the cartridge;
a second housing provided in the camera body to accommodate the photographic film fed from the cartridge, wherein the photographic film has a leading edge formed in a straight line for automatic loading;
a film feeding device provided in the camera body to feed the photographic film between the first housing and the second housing;
a hole detector provided between the first housing and the second housing to detect a hole;
an exposure device provided between the first housing and the second housing to expose an image of a subject on the effective exposure area of the photographic film, wherein an exposing area of the exposure device has a ratio of 9:16;
a recording device provided between the first housing and the second housing to record aspect ratio information selected by a selector switch;
and
a control device provided in the camera body to control the film feeding device in response to the hole detector, wherein a center of the exposing area of the exposure device is located on a center of the effective exposure area being indicated by the hole.

an exposure device provided between the first accommodation portion and the second accommodation portion to expose an image of a subject on the effective exposure area of the photographic film, wherein an exposing area of the exposure device has a ratio of 9:16,
a recording device provided between the first accommodation portion and the second accommodation portion to record aspect ratio information selected by a selector switch, and
a first control device provided in the camera body to control the film feeding device in response to the first detector, wherein a center of the exposing area of the exposure device is located on a center of the effective exposure area being indicated by the hole;
and
a photographic film printer for printing on a photosensitive photographic paper a processed photographic film exposed using the photographic camera, the photographic film printer including:
a printer body,
a light source and a variable mask device disposed on the printer body for exposing the photosensitive photographic paper,
a second detector disposed on the printer body to detect the hole and the aspect information recorded at a predetermined position by the photographic camera and for generating a hole detecting signal and an aspect information signal,
a printing device disposed on the printer body for varying the variable mask in response to a size information signal, and
a second control device disposed on the printer body to determine whether the second detector has correctly detected the aspect information and to generate the size information signal based on the aspect information signal and for controlling the driving of the photographic film in response to the hole detecting signal, wherein a center of the variable mask device corresponds to the center of the exposing area of the photographic camera.
