Abstract

Abstract A camera having, in addition to a real focal length photographing mode, a pseudo focal length photographing mode, namely, a photographing mode in which a part of a photographed image frame of a film is printed at an enlarging ratio different from an ordinary enlarging ratio to obtain a print as if it had been photographed using a telephoto lens. It is provided with means for recording photographing mode information on a frame of a film when the pseudo focal length photographing mode is selected, and a control means which brings a flash light emitting device into an operable condition in response to the selection of the pseudo focal length photographing mode and which actuates the flash light emitting device in synchronism with release of the shutter. An optical axis of a photographing lens and a flash emission tube are spaced from each other, and the pseudo focal length photographing mode can be selected only when a negative film is loaded in the camera.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 148 words
A photographic camera comprising: an object lens; means for selecting a real focal length photographing mode in which a normal range in a frame of a film will be printed on a photographing paper and a pseudo focal length photographing mode in which a range narrower than the normal range in a frame of the film will be printed on a photographing paper; means for emitting flash light to illuminating an object to be photographed, the flash light emitting means having a flash light emitting portion from which the flash light is emitted; and means for controlling a distance from an optical axis of the objective lens to the flash light emitting portion of the flash light emitting means so that the distance when the pseudo focal length photographing mode is selected, is extended in comparison with the distance when the real focal length photographing mode is selected.

Dependent Claim 148 words
A photographic camera comprising: an object lens; means for selecting a real focal length photographing mode in which a normal range in a frame of a film will be printed on a photographing paper and a pseudo focal length photographing mode in which a range narrower than the normal range in a frame of the film will be printed on a photographing paper; means for emitting flash light to illuminating an object to be photographed, the flash light emitting means having a flash light emitting portion from which the flash light is emitted; and means for controlling a distance from an optical axis of the objective lens to the flash light emitting portion of the flash light emitting means so that the distance when the pseudo focal length photographing mode is selected, is extended in comparison with the distance when the real focal length photographing mode is selected.
