Abstract
Abstract The present invention relates to a data printing device suited to be built in a compact camera, the device is designed so that optical fibers are provided between the data carrier comprising data figures and the photosensitive film in such a manner that the data light is transmitted through the optical fibers so as to form an image of the data figures on the film plane by means of the image forming lens.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
130 words
A data printing device for a camera comprising: a data figure carrier for carrying figures representing photographing data to be inserted on a portion of photosensitive film simultaneously with a picture image being photographed; data setting means interengaged with said data figure carrier for setting the data to be inserted on a photograph; a light source for illuminating the data figures set by the data setting means; optical means for guiding light flux passing through the set data figures to a film surface; and bundles of optical fibers being provided as optical means for guiding light flux supplied by said light source passing through the set data figures to an optical path of a view finder, one end of each of the optical fiber bundles facing said data figure carrier.
Claim 2
Dependent Claim
130 words
A data printing device for a camera comprising: a data figure carrier for carrying figures representing photographing data to be inserted on a portion of photosensitive film simultaneously with a picture image being photographed; data setting means interengaged with said data figure carrier for setting the data to be inserted on a photograph; a light source for illuminating the data figures set by the data setting means; optical means for guiding light flux passing through the set data figures to a film surface; and bundles of optical fibers being provided as optical means for guiding light flux supplied by said light source passing through the set data figures to an optical path of a view finder, one end of each of the optical fiber bundles facing said data figure carrier.
Claim 3
Dependent Claim
58 words
A data printing device for a camera according to claim 1, wherein said optical fiber bundles provided as said optical means for guiding light flux passing through the data figures to the view finder optical path also constitute a portion of said optical means for guiding said light flux passing through said data figures to the film surface.
Claim 4
Dependent Claim
23 words
A data printing device in accordance with claim 1, wherein the optical fiber bundles being provided in the back cover of the camera.
Claim 5
Dependent Claim
138 words
A data printing device for a camera comprising: a data figure carrier for carrying figures representing photographing data to be inserted on a portion of a photosensitive film simultaneously with a picture image to be photographed; data setting means interengaged with said data figure carrier for setting the data to be inserted on a photograph; a source of light introduced from outside the camera for illuminating the data figures set by the data setting means; optical means for guiding light flux passing through the set data figures to a film surface; and bundles of optical fibers being provided as optical means for guiding light flux supplied by said light source passing through the set data figures to an optical path of a view finder, one end of each of the optical fiber bundles facing said data figure carrier.
Claim 6
Dependent Claim
138 words
A data printing device for a camera comprising: a data figure carrier for carrying figures representing photographing data to be inserted on a portion of a photosensitive film simultaneously with a picture image to be photographed; data setting means interengaged with said data figure carrier for setting the data to be inserted on a photograph; a source of light introduced from outside the camera for illuminating the data figures set by the data setting means; optical means for guiding light flux passing through the set data figures to a film surface; and bundles of optical fibers being provided as optical means for guiding light flux supplied by said light source passing through the set data figures to an optical path of a view finder, one end of each of the optical fiber bundles facing said data figure carrier.
