Abstract
Abstract A character image display apparatus in a film device with a lens mounted thereon or a camera is constructed such that a hole is provided on a reflector in a flash unit provided on a body of the camera, one end of a photoconductor is fixed to the hole and the other end thereof is connected to a diffusion block disposed so as to face an exposure window on the body, and a display device in which a positive film of a display image such as a character image sticked on a plane of the diffusion block is disposed in front of a film in fixed relationship to a shading corrugation within an exposure portion of the camera body, whereby when photographing is performed, a light ray from the flash unit is introduced by the photoconductor and a display image such as a character mark is simultaneously exposed simultaneously exposed as a part of a photographing image with light rays uniformed by the diffusion block.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
181 words
A character image display apparatus for a camera, comprising: a camera body having a film exposure portion and a film plane; a flash unit having a reflector for illuminating a subject being photographed, the flash unit being housed on the camera body; a light guide having an end thereof connected to the reflector through a hole in the reflector, thereby light emitted from the flash unit being transmitted through said light guide; a diffusion block fixed to the camera body within the exposure portion of the body, the diffusion block having a display plane substantially parallel to the film plane of the camera body, and a positive film of a display image being disposed on said display plane and thereby facing the film plane of the camera body, and an opposite end of the light guide disposed in the diffusion block such that during the photographic process light from the flash unit is introduced through the light guide to the diffusion block to uniformly illuminate the display image and thereby the display image being simultaneously photographed with a subject being photographed.
Claim 2
Dependent Claim
181 words
A character image display apparatus for a camera, comprising: a camera body having a film exposure portion and a film plane; a flash unit having a reflector for illuminating a subject being photographed, the flash unit being housed on the camera body; a light guide having an end thereof connected to the reflector through a hole in the reflector, thereby light emitted from the flash unit being transmitted through said light guide; a diffusion block fixed to the camera body within the exposure portion of the body, the diffusion block having a display plane substantially parallel to the film plane of the camera body, and a positive film of a display image being disposed on said display plane and thereby facing the film plane of the camera body, and an opposite end of the light guide disposed in the diffusion block such that during the photographic process light from the flash unit is introduced through the light guide to the diffusion block to uniformly illuminate the display image and thereby the display image being simultaneously photographed with a subject being photographed.
Claim 3
Dependent Claim
16 words
The character image display apparatus of claim 1, wherein said display image is a character image.
Claim 4
Dependent Claim
23 words
The character image display apparatus of claim 1, wherein said positive film is adhesively adhered to the display plane of the diffusion block.
Claim 5
Dependent Claim
38 words
The character image display apparatus of claim 1, wherein the opposite end of the light guide in the diffusion block has a light dispersion plane which is disposed substantially parallel to the display plane of the diffusion block.
Claim 6
Dependent Claim
23 words
The character image display apparatus of claim 4, wherein the light dispersion plane is oblique to the longitudinal axis of the light guide.
Claim 7
Dependent Claim
24 words
The character image display apparatus of claim 4, wherein the light dispersion plane is substantially perpendicular to the longitudinal axis of the light guide.
