Abstract

PROBLEM TO BE SOLVED: To make the outside diameter of the rear end part of a camera photographic lens barrel large by fitting a light emission part so that one side thereof is positioned in a direction along the outside circumference of the photographic lens barrel. SOLUTION: An aperture part 5A is formed between an LED 5 and a film surface and an aperture part 6A is formed between an LED 6 and the film surface. Then, light emitted from the LEDs 5 and 6 are projected on a film by a rectangular pattern corresponding to the shapes of the aperture parts 5A and 6A. The LED 5 whose cross section is rectangular is fitted in such a direction that one long side of the rectangle thereof is positioned in the direction along the outside circumference of the back end part of the collapsibly mounted lens barrel. Besides, the long side is set near to the outside circumference of the back end part of the lens barrel. On the other hand, the LED 6 identically shaped to the LED 5 is arranged so that the short side of the rectangle thereof is positioned in parallel with the feeding direction of the film. Thus, the outside diameter of the rear end part of the photographic lens barrel can be made large in comparison with a camera using a conventional information recorder.

BEST MODE FOR CARRYING OUT THE INVENTION

-First Embodiment- A first embodiment of an information recording apparatus according to the present invention will be described below with reference to FIG.

In FIG. 1, reference numeral 1 denotes a camera cover formed in a shape conforming to the outer shape of the camera, 2 denotes a cartridge chamber provided inside the left side of the camera in FIG. 1, 3 denotes an aperture for defining a film exposure range, LEs 5 and 6 are used to optically print a shape corresponding to the print size on a predetermined portion of each frame of the film from the front side of the camera.
D and 7A are windows for allowing light to enter the autofocus device,
Reference numeral 8 denotes a finder objective window, and reference numeral 9 denotes a spool chamber for winding and storing the film drawn from the film cartridge in the film chamber 2. The LEDs 5 and 6 each include an LED light emitting element housed in a case having a rectangular cross section perpendicular to the optical axis. A two-dot chain line indicated by P protrudes toward the front of the camera at the time of photographing, and is perpendicular to the optical axis of the rear end (the end on the back side of the camera) of the photographing lens barrel provided so as to be retractable except during photographing. The area of the cross section in the direction is shown.

As shown in FIG. 1, an opening 5A is formed between the LED 5 and the film surface, and an opening 6A is formed between the LED 6 and the film surface. Light is projected on the film in a rectangular pattern according to the opening shapes of the portions 5A and 6A. The LED 5 and the LED 6 are not surface-emitting type LEDs, but LEDs having characteristics close to point emission.
, And between the LED 6 and the opening 6A, a sufficient distance is secured for the directional characteristics of light projection of the LEDs 5 and 6, respectively. Spreading over the parts 5A and 6A,
Therefore, the film is uniformly exposed to the same pattern as the openings 5A and 6A.

As a result of mounting the LEDs 5 and 6 with a certain distance from the film surface as a result, when the photographic lens barrel is retracted, the rear end of the photographic lens barrel retreats and the LEDs 5 and 6 and the lens barrel are retracted. And the rear end overlaps in the front-rear direction of the camera.

As shown in FIG. 1, in the first embodiment, the LED 5 having a rectangular cross section is oriented along the outer periphery of the rear end of the lens barrel in which one of the long sides of the rectangle is collapsed. And its long side is close to the outer periphery of the rear end of the lens barrel. On the other hand, the LED 6 having the same shape as the LED 5 is mounted so that the short side of the rectangle is parallel to the film feeding direction.

In the first embodiment, since the long side of the LED 5 is arranged along the outer shape of the rear end of the photographic lens barrel, the outer diameter of the rear end of the photographic lens barrel is determined by the conventional information. The size can be increased as compared with a camera using a recording device. That is, in the conventional information recording apparatus, the direction of the two LEDs is set such that one side of the rectangle is parallel to the film feeding direction.
Are inclined, so in the first embodiment, LE
The area limited by D5 can be retracted to a position further away from the center of the lens barrel. Therefore, the first
In the camera equipped with the information recording device of the embodiment, the diameter of the rear end of the lens barrel can be increased by that much, and the degree of freedom in design increases.

The two-dot chain line Q in FIG. 1 indicates the diameter of the rear end of the taking lens barrel of the camera equipped with the conventional information recording device, and is smaller than the diameter indicated by the two-dot chain line P. As described above, if the information recording apparatus of the first embodiment is used,
The photographing lens barrel can be enlarged by the amount of the shift between the chain line P and the chain line Q.

Second Embodiment A second embodiment of the information recording apparatus according to the present invention will be described below with reference to FIG.

In FIG. 2, reference numeral 1 denotes a camera cover which is an outer shape of the camera, 2 denotes a cartridge chamber provided inside the right side of the camera in FIG. 2, 3 denotes an aperture for defining a photographic exposure area of a film, and 11 denotes an eyepiece window of a finder. , 1
2 is a pressure plate for maintaining a film in a predetermined shape at the time of photographing;
And 14 are LEDs for optically imprinting a shape corresponding to the print size on a predetermined portion of each frame of the film from the back side of the camera, and are mounted on the pressure plate 12 from the back side of the camera. In FIG. 2, R is a liquid crystal display device, which is attached to the pressure plate 12 from the camera rear side,
The display is visible through the transparent part on the back of the camera.

The LEDs 13 and 14 perform printing from the back side of the film via the pressure plate 12. LED on pressure plate
An opening 13A corresponding to the light emitting portion of the LED 13 and an opening 14A corresponding to the light emitting portion of the LED 14 are formed.
Light emitted from the EDs 13 and 14 is transmitted through the apertures 13A and 14A.
A penetrates A and reaches the film surface. Thus, an optical pattern having almost the same shape as the openings 13A and 14A is imprinted on the photographing frame of the film. For the same reason as in the first embodiment, the LEDs 13 and 14 are separated from the film surface to some extent, and as a result, the LEDs 13 and 14 protrude more toward the camera rear than the pressure plate 12.

As shown in FIG. 2, in the second embodiment, the LEDs 13 and 14 have a rectangular shape,
D13 has its short side parallel to the film feeding direction, and LED 14 has its long side parallel to the film feeding direction.
Each is installed. As shown in FIG. 2, the liquid crystal display device R is mounted close to the LED 14,
In the second embodiment, since the LEDs 14 are provided in the horizontal direction in this manner, a larger liquid crystal display device can be attached to the camera than in the case where a conventional information recording device is used. In FIG. 2, S indicates a liquid crystal display device of a camera equipped with a conventional information recording device. As is apparent from comparison with FIG. 5, the size of the liquid crystal display device is limited by vertically arranged LEDs. However, only a small camera liquid crystal display device R using the information recording device of the second embodiment can be used. On the other hand, in the information recording apparatus of the second embodiment, since the LEDs 14 are arranged in the horizontally long direction, a larger liquid crystal display device R can be arranged. Further, L is set so as to avoid interference with other members other than the liquid crystal display device (for example, various electronic elements, substrates, etc.).
The ED 14 can also be oriented horizontally.

In the embodiments and the claims, the LEDs 5, 6, 13 and 14 correspond to the light emitting portion, and the liquid crystal display device R corresponds to the external display device.
