DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera having a data imprinting function having a data imprinting function for imprinting data such as date on a photographing screen.

[0002]

2. Description of the Related Art Generally, in a conventional camera having a data imprinting function, illumination light from a light emitting element is imaged on a film surface through an imprinting optical system, and data such as date is imprinted on a photographing screen. Be included.

In a conventional camera having a data imprinting function, a predetermined space is provided between the spool chamber and the dark box chamber, and a light emitting element block is disposed in this space. A light emitting element block is arranged behind the AF light projection block section.

[0004]

However, when a predetermined space is provided between the spool chamber and the dark box chamber, and the light emitting element block is arranged in this space, the width of the camera body is required to secure the space. And the size of the camera becomes large.

That is, generally, the sizes of the spool chamber and the dark box chamber are almost determined by the size of the film.
In order to arrange the light emitting element block between the spool chamber and the dark box chamber, it is necessary to secure a predetermined space between them, and the width of the camera body becomes large.

When the light-emitting element block is arranged above the dark box room and behind the AF projection block section, the thickness of the camera body becomes large in order to secure a space. There was a problem of being larger.

In other words, when the light emitting element block is arranged behind the AF light projecting block, the dimension in the thickness direction required for disposing the AF light projecting block and the light emitting element block becomes equal to the arrangement of the taking lens and the dark box chamber. It becomes larger than the required size in the thickness direction, and it becomes necessary to increase the thickness of the camera body.

The present invention has been made to solve such a conventional problem, and provides a camera with a data imprinting function in which light emitting elements can be arranged without increasing the width and thickness of the camera body. The purpose is to:

Embodiments of the present invention will be described below in detail with reference to the drawings. FIGS. 1 to 3 show an embodiment of a camera having a data imprinting function according to the present invention. A spool chamber 33 is formed on one side of a camera body main body 31. In the spool chamber 33, A spool 35 for winding the film F in the direction of arrow A is arranged.

Further, above the camera body main body 31,
A camera main board 37 is arranged, and the camera main board 3
A CPU 38 for performing overall control of the camera is arranged below 7.

Below the camera main board 37, a data imprinting board 39 is arranged. On the lower surface of the data imprinting substrate 39, a plurality of light emitting elements 4 composed of LEDs are provided.
1 are arranged in a line, and a driving circuit 43 for driving the light emitting element 41 is arranged.

The drive circuit 43 is arranged above the upper wall 44 of the spool chamber. Also, the data imprinting substrate 3
9 and the camera main board 37 are connected by connection terminals 48 above the dark box chamber 46.

An imaging optical path 45 is formed below the light emitting element 41 of the camera body 31. An imaging optical system member 47 is disposed in the imaging optical path 45. An opening 31c that opens to the film F side is formed on the side of the projection optical system member 47 of the camera body main body 31.

In FIG. 2, reference numeral 51 denotes a cover member, and reference numeral 53 denotes a back cover. 2 to 4, reference numeral 55 denotes an AF light projecting block disposed above the photographing lens 57.

In the above-described camera with the data imprinting function, the illumination light from the light emitting element 41 passes through the imprinting optical system member 47, then forms an image on the film surface through the opening 31c, and the image on the photographing screen is displayed. Data such as date is imprinted on the area D shown in FIG.

In the above-described camera with a data imprinting function, the light emitting element 41 and the drive circuit 43 are mounted on the lower surface of the data imprinting board 39 formed separately from the camera main board 37, and the drive is performed. Since the circuit 43 is disposed above the upper wall 44 of the spool chamber, the light emitting element 41 can be disposed without increasing the width and thickness of the camera body.

That is, in general, due to the structure of the camera, FIG.
As shown in the figure, the AF projection block 55 is often arranged above the photographing lens 57, while the spool chamber 33 is
If the height is made as low as possible, the AF projection block 55
Thus, an empty space is generated above the spool chamber 33.

Therefore, the portion of the drive circuit 43 requiring the most space on the data imprinting substrate 39 is replaced with the spool chamber 3
By arranging the camera 3 above, an empty space can be effectively used, and the camera can be reduced in size.

Generally, as shown in FIG. 3, a space for providing the connection terminal 48 is necessarily formed at the rear of the AF light emitting block 55 due to the structure of the camera. By arranging the connection terminals 48 in the space, the empty space can be effectively used, and the size of the camera can be reduced.

Further, in general, due to the structure of the camera, as shown in FIG. 3, when viewed from above, the dark box chamber 46 has a square shape, while the spool chamber 33 has a circular shape. Since a substantially triangular space is inevitably formed between the chamber 46 and the spool chamber 33, arranging the light emitting element 41 in this portion makes effective use of the empty space, thereby reducing the size of the camera. Can be planned.

[0023]

As described above, in the camera with the data imprinting function of the present invention, the data imprinting substrate provided with the light emitting element is formed separately from the camera main substrate, and the driving is performed.
Means are to place the data imprinting substrate above the dark box and
Sprue caused by placing it below the main board
Since it is located between the upper wall of the camera room and the substrate for data imprinting , without increasing the width and thickness of the camera body,
There is an advantage that a light emitting element can be arranged.
