Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera for capturing an image on a photographic film, and more particularly to an improvement of a camera having an information adding function having a function of transferring arbitrary information on the photographic film.

[0002]

2. Description of the Related Art Conventionally, a camera has been put into practical use in which information of an electronic calendar or an electronic timepiece built in a camera is superimposed on a photographed image by a numeral or the like and photographed on a silver halide photographic film using a liquid crystal or a light emitting diode. I have. Also,
Japanese Patent Application Laid-Open No. HEI 1-30024 discloses a camera for printing information more complicated than numbers such as alphabets on a silver halide photographic film.
No. 1, JP-A-2000-112008 and the like are known. Further, Japanese Patent Laid-Open No. 6-2
Japanese Patent Application Laid-Open No. 31466 discloses a technique in which audio information is converted into an optically readable digital code and printed on a silver halide photographic film. Then, the above-mentioned JP-A-1-300241 and JP-A-2000-112 are referred to.
In the prior art relating to a camera with an information adding function disclosed in, for example, Japanese Patent Application Laid-Open No. 008, JP-A-6-231466, and the like, an LED array in which LEDs are integrated in an array is used as an information imprinting light source. .

[0003]

However, in the prior art of this type, an LED array is used as a light source for imprinting information.
Because of the degree, a spot is not formed on a photographic film unless an optical system such as a lens is used. For this reason, if the optical system is not used, the imprinted information becomes blurred, so that the optical system is indispensable, and there is a technical problem that the camera itself is correspondingly increased in size. Furthermore, L
EDs are difficult to array at high density,
In order to capture higher-density information, it is necessary to capture a large LED array using a reduction optical system, and there is a concern that the camera will be large enough to make it difficult to carry.

SUMMARY OF THE INVENTION The present invention has been made to solve the above technical problems, and a camera with an information adding function that can print high-density information while avoiding an increase in the size of the apparatus itself. Is provided.

[0005]

That is, according to the present invention, as shown in FIGS. 1 (a) and 1 (b), a camera having an information adding function for imprinting information on a photographic film 1 is disposed so as to face the photographic film 1. A semiconductor laser array 2 in which a large number of semiconductor lasers 3 are arranged, a drive control means 4 for driving and controlling the semiconductor laser array 2 in accordance with imprint information while the photographic film 1 and the semiconductor laser array 2 are relatively moved. And a beam based on the imprinting information emitted from the semiconductor laser 3 is guided to the information imprinting area 5 of the photographic film 1.

In such technical means, the photographic film 1 includes not only a silver halide photographic film requiring a developing / printing step but also an instant photographic film not requiring a developing / printing step. Further, the semiconductor laser array 2 only needs to be disposed to face the photographic film 1, but from the viewpoint of preventing damage to the photographic film 1,
It is preferable that the semiconductor laser array 2 and the photographic film 1 are arranged in a non-contact manner. However, when the semiconductor laser array 2 and the photographic film 1 are arranged in contact with each other, for example, a coating layer having a low friction coefficient may be provided at a contact portion of the semiconductor laser array 2 with the photographic film 1 to reduce the contact resistance. preferable. Further, the information imprinted by the semiconductor laser array 2 is characters, digital codes or audio data, so that messages, security codes and voice information can be read from the printed photographic paper or photographic film 1 itself. Good.

Although the semiconductor laser 3 includes various types including an edge-emitting type, the semiconductor laser array 2 uses a surface-emitting type semiconductor laser from the viewpoint of facilitating high density. Preferably, they are arranged. Further, the arrangement of the semiconductor lasers 3 in the semiconductor laser array 2 may be appropriately selected.
The one in which the semiconductor lasers 3 are arranged one-dimensionally, the one in which the semiconductor lasers 3 are arranged two-dimensionally, and the like are used. However, in order to increase the density, the one in which the semiconductor lasers 3 are arranged two-dimensionally is preferable. .

The drive control means 4 controls the photographic film 1
The drive of the semiconductor laser array 2 may be controlled while the semiconductor laser array 2 and the semiconductor laser array 2 relatively move. Here, the requirement for "relative movement" is mainly that the photographic film 1 moves normally, but in the case of using an instant photographic film, the semiconductor laser array 2 may move. It depends. For example, in a mode in which the photographic film 1 can be wound up, the imprinting of information by the semiconductor laser array 2 may be performed during the winding operation of the photographic film 1.

Further, according to the present invention, since the semiconductor laser 3 of the semiconductor laser array 2 can narrow the divergence angle of the beam as compared with the LED, it is basically possible to use an optical system without using an optical system. It is possible to imprint information. For this reason, in the present invention, it is preferable that the semiconductor laser array 2 is opposed to the photographic film 1 without interposing an optical system. In this embodiment, the semiconductor laser array 2 does not use an optical system. In addition, the situation that the device becomes large is effectively avoided. However, for example, when the photographic film 1 is an instant photographic film, an optical system may be used when there is a request to enlarge and project information on the instant photographic film, for example. Therefore, in the present invention, with or without an optical system,
An embodiment using an optical system as necessary is also included.
