Abstract

PURPOSE:To eliminate development and to directly obtain an image of excellent quality by driving a photosensitive coloring body coloring in response to the wavelength of light emitted from a light emitting array in the sub-scanning direction. CONSTITUTION:The photosensitive coloring body 1 such as film for an instant camera can move in the direction of the arrow (a) with the aid of a roll 3. When a CPU 6 detects signals from the three-colored LED array 5 with the aid of an LED control circuit 6, it controls the move of the photosensitive coloring body 1 and its light sensing performed by the LED array 5, and records an image on the body 1. Thus, images can be obtained directly without using a CRT and a developing step.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an image recording device using a light emitting element array.

[Prior art] Conventional film recorders are equipped with a CRT (CRT) in the main body for fishing on boats.
Built-in athode Ray Tube), RG
B is a camera that projects a still image signal onto a CRT and records the projected image on film through a lens.

[Problem that the invention is trying to solve] However,
In the conventional example described above, since the CRT is built into the main body, the size of the machine becomes large and the cost of the main body becomes high.

In addition, in order to take a picture of the built-in CRT screen with a camera,
It is impossible to obtain image quality higher than RT image quality.

Furthermore, in order to actually obtain an image, a developing process was necessary.

[Means for Solving the Problem] According to the present invention, a light emitting element array, a photosensitive coloring body that generates a color corresponding to the wavelength of light emitted from the light emitting element array, and a photosensitive coloring body moving in the sub-scanning direction. By providing a driving means, the photosensitive color body is exposed to light by the light emitting element array and an image can be obtained without going through the process of development.

[First Embodiment] FIG. 1 shows a first embodiment of the present invention. 1 is a photosensitive color body such as film for an instant camera, 3 is a photosensitive color body 1
5 is a three-color LED array, 6 is an LED control circuit, 7 is a CPU (Central
1 Processing Unit), 8 is a roller drive circuit.

When the LED control circuit 6 detects the input of the LED signal, the CPtJ7 controls the movement of the photosensitive coloring body 1 by the roller 3 and the exposure of the photosensitive coloring body 1 by the LED array 5, and displays an image on the photosensitive coloring body 1. It is recorded.

In this embodiment, the three-color LED array emits light in the three primary colors of red, blue, and green, and the color-forming photoreceptor has a color-forming characteristic that develops in the color of the light it receives.

Further, when the three-color LED array emits three primary colors of cyan, macenda, and yellow, the color-forming photoreceptor only needs to have a color-forming characteristic that is complementary to the color of the light it receives.

In this way, LE film such as instant camera film
If a photosensitive color material that develops a color corresponding to the wavelength of the light emitted from the D array is exposed to light by an LED array, an image can be obtained without using a CRT or a developing process.

[Second Embodiment] FIG. 2 shows a second embodiment of the present invention. In this embodiment, in addition to the configuration of the first embodiment, the LED array is also moved in the direction opposite to the arrow a. In Figure 2, 9
1 is an LED array unit, 10 is an LED array unit drive device, and 11 is an LED array unit drive control circuit.

Elements common to those in FIG. 1 are given the same numbers, and descriptions thereof will be omitted.

In this embodiment, a photosensitive color body 1 and an LED array unit 9 are used.
Since it has two drive systems in order to move both of them in the third movement,
Although the drive system becomes complicated, printing speed can be increased.

In this embodiment, the CPU 7 uses the LED control circuit 6 to
When the human power of the D signal is detected, the photosensitive color body 1 is moved in the direction of the arrow a by the roller 3, and the LED array unit 9 is moved in the opposite direction to the arrow a by the LED array unit driving device 10.

[Third Embodiment] FIG. 3 shows a third embodiment of the present invention. 12 is a delay circuit. Elements common to those in FIG. 1 are given the same numbers, and descriptions thereof will be omitted.

This embodiment is a method in which the three color lights are exposed independently without condensing them. A delay circuit 12 provides a time difference in the light emission of the LEDs according to the distance between the photosensitive points and the speed of the photosensitive coloring body 1, and exposes the light to the light.

[Fourth example] FIG. 4 shows the configuration of a fourth embodiment of the present invention.

FIG. 5 is a sectional view of the LED array 5 of this embodiment.

Elements common to those in FIG. 1 are given the same numbers, and descriptions thereof will be omitted.

In this embodiment, from the stage when the LED emits light, arrays of three colors are collected into one bundle and the photosensitive color body 1 is exposed to light.

(Fifth Embodiment) FIG. 6 shows a fifth embodiment of the present invention. 13 is a reflecting mirror. Elements common to those in FIG. 1 are given the same numbers, and descriptions thereof will be omitted.

In this embodiment, the photosensitive color body 1 is exposed to light after being reflected by the reflecting mirror 13. In this example, the photosensitive color body 1
This is useful when you cannot take up enough space vertically.

[Sixth Embodiment] FIG. 7 shows a sixth embodiment of the present invention. 2 is a silver halide film, and 14 is a film case. Components common to those in FIG. 1 are given the same numbers, and description thereof will be omitted.

By using silver halide film 2 as a photoreceptor,
The storage stability of recorded materials is improved, and film costs can also be reduced.
