Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to an image recording device.

0002

[Conventional technology]

Conventionally, a light source and a light shutter are provided, and the light from the light source is transmitted through the light shutter. An image recording device has been proposed that uses this transmitted light to form an image on a photosensitive recording medium. . An example of this type of image recording device will be described with reference to FIG.

0003 In this liquid crystal printer 100, microcapsule paper, which will be described later, is photosensitive and pressure sensitive paper. A photosensitive recording medium consisting of color developer paper 8 and color developer paper 8 is used.

0004 Microcapsules are coated on the surface of the support of microcapsule paper 7. The microcapsules contain dye precursors that react with the color developer. . A color developer is coated on the surface of the support of color developer paper 8 and reacts with the dye precursor. The details are described in U.S. Patent No. 4,399,209, etc. are omitted here.

[0005] A halogen lamp 103 is used as the exposure light source, and a reflector is placed above it. 102 are arranged. Further, a condenser lens 1 is provided below the halogen lamp 103. 04 is arranged, and an infrared cut filter 105 is arranged below it. There is. Below the infrared cut filter 5, color filters 122R, 122G, 1 A filter unit 122 consisting of 22B and an LCD 6 are provided.

[0006] Inside the light-shielding cartridge 18, an unexposed microphone is mounted on the cartridge shaft 15. The capsule paper 7 is contained in a rolled state. and the right side of cartridge 18 A feed roller 19 is disposed on the screen, and this feed roller 19 moves the LCD from six directions. The microcapsule paper 7 is exposed to light while remaining stationary below the LCD 6. A latent image is formed. Furthermore, the microcapsule paper 7 is pressed by a pair of pressure rollers 11a, 11b and is wound up on the winding shaft 16.

[0007] A half-moon roller 9 is arranged above the color developer paper 8, and a paper feed roller 10 and a paper feed roller are provided on the left side. A guide 17 is provided. Further, a heat fixing device 12 is provided below the color developer paper 8. A heater 13 and a conveyor belt 14 are disposed at the bottom thereof.

[0008] Next, the operation of the liquid crystal printer 1 will be explained.

[0009] First, when the print start key (not shown) is pressed, the external An image corresponding to the image signal input from is displayed. Next, the light source, halogenated The lamp 103 is turned on, and the light from the halogen lamp 103 passes through the reflector 102 and the condensing lamp. The light is efficiently focused by the lenses 104 and converted into almost parallel light beams, which are passed through the infrared cut filter. The light is irradiated onto the LCD 6 via the filter 105 and the red filter 122R. stationary The microcapsule paper 7 is controlled by the LCD 6 according to the red signal of the image to be recorded. is exposed to the selected light. When the red exposure ends, the red filter 122R turns green. Replaced with color filter 122G, red signal of LCD6 switched to green signal and exposed in the same way. The same goes for blue, and after three exposures The halogen lamp 103 is turned off. In this way, the color is applied to the microcapsule paper 7. A latent image is formed. Next, the microcapsule paper 7 is moved between the take-up roller 16 and the feed roller. The driving force of roller 19 sends it in the direction of pressure rollers 11a and 11b. On the other hand, developer paper 8 is fed one by one by half-moon roller 9, passes through paper feed guide 17, and reaches paper feed roller 10. is sent to pressure rollers 11a and 11b. The exposed surface of microcapsule paper 7 and the microscope The colored paper 8 is pressed by pressure rollers 11a and 11b with the color developer coated surfaces facing each other. , the image is transferred to developer paper 8. Further, the color developing paper 8 is further conveyed by a conveyor belt 14. The color development is promoted by the heat fixing device 12 having a heater 13 while the image is is output.

[Problem that the idea aims to solve] In this way, in the conventional device, a halogen lamp is placed above the LCD 6 as a light source. The lamp 103, reflector 102, and condensing lens 104 are arranged in a straight line, and An image is recorded on the microcapsule paper 7 by irradiating the LCD 106 with light. there was. Therefore, there are restrictions on how and where the light source and optical shutter can be placed, and the equipment is large. There was a problem of becoming

[0011] This invention was made to solve the above-mentioned problems, and it Providing a compact image recording device by increasing the degree of freedom in how and where the shutter is placed It is intended to.

0012

[Means to solve the problem]

To achieve this purpose, the image recording device of this invention has , comprising an optical fiber for transmitting light from the light source.

[0013]

[Effect]

In the image recording device of the present invention having the above configuration, the light from the light source is transmitted through an optical fiber. The light is transmitted to the shutter by the bar. Photosensitive recording media with light transmitted through an optical shutter An image is formed on top.

[0014]

【Example】

Hereinafter, embodiments embodying the present invention will be described with reference to the drawings.

[0015] In this example, the same parts as those in the conventional device are designated by the same reference numerals. A detailed explanation will be omitted.

[0016] The liquid crystal printer 1 of this embodiment will be described with reference to FIGS. 1 and 2. exposure light A halogen lamp 3 is used as a source, and the halogen lamp 3 is connected to a plurality of optical fibers. It is adjacent to the light incident end 4a of the optical fiber bundle 4 formed by bundling fibers. Hello again An infrared cut filter 5 and a color filter are provided between the gen lamp 3 and the light incidence end 4a. A filter unit 22 consisting of 22R, 22G, and 22B is provided. light A light emitting end 4b of the fiber bundle 4 faces the LCD 6. Note that the optical fiber of this example The angle of spread of the irradiated light is 10° or less.

[0018] The light emitted from the halogen lamp 3 is reflected by the reflector 2, and the infrared cutoff The light passes through the filter 5 and the red filter 22R and enters the optical fiber bundle 4 from the incident light end 4a. The light is transmitted through the optical fiber bundle 4 and is emitted from the light emitting end 4b.

[0019] The light emitted from the light emitting end 4b is controlled according to the red signal of the image to be recorded. The light passes through the LCD 6 and is exposed to the microcapsule paper 7. When the red exposure ends The red filter 22R is replaced with the green filter 22G, and the red signal of the LCD 6 is switched to a green signal and exposed in the same way. The same goes for blue, 3 When the second exposure is completed, the halogen lamp 3 is turned off. Thus the microcapsule A color latent image is formed on the paper 7.

[0020] Thereafter, images are output as in the conventional device.

[0021] FIG. 3 shows a modification of the present invention. Reduce the number of optical fibers in the optical fiber bundle 40 The light emitting ends 40b are aligned in a direction perpendicular to the conveyance direction of the microcapsule paper 7. so as to perform exposure while moving above the LCD 6 in the direction of arrow A. This is what I did.

[0022] As is clear from the detailed description above, in the liquid crystal printer 1 of this embodiment, By connecting the halogen lamp 3 and the LCD 6 with optical fiber bundles 4 and 40, , increasing the degree of freedom in the arrangement of the halogen lamp 3 and LCD 6. As a result, the equipment can be made smaller. can be done.

[0023] It should be noted that the present invention is not limited to the embodiments detailed above, and there may be no deviation from the spirit thereof. It is possible to change the range that does not apply.
