BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image forming method in which a photosensitive recording medium is exposed to light using a light source and an LCD panel as a light shutter.

0002

[Prior Art] Conventionally, in an image forming apparatus using this type of image forming apparatus, when it was desired to display a composite image of multiple images on a single output image, the images were composited on an LCD panel. .

0003

[Problems to be Solved by the Invention] However, the above method requires a lot of effort.

The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide an image output method that can easily output a composite image.

[0005]

[Means and effects for solving the problem] In order to achieve this object, in the image forming method of the present invention, the image displayed on the LCD panel is changed multiple times, and exposure is performed each time the image is changed. As a result, a composite image of a plurality of images is recorded on the photosensitive recording medium.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment embodying the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic diagram of a liquid crystal printer to which the microcapsule paper of the present invention is applied.

This liquid crystal printer 1 uses a photosensitive recording medium consisting of microcapsule paper 7 and color developer paper 8, which are photosensitive pressure sensitive papers.

Microcapsules are coated on the surface of the support of the microcapsule paper 7 used in this example, and the microcapsules contain a dye precursor that reacts with a color developer. There is. A color developer is coated on the surface of the support of the color developer paper 8 and develops color by reacting with a dye precursor, but the details are described in U.S. Pat. No. 4,399,209, etc., and are omitted here. do.

A halogen lamp 3 is used as an exposure light source, and a reflector 2 is placed above it. Further, a condenser lens 4 is arranged below the halogen lamp 3, and an infrared cut filter 5 is further arranged below it. Below the infrared cut filter 5, a filter unit 22 consisting of color filters 22R, 22G, and 22B and an LCD 6 are arranged.

The light-shielding cartridge 18 contains unexposed microcapsule paper 7 wound around the cartridge shaft 15. A feed roller 19 is disposed on the right side of the cartridge 18, and the feed roller 19 transports the microcapsule paper 7 in the direction of the LCD 6. The microcapsule paper 7 is exposed to light while stationary below the LCD 6, and a latent image is formed. Ru. Further, the microcapsule paper 7 passes between a pair of pressure rollers 11a and 11b, and is wound around a winding shaft 16.

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

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

First, when a print start key (not shown) is pressed, an image corresponding to an image signal input from the outside is displayed on the LCD 6. Next, the halogen lamp 3 that is the light source is turned on, and the light from the halogen lamp 3 is efficiently condensed by the reflector 2 and the condensing lens 4, converted into almost parallel light beams, and transmitted through the infrared cut filter 5 and the red filter 22R. and illuminates the LCD 6. The stationary microcapsule paper 7 is exposed to light selected by the LCD 6, which is controlled according to the red signal of the image to be recorded. When the red exposure is completed, the red filter 22R is replaced with the green filter 22G, the red signal of the LCD 6 is switched to a green signal, and exposure is performed in the same manner. The same goes for blue, and after three exposures, the halogen lamp 3
is turned off. In this way, a color latent image is formed on the microcapsule paper 7.

At this point, during normal image output, the microcapsule paper 7 is sent in the direction of the pressure rollers 11a and 11b by the driving force of the take-up roller 16 and the feed roller 19. On the other hand, the developer paper 8 is fed one by one by a half-moon roller 9, passes through a paper feed guide 17, and is sent by a paper feed roller 10 to pressure rollers 11a, b. The exposed surface of the microcapsule paper 7 and the developer-coated surface of the color developer paper 8 are pressed by pressure rollers 11a and 11b in a state where they face each other, and the image is transferred to the color developer paper 8. Further, color development of the color developing paper 8 is promoted by a heat fixing device 12 having a heater 13 while being further conveyed by a conveyor belt 14, and outputted as an image.

Next, a case will be described in which a composite image of a plurality of images is formed on the same screen.

At the point when one color image is formed on the microcapsule paper 7, another image is controlled to be displayed on the LCD 6, and as in the above example, three color filters are used to display the other image. The latent image of the image is transferred to microcapsule paper 7.
Form on top. Therefore, a latent image of a composite image of the two images is formed on the microcapsule paper 7. After exposure, the image is subjected to pressure development and heat fixing as described above, and then output. If you want to output a composite image of three or more images, you can repeat similar exposures.

As is clear from the above detailed description, the liquid crystal printer 1 of this embodiment changes the image displayed on the LCD 6 multiple times and performs exposure each time the image changes, thereby making it possible to Since a composite image of a plurality of images is recorded on the capsule paper 7, the composite image can be easily output.

It should be noted that the present invention is not limited to the embodiments described in detail above, and modifications can be made without departing from the spirit thereof.

[0020]

Effects of the Invention As is clear from the above detailed description, in the image forming method of the present invention, the image displayed on the LCD panel is changed multiple times, and exposure is performed each time the image is changed. Since a composite image of a plurality of images is recorded on a photosensitive recording medium, a composite image can be easily output.
