Abstract

PURPOSE:To print out hard copies readily in a short time in spite of monochrome or multicolor and to make a system compact by recording information on an image from a liquid crystal panel directly onto a photosensitive recording medium. CONSTITUTION:An image forming device 1 includes the liquid crystal panel 2, a light source 3, an image/data processing circuit 4, and a control circuit 5 which converts a signal from the image/data processing circuit into a signal so as to drive the liquid crystal panel 2, etc. An image recording device 7 is formed of the photosensitive recording machine 8, a press roller 9, and a non- contact heater 10, etc. A sheet which is uniformly painted with oxidizer and a microcapsule including a coloring agent is used as the photosensitive recording medium 8. When the microcapsule is irradiated with beams, only the part solidifies and a shell of a remaining part which is not irradiated with beams is collapsed by a pressuring unit, and the said remaining part reacts with oxidizer, and colors by heating. Thus, hard copies of high image quality can be outputted in a short time.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a hard copy device that copies images by directly recording image information from a liquid crystal panel onto a photosensitive recording medium.

[Conventional technology]

The conventional method of hard copying has been to convert soft copies into electrical signals and indirectly obtain various hard copies. The printer methods include a wire dot method, a thermal method, an inkjet method, and an electrophotographic method. Further, as a method for directly making a hard copy from a soft copy, there is a silver halide photography method. This is a method in which the soft copy surface is directly photographed with a camera and printed on photographic paper.

[Problem to be solved by the invention]

However, conventional indirect methods have problems such as the printing system is extremely large, the ink takes a relatively long time to print, and depending on the method, it is difficult to obtain high-quality full-color prints. . Although high-quality prints can be obtained using the Zarani silver halide photography method,
The problem is that running costs are high.

The objects of the present invention are: - To easily print out whether it is monochrome or full color, to make the system very compact, and to print out in a short time.

[Means to solve the problem]

The hard copy device according to the present invention is characterized in that image information from a liquid crystal panel is directly recorded on a photosensitive recording medium.

〔Example〕

FIG. 1 shows the basic configuration of the present invention. 1 is an image forming device, and a liquid crystal panel 2. Light source 5. Image/data processing circuit 42 includes a control circuit 5 and the like that converts signals from the image/data processing circuit into signals for driving the liquid crystal panel 2. 7 is le
A optical recording medium 8. Pressure roller9. This is an image recording device consisting of a non-contact heater 10 and the like. The photosensitive recording medium used is paper on which, when oxidized, a layer of colorant-containing microcub cells is uniformly coated. Microcapsules are
When irradiated with light, only that part of the capsule solidifies, and the outer shell of the remaining part that is not irradiated with light is destroyed by a pressure vessel, reacts with the saponifying agent, and develops color by heating.

FIG. 2 shows another embodiment of the present invention, and reference numeral 1 designates an image forming apparatus similar to the embodiment shown in FIG.

26 is a photosensitive recording medium 27. Pressure roller 28. Non-contact heater 29. This is an image recording device consisting of transfer recording paper 50 and the like. The photosensitive recording medium is basically the same as that of the embodiment shown in FIG. 1, except that the coloring agent is used to develop color on another transfer recording paper.

As the transfer recording paper, when using microcapsules similar to the embodiment shown in FIG. 1, plain paper coated with an oxidizing agent is used. Further, when the microcapsules contain a self-coloring colorant, plain paper can be used as the transfer recording paper.

The image recording apparatus in the embodiment shown in FIGS. 1 and 2 can be easily removed from the image forming apparatus. Furthermore, the hard copy output time was about 2 seconds, and the image quality was good.

〔Effect of the invention〕

As described above, according to the present invention, a high-quality hard copy can be output in a short time by directly recording image information displayed on a liquid crystal panel onto a photosensitive recording medium.

Further, according to the present invention, the mechanism is extremely simple, and an output interface to a printer is not required at all, making it possible to provide a low-cost hard copy device.

In the embodiment of the present invention, if the image information to the liquid crystal panel is in color, it is clear that a color hard copy can be used.
