ター像を転写する技術が開示されている。Various types of thermal image recording techniques using such thermal recording heads have been proposed. For example, in Japanese Patent Application Laid-Open No. 54-33117, a dot-like perforation image is formed on a sheet made only of a stretched thermoplastic synthetic resin film using a printing device having a dot-like heating element, and the perforation of the sheet is A method has been proposed in which a recording cylinder is formed by allowing ink to pass through an image area. Furthermore, in JP-A-56-371.91, a heat-sensitive transfer ink layer of hectograph carbon paper is placed in contact with the lower surface of a master image-forming substrate, and a heat-sensitive transfer ink layer is placed on the upper surface of the master image-forming substrate. Techniques have been disclosed for transferring a master image from a thermal transfer ink layer to the lower surface of a master imaging substrate by selectively applying heat from a recording head.

Therefore, it is an object of the present invention to provide a thermal image recording apparatus that is capable of recording not only a mirror image necessary for such plate-making technology but also a normal image.

The thermal image recording apparatus is characterized in that the recording medium transport means is reversible so that a normal image or a mirror image can be recorded on the recording medium.
本発明の感熱画像記録装置の実施例を第1図に示す。 An embodiment of the thermal image recording apparatus of the present invention is shown in FIG.

7.8が矢印の方向に回転可能に設けられている。Referring to FIG. 1, a recording medium 1 is passed between a thermal recording head 2 and a pressure roll 4 in close contact with a heating element 3 of the thermal recording head 2. As shown in FIG. This pressure roll 4 is attached so as to be rotatable in two directions as shown by the arrows, and functions to convey the recording medium 1 and press the recording medium 1 against the heating element 3 of the thermal recording head 2. Furthermore, a conveyance roller 5.6 and a counter roller 7.8 are provided on both sides of the thermal recording pad 2 so as to be rotatable in the direction of the arrow.

The rotation of the motor 10 is transmitted to the counter roller 7.8. Note that the motor 10 is a reversible motor, and its rotation direction can be switched between a plate-making mode and a normal recording mode.

As a result, a mirror image is formed on the perforated master 11. On the other hand, in the conventional recording mode 5-, a conventional thermoplastic material (not shown) is used as the recording medium 1, and the pressure roll 4 is rotated in the direction opposite to the direction indicated by the arrow in FIG. As a result, a normal image is formed on the recording medium 1. Note that if the printing conditions are different between the plate making mode and the normal recording mode, it is desirable to switch the printing conditions at the same time as switching the rotational direction of the motor.

The perforated master 11 is made by laminating a biaxially stretched film 13 on one side of a porous base material 12. As the porous base material 12, materials whose main raw materials are natural fibers such as Manila hemp, kozo, and mitsumata, synthetic fibers such as Tetoron, vinylon, and acrylic, and semi-synthetic fibers such as rayon can be used. Other base materials that can be used include woven fibers of nylon, polyester, polypropylene, Tetron, etc. having a thickness of about 20 to 70 μm. The biaxially stretched film 13 is preferably a polyester film with a thickness of 1 to 5 μm.

As the adhesive, adhesives made of saturated polyester resin, acrylic resin, polyvinyl resin, polystyrene resin, etc. can be used. The adhesive is used by dissolving the solid content of 0.5 to 2.0 g/rrr in an appropriate amount of solvent after drying.

The film is passed between the heat recording pad 2 and the pressure roll 4 so that the film surface is in close contact with the heating element array 13. The pressure roll 4 presses the perforated master 11 against the thermal recording head 2 and moves the perforated master 11 in a predetermined direction (sub-scanning direction) by rotating in the direction of the arrow.

This is a recording element in which a large number of heating elements 3 are arranged in a straight line in the main scanning direction), and is driven by a drive signal supplied from a drive circuit 14 of a thermal recording head. That is, RIS
When an image signal created by reading an original (a raster imprint scanner) or an output signal from a word processor is supplied to the thermal recording head drive circuit 14, a drive signal is generated, and the heating element 3 is selected according to the image information. is energized and generates heat. When the heating element 3 generates heat, a corresponding portion of the biaxially stretched film 13 on the surface of the perforated master 11 is heated. As a result, the two-wheel stretched film is heat-shrinked, perforated in a mirror image, and plate-made.

より記録を行なった。First, in the plate-making mode, a biaxially stretched polyethylene terephthalate film of about 3 μm was pasted on a base made of thin paper, and a perforated hole was attached to the heat generating element part of the thermal recording head, which had a heat generating element formed in a straight line at 8 dots/n. The perforated master was brought into close contact with the film surface of the perforated master, and the perforated master was moved in a direction such that a mirror image was formed on the film surface, thereby forming a perforated image. The printing condition of the thermal recording head is that the applied voltage is 25V.
, the application time was 2111 seconds. By printing the thus perforated master using a mimeograph machine in the usual manner, a clear, normal printed image was obtained. Next, in the normal recording mode, recording was performed by using thermal recording paper instead of the above-mentioned perforated master, bringing the thermal recording layer into close contact with the heating element part, and moving the thermal recording paper in the opposite direction to the plate-making mode. .

Therefore, compared to providing separate devices for both of these modes, it is not only cost-effective but also reduces the space required.
