FIG. 2 shows a color thermosensitive recording material used in the present invention. In the color thermosensitive recording material 10, a cyan thermosensitive coloring layer 12, a magenta thermosensitive coloring layer 13, a yellow thermosensitive coloring layer 14, and a protective layer 15 are sequentially provided on a support 11. As the support 11, opaque coated paper or plastic film is used.
When forming a P sheet, a transparent plastic film is used.

The cyan thermosensitive coloring layer 12 contains an electron-donating dye precursor and an electron-accepting compound as main components, and develops cyan when heated. Magenta thermosensitive coloring layer 1
No. 3 contains a diazonium salt compound having a maximum absorption wavelength of about 365 nm and a coupler which reacts with the diazonium salt compound and develops magenta. When the magenta thermosensitive coloring layer 13 is irradiated with ultraviolet light having a wavelength of about 365 nm, the diazonium salt compound undergoes photodecomposition in accordance with the amount of exposure to the ultraviolet light and loses its coloring ability. The yellow thermosensitive coloring layer 14 contains a diazonium salt compound having a maximum absorption wavelength of about 420 nm and a coupler which reacts with the diazonium salt compound to develop yellow color. The yellow thermosensitive coloring layer 14 has almost 4
Irradiation with near-ultraviolet light (blue-violet light) in the vicinity of 20 nm loses the color-forming ability. The specific structure of each of the thermosensitive coloring layers 12 to 14 is described in detail in Japanese Patent Application Laid-Open No. 3-288688 filed by the present applicant.

FIG. 3 shows the coloring characteristics of the thermosensitive coloring layers 12-14. The thermal energy on the horizontal axis represents the thermal energy generated by the heating element of the thermal head, and the coloring thermal energy of the yellow thermosensitive coloring layer 14 is the lowest, and therefore, the thermal recording sensitivity is the highest. On the other hand, the cyan thermosensitive coloring layer 12 has the highest coloring heat energy and therefore the lowest thermal recording sensitivity. The main cause of the difference in the coloring heat energy is that the cyan coloring layer 12 must be heated via the yellow coloring layer 14 and the magenta coloring layer 13. In a normal storage state, since the heat energy does not exceed the coloring heat energy of the cyan thermosensitive coloring layer 12, no light fixing property is given thereto. If necessary, a light fixing property may be imparted by using a diazonium salt compound and a coupler.

FIGS. 1 and 4 show an example of a color multi-channel recorder embodying the present invention. The color thermosensitive recording material 10 is wound up and stored in a roll form, and is sent to a platen roller 22 by a pair of conveying rollers 20 and 21. The conveying roller pair 20, 21 is a motor 23.
Is rotated by The rotation of the motor 23 is controlled by a recorder main body 25 via a driver 24.

Above the platen roller 22, there is provided a thermal head 26 in which a number of heating elements are arranged in a line. Each heating element of the thermal head 26 is driven by a head driving unit 27. The head drive unit 27 drives each heating element based on the waveform data from the recorder main body 25 to control the temperature to an arbitrary thermosensitive coloring temperature. At this time, since each heating element is controlled at a different heat-sensitive coloring temperature for each channel and the color thermosensitive recording material 10 is sent in synchronism, as shown in FIG. Waveform data 28a, 28b,
.. Are thermally recorded.

A yellow fixing lamp 30 and a magenta fixing lamp 31 are provided upstream of the thermal head 26, and a yellow fixing lamp 32 and a magenta fixing lamp 33 are similarly provided downstream thereof.

The yellow fixing lamps 30 and 32 are almost 4
It is composed of a rod-shaped ultraviolet lamp having an emission peak at 20 nm, and the lamp emits near-ultraviolet light (blue-violet light) at about 420 nm, thereby eliminating the coloring ability of the yellow thermosensitive coloring layer. The magenta fixing lamps 31 and 33 are constituted by rod-shaped ultraviolet lamps having an emission peak at approximately 365 nm, and the irradiation of ultraviolet light from these lamps eliminates the coloring ability of the magenta thermosensitive coloring layer.

[0014]

[Table 1]

Table 1 shows driving examples of the fixing lamps 30 to 33 and the thermal head 26 when recording the waveform data of each channel by color. Each symbol Y represents yellow, R represents red, BL represents black, M represents magenta, B represents blue, and C represents cyan. When recording the waveform data in yellow, the lamp 3 on the upstream side of the thermal head 26 is used.
Turn off both 0 and 31. Further, the heat generating element has a small heat value corresponding to heat energy for heat-sensitive coloring of the yellow heat-sensitive coloring layer. In addition, by setting the heating value of the heating element to a medium level in the driving state of the lamp, the thermosensitive coloring layers of yellow and magenta can be simultaneously thermosensitively colored. Is done. In the driving state of the lamp,
By increasing the amount of heat generated by the heating element, yellow,
The magenta and cyan thermosensitive coloring layers can be colored simultaneously, and the mixed colors record waveform data in black.

The amount of heat generated by the heating element at this time is changed within the color temperature range of the magenta heat-sensitive coloring layer 13, thereby changing the color density of magenta and changing the degree of color mixing with yellow. Different colors can be recorded. Similarly, by changing the amount of heat generated by the heating element within the color temperature range of the cyan thermosensitive coloring layer 12, the color density of cyan is changed to change the degree of color mixture with yellow and magenta. It can be changed to other colors.

When recording in magenta, the heating element is set to a magenta color temperature range in a state where the yellow fixing lamp 30 on the upstream side is turned on and the coloring ability of the yellow thermosensitive coloring layer 14 is lost. When recording in cyan, the heating element is set to cyan while the yellow and magenta thermosensitive coloring layers 14 and 13 lose their coloring ability by turning on both the yellow fixing lamp 30 and the magenta fixing lamp 31 on the upstream side. Set the color temperature range. In addition,
If it is desired to record the waveform data of the other channels in yellow, red, or the like when the upstream lamps 30 and 31 are turned on, light is shielded by covering these recording areas using a known light shielding device (not shown). By doing so, the waveform data can be thermally recorded in yellow or red in these areas. Note that a lamp may be provided for each recording area instead of the light shielding device.

FIG. 5 shows an arrangement in which a second thermal head 34 is arranged on the downstream side of the magenta fixing lamp 33, which is the most downstream of the color multi-channel recorder. Then, the first thermal head 26 controls the yellow thermosensitive coloring layer 1.
As shown in Table 2, a combination of three colors of yellow, cyan, and green obtained by mixing the yellow and cyan is obtained by causing the second thermal head 34 to develop the color and the second thermal head 34. . Further, the first thermal head 26 uses the thermosensitive coloring layer 1 of yellow and magenta.
The combination of three colors of red, cyan and black can be obtained by coloring the cyan thermosensitive coloring layer 12 with the second thermal head 34 while coloring the colors 4 and 13. Further, by turning on the yellow fixing lamp 30 on the upstream side and eliminating the coloring ability of the yellow thermosensitive coloring layer 14, a combination of three colors of magenta, cyan and black can be obtained.

[Table 2]

FIG. 6 shows a full-color multi-channel recorder. Three thermal heads 50, 51, and 52 are sequentially provided in the transport direction, and a yellow fixing lamp 53 and a magenta fixing lamp 54 are provided between these heads. In this case, the yellow thermal coloring layer is optically fixed by the yellow fixing lamp 53 after the yellow image is thermally recorded on the yellow coloring layer by the first thermal head 50. Next, after a magenta image is thermally recorded on the magenta thermosensitive coloring layer by the second thermal head 51, the magenta thermosensitive coloring layer is optically fixed by the magenta fixing lamp. Thus, in addition to yellow, magenta, and cyan, waveform data of each channel can be thermally recorded in other desired colors by a combination of these. In addition, by changing the heat generation energy of the thermal head, it is possible to easily change the color in the same channel even in the same channel.

Because multiple waveform data are thermally recorded , each color data can be changed easily without using an ink ribbon or pen.
Data can be recorded. In addition, the configuration is simplified without using a pen or a driving mechanism thereof. Furthermore, since a pen is not used, no clogging of ink occurs and maintenance is simplified.

In addition, the optical fixing device is selectively activated before thermal recording.
Because it was illuminated, the configuration was simplified and the types of colors that could be used were increased.
Can be Further, by using two thermal heads, the types of colors that can be used can be further increased. Ma
In addition , by using three thermal heads, waveform data can be recorded in an arbitrary color. When a plurality of thermal heads are used, recording of a plurality of different colors can be performed on the same channel.
