DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a thermal recording head used in a thermal recording device.

Conventionally, there have been recording heads of this type as shown in FIGS. 1 and 2.

By the way, in general, the recording time 7e of one recording dot in thermal recording requires a relatively long time of 3 to skin seconds.
When using a printer or facsimile machine, the recording time per line can be shortened by driving the drive leads in parallel. However, since the number of dots required is several hundred to several thousand, the cost of driving all the dots simultaneously is enormous, and for this reason, a time-sequential driving method and a parallel driving method are usually used at the same time. In this case, the recording time per line will further increase to n7e, where n is the number of blocks in time-sequential driving. One way to increase this printing speed is to double the feeding speed of the thermal paper, especially if precision is not required for drawing. For example, there is a method of reducing the line density in the paper feeding direction from the usual 8 lines/side to 4 lines/side and shortening the recording time to 1/2, that is, doubling the speed. However, in a conventional recording head, if the printhead is operated in double high speed mode, for example from 8 lines/side to 4 lines/skin, the interval between each line increases, resulting in a decrease in density and, ultimately, deterioration in image quality.

In order to prevent deterioration, the recording period 7r must be set to 1'2, but shortening 7r shortens the recording time e of one recording head, resulting in a new cause of deterioration: insufficient heat generation. Conventionally, as a method for achieving high-speed recording without causing the above-mentioned deterioration, for example, Samurai Publication No. 47-15152 and Jitoseki No. 52-16934 have been proposed.
As shown in Japanese Patent No. 8, two lines of resistance heating elements are formed.

However, in the heads described in the prior publications, two lines of resistance heating elements are simply formed, which complicates the manufacturing process, and especially in the former head, one electrode serves as a common electrode for all elements.

This invention was made in order to eliminate the drawbacks of the conventional ones as described above, and it is a thermosensitive recording device that allows high-speed recording without causing deterioration, and which does not require much complication in the manufacturing process. The purpose is to provide a

The resistance heating element 2 has a lead electrode 3a and a T between the lead electrodes 3a and the third space.
L is between 30 and 3b5, T3 is 3b between 3a2 and 3b2
L is divided between 3 and 3b2. The thermal head formed in this way is shown in Figures 4 to 7.
To explain in more detail using an enlarged view of the figure, the lead electrodes 3a, ~3an, 3b, ~3bn are made of silver palladium, gold, etc., and are formed on a predetermined band-shaped area on the substrate 1 to which the resistor 2 is to be attached. Formed by printing or baking thick film material. At this time, lead electrodes 3a3, 3 cases, 3a9...3b2, 3b arranged alternately facing each other.
It is preferable that the tips extending into the predetermined regions of No. 5, 30, . . . pass through the predetermined regions and protrude to the other side. Then, the resistor 2 is attached over the entire predetermined area. This resistor 2 is formed by printing or baking a paste such as ruthenium oxide. After forming the resistor 2, use a laser or the like to cut off only the resistor, leaving the electrode, at the axis connecting the slits 6n, and forming the resistor T.
,,T3,T5...T2n-, and T2,T4...T
Separate 2n. Finally, as shown in FIG. 5, a glass overcoat 5 is formed to improve wear resistance. The resistor 2 may be cut by a laser or the like after the glass overcoat 5 is formed. For reference, when a laser or light beam is used, the resistor 5 is much easier to cut than the electrode made of gold etc. in terms of reflectance and heat absorption, and it is easier to cut only the resistor 5. can be done. In the above configuration, the selective heat generation of each heating element T, -Tn is as follows.

In addition, this head allows printing of heating elements in two rows instead of just one horizontal row as in the past, and has a configuration in which opposing electrodes are inserted with slots between the electrodes that are alternately arranged facing each other. As a result, the following characteristics occur. First of all, one of its features is its ability to handle high speeds. In other words, since the print size of the print dots can be doubled by the signal, even in a high-speed print mode in which the number of lines is reduced from 8 lines/side to 4 lines/side, for example, the density does not decrease. In other words, in the case of 8 lines/side printing mode, the external electrodes 3a, 3a2, 3a4, 3a5, 3a
7, 3a8...or 4b,, 4b3, 4b4,

Print using either T2n. On the other hand, in the case of high-speed printing mode of 4 lines/side, the external electrodes 4a, 40,
4a2-4 gives a common signal to 4a4-4 hall. For example, if you turn on 4b2 and give print signals to 4a and 40 at the same time, T and L will generate heat at the same time, and T or T
In the case of only 2, the shape of the printed dot increases, so the density does not decrease. Even in the case of the 8-line/side printing mode, the information on the first line is given to T,, T3,...T2n-, and the information on the next line is given to L, L,...T2n at the same timing. .

In other words, since two lines can be printed at the same time, the speed can be doubled compared to the conventional method. Yet another feature is support for halftone expression using a dot matrix.

Since the four dots of 2, T3 and T4 are independent, it is possible to express multiple levels of halftones as shown in FIG. Another feature is support for multicolor recording.

A method for producing multiple colors involves changing the coloring temperature of thermal paper depending on the color. For example, in FIG. 11, assume that thermal paper is blue colored (dotted line A) at 100 oo and red colored (dotted line B) at 150 or more. Now, the feeding of the thermal paper is synchronized with the stepping motor and is driven upward at a distance d per pulse as shown in FIG. First, heating elements T2, T4, public,...
...Irrespective of the color of blue or red at T2n, both colored dots are energized to generate heat. Next, after the thermal paper is sent a distance d, electricity is applied only to the red colored dots at T,, public, T5, . . . T2n-,. On the other hand, T2,L,t,
At T2n, both the blue and red dots of the next line are energized to generate heat, and this operation is repeated thereafter. The heat generation state of the dots due to this scanning will be explained with reference to FIG. First, at timing A, energization begins in both the red and blue dots, and within the period of the applied pulse, the paper surface temperature exceeds 100 oo and a blue color develops. At the next timing B, a pulse is applied again only to the red colored part, but because the paper surface temperature exceeds 15,000 due to the residual heat of A, this part becomes red. In this way, it is possible to display one color on the thermal paper surface.
Yet another feature is that the connection part of each lead electrode to the external terminal is approximately 3/4 of the arrangement pitch P in the arrangement direction.
Since the wiring density of the connection part of the electrode with the external terminal is reduced without reducing the wiring density of the heating element Tn, the connection with the external terminal is facilitated. Moreover, since the permissible current of the electrode can be increased, a predetermined current can be applied to the heating element Tn in a short time.
It is possible to shorten the heat generation time, that is, the recording time.

Further, FIG. 9 shows a thermal recording head according to another embodiment of the present invention. In this embodiment, the resistance heating element 2 is formed as a band-shaped body that straddles a pair of electrodes facing each other with a slit in between, and the sheet resistance value between the electrodes facing each other through the slit is higher than that in other parts. ing. That is, in this head, the resistive heating element 2 is adhered and formed over the entire predetermined area on the lead electrode on the insulating substrate 1, and after the formation, the external electrodes 4a and 4 are connected to the opposing electrodes through slits.
An overcurrent is applied between 0, 4a2 and 4Q to melt the resistor and provide isolation between the electrodes.
