Abstract

PURPOSE:To enhance printing quality and to perform high speed printing, by differentiating current applying timing, when either one of the recording electrodes adjacent to a recording electrode performing the printing of a certain one pixel performs no printing of a pixel, from that when both of the adjacent recording electrodes perform the printing of the pixel.

In FIG. 5, reference numeral 1 denotes a current-carrying recording sheet, which is composed of a current-carrying layer 2 made of a resistor and an ink layer 3 made of heat-melting ink. Reference numeral 4 denotes a recording head, the tip of which is in contact with the current-carrying layer 2 of the current-carrying recording sheet 1 . At the tip of the recording head 4, a plurality of recording electrodes 5 are arranged in a line, and a common electrode 6 is provided at a position separated from the recording electrodes 5 by a predetermined distance. Further, the recording head 4 is configured to be movable in the direction of the arrow in the figure by a moving means (not shown). A voltage is selectively applied between the recording electrode 5 and the common electrode 6 by a drive circuit (not shown) according to an image signal. 3f configured as above! In the i-electronic recording device, when a voltage is applied to the recording electrode 5, a recording current flows from the recording electrode 5 through the current-carrying layer 2 of the current-carrying recording sheet 1 to the common electrode 6. At this time, since the current is concentrated near the recording electrode 5, heat is generated in this vicinity, and this heat melts the ink in the ink layer 3 of the current-carrying recording sheet 1 and transfers it to a recording paper (not shown).

Problems to be Solved by the Invention However, since the recording electrodes 5 are arranged close to each other in the current-carrying recording device as described above, if all the recording electrodes 5 are driven at the same time, it is difficult to solve the problem. Recording electrodes 50 close to each other
Print quality deteriorates due to interference between the two. In other words, it is a record of one particular energization! When three electrodes are captured, if current is also applied to the recording electrode adjacent to the recording electrode, the current paths are mutually restricted in the current-carrying layer 2 of the current-carrying recording sheet 1, so that the current is not applied to the adjacent recording electrodes. The value of the current flowing through the recording electrode is reduced and the way the current flows in the current-carrying layer 2 is also different compared to the case where this is not performed. Therefore, if only one of the recording electrodes adjacent to one recording electrode is energized, the recording electrodes on both sides of the recording electrode to which one energization is applied are both energized. The shape, size, or density of the printed pixels differs from the case where printing is performed. FIG. 6 shows the shape of the image 7 printed by the recording electrode 5 and the positional relationship between the recording electrode 5 and the common electrode 6 as well as the recording head 4.
This is shown as a diagram viewed from the side.From this, when electricity is applied to only one of the recording electrodes 5 adjacent to a certain recording electrode 5, the case where electricity is applied to both adjacent recording electrodes 5 is higher than when electricity is applied to both adjacent recording electrodes 5. As large pixels are printed, the shape of the pixels becomes distorted, and the pixels bulge in the opposite direction to the common electrode 6 in the vicinity of the recording electrode 5. Therefore, at the ends of consecutive black pixels in the vertical direction, the pixels become large and bulge, and a distorted image with a whisker-like shape is printed. This deteriorates print quality. This phenomenon is caused by the fact that when adjacent recording electrodes are energized at the same time, each recording electrode has the same potential, so not much current flows in the current-carrying layer between these recording electrodes. Regarding the recording electrode that prints the pixels at the end of the recording electrode, the current flow is not inhibited on the side where the adjacent recording electrode does not print, so the current spreads and flows, and the value of the current flowing through this recording electrode becomes large. As a result, the value of the current flowing through the recording electrodes changes depending on whether or not the adjacent recording electrodes are energized at the same time, and the way the current flows also changes.
The size and shape of pixels also change.

れる画像の縦線の直線性が悪くなるとともに印字の速度
が遅くなるという欠点を持っている。In addition, in order to eliminate the influence of interference between adjacent recording electrodes, a method has been proposed in which time-division driving is performed so that every few recording electrodes are energized at the same time. Since the timings of the images are different, the linearity of the vertical lines of the printed image deteriorates and the printing speed becomes slow.

素の位置が異なり印字品質が悪いものである。Also, while the above conventional example uses a constant voltage method in which the voltage applied to each recording electrode is constant, a constant current method in which the current value applied to each recording electrode is constant may also be considered, but in this case, However, since the path of the current flowing through the current-carrying layer itself does not change, the pixel printing position when only one of the adjacent electrodes prints the pixel is the same as when both adjacent electrodes print the pixel. Printed at a position opposite to the common electrode. Therefore, the pixel positions at the ends of consecutive black pixels in the vertical direction are different from those at the center of consecutive black pixels, resulting in poor print quality.

ものである。Function The present invention is a recording method for printing a certain pixel using the above-described configuration. When one of the recording electrodes adjacent to the ilt pole does not print pixels, the current path is different from when both adjacent recording electrodes print pixels, so the position of the printed pixel is different. However, by varying the timing of current application, the printing position of the pixel is corrected, and printing with good quality is performed.

In FIG. 1, when only one of the recording electrodes 5 on both sides of a recording electrode 5 that prints one pixel prints a pixel, and when both of the recording electrodes 5 on both sides print a pixel, The application is started after a delay of time T1. Also,
The applied pulse width is set to be the same regardless of the printing state of the recording electrodes 5 on both sides. That is, in the example shown in FIG. 1, white, black, black, black, black, and white data are applied to the recording electrodes 5a to 5f in this order, and the recording electrodes 5b and 5
The recording electrodes 5C15d and 5e are made to print black pixels, but at this time, the recording electrodes 5C15d are made to apply pulses at normal timing in order to cause the recording electrodes on both sides to also print pixels, and the recording electrodes 5B, 5E are made to print black pixels. 5e, in order to cause printing to be performed only on one of the recording electrodes on both sides, the pulse application is started with a time delay of T1 compared to when printing is performed on both adjacent recording electrodes. Further, at this time, the recording electrodes 5b and 5e print the pixels at the ends of the black pixels that are continuous in the vertical direction, and in such a case, the time is delayed and a pulse is applied.

印字品質を向上できるものである。By the above-described operation, conventionally, when pixel printing is performed on only one of the recording electrodes adjacent to the recording electrode 5 that prints one pixel, the adjacent recording electrode 5 prints on the adjacent recording electrode 5.
The current flowing through the recording electrode 5 was larger than when pixel printing was performed on both of the three electrodes, and the applied energy was larger, resulting in larger pixels being printed and the printing position of the pixel being shifted. On the other hand, according to the present invention,
When printing is performed by passing a constant current through each recording electrode, and when pixel printing is performed only on one side of the recording electrode adjacent to the recording electrode 5 that prints one pixel, both of the adjacent recording electrodes When pixel printing is performed in Print quality can be improved by averaging the pixels.

できるものである。In other words, conventionally, when pixel printing is performed on only one of the recording electrodes adjacent to recording electrode 5 that performs pixel printing, compared to when pixel printing is performed on both adjacent recording electrodes. Pixels that are printed are misaligned in the opposite direction to the common electrode, and as a result, pixels protrude rearward in the direction of movement of the recording head 4 at the ends of black pixels that are printed continuously in the vertical direction. However, according to the present invention, when pixel printing is performed on only one of the recording electrodes adjacent to the recording electrode 5 that prints one pixel, the image is printed on both of the adjacent recording electrodes. The pulse application is started with a time delay compared to when pixel printing is performed, and as the RAD 4 moves to the recording area during the delayed pulse application time, the pulse is applied from this moved position. Since the pixel is applied, the printed pixel is printed at a position advanced in the traveling direction, and the shape of the pixel can be corrected without protruding backward in the traveling direction as in the conventional case.

が得られる。In addition, in the above embodiment, since the common electrode 6 is moved in advance of the recording electrode 5, only one of the recording electrodes adjacent to the recording electrode 5 that performs pixel printing When pixel printing is performed, the application of current is started at a later time than when pixel printing is performed on both adjacent recording electrodes, but the recording electrode 5 is placed in advance of the common electrode 6. When the pixel is printed on only one of the adjacent recording electrodes, the current application ends earlier than when the pixel is printed on both adjacent recording electrodes. A similar effect can be obtained by doing this.

させることができる。Furthermore, when pixels are not printed on both of the adjacent recording electrodes for a certain recording electrode 5 that performs pixel printing, the number of pixels is still smaller than when pixels are printed on both adjacent recording electrodes. Since the position is shifted to the side opposite to the common electrode, it is possible to correct the printing position and improve printing quality by shifting the timing of current application in the same manner as described above.

The application may be started with a delay. For example, Fig. 4 is a diagram showing a printing pattern, and the arrow in the diagram indicates the direction of movement of the recording head, but the current application is delayed and started only when printing the pixels shown in 1) in the diagram. You can do it like this.

記録装置を提供することができるものである。Effects of the Invention As described above, the current-carrying recording device of the present invention causes a constant current to flow through each recording electrode to perform printing, and at the same time, among the recording electrodes adjacent to the recording electrode that performs one pixel printing, When pixels are printed on only one side, the timing of current application is shifted from when pixels are printed on both adjacent recording electrodes, and for this reason, the printed pixels are averaged and This corrects the positional deviation of printed pixels to enable printing with good quality. In addition, since there is no need for hour-minute-j driving, high-speed printing is possible, and printing with good pixel alignment is possible without misalignment of printed pixels due to differences in energization times. in this way,
According to the present invention, it is possible to provide an energization recording device with good print quality (capable of high-speed printing).
