大きな問題点が発生する。In this type of recording, line recording is possible when a large number of recording electrodes are provided so that one recording electrode corresponds to one dot, and a high-speed hard copy device can be constructed. However, if the dont density is 8 chems, then the number of recording electrodes will be 1728 for A4 size, for example, and the same number of drivers and connection lines will be required at the same time, which will increase the cost and make mounting difficult. A major problem arises.

紙上では全画面が黒になる。FIG. 6 is a diagram depicting the arrangement and connection of the recording electrode 6 that applies signals and the liquid ink permeable electrode 9, and shows that the number of recording electrodes is 512, 64<<, and the number of ink permeable electrodes is 8.
This is the case. 5-101.5-102.5-108

5-64 shows signal application terminals to recording electrodes arranged every 64 times. A waveform diagram of the signal to be applied is shown in FIG. In Figure 6, image signals divided into dots are applied to the recording electrodes simultaneously, a selection signal is applied to the ink-permeable electrodes, and odd-numbered recording electrodes (32) are applied during the period. This is a case in which recording is performed by applying image signals to even-numbered recording electrodes (32 trees) during period T2, and these signals turn the entire screen black on the recording paper.

とが出来る。The reason why the time for applying the voltage to the recording electrodes is divided into odd-numbered and even-numbered periods is to utilize the focusing of ink due to electroosmosis on the dielectric substrate 1. Tr is the period of one line. In the figure, 6-1°6-3. ...6-63
is the input signal waveform to the terminal 5-1.5-3゜5-63 in Fig. 5, and 6-2.6-4゜6-64 is the input signal waveform to the terminal 6-2 in Fig. 5.

One ink-permeable electrode is selected using the selection signal No. 108, and image signals corresponding to each time are simultaneously applied to the odd-numbered recording electrodes, and then simultaneously applied to the even-numbered recording electrodes, and this operation is performed in sequence. By repeating this, you can record one line.

である。In Figures 5 and 6, 64 electrodes are combined, that is, one liquid ink permeable electrode corresponds to an even number of recording electrodes, but one liquid ink permeable electrode corresponds to an odd number of recording electrodes. Consider the case where there is. FIG. 7 depicts a cross section of the recording head and the connections of the recording electrodes.
1, 2, 5°6, and 9 are the same as shown in FIG.

番目の記録電極に交互に信号を印加することによって正
常でかつきれいな配録画像を得ることが出来る。In this way, when there is one liquid ink permeable electrode for an odd number of recording electrodes, for example, if 7-101 is selected and image signals are input to 7-1, 7-3, and 7-5, In the figure, an image signal is also present in the electrode to the right of 7-5, so that the electroosmotic property on the dielectric substrate 1 becomes weaker and the ink focusing on the electrode 7-5 becomes worse. This is undesirable because it reduces recording density and furthermore reduces resolution. In order to avoid this, liquid ink permeable electrodes should be arranged corresponding to even numbered recording electrodes; in this case, signals should be applied alternately to odd numbered recording electrodes and even numbered recording electrodes. By doing this, a normal and clear recorded image can be obtained.

。Next, consider the electrode gap between the divided liquid ink permeable electrodes. In FIG. 8, 1, 2, 5.6 and 9 are the same as shown in FIG. 3, and terminals 8-101 and 8-1
02 is a signal input terminal to the liquid ink permeable electrode, terminal 8
-1, 8-2, and 8-3 are signal input terminals to the recording electrodes. Now, assume that the liquid ink-permeable electrode 9 is placed up to the point indicated by the dotted line, and the terminal 8-101 is selected.
- Consider a case where an on signal of an image signal is applied to the terminal 8-1, an off signal is applied to the terminal 8-2, and an on signal of the image signal is applied to the terminal 8-3. At this time, even though 8-102 is not selected, ink may come out to the recording electrode 8-3. This is because there is a flow of ink as shown by the arrow in the figure.The pitch of the recording electrodes 5 is usually 8 lines/mm, or 12 lines, in order to obtain a high-resolution image.
Considering that it is 5 μm, it is easy to imagine ink leakage.To solve this problem, it is sufficient to have a recording electrode that always gives an off signal in the electrode gap of the liquid ink permeable electrode. That is, it is preferable to arrange the liquid ink permeable electrodes as shown by the solid line in FIG. 8, and it is sufficient that two or more recording electrodes are present in the gap between the electrodes. Furthermore, if there are four or more recording electrodes, there will be two recording electrodes to which off signals are applied, making it impossible to obtain desired recording.

10-1 to 10-64 are terminals 9-1 to 9-6 in FIG.
It is an image signal applied to 4, and 10-101 to 10-1
17 are terminals 9-101 to 9-117 in FIG. 9, respectively.
This is the selection signal applied to the Describing the operation in FIGS. 9 and 10, 9-1 to 9-32 in period T11
An image signal is applied to the odd-numbered recording electrodes in the period T
In period T12, image signals are applied to even-numbered recording electrodes from 9-1 to 9-32, and in period T13, image signals are applied to even-numbered recording electrodes from 9-33 to 9-6.
4, and in period T14, 9-33~
An image signal is applied to an even number among 9-64. That is, the 64-diameter recording electrode is temporally divided into two,
Furthermore, time-division driving is performed in which the drive is divided into odd and even numbers.
