回路8に接続する構造を提案している。Here, Japanese Patent Publication No. 57-38899 discloses that the recording electrode 5 is constituted by the tip of a conductive wire buttern (lead) formed on a flexible printed circuit board, and that the flexible printed circuit board is It is glued along the outer circumferential surface of the hollow body 1 so as not to interfere with transportation, and the ends of the same circuit board opposite to the recording electrode 6 are taken out to both sides of the hollow body 1 and connected to the electronic circuit 8 with connectors. We are proposing a structure.
しかし、このような構造では、次のような欠点を生じて
いた。However, such a structure has the following drawbacks.
(イ)ファクシミリ装置等における記録装置では、一般
に、記録電極6の密度(画素密度)は8本/順、または
それ以上必要になるが、可撓性印刷回路板に形成し得る
導線パターンの密度は、基板の機械的強度が小さいこと
、基板の吸湿性が大きいこと、基板とパターンとの密着
性が悪いこと等から、通常、3〜6本/陥程度であり、
それ以上の密度を得ることは、歩留まり関係上困難であ
る。(b) In a recording device such as a facsimile machine, the density of recording electrodes 6 (pixel density) is generally required to be 8 lines/order or more, but the density of the conductor pattern that can be formed on a flexible printed circuit board is Usually, there are about 3 to 6 holes/depression due to the low mechanical strength of the substrate, the high moisture absorption of the substrate, and the poor adhesion between the substrate and the pattern.
Obtaining a higher density is difficult in terms of yield.
(ロ) しかも、1枚の可撓性印刷回路板に形成する導
線パターンの数を多くするほど、一層歩留りが悪くなる
ので、1枚の可撓性印刷回路板のみでは、ファクシミリ
装置等において必要となる数の記録電極を得ることがで
きず、多数枚の可撓性印刷回路板を継ぎ合わせる必要が
ある。(b) Moreover, the larger the number of conductor patterns formed on one flexible printed circuit board, the worse the yield becomes. It is not possible to obtain recording electrodes in the number of recording electrodes, and it is necessary to stitch together a large number of flexible printed circuit boards.

常な困難が伴い、コスト高を招く。However, it is difficult to join together a large number of flexible printed circuit boards so that the ends of their conductor patterns are aligned in a straight line.
Furthermore, it is very difficult to prevent the pitch between the conductor patterns from becoming uneven at the joints between the flexible printed circuits, leading to high costs.

この電子回路8にまで可撓性印刷回路板を延長してその
両者を接続しているので、装置が大型化するとともに、
可撓性印刷回路板の延長部の取り扱いが面倒となる。(c) Since the entire electronic circuit 8 is provided apart from the hollow body 1, and the flexible printed circuit board is extended to the electronic circuit 8 to connect the two, the device becomes larger and
Handling of the extensions of the flexible printed circuit board becomes cumbersome.

Furthermore, the lower end of the recording electrode pattern 20 of the recording head 18 is opposed to the back electrode 2 with a gap therebetween. 29
is a recording medium such as electrostatic recording paper or plain paper, and is conveyed in the direction of arrow B between the lower end of the recording electrode pattern 20 and the back electrode 28 by a recording medium supply means such as a paper feed roller (not shown). .
次に、本装置の動作を説明する。Next, the operation of this device will be explained.

を経て、記録電極パターン20の下端部に至る。When the magnet roll 12 is rotated by the magnet drive device, the magnetic field by the magnet roll 12 also rotates, and this rotating magnetic field pulls the toner 14 in the flopper 13 onto the outer peripheral surface of the hollow body 11 through the doctor gap 16. The toner toner is then conveyed on the same outer peripheral surface in a direction opposite to the rotational direction of the magnet roll 120 (in the direction of arrow C), passes through the lower surface of the toner guide 17, and reaches the lower end of the recording electrode pattern 20.

れる。The toner 14 that has reached the lower end of the recording electrode pattern 20 in this manner forms a toner chain 30 (toner particles connected in a chain along the lines of magnetic force emitted from the magnet roll 12) above the lower end. In a state where such a toner chain 3o is formed, the driver chip 21 selectively applies a voltage pulse between the recording electrode pattern 2o and the back electrode 28 based on the image signal etc. input from the external circuit 27. Then,
As in the case of the conventional device, the particles at the tip of the toner chain 30 on the selected recording electrode pattern 2o are moved to the recording medium 29 by Coulomb force against the magnetic force of the magnet roll 12, and as a result, , dots corresponding to the selected recording electrode pattern 20 are printed on the recording medium 29.
したがって、前記電圧パルスの印加と並行して、前記記
録媒体供給手段による記録媒体29の搬送が行われると
、前記画像信号に対応した画像が記録媒体29上に記録
されることになる。Therefore, when the recording medium 29 is conveyed by the recording medium supply means in parallel with the application of the voltage pulse, an image corresponding to the image signal is recorded on the recording medium 29.
他方、記録電極パターン20の下端部に達しだものの、

Toner particles that have not migrated to the recording medium 29 are removed by the recording head 18 from the hollow body 11 and the toner guide 1 as described above.
Since it is housed in the magnetic field of the magnet roller 12 together with the toner 7, it returns to the flopper 13 via the protective cover 22 of the recording head 18 and the upper surface of the toner guide 17. That is, in this apparatus, since the recording head 18 is housed within the magnetic field, the recording head 18 absorbs the toner 14.
transport is not obstructed.

ることができる。Now, in general, a rigid substrate has better mechanical strength than a flexible substrate, has less moisture absorption, and has good adhesion to a pattern, so it is easier to process a fine pattern. Therefore, if the recording electrode pattern 2o is formed on the rigid substrate 19 as in the present device, the density of the recording electrode pattern 20 will be higher than in the case of forming the recording electrode pattern on the flexible substrate as in the conventional device. can be significantly increased, and a density of 8 or more cells per pharynx can be easily obtained. Additionally, since the required number of recording electrode patterns 2o can be formed on one rigid substrate 19, there is no problem with the linearity of the arrangement of the electrode patterns 20 or the accuracy of the arrangement pitch. A high quality, highly reliable recording head can be obtained at low cost.

本)に比べ非常に少なく、その取りiいは容易であり、
かつトナー14の搬送の妨げとなることもない。In this device, since the driver chip 21 is mounted on the recording head 18, the device can be made smaller, and the wiring between the driver chip 21 and the recording electrode pattern 2o can be connected to the recording head 18. There is no need to route it outside. The recording head 18 receives image signals and the like through the external circuit 27 and the input line 26 as described above, but the number of input lines 26 can be several to several tens, and the recording electrode Number of patterns 2o (2048
There are very few compared to books), and it is easy to get them.
Moreover, the conveyance of the toner 14 is not obstructed.

For example, FIG. 4 shows a cross-sectional view of a recording head according to another embodiment of the present invention, and is an example using two substrates. That is, in this embodiment, a rigid substrate 19 made of ceramic on which the recording electrode turf 20 is formed and a rigid substrate 31 made of glass epoxy substrate on which the input side connection pattern 25 is formed are arranged adjacent to each other in a hollow space. The driver chip 21 is attached to the outer peripheral side of a body (not shown), and the driver chip 21 is attached to the two substrates 19 and 3.
It is installed according to 1.
