り、従来から種々の方式の記録装置が作られてきた。Conventional configurations and their problems In recent years, with the spread of office automation, the demand for recording devices that convert electrical signals into visible images, so-called printers, has increased, and higher quality performance has been required. Various types of recording devices have been created.

要であり、記録装置の構造を複雑にしていた。As such, an electrode head that is capable of high-resolution recording has been proposed, in which the tip of the stacked body 3 in which electrically conductive layers 1 and electrically insulating layers 2 are alternately stacked is shaped into a V-shape. Since the tip of the character 7 is pressed against a recording medium such as discharge destruction recording paper, the contact surface of the electrode head with the recording medium is worn out due to discharge and friction, increasing the contact area and deteriorating print quality. In order to prevent deterioration of print quality due to this wear, a polishing device is required to keep the tip of the electrode head in a constant shape, which complicates the structure of the recording device.

FIG. 2a is a perspective view of an electrode head and a recording medium in one embodiment of the present invention. In FIG. 2a, 11 is discharge breakdown recording paper, a vapor-deposited aluminum layer 12, a black layer 13. It consists of a base paper layer 14, to which an electrode head 10 consisting of an electrically conductive layer 8 and an electrically insulating layer 9 is brought into contact for recording. The principle of recording has been explained in the conventional example, so it will be omitted for 5 pages. Further, FIG. 2 is a sectional view of the surface of the electrode head that comes into contact with the discharge breakdown recording paper, and in this embodiment, the pitch β of the lamination and the thickness t of the lamination are made to be the same size.

である。The feature of this embodiment is that the thickness t of the laminate is made equal to the pitch l of the laminate, and ■ Even if the tip of the electrode head is worn out due to discharge or friction during printing, the electrode head and discharge The contact area with the destructive recording paper does not widen and a constant contact area can be maintained at all times, eliminating the need for a polishing mechanism to keep the contact area constant. It has the feature that it is possible to make the resolution the same as the resolution in the stacking direction. This is a feature that cannot be obtained in the conventional example described above.

字品質が悪くなる。In this example, the thickness of the laminate was made the same as the pitch of the laminate, but even if the thickness of the laminate was increased to twice the pitch of the laminate, the image quality would depend on the thickness of the laminate. Although the print quality deteriorates accordingly, the print quality remains good.If the thickness of the laminate exceeds twice the pitch of the laminate, the shape of the printed dots becomes unstable and the print quality deteriorates.

FIG. 3 is a perspective view of an electrode head according to another embodiment of the present invention. In FIG. 3, 8 is an electrically conductive layer, 9 is an electrically insulating layer, and 10 is an electrode head consisting of the electrically conductive layer 8 and the electrically insulating layer 9. Detailed explanation will be omitted. An electrically insulating support 16 is provided on the rear side with respect to the direction of movement of the electrode head.

る。熱伝導の良いアルミナ基板等を用いると良い。For example, the thickness of the laminate is 100 μm if the printing resolution is 10 dots per 1 rrrIn;
If there are 20 dots per layer, the thickness is 60 μm, and the higher the resolution, the thinner the layer becomes, making the laminate more likely to break. To solve this problem, it is possible to prevent the laminate from folding by providing a support behind the electrode head. However, when a resin is used for the support, the support may be deformed by the heat generated by discharge during printing, making it difficult to obtain stable printing. It is recommended to use an alumina substrate or the like that has good thermal conductivity.

To prevent dust and debris from adhering to areas other than the contact surface with the recording medium during recording. In addition, it is also possible to send out the laminate when the contact between the laminate and the recording medium deteriorates due to wear. In the non-example, supports 1 and 1B were made of the same material, but they were made of different materials.

録体に傷がつくのを防ぐことが可能でおる。In FIG. 6, the one-electrode head 10, the electrically conductive layer 8, and the electrically insulating layer 9 are the same as those in FIGS. 2, 3, and 4, and therefore their description will be omitted. If the end surface of the support is in the same plane as the contact surface of the electrode with the recording medium as shown in Figures 3 and 4, the contact between the support and the recording medium will cause scratches on the surface of the recording medium. GO-72733 (3) may be passed. In order to solve this problem, the support 19
By shortening the length of the support as shown in the figure, it is possible to prevent the support from coming into contact with the recording medium even when the electrode body is in contact with the recording medium, thereby preventing the recording medium from being scratched.

き、安定した品質の印字が得られる。Effects of the Invention As is clear from the above explanation, the present invention forms a laminate by alternately laminating electrical conductor layers and electrical insulating layers at a constant pitch, and the thickness in the direction perpendicular to the lamination direction is The laminate is formed so that the pitch is constant in the vicinity of the contact portion with the recording medium and is twice or less than the pitch, and one end of the portion of the laminate that is twice or less is pressed against the recording medium to form an electrical conductor. Recording is performed by energizing the connection between the layer and the recording medium, so the resolution of the print can be easily changed by simply changing the pitch of the lamination, and the 9/9 of the laminated body due to friction during printing can be easily changed. - Even when the laminate is worn out, the thickness of the laminate is constant, so the contact area with the recording medium remains unchanged, and the printing resolution can be kept constant, resulting in stable quality printing.
