〔発明の利用分野〕
本発明は印刷装置に係り、更に具体的にはインハクトカ
式の印刷装置、に関才るものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a printing device, and more specifically to an in-haul type printing device.

右の縁までの距離をａ。In the conventional printing apparatus, printing is performed by moving the gutter 2 at the center of the platen 1, as shown in FIG. Rlu
In the figure, the distance from the print head movement axis to the left and right edges of the platen is a.

するという問題があった。If b, then a = b. Although the platen 1 is made of a wear-resistant material such as ceramic, the impact of the print head can cause wear and tear on the platen 1.
When a dent occurs, according to the conventional configuration, there is a problem in that the platen 1 needs to be replaced with a new one, which requires expensive maintenance costs.

対向してその移動軸。In order to achieve the above objects, (1) the printing apparatus of the present invention positions the platen so that the axis of movement of the print head is offset from the center axis of the platen; A feature of the invention is that the same platen can be reused by changing the orientation of the platen even if the platen is worn or dented due to the impact of the print head. Embodiment FIG. 1 shows an embodiment of the present invention. In this embodiment, a flat platen 1 is removably attached to a bracket 6 with screws 4, and a print head 2 is connected to the platen 1Vc.
Opposing its axis of movement.

る。is located at a position offset from the central axis of the platen 1. That is, if the distances from the movement axis of the print head 2 to both the left and right ends of the platen 1 are a and b, the relationship is a+b. In addition, the platen 1 has two screw holes 4A,
4B are formed point-symmetrically, and each screw hole connects platen 1.
If the distances to both ends of 0 are c and d, then there is a relationship c=d.

Supplied o1. The print head 2 performs an impact operation while moving perpendicularly to the paper conveyance direction, and prints a uniform amount on 50 sides of the paper. One predetermined line can be printed by feeding the paper and tapering the above printing operation.

By rotating the axis 0 degrees or by installing it upside down, the unused surface of platen 1 can be placed at the impact position (
I can do that. Therefore, there is an advantage that the same grate can be used multiple times.

給できる点にある。Next, FIG. 6 shows another embodiment of the present invention.1-0 In the same figure, the same reference numerals indicate the same members as in the previous embodiment. The difference in construction from the previous embodiment is that the platen 1 is circular in shape, and a screw hole is provided in the center of the platen 1. A screw 4 is added to the C bracket 6. According to this embodiment, if the platen 1 becomes worn or dented, a new continuous surface can be provided by simply loosening the screw 4 and rotating the platen 1.
