を有していた。There is a so-called dot impact type line printer KJIP, in which a plurality of printing hammers are placed adjacent to and across the printing paper, and printing is performed by swinging the printing hammers from side to side. As a method for absorbing vibration ta, a method is used in which a balancer having a mass corresponding to the mass of the printing hammer puncture is oscillated in a phase opposite to that of the printing hammer puncture. Conventionally, in this type of dot impact twin printer, there was no parallel printing process. The balancer and printing hammer puncture are placed in a space outside the horizontal swing range of the puncture, and at the same time, the balancer and printing hammer puncture are made to swing left and right on their own independent support guide members, resulting in a complex structure. A large amount of space is required inside the printer to accommodate the supporting and guiding member, which has the disadvantage of being a major obstacle in reducing the weight and size of the entire printer.

たドツトインパクト式ラインプリンタを提供できる。According to the present invention, the structure is simple and lightweight by guiding and supporting the balancer for absorbing the vibration of the printing hammer puncture on the same axis as the guide shaft for guiding and supporting the left and right swinging of the printing hammer puncture. Therefore, it is possible to provide a dot impact type line printer that can be miniaturized.

A printing hammer bank 1 includes a plurality of printing hammers 2 made of a ferromagnetic material in the shape of a leaf spring, a comb-shaped slot 4 fixed by sandwiching a permanent magnet 3, and a plurality of printing hammers 4 fitted in the teeth of each comb. It is mainly composed of 1.5 and 7.5 cm, and a light /SS mamank 7 and 6. The guide shafts 7 and 7' each have a straight cylindrical shape with both ends fixed to the seven frames 8. Hammer bank 7 frame 6 is on these two guide shafts 7) 7.7',

マ２による印字の際の衝撃力を受ける。Similarly to the balancer 9 and the frame 6, the balancer 9 is mounted on the two guide shafts 7) 7.7' so as to be movable left and right. A ninth motor 11 that swings the printing hammer puncture l left and right is fixed to the frame 8. An eccentric cam 13 is attached to the shaft 12 of the motor 11.
The ink ribbon 1'5 is fixed to the printing paper 16, and the eccentric cam 13 is fitted into the groove of the cam 7 and 4 forming a part of the hammer punch frame 6.
and the printing handle 12. The platen 17 is
7. It is mounted rotatably on frame 8. The platen 17 is rotationally driven by a known means (not shown), performs the function of feeding the printing paper 16, and at the same time receives impact force during printing by the printing hammer 2.
ここで第１図によって本実−の動作について説明する。Here, the operation of this device will be explained with reference to FIG.

Ru. At the same time as the hammer bank l swings left and right, the balancer 9 connected to the hammer puncture frame 6 by a leaf spring 10.10' swings left and right in the opposite phase to the printing hammer puncture 1, and the vibration of the hammer bank 1 is will be issued. The anti-phase synchronization with the printing hammer punch t9 of e and the printing hammer punch 1 is based on the deflection constant of the spring 10. This can be achieved by setting a value that is relevant to .
