The invention relates to printing devices and can be used in symbol-synthesizing and direct-printing devices, in particular, in input-output devices in a computer.

The purpose of the invention is to improve the printing quality of information and expand the field of application by using a mosaic printing device for character printing.

Fig, 1 shows the proposed printing device, a general view; figure 2 - section aa on fig.k

The printing device contains an actuator for dot printing information, made in the form of a modular design. The module (Fig. 1) has a housing 1 in which elements of the magnetic system 2 (permanent magnets) and printing elements 3 "are installed.

The printing elements 3 are made in the form of plates of foiled dielectric. On two sides of each plate there is an electrical conductor, covered with a dielectric film. The impact ends of the printing elements 3 are arranged in one line in the form of a continuous row. In front of the working surface of the printing elements 3, shock tips 4, made in the form of plastic-pressed leaf springs 5, are placed. The springs 5 are attached to the body 1, have oblique projections 6 and are held by the elastic properties of the material. The reverse (not working) side of the impact tip 4 is located in front of the working surface of several printing elements 3 at the same time. On the supporting drum 7 there are placed letters 8.

The printing device operates as follows.

When an electric pulse is applied to the flat coil of the printing element 3, the latter is pushed out of the magnetic field created by a) a) 1 magnets 2. In this case

.-

The impact tip 4 moves in the direction of the drum to the letter carrier and impresses the character on the paper. Depending on the surface area of the symbol, one impact tip 4 may be actuated by one or several printing elements 3 simultaneously. To print characters with a small surface area, for example:.;,;; :;; etc., a small number of printing elements are sufficient. 3. To print characters that have a large surface area, for example: F, S, S, S, etc. So, it is necessary to simultaneously include a large number of printing elements 3, Continuous mode one or another number of printing elements, depending on the surface of the symbol, is specified by an electronic control unit (not shown)

Claims (1)
