SU1207806A1 - Device for the typesetting of relief dot element image - Google Patents

Description

The invention relates to typhlotechics, namely, devices for the reproduction of relief-point texts.

. The purpose of the invention is to increase the convenience of operation and simplify the design.

FIG. 1 shows the device, general view, section; in fig. 2 is a view A of FIG. one.

The device for the set of the relief-spot image contains matrices 1 and 2 with coaxially arranged openings 3 and 4. One of the matrices, for example 1, is movable. The device also contains punches 5 with spherical heads 6 located in the matrix 1 for placing its ends 7 in the blind holes 4 of the matrix s 2, as well as the control element of the punches, including the magnetic element 8, which is fixed on the matrix 1 from the side heads of 6 punches a paramagnetic plate with holes 9 for placing the NIN heads 6 of punches 5 and a rod pusher 10 made of diamagnetic material for selectively contacting the heads of punches and placing a magnetic element in the holes 9. The holes 9 of the magnetic element are made coaxially with the holes 3 of the matrix 1. In this case, the matrices 1 and 2 are made of a diamagnetic material, and the holes of the matrix 1 are made through.

The device works as follows.

In the initial state, all the punches 5 are in the upper position and held in this position due to the residual magnetization of the plate of the magnetic element 8.

Blind, as in traditional writing, in a relief-dotted font, for example, in Braille, inserts the rod 11 of the pusher 10 into the hole 9 of the magnetic element corresponding to the image to be dialed. When this happens, the rod 11 presses on the corresponding punch 5, which opens from the paramagnetic plate, the attractive force between them decreases, and the punch 5 falls under the action of gravity into the corresponding blind hole 4 of the matrix 2,

When raising the matrix 1 and the paramagnetic plate in the blind holes 4 of the matrix 2, only those punches are left that correspond to the text written by the blind with the help of the pusher 10 (positive relief-point image). Other punches are magnetized to the magnetic element 8 due to the residual magnetization of the paramagnetic plate and are lifted up together with the plate and the matrix 1 (the guides along which the plate and the matrix 1 move vertically are not shown, or there may be, for example, appropriately curved ends of the matrix 2 ).

After the repetition of a typed relief-point image (for example, by overlaying a sheet, perforated paper on punches 5 located in the blind holes 4 of the matrix 2, and acting on it with a rubber roller) the plate of the magnetic element 8 and the matrix 1 are lowered down and either turned over the device of the matrix 2 is up, while the punches under the force of gravity fall down onto the paramagnetic plate, magnetize it and return it to its original position, or pass an impulse of electric current through the electromagnet winding 12 that bound by, the magnetic circuit with the magnetic element. The paramagnetic plate is magnetized and attracts punches 5 (matrices 1 and 2, made of a re-magnetic material, do not prevent their vertical movement), which after the end of the current pulse is held in the upper position due to the residual magnetization of the paramagnetic plate. The device is prepared for typing the following text (relief-point image).

Erasing typed information can be done line by line. To do this, a core 13 of an electromagnet in the form of a plate with the size of a line is superimposed or moved line by line on a paramagnetic plate and a current pulse is applied to the electromagnet winding. FIG. 2 with a double arrow showing the directions of movement of the core 13 of the electromagnet 12.

The application of the proposed device allows you to exclude the possibility
