In the proposed device, for the purpose of writing on both sides of the sheet, a plate with two rows of protuberances and tailings and a guide plate with holes are used.

In the schematic drawing of FIG. 1 shows the device in vertical section; FIG. 2, 2, 3, 3, 4, 4i, 5, fitting parts from above and in section; FIG. 6 shows a second variant of the guide plate from above and in section.

A blind writing device in Braille braille consists of plate 1 with two rows of bulges and voigutities arranged in a checkerboard pattern and guide plate 2

with holes 3, 4, also arranged in a checkerboard pattern. Printing is carried out on both sides of the sheet, usually using a tattoo for working with indented rows, and crimping for convex. In addition, the guide plate 5 is moved along the rollers 6, provided with notches 8 for the snap spring 9 to be mounted against the corresponding word (Fig. 5, 5) ..

Rollers 12 and 13, pressed against each other, serve to move the paper after printing a single line. In the second variant, the plastic guide consists of an upper plate 10 with a normal slot, to which a second plate 11 is attached, which is provided with six holes with a diameter corresponding to the thickness of the imprint or swage (Fig. 6, 6).

Thus, fumbing with a headdress or a snap of a point remains normal, but the direction is more accurate.

The blind one does not need to remember on which letter of the given line he stopped,
