Description

In the well-known braille type letters, using a blind with a notch at the bottom, the inventor proposes devices in two versions: in the first embodiment, a multi-faceted drum equipped with planks with convex dots for crimping is used, according to the second variant, one fixedly reinforced plank with convex points and two rollers for pulling the paper at line spacing.

In FIG. 1 shows a vertical section of the device according to the first embodiment; FIG. 2 shows the device according to the first embodiment from above; FIG. 3 is a vertical section of the device according to the second embodiment; FIG. 4 - types of individual parts of the device in the section and above; FIG. 5 - vertical-ny section of the swage with a ball notch at the bottom and strips with a convex point.

A hexagonal reel 3 (Fig. 1) with strips 4, each of which represents a row of protuberances corresponding in size and location to normal Braille, is placed in the notch of the bar b and rotated using the flywheel 8 mounted on the axis 7 of the reel 3. From above, A bar 10 with guide windows 11 is attached to the bar b under the drum strip 4 to guide the crimping tool 1 to the corresponding point of the letter. For the passage of paper when printing between the guide bar 10 and the bar 4 are slotted notches 9 in the bar 6.

Printing is performed as follows. The paper is loaded through the notches 9 of the beam b between the strips 4 and 10 and pressing the pressing 1, after that the handwheel 8 turns the drum 3 by one sixth of a full turn, and since the paper is pressed by the strips 10 and 4, it turns on width between lines. By the next pressing of the crimp 1, the next line is printed, etc.

In the second embodiment, the strips 4 (Figs. 2, 3, 4) with point protuberances 5 are attached to the beam b, to which the strips 10 are attached with guide windows 11 to the bar 10. The rollers 13 and 14, pressed against each other, serve moving the paper after printing one line.

Printing on the device of this device is as follows. The paper is pulled into the gap between the slats 4 and 10, and the edge between the rollers 13 and 14. Pressing the pressing 1 produces bulges on the paper corresponding to the bulges of the plate 4, after which the paper moves the width between the lines by rotating the rollers 13 and 14.

The subject matter of the invention.

1. A writing device with a Brai Ethe font blind, with the use of a crimp, equipped with a recess at the end, characterized by the use of a multifaceted drum 3 equipped with slats 4 with convex dotted signs, the number of which corresponds to the number of letters in a line, and a slider 10 with directions The pressing windows 11 for pressing 1, for turning which drum when moving to a new line, is the handwheel 8 (Fig. 1, and 4).

2. The form of the implementation of the fixture referred to in claim 1, characterized by the use of only one plank 4 fixedly fastened in bar b, and two rollers 13 and 14 for pulling the paper at inter-spacing (Fig. 2, and 3).
