Abstract

PURPOSE: To enable Braille points to be read at a fixed position without requiring the reader to move its fingers, by changing situation of projection of points producing devices, which are arranged around a cylindrical rotor, in turn by means of a Braille points producing mechanism operating synchronously with rotating speed of the cylindrical rotor.
CONSTITUTION: A cylindrical rotor 11's rotating axle 11A is supported in a frre-to- turn position by bearing plates 14A and 14B, and its rotation is driven by a pulse motor 15. A round column-like pin 17 which is a dot member is provided with V- shape grooves 18A and 18B, and steel balls 20 which are moved by a spring 19 are fit into the groove at 2 positions. The cylindrical rotor 11 is provided with 6 units of Braille points producing devices 22AW22F with 6 column-like pins 17aW17f as one unit, 6 plungers 24AW24F which make all the column-like pins 17aW17f pro ject and a resetting cam plate 23. In this mechanism, a reader is able to read a series of letters simply by placing a hand (fingers) on fixed read-out opening 12A without being required to trace by moving its fingers.
