Abstract

1,268,854. Braille typewriters. ISRAEL PRIME MINISTER'S OFFICE. 14 Aug., 1969 [20 Aug., 1968], No. 40649/69. Heading B6F. Apparatus to enable a standard typewriter to additionally record in Braille comprises a plurality of character-key switches, one for each key, a Braille recording device 22, and an electrical switching network 18 connected between the recording-pin actuator solenoids of the recording device 22 and the character-key switches. The switching network 18 includes a diode matrix (19, Fig. 2) having an input line for each character-key switch and an output line for each recording-pin actuator. AND-gates connected to the ease-shift key switch and the switches of double-element keys (Fig. 3) have their outputs connected to the switching network. Pulse generators are connected to the record sheet advancing means 26 in the Braille recorder 22, and apply pulses to advance the record sheet following each depression of a character key, including the space-bar key. The switches may be incorporated in the typewriter keyboard or in a special stand 10 upon which the typewriter stands, so that the key levers co-operate with the switches.
