摘要: 945,033. Teaching the blind. ORYX TRADING A. S. March 18,1960, No. 9797/60. Heading G5G. Reading apparatus for blind conforming to braille system comprises a casing 10, reading platform 16 through which one or more rows of pins arranged according position Braille code may be projected data recorded as conductive ink areas on sheet 15 placed flat platten 13 movable stepwise in line spacing direction under contact carrier 98. A motor 64 drives shaft 66 engaged by 98 traverse it so that contactor 106 scan contacts 114,116 rail 112 is held with row 15. Signals from are passed an amplifier 120 pin 121 runs over 124 synchronism contacter traversing 112. Segments connected solenoids 125 actuate 18, sensed, then elevated. Thus sensed set up 18 projection can adjusted raising lowering cams 78 operated knob 20. Depression 21 rod 40 closes 60 start 64, operates arm 44 effect escapement pawl and rack 48, 50 space platen 13, 133, moves 130 cause fingers 129 restore previously scanned line. The alternatively right left threads reaches end thereof backwards forwards at left-hand finger 104 opens 105 stop motor. If desired two sets alternately provided case stopping means each depression effected alternately. Correct positioning 140. When correct position, 136 operate buzzer 138 while 92 indicates being sensed.
