Abstract
1316787 Reciprocating generators CANON K K 12 June 1970 [13 June 1969] 28631/70 Heading H2A A signal generator, particularly for producing input signals to a computor comprises a key 61 movable against a resilient bias 13 so as to cause a permanent magnet 63, carried by the key, to produce a reversal of polarity in a member 70 of semi-hard magnetic material and thereby induce an output signal in a coil 71. As shown U-shaped members 62, 66 of soft magnetic material are supported by the key 61 on opposite sides of a fixed soft magnetic material member 69 which embraces the coil 71 and member 70. In the inoperative position of the key a magnet 67 carried by the member 66 engages and polarizes member 70 as shown. Pressure on the key disengages magnet 67, and magnet 63 then engages and reverses the polarization of member 70.
