Abstract:
1. A uniaxial drive unit comprising: a pulse drive motor having a fixed part and a moving part, which is driven by an applied pulse voltage; a fixed table; and a moving table which is supported so as to be slidable in the uniaxial direction with respect to said fixed table, wherein one of said fixed part and moving part is fixed to said fixed table, and the other of said fixed part and moving part is fixed to said moving table, a rotary pulse generating device having a knob, which is a device for generating an electric pulse for driving said pulse drive motor, is provided, said rotary pulse generating device generating a pulse of a frequency corresponding to the turning speed of said knob and generating pulses of the number corresponding to the turning angle of said knob, and fine feed is provided to said moving table by the pulse generated by said rotary pulse generating device.
