Positioning system has personal computer that controls drive mechanism of controlled object based on output of absolute sensor that detects absolute position of controlled object

摘要

A driving circuit (64) in a PC card (6) that is mounted in a personal computer (7), drives an absolute sensor (3) that detects absolute position of a controlled object (2). A converter (62) converts the output of the sensor into a digital signal based on which the computer controls a drive mechanism of the controlled object.
