Title:
POSITION DETECTING SYSTEM
Document Type and Number:
Japanese Patent JP06262570
Kind Code:
A
Abstract:
PURPOSE: To always make an absolute position in multirotation detectable even if an inexpensive single rotation absolute position transducer is used.
CONSTITUTION: At the time of power making, marking information marked on each peripheral surface of toothed belts 2a, 2b, 2c is detected by three sensors 4a, 4b and 4c, thereby detecting each position of these toothed belts 2a, 2b and 2c. In addition, an output signal of a single rotation absolute position transducer installed in each of driving sources 1a, 1b, 1c and each position of these toothed belts 2a, 2b, 2c are connected together, through which a multirotation absolute position of the single rotation absolute position transducer is judged.
