ABSTRACT:
A first signal generating apparatus generates unit angular signals at predetermined angular intervals, in relation to the revolution of a first rotary shaft. The first signal generating apparatus generates a first reference signal which has a different timing than that of the unit angular signals. A second rotary shaft completes one revolution while the first rotary shaft completes two revolutions. A second signal generating apparatus generates a second reference signal with every revolution of the second rotary shaft. A counting apparatus counts the unit angular signals and stores the counted value, and initializes the counted value every time the first reference signal is generated. An angular detecting apparatus determines whether or not the second reference signal is generated by the second signal generating apparatus. Based on the result of this inquiry, the angular detecting apparatus measures the rotational or angular displacement of the first rotary shaft.
