Abstract

PURPOSE: To enable the detection of rotary angle with good accuracy and a simple constitution, by producing the code signal through the coded rotary angle with the combination of electric conduction and non-conduction for the contact part between the rotary body and one or more rotated bodies.
CONSTITUTION: When the pointer 2 is between 0 and 1, the dispay unit 12 indicates 0. That is, only 0 signal is fed to the decoder since the large gear 1 is in contact with the non-conductive part of the first gear 4 to fourth gear 7. Next, the large gear is advanced by one tooth toward the arrow 13, then the fourth gear 7 only is changed to the conductive member gear 7a. Thus, the current from the power source feeds the signal 1 to the decoder 11 through the large gear 1, tooth 7a and shaft 7c and the display unit 12 indicates 1, and the display unit 12 indicates 1. Thus, as the revolution of the large gear 1, the indicated value is changed by the combination between the four pinions and teeth.
