Abstract
PURPOSE: To form a rotating angle detector of simple construction and thin type by consturcting the device so as to respectively separatedly drawing out index signals and pitch signals from one angle identifying rotor.
CONSTITUTION: The outputs (a) and (b) of angle detectors 2 and 3 are subtracted by a subtraction circuit 4 to become the waveform (c). A waveform shaping circuit 5 draws out the portions of the positive polarity of the waveform (c) after pulsing the same to the waveform (d) and one index signal per revolution of an angle identifying rotor 1 is obtained from output terminal 9. On the other hand, the signals (e) and (f) which comprise pulse shaping the outputs of the angle detectors 2 and 3 in waveform shaping circuits 6 and 7 respectively are integrated by a logic integrating circuit 8 to the waveform (g) which is then outputted as the pitch signal produced per rotating angle θ from output terminal 10. In this way, the index signals and pitch signals may be drawn out respectively separatedly from one angle identifying rotor.
