ABSTRACT:
An encoder includes comparators CP4and CP5which are provided in such a manner as to correspond to phase A and B respectively and detect a state where the output voltages deviate from their normal ranges. Transistors TR4and TR5which operate according to the outputs of the respective corresponding comparators are connected through resistors R8and R18,respectively, to an output line of phase Z. When each output line connecting to a phase-A output terminal QA or a phase-B output terminal QB is short-circuited to ground, or a signal line41A or42B connecting the output terminal with a electronic control unit40is broken, the transistor TR4or TR5is turned on and the output of phase Z falls below its normal range, thereby a malfunction is detected. Even if one of the transistors of phase A and phase B breaks down, a malfunction in the other phase is transmitted to phase.
