发明名称 DISTRIBUTOR WITH A BUILT-IN CRANK ANGLE SENSOR
摘要 A distributor for an automotive engine with a built-in crank angle sensor includes a crank angle sensor unit 7A wherein the photodiode 12 opposing the light emitting diode 11 across the rotation disk 6 and the waveform shaper circuit for shaping the output of the photodiode 12 into a rectangular waveform are built into a single-chip photoreceptive integrated circuit 10. The photoreceptive integrated circuit 10A may include constant current source circuit consisting of a voltage divider 31a and 31b, a operational amplifier 32, a transistor 33, and current detector resistor 34, such that the current level through the light emitting diode 11 is kept constant.
