を検出することを特徴とする機械原点検出装置。 A target object feeding device for moving a target object onto a shaft having a feed screw of a predetermined pitch, a speed command means for rotating a motor directly connected to the shaft, a limit switch with which the target object comes into contact and sets a machine origin; In the mechanical origin detection device, the machine origin detection device includes an encoder that emits a marker signal that changes to a high level once per revolution of the motor, and an origin detection means that detects the origin, wherein the encoder emits an A-phase pulse and an A-phase pulse in addition to the marker signal. A waveform shaping circuit and a signal switching circuit are provided to emit B-phase pulses and to shape the A-phase pulses and B-phase pulses into forward/reverse rotation signals, and the marker signal is set to the A machine origin detection device characterized in that the origin is detected by switching based on a forward/reverse rotation signal.
