Claims

[Scope of utility model registration request]

From the light emitting unit, the first, second, and third photosensors, and the signals from the first, second, and third photosensors,
A position sensor having a decoder circuit that decodes into five types of signals, a movable table driven by a motor, etc.,
a light shielding plate that is attached to the moving base and blocks light from the three photosensors; the light shielding plate causes the first photosensor to receive light at the table origin position and the limit position; and the light shielding plate allows the first photosensor to receive light at the table origin position and the limit position. , causes the second photosensor to receive light, and causes the third photosensor to receive light when the movable base is in the forward direction position, and the output of the decoder circuit is such that due to the movement of the movable base, the light shielding plate is A position detector of a numerical control device configured to output five types of signals: table origin, table origin slow, + limit, - limit, and + position by moving between the position sensors.
