ことを特徴とする位置決め装置。A screw shaft attached to the frame so that both ends can rotate,
a mounting table on which the object to be processed is placed, which moves in the axial direction without rotation due to the rotation of the screw shaft, which has a built-in screw nut screwed onto the screw shaft; a pulse motor with an output shaft connected to rotate the screw shaft;
A pulse generator that generates a voltage pulse to rotate the pulse motor, and outputs an axial starting point signal to the pulse generator when the stand is located at the first end of the screw shaft of the mount. A screw shaft start point signal generator outputs a rotation direction start point signal every time the pulse motor rotates once in synchronization with one predetermined voltage pulse among the plurality of voltage pulses that rotate the pulse motor once. a motor rotation signal generator, which corresponds to the number of voltage pulses supplied from the pulse generator to the pulse motor, counting the time when the axial direction start point signal and the rotation direction start point signal match as a counting start point; a storage device that stores the actual measured movement amount of the table, and a desired movement amount of the table is input, and the pulse generator generates the pulse from the pulse generator corresponding to the desired movement amount from the stored contents of the storage device. Find the required number of voltage pulses to be supplied to the motor,
When the number of voltage pulses supplied from the pulse generator to the pulse motor reaches the required number of voltage pulses, the operation of the pulse generator is stopped and the table is controlled to move by the desired amount of movement. A positioning device characterized by comprising a control device.
