復帰機構。[Claims for Utility Model Registration] A moving shaft having a moving part and a moving support part is provided with an origin detection limit switch and an origin detection dog to which the origin detection limit switch is inserted, and when the moving part moves in the direction of returning to the origin, the origin detection limit switch is activated. In an NC machine tool that detects the home position when the home position detection dog is turned on, a return start point detection limit switch and a return start point detection dog that closes the return start point detection limit switch are used so that the closing operation is performed at the same time as the home detection limit switch is turned on. is provided on the moving axis, and furthermore, when the return start point detection limit switch is turned on, the moving part is moved a predetermined amount in the opposite direction to the home return direction, and after the return start point detection limit switch is released, the moving part is moved. An automatic origin return mechanism for an NC machine tool, characterized by having a control section that moves the moving part in the origin return direction and moves the moving part directly in the origin return direction when a return start point detection limit switch is released.
