。[Claims for Utility Model Registration] In an origin finding device for a drive device that detects the relative position of a drive body that is linearly or rotationally displaced with respect to the drive means, (a) either one side of the drive means or the drive body; (b) first and second switch members fixed to the other side of the drive means and the drive body; (c) information from the first and second switch members; control means for determining the relative position of the driving body based on the position of the driving body, the fixing member having first and second regions, and the first region discriminating the relative position of the driving body from the first switch member to the driving body. is in a first state when the driving body is within a predetermined operating range, and is in a second state when the driving body is outside the predetermined operating range, and the second region is in a state in which the second switch member is in the predetermined operating range. When the driving body is at one end of the predetermined motion range with respect to the origin, the third state is set, and when the drive body is at the other end of the predetermined motion range with respect to the origin, the fourth state is set. The control means determines the direction required to move the driving body toward the origin by identifying the state of the second switch member, and the control means determines the direction necessary to move the drive body toward the origin, and the control means determines the direction necessary to move the driving body toward the origin, and the control means By identifying when the state changes from one of the first and second states to the other state, it is determined that the driving body is located at the origin, and the origin search is performed, and the state of the first switch member is changed to the third state.
and a fourth state, and determines a drive limit of the drive body by identifying a change from one of the states to the other state.
