Claims

[Scope of utility model registration request]

A movable member, a drive source that drives the movable member, a stopper that defines a moving end of the movable member, a stopper drive source that drives the stopper, a movable member position sensor that detects the absolute position of the movable member, and the stopper. It has a stopper position sensor that detects the drive amount of the drive source to detect the relative position of the stopper, and a movable limit setting switch that sets the position where the movable member reaches the moving end as the movable limit position of the movable member, Furthermore, a proximity state detection means detects the proximity or contact state between the movable member and the stopper, and an output signal value of the movable member position sensor when the movable limit position is set by the movable limit setting switch is used to detect the movement of the movable member. a movable limit setting means for setting a limit, and moving the stopper to a movable limit position set based on the set value of the movable limit position, the output signal of the moving member position sensor, and the output signal of the proximity state detection means. a stopper drive amount calculation means for calculating the stopper drive amount required for the movement; a storage means for storing the set value of the movable limit setting means; The position of the moving member at that time is obtained from the moving member position sensor, and the driving amount of the stopper drive source is calculated by the stopper driving amount calculating means by reading the movable limit set value from the storage means. calculate,
and stopper control means for operating the stopper drive source so that the stopper is moved to the movable limit position by the stopper drive source.
