Abstract
A positioner includes: a base having a pair of support parts disposed with a prescribed gap therebetween in a direction of first axis; a shaft member disposed between the pair of support parts and is supported so as to be rotatable about the first axis relative to the base; and a disc-shaped rotary table supported to be rotatable about a second axis orthogonal to the first axis relative to the shaft member and having a mounting surface where a workpiece can be mounted, The rotary table has an outer diameter dimension that fits inward of both ends of the shaft member in the direction of the first axis, and in a movable range of the rotary table about the first axis.
Claims4
A positioner comprising:
- a base having a pair of support parts disposed with a prescribed gap therebetween in a direction of a first axis;
- a shaft member that is disposed between the pair of support parts and that is supported so as to be rotatable about the first axis relative to the base;
- and
- a disc-shaped rotary table that is supported so as to be rotatable about a second axis orthogonal to the first axis relative to the shaft member and that has a mounting surface on which a workpiece can be mounted,
- wherein the rotary table has an outer diameter dimension that fits inward of both ends of the shaft member in the direction of the first axis, and
- in a movable range of the rotary table about the first axis, a distance of the mounting surface from the first axis is set to be greater than a distance of an outermost edge about the first axis of at least one of the support parts from the first axis, and a distance of a rear surface of the mounting surface of the rotary table from the first axis is set to be less than the distance of the outermost edge from the first axis.
