A jig driving apparatus for moving a jig plate and workpiece mounted thereon relative to a jig body. The jig driving apparatus comprises a driven shaft rotatably mounted in the center of the jig body and underneath the jig plate and a converter for converting rotation of said driven shaft into motion of the jig plate relative to the jig body.

DETAILED DESCRIPTION In keeping with the principals of the present invention, the objects are accomplished with the unique combination of a jig body, a jig plate slideably mounted on said jig body for holding the work piece, a driven shaft rotatably mounted within said jig body and under the jig plate, and a means for converting rotation of the driven shaft into motion of the jig plate relative to the jig body.
Normally, the jig body is affixed in a single position in a machine or the like.
Accordingly, when the driven shaft is rotated, the rotation of the shaft is converted into motion of the jig plate and workpiece mounted thereon relative to the jig body.
Accordingly, it is a general object of the present invention to provide a means for moving or rotating the workpiece which is relatively small in size.
It is another general object of the present invention to provide a means for moving the workpiece about which is adaptable for use with an automatic machine.
