Abstract

See full text

Tables having nuts are easily assembled and/or replaced on a lead screw from an open side thereof. The lead screw has a large screw near a motor and a small screw remote from the motor. A right-handed screw mating with one of the nuts and a left-handed screw mating with the other of the nuts lie adjacent to each other in the lengthwise direction. A stepped portion of flange coming into an inner ring of a bearing is placed on an end shaft in adjacency to the large screw. The pair of the tables after energization of the motor is controlled to come to a preselected phase in which the tables get closer or nearer each other or come to another preselected phase in which the tables go away from each other.
