Abstract

PURPOSE: To ensure the secure actuation of a stopper by detecting the displacement of a movable shaft by means of a differential transformer to turn on the switch circuit without exact setting of opposed distance between movable shaft rear end and contact-maker.
CONSTITUTION: A stopper member 4 is screwed to the bracket 6 on the table 1. A smaller-diameter portion 8a of the movable shaft 8 slides freely into the pipe 7 screwed to the female screw of the stopper member 4. The end 8c of the movable shaft 8 protrudes outside the stopper surface 4a by a given length. The holder 11 installed on the pipe 7 is provided with a coil 15 of the differential transfomer 14, while the iron core 16 of the differential transformer 14 is fitted to the rear end of the movable shaft 8. Under the above-mentioned constitution, the position of the iron core 16 when the movable shaft 8 abuts on to the wall surface 9 of the stopper member 4 is electrically set at zero. When a carriage 2 pushes the end portion 8c, displacement in the left direction of the iron core 16 is detected electrically and the switch circuit of the carriage 2 is turned on to stop the operation of the carriage.
