DETECTOR WITH SETTING FUNCTION

摘要

PURPOSE:To rapidly and accurately perform the calibrating work of a set value by rotating and abutting an extruding part formed on the outer circumferential part of a shaft rotation regulating plate upon a stopper to regulate the rotational angle range of a rotary shaft of a setter body. CONSTITUTION:When a dial knob 116 is rotated, a projecting part 7c of the shaft rotation regulating plate 7 on a lower superposed position and a projecting part 7c of the plate 7 on an upper superposed position are abutted on the side end face of a stopper chip 110e of a blacket 110 on a prescribed rotational angle position in the clockwise and counterclockwise directions of said rotation. The upper limit value and lower limit value of the rotational angle range of the rotary shaft 115a are regulated by said abutting. Since the shaft rotation regulating plate 7 provided with the projecting part 7c is fitted to a dial collar part 116b of the dial know 116 and the rotational angle position of the dial knob 116 on the regulating plate 7 is continuously adjusted through its long holes 7b1, 7b2, the rotational angle regulating range of the rotary shaft 115a in the clockwise and counterclockwise directions can be continuously changed.
