Abstract

PURPOSE:To obtain a stable operation capable of constantly maintaining the display position of a display screen at all times by comparing the display position instructing digital signal of the display screen with a digital signal representing the display position of the display screen, thereby controlling the stoppage of the display screen. CONSTITUTION:A voltage is generated at a tap transformer 102 in the step of designating the rotary switch 103 of an instructing unit 100. This voltage is rectified through a connecting wire 202 by a rectifying circuit 301 of an indicator 300, is converted by an A/D converter 302 to the display position instructing digital signal of a display screen, and is compared with the display position signal of the display screen from a switch 305-1 having switches S1-S6. A positively inverting amplifier 307 and a relay 308 are operated by the compared result, a normally open contact 309 is closed to positively invert a motor 313 or a reversely inverting amplifier 310 and a relay 311 are operated, and a normally open contact 312 is closed to invert the motor 313. When both signals become coincident with each other, the relay 308 or 311 is restored, and the motor 313 is stopped.
