Abstract

PURPOSE:To avoid the malfunction of the control device with the photoswitch provided at the optical fiber cable transmission line, by increasing the light volume at the projection part when the photoswitch is turned on with the light entering the light reception part. CONSTITUTION:The light sent from LED16 enters phototransistor 19 at the light reception part via optical fiber cable 17 and photoswitch 18. The output of amplifier 20 is turned into the signal of a fixed level according to the intersity of the light. This signal increases the luminance of LED16 via comparator 21 and signal processing circuit 12. In this case, even through the optical axis may shift due to the vibration and other factors to vary the light intensity, no malfunction is caused since the output level of LED16 increases.
