Abstract
PURPOSE:To non-polarize a remote control cable with a very simple and small-sized constitution by providing, at an operating part side, the control means of a current varying means and a displaying means and, at a device main body side, a detecting means to detect the operation condition of a voltage variable means and a switching means. CONSTITUTION:At an operating part 21 side, a current varying means R to change a current to flow between the two lines of a cable 12 corresponding to the operation of a switching means S and a control means 14 to control the action of a displaying means L based on a voltage change between the two lines of the cable are provided. On the other hand, at the titled device side, a voltage varying means Tr to change a voltage between the two lines of the cable 12 and a detecting means 27 to detect the operation condition of the switching means S based on the change of the current to flow between the two lines of the cable are provided. When the switching means at the operating part side is operated, the current varying means changes the current to flow between the two lines of the cable, and the detecting means at the device main body side detects the operation condition of the switching means. On the other hand, when the voltage varying means at the device main body side changes the voltage between the two lines of the cable, the control means at the operating part side controls the action of the displaying means. Thus, cable can be non- polarized by the simple and small-sized constitution.
