Claims

[Claims for Utility Model Registration] 1. A two-system input switching circuit that is provided with a plurality of input terminals and selects and switches one of them, and a transmission system switching circuit that displays the selected two input functions. In the display device, a setting means for prioritizing a main system input switching circuit;
a display means for displaying this main system priority mode;
The present invention further comprises a switching means for selecting one signal from a plurality of input signals of each of the systems, and a display means for displaying the input functions of the selected input signals of the two systems on a set of indicators. Characteristic transmission system switching display device. 2. In addition to the three modes of turning on, blinking, and extinguishing the display lamp of the input display, a flashing means is provided to change the blinking interval of the display lamp, thereby realizing many modes beyond the three modes, and making it possible to use many transmission systems. 2. The transmission system switching display device according to claim 1, which is capable of switching. 3. The transmission system switching display device according to claim 1, comprising switching means for controlling the input switching circuit and the output switching circuit to switch the input/output circuit of the transmission system, and display means for displaying the input/output function resulting from this switching.
