前記表示素子を点灯制御するようにしたことを特
徴とする入力表示装置。 An input selection switch configured such that a first terminal and a common terminal are connected when not operated, and a second terminal and a common terminal are connected when operated, and a determination circuit connected to the first terminal of the input selection switch. and,
a signal input terminal connected to a second terminal of the input selection switch, a signal output terminal connected to a common terminal of the input selection switch, and a level variable means for varying the level of the determined signal to the determination circuit; and a display element controlled by the judgment output from the judgment circuit, and when the input selection switch is operated, the signal applied from the signal input terminal is sent to the signal output terminal via the input selection switch. At the same time, the determination output of the determination circuit is inverted by canceling the level control of the signal to be determined by the level varying means, and the lighting of the display element is controlled by this determination output. Input display device.
