装置。 In a keyboard input device that remotely controls a keyboard side and a host side using infrared rays, the keyboard side is provided with a flip-flop circuit, a delay circuit, a buzzer circuit, a code transmitter, and a confirmation signal receiver, and the host side is provided with a key code. A receiving section and a confirmation signal transmitting section are provided, and when a key is detected from the keyboard, the code transmitting section transmits a key code, and the flip-flop circuit is set, and the key code receiving section on the host side sends a predetermined key code. If a confirmation signal is received, the transmitting section on the host side transmits a confirmation signal to the receiving section on the keyboard side, and when the receiving section receives this signal, it resets the flip-flop circuit, and if it is not received, the flip-flop circuit resets. A keyboard input device characterized in that the buzzer of the buzzer circuit is held in a set state and a buzzer of the buzzer circuit sounds through the delay circuit.
