電力化が重要となる。FIG. 1 shows a conventional example. In the data input unit 10, the input operation unit 1 is usually constituted by a switch on a keyboard, etc., and is connected to an optical signal generation circuit 2. The optical signal generating circuit 2 checks the contact state of the key switch. When a key press is detected, the optical signal generating circuit 2 generates an optical signal modulated with a code corresponding to the key, and drives the light emitting element 3. On the other hand, in the main device 20 , when the light receiving element 4 receives the optical signal, it converts it into an electrical signal and inputs it to the signal detection circuit 5 . Signal detection circuit 5
adjusts the input signal ta, generates a key manual signal, and transmits it to the control section 6. In general, the input section 1o is battery-powered in order to be portable, and low power consumption is important in the circuit configuration.

データ転送の信頼度確保が困難でめった。In order to reduce power consumption, this data input section 10 adopts a method of generating an optical signal only when a data input operation such as a key press occurs. Therefore, the main body Miii20
Even if there is a situation where the optical propagation path cannot be secured and the data input function cannot be guaranteed due to the positional relationship between the input unit 10 and the input unit 10 (presence or absence of obstacles, etc.), the situation cannot be confirmed in advance.
Ensuring reliability of data transfer was difficult and rare.
