り光信号を受信しポータブル端末１に送る。FIG. 2 is a detailed diagram of the barcode input mechanism 2 inserted into the transfer adapter 3. The barcode input mechanism 2 is composed of a light emitting element 6 and a light receiving element 7. In the case of barcode reading, the light receiving rate of the light receiving element 7 differs depending on the reflectance of the barcode, so that the light emitted from the light emitting element 6 is barcoded. It is possible to read. In the case of transmission from the portable terminal 1, the light-emitting haiku of the light-emitting element 6 is received by the light-receiving element 9 on the transfer adapter side, converted into an electrical signal, and then transmitted to the host computer 5 through the cable connection connector 10. Conversely, when transmitting data from the host computer 5 to the portable terminal 1, the data is transferred to the transfer adapter 3 through the cable connector 10 and converted into an optical signal by the light emitting element 8. On the portable terminal 1 side, the terminal side light receiving element 7 receives the optical signal and sends it to the portable terminal 1.
