Abstract

PURPOSE:To remove a connection terminal, a connector, and a transmission cable and to improve operativity by utilizing the light emitting element and photodetecting element of a bar code reader and transmitting data forth and back between a data input terminal equipment and a data processor on optical communication basis. CONSTITUTION:The bar code reader 15 is connected to a data reading I/O port 37 and a data transmitting I/O port 38 through a selecting circuit 40. When a bar code is read, a selecting I/O port 39 outputs L and the data reading I/O port 37 outputs H, so that a light emitting diode 15a turns on at any time. Light reflected by the object bar code is detected by a photodetecting transistor 15b and sent to the data reading I/O port 37. The bar code reader 15 is plugged in the light input/output port 25 of the data processor during transmission and H is outputted from the selecting I/O port 39, thereby connecting the data transmitting I/O port 38 to the data processor.
