<p>A data input/ouput device comprises a controller (1), a tape punch (5), a tape reader (4), and a printer (6) and can be operated by commands from a host computer. A data discriminator identifying line feed code data is provided in the tape punch (5), the discriminator transmits line feed code data and return code data to the punching unit when it detects line feed code data, so that a line feed code and a return code are punched in sequence. A data discriminator identifying continuous code data consisting of a line feed code and a return code is provided in the tape punch, it transmits only the line feed code data to the punching unit when it detects the continuous code data, so that the line feed code is punched. </p> |
