DATA INPUT/OUTPUT APPARATUS.

摘要

A data input/output apparatus which has a controller (1), a tape punch (5), a tape reader (4) and a printer (6) and which can also be operated by commands from a host computer. The printer is provided with a data judging circuit for discriminating data which is not usually printed. When data, which is not usually printed, is detected by the data judging circuit, a signal for printing a character corresponding to the data is delivered to a printing part (6e) so that printing can be effected according to the number of digits set in a hit counter (6db) independently of the number of characters set according to data on the number of characters per line.
