CONSTITUTION:When a tape transfer means 14 of a tape device 2 is working, the contents is displayed 20 for a counter 22a that countw the output pulses of a Hall device 8a. The contents are displayed 20 for a counter 22b that counts the output pulses of a Hall device 8b when a tape transfer means 16 is active. Then the contents of the couhters 22a and 22b are alternately displayed 20 in case the means 14 and 16 are active at one time. In this case, the contents of the counters 22a and 22b are displayed in different patterns for discrimination. |
