    • PROBLEM TO BE SOLVED: To solve the problem that a conventional frequency abnormality detecting circuit, in which a monitoring clock uses a frequency higher than that of a clock to be monitored, is expensive, requires a countermeasure against noise, and is difficult to mount on a substrate, and also, a conventional frequency abnormality detecting circuit, in which the monitoring clock uses a frequency lower than that of a clock to be monitored, is not only unable to detect an abnormality depending on timing of clock fixing but requires a separate configuration that prevents a warning from being issued since all register outputs constituting a shift register become "0" during a reset.
      SOLUTION: An upper-limit abnormality of a clock frequency is detected by comparing the magnitude of a count value of the number of clocks to be monitored with that of an upper-limit value. A lower-limit abnormality is detected by an output of a logical AND of a positive pulse outputted at a rising edge of synchronized monitoring clocks, an initial edge hold circuit output that outputs "High" by the pulse output, and a comparator output that compares the magnitude of a lower-limit value and that of the count value of the number of clocks to be monitored.

    • PURPOSE:To simplify register business by setting a value, whose fraction is dropped or raised, at a claimed amount, and writing the dropped or raised fraction amount into a recording medium as the residual fraction amount of a next transaction. CONSTITUTION:Before the start of the commodity registration of a customer, by reading a magnetic card 30 possessed by the customer, a residual fraction amount 32 (X) recorded on the card 30 i set at a last residual fraction amount buffer 23. At the time of the completion of the commodity registration, the total amount (Y) of purchased commodities is set at a purchased total amount buffer 24. Here, the residual fraction amount X is subtracted from the purchased total amount Y, and its result (Z) is set at a temporary buffer 25. Next, according to the number of fraction digits set at a fraction digit number presetting area 26 beforehand, the value Z of the fraction amount is raised, its result is set at a claimed amount buffer 21 as a claimed amount (P), and a raised fraction amount (Q) is set at a present residual fraction amount buffer 22. Further, the fraction amount Q is written on the card 30.
