PURPOSE:To extend the conventionality of a check function, by making the data check with a plurality of referencing data and performing logical operation as the result. CONSTITUTION:This figure is a block diagram of a field data check section in a system, and the section has a function to check the proficiency of recognized characters. Character data RD from the system recognizing section are stored in a data register 21. The data RD is compared and operated at an operating device with a plurality of reference data R1 and R2 stored in a reference register 22. The result of operation is stored in a resulting register 24. To contents R3 and R4, the logical operation by an OR circuit 25-1 and an AND circuit 25-2 is executed. From the result of logical operation, a control circuit 26 discriminates the proficiency of the data RD and transmits the result to an alarm control section of the system. |
