Abstract

PURPOSE:To realize an improper-operator check system which provides high- secrecy operation only by an operation key without using a magnetic card, etc. CONSTITUTION:Operator 7 inserts operation key 8 into terminal input part 10 for mnemonic-number input operation 9. Input mnemonic-number data 15 of data 11 to unit 2 is sent from mnemonic-number input circuit 3 to comparator circuit 6. Data 12 from operation key 8, on the other hand, is converted into key-number data 13 by operation-key number detection circuit 4 before being sent to memory- unit control circuit 5. On the basis of data 13, circuit 5 retrieves on memory unit 1 to read registered mnemonic-number data 14 corresponding to data 13 and the read out data is compared with 15, thereby generating coincidence signal 16 or dissidence signal 17. In this way, the operation key can be operated without using a magnetic card, etc., to improve secrecy and also to prevent an accident due to the losing of the card.
