Abstract

PURPOSE:To make easy the setting of secret rule and to omit the confidential part in the secret unit main body, by storing the content of rule in advance to the memory means prepared separately and setting the rule of the code converter used for secret communication system through the conversion of non-contact delivery means. CONSTITUTION:The rule set unit 9 consists of the keybaord 10, RAM 11 possible for readout and write-in storing the rule set with the keybaord 10, and electric photo conversion section 12 performing electric photo conversion for the output of RAM 11. With this cnstitution, the keyboard 10 is provided with the rule set key 14, clear key 15, memory signal key 16, start key 17, address display light emitting element 18, rule display light emiting element 19, and light emitting probe 20. This probe 20 is in contact with the photo detection section 21 placed in the code conversion circuit 13. After that, in case of code conversion, the operation of code conversion is made for the circuit 13 by depressing the start key 17. Thus, since no secret is present in the circuit 13, the confidentiality can be perfect.
