Abstract

PURPOSE:To enable to retrieve the stored information as it is, by monitoring a keyboard having a character key with a key input circuit and making retrieval of data memory with the retrieval program of a program memory. CONSTITUTION:The keyboard 1 having the character key has the alphabet of A- Z, clear key and conversion key, and the key input is always monitored with the key scanning signal from the input circuit 2. When the specified character key is depressed on the keyboard 1, the input key is judged at the circuit 2, the character code is written in the register RG51, the control circuit 3 is driven, the retrieval program is read out from the program memory 4, and executed. The content of the address of data memory 6 designated at the address RG61 is read out at RG52 and it is compared with the content of RG51 at the subtractor 53, and when in agreement, the retrieval is finished, and the next character is retrieved. If the contents of RGs 51, 52 are in disagreement, RG61 is renewed with the adder 62, and retrieval is advanced until being in agreement to enable the retrieval without keyword.
