ABSTRACT:
An input device for a data processor is provided with an input circuit having input keys to designate two or more kinds of functions, an operation unit to perform operational processing in accordance with function inputs from the input circuit, an auxiliary memory to store therein a state of the operation unit, and a memory for a function table wherein the function to be carried out by the operation unit and the state of the operation unit, to which it is to be shifted after completion of the functions, have been previously written in an address to be determined by combination of the input key and the stored contents of the auxiliary memory. One of the two or more kinds of functions assigned to an input key is selectively introduced into the operation unit by the abovementioned input key.
