To easily exchange components without requiring the substantial reprogramming of a CUP even if these elements are exchanged with separate elements having various characteristics by converting function instructions to physical instructions in order to operate the operation components in accordance with desired operation sequence.

This device has the output operation components 22, 30, 25, 54, 92, 96, the input operation components 24 and the plural operation components selected from the combinations thereof and the central processing unit operatively linked to the operation components. The central processing unit includes the information relating to the desired operation sequence for the device. The information relating to the characters of the respective operation components is recorded in separate memory means 122, 130, 125, 154, 192, 196. The information relating to the desired operation sequence for the device is the type of the function instructions independent from the characters of the operation components and converts the function instructions to the physical instructions in order to operate the operation components in accordance with the desired operation sequence.
