<p>At least two microcomputers are provided for the controlling operation of an automatic vending machine, which are connected by signal wires of a number selected from one to four w.r.t. each other. One of the microcomputers is a main microcomputer, while the other is a submicrocomputer. The submicrocomputer performs the controlling operation on the restricted block functions of the automatic vending machine, while the main microcomputer transmits control codes to the submicrocomputer through the signal wire to control the operation of it, and controls the automatic vending operation while serially transmitting or receiving the necessary data.</p> |
