Abstract
A control system for an automatic vending machine is adapted to set operating parameters such as the selling prices of various commodities. The system includes a microprocessor, associated memory, push-button switches, displays and a control program. For setting the price of a particular commodity the system responds to repeated actuation of certain switches and sequentially increments the values of a particular operating parameter stored in memory and displayed on the display, so that the value of a particular operating parameter can be changed without directly inputting data representing the desired value of the parameter. The operating mode of the machine is changed in a similar manner. The system reduces the number of switches required to change parameter values.
