<p>CONTROL DEVICE A price-setting control device for a vending machine can be used to set prices for a number of products and to store those prices in a memory. A decimal-type visual display selectively, hut simultaneously, displays a "line" number which is assigned to a given product plus the price set for that product. A line-selecting switch, rather than the customer-operated switches of the vending machine, is used to select the desired line number when the price, for the product corresponding to that line number, is to be set. mode-controlling data for the operation of the vending machine can be stored in selected locations within the memory; and the line-selecting switch plus a price-setting switch can be used to change that data.</p> |
