ABSTRACT:
A vending machine includes a plurality of selection switches corresponding to a plurality of items to be sold respectively, and in response to insertion of coins and the subsequent operation of any of selection switches, the item corresponding to the selection switch is vended. A RAM is installed associatedly with a microcomputer, and this RAM contains memory areas for storing the sales quantity and the sales amount on item basis, and these data are renewed at every vending. The RAM further contains a price memory area for storing the sales price of each item. When any of selection switches is operated in ready state of the machine, the price of the item corresponding to that selection switch is read from the RAM and is displayed on the inserted-amount display. Furthermore, when a selection switch is depressed in the state when the management mode is set up, the price of the item corresponding to that switch is displayed likewise. Moreover, in response to a selective operation of the selection switch, the sales quantity and the sales amount of an arbitrary item stored in each memory area of the RAM can be displayed in the management mode. When "continuous confirmation" command is given in the management mode, the price, sales quantity or the sales amount as described above can be displayed continuously in sequence for each item.
