Abstract

Identical products are stored in a plurality of columns. Dispensing product numbers of the respective columns are calculated in accordance with the numbers of products stored in the respective columns. The calculated dispensing product numbers are set in corresponding counters. The counters are decremented every time a product or products is/are dispensed from each column. When all the counts of the counters are set to "0", the calculated dispensing product numbers are set again in the corresponding counters, and the above operation is repeated, thereby dispensing the products on the FIFO basis.

Claims

1. An automatic vending machine for dispensing products in rotation from a plurality of columns, comprising:

setting means for respectively setting product numbers of said plurality of columns in accordance with the numbers of products stored in said plurality of columns;

dispensing pattern calculating means for calculating dispensing product numbers of said plurality of columns in accordance with the product numbers set by said setting means;

down counters which are preset with values respectively corresponding to the dispensing product numbers calculated by said dispensing pattern calculating means and which are respectively decremented every time the products are dispensed from said plurality of columns;

discriminating means for discriminating one of said down counters which has a maximum value;

dispensing means for dispensing the products from a column corresponding to one of said down counters which is discriminated to have the maximum value by said discriminating means;

detecting means for detecting zero counts of all of said down counters; and

resetting means for resetting the values calculated by said dispensing pattern calculating means in said down counters to zero in response to an output from said detecting means.

2. A machine according to claim 1, wherein said discriminating means generates discrimination signals in accordance with a priority order when a plurality of said down counters have the maximum value.

3. A machine according to claim 1 or 2, further comprising sold-out detecting means provided for each of said plurality columns, said down counters being reset to zero when said sold-out detecting means detects a sold-out state.
