PURPOSE:To automatically set the number of the fullness of products at each column at the time of changing sales products. CONSTITUTION:The number of stocks 5A in a memory 5 is added/updated each time of the detection of a product input detection sensor 1 and subtracted/ updated each time of carrying-out the product. When a stock number zero clearing means 4A detects a sold-out switch 7, the number of stocks 5A is zero-cleared. Hereafter, the number of fullness 5B in memory 5 is updated to be equal to the number of stocks whenever the number of stocks 5A updates a maximum value after the zero clearing of itself by way of a fullness number arithmetic means 4B. |
