Abstract
Abstract A totalizer for recording the income of a multiprice vending machine, the totalizer including a device to determine the value of the item selected, the fact that a sale was made, and a counter to total the value of all items selected. The totalizer preferably verifies the correctness of the value of the item selected to prevent erroneous counts and also preferably generates a coded output signal representing the price line of the vending machine providing information.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
213 words
A totalizer for use with a multi-price vending machine for vending items and having a plurality of price wires which carry a signal representing the value of an item selected by the user of the vending machine and a device for providing a control signal indicating the sale of the item, said totalizer comprising first means for respectively scanning said wires to detect a value of sale signal, second means for storing the value of sale signal detected, and third means responsive to the control signal for controlling the storage of the value of the sale signal in said second means, said first means comprises a data selector means coupled to said price wires, a first counter for providing signals to said data selector for causing same to scan said price wires, clock means for clocking said first counter, first storage means for storing the count of the first counter after a first detection of a value of sale signal by said data selector, and comparator means responsive to the count in said first counter after the second detection of a value of sale signal by said data selector and the count stored in said storage means for generating a comparison valid signal indicating valid valie value of sale signal has been detected.
