Self-serve checkout system
First Claim
1. A self-service checkout system comprising:
- (a) a first stationary structural member intended for checkout use by a customer;
(b) bar code reader means and first scale means mounted in said first stationary structural member such that said bar code reader means does not make contact with the active elements of said first scale means but that said bar code reader means is mounted less than one meter away from said first scale means;
(c) said bar code reader means generating a first signal indicative of the product code of a product whose bar coded label has been read by said bar code reader means;
(d) bag holding means mounted upon said first scale means;
(e) said first scale means generating a second signal indicative of the weight present on said first scale means;
(f) first user input means mounted in said first stationary structural member generating a third signal indicative of the particular first user input means device selected;
(g) second scale means mounted in said first stationary structural member such that the top exposed surface of said second scale means defines an area where customers will temporarily deposit products without valid bar coded labels and where said second scale means generates a fourth signal indicative of the weight thereon;
(h) video sensor means mounted in a video sensor movement means above said first scale means and above said second scale means where said video sensor movement means can selectively move said video sensor means so as to view an image of the top exposed surface of the said second scale means or to view an image of the surface of the said first scale means;
(i) said video sensor means generating a fifth signal indicative of the image said video sensor means is currently viewing;
(j) first user display means mounted in said first stationary structural member;
(k) a second stationary structural member intended for supervisory use by a supervisory employee;
(l) second user display means mounted in said second stationary structural member where said second user display means receives said fifth signal and said second user display means displays an image corresponding to said fifth signal;

(q) said controller means sending a third controller signal to said video sensor movement means where said video sensor movement means moves the said video sensor means corresponding to the said third controller signal;
(r) product lookup table means attached to said controller means;
(s) said controller means upon receiving the first signal from said bar code reader means, sending a signal indicative of the first signal to said product lookup table and receiving in return a stored weight signal from said product lookup table indicative of the weight of the product whose bar code has just been read by said bar code reader means where said controller means compares the said stored weight signal with the increase in the second signal, indicative of the increase in weight on the said first scale means, being received from the said first scale means and where there is no valid correspondence between said stored weight signal and the increase in the second signal, said controller means sends a first controller signal to said first user display means advising the user of the lack of such valid correspondence; and
(t) said controller means upon receiving the third signal from the said first user input means indicative of a product without a valid bar code, sending a third controller signal to said video sensor movement means such that said video sensor movement means moves the said video sensor means such that the said video sensor means views the surface of the said second scale means and thus the image of the surface of the said second scale means is indicated by the fifth signal and is thus displayed on the said second user display means, and sending a second controller signal to the said third user display means, and upon receiving a valid sixth signal from the said second user input means sends a first controller signal to said first user display means advising the user to transfer the contents on the said second scale means to the said first scale means and then verifies that the increase in weight indicated by the increase in the second signal is equal to the previous value of the fourth signal indicating the weight previously on the said second scale means.

Abstract
A self-serve checkout system which consists of a self-service checkout station containing a video camera unit which generally views a first scale where bar coded products are deposited and which pivots to view a second scale where products without bar coded labels are initially deposited. The video camera generates a signal received by a display in a supervisor station which allows a supervisory employee to approve non-bar coded products and to survey in general other products deposited on the first scale. A plurality of self-service checkout stations are selectively connected to a singular supervisor station by a switching unit. The self-service checkout stations contain angles or active surfaces to prevent deposition of articles for later fraudulent removal. The self-service checkout stations contain receipt printers, magnetic payment card readers and coupon acceptors to further reduce the time the supervisory employee must spend on each order.
