Abstract
Abstract A checkout counter having an optical scanning unit located therein and includes a surface portion comprising a scale apparatus which includes a transparent portion enabling scanning beams projected by the optical scanner unit to be transmitted through the scale apparatus for reading a coded label on a merchandise item positioned on the scale apparatus. The scale apparatus generates data signals representing the weight of the merchandise item which are then transmitted to a processor means which also receives data signals from the scanning unit identifying the merchandise item. The processor means will generate the price of the merchandise item using the data signals received. The price of the merchandise item is then displayed on a display unit and printed by a printing unit on a customer's receipt.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
340 words
A checkout system for checking merchandise items having a coded label affixed thereto identifying the merchandise item comprising; a checkout counter having a first top surface for supporting a merchandise item thereon; a cover assembly positioned on an end portion of the checkout counter having a second top surface coplanar with the first top surface of the checkout counter, said second top surface having an aperture therein; optical scanning means positioned in the end portion of the checkout counter adjacent said cover assembly for projecting scanning light beams through said aperture for scanning a coded label on the merchandise item and generating first data signals identifying the merchanise item; a first support member mounted on the end portion of the counter between the cover assembly and the optical scanning means; a first window member mounted in said first support member in registry with the optical scanning means and said aperture for enabling the scanning light beams of the optical scanning means to be projected through said aperture; signal generating means including a load beam cell which includes a first cantilever support member secured to said first support member and a second cantilever member secured to said first cantilever support member; a second support member secured to said second cantilever support member and engaging said cover assembly; strain gauge means secured to said cantilever support member for generating signals in accordance with the moving of said cover assembly whereby the positioning of a merchandise item on the cover assembly results in the moving of the first and second cantilever support members enabling the strain gauge means to output second data signals representing the weight of the merchandise items; processing means connected to said optical scanning means and said signal generating means for generating third data signals representing the price of the purchased merchandise items in response to receiving the first and second data signals; and display means controlled by said processing means for displaying the price of the purchased merchandise item in response to the generation of said third data signals.
Claim 2
Dependent Claim
340 words
A checkout system for checking merchandise items having a coded label affixed thereto identifying the merchandise item comprising; a checkout counter having a first top surface for supporting a merchandise item thereon; a cover assembly positioned on an end portion of the checkout counter having a second top surface coplanar with the first top surface of the checkout counter, said second top surface having an aperture therein; optical scanning means positioned in the end portion of the checkout counter adjacent said cover assembly for projecting scanning light beams through said aperture for scanning a coded label on the merchandise item and generating first data signals identifying the merchanise item; a first support member mounted on the end portion of the counter between the cover assembly and the optical scanning means; a first window member mounted in said first support member in registry with the optical scanning means and said aperture for enabling the scanning light beams of the optical scanning means to be projected through said aperture; signal generating means including a load beam cell which includes a first cantilever support member secured to said first support member and a second cantilever member secured to said first cantilever support member; a second support member secured to said second cantilever support member and engaging said cover assembly; strain gauge means secured to said cantilever support member for generating signals in accordance with the moving of said cover assembly whereby the positioning of a merchandise item on the cover assembly results in the moving of the first and second cantilever support members enabling the strain gauge means to output second data signals representing the weight of the merchandise items; processing means connected to said optical scanning means and said signal generating means for generating third data signals representing the price of the purchased merchandise items in response to receiving the first and second data signals; and display means controlled by said processing means for displaying the price of the purchased merchandise item in response to the generation of said third data signals.
Claim 3
Dependent Claim
36 words
The system of claim 1 which further includes stop means secured to said first support member and extending in a direction towards said third support member for limiting the downward movement of said third support member.
Claim 4
Dependent Claim
41 words
The system of claim 2 which further includes: guide means secured to said first support member; and receiving means secured to said plate member for receiving said guide means upon the positioning of said plate member on said first support member.
Claim 5
Dependent Claim
42 words
The system of claim 3 which further includes a deflector member secured to the bottom edge of said first support member for deflecting liquids directed towards said first support member by said channel to a position away from said first support member.
Claim 6
Dependent Claim
97 words
The system of claim 1 in which said cover assembly includes: a first cover member having a top surface portion in which is located said aperture in registry with said optical scanning means and a plurality of depending feet members; a stiffener member secured to said cover member for increasing the rigidity of said cover member; and a plate member having a plurality of mounting apertures located therein in registry with said depending feet members whereby the cover member is mounted on said plate member by the positioning of said depending feet members within said mounting apertures.
Claim 7
Dependent Claim
50 words
The system of claim 5 which further includes a second window member mounted in said second support member and in registry with said first window member and said optical scanning means whereby the optical scanning means will project scanning beams through said first and second window members and said aperture.
Claim 8
Dependent Claim
100 words
The system of claim 6 which further includes: a third support member positioned on said first support member, said third support member having a top surface portion which is coplanar with the top surface portion of said first cover member; means securing said third support member to said first support member; and the top surface portions of said cover member and said third support member includes an edge portion forming a channel therebetween extending to a position adjacent said first support member enabling liquids spilled on said cover member and said third support member to be removed from said members.
Claim 9
Dependent Claim
47 words
The system of claim 7 which further includes a raised clamp member secured to said third support member and extending along the edge of said first window member for preventing liquids directed onto the third support member by said channel from spilling onto the first window member.
