Abstract

A checkout system including a rotating barcode reader. In an example embodiment, the checkout system includes a base, a platform rotatable with respect to the base, a substantially circular top plate mounted to the platform including a window; and a barcode reader on the platform adjacent the window. The substantially circular top plate and the barcode reader are rotatable with the platform.

Description

BACKGROUND

The present invention relates to checkout systems, and more specifically to a checkout system including a rotating barcode reader.

Fixed barcode readers are mounted within a checkout counter. The footprint or mounting aperture of fixed barcode readers is rectangular. When equipped with built-in scales, fixed barcode readers include rectangular weigh plates.

One type of fixed barcode reader can read barcodes presented on any of a plurality of sides of an item, thereby minimizing the need for an operator to orient an item with respect to the barcode reader during scanning. This type of barcode reader may include a dual-aperture barcode reader, with a horizontal window and a vertical window. The horizontal window may be substantially flush with the surface of the checkout counter. The vertical window may be located within a tower portion rising from the surface of the checkout counter.

In some checkout environments, it would be desirable to re-configure an assisted-service checkout counter for self-service operation, or vice versa, without asking customers to switch sides or redirect customer traffic past the checkout counters. Since the vertical window of a dual-aperture barcode reader must face the operator in order to easily scan items, checkout systems which contain dual-aperture barcode readers offer retailers very little flexibility for reconfiguring their stores with more or less of either assisted-service and self-service checkout systems.

U.S. Pat. No. 6,286,758 assigned to the assignee of the present invention discloses an example checkout system including a drawer containing a pivot. A barcode reader is mounted to the pivot. Reconfiguration of the checkout system requires that the drawer be pulled out, the barcode reader rotated, and the drawer be pushed in.

It would be desirable to provide a checkout system which is more easily reconfigured for either assisted-service or self-service operation.

SUMMARY

In accordance with the teachings of the present invention, a checkout system including a rotating a barcode reader is provided.

In an example embodiment, the checkout system includes a base, a platform rotatable with respect to the base, a substantially circular top plate mounted to the platform including a window; and a barcode reader on the platform adjacent the window. The substantially circular top plate and the barcode reader are rotatable with the platform.

DETAILED DESCRIPTION

Referring now to FIGS. 1A-1B and 2A-2B, an example checkout system 10 includes a checkout stand with a receiving portion 12, a bagging portion 14, and a scanning portion 16.

Receiving portion 12 includes shelf 20 where purchased items may be placed.

Bagging portion 14 may include a conveyor 22 for conveying purchased items to a location for bagging.

Scanning portion 16 includes terminal 30, terminal interface 32, and barcode reader 34. Scanning portion 16 additionally includes scale 44, which may be part of barcode reader 34 or separate from barcode reader 34.

Terminal 30 may be located within scanning portion 16. Terminal 30 is preferably connected to a store network.

Example terminal interface 32 couples to terminal 30 and includes a touch screen 36 and a card reader 38 for reading loyalty and payment cards.

Example checkout system 10 may include additional peripherals, such as a cash drawer, a receipt printer, a signature capture pad, and a customer display for assisted-service operation and a currency and/or coin acceptor and/or dispenser, a receipt printer, and a signature capture pad for self-service operation.

With reference to the embodiment of FIGS. 1A-1B, terminal interface 32 may be removably mounted to the top surface of scanning portion 16.

In another example, terminal interface 32 may be mounted to a ring 40 separate from weigh plate 50. Ring 40 has substantially circular inner and outer edges and may rotate with weigh plate 50 (e.g., mounted to platform 82—FIG. 3) or be attached to weigh plate 50. Alternatively, ring 40 may be free to rotate separately. In such an example, terminal interface 32 is rotated by rotating ring 40. Any other peripherals, such as card reader 38, mounted to terminal interface 32 and/or ring 40 also rotate.

Scale 44 may include one or more load cells, such as planar load cells.

With reference to the embodiment of FIGS. 2A-2B, terminal interface 32 may be mounted to barcode reader 34.

In other examples, terminal interface 32 may be mounted elsewhere and reconfigured for assisted-service or self-service operation in other ways.

Example barcode reader 34 may be a laser scanner, imaging scanner, or any combination thereof.

With reference to the embodiment of FIGS. 1A-1B, weigh plate 50 is substantially circular in shape and contains window 52. Example window 52 is rectangular in shape, but may be any other shape, such as circular. Window 52 may be made of a scratch-resistant glass. Weigh plate 50 may be made of stainless steel and may be substantially flush with the top surface of scanning portion 16. Weigh plate 50 may additionally include an edge lip to constrain liquids and/or debris.

With reference to the embodiment of FIGS. 2A-2B, weigh plate 58 is substantially circular in shape and contains window 54 and aperture 60.

The example barcode reader 34 may include a dual-aperture bar code barcode reader with a substantially horizontal window 54 and a substantially vertical window 56. Substantially horizontal window 54 may be part of weigh plate 58 and be rectangular in shape.

Substantially vertical window 56 is part of a raised tower portion that extends through aperture 60 in weigh plate 58 above the top surface of scanning portion 16. Substantially vertical window 56 faces an operator during scanning.

Weigh plate 58 may be made of stainless steel and may be substantially flush with the top surface of scanning portion 16. Weigh plate 58 may additionally include an edge lip to constrain liquids and/or debris.

Example checkout system 10 includes a store operator side 70 and a customer side 72. During assisted-service operation, terminal interface 32 faces store operator side 80. A store operator scans items selected for purchase by a customer and completes payment for the items, for example, using card reader 38. During self-service operation, terminal interface 32 faces customer side 72. A customer scans items selected for purchase and completes payment for the items, for example, using card reader 38.

To facilitate a change in operation of checkout system 10 between assisted-service and self-service modes, barcode reader 34 rotates to positions for the corresponding mode of operation. Peripherals mounted to barcode reader 34 and/or fill plate 60 rotate with barcode reader 34 and fill plate 60.

Depending on mounting configuration, terminal interface 32 may rotate with barcode reader 34 or be positioned separately, for example, via ring 40. Peripherals mounted to terminal interface 32, such as card reader 38, reposition with terminal interface 32.

With reference to FIG. 3, an example mounting assembly 80 containing barcode reader 34 and scale 44 includes platform 82. Platform 82 rotates between an assisted-service position and a self-service position during configuration changes.

Barcode reader 34 is mounted to platform 82 and rotates with platform 82. The example barcode reader 34 is a single-aperture barcode reader, though a multi-aperture barcode reader may also be mounted to platform 82 as in FIGS. 2A-2B.

Scale 44 includes planar load cells 84, which are mounted to platform 82. Posts 86 are mounted to planar load cells 84 and support weigh plate 50 above barcode reader 34. Planar load cells 84, posts 86, and weigh plate 50 rotate with platform 82.

In one example embodiment, weigh plate 50 includes an indent 90 near its outer edge. A torque applied to weigh plate 50 at indent 90 causes platform 82 to rotate about its centerline.

With reference to FIG. 4, platform 82 is supported by a stationary base 96. In one example embodiment, platform 82 and base 96 are separated by ball bearings, which allow platform 82 to freely move. Aperture 94 along with a corresponding aperture in platform 82 provide access for cable runs to barcode reader 34, scale 44, and terminal interface 32. The apertures are centrally located to minimize cable movement and twisting during rotation of platform 82.

Platform 82 may include a detect 98 which engages corresponding latches in the mounting recess 100 (FIG. 5) at assisted-service and self-service positions to prevent rotation of platform 82 at times other than reconfiguration.

With reference to FIG. 5, scanning portion 16 includes circular aperture 102 defining mounting recess 100 into which assembly 80 is inserted during installation. A predetermined distance separates weigh plate 50 from aperture 102.

In operation, an operator applies a finger or other tool to indent 90 to rotate platform 82 about its centerline from a self-service operating position to an assisted-service operating position, and back again. The angle between the two positions may be about 180 degrees. At the self-service operating position, a self-service checkout transaction using the barcode reader is performed by a customer. At the assisted-service operation position, an assisted-service checkout transaction is performed by an operator. Advantageously, the operator may rotate platform 82 without removing barcode reader from the checkout counter.

Although particular reference has been made to certain embodiments, variations and modifications are also envisioned within the spirit and scope of the following claims.
