## Title
Computer peripheral with integrated printer and bar code reader

## Abstract

A computer peripheral with integrated printer and bar code reader which saves space on countertops. The computer peripheral includes a printer, including a housing, a bar code reader in the housing, and control circuitry in the housing for facilitating communication of data between the printer and a computer and between the bar code reader and the computer over a single cable.

## Background
BACKGROUND OF THE INVENTION
The present invention relates to computer peripherals used in retail establishments, and more specifically to a computer peripheral with integrated printer and bar code reader.
In virtually all store formats, the POS solution includes various displays, a keyboard, printer, and scanner. In certain retail formats, such as department stores and specialty stores, typical transactions consist of a small number of items. Therefore, large scanners are unnecessary. A small “presentation” scanner is typically used.
However, a presentation scanner can often become a nuisance—“always in the way” of the cashier or constantly getting “buried” under merchandise. Therefore, it would be desirable to provide a computer peripheral with integrated printer and bar code reader to reduce clutter and cabling and to improve general productivity at the checkout station.
SUMMARY OF THE INVENTION
In accordance with the present invention, a computer peripheral with integrated printer and bar code reader is provided.
A computer peripheral with integrated printer and bar code reader which saves space on countertops. The computer peripheral includes a printer, including a housing, a bar code reader in the housing, and control circuitry in the housing for facilitating communication of data between the printer and a computer and between the bar code reader and the computer over a single cable.
It is accordingly an object of the present invention to provide a computer peripheral with integrated printer and bar code reader.
It is another object of the present invention to provide a computer peripheral with integrated printer and bar code reader in order to increase available counter space and consolidate cabling.



BRIEF DESCRIPTION OF THE DRAWINGS
Additional benefits and advantages of the present invention will become apparent to those skilled in the art to which this invention relates from the subsequent description of the preferred embodiments and the appended claims, taken in conjunction with the accompanying drawings, in which:
FIG. 1 is a block diagram of a transaction system with the peripheral of the present invention; and
FIG. 2 is a perspective view of one example implementation of the peripheral.



DETAILED DESCRIPTION
Referring to FIG. 1, transaction system 10 primarily includes transaction terminal 12, peripheral 14, display 16, keyboard 18, and card reader 20.
Transaction terminal 12 determines information about purchased products and processes payment. Transaction terminal 12 includes universal serial bus (USB) controller 22 for communicating with peripheral 14, display 16, keyboard 18, and card reader 20. Other input/output controllers and communication techniques are also envisioned, such as RS-232, RS-485, Firewire, and Bluetooth and other wireless techniques.
Peripheral 14 includes bar code reader 30 and printer 32, both in the same housing 36.
Bar code reader 30 is preferably a charge coupled device (CCD) scanner, or other type of imaging scanner.
Printer 32 may include an NCR 7167 multi-function printer.
In a preferred embodiment, housing 36 is the housing of printer 32. Bar code reader 30 is small enough to fit inside of housing 36.
Peripheral 14 also includes USB hub 34 for connecting bar code reader 30 and printer 32 to transaction terminal 12. Other connection methods are also envisioned when other types of communication techniques are used.
Display 16 may include a cathode ray tube (CRT) or liquid crystal display.
A touch screen may replace keyboard 18 and display 16.
Card reader 20 reads payment cards, such as credit, debit, and smart cards. Card reader 20 may also read loyalty cards.
Transaction system 10 may include additional peripherals as necessary to accomplish its purpose.
Turning now to FIG. 2, an example peripheral 14 is shown. Peripheral 14 is based on the NCR 7167 multi-function printer.
Printer 32 is located in the top rear section. Printer 32 is a thermal printer for printing receipt 46.
Bar code reader 30 may be located in the top front section of housing 36, or in any other location where bar code reader 32 will not interfere with other components in peripheral 14. In the example peripheral of FIG. 2, bar code reader 30 is mounted to the top cover portion of housing 36. Bar code reader 32 is accessible through an opening in the front surface of the top cover portion. Bar code reader 30 may also be located in the top or side surfaces of housing 36.
Bar code reader 32 functions as a presentation scanner. A checker presents bar code 52 of item 50 to bar code reader 30.
Peripheral 14 also includes an impact printer 42 for printing information on the backs of checks passed through magnetic ink character recognition (MICR) reader 40 on slip table 44.
Peripheral 14 has several advantages. It reduces space and clutter on the countertop and reduces the opportunity for a separate bar code reader to “get lost” under merchandise, papers, etc. It reduces the possibility of a separate scanner to be dropped and broken. It leverages the proximity of the printer in most checkout stands to put the bar code reader in a convenient, predictable location. It improves reliability since a single cable to transaction terminal 12, instead of separate cables, is required. Finally, it reduces the number of input/output connections required by transaction terminal 12, so it potentially helps reduce the size and cost of transaction terminal 12.
Although the present invention has been described with particular reference to certain preferred embodiments thereof, variations and modifications of the present invention can be effected within the spirit and scope of the following claims.

## Claims

1. A computer peripheral comprising:
a peripheral housing for containing only two normally separately housed peripherals for saving space at a checkout station including a receipt printer and a bar code reader; and
control circuitry in the housing for facilitating communication of receipt data reflecting a sale of products between the printer and a separately housed controlling transaction computer at the checkout station and bar code data from the products between the bar code reader and the separately housed controlling transaction computer over a single cable during the sale of the products completed by the transaction computer.
