Abstract

An integrated keyboard input device is disclosed, including those used for Point-Of-Sale system (POS). The standard keyboard is integrated with one or more optical scanners and any combination of other input peripheral devices, the optical scanner being mounted within the keyboard housing. The peripherals preferably can be selectively connected and disconnected from the keyboard and are interfaced with a keyboard wedge which allows each input peripheral to communicate directly to a computer in keyboard data format without requiring separate electrical connections to the computer.

Claims

1. A keyboard, the keyboard comprising:

a housing, the housing holding and partially enclosing keyboard keys, as well as electronic circuitry associated with the keyboard keys, the housing integrally and at least partially enclosing and supporting an optical scanner, whereby wiring is located internally between the housing and the optical scanner; and

an output, the output being responsive to the electronic circuitry associated with the keyboard keys, the output being further responsive to the optical scanner, and the output being able to be electrically coupled to a separately housed computer;

wherein the housing includes external dimensions, said external dimensions being substantially the same as external dimensions of at least one of a standard QWERTY computer keyboard and a standard point-of-sale (POS) computer keyboard.

2. A keyboard as defined in claim 1, further comprising a wedge circuit enclosed within said housing, the wedge circuit interfacing the optical scanner and the electronic circuitry associated with the keyboard keys with the computer, the wedge circuit avoiding bus contention between the electronic circuitry associated with the keyboard keys and the computer, the wedge circuit avoiding bus contention between the optical scanner and the computer.

3. A keyboard as defined in claim 1, wherein the optical scanner includes at least one of a laser scanner, a charge coupled device (CCD) scanner, an optical character recognition (OCR) scanner, and a light emitting diode (LED) scanner.

4. A keyboard as defined in claim 3, wherein the laser scanner includes at least one of a one-dimensional laser scanner, a two-dimensional rastering laser scanner, and an omni-directional laser scanner.

5. A keyboard as defined in claim 1, wherein the optical scanner includes a pivotable mounting, the pivotable mounting enabling the optical scanner to be rotated in at least one of three planes.

6. A keyboard as defined in claim 1, wherein the optical scanner includes a pivotable mounting, the pivotable mounting including a gimbal, the gimbal enabling the optical scanner to be positioned in at least one of three planes.

7. A keyboard as defined in claim 1, wherein the optical scanner includes a mounting cup, the mounting cup including a ball housing, the ball housing holding the optical scanner, the mounting cup enabling the optical scanner to be positioned in at least one of three planes.

8. A keyboard as defined in claim 1, further comprising a magnetic card reader and a wedge circuit, the wedge circuit being enclosed within said housing, the wedge circuit interfacing the magnetic card reader with the computer, the wedge circuit avoiding bus contention between the magnetic card reader and the computer, the magnetic card reader including an output able to be electrically coupled to the computer.

9. A keyboard as defined in claim 1, further comprising a smart card reader and a wedge circuit, the wedge circuit being enclosed within said housing, the wedge circuit interfacing the smart card reader with the computer, the wedge circuit avoiding bus contention between the smart card reader and the computer, the smart card reader including an output able to be electrically coupled to the computer.

10. A keyboard as defined in claim 1, further comprising a touch pad and a wedge circuit, the wedge circuit being enclosed within said housing, the wedge circuit interfacing the touch pad with the computer, the wedge circuit avoiding bus contention between the touch pad and the computer, the touch pad including an output, the output able being able to be electrically coupled to the computer.
