Description of the invention (/) The present invention is generally related to a point of sale (POS) system, and more particularly an integrated input device for a POS system. Any combination of at least two sets of input functions is combined into a set of integrated units. Point of sale systems are well known in the prior art. Generally speaking, in a group of point-of-sale systems, multiple array peripherals, such as credit card readers' barcode scanners, keyboards, smart card readers, and the like must interface with each other and with a group of regional POS computer terminals interface. For example, the most commonly used POS components in a set of POS systems include: cash dispenser-interface with receipt printer, parallel port, or serial port. Receipt printer-interface with parallel port or serial port = monitor and computer-interface with VGA port. Customer side display-interface with parallel port or serial port. POS keyboard-interface with keyboard or serial port "Credit card reader-interface with keyboard, parallel or serial port. Bar Code Reader-Interface with keyboard or serial port. Mouse board-interface with serial port. Smart card reader-interface with parallel or serial port. Interfacing with multiple sets of peripheral components requires numerous external cables to form the interface. The interconnection of sales points in the conventional POS system increases the cost and complexity of the system while reducing the reliability of the system. A further obstacle to component integration is the mismatch in the actual dimensions of the various components. For example, combining a large laser barcode scanning machine with a keyboard is not practical. Therefore, it is necessary to use the matched data format to integrate components to minimize the number of interconnected cables, and to introduce space saving and reduce costs.

Any or all of the keys can be planned. In addition, the keyboard I includes a plurality of pointed holes 15 designed to accommodate pens or pencils, and a set of keyboard locks 16 that can be covered by a trademark when not in use. The keyboard additionally includes four sets of electrical connections behind the keyboard i (Not shown) " especially a set of RJ11 connectors (keyboard ports), a set of PS2 DIN connectors (for downstream daisy-key components) 'set of' RS〗 32 connectors (output serial ports) And a set of USB (Universal Serial Bus Connectors connected to a computer). The barcode scanner 2 is advantageously configured to load one or two sets of logic control KB5 1 00 openings, which are The popular way is formed in area 17 to accommodate the scanner and is placed on the far right and left end of the keyboard, as shown in Figures la, 1b, and 1c. "In the barcode scanner module 2 and The simplest practical installation interface between the keyboards 1 is a set of rigid installation rigid interfaces.

Figure 4 shows a simplified block of a set of conventional electrical interfaces between keyboard 1 and barcode scanner 2 (or magnetic card reader 3, or smart card reader). Figure. In this simplified interface, it is assumed that keyboard 1 and barcode scanner module 2 (or magnetic card reader 3, or smart card reader) provide a set of keyboard embedded compatible with the keyboard input port of the POS system Interface "The integrated input device of the present invention includes a set of control circuits 8 between the barcode scanner module 2 (or magnetic card reader 3, or smart card reader) and the keyboard bus of the POS system. Specific hardware and methods to eliminate bus competition, including circuits that can be advantageously employed to construct the control circuit 8 are further detailed in the accompanying Appendix A. The control circuit 8 is proposed to be coupled to a set of first An electric control open leg 9 and a set of second electric control switches 1 0. The first electric control switch 9 and the second electric control switch 10 each respond to a control signal received from the control circuit 8 and selectively turn the keyboard 1, Scanner module 2.

The control circuit s monitors the activity of the barcode scanner 2 (or the magnetic card reader 3 or the smart card reader). When the barcode scanner module 2 (or magnetic card reader 3 or smart card reader) has data transmitted to the keyboard bus, the control circuit 8 checks the action of the keyboard 1. If there is no activity, the control circuit 8 sets the first electrical control switch 9 and the second electrical control switch 10 to connect the barcode scanner module 2 (or magnetic card reader 3, or smart card reader) to the keyboard bus. " If the control circuit 8 determines that the keyboard 1 is in a program that communicates with the system keyboard bus > the control circuit 8 retains data from the barcode scanner module 2 (or magnetic card reader 3, or smart card reader) until The keyboard 1 finishes the current data transmission.
