Keyboard for Windows-Based Terminals {KEYBOARD FOR WINDOWS BASED TERMINAL}

The present invention relates to a keyboard for a Windows-based terminal, and more specifically, to a Windows-based terminal equipped with a double-use board that provides a Windows Based Terminal (WBT) function used as a thin client. It's about the keyboard.

Personal computers are now an essential device in the office environment, but the initial purchase and operating costs are not enough to put a heavy burden on companies. In particular, it is expensive to introduce a new program, and when a failure occurs, computer managers must go to the site and perform repairs.

To overcome these problems, thin clients are emerging. Thin clients include Windows Based Terminal (WBT), NetPC (NC) and Network Computer (NC). .

However, NC using Java Applet has the disadvantage that all applications must be written again in Java, and some programs must be downloaded from the server to the client in the form of applets and executed on the client. In addition to increasing traffic, the client's own specifications must be advanced, so it's not a true thin client. Similarly, NetPC does not differ from a conventional PC because it is only a network based on a conventional personal computer. Therefore, the Windows-based terminal that is best suited for thin clients is leading the thin client market.

Unlike a conventional desktop computer, a Windows-based terminal is composed of an operating system and a minimum of computer resources without a storage device such as a hard disk or a CD-ROM drive. Tasks are performed on a server connected to a Windows-based terminal. It is displayed in a window-based terminal. In other words, a window-based terminal runs all applications on the server, and a client-based window-based terminal passes only mouse or keyboard input to the server. By using protocols such as Independent Computing Architecture, the protocols are delivered to clients, which not only increases network traffic, but also does not require advanced client specifications.

Windows-based terminals, by themselves, have greatly limited functionality, such as browsing the Internet, but when connected to a server, most computer operations are possible. Windows-based terminals have the advantage of significantly lower operating costs (TCO) with lower initial installation costs. This means that software upgrades and management can only be done on the central server, which can significantly reduce overall operating costs compared to desktop computers and server systems.

Such window-based terminals can be used in various offices such as banks, securities and insurance companies, small and medium businesses, SOHO, educational institutions such as schools or libraries, and specific content service networks.

However, the conventional window-based terminal is coupled to each peripheral device such as a keyboard, a mouse, and a speaker so that the window-based terminal is too cumbersome and complicated to have flexibility. Therefore, since the window-based terminal must be provided in each place where the window-based terminal should be used for the same or similar purposes, the cost is doubled, and when the WLAN is used, the fluidity of the used space of the WLAN is reduced It became a factor to make.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a keyboard for a window-based terminal that can increase the flexibility of the window-based terminal by integrating devices such as a double-use board, touch pad, speaker to the keyboard It is.

In addition, the disk insertion hole of the floppy disk drive is formed to be exposed to the rear or side of the keyboard for a Windows-based terminal. Thus, the user can perform the operation while reading and storing the data stored in the floppy disk through the keyboard for the Windows-based terminal.

Each component provided on the lower plate may be attached to the upper plate 100a.

As shown in FIG. 3D, the double utility board 150 includes a power input code 152 and a plurality of data input / output ports that receive power from the outside. The data input / output port is for providing scalability by inputting / outputting data or connecting the double-use board 150 and a peripheral device. The PS / 2 port 154, the USB port 156, the COM port 158, and the LPT port ( 160, a sound port 162, a monitor connection port 164, and wired / wireless communication ports 166 and 168. Each port is formed to be exposed to the front of the keyboard 100 for the window-based terminal. In addition to the temporary port illustrated in FIG. 3D, the double utility board 150 may further include another port if necessary.

Of these, various peripherals are connected to the USB port 156 and may connect an external hard disk or an external floppy disk drive. Thus, the user can read, store and use external data via an external hard disk or external floppy disk drive.

The sound port 162 is a port connected to an external speaker when the external speaker is to be used in addition to the speaker 140 provided in the keyboard 100 for a window-based terminal. The sound port 162 is provided in the sound processing unit in the double-use board 150. Port.

In addition, the monitor connection port 164 is a port for data transmission between the double utility board 150 and the monitor 200 is connected by the input terminal and the cable of the monitor 200. The monitor connection port 164 is provided with a display processing unit of the double utility board 150 and inputs display data processed by the display processing unit to the monitor 200.
