Abstract

A keyboard device with extended function keys is composed of a keyboard and multiple extended function keys at right side of keyboard, which are associated with additional row or column lines connected to specific I/O lines of microprocessor in internal circuit of keyboard and matched with original keyboard scan matrix to form 9X 16 new scan matrix, and can be used by operator to directly execute window (Windows) system application program to control the functions of multimedia peripheral equipment and to observe its effect on display.

Description

Keyboard device with extended function keys

The utility model relates to a keyboard device for expanding function keys, in particular to a keyboard for an expandable multimedia peripheral device (such as a CD player). (Windows) system application program execution, so that the operator can directly manipulate the functions of the multimedia peripheral equipment on the keyboard, and observe the effect on the screen of the monitor; or make these function keys cooperate with a macro procedure (Marco Procedure) to Complete a predetermined program control or other functions.

Although there are 128 default codes that can be set on the standard keyboard of the existing general computer system (such as: IBM), yet, after deducting the number of keys and system command codes used in various languages, the most usable key codes The number is only 8, so the purpose of the extended function key (HotKey) is virtually limited.

In addition, generally on a multimedia peripheral device (such as a CD player), if you want to control the functions of the device (such as: PLAY, ←, →, Volume... etc.), you need to directly operate on the device, and you cannot use it on the existing Control it from the keyboard and observe its effects directly from the monitor screen.

In view of this, the inventor of the present utility model has finally developed and designed a keyboard device with extended function keys based on such shortcomings and relying on years of experience in manufacturing related products, through careful observation and research.

The purpose of this utility model is to provide a keyboard device for expanding function keys, which is embedded with a plurality of (1-15) enlarged function keys (Hot Keys) on the right side of the keyboard. Corresponding to the added row or column lines in the newly scanned matrix of internal circuits.

Another object of the present utility model is to provide a keyboard device with expanded function keys, which directly defines expanded function keys on undefined matrix points in the original scanning matrix.

The purpose of this utility model is achieved in that a keyboard device with expanded function keys is provided, comprising: a keyboard and a plurality of expanded function keys embedded on the keyboard; The specific I/O line of the microprocessor of the structure matches the row or column line corresponding to the expanded function key; the original keyboard scan matrix and the added row or column line form a new scan matrix. If the number of keys defined by the original scanning matrix keyboard is relatively small, these function keys can be directly defined on the undefined matrix points in the original scanning matrix, so that it is not necessary to expand the row or column lines connected with the I/O lines.

The utility model device has the advantage that the operator can directly use these function keys to execute the Windows (Windows) system application program to manipulate the functions of the peripheral equipment on the keyboard, and observe its effect on the screen of the display; in addition, the described Function keys can also cooperate with a macro procedure (MarcoProcedure) to complete predetermined program control or other functions.

In order to further understand and understand the purpose, shape, structure or device features and efficacy of the present utility model, the embodiments are described in detail below in conjunction with the accompanying drawings, wherein:

FIG. 1 is a schematic diagram of a keyboard of the present invention.

Fig. 2 is a connection diagram of the internal circuit structure of the keyboard of the present invention.

Please refer to a kind of " keyboard of expanded function key " of the present utility model shown in Fig. 1, it comprises components such as a keyboard 1 and a plurality of enlarged function keys 2.

On the right side of keyboard 1, a plurality of (1-15) function keys (Hot Key) 2 are embedded, and it comprises: "CD Player" 21, "Play" 22, "←" 23, "→" 24, "Volume" 25... etc. These function keys 2 correspond to the added row or column line 111 connected to the microprocessor 11 specific I/O line of the internal circuit structure of the keyboard 1, and make it match the original keyboard scanning matrix (generally One 8 * 16Scan Matrix) 12, to form a new scanning matrix of one 9 * 16, as shown in Figure 2, to realize the purpose of expanding the function key (Hot Key) (the number of these expandable function keys can be according to user's needs To design, if more than 16, in this way, the keyboard scanning matrix can be a new scanning matrix of 9*16, 10*16, 11*16...etc.).

In this way, these expanded function keys 2 can be executed through the Windows (Windows) system application program, so that the operator can directly manipulate the functions of the multimedia peripheral device (such as a CD player in the embodiment of the present invention) on the keyboard 1. , and its effect can be observed on the screen of the monitor.

When the operator presses the function key 21 of "CD Player" on the keyboard, the Windows system application program can scan and intercept (Hook) the operator's internal code (Scancode) of "CD Player" pressed on the keyboard, and judge the internal code ( Scan Code) is a function key code (Hot Key Code)?

If the internal code (Scan Code) judges that the function key 21 of "CD Player" is indeed the function key pressed by the operator, then the Windows system application program will substitute the WinExec0 function provided by the Windows API into the file location of "CD Player" The path and application program CDPLYER.EXE (included in Windows 95 Bundle With Windows 95) file name parameter, like this, this " CDPlayer " promptly is started, and its control panel can appear on the screen of display immediately.

Now, if the operator presses the "Play" function key 22 of "CD Player", according to the above-mentioned action, the window system application program will convert this "Play" function key code into the keyboardStroke (keystroke) of Ctrl+P, and Release this information back to the window system, and after the CD Player receives it, it will start to execute the "Play" action.

As mentioned above, it is only a preferred embodiment of the present utility model, but the structural features of the present utility model are not limited thereto, and any person familiar with the technology in the field of the present utility model can easily consider Changes and modifications all belong to the scope specified by the appended claims of the present utility model.

Claims (2)
