TWI271639B - Computer ten-key pad and its key code control method - Google Patents

Abstract

A computer ten-key pad and its key code control method are disclosed. The ten-key pad gives up an original ""Num Lock"" key and uses a newly defined N-mode key and an A-mode key instead. After the newly defined N-mode key or the A-mode key has been pressed, the ten-key pad enters a status of outputting ""numbers"" or ""directions"" without influencing a computer system and a ""Num Lock"" status existing in other keyboards. The above N-mode key is further configured with a special key for a specific character, for outputting ASCII by means of a single key.

Description

127 1639 Case No. 90132689 V. Description of the Invention (1) The present invention relates to a computer numeric keypad and a keyboard code control method thereof, in particular, an innovative input process through a keyboard code and a skirt thereof to solve the problem that the digital keyboard needs to be continuously switched. It is inconvenient and can output special characters in a single button mode. Press, the general notebook computer and the keyboard of the desktop computer are slightly different. In order to meet the operational requirements, the notebook computer sometimes needs to add an auxiliary digital keyboard (TEN-KEY PAD). For example, when using a notebook computer and often using a numeric key, you will need to add a separate TEN_KEY PAD, which is convenient to use. As shown in Fig. 1, the existing TEN-KEY PAD 10 button generally combines two functions of π number π key and π direction π key, and the two functions are defined by a preset "Ni|l_L〇ck'' key 1 2 to switch, but when n Num Lock ', key 1 2 to switch, at the same time make the keyboard of the notebook computer (not shown) and the external TEN KEYPAD, the state of inm Lockn change together, this will cause When the user needs to use the English button, the keyboard of the notebook cannot be directly used to output the English button. The state of the "Num Lock1 must be changed again before the English button can be output. Otherwise, when the English button is output, the number, the button must be used again. At the same time, it is necessary to change the state of Num Lock again, which makes the user feel inconvenient and the control speed is slow. At the same time, there is no separate ''and'," etc. in the TEN-KEY PAD button. Symbol keys, although the standard keyboard has " + = " and " <, " buttons, but these buttons are composite two symbols

, 1271639 Case No. 90132689 曰倏月正正 _ 5, invention description (2) key and these buttons 'in the double-digit country (for example: Chinese, Japanese, Korean, etc.) will be used as Chinese phonetic symbols, Or Japanese Pinyin, when entering the Pinyin mode, it becomes neither "=" nor "" and so on, so it is not suitable for TEN-KEY PAD in simple digital application. The original standard keyboard or standard ΤΕΝ-ΚΕ γ PAD When the Nuin Lock LED is lit, the computer system will record. For example, if the keyboard or TEN-KEY PAD sends the keyboard code, the computer system will interpret the keyboard code as π 4” characters. When the Num Lock LED is off, the computer system will also record. If the keyboard or TEN-KEY PAD sends the π 4" keyboard code, the computer system will interpret the keyboard code as the "left arrow" function. The Num Lock LED will affect the interpretation of the keyboard code of the TEN-KEY PAD on the computer system side. And the Num Lock LED will be turned on or off by the computer system. The light or the gun light will be sent via the Keyboard Command. All standard keyboards or standard TEN-KEY PADs have been connected to the system, so use the standard practice (change the Num Lock LED status with the ''Num Lock' key). It is not possible to improve the current inconvenience of the TEN-KEY PAD. 0 For the above operation is inconvenient, although someone has designed another device with an internal drive (driver) to connect the software and system to TEN-KEY PAD "Num Lock", and can take the notebook Main keyboard cut

Correction 曰 __I27163 9 Case No. Qm .叩(9)q V. INSTRUCTIONS (3) An additional device involves a higher cost 1c design and the use of related magnetic plates is not ideal. The object of the present invention is to provide a computer TEN_KEY PAD and its keyboard code control method, which can solve the operation of TEN_KEY PAD as described above.

Nrnn Lock" has the disadvantage of constantly switching, and it can output a separate character such as "=" and", "..." with a single button of a special key. In order to achieve the above, the present invention discards the aforementioned "Num Lock" button, and uses two newly defined buttons, one of which is a digital mode button (N - m〇de KEY) 'the other is a direction mode button (A M〇de κΕγ), as long as the user presses any of the above new buttons, TEN ΚΕ γ pAD enters the output, the number π or ''direction'' key state, without affecting the computer system and the Num of other keyboards already present The Lock1' state, while the present invention changes the microprocessor (Micr〇Controller) firmware (FIRMWARE) to send the keyboard code as follows: In a possible embodiment of the invention, the microprocessor body is used to control two new definitions The process of sending the keyboard code of the button can be: 1) Before sending the keyboard code, the TEN-KEY PAD must first judge the current state of the computer system and the state of the TEN: the current TEN-KEY PAD; 2 If the current Num Lock, 'State', Num Lock' LED is ON and the MODE state of the TEN-KEY PAD of the present invention is N-MODE, the TEN-KEY PAD of the present invention sends a standard TEN-KEY keyboard. code;

If the current "Num Lock" status of the computer system is "Num Lock" LED OFF and the current MODE state of the TEN-KEY PAD of the present invention For A-MODE, the TEN-KEY PAD of the present invention sends a standard TEN-KEY keyboard code; 4. If the n Num Lock" state of the current computer system is n Num Lockn LED ON and the MODE state of the present TEN-KEY PAD For A-MODE, the TEN-KEY PAD of the present invention actively sends nSHIFTnMAKE CODE and then sends out the standard TEN-KEY keyboard code, and then actively sends out "SHIFT"BREAK CODE;

5. If the current state of the computer system is "Num Lockn LED OFF" and the MODE state of the TEN-KEY PAD of the present invention is N-MODE, the TEN-KEY PAD of the present invention actively sends out the nSHIFTnMAKE CODE and sends it again. The standard TEN-KEY keyboard code is then actively sent out, 'SHIFTnBREAK CODE. In another possible embodiment of the present invention, the microprocessor can send the keyboard code to control the two newly defined button processes:

3. If the MODE state of the TEN-KEY PAD of the present invention is currently N-MODE and
