INSTRUCTION DESCRIPTION (丨) The present invention relates to a method for controlling the working state of an extended keyboard, in particular, a method for locking the working state of the extended keyboard differently from the computer keyboard without pre-hanging the driver, so as to lock all the typing actions as The method of typing numbers. The term "keypad" as used herein refers to a keypad that is additionally expanded by the notebook computer for easy typing of numbers (as shown in Figure 5). The reason why the notebook is equipped with an expansion keyboard is that it reduces the volume and reduces the number of keys on the keyboard. Therefore, the numeric keys on the keyboard are shared with other alphabet keys. If you need to type a number, use the "Shift" key. The shared number key is used to type a number. In this way, when the chance of inputting a number is small, the inconvenience is not significant. Once the user has to input a large number of numbers, for example, using EXECL or other software that has to input a large number of digits, the foregoing Imagine the inconvenience of using the "Shift" key plus the number keys. In order to solve the above problems, an expansion keyboard has appeared. When a notebook computer user has a large number of input numbers, the expansion keyboard is connected with the notebook computer to facilitate the user to input numbers. The aforementioned expansion keyboard (see the sixth figure) is actually like the 1 7-key numeric keypad on the right hand side of the standard keyboard, including the numeric keys 〇~9, Num Lock key, other operations, the keys and more The group refers to no lights (Num Lock, Caps Lock, Scroll Lock, etc.). Among them, except for 5, the other numeric keys are shared with the various direction keys or function keys, and the switching is performed by the Num Lock key. When pressed, the expansion keyboard and the keyboard on the notebook enter the Num Lock state at the same time, and Light up the Num Lock indicator at the same time. As can be seen from the above, the expansion of the keyboard is mainly used for the input number __ 3_ This paper scale translates the 3 standard (CNS) A4 specification (21G X 297 public wear) ~ -- (Please read the back of the Ba first) Matters fill out this page) Order --------- Line - 1307852 B7 Five, invention description () word use, but the expansion of the keyboard still allows the number keys and other functions (direction) keys to share, as for The use of the numeric or directional keys is determined by whether or not the Num Lock key is pressed, and this preparatory action is inconvenient for the user who uses the extended keyboard primarily for keying numbers. In order to improve the aforementioned inconvenience, some operators use a special driver to determine whether the key code sent by the computer is sent by the extended keyboard when a typing action is generated. If it is determined that the extended keyboard is sent, the key is automatically The code is converted to a digital code, so that the extended keyboard is always used to type a number. This method can solve the inconvenience of confirming its working mode and pressing the Num Lock key to switch when using the extended keyboard, but there are many problems in itself. Problem: 1. The installation program must be executed: Since the above method is to identify the key code by software, it must be installed before use. Currently, most peripheral devices support "plug and play". That is to say, most users do not like or even install the driver. Although the above method can solve the problem, the program must be installed in advance, which is inconvenient for the user. 2 · There may be a “phase collision” phenomenon: due to the identification conversion through a specific software, it is likely to be buggy due to different applications, so that it cannot be used in some specific applications. It can be seen from the above that although there is a technology for locking the extended keyboard for digital typing through the software identification conversion key code, there are still inconveniences or incompatibility problems, so it is necessary to further review and seek a feasible solution. ___4 This paper size applies to China National Standard (CNS) A4 specifications (210 X 297 public dreams) (please read the notes on the back and then fill out this page) Order -------- Line! f A7 1307852 V. INSTRUCTION DESCRIPTION (>) Therefore, the main object of the present invention is to provide an extended keyboard that automatically locks the working state without the need to install a program to facilitate the user to type in numbers. The main technical means for achieving the foregoing purpose is to make each key-in action of the extended keyboard include the following steps: sending a specific key code as a detection code to the host, so that the host sends back the working mode message of the keyboard; Mode message to determine whether the keyboard is currently in the Num Lock state; if the keyboard is in the Num Lock state, the key code of the pressing button is directly sent. If the keyboard is not in the Num Lock state, the key of the Num Lock key is sent first, and the keyboard is switched to In the Num Lock state, the key code of the pressed key is sent, and the restoration instruction code is sent to end the typing operation. Through the foregoing steps, regardless of whether the keyboard is in the Num Lock state, the key code sent by the extended keyboard represents the numeric key, so that the user can use the extended keyboard to input a large number of numbers without any pre-installation of any driver. The key code of the detection code can be the key of the Num Lock key, the Caps Lock key or the Scroll Lock key.

Figure 6: A plan view of a general extended keyboard. (2) Part number: (1 0) Expansion keyboard (1 1) switch The main technical means of the present invention is to expand the keyboard. Each key action is to first detect the working state of the keyboard (the original keyboard of the computer). The Num Lock state, according to the detected working status message, determines the key code to be subsequently sent, and each keystroke of the extended keyboard represents a specific number of typing. For the convenience of understanding, the following explains the principle of the keyboard working mode as follows: Take the general standard keyboard as an example, the right hand side has a 17-key button array and Num Lock, Caps Lock, Scroll Lock and other indicators, when used When the Num Lock button or the Caps Lock button or the Scroll Lock button at other positions is pressed, the corresponding indicator light will be illuminated. The working mode is as shown in the first figure A. When the keyboard sends Num Lock to the host computer, Caps Lock, Scroll Lock and other key keys of any key, the host computer will send Num Lock, Caps Lock, Scroll Lock and other indicators to the keyboard according to the working status at that time (as shown in Figure B). ), in order to illuminate the corresponding indicator light through the microprocessor built into the keyboard, therefore, the paper size is applicable to the Chinese National Standard (CNS) A4 specification (210 X 297 mm) (please read the precautions on the back) Fill in this page) — I,· — I book · --- Line — ----— —— — — —------ 1307852 A7 - ____B7_____ V. Description of invention (Γ) The indicator message sent back by the host computer can understand the keyboard. Whether it is in the Num Lock state before. When an expansion keyboard is connected to the computer, its "Num L〇ck" status is the same as the original connection keyboard, that is, the original connection keyboard is in the "Num Lock" state, and the expansion keyboard is in the "Num" state. "Lock" state 'The original connection keyboard is not in the "Num Lock" state, the expansion keyboard is also in the non-"Num Lock" state, and the present invention locks the expansion keyboard in the "Num Lock" state regardless of whether the original connection keyboard is in the "Num Lock" state. The Num Lock state can be understood from the above description. The following is a detailed description of the specific technical features of the present invention. The following describes the following steps of the extended keyboard: Refer to the second figure): Send the specific key code as the detection code to the host, and let the host send back the working mode message of the keyboard; identify the working mode message sent back by the host to determine whether the keyboard is currently in the Num Lock state; In the Num Lock state, directly send the key code of the pressing button, such as the keyboard is not in the Num Lock state, that is, first send Num Lock The key code, switch the keyboard to the Num Lock state, and then send the key code of the pressing key; send the recovery instruction code to end the typing action. Among them: In the foregoing process, in order to lock the expansion keyboard in a different working state from the original connected keyboard In each key-in action of the extended keyboard, 7 paper scales will be applied to the Chinese National Standard (CNS) A4 regulation ^· (210 X 297 mm) ~ (please read the notes on the back and fill in this page) Order ---------line! 1307852 A7 ----- B7 - - ----^ V. Description of invention (b) A step of determining whether the keyboard is currently in the "Num Lock" state, that is, sending a detection code, the host receives the detection code After that, a keyboard will be sent back: ^ to the original connection keyboard and the expansion keyboard. At this time, the expansion keyboard can be broken according to the current state of "Num Lock". If so, the expansion keyboard will directly send the button pressed by the user. Key code to the host, otherwise, if the keyboard is not in the "NumLock" state, first send the "NumLock" key _ code, switch the keyboard state to "Num Lock" state, and then send the key code of the pressed button to the host, and finally Restore the command code, restore to the original state, and $ into a typing action. The foregoing detection code may be a Num Lock key, a Caps Lock key or a Scroll Lock key. According to the interaction between the extended keyboard and the host computer, the front row Num Lock key, Caps Lock key or Scroll Lock key may be known. When the key code of any key is sent to the host computer, the host computer will send back the working information of three indicators such as Num Lock, Caps Lock and Scroll Lock to the original connection keyboard and the expansion keyboard. The expansion keyboard can be used to transmit Num Lock through the message. The clear state can be used to know whether the keyboard is currently in the Num Lock state, and thus the Num Lock key, the Caps Lock key or the Scroll Lock key can be used as the detection code in the above detection step. Among them, because the Scroll Lock key is usually not used, the key code of the Scroll Lock key is used as the detection code, which can effectively prevent the BUG from appearing. Furthermore, some keyboards have a function of: "Shift" key plus a button to generate the shared function of the button. For example, in the Num Lock state, the 'Shift' key plus the number key 8 means the cursor "up" (丨), the "Shift" key plus the number key 1 means the cursor moves to the end of the paragraph (End); Paper scale applies to China National Standard (CNS) A4 specification (210 X 297 public) " ^Please read the back <general matters and fill out this page> order /ί-----线丨· rl 1ΙΙΙΙΙΙ1 — — — — — — B7 1307852 V. INSTRUCTION DESCRIPTION (p) (Please read the note on the back and then fill out this page) As shown in the third figure, it is a workflow of another preferred embodiment of the present invention. The basic flow is substantially the same as that of the previous embodiment. The difference is that when the expansion keyboard is judged to be in a non-Num Lock state, the key code of the "Shift" key is sent first, and then the key code of the pressing key is sent, and the rest of the processes are the same. In addition, based on the diversification of product functions and the premise of meeting different customer needs, the expansion of the keyboard is always locked in the digital typing function, which may affect a few functions of using the extended keyboard to perform cursor movement, etc., so the present invention can be set on the expansion keyboard. The switch is provided for the user to select whether to perform the working state locking function. If the lock is not locked, it is the same as the conventional expansion keyboard, and the working state is the same as the computer keyboard; if locked in the numeric typing function, the foregoing workflow of the present invention is executed. Lock all typing actions to numeric typing. The specific structure is as shown in the fourth figure, mainly by setting a switch (1 1 ) on the mode switching pin of the microprocessor (10) in the expansion keyboard, and changing the switch by the switch (1 1 ) The mode switches the potential state of the pin to select whether to perform the lock function. It can be seen from the above that the present invention provides a control method for converting the extended keyboard and the computer keyboard into different working states, and converting all the typing actions into digital typing, so that the method does not need to be installed in advance to satisfy the general consumer. For the plug-and-play requirements of peripheral devices, the consumer is more convenient in expanding the operation of the keyboard, so it has significant practicality, novelty and progress, and meets the requirements of the invention patent, and filed an application according to law. ___9 This paper scale applies to China National Standard (CNS) A4 specification (210 X 297 public Chu)
