Description

M254717 V. Creation Instructions (1) [Technical Field] This creation is about an improved structure of multi-directional keys, especially a kind of setting that is generated by touching two adjacent touch points on a circuit board corresponding to a certain guide point to generate electricity. Enabling signal, which can avoid the misoperation of the conductive film in other directions to generate an error message when performing a multi-directional selection operation. ^ Improve the button. ^ ^ [Previous technology] At present, the electronic devices related to the multi-directional key structure are widely used, such as personal digital assistants (p DA), mobile phones, electronic computers, and even general household appliances or automobile panels. The keyboard often includes multi-directional or multi-function keys. The multi-directional or multi-function keys generally include ^, two directions down, or four directions up, down, left, and right to control the information on the screen. Select the movement or cursor. mobile. The multi-directional or multi-function keys are mostly integrated designs, in which a fulcrum is provided in the center of the key. When pressed in one direction, the other directions will be slightly lifted due to the leverage of the raised fulcrum. The lower end of the direction forms an electrically conductive contact, which mainly consists of a button and a conductive elastic sheet for pressing. It is a known technology that can be easily considered by those skilled in the art, but the above-mentioned multi-directional or Multi-function keys are expected to face up or stay in the other directions when pressed in one direction to avoid false signals of mis-triggering in other directions. However, in general operation, the pressing direction will inevitably produce skew, so it will As a result, interference occurs and two conductive shrapnels in different directions are touched at the same time, which causes false information. H / Brothers are constantly emerging, so the industry continues to introduce new and improved designs for this, which can improve it. For example, the announcement No. 5 3 7 4 8 9 No. "9211102.ptd Page 5 M254717 V. Creation instructions (2) Improvement of the key structure of the evening direction <__>" Multi-directional key ... Country "丄 Announcement 5 No. 55142 Structure of a multidirectional button. 1 Patent case, revealing the above-mentioned typical improvements in the above-mentioned patents, or increasing the design value of IK = off the multidirectional key structure; for example, the above-mentioned public J number 5; = title 'to increase industry Improvement of the above structure (II) Basin 4 8 9 "Multi-directional key joint seat, the rubber: the inner side forms the stamp: the circuit board is provided-the rubber is fixed on the inner side of the rubber, and the rubber on the top surface of the accommodation chamber Block stone switch, and another on the rubber seat ::::: The printed circuit board is provided with magnetism that can be pressed down at the-part of the deflection: the button part of the direction button 'This stone switch sends a signal to the side The magnet is close to the corresponding magnetic structure. However, in the above structure, when the button part of the t-directional multi-directional key control directional button is pressed, there is a coincidence point. When the two magnet switches are pressed and pressed, because of 哕; The seat is skewed and makes the magnet act, so it is easy to send 3ΐ !: The seat cannot produce accurate positioning. In order to change the sound = 1 phenomenon, an error message is generated. In order to improve the above disadvantages, it is like the princess 2 "multi-directional button National New Type of Interest 14 It consists of a body, an elastic washer, and a contact layer, each of which is pressed; the bottom is provided with a cavity, a contact portion corresponding to the independent body is provided on the contact layer, and a circular layer is provided on the contact layer. A bump is provided at the top of the central two-known bonding portion to correspond to the bottom cavity of the button body, and the structure of the button, because the button bodies will not interfere with each other at all = such interference, but there is still a structural design Missing on: =

92111〇2.ptd Page 6 M254717 V. Creation instructions (3) There are a lot of numbers, and the contact pressure of the bonding part is too important. If you touch it by mistake, please refer to the situation. From the figure, the guide point 4 1 turns on the current. Instead, partial body 40 is too heavy 'or completely partial as expected. It is difficult to match, and the round central platform on the contact layer is integrated with a plurality of elements. In operation, it may still be necessary to conduct conductive springs due to the button body or the central time, and it may also cause contact with the other several joints. The possibility of generating false signals. Figure 1 is a traditional and obvious error signal. It can be clearly seen that when a hand is pressed on the key body 40, an accurate single-point contact can be made to make the conductive elastic sheet 4 2 to produce the correct one. Signal; if the hand is not pressed on the guide point 4 1 = on both sides of the V-point 4 1 or when the key is pressed, a double-point pressing on the conductive elastic sheet 4 2 may cause a false signal This phenomenon does not mean that our structure is more streamlined and related industries need to be overcome urgently. Therefore, how to make the multi-directional key to reduce the probability of misoperation in the application is an important issue. [New content] In view of the lack of the above-mentioned traditional people who need to be modified to cover the lack of it, the author of this research is the author of this book. Therefore, the main purpose of this creation is to mention the structure of Erliang, mainly to use special circuits. / 、 — The directional button is set to correspond to two or two guiding points on the button = upper: a conductive piece position, which needs to press and touch two of the circuit board at the same time: the position setting button complements the guidance between the two positions Point indicates the direction of the direction: bit = electric film can produce n. In multi-directional selection operation, erroneous υ: This method can effectively eliminate domains and touch conductive films in other directions, and j

M254717 V. Creative Instructions (4) The situation where an error signal is generated.

With the above structure, the configuration of each guide point of the key body corresponds to between two convex buttons, so that when the corresponding corresponding guide point is pushed down, the two convex buttons corresponding to its lower end can be lowered by being pressed at the same time. And contacting the conductive pieces in the two adjacent positions in the circuit board, and in conjunction with the electronic setting, the conductive pieces in the two positions must be turned on at the same time to generate an enable signal. In this way, the difficulty of misoperation can be relatively increased, and even the misoperation can be caused. Impossible, it is effective to eliminate missing persons who interfere with misoperation. [Embodiment] ^ As for the detailed structure, application principle, function and effect of this creation, please refer to the diagram and make a complete understanding. Please refer to Figure 2. From the figure, it can be clearly seen that the improved structure of the directional keys on the evening of this creation mainly includes at least: a key body 10, an elastic film 20 and a circuit board 3. 〇 consisted of; keypad
