- the character "ZXCVB" can be entered separately.
- the same function is also applied to the right sliding plate 4-2 with five buttons.
- the left sliding plate 4-1 and the right sliding plate 4-2 are connected by the sliding groove 4-5 and the fourth returning spring 4-4 so that the left sliding plate 4-1 and the right sliding plate 4-2 Mutual displacement, and due to the elastic force of the spring 4-4 in the fourth round, the wrist can clearly feel "aligned”, "left front right rear",
- the wristband 4_6 is mounted on the left sliding plate 4-1 and the right sliding plate 4_2, so that the left and right gloves can hold the keyboard after the wristband 4_6, so that people can type in various postures such as left, standing, and squatting, and The left sliding plate 4-1 and the right sliding plate 4-2 can be easily pushed by the wrist.
- buttons 4-7 are mounted on the left sliding plate 4-1, which are named as LK1, LK2, LK3, LK4, LK5, and five input buttons 4-7 are also mounted on the right sliding plate 2, respectively named : RK1, RK2, RK3, RK4, RK5, these 10 input buttons 4- 7 are the main input keys for all English letters, symbols and numbers. Since the commonly used characters are not only 26 English letters, but also symbols, numbers, etc., there are 3 fourth switching buttons 4_9 on the keyboard, named Caps lock (Case Switch) and Numl ock (Digital Switch). , Symlock
- buttons can input uppercase characters, numbers and symbols respectively.
- important control keys "Enter” and “De l” are installed as the third auxiliary button 4-8 at other positions on the slide.
- a sliding varistor is installed at the joint of the left sliding plate 1 and the right sliding plate 2, and when the left and right sliding plates are in the "alignment", "left front right rear",
- 10 main buttons are mounted on the left and right sliding plates, and the 10 main buttons are named LK1, LK2, LK3, LK4, LK5, RK RK2, RK3, RK4, RK5. (5 left hand, 5 right hand).
- These 10 buttons are used for inputting three types of characters: letters, numbers, and symbols. Therefore, three fourth switch buttons 4-9 are also required to implement these three different types of character input.
- the three fourth toggle buttons 4-9 are: Cap Lock, Num Lock, Symbo l Lock.
- the corresponding character-key coding for these three types of character input is as follows:
- the arrangement of "QWERTY" keyboard keys has become a habit.
- the present invention does not intend to change the original keyboard key arrangement.
- the lowercase English alphabet key table formed by the button and the left and right sliding plate misalignment positions can be arranged as shown in Table 1:
- the main button When the N strain Lock is closed, the main button is used for the input of 10 Arabic numerals and some common symbols. Because the number of symbols exceeds 30, and there are only 10 Arabic numerals, some of the symbols are placed in the N-spin Lock ON state input.
- the number and partial symbol key positions are arranged as shown in Table 2:
- the swaying character keyboard has only 15 buttons, which can realize the characters that can be input by 101 buttons on the standard computer keyboard.
- Fig. 17 is a schematic diagram of the key circuit of the button on the left sliding plate 1 of the swaying character keyboard and the fourth switching button 4-9, which is the same as the button circuit of the button on the right sliding plate and the fourth switching button 4-9. From the circuit diagram, it can be seen that when any one of the buttons is pressed, since the relative positions of the left and right sliding plates are different, the sliding varistor generates different resistances, so that the keyboard circuit recognizes and distinguishes different letter symbols. Similarly, when the three fourth switching buttons 4-9 of Caps Lock, Num Lock and Symbo l Lock are opened or closed, the identification resistance is paralleled with the main button resistance, so different resistance values are also generated for the keyboard circuit. The recognition distinction produces different alphabetic symbols.
- the button of the present invention is three-dimensionally mounted according to the shape of the finger distribution.
- the finger When the main character is input, the finger is basically fixed on the button, which reduces the range of motion of the hand and improves the character input efficiency.
- the ⁇ -type character keyboard Due to its small size and portability, the ⁇ -type character keyboard is especially suitable for character input on tablets, mobile phones, wearable computers, etc. It can also be widely used on other smart devices (CNC equipment, game consoles, household appliances, etc.).
- the principle can also be applied to a virtual keyboard, so that the virtual keyboard occupies less area of the screen, which is convenient for application.
