No need to design complex operation buttons for the input characters, so that the handheld device The key input device configured above achieves a space-minimized design. 200910157 The details of the embodiment of the present invention are described below. [Embodiment] The present invention provides a key input device for inputting characters by using a direction key, and FIG. 1 is a system block diagram of a key input device of the present invention, including a key input device 100, a controller 110, and a display screen 120. The key input device 1A includes at least a mode key 101 and a direction key 1〇2, and the design of the handheld device can be further controlled by the mode button 103 and the direction key 1〇2. To achieve the purpose of using the arrow keys to input characters, the menu button 1Q3 is used to select the input operation of the characters. Wherein the mode key 1Q1 is used to select a plurality of key array modes, and the key array of the selected mode is displayed on the display screen 120. In this embodiment, the plurality of key array modes refer to numbers Mode, symbol mode, Chinese mode, uppercase English mode and lowercase English mode; and direction key 102 is used to move between characters in four direction columns in the key array on display screen 12; through selective definition mode key 1 〇1 or the arrow keys 1〇2, used to select the input sub-character. Wherein the mode key 1〇1 is used to select the input character system by moving the cursor of the direction key 102 to the character, and then pressing the mode key 101 to complete the selection; wherein the direction key 1〇2 is defined for selecting the input character 'system The selection is made by moving the cursor of the direction key 1G2 to the character in which it is located, and then continuously pressing the direction key 102. ..., by pressing the >1 mode button 101 to sequentially set the digital mode, the symbol mode, the Chinese mode S, and the uppercase English mode to read the lowercase English mode. And on the display screen 120, the key array corresponding to the mode set by the key is displayed, and the original position of the cursor of the direction key 1〇2 is the center of each key array (input box 12〇1, please refer directly to the 200910157 test 3A) Figure does not). In addition to the numeric mode, after the input character is selected, the cursor of the direction key 102 returns to the original position. 2 is a flow chart of a method for inputting a character according to the present invention. The flow chart includes the following steps: selecting a plurality of key array modes by successively pressing a mode key, and displaying the key array of the mode in one Displaying on the screen (step 200); using the - direction key, for moving between the characters of the four direction columns of the key array on the display screen (step 201); and then selectively defining the mode key or the direction key for The input characters are selected (step 2〇2). Figure 3A is a schematic view of a first embodiment of the present invention. In addition to the mode key 101, the direction key 102 and the display screen 120 described above, an input box 1201 is further included for providing input and displaying a block for selecting a character. Fig. 3B is a schematic view showing the switching of the input mode by successively pressing the face keys in the first embodiment of the present invention. Herein, the order of the number of times is described in detail, which is only an embodiment of the present invention, and is not intended to limit the implementation of the present invention. The mode corresponding to any number of presses can be arbitrarily changed. For example, press the mode key 1〇1 once to switch to the lowercase English mode; press the mode key 1Q1 twice to switch to the uppercase English mode; press the mode key 101 three times to switch to the digital mode; press the mode key 101 four times to switch to the symbol Mode; press mode button 1〇1 five times, switch to Chinese Pinyin mode; press mode button 1 six times, _ to Chinese phonetic mode.曰 , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , you can switch to symbol mode by pressing the down button. Because of the consideration, the input will be in English, the number of 200910157 sub-symbols or the Chinese-specific input information. If the above-mentioned successive presses of the mode key 101 are arranged to switch between different modes, the input may be complicated. 'Therefore', for the design definition of successive face-to-face keys 101, it is more possible to switch between the two modes, that is, if the mode key 1(1) is not continuously pressed, as long as the mode key 1〇1 is pressed, it is Returning to the previous input mode, after the character is to be input, the mode key 101 is pressed again, that is, returning to the upper-input mode towel, and the P-type of the input mode can be switched between the two recent input modes. The operation can be performed again by continuously pressing the mode key 101, and the defined switching mode can eliminate complicated input operations. Fig. 4A is a key array of the lowercase English mode of the first embodiment of the present invention. In addition to the aforementioned mode key 1〇1, direction key 1〇2, the screen 120 1 further includes a round-in frame 12〇1 for providing input and displaying a selected input character_block. Since the invention is characterized in that the operation of the single-directional key is used to input characters, the shouting alphabet is taken as an example, in order to facilitate the input of the __solution 'this _ system will be the English prison __ according to the direction key four The sub-headers of the single direction "upward", down Q_), left (keft), and right (Eight) are arranged in the four direction columns of 26 English letters for user operation selection. The upper column is defined as π wxyz, the lower column is the mind 4, the left column is hijk!mn, and the right column is opqr st, so that the 26 (four) text letters are evenly distributed in the _ direction key array. Fig. 4B is a diagram showing the input method of the lowercase English mode of the first embodiment of the present invention. As shown in FIG. 4A, as described above, on the display screen 12〇200910157, the key array corresponding to the set mode is displayed, and the cursor original position of the direction key 102 is the center of each key array (input box 12〇).彳). In addition to the numeric mode, after the input character is selected, the cursor of the direction key 1〇2 returns to the original position (input box 1201). It is specifically described herein that the design of the present invention moves the cursor to the initial position of either side of the key array and falls in the four directions "up to but p", to T®own), to the left, to the right (gjght). On the prefix of the word, that is, the upper part falls below the 殳; the left side falls on the L; the right side falls on. However, this design mode is only for explaining the embodiment of the present invention, and is not intended to limit the implementation of the present invention, the cursor The initial position of any one of the keys to the key array can be arbitrarily changed. Therefore, according to the embodiment of the present invention, if the user wants to input "inventec" in the input box 12〇1, the actual input mode is: input "丨" When the "丨" letter is on the left side of the key array, you should first press the left button to move the cursor to the left of the key array. At this time, the cursor stays on the "I". You must press the up arrow three times to pause the cursor. On "i", at this time, as described above, the input key can be selected by selectively defining the mode key 101 or the direction key 彳〇2. If the definition mode key 101 is used to select the input character, the cursor of the direction key 1〇2 is moved to the character, and then the mode key 101 is pressed to complete the selection; wherein the direction key 102 is defined to select the input character. Move the cursor of the direction key 1〇2 to the character it is, and press the arrow key 1〇2 to continue the selection. In this embodiment, by defining the mode key 1 for selecting the input character system, by moving the cursor of the direction key 102 to the character, the mode key 1〇1 is pressed to complete the selection, and then the button is pressed. The house mode key 1〇1 can complete the input of i”. After the input character is selected, the direction key 1〇2❾ cursor returns to the original position (input box 12〇1). In this way, the next character can be input, 200910157, the next factory nj, factory Vj, factory e", "nj, factory f", "e", "c into the same as the above operation instructions, please refer to 4 帛 帛 5A _ is the first part of the invention 'will not be repeated here. Array. In addition to the above-mentioned one-key mode of the word mode, the more scooping key 〇 1, the direction key 102 and the display screen 120 ^ are included in the 3-wheeled box, providing input and displaying .:=. Different from the key arrays of other modes, since the numbers are only (four) two and ten sub-fours, there is no f configuration to four directions, and the present invention only has ^ in the upper column for the user to select the input. Law. The cursor original position of the input mode of the digital mode of the first embodiment of the present invention is the center of each key array: = modulo r is listed above. , ten characters for = read in 'so' after selecting the input character, the cursor of the arrow key 102 needs to return to the original position (round the frame gamma), and can continue to stay on the selected input character. It is to be noted that the embodiment of the present invention is not used to limit the implementation of the present invention.

After the input character is selected, the cursor of the arrow key 102 continues to stay at the "1" position. In this way, you can enter the - character input, the same reason, the next "5", "8", "0", "2·, "1, "6 factory"" 〇 」 "4", "2", The input of "4" and "6" is also as described in the above operation description "凊参=第5B图*, and will not be repeated here. It is worth mentioning that the up key is defined here as follows: The reply is in the initial position "〇" to simplify the complicated operation. Fig. 6A is a diagram showing a method in which the digital mode of the first embodiment of the present invention is switched to the symbol mode. Since the key array in the digital mode is only listed in the number of 0 to 9 in the f direction, the Wei of the down key cannot be reflected in the actual number H of the input towel, so it can be switched by pressing the down key. The means of the simplification of the mode switching must be exemplified. The manner in which the singular key is used in this mode is merely illustrative of the embodiments of the present invention and is not intended to limit the implementation of the present invention. The functions corresponding to any of the keys in the mode can be arbitrarily changed. The first figure is the pinyin input of the Chinese mode of the first embodiment of the present invention, and the [solid key array] is the present invention. The key array of the θ input of the Chinese model gas in the first embodiment. Since the input method of the Chinese input method is mostly described here, only the pinyin wheel input and the phonetic input are explained, which is different from the digital, labor payment mode, and uppercase English mode. With the lowercase English mode, the input of Chinese mode 12 200910157 must have a waiting box 1202 for the user to select. Therefore, in addition to the actual operation, such as the above-mentioned digital mode and lowercase English mode, the pinyin wheel input and the phonetic input are completed. After the operation, the relevant characters appear in the candidate box 12〇2, and the user is required to input the character, and the county will not be described here. The above description refers to the key for inputting characters by using the direction key. In the first embodiment of the input device, the input operation is completed through a mode key and a direction key 102' or by using only one direction key 1〇2, please refer to FIG. 8A as the invention. A schematic diagram of the H. The mode key 101 can be configured without being integrated with the four direction keys, that is, it can be additionally independent of the - button, and further includes a menu button 103 for selecting the input operation of the character. The corresponding function menu of the menu button 103 can be defined according to the functional requirements of the handheld device. Referring to FIG. 8B, it is a schematic diagram of the third embodiment of the present invention. The actual key input device 100 of the present invention is necessary. The feature only needs one mode key 101 and one direction key 1〇2, and the difference from the first embodiment is that the mode key 101 is combined with the direction key or separately. However, the specific key input device The configuration of 100 is not limited to the specific design. The embodiment of the present invention only describes the configuration of the various key input devices 100, and the specific necessary features are unchanged. Therefore, the combination of the mode key 101 and the direction key 102 The collocations are not limited to the scope of application of the present invention, and the derivable configuration combinations are not described herein. Although the implementation of the present invention is disclosed above, it is not intended to limit the present invention, and any skilled artisan is not Without departing from the spirit and scope of the invention, the invention may be modified and modified, and the scope of the invention is defined by the scope of the appended claims. 13 200910157 [Simple description] 1 is a system block diagram of the key wheeling device of the present invention.
