At the top of the handle 13 there are two corresponding carts 132 on the sphere 131 protruding to grip the hollow of the hand-held position 14 of the present invention. In addition, on the side of the hand-held position 14 there are five plates on which the user can click a different button to make the key a specific function. The five plates are divided into a thumb operation area 142, a detection operation area 143, a stop, an unknown and weak finger operation area 144, a finger grip operation area 145 and a palm operation area 146. On the thumb operating area 142 there are two opposing semicircular selection keys 1421 and 1422 and a circular function key 1423 and a circular function key 1422 above and below the two opposing semicircular selection keys 1421 and 1422, There is a circular shift key 1424. On the side of the shift key 1424, there is one opposed semi-circular Ctrl key 1425 and one opposed semicircular Alt key 1426, which can be easily pressed both individually by the thumb. In addition, a wide-area Enter key 1428 for easy operation below the thumb operating area 142 is mounted.

On the detection operation area 143, there are two character keys 1341 and 1432. Like the detection operation area 143, the stop, unknown and ring finger operation area 144 has its own Character key 1441 (1442) 1443 for activating each of stop, unknown and ring finger. On the finger grip operation area 145, there is an Esc key 1451, and on the palm operation area 145, there is a space key 1461.

On the upper and lower sides of the stage 21 of the right stick type handle 2, there are clamping devices 22 and handles 23, respectively. On the top of the handle 23 there are two corresponding carts 232 on the protruding sphere 231 to grip the hollow 241 of the hand-held position 24 of the present invention. In addition, on the side of the hand-held position 24 there are five plates through which a user can click a different button to make the key specific. The five plates are divided into a thumb operation area 242, a detection operation area 243, a stop, an unknown and a weak finger operation area 244, a finger grip operation area 245 and a palm operation area 246. On the thumb operating area 242, there are two opposing semicircular selection keys 2421 and 2422. [ There are a circular function key 2423 and a circular shift key 2424 above and below the two opposed semicircle selection keys 2421 and 2422, respectively. On the side of the shift key 2424, there is one opposed semi-circular Ctrl key 2425 and one opposed semicircular Alt key 2426 so that they can be easily both pressed by the thumbs. In addition, a protruding area 2427 under the thumb operation area 142 is equipped with a wide-area Enter key 1428 for easy operation.

On the detection operation region 243, there are two character keys 2341 and 2432. Like the detection operation area 243, the stop, asymptotic and ring finger operation area 44 has its own Character key 2441 (2442) 2443 for activating each of the stop, the unknown and the ring finger. On the finger grip operating area 245, there is an Esc key 2451, and on the palm operating area 245, there is a space key 2461.

Basically, the hand-held computer keyboard is divided into two parts: right and left stick type handles (as shown in FIG. 6). Since these keys correspond to the respective fingers, the hand-held computer keyboard of the present invention is used as a predetermined typing habit of a conventional keyboard. 7 shows the arrangement of function keys (Insert, Page Up, Page Down, ↑, ←, ↓, →) on the hand-held computer keyboard. When the computer is turned on, the two corresponding carts 132 (232) on the sphere (s) 131 (231) protruding to grip the hollow 141 (241) of the hand- (As shown in FIG. 11). Therefore, the left and right stick type handles 1 and 2 and the hand-held positions 14 and 24 are fixed. When the user wishes to operate the left and right stick type handles 1 and 2 with the mouse, the user presses the Character keys 1441, 1442, 1443 (shown in FIG. 2441) 2442 (2443). In addition, the operation stops the two carts 132 (232) protruding to grip the hollow 141 (241) of the hand-held position 14 (24) (24) can freely move to the front, rear, right and left sides.

A detailed description of the operation of the hand-held computer keyboard is summarized as follows:

1. There are two actions to convert lower case to upper case. First, the user can press the Shift key 1424 (2424) and the Character key at the same time to make the key upper case, or the key can be lower case without pressing the Shift key 1424 (2424). Second, the user can perform the same function by pressing the Shift key 1424 2424 twice in succession, which is similar to pressing the Caps Lock key on a conventional keyboard. Thereafter, if the user desires to recover to lowercase, the Shift key 1424 (2424) is pressed again (as shown in FIG. 8).

2. The letters to be activated with each finger are as follows (as shown in Figure 6):

Left hand Right hand Index finger F4, F5, 4, 5, R, T, F, G, V, B F6, F7, 6, 7, Y, U, H, J, N, M stop F3, 3, E, D, C F8, 8, I, K ^, Asymptomatic F2, 2, W, S, X F9, 9, O, L, Ringer F1, 1, Q, A, Z F10, 0, P,;, `, /

3. When the right stick type handle 2 is fixed, the function key 2423 and the Back Space key 2451 are depressed, and then the function of the right stick type handle 2 is that the numeric key set / do. Meanwhile, the function when the Shift key 2424 is pressed is the same as the function when the Number Lock key of the conventional keyboard is pressed. This means that when the user presses Shift key 2424, the numeric key set / function key set will act as a function key set, but if the Shift key has not been pressed, the numeric key set / function key set acts as a numeric key set . If the user presses the Shift key 2424 again, then the numeric key set / function key set will act as a numeric key set. In addition, the function will be the same as the state in which the user fixed the left stick-type handle 1 and then pressed the function key 1423 and the Esc key 1451 (as shown in FIG. 9).

4. The spheres 131 and 231 correspond to the hollows 131 and 241 on the upper portions of the handles 13 and 23 in the left and right stick type handles 1 and 2, - Move the hand positions (14) and (24) freely to the front, rear, right and left. Based on these attributes, the user can operate the left and right stick type handles (1) and (2) like a mouse. 10 shows an example in which the user presses the Character key 1441 (1442) on the pause, asymmetric and ring finger operating areas 144 (244) if the user wishes to operate the left and right stick type handles (1) (1443), (2441), (2442), and (2443). In addition, the operation stops the two carts 132 (232) protruding to grip the hollow 141 (241) of the hand-held position 14 (24) ) 24 to move freely in the front, rear, right and left directions; This operation is executed as if it is a mouse (as shown in Fig. 12). Meanwhile, the functions of the character keys 1431, 1432, 2431, and 2432 on the detection operation areas 143 and 243 are performed as the left and right keys of the mouse, respectively. When the user presses any two keys of the Character keys 1441, 1442, 1443, 2441, 2442, 2443 on the Stop, Unknown and Fingerprint operating areas 144, , The mouse-shaped function of the right stick type handles 1 and 2 will be deleted.

5. When the user presses the function keys 1423 and 2423, the character keys 1441, 1442, 1443, 2441, 2442 and 2443 are respectively operated with the numeric / character keys F5, F4, F3 and F2 , F1, F6, F7, F8, F9, F10.

6. If the user does not press the function keys 1423 and 2423 and the selection keys 1421 and 2421, the character keys 1431, 1432, 1441, 1442, 1443 and 2431 (2432) ) 2441, 2442 and 2443 will represent 5, 4, 3, 2, 1, 6, 7, 8, 9 and 0, respectively. When the user presses only the upper selection keys 1421 and 2421, the character keys 1431, 1432, 1441, 1442, 1443, 2431, 2432, 2441, 2442, , R, W, Q, Y, U, I, O and P.
