[Prior Art] In the conventional electronic device, in the case of a portable electronic device, especially a mobile phone or a personal digital assistant (PDA), the button is usually placed on the same side of the screen as the screen, and the disadvantage is that it is accidentally touched. The problem, as well as the wear and tear, and the overall appearance of the accumulated capital, the complexity of the lines is not simple and powerful. Oh, so to avoid the above problem, 'someone later set up a live on the phone's keyboard, 盍' will cover the button to avoid accidental touch. However, the disadvantage of this type of movable cover is that when the movable cover is opened, the overall size of the mobile phone is increased, which is usually lengthened, that is, an extra piece of activity is covered, and this extra piece is taken out. It is possible that the collision may be caused by an accident, which is very annoying.匕 Refer to Figure 1 and Figure 1 for the conventional mobile phone 1. This is very popular at present, it will set the button group 14 on a movable cover 12, when the activity is 19葚

Connecting the component and rotating to the second device, the power device transmits a power mechanism through the first device, and the motor device is attached to the motor, and the thin plate is connected to the motor. The power of the pivotal member and the second pivot; the component, the power of the first machine is transmitted to the second switch, and the second pivot component is placed in the same manner, wherein the host is further A limit switch is set, and the limit switch stops the motor when the catch is reached to the clamp. < 1259352, the electronic device, wherein the power mechanism comprises a first elastic device and a second elastic device, wherein the first elastic device is configured to rotate the thin plate from the flat surface to the second surface a face side, and the second elastic means for flattening the first sheet to the second side. The electronic device as described above, wherein the first surface further comprises a first fixing member, and the thin plate is fixed on the first surface. The electronic device as described above, wherein the second surface further comprises a second fixing member for fixing the keyboard to the second surface. An electronic device that can be described in the following description, wherein the turning device has a splicing member and a flat member; the cymbal electronic device 5 is provided with a thin plate fixed, and the detachable mechanism is used when the second face or the second face is fixed. Has a spring position. The sub-devices, wherein the second surface is provided with a - function key, and the hollow area is located, and the electronic device is as described above, wherein the thin plate is transparent. The device of the present invention also provides an electronic device having a hidden keyboard having a second side and a second side. The host system rotates the keyboard to the second side of the side to flip the second side. The straw is turned over by the younger brother, so that the keyboard is flattened to the outside of the interface, such as the field mu, the secret of the secret, the wealth of the first plum and the find, the fine money _ light material - pivotal yuan flat attached to the fixed The piece fixes the keyboard 7 1259352 as described above, wherein the second surface is provided with a work area μ & _ board is further opened - hollow area force, 'and the hollow area makes the function key exposed. When the field 1 is read privately, the electronic crack is as described above, wherein the thin plate is transparent. [Embodiment] The electronic two-two im'f f invention - the kind has a hidden keyboard u ±, Ang Wo to pick up the piece 21 and a younger two framed elementary plant 99 Xi fine 2 / map city has more - thin plate , set on it - keyboard discussion. Ϊ 而 L In the electronic I set the screen 2G of the host 2, the device field 2 can display the keyboard 23, completely _ hidden in the lunar surface 20b' as shown in Fig. 2A. In the keyboard 23γ, T is crazy, the noodles and the thin plate 23 are used by the coffee factory. Various handheld devices such as mobile phones (mobile phones, personal digital assistants d_ assistant), walkmans and flash drives are all ten. Help Figure 21 Figure 'is an action of the electronic device with a hidden keyboard. When you want to use the keyboard 2 face 2〇b with the first pivotal component 21 as the axis, make thin: two? The moon is rotated, the front side 20a, at which time the thin plate 23 is not completely flat = ij the second connecting element 22 can be flat on the front side 2Qa. The material of the light-transmissive material can be used to make the display of the screen 2 through the seesaw 23. Wei ΐ ΐ 产 产 产 产 ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ The second pivoting element 22^ is positioned to the front side. When the sheet 23 reaches the position, the -& 1259352 = hollowed out area 23a acts to keep the function keys that are originally in the front pool to remain exposed for easy access. When the entire screen 20 is to be used, the thin plate 23 can be rotated back to the back surface 20b in the reverse order. Referring to Figure 4, an exploded perspective view of the electronic device of the present invention. The first rotating component 25 is disposed on the sub-device main body 2 for accommodating the first pivoting component 2i to rotate inside, and the first pivoting component 21 is further provided with a connecting portion 21a; and the second, the second 22 A second rotation amount 23b is also provided, and a rotating arm 亥^hai connecting portion 21a is pivotally connected on both sides thereof, so that the rotating arm 22a and the connecting portion 21a can be opposite to each other and drive the rotation of the thin plate 23, and the thin plate 23 is self-backed 2 〇b (please match the 2A, j) to the front 20a. Further, a hollow area 23 is also provided on the thin plate 23 to facilitate the use of the function keys 24. Please refer to Fig. 5 for an illustration of another structural design of the electronic device (4) of the present invention. Wherein, the electronic device domain 2 is provided with a first-rotating portion & a pivotal connection for the younger brother--the pivotal member 21, and the first pivoting member 21 is further provided with a connecting portion 2u for pivoting with the second young member 22. Therefore, if the -_ component ^ can transfer the thin plate from the back surface 20b (please match the 2A, B picture) to the front side 2〇a, and then through the first - pivot connection. The thin plate 23 is rotated and attached to the electronic device main unit 2. A hollowed out area 23a is also provided to facilitate the use of the function keys 24. Refer to Section 6® for the (10) construction diagram of the present invention. The present invention provides a power mechanism for the purpose of facilitating the opening or concealing of the control 23, and the power mechanism includes the motor 3 and the transmission mechanism %, the power transmitted through the power 3, and the transmission effect of the transmission mechanism 30. Having the first pivoting member 21 and the splicing member 22 allow the thin plate 23 to automatically rotate between the front surface 2〇a and the back surface 2〇b without the user having to manually pull it by hand. The action button (not shown in the figure) or the voice control method can be used to invert the thin plate 23. Moreover, the transmission mechanism 3 can be a link mechanism, a gear set, a pulley set, and the rib drives the rotation of the first pivotal member 21 and the first pivotal member 22, and the transmission mechanism 3G can also be a programmable shifting device. By changing the design of the first pivoting member 21 and the second pivoting member 22, for example, first rotating the first pivoting member 2 and then rotating the second pivoting member 1259332 22 or rotating first The two pivotally connect the tree 22, and then turn the first pivotal joint to rotate, but take the speed of the ke.
