Field of the Invention The present invention relates to an electronic device casing and a method of assembling the same, and more particularly to a portable electronic device casing and a method of assembling the same. [Prior Art] With the continuous updating and development of technology, portable electronic devices such as mobile phones or personal digital assitants (PDAs) have been widely used in people's daily lives. Referring to FIG. 1, a portable electronic device 10 includes a first housing 11, a second housing 12, and a hinge 13. The hinge 13 hinges the first casing 11 and the second casing 12 together. Referring to FIG. 2 , the second casing 12 includes an upper casing 121 , a keypad 122 with a plurality of buttons 1221 , a circuit board 123 with a plurality of signal sensing portions 1231 , a lower casing 124 and a plurality of latches 125 . . The upper casing 121 and the lower casing 124 are coupled by the holding member 125, and the key plate 122 and the circuit board 123 are accommodated therein. Referring to FIG. 3 and FIG. 4, when the second casing 12 is assembled, the key panel 122 is first received inside the upper casing 121; then the circuit board 123 is received inside the upper casing 121 to enable signal sensing. The portion 1231 is corresponding to the button 1221. Finally, the lower case 124 is fitted to the upper case 121 and integrated by the holding member 125 to accommodate the button plate 122 and the circuit board 123 therein. However, the thickness of the second casing 12 of the portable electronic device 10 is also relatively thick, which does not satisfy the trend of miniaturization of the portable electronic device 10. 6 200904297 SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a portable electronic device casing having a small thickness. It is also necessary to provide a method of assembling the casing of the portable electronic device. A portable electronic device casing includes a key plate, a casing and a support plate. The key plate is fixed on the support plate, and the support plate is retained in the casing. The assembling method of the portable electronic device casing comprises the following steps: holding the key plate on the support plate; and accommodating the support plate with the key plate in the housing. Compared with the prior art, the portable electronic device casing adopts a support plate instead of the upper casing of the conventional portable electronic device, which greatly reduces the thickness of the casing, and is beneficial to the miniaturization of the mobile phone. . In addition, the assembly procedure of the portable electronic device casing is relatively simple. [Embodiment] The present invention discloses a portable electronic device casing and an assembly method thereof, which are applicable to a portable electronic device such as a mobile phone or a personal digital assitant (PDA), and the preferred embodiment of the present invention takes action. The telephone 20 is explained as an example. Referring to FIG. 5, the mobile phone 20 includes a first casing 21, a second casing 22 and a hinge 23. The hinge 23 bulges the first casing 21 and the second casing 22 together. The second casing 22 includes a key plate 221, a support plate 222, a circuit board 223, a casing 224 and a plurality of retaining members 225. The housing 224 is housed in the 7200904297 keypad 221, the support plate 222, and the circuit board 223, and is held by the retaining member 225. The keypad 2 21 is substantially a flat body 5 on which a plurality of buttons 2211 for inputting digits, characters, and the like are disposed. In this embodiment, the holding member 225 is a bolt. The support plate 222 is substantially a flat plate, and its shape and size are substantially equivalent to the button plate 221. The support plate 222 has a top portion 2221 and a bottom portion 2222 disposed opposite the top portion 2221. The support plate 222 is provided with a plurality of button holes 2223 extending through the top portion 2221 and the bottom portion 2222. The button hole 2223 is provided corresponding to the button 2211. A plurality of holding posts 2224 are protruded from the edge of the bottom portion 2222 of the support plate 222. The retaining post 2224 is adapted to cooperate with the retaining member 225 to secure the support plate 222 to the housing 224. In this embodiment, the holding post 2224 is a stud with a threaded hole (not shown). The circuit board 223 is substantially a flat body having a shape substantially equivalent to that of the key sheet 221 but smaller in size than the key sheet 221 . The circuit board 223 has a top surface 2231 and a bottom surface 2232 disposed opposite the top surface 2231. The top surface 2231 is provided with a plurality of signal sensing portions 2233. The signal sensing unit 2233 is provided corresponding to the button 2211 of the keypad 221 . When the button 2211 is pressed, the button 2211 then presses the corresponding signal sensing portion 2233, and the circuit of the circuit board 223 is temporarily turned on, thereby generating an electrical signal. The housing 224 includes a left wall 2241, a right wall 2242 opposite the left wall 2241, a front wall 2243 adjacent the left wall 2241, and a rear wall 2244. A recess 2245 for receiving the hinge 23 is defined in the front wall 2243. The left wall 2241, the right wall 2242, the front wall 2243, and the rear wall 2244 are connected into a square casing, and form a 8200904297 battery accommodation chamber 2247 and a component accommodation chamber 2248 connected to the battery accommodation chamber 2247. The component housing chamber 2248 is approximately the same size as the support plate 222. A plurality of latching holes 2249 are defined in the corresponding holding posts 2224 of the housing 224. Referring to FIG. 6 , FIG. 7 and FIG. 8 , when the second casing 22 of the mobile phone 20 is assembled, the circuit board 223 is first placed in the casing with the signal sensing portion 2233 away from the battery receiving chamber 2247 of the casing 224 . The component 224 of the body 224 is accommodated in the chamber 2248; then the key plate 221 is fixed on the support plate 222, and the button 2211 is aligned with the button hole 2223. In this embodiment, the button plate 221 is adhered to the support plate 222; Finally, the support plate 222 with the key plate 221 is received in the component accommodating chamber 2248, and the holding post 2224 is received in the holding hole 2249. At this time, the holding member 225 is clamped to the holding post 2224. Then, the key sheet 221, the support board 222, the circuit board 223, and the housing 224 are held, that is, the second housing 22 of the mobile phone 20. It can be understood that the holding member 225 can be omitted, and the supporting plate 222 and the housing 224 are held by the interference fit of the holding post 2224 and the holding hole 2249. It can be understood that the support plate 222 and the housing 224 can also be integrated into one, such as ultrasonic fusion technology. It can be understood that the key plate 221 and the support plate 222 can also be fixed by other means such as a threaded connection, etc. The second casing 22 is replaced by a conventional portable electronic device. The casing, the thickness of the second machine is 22, which is conducive to the miniaturization of the mobile phone 2, and the development cost and manufacturing cost of the machine is reduced. The action is reduced: The production is too. s j potential telephone 20 The assembly procedure of the portable electronic device casing is also relatively simple. 9 200904297 Single 0 In summary, the present invention complies with the invention patent requirements, and patent application is filed according to law.
