Corresponding to the f small when the Langer presses the keycap, the keycap pushes down the cantilever to produce elastic deformation, and the cantilever triggers the micro-motion on the circuit board to control the notebook to perform the preset function. However, the keycap of the above-mentioned button group is located at the middle of the cantilever of the casing, and the effective contact area is relatively narrow, so that the keycap must be pressed and pushed at the center of the fuel. If the user presses the _ key _ non-intermediate position (for example, press the [J key towel U), the action of the keycap is like the direction of the non-stressed direction of the board. This will cause the triggering to be poor, even It is a situation in which the triggering failure occurs, and it is not ideal in the touch feeling. SUMMARY OF THE INVENTION In view of the above problems, the present invention provides a casing structure of an electronic device, so as to improve the number of components of the conventional button group, the lead is too high, and the conventional button group is easy to generate trigger failure when pressed. problem.

The casing structure includes a casing, a 201112286 button body, and a pressing member. The control key body has a supporting portion, at least one pressing portion, and at least two elastic arms. The supporting portion is disposed on the housing, and the two opposite ends of the supporting portion respectively have a limiting hole. The button portion corresponds to the micro switch, and the two ends of the elastic arm are respectively connected to the support portion and the button portion so that the button portion has a displacement stroke with respect to the support portion. The pressing member is mounted on the button body, and the opposite ends of the pressing member respectively have a limiting member that abuts against the two limiting holes of the supporting portion. The pusher is selectively pressed against the button portion displacement and triggers the microswitch. The present invention simplifies the number of casing components and the assembly process by applying a force to the pressing member to cause the button portion of the button body to be deformed and displaced in conjunction with the triggering of the microswitch. Moreover, the pressing member is normally held above the button body through the mutual restriction of the limiting member and the supporting portion, so that when the user presses the non-intermediate position of the pressing member, the pressing force can be effectively directed toward the micro switch of the circuit board. The direction is transmitted, so that the pressing member smoothly triggers the micro switch to prevent the end of the pressing member from facing the non-stressed direction, thereby causing the trigger to fail, and also providing the user with a good touch feeling.
