Description of the Invention: [Technical Field] The present invention relates to a casing structure of an electronic device, and is a casing structure of an electronic device having a button. [Prior Art] Due to advances in technology, 'portable electronic products have developed many devices that can generate control signals in recent years to move the cursors (four) on the display), such as the rat, the remnant ball (track ball), joystick Q0y_sticks), trackpad (she spit pad), and trackpoint and so on. Taking a notebook computer as an example, almost all of the notebook computers have a touchpad and a button group that cooperates with the touchpad. When the user slides with the finger on the surface of the touchpad, the display can be controlled. The position of the cursor on the top, and with the button _ press 阙 operation, the user can easily complete the operation point selection function of the input device such as the beta mouse, so there is no need to connect the mouse to the notebook computer. • In terms of the button group of the touch panel, the button group structure is composed of a key cap and a cantilever member, which is a cantilever structure and has a set of holes at the end of the suspension member. The casing of the notebook computer is provided with a through-groove that matches the size of the button group, and a plurality of heat-melting columns are disposed at a position adjacent to the through-groove inside the casing. When the button group t is set in the casing, the key cap is correspondingly placed in the through slot opened in the casing, and the cantilever member is sleeved on the key cap, and the sleeve hole of the cantilever member is correspondingly set on the machine. Inside the shell _ gallop. Then, the squadron (4) is melted by heating, and the melted hot-melt column material is fused with the cantilever member, so that the key cap can be installed by the connection of the elastic force cantilever member of the cantilever member by the 201117247 Reciprocating elastic displacement with respect to the casing on the casing and the keys. The custom button group must be added separately, and the arm member can make the key cap elastically displace relative to the casing. Therefore, the component of the miscellaneous piece must be produced separately, and the shouting process is too complicated, resulting in excessive cost of the object and manufacturing cost. High problem. Moreover, the above-mentioned conventional hot-melt fixing method is easy to operate due to improper operation, causing skew in the opening π of the button, making the gap between the button group and the opening of the casing uneven, or by heat fusion. Improper damage to the button set. The production of these problems is finally squandered, and the axis makes the production cost of the notebook computer increase. When the user operates the notebook computer for a long time, if the button group needs to be more lion-like, it will be replaced by the shell. This will not only increase the cost of maintenance, but also make the maintenance procedure relatively labor-intensive and time-consuming. SUMMARY OF THE INVENTION In the above question, the present invention provides a casing structure of an electronic device, whereby a modified button _ a large number of components leads to a high manufacturing cost, and a button set is formed by using a heat-fusible fixing method. It is impossible to pay attention to the problem of being fixed on the casing and scrapping the casing. The invention discloses a housing structure for electronically oscillating, the electronic device has a circuit board, and the circuit board has at least one micro switch. The casing structure comprises a casing and a button, wherein the casing has a slot and at least one elastic arm, the elastic arm is connected to the casing, and the elastic arm is suspended in the slot. The button system is disposed in the slot and is in contact with the elastic arm, and the button is displaceable relative to the housing. The opposite sides of the button respectively have hooks, and the 201117247 is hooked to the housing, respectively, and the button is held in the normal position by the normal pushing of the elastic arm. When the button is forced to the trigger position, the button elastically deforms against the elastic arm, and the button triggers the micro switch. The invention is combined with each other by the card fishing of the button and the hook of the casing, so that the button is arbitrarily set on (4). Therefore, when the button needs to be replaced, it is only necessary to remove the button from the button by releasing the hook between the button and the housing _, which can not only avoid the replacement of the fixed age. The button of the appeal type causes the whole set of shells to be scrapped due to inadvertent operation, and at the same time speeds up the rework. Moreover, the elastic arm system that drives the reciprocating displacement of the button is integrally formed with the housing, and does not require an additional cantilever assembly, which greatly simplifies the number of assembly components and the assembly process. The above description of the present invention and the following description of the embodiments are intended to illustrate and explain the principles of the present invention, and to provide a further scope of the invention of the present invention. Further explanations. [Embodiment] The electronic device of the present invention The structure of the casing, the electronic device can be a notebook, a display, a camera, a mobile phone, a personal digital assistant (PDA) or a global positioning system (Global Positioning) System, GPS) and other devices with button operation. The above is for illustrative purposes only and is not limited thereto. Hereinafter, a notebook computer will be described as an embodiment of the present invention. 2011-17247 1A to 3D are perspective views and cross-sectional side views of an embodiment of the present invention. As shown in the figure, the casing structure of the present invention is provided on the electronic device 100 having a circuit board 110. The circuit board 11 is electrically disposed with two micro switches 111. The housing structure disclosed in the present invention comprises a housing 12 and a button H. The housing 120 has a slot 121 and at least one resilient arm 122. The slot 121 extends through the housing 120. A limiting wall 123 is further protruded from the lower periphery of the slot 121. The leading edge of the limiting wall 123 is formed with a guiding inclined surface 1231, and the guiding inclined surface 1231 is oriented opposite to the circuit board 110. Tilt setting. The elastic arm 122 and the housing 120 are integrally formed, and the elastic arm 122 is designed to be bent and twisted. One end of the elastic arm 122 is a connecting end 1221 , which is connected to the periphery of the slot 121 , so that the elastic arm 122 and the housing 12 〇 are connected to each other; the other end of the elastic arm 122 is a free end 1222 and is suspended. In the slot 121, the resilient arm 122 has a displacement stroke for the housing 12〇, and the free end 1222 of the resilient arm 122 can be selectively coupled to the housing 12 to increase the elasticity of the resilient arm 122. Deformability. However, the number and shape of the elastic arms 122 are mosquitoes according to the actual design, and the miscellaneous arms 122 of the present invention can also be installed and suspended in the external structure 121 β, which is not limited to the embodiment disclosed in the present disclosure. . Further, the upper side of the elastic arm 122 is further provided with a plurality of bumps 1223, and the positions of the respective bumps 1223 are located at the bends of the elastic arms 122, and are evenly distributed on the boiled boil 122. It should be noted that the position and number of the bumps 1223 in this embodiment may be light according to actual requirements (4), and are not limited thereto. 201117247 Please continue to refer to "1" to "3". The button 130 is roughly a long rectangular plate structure whose size matches the size of the slot 121 of the housing 120, so that the button 130 can be accommodated in In the slot 121, the intentional person is prevented from breaking the coupling relationship between the two members from the gap between the button 13 and the button 130. The two opposite sides of the button I% have a hook 131' extending toward the circuit board 11 ,, and the end edge of the hook 131 is further provided with a sliding slope 1311, and the sliding slope 1311 faces the limiting wall 123' And the sliding slope 1311 and the shape of the limiting wall 123 match each other. In addition, at least one contact protrusion 132' is protruded from a side surface of the button 130 facing the circuit board 110. The number and arrangement positions of the contact protrusions 132 correspond to the micro switch ill on the circuit board 110, respectively. When the button 130 is installed in the slot 121, the hook 131 of the button 130 is attached to the guiding slope 1231 of the limiting wall 123 by the sliding inclined surface 1311, and the hook 131 slides along the guiding inclined surface 1231 through the sliding inclined surface 1311. Displacement into the interior of the housing 12, at this time the hook 131 hooks the limiting wall 123' to prevent the button 130 from falling off easily from the housing 12#. The button D0 is in a normal contact relationship with the elastic arm I22, and the limit action of the card fishing 131 enables the button 130 to reliably reciprocate/displace the housing 12A. In detail, the bump 1223 of the elastic arm 122 is normally placed on the button 130, and the button 130 is maintained at the normal position of the force by the elastic characteristic of the elastic arm 122 and the normal state of the bump 1223 of the elastic arm 122. . In addition, the distance between the contact stud 132 of the tilt 130 and the micro switch exit is substantially equal to the protruding height of the convex point I223 (i.e., the protruding height of the bump rib is equal to the pressing stroke of the button (10)). 201117247 As shown in Figure 3 and Figure 4, when the button (10) is applied to press the button 130 down, the button 13 is pressed against the elastic arm (2) and deforms toward the plate m. The displacement bump 132 of the tree button 13 is in contact with the micro switch m, thereby triggering the micro switch (1) to perform the preset function 'and the button 130 abuts against the limiting wall 123 to avoid excessive pressing force As a result, the button 130 is disengaged from the slot 121. When the force applied to the button 130 is released, the elastic arm 122 returns to the unstressed state from the elastically deformed state, and is pushed to the normal position by the push button 13〇, and the contact stud 132 of the button 130 is not triggered at this time. Micro switch mountain. The casing structure of the electronic device disclosed in the present invention is such that the button and the casing shirt are buckled in a snap-fit manner, so that the casing is assembled or disassembled on the casing. If the reward button needs to be carried out in a more (4) situation, the button on the housing can be quickly and easily removed by simply releasing the fastening relationship between the button and the body, effectively avoiding the electronic method caused by the careless operation of the wire method (4). The shell of the device must be scrapped, and the speed of the shouting and heavy work is greatly increased. Moreover, the armature and the shell county which are driven by the age are driven, and the structure is fine. Therefore, the shell structure of the present invention does not require an additional arm assembly, thereby simplifying the number of assembly components and the assembly process.
