By doing so, it is configured to be stretched between the optical housing portion 10 of the lower case 3 and the leg portion 38.

Next, the operation of such a mobile terminal will be described.
First, a case where the side trigger keys 11 are attached to both sides of the lower case 3 will be described. In this case, the elastic member 23 attached to the button portion 22 inserted into the button insertion hole 26 of the lower case 3 in the first step is arranged in the lower case 3 together with the button portion 22.

  That is, in the first step, the plurality of pressing portions 22b of the button portion 22 are made to bite into the bulging portion 23a of the elastic member 23, and the elastic member 23 is attached to the peripheral portion of the button portion 22 by adhesion. In this state, the button portion 22 is inserted into the button insertion hole 26 of the lower case 3 from the inside of the lower case 3, and the peripheral portion of the elastic member 23 is arranged on the inner surface of the lower case 3.

  Then, in the second step, the contact member 24 is guided by the pair of guide portions 25 provided on the inner surface of the lower case 3 located on both sides of the elastic member 23 so as to gradually approach the elastic member 23 and overlap each other. . That is, in the second step, the guide rails 31 of the pair of guide portions 25 guide the pair of slide portions 32 of the contact member 24 in the vertical direction, so that the contact main body portion 27 tilted with respect to the guide rail 31. The electrode surface is opposed to this and overlapped with the facing surface of the elastic member 23 inclined with respect to the guide rail 31.

  At this time, the facing surface of the elastic member 23 facing the electrode surface of the contact body 27 is inclined with respect to the guide rail 31 at a draft of about 4 °, and similarly, the electrode surface of the contact body 27 is also tilted. It is inclined. Therefore, when the guide rail 31 guides the slide portion 32 of the contact member 24 at the start of guiding, the electrode surface of the contact main body portion 27 is changed as shown in the principle diagrams of FIGS. 10A and 10D. It is arranged with a clearance a between the facing surface of the elastic member 23 and the electrode surface of the contact body 27 in a state of being displaced in the surface direction facing the facing surface of the elastic member 23.

  In this state, when the guide rail 31 guides and slides the slide portion 32, the contact main body portion 27 is elastic member during the slide, as shown in the principle diagrams of FIGS. 10B and 10D. 23, the clearance a between the facing surface of the elastic member 23 and the electrode surface of the contact main body portion 27 gradually narrows.

  Then, when the guide rail 31 slides by guiding the slide portion 32 and the contact member 24 reaches the bottom portion of the lower case 3, at the end of the slide, the principle diagrams of FIGS. 10C and 10D are shown. As described above, the facing surface of the elastic member 23 and the electrode surface of the contact main body portion 27 face each other and are pressed against each other in a state of being overlapped with each other to be pressed against each other.

  Accordingly, when the contact member 24 is superposed on the elastic member 23, the contact member 24 and the elastic member 23 can be prevented from rubbing against each other and being damaged. Therefore, the contact electrode 27a of the contact member 24 and the movable contact 23b of the elastic member 23 do not rub against each other, and the contact electrode 27a of the contact member 24 is damaged or the movable contact 23b of the elastic member 23 is damaged. Since it does not occur, contact failure will not occur.

  In this state, when the contact main body 27 of the contact member 24 is pressed against the elastic member 23 and pressure-contacted, the pair of contact electrodes 27a of the contact main body 27 correspond to the plurality of movable contacts 23b of the elastic member 23.

  Then, the engaging protrusion 40b of the hook portion 40a provided on the support piece 40 is pushed by the inner surface of the screw hole 35, and the hook portion 40a bends. When the support piece 40 is inserted into the screw hole 35 of the lower case 3, the hook portion 40a elastically returns to position the engaging protrusion 40b on the end surface side of the lower case 3 which intersects the back surface of the lower case 3. It engages with the strap hole 37. As a result, the leg portion 38 is detachably attached to the screw hole 35.

  In this state, the attachment metal fitting 44 attached to one end of the hand belt 43 is attached to the metal fitting attachment portion 46 of the lower case 3, and the other end of the hand belt 43 is attached to the leg portion 38 attached to the lower case 3 and the lower case. 3 and is folded back at the leg portion 38, and the other end portion of the folded back hand belt 43 is superposed on the one end portion side of the hand belt 43.

Since the outer peripheral surface of the anti-slip portion 42 is arranged between the anti-slip portions 42 of the leg portion 38 and protrudes from the surface of the hand belt 43, the pair of anti-slip portions 42 of the leg portion 38 are placed on the mounting surface T. The boundary portion 10c on the one end side of the second surface 10b of the optical accommodating portion 10 contacts the mounting surface T and is mounted.

  Therefore, the device case 1 is placed on the mounting surface T without being hindered by the hand belt 43. In this case, even when only the hand belt 43 is detached from the device case 1 as shown in FIG. 17 with the legs 38 attached to the device case 1, the same arrangement as described above is performed.

  As a result, the device case 1 is favorably arranged on the mounting surface T in a stable state. That is, even if the grip portion 15 of the device case 1 is formed into a curved shape that can be easily gripped by the user's hand, the leg portions 38 attached to the grip portion 15 prevent the device case 1 from rolling on the mounting surface T. In addition, the device case 1 can be favorably arranged on the mounting surface T in a stable state.

Can be emitted.

  On the other hand, when the hand belt 43 and the legs 38 are removed from the device case 1 and the device case 1 is placed on the mounting surface T, as shown in FIG. 18, the second surface 10b which is a flat area. Does not contact the mounting surface T, and the end of the second surface 10b of the optical housing 10 opposite to the boundary 10c and the end of the lower case 3 on the inclined side 15a side. Is placed on the placement surface T.

  At this time, the end portion of the second surface 10b located on the first surface 10a side, that is, the boundary portion 10c is separated from the mounting surface T by using the reference portion as a boundary in the second surface 10b which is a flat area of the optical storage unit 10. The device case 1 is arranged on the mounting surface T in a separated state. Thereby, a gap is provided between the reference portion of the second surface 10b of the device case 1 and the mounting surface T.

  Therefore, even in this state, the sound collecting hole 10f for the microphone provided in the reference portion of the second surface 10b, which is the flat area of the optical storage unit 10, is not blocked by the mounting surface T, so that the microphone is used. The sound can be captured well. Further, even when a sound emitting hole for a speaker is provided in place of the sound collecting hole 10f for the microphone, the sound emitting hole is not blocked by the mounting surface T, so that the sound of the speaker is improved. Can be emitted.

When the other end of the device case 1 is mounted on the mounting surface T, the contact point of the second surface 10b with respect to the mounting surface T is defined with the reference portion on the second surface of the optical storage unit 10 as a boundary. different.

  In other words, in the device case 1, the inclination of the second surface 10b with respect to the mounting surface T when the leg portion 38 is attached and when the leg portion 38 is removed from the device case 1 is at the boundary of the reference portion. A gap can be surely and satisfactorily provided between the second surface 10b of the device case 1 and the mounting surface T only by turning in the opposite direction. Therefore, the sound can be satisfactorily captured by the microphone and the sound of the speaker can be satisfactorily emitted even when the leg portion 38 is attached or detached.

  As described above, according to the side trigger key 11 in this portable terminal, the side surface that is attached to the button portion 22 that is inserted into the button insertion hole 26 of the device case 1, and the facing surface that is the predetermined first plane is the inner surface of the device case 1.

The contact member 24 is provided with a member 24, and the contact surface of the contact member 24 is slid so as to face the facing surface of the elastic member 23 from a state in which the electrode surface faces the facing surface and is displaced in the surface direction of the facing surface. When it is attached to the inner surface of No. 1, by being guided by the guide portion 25, the electrode surface gradually moves in the direction opposite to the vertical direction of the facing surface while maintaining the state of facing the facing surface. Since the electrode surface is attached so as to be pressed against the opposing surface of the elastic member 23, the assembly work can be improved.

  That is, in the side surface trigger key 11 of this mobile terminal, the contact member 24 is opposed to the facing surface of the elastic member 23 and is slid so as to face the facing surface while being displaced in the surface direction of the facing surface.

By guiding in a direction intersecting with each other, the electrode surface of the contact member 24 can be gradually moved in the direction opposite to the vertical direction of the facing surface while keeping the state parallel to the facing surface of the elastic member 23. As a result, the electrode surface of the contact member 24 can be pressed against the opposing surface of the elastic member 23.

  That is, each of the pair of guide portions 25 includes the guide rail 31 provided in the device case 1 and the slide portion 32 provided in the contact member 24 and guided by the guide rail 31. Since the slide portion 32 provided on the member 24 can be guided by the guide rail 31 provided on the device case 1, the electrode surface of the contact member 24 is gradually approached while keeping the state parallel to the facing surface of the elastic member 23. It is possible to surely and satisfactorily superimpose them.

In the second step, when the contact member 24 is attached to the inner surface of the device case 1, the contact member 24 is guided by the predetermined guide portion 25 so that the electrode surface is kept in the state of facing the facing surface. The assembly work can be improved by gradually moving the contact member 24 in the direction opposite to the direction perpendicular to the facing surface and attaching the electrode surface so as to press the electrode surface against the facing surface of the elastic member 23.

  That is, in the method for manufacturing the side-face trigger key 11 in this mobile terminal, when the contact member 24 is attached to the inner surface of the device case 1 in the second step, the guide member 25 guides the contact member 24 to thereby provide the electrode surface. Since it is possible to gradually move the contact member 24 in a direction opposite to the direction perpendicular to the facing surface while keeping the parallel state with the facing surface, press the electrode surface against the facing surface of the elastic member 23. As a result, the assembling work is simple and easy, and the assembling work can be improved.
