The swelling portion 17 is provided in an upper part of the inner peripheral surface of the ring-shaped flange portion 21 in a swelling state in a dome shape. The bulging portion 17 is formed in a dome shape having a small thickness and being easily elastically deformed.

  As a result, as shown in FIGS. 3 and 4, the swelling portion 17 protrudes toward the inner end 11 a of the cylindrical storage portion 11 located inside the lower case 3, and The portion 11 is configured to close the inner end 11a side. In this case, the bulging portion 17 has a thick pressing portion 17a formed at the center thereof so as to project vertically.

  For this reason, as shown in FIGS. 3 and 4, the bulging portion 17 elastically pushes up the operating portion 12 housed in the cylindrical housing portion 11 by the pressing portion 17 a, and lowers the upper end surface of the operating portion 12 to the lower side. The case 3 is configured to be pressed against the periphery of the through hole 15. The bulging portion 17 is configured to be elastically deformed when the operation portion 12 is pressed from above so as to switch the key contact portion 14 as a switch contact portion.

Have been. The movable contact 24 is configured to be separated from the pair of fixed contacts 23 when the bulging portion 17 elastically returns and pushes up the operation portion 12.

Next, the operation of the reset switch unit 10 in such a portable terminal will be described.
First, a case where the switch unit 10 is incorporated in the lower case 3 will be described. In this case, the operation unit 12 is stored in a tubular storage unit 11 formed integrally with the lower case 3 so as to be vertically slidable.

  In this state, the tubular portion 16 of the cover member 13 is mounted on the outer periphery of the tubular storage portion 11 from the inner end 11a side of the tubular storage portion 11 located inside the lower case 3. At this time, the tubular portion 16 is elastically pushed open and attached to the outer peripheral surface of the tubular storage portion 11. Then, the press contact portion 19 provided on the upper end surface of the thick portion 18 of the tubular portion 16 is brought into contact with the inner end 11a of the tubular storage portion 11, and the bulging portion 17 of the cover member 13 is moved to the tubular storage portion. 11 within the inner end 11a.

  Thus, in a state where the pressure contact portion 19 of the cylindrical portion 16 is elastically crushed against the inner end portion 11a of the cylindrical storage portion 11, that is, in a state where the cylindrical portion 16 is elastically compressed and pressed, the cylindrical portion 16 is pressed. A plurality of rows of pressure contact protrusions 20 provided in an annular shape are pressed against the outer peripheral surface of the cylindrical storage portion 11 while being elastically compressed and deformed.

  In this state, the plurality of rows of press contact protrusions 20 are pressed against the outer peripheral surface of the cylindrical storage portion 11 in a state where the outer peripheral surface of the cylindrical storage portion 11 is tightened. For this reason, the cylindrical portion 16 is mounted on the outer peripheral surface of the cylindrical storage portion 11 so that the cylindrical portion 16 does not come off from the outer peripheral surface of the cylindrical storage portion 11. Thereby, the inclination of the tubular portion 16 due to the detachment of the tubular portion 16 from the tubular storage portion 11 is prevented, and the attachment state of the tubular portion 16 to the tubular storage portion 11 is stabilized.

  In this case, the plurality of rows of the pressure contact protrusions 20 are formed in a substantially circular cross section that protrudes from the inner peripheral surface and the outer peripheral surface of the cylindrical portion 16. Therefore, the arc-shaped portion 20 b protruding from the inner peripheral surface of the cylindrical portion 16 is strongly pressed against the outer peripheral surface of the cylindrical storage portion 11 by the arc-shaped portion 20 b protruding from the outer peripheral surface of the cylindrical portion 16. .

  Thereby, the plurality of rows of the pressure contact protrusions 20 are formed in a state where the arc-shaped portion 20a protruding from the inner peripheral surface of the cylindrical portion 16 is elastically crushed, that is, elastically compressed and deformed. It is strongly tightened and pressed against the outer peripheral surface of the cylindrical storage portion 11. Therefore, the cylindrical portion 16 is securely and firmly mounted on the outer peripheral surface of the cylindrical storage portion 11. Thereby, the inner end 11a of the cylindrical storage portion 11 is sealed by the cover member 13, so that waterproofness is ensured.

  In this state, the bulging portion 17 of the cover member 13 is elastically bulging into a dome shape, so that the operating portion 12 housed in the cylindrical housing portion 11 is pushed up by the elastic force of the bulging portion 17. Then, the upper end surface of the operation unit 12 is elastically pressed against the periphery of the through hole 15 of the lower case 3. Thereby, in a state where the upper end surface of the operation unit 12 covers the through hole 15 of the lower case 3, a part of the upper end surface of the operation unit 12 passes through the through hole 15 from the lower case 3 to the rear surface side (the upper surface side in FIG. 3). ).

  In this state, since the bulging portion 17 of the cover member 13 is elastically bulging in a dome shape, the key contact portion 14 provided on the lower surface of the pressing portion 17a located inside the bulging portion 17 is movable. The contact 24 is separated from the pair of fixed contacts 23 on the substrate 22 provided on the lower surface of the cover member 13. As a result, the key contact portion 14 is turned off.

Next, the operation of the reset switch unit 10 will be described.
In this case, a thin rod-shaped member (not shown) is inserted into the through hole 15 of the lower case 3 from the outside, and the operation unit 12 is pushed against the elastic force of the bulging portion 17 of the cover member 13. Then, as shown in FIG. 5, the bulging portion 17 of the cover member 13 is pushed by the operation portion 12 and is elastically deformed.

  At this time, since the cylindrical portion 16 is in pressure contact with the outer peripheral surface of the cylindrical storage portion 11 by the plurality of rows of pressure contact protrusions 20, as shown in FIG. Even when the cylindrical portion 16 is pushed and elastically deformed, the cylindrical portion 16 does not fall out of the outer peripheral surface of the cylindrical storage portion 11, and the inclination of the cylindrical portion 16 due to the removal of the cylindrical portion 16 with respect to the cylindrical storage portion 11 is suppressed. Then, the attachment state of the tubular portion 16 to the tubular storage portion 11 is stabilized, and this stable state is maintained.

  When the bulging portion 17 of the cover member 13 is elastically deformed by being pushed by the operating portion 12, as shown in FIG. 5, the movable portion provided on the lower surface of the pressing portion 17a located in the bulging portion 17 is provided. The contact 24 comes into contact with the pair of fixed contacts 23 on the substrate 22 disposed below the cover member 13 to make the pair of fixed contacts 23 conductive. Thereby, the key contact portion 14 is turned on.

  When the operation of pressing the bulging portion 17 of the cover member 13 by the operation unit 12 is released, the bulging portion 17 of the pressed cover member 13 elastically returns to the initial state, as shown in FIG. . Then, the operation unit 12 is pushed up, and the movable contact 24 is separated from the pair of fixed contacts 23. As a result, the key contact section 14 is turned off, and the operation section 12 returns to the initial state.

  As described above, according to the reset switch unit 10 of the portable terminal device, the lower case 3 in which the cylindrical storage unit 11 that slidably stores the operation unit 12 is provided, and the lower case 3 The cylindrical contact portion 16 is mounted on the outer periphery of the cylindrical housing portion 11 and the key contact portion 14 is elastically deformed when the operating portion 12 is pressed in a state where the cylindrical housing portion 11 is closed. A cover member 13 having a bulging portion 17, and a plurality of rows of press contact projections 20 that are annularly pressed against the outer peripheral surface of the cylindrical storage portion 11 are provided on the cylindrical portion 16 of the cover member 13. This makes it possible to ensure waterproofness with a simple structure.

  That is, in the reset switch unit 10, in a state where the operation unit 12 is stored in the cylindrical storage unit 11 provided in the lower case 3, the cylindrical unit 16 of the cover member 13 , The structure is simple, the cover member 13 can be easily and easily attached to the cylindrical storage portion 11, and a plurality of rows provided annularly on the cylindrical portion 16 of the cover member 13. Since the cover member 13 can be reliably pressed against the outer peripheral surface of the cylindrical storage portion 11 by the press contact projection portion 20, the waterproof property can be ensured.

  In this case, since the cylindrical portion 16 is pressed against the outer peripheral surface of the cylindrical storage portion 11 by the plurality of rows of the pressure contact projections 20, the cylindrical portion 16 is prevented from coming off the outer peripheral surface of the cylindrical storage portion 11. As a result, it is possible to prevent the cylindrical portion 16 from tilting due to the tubular portion 16 coming out of the cylindrical storage portion 11, whereby the mounting state of the cylindrical portion 16 with respect to the cylindrical storage portion 11 is always kept constant. Can be stabilized. For this reason, when assembling the switch section 10, it is possible to prevent the cover member 13 from being attached to the cylindrical storage section 11 from being unevenly attached, and to secure stable waterproof performance.

  As a result, in the reset switch unit 10, the bulging portion 17 of the cover member 13 elastically pushes up the operating unit 12 while closing the tubular storage unit 11 and is pushed by the operating unit 12. In this case, the operation portion 12 can be slid smoothly and satisfactorily in the tubular storage portion 11 in accordance with the elastic deformation of the bulging portion 17.

  In this case, the cover member 13 is formed by integrally forming the tubular portion 16, the bulging portion 17, and the plurality of press-contact protrusions 20 with an elastic material such as a silicone resin, a urethane resin, or an elastomer. 13 can be easily and easily manufactured, and the tubular portion 16 of the cover member 13 can be easily elastically pushed out and attached to the outer periphery of the tubular storage portion 11. It can be easily and easily attached to the cylindrical storage portion 11.

  Further, each of the plurality of rows of the pressure contact protrusions 20 is formed in a substantially circular cross section projecting from the inner peripheral surface and the outer peripheral surface of the cylindrical portion 16 of the cover member 13. When the cylindrical portion 16 is mounted on the outer periphery of the cylindrical storage portion 11, the arc-shaped portion 20 b protruding from the outer peripheral surface of the cylindrical portion 16 causes the arc-shaped portion 20 a protruding from the inner peripheral surface of the cylindrical portion 16 to become cylindrical. It can be pressed strongly against the outer peripheral surface of the shape-like storage portion 11.

  For this reason, the plurality of rows of the pressure contact projections 20 are arranged such that the arc-shaped portion 20a protruding from the inner peripheral surface of the cylindrical portion 16 is elastically crushed, that is, elastically compressed and deformed. Since the outer peripheral surface of the storage section 11 can be strongly tightened, a plurality of rows of the press contact projections 20 can be pressed against the outer peripheral surface of the cylindrical storage section 11. Thereby, the cylindrical portion 16 can be securely and firmly attached to the outer peripheral surface of the cylindrical storage portion 11, so that the inner end portion 11 a of the cylindrical storage portion 11 can be securely sealed by the cover member 13. It is possible to further improve the waterproofness.

  Further, the cover member 13 is provided with the press-contact portion 19 which presses the inner end portion 11a of the cylindrical storage portion 11 so that the cylindrical portion 16 of the cover member 13 is mounted on the outer peripheral surface of the cylindrical storage portion 11. Then, the press contact portion 19 of the tubular portion 16 can be pressed against the inner end 11a of the tubular storage portion 11, whereby the press contact portion 19 of the tubular portion 16 can be pressed into the inner end portion of the tubular storage portion 11. Since it is possible to make pressure contact with the elastic member 11a in a state where it is elastically crushed, that is, in a state where it is elastically compressed and deformed, it is possible to further enhance the waterproofness.

  In this case, since the thick portion 18 is formed at the lower portion of the cylindrical portion 16 located inside the lower case 3 so as to protrude into the cylindrical portion 16, the cylindrical portion 16 is housed in the cylindrical shape. When mounted on the outer peripheral surface of the portion 11, the upper end surface of the thick portion 18 can be elastically contacted with the inner end portion 11a of the tubular storage portion 11, and the upper end surface of the thick portion 18 is pressed against the upper end surface. Since the upper end surface of the thick portion 18 elastically contacts the inner end portion 11a of the cylindrical storage portion 11, the press contact portion 19 is securely pressed against the inner end portion 11a of the cylindrical storage portion 11. Can be done.

  Further, in the reset switch section 10, the key contact section 14 is provided with a board 22 disposed below the cover member 13 corresponding to the bulging section 17, and provided on the board 22 so as to correspond to the bulging section 17. And a movable contact 24 provided on the bulging portion 17 and in contact with the pair of fixed contacts 23 so as to be able to come into contact with and separate from the pair of fixed contacts 23. When the protrusion 17 is pressed and elastically deformed, the key contact portion 14 can be reliably and satisfactorily switched.

  That is, when the bulging portion 17 of the cover member 13 is pressed and elastically deformed by the operating portion 12, the key contact portion 14 connects the movable contact 24 provided in the bulging portion 17 to the pair of fixed contacts 23. Since the movable contacts 24 can make contact, the pair of fixed contacts 23 can be made conductive, whereby the key contact portion 14 can be reliably turned on to output an electric signal as an ON signal.

  Further, when the pressing force of the operation unit 12 against the bulging portion 17 of the cover member 13 is released, the key contact portion 14 is elastically returned to the original shape. Can be reliably separated from the pair of fixed contacts 23, so that the conductive state of the pair of fixed contacts 23 by the movable contact 24 can be released. It can be turned off quickly and satisfactorily.

  In the above-described embodiment, the case where the cover member 13 is formed of an elastic material that does not transmit light has been described.
