  FIG. 1 is a perspective view showing an external appearance of a mobile phone 1 according to an embodiment of the present invention in an open state.

  The mobile phone 1 is configured as a so-called foldable mobile phone, and includes a first housing 3 and a second housing 5 that are rotatably connected to each other between an open state and a closed state. The first housing 3 and the second housing 5 are each formed, for example, in a generally thin rectangular parallelepiped shape, and are overlapped with each other in the closed state so that their contours substantially coincide with each other.

  The first housing 3 includes, for example, a front case 21 that constitutes the facing surface portion 3s that faces the second housing 5 in the closed state, and a rear case 23 that constitutes the back side thereof. The front case 21 and the rear case 23 are made of resin, for example, and are fixed to each other with screws. The second housing 5 is configured similarly.

  Although not particularly shown, the first housing 3 is provided with, for example, a microphone for communication, a built-in antenna for communication, a speaker for notification, a camera, and an operation unit 7 that receives user operations. Although not particularly illustrated, for example, a speaker for calling and a display unit 9 are provided in the second housing 5.

  The operation unit 7 includes a plurality of operation members that are exposed to the outside of the first housing 3 in the facing surface portion 3s. The plurality of operation members are various in cooperation with, for example, the slider 11 for turning on / off the power of the mobile phone 1, the plurality of dial keys 13 for receiving input of numbers, characters, and the like, and the display unit 9. A cursor key 15 and a determination key 17 for enabling selection, and a plurality of function keys 19 for starting various functions such as mail.

  The slider 11 is operated by being slid in the horizontal direction (sliding direction) in FIG. For example, when the slider 11 is slid to one side in the sliding direction, the mobile phone 1 is turned on. In addition, when the slider 11 is slid to the other side in the sliding direction, the mobile phone 1 is turned off. Note that the operation members (key tops; 13 to 19) other than the slider 11 are operated by pressing, for example.

  FIG. 2A is an enlarged perspective view showing the periphery of the slider 11 of the mobile phone 1. FIG. 2B is an exploded perspective view around the slider 11 of the mobile phone 1.

  In the vicinity of the slider 11, from the outside of the first housing 3, the slider 11, the front case 21, a waterproof cover 25, an internal member 27 that slides together with the slider 11, a plate 29 for generating a click feeling, and a slider A switch 31 that is turned on and off by 11 slides and a circuit board 33 on which the switch 31 is mounted are arranged in a stacked manner. Hereinafter, the structure including the slider 11 and the switch 31 may be referred to as a switch structure 35.

  The slider 11 is made of, for example, resin. The slider 11 includes, for example, a plate-like portion 11 a and a locking portion 11 b that protrudes from the plate-like portion 11 a to the outside of the first housing 3. The plate-like portion 11a and the locking portion 11b are portions exposed to the outside of the first housing 3 in the facing surface portion 3s. The locking part 11b is formed on a ridge extending in a direction orthogonal to the sliding direction, facilitating the sliding operation by the user.

  The front case 21 has a recess 21a that can accommodate the plate-like portion 11a, and an opening 21b formed at the bottom of the recess 21a.

  The opening 21 b is for enabling the movement (slide) of the slider 11 to be transmitted to the inside of the first housing 3. The opening 21b is formed smaller than the plate-like part 11a. Accordingly, the plate-like portion 11a is supported by the surface of the front case 21 (the bottom surface of the recess 21a).

  The recessed part 21a can adjust the protrusion amount from the opposing surface part 3s of the plate-shaped part 11a by accommodating the plate-shaped part 11a. The recess 21a has, for example, a depth substantially equal to the thickness of the plate-like portion 11a of the slider 11. Moreover, the recessed part 21a can prescribe | regulate the movement of the plate-shaped part 11a. That is, the plate-like portion 11a is fitted in the recess 21a in a direction orthogonal to the slide direction, and is guided in the slide direction by the inner wall surface parallel to the slide direction of the recess 21a. The amount of movement is defined by the difference between the size of the plate-like portion 11a and the size of the recess 21a in the sliding direction.

  The cover 25 is formed of a waterproof and elastic material (for example, rubber). The cover 25 is for preventing moisture from entering from the opening 21b, and is formed wider than the opening 21b. More specifically, the cover 25 is formed, for example, in an oval shape that is larger than the recess 21a. In the center of the cover 25, a press-fitting hole into which a part of the slider 11 (described later) is press-fitted so that the movement (slide) of the slider 11 can be transmitted to the inside of the first housing 3 from the cover 25. 25b is provided.

  The internal member 27 is made of, for example, resin. The internal member 27 is fixed to the slider 11 via the press-fitting hole 25b. Thereby, the internal member 27 suppresses separation between the slider 11 and the cover 25.

  The plate 29 is made of, for example, resin. The plate 29 has a frame portion 29a and two beam portions 29b extending in the sliding direction within the frame portion 29a. The two beam portions 29b are formed with a protrusion 29c that protrudes in the opposite direction of the two beam portions 29b in the vicinity of the center in the sliding direction.

  Between the two beam portions 29b, the first extending portion 27b of the internal member 27 that protrudes toward the plate 29 is fitted to one side or the other side in the sliding direction. The protrusion 29c engages with the first extending portion 27b and suppresses the movement of the first extending portion 27b in the sliding direction. Thereby, the position of the slider 11 is held on one side or the other side in the sliding direction. When a force for sliding the slider 11 is applied to the slider 11 by the user, the first extending portion 27b passes through the protrusion 29c while elastically deforming the two beam portions 29b outward. Thereby, a click feeling is generated.

  The switch 31 is constituted by, for example, a push-type small switch. The switch 31 includes, for example, a thin main body portion 31a and an operated portion 31b protruding from the main body portion 31a. The switch 31 is turned on when the operated portion 31b is pressed, and the pressing is released. Is turned off.

  For example, the switch 31 is disposed so as to be fitted into a notch 29d provided in the plate 29 with the pressing direction directed to the sliding direction. On the other hand, the internal member 27 has a second extending portion 27 c (see FIGS. 3A and 3B) that protrudes to the inside of the first housing 3. Then, when the internal member 27 moves in the sliding direction, the second extending portion 27c presses or releases the operated portion 31b, and the switch 31 is turned on or off.

  The circuit board 33 is configured by a flexible printed wiring board (FPC). The circuit board 33 has flexibility, but can support the switch 31 and the plate 29 by being placed on a shield case (not shown). The circuit board 33 may be formed of a rigid printed wiring board based on a hard resin.

  Fig.3 (a) is sectional drawing in the IIIa-IIIa line | wire of Fig.2 (a). FIG. 3B is a cross-sectional view taken along line IIIb-IIIb in FIG.

  The slider 11 has a guide portion 11c (FIG. 3A), a stopper portion 11d (FIG. 3B), and a knob 11e that protrude from the plate-like portion 11a to the inside of the first housing 3. ing.

  The guide part 11c is provided on the inner side surface of the plate-like part 11a on both sides in the sliding direction, and is formed on a ridge extending in the sliding direction (see also FIG. 2B). The two guide portions 11c are fitted into the opening portion 21b in a direction orthogonal to the sliding direction, and are formed smaller than the opening portion 21b in the sliding direction. Therefore, the two guide portions 11c can guide the slider 11 in the sliding direction by sliding on the inner peripheral surface of the opening 21b.

  The stopper portion 11d is provided on both sides in the sliding direction on the inner surface of the plate-like portion 11a. The interval between the two stopper portions 11d is formed smaller than the size of the opening portion 21b in the sliding direction. The two stopper portions 11d can regulate the amount of movement of the slider 11 by abutting against the inner peripheral surface of the opening 21b in the sliding direction.

  The knob 11 e is a portion that is press-fitted into the aforementioned press-fitting hole 25 b and is fixed to the internal member 27. The knob 11e is formed in an oval shape that is long in the sliding direction, for example.

  The cover 25 includes a seat portion 25s and a packing portion 25a (see also FIG. 2B) that is formed on the outer peripheral edge of the seat portion 25s and protrudes toward the inner surface of the front case 21. The packing portion 25a is press-fitted into a groove portion 21c formed on the inner surface of the front case 21. Thereby, it is suppressed that the water | moisture content which penetrate | invaded from the opening part 21b penetrate | invades into the inside of the 1st housing | casing 3 from the outer periphery of the sheet | seat part 25s.

  The packing part 25a and the groove part 21c are formed in a shape surrounding the opening part 21b, and are preferably provided in an annular shape surrounding the concave part 21a. The shape of the ring may be an appropriate shape such as a rectangle. In this embodiment, the case where the shape of a ring is an oval is illustrated. The widths of the groove portion 21c and the packing portion 25a are appropriately set in consideration of waterproofness and attachment properties. The depth of the groove 21c may be larger, the same as, or smaller than the height of the packing 25a. The packing part 25a and the groove part 21c may be fixed to each other with an adhesive.

  A frame portion 29a of the plate 29 placed on the circuit board 33 is positioned on the inside of the casing of the packing portion 25a, and the removal of the packing portion 25a from the groove portion 21c is suppressed. That is, the distance between the opening surface of the groove portion 21c and the frame portion 29a is set to be smaller than the height of the packing portion 25a.

  The above-described press-fit hole 25b is formed in the center of the sheet portion 25s. The press-fitting hole 25b is formed, for example, in a similar shape to the knob 11e (in the present embodiment, an oval shape) when viewed in the penetrating direction, and is slightly smaller than the knob 11e. When the knob 11e is press-fitted into the press-fitting hole 25b and the knob 11e and the inner peripheral surface of the press-fitting hole 25b are in close contact with each other, moisture that has entered from the opening 21b may enter through the gap between the knob 11e and the press-fitting hole 25b. It is suppressed.

  A thick portion 25c (see also FIG. 2B) is formed around the press-fitting hole 25b. In other words, the press-fitting hole 25b is formed in the thick part 25c. By forming the thick portion 25c, the creeping distance of the press-fitting hole 25b in the penetrating direction is increased, and the adhesion between the knob 11e and the cover 25 is improved. Further, as shown in FIG. 3A, the thick portion 25c is press-fitted between the knob 11e and the guide portion 11c.

  The internal member 27 is fixed to the knob 11e, for example, by inserting the knob 11e into a hole formed in the internal member 27, and suppresses the knob 11e from being removed from the press-fitting hole 25b. The internal member 27 and the knob 11e may be fixed with an adhesive. Moreover, the internal member 27 may clamp the cover 25 with the plate-shaped part 11a or the guide part 11c, and may contribute to waterproofing.

  The operation of the switch structure 35 of the mobile phone 1 having the above configuration will be described.

  As described above, the slider 11 is slidable within the range defined by the plate-like portion 11a and the recess 21a and / or within the range defined by the stopper portion 11d and the opening 21b. Further, as described above, the slider 11 is held by the protrusion 29c of the plate 29 at either one position in the sliding direction or the other position (ON position or OFF position).

  When the knob 11e is positioned between the ON position and the OFF position, the cover 25 prevents the load in the sliding direction from being applied by the knob 11e (the thick portion 25c is in the ON position when the cover 25 is not loaded). The mounting position is set so that it is located between the OFF position and the OFF position. Therefore, as shown in FIG. 3B, when the slider 11 moves to one side in the sliding direction (left side in FIG. 3B), the other side in the sliding direction with respect to the press-fitting hole 25b in the sheet portion 25s. The portion that becomes the side (the right side in FIG. 3B) generates elastic deformation including tensile deformation. Further, a portion of the sheet portion 25s that is on one side in the sliding direction with respect to the press-fitting hole 25b (the left side in FIG. 3B) undergoes elastic deformation including compression deformation. The same applies when the slider 11 moves to the other side in the sliding direction.

  According to the above embodiment, the mobile phone 1 is exposed to the outside of the first housing 3 in the first housing 3 in which the opening portion 21b is formed in the facing surface portion 3s and the facing surface portion 3s. And a slidable slider 11 and a switch 31 provided in the first housing 3 and operated by the slider 11 through the opening 21b. Furthermore, the mobile phone 1 has a cover 25. The cover 25 has water shielding properties and elasticity, and has a sheet portion 25 s facing the opening portion 21 b, and a packing portion that is formed in a shape surrounding the opening portion 21 b in the sheet portion 25 s and is in close contact with the first housing 3. 25a and a thick portion 25c that is provided within a range surrounded by the packing portion 25a in the seat portion 25s, is fixed to the slider 11, and is movable with the slider 11 while being elastically deformed of the seat portion 25s. .

  Therefore, the opening 21b is blocked by the cover 25, and the waterproofness is improved. In the cover 25, since the thick portion 25c can move together with the slider 11 with elastic deformation of the seat portion 25s, the slider 11 can be allowed to slide while maintaining hermeticity. For example, as in the embodiment, when a part of the slider 11 (knob 11e) is press-fitted into the press-fitting hole 25b and the movement of the slider 11 is transmitted to the inside of the cover 25, the thickness is increased by elastic deformation of the sheet portion 25s. The part 25c can be made to follow the knob 11e, and it can suppress that a clearance gap produces between the knob 11e and the thick part 25c. Further, for example, without providing the press-fitting hole 25b, the slider 11 and the thick portion 25c are fixed by an appropriate method (for example, a recess or an adhesive), and the thick portion 25c and the internal member 27 are fixed by an appropriate method. By doing so, the slider 11 can be allowed to slide while maintaining hermeticity.

  In the above embodiment, the mobile phone 1 is an example of the portable electronic device of the present invention, the facing surface portion 3s is an example of the predetermined surface portion of the present invention, and the slider 11 is an example of the operation member of the present invention. The packing part 25a is an example of the close contact part of the present invention, and the thick part 25c is an example of the movable part of the present invention.

(First modification)
FIG. 4 is a perspective view showing a cover 125 according to the first modification.

  The sheet portion 125s of the cover 125 is formed with a wave-shaped wave-shaped portion 125x that travels in the sliding direction in most of the range including the arrangement range of the press-fit holes 25b. In other words, the sheet portion 125s is formed in a shape (bellows shape) that is alternately bent on one surface side and the other surface side with a line extending in a direction orthogonal to the sliding direction as a crease. In FIG. 4, only the side facing the inner side surface of the front case 21 is shown. On the opposite side, the convex in FIG. 4 is concave and the concave in FIG. 125x is visible.

  According to the first modified example described above, the same effects as those of the embodiment can be obtained. Furthermore, since the sheet portion 125s includes a wave-shaped wave portion 125x that travels in the sliding direction of the slider 11, flexibility in the sliding direction of the sheet portion 125s is improved. As a result, as will be described in detail below, improvement in hermeticity and operability can be achieved.

  As in the embodiment, the cover 125 is provided at a position where the other side portion of the sheet portion 125s in the sliding direction than the thick portion 25c undergoes tensile deformation when the slider 11 moves to one side in the sliding direction. It is done. The slider 11 has a knob 11e protruding to the inside of the first housing 3, and a press-fitting hole 25b into which the knob 11e is press-fitted is formed in the thick portion 25c. The wavy portion 125x is provided on the other side (the side on which tensile deformation occurs).

  Accordingly, the knob 11e penetrates the cover 25, and the slider 11 can be fixed to the cover 25 more easily than the embodiment in which the press-fitting hole 25b is not provided (this embodiment is also included in the present invention). 11 and the switch 31 can be simplified. Further, the corrugated portion 125x improves the followability to the knob 11e of the portion of the thick portion 25c opposite to the moving direction of the slider 11 (the side where tensile deformation occurs). In other words, expansion of the press-fitting hole 25b in the sliding direction is suppressed. Therefore, the sealing performance in the knob 11e and the press-fitting hole 25b is improved.

  Similarly to the embodiment of the cover 125, when the slider 11 moves to one side in the sliding direction, the one side portion of the sheet portion 125s in the sliding direction rather than the thick portion 25c is compressed and deformed. Provided in position. The wavy portion 125x is provided on the one side (the side where compression deformation occurs). Therefore, the resistance force of the slider 11 to the slider is reduced, and the operability is improved.

  Note that the wave number, pitch, and wave height of the corrugated portion 125x may be set as appropriate. The wavy portion 125x basically has higher flexibility as the wave number is larger, the pitch is smaller, and the wave height is larger. However, the sheet portion 125s needs to secure a certain thickness, and there is a limit to reducing the pitch. As an example of the wave number and pitch, the size of the seat portion 125s in the sliding direction is about 15 mm, the amount of movement of the slider 11 is about 2 mm, and the size of the press-fitting hole 25b in the sliding direction is about 4 mm (a direction perpendicular to the sliding direction). In the cover 125 having a size of about 1 mm, the wave number is 12 and the pitch is about 1 mm.

(Second modification)
FIG. 5 is a perspective view showing a cover 225 according to a second modification.

  Similarly to the cover 125 according to the first modification, the cover 225 includes a wave-shaped first wave-shaped portion 225x that travels in the sliding direction in the seat portion 225s. However, in plan view, the wavy portion 125x of the first modified example is a straight line in which the wave crest and trough lines are orthogonal to the sliding direction, whereas the first wavy portion 225x of the second modified example is The wave crest and trough lines are formed in an arc shape with the thick portion 25c side concave.

  Similar to the wavy portion 125x of the first modification, the first wavy portion 225x is provided on one side and the other side in the sliding direction (the side on which tensile deformation occurs and the side on which compressive deformation occurs), rather than the thick portion 25c. ing.

  Further, the cover 225 has a wavy second wavy portion 225y that travels in a direction orthogonal to the sliding direction at a position that is lateral to the sliding direction with respect to the thick portion 25c. For example, the second wave portion 225y is formed in a straight line in which the wave crest and trough lines are parallel to the slide direction.

  According to the second modification described above, the same effects as those of the embodiment and the first modification can be obtained. Furthermore, since the wave crest and trough lines are formed in an arc shape with the thick portion 25c side concave in plan view, the followability to the knob 11e in the portion where the tensile deformation of the sheet portion 225s occurs, It is possible to suitably reduce the resistance in the portion where the sheet portion 225s undergoes compressive deformation.

  That is, the stress generated in the sheet portion 225s when the slider 11 is slid is distributed radially around the thick portion 25c. In other words, the isobaric lines of stress are arcuate with the thick portion 25c side being concave. And the absorption of the stress by a deformation | transformation of the 1st wavelike part 225x can be effectively performed because the shape of the wave top and trough line of the 1st wavelike part 225x approaches the shape of the isobaric line.

(Third Modification)
FIG. 6 is a perspective view showing a cover 325 according to a third modification.

  The cover 325 includes a first wavy portion 325x that is substantially similar to the first wavy portion 225x according to the second modification in the seat portion 325s. However, in the second modification, the second wavy portion 225y (that is, the wavy portion provided at a position lateral to the sliding direction with respect to the thick portion 25c) proceeds in a direction orthogonal to the sliding direction. In contrast, in the third modification, the second wavy portion 325y is formed in a wavy shape that proceeds in the sliding direction. The second wavy portion 325y is formed in, for example, a straight line in which the wave crest and trough lines are orthogonal to the sliding direction.

  According to the above third modification, the same effects as those of the embodiment and the first and second modifications can be obtained.

(Fourth modification)
FIG. 7 is a perspective view showing a cover 425 according to a fourth modification.

  In the embodiment, the press-fitting hole 25b, the thick portion 25c, and the knob 11e are formed in an oval shape that is long in the sliding direction in the plan view of the facing surface portion 3s. On the other hand, in the fourth modified example, the press-fitting hole 425b, the thick part 425c, and the knob (not shown) are formed in a perfect circle in a plan view of the facing surface part 3s.

  The shape of the knob 11e and the like of the embodiment has an advantage that it is easy to ensure the strength in the sliding direction of the knob 11e. The fourth modification has an advantage that the force applied to the cover 425 by the knob can be easily dispersed. Accordingly, in consideration of the strength of the material of the slider 11 and the like, the shape of the knob or the like of the fourth modified example or the embodiment may be appropriately adopted.

  The present invention is not limited to the above embodiment, and may be implemented in various aspects.

  The mobile electronic device is not limited to a mobile phone. For example, the portable electronic device may be a PDA, a digital camera, or a game machine. Further, the switch structure is not limited to that included in the portable electronic device. It may be provided in a large electronic device or structure.

  The switch structure is not limited to that for turning the power on and off. For example, the switch structure may switch the operation mode of the electronic device or the display of the display device.

  The embodiment exemplifies a switch structure in which the operation member (11) is operated by the user on both the one side and the other side in the sliding direction, and the operation member is selectively held on both sides in the sliding direction. However, the operation on the switch structure is not limited to this mode. For example, in the switch structure, the operating member is operated only to one side in the sliding direction by the user, and the operating member is automatically returned to the other side by a biasing member such as a spring (the operating member is held at the other side in the sliding direction). May be). Further, for example, the switch structure may be one in which the operation member is automatically returned to the center of the slide range (position holding) by the urging member and selectively operated on both sides in the slide direction by the user.

  The embodiment exemplifies a mode in which the switch is turned on when the operation member is slid to one side, and the switch is turned off when the operation member is slid to the other side. However, ON and OFF of the switch may be appropriately assigned for the slide operation. For example, in the switch structure in which the operation member is operated to one side in the sliding direction and automatically returns to the other side as described above, the switch is turned on and off each time the sliding operation is performed on one side in the sliding direction. It may be performed alternately. Further, for example, in the switch structure in which the operation member is automatically returned to the center of the slide range as described above, when a slide operation is performed on one side in the slide direction, one switch is turned on and the slide operation is performed on the other side. If done, other switches may be turned on.

  In the embodiment, the cover caused tensile deformation and compression deformation when the operation member was slid to either the one side or the other side in the sliding direction. In other words, the cover is provided so as to be unloaded when the operation member is positioned in the middle of the slide range. However, the cover may be appropriately deformed with respect to the slide of the operation member. For example, as described above, in the switch structure in which the operating member is operated to one side in the sliding direction and automatically returns to the other side, the cover is provided so as to be unloaded when the operating member is automatically returned. Also good. In this case, when the operation member is slid to one side in the sliding direction, tensile deformation and compression deformation occur. However, when the operation member is slid to the other side in the sliding direction (automatic return), tensile deformation and compression are generated. Deformation is eliminated.

  The operation member is not limited to the one that operates the switch indirectly through another member (27). For example, the operation member may be in contact with the switch and directly operate the switch. The operation member may be one in which a movable contact constituting a switch is attached to the operation member itself. Although the slider 11 is an example of an operation member, the combination of the slider 11 and the internal member 27 of the embodiment can be regarded as an operation member.

  The operation member may not be configured as a separate member from the cover. For example, the operation member may be configured by forming a protrusion projecting to the outside of the housing in the sheet portion of the cover.

  The cover is not limited to one in which the close contact portion is in close contact with the housing (inside surface) from the inside of the housing, and the cover is in close contact with the housing (outside surface) from the outside of the housing. Good. Further, the close contact portion is not limited to the one that is press-fitted into the groove portion as in the embodiment. For example, the sheet portion is formed flat up to the outer edge (no packing portion is formed), and the outer edge portion (contact portion) of the sheet portion includes an inner surface of the housing and an appropriate member disposed in the housing. It may be sandwiched between. The cover may be a part of another member (for example, a key sheet interposed between the dial key 13 and a pressing switch (not shown) pressed by the dial key 13).

  The switch is not limited to a push type, and may be, for example, a slide type. Further, the switch may be a contact type in which the movable contact and the fixed contact come into contact with or separate from each other, or may be a non-contact type using a photoelectric element or a capacitance element.
