[0010] Hereinafter, based on FIGS. 1 to 15, embodiments of the present invention will be described. The disaster prevention wireless device 1 shown in FIGS. 1 and 2 is a device that can be used as a disaster prevention device equipped with a clock function, a wireless signal reception function such as radio and disaster prevention wireless, a lighting function, a power generation function, and the like. In the following description of the disaster prevention wireless device 1, the side of the handle portion 12 shown in FIG. 1 is set as the upper side, the opposite side is set as the lower side, the side of the speaker 111 is set as the front side, and the opposite side is set as the rear side. Also, the left side when viewing the disaster prevention wireless device 1 from the rear to the front is set as the left side, and the opposite side is set as the right side.
[0011] The disaster prevention wireless device 1 includes a main body 11 formed in a rectangular parallelepiped box shape and a handle 12 formed in an arch-shaped (or U-shaped) curved columnar shape and connected to the upper part of the main body 11. The case 10, which is an exterior member of the main body 11 and the handle 12, is formed of a resin material and is composed of a front case 2 and a rear case 3. A plurality of slide switches S1 to S4 are provided on the upper surface and the left side surface of the main body 11. Also, between the slide switch S3 and the slide switch S4 on the left side surface of the main body 11, dial switches S5 and S6 are provided. For example, the upper dial switch S5 can set the reception frequency of the wireless signal, and the dial switch S6 can set the volume of the sound output from the speaker 111 provided on the front surface on the right side of the disaster prevention wireless device 1. Further, a push button switch S7 and a push button switch S8 are provided on the upper surface and the right side surface (see FIG. 2) of the main body 11.
[0012] On the front surface of the disaster prevention wireless device 1, a cover 112, which is a plate member having a substantially bullet shape in a front view, is arranged. The cover 112 is partially or entirely provided transparently and is configured to enable visual recognition of the dial and the hands of the clock unit 113 arranged inside the main body 11 (the configuration of the clock unit 113 is not shown). Note that the clock unit 113 may be configured as a digital clock that displays the time and the like on a liquid crystal display unit. Also, a channel display unit 114 is provided on the front surface on the left side of the disaster prevention wireless device 1.
[0013] On the rear side of the upper surface of the disaster prevention wireless device 1, a foldable antenna 115 is provided. The antenna 115 shown in FIG. 1 and the like is in a stored state, but during use, it can be raised from the main body 11 and adjusted to an appropriate angle or stretched and deformed so that the reception sensitivity of the wireless signal is increased.
[0014] On the back of the disaster prevention wireless device 1 shown in FIG. 2, a power generation device 116 and a battery box 14 are arranged. On the back of the main body 11, a foldable handle portion 116a of the power generation device 116 and a shaft portion 116b to which the handle portion 116a is connected are arranged. The handle portion 116a in FIG. 2 shows a state of being housed in a recess provided on the back of the main body 11. However, during power generation, the handle portion 116a is lifted to the side opposite to the recess and rotated around the shaft portion 116b, so that the secondary battery housed in the battery box 14 can be charged or various functions of the disaster prevention wireless device 1 can be driven.
[0015] On the right side surface of the disaster prevention wireless device 1, a light source portion L that emits illumination light, jacks J1 and J2 to which a communication cable can be connected, and a jack J3 to which a power supply cable of the disaster prevention wireless device 1 can be connected are provided.
[0016] On the bottom surface of the disaster prevention wireless device 1, a protruding portion 117 extending in the front-rear direction is provided. The protruding portions 117 are arranged to be parallel at the left and right positions of the main body 11, and the disaster prevention wireless device 1 can be stably placed on the placement surface.
[0017] FIG. 3 is a rear perspective view in which the configuration on the rear case 3 side of the disaster prevention wireless device 1 is omitted. The disaster prevention wireless device 1 has a flat circuit board 4 substantially throughout the interior in the vertical and horizontal directions of the main body 11. Switch elements 41 to 48 for detecting inputs to the switches S1 to S8 are mounted on the circuit board 4.
[0018] The push button switch S8 configured as a switch device includes an operation member 5, a switch element 48, and guide portions 21 and 31 formed on the inner surfaces of the front case 2 and the rear case 3 (see also FIG. 6). As shown in FIGS. 4(a) and 4(b), the operation member 5 has a short columnar operated portion 51 formed on the movement axis O of the operation member 5, a guided portion 52 formed in a flange shape around the outer periphery of the operated portion 51, and an operation portion 53 capable of operating the switch element 48. The operated portion 51 protrudes in the direction of the movement axis O on the side opposite to the operation portion 53 (or the switch element 48). The guided portion 52 protrudes in a direction different from the movement axis O (the vertical direction in this embodiment) and is provided in a long rectangular flat plate shape. Further, the guided portion 52 has concave notches 521 provided at an end portion 52a on the first direction D1 side and an end portion 52b on the second direction D2 side opposite to the first direction D1 side. The notch 521 is notched in a substantially straight line, but the connection edges with the end portions 52a and 52b are chamfered in a C-shaped surface and widened. Further, the guided portion 52 has a protruding portion 522. The protruding portion 522 is located near the edge in the short direction (the direction orthogonal to the first direction D1 and the second direction D2) on the surface of the guided portion 52 on the operated portion 51 side. The guided portion 52 is formed wider than the inner diameter of the opening 118 when housed in the case 10 as shown in FIG. 6.
[0019] As shown in FIG. 4(b), the operation portion 53 is provided on the side opposite to the operated portion 51 side of the guided portion 52. The operation portion 53 is formed in a substantially square tube shape. The switch element 48 has an element main body 481 and an input piece 482 provided so as to be linearly movable with respect to the element main body 481. Although not shown, the input piece 482 is constantly biased in the separating direction by an elastic member such as an internal coil spring, and is configured such that its movement is restricted at a predetermined separating position. The input piece 482 of the switch element 48 is engaged in the operation portion 53 of the operation member 5. Therefore, when the operation member 5 is pressed toward the element main body 481 side, the input piece 482 moves toward the element main body 481 side against the elastic force of the elastic member via the operation portion 53. The element main body 481 can detect the movement of the input piece 482 and cause a control portion (a processor such as a CPU or a microcomputer) (not shown) in the disaster prevention radio device 1 to detect an input signal.
[0020] On the right side surface of the case 10, an opening 118 for arranging the operated part 51 of the operation member 5 is formed. The opening 118 is formed in a substantially circular shape following the shape of the outer peripheral side surface of the operated part 51. As shown in FIG. 6, an inclined part 118a in which the outer side surface side of the case 10 is inclined in a C-surface shape is provided on the inner edge of the opening 118. The operated part 51 is arranged movably on a moving axis O located inside the opening 118 during operation.
[0021] Also, as shown in FIGS. 5 and 6, guide parts 21 and 31, which are flat plate-shaped convex ribs, are provided on the inner surfaces of the outer walls of the right side surfaces of the front case 2 and the rear case 3 (case 10), respectively. The guide parts 21 and 31 guide the moving direction of the guided part 52. The guide parts 21 and 31 are provided on the same plane. The guide part 21 provided on the front case 2 side has an edge part 211 that restricts the movement of the operation member 5 toward the front case 2 side. The edge part 211 corresponds to the side edge of a rib (guide part 21) standing upright from the front case 2. Also, the guide part 31 provided on the rear case 3 side has an edge part 311 that restricts the movement of the operation member 5 toward the rear case 3 side. The edge part 311 also corresponds to the side edge of a rib (guide part 31) standing upright from the rear case 3. The edge part 211 and the edge part 311 are arranged substantially in parallel. The guide parts 21 and 31 are provided so as to be engageable with the notch part 521 of the guided part 52, and also restrict the movement of the operation member 5 in the plate surface direction of the guide parts 21 and 31. Therefore, the guide parts 21 and 31 can guide the operation member 5 to protrude and retract with respect to the opening 118 in the moving axis O direction.
[0022] Furthermore, the guide part 31 has a restricting part 312 on the pressing direction side (inside the case 10) parallel to the moving axis O of the operation member 5. The restricting part 312 protrudes on the moving axis O side with respect to the edge part 311 in the guide part 31. In other words, the restricting part 312 protrudes on the moving axis O side of the operation member 5 with respect to the notch part 521, and is configured to be able to restrict the movement of the operation member 5 in the pushing direction by contacting the surface on the operation part 53 side of the guided part 52.
[0023] Here, the operation of the push button switch S8 (switch device) will be described. In FIG. 6, the operation member 5 is constantly biased by the input piece 482 toward the opening 118 side with a predetermined force. When the user pushes the operation member 5 into the inside of the case 10, the operation member 5 moves along the movement axis O. The operation member 5 is configured to be accommodatable inside the case 10 rather than the opening 118 during the pushing operation. The movement of the operation member 5 during the pushing operation is restricted by the contact of the guided portion 52 with the restricting portion 312. When the pushing operation by the user is released, the operation member 5 moves toward the opening 118 side by the elastic force of the input piece 482.
[0024] With the above configuration of the push button switch S8 (switch device), the operation member 5 can be stably moved along the movement axis O coaxial with the central axis of the opening 118 by being guided by the guide portions 21 and 31 provided inside the case 10. Further, by being guided by the guide portions 21 and 31, the operation member 5 can prevent the operated portion 51 from contacting the inner peripheral surface of the opening 118, prevent deformation due to wear of the opening diameter of the opening 118, etc., and can smoothly continue the operation. Furthermore, since the operation member 5 can be stably moved along the movement axis O, it is not necessary to widen the opening diameter of the opening 118 more than necessary, and it is also possible to prevent damage to the appearance around the push button switch S8.
[0025] Returning to FIG. 3, the disaster prevention radio device 1 has a channel (receiving frequency) selection device 13 on the left side surface of the case 10. The selection device 13 includes a dial switch S5, an indicator member 7, a guide portion (the first guide portion 25 and the second guide portion 92 shown in FIGS. 8 and 9(b)) for guiding the movement of the indicator member 7, and the case 10. The case 10 houses the indicator member 7, the guide portion (the first guide portion 25 and the second guide portion 92), and the switch element 45 inside, and is provided so that a part of the operation member 6 connected to the switch element 45 in the dial switch S5 is exposed to the outside from the left side surface of the case 10.
[0026] The dial switch S5 includes an operating member 6 and a switch element 45 that detects the amount of rotation of the operating member 6. The operating member 6 has a rotating shaft 61 connected to the switch element 45 and a circular plate-shaped dial knob 62 connected to the rotating shaft 61 and having a flat knurl on its outer peripheral surface. The switch element 45 is connected to one end of the rotating shaft 61, and the dial knob 62 is connected to the other end of the rotating shaft 61. The operating member 6 has a pinion gear 611 on the rotating shaft 61. The pinion gear 611 is engaged and connected with the rack gear 711 of the indicator member 7. Therefore, when the user rotates the dial knob 62 of the dial switch S5, the position of the indicator member 7 can be moved in the vertical direction. The switch element 45 can detect the movement operation of the indicator member 7 by the operating member 6.
[0027] On the front side of the circuit board 4 (the front case 2 side), as shown in FIGS. 7 and 8, a pressing plate 8, a guide member 9, and an indicator member 7 are arranged in this order from the rear to the front of the disaster prevention wireless device 1. The movement of the indicator member 7 in the front-rear, left-right directions is restricted by the front case 2 and the guide member 9, and it is provided so as to be slidable in the vertical direction.
[0028] Referring to FIG. 9, the configuration on the front case 2 side will be described. The front case 2 has cutouts 22 on the left side surface for engaging the operating members of the slide switches S3, S4 and the dial switches S5, S6. On the outer surface of the front case 2 corresponding to the dial switches S5, S6, a restricting rib 221 in an arc shape when viewed from the left side surface protrudes. The rotatable dial knob 62 of the dial switch S5 (similarly for the dial switch S6) has a restricted rib (not shown) on the outer surface side of the front case 2, and when this restricted rib abuts against the end of the restricting rib 221, it is configured to be rotatable within a preset angular range. Also, a plurality of ribs 23 are formed on the inner surface of the left side surface of the front case 2.
[0029] As shown in FIG. 8, the front case 2 has a groove portion 24 formed in a rectangular cross-section by a side plate 241 and a bottom plate 242 on the front side of the front case 2 and to the right of the rib 23. The side plate 241 and the bottom plate 242 are arranged substantially perpendicular to each other. The groove portion 24 extends in a substantially constant cross-sectional shape in the vertical direction. The bottom plate 242 is provided with an opening 242a that is long in the vertical direction parallel to the groove portion 24 and penetrates in a slit shape. Further, the cover 112 described above is arranged so as to cover the groove portion 24. The cover 112 is also provided with a window portion 112a which is a slit-shaped opening extending in the vertical direction. The window portion 112a is arranged in front of the groove portion 24 and is provided with a length such that the position of the index portion 73 can be visually recognized within the movable range of the index member 7.
[0030] As shown in FIG. 9, inside one bottom plate portion 242b separated by the opening 242a in the bottom plate 242 (the rear side of the disaster prevention wireless device 1), there is a linear first guide portion 25 extending vertically. The first guide portion 25 has a concave groove portion 251 surrounded by ribs 251a arranged in parallel, and a support surface 252 located on the rear side of the concave groove portion 251 (the tip side of the rib 251a). The concave groove portion 251 is provided at a position corresponding to the main body portion 11 in the vertical direction. On the other hand, the support surface 252 is provided at a position corresponding to the main body portion 11 and the handle portion 12 in the vertical direction.
[0031] A notch 251b is provided in a part of one rib 251a located on the left side of FIG. 9. The front case 2 has an opening in the front and rear at a position corresponding to the notch 251b, and forms an engaging recess (details not shown in the figure) for fixing the cover 112 installed on the front side (see also FIG. 1). Therefore, the notch 251b may be omitted depending on whether the cover 112 is provided or the fixing method of the cover 112.
[0032] The support surface 252 is formed on the same plane by the tip surface of the rib 251a and the inner wall 252a provided in the handle portion 12. The inner wall 252a is surrounded by left and right inner walls 252b and 252c standing upright in a direction substantially perpendicular to the inner wall 252a. Further, a regulating portion 252d, which is a protruding portion protruding at the upper end position of the support surface 252, is provided from the inner wall 252a. In terms of reduction, the regulating portion 252d is located at the upper end portion of the first guide portion 25.
[0033] Returning to FIG. 8, on the front side of the other bottom plate portion 242c of the bottom plate 242 separated by the opening 242a, a sheet-like indicatored portion 243 is disposed. The indicatored portion 243 displays the channels (receiving frequencies) selectable in the disaster prevention radio device 1 in the vertical direction. As shown in the front view of part A around the channel display portion 114 in FIG. 1, the user can visually recognize the set value 243a of the channel (receiving frequency) displayed on the indicatored portion 243 through the window portion 112a from the front side of the disaster prevention radio device 1. The indicatored portion 243 is fixed to the bottom plate portion 242c by an arbitrary method.
[0034] Also, as shown in FIG. 9, bosses having female screw portions 244 for fixing the guide member 9 are provided at two locations, upper and lower, on the inner side (rear side) of the bottom plate portion 242c.
[0035] FIG. 10(a) is a perspective view of the indicator member 7 and the guide member 9 as seen from the side of the rack gear 711. FIG. 10(b) is a perspective view of the indicator member 7 and the guide member 9 as seen from the side opposite to the rack gear 711. The indicator member 7 has a straight rod-shaped main body portion 71, a second guided portion 72 connected to the right side surface (second surface) different from the moving direction of the main body portion 71, and an L-shaped indicator portion 73 connected to the right side surface of the main body portion 71 so as to be aligned with the second guided portion 72. The indicator member 7 is formed of the same resin material as the case 10 (front case 2 and rear case 3). Note that either one of the case 10 and the indicator member 7 can be made of a material with higher rigidity, such as a metal material, than the other. The main body portion 71 has a rack gear 711 on the first direction D1 side. Further, the main body portion 71 is provided with a first guided portion 712 on the side of the surface (first surface) opposite to the rack gear 711. Therefore, the guided portion formed on the indicator member 7 includes the first guided portion 712 provided on the first surface side and the second guided portion 72 provided on the second surface side different from the first guided portion 712. The first guided portion 712 is formed by ribs 712a arranged in two parallel locations. Further, a protruding portion having a width shorter than the width of the main body portion 71 protrudes from one end side in the longitudinal direction of the main body portion 71, and a contact portion 713 is provided at the tip of this protruding portion. The contact portion 713 is formed in a flat surface shape.
[0036] The second guided portion 72 is formed in a flat flange shape. Further, the indicator portion 73 extends toward the first guided portion 712 side with respect to the main body portion 71, and a rod-shaped tip portion 731 is formed in a direction substantially perpendicular to the side opposite to the first guided portion 712. That is, the indicator member 7 is provided with the second guided portion 72 on the base end side of the indicator portion 73.
[0037] The guide member 9 is formed in a long rod shape and arranged parallel to the indicator member 7. The guide member 9 has a screw hole 91 through which the screw member 90 shown in FIG. 8 can be inserted. The guide member 9 is fixed to the front case 2 by screwing the screw member 90 to the female screw portion 244 of the front case 2. Further, the guide member 9 has a flat plate flange-shaped second guide portion 92 protruding on the left side surface side (the indicator member 7 side). The surface of the second guide portion 92 on the front case 2 side (the fastening direction side) is formed as a guide surface 921 for guiding the second guided portion 72 of the indicator member 7. Note that the second guided portion 72 can slidably contact a protruding portion 921a having a semi-circular arc shape in a cross-sectional view provided on the guide surface 921 side of the second guide portion 92 (see also FIG. 8). The protruding portion 921a is formed over the longitudinal direction of the guide member 9. Further, a regulating portion 921b protruding more than the protruding portion 921a is provided on the guide surface 921. The regulating portion 921b contacts an end portion of the indicator member 7 moving along the guide surface 921 of the second guide portion 92, and regulates the movement of the indicator member 7 to one side (the lower side of the disaster prevention radio device 1) to set the movement end position.
[0038] As shown in FIG. 8, the concave groove portion 251 of the first guide portion 25 regulates the movement of the indicator member 7 in the first direction d1 while slidably engaging and supporting the first guided portion 712. Further, the second guide portion 92 regulates the movement of the indicator member 7 in the second direction d2 opposite to the first direction d1 while slidably supporting the second guided portion 72.
[0039] The pressing plate 8 shown in FIG. 7 is formed in a flat plate shape and is disposed between the circuit board 4 and the indicator member 7 (see also FIG. 11). The pressing plate 8 is formed to cover most of the movable region of the indicator member 7, and some protruding portions 8a are disposed within the handle portion 12. By disposing the pressing plate 8 between the circuit board 4 and the indicator member 7, even when the indicator member 7 swings as it moves, it is possible to prevent the rack gear 711 from interfering with an element mounted on the circuit board 4 (for example, a leg portion protruding from the mounting surface of the switch elements 43 and 44 on the opposite side) (see FIG. 11). The pressing plate 8 has a plurality of openings 81 to 83 provided in series as shown in FIG. 7. The opening 81 is provided by notching the side of the pressing plate 8 and is provided as a non-interference portion so as to avoid the meshing position of the pinion gear 611 and the rack gear 711. Further, the openings 82 and 83 are provided as non-interference portions to avoid interference with the leg portions protruding from the opposite side of the mounting surfaces of the switch elements 45 and 46 mounted on the circuit board 4 shown in FIG. 3 (the detailed positional relationship is not shown).
[0040] Next, the operation of the selection device 13 will be described. The indicator member 7 can move up and down when the user rotates the dial knob 62. The user can recognize the currently selected set value 243a based on the position on the indicated portion 243 indicated by the indicator portion 73 of the indicator member 7 (see also the front view of part A in FIG. 1). For example, when the setting selected by the selection device 13 is the channel (receiving frequency) of the radio signal received by the disaster prevention radio device 1, the channel number or the receiving frequency value is displayed in ascending or descending order as the set value 243a on the indicated portion 243, and the user can recognize the current set value based on the position on the set value 243a indicated by the indicator portion 73. Further, the switch element 45 corresponding to the dial switch S5 detects an input value (rotation amount) corresponding to the set value 342a indicated by the indicator portion 73. The disaster prevention radio device 1 can perform processing according to the input value (rotation amount) detected by the switch element 45 by a control unit (not shown).
[0041] The downward movable end position of the indicator member 7 is regulated and set by the contact of one end of the second guided portion 72 of the indicator member 7 with the regulating portion 921b. Further, the upward movable end position of the indicator member 7 is regulated and set by the contact of the contact portion 713 of the indicator member 7 with the regulating portion 252d of the front case 2. A part of the indicator member 7 is disposed within the handle portion 12 at one of the movable end positions of the indicator member 7 (in this embodiment, the position where the contact portion 713 of the indicator member 7 contacts the regulating portion 252d).
[0042] As described above, the selection device 13 described in this embodiment can be created from the same material as the case 10 (front case 2 and rear case 3) of the disaster prevention radio device 1 or other components constituting the disaster prevention radio device 1, so that the selection device 13 can be created in a simple process. Further, since the indicator member 7 is also disposed within the handle portion 12 at one of the movable end positions, the movable range can be widened while reducing the size of the main body portion 11. Therefore, it is possible to configure a disaster prevention radio device 1 and a selection device 13 that are compact while enlarging the range of the channel display portion 114 and making the set value 243a easy to view.
[0043] Next, the battery box 14 provided in the disaster prevention radio device 1 will be described. The disaster prevention radio device 1 includes a battery box 14 including a main body portion 11 (second member) and a lid member 32 (first member) on the back side shown in FIG. 2. This battery box 14 includes a release portion 321 (first release portion) provided on the lid member 32 and a release portion 33 (second release portion) provided on the main body portion 11 (rear case 3) to form a double locking mechanism.
[0044] The rear case 3 includes a bottomed concave accommodating portion 34 capable of accommodating a plurality of batteries BT on the back side (see FIG. 15). A plate-shaped lid member 32 is connected to the main body portion 11 so as to be openable and closable by a rotation shaft 323 on the rear side of the accommodating portion 34.
[0045] On the tip side opposite to the rotation axis 323 of the lid member 32, a release portion 321 is provided. As shown in the cross-sectional view of FIG. 15 (the side view is the same), the release portion 321 is formed in a substantially U-shaped cantilever spring plate shape that protrudes in the closing direction with respect to the lid member 32. Therefore, the release portion 321 is elastically connected in the radial direction with respect to the rotation axis 323 of the lid member 32. Further, the release portion 321 has an operation claw 322 at the tip for performing the release operation of the release portion 321. As shown in FIG. 12, the operation claw 322 is formed with a shorter width than the width (left-right width) of the release portion 321. An inclined portion 322a is formed at the tip of the outer surface side of the operation claw 322. Further, the release portion 321 has engaged portions 321a at both left and right shoulder portions on the proximal end side of the operation claw 322 (see also FIG. 5). The engaged portion 321a is formed in a stepped shape by being notched in an L shape.
[0046] Further, the rear case 3 has a recess 35 which is a depression capable of accommodating the release portion 321 and in which an engaging portion 351 is formed on the inner wall 35a. The engaging portion 351 is formed as a convex portion. The engaging portion 351 formed in the rear case 3 (main body portion 11) is configured to be engageable with the engaged portion 321a.
[0047] As shown in FIG. 12, the release portion 33 is formed in a rectangular cantilever spring plate shape with a part of the rear case 3 (main body portion 11) cut out. Therefore, the release portion 33 is provided elastically with respect to the rear case 3. The release portion 33 extends toward the operation claw 322 side of the lid member 32. That is, the release portion 33 and the release portion 321 are arranged so that the tip portions thereof face each other while partially overlapping. The release portion 33 has a protruding portion 331 protruding to the outer surface side of the rear case 3 and a protruding portion 332 arranged on the tip side of the release portion 33 rather than the protruding portion 331. The protruding portion 331 is formed in a long rectangular shape that is long in the width direction of the release portion 33 in a rear view, and an inclined portion 331a is provided on the proximal end side of the release portion 33. The protruding portion 331 sets the gap S (see the enlarged view of portion B in FIG. 15) with the tip of the operation claw 322 to be narrow (for example, narrower than the thickness of the user's finger) and is arranged in parallel with the operation claw 322. Further, a marker 331b recessed in a hemispherical shape is formed on the top surface (end surface) of the protruding portion 331.
[0048] The protruding portion 332 is formed in a long rectangular shape that is long in the width direction of the release portion 33 in the rear view of FIG. 12. Further, as shown in the enlarged view of portion B in FIG. 15, the protruding portion 332 is gently inclined on the proximal end side of the release portion 33. In the release portion 33 of the present embodiment, a part of the width direction at the tip abuts on the operation claw 322, but it may abut on the operation claw 322 over the entire width direction. That is, at least a part of the width direction at the tip of the release portion 33 abuts on the operation claw 322. Further, the release portion 33 is provided in a recessed portion 36 that is recessed from the outer surface 3a of the rear case 3. In the closed state of the lid member 32, the protruding portion 331, the protruding portion 332, and the operation claw 322 are arranged at a position recessed from the outer surface 3a of the rear case 3.
[0049] As shown in FIG. 13, the release portion 33 has a columnar regulated protrusion 333 formed in a substantially cylindrical shape with a hollow interior on the inner side of the main body portion 11 (the side opposite to the surface on which the protruding portion 331 is provided). The regulated protrusion 333 extends toward the inner surface side of the opposing front case 2. At the tip of the regulated protrusion 333, a protruding portion 333a protruding in a semi-cylindrical shape is formed on the tip side of the release portion 33. Therefore, the end face of the protruding portion 333a is formed in a semi-circular arc shape.
[0050] Further, as shown in FIG. 14, the front case 2 has a columnar regulating protrusion 26 formed in a T-shaped cross section on the inner surface side. The regulating protrusion 26 extends toward the inner surface side of the opposing rear case 3. The regulating protrusion 26 includes a flat horizontal portion 261 and a vertical portion 262 protruding from the intermediate position in the width direction of the horizontal portion 261 toward the tip side of the release portion 33 (that is, the lower side of the disaster prevention radio device 1). A triangular plate-shaped reinforcing rib 263 is provided on the side opposite to the vertical portion 262 of the regulating protrusion 26. Further, the regulating protrusion 26 is arranged so as to penetrate through the opening 49 that is opened in a T-shape in the circuit board 4. The tip of the regulating protrusion 26 is located on the side of the regulated protrusion 333 with respect to the circuit board 4. Further, as shown in FIG. 15, the regulating protrusion 26 is substantially opposed to the regulated protrusion 333. The regulating protrusion 26 and the regulated protrusion 333 are arranged in parallel on different straight lines.
[0051] Next, the attachment and detachment operation of the lid member 32 of the battery box 14 will be described. The battery box 14 shown in FIG. 15 is fixed in a state where the engaging portion 351 and the engaged portion 321a are engaged and the lid member 32 covers the accommodating portion 34. The gap S is set to be narrow, and the release operation of the operating claw 322 of the release portion 321 (first release portion) is inhibited by the protruding portion 331 from preventing the entry of a finger or the like, so that it is possible to prevent the user from accidentally releasing the release portion 321. Thus, the release portion 33 is elastically biased to a position that inhibits the release operation of the release portion 321.
[0052] To open the lid member 32, first, the release portion 33 is pushed down toward the main body portion 11 against the elastic force. Then, as shown by the two-dot chain line, the tip side of the release portion 33 moves downward with the base end portion as a fulcrum. Since the main body portion 11 has the regulating projection 26 at a position where it can contact the regulated projection 333 of the release portion 33 that has been released, the movement of the release portion 33 is regulated by the contact of the regulated projection 333 and the regulating projection 26. Therefore, the pushing amount of the release portion 33 can be set within a predetermined allowable range to prevent damage to the release portion 33. In the configuration of the present embodiment, mainly, the protruding portion 333a of the regulated projection 333 and the vertical portion 262 of the regulating projection 26 can come into contact. When the release portion 33 is pushed down, the gap S is widened to a width (or space) that allows the tip of a finger to be inserted on the lower surface side of the operating claw 322.
[0053] When the user presses the operating claw 322 against the elastic force of the release portion 321 toward the lid member 32 side (rotation shaft 323 side) to perform a release operation, the release portion 321 can be bent until the engagement between the engaged portion 321a and the engaging portion 351 is released. Thereby, the lock between the lid member 32 and the main body portion 11 is released, and the lid member 32 can be rotated around the rotation shaft 323 to an open state.
[0054] To close the lid member 32, the lid member 32 is rotated so as to be pushed into the main body 11 side. Then, a part of both edges in the width direction of the release portion 321 abuts against the engaging portion 351 and bends. When the release portion 321 gets over the engaging portion 351 at the position of the engaged portion 321a, the release portion 321 is biased against the inner wall 35a on the engaging portion 351 side, and the engaging portion 351 and the engaged portion 321a are engaged. Thereby, the lid member 32 and the main body 11 are easily fixed.
[0055] As described above, in the present embodiment, the battery box 14 (locking mechanism) including the lid member 32 (first member) having the engaged portion 321a, the main body 11 (second member) having the engaging portion 351 engageable with the engaged portion 321a, the release portion 321 (first release portion) for releasing the engagement between the engaged portion 321a and the engaging portion 351 by a release operation, and the release portion 33 (second release portion) elastically biased to a position that inhibits the release operation on the release portion 321 has been described. The lid member 32 and the main body 11 can be fixed by a double locking mechanism by the release portion 321 and the release portion 33. Therefore, it is possible to configure the disaster prevention wireless device 1 provided with a locking mechanism (battery box 14) that can be easily attached and detached while preventing unintentional release.
[0056] As described above, the embodiments of the present invention have been described, but the present invention is not limited to the present embodiments and can be implemented with various modifications. For example, in the present embodiment, the guide portions 21 and 31 are shown as being directly provided on the case 10, but the guide portions may be configured by any member housed in the case 10.
[0057] Further, the restricting portion 312 described in the present embodiment may be configured to be provided on at least one of the guide portion 21 and the guide portion 31, such as being provided on both the guide portion 21 and the guide portion 31.
[0058] Further, the operation portion 53 capable of operating the switch element 48 is not limited to the configuration shown in the present embodiment and can be any configuration according to the configuration of the switch element 48.
[0059] In addition, in the present embodiment, the curved columnar handle portion 12 is described as being connected to the main body portion 11 at the left and right positions and being curved in a U shape. However, the handle portion 12 may be configured such that one end side is connected to the main body portion 11 and the other end side is not connected to the main body portion 11. Further, the indicator member 7 may be configured such that all of the indicator member 7 is disposed within the handle portion 12 at one movable end position.
[0060] In addition, in the present embodiment, the case 10 is provided so as to house the indicator member 7, the guide portions (the first guide portion 25 and the second guide portion 92), and the switch element 45 therein and expose a part of the operation member 6 connected to the switch element 45 outside the case 10. However, for any configuration of the indicator member 7, the guide portions (the first guide portion 25 and the second guide portion 92), the operation member 6, and the switch element 45, a part or all of them may be configured to be housed inside the case 10.
[0061] In addition, in the present embodiment, an example in which the device including the selection device 13 is the disaster prevention radio device 1 has been described. However, the selection device 13 can be applied to devices having other functions. For example, the selection device 13 may be applied to a device capable of selecting an arbitrary function or setting in addition to selecting a channel (receiving frequency).
[0062] In addition, in the battery box 14, the release portion 321 (the first release portion) may be provided on the main body portion 11 (the second member) side. In this case, the release portion 321 has an engaged portion and is formed to be elastically deformable, and can be configured to be engageable and disengageable with the engaging portion provided on the lid member 32 side. Further, the release portion 33 (the second release portion) may be provided on the lid member 32 (the first member) side.
[0063] Further, the engaging portion 351 may be configured as a concave portion and the engaged portion 321a may be configured as a convex portion.
[0064] In addition, the gap S that can be formed between the release portion 321 and the release portion 33 is formed by the gap between the protruding portion 331 protruding from the outer surface of the release portion 33 and the operation claw 322. However, a concave portion may be provided at the tip of the release portion 33, and the operation claw 322 may be disposed in this concave portion. Thus, the gap S that blocks the entry of a finger or the like may be configured by the gap between the inner wall of the concave portion and the operation claw 322.
[0065] In addition, in the present embodiment, the case 10 has been described as an exterior member, but it may be configured as a case for other positions or functional parts, such as being provided as an interior member.
