Description

[Technical field]

[0001] The present invention relates to a switch device and a disaster prevention wireless device. [Background technology]

[0002] Push button type switch devices have been proposed in the past. Push button type switch devices are configured to operate a switch element provided in a housing by pressing an operating member, which is a key top exposed from the housing, against a resilient force. As an example of a structure for guiding the up and down movement of such an operating member, Patent Document 1 discloses a push button operation mechanism in which an operating member (operating part) is movably arranged in an opening provided in a design panel. Such a push button operation mechanism is configured so that the operating member can be guided by sliding against the inner edge of the opening even when the operating member is pressed obliquely by a user.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Hereinafter, an embodiment of the present invention will be described with reference to Fig. 1 to Fig. 15. The disaster prevention wireless device 1 shown in Fig. 1 and Fig. 2 is a device that can be used as a disaster prevention device by having a clock function, a function for receiving wireless signals from a radio or disaster prevention wireless device, a lighting function, a power generation function, etc. In the following description of the disaster prevention wireless device 1, the side of the handle 12 shown in Fig. 1 is referred to as the top and the opposite side as the bottom, the side of the speaker 111 is referred to as the front and the opposite side as the rear. In addition, the left side when looking forward from the rear of the disaster prevention wireless device 1 is referred to as the left, and the opposite side as the right.

[0011] The disaster prevention wireless device 1 includes a main body 11 formed in a rectangular box shape, and a handle 12 formed in an arch-shaped (or U-shaped) curved column shape and connected to the upper part of the main body 11. A case 10, which is an exterior member of the main body 11 and the handle 12, is made 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 top and left side of the main body 11. Dial switches S5 and S6 are provided between the slide switch S3 and the slide switch S4 on the left side of the main body 11. 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 right side of the disaster prevention wireless device 1. Furthermore, a push button switch S7 and a push button switch S8 are provided on the top and right side of the main body 11 (see FIG. 2).

[0012] A cover 112, which is a plate member that is roughly bullet-shaped when viewed from the front, is disposed on the front of the disaster prevention wireless device 1. The cover 112 is partially or entirely transparent, and is configured to allow the dial and hands of a clock unit 113 disposed inside the main body unit 11 to be visually confirmed (the configuration of the clock unit 113 is not shown). The clock unit 113 may be configured as a digital clock that displays the time and the like using a liquid crystal display unit. In addition, a channel display unit 114 is provided on the left front side of the disaster prevention wireless device 1.

[0013] A foldable antenna 115 is provided on the rear side of the upper surface of the disaster prevention wireless device 1. The antenna 115 shown in Fig. 1 and other figures is in a stored state, but when in use, it can be raised from the main body 11 and adjusted to an appropriate angle or expanded or contracted so as to increase the reception sensitivity of wireless signals.

[0014] The power generation device 116 and the battery box 14 are disposed on the back of the disaster prevention wireless device 1 shown in Fig. 2. 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 disposed on the back of the main body portion 11. The handle portion 116a in Fig. 2 is shown housed in a recess provided on the back of the main body portion 11, but when generating power, the handle portion 116a can be raised to the side opposite the recess and rotated around the shaft portion 116b to charge the secondary battery housed in the battery box 14 and drive various functions of the disaster prevention wireless device 1.

[0015] On the right side of the disaster prevention wireless device 1, a light source unit L that emits illumination light, jacks J1 and J2 to which communication cables can be connected, and a jack J3 to which the power supply cable of the disaster prevention wireless device 1 can be connected are provided.

[0016] A protrusion 117 extending from front to back is provided on the bottom surface of the disaster prevention wireless device 1. The protrusions 117 are arranged parallel to each other at the left and right positions of the main body 11, so that the disaster prevention wireless device 1 can be stably placed on the placement surface.

[0017] 3 is a rear perspective view of the disaster prevention wireless device 1, with the configuration on the rear case 3 side thereof omitted. The disaster prevention wireless device 1 has a flat circuit board 4 that occupies substantially the entire interior area extending in the vertical and horizontal directions of the main body 11. Switch elements 41 to 48 that detect 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 operating member 5, a switch element 48, and guide parts 21, 31 formed on the inner surfaces of the front case 2 and the rear case 3 (see also FIG. 6). As shown in FIG. 4(a) and FIG. 4(b), the operating member 5 has a short cylindrical operated part 51 formed on the moving axis O of the operating member 5, a guided part 52 formed in a brim-like shape around the outer periphery of the operated part 51, and an operating part 53 capable of operating the switch element 48. The operated part 51 protrudes in the direction of the moving axis O on the opposite side to the operating part 53 (or the switch element 48). The guided part 52 protrudes in a direction different from the moving axis O (in this embodiment, the vertical direction) and is provided in the shape of a long rectangular flat plate. The guided part 52 has a concave cutout part 521 provided at an end 52a on the first direction D1 side and an end 52b on the second direction D2 side opposite to the first direction D1 side. The notch 521 is cut out in a substantially straight line, but the connection edge with the ends 52a, 52b is chamfered in a C-shape to widen the width. The guided portion 52 has a protrusion 522. The protrusion 522 is located near the edge in the short length direction (direction perpendicular 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 to be wider than the inner diameter of the opening 118 when it is housed in the case 10, as shown in FIG. 6.

[0019] As shown in FIG. 4(b), the operation part 53 is provided on the opposite side of the guided part 52 from the operated part 51 side. The operation part 53 is formed in a substantially rectangular tube shape. The switch element 48 has an element body 481 and an input piece 482 provided so as to be linearly movable relative to the element body 481. The input piece 482 is always biased in a direction away from the element body 481 by an internal elastic member such as a coil spring (not shown), and is configured so that its movement is restricted at a predetermined separated position. The input piece 482 of the switch element 48 is engaged in the operation part 53 of the operation member 5. Therefore, when the operation member 5 is pressed toward the element body 481 side, the input piece 482 moves toward the element body 481 side against the elastic force of the elastic member via the operation part 53. The element body 481 detects the movement of the input piece 482 and can cause an input signal to be detected by a control part (a processor such as a CPU or a microcomputer) (not shown) in the disaster prevention wireless device 1.

[0020] An opening 118 is formed on the right side surface of the case 10, in which the operated part 51 of the operating member 5 is disposed. 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 is provided on the inner edge of the opening 118, in which the outer surface side of the case 10 is inclined in a C-shape. The operated part 51 is disposed so as to be movable on a movement axis O located inside the opening 118 during operation.

[0021] As shown in Figs. 5 and 6, the inner surface of the outer wall of the right side surface of the front case 2 and the rear case 3 (case 10) is provided with a guide portion 21 and a guide portion 31, which are flat convex ribs. The guide portions 21 and 31 guide the moving direction of the guided portion 52. The guide portion 21 and the guide portion 31 are provided on the same plane. The guide portion 21 provided on the front case 2 side has an edge portion 211 that restricts the movement of the operating member 5 toward the front case 2 side. The edge portion 211 corresponds to the side edge of the rib (guide portion 21) erected from the front case 2. The guide portion 31 provided on the rear case 3 side has an edge portion 311 that restricts the movement of the operating member 5 toward the rear case 3 side. The edge portion 311 also corresponds to the side edge of the rib (guide portion 31) erected from the rear case 3. The edge portion 211 and the edge portion 311 are arranged approximately parallel to each other. The guide portions 21, 31 are provided so as to be engageable with the notched portion 521 of the guided portion 52, and also regulate the movement of the operating member 5 in the plate surface direction of the guide portions 21, 31. Therefore, the guide portions 21, 31 can guide the operating member 5 in the direction of the movement axis O so as to be able to appear and disappear from the opening 118.

[0022] Furthermore, the guide portion 31 has a restricting portion 312 on the pressing direction side (inside the case 10) parallel to the movement axis O of the operating member 5. The restricting portion 312 protrudes toward the movement axis O side beyond the edge portion 311 of the guide portion 31. In other words, the restricting portion 312 protrudes toward the movement axis O side of the operating member 5 beyond the notch portion 521, and is configured to be able to restrict the movement of the operating member 5 in the pressing direction by abutting against the surface of the guided portion 52 on the operating portion 53 side.

[0023] Here, the operation of the push button switch S8 (switch device) will be described. In FIG. 6, the operating member 5 is constantly biased by the input piece 482 with a predetermined force toward the opening 118. When the user pushes the operating member 5 into the inside of the case 10, the operating member 5 moves along the movement axis O. The operating member 5 is configured so that it can be housed in the case 10 further than the opening 118 when pushed. The movement of the operating member 5 when pushed is restricted by the contact of the guided portion 52 with the restricting portion 312. When the user's pushing operation is released, the operating member 5 moves toward the opening 118 due to the elastic force of the input piece 482.

[0024] With the above-described configuration of the push button switch S8 (switch device), the operating member 5 is guided by the guide parts 21, 31 provided inside the case 10, and thus can stably move along the movement axis O that is coaxial with the central axis of the opening 118. Furthermore, the operating member 5 is guided by the guide parts 21, 31, and thus the operated part 51 is prevented from contacting the inner circumferential surface of the opening 118, and deformation of the opening diameter of the opening 118 due to wear or the like is prevented, and operation can be continued smoothly. Furthermore, since the operating member 5 can stably move along the movement axis O, there is no need to widen the opening diameter of the opening 118 more than necessary, and it is possible to prevent damage to the appearance around the push button switch S8.

[0025] Returning to Fig. 3, the disaster prevention wireless 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 index member 7, a guide portion (first guide portion 25 and second guide portion 92 shown in Figs. 8 and 9(b)) that guides the movement of the index member 7, and the case 10. The case 10 accommodates the index member 7, the guide portion (first guide portion 25 and second guide portion 92) and the switch element 45 therein, and is provided so that a part of the operating 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 includes 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 knurled outer circumferential 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 includes a pinion gear 611 on the rotating shaft 61. The pinion gear 611 is connected to a rack gear 711 of the index member 7 in meshing engagement therewith. Therefore, the position of the index member 7 can be moved in the vertical direction by the user rotating the dial knob 62 of the dial switch S5. The switch element 45 can detect the movement of the index member 7 by the operating member 6.

[0027] 7 and 8, a retaining plate 8, a guide member 9, and an index member 7 are arranged in this order on the front side (front case 2 side) of the circuit board 4 from the rear to the front of the disaster prevention wireless device 1. The movement of the index member 7 in the front-rear and left-right directions is restricted by the front case 2 and the guide member 9, and the index member 7 is provided so as to be slidable in the up-down direction.

[0028] The configuration of the front case 2 will be described with reference to FIG. 9. The front case 2 has a cutout 22 on the left side surface for engaging the operating members of the slide switches S3, S4 and the dial switches S5, S6. A restricting rib 221 having an arc shape when viewed from the left side surface protrudes from the outer surface of the front case 2 corresponding to the dial switches S5, S6. The dial knob 62 of the dial switch S5 (similar to the dial switch S6) that is provided to be rotatable has a restricted rib (not shown) on the outer surface of the front case 2, and is configured to be rotatable within a preset angle range by the restricted rib abutting against an end of the restricting rib 221. In addition, 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 24, which is rectangular in cross section and is formed 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 disposed substantially vertically. The groove 24 extends in the vertical direction with substantially the same cross-sectional shape. The bottom plate 242 is provided with an opening 242a that is elongated and penetrates in the vertical direction parallel to the groove 24 in the form of a slit. The cover 112 described above is also disposed so as to cover the groove 24. The cover 112 is also provided with a window 112a, which is a slit-shaped opening that extends in the vertical direction. The window 112a is disposed in front of the groove 24 and is provided with a length that allows the position of the indicator portion 73 to be visually recognized in the movable range of the indicator member 7.

[0030] As shown in Fig. 9, the bottom plate 242 has a first guide portion 25 that is linear from top to bottom on the inner side (rear side of the disaster prevention wireless device 1) of one bottom plate portion 242b separated by the opening 242a. The first guide portion 25 has a groove portion 251 surrounded by ribs 251a arranged in parallel, and a support surface 252 located rearward of the groove portion 251 (the tip side of the rib 251a). The 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 cutout 251b is provided in a portion of one of the ribs 251a located on the left side of Fig. 9. The front case 2 opens forward and backward at a position corresponding to this cutout 251b, and forms an engagement recess (details not shown) for fixing the cover 112 (see also Fig. 1) installed on the front side. For this reason, the cutout 251b may be omitted when the cover 112 is not provided or depending on the method of fixing the cover 112.

[0032] The support surface 252 is formed on the same plane by the tip surface of the rib 251a and an inner wall 252a provided inside the handle portion 12. The inner wall 252a is surrounded by left and right inner walls 252b, 252c standing in a direction substantially perpendicular to the inner wall 252a. A restricting portion 252d is provided as a protruding portion protruding from the upper end position of the support surface 252 from the inner wall 252a. In other words, the restricting portion 252d is located at the upper end portion of the first guide portion 25.

[0033] Returning to Fig. 8, a sheet-like indexed portion 243 is disposed on the front side of the other bottom plate portion 242c separated by the opening 242a of the bottom plate 242. The indexed portion 243 displays selectable channels (receiving frequencies) in the vertical direction in the disaster prevention wireless device 1. As shown in the front view of part A around the channel display portion 114 in Fig. 1, the user can visually confirm the setting value 243a of the channel (receiving frequency) displayed on the indexed portion 243 from the front side of the disaster prevention wireless device 1 through the window portion 112a. The indexed portion 243 is fixed to the bottom plate portion 242c by any method.

[0034] As shown in FIG. 9, bosses having female screw portions 244 for fixing the guide member 9 are provided at two positions, 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 viewed from the rack gear 711 side. FIG. 10(b) is a perspective view of the indicator member 7 and the guide member 9 as viewed from the opposite side to the rack gear 711. The indicator member 7 has a straight rod-shaped main body 71, a second guided portion 72 connected to the right side surface (second surface) of the main body 71 that is different from the moving direction of the main body 71, and an L-shaped indicator portion 73 connected to the right side surface of the main body 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 or the indicator member 7 may be made of a material having higher rigidity than the other by using a metal material or the like. The main body 71 has a rack gear 711 on the first direction D1 side. The main body 71 has a first guided portion 712 on the opposite side (first surface) of the rack gear 711. Therefore, the index member 7 is formed with a guided portion including a first guided portion 712 provided on the first surface side and a second guided portion 72 provided on a second surface side different from the first guided portion 712. The first guided portion 712 is formed by ribs 712a arranged in two parallel positions. Furthermore, 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. 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 opposite side to the first guided portion 712. That is, the indicator member 7 has the second guided portion 72 provided on the base end side of the indicator portion 73.

[0037] The guide member 9 is formed in a long rod shape and is arranged in parallel with the index member 7. The guide member 9 has a screw hole 91 through which the screw member 90 shown in FIG. 8 can be inserted, and is fixed to the front case 2 by screwing the screw member 90 into the female screw portion 244 of the front case 2. The guide member 9 also has a flat flange-shaped second guide portion 92 protruding on the left side surface side (the index 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 that guides the second guided portion 72 of the index member 7. The second guided portion 72 can slidably come into contact with a protruding portion 921a that is semicircular in cross section and provided on the guide surface 921 side of the second guide portion 92 (see also FIG. 8). The protruding portion 921a is formed along the longitudinal direction of the guide member 9. In addition, a restricting portion 921b protruding beyond the protruding portion 921a is provided on the guide surface 921. The restricting portion 921b comes into contact with an end of the indicator member 7 moving along the guide surface 921 of the second guide portion 92, and restricts the movement of the indicator member 7 to one side (the lower side of the disaster prevention wireless device 1) to set the movement end position.

[0038] 8, the recessed groove portion 251 of the first guide portion 25 restricts movement of the index member 7 in the first direction d1 while slidably engaging and supporting the first guided portion 712. In addition, the second guide portion 92 restricts movement of the index member 7 in a 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 index member 7 (see also FIG. 11). The pressing plate 8 is formed so as to cover most of the movable area of ​​the index member 7, and a part of the protruding portion 8a is disposed within the handle portion 12. By disposing the pressing plate 8 between the circuit board 4 and the index member 7, it is possible to prevent the rack gear 711 from interfering with elements mounted on the circuit board 4 (for example, legs protruding on the opposite side to the mounting surface of the switch element 43 and the switch element 44) even if the index member 7 swings with the movement (see FIG. 11). The pressing plate 8 has a plurality of openings 81 to 83 arranged in series as shown in FIG. 7. The opening 81 is provided by cutting out the side of the pressing plate 8, and is provided as a non-interference portion so as to avoid the meshing position between the pinion gear 611 and the rack gear 711. In addition, openings 82 and openings 83 are provided as non-interference portions to avoid interference with legs protruding from the opposite side to the mounting surface of switch elements 45 and 46 mounted on circuit board 4 shown in FIG. 3 (detailed positional relationship is not shown).

[0040] Next, the operation of the selection device 13 will be described. The indicator member 7 can be moved up and down by the user rotating the dial knob 62. The user can recognize the currently selected setting value 243a from the position on the indexed 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 wireless signal received by the disaster prevention wireless device 1, the channel number or the value of the receiving frequency is displayed in ascending or descending order as the setting value 243a on the indexed portion 243, and the user can recognize the current setting value from the position on the setting value 243a indicated by the indicator portion 73. In addition, the switch element 45 corresponding to the dial switch S5 detects an input value (amount of rotation) corresponding to the setting value 342a indicated by the indicator portion 73. The disaster prevention wireless device 1 can perform processing according to the input value (amount of rotation) detected by the switch element 45 by a control unit not shown.

[0041] The downward movable end position of the indicator member 7 is restricted and set by one end of the second guided portion 72 of the indicator member 7 abutting against the restricting portion 921b. The upward movable end position of the indicator member 7 is restricted and set by the abutting portion 713 of the indicator member 7 abutting against the restricting portion 252d of the front case 2. A part of the indicator member 7 is disposed within the handle portion 12 at one movable end position of the indicator member 7 (in this embodiment, the position where the abutting portion 713 of the indicator member 7 abuts against the restricting portion 252d).

[0042] As described above, the selecting device 13 described in this embodiment can be made in a simple process because the indicator member 7 can be made from the same material as the case 10 (front case 2 and rear case 3) of the disaster prevention wireless device 1 and other parts that make up the disaster prevention wireless device 1. In addition, the indicator member 7 is also disposed inside the handle portion 12 at one of the movable end positions, so the movable range can be widened while miniaturizing the main body portion 11. Therefore, it is possible to configure a disaster prevention wireless device 1 and a selecting device 13 in which the range of the channel display portion 114 is widened while the disaster prevention wireless device 1 is compact, making it easy to see the setting value 243a.

[0043] Next, a description will be given of the battery box 14 provided in the disaster prevention wireless device 1. The disaster prevention wireless device 1 is provided with the battery box 14 including a main body 11 (second member) and a cover member 32 (first member) on the rear side shown in Fig. 2. This battery box 14 includes a release portion 321 (first release portion) provided in the cover member 32 and a release portion 33 (second release portion) provided in the main body 11 (rear case 3), forming a double locking mechanism.

[0044] The rear case 3 has a bottomed recessed storage section 34 capable of storing multiple batteries BT on the rear side (see FIG. 15). A plate-shaped lid member 32 is connected to the main body 11 on the rear side of the storage section 34 by a pivot shaft 323 so as to be openable and closable.

[0045] A release portion 321 is provided on the tip side of the cover member 32 opposite to the pivot shaft 323. As shown in the cross-sectional view (similar to the side view) of FIG. 15, the release portion 321 is formed in a substantially U-shaped cantilever spring plate shape that protrudes from the cover member 32 in the closing direction. Therefore, the release portion 321 is connected to the pivot shaft 323 of the cover member 32 so as to be able to resiliently spring in the radial direction. The release portion 321 also has an operation claw 322 at its tip for performing the release operation of the release portion 321. The operation claw 322 is formed to have a width shorter than the width (left-right width) of the release portion 321 as shown in FIG. 12. An inclined portion 322a is formed at the tip portion on the outer surface side of the operation claw 322. The release portion 321 also has engaged portions 321a at both left and right shoulder portions on the base end side of the operation claw 322 (see also FIG. 5). The engaged portion 321a is cut out in an L-shape and formed in a stepped shape.

[0046] The rear case 3 also has a recess 35 that is capable of housing the release portion 321 and has an engaging portion 351 formed on an inner wall 35a. The engaging portion 351 is formed as a protrusion. The engaging portion 351 formed on the rear case 3 (main body portion 11) is configured to be able to engage with the engaged portion 321a.

[0047] As shown in FIG. 12, the release portion 33 is formed in a rectangular cantilever spring plate shape by cutting out a part of the rear case 3 (main body portion 11). Therefore, the release portion 33 is provided so as to be able to resiliently spring against the rear case 3. The release portion 33 is provided extending toward the operation claw 322 side of the cover member 32. That is, the release portion 33 and the release portion 321 are arranged so that their respective tip portions face each other while partially overlapping each other. The release portion 33 has a protruding portion 331 protruding toward the outer surface side of the rear case 3, and a protruding portion 332 arranged on the tip side of the release portion 33 relative to the protruding portion 331. The protruding portion 331 is formed in a rectangular shape that is long in the width direction of the release portion 33 when viewed from behind, and an inclined portion 331a is provided on the base end side of the release portion 33. The protrusion 331 is arranged in parallel to the operation claw 322 with a gap S (see the enlarged view of part B in FIG. 15) between the protrusion 331 and the tip of the operation claw 322 set to be narrow (for example, narrower than the thickness of the user's finger). In addition, a marker 331b that is recessed in a semispherical concave shape is formed on the top surface (end surface) of the protrusion 331.

[0048] The protruding portion 332 is formed in a rectangular shape that is long in the width direction of the release portion 33 in the rear view of FIG. 12. Moreover, the protruding portion 332 is gently inclined on the base end side of the release portion 33 as shown in the enlarged view of part B in FIG. 15. In the present embodiment, a part of the width direction of the tip of the release portion 33 abuts against the operation claw 322, but the whole of the width direction may abut against the operation claw 322. That is, at least a part of the width direction of the tip of the release portion 33 abuts against the operation claw 322. Moreover, the release portion 33 is provided in a recessed portion 36 recessed from the outer surface 3a of the rear case 3, and when the cover member 32 is in the closed state, the protruding portion 331, the protruding portion 332, and the operation claw 322 are disposed at a position recessed from the outer surface 3a of the rear case 3.

[0049] 13, the releasing portion 33 has a columnar regulated protrusion 333 formed in a hollow, generally cylindrical shape on the inside of the main body 11 (the side opposite to the side on which the protrusion 331 is provided). The regulated protrusion 333 extends toward the inner surface of the opposing front case 2. At the tip of the regulated protrusion 333, a protrusion 333a is formed that protrudes in a semi-cylindrical shape on the tip side of the releasing portion 33. Therefore, the end face of the protrusion 333a is formed in a semi-arc shape.

[0050] As shown in FIG. 14, the front case 2 has a columnar restricting protrusion 26 formed in a T-shape in cross section on the inner side. The restricting protrusion 26 extends toward the inner side of the opposing rear case 3. The restricting protrusion 26 includes a flat horizontal portion 261 and a vertical portion 262 protruding from the middle position in the width direction of the horizontal portion 261 toward the tip side of the release portion 33 (i.e., the lower side of the disaster prevention wireless device 1). A triangular plate-shaped reinforcing rib 263 is provided on the opposite side of the vertical portion 262 of the restricting protrusion 26. The restricting protrusion 26 is disposed so as to penetrate the T-shaped opening 49 of the circuit board 4. The tip of the restricting protrusion 26 is located closer to the restricted protrusion 333 than the circuit board 4. As shown in FIG. 15, the restricting protrusion 26 is substantially opposed to the restricted protrusion 333. The restricting protrusion 26 and the restricted protrusion 333 are disposed parallel to each other on different straight lines.

[0051] Next, the operation of attaching and detaching the cover member 32 of the battery box 14 will be described. The battery box 14 shown in Fig. 15 is fixed in a state in which the engaging portion 351 and the engaged portion 321a are engaged with each other and the cover member 32 covers the storage portion 34. The gap S is set to be narrow, and the release operation of the release portion 321 (first release portion) for the operation claw 322 is hindered by the protruding portion 331 so as to block the entry of a finger or the like, so that the user is prevented from unintentionally releasing the release portion 321. In this way, the release portion 33 is resiliently biased to a position that hinders the release operation for the release portion 321.

[0052] To open the cover member 32, first, the release portion 33 is pushed down toward the main body 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 as a fulcrum. Since the main body 11 has the restricting protrusion 26 at a position where it can abut against the restricted protrusion 333 of the release-operated release portion 33, the movement of the release portion 33 is restricted by the abutment of the restricted protrusion 333 and the restricting protrusion 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 this embodiment, mainly the protruding portion 333a of the restricted protrusion 333 and the vertical portion 262 of the restricting protrusion 26 can abut against each other. When the release portion 33 is pushed down, the gap S is expanded to a width (or space) that allows the tip of a finger to be inserted into the lower surface side of the operation claw 322.

[0053] When the user performs a release operation by pressing operation claw 322 toward cover member 32 (rotation shaft 323) against the elastic force of release portion 321, release portion 321 can be bent until the engagement between engaged portion 321a and engagement portion 351 is released. This releases the lock between cover member 32 and main body 11, and cover member 32 can be rotated around rotation shaft 323 to the open state.

[0054] To close the lid member 32, the lid member 32 is rotated so as to be pushed toward the main body 11. Then, parts of both widthwise edges of the release portion 321 come into contact with the engagement portion 351 and bend. When the release portion 321 climbs over the engagement portion 351 at the position of the engaged portion 321a, it is urged against the inner wall 35a on the engaging portion 351 side, and the engagement portion 351 and the engaged portion 321a are engaged with each other. This allows the lid member 32 and the main body 11 to be easily fixed together.

[0055] In the above, in this embodiment, the battery box 14 (lock mechanism) including the cover member 32 (first member) having the engaged portion 321a, the main body portion 11 (second member) having the engaging portion 351 engageable with the engaged portion 321a, the release portion 321 (first release portion) that releases the engagement between the engaged portion 321a and the engaging portion 351 by a release operation, and the release portion 33 (second release portion) that is resiliently biased to a position that inhibits the release operation for the release portion 321 has been described. The cover member 32 and the main body portion 11 can be fixed by a double lock mechanism using the release portion 321 and the release portion 33. Therefore, it is possible to configure a disaster prevention wireless device 1 that includes a lock mechanism (battery box 14) that can be easily attached and detached while preventing unintentional release.

[0056] Although the embodiment of the present invention has been described above, the present invention is not limited to the embodiment, and various modifications can be made to the embodiment. For example, in the embodiment, the guide parts 21 and 31 are provided directly on the case 10, but the guide parts may be formed of any member housed in the case 10.

[0057] The restricting portion 312 described in this embodiment may be provided on at least one of the guide portion 21 and the guide portion 31, for example, on both the guide portion 21 and the guide portion 31.

[0058] Furthermore, the operation unit 53 capable of operating the switch element 48 is not limited to the configuration shown in this embodiment, but may have any configuration depending on the configuration of the switch element 48.

[0059] In the present embodiment, the curved columnar handle portion 12 is connected to the main body portion 11 at the left and right positions and curved into a U-shape, but 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. The indicator member 7 may be configured such that the entire indicator member 7 is disposed within the handle portion 12 at one of the movable end positions.

[0060] In addition, in this embodiment, the case 10 is configured to accommodate the index member 7, the guide portion (the first guide portion 25 and the second guide portion 92), and the switch element 45 therein, and a portion of the operating member 6 connected to the switch element 45 is exposed to the outside of the case 10; however, any of the index member 7, the guide portion (the first guide portion 25 and the second guide portion 92), the operating member 6, and the switch element 45 may be configured to be partially or entirely accommodated inside the case 10.

[0061] In addition, in the present embodiment, an example has been described in which the device equipped with the selection device 13 is the disaster prevention wireless device 1, but the selection device 13 can be applied to devices having other functions. For example, the selection device 13 may be applied to a device that can select any function or setting in addition to the selection of a channel (receiving frequency).

[0062] In addition, in the battery box 14, the release portion 321 (first release portion) may be provided on the main body portion 11 (second member) side. In this case, the release portion 321 has an engaged portion and is formed to be resiliently resilient, and can be configured to be engageable with and detachable from an engaging portion provided on the cover member 32 side. In addition, the release portion 33 (second release portion) may be provided on the cover member 32 (first member) side.

[0063] Moreover, the engaging portion 351 may be configured as a recess, and the engaged portion 321a may be configured as a protrusion.

[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 protrusion 331 protruding from the outer surface of the release portion 33 and the operating claw 322. However, by providing a recess at the tip of the release portion 33 and positioning the operating claw 322 in this recess, a gap S that blocks the entry of a finger, etc. can be formed by the gap between the inner wall of the recess and the operating claw 322.

[0065] Moreover, in this 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. [Explanation of symbols]
