Description

[Technical Field]

[0001] The present invention relates to a slide switch structure and an electric device, and more particularly to a slide switch structure having a drip-proof function. [Background technology]

[0002] In recent years, with the development of electrical devices with a drip-proof function, technology related to a drip-proof slide switch has been developed. For example, Patent Document 1 below discloses a slide switch structure with a drip-proof function by including an annular valve that covers the opening of the slide switch. The annular valve is formed on the periphery of the slide key where the operating part is provided, and the bending reaction force of the annular valve seals off the water between the slide key and the housing. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2013-256965 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the above-mentioned conventional technology, the annular valve is integrally formed with the operating part, so the annular valve moves as the operating part moves. In order to stop water from entering the opening to the other end when the operating part moves to one end of the opening in the longitudinal direction, the length of the annular valve needs to be longer than the length of the opening in the longitudinal direction. This requires an installation space longer than the length of the opening, which creates the problem of having to make the housing larger.

[0005] An object of one aspect of the present invention is to provide a slide switch structure that is drip-proof against water and chemicals such as alcohol, and that can realize a compact housing. [Means for solving the problem]

[0006] In order to solve the above problems, a slide switch structure according to one embodiment of the present invention comprises a groove portion that penetrates the surface of a housing, an operation knob that is movably attached along the groove portion, and a slide switch that is arranged inside the housing, wherein the slide switch comprises a switch body and a movable lever that are arranged in a position that does not overlap with the groove portion, and the movable lever is engaged with the operation knob inside the housing so that it moves in conjunction with the operation knob. [Effects of the Invention]

[0007] According to one aspect of the present invention, it is possible to provide a slide switch structure that is drip-proof against water and chemicals such as alcohol, and that can realize a compact housing. [Brief explanation of the drawings]

[0009] [Embodiment 1] <Communication equipment> A first embodiment of the present invention will be described in detail below with reference to the drawings. The following description will be based on an example in which an electrical device according to the present invention is applied to a communication device 10 installed at a counter or the like. However, the present invention is not limited to this example, and can also be applied to devices such as audio equipment that have various slide switches with a drip-proof function.

[0010] First, the communication device 10 will be described with reference to Fig. 3 to Fig. 5. Fig. 3 is a diagram illustrating an example of a communication system 1 including the communication device 10 to which the slide switch structure according to the first embodiment is applied.

[0011] As shown in Fig. 3, in recent years, shielding materials 20 such as acrylic panels or vinyl sheets have been installed at counters and other locations to prevent droplet infection of viruses and the like. When shielding materials 20 are installed at counters and other locations, conversations are held across the shielding materials 20, making it difficult for people to hear each other's voices. Even when shielding materials 20 are installed, communication systems 1 are installed at counters and other locations to make it easier for people to hear each other's voices.

[0012] The communication system 1 includes a pair of communication devices 10 and a communication cable 13 , and the pair of communication devices 10 is made up of a master device 11 and a slave device 12 .

[0013] Base unit 11 is equipped with a microphone 111 and a speaker 112, and is installed, for example, near counter representative 21. On the other hand, handset 12 is equipped with a microphone 121 and a speaker 122, and is installed, for example, near customer 22. Communication cable 13 connects base unit 11 and handset 12, performs communication between base unit 11 and handset 12, and supplies power from base unit 11 to handset 12.

[0014] Base unit 11 converts the voice P of counter attendant 21 detected by microphone 111 into a voice signal Pa and transmits it to handset 12 located on the other side of shielding material 20 via communication cable 13. Handset 12, which receives voice signal Pa, converts voice signal Pa into voice P and outputs it from speaker 122.

[0015] Meanwhile, the handset 12 converts the voice Q of the customer 22 detected by the microphone 121 into a voice signal Qa and transmits it to the base unit 11 located on the other side of the shielding material 20 via the communication cable 13. The base unit 11, which receives the voice signal Qa, converts the voice signal Qa into a voice Q and outputs it from the speaker 112.

[0016] As a result, even if the shielding material 20 is installed, the counter attendant 21 and the customer 22 can easily hear the voices P and Q of the other person separated by the shielding material 20 from the speakers 112 and 122 respectively placed nearby.

[0017] The counter may be, for example, a counter at a city hall, a Hello Work office, a station, etc. It is not limited to these, and may be any place other than a counter as long as two people can have a face-to-face conversation. Two or more handsets may also be connected to enable conversation between three or more people.

[0018] 4 is a diagram showing an example of a perspective view of base unit 11. As shown in FIG. 4, base unit 11 includes microphone 111, speaker 112, microphone ON / OFF button 113, power ON / OFF button 114, volume adjustment button 115, slide switch 5, and housing 6.

[0019] The microphone ON / OFF button 113 is a button for switching the microphone ON and OFF, and the slide switch 5 is a switch for adjusting the volume of the speaker 112 by sliding the operation knob 51.

[0020] The volume adjustment button 115 is a button for adjusting the gain of the microphone 111 on the side of the base unit 11. By providing the volume adjustment button 115 on the base unit 11 and allowing the counter attendant 21 to adjust the gain of the microphone 111, the volume of the audio P output from the speaker 122 of the handset 12 can be adjusted. As a result, even if the customer 22 is unfamiliar with operating the handset 12, for example, the counter attendant 21 can adjust the volume of the speaker 122 of the handset 12 by operating the volume adjustment button 115.

[0021] Power ON / OFF button 114 and volume adjustment button 115 are arranged on the side of base unit 11 so that they are at approximately the same height position as slide switch 5 on the front side of base unit 11. Therefore, even if the buttons on the side are not visible when viewed from the front side, the user can guess the approximate positions of power ON / OFF button 114 and volume adjustment button 115 from the position of slide switch 5. This allows the user to easily operate power ON / OFF button 114 and volume adjustment button 115.

[0022] 5 is a diagram showing an example of a front view and a side view of the base unit 11 and the handset 12. The view indicated by the reference numeral 5A is a front view of the base unit 11, the view indicated by the reference numeral 5B is a side view of the base unit 11, the view indicated by the reference numeral 5C is a front view of the handset 12, and the view indicated by the reference numeral 5D is a side view of the handset 12. As shown in FIG. 5, the handset 12 also has a slide switch, similar to the base unit 11.

[0023] As shown in the drawings indicated by the reference numerals 5C and 5D, the handset 12 includes a microphone 121, a speaker 122, a microphone ON / OFF button 123, a slide switch 5, and a housing 6. The handset 12 has the same configuration as the base unit 11, except that it does not include a power ON / OFF button and a volume adjustment button. The power of the handset 12 can be turned ON / OFF on both the base unit 11 and the handset 12 side by operating the power ON / OFF button 114 on the base unit 11 side.

[0024] Furthermore, the slide switch 5 can adjust the volume of the speaker 122 by sliding the operation knob 51. As described above, the volume of the speaker 122 of the handset 12 is adjusted in principle by operating the volume adjustment button 115 on the base unit 11. However, the customer 22 can also adjust the volume of the speaker 122 by sliding the operation knob 51 on the slide switch 5.

[0025] As a result, for example, when the customer 22 is at a counter such as a Hello Work office and does not want others to hear his or her private consultation, the customer 22 can turn down the volume of the speaker 122 by operating the counter.

[0026] (Water-resistant function due to placement of communication equipment) Before and after using the communication system 1, the communication device 10 is disinfected with a disinfectant such as alcohol to prevent contact infection of viruses and the like from the communication device 10. The communication device 10 is disinfected by spraying the disinfectant onto the communication device 10 or wiping it with a cloth or the like impregnated with the disinfectant.

[0027] The slide switch 5 of the communication device 10 has an opening (groove) 54 (see FIG. 2) formed therein into which the operation knob 51 is inserted. If a disinfectant enters the inside of the communication device 10 through the opening 54 during disinfection, there is a possibility that the electronic components inside may be damaged. Furthermore, if the communication device 10 is installed on a window or the like that is exposed to wind and rain, there is a risk that rainwater, dust, and the like may enter through the opening 54.

[0028] 6A and 6B are diagrams showing an example of a cross-sectional view and an internal perspective view of communication device 10. The diagram indicated by reference numeral 6A is a cross-sectional view showing a state in which microphone 111 and speaker 112 are attached to base unit 11. The diagram indicated by reference numeral 6B is a perspective view of the inside of base unit 11 showing a state in which microphone 111b is attached to rear cabinet 62 of base unit 11.

[0029] As shown in the diagrams indicated by the reference numerals 6A and 6B, the microphone 111 includes a pair of microphones 111a and 111b. The microphone 111a is attached to the front cover 61 at a position facing the counter representative 21 so as to mainly detect the voice of the counter representative 21, including surrounding sounds. The microphone 111b is a microphone used for noise cancellation, and is attached to the rear cabinet 62 away from the position facing the counter representative 21 so as to mainly detect surrounding sounds.

[0030] The speaker 112 is attached to the rear cabinet 62 so as not to come into contact with the microphones 111a and 111b.

[0031] The microphones 111a and 111b and the speaker 112 are attached above the slide switch 5 so as to prevent the disinfectant solution or the like that may enter through the opening (groove) 54 of the slide switch 5 (see FIG. 2) from adhering to them.

[0032] As a result, even if the disinfectant or the like that has entered through opening 54 flows downward due to gravity, it is possible to prevent the disinfectant or the like from adhering to microphone 111 and speaker 112 because microphone 111 and speaker 112 are located above opening 54. This makes it possible to prevent damage to microphone 111, speaker 112, etc. by the disinfectant or the like.

[0033] In order to prevent the intrusion of disinfectants, rainwater, and the like through the opening 54, the communication device 10 further includes a slide switch 5 having a drip-proof function. The drip-proof function of the slide switch 5 will be described in detail below.

[0034] <Slide switch structure> Fig. 1 is an example of a perspective view of slide switch 5 as seen from inside housing 6, and Fig. 2 is an example of a front view. For ease of explanation, the following will describe slide switch 5 provided in master unit 11, but slide switch 5 provided in slave unit 12 also has the same configuration as master unit 11.

[0035] As shown in FIGS. 1 and 2, the slide switch 5 includes an operation knob 51, an opening (groove) 54, a switch body 52, a movable lever 53, an operation knob holder 511, and a slide switch substrate 7.

[0036] Opening 54 is a groove that penetrates housing 6, and is formed, for example, as an elongated groove extending in the left-right direction on housing 6 on the front side of communication device 10. Opening 54 is not limited to this, and may, for example, extend in the up-down direction or diagonally, or may form a gentle curve.

[0037] The operation knob 51 is inserted into the opening 54 from the outside of the housing 6 and attached so as to be movable along the opening 54. As described above, the operation knob 51 is a switch that adjusts the volume output from the speaker 112. For example, sliding the operation knob 51 to the leftmost position minimizes the volume, and sliding it to the rightmost position maximizes the volume. Conversely, the volume may be maximized when sliding the operation knob 51 to the leftmost position and minimized when sliding it to the rightmost position.

[0038] The operation knob holding portion 511 holds the operation knob 51 from the inside of the housing 6 so that the operation knob 51 can move stably along the opening 54. The operation knob holding portion 511 is formed with an insertion hole 511a (see FIG. 9) through which a locking piece 512 of the operation knob 51 is inserted, as will be described later.

[0039] The switch body 52 is attached to the inner wall of the housing 6 and is the main body of the slide switch 5 disposed inside the housing 6. As will be described in detail later, the switch body 52 is disposed at a position that does not overlap with the opening 54 and is spaced apart from the opening 54 so that dust, disinfectant, and the like will not adhere to the switch body 52 even if they enter through the opening 54. In the first embodiment, the switch body 52 is disposed above the opening 54.

[0040] The slide switch board 7 is disposed above the switch body 52, in contact with or in close proximity to the switch body 52. ​​As a result, the slide switch board 7 is attached above the opening 54, just like the switch body 52, and damage to the slide switch board 7 due to the adhesion of disinfectant or the like can be prevented.

[0041] Movable lever 53 is locked by a locking piece 512 formed on operation knob 51 inside housing 6 so as to move in conjunction with operation knob 51. When operation knob 51 is operated by a user, movable lever 53 locked by locking piece 512 moves in conjunction with operation knob 51, allowing slide switch 5 to be operated.

[0042] <Lock the movable lever with the operating knob> Next, the locking of movable lever 53 by operation knob 51 will be described in detail with reference to Fig. 7 to Fig. 9. Fig. 7 is a perspective view showing an example of operation knob 51, Fig. 8 is an example of a perspective view showing a portion of slide switch 5 cut away, and Fig. 9 is an example of a cross-sectional view.

[0043] (Operation knob) As described above, the operation knob 51 is inserted into the opening 54 from the outside of the housing 6 so as to be movable along the opening 54 .

[0044] As shown in FIGS. 7 to 9, the operation knob 51 includes a grip portion 514 and a locking piece 512.

[0045] The grip portion 514 is located on the outside of the housing 6, and is the portion that the user touches when operating the operation knob 51. The locking piece 512 is located in the opening 54 and inside the housing 6.

[0046] The locking piece 512 has a base end 512a and a free end 512b formed continuous with the base end 512a. The base end 512a is located in the opening 54 and moves along the opening 54. The free end 512b has a pair of clamping ends 513 that are located inside the housing 6 and lock the movable lever 53. The pair of clamping ends 513 has clamping ends 513a and 513b.

[0047] The pair of clamping ends 513 have a generally trapezoidal shape overall, tapering toward the tip. Clamping ends 513a, 513b are formed such that angles θ1, θ2 between inclined surfaces 513c, 513d and lines L1, L2 generally parallel to opening 54 are greater than 45 degrees, giving them pointed tips.

[0048] This allows the pair of clamping ends 513 to be easily inserted into the insertion holes 511a of the operation knob holding portion 511 arranged inside the housing 6.

[0049] The pair of clamping ends 513 clamps the movable lever 53 by inserting it between clamping end 513a and clamping end 513b. When the user slides the operation knob 51, the pair of clamping ends 513 connected to the operation knob 51 also move, and the movable lever 53 clamped between the pair of clamping ends 513 also moves. This allows the movable lever 53 to move in conjunction with the operation knob 51.

[0050] The pair of clamping ends 513 are formed so that the distance w between clamping end 513a and clamping end 513b is approximately the same length as the width of movable lever 53. This allows movable lever 53 to be firmly clamped by the pair of clamping ends 513, making it less likely to rattle.

[0051] Furthermore, clamping end 513a and clamping end 513b are configured to have different lengths from base end 512a, for example, clamping end 513a is formed longer than clamping end 513b. As a result, when inserting movable lever 53 between clamping end 513a and clamping end 513b, movable lever 53 can be pressed against the tip of longer clamping end 513a to slightly widen gap w, and then slid toward base end 512a for insertion. Therefore, even if gap w is approximately the same as the width of movable lever 53, movable lever 53 can be easily inserted.

[0052] Furthermore, since the lengths of the two are different, it is possible to prevent the operation knob 51 from being inserted into the opening 54 in the wrong orientation during assembly. Furthermore, it is possible to omit the step of checking the orientation of the operation knob 51, thereby improving production efficiency.

[0053] (Thin plate-shaped locking piece) The locking piece 512 is formed in the shape of a thin plate having a small thickness (t: see FIG. 9) in the width direction (short direction) of the opening 54. The locking piece 512 is formed, for example, from a synthetic resin or the like, and has a thickness t of approximately 0.8 mm to 1.5 mm. The locking piece 512 may also be made of a metal or the like with a chemical-resistant coating formed thereon.

[0054] Forming locking piece 512 in a thin plate shape makes it possible to reduce the width of opening 54 into which locking piece 512 is inserted. This makes it possible to prevent dust, disinfectant, and the like from entering the inside of housing 6 through opening 54. Furthermore, when the width of opening 54 is reduced, it becomes difficult to see the inside of housing 6 through opening 54, which makes it possible to prevent the aesthetic appearance of communication device 10 from being impaired.

[0055] A protective sheet 81, which will be described later, is attached to the opening 54 from the inside of the housing 6. This further improves the drip-proof and dust-proof effects and makes it difficult to see inside the housing 6. The protective sheet 81 will be described in detail later.

[0056] (Switch body position) Here, the locking of the movable lever 53 by the pair of clamping ends 513 will be described in more detail.

[0057] 8 and 9, switch body 52 is disposed above opening 54. Movable lever 53 is disposed so as to protrude downward from the underside of switch body 52. ​​Movable lever 53 is locked near opening 54 at a predetermined angle θ3 by a pair of clamping ends 513 extending from the opening 54 side.

[0058] In the first embodiment, the predetermined angle θ3 is approximately 90 degrees, and the movable lever 53 is locked so as to form an angle of 90 degrees with respect to the pair of clamping ends 513. This allows the switch main body 52 to be arranged at an angle that follows the front cover 61 of the housing 6, thereby making the housing 6 more compact. This also allows the switch main body 52 to be arranged above the opening 54 (at a position that does not overlap with the opening (groove) 54).

[0059] By attaching the switch body 52 above the opening 54, even if the disinfectant or the like that has entered through the opening 54 flows downward due to gravity or flows down along the operation knob 51, etc., it can be prevented from adhering to the switch body 52. ​​This more reliably prevents damage to the switch body 52, etc., due to the disinfectant or the like. Note that the predetermined angle θ3 may be an angle other than 90 degrees as long as it is different from the angle at which the pair of clamping ends 513 extend.

[0060] (Locked by a pair of clamping ends) As described above, movable lever 53 is inserted between clamping end 513a and clamping end 513b and locked. In other words, movable lever 53 is not fixed to locking piece 512 with a fastening member such as a screw, and there is a slight clearance between movable lever 53 and locking piece 512. This allows the slide switch to operate without hindrance even if the vertical position or angle of movable lever 53 is slightly misaligned.

[0061] <Protective sheet> As shown in Fig. 10, a protective sheet 81 is attached to the opening 54 so as to cover the opening 54 from the inside of the housing 6. Fig. 10 is a diagram illustrating an example of how to attach the protective sheet 81.

[0062] Protective sheet 81 has slit 811 through which operation knob 51 is inserted and which is movable along opening 54. The width of slit 811 is formed to be even smaller than the width of opening 54, so that intrusion of disinfectant solution and the like through opening 54 can be more reliably prevented.

[0063] Furthermore, by attaching the protective sheet 81, the inside of the housing 6 becomes difficult to see through the opening 54, which further prevents the aesthetic appearance of the communication device 10 from being impaired.

[0064] Protective sheet 81 is made of a fluororesin sheet such as PTFE (polytetrafluoroethylene). PTFE is chemical resistant, so protective sheet 81 does not deform or discolor even when it comes into contact with a disinfectant or the like. Therefore, a disinfectant such as alcohol can be sprayed onto communication device 10 without damaging protective sheet 81.

[0065] Furthermore, since PTFE has a low coefficient of friction, operation knob 51 can be moved smoothly along slit 811.

[0066] PTFE is non-sticky and cannot be attached with adhesive or double-sided tape, so protective sheet 81 is attached to opening 54 with adhesive sheet 82 made of PET (polyethylene terephthalate) or the like with double-sided tape 822 on the top and bottom.

[0067] More specifically, protective sheet 81 is attached by placing protective sheet 81 between opening 54 and adhesive sheet 82 and attaching adhesive sheet 82 with double-sided tape 822. Protective sheet 81 has slit 821 through which operation knob 51 is inserted and which is movable along opening 54.

[0068] <Protective cover> A protective cover 9 is attached within the movable range of the slide switch 5 so that the cable 200 of the connector 100 and the like are not caught in the operation of the slide switch 5.

[0069] The protective cover 9 will be described with reference to Figures 11 and 12. Figure 11 is a perspective view showing an example of the protective cover 9 for the slide switch 5, and Figure 12 is a schematic diagram showing an example of the state in which the protective cover 9 is attached.

[0070] 11, protective cover 9 is made of a transparent sheet material and has mounting holes 91 and cutouts 92. Mounting holes 91 are holes for attaching the top of protective cover 9 to the inside of housing 6 with screws 93 or the like, and cutouts 92 are cutouts for drawing cables 200 and the like out onto protective cover 9.

[0071] 12, protective cover 9 is arranged to cover the movable range of slide switch 5 so that cable 200 and the like do not get caught in the operation of slide switch 5. For example, cable 200 is arranged within the movable range of slide switch 5, and there is a risk that cable 200 will get caught when movable lever 53 or the pair of clamping ends 513 move through opening 54.

[0072] For this reason, the cable 200 is pulled out from the notch 92 formed in the protective cover 9 and placed on top of the protective cover 9. This separates the cable 200 from the slide switch 5 with the protective cover 9, preventing the cable 200 from getting tangled.

[0073] Furthermore, even if a liquid such as a disinfectant enters through the opening 54, the entering liquid adheres to the protective cover 9 and flows downward along the protective cover 9, thereby preventing the liquid from adhering to electronic components, etc.

[0074] The protective cover 9 is made of a flexible, transparent sheet material such as synthetic resin, and the upper part is attached to the inside of the housing 6 with screws 93 or the like.

[0075] Therefore, when the protective cover 9 is attached, the protective cover 9 deforms to fit the surrounding shape, so that the protective cover 9 can be placed well even in a small space inside the housing 6. Furthermore, even if the protective cover 9 comes into contact with and rubs against the movable lever 53 or the like during operation, it does not interfere with the operation of the slide switch 5 because it flexibly deforms to fit the surrounding shape.

[0076] Furthermore, because the protective cover 9 is transparent, when checking the operation of the slide switch 5, the operation of the slide switch 5 can be visually confirmed with the protective cover 9 attached. Even if the cable 200 or the like becomes entangled, the situation can be confirmed through the protective cover 9. Furthermore, although the upper part of the protective cover 9 is fixed with screws or the like, the lower part of the protective cover 9 is not fixed, so that the entangled cable 200 or the like can be removed by rolling up the lower part of the protective cover 9.

[0077] [Embodiment 2] A slide switch 5 according to a second embodiment of the present invention will be described with reference to the drawings. For ease of explanation, members having the same functions as those described in the above embodiment will be denoted by the same reference numerals, and their description will not be repeated. The same applies to a third embodiment and subsequent embodiments.

[0078] Fig. 13 is an example of a perspective view of a slide switch 5 according to embodiment 2. As shown in Fig. 13, the slide switch 5 according to embodiment 2 differs from embodiment 1 in that the opening 54 is formed to be elongated in the vertical direction.

[0079] For example, the slide switch 5 has a structure in which the volume is minimized when the operation knob 51 is slid all the way up, and maximized when it is slid all the way down. Conversely, the slide switch 5 may have a structure in which the volume is maximized when it is slid all the way up, and minimized when it is slid all the way down.

[0080] The switch body 52 is disposed, for example, on the right side of the opening 54 when viewed from inside the housing 6. However, this is not limiting, and the switch body 52 may be disposed on the left side of the opening 54.

[0081] Movable lever 53 is disposed so as to protrude leftward from the left side surface of switch body 52. ​​Movable lever 53 is clamped at a predetermined angle near opening 54 by a pair of clamping ends 513 extending from the opening 54 side.

[0082] Movable lever 53 has a base end 53a, an inclined portion 53c, and a free end 53b. Base end 53a is located higher than free end 53b, and free end 53b extends substantially horizontally and is clamped by a pair of clamping ends 513. Inclined portion 53c has an inclined surface that slopes upward from free end 53b toward base end 53a.

[0083] Since the inclined portion 53c is inclined upward, even if the disinfectant or the like that has entered through the opening 54 flows downward due to gravity or flows down the operation knob 51 or the like, it can be prevented from adhering to the switch body 52 along the inclined portion 53c. This makes it possible to prevent damage to the switch body 52 or the like by the disinfectant or the like.

[0084] [Embodiment 3] Next, a slide switch 5 according to a third embodiment of the present invention will be described with reference to the drawings.

[0085] Fig. 14 is an example of a perspective view of a slide switch 5 according to embodiment 3. As shown in Fig. 14, the slide switch 5 according to embodiment 3 differs from embodiment 2 in that the movable lever 53 is formed to be inclined entirely upward from the free end 53b toward the base end 53a.

[0086] Since the movable lever 53 is formed to be inclined upward, even if the disinfectant or the like that has entered through the opening 54 flows downward due to gravity or flows down the operation knob 51, etc., it can be prevented from adhering to the switch body 52 along the movable lever 53. This makes it possible to prevent damage to the switch body 52, etc., by the disinfectant or the like.

[0087] [Embodiment 4] Next, a slide switch 5 according to a fourth embodiment of the present invention will be described with reference to the drawings.

[0088] 15 is an example of a perspective view of the slide switch 5 according to embodiment 4. The view indicated by reference numeral 15A is an example of a perspective view of the slide switch 5, and the view indicated by reference numeral 15B is an example of a perspective view of only the slide switch 5.

[0089] As shown in the drawings indicated by the reference numerals 15A and 15B, the slide switch 5 according to the fourth embodiment differs from the third embodiment in that the switch body 52 is attached at an angle to the housing 6. Here, an example will be described in which the switch body 52 is disposed on the right side of the opening 54 when viewed from inside the housing 6 and is attached at an angle toward the upper left side, but the switch body 52 may also be disposed on the left side and be angled toward the upper right side.

[0090] Movable lever 53 is disposed so as to protrude leftward from the left side surface of switch body 52. ​​Movable lever 53 is clamped at clamping position P near opening 54 by a pair of clamping ends 513 extending from the opening 54 side.

[0091] When the operating knob 51 is slid from the top to the bottom, the clamping position P on the movable lever 53 moves downward in conjunction with the movement of the operating knob 51, and also moves to the left on the movable lever 53, that is, from the base end 53a side (P1) to the free end 53b side (P2).

[0092] By mounting switch body 52 at an angle in this manner, it is possible to provide a drip-proof function using an existing switch body 52 without changing the shape of movable lever 53 of switch body 52. ​​More specifically, by mounting switch body 52 at an angle, movable lever 53 can be arranged so that it is inclined upward as a whole from free end 53b toward base end 53a.

[0093] Since the movable lever 53 is formed to be inclined upward, even if the disinfectant or the like that has entered through the opening 54 flows downward due to gravity or flows down the operation knob 51, etc., it can be prevented from adhering to the switch body 52 along the movable lever 53. This makes it possible to prevent damage to the switch body 52, etc., by the disinfectant or the like.

[0094] 〔summary〕 The slide switch structure according to aspect 1 of the present invention comprises a groove portion that penetrates the surface of a housing, an operation knob that is movably attached along the groove portion, and a slide switch that is arranged inside the housing, the slide switch comprising a switch body and a movable lever that are arranged in a position that does not overlap with the groove portion, and the movable lever is engaged with the operation knob inside the housing so as to move in conjunction with the operation knob.

[0095] According to the above configuration, the slide switch 5 is positioned so as not to overlap with the opening 54, so that even if dust, disinfectant, etc. enters through the opening 54, they can be prevented from adhering to the slide switch 5.

[0096] A slide switch structure according to a second aspect of the present invention is the slide switch structure of the first aspect, wherein the switch body is located above the groove portion.

[0097] According to the above configuration, the switch body 52 can be disposed above the opening 54, so that even if the disinfectant or the like that has entered through the opening 54 flows downward due to gravity or flows down along the operation knob 51 or the like, it can be prevented from adhering to the switch body 52. ​​This makes it possible to more reliably prevent damage to the switch body 52 or the like caused by the disinfectant or the like.

[0098] A slide switch structure according to aspect 3 of the present invention is the same as that of aspect 1 or 2 above, wherein the operating knob has a locking piece on the inside of the housing, and the movable lever is locked to the locking piece so as to form a predetermined angle with respect to the locking piece.

[0099] According to the above configuration, the slide switch 5 can be disposed at a position where it does not overlap with the opening 54.

[0100] A slide switch structure according to a fourth aspect of the present invention is the slide switch structure according to the third aspect, wherein the locking piece is a thin plate having a small thickness in the width direction of the groove.

[0101] According to the above configuration, by forming locking piece 512 in a thin plate shape, it is possible to reduce the width of opening 54 into which locking piece 512 is inserted. This makes it possible to prevent dust, disinfectant, etc. from entering the inside of housing 6 through opening 54. In addition, since it becomes difficult to see the inside of housing 6 through opening 54, it is possible to prevent the aesthetic appearance of communication device 10 from being impaired.

[0102] A slide switch structure according to a fifth aspect of the present invention is the slide switch structure of the third or fourth aspect, wherein the locking piece may include a pair of clamping ends that clamp the movable lever.

[0103] According to the above configuration, movable lever 53 is inserted between one clamping end and the other clamping end of a pair of clamping ends 513 and locked. In other words, movable lever 53 is not fixed to locking piece 512 by a fastening member such as a screw, and there is a slight clearance between movable lever 53 and locking piece 512. This allows the slide switch to operate without hindrance even if the vertical position or angle of movable lever 53 is slightly misaligned.

[0104] A slide switch structure according to aspect 6 of the present invention may be such that, in any of aspects 1 to 5 above, a protective sheet is attached to cover the groove portion from the inside of the housing, and the protective sheet has a slit through which the inserted operating knob can move along the groove portion.

[0105] According to the above configuration, protective sheet 81 has slit 811 through which operation knob 51 is inserted and which is movable along opening 54. Since the width of slit 811 is formed to be even smaller than the width of opening 54, it is possible to more reliably prevent the intrusion of disinfectant or the like through opening 54.

[0106] Furthermore, by attaching the protective sheet 81, the inside of the housing 6 becomes difficult to see through the opening 54, which further prevents the aesthetic appearance of the communication device 10 from being impaired.

[0107] A slide switch structure according to a seventh aspect of the present invention is the slide switch structure of the sixth aspect, wherein the protective sheet may be chemical resistant.

[0108] According to the above configuration, protective sheet 81 has chemical resistance and will not deform or discolor even when it comes into contact with a disinfectant, etc. Therefore, a disinfectant such as alcohol can be sprayed onto communication device 10 without damaging protective sheet 81.

[0109] An electric device (communications device 10) according to an eighth aspect of the present invention may include the slide switch structure according to any one of the first to seventh aspects.

[0110] The electric device according to a ninth aspect of the present invention is the electric device of the eighth aspect, and may further include a microphone or a speaker above the slide switch structure.

[0111] The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the claims. Embodiments obtained by appropriately combining the technical means disclosed in different embodiments are also included in the technical scope of the present invention. Furthermore, new technical features can be formed by combining the technical means disclosed in each embodiment. [Explanation of symbols]
