Switches and operating devices

Abstract

The present invention provides a switch and an operating device that can generate a click feeling. The switch (2) used for an operating device such as a mouse comprises: a movable part (26) that is flexible, with a first end side fixed as a swing fulcrum and a second end side swinging; and a pressing part (21) that receives pressure from the outside and presses between the first end and the second end of the movable part (26). A curved part (263) that bends along the swing direction is formed on the side of the movable part (26). When the movable part (26) is pressed by the pressing part (21) and deflects, the operator feels a click feeling because the curved part (263) resists the deflection of the movable part (26).

[0101] (Application example)

[0102] The operating device of the present invention is used as an operating device such as a mouse used to operate a personal computer (hereinafter referred to as a personal computer). In addition, the switch of the present invention is used as a micro switch of various electronic devices including the operating device. Hereinafter, the operating device 1 and the switch 2 shown in the drawings will be described with reference to the drawings.

[0103] (First Embodiment)

[0104] (Operating device 1)

[0105] First, the operating device 1 will be described. Figure 1 It is a schematic perspective view showing an example of the appearance of the operating device 1 according to the present invention. Figure 1The example in which the operating device 1 of the present invention is applied to a mouse for operating an electronic device such as a computer is shown. The operating device 1 includes a pressing operation portion 10 such as a mouse button for receiving an operation of pressing by an operator's finger, and a rotating operation portion 11 such as a mouse wheel for receiving an operation of rotating by an operator's finger. In addition, the rotating operation portion 11 is configured to receive not only a rotating operation but also a pressing operation, and also functions as the pressing operation portion 10. In addition, a signal line 12 for outputting an electrical signal to an external device such as a personal computer is connected to the operating device 1. In addition, the operating device 1 can output an electrical signal not only by wired communication using the signal line 12, but also by various communication methods such as wireless communication.

[0106] Inside the operating device 1, the push operation portion 10 and the rotation operation portion 11 each accommodate a switch 2 described later, and when the push operation portion 10 is pushed, the internal portion of the push operation portion 10 pushes the corresponding switch 2. The switch 2 outputs a signal based on the push condition from the signal line 12 to an external computer or other electronic device.

[0107] That is, the operating device 1 of the present invention includes a pressing operation unit 10 for receiving a pressing operation from the outside and a rotating operation unit 11 for receiving an operation such as a rotating operation, and further includes a switch 2 inside. Then, the operating device 1 transmits the pressing operation received by the pressing operation unit 10 and / or the rotating operation unit 11 to the switch 2 as a pressing from the outside, and outputs a signal based on the operation of the switch 2 to an external electronic device.

[0108] (Switch 2)

[0109] Next, the switch 2 according to the present invention will be described. Figure 2 2 is a schematic perspective view showing an example of the appearance of the switch 2 according to the present invention. Figure 2 The left front side is indicated as front, the right rear side is indicated as rear, the upper side is indicated as upper, and the lower side is indicated as lower, but this is for the convenience of explanation and does not limit the assembly direction of the switch 2. As described above, the switch 2 is housed inside an electronic device such as the operating device 1 as a micro switch, and receives a pressing operation received by a portion such as the pressing operation portion 10 of the operating device 1 as a pressing from the outside.

[0110] The switch 2 includes a housing 20 that is roughly in the shape of a rectangular parallelepiped. The housing 20 is formed of a base 20a at the bottom and a cover 20b at the top. On the top of the housing 20, a rectangular insertion hole 200 is provided at a position to the left of the center when viewed from the front, through which a pressing member 21 is inserted. The pressing member 21 inserted into the insertion hole 200 is a member that moves up and down by receiving pressure from the outside of the housing 20, and the upper end of the pressing member 21 protrudes from the upper surface of the housing 20. In addition, three connection terminal portions 22 protrude from the lower side of the housing 20, and the three connection terminal portions 22 are metal sheets that can be connected to other electrical components.

[0111] In the switch 2 thus formed, the external pressing operation received by the operating device 1 is transmitted to the pressing member 21 as a pressure from outside the housing 20. The pressing member 21 moves downward by receiving the external pressure, and moves upward when the external pressure is released.

[0112] Next, the internal structure of the switch 2 will be described. Figure 3 This is a schematic partially cutaway perspective view showing an example of the switch 2 according to the present invention. Figure 4 This is a schematic partially cutaway front view showing an example of the switch 2 according to the present invention. Figure 3 It shows that the front of the upper part of switch 2 is cut away and the interior is visible. Figure 4 Shown from the front viewpoint Figure 3 Switch 2 shown.

[0113] A contact chamber area for accommodating a contact mechanism for opening and closing a circuit is secured in the housing 20 of the switch 2. An insertion hole 200 penetrating from the outside of the housing 20 is provided on the upper surface of the contact chamber, and a pressing member 21 is inserted into the insertion hole 200.

[0114] The contact mechanism housed in the contact chamber is described. In the contact chamber, as a contact mechanism, components such as a common contact terminal 23, a first contact terminal 24, a second contact terminal 25, and a movable member 26 are provided. The common contact terminal 23 is provided on the left side of the contact chamber and is electrically connected to the connection terminal portion 22 on the left side. The first contact terminal 24 is provided on the upper right side of the contact chamber and is electrically connected to the connection terminal portion 22 on the right side. The second contact terminal 25 is provided on the lower right side of the contact chamber and is electrically connected to the connection terminal portion 22 in the center.

[0115] The movable member 26 is a plate-shaped conductive metal member extending in the left-right direction in the contact chamber, and has flexibility to bend in response to the pressure of the pressing member 21. The left end (first end) side of the movable member 26 is a fixed end that is locked with the common contact terminal 23 and acts as a swing fulcrum 260. The right end (second end) side of the movable member 26 is a free end that moves between the first contact terminal 24 and the second contact terminal 25, and serves as a movable contact 261. The movable member 26 is formed with a force-applying portion 262, which is punched out in a tongue shape from the right end side to the center and bent into an arc shape, and acts as a return spring between the pressed part that receives the pressure of the pressing member 21 and the right end. The front end of the force-applying portion 262 is locked by a locking plate 27 formed near the center of the contact chamber, and acts as a return spring to generate a reaction force against the pressure of the pressing member 21. A bent portion 263 bent downward in the swinging direction is formed on the side of the movable member 26. The bent portion 263 is formed by bending downward protruding pieces extending in a rectangular shape from both sides (front and rear directions in the figure) of the opposite side of the movable member 26.

[0116] In the contact mechanism thus constructed, the pressing member 21 receives external pressure and moves downward, pressing the movable member 26. By pressing the movable member 26, the right end side, which is the free end of the movable member 26, descends, and the movable contact 261 contacts the second contact terminal 25. As a result, the connection terminal portion 22 connected to the left side of the common contact terminal 23 and the connection terminal portion 22 connected to the center of the second contact terminal 25 are brought into conduction.

[0117] When the pressing of the pressing member 21 is released, the movable member 26 is urged upward by the reaction force of the force applying portion 262. The pressing member 21 moves upward by the force applied upward by the movable member 26. In addition, the movable member 26 is urged upward by the force applying portion 262, so that the movable contact 261 located at the right end side of the movable member 26 rises and contacts the first contact terminal 24. As a result, the connection terminal portion 22 connected to the left side of the common contact terminal 23 and the connection terminal portion 22 connected to the right side of the first contact terminal 24 are in a conductive state.

[0118] The shapes of the pressing member 21 and the movable member 26 will be further described. Figure 5A and 5B 1 is a schematic external view showing an example of the pressing member 21 included in the switch 2 according to the present invention. Figure 5A This is a schematic front view. Figure 5BIt is a schematic stereoscopic view shown from an oblique downward viewpoint. The pressing component 21 is composed of a pressed protrusion 210 on the upper side and a pressing plate 211 on the lower side. The pressed protrusion 210 of the pressing component 21 is roughly rectangular, and the upper end is formed as a semicircular curved surface when viewed from the front. The upper part of the pressed protrusion 210 protrudes from the insertion hole 200 of the housing 20 to receive pressure from the outside. The pressing plate 211 is formed into a roughly rectangular shape when viewed from above, and the lower surface opposite to the movable component 26 is formed into a roughly flat shape. The left end of the lower side of the pressing plate 211 is formed into a cone shape and tilted upward, and the first ridgeline 211a, which is the boundary between the flat part and the tapered part, extends in a straight line from front to back. In the second ridgeline 211b on the right end side of the lower side of the pressing plate 211, the part that contacts the movable component 26 is the part where the front and rear ends slightly protrude to the right. In the process of pressing the movable member 26 , the pressing member 21 comes into contact with the movable member 26 at least at a plurality of locations including the first ridgeline 211 a and the second ridgeline 211 b .

[0119] Fig. 6A and Figure 6B This is a schematic external view showing an example of the movable member 26 included in the switch 2 according to the present invention. Fig. 6A This is a rough floor plan. Figure 6B It is a schematic stereogram shown from a downward oblique viewpoint. The movable member 26 is a flexible member formed of a thin metal plate. The movable member 26 is roughly rectangular in plan view, and the right end side, which becomes the free end, is formed as a movable contact 261, and a contact protrusion 261a is protrudingly provided on the lower surface side of the movable contact 261. The above-mentioned force-applying portion 262 is formed from the left side of the movable contact 261 to the vicinity of the center. The force-applying portion 262 is formed in a manner that the portion punched out in a strip-like manner extending from the right side to the left side acts as a return spring, and the lower part is bent into a convex arc shape. The front end of the force-applying portion 262 is a stopper 262a, and the stopper 262a is stopped on the stopper plate 27 protruding from the base 20a of the housing 20. The force-applying portion 262 makes the stopper 262a stopped with the stopper plate 27 as a swing axis and becomes the side of the movable contact 261 on the right side. In addition, an opening punched out in a roughly rectangular shape is formed from the left end side to the vicinity of the center. The vicinity of the center between the right opening and the left opening where the force-applying portion 262 is formed becomes a pressed portion that receives pressure from the pressing member 21. In the movable member 26, a curved portion 263 that bends downward in the swinging direction is formed on the side near the left opening. The curved portion 263 is formed by bending downward protruding pieces extending in a rectangular shape from both sides of the opposite side of the movable member 26. The curved portion 263 is formed in the movable member 26 between the pressed portion that receives pressure from the pressing member 21 and the left end, so that the left end side of the movable member 26 is not easily bent relative to the pressure from the pressing member 21, and a tactile feeling of resistance to pressure is generated.

[0120] (Action of switch 2)

[0121] The operation of the switch 2 according to the present invention having the above configuration will be described. Figure 7 to Figure 10 This is a schematic cross-sectional view showing an example of the operation of the switch 2 according to the present invention. Figures 7 to 10 Shown from the front viewpoint in the Figure 2 The cross section is cut by a plane perpendicular to the line segment AB shown.

[0122] Figure 7 Indicates a state where the pressing member 21 is not pressed from the outside. The lower end of the pressing member 21 contacts the movable member 26 at the lower surface of the lower pressing plate 211, between the swing fulcrum 260 where the lower end of the movable member 26 is locked and the locking portion 262a at the front end of the force-applying portion 262 of the movable member 26 is locked. Figure 7 In the state shown, the movable part 26 is pushed upward by the force-applying portion 262 located between the pressed portion that receives the pressure of the pressing part 21 and the movable contact 261 to resist the reaction force of the pressing of the pressing part 21, so that the free end side formed as the movable contact 261 contacts the first contact terminal 24 arranged on the upper right side of the contact chamber.

[0123] Figure 8 Indicates from Figure 7 In the state shown, the pressing member 21 is in a state of moving downward under pressure from the outside. As the pressing member 21 moves downward, the pressing plate 211 located at the lower part of the pressing member 21 presses the movable member 26 downward. The pressing member 21 contacts the movable member 26 at two points, the first ridgeline 211a and the second ridgeline 211b of the pressing plate 211, relative to the movable member 26. The movable member 26 is pressed by the pressing member 21 as a whole, and moves downward with the swing fulcrum 260 as the swing axis. However, since the movable member 26 is pushed upward by the reaction force resisting the pressure of the pressing member 21 through the force applying portion 262 located between the pressed part receiving the pressure of the pressing member 21 and the movable contact 261, the movable contact 261 maintains the state of contacting the first contact terminal 24 arranged on the upper right side in the contact chamber. Therefore, the movable member 26 is pressed by the pressing member 21, bends downward, and becomes a flexed state.

[0124] Fig. 9 Indicates from Figure 8In the state shown, the pressing member 21 is further pressed from the outside and moves downward. As the pressing member 21 moves further downward, the movable member 26 is pressed by the pressing member 21 as a whole, and moves downward with the swing fulcrum 260 as the swing axis. In addition, the force-applying portion 262 of the movable member 26 swings downward with the locking portion 262a locked with the locking plate 27 as the swing axis, so that the movable member 26 swings as a whole in a reverse manner with the swing fulcrum 260 as the swing axis. Therefore, the contact protrusion 261a of the movable contact 261 contacts the second contact terminal 25 provided as a fixed contact on the lower right side of the contact chamber. As a result, the connection terminal portion 22 connected to the left side of the common contact terminal 23 and the connection terminal portion 22 connected to the center of the second contact terminal 25 are in a conductive state.

[0125] Fig.10 Indicates from Fig. 9 The state shown in the figure is changed to the state where the pressing member 21 receives further pressure from the outside and moves to the lowest point of the movable area. By moving the pressing member 21 to the lowest point, the entire movable member 26 is pressed by the pressing member 21, and the swing fulcrum 260 is moved downward as the swing axis. Therefore, the movable member 26 is supported by the swing fulcrums 260 and the movable contact 261 at both ends and bends downward. However, the conduction state does not change.

[0126] When the pressing of the pressing member 21 is released, the movable member 26 is urged upward by the reaction force of the force applying portion 262. The pressing member 21 moves upward by the force applying portion 262. In addition, the movable member 26 is urged upward by the force applying portion 262, so that the movable contact 261, which is the free end of the movable member 26, rises and contacts the first contact terminal 24. That is, Figure 7 Status shown.

[0127] like Figure 7 to Figure 10 As described in the example, the movable member 26 is swung while being bent by the pressing member 21. Since the bending portion 263 resists the force of the bending of the movable member 26, a large force generated by the bending portion 263 acts in the process of the movable member 26 bending and in the process of opening and reversing from bending. The force generated by the bending portion 263 resisting the bending is transmitted to the operator as a tactile sense of resistance to the pressing, and the operator feels a strong click.

[0128] Next, the noise reduction effect based on the shape of the pressing member 21 included in the switch 2 according to the present invention will be described. Fig.11A This is an explanatory diagram schematically showing an example of a dynamic system model related to the pressing member 21 and the movable member 26 included in the switch 2 according to the present invention. Fig. 11B1 is an explanatory diagram schematically showing an example of a dynamic system model related to a pressing member 21 x and a movable member 26 x included in a conventional switch 2 x. Fig.11A The pressing member 21 and the movable member 26 are shown from the front viewpoint. Fig. 11B For comparison, the conventional switch 2x is shown from the same viewpoint. Fig.11A and Fig. 11B In FIG. 1 , the dashed line indicates the center of the force that presses the movable members 26 and 26 x by receiving the pressure from the outside, and the arrow indicates the force that the pressing members 21 and 21 x apply to the movable members 26 and 26 x.

[0129] like Fig.11A As illustrated, the lower surface of the pressing plate 211 formed at the lower part of the pressing member 21 of the switch 2 described in the present invention is formed into a roughly flat shape. Since the movable member 26 is pressed by the pressing member 21 and flexes and bends downward, the pressing member 21 contacts the movable member 26 at two contact locations of the first ridge 211a and the second ridge 211b. That is, the pressing member 21 has, with respect to the center of the force for pressing the movable member 26 by receiving pressure from the outside, a first ridge 211a side that becomes a swing fulcrum 260 side and a second ridge 211b side that becomes a movable contact 261 side as contact locations. Furthermore, as indicated by the arrows in the figure, the pressing member 21 presses the movable member 26 at the two contact locations. In addition, at Fig. 11B In the conventional switch 2x shown for comparison, the lower portion of the pressing component 21x is formed into a downwardly convex arc shape, and the pressing component 21x contacts the movable component 26x at a contact point that is roughly consistent with the center of the pressing force. As shown by the arrow in the figure, the movable component 26x is pressed at the contact point.

[0130] Fig.12 It is an explanatory diagram schematically showing an example of a mechanical system model of a conventional switch 2x. Fig.13A and Fig. 13B This is an explanatory diagram schematically showing the relationship between the load and the movable member 26 x as a dynamic system model. Fig.14 2 is a graph schematically showing the relationship between the pressing amount and the operation load of the conventional switch 2 x as a dynamic model. Fig.12 The switch 2x is shown in a cross section cut along a vertical plane from a front viewpoint, and the movement of the movable member 26x is shown continuously. Fig.13A Schematic representation of the relationship between load and deflection of a beam supported at both ends. Fig. 13B Schematically represents the timing of the reversal action. Fig.14 The relationship is shown with the horizontal axis showing the pressing amount (operation stroke) of the pressing member 21 when the pressing member 21 x of the switch 2 x is pressed downward and the vertical axis showing the operation load received by the pressing member 21 x when pressed.

[0131] like Fig.12 As shown in FIG. 1 , the lower surface of the pressing member 21x is formed in an arc shape, so that during the pressing process, the pressing member 21x contacts the movable member 26x at one contact point. Fig.12 , Fig.13A and Fig. 13B The dashed white arrow indicates Fig.12 The pressing force when the pressing member 21x contacts the movable member 26x is shown in the position A. Fig.14 The dotted line indicates Fig.12 The relationship between the pressing amount and the operation load when the pressing member 21x and the movable member 26x come into contact at the position A shown. Fig.12 , Fig.13A and Fig. 13B The solid white arrows and Fig.14 The solid line shown indicates the relationship between the pressing force and the contact between the pressing member 21x and the movable member 26x at a position B closer to the swing fulcrum 260x side than the position A (toward the left side in the figure). Fig.12 , Fig.13A and Fig. 13B The dashed white arrows and Fig.14 The dashed line shown indicates the relationship between the pressing force and the movable member 26x when the pressing member 21x is assumed to be in contact with the movable member 26x at a position C closer to the movable contact 261x than the position A (toward the right side in the figure).

[0132] Fig.13A The relationship between the pressing force of the movable part 26x and the movable part 26x is shown assuming a beam supported at both ends. When assuming a beam supported at both ends, the force required to produce the same deflection is the largest at position B close to the swing fulcrum 260x, and then decreases in the order of position A and position C. Fig. 13B The timing of the reversal action is shown, where the position B close to the swing fulcrum 260x is the slowest, and then it becomes faster in the order of position A and position C. From these relationships, it is obtained Fig.14 The diagram shown. Fig.14 The point where the operating load drops sharply becomes the position where the movable member 26x reverses. Fig.14 As shown, at the reverse position, the load increases in the order of approaching the swing fulcrum 260x, and the time of the reverse action relative to the pressing amount becomes slower. Then, during the reverse action, a loud sound is generated.

[0133] Fig.15 2 is an explanatory diagram schematically showing an example of a mechanical system model of the switch 2 according to the present invention. Fig.15 For comparison, the white arrows shown by dashed, solid and dotted lines respectively indicate the Fig.12The pressing force when the positions corresponding to the positions A, B and C shown in FIG. 1 contact the movable member 26. Fig.15 As shown in FIG. 1 , the lower surface of the pressing member 21 of the switch 2 of the present invention is formed in a flat shape, so that during the pressing process, the pressing member 21 contacts the movable member 26 through two contact points. Fig.15 In the embodiment, the pressing member 21 of the switch 2 according to the present invention contacts the movable member 26 via both the first ridgeline 211 a (position B) and the second ridgeline 211 b (position C), thereby pressing the movable member 26 .

[0134] Fig.16A and Fig. 16B This is a graph schematically showing an example of the relationship between the pressing amount and the operation load as a dynamic system model. Fig.16A The graph showing the noise reduction effect caused by the pressing member 21 is compared. Fig.16A In FIG. 1 , a line D indicated by a thick line indicates the relationship between the pressing amount and the operation load of the switch 2 using the movable member 26 without the bent portion 263. Fig.16A For comparison, the dashed line A, the thin line B, and the dashed line C respectively represent the use of Fig.14 1 and 2 show the relationship between the pressing amount and the operation load at positions A, B, and C of the switch 2x where the pressing member 21x contacts the movable member 26x at one contact point without forming the bent portion 263 on the movable member 26x. Fig. 16B is a graph for comparing changes in the operating load caused by the influence of the curved portion 263. Fig. 16B In FIG. 1 , a line E indicated by a thin line is a switch 2 according to the present invention using a movable member 26 having a curved portion 263 and a pressing member 21 that contacts the movable member 26 at two contact locations. Fig. 16B In the figure, for comparison, thin lines and dotted lines represent a method of using movable parts 26 and 26x without forming a bending portion 263, line D represented by a thick line is a method of contacting the movable part 26 at two contact points, and line A represented by a dotted line is a method of contacting the movable part 26 at one contact point.

[0135] Fig. 16B The line A in the figure shows that the conventional pressing member 21 and the movable member 26 are used. When the pressing member 21 contacts the movable member 26 at the position A, the relationship between the pressing amount and the operation load changes sharply. Fig. 16BLine D in the figure is a method of using a pressing member 21 that contacts the movable member 26 at two locations, the first ridge 211a (position B) and the second ridge 211b (position C). The operation load changes from the position approximately the same as line C to the position approximately the same as line B with respect to the rapid change in the pressing amount. Due to the continuous change, the change is slow compared to lines such as line A. That is, when the movable member 26 is reversed, the switching time from the state of contact with the first contact terminal 24 to the state of collision with the second contact terminal 25 becomes longer, and the speed at which the contact protrusion 261a of the movable contact 261 collides with the second contact terminal 25 becomes slower. By slowing down the collision speed of the movable contact 261, the impact at the time of collision is mitigated, and the sound generated by the collision of the contact protrusion 261a, the so-called click sound, can be reduced. In addition, since the overall change is slow, the click feeling is weakened. Fig. 16B Line E in the figure is a method of using a pressing member 21 that contacts the movable member 26 forming the curved portion 263 at two locations. Since the pressing member 21 contacts the movable member 26 at two locations, a sudden change can be suppressed, and a silent effect of reducing the click sound can be obtained. However, since the operation load relative to the pressing amount is large, a stronger click feeling can be obtained compared to the method of line D.

[0136] As described above, in the switch 2 according to the present invention, the pressing member 21 contacts the movable member 26 at multiple locations, thereby suppressing the generation of sound compared to the case where the pressing member 21 contacts the movable member 26 at only one location. In addition, since the switch 2 according to the present invention has the curved portion 263 formed on the movable member 26, the operator can feel a sufficient click feeling while achieving silence.

[0137] In addition, in the movable member 26 , the position where the bent portion 263 is formed can be appropriately selected. Fig.17 This is a schematic partially cutaway perspective view showing an example of the switch 2 according to the present invention. Fig.18 This is a schematic partially cutaway front view showing an example of the switch 2 according to the present invention. Fig.17 It shows a situation where the front of the upper part of the switch 2 is cut off and the inside can be seen. Fig.18 Shown from the front viewpoint Fig.17 Switch 2 shown. Fig.19A and Fig.19B 2 is a schematic external view showing an example of a movable member 26 included in the switch 2 according to the present invention. Fig.17 , Fig.18 as well as Fig.19A as well as Fig.19BIn the movable component 26 of the switch 2 shown in the figure, a bent portion 263 is formed on the side near the right opening where the force-applying portion 262 is formed, which is bent downward in the swinging direction. The bent portion 263 is formed by bending downward protruding pieces extending upward in a rectangle from both sides of the opposite side of the movable component 26. The bent portion 263 is formed in the movable component 26 between the pressed portion that receives the pressure of the pressing component 21 and the right end, so that the right end side of the movable component 26 is not easily bent with respect to the pressure from the pressing component 21, and a tactile feeling of resistance to the pressure is generated. Fig.17 , 18 as well as Fig.19A and Fig.19B As shown, the formation position of the bent portion 263 can be appropriately designed.

[0138] (Second Embodiment)

[0139] The second embodiment is a method of suppressing the generation of sound by using a buffer component in the first embodiment to improve the quietness. In the following description, the same symbols as those of the first embodiment are assigned to the same structures as those of the first embodiment, and the first embodiment is referred to, and the description thereof is omitted. The appearance of the operating device 1 and the switch 2 using the second embodiment 2 is the same as that of the first embodiment, so the description thereof is omitted.

[0140] The internal structure of the switch 2 according to the second embodiment will be described. Fig. 20 This is a schematic exploded perspective view showing an example of the switch 2 of the present invention. Fig.21 This is a schematic cross-sectional view showing an example of a cross section of the switch 2 according to the present invention.

[0141] A region serving as a contact chamber is secured in the housing 20 of the switch 2. An insertion hole 200 penetrating from the outside of the housing 20 is provided on the upper surface of the contact chamber, and a pressing member 21 is inserted into the insertion hole 200.

[0142] In the contact chamber, components such as the common contact terminal 23, the first contact terminal 24, the second contact terminal 25, and the movable member 26 are arranged as a contact mechanism.

[0143] The movable member 26 is a conductive metal member having flexibility with respect to the pressing of the pressing member 21. The movable member 26 has a portion serving as a swing fulcrum 260 and a movable contact point 261, and is formed with a biasing portion 262 and a bending portion 263.

[0144] A contact buffer member 28 formed of an elastic material is disposed above the first contact terminal 24. The contact buffer member 28 is in contact with the first contact terminal 24 from above. In addition, a biasing portion buffer member 29 formed of an elastic material is disposed below the biasing portion 262 of the movable member 26. The biasing portion buffer member 29 is in contact with the biasing portion 262 from below.

[0145] In the contact mechanism thus constructed, the pressing member 21 receives external pressure and moves downward, pressing the movable member 26. By pressing the movable member 26, the right end side, which is the free end of the movable member 26, descends, and the movable contact 261 contacts the second contact terminal 25. As a result, the connection terminal portion 22 connected to the left side of the common contact terminal 23 and the connection terminal portion 22 connected to the center of the second contact terminal 25 are brought into conduction.

[0146] When the pressing of the pressing member 21 is released, the movable member 26 is urged upward by the reaction force of the force applying portion 262. The pressing member 21 moves upward by the force applying portion 262. In addition, the movable member 26 is urged upward by the force applying portion 262, so that the movable contact 261 located at the right end side of the movable member 26 rises and contacts the contact buffer member 28. In addition, when the movable contact 261 of the movable member 26 rises, the movable contact 261 may contact the first contact terminal 24 covered by the contact buffer member 28. In this case, the movable member 26 indirectly contacts the contact buffer member 28.

[0147] Fig.22A and Fig. 22B It is a schematic perspective view showing an example of a buffer member included in the switch 2 according to the present invention. Fig.22A Indicates the contact buffer component 28. The contact buffer component 28 is a component formed of an elastic material such as polyurethane rubber, and is formed by combining an upper component 280 and a lower component 281. The upper component 280 is roughly rectangular, and the right end side that is in contact with the inner wall surface of the housing 20 extends downward and is fixed. A cutout for the first contact terminal 24 to be engaged is formed in the fixed portion. On the lower surface of the left end side of the upper component 280, a lower component 281 that forms a roughly U-shaped shape when viewed from above is adhered. The contact buffer component 28 formed by the upper component 280 and the lower component 281 covers the first contact terminal 24, and the movable contact 261 that becomes the free end of the movable component 26 is directly or indirectly connected to the lower component 281 of the contact buffer component 28 via the first contact terminal 24.

[0148] Fig. 22B29 represents a buffer component 29 for the force-applying part. The buffer component 29 for the force-applying part is a component formed of an elastic material such as polyurethane rubber, and is formed in the shape of a platform 291 that is roughly rectangular on the lower surface of a plate-like body 290 that is roughly rectangular in plan view, and a cutout is formed on the inner side of the plate-like body 290 to fit with the second contact terminal 25. The upper surface of the plate-like body 290 at the left end side abuts against the lower surface of the force-applying part 262. Since the platform 291 is formed on the right side of the plate-like body 290, the left end side of the plate-like body 290 is subjected to the swing of the force-applying part 262, and is bent as shown by the arrow in the figure to absorb the impact.

[0149] (Action of switch 2)

[0150] The operation of the switch 2 according to the second embodiment of the present invention configured as described above will be described. Figure 23 to Figure 26 This is a schematic cross-sectional view showing an example of the operation of the switch 2 according to the present invention.

[0151] Fig.23 Indicates a state where the pressing member 21 is not pressed from the outside. The lower end of the pressing member 21 is in contact with the movable member 26 at the lower surface of the lower pressing plate 211 at a position between the swing fulcrum 260 where the left end of the movable member 26 is locked and the locking portion 262a at the front end of the force-applying portion 262 of the movable member 26 is locked. Fig.23 In the state shown, the movable part 26 is pushed upward by the force-applying portion 262 located between the pressed portion that receives the pressure of the pressing part 21 and the movable contact 261 to resist the reaction force of the pressing of the pressing part 21, so that the free end side formed as the movable contact 261 contacts the contact buffer part 28 arranged on the upper right side of the contact chamber.

[0152] Fig.24 Indicates from Fig.23 The state shown is a state where the pressing member 21 receives pressure from the outside and moves downward. As the pressing member 21 moves downward, the pressing plate 211 located below the pressing member 21 presses the movable member 26 downward.

[0153] Fig.25 Indicates from Fig.24 In the state shown, the pressing member 21 is further pressed from the outside and moves downward. As the pressing member 21 moves further downward, the movable member 26 is pressed by the pressing member 21 as a whole and moves downward with the swing fulcrum 260 as the swing axis. In addition, the force-applying portion 262 of the movable member 26 swings downward with the locking portion 262a locked to the locking plate 27 as the swing axis, so that the movable member 26 swings in a reverse manner as a whole with the swing fulcrum 260 as the swing axis.

[0154] The contact protrusion 261a of the movable contact 261 collides with the second contact terminal 25 with the kinetic energy of the reverse rotation of the movable member 26, and thus an impact is caused. However, since the left end side of the plate-like body 290 of the buffer member 29 with which the second contact terminal 25 is fitted is Fig. 22B Since the movable contact 261 of the movable member 26 is bent as shown by the arrow in the figure, the impact when the movable contact 261 of the movable member 26 collides with the second contact terminal 25 and the impact generated when the force applying portion 262 swings are absorbed. In addition, by alleviating the impact when the movable contact 261 of the movable member 26 collides with the second contact terminal 25, the sound generated by the collision can be suppressed. Although the impact generated by the collision of the movable contact 261 of the movable member 26 and the sound generated by the collision are suppressed, the bending portion 263 formed on both sides of the movable member 26 makes it difficult to bend the movable member 26, so the operation load increases. The force generated by the bending portion 263 resisting the bending is transmitted to the operator as a tactile sense of resisting pressing, and the operator feels a strong click feeling.

[0155] Fig.26 Indicates from Fig.25 The state shown in the figure is changed to the state where the pressing member 21 receives further pressure from the outside and moves to the lowest point of the movable area. As the pressing member 21 moves to the lowest point, the movable member 26 is pressed by the pressing member 21 as a whole and moves downward with the swing fulcrum 260 as the swing axis. Therefore, the movable member 26 is supported by the swing fulcrums 260 and the movable contact 261 at both ends and bends downward.

[0156] When the pressing of the pressing member 21 is released, the movable member 26 is urged upward by the reaction force of the force applying part 262. The pressing member 21 moves upward by the force applying part 26. In addition, the movable member 26 is urged upward by the force applying part 262, and the movable contact 261, which is the free end of the movable member 26, rises and contacts the contact buffer member 28. That is, Fig.23 When the pressing of the pressing member 21 is released and the movable member 26 rises, it collides with the contact buffer member 28. Since the impact caused by the collision is absorbed by the contact buffer member 28, the contact buffer member 28 mitigates the impact during the collision and suppresses the sound generated by the collision.

[0157] As described above, as described by way of example in the first and second embodiments, the switch 2 according to the present invention suppresses the sound generated by the movement of the movable member 26 by means of the shape of the pressing member 21 and the buffer members such as the contact buffer member 28 and the biasing member buffer member 29. Furthermore, in the switch 2 according to the present invention, since the curved portion 263 resists the deflection of the movable member 26, the operator can feel a strong click feeling while achieving silence, thereby achieving excellent effects.

[0158] The switch 2 illustrated in the first embodiment and the second embodiment can be extended to other various forms. Specifically, Fig.19A and Fig.19B As shown, the position and shape of the bent portion 263 of the movable member 26 can be appropriately designed as long as the shape is a shape that resists the deflection of the movable member 26 .

[0159] Other components included in the movable member 26 , for example, the shape of the pressing member 21 may be appropriately designed. Fig.27A and Fig.27B 1 is a schematic external view showing an example of the pressing member 21 included in the switch 2 according to the present invention. Fig.27A This is a schematic front view. Fig.27B This is a schematic stereogram from a downward oblique viewpoint. Fig.27A and Fig.27B In the illustrated pressing member 21 , portions corresponding to the first ridgeline 211 a and the second ridgeline 211 b protrude downward to form a first contact protrusion 212 c and a second contact protrusion 211 d . Fig.27A and Fig.27B The pressing member 21 shown in FIG. 1 abuts against the movable member 26 at the first contact portion 212c and the second contact portion 211d, and presses the movable member 26. Fig.27A and Fig.27B As shown, as long as the structure is such that the movable member 26 contacts at multiple locations only due to the difference in pressing, other modes for achieving the quiet effect can be developed.

[0160] (Third Embodiment)

[0161] The third embodiment is a method of applying the movable member 26 forming the curved portion 263 to a contactless switch using an optical element. In the following description, for the same structure as the first embodiment or the second embodiment, the same reference numerals as the first embodiment and the second embodiment are assigned, and the description thereof is omitted with reference to the first embodiment and the second embodiment. The appearance of the operating device 1 using the switch 2 of the third embodiment is the same as that of the first embodiment and the second embodiment, and therefore the description thereof is omitted.

[0162] The switch 2 according to the third embodiment will be described. Fig.28 The switch 2 is a schematic perspective view showing an example of the appearance of the switch 2 according to the present invention. The switch 2 is housed in an electronic device such as an operating device 1 as a micro switch and receives a pressing operation from the outside by a pressing operation portion 10 of the operating device 1 or the like.

[0163] The switch 2 includes a substantially rectangular parallelepiped housing 20. A connection terminal portion 22 and four optical contact terminals 30a protrude from the bottom of the housing 20. The connection terminal portion 22 fixes the switch 2 to an external component such as a substrate, and the optical contact terminals 30a are connected to the optical contacts 30 (see FIG. 1 ) described later and stored in the housing 20. Fig.29 The connection terminal portion 22 protrudes from the left end side of the lower side of the switch 2. The optical contact terminals 30a protrude from the right end side of the lower side of the switch 2 in a front-to-back and left-to-right arrangement. As the optical contact terminals 30a, there are protruding from the light emitting circuit 300 (see Fig.29 A pair of first optical contact terminals 300a extending rearwardly, and protruding from the light receiving circuit 301 (see Fig.29 A pair of second optical contact terminals 301a extending forward (etc.).

[0164] Next, the internal structure of the switch 2 will be described. Fig.29 1 is a schematic exploded perspective view showing an example of the switch 2 according to the present invention. Fig.30 This is a schematic cross-sectional view showing an example of a cross section of the switch 2 according to the present invention. Fig.30 is expressed from the front viewpoint in the Fig.28 The cross section is cut on a plane perpendicular to the CD line segment shown.

[0165] A contact chamber area for accommodating a contact mechanism for opening and closing a circuit is secured in a housing 20 of the switch 2. An insertion hole 200 penetrating from the outside of the housing 20 is provided on the upper surface of the contact chamber, and a pressing member 21 is inserted into the insertion hole 200.

[0166] The contact mechanism housed in the contact chamber is described. In the contact chamber, in addition to the above-mentioned optical contact 30, a first latching terminal 220, a second latching terminal 221, a movable component 26, and a fixed component 31 are provided as a contact mechanism. The optical contact 30 is arranged in front and back of the lower right side of the contact chamber as a light receiving circuit 301 and a light emitting circuit 300. The first latching terminal 220 is arranged on the lower left side of the contact chamber, and the second latching terminal 221 is arranged on the lower center side of the contact chamber. The first latching terminal 220 and the second latching terminal 221 are integrally formed with the connection terminal portion 22 below the housing 20. The fixed component 31 is arranged on the right side of the contact chamber between the light emitting circuit 300 and the light receiving circuit 301 of the optical contact 30. The movable component 26 is arranged in a manner extending left and right in the contact chamber, and is latched by the first latching terminal 220 and the second latching terminal 221.

[0167] The optical contact 30 includes a light emitting circuit 300 that emits light and a light receiving circuit 301 that receives light emitted from the light emitting circuit 300. The light emitting circuit 300 is formed using a light emitting element 300b such as an LED (Light Emitting Diode) and has a pair of first optical contact terminals 300a. The light receiving circuit 301 is formed using a light receiving element 301b such as a PD (Photo Diode) or a PT (Photo Transistor) and has a pair of second optical contact terminals 301a. The light emitting element 300b of the light emitting circuit 300 and the light receiving element 301b of the light receiving circuit 301 are arranged in a position facing each other so that the light receiving circuit 301 receives the light emitted from the light emitting circuit 300. When the light emitting circuit 300 is energized through the first optical contact terminal 300a, the light emitting element 300b of the light emitting circuit 300 emits light. When the light receiving element 301 b of the light receiving circuit 301 detects light, the current state changes. Therefore, an on signal based on the change in the current state of the received light is output from the second optical contact terminal 301 a .

[0168] The fixing member 31 is formed in the shape of a thin plate erected with the normal direction as the front-back direction, and is provided in a position in front of the light-emitting circuit 300 of the optical contact 30 and behind the light-receiving circuit 301, separated from the light-emitting circuit 300 and the light-receiving circuit 301. The lower part of the fixing member 31 is a light shielding plate 310 having a substantially circular through hole 311 through which light of the optical contact 30 passes, and the upper part is formed in a substantially U-shape bent like an arm and open on the left side. The fixing member 31 is configured so that the movable contact portion 264 on the right end side of the movable member 26 can be clamped from top to bottom at the upper U-shaped opening. The upper inner part of the opening of the fixing member 31 is a first contact portion 312 that contacts the movable contact portion 264 of the movable member 26 when the pressing member 21 is located above and the movable member 26 is not pressed by the pressing member 21. The lower inner part of the opening of the fixed member 31 is a second contact portion 313 that contacts the movable contact portion 264 of the movable member 26 when the pressing member 21 moves downward and presses the movable member 26. The movable contact portion 264 of the movable member 26 extends in a manner of entering between the first contact portion 312 and the second contact portion 313 of the fixed member 31. The front end of the first contact portion 312 of the fixed member 31 that extends to the left side protrudes downward so that the movable member 26 that is not pressed can easily hit it, and the movable member 26 contacts the first contact portion 312 from below. The central part of the second contact portion 313 of the fixed member 31 protrudes upward so that the movable member 26 that is pressed can easily hit it, and the movable member 26 contacts the second contact portion 313 from above. In order to produce an appropriate click sound, the fixed member 31 is preferably formed of a metal material, but it can also be formed of materials such as organic rubber, inorganic rubber, and hard resin. In addition, the fixing member 31 can be replaced as appropriate in order to make a click sound appropriate, for example.

[0169] The movable member 26 is a member made of metal such as SUS and formed in a plate shape extending in the left-right direction in the contact chamber. The left end side of the movable member 26 is a fixed end that is clamped with the first locking terminal 220 and functions as a swing fulcrum 260. The right end side of the movable member 26 is a movable contact portion 264 that moves as a free end between the first contact portion 312 and the second contact portion 313 of the fixed member 31. In addition, the right end side of the movable member 26 is a substantially rectangular light shielding sheet 266 that is bent downward from the movable contact portion 264. The light shielding sheet 266 is formed with the normal direction as the front-back direction, and has a substantially rectangular transmission window 265 through which the light of the optical contact 30 is transmitted. The light shielding sheet 266 is located in front of the fixed member 31, and enters between the fixed member 31 and the light receiving circuit 301 in a state where the position behind the light receiving circuit 301 of the optical contact 30 is separated from the fixed member 31 and the light receiving circuit 301. The movable member 26 is formed with a force-applying portion 262, which functions as a return spring punched out near the center and bent in an arc shape, and the front end of the force-applying portion 262 is locked with the second locking terminal 221 formed near the center of the contact chamber. The force-applying portion 262 generates a reaction force against the pressing of the pressing member 21. A bent portion 263 bent downward in the swinging direction is formed on the side of the movable member 26. The bent portion 263 is formed by bending downward protruding pieces extending in a rectangular shape from both sides of the opposite side of the movable member 26.

[0170] In the contact mechanism thus constructed, the pressing member 21 receives pressure from the outside and moves downward, pressing the movable member 26. By pressing the movable member 26, the movable contact portion 264 on the right end side of the free end of the movable member 26 descends, and the movable contact portion 264 contacts the second contact portion 313 of the fixed member 31. The movable contact portion 264 of the metal movable member 26 contacts the second contact portion 313 of the fixed member 31 in a manner of colliding, thereby generating a metallic sound. The user recognizes the metallic sound generated by the movable member 26 contacting the fixed member 31 as a click sound. When the movable member 26 is bent in response to the pressure from the pressing member 21, the curved portion 263 resists the bending of the movable member 26, and thus the operator feels a strong click feeling. In addition, by lowering the right end side of the movable part 26, the shading sheet 266 of the movable part 26 lowers, and the light of the optical contact 30 passes through the transmission window 265 opened on the shading sheet 266 of the movable part 26, thus becoming a connected state in which the circuit is closed, and a connection signal is output to the external electronic device.

[0171] When the pressing of the pressing member 21 is released, the movable member 26 is forced upward due to the reaction force of the force applying portion 262. The pressing member 21 moves upward due to the force applied to the movable member 26. In addition, the movable member 26 is forced upward by the force applying portion 262, so that the movable contact portion 264 located at the right end side of the movable member 26 rises, and the first contact portion 312 of the fixed member 31 abuts. In addition, as the right end side of the movable member 26 rises, the light shielding sheet 266 of the movable member 26 rises, and the light of the optical contact 30 is blocked by the light shielding sheet 266, and the circuit is opened to the disconnected state.

[0172] The opening and closing of the circuit of the optical contact 30 , the fixed member 31 , and the movable member 26 will be further described. Fig.31A and Fig.31B and Fig.32 This is a schematic cross-sectional view showing an example of a cross section of the switch 2 according to the present invention. Fig.31A and Fig.31B The image is enlarged from the upper right viewpoint and includes Fig.28 The cross section is cut on a plane perpendicular to line segment EF shown. Fig.32 Shown from the right viewpoint in the Fig.28 The cross section is cut on the vertical plane of the EF line segment shown. Fig.31A Indicates the off state where the pressing member 21 is located at the top and the pressing of the pressing member 21 is released and the circuit is opened. Fig.31B and Fig.32 This indicates an on-state in which the pressing member 21 moves downward and the pressing member 21 presses to close the circuit.

[0173] When the pressing of the pressing member 21 is released, Fig.31A As shown, the light shielding sheet 266 of the movable member 26 rises, and the transmission window 265 of the light shielding sheet 266 deviates from the optical path from the light emitting element 300b of the light emitting circuit 300 to the light receiving element 301b of the light receiving circuit 301. Therefore, the light emitted from the light emitting element 300b of the light emitting circuit 300 passes through the transmission hole 311 formed in the light shielding plate 310 of the fixed member 31, but is blocked by the light shielding sheet 266 of the movable member 26, and thus does not reach the light receiving element 301b of the light receiving circuit 301, and the circuit is turned into an open state.

[0174] When the pressing member 21 is pressed, Fig.31B and Fig.32 As shown, the light shielding sheet 266 of the movable member 26 is lowered, and the light path from the light emitting element 300b of the light emitting circuit 300 to the light receiving element 301b of the light receiving circuit 301 passes through the transmission window 265 opened on the light shielding sheet 266. Therefore, the light emitted from the light emitting element 300b of the light emitting circuit 300 is Fig.32As shown by the white arrow in the figure, the light passes through the through hole 311 opened on the shading plate 310 of the fixed part 31, and then through the through window 265 opened on the shading sheet 266 of the movable part 26, reaching the light receiving element 301b of the light receiving circuit 301, and the circuit is closed.

[0175] As described above, the switch 2 according to the present invention in the third embodiment forms the curved portion 263 and uses the movable member 26 having the light shielding sheet 266, thereby generating a click feeling and a click sound in accordance with the pressing operation of the mouse pressing operation portion 10. Thus, the user can recognize the completion of the click operation from the click feeling and the click sound, and an excellent effect is achieved.

[0176] The switch 2 of the present invention described as the third embodiment is not limited to the illustrated embodiment, and can be extended to other various forms. For example, the fixing member 31 used for the switch 2 is not limited to the shape illustrated as the third embodiment, and can be designed appropriately. Fig.33 It is a schematic front view showing an example of the appearance of the fixing member 31 included in the switch 2 according to the present invention. Fig.33 The lower left side of the fixing member 31 shown extends downward in the direction of the figure to form a connection terminal portion 22 that protrudes downward from the center of the lower surface of the housing 20 (protrudes in the pressing direction of the pressing member 21). By integrally forming the connection terminal portion 22 and the fixing member 31, the area of ​​the light shielding plate 310 of the fixing member 31 becomes larger, thereby improving the light shielding property, shielding various lights, suppressing the generation of noise, and improving the accuracy.

[0177] In addition, for example, the switch 2 of the present invention can be developed in a manner that removes the fixing member 31 from the third embodiment. By removing the fixing member 31, the generation of the click sound can be suppressed to achieve a silent effect, while also generating a click feeling, etc., achieving excellent effects.

[0178] (Fourth Embodiment)

[0179] The fourth embodiment is a method of mounting the optical contact 30 as a surface mounted chip in a contactless switch using the optical element shown in the third embodiment. In the following description, for the same structure as any one of the first to third embodiments, the first to third embodiments are referred to, and their description is omitted. Since the appearance of the operating device 1 using the switch 2 of the fourth embodiment is the same as that of the first to third embodiments, the description is omitted.

[0180] The switch 2 according to the fourth embodiment will be described. Fig.34The switch 2 is a schematic perspective view showing an example of the appearance of the switch 2 according to the present invention. The switch 2 is housed in an electronic device such as an operating device 1 as a micro switch and receives a pressing operation from the outside by a pressing operation portion 10 of the operating device 1 or the like.

[0181] The switch 2 includes a housing 20 that is substantially in the shape of a rectangular parallelepiped. A connection terminal portion 22 and four mounting optical contact terminals 32 protrude from the lower surface of the housing 20. The connection terminal portion 22 fixes the switch 2 to an external component such as a substrate, and the mounting optical contact terminals 32 are connected to the optical contacts 30 (see FIG. 1 ) described later and stored in the housing 20. Fig.35 The connection terminal portion 22 protrudes downward from the left end side of the bottom of the switch 2. As the mounting optical contact terminal 32, a third optical contact terminal 320, a fourth optical contact terminal 321, a fifth optical contact terminal 322, and a sixth optical contact terminal 323 are arranged in sequence from the center of the bottom of the switch 2 to the right end side.

[0182] Next, the internal structure of the switch 2 will be described. Fig.35 It is a schematic exploded perspective view showing an example of the switch 2 of the present invention. Fig.36 This is a schematic cross-sectional view showing an example of a cross section of the switch 2 according to the present invention. Fig.37 It is a schematic perspective view showing an example of the optical contact 30 and the mounting optical contact terminal 32 included in the switch 2 according to the present invention. Fig.36 Shown from the front viewpoint in the Fig.34 The cross section is cut on the vertical plane of the GH line segment shown. Fig.36 In FIG. 1 , a portion of the internal structure of the switch 2 surrounded by a dotted circle is shown enlarged. Fig.37 The optical contact 30 and the mounting optical contact terminal 32 are shown from a viewpoint obliquely viewed from the upper right front.

[0183] A contact chamber area for accommodating a contact mechanism for opening and closing a circuit is secured in a housing 20 of the switch 2. An insertion hole 200 penetrating from the outside of the housing 20 is provided on the upper surface of the contact chamber, and a pressing member 21 is inserted into the insertion hole 200.

[0184] The contact mechanism housed in the contact chamber is described. In the contact chamber of the housing 20, in addition to the above-mentioned optical contact 30, a first latching terminal 220, a second latching terminal 221, and a movable component 26 are housed as a contact mechanism. The optical contact 30 is arranged on the lower right side of the contact chamber as a light emitting circuit 300 and a light receiving circuit 301 along the left and right sides. The first latching terminal 220 is arranged on the lower left side of the contact chamber, and the second latching terminal 221 is arranged on the lower center side of the contact chamber. The first latching terminal 220, the second latching terminal 221, and the connecting terminal portion 22 below the housing 20 are integrally formed. The movable component 26 is arranged in a manner extending left and right along the inner edge of the contact chamber, and is latched by the first latching terminal 220 and the second latching terminal 221.

[0185] The optical contact 30 includes a light emitting circuit 300 and a light receiving circuit 301. The light emitting circuit 300 of the optical contact 30 is formed as a surface mounted chip using a light emitting element 300b. The light receiving circuit 301 of the optical contact 30 is formed as a surface mounted chip using a light receiving element 301b. The light emitting circuit 300 is in the shape of a flat rectangular parallelepiped, a part of the side protrudes in a flat semicircular shape, and the light emitting element 300b is assembled in the protruding portion. The light receiving circuit 301 is in the shape of a flat rectangular parallelepiped, a part of the side protrudes in a flat semicircular shape, and the light receiving element 301b is assembled in the protruding portion. The light emitting element 300b of the light emitting circuit 300 and the light receiving element 301b of the light receiving circuit 301 are arranged in a manner of facing each other so that the light receiving circuit 301 receives the light emitted from the light emitting circuit 300.

[0186] The light emitting circuit 300 of the optical contact 30 is surface mounted on the third optical contact terminal 320 and the fourth optical contact terminal 321 so as to cross between the third optical contact terminal 320 and the fourth optical contact terminal 321 arranged on the left side of the optical contact terminal 32 for mounting. The light receiving circuit 301 of the optical contact 30 is surface mounted on the fifth optical contact terminal 322 and the sixth optical contact terminal 323 so as to cross between the fifth optical contact terminal 322 and the sixth optical contact terminal 323 arranged on the right side of the optical contact terminal 32 for mounting.

[0187] Fig.38A and Fig.38B This is a schematic enlarged view showing a part of an example of the optical contact 30 and the mounting optical contact terminal 32 included in the switch 2 according to the present invention. Fig.38A 1 is a schematic perspective view showing in enlarged form the mounting position of the light receiving circuit 301 of the optical contact 30 mounted on the fifth optical contact terminal 322 and the sixth optical contact terminal 323. Fig.38B This is a schematic side view from the left side. Fig.38A and Fig.38BFor the convenience of drawing, the upper direction is shown as the left side of the figure. The fifth optical contact terminal 322 and the sixth optical contact terminal 323 are formed with a recess 32a for placing the light receiving circuit 301, and the light receiving circuit 301 is surface mounted in a state of being placed in the recess 32a of the fifth optical contact terminal 322 and the sixth optical contact terminal 323. The third optical contact terminal 320 and the fourth optical contact terminal 321 of the surface mounted light emitting circuit 300 are also similarly formed with a recess 32a for surface mounting in a state of placing the light emitting circuit 300. By forming the recess 32a on the mounting optical contact terminal 32, the optical contact 30 is placed on the recess 32a and surface mounted, thereby facilitating positioning during surface mounting, and making it possible to reduce the thickness of the mounting portion in the front-back direction.

[0188] Return to Fig.35 , Fig.36 and Fig.37 , further describing the mounting optical contact terminal 32. The upper portion of the sixth optical contact terminal 323 extends upward, bends toward the left in an arm shape, and protrudes to the vicinity of the upper portion of the third optical contact terminal 320 and the fourth optical contact terminal 321, and the protruding portion is bent forward to form a third abutting portion 323a abutted by the movable abutting portion 264 on the right end side of the movable member 26. The upper portion of the third optical contact terminal 320 protrudes upward, and the protruding portion is bent forward to form a fourth abutting portion 320a abutted by the movable abutting portion 264 of the movable member 26. The movable member 26 is configured so that the movable abutting portion 264 on the right end side enters between the third abutting portion 323a and the fourth abutting portion 320a. In addition, the movable member 26 abuts against the third abutting portion 323a from below when not pressed by the pressing member 21, and abuts against the fourth abutting portion 320a from above when pressed.

[0189] The light emitting circuit 300 is energized through the third optical contact terminal 320 and the fourth optical contact terminal 321, and the light emitting element 300b of the light emitting circuit 300 emits light. When the light receiving element 301b of the light receiving circuit 301 detects light, the energization state changes, and therefore, the fifth optical contact terminal 322 and the sixth optical contact terminal 323 output an on signal based on the change in the energization state of the light received.

[0190] The movable member 26 is a metal member such as SUS formed in a plate shape extending in the left-right direction in the contact chamber. The right end side of the movable member 26 is a movable contact portion 264 that moves as a free end between the third contact portion 323a and the fourth contact portion 320a, and further, a light shielding sheet 266 that bends downward from the movable contact portion 264. The light shielding sheet 266 is formed with the normal direction as the left-right direction, and has a substantially rectangular transmission window 265 through which light of the optical contact 30 is transmitted. The light shielding sheet 266 is located on the right side of the light emitting circuit 300 of the optical contact 30, and enters between the light emitting circuit 300 and the light receiving circuit 301 in a state where the position to the left of the light receiving circuit 301 of the optical contact 30 is separated from the light emitting circuit 300 and the light receiving circuit 301. In addition, a force-applying portion 262 is formed on the movable member 26. The force-applying portion 262 functions as a return spring that is punched out near the center and bent in an arc shape. The front end of the force-applying portion 262 is locked with the second locking terminal 221 formed near the center of the contact chamber. The force-applying portion 262 generates a reaction force against the pressing of the pressing member 21. A bent portion 263 that is bent downward in the swinging direction is formed on the side of the movable member 26. The bent portion 263 is formed by bending downward protruding pieces that extend in a rectangular shape from both sides of the opposite side of the movable member 26.

[0191] In the contact mechanism thus constructed, the pressing member 21 receives pressure from the outside and moves downward, pressing the movable member 26. By pressing the movable member 26, the movable contact portion 264 on the right end side of the free end of the movable member 26 descends, and the movable contact portion 264 contacts the fourth contact portion 320a of the third optical contact terminal 320. The movable contact portion 264 of the metal movable member 26 contacts the fourth contact portion 320a of the metal third optical contact terminal 320, thereby generating a metallic sound. The user recognizes the metallic sound generated by the contact between the movable member 26 and the mounting optical contact terminal 32 as a click sound. When the movable member 26 is bent in response to the pressure from the pressing member 21, the curved portion 263 resists the bending of the movable member 26, so that the operator feels a strong click feeling. In addition, by lowering the right end side of the movable part 26, the shading sheet 266 of the movable part 26 lowers, and the light of the optical contact 30 passes through the transmission window 265 opened on the shading sheet 266 of the movable part 26, thus becoming a connected state in which the circuit is closed, and a connection signal is output to the external electronic device.

[0192] When the pressing of the pressing member 21 is released, the movable member 26 is forced upward due to the reaction force of the force applying portion 262. The pressing member 21 moves upward due to the force applied to the movable member 26. In addition, the movable member 26 is forced upward by the force applying portion 262, so that the movable contact portion 264 located at the right end side of the movable member 26 rises and abuts against the third abutting portion 323a of the sixth optical contact terminal 323. In addition, as the right end side of the movable member 26 rises, the light shielding sheet 266 of the movable member 26 rises, and the light of the optical contact 30 is blocked by the light shielding sheet 266, and the circuit is opened to the disconnected state.

[0193] The opening and closing of the circuit of the optical contact 30 , the mounting optical contact terminal 32 , and the movable member 26 will be further described. Fig.39A and Fig.39B This is a schematic enlarged view showing a part of the internal structure of the switch 2 according to the present invention. Fig.39A and Fig.39B 2 is a schematic three-dimensional diagram showing the vicinity of the light shielding sheet 266 of the movable member 26 in an enlarged manner. Fig.39A The pressing member 21 is in the upper position, the pressing of the pressing member 21 is released, and the circuit is opened. Fig.39B This is an on state indicating that the pressing member 21 is located at the bottom and the pressing member 21 is pressing to close the circuit.

[0194] When the pressing of the pressing member 21 is released, Fig.39A As shown, the light shielding sheet 266 of the movable member 26 rises, and the transmission window 265 of the light shielding sheet 266 deviates from the optical path from the light emitting element 300b of the light emitting circuit 300 to the light receiving element 301b of the light receiving circuit 301. Therefore, the light emitted from the light emitting element 300b of the light emitting circuit 300 is blocked by the light shielding sheet 266 of the movable member 26, and therefore does not reach the light receiving element 301b of the light receiving circuit 301, and the circuit is in an open disconnected state.

[0195] When the pressing member 21 is pressed, Fig.39B As shown, the light shielding sheet 266 of the movable member 26 moves down, and the optical path from the light emitting element 300b of the light emitting circuit 300 to the light receiving element 301b of the light receiving circuit 301 passes through the transmission window 265 opened in the light shielding sheet 266. Therefore, the light emitted from the light emitting element 300b of the light emitting circuit 300 passes through the transmission window 265 opened in the light shielding sheet 266 of the movable member 26 and reaches the light receiving element 301b of the light receiving circuit 301, and the circuit is closed and the light is in the on state.

[0196] When manufacturing the switch 2 of the present invention having the above structure, for example, a conductive metal plate is punched out by stamping such as punching to form a mold of one connection terminal portion 22 and four mounting optical contact terminals 32. Furthermore, the punched-out molds of the connection terminal portion 22 and the mounting optical contact terminals 32 are subjected to stamping such as flange processing to form the connection terminal portion 22 and the mounting optical contact terminals 32. Then, the optical contact 30 is mounted on the upper surface of the mounting optical contact terminal 32, and the pressing member 21 and the movable member 26 are molded and housed in the housing 20 to form the switch 2. Then, the formed switch 2 is assembled to complete the operating device 1.

[0197] As described above, the switch 2 of the present invention mounts the optical contact 30 formed as a surface-mounted chip on the mounting optical contact terminal 32, so that the manufacturing process can be prevented from being complicated, and it can be expected that the cost can be reduced, etc., and excellent effects can be exerted. In addition, by mounting the switch 2 of the present invention as a surface-mounted chip, miniaturization can be easily achieved. In addition, in the case where the optical contact 30 is surface-mounted on the mounting optical contact terminal 32, the manufacturer of the switch 2 can manage the process from the formation of the optical contact 30 to the surface mounting, and even the formation of the switch 2 based on molding. Therefore, the manufacturer of the switch 2 can integrally manage the quality of the optical contact 30 as a sensor and the action mechanism, suppress the deviation of the action characteristics, and thus stabilize the quality. In addition, by suppressing the deviation of the action characteristics to achieve stabilization of the quality, it can be expected that the output speed will be increased.

[0198] Furthermore, since the switch 2 of the present invention according to the fourth embodiment is formed with the bent portion 263, a click feeling is generated in accordance with the pressing operation of the mouse pressing operation portion 10, and in accordance with the pressing operation, a metallic sound recognized as a click sound is generated by the contact between the metal movable member 26 and the metal mounting optical contact terminal 32. Thus, although it is a contactless switch, a click feeling and a click sound can be generated, and excellent effects are exerted.

[0199] The present invention is not limited to the various embodiments described above, and can be extended to various other modes. Therefore, the above embodiments are merely examples in all aspects and cannot be used to limit the interpretation of the present invention. The technical scope of the present invention is described by the claims and is not subject to any restrictions in the specification. Moreover, all deformations and changes belonging to the equivalent scope of the claims are within the scope of the present invention.

[0200] For example, the first to fourth embodiments do not need to be implemented separately. For example, in the switch 2 having the optical contact 30 shown in the third and fourth embodiments, the pressing member 21 shown in the first and second embodiments may be applied or appropriately combined.

[0201] For example, in the above embodiment, the bending portion 263 of the movable member 26 is bent downward in one direction of the swinging direction, but it may be bent upward in the other direction of the swinging direction as long as it is formed to resist bending of the movable member 26 .

[0202] In the above embodiment, a mouse is exemplified as the operating device 1 having the switch 2, but the present invention is not limited thereto, and various devices such as a keyboard and various buttons for operation may be applied as the operating device 1, and the present invention may be expanded to various forms.
