[0004] However, switches in which the optical element and the switch mechanism are assembled separately as described in Patent Document 1 have various problems due to assembly precision. The assembly precision is manifested as, for example, variations in the arrangement of optical elements such as light-emitting elements and light-receiving elements, variations in the arrangement of light-shielding plates, and variations in the arrangement of switch mechanisms such as housings. These variations in assembly precision cause problems such as variations in response time. Furthermore, in order to suppress the variations in response time, measures such as increasing the output of light emission are required, which causes problems such as increased power consumption.

[0011] The switch may further include a light receiving member that receives light emitted from the light emitting member, and a light receiving holder that holds the light receiving member.

[0012] In the switch, the light emitting member is assembled by being inserted into the light emitting holder in the optical axis direction.

[0013] In the switch, the light emitting member is assembled by being inserted into the light emitting holder from the outer bottom surface side perpendicular to the optical axis direction or from the side opposite the outer bottom surface.

[0014] Furthermore, the switch assembly disclosed in the present application comprises the switch and a substrate having a substantially flat mounting surface, the switch is mounted on the mounting surface of the substrate, and the light-emitting member provided on the switch is surface-mounted on the mounting surface of the substrate.

[0018] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0019] <Application Examples> The operating device disclosed in the present application is used, for example, as an operating device such as a mouse for operating a personal computer (hereinafter referred to as a PC). The switch disclosed in the present application is incorporated as a microswitch into various electronic devices and other devices including the operating device. The switch is incorporated into the operating device as a switch assembly (hereinafter referred to as a switch assembly) mounted on a board. Below, the operating device 1 and switch 2 illustrated in the drawings will be described with reference to the drawings, and further, a switch assembly 4 in which the switch 2 is mounted on a board 3 will be described.

[0020] <Control device 1> First, the operation device 1 will be described. FIG. 1 is a schematic perspective view showing an example of the appearance of the operation device 1 disclosed in the present application. FIG. 1 shows an example in which the operation device 1 disclosed in the present application is applied to a mouse used to operate an electronic device such as a personal computer. The operation device 1 includes a pressing operation unit 10 such as a mouse button that accepts a pressing operation by a user's finger, and a rotating operation unit 11 such as a mouse wheel that accepts a rotating operation by a user's finger. The rotating operation unit 11 is configured to accept not only a rotating operation but also a pressing operation, and also functions as the pressing operation unit 10. A signal line 12 that outputs an electric signal to an external device such as a personal computer is connected to the operation device 1. The operation device 1 can output an electric signal not only by wired communication using the signal line 12, but also by various communication methods such as wireless communication.

[0021] The operation device 1 accommodates a switch 2 (described later) inside as a switch assembly 4 for each of the pressing operation units 10 and the rotating operation unit 11. When an operator presses a pressing operation unit 10 in the operation device 1, the pressing operation unit 10 presses the corresponding switch 2 by an internal part (not shown). The switch 2 outputs a signal based on the pressing from a signal line 12 to an external electronic device such as a personal computer. In this way, the operation device 1 disclosed in the present application 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 the external electronic device via the signal line 12.

[0022] <Structure of switch assembly 4 and switch 2> Next, the switch assembly 4 and the switch 2 disclosed in the present application will be described. FIG. 2 is a schematic perspective view showing an example of the appearance of the switch assembly 4 disclosed in the present application. In the present specification, the directions of the switch 2 are expressed as follows: the left front side as viewed in FIG. 2 is the front, the right rear side is the rear, the left rear side is the left, the right front side is the right, the upper side is the top, and the lower side is the bottom; however, these directions are for convenience of explanation and do not limit the assembled direction of the switch 2. As described above, the switch assembly 4 is housed inside an electronic device such as the operating device 1, and accepts a pressing operation received by a portion such as a pressing operation unit 10 of the operating device 1 as a pressing pressure from the outside.

[0023] The switch assembly 4 is configured by attaching a switch 2, such as a microswitch, to a resin substrate 3 on which various circuits, elements, and wiring are formed.

[0024] The switch 2 includes a housing 20 having a substantially rectangular parallelepiped shape. A rectangular insertion hole 200, through which a pressing member 21 is inserted, is formed on the top surface of the housing 20 at a position toward the left of the center when viewed from the front. The pressing member 21 inserted into the insertion hole 200 is a member that receives pressure from outside the housing 20 and moves up and down within a range from an upper limit position to a lower limit position of its movement range. The upper end of the pressing member 21 protrudes from the top surface of the housing 20.

[0025] In the switch 2 thus formed, a pressing operation by an operator received by the pressing operation unit 10 of the operating device 1 is transmitted to the pressing member 21 as a pressing force from outside the housing 20. The pressing member 21 moves from an upper limit position to a lower limit position when pressed from the outside, and moves from the lower limit position to the upper limit position when the pressing force from the outside is released.

[0026] Next, the internal structures of the switch assembly 4 and the switch 2 will be described. FIG. 3 is a schematic exploded perspective view showing an example of the switch assembly 4 disclosed in the present application. FIG. 4 is a schematic perspective view showing an example of the switch 2 disclosed in the present application. FIG. 5 is a schematic cross-sectional view showing an example of the switch 2 disclosed in the present application. FIG. 4 shows the inside of the switch 2 disclosed in the present application from a perspective diagonally below and to the right, with the upper cover 20a of the housing 20 removed. FIG. 5 shows a cross section cut along a vertical plane passing through the line segment AB in FIG. 2, as viewed from the front.

[0027] The substrate 3 is formed in a generally rectangular flat plate shape, and has a generally flat mounting surface 30 on which the switch 2 is attached. The illustrated substrate 3 is illustrated with the mounting surface 30 as the upper surface. The substrate 3 is formed with a plurality of mounting holes 31 that penetrate vertically for fixing the attached switch 2. A thin plate electrode 32 is attached to the mounting surface 30 of the substrate 3 for surface mounting various elements.

[0028] The housing 20 of the switch 2 is in the shape of a substantially rectangular parallelepiped box, and its lower surface is an outer bottom surface 202 that abuts against the mounting surface 30 when the switch 2 is mounted on the board 3. The housing 20 is formed by an upper cover 20a and a lower base 20b. The upper cover 20a is a substantially rectangular parallelepiped box with an open lower surface, and the lower surface is closed by the base 20b. A space is provided within the housing 20 of the switch 2 as an accommodation chamber 203 that accommodates various members required for opening and closing an electric circuit. In addition to the pressing member 21 described above, the housing 20 accommodates various members such as a support member 22, a movable member 23, and an optical member 24 within the accommodation chamber 203. The housing 20 accommodates a light emitting member 24a and a light receiving member 24b as the optical member 24. An insertion hole 200 is formed in the upper surface of the cover 20a, which serves as the ceiling of the accommodation chamber 203, and the pressing member 21 is inserted into the insertion hole 200.

[0029] The base 20b of the housing 20 has a fixing portion 201 for fixing the support member 22 formed on an inner bottom surface located in the accommodation chamber 203. The lower surface of the base 20b is an outer bottom surface 202 of the housing 20 having a substantially rectangular parallelepiped shape, and when the switch 2 is attached to the mounting surface 30 of the board 3, the outer bottom surface 202 of the housing 20 is fixed in a state of abutting against the mounting surface 30 of the board 3. The housing 20 has a boss portion 204 protruding downward from the outer bottom surface 202, a pair of locking portions 205, and a pair of holding portions 206 formed on the lower part of the base 20b. When the switch 2 is attached to the board 3, the boss portion 204, the pair of locking portions 205, and the pair of holding portions 206 formed on the base 20b of the housing 20 are inserted into the mounting holes 31 of the board 3, respectively. The boss portion 204 is generally cylindrical with its central axis extending in the vertical direction, and is formed so as to protrude downward from a position on the outer bottom surface 202 toward the left from the center. The boss portion 204 is inserted into a generally circular mounting hole 31 formed in the substrate 3, and is used to determine the mounting position of the switch 2. The pair of locking portions 205 are formed so as to extend downward from the left and right positions sandwiching the boss portion 204 on the outer bottom surface 202, respectively, and have a snap-fit ​​structure in which the lower ends of each are bent toward the boss portion 204. The pair of locking portions 205 are inserted into the mounting hole 31 of the substrate 3, and are used to fix the switch 2 by the snap-fit ​​structure. The pair of holding portions 206 are portions that hold the optical members 24 formed in a row in front of and behind near the right end of the substrate 3. The pair of holding parts 206 are formed in a shape that partially protrudes downward from the mounting surface 30 so that a contact surface 240, which is the lower surface of the optical member 24, is flush with the outer bottom surface 202 of the switch 2 and comes into contact with the mounting surface 30 of the substrate 3, in order to surface-mount the optical member 24 on the thin plate electrode 32 of the mounting surface 30 of the substrate 3. The housing 20 is formed with a pair of holding parts 206, namely, a light-emitting holding part 206a that holds the light-emitting member 24a of the optical member 24 and a light-receiving holding part 206b that holds the light-receiving member 24b of the optical member 24, at the front and rear, and a gap is provided between the light-emitting holding part 206a and the light-receiving holding part 206b in which the movable member 23 is located.

[0030] The shape of the holding portion 206 formed on the housing 20 and the optical member 24 will be described in further detail. FIG. 6 is a schematic perspective view showing an enlarged portion of the switch 2 disclosed in the present application. FIG. 7 is a schematic cross-sectional view showing an enlarged portion of the switch 2 disclosed in the present application. FIGS. 6 and 7 show an enlarged view of the holding portion 206 formed on the housing 20, the optical member 24 held by the holding portion 206, and the vicinity thereof. FIG. 7 shows a cross section of the switch 2 attached to the board 3. The holding portion 206 of the housing 20 may be formed to hold the optical member 24 with some play, not necessarily in a completely fixed state, but preferably holds the optical member 24 so as to suppress movement in directions (up and down, left and right directions in FIG. 5) other than the optical axis direction (front and back directions in FIG. 5). The switch 2 disclosed in the present application can maintain accuracy and responsiveness even in a state in which the output related to the light emission and light reception of the optical member 24 is suppressed by stabilizing the position in the optical axis direction. The optical axis direction in this application indicates the direction in which light is irradiated, and indicates the so-called structural axis when implemented, but may be the direction of an axis defined by other definitions, such as the optical axis or the axis of maximum luminous intensity.

[0031] When assembling the switch 2, the optical member 24 (light emitting member 24a, light receiving member 24b) is assembled by inserting it into the holding portion 206 (light emitting holding portion 206a, light receiving holding portion 206b) in the optical axis direction. When the switch 2 is mounted on the board 3, the holding portion 206 of the housing 20 holds the optical member 24 so that the abutment surface 240 of the optical member 24 and the outer bottom surface 202 of the housing 20 abut against the mounting surface 30 of the board 3 in a substantially flush state. The optical member 24 of the switch 2, which is substantially rectangular and somewhat flat, has a concave electrode 241 with the left and right sides of the lower portion cut out to have a concave curved surface. When the optical member 24 is surface-mounted on the thin plate electrode 32 formed on the abutment surface 240 of the board 3, solder is applied to the concave electrode 241 of the optical member 24. Since solder is applied to the concave electrode 241 cut out into a concave curved shape, the optical member 24 can be surface mounted while maintaining the contact surface 240 in contact with the mounting surface 30 of the substrate 3.

[0032] 3, 4, and 5, various members accommodated in the accommodation chamber 203 of the housing 20 will be described. The support member 22 is a member that movably supports the movable member 23, and is fixed in the accommodation chamber 203 by a fixing part 201 of the housing 20. The support member 22 is a substantially U-shaped member that connects a first support part 220 standing on the left side in the accommodation chamber 203 and a second support part 221 standing in the approximate center in the accommodation chamber 203 by a connecting part 222 fixed to a lower part in the accommodation chamber 203 by the fixing part 201.

[0033] The movable member 23 is a member supported in the accommodation chamber 203 by the support member 22 and operates when pressed by the pressing member 21. The movable member 23 includes a movable piece 230 formed of a flexible thin metal plate and a shielding plate 231 that transmits / shields the light emitted from the light emitting member 24a. The movable piece 230 is arranged in the accommodation chamber 203 so that the longitudinal direction is the left-right direction. The left end side of the movable piece 230 is a fixed end supported by the first support part 220 of the support member 22, and serves as a swing fulcrum when the movable member 23 swings. The right end side of the movable piece 230 is a free end, to which the shielding plate 231 is attached. The movable piece 230 is punched out near the center in a tongue shape, and a biasing part 2300 that functions as an arc-shaped return spring is formed. The right end side of the biasing part 2300 is connected to the punched outer side, and the left end side is separated. The left end side of the biasing portion 2300 formed on the movable piece 230 is supported by the second support portion 221 of the support member 22. The movable piece 230 is supported by the support member 22 so that the biasing portion 2300 is deformed into an arc shape, so that the biasing portion 2300 functions as a leaf spring. The biasing portion 2300 generates a reaction force against the pressing force of the pressing member 21.

[0034] The shielding plate 231 of the movable member 23 has an upper portion that can be attached to the movable piece 230, and extends downward from the upper portion into a substantially rectangular plate shape. The shielding plate 231 is attached to the movable piece 230 at its upper portion so that the normal direction of the plate-like portion is the optical axis direction (front-rear direction) of the optical member 24. The shielding plate 231 is disposed so as to be located between the light emitting member 24a and the light receiving member 24b of the optical member 24. The shielding plate 231 has a substantially rectangular transmission window 2310 through which the light emitted from the optical member 24 passes.

[0035] The optical member 24 is a member held by the holder 206 in the accommodation chamber 203, and includes a light emitting member 24a held by the light emitting holder 206a and a light receiving member 24b held by the light receiving holder 206b. The optical member 24 is formed in a substantially flat shape, and the lower surface is substantially flat, forming a contact surface 240 that is surface mounted in a state of contact with the mounting surface 30 of the substrate 3. The light emitting member 24a emits light, and the light receiving member 24b receives the light emitted from the light emitting member 24a. The light emitting member 24a is configured using a light emitting element such as an LED (Light Emitting Diode), and the portion that emits light protrudes in the optical axis direction. The light receiving member 24b is configured using a light receiving element such as a PD (Photo Diode) or a PT (Photo Transistor) that detects light, and the portion that detects light protrudes in the optical axis direction. The light emitting member 24a and the light receiving member 24b are held by a light emitting holder 206a and a light receiving holder 206b, respectively, so that their optical axes coincide with each other, and are disposed on the substrate 3 facing each other.

[0036] <Switch 2 operation> Next, the opening and closing of the circuit in the switch 2 disclosed in the present application will be described. FIG. 8 and FIG. 9 are schematic cross-sectional views showing an example of the switch 2 disclosed in the present application. FIG. 8 shows a cross-section cut along a vertical plane passing through the line AB shown in FIG. 2 from a front view, and FIG. 9 shows a cross-section cut along a vertical plane passing through the line CD shown in FIG. 2 from a right view. FIG. 8 and FIG. 9 show a state in which the pressing member 21 is not subjected to pressure from the outside and is located at the upper limit position of the moving range. In the state in which the pressing member 21 is located at the upper limit position as illustrated in FIG. 8 and FIG. 9, the optical path between the light emitting member 24a and the light receiving member 24b is blocked by the shielding plate 231 of the movable member 23. Therefore, the light emitted from the light emitting member 24a is blocked by the shielding plate 231.

[0037] Fig. 10 is a schematic cross-sectional view showing an example of the switch 2 disclosed in the present application. Fig. 10 shows a state in which the pressing member 21 is pressed from the state shown in Fig. 8 and moves to the lower limit position of the moving range. In the state in which the pressing member 21 is located at the lower limit position shown in Fig. 10, the optical path between the light emitting member 24a and the light receiving member 24b passes through a transmission window 2310 formed in the shielding plate 231. Therefore, the light emitted from the light emitting member 24a is received by the light receiving member 24b.

[0038] In the switch 2 disclosed in the present application, the light receiving member 24b outputs a signal to an external electronic device to open or close a circuit according to the light receiving state of the light emitted from the light emitting member 24a by blocking / transmitting light based on a pressing operation. For example, when the pressing member 21 is in an open state at the upper limit position of its movement range, the light is blocked and the circuit is in an open state. On the other hand, when the pressing member 21 is in a pressed state at the lower limit position of its movement range, the light is transmitted and the circuit is in a closed state.

[0039] As described above, the switch 2 disclosed herein holds the optical members 24 (light emitting member 24a, light receiving member 24b) in the housing 20 by the holding portion 206 (light emitting holding portion 206a, light receiving holding portion 206b). The held optical members 24 are attached to the mounting surface 30 of the board 3 by surface mounting. Therefore, in the switch 2 disclosed herein, the optical members 24 are positioned by the holding portion 206, so that it is possible to prevent variations in arrangement during surface mounting and improve assembly accuracy. Therefore, the switch 2 disclosed herein can improve response time and accuracy without increasing the output for light emission, and thus has excellent effects such as being able to reduce power consumption.

[0040] <Other forms of Switch 2> FIG. 11 is a schematic exploded perspective view showing an example of the switch 2 disclosed in the present application. FIG. 11 shows another embodiment of the switch 2 disclosed in the present application. The switch 2 illustrated in FIG. 11 has a different embodiment in which the optical member 24 is assembled. The switch 2 includes a housing 20, a pressing member 21, a support member 22, a movable member 23, an optical member 24, and the like. The housing 20 is formed of a cover 20a and a base 20b. The base 20b is formed with a holding portion 206 with an open upper surface. The support member 22 has a bottom surface formed in a plate shape, and serves as a lid that covers the base 20b, such as the opening on the upper surface of the holding portion 206.

[0041] Fig. 12 is a schematic perspective view showing an enlarged portion of the switch 2 disclosed herein. Fig. 12 shows a state in which the optical member 24 is incorporated into the holding portion 206 formed on the base 20b of the housing 20. As illustrated in Fig. 12, the switch 2 disclosed herein is assembled by inserting the optical member 24 (light emitting member 24a, light receiving member 24b) into the holding portion 206 from above, that is, from the opposite side of the outer bottom surface perpendicular to the optical axis direction. After the optical member 24 is incorporated into the holding portion 206, the open upper surface of the holding portion 206 is closed by covering it with the support member 22.

[0042] <Other forms of Switch 2> FIG. 13 is a schematic perspective view showing an example of the switch 2 disclosed in the present application. FIG. 13 shows yet another embodiment of the switch 2 disclosed in the present application. The switch 2 shown in FIG. 13 has a different manner of assembling the optical member 24. FIG. 13 shows the switch 2 from an oblique downward angle, with one of the optical members 24 shown before attachment and the other shown after attachment. The holding portion 206 formed on the base 20b of the housing 20 of the switch 2 is open downward. The cover 20a of the housing 20 of the switch 2 is formed with a locking claw 207 that extends downward and has a bent tip. The locking claw 207 locks the optical member 24 held by the holding portion 206.

[0043] The switch 2 disclosed in the present application is assembled by inserting the optical members 24 (light emitting member 24a, light receiving member 24b) into the holding portion 206 (light emitting holding portion 206a, light receiving holding portion 206b) from below, i.e., from the outer bottom surface side perpendicular to the optical axis direction. The optical members 24 assembled into the holding portion 206 are locked by a locking claw 207.

[0044] The present invention is not limited to the above-described embodiments, and can be expanded into various other forms. Therefore, the above-described embodiments are merely illustrative in all respects and should not be interpreted as being restrictive. The technical scope of the present invention is described by the claims, and is not restricted in any way by the text of the specification. Furthermore, all modifications and changes within the equivalent scope of the claims are within the scope of the present invention.

[0045] For example, in the above embodiment, the holding portion 206 is shown to hold the light emitting member 24a so as to prevent movement in directions other than the optical axis direction, but the present invention is not limited to this and can be expanded into various forms, such as a holding form that prevents movement in the optical axis direction as well.

[0046] In addition, for example, in the above embodiment, the light emitting member 24a and the light receiving member 24b are disposed opposite each other, but the present invention is not limited to this. The switch 2 disclosed in the present application can be expanded into various forms, such as a reflective switch 2 in which the light emitting member 24a and the light receiving member 24b are provided on the same side of the shielding plate 231 and a reflector is provided at the opposing position.
