< application example >
The operation device described in the present application is used as an operation device such as a mouse for operating a personal computer (hereinafter referred to as a personal computer). The switch described in the present application is incorporated as a microswitch in various electronic devices including an operating device. The switch is incorporated in the operating device as a switch unit (hereinafter referred to as a switch assembly) mounted on the substrate. Next, with reference to the drawings, the operation device 1 and the switch 2 illustrated in the drawings, and further, the switch assembly 4 in which the switch 2 is attached to the base plate 3 will be described.
< operating device 1 >
First, the operation device 1 will be explained. Fig. 1 is a schematic perspective view showing an example of an external appearance of an operation device 1 described in the present application. Fig. 1 shows an example in which the operation device 1 described in the present application is applied to a mouse used for operating an electronic device such as a personal computer. The operation device 1 includes: a pressing operation part 10 such as a mouse button for receiving an operation of pressing by a user's finger, and a rotation operation part 11 such as a mouse wheel for receiving an operation of rotating by a user's finger. The rotation operation unit 11 is configured to receive not only the rotation operation but also the depressing operation, and also serves as the depressing operation unit 10. Further, a signal line 12 for outputting an electronic signal to an external device such as a personal computer is connected to the operation device 1. The operation device 1 is not limited to wired communication using the signal line 12, and may output an electronic signal by various communication methods such as wireless communication. Further, a light emitting portion 13 designed in a wave shape is formed at a side portion of the operation device 1. The light emitting unit 13 includes a translucent resin plate and a built-in output load unit 130 (see fig. 14 and the like). The output load section 130 included in the Light Emitting section 13 is formed using an LED (Light Emitting Diode). The LED incorporated as the output load section 130 emits light therein, and the light emitting section 13 emits light.
In addition to the output load unit 130, a switch 2 described later is housed in each of the pressing operation unit 10 and the rotation operation unit 11 in the operation device 1, and when the pressing operation unit 10 is pressed, the switch 2 corresponding to a portion in the pressing operation unit 10 is pressed. The switch 2 outputs a signal based on the pressing state from the signal line 12 to an electronic device such as an external personal computer.
That is, the operation device 1 described in the present application includes: a pressing operation part 10 for receiving pressing operation from outside, a rotation operation part 11 for receiving operation such as rotation operation, and a light emitting part 13, and a switch 2 and an output load part 130 are provided inside. The operation device 1 transmits the pressing operation received by the pressing operation unit 10 and/or the rotation operation unit 11 to the switch 2 as an external pressing operation, and outputs a signal based on the operation of the switch 2 from the signal line 12 to an external electronic device.
< Structure of switch 2 >
Next, the switch 2 described in the present application will be described. Fig. 2 is a schematic perspective view showing an example of an external appearance of the switch 2 described in the present application. In the present specification, the direction of the switch 2 is shown below with the front left side as the front and the depth right side as the rear, and the front left side as the front left side and the front right side as the upper right side and the lower upper side as the rear, with respect to fig. 2, and is a direction for convenience of explanation and is not intended to limit the assembly direction of the switch 2. As described above, the switch 2 is housed as a microswitch in an electronic device such as the operation device 1, and receives a pressing operation received from a portion such as the pressing operation portion 10 of the operation device 1 as a pressing operation from the outside.
The switch 2 has a housing 20 formed in a substantially rectangular parallelepiped shape. The enclosure 20 is formed of a lower base 20a and an upper lid 20 b. A rectangular insertion hole 200 through which the pressing member 21 is inserted is formed in the upper surface of the housing 20 at a position on the left side from the center in the front view. The pressing member 21 inserted into the insertion hole 200 is a member that receives a pressing force from the outside of the housing 20 and moves up and down in a range from a first position above to a second position below, and an upper end of the pressing member 21 protrudes from the upper surface of the housing 20.
Further, a first terminal 220 which is a part of a supporting member 22 (see fig. 3 and the like) described later, a second terminal 230 which is a part of a contacted member 23 (see fig. 3 and the like) described later, a third terminal pair 240 which is a part of a light emitting unit 24 (see fig. 3 and the like) described later, and a fourth terminal pair 250 which is a part of a light receiving unit 25 (see fig. 3 and the like) described later protrude from the lower surface of the enclosure 20. The first terminal 220 protrudes from the left end side of the lower surface of the housing 20. The second terminals 230 protrude from the vicinity of the center of the lower surface of the housing 20. The third terminal pair 240 and the fourth terminal pair 250 protrude from the right end side of the lower surface of the housing 20 in parallel in the front, rear, left, and right directions. The two terminals arranged in parallel and protruding on the front side of the lower surface of the housing 20 are a third terminal pair 240, and the two terminals arranged in parallel and protruding on the rear side are a fourth terminal pair 250.
In the switch 2 formed in this manner, the pressing operation from the outside received by the operation device 1 is transmitted to the pressing member 21 as the pressing operation from the outside of the housing 20. The pressing member 21 receives an external pressure, moves from a first position on the upper side to a second position on the lower side, and moves from the second position on the lower side to the first position on the upper side when the external pressure is released.
Next, the internal structure of the switch 2 will be described. Fig. 3 is a schematic perspective exploded view showing an example of the switch 2 described in the present application. Fig. 4 is a schematic cross-sectional view showing an example of a cross section of the switch 2 described in the present application. Fig. 4 shows a section cut in a vertical plane including the line a-B shown in fig. 2, from a front perspective.
A space as a housing chamber 201 for housing various components of the electronic circuit can be secured in the housing 20 of the switch 2. An insertion hole 200 penetrating from the outside of the housing 20 is opened in the upper surface of the housing chamber 201, and a pressing member 21 is inserted into the insertion hole 200.
Various components housed in the housing chamber 201 will be described. In the housing chamber 201, various members such as a movable member 26 are disposed in addition to the above-described pressing member 21, supporting member 22, contacted member 23, light emitting unit 24, and light receiving unit 25. A first locking portion 221, which is a part of the support member 22, is disposed on the left side in the housing chamber 201, and a second locking portion 222, which is a part of the support member 22, is disposed near the center in the housing chamber 201. A contacted member 23 is disposed on the right side in the housing chamber 201. A light emitting unit 24 is disposed on the lower right side in the housing chamber 201 in front of the contacted member 23, and a light receiving unit 25 is disposed behind the contacted member 23. The movable member 26 is disposed to extend in the left-right direction in the housing chamber 201, and is locked by the first locking portion 221 and the second locking portion 222 of the support member 22.
The supporting member 22 and the contacted member 23 will be described. Fig. 5 is a schematic external view showing an example of the supporting member 22 and the contacted member 23 of the switch 2 described in the present application. Fig. 5 is a front view of the switch 2 from the front view thereof, illustrating only the supporting member 22 and the contact receiving member 23 disposed in the switch 2. The supporting member 22 and the contacted member 23 illustrated in fig. 3, 4, and 5 are each formed of a conductive metal plate and are disposed in the housing 20 in a spaced manner.
The support member 22 is formed in a thin plate shape and is erected with the normal direction set as the front-rear direction. The lower portion of the support member 22 is formed as a first terminal 220 protruding from the lower surface of the housing 20. The upper portion of the support member 22 located in the housing chamber 201 is divided into two parts, the left side is formed as a first locking portion 221, and the right side is formed as a second locking portion 222. The first locking portion 221 and the second locking portion 222 are bent in the near direction to facilitate locking of the movable member 26.
The contact receiving member 23 is formed in a thin plate shape that is erected with the normal direction being the front-rear direction, and is erected separately from the light emitting unit 24 and the light receiving unit 25 at a position behind the light emitting unit 24 and in front of the light receiving unit 25. The lower portion of the contacted member 23 is formed as a second terminal 230 protruding from the lower surface of the housing 20. The upper portion of the contacted member 23 located in the housing chamber 201 becomes a contacted portion 231 contacted by the movable member 26 when the pressing member 21 is located at the second position and the movable member 26 is pressed by the pressing member 21. In the contacted member 23, a light shielding plate 232 that shields light emitted from the light emitting unit 24 is formed below the contacted portion 231, and a transmission hole 233 through which light emitted from the light emitting unit 24 is transmitted is opened in the light shielding plate 232.
The light emitting unit 24 and the light receiving unit 25 will be described. Fig. 6 is a schematic external view showing an example of the light emitting unit 24 included in the switch 2 described in the present application. The light emitting unit 24 illustrated in fig. 3, 4, and 6 emits light, and the light receiving unit 25 receives the light emitted from the light emitting unit 24. The light emitting unit 24 is configured using a light emitting element 241 such as an LED. The light emitting element 241 of the light emitting unit 24 is molded in a unit case 242 made of resin, and the third terminal pair 240 protrudes from the unit case 242. Two substantially linear lead frames 243 are disposed inside the unit casing 242. One end of the lead frame 243 protrudes from the inside of the unit case 242 to the outside, and serves as the third terminal pair 240. The other end of the lead frame 243 is positioned in the unit case 242, and the light emitting element 241 is mounted thereon and bonded by the wire 244. The light emitting element 241, the lead frame 243, and the wire 244 are disposed at the bottom of a recess formed in the unit case 242. In the recess formed in the unit case 242, a resin having a high transmittance such as an epoxy resin is filled in the manufacturing process, and components such as the light emitting element 241 are molded in the unit case 242 in a state of being visible from the outside. Fig. 6 shows the light emitting cell 24 in a state where the cell casing 242 is filled with a resin having a high transmittance and is visible inside. The light receiving unit 25 is configured using a light receiving element 251 such as a PD (Photo Diode) or PT (Photo Transistor) as a detection unit for detecting light. The structure of the light receiving unit 25 is substantially the same as that of the light emitting unit 24, and therefore, the description of the light emitting unit 24 can be referred to, and detailed description thereof is omitted. In the explanation of the light receiving unit 25, the light emitting element 241 and the third terminal pair 240 explained as the structure of the light emitting unit 24 can be interpreted as the light receiving element 251 and the fourth terminal pair 250.
In the housing 20 of the switch 2, the light emitting unit 24 and the light receiving unit 25 are arranged so that the light emitting element 241 and the light receiving element 251 of the light receiving unit 25 face each other at positions so that the light receiving element 251 of the light emitting unit 24 receives light emitted from the light emitting element 241. The light emitting unit 24 is energized through the third terminal pair 240, and the light emitting element 241 of the light emitting unit 24 emits light. Since the light receiving element 251 of the light receiving unit 25 changes the conduction state when light is detected, an on signal based on the change in the conduction state due to light reception is output from the fourth terminal pair 250.
The movable member 26 will be described. The movable member 26 illustrated in fig. 3 and 4 is a member formed of a conductive metal plate, and is disposed in the housing chamber 201 with the longitudinal direction thereof set to the left-right direction. The left end side of the movable member 26 is locked to the first locking portion 221 and serves as a fixed end serving as a swing fulcrum 260. The right end side of the movable member 26 is a movable contact portion 261 which swings as a free end and contacts and separates from the contacted portion 231 of the contacted member 23 by swinging. The right end side of the movable member 26 is a substantially rectangular light-shielding sheet 262 bent downward from the movable contact portion 261. The light shielding sheet 262 is formed with the normal direction as the front-rear direction, and has a substantially rectangular transmission window 263 through which light emitted from the light emitting unit 24 is transmitted. The light shielding sheet 262 is located in front of the contacted member 23 and behind the light emitting unit 24, and is located between the contacted member 23 and the light emitting unit 24 in a state of being spaced apart from the contacted member 23 and the light emitting unit 24. The movable member 26 is formed with a biasing portion 264 serving as a return spring, which is punched and bent in an arc shape near the center, and the tip of the biasing portion 264 is locked by a second locking portion 222 formed near the center in the storage chamber 201. The urging portion 264 generates a reaction force against the pressing of the pressing member 21.
The pressing member 21 of the switch 2 described above receives a pressure from the outside and moves downward, pressing the movable member 26. When the movable member 26 is pushed, the movable contact portion 261 and the light-shielding sheet 262 on the right end side, which is the free end of the movable member 26, are lowered. As the movable contact portion 261 of the movable member 26 descends, the movable contact portion 261 contacts the contacted portion 231 of the contacted member 23. Since the movable contact portion 261 of the movable member 26 contacts the contacted portion 231 of the contacted member 23, the first terminal 220 of the support member 22 is brought into a conductive state to the second terminal 230 of the contacted member 23. Conduction between the first terminal 220 and the second terminal 230 closes a first circuit outside the switch 2, and an on signal can be output. When the light-shielding plate 262 of the movable member 26 is lowered, the optical path from the light-emitting element 241 of the light-emitting unit 24 to the light-receiving element 251 of the light-receiving unit 25 passes through the transmission window 263 opened in the light-shielding plate 262. Therefore, the light emitted from the light emitting element 241 of the light emitting unit 24 passes through the transmission window 263 provided in the light shielding sheet 262 of the movable member 26, passes through the transmission hole 233 provided in the light shielding plate 232 of the contact member 23, and reaches the light receiving element 251 of the light receiving unit 25. The light receiving element 251 receives light from the light emitting element 241, and can be in an on state in which a second circuit outside the switch 2 is closed, and output an on signal. Further, as the movable contact portion 261 of the movable member 26 descends, the movable contact portion 261 contacts the contacted portion 231 of the contacted member 23. The movable contact portion 261 of the metal movable member 26 collides with the contacted portion 231 of the metal contacted member 23, thereby generating a metal striking sound. The user recognizes the clicking sound of the metal generated by the collision of the movable member 26 with the contacted member 23 as the clicking sound. In addition, the user recognizes the feeling of collision of the movable member 26 with the contacted member 23 as a click feeling. Note that, by appropriately designing the materials and shapes of the movable member 26 and the contacted member 23, the clicking sound and the clicking feeling can be adjusted while controlling the sound generated when the movable member 26 collides with the contacted member 23 and the feeling of collision. For example, by using a material and a shape which hardly generate a clicking sound, muting can be realized at the time of clicking.
When the pressing of the pressing member 21 is released, the movable member 26 is biased upward by the reaction force of the biasing portion 264. The pressing member 21 moves upward by biasing the movable member 26 upward. Since the movable member 26 is biased upward by the biasing portion 264, the movable contact portion 261 and the light-shielding sheet 262 located on the right end side of the movable member 26 rise. As the movable contact portion 261 of the movable member 26 rises, the movable contact portion 261 separates from the contacted portion 231 of the contacted member 23. Since the movable contact portion 261 of the movable member 26 is separated from the contacted portion 231 of the contacted member 23, the first terminal 220 of the supporting member 22 and the second terminal 230 of the contacted member 23 are in an insulated state. The first circuit is open due to the insulation between the first terminal 220 and the second terminal 230. When the light-shielding sheet 262 of the movable member 26 rises, the light emitted from the light-emitting element 241 of the light-emitting unit 24 is shielded by the light-shielding sheet 262, and the second circuit is opened.
Next, the opening and closing of the circuit formed by the switch 2 described in the present application will be described. Fig. 7 and 8 are schematic cross-sectional views showing an example of the switch 2 described in the present application. Fig. 7 and 8 show a cross section cut on a vertical plane including the line a-B shown in fig. 2, from a front view. In fig. 7 and 8, the outer shapes of the supporting member 22 and the contacted member 23 hidden in the housing 20 are shown by broken lines. Fig. 7 shows a state in which the pressing member 21 is not pressed from the outside and is located at the first position above, and fig. 8 shows a state in which the pressing member 21 is lowered by being pressed from the outside and is located at the second position below. When the state illustrated in fig. 7 in which the pressing force is not received is shifted to the state illustrated in fig. 8 in which the pressing force is received, the right end side of the movable member 26 is lowered, and the movable member 26 is brought into contact with the contacted member 23. Since the movable member 26 is in contact with the contacted member 23, the first terminal 220 of the supporting member 22 is brought into a conductive state to the second terminal 230 of the contacted member 23. When the first terminal 220 and the second terminal 230 are electrically connected to each other, a current flows as indicated by solid arrows in fig. 8, and the first circuit is closed and turned on. When the external pressure is released and the state is restored to the state illustrated in fig. 7, the current once flowing is cut off, and the first circuit is opened to be in the off state.
Fig. 9 and 10 are schematic cross-sectional views showing an example of the switch 2 described in the present application. Fig. 9 and 10 show a cross section cut along a vertical plane including the C-D line shown in fig. 2, from a right-hand side view. Fig. 9 shows a state in which the pressing member 21 is not pressed from the outside and is located at the first position above, and fig. 10 shows a state in which the pressing member 21 is lowered by being pressed from the outside and is located at the second position below. When the state illustrated in fig. 9 in which the pressing force is not received is shifted to the state illustrated in fig. 10 in which the pressing force is received, the right end side of the movable member 26 is lowered, and the optical path from the light emitting element 241 of the light emitting unit 24 to the light receiving element 251 of the light receiving unit 25 passes through the transmission window 263 opened in the light shielding sheet 262. Therefore, as shown by solid arrows in fig. 10, light emitted from the light emitting element 241 of the light emitting unit 24 passes through the transmission window 263 opened in the light shielding sheet 262 of the movable member 26, passes through the transmission hole 233 opened in the light shielding plate 232 of the contacted member 23, and reaches the light receiving element 251 of the light receiving unit 25. The light receiving element 251 receives light from the light emitting element 241, and thus, is in an on state in which the second circuit is closed. When the external pressure is released and the state is returned to the state illustrated in fig. 9, the optical path between the light emitting element 241 and the light receiving element 251 is cut off, and the second circuit is opened to be in an off state. As described with reference to fig. 7 to 10, the switch 2 according to the present application opens and closes the first circuit and the second circuit based on the operation of the movable member 26, and therefore, the opening and closing timings of the first circuit and the second circuit can be synchronized.

Fig. 13 shows another embodiment of the switch assembly 4, and the switch 2 included in the switch assembly 4 is shown separately from the substrate 3 in order to facilitate understanding of the relationship between the switch 2 and the substrate 3. The substrate 3 has a first terminal mounting hole 30 and a second terminal mounting hole 31. Conductive metal is previously wired on the substrate 3 by a method such as etching, and the light emitting unit 24 and the light receiving unit 25 are previously mounted on the wiring of the substrate 3 by a method such as surface mounting.

The switch 2 is mounted on the substrate 3 by a mounting method such as soldering, in which the first terminal 220 is inserted into the first terminal mounting hole 30 and the second terminal 230 is inserted into the second terminal mounting hole 31.
As described above, as exemplified in the first to third embodiments, the switch assembly 4 having the switch 2 mounted on the substrate 3 is formed by various methods.
Next, a mounting example of the operation device 1 having the switch 2 described in the present application mounted thereon will be described. Fig. 14 is a block diagram conceptually showing an example of the first embodiment of the operation device 1 described in the present application. The switch 2 has: a contact mechanism 27 using a member such as the supporting member 22 and the contacted member 23, and a non-contact mechanism 28 using a member such as the light emitting unit 24 and the light receiving unit 25. The contact mechanism 27 opens and closes the circuit of the signal control unit 14 as the first circuit by the swing of the movable member 26, and outputs an electronic signal to an external device such as a personal computer. The contactless mechanism 28 opens and closes the circuit of the load control unit 15, which is a second circuit, by the swing of the movable member 26, and turns on the output load unit 130 of the light emitting unit 13. The first embodiment illustrated in fig. 14 is an embodiment in which the first circuit and the second circuit are configured as different circuits, and in the first embodiment, a signal is output to an external device by pressing the pressing operation unit 10 of the pressing operation device 1, and the light emitting unit 13 is caused to emit light. This can provide an effect that the light emitting unit 13 emits light when the operation device 1 is operated, and thus, characteristics such as expanding the functions of the operation device 1 and the switch 2 can be improved. The output load unit 130 is not limited to light emission, and various electric loads such as a speaker for outputting audio and a vibrator for vibrating may be applied. The circuit of the load control unit 15 opened and closed by the contact mechanism 27, the circuit of the signal control unit 14 opened and closed by the contactless mechanism 28, and the like can be designed as appropriate.
Fig. 15 is a block diagram conceptually showing an example of the second embodiment of the operation device 1 described in the present application. The second embodiment is an example in which the first circuit and the second circuit are configured as the same circuit. In the second embodiment, the signal control unit 14 is used as a first circuit that is opened and closed by the contact mechanism 27 and a second circuit that is opened and closed by the contactless mechanism 28. Since the first circuit and the second circuit are the same circuit and the signal control unit 14 is turned on and off by both the contact mechanism 27 and the contactless mechanism 28, even if one of the contact mechanism 27 and the contactless mechanism 28 has a problem, the other can be supplemented. Therefore, characteristics of the operation device 1 and the switch 2 such as improvement in reliability can be improved.
The embodiment of the operation device 1 described in the present application can be developed into various forms regardless of the example of the implementation described with reference to fig. 14 and 15. For example, a mechanism for opening and closing a circuit using an optical element exemplified as the contactless mechanism 28 requires continuous or intermittent energization to the optical element, and has a problem of standby power. In order to solve the above problem, the contact mechanism 27 is applied to a mechanism for opening and closing an electric circuit for supplying electric power to the optical element, thereby suppressing standby power. Specifically, the switch 2 may be configured to be in an off state in which the power supply to the contactless mechanism 28 is cut off during standby. When the contact mechanism 27 is in the on state, the contactless mechanism 28 is energized to be in the on state and the contactless mechanism 28 is operated during the on state or before a predetermined period of time has elapsed since the on state. The contactless mechanism 28, which is turned on by the application of current, can open and close the circuit in accordance with the operation of the push-down operation unit 10 of the operation device 1. The control of the electrical conduction to the optical element by the contact mechanism 27 is not limited to the control of the electrical conduction to the non-contact mechanism 28 in accordance with the operation of the depressing operation portion 10, and may be developed to the control of the electrical conduction to the optical element applied to the position detection (the position operation of the mouse cursor) of the operation device 1. Thus, the operation device 1 and the switch 2 described in the present application can improve various characteristics such as suppression of standby power.
As described above, the operating device 1, the switch 2, and the switch assembly 4 described in the present application include: a contact mechanism 27 using a member such as the supporting member 22 and the contacted member 23, and a non-contact mechanism 28 using a member such as the light emitting unit 24 and the light receiving unit 25. This has an advantageous effect of improving various characteristics such as expansion of functions, improvement of reliability, suppression of standby power, and the like.
The present invention is not limited to the embodiments described above, and can be developed into other various forms. Therefore, the above embodiments are merely illustrative in all aspects and are not restrictive. The technical scope of the present invention is defined by the claims, and is not limited to the description. Further, all changes and modifications that fall within the scope of the claims are to be embraced within the scope of the invention.
For example, in the above-described embodiment, the embodiment has been described as the non-contact mechanism 28, which is an optical mechanism including the light emitting element 241 that emits light and the light receiving element 251 that is a detection unit that detects light to be detected. For example, the present invention can be applied to various types of systems in which the contactless mechanism 28 is configured by using a magnet that generates a magnetic field and a hall element that is a detection unit that detects the magnetic field to be detected.
For example, in the above-described embodiment, the contact mechanism 27 is a system in which the conductive supporting member 22 and the contacted member 23 are used and the first electric circuit is opened and closed by being brought into contact with and separated from the conductive movable member 26, but the present invention is not limited to a conductive member as long as the contact mechanism is an opening and closing mechanism having a contact. That is, the contact and separation of the swinging movable member 26 may open and close the circuit, and the contact member 23 pressed by the movable member 26 may move to open and close the circuit. In the contactless mechanism 28, it is not necessary to make the movable member 26 conductive.
