The contact body 25 is made of a metal plate having elasticity, and has a tongue piece portion 26 and an annular portion 27 formed in a circular ring shape. The tongue piece portion 26 is formed in an inclined state in which the tip is lifted from the inner edge of the annular portion 27 toward the center side.

  The contact body 25 is arranged such that the annular portion 27 is placed on the outer contact 12, and the lower surface of the tongue piece portion 26 faces the central contact 23 at a predetermined interval in the arrangement state. That is, the outer contact 12 and the center contact 23 and the contact body 25 constitute a switch contact portion.

  An elastic member 31 made of rubber or the like is placed on the annular portion 27 of the contact body 25.

  The elastic member 31 includes a cylindrical first protrusion 32 that protrudes upward, a dome part 33 that extends conically downward from a lower end position of the first protrusion 32, and a circular ring part 34 that is provided at the lower end of the dome part 33. And a second protrusion 35 projecting downward provided at the top surface position in the dome portion 33, and the circular ring portion 34 is placed on the annular portion 27 of the contact body 25. The lower surface of the second protrusion 35 is opposed to the tongue piece 26 with a predetermined interval.

  An operation body 41 is placed on the first protrusion 32 of the elastic member 31. Further, an upper case 51 is arranged from above.

  The operating body 41 is made of a hard insulating resin, and has a substantially cylindrical shape whose upper surface is closed by a plate-shaped top surface portion 43. At the center position of the lower surface of the top surface portion 43, a circular recess 44 that is circular and recessed upward is provided. Further, the operating body 41 is provided with linear protrusions 45 extending in the vertical direction at the outer peripheral portion of the side wall that is a symmetrical position passing through the center, and at the lower end portion of the outer periphery of the side wall that is orthogonal to the two linear protrusions 45. The retaining portions 47 extending in the horizontal direction with a predetermined width are provided.

  The upper case 51 is made of a hard insulating resin and has a cylindrical shape. The upper case 51 is arranged on the lower case 1, and is coupled to the lower case 1 by caulking protrusions 3 that are formed to protrude upward at the four corners of the lower case 1 and are bent and crimped inward.

  On the inner wall of the upper case 51, an upper and lower groove 53 is provided at a position corresponding to the linear protrusion 45, and a recess 55 that is recessed outward is provided at an inner wall position corresponding to the retaining portion 47. . The concave portion 55 is provided to constitute a step portion that regulates the upper surface of the retaining portion 47.

  As described above, the conventional push-type switch is configured.

  In the operation, when the upper part of the operation body 41 is pushed down by an operation button (not shown) arranged on the device side, the operation body 41 is lowered, and thereby a pushing force is applied to the elastic member 31.

  And in the predetermined pushing down position of the operation body 41, the dome part 33 of the elastic member 31 elastically deforms with a feeling of moderation. As a result, the tongue piece 26 of the contact body 25 is pushed down at the lower end surface of the second protrusion 35 that moves downward, and the tongue piece 26 comes into contact with the central contact 23. In other words, switching is performed in which the outer contact 12 and the central contact 23 are in a conductive state via the contact body 25, and the first terminal 13 and the second terminal 24 are in a switched-on state.

  Thereafter, when the pressing force to the operating body 41 is released, the dome portion 33 of the elastic member 31 is restored to the original dome shape of the lower opening, and the operating body 41 is pushed up. At the same time, the tongue piece 26 also returns to the original inclined state with the tip positioned on the upper side, and returns to the switch-off state before the operation.

  As prior art document information related to the invention of this application, for example, Patent Document 1 is known.

  The contact body 70 is formed of a metal plate having conductivity and elasticity. As shown in FIG. 2, the first conductive portion 71 formed in a substantially circular shape at the upper position and the circular ring-shaped annular portion 27 formed in the lower position in the same manner as in the prior art are spirally formed. Each part is integrally formed in a shape connected by the formed narrow part 73. In the annular part 27, a tongue piece part 26 formed in an inclined state in which the tip is lifted from the inner edge of the annular part 27 toward the center side is integrally provided as in the prior art. The annular portion 27 and the tongue piece portion 26 are portions forming a part of the switch contact portion.

  The height dimension between the lower surface of the first conductive part 71 and the upper surface of the annular part 27 is set to be slightly shorter than the height dimension of the elastic member 31. Further, the first conductive portion 71 and the annular portion 27 are configured such that the center positions are aligned vertically. Although the shape and size of the first conductive portion 71 are not particularly limited, it is desirable that the upper surface is a shape that can be exposed in a wide area, and is set to a circle having a diameter that is the same as or slightly larger than the upper end of the first protrusion 32. Good.

  The elastic member 31 is assembled in advance in the contact body 70 with the upper surface of the first protrusion 32 and the lower end of the circular ring portion 34 sandwiched between the lower surface of the first conductive portion 71 and the upper surface of the annular portion 27. The bottom surface of the second protrusion 35 of the elastic member 31 is opposed to the tongue piece portion 26 with a predetermined interval in the assembled state in the contact body 70.

  Further, the contact body 70 will be described in detail.

  At the outer edge position of the first conductive portion 71, a first connection portion 75 extending downward via a downward bent portion is provided. Further, a second connection portion 77 extending upward through a bent portion upward is provided at the outer edge position of the annular portion 27.

  The narrow portion 73 has an upper portion integrally formed with the first connection portion 75 and a lower portion integrally formed with the second connection portion 77. The narrow width portion 73 is formed in a spiral shape that becomes narrower as it goes upward due to the difference between the outer edge position of the annular portion 27 and the outer edge position of the first conductive portion 71.

  In FIG. 2, the narrow width portion 73 is formed in a spiral shape at an angle of about 180 degrees, but the spiral angle is not particularly limited. Further, the shape of the narrow portion 73 is not limited to a spiral shape. And the presence or absence of the 1st connection part 75 or the 2nd connection part 77 should just be set suitably. Further, the contact body 70 is not limited to one in which each part is integrally formed from a metal plate, and may be formed into a corresponding shape by combining a plurality of components.

  As described above, the contact body 70 in which the elastic member 31 is previously incorporated is placed on the outer contact 12 of the lower case 1. In the arrangement state, the lower surface of the tongue piece portion 26 provided in the annular portion 27 of the contact body 70 faces the central contact 23 with a predetermined interval.

  An operation body 80 is placed on the first conductive portion 71 of the contact body 70.

  The operating body 80 is formed of a hard insulating resin and has the same outer shape as that of the prior art, but the outer surface thereof is plated with conductivity over the entire surface. This plating becomes the second conductive portion 81. In addition, since the operating body 80 is the same as the conventional one in terms of shape, individual components of the operating body 80 will be described with the same reference numerals as in the conventional case.

  The shape of the operating body 80 will be briefly described. The upper surface is a substantially cylindrical shape closed by a plate-shaped top surface portion 43, and the top surface 43 has a circular shape that is circularly depressed upward at the lower surface center position. A recess 44 is provided. As shown in FIG. 3, two linear protrusions 45 extending in the vertical direction are provided on the outer periphery of the side wall, and the lower end part of the outer periphery of the side wall that is orthogonal to the linear protrusion 45 extends in the horizontal direction. The retaining portions 47 are provided at two locations.

  The operation body 80 may be plated so as to connect at least the upper surface of the plate-like top surface portion 43 and the top surface of the circular recess 44, but when the whole is plated, This is preferable because it can be made cheaper than typical plating and leads to improvement in detection accuracy of change in capacitance.

  The operation body 80 is placed on the contact body 70 with the first conductive portion 71 of the contact body 70 positioned in the circular recess 44. That is, the first conductive portion 71 and the plating on the top surface of the circular recess 44 are in contact with each other. Note that the size of the circular recess 44 is larger than that of the upper portion of the first protrusion 32 and the first conductive portion 71.

  The upper case 51 disposed from above the operation body 80 is coupled to the lower case 1 as in the conventional case. Further, the operating body 80 is in a stopped state in which the upper surface of the retaining portion 47 is in contact with the lower surface of the step portion formed by the concave portion 55 of the inner wall of the upper case 51.

  As described above, the input device according to this embodiment is configured.

  As a mounting state on the device, an operation button (not shown) on the device side is arranged on the operation body 80, and the operation body 80 is mounted so as to be pushed down by a pressing operation on the operation button. Moreover, the 1st terminal 13 of the 1st member 11 and the 2nd terminal 24 of the 2nd member 22 are connected to an electronic circuit part (not shown), and are made into a mounting state. The electronic circuit unit is configured to be able to detect a change in capacitance from the first terminal 13 and detect the presence / absence of a conductive state between the first terminal 13 and the second terminal 24 in a short time. It has become. When detecting a change in capacitance from the first terminal 13, the second terminal 24 is preferably set to the ground potential.

  Next, the operation will be described. When a finger or the like is brought close to the operation button of the device or a touch operation is performed with the finger or the like, the finger or the like approaches the operation body 80 of the input device via the operation button. When a finger or the like approaches, a change in capacitance occurs in the second conductive portion 81 made of plating applied over the entire outer surface of the operation body 80. If the entire outer surface of the operating body 80 is used as the second conductive portion 81 as in this configuration, a wide range is close to a finger or the like, and a change in capacitance is easily obtained.

  The operation body 80 also has a second conductive portion 81 on the top surface of the circular recess 44, and the second conductive portion 81 is in direct contact with the first conductive portion 71. Further, the first conductive portion 71 is integrally formed from the same metal plate as the narrow width portion 73 and the annular portion 27, and the annular portion 27 is electrically connected to the outer contact 12 of the first member 11. Because of these configurations, according to the embodiment, an operation is performed from the first terminal 13 arranged for the switch in the electronic circuit unit in accordance with the proximity or touch operation with the finger or the like to the operation button described above. A change in the capacitance of the body 80 can be detected.

  That is, it is possible to detect from the first terminal 13 via the outer contact 12 that the change in the capacitance of the operating body 80 has been greatly changed by a predetermined value or more by the above-described operation. Can be determined.

  When it is determined that the first input state has been made, the corresponding first function of the device is activated.

  In order to obtain a greater change in capacitance in accordance with the above operation, for example, an operation button of the device having an entire lower surface or the like as a conductive portion, and the conductive portion is used as the first of the operating body 80. The operation buttons may be arranged in contact with the two conductive portions 81. In other words, the conductive part of the operation button may be electrically connected to the first terminal 13 through the first conductive part 71 or the like. As the conductive portion of the operation button, for example, conductive plating may be applied to the entire lower surface of the operation button, or a conductive paint may be applied. Alternatively, a conductive metal plate, conductive film or tape, conductive rubber or the like may be integrated or pasted, or a metal screw arranged from the lower surface side of the operation button or A metal body etc. may be sufficient.

  Since the operation buttons of the device have a larger shape or the like than the operation body 80, the conductive portion can be easily provided in a large setting range, and the conductive portion is disposed at a position close to a finger or the like. Therefore, the effect is great.

  Thereafter, when the operation button of the device is depressed, the operation body 80 is lowered, and the dome portion 33 of the elastic member 31 is elastically deformed with a sense of moderation at a predetermined depressed position. At this time, the first conductive portion 71 of the contact body 70 is also lowered at the same time. However, as the contact body 70, the spiral narrow width portion 73 connected to the first conductive portion 71 is deformed following the deformation. The operation is smooth.

  When the dome portion 33 of the elastic member 31 is elastically deformed, the tongue piece portion 26 of the contact body 70 is pushed down at the lower end surface of the second protrusion 35 of the elastic member 31, and the tongue piece portion 26 becomes the central contact 23. The contacted state, that is, the switch-on state in which the first terminal 13 and the second terminal 24 are electrically connected is brought about.

  The switching of the switching state is detected by the electronic circuit unit as the second input state, and the corresponding second function of the device is activated.

  When the push-down state to the operation button of the device is released, the dome portion 33 of the elastic member 31 is restored to the original dome shape of the lower opening, the first conductive portion 71 and the operation body 80 are pushed up, and the contact body The tongue piece portion 26 of 70 also returns to the original inclined state where the tip is located on the upper side, and returns to the switch-off state before operation.

  As described above, the input device according to this configuration can be provided as a device that can determine the presence or absence of the first input state by detecting a change in capacitance, and obtain the second input state by switching the switch. .

  In the input device, the switching state of the switch can be obtained from the first terminal 13 and the second terminal 24 arranged for a so-called single switch without increasing the number of terminals, and for the switch. It is assumed that a change in electrostatic capacitance can be detected from the first terminal 13 disposed in the circuit. In this case, soldering at the time of mounting can be easily performed.

  In other words, the gist of the present invention is that the capacitance change that occurs during the proximity operation or touch operation of a finger or the like can be detected from the first terminal 13 provided for the switch. There are various modifications. Subsequently, a typical modification will be described.

  FIG. 4 shows a cross-sectional view of the modified example, and this modified example has a configuration in which the operating body 90 is different from the above-described one. Since other configurations are the same as those described above, the same reference numerals are given and description thereof is omitted.

  The operation body 90 having this configuration is made of a hard insulating resin, and the surface thereof is not subjected to conductive plating. The outer shape is the same as the operation body 80 described above.

  The operation body 90 is formed by embedding and fixing a second conductive portion 92 made of a conductive metal plate in a plate-like top surface portion 93. The second conductive portion 92 is provided such that the lower surface is exposed in the circular depression 44 and the upper surface side is exposed on the top surface portion 93 in a wide range.

  The operating body 90 is placed on the contact body 70 with the first conductive portion 71 of the contact body 70 positioned in the circular recess 44. That is, the second conductive portion 92 exposed in the circular depression 44 is in contact with the first conductive portion 71.

  Even in this case, when a finger or the like is brought close to the operation button, a change in the capacitance generated in the second conductive portion 92 can be detected from the first terminal 13. That is, the change in the capacitance generated in the second conductive portion 92 is caused by the first conductive portion 71 in contact with the second conductive portion 92, in other words, from the first terminal 13 of the first member 11 via the contact body 70. It can be configured to be detectable.

  Note that the second conductive portion 92 may be fixed to the operating body 90 by insert molding, adhesion, press-fitting, or the like. In addition, the configuration in which the second conductive portion 92 is electrically connected to the first conductive portion 71 may be other than exposing the lower surface of the second conductive portion 92 in the circular recess 44.

  The two embodiments described above are examples including the operation bodies 80 and 90, but the operation bodies 80 and 90 are not essential. For example, in the case of using the contact body 70 in which the elastic member 31 described above is used, the first conductive portion 71 of the contact body 70 is configured to be fixed to a lower case or the like according to the proximity of a finger or the like. The change in capacitance that occurs can be detected from the first terminal 13 of the first member 11.

  Various modifications of the contact body 70 are possible. For example, the contact body 70 has a first conductive portion 71 at an upper position and a movable portion of the switch contact portion at a lower position, and both are connected by a narrow portion 73 as an integrally formed product. Although described, they may be provided as separate members and electrically connected to each other.

  For example, as an alternative to the first conductive portion 71, the upper end portion of the first protrusion 32 may be applied with a conductive paint or plated with conductivity. Furthermore, it is good also as what comprised at least the upper part of the 1st protrusion 32 with the material containing a conductive filler. As a substitute for the narrow width portion 73, a conductive wire or conductive tape may be used.

  In the above description, the configuration in which the first conductive portion 71 of the contact body 70 is electrically connected to the first member 11 has been described. However, the first conductive portion 71 may be electrically connected to the second member 22. Here, a dedicated terminal may be newly provided as a terminal for detecting a change in capacitance, but a terminal provided for the switch may be shared. The terminals provided for the switch include dummy terminals that are not connected to either the outer contact 12 or the center contact 23. Further, the first conductive portion 71 of the contact body 70 may be configured to be electrically connected to a conductive portion that is disposed so as to be solderable when mounted on a corresponding wiring board.

  The configuration of the switch contact portion is not limited to that described above. The shape of the lower case 1, the shapes of the first member 11 and the second member 22, and the arrangement state on the lower case 1 are not limited. In addition, as the lower case 1, the wiring board is cut into a predetermined shape other than the one made of insulating resin, and the first member 11 and the second member 22 are configured by the wiring pattern formed on the wiring board. It may be what is. Further, the shape of the elastic member 31 and the presence / absence of the upper case 51 are not limited to those described above. Further, in addition to the first conductive portion 71 disposed on the upper portion of the elastic member 31 being electrically connected to the operating bodies 80 and 90, the first conductive portion 71 is disposed on the side surface position of the elastic member 31. In addition, it may be configured such that it is electrically connected to the operating bodies 80 and 90.

  The input device according to the present invention can be mounted on various devices, and is particularly suitable for in-vehicle devices and home appliances because it has a long stroke to be pushed into an operation button. In other words, it is because the switch is not changed in the touched state.

  For example, when the input device is used for the input operation unit of the navigation system, a change in capacitance in the first input state is detected by a proximity operation or a touch operation with a finger on the operation button, and a corresponding operation button is displayed. Illuminate or inform by voice guidance, and then press the operation button to obtain the second input state, determine the corresponding predetermined function, and obtain the device that activates the function Can do.

  Further, in the case where a plurality of input devices according to the present invention are arranged side by side, the first input state is detected in order only by moving the finger along the upper side, and the cursor movement of the display unit and the screen movement are accordingly performed. It is also possible to obtain a device that performs such as.

  The input device according to the present invention can be provided as a combination of a function capable of detecting a change in capacitance and a function of a switch, and is useful for an input operation unit of various electronic devices.
