[0012] <Embodiment 1> Refer to Figures 1 to 4 , and a first embodiment of the present disclosure will be described.

[0013] As Figure 1 shown, the operation device 1 in the present embodiment is a button-type operation device 1 provided on a prescribed panel P such as a dashboard of an automobile as a vehicle. In addition, Figure 1 only a part of the panel P is illustrated. Moreover, in particular, the operation device 1 in the present embodiment is a capacitive operation device, and as will be described later, it is configured such that the electrostatic capacitance that may be generated changes according to the operation state of the user approaching, contacting, or pressing the operation part of the operation device, that is, the key top 20, and different operations are accepted according to the change in the electrostatic capacitance. In addition, the operation device may be provided at any place inside the vehicle, and is not limited to the vehicle, and may also be provided in any device or equipment.

[0014] Figure 2 It is a cross-sectional view showing the operation device 1 observed from the side. As Figure 2As shown in (2-1), the operation device 1 is configured to include: a substrate 10 disposed inside the panel P, a key top 20 exposed to the outside from an opening of the panel P, a rubber block 30 disposed between the substrate 10 and the key top 20, and a metal dome 40 disposed between the substrate 10 and the rubber block 30. Hereinafter, each structure and operation will be described.

[0015] The substrate 10 is disposed inside the panel P, that is, inside the vehicle, and various electronic components are mounted thereon. Further, an arithmetic device such as a CPU (Central Processing Unit) 50 is connected to the substrate 10, and the CPU 50 functions to detect signals from the electronic components mounted on the substrate 10 or output signals to the electronic components. In the present embodiment, as will be described later, in particular, an electrode 11 is provided on the substrate 10, and the electrode 11 functions to generate a capacitance with respect to the metal dome 40 and is configured to detect the capacitance using the CPU 50. In addition, the metal dome 40 and the CPU 50 will be described later. Further, in Figure 2 (2-2) to (2-4), the illustration of the CPU 50 is omitted.

[0016] As Figure 1 and Figure 2 shown in (2-1), the key top 20 (operation unit) is a component made of a flat resin or the like and is configured to be exposed to the outside from an opening of the panel P. The key top 20 is configured to be separated from the substrate 10, and a rubber block 30 is disposed between the key top 20 and the substrate 10, and the key top 20 is supported by the rubber block 30. Further, an operation surface is formed on the surface of the key top 20 exposed to the outside, and the operation surface is pressed by the user's finger F from the outside of the panel P toward the inside.

[0017] The rubber block 30 (first elastic member) is an elastic member such as rubber that is respectively in contact with the substrate 10 and the key top 20 and is disposed between them. In the present embodiment, the rubber block 30 is formed in a substantially bowl shape with an opening on the substrate 10 side. Specifically, as Figure 2As shown in (2-1), the rubber block 30 is configured to have an annular base portion 31 with a specified thickness that is located on the opening side of a substantially bowl shape and abuts against the substrate 10, and a substantially circular cover portion 32 that is connected to the base portion 31 and covers the central region of the base portion 31 on the key top 20 side. In other words, the rubber block 30 is formed in such a way that the substantially circular cover portion 32 is connected in a manner that covers the key top 20 side of the annular base portion 31 that abuts against the substrate 10. Thus, the cover portion 32 forms a separated portion that is separated from and exists relative to the substrate 10, and an internal space 30A is formed between the inner surface side of the cover portion 32, which is located on the side opposite to the key top 20 side, and the substrate 10. In addition, the side of the internal space 30A is surrounded by the base portion 31. Further, the rubber block 30 further has a substantially annular support portion 33 on the key top 20 side of the cover portion 32 that abuts against and supports the key top 20.

[0018] The rubber block 30 is configured as described above, and thus, as Figure 2 shown in (2-2), when the user presses the key top 20 toward the substrate 10 with the finger F, as Figure 2 shown in (2-3) and (2-4), the cover portion 32 deforms in a manner that moves toward the substrate 10. Specifically, the rubber block 30 is configured such that when the key top 20 is pressed by the finger F, the pressing force is transmitted to the cover portion 32 via the support portion 33 that supports the key top 20, and due to this pressing force, the connecting portion 32' that connects to the base portion 31 and is located around the cover portion 32 elastically deforms, whereby the cover portion 32 moves toward the substrate 10. In addition, since the rubber block 30 is formed of an elastic member such as rubber, it is configured to generate a restoring force relative to the deformation. Therefore, when the pressing force based on the finger F is released, the elastic deformation of the connecting portion 32' of the cover portion 32 that connects to the base portion 31 is restored, and thus the cover portion 32 on the substrate 10 side moves toward the key top 20 side and returns to its original shape.

[0019] The metal dome sheet 40 (second elastic member) is formed in a dome shape that opens toward the substrate side and is formed of a leaf spring made of metal. Thus, since the metal dome sheet 40 is formed of an elastic member such as a leaf spring having a restoring force, the convex portion on the side opposite to the opening side of the dome shape is pressed toward the opening side, and thus the convex portion is deformed so as to be recessed toward the opening side. When the pressing is released, the recessed convex portion is configured to return to its original shape. Therefore, a tactile feeling can be obtained when the operation key top 20 is operated. Further, the metal dome sheet 40 is disposed in the internal space 30A formed between the rubber block 30 and the substrate 10, and the convex portion on the side opposite to the opening side of the dome shape is provided on the inner surface side of the lid portion 32, that is, the opposing surface of the lid portion 32 with respect to the substrate 10. Further, the length of the metal dome sheet 40 from the opening side to the convex portion is formed to be shorter than the length of the internal space 30A formed between the rubber block 30 and the substrate 10. Thus, the opening side of the metal dome sheet 40 is located at a position separated from the substrate 10.

[0020] The metal dome sheet 40 is configured as described above. Thus, as Figure 2 shown in (2-2), when the user's finger F presses the key top 20 in the direction of the substrate 10, as Figure 2 shown in (2-3) and (2-4), along with the movement of the lid portion 32 of the rubber block 30 in the direction of the substrate 10, it moves in the direction of the substrate 10 and the opening side abuts against the substrate 10, and further deforms in such a manner that the convex portion is recessed. Specifically, when the key top 20 is pressed with the finger F, the metal dome sheet 40 provided on the inner surface side of the lid portion 32 of the rubber block 30 moves in the direction of the substrate 10 together with the lid portion 32. Thus, as Figure 2 shown in (2-3), the opening side of the metal dome sheet 40 abuts against the substrate 10. After that, when the key top 20 is further pressed with the finger F, the lid portion 32 of the rubber block 30 further moves in the direction of the substrate 10. Thus, as Figure 2 shown in (2-4), the convex portion of the metal dome sheet 40 is deformed so as to be recessed in the direction of the substrate 10. Further, since the metal dome sheet 40 is formed of an elastic member such as a leaf spring, it is configured to generate a restoring force with respect to the deformation. Therefore, when the pressing force based on the finger F is released, the metal dome sheet 40 returns from the state where the convex portion is recessed to its original shape. Further, in the present embodiment, the case where the metal dome sheet 40 is made of metal is illustrated. However, as long as it is a conductive member, it may be formed of any member.

[0021] Corresponding to the arrangement of the metal dome sheet 40 described above, the electrode 11 is provided on the substrate 10 as described above. Specifically, as Figure 2As shown in (2-3), when the key top 20 is moved by pressing with the finger F, and thus the metal dome sheet 40 is moved into contact with the substrate 10, an electrode 11 is provided inside the substrate 10 near the position where the metal dome sheet 40 abuts. Therefore, a state is formed in which capacitors C1, C2, and C3 as shown in (3-1) are formed between the metal dome sheet 40 and the electrode 11, and capacitance is generated by these capacitors C1, C2, and C3. In addition, C1 and C3 represent capacitors that can be formed near both ends of the metal dome sheet 40, and C2 represents a capacitor that can be formed near the center of the metal dome sheet 40. Figure 3 As shown in (3-1), a state is formed in which capacitors C1, C2, and C3 are formed between the metal dome sheet 40 and the electrode 11, and capacitance is generated by these capacitors C1, C2, and C3. In addition, C1 and C3 represent capacitors that can be formed near both ends of the metal dome sheet 40, and C2 represents a capacitor that can be formed near the center of the metal dome sheet 40.

[0022] Moreover, as described above, the CPU 50 is connected to the electrode 11, and the CPU 50 (detection unit) detects the capacitance that may be generated in the electrode 11, and accepts the operation performed by the user corresponding to the detected value of the capacitance. In addition, the functions of the CPU 50 in the present embodiment can be realized by the CPU executing a prescribed program.

[0023] Here, with reference to Figures 2 to 4 , the operation of the operating device corresponding to the operation of the user's finger F and the acceptance of the operation by the CPU 50 will be described. In addition, Figure 3 shows the positional relationship between the metal dome sheet 40 and the substrate 10 when the operating device is operated. In addition, in Figure 3 , a part of the structure of the operating device is omitted from the illustration. Figure 4 shows the value of the capacitance detected when the operating device is operated and the load caused by the pressing. In Figure 4 , the horizontal axis represents the moving distance of the metal dome sheet 40, and the vertical axis represents the load based on the finger F and the capacitance.

[0024] First, in the state of (2-1) and (3-1), in other words, when the finger F is not approaching or contacting the key top 20, the CPU 50 detects a reference value of capacitance of 0 and determines that the state is one in which no operation has been performed. After that, in (2-2), (3-2) to (2-3), Figure 2 (2-1), Figure 3 (3-1), in other words, when the finger F is not approaching or contacting the key top 20, the CPU 50 detects a reference value of capacitance of 0 and determines that the state is one in which no operation has been performed. After that, in (2-2), (3-2) to (2-3), Figure 2 (2-2), Figure 3 (3-2) to Figure 2 (2-3), Figure 3In the state of (3-3), in other words, when the user brings the finger F close to or touches the key top 20, or performs an operation such as pressing the key top 20 until the metal dome 40 is about to contact the substrate 10, the CPU 50 detects the first change value of the capacitance starting from the reference value and accepts it as the first operation. In other words, in this case, as the finger F approaches or touches the key top 20, the metal dome 40 approaches the substrate 10, and thus the capacitance of the capacitors C1, C2, and C3 between the metal dome 40 and the electrodes 11 gradually increases, and this value is detected separately from the value in the state where no operation is performed, that is, the reference value. At this time, the capacitance value when the metal dome 40 contacts the substrate 10 is measured in advance, and a value near this measured value (for example, a value equal to or lower than the measured value) is set as the first threshold in the CPU 50. Thus, as Figure 4 shown, during the moving distance of the metal dome 40 until the reference numeral A, in other words, until the metal dome 40 contacts the substrate 10, the CPU 50 detects the first change value of the capacitance within the range that is larger than the reference value set to 0 and does not exceed the first threshold, and accepts it as the first operation. In addition, at this time, the user obtains the operation feeling of approaching or touching the key top 20, or the operation feeling of touching and further pressing.

[0025] After that, in Figure 2 (2-3), Figure 3 In the state of (3-3), in other words, when an operation is performed by pressing the key top 20 with the finger F so that the metal dome 40 contacts the substrate 10, the CPU 50 detects the second change value of the capacitance that is further larger than the above-mentioned first threshold, and accepts it as the second operation. In other words, in this case, as the metal dome 40 further approaches the substrate 10, the capacitance of the capacitors C1, C2, and C3 between the metal dome 40 and the electrodes 11 further increases, and thus the second change value above the first threshold is detected separately from the value in the above-mentioned first operation state. At this time, the capacitance value when the metal dome 40 deforms and further approaches the substrate 10 is measured in advance, and a value near this measured value (for example, a value equal to or lower than the measured value) is set as the second threshold in the CPU 50. Thus, as Figure 4 shown, during the moving distance of the metal dome 40 from the reference numeral A to the reference numeral B, in other words, until the metal dome 40 contacts and deforms the substrate 10, the CPU 5 detects the second change value of the capacitance within the range that is above the first threshold and does not exceed the second threshold, and accepts it as the second operation. In addition, at this time, the user obtains the operation feeling of the half-press state where the key top 20 is pressed into a specified depth and receives the reaction force.

[0026] After that, in Figure 2 (2-4), Figure 3In the state of (3-4)(3-5), in other words, when an operation is performed in which the key top 20 is further pressed by the finger F so that the metal dome 40 abuts against the substrate 10 and the convex portion is further recessed and deformed, the CPU 50 detects a third change value of the electrostatic capacitance that is larger than the above-described second threshold value and accepts it as a third operation. In other words, in this case, as the central position of the metal dome 40 approaches the substrate 10 further, the electrostatic capacitance of the capacitor C2, particularly between the metal dome 40 and the electrode 11, further increases, so that a value above the second threshold value is distinguished from the value in the above-described second operation state and detected. Thus, as Figure 4 shown, during the period when the moving distance of the metal dome 40 is equal to or greater than the reference numeral B in the drawing, in other words, in the state where the metal dome 40 is deformed, the CPU 5 detects a third change value of the electrostatic capacitance above the second threshold value and accepts it as a third operation. In addition, at this time, the user obtains a further click feeling brought about by the deformation of the metal dome 40. In other words, it has an operation feeling of being further pressed in from the half-pressed state.

[0027] In addition, thereafter, when the pressing operation of the finger F with respect to the key top 20 is released, the shapes of the metal dome 40 and the rubber block 30 return to their original states. In other words, from Figure 2 (2-4), Figure 3 the state of (3-4)(3-5) via Figure 2 (2-3), Figure 3 the state of (3-3) becomes Figure 2 (2-2), Figure 3 the state of (3-2), and further becomes the state of (2-1), Figure 2 where the contact of the finger F is also released, Figure 3 (3-1). Then, the value of the electrostatic capacitance detected by the CPU 50 changes from above the above-described second threshold value via less than the second threshold value ( Figure 4 the position of the reference numeral C in the drawing), and further less than the first threshold value ( Figure 4 the position of the reference numeral D in the drawing) to the reference value. Thus, the CPU 50 determines that the operation has been released. In addition, during the release operation, an operation can also be performed to a position where the detected value becomes a second change value that is above the first threshold value and less than the second threshold value, in other words, an operation for restoring the second operation.

[0028] In addition, in the above, a case has been exemplified in which the CPU 50 sets the first threshold value and the second threshold value and accepts three different operations according to whether the detected value of the electrostatic capacitance exceeds each threshold value. However, the CPU 50 can also detect the second operation and the third operation according to whether the detected value of the electrostatic capacitance exceeds the above-described first threshold value and the second threshold value respectively, and accept two different operations.

[0029] Here, a further application example of the above operation device will be described. The operation device in this application example is configured such that the size of the operation surface of the key top 20 is further formed to be larger, and not only pressing operations but also position input operations with respect to the operation surface can be performed. In other words, the operation device is configured to also detect the position of the user's finger F on the operation surface of the key top 20, so that sliding operations and the like can be detected. For example, the operation device mounts further electrodes 11 on the substrate 10 and detects the electrostatic capacitance that may be generated in each electrode 11, whereby the position of the finger F can be detected. Among them, the structure for detecting the position of the finger F on the operation surface of the key top 20 can also be implemented by any structure.

[0030] Moreover, the operation object of the operation device in this application example is a vehicle navigation system mounted on a vehicle. In this case, first, the user performs an operation of bringing the finger F into contact with the key top 20. Then, as the above-described first operation, the operation device accepts an operation to turn on the screen of the vehicle navigation system. Thereby, the screen of the vehicle navigation system is turned on, or the screen is turned on with a further brighter brightness. In addition, the first operation may also be an operation to execute other processes such as displaying a menu of the vehicle navigation system.

[0031] Next, the user presses the key top 20 with the finger F and performs a half-press operation of pressing it into a prescribed depth until a reaction force is felt, as described above. Then, as the above-described second operation, the operation device accepts an operation to move the cursor on the screen of the vehicle navigation system. Thereby, a cursor is displayed on the screen of the vehicle navigation system, and an operation to move the cursor can be performed. Moreover, in this state, the user performs an operation of moving the finger F on the key top 20, whereby the cursor on the screen moves. For example, the user can move the cursor to a desired button.

[0032] Next, the user further presses the key top 20 with the finger F and performs an operation of pressing it until a click feeling is obtained, as described above. Then, as the above-described third operation, the operation device accepts a selection operation based on the cursor on the screen of the vehicle navigation system. Thereby, the button where the cursor is located on the screen of the vehicle navigation system is selected, and an operation corresponding to the button is executed.

[0033] In addition, in the above, a vehicle navigation system is cited as an example of the operation object of the operation device of the present disclosure, but the operation object may also be any device, and the operation accepted by the operation device may also be an operation of any content. In addition, the operation device of the present disclosure is not limited to being mounted on a vehicle, and may also be mounted on any device.
