Hereinafter, each embodiment of the present invention will be described with reference to the accompanying drawings. Regarding the description of the description and the drawings according to each embodiment, the components having substantially the same functional configuration are designated by the same reference numerals, and the superimposed description will be omitted.

The operation device 100 according to the embodiment will be described with reference to FIGS. 1 to 7. The operation device 100 is a device that outputs information according to the operation of the operator, and is mounted on an arbitrary device such as an audio device or a display device.

First, the configuration of the operating device 100 will be described. FIG. 1 is a perspective view showing an example of the operating device 100. FIG. 2 is an exploded perspective view of the operating device 100 of FIG. Hereinafter, for convenience, the top, bottom, left, and right in the figure will be described as the top, bottom, left, and right of the operating device 100. As shown in FIGS. 1 and 2, the operating device 100 includes the operated member 1, the holding member 2, the vibration generating member 3, the rotation detecting member 4, the bezel 5, the side plate member 6, and the substrate 7. A control member 8 and a bottom plate member 9 are provided.

The operated member 1 is a disk-shaped member that is rotationally operated by an operator. The operated member 1 has a chamfered portion 11 on the edge portion of the upper surface over the entire circumference. The operator inputs desired information by rotating the member to be operated 1 while pressing the member 1 toward the holding member 2. The operation device 100 outputs the input information. The operated member 1 is rotatably held by the holding member 2. In the example of FIG. 2, the operated member 1 does not have a shaft portion and is placed on the holding member 2. However, the operated member 1 may include a shaft portion, and the shaft portion may be rotatably supported by the holding member 2. In either case, the operated member 1 is held so that the lower surface of the operated member 1 comes into contact with the upper surface of the holding member 2 when operated by the operator (when pressed toward the holding member 2). It is held by the member 2.

The holding member 2 is a member that rotatably holds the operated member 1. The holding member 2 includes a vibration transmitting member 21 and a supporting member 22.

The vibration transmission member 21 is a plate-shaped member that holds the operated member 1 and is fixed to the support member 22. The vibration transmission member 21 comes into contact with the operated member 1 and transmits the vibration generated by the vibration generating member 3 to the operated member 1. The vibration transmission member 21 includes a recess 23 and an input member 24.

The recess 23 is a circular recess formed on the upper surface of the vibration transmission member 21. The member to be operated 1 is held in a state of being rotatably fitted in the recess 23. When the operated member 1 is operated, the upper surface of the recess 23 and the lower surface of the operated member 1 come into contact with each other. It is preferable that a viscous material such as viscous grease is applied between the recess 23 and the member 1 to be operated. As a result, it is possible to suppress wear between the operated member 1 and the recess 23 during the rotation operation of the operated member 1 and to generate an appropriate load. Further, since the recess 23 holds the viscous material inside and prevents it from flowing out to the outside, the durability of the member to be operated 1 against the rotation operation is improved.

The input member 24 is a member prepared separately from the operated member 1 for the operator to input information. In the example of FIG. 2, the input member 24 is a touch button, an icon provided so as to be visible from the surface of the vibration transmission member 21, and a touch sensor (illustrated) arranged below the icon and connected to the control member 8. Omitted) and. When the operator touches the icon portion of the vibration transmission member 21, the touch sensor detects the touch and notifies the control member 8 to that effect. As a result, the operator can input the information corresponding to the icon. In the example of FIG. 2, the vibration transmission member 21 includes two input members 24, but may include one or three or more input members 24. Further, the input member 24 is not limited to the touch button, and may be a hardware button, a rotary switch, or the like. Further, the vibration transmission member 21 may be provided with a touch sensor and a liquid crystal display device, and may be capable of displaying an arbitrary icon.

The support member 22 is a plate-shaped member that supports the vibration transmission member 21. As will be described later, the support member 22 vibrates with respect to the side plate member 6 by the vibration generating member 3. The support member 22 is preferably formed of a lightweight and highly rigid resin such as PBT (polybutylene terephthalate) so that the support member 22 can be easily vibrated by the vibration generating member 3. The support member 22 has a top plate portion 25 and a leg portion 26.

The top plate portion 25 is a plate-shaped or frame-shaped portion to which the vibration transmitting member 21 is fixed, and is formed to be one size larger than the vibration transmitting member 21. Here, FIG. 3 is a plan view of the operating device 100 of FIG. In the example of FIG. 3, the operated member 1, the vibration transmitting member 21, and the bezel 5 are removed from the operating device 100. As shown in FIG. 3, the top plate portion 25 is arranged so that its outer peripheral portion faces the inner peripheral portion of the side plate member 6. A clearance 27 is formed between the outer peripheral portion of the top plate portion 25 and the inner peripheral portion of the side plate member 6 so that the top plate portion 25 can vibrate with respect to the side plate member 6. A fixing member 34 is fixed to the lower surface of the top plate portion 25. The fixing member 34 will be described later. In addition, elastic members 28 and 29 are provided on the outer peripheral portion of the top plate portion 25.

The elastic member 28 is an elastic member provided on the side surface of the outer peripheral portion of the top plate portion 25. The elastic member 28 suppresses a collision between the top plate portion 25 and the side plate member 6. The elastic member 29 is an elastic member provided on the upper surface of the outer peripheral portion of the top plate portion 25. The elastic member 29 suppresses the collision between the top plate portion 25 and the bezel 5. The elastic member may be provided on the lower surface of the outer peripheral portion of the top plate portion 25. Further, in the example of FIG. 3, a plurality of elastic members 28 are provided on each side of the top plate portion 25, but one may be provided on each side of the top plate portion 25, or the total length of each side may be provided. It may be provided in. This also applies to the elastic member 29.

As shown in FIG. 2, the leg portion 26 is a portion extending downward from the lower surface of the top plate portion 25. By providing the leg portion 26, the center of gravity of the support member 22 can be lowered and the support member 22 can be stabilized. In the example of FIG. 2, the support member 22 has a plurality of legs 26, but may or may not have one leg 26. Further, in the example of FIG. 2, the vibration transmission member 21 and the support member 22 are prepared as separate bodies, but may be integrally formed.

The vibration generating member 3 is a member that vibrates the holding member 2 with respect to the side plate member 6. The vibration generating member 3 is connected to the control member 8 and controlled. In the example of FIG. 2, the vibration generating member 3 is an actuator, but may be an arbitrary member that generates vibration. Here, FIG. 4 is a side view of the vibration generating member 3. Further, FIG. 5 is a plan view of the operating device 100. In the example of FIG. 5, the operated member 1 and the holding member 2 are removed from the operating device 100. As shown in FIG. 4, the vibration generating member 3 includes a coil 31, a magnetic plate 32, and fixing members 33 and 34.

The coil 31 generates a magnetic force corresponding to the current supplied from the control member 8.

The magnetic plate 32 is a plate-shaped member formed of a magnetic material. The magnetic plate 32 is, for example, an iron plate, but is not limited to this. The magnetic plate 32 is arranged so as to face the coil 31.

As shown in FIG. 5, the fixing member 33 is a member that fixes the coil 31 to the middle plate portion 62 of the side plate member 6. The middle plate portion 62 will be described later. The fixing member 34 is a member that fixes the magnetic plate 32 to the lower surface of the top plate portion 25. The fixing members 33 and 34 fix the coil 31 and the magnetic body plate 32 so that a clearance 35 is formed between the coil 31 and the magnetic body plate 32.

With such a configuration, when the control member 8 energizes the coil 31, the coil 31 generates a magnetic force, and the magnetic body plate 32 is attracted to the coil 31 by the magnetic force, and the top plate portion 25 fixed to the magnetic body plate 32. (Holding member 2) moves in the direction in which the magnetic plate 32 approaches the coil 31. Further, when the control member 8 stops energizing the coil 31, the magnetic force of the coil 31 disappears, and the magnetic body plate 32 attracted by the magnetic force is separated from the coil 31 and fixed to the magnetic body plate 32. The top plate portion 25 (holding member 2) moves in the direction in which the magnetic material plate 32 is separated from the coil 31. Therefore, the control member 8 can vibrate the holding member 2 by alternately repeating ON and OFF of energization of the coil 31. The control member 8 can control the strength and frequency of vibration of the holding member 2 by controlling the magnitude and frequency of the current supplied to the coil 31.

The rotation detection member 4 is a sensor that detects the rotation of the operated member 1 and is connected to the control member 8. The rotation detection member 4 may be an arbitrary sensor capable of detecting the rotation of the operated member 1 such as a rotary encoder. As the rotation detection member 4, an optical, electromagnetic, or capacitance type sensor can be used. In the example of FIG. 2, the rotation detection member 4 is provided on the upper surface of the recess 23, but can be arranged at an arbitrary position where the rotation of the operated member 1 can be detected.

The bezel 5 is a frame body that covers the upper part of the outer peripheral portion of the top plate portion 25, and is fixed to the upper surface of the side plate member 6 by a plurality of screws 51. As described above, the elastic member 29 is provided between the bezel 5 and the outer peripheral portion of the top plate portion 25. By covering the upper part of the top plate portion 25 with the bezel 5, it is possible to prevent the support member 22 from coming off. Here, FIG. 6 is a plan view of the operating device 100. As shown in FIG. 6, the bezel 5 is arranged so that its inner peripheral portion faces the outer peripheral portion of the vibration transmitting member 21. A clearance 52 is formed between the inner peripheral portion of the bezel 5 and the outer peripheral portion of the vibration transmitting member 21 so that the vibration transmitting member 21 can vibrate with respect to the side plate member 6.

The side plate member 6 is a member that constitutes the housing of the operating device 100. As shown in FIG. 2, the side plate member 6 has a side plate portion 61 and a middle plate portion 62. The side plate portion 61 is a portion that constitutes the side surface of the housing of the operating device 100. As described above, the bezel 5 is fixed to the upper surface of the side plate portion 61. The middle plate portion 62 is a plate-shaped portion provided inside the side plate portion 61 and perpendicular to the side plate portion 61. The fixing member 33 of the vibration generating member 3 is fixed to the middle plate portion 62. Further, as shown in FIG. 5, the middle plate portion 62 has a through hole 63 through which each leg portion 26 is inserted at a position corresponding to each leg portion 26.

The substrate 7 is a printed circuit board, and a printed wiring board (not shown) is formed and fixed to the upper surface of the bottom plate member 9. Various electronic circuits including the control member 8 are provided on the upper surface of the substrate 7. The substrate 7 may be fixed to the side plate member 6.

The control member 8 is a circuit that controls the vibration generating member 3 in response to the rotation operation of the operated member 1 and the touch operation of the input member 24 by the operator, and is a rotation detecting member 4, the input member 24, and the vibration generating member. 3 (coil 31) is connected. The control member 8 includes a CPU (Central Processing Unit), a RAM (Random Access Memory), and a ROM (Read Only Memory). The vibration generating member 3 is controlled by the CPU executing the program stored in the ROM on the RAM. In the example of FIG. 2, the control member 8 is one IC (Integrated Circuit), but may be a plurality of ICs.

The bottom plate member 9 is a member that constitutes the bottom surface of the housing of the operating device 100. The bottom plate member 9 is fixed to the side plate member 6. Further, the substrate 7 is fixed to the upper surface of the bottom plate member 9. In the example of FIG. 2, the side plate member 6 and the bottom plate member 9 are prepared as separate bodies, but may be integrally formed.

Next, the operation of the operating device 100 will be described. FIG. 7 is a flowchart showing an example of the operation of the operation device 100. Hereinafter, it is assumed that the rotation detection member 4 constantly detects the rotation of the operated member 1.

First, the operator presses the operated member 1 toward the holding member 2 (step S101). When the operated member 1 is placed on the holding member 2 as in the example of FIG. 2, the operator pinches the chamfered portion 11 of the operated member 1 with a fingertip, or the fingertip is pinched by the operated member 1. By pressing against the upper surface of the member 1, the member to be operated 1 is pressed toward the holding member 2. As a result, the lower surface of the operated member 1 is surely in contact with the upper surface of the holding member 2.

Next, the operator rotates the operated member 1 in a desired direction while pressing the member 1 toward the holding member 2 (step S102). During the rotation of the operated member 1, the rotation (angle) of the operated member 1 is detected by the rotation detecting member 4 and input to the control member 8.

The control member 8 determines whether the operated member 1 has rotated by a predetermined angle based on the angle of the operated member 1 input from the rotation detecting member 4 (step S103). The predetermined angle can be set arbitrarily.

When it is detected that the operated member 1 has rotated by a predetermined angle (step S103), the control member 8 vibrates the vibration generating member 3 (step S104). As described above, when the vibration generating member 3 vibrates, the holding member 2 vibrates against the side plate member 6, and the operated member 1 comes into contact with the holding member 2 while the vibration is pressed toward the holding member 2. The operated member 1 vibrates. As a result, the vibration of the operated member 1 is given to the operator as an operation feeling when the operated member 1 is rotated by a predetermined angle.

It is preferable that the control member 8 vibrates the holding member 2 when the operator touches the input member 24. As a result, the operator who touches the input member 24 (holding member 2) can be given a feeling of operation.

Further, the operation feeling (vibration of the operated member 1 and the holding member 2) given to the operator may be common or different for each operation of the operator. For example, it is conceivable that the operation feeling given when the operator rotates the operated member 1 and the operation feeling given when the operator touch-operates the input member 24 are different. The control member 8 changes the vibration intensity and frequency of the operated member 1 and the holding member 2 by controlling the magnitude and frequency of the current supplied to the coil 31, and gives the operator various operational feelings. be able to.

As described above, the operating device 100 according to the present embodiment indirectly vibrates the operated member 1 by vibrating the holding member 2 by the vibration generating member 3, and gives the operator a feeling of operation of the operated member 1. Can be given. As described above, according to the present embodiment, since it is not necessary to connect the operated member 1 and the vibration generating member 3, the configuration of the operating device 100 can be simplified. As a result, the number of parts and manufacturing processes of the operating device 100 can be reduced, and the manufacturing cost can be reduced.

The present invention is not limited to the configurations shown here, such as combinations with other elements in the configurations and the like described in the above embodiments. These points can be changed without departing from the spirit of the present invention, and can be appropriately determined according to the application form thereof.
