In addition, regarding the description of the specification and the drawings according to each embodiment, constituent elements having substantially the same functional configuration are denoted by the same reference numerals and overlapping description is omitted.

An operation device 100 according to an embodiment will be described with reference to FIGS. 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 an operated member 1, a holding member 2, a vibration generating member 3, a rotation detecting member 4, a bezel 5, a side plate member 6, and a substrate 7. The control member 8 and the bottom plate member 9 are provided.

The operated member 1 is a disk-shaped member that is rotated by an operator. The operated member 1 has a chamfered portion 11 on the entire edge of the upper edge portion. The operator inputs desired information by rotating the operated member 1 while pressing the operated member 1 toward the holding member 2. The operating device 100 outputs the input information. The operated member 1 is rotatably held by a holding member 2. In the example of FIG. 2, the operated member 1 does not include 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 any 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 (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 transmission member 21 and a support member 22.

The vibration transmitting member 21 is a plate-like member that holds the operated member 1 and is fixed to the support member 22. The vibration transmitting member 21 contacts 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 transmitting member 21. The operated member 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 recessed portion 23 and the lower surface of the operated member 1 are in contact with each other. A viscous material such as viscous grease is preferably applied between the recess 23 and the operated member 1. Thereby, at the time of rotation operation of the to-be-operated member 1, abrasion between the to-be-operated member 1 and the recessed part 23 can be suppressed, and a moderate load can be produced. Moreover, since the recessed part 23 hold | maintains a viscous material inside and prevents the outflow to the exterior, durability with respect to rotation operation of the to-be-operated member 1 improves.

The input member 24 is a member prepared separately from the operated member 1 for an 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) disposed below the icon and connected to the control member 8. (Omitted). 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. Thus, the operator can input 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 a touch button, and may be a hardware button, a rotary switch, or the like. Moreover, the vibration transmission member 21 may include a touch sensor and a liquid crystal display device and be capable of displaying an arbitrary icon.

The support member 22 is a plate-like 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 light-weight and high-rigidity resin such as PBT (polybutylene terephthalate) so that it can be easily vibrated by the vibration generating member 3. The support member 22 has a top plate portion 25 and leg portions 26.

The top plate portion 25 is a plate-like or frame-like portion to which the vibration transmission member 21 is fixed, and is formed to be slightly larger than the vibration transmission 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 disposed so that the outer peripheral portion thereof 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 the 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. 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 elastic member 28 may be provided on each side of the top plate portion 25, or the total length of each side. May be provided. The same applies to the elastic member 29.

The leg portion 26 is a portion extending downward from the bottom surface of the top plate portion 25 as shown in FIG. 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 includes a plurality of leg portions 26, but may include one leg portion 26 or may not include the leg portion 26. 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 any member that generates vibration. Here, FIG. 4 is a side view of the vibration generating member 3. 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 body plate 32, and fixing

members

33 and 34.

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

The magnetic material plate 32 is a plate-like member made of a magnetic material. The magnetic plate 32 is, for example, an iron plate, but is not limited thereto. The magnetic plate 32 is disposed so as to face the coil 31.

The fixing member 34 is a member that fixes the magnetic body 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 plate 32 so that a clearance 35 is formed between the coil 31 and the magnetic 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 plate 32 is attracted to the coil 31 by the magnetic force and is fixed to the magnetic plate 32. The (holding member 2) moves in a 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 plate 32 adsorbed by the magnetic force is separated from the coil 31 and fixed to the magnetic plate 32. The top plate part 25 (holding member 2) moves in a direction in which the magnetic 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 to 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 any sensor that can detect the rotation of the operated member 1 such as a rotary encoder. As the rotation detection member 4, an optical, electromagnetic, or capacitive 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 disposed at any position where the rotation of the operated member 1 can be detected.

The bezel 5 is a frame that covers the upper portion 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. Since the bezel 5 covers the top of the top plate portion 25, the support member 22 can be prevented from coming off. Here, FIG. 6 is a plan view of the operating device 100. As shown in FIG. 6, the bezel 5 is disposed so that the inner peripheral portion thereof faces the outer peripheral portion of the vibration transmitting member 21. A clearance 52 is formed between the inner periphery of the bezel 5 and the outer periphery of the vibration transmission member 21 so that the vibration transmission member 21 can vibrate with respect to the side plate member 6.

As shown in FIG. 2, the side plate member 6 includes a side plate portion 61 and an intermediate plate portion 62. The side plate portion 61 is a part that constitutes the side surface of the casing 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-like portion that is provided inside the side plate portion 61 and is 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. Moreover, the intermediate | middle board part 62 has the through-hole 63 which penetrates each leg part 26 in the position corresponding to each leg part 26, as shown in FIG.

The rotation detecting member 4, the input member 24, and the vibration generating member 3 (coil 31). The control member 8 includes a CPU (Central Processing Unit), a RAM (Random Access Memory), and a ROM (Read Only Memory). When the CPU executes a program stored in the ROM on the RAM, the control of the vibration generating member 3 is realized. 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 constituting the bottom surface of the casing of the operating device 100. The bottom plate member 9 is fixed to the side plate member 6. A 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 illustrating an example of the operation of the controller 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 the fingertip or holds the fingertip on the operated member 1. The operated member 1 is pressed toward the holding member 2 by pressing against the upper surface of the holding member 2. As a result, the lower surface of the operated member 1 reliably contacts the upper surface of the holding member 2.

Next, the operator performs a rotation operation in a desired direction while pressing the operated 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 detection 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 detection member 4 (step S103). The predetermined angle can be arbitrarily set.

When it is detected that the operated member 1 is 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 with respect to the side plate member 6, and the operated member 1 that contacts the holding member 2 in a state where 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 operational feeling when the operated member 1 is rotated by a predetermined angle.

The control member 8 preferably vibrates the holding member 2 when the operator touches the input member 24. Thereby, an operation feeling can be given to the operator who touched the input member 24 (holding member 2).

Further, the operational 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 is different from the operation feeling given when the operator touches the input member 24. The control member 8 changes the strength and frequency of vibration 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 various operational feelings to the operator. be able to.

As described above, the operating device 100 according to the present embodiment causes the operated member 1 to vibrate indirectly by causing the vibration generating member 3 to vibrate the holding member 2, thereby causing the operator to feel the operational feeling of the operated member 1. Can be given. Thus, according to this embodiment, since it is not necessary to connect the to-be-operated member 1 and the vibration generating member 3, the structure of the operating device 100 can be simplified. As a result, the parts and manufacturing process of the operating device 100 can be reduced, and the manufacturing cost can be reduced.

It should be noted that the present invention is not limited to the configuration shown here, such as a combination with other elements in the configuration described in the above embodiment. These points can be changed without departing from the spirit of the present invention, and can be appropriately determined according to the application form.
