Description

The present invention relates to an electronic device, and more particularly to an electronic device provided with a control device using a ferrofluid.

Conventionally, an operating member such as a dial or a slide lever for changing a control value is arranged in an electronic device. Some of these operating members use rubber, highly viscous grease, or the like for the sliding portion to appropriately increase the sliding torque of the operating member so that the user can operate it comfortably. In addition, by adding a click structure to the operation member, one click feeling can be obtained each time the control value is changed, and all of them are devised to improve the operation feeling of the operation member. Is. Further, there are some devised to regulate the rotation operation of the operating member in only one direction.

For example, Patent Document 1 discloses an electronic device capable of avoiding a setting error due to a user's careless rotation operation of the operating member and a setting error when the operating member is rotated without the user's eyes.

Further, as a device for controlling the operation feeling of the operation member, an operation feeling control device using an MR fluid (Magneto Rheological fluid) has been proposed. The MR fluid is obtained by dispersing fine powder of a ferromagnetic material such as iron (about 10 μm in diameter) in a solvent such as oil. When a magnetic field is applied to the MR fluid, the powders are connected in a chain to increase the viscosity of the MR fluid. Further, since the MR fluid has a property that the viscosity of the MR fluid increases as the magnetic field becomes stronger, it is possible to control the viscosity of the MR fluid by controlling the strength of the magnetic field.

As a well-known configuration as an operation feeling control device using MR fluid, there is a configuration in which an MR fluid is enclosed around a rotating moving body (rotor) and a coil is arranged in the vicinity thereof. By changing the current flowing through the coil, the rotational torque of the rotor can be changed, and by connecting an operating member such as a dial in the vicinity of the rotor, the feeling of rotation can be freely changed.

For example, Patent Document 2 discloses an input device that divides one rotation and changes the torque at the division angle by using an MR fluid.

However, in the prior art disclosed in Patent Document 1 described above, the user cannot change the operation feeling of the operation member to a desired operation feeling. Further, in the conventional technique disclosed in Patent Document 2 described above, it is not possible to change the operation feeling of each click within one rotation.

Therefore, the present invention provides an electronic device capable of changing the operation feeling of the operation member to the operation feeling desired by the user.

The electronic device as one aspect of the present invention includes an operating member that is operated by rotational movement or linear movement, a detection means that detects the moving direction and position of the operating member, and a control device that controls the operational feeling of the operating member. The control device is an electronic device having a main body portion, a rotating member rotatably supported by the main body portion, and a magnetic viscous fluid arranged between the main body portion and the rotating member. The operating member has a plurality of set positions, and the operating member has a specific position set from the plurality of set positions. The feeling of operation when moving between and the first set position adjacent to the specific position is that the operating member has a second set position different from the specific position, the specific position, and the second. It is characterized in that the operation feeling when moving to and from a third set position different from the set position of is different.

Other objects and features of the present invention will be described in the following examples.

<Example 1>
Hereinafter, Example 1 of the present invention will be described with reference to FIGS. 1 to 5.

FIG. 1 shows an operation unit 100 provided in an electronic device for realizing the embodiment of the present invention.

FIG. 1A is an external perspective view of the operation unit 100. The operation unit 100 operates by an operation feeling control device (control device) 10 for controlling the feel of each operation unit, a detection device 12 for detecting the rotation direction (movement direction) and position of the operation member, and rotation movement. It is composed of a dial 13 which is a rotation operation member. In this embodiment, the dial 13 which is a rotation operation member that performs a rotation operation is used as an operation member, but the operation member may be a straight-ahead operation member that is operated by a straight-ahead movement such as a slide lever.

FIG. 1B shows a cross-sectional view of the operation unit 100, and FIG. 1C shows an exploded view of the operation unit 100. The operation feeling control device 10 is rotatably supported by the upper case member 101 and the lower case member 102 that also serve as a casing as the main body of the operation feeling control device 10, and the upper case member 101 and the lower case member 102. It is provided with a rotor (rotating member) 103. The rotor 103 has a structure having a shaft portion 103a and a disc portion 103b, and is fixed to the dial 13. Further, an O-ring 104 is provided between the upper case member 101 and the rotor 103, and an O-ring 105 is provided between the upper case member 101 and the lower case member 102. Spaces are provided between the upper case member 101 and the disk portion 103b of the rotor 103, and between the lower case member 102 and the disk portion 103b of the rotor 103, and the MR fluid 106 is injected into the spaces. The lid 107 is fastened to the lower case member 102 with screws 109a, 109b, 109c, 109d. Further, an O-ring 108 is provided between the lower case member 102 and the lid 107. The MR fluid 106 is sealed around the disk portion 103b, and the MR fluid 106 is sealed by the O-ring 104, the O-ring 105, and the O-ring 108. A coil (magnetic field generating portion) 110 is wound around the upper case member 101, and both ends 111a and 111b of the coil 110 are electrically connected to a substrate that controls an energization amount (not shown). When a current is passed through the coil 110, a magnetic field M is generated in the disk portion 103b of the rotor 103. Since the viscosity of the MR fluid 106 is increased by the magnetic field M, the viscous resistance acting between the disk portion 103b and the MR fluid 106 when the rotor 103 rotates is increased. Further, when the value of the current flowing through the coil 110 is increased to generate a stronger magnetic field M, the viscosity of the MR fluid 106 increases, and the viscous resistance between the disk portion 103b and the MR fluid 106 also increases. That is, the rotational torque of the dial 13 fixed to the rotor 103 can be changed by changing the value of the current flowing through the coil 110. A scale 14 is fixed to the dial 13 by a double-sided tape (not shown). A detection device (detection means) 12 which is an absolute (absolute value) type rotary encoder is arranged at a position facing the scale 14. The detection device 12 can detect the position (absolute position) and the rotation direction of the dial 13 by the light emitting / receiving sensor 12a configured on the substrate 12b.

FIG. 2 is a diagram showing a change in the rotational torque of the dial 13, which is the operation feeling of the operation feeling control device 10.

FIG. 2A is a diagram showing the relationship between the current I flowing through the coil 110 and the rotational torque T of the dial 13. When the dial 13 is rotated when the current I = 0, a viscous resistance acts between the disk portion 103b and the MR fluid 106 when the rotor 103 fixed to the dial 13 rotates. The rotation torque T at this time is T = Ta. Since the rotational torque T increases in proportion to the current I, increasing the current I flowing through the coil 110 also increases the rotational torque T of the dial 13.

FIG. 2B shows the relationship between the rotation angle displacement D of the dial 13 and the current I flowing through the coil 110, and the relationship between the rotation angle displacement D of the dial 13 and the rotation torque T of the dial 13. When the rotation angle displacement is 0 to Da, the current I = 0, so the rotation torque T = Ta. In the rotation angle displacements Da to Db, since the current I = Ia, the rotation torque T = Tb. At the rotation angle displacement Db, the current I = 0, and the rotation torque T drops from Tb to Ta.

Since the MR fluid 106 has a constant viscosity when a constant current Ia continues to flow through the coil 110, the dial 13 has a constant rotational torque Tb at any angular displacement while the current Ia continues to flow. That is, in the angular displacements Da to Db, a constant operating force is always felt on the dial 13.

FIG. 2C shows an example of the relationship between the rotational torque T and the rotational angle displacement D of the dial 13 when a time-varying current such as a sine wave or a pulse wave is continuously applied to the coil 110. The dial 13 has a position X, a position Y, a position Z, and a position W, and a position in which the positions X, Y, Z, and W function is set as a set position. The operation when the dial 13 rotates and moves from the position X to the position Y will be described. When the dial 13 moves from the rotation angle displacement 0 to Da and a current Ia is applied to the coil 110, the rotation torque T of the dial 13 becomes Tb. The difference between the rotation torque Tb and the rotation torque Ta in the rotation angle displacement Da becomes the rotation resistance when the dial 13 is rotated, and the rotation resistance becomes the click feeling F when the dial 13 is rotated. The larger the click feeling F, the larger the click feeling F can be obtained. After that, it rotates with a constant rotation torque Tb from the rotation angle displacements Da to Db. When the rotation angle displacement Db is reached, the current flowing through the coil 110 becomes 0, and the rotation torque T of the dial 13 becomes Ta. The difference between the rotation torque Tb and the rotation torque Ta in the rotation angle displacement Db is a sudden torque change, and the torque change is a click feeling F of the dial 13. Similarly, when the dial 13 is rotationally moved from position Y to position Z and when it is rotationally moved from position Z to position W, the torque change is the same as the operation when the dial 13 is rotationally moved from position X to position Y described above. A click feeling F can be obtained with. By repeating the torque change, a time-series click feeling F can be obtained on the dial 13.

FIG. 3 is a flowchart showing an example of a functional block diagram and an operation of the operation unit 100.

FIG. 3A is a diagram showing an example of a functional block diagram of an electronic device including an operation unit 100. The same members as those described with reference to FIG. 1 are designated by the same reference numerals, and the description thereof will be omitted.

The power switch 31 is used to switch between turning on and off the power of the electronic device. The display 32 is provided in an electronic device, and a setting screen is displayed when setting the rotation torque T or the like of the dial 13. A system control unit 33 that controls the entire electronic device and executes a program is mounted on a signal processing board (not shown) mounted inside the electronic device. The program is a program for executing various flowcharts described later in this embodiment. The coil control unit 34 performs energization control such as voltage and timing applied to the coil 110 of the operation feeling control device 100 described above, and the system control unit 33 can arbitrarily set the control value.

FIG. 3B is a flowchart showing the operation of the operation unit 100. Each operation is realized by being executed by the system control unit 33. In step S301, the power of the electronic device including the operation unit 100 is turned on. In step S302, the user rotates the dial 13 in an arbitrary direction. After that, in step S303, the detection device 12 determines whether the currently set position of the dial 13 is the specific position G. If it is determined that the set position is the specific position G, the process proceeds to step S304. In step S304, the current Imax flows and the rotation torque T of the dial 13 becomes heavy, which makes it difficult to rotate the dial 13 from the specific position G. Therefore, the user can grasp the position of the specific position G. On the other hand, when it is determined that the set position is not the specific position G, the current Imax does not flow and the rotation torque T of the dial 13 does not change, so that the user can rotate the dial 13. The process proceeds to step S305, and the display 32 displays a setting screen for allowing the user to select which setting position to change the specific position G to. After that, if the user selects to change the specific position G to another set position in step S306, the process proceeds to step S307. In step S307, the absolute position of the new specific position G is stored in the system control unit 33. If the specific position G is not changed in step S306, the process proceeds to step S308. In step S308, the rotation torque T setting screen is displayed on the display 32. When the user sets an arbitrary rotation torque T in step S309, the torque set value is stored in the system control unit 33 in step 309. Here, the rotational torque and click feeling at each set position can be changed. When the user rotates the dial 13 in step S311, the current I determined in step S310 is applied to the coil 110, and the rotational torque of the dial 13 changes. If the specific position G or rotational torque T is to be reset in step S312, the process proceeds to step S312. In step S313, by pressing an arbitrary operation button on the display 32, the process returns to step S305, and the specific position G and the rotational torque T can be reset. On the other hand, when the specific position G or the rotational torque T is not reset, the dial 13 is used as it is, and finally the power of the electronic device is turned off in step S314.

FIG. 4 shows a dial 13 adapted to a mode dial 31 which is an operation member of a camera. A plurality of marks corresponding to various shooting modes are printed on the top surface of the mode dial 31. The mark is divided by an angle θ with respect to 360 ° per circumference, and a still image shooting mode, a moving image shooting mode, and the like can be set.

FIG. 4A shows a mode in which the mode dial 31 is set to the mode 31a. FIG. 4B shows a mode in which the mode 31d of the mode dial 31 is set. Here, the position with the highest user usage rate in each mode of the mode dial 31 is set as the reference position. The reference position of the mode dial 31 is mode 31a. The mode 31a is set as a specific position G. When the mode dial 31 is rotationally moved from the mode 31a (specific position G) to the mode 31b (first set position), the current I flowing through the coil 110 is increased. As a result, the rotational torque T is compared with the case where the mode dial 31 is rotationally moved from a position other than the mode 31a (second set position) to a position adjacent to the position other than the mode 31a (third set position). Can be made heavier and the click feeling F can be increased. For example, the rotation torque T of the mode dial 31 can be made heavier and the click feeling F can be made larger than in the case of rotationally moving the mode 31d to the mode 31e. Further, when the mode dial 31 is rotationally moved from the mode 31a to the mode 31c, the current I flowing through the coil 110 may be increased. That is, the click feeling F in the case of rotationally moving to the two modes 31b and 31c adjacent to the mode 31a to the mode 31a may be increased as compared with the other cases.

FIG. 5 shows the relationship between the rotational torque T and the rotational angle displacement D of the first embodiment described above.

FIG. 5A shows the relationship between the rotational torque T and the rotational angle displacement D when the mode dial 31 is rotationally moved to the mode 31c, the mode 31a which is a specific position G, the mode 31b, and the mode 31g in order. ..

In the rotation angle displacements 0 to Da, which are the initial rotations in the direction of the mode 31a, which is the specific position G, the current I = 0, in order to detect the rotation direction when the mode dial 31 starts to move from the mode 31c. That is, the change in torque T is eliminated. The rotation direction detection unit 121 detects the rotation direction of the mode dial 31 by the rotation angle displacement Da. After that, when the current Ia is applied to the coil 110 at the rotation angle displacement Da, the rotation torque T of the mode dial 31 becomes Tb. When the rotation angle displacement Db is reached, the current I flowing through the coil 110 becomes 0, and the rotation torque T of the mode dial becomes Ta. The difference between the rotation torque Tb and the rotation torque Ta in the rotation angle displacements Da and Db is a click feeling Fa when the mode dial 31 is rotated.

In the rotation angle displacements Db to Dc, which are the initial rotations in the directions of the mode 31a to the mode D31b, which are specific positions G, the current I = 0, in order to detect the rotation direction when the mode dial 31 starts to move from the mode 31a. That is, the change in torque T is eliminated. The rotation direction detection unit 121 detects the rotation direction of the mode dial 31 by the rotation angle displacement Dc. After that, when the current Ib is applied to the coil 110 at the rotation angle displacement Dc, the rotation torque T of the mode dial 31 becomes Tc. By applying a current Ib larger than the current Ia to the coil 110, the rotational torque T of the mode dial changes to Tc larger than Tb. The difference between the rotation torque Tc and the rotation torque Ta at the rotation angle displacements Dc and Dd is a click feeling Fb when the mode dial 31 is rotated.

In the rotation angle displacements Dd to De, which are the initial stages of rotation in the directions of modes 31b to 31g, the current I = 0, that is, the change in torque T is changed in order to detect the rotation direction when the mode dial 31 starts moving from the mode 31b. I have lost it. The rotation direction detection unit 121 detects the rotation direction of the mode dial 31 by the rotation angle displacement De. After that, when the current Ia is applied to the coil 110 at the rotation angle displacement De, the rotation torque T of the mode dial 31 becomes Tb. When the rotation angle displacement Df is reached, the current I flowing through the coil 110 becomes 0, and the rotation torque T of the mode dial becomes Ta. The difference between the rotation torque Tb and the rotation torque Ta in the rotation angle displacements Dd and De is the click feeling Fa when the mode dial 31 is rotated.

From the above description, the rotation torque Tc when the rotation angle displacements Dc and Dd are reached is larger than the rotation torque Tb when the rotation angle displacements Da, Db, De and Df are reached. Since the relationship is rotational torque Tc-rotational torque Ta> rotational torque Tb-rotational torque Ta, the click feeling Fb at the rotational angle displacements Dc and Dd is larger than the click feeling Fa at the rotational angle displacements Da, Db, De, and Df. .. It is possible to increase the click feeling when turning in the direction of the mode 31a to the mode 31b which is a specific position G. Therefore, the user can grasp by the blind operation that the specific position G exists between the modes 31c and the mode 31g.

FIG. 5B shows the relationship between the rotational torque T and the rotational angle displacement D when the mode dial 31 is rotationally moved to the mode 31f, the mode 31d, the mode 31e, and the mode 31h in order.

In the rotation angle displacements 0 to Da, which is the initial stage of rotation in the directions of the mode 31f to the mode 31d, the current I = 0, that is, the change in the torque T is changed in order to detect the rotation direction when the mode dial 31 starts to move from the mode 31f. I have lost it. The rotation direction detection unit 121 detects the rotation direction of the mode dial 31 by the rotation angle displacement Da. After that, when the current Ia is applied to the coil 110 at the rotation angle displacement Da, the rotation torque T of the mode dial 31 becomes Tb. When the rotation angle displacement Db is reached, the current I flowing through the coil 110 becomes 0, and the rotation torque T of the mode dial becomes Ta. The difference between the rotation torque Tb and the rotation torque Ta in the rotation angle displacements Da and Db is a click feeling Fa when the mode dial 31 is rotated.

In the rotation angle displacements Db to Dc, which are the initial stages of rotation in the directions of modes 31d to 31e, the current I = 0, that is, the change in torque T is changed in order to detect the rotation direction when the mode dial 31 starts moving from the mode 31d. I have lost it. The rotation direction detection unit 121 detects the rotation direction of the mode dial 31 by the rotation angle displacement Dc. After that, when the current Ia is applied to the coil 110 at the rotation angle displacement Dc, the rotation torque T of the mode dial 31 becomes Tb. When the rotation angle displacement Dd is reached, the current I flowing through the coil 110 becomes 0, and the rotation torque T of the mode dial becomes Ta. The difference between the rotation torque Tb and the rotation torque Ta at the rotation angle displacements Dc and Dd is a click feeling Fa when the mode dial 31 is rotated.

In the rotation angle displacements Dd to De, which are the initial stages of rotation in the directions of modes 31e to 31h, the current I = 0, that is, the change in torque T is changed in order to detect the rotation direction when the mode dial 31 starts moving from the mode 31e. I have lost it. The rotation direction detection unit 121 detects the rotation direction of the mode dial 31 by the rotation angle displacement De. After that, when the current Ia is applied to the coil 110 at the rotation angle displacement De, the rotation torque T of the mode dial 31 becomes Tb. When the rotation angle displacement Df is reached, the current flowing through the coil 110 becomes 0, and the rotation torque T of the mode dial 31 becomes Ta. The difference between the rotation torque Tb and the rotation torque Ta in the rotation angle displacement De and Df is the click feeling Fa when the mode dial 31 is rotated.

From the above description, the rotation torque T and the click feeling F when the rotation angle displacements Da, Db, Dc, Dd, De, and Df are reached are the same at any angle displacement. Therefore, the user can grasp by the blind operation that the specific position G does not exist between the modes 31f and the mode 31h.

From the above, the user can change the operation feeling of the operation member to a desired operation feeling based on the specific position of the operation member, so that the user can feel which position the operation member is set to. That is, the user can perform a blind operation of the operation member.
<Example 2>
Hereinafter, Example 2 of the present invention will be described with reference to FIGS. 1, 3, 6, and 7. Those with the same code shall perform the same action.

FIG. 6 shows a dial 13 adapted to an exposure compensation dial 51, which is an operating member of a camera. A plurality of marks corresponding to the exposure compensation level are printed on the top surface of the exposure compensation dial 51, and the exposure compensation level can be set according to the marks. With respect to the mark, the angles of the respective positions of the exposure compensation levels -3 to -2 to -1 to 0 to +1 to +2 to +3 are divided by θ1. It is not possible to rotate and move directly to the exposure compensation level of -3 to +3.

FIG. 6A shows a mode in which the exposure compensation dial 51 is set to level 0 (51a). FIG. 6B shows a mode in which the level -1 (51d) of the exposure compensation dial 51 is set. Level 0 (51a) is set as a specific position G. Here, the position with the highest user usage rate in each level of the exposure compensation dial 51 is set as the reference position. The reference position of the exposure compensation dial 51 is level 0 (51a). Level 0 (51a) is set as a specific position G.

When the exposure compensation dial 51 is rotationally moved from level 0 (51a) to level + 1/3 (51b), the current I flowing through the coil 110 is increased. As a result, the rotational torque T is heavier and the click feeling F is compared with the case where the exposure compensation dial 51 is rotationally moved from a position other than level 0 (51a) to a position adjacent to the position other than level 0 (51a). Can be increased. For example, the rotational torque T of the exposure compensation dial 51 can be made heavier and the click feeling F can be made larger than in the case of rotationally moving the exposure compensation dial 51 from level -1 (51d) to level -2/3 (51e).

Further, it is also possible to specify the operation feeling change range in step S307 of FIG. 3 (b). For example, the current Ia is passed through the coil 110 only between the level 0 (51a) and the level +3 (51m), and the rotational torque Tb is given. On the other hand, between level 0 (51a) and level -3 (51k), the rotational torque Ta is applied without passing the current I through the coil 110.

FIG. 7 shows the relationship between the rotational torque T and the rotational angle displacement D of the second embodiment described above.

In FIG. 7A, the exposure compensation dial 51 is moved to level -1/3 (51c), level 0 (51a), level + 1/3 (51b), and level + 2/3 (51g), which are specific positions G. The relationship between the rotation torque T and the rotation angle displacement D when the rotation is sequentially moved is shown.

From level-1 / 3 (51c) to the rotation angle displacement 0 to Da, which is the initial stage of rotation in the direction of level 0 (51a), which is a specific position G, the exposure compensation dial 51 starts from level-1 / 3 (51c). In order to detect the rotation direction when the vehicle starts to move, the current I = 0, that is, the change in the torque T is eliminated. The rotation direction detection unit 121 detects the rotation direction of the exposure compensation dial 51 by the rotation angle displacement Da. After that, when the current Ia is applied to the coil 110 at the rotation angle displacement Da, the rotation torque T of the exposure compensation dial 51 becomes Tb. When the rotation angle displacement Db is reached, the current I flowing through the coil 110 becomes 0, and the rotation torque T of the dial 13 becomes Ta. The difference between the rotation torque Tb and the rotation torque Ta in the rotation angle displacements Da and Db is a click feeling Fa when the exposure compensation dial 51 is rotated.

In the rotation angle displacements Db to Dc, which are the initial rotations in the direction from level 0 (51a) to level + 1/3 (51b), which are specific positions G, the rotation when the exposure compensation dial 51 starts to move from level 0 (51a). In order to detect the direction, the current I = 0, that is, the change in the torque T is eliminated. The rotation direction detection unit 121 detects the rotation direction of the exposure compensation dial 51 by the rotation angle displacement Dc. After that, when the current Ib is applied to the coil 110 at the rotation angle displacement Dc, the rotation torque T of the exposure compensation dial 51 becomes Tc. By applying a current Ib larger than the current Ia to the coil 110, the rotational torque T of the dial 13 changes to Tc larger than Tb. The difference between the rotation torque Tc and the rotation torque Ta at the rotation angle displacements Dc and Dd is a click feeling Fb when the exposure compensation dial 51 is rotated.

In order to detect the rotation direction when the exposure compensation dial 51 starts to move from the level + 1/3 (51b) in the rotation angle displacements Dd to De, which is the initial rotation of the level + 1/3 (51b) to the level + 2/3 (51 g). In addition, the current I = 0, that is, the change in the torque T is eliminated. The rotation direction detection unit 121 detects the rotation direction of the exposure compensation dial 51 by the rotation angle displacement De. After that, when the current Ia is applied to the coil 110 at the rotation angle displacement De, the rotation torque T of the exposure compensation dial 51 becomes Tb. When the rotation angle displacement Df is reached, the current I flowing through the coil 110 becomes 0, and the rotation torque T of the dial 13 becomes Ta. The difference between the rotation torque Tb and the rotation torque Ta in the rotation angle displacement De and Df is the click feeling Fa when the exposure compensation dial 51 is rotated.

From the above description, the rotation torque Tc when the rotation angle displacements Dc and Dd are reached is larger than the rotation torque Tb when the rotation angle displacements Da, Db, De and Df are reached. Since the relationship is rotational torque Tc-rotational torque Ta> rotational torque Tb-rotational torque Ta, the rotational torque Tc and click feeling Fb at the rotational angle displacements Dc and Dd are the rotational torques at the rotational angle displacements Da, Db, De, and Df. It is larger than Tb and click feeling Fa. The click feeling F when turning in the direction from level 0 (51a) to level + 1/3 (51b), which is a specific position G, can be increased. Therefore, the user can grasp by the blind operation that the specific position G exists between the level-1 / 3 (51c) and the level +2/3 (51g).

In FIG. 7B, the exposure compensation dial 51 is rotated to level -1 and 1/3 (51f), level -1 (51d), level -2/3 (51e), and level -1/3 (51h) in this order. The relationship between the rotation torque T and the rotation angle displacement D when moving is shown.

When the rotation angle displacement 0 to Da, which is the initial rotation of the exposure compensation dial 51 in the direction of level -1 and 1/3 (51f) to level -1 (51d), the exposure compensation dial 51 is set to level -1 and 1 /. In order to detect the rotation direction when moving from 3 (51f), the current I = 0, that is, the change in the torque T is eliminated. The rotation direction detection unit 121 detects the rotation direction of the exposure compensation dial 51 by the rotation angle displacement Da. After that, when the current Ia is applied to the coil 110 at the rotation angle displacement Da, the rotation torque T of the exposure compensation dial 51 becomes Tb. When the angular displacement Db is reached, the current I flowing through the coil 110 becomes 0, and the rotational torque T of the exposure compensation dial 51 becomes Ta. The difference between the rotation torque Tb and the rotation torque Ta in the rotation angle displacements Da and Db is a click feeling Fa when the exposure compensation dial 51 is rotated.

In the rotation angle displacements Db to Dc, which are the initial rotations in the direction of level-1 (51d) to level-2 / 3 (51e), the rotation direction when the exposure compensation dial 51 starts to move from level-1 (51d) is detected. Therefore, the current I = 0, that is, the change in the torque T is eliminated. The rotation direction detection unit 121 detects the rotation direction of the exposure compensation dial 51 by the rotation angle displacement Dc. After that, when the current Ia is applied to the coil 110 at the rotation angle displacement Dc, the rotation torque T of the exposure compensation dial 51 becomes Tb. When the rotation angle displacement Dd is reached, the current I flowing through the coil 110 becomes 0, and the rotation torque T of the exposure compensation dial 51 becomes Ta. The difference between the rotation torque Tb and the rotation torque Ta in the rotation angle displacements Dc and Dd is a click feeling Fa when the exposure compensation dial 51 is rotated.

In the rotation angle displacements Dd to De, which is the initial stage of rotation in the direction of level-2 / 3 (51e) to level-1 / 3 (51h), the exposure compensation dial 51 starts to move from level-2 / 3 (51e). In order to detect the rotation direction, the current I = 0, that is, the change in the torque T is eliminated. The rotation direction detection unit 121 detects the rotation direction of the exposure compensation dial 51 by the rotation angle displacement De. After that, when the current Ia is applied to the coil 110 at the rotation angle displacement De, the rotation torque T of the exposure compensation dial 51 becomes Tb. When the angular displacement Df is reached, the current flowing through the coil 110 becomes 0, and the rotational torque T of the exposure compensation dial 51 becomes Ta. The difference between the rotation torque Tb and the rotation torque Ta in the rotation angle displacements DF and Df is the click feeling Fa when the exposure compensation dial 51 is rotated.

From the above description, the rotation torque T and the click feeling F when the rotation angle displacements Da, Db, Dc, Dd, De, and Df are reached are the same at any angle displacement. Therefore, the user can grasp by the blind operation that the specific position G does not exist between the level -1 and 1/3 (51f) to the level -1/3 (51h).

From the above, the user can change the operation feeling of the operation member to a desired operation feeling based on the specific position of the operation member, so that the user can feel which position the operation member is set to. That is, the user can perform a blind operation of the operation member.
<Example 3>
Hereinafter, Example 3 of the present invention will be described with reference to FIGS. 1, 3, 8, and 9. Those with the same code shall perform the same action.

FIG. 8 shows a dial 13 adapted to an exposure compensation dial 71, which is an operating member of a camera. A plurality of marks corresponding to the exposure compensation level are printed on the top surface of the exposure compensation dial 71, and the exposure compensation level can be set according to the marks. Further, the exposure compensation dial 71 has a custom position (〇) (71z). For a plurality of marks corresponding to the exposure compensation level, the angles of the positions of the exposure compensation levels -3 to -2 to -1 to 0 to +1 to +2 to +3 are divided by θ1. It can be rotated and moved from exposure compensation level -3 to custom position (〇) to +3, and the angle of each position is divided by θ2. Further, the exposure compensation dial 71 is set to the custom position (〇) (71z). The custom positions (〇) and (71z) are set as specific positions G. The specific position G can be freely set by the user from each position in step S306 of FIG. 3 (b). Rotate the exposure compensation dial 71 from the custom position (〇) (71z) to the level +3 (71y). At that time, compared with the case of rotationally moving from a position other than the custom position (〇) (71z) to a position adjacent to the position other than the custom position (〇) (71z) and not the custom position (〇) (71z). Therefore, the rotational movement distance (pitch) is large. For example, the pitch is larger than the case of rotationally moving from level +2 (71t) to level +2 and 1/3 (71s). The pitch can be increased by changing the flow of a time-varying current such as a sine wave or a pulse wave flowing through the coil 110.

FIG. 9 shows the relationship between the rotational torque T and the rotational angle displacement D of the third embodiment described above.

Rotation when rotating the exposure compensation dial 71 to level -3 (71x), custom position (〇) (71z), level + 3 (71y), level + 2 and 2/3 (71w), which are specific positions G. The relationship between the torque T and the rotation angle displacement D is shown.

The exposure compensation dial 71 starts to move from level -3 (71x) at the rotation angle displacement 0 to Da, which is the initial rotation in the direction from level -3 (71x) to the custom position (〇) (71z) which is a specific position G. In order to detect the rotation direction at the time, the change of the current I = 0, that is, the torque T is eliminated. The rotation direction detection unit 121 detects the rotation direction of the exposure compensation dial 71 by the rotation angle displacement Da. After that, when the current Ia is applied to the coil 110 at the rotation angle displacement Da, the rotation torque T of the exposure compensation dial 71 becomes Tb. When the rotation angle displacement Db is reached, the current flowing through the coil 110 becomes 0, and the rotation torque T of the dial 13 becomes Ta. The difference between the rotation torque Tb and the rotation torque Ta in the rotation angle displacements Da and Db is a click feeling Fa when the exposure compensation dial 71 is rotated.

In the rotation angle displacements Db to Dc, which are the initial rotations in the direction from the custom position (〇) (71z) to the level + 3 (71y), which is the specific position G, the exposure compensation dial 71 is from the custom position (〇) (71z). In order to detect the rotation direction when the vehicle starts to move, the current I = 0, that is, the change in the torque T is eliminated. The rotation direction detection unit 121 detects the rotation direction of the exposure compensation dial 71 by the rotation angle displacement Dc. After that, when the current Ia is applied to the coil 110 at the rotation angle displacement Dc, the rotation torque T of the exposure compensation dial 71 becomes Tb. The difference between the rotation torque Tb and the rotation torque Ta at the rotation angle displacements Dc and Dd on the coil 110 is a click feeling Fa when the exposure compensation dial 71 is rotated.

In the rotation angle displacements Dd to De, which are the initial rotations in the directions of level +3 (71y) to level +2 and 2/3 (71w), the exposure compensation dial 71 detects the rotation direction when the exposure compensation dial 71 starts moving from level +3 (71y). Therefore, the current I = 0, that is, the change in the torque T is eliminated. The rotation direction detection unit 121 detects the rotation direction of the exposure compensation dial 71 by the rotation angle displacement De. After that, when the current Ia is applied to the coil 110 at the rotation angle displacement De, the rotation torque T of the exposure compensation dial 71 becomes Tb. When the angular displacement Df is reached, the current flowing through the coil 110 becomes 0, and the rotational torque T of the dial 13 becomes Ta. The difference between the rotation torque Tb and the rotation torque Ta in the rotation angle displacement De and Df is the click feeling Fa when the exposure compensation dial 71 is rotated.

From the above description, the rotation torque T and the click feeling F when the rotation angle displacements Da, Db, Dc, Dd, De, and Df are reached are the same at any angle displacement.

On the other hand, the amount of angular displacement will be described. Since the angular displacement amount θ2 between the level -3 (71x) and the custom position (〇) (71z) and the angular displacement amount θ2 between the custom position (〇) (71z) and the level + 3 (71y) are the same, the rotational movement distance ( Pitch) is the same. However, since the angular displacement amount θ1 between the level +3 (71y) to the level +2 and 2/3 (71w) is smaller than the angular displacement amount θ2, the rotational movement angle (movement pitch) is small. The rotational movement angle (movement pitch) of the exposure compensation dial 71 can be changed by changing the flow of a time-changing current such as a sine wave or a pulse wave flowing through the coil 110. Therefore, the user can grasp by the blind operation that the specific position G exists between the level -3 (71x) and the level +2 and 2/3 (71w). In step S308 of FIG. 3B, it is possible to set the rotation movement angle (movement pitch) of each position. As in this embodiment, the angle displacement amount θ2 between the level -3 (71x) and the custom position (〇) (71z) and the level + 3 (71y), and the angle between the level + 3 (71y) and the level -3 (71x). The displacement amount θ1 can be set.

From the above, the user can change the operation feeling of the operation member to a desired operation feeling based on the specific position of the operation member, so that the user can feel which position the operation member is set to. That is, the user can perform a blind operation of the operation member.
<Example 4>
Hereinafter, Example 4 of the present invention will be described with reference to FIGS. 1, 3, and 10. Those with the same code shall perform the same action.

FIG. 10 shows a dial 13 adapted to an exposure compensation dial 91, which is an operating member of a camera. A plurality of marks corresponding to the exposure compensation level are printed on the top surface of the exposure compensation dial 91, and the exposure compensation level can be set according to the marks. With respect to the mark, the angles of the respective positions of the exposure compensation levels -3 to -2 to -1 to 0 to +1 to +2 to +3 are divided by θ1. It is not possible to rotate and move directly to the exposure compensation level of -3 to +3.

FIG. 10A shows a mode in which the exposure compensation dial 91 is set to level +2 (91a). FIG. 10B shows a mode in which the level-2 (91d) of the exposure compensation dial 91 is set.

Level +2 (91a) and level-2 (91d) are set as specific positions G. In this case, level +2 (91a) is set to position G1 and level-2 (91d) is set to position G2. In step S305 of FIG. 3B, it is possible to set a plurality of specific positions G.

When the exposure compensation dial 91 is rotationally moved from level +2 (91a) to level +2 and 1/3 (91b), the current I flowing through the coil 110 is changed. As a result, the rotational torque T and the click feeling F can be changed as compared with the case where the rotational movement is performed from a position other than the level +2 (91a) to a position adjacent to the position other than the level +2 (91a).

Similarly, when the exposure compensation dial 91 is rotationally moved from level-2 (91d) to level-2 and 1/3 (91e), the current flowing through the coil 110 is changed. As a result, the rotational torque T and the click feeling F can be changed as compared with the case of rotationally moving from a position other than level-2 (91d) to a position adjacent to the position other than level-2 (91d). ..

As described above, a plurality of specific positions G can be set. In this embodiment, two specific positions G, G1 and G2, are set on the exposure compensation dial 91. The rotational torque and click feeling of the exposure compensation dial 91 can be changed by changing the flow of the time-changing current flowing through the coil 110 when the coil 110 is rotationally moved from each of the specific positions G1 and G2. At that time, different torques and click feelings are given to each of the specific positions G1 and G2. Therefore, the user can grasp by the blind operation that there are two specific positions G on the exposure compensation dial 91.

From the above, the user can change the operation feeling of the operation member to a desired operation feeling based on the specific position of the operation member, so that the user can feel which position the operation member is set to. That is, the user can perform a blind operation of the operation member.
<Example 5>
Hereinafter, Example 5 of the present invention will be described with reference to FIGS. 1, 3, 11, and 12. Those with the same code shall perform the same action.

FIG. 11 shows a dial 13 adapted to an exposure compensation dial 501, which is an operating member of a camera. A plurality of marks corresponding to the exposure compensation level are printed on the top surface of the exposure compensation dial 501, and the exposure compensation level can be set according to the marks. With respect to the mark, the angles of the respective positions of the exposure compensation levels -3 to -2 to -1 to 0 to +1 to +2 to +3 are divided by θ1. It is not possible to rotate and move directly to the exposure compensation level of -3 to +3. Further, the exposure compensation dial 501 is set to level 0 (501a). Level 0 (501a) is set as a specific position G.

In the direction away from level 0 (501a), level 0 (501a), level + 1/3 (501b), level + 2/3 (501c), level +1 (501d), level +1 and 1/3 (501e), level +1 When rotating the exposure compensation dial 501 in the order of 2/3 (501f), level +2 (501g), level +2 and 1/3 (501h), level +2 and 2/3 (501k), level +3 (501m). , The current I flowing through the coil 110 is increased every time the coil 110 is moved by one position. As a result, the rotational torque T can be gradually increased as the position moves away from the specific position G, level 0 (501a).

In the direction away from level 0 (501a), level 0 (501a), level-1 / 3 (501n), level-2 / 3 (501p), level-1 (501q), level-1 and 1/3 (501r). ), Level-1 and 2/3 (501s), Level-2 (501t), Level-2 and 1/3 (501x), Level-2 and 2/3 (501y), Level-3 (501z), and so on. When the exposure compensation dial 501 is rotationally moved, the current I flowing through the coil 110 is increased each time the exposure compensation dial 501 is moved by one position. As a result, the rotational torque T can be gradually increased as the position moves away from the specific position G, level 0 (501a).

In the direction of approaching level 0 (501a), level +3 (501m), level +2 and 2/3 (501k), level +2 and 1/3 (501h), level +2 (501g), level +1 and 2/3 (501f). ), Level +1 and 1/3 (501e), Level +1 (501d), Level + 2/3 (501c), Level + 1/3 (501b), Level 0 (501a), and so on. , The current I flowing through the coil 110 is reduced every time the coil 110 is moved by one position. As a result, the rotational torque T can be gradually reduced as the position moves closer to the specific position G, level 0 (501a).

In the direction of approaching level 0 (501a), level-3 (501z), level-2 and 2/3 (501y), level-2 and 1/3 (501x), level-2 (501t), level-1 and so on. 2/3 (501s), level-1 and 1/3 (501r), level-1 (501q), level-2 / 3 (501p), level-1 / 3 (501n), level 0 (501a) in that order. When the exposure compensation dial 501 is rotationally moved, the current I flowing through the coil 110 is reduced each time the exposure compensation dial 501 is moved by one position. As a result, the rotational torque T can be gradually reduced as the position moves closer to the specific position G, level 0 (501a).

FIG. 12 shows the relationship between the rotation torque T and the rotation angle displacement D of a part of the above-mentioned Example 5.

In FIG. 12A, the exposure compensation dial 501 is rotated and moved to the specific position G, that is, level 0 (501a), level + 1/3 (501b), level + 2/3 (501c), and level +1 (501d). The relationship between the rotation torque T and the rotation angle displacement D at the time of making the rotation is shown. As the exposure compensation dial 501 rotates to level 0 (501a), level + 1/3 (501b), level + 2/3 (501c), and level +1 (501d), the rotational torque increases. Therefore, the user can experience that the rotational torque gradually increases when the rotational movement is performed in the direction of level 0 (501a) to level +1 (501d).

In FIG. 12B, the exposure compensation dial 501 is rotated and moved in order to level + 1 (501d), level + 2/3 (501c), level + 1/3 (501b), and level 0 (501a) which is a specific position G. The relationship between the rotation torque T and the rotation angle displacement D at the time of making the rotation is shown. As the exposure compensation dial 501 rotates to level + 1 (501d), level + 2/3 (501c), level + 1/3 (501b), and level 0 (501a), the rotational torque decreases. Therefore, the user can experience that the rotational torque gradually decreases when the rotational movement is performed in the direction of level +1 (501d) to level 0 (501a).

As described above, as the specific position G is set and the position moves away from the specific position G, the rotational torque of the exposure compensation dial 501 can be gradually increased. Further, the rotational torque of the exposure compensation dial 501 can be gradually reduced as the position moves closer to the specific position G.

From the above, the user can change the operation feeling of the operation member to a desired operation feeling based on the specific position of the operation member, so that the user can feel which position the operation member is set to. That is, the user can perform a blind operation of the operation member.
<Example 6>
Hereinafter, Example 6 of the present invention will be described with reference to FIGS. 1, 13, and 14. Those with the same code shall perform the same action.

FIG. 13 shows a dial 13 adapted to the exposure compensation dial 701, which is an operating member of the camera. A plurality of marks corresponding to the exposure compensation level are printed on the top surface of the exposure compensation dial 701, and the exposure compensation level can be set according to the marks. Further, the exposure compensation dial 701 does not have a specific position G.

FIG. 13A shows a mode in which the exposure compensation dial 701 is set to level +3 (701a). When the exposure compensation dial 701 is rotationally moved clockwise (CW), a constant current Ix continues to flow through the coil 110. As a result, when the exposure compensation dial 701 is rotationally moved in the clockwise direction (CW), a constant rotational torque Tx is obtained. For example, when rotationally moving in the clockwise direction (CW), which is the direction from level +3 (701a) to level-3 (701z), a constant rotational torque Tx is obtained. Further, the constant amount of current I flowing through the coil 110 can be changed.

FIG. 13B shows a mode in which the level -3 (701z) of the exposure compensation dial 701 is set. When the exposure compensation dial 701 is rotationally moved in the counterclockwise direction (CCW), a constant current Iy is continuously applied to the coil 110. As a result, when the exposure compensation dial 701 is rotationally moved in the counterclockwise direction (CCW), a constant rotational torque Ty is obtained. For example, when rotationally moving in the counterclockwise direction (CCW), which is the direction from level -3 (701z) to level +3 (701a), a constant rotational torque Ty is obtained. Further, the constant amount of current I flowing through the coil 110 can be changed.

FIG. 14 shows the relationship between the current I and the rotational torque T. The relationship is such that the current Iy> Ix and the torque Ty> Tx. Therefore, a larger torque can be obtained when the exposure compensation dial 701 is rotationally moved in the counterclockwise direction (CCW) than when the exposure compensation dial 701 is rotationally moved in the clockwise direction (CW).

As described above, the constant amount of current I flowing through the coil 110 can be changed to make the rotational torque of the exposure compensation dial 701 constant in any rotational direction. Therefore, the user can customize the feel of the operating member to the user's favorite feel.

From the above, the user can change the operation feeling of the operation member to the desired operation feeling, so that the user can customize the feeling to his / her preference.

Further, when the operating member is not the exposure compensation dial 701 which is a rotation operating member but a linear operating member, when the linear operating member is moved to one side, a constant current Ix is continuously passed through the coil 110 to the other side. A constant current Iy may be continuously applied to the coil 110 when the coil 110 is moved.

Although the preferred embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and various modifications and modifications can be made within the scope of the gist thereof.
