For example, Patent Document 1 discloses an operating device provided in an audio device and called a cross fader. In the operating device disclosed in Patent Document 1, the operator moves linearly. The operating device is provided with an abutting portion (stopper) that abuts on the moving operator and defines the moving range of the operator.

[0003] Japanese Patent No. 6412653

[0004] With respect to the operator, the user may be required to reduce the repulsive force received by the operator from the abutting portion in order to reliably stop the operator at the position where it abuts on the abutting portion.

[0005] An object of the present disclosure is to obtain an operating device capable of reducing the repulsive force received by the operator from the abutting portion when the operator abuts on the abutting portion.

[0009] An operating device and an acoustic device according to one embodiment of this disclosure will be described in detail below with reference to the drawings. However, this disclosure is not limited to the embodiments described below.

[0010] [Embodiment 1] Figure 1 is a perspective view of the operating device according to Embodiment 1. Figure 2 is a front view of the operating device according to Embodiment 1. The operating device 1 is provided with an operating element 11 that can move in a straight line. Here, we define the X-axis as extending parallel to the direction of movement of the operating element 11. In the following description, the positive direction along the X-axis will be referred to as the right, and the negative direction will be referred to as the left. We also define the Y-axis perpendicular to the X-axis. In addition, the positive direction along the Y-axis will be referred to as the front, and the negative direction will be referred to as the rear. We also define the Z-axis perpendicular to the X-axis and the Y-axis. In addition, the positive direction along the Z-axis will be referred to as the up, and the negative direction will be referred to as the down.

[0011] The operating device 1 comprises a support housing 12, an operating element 11, a movable body 13, a rear gear 14, a rack gear 15, a front gear 16, a switching operation unit 17, and a biasing plate (biasing unit) 18.

[0012] Figure 3 is a perspective view of the support housing from diagonally above and in front. Figure 4 is a perspective view of the support housing from diagonally above and in rear. The support housing 12 is a member that supports and holds the aforementioned operator 11, the movable body 13, the rear gear 14, the rack gear 15, the front gear 16, and the switching operation unit 17.

[0013] The support housing 12 is provided with rails 121 extending horizontally from left to right in the central part in the left-right direction. The operator 11 is supported by the rails 121. The operator 11 is able to move left and right by being supported by the rails 121.

[0014] A first shaft 122a and a second shaft 122b are formed on the top surface 122 of the support housing 12. The first shaft 122a and the second shaft 122b are provided on both the left and right sides, flanking the rail 121.

[0015] The first shaft 122a is formed to protrude upward from the top surface 122. The first shaft 122a is a shaft that rotatably supports the movable body 13.

[0016] The second shaft 122b is formed to protrude upward from the top surface 122. The second shaft 122b is formed at a position further away from the rail 121 than the first shaft 122a. The second shaft 122b is the shaft that rotatably supports the downstream gear 14.

[0017] Figure 5 is a front view of the operator. Figure 6 is a top view of the operator. As described above, the operator 11 is supported by the rail 121 of the support housing 12. The operator 11 is also capable of moving linearly from side to side while supported by the rail 121. The operator 11 comprises a gripping portion 111 that the user directly touches and operates, and a base portion 112 provided below the gripping portion 111. The gripping portion 111 protrudes above the top surface 122 of the support housing 12. The base portion 112 is provided with protruding portions 112a that extend to the left and right.

[0018] Figure 7 is a plan view of the movable body. The movable body 13 is provided on both the left and right sides of the rail 121, but its structure is the same on both sides. The movable body 13 is a disc-shaped member. An insertion hole 131 is formed in the center of the movable body 13 through which the first shaft 122a formed in the support housing 12 is inserted. By inserting the first shaft 122a through the insertion hole 131 of the movable body 13, the movable body 13 is rotatably attached to the top surface 122 of the support housing 12. The movable body 13 has an annular projection 135 that protrudes upward from around the insertion hole 131.

[0019] Gear teeth are formed on a portion of the outer circumference of the moving body 13. In other words, a portion of the moving body 13 is a gear. Furthermore, on the portion of the outer circumference of the moving body 13 where no teeth are formed, a plurality of protrusions 132 are formed that project radially outward. The plurality of protrusions 132 are arranged along the circumferential direction of the moving body 13.

[0020] A contact portion 133 is provided between each of the protrusions 132. The contact portion 133 is held in place by being sandwiched between the protrusions 132. A claw portion 132a is formed at the tip of each protrusion 132, projecting toward the adjacent protrusion 132. The claw portion 132a is formed in a tapered shape, with its width in the direction perpendicular to the direction of movement of the movable body 13 (radial direction) becoming thinner toward the adjacent protrusion 132. The claw portion 132a prevents the contact portion 133, which is held between the protrusions 132, from falling out radially outward.

[0021] As the moving body 13 rotates, one of the multiple contact portions 133 enters the movement path of the operator 11, which moves in the left-right direction, particularly the movement path of the protruding portion 112a. The protruding portion 112a formed on the operator 11 comes into contact with the contact portion 133 that has entered the movement path. In the following description, the contact of the protruding portion 112a with the contact portion 133 will also be simply referred to as the operator 11 coming into contact with the contact portion 133. Figure 8 is a perspective view of the operating device with the operator moved to the left. The operator 11 is restricted from moving any further when it comes into contact with the contact portion 133. Because the moving body 13 is provided on both the left and right sides of the rail 121, the range of movement of the operator 11 in the left-right direction is defined by the contact portion 133.

[0022] Furthermore, if the movable body 13 rotates while the protruding portion 112a is in contact with the contact portion 133, the claw portion 132a formed at the tip of the convex portion 132 of the movable body 13 may get caught. In this case, the movable body 13 may not be able to rotate, or even if it can be rotated, the protruding portion 112a or the claw portion 132a may be damaged. In this embodiment 1, since the claw portion 132a is formed in a tapered shape, even if the movable body 13 rotates while the protruding portion 112a is in contact with the contact portion 133, the protruding portion 112a can smoothly ride up onto the claw portion 132a. Therefore, even if the movable body 13 rotates while the protruding portion 112a is in contact with the contact portion 133, problems such as the movable body 13 not being able to rotate or the protruding portion 112a or the claw portion 132a being damaged are less likely to occur.

[0023] There are various user requirements regarding the behavior of the operator 11 when it comes into contact with the contact portion 133. For example, sometimes it is required that the repulsive force the operator 11 receives from the contact portion 133 be small in order to reliably stop the operator 11 at the position where it comes into contact with the contact portion 133, while other times it is required that the operator 11 receive a certain amount of repulsive force from the contact portion 133 in order to quickly move in the opposite direction after contact.

[0024] In the operating device according to Embodiment 1, the repulsive force applied to the operator 11 can be varied by rotating the movable body 13 and switching the contact portion 133 that enters the movement path of the protruding portion 112a.

[0025] Here, the multiple contact portions 133 are composed of a first contact portion 133a and a second contact portion 133b. In the operating device 1 according to Embodiment 1, the moving body 13 is provided with two first contact portions 133a. Figure 9 is a plan view showing the state in which the operator comes into contact with the first contact portion that has entered the operating path of the operator.

[0026] The contact surface 133a1 of the first contact portion 133a, which the operator 11 contacts, is inclined with respect to the direction of movement of the operator 11 (the direction shown by arrow A) when it has entered the movement path of the operator 11. By inclining the contact surface 133a1 in this way, the repulsive force that the operator 11 receives when it comes into contact with the first contact portion 133a can be reduced. For example, if the first contact portion 133a is made of rubber, it is possible to reduce the repulsive force that the operator 11 receives, including energy loss due to surface friction, to near zero. The first contact portion 133a may also be made of resin.

[0027] The smaller the inclination angle α between the contact surface 133a1 and the direction of movement of the operator 11, the smaller the repulsive force can be. However, if the inclination angle α is made too small, the force that moves the operator 11 in the direction indicated by arrow B will increase, causing an overshoot where the operator 11 moves further from the contact position, which may reduce the accuracy of the position where the operator 11 is stopped.

[0028] In the operating device 1 of Embodiment 1, two first contact portions 133a are provided for one movable body 13. By making the inclination angle α of the two first contact portions 133a different, the user can select a rebound force that better suits their preference.

[0029] The contact surface of the second contact portion 133b is perpendicular to the direction of movement of the operator 11 when it has entered the movement path of the operator 11. In the operating device 1 according to Embodiment 1, three second contact portions 133b are provided for one moving body 13, but by making the coefficients of restitution of the three second contact portions 133b different, the user can select a rebound force that suits their preference. Since the contact surface of the second contact portion 133b is perpendicular to the direction of movement of the operator 11, it is also possible to increase the rebound force received by the operator 11. Note that the coefficients of restitution may differ if the second contact portions 133b are formed of different materials. For example, the second contact portions 133b may be made of resin or rubber.

[0030] Furthermore, the coefficients of restitution may differ if the second contact portions 133b are formed in different shapes. For example, the cross-sectional shape of some of the second contact portions 133b may be semicircular. Figure 10 is a magnified view of the second contact portion. As shown in Figure 10, the coefficient of restitution may be adjusted by forming a gap 134 between the moving body 13 and the second contact portion 133b, which makes it easier to deform the second contact portion 133b when the operator 11 makes contact.

[0031] Unlike the operating device 1 according to Embodiment 1, if the device is configured so that the coefficient of restitution can be changed by replacing the contact portion 133, there are problems such as the replacement work being burdensome for the user or the loss of the replacement contact portion 133. On the other hand, in the operating device 1 according to Embodiment 1, the contact portion 133 that the operator 11 contacts can be easily and reliably switched simply by rotating the movable body 13 without replacing the contact portion 133.

[0032] Figure 11 is a plan view of the operating device with the biasing plate omitted. As shown in Figure 11, the rear gear 14 is provided on both the left and right sides of the rail 121, but its structure is the same on both sides. The rear gear 14 is a disc-shaped gear with multiple teeth formed on its outer circumference. A through hole 141 is formed in the center of the rear gear 14 through which the second shaft 122b formed in the support housing 12 is inserted. By inserting the second shaft 122b through the through hole 141 of the rear gear 14, the rear gear 14 is rotatably mounted on the top surface 122 of the support housing 12. The rear gear 14 mounted on the top surface 122 of the support housing 12 meshes with the gear portion of the movable body 13 which is mounted on the top surface 122 of the support housing 12. Therefore, the movable body 13 rotates in conjunction with the rotation of the rear gear 14.

[0033] Figure 12 is a perspective view of the rack gear. As shown in Figure 12, the rack gear 15 is a rod-shaped member. As shown in Figures 1, 2, and 11, the rack gear 15 is mounted on the support housing 12 so that its longitudinal direction is parallel to the left-right direction. The rack gear 15 is movable from side to side while mounted on the support housing 12.

[0034] The rack gear 15 has teeth that mesh with the downstream gear 14 located on the left side and teeth that mesh with the downstream gear 14 located on the right side. As a result, when the rack gear 15 moves from side to side, both downstream gears 14 located on the left and right sides rotate. In addition, the rack gear 15 has teeth that mesh with the upstream gear 16, which will be described later, and these teeth are formed facing downwards.

[0035] Figure 13 is a perspective view showing the movable body, the downstream gear, the rack gear, the upstream gear, and the switching operation unit. As shown in Figure 13, the upstream gear 16 is a gear that meshes with the rack gear 15. The upstream gear 16 is provided so that its axis of rotation extends in the front-to-back direction. The rotation of the upstream gear 16 causes the rack gear 15 to move from side to side, and the movable body 13 also rotates.

[0036] Figure 14 is a perspective view of the front gear from the rear. Figure 15 is a rear view of the front gear. As shown in Figures 14 and 15, an angle restricting portion 161 for restricting the rotation angle of the front gear is formed on the rear surface of the front gear 16. The angle restricting portion 161 has a plurality of protrusions 161a formed radially outward from the rotation center of the front gear 16.

[0037] The spaces between the multiple protrusions 161a form recesses 161b. As shown in Figure 15, the operating device 1 is provided with an insertion biasing part 162 that is biased in the direction of being inserted into the recesses 161b. When the front gear 16 rotates with the insertion biasing part 162 inserted into the recesses 161b, the protrusions 161a push the insertion biasing part 162 downward as the angle regulating part 161 rotates. As the front gear 16 rotates further, the insertion biasing part 162 is inserted into the recess 161b adjacent to the recess 161b into which it was inserted before rotation.

[0038] Furthermore, if the rotation angle of the preceding gear 16 shifts from the state in which the insertion biasing portion 162 is inserted into the recess 161b, the protrusion 161a is pushed by the biasing force of the insertion biasing portion 162, returning the insertion biasing portion 162 to the rotation angle in which it was inserted into the recess 161b.

[0039] In this way, the rotation angle of the front gear 16 is restricted by the cooperation of the angle restricting part 161 and the insertion biasing part 162. When the front gear 16 is at the restricted rotation angle, the contact part 133 attached to the movable body 13 enters the movement path of the protruding part 112a of the operator 11. This prevents the convex part 132 formed on the movable body 13 from entering the movement path due to a shift in the rotation angle, and prevents the operator 11 from coming into contact with the convex part 132. This prevents problems such as noise generation or failure to obtain the desired repulsive force due to the operator 11 coming into contact with the convex part 132.

[0040] As shown in Figures 1 and 13, the switching operation unit 17 has a knob 171 that can be directly touched and operated by the user, and a gear 172 that is located behind the knob 171 and meshes with the preceding gear 16. The knob 171 protrudes from the front of the support housing 12. The switching operation unit 17 is rotatable around a rotation axis that extends in the front-to-back direction. When the switching operation unit 17 rotates, the gear 172 also rotates, and in conjunction with this, the preceding gear 16 and the movable body 13 rotate. Therefore, the user can easily switch the contact portion 133 that the operator 11 contacts by rotating the switching operation unit 17 by operating the knob 171 to rotate the movable body 13. Furthermore, as described above, the rotation angle of the switching operation unit 17 is adjusted by the angle regulating unit 161 and the insertion biasing unit 162 provided on the preceding gear 16. This eliminates the need for fine adjustment of the amount of rotation of the switching operation unit 17, thereby improving the operability of the switching operation unit 17 for switching the contact unit 133. In other words, the angle regulating unit 161 and the insertion biasing unit 162 constitute a position regulating mechanism that regulates the rotation position of the switching operation unit 17.

[0041] Furthermore, when the switching operation unit 17 is rotated, the rotation direction of the left movable body 13 and the rotation direction of the right movable body 13 are the same. Therefore, even if the arrangement order of the contact parts 133 is the same for the left movable body 13 and the right movable body 13, the order in which the contact parts 133 switch when the switching operation unit 17 is rotated can be made the same. This makes it possible to use the same components for the left movable body 13 and the right movable body 13. This reduces manufacturing costs by reducing the number of parts. In addition, it eliminates the problem of accidentally assembling the left and right movable bodies 13 in reverse during the assembly of the operating device 1.

[0042] As shown in Figures 1 and 2, the biasing plate 18 is a plate-shaped member that covers the upper part of the movable body 13 and the downstream gear 14. Figure 16 is a plan view of the biasing plate. The biasing plate 18 has a hole 181 into which the annular projection 135 of the movable body 13 is inserted.

[0043] The biasing plate 18 is biased to move laterally by a biasing spring 19. Specifically, the biasing plate 18 provided on the left side is biased to move leftward. The biasing plate 18 provided on the right side is biased to move rightward.

[0044] When the biasing plate 18 is biased, the inner surface of the hole 181 engages with the annular convex portion 135, and the moving body 13 is biased to move laterally. As shown in FIG. 7, a slight gap is formed between the inner surface of the insertion hole 131 of the moving body 13 and the outer surface of the first shaft 122a formed on the support housing 12. In FIG. 7, the gap between the inner surface of the insertion hole 131 and the outer surface of the first shaft 122a is enlarged for easy understanding.

[0045] When a gap is formed between the inner surface of the insertion hole 131 and the outer surface of the first shaft 122a, the moving body 13 moves due to the force applied when the operating element 11 abuts against the abutting portion 133. When the moving body 13 moves, the inner surface of the insertion hole 131 may collide with the outer surface of the first shaft 122a, generating noise.

[0046] Therefore, in the operating device 1 according to Embodiment 1, a biasing force in the same direction as the force applied when the operating element 11 abuts against the abutting portion 133 is applied to the moving body 13 by the biasing plate 18 and the biasing spring 19. Even when the overhanging portion 112a of the operating element 11 is not abutting against the abutting portion 133, the moving body 13 moves due to the biasing force, and the gap between the inner surface of the insertion hole 131 and the outer surface of the first shaft 122a is eliminated. Thereby, it is possible to eliminate the noise generated when the operating element 11 abuts against the abutting portion 133.

[0047] Although an example in which the moving body 13 rotates and moves has been described, the moving body 13 may be configured to be linearly moved so that the abutting portion 133 that intrudes into the movement path of the overhanging portion 112a is switched.

[0048] Also, although an example where the operator 11 moves linearly has been described, the operator 11 may move in a manner different from linear movement. For example, the operator may be movable so as to fall in various directions like a joystick. Also in this case, by providing an abutting portion that can be switched by the movement of the moving body in the direction in which the operator falls, it becomes possible to easily change the repulsive force when the operator abuts against the abutting portion. Further, the operator may be rotatable. For example, there is a configuration in which a convex portion protruding from the operator is formed, and the rotation range of the operator is defined by the convex portion abutting against the abutting portion. Also in this case, by providing the abutting portion that enters the movement path of the convex portion so as to be switchable by the movement of the moving body, it becomes possible to easily change the repulsive force when the convex portion abuts.

[0049] In addition, in a state where it has entered the movement path of the operator 11, the first abutting portion 133a having an abutting surface 133a1 inclined with respect to the movement direction of the operator 11 may be held by the support housing 12. Although the switching of the abutting portion 133 by the moving body of the moving body 13 becomes impossible, the effect of reducing the repulsive force that the operator 11 receives from the first abutting portion 133a can be obtained.

[0050] FIG. 17 is a plan view of an audio device provided with the operation device according to Embodiment 1. The audio device 100 includes two jog dials 102 on the top surface 101a of the housing 101. The jog dials 102 are arranged on both the left and right sides of the top surface 101a. In the audio device 100, an operation signal is output by the control unit or an audio signal of a music piece whose reproduction state is adjusted is output according to an operation by the user on the jog dial 102. The output destinations of the operation signal and the audio signal are, for example, a music piece reproduction device (not shown) connected to the audio device 100. In the music piece reproduction device, reproduction of a music piece is performed based on the input operation signal or audio signal.

[0051] The control device 1 is used as a crossfader for the sound device 100. In the sound device 100, the music being played can be switched by changing the position of the control element 11. When the control device 1 is used as a crossfader for the sound device 100, the resistance when moving the control element 11 is very small. As a result, the repulsive force when it comes into contact with the contact element 133 may cause the control element 11 to move to an unintended position. Conversely, when the user wants to quickly move the control element 11 in the opposite direction, they may feel that the repulsive force when it comes into contact with the contact element 133 is too small.

[0052] Thus, in the crossfader of the sound device 100, the required repulsive force when the operator 11 comes into contact with the contact portion 133 tends to vary depending on the purpose of moving the operator 11 and the user's preference. When using the operating device 1 according to Embodiment 1, it is possible to easily switch to the contact portion 133 that provides the desired repulsive force by moving the movable body 13.

[0053] Furthermore, the switching operation unit 17, which is operated when switching the contact portion 133, protrudes from the front of the housing 101. This allows the contact portion 133 to be switched simply by operating the switching operation unit 17 from the outside of the housing 101. Therefore, it is not necessary to remove the top surface 101a of the housing 101 or the like to switch the contact portion 133, making it even easier to switch the contact portion 133. In addition, since the knob 171 of the switching operation unit 17 protrudes from a different front surface than the top surface 101a from which the knob 111 of the operator 11 protrudes, the knob 171 of the switching operation unit 17 does not get in the way when operating the operator 11.

[0054] Although the sound device 100 is equipped with various controls in addition to the crossfader control 11, a description of their functions will be omitted. Furthermore, the control device 1 can be applied to controllers for game consoles and other devices besides the sound device 100.
