Description

[Technical Field]

[0001] The present invention relates to an operating device and an audio device. [Background technology]

[0002] Conventionally, various audio devices equipped with jog dials have been known. For example, in the field of DJ equipment, there is known an audio device equipped with a rotary operator called a motorized jog dial, which has a base (platter) that is rotated by a motor and an operation panel (vinyl) placed above the base, similar to an analog turntable (for example, Non-Patent Document 1). With a motorized jog dial, the user can rotate the control panel by rotating the platter and vinyl. In this case, the playback speed of the music can be changed according to the user's rotation of the platter and vinyl, allowing for scratch playback, which produces a sound similar to that of scratching an analog record.

[0003] [Non-Patent Document 1] Technics Direct Drive Digital Turntable SL-DZ1200 Manual (https: / / panasonic.jp / audio / p-db / SL-DZ1200_manualdl.html) Summary of the Invention [Problem to be solved by the invention]

[0004] However, because a motorized jog dial is driven by a motor, fluctuations in the rotation speed can occur. In such cases, if the playback speed of a song is changed according to the rotation speed of the motorized jog dial, the fluctuations will be reflected in the playback speed as well. This results in a deterioration in sound quality and also affects distortion, which is an item of audio performance. Furthermore, in DJ performances, a mix process in which multiple songs are played simultaneously is commonly performed. However, if the uneven playback speeds described above occur, it becomes difficult to accurately align the playback positions of the multiple songs being mixed, which can result in a decline in the quality of the DJ performance.

[0005] The present invention aims to solve at least part of the above problems, and one of its objectives is to provide an operating device and an audio device that can play suitable music even when unevenness occurs in the rotation speed. [Means for solving the problem]

[0006] [1] An operating device comprising: a rotary operator; a judgment unit that judges whether or not a user has touched the rotary operator; and an output unit that outputs first information indicating a playback speed that has been preset on the rotary operator when the judgment unit judges that there has been no contact; and outputs second information different from the first information when the judgment unit judges that there has been contact. [2] The operating device described in [1] further comprises a detection unit that detects the rotation speed of the rotary operator, and the determination unit determines that there is no contact when the difference between the playback speed preset in the rotary operator and the playback speed based on the rotation speed detected by the detection unit is less than a predetermined threshold.

[5] In the operating device described in [4], the determination unit determines that contact has occurred if the differences between the playback speed preset in the rotary operating member and the playback speed based on the rotation speed of the first operating member and the playback speed based on the rotation speed of the second operating member are all equal to or greater than a predetermined threshold, and determines whether or not contact has occurred with each of the first operating member and the second operating member based on the difference between the playback speed based on the rotation speed of the first operating member and the playback speed based on the rotation speed of the second operating member.

[0008] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. [Outline of the sound equipment] FIG. 1 is a schematic diagram showing the configuration of an acoustic device 100 according to this embodiment. As shown in FIG. 1, the audio device 100 according to this embodiment includes a playback device 1 and an operation device 2, and plays back music in response to user operations on the operation device 2. Each component of the acoustic device 100 will be described below.

[0009] [Playback device configuration] The playback device 1 plays music by playing music data selected by a user from among stored music data. In addition, the playback device 1 communicates with an operation device 2 and applies various sound effects to the music being played based on information output from the operation device 2. The playback device 1 can be configured, for example, by an information processing device such as a PC (Personal Computer).

[0010] [Configuration of operation device] As shown in FIG. 1, the operation device 2 includes operation units 20A and 20B provided in the player units 2A and 2B, respectively, and an operation unit 30 provided in the mixer unit 3. The operation unit 20A accepts user operations for the player unit 2A, and the operation unit 20B accepts user operations for the player unit 2B. The operation unit 30 also accepts user operations for the mixer unit 3.

[0011] The operation unit 20A includes a jog dial 21A, a tempo slider 22A, a cue button 23A, a play / pause button 24A, and a performance pad 25A.

[0012] The jog dial 21A is a circular rotary operator that functions as a rotary operator and is used to set the playback direction and playback speed of a song being played on the player unit 2 A. The jog dial 21A includes a platter unit 211A and a top panel unit 212A. The platter section 211A is a base section that is rotated by a motor (not shown) housed inside the operation device 2, similar to an analog turntable. The top panel 212A is disposed on the surface of the platter 211A, and is coaxial with the platter 211A and is rotatable relative to the platter 211A. The user can perform various DJ performances such as scratching and pitch bending by rotating at least one of the platter portion 211A and the top plate portion 212A of the jog dial 21A forward or backward, or by changing the rotation speed.

[0013] The tempo slider 22A is a lever that adjusts the playback speed of the music being played on the player section 2A. The cue button 23A is a button that is pressed when a predetermined position in a song is to be set as a cue point. The play / pause button 24A is a button that is pressed to start or stop the playback of music on the player section 2A. The performance pads 25A are general-purpose operators to which various functions relating to playback control can be assigned.

[0014] Similar to operation unit 20A, operation unit 20B includes a jog dial 21B that includes a platter portion 211B and a top panel portion 212B. Similarly to operation unit 20A, operation unit 20B also includes a tempo slider 22B, a cue button 23B, a play / pause button 24B, and a performance pad 25B.

[0015] The mixer section 3 switches the music playback between the player sections 2A and 2B, adjusts the volume of each channel, and performs playback with applied effects in accordance with user operations. The operation section 30 of the mixer section 3 includes effect selection knobs 31A and 31B, effect amount adjustment knobs 32A and 32B, channel faders 33A and 33B, and a crossfader .

[0016] The effect selection knobs 31A and 31B are used to select an effect to be applied to the music being played on the player sections 2A and 2B, respectively. The effect amount adjustment knobs 32A and 32B are used to adjust parameters such as the depth and magnitude of the effect applied to the music being played on the player sections 2A and 2B, respectively.

[0017] The channel faders 33A and 33B are levers used to adjust the output volume levels of the music being played on the player sections 2A and 2B, respectively. The crossfader 34 is a lever used to switch the output volume level of the music output from the player sections 2A and 2B. In addition to the above-described components, the operation units 20A, 20B, and 30 may further include a touch panel or the like that detects a position touched by a user.

[0018] [Configuration of operation device] 2 is a block diagram showing a schematic functional configuration of an operating device according to an embodiment. The operating device 2 includes a detection unit 4 and a control unit 5, as shown in FIG. The detection unit 4 detects input operations by the user on the operation units 20A, 20B, and 30, and supplies the detection results to the control unit 5. The control unit 5 is implemented in the operation device 2 by, for example, a communication interface, a processor such as a CPU (Central Processing Unit), and a memory that serves as a working area, and controls the operation of the operation device 2. The control unit 5 includes a determination unit 51 and an output unit 52 that are realized by the processor operating in accordance with a program stored in the memory or received via the communication interface.

[0019] The determination unit 51 performs various determinations based on the detection results from the detection unit 4. Details of the determinations will be described later. Based on the determination result by the determination unit 51, the output unit 52 outputs information based on the detection result by the detection unit 4 to the playback device 1.

[0020] 3 is a block diagram showing a schematic functional configuration of the jog dial 21A. As shown in Fig. 3, the detector 4 includes a first detector 41A and a second detector 42A corresponding to the platter 211A and the top panel 212A of the jog dial 21A, respectively. The first detection unit 41A detects the rotation speed Sr1 of the platter unit 211A, and the second detection unit 42A detects the rotation speed Sr2 of the top panel 212A. Similarly, with respect to the player unit 2B, the detection unit 4 includes a first detection unit 41B that detects the rotation speed Sr1 of the platter unit 211B, and a second detection unit 42B that detects the rotation speed Sr2 of the top panel 212B.

[0021] [Determination process by the determination unit] As described above, the determination unit 51 makes various determinations based on the detection results from the detection unit 4. Below, the determination process for determining whether or not the user has touched the jog dial 21A of the player unit 2A will be described as an example. A similar determination process for determining whether or not the user has touched the jog dial 21B of the player unit 2B is also performed. The judgment unit 51 judges whether or not the user has touched the jog dial 21A by comparing the difference between the playback speed preset on the jog dial 21A, which is a rotary operator, and the playback speed (Sp1, Sp2) based on the rotation speed (Sr1, Sr2) detected by the detection unit 4 with a predetermined threshold.

[0022] The presence or absence of the user's contact with the jog dial 21A can be classified into the following four states. (1) No contact: STATE 1 During normal playback, the jog dial 21A is rotated at a rotational speed corresponding to a preset playback speed, for example, the playback speed Sp0 set by the tempo slider 22A. When the user does not touch the jog dial 21A, the playback speed Sp1 based on the rotational speed Sr1 of the platter 211A is approximately equal to the playback speed Sp0 set by the tempo slider 22A. Similarly, the playback speed Sp2 based on the rotational speed Sr2 of the top panel 212A is also approximately equal to the playback speed Sp0 set by the tempo slider 22A. Therefore, if the difference between the playback speed Sp0 set by the tempo slider 22A and the playback speed Sp1 based on the rotation speed Sr1 of the platter portion 211A is less than a predetermined threshold, and the difference between the playback speed Sp0 set by the tempo slider 22A and the playback speed Sp2 based on the rotation speed Sr2 of the top panel portion 212A is less than a predetermined threshold, it can be determined that the user has not touched the jog dial 21A.

[0023] (2) Contact (top panel 212A only): STATE 2 When a user touches the top plate portion 212A and performs a so-called scratch operation, which rotates the top plate portion 212A forward or backward or changes the rotation speed, the playback speed Sp1 based on the rotation speed Sr1 of the platter portion 211A differs from the playback speed Sp2 based on the rotation speed Sr2 of the top plate portion 212A. Therefore, if the difference between the playback speed Sp1 based on the rotation speed Sr1 of the platter portion 211A and the playback speed Sp2 based on the rotation speed Sr2 of the top panel portion 212A is greater than or equal to a predetermined threshold, it can be determined that the user has touched the top panel portion 212A of the jog dial 21A.

[0024] (3) Contact (platter 211A only): STATE 3 When the user touches the platter 211A and performs a so-called pitch bend operation, which rotates the platter 211A forward or backward or changes the rotation speed, the playback speed Sp1 based on the rotation speed Sr1 of the platter 211A differs from the playback speed Sp0 set by the tempo slider 22A. Furthermore, the playback speed Sp1 based on the rotation speed Sr1 of the platter 211A and the playback speed Sp2 based on the rotation speed Sr2 of the top panel 212A become approximately equal. Therefore, if the difference between the playback speed Sp0 set by the tempo slider 22A and the playback speed Sp1 based on the rotation speed Sr1 of the platter portion 211A is equal to or greater than a predetermined threshold, and the difference between the playback speed Sp1 based on the rotation speed Sr1 of the platter portion 211A and the playback speed Sp2 based on the rotation speed Sr2 of the top panel portion 212A is less than a predetermined threshold, it can be determined that the user has touched only the platter portion 211A of the jog dial 21A.

[0025] (4) State transition due to other reasons: STATE 4 There may be cases where the state transition occurs for reasons other than the above-mentioned (1) to (3), such as when an operation to change the rotation speed or playback speed is performed other than via the jog dial 21A and tempo slider 22A, or when playback of a song is started or stopped using the play / pause button 24A.

[0026] [Output processing by the output unit] As described above, the output unit 52 outputs information based on the detection result by the detection unit 4 to the playback device 1, based on the determination result by the determination unit 51. Below, the output process to the playback device 1 will be described using the jog dial 21A of the player unit 2A as an example. The output process to the playback device 1 is also performed similarly for the jog dial 21B of the player unit 2B. The output unit 52 outputs appropriate information to the playback device 1 based on the four states (STATE 1 to 4) determined by the determination unit 51. Figures 4A and 4B are diagrams illustrating the output process by the output unit 52.

[0027] (1) No contact: STATE 1 If the determination unit 51 determines that the user has not touched the jog dial 21A, the output unit 52 outputs the playback speed Sp0 set by the tempo slider 22A, rather than outputting the playback speed Sp1 based on the rotation speed Sr1 of the platter unit 211A or the playback speed Sp2 based on the rotation speed Sr2 of the top panel 212A. This is a process to prevent unevenness in the rotation speed that occurs in the jog dial 21A, which is a motorized jog dial, from being reflected in the playback speed Sp1 based on the rotation speed Sr1 of the platter unit 211A and the playback speed Sp2 based on the rotation speed Sr2 of the top panel 212A.

[0028] Generally, a motorized jog dial performs playback processing based on a playback speed Sp1 based on the rotation speed Sr1 of the platter portion 211A and a playback speed Sp2 based on the rotation speed Sr2 of the top panel portion 212A. In contrast, in this embodiment, if the determination unit 51 determines that the user has not touched the jog dial 21A, the output unit 52 of the operation device 2 outputs information based on the tempo slider 22A, as shown in Fig. 4A. Then, the playback device 1 performs playback processing in accordance with the information based on the tempo slider 22A. As a result, it is possible to prevent unevenness in the rotation speed of the jog dial 21A, which is a motorized jog dial, from deteriorating the sound quality of the music being played and affecting the distortion rate, which is an item of audio performance. The information output by the output unit 52 may include information indicating that "the user has not touched the jog dial 21A."

[0029] (2) Contact (top panel 212A only): STATE 2 When the judgment unit 51 determines that the user has touched the top panel portion 212A of the jog dial 21A, the output unit 52 outputs a playback speed Sp1 based on the rotation speed Sr1 of the platter portion 211A and a playback speed Sp2 based on the rotation speed Sr2 of the top panel portion 212A. That is, when the determination unit 51 determines that the user has touched the top panel 212A of the jog dial 21A, the output unit 52 of the operation device 2 outputs information based on the jog dial 21A, as shown in Fig. 4B. Then, the playback device 1 performs playback processing in accordance with the information based on the jog dial 21A. As a result, when the determination unit 51 determines that the user has touched the top panel 212A of the jog dial 21A, scratch playback processing and the like can be performed based on the information actually detected on the jog dial 21A. The information output by the output unit 52 is not limited to the playback speed, but may also include the rotation speed, rotation angle, rotation direction, etc. Also, it may include information indicating that "the user has touched the top panel portion 212A of the jog dial 21A."

[0030] (3) Contact (platter 211A only): STATE 3 When the determining unit 51 determines that the user has touched the platter unit 211A of the jog dial 21A, the output unit 52 outputs the playback speed Sp1 based on at least the rotation speed Sr1 of the platter unit 211A. That is, when the determination unit 51 determines that the user has touched the platter portion 211A of the jog dial 21A, the output unit 52 of the operation device 2 outputs information based on the jog dial 21A, as in (2) above, as shown in FIG. 4B. Then, the playback device 1 performs playback processing in accordance with the information based on the jog dial 21A. As a result, when the determination unit 51 determines that the user has touched the platter portion 211A of the jog dial 21A, pitch bend playback processing and the like can be performed based on the information actually detected on the jog dial 21A. If the determination unit 51 determines that the user has touched the platter portion 211A of the jog dial 21A, the output unit 52 may output a playback speed Sp2 based on the rotation speed Sr2 of the top panel 212A, in addition to the playback speed Sp1 based on the rotation speed Sr1 of the platter portion 211A. The information output by the output unit 52 is not limited to the playback speed, and may include the rotation speed, rotation angle, rotation direction, etc. The information may also include information indicating that "the user has touched the top panel 212A of the jog dial 21A."

[0031] (4) State transition due to other reasons: STATE 4 If the determination unit 51 determines that a state transition has occurred due to a reason other than (1) to (3), the output unit 52 outputs corresponding information. For example, if an operation to start or stop playback of a song is performed using the play / pause button 24A, the output unit 52 outputs information indicating the operation.

[0032] [Information output processing based on judgment processing] 5 is a flowchart showing the processing executed by the control unit 5. The following description will be given taking the jog dial 21A of the player unit 2A as an example. The same processing is also carried out for the jog dial 21B of the player unit 2B.

[0033] The determination unit 51 acquires information based on the tempo slider 22A from the detection unit 4 (step S101). Next, the determination unit 51 acquires information indicating the rotation speed Sr1 of the platter unit 211A from the first detection unit 41A of the detection unit 4, and calculates a playback speed Sp1 based on the rotation speed Sr1 (step S102).The determination unit 51 also acquires information indicating the rotation speed Sr2 of the top panel unit 212A from the second detection unit 42A of the detection unit 4, and calculates a playback speed Sp2 based on the rotation speed Sr2 (step S103). Thereafter, the determination unit 51 determines whether or not there is another state transition other than the operation on the jog dial 21A and the tempo slider 22A (step S104). If it is determined in the determination process of step S104 that there is a state transition (step S104: NO), the control unit 5 proceeds to step S110, which will be described later.

[0034] If the judgment unit 51 judges in the judgment process of step S104 that there is no state transition (step S104: YES), the judgment unit 51 judges whether the difference between the playback speed Sp1 based on the rotation speed Sr1 of the platter unit 211A and the playback speed Sp2 based on the rotation speed Sr2 of the top panel unit 212A is less than a predetermined threshold value Th1 (step S105). If it is determined in the determination process of step S105 that the difference is equal to or greater than the predetermined threshold value Th1 (step S105: NO), the control unit 5 proceeds to step S108, which will be described later.

[0035] If the judgment process of step S105 determines that the difference is less than a predetermined threshold value Th1 (step S105: YES), the judgment unit 51 determines whether the difference between the playback speed Sp0 set by the tempo slider 22A and the playback speed Sp1 based on the rotation speed Sr1 of the platter unit 211A is less than a predetermined threshold value Th2 (step S106). In the judgment process of step S106, if it is determined that the difference between the playback speed Sp0 set by the tempo slider 22A and the playback speed Sp1 based on the rotation speed Sr1 of the platter unit 211A is equal to or greater than a predetermined threshold value Th2 (step S106: NO), the control unit 5 proceeds to step S109, which will be described later.

[0036] If it is determined in the determination process of step S106 that the difference between the playback speed Sp0 set by the tempo slider 22A and the playback speed Sp1 based on the rotation speed Sr1 of the platter unit 211A is less than the predetermined threshold value Th2 (step S106: YES), the playback speed Sp0 set by the tempo slider 22A, the playback speed Sp1 based on the rotation speed Sr1 of the platter unit 211A, and the playback speed Sp2 based on the rotation speed Sr2 of the top panel 212A are approximately equal, and therefore the determination unit 51 determines that the state of whether the user is touching the jog dial 21A is STATE 1 (step S107).

[0037] If it is determined in the determination process of step S105 that the difference is equal to or greater than the predetermined threshold value Th1 (step S105: NO), the playback speed Sp1 based on the rotation speed Sr1 of the platter unit 211A and the playback speed Sp2 based on the rotation speed Sr2 of the top panel unit 212A are different, and therefore the determination unit 51 determines that the state of whether or not the user is touching the jog dial 21A is STATE 2 (step S108). Furthermore, if it is determined in the determination process of step S106 that the difference between the playback speed Sp0 set by the tempo slider 22A and the playback speed Sp1 based on the rotation speed Sr1 of the platter unit 211A is equal to or greater than a predetermined threshold value Th2 (step S106: NO), the determination unit 51 determines that the state of whether the user has touched the jog dial 21A is STATE 3 (step S109), because the playback speed Sp0 set by the tempo slider 22A and the playback speed Sp1 based on the rotation speed Sr1 of the platter unit 211A are different and the playback speed Sp1 based on the rotation speed Sr1 of the platter unit 211A and the playback speed Sp2 based on the rotation speed Sr2 of the top panel 212A are approximately equal. Furthermore, if it is determined in the determination process of step S104 that there is a state transition (step S104: NO), the control unit 5 determines that the state of whether or not the user is touching the jog dial 21A is STATE 4 (step S110).

[0038] The output unit 52 outputs information to the playback device 1 based on the state of whether or not the user is touching the jog dial 21A, which is determined in any one of steps S107 to S110 (step S111). The series of processes is repeatedly executed until a predetermined ending operation is performed, such as turning off the power of the controller device 2, for example.

[0039] [Effects of the embodiment] The operating device 2 according to the present embodiment described above can achieve the following effects. The device includes jog dials 21A and 21B which are rotary operators, a determination unit 51 which determines whether or not the user has touched the jog dials 21A and 21B, and an output unit 52 which outputs first information indicating a playback speed set in advance to the jog dials 21A and 21B when the determination unit 51 determines that there has been no touch, and outputs second information different from the first information when the determination unit 51 determines that there has been contact. With this configuration, even if the rotation speed of the motorized jog dials 21A and 21B varies, it is possible to output information for optimal music playback. This prevents problems such as a deterioration in sound quality and an impact on distortion, which is an audio performance item, and also prevents problems such as a decrease in the quality of the DJ performance due to difficulty in accurately aligning the playback position between multiple songs being mixed during DJ performance.

[0040] Furthermore, the operation device 2 according to this embodiment further includes a detection unit 4 that detects the rotation speeds of the jog dials 21A and 21B. The determination unit 51 determines that no contact has occurred when the difference between the playback speed preset for the jog dials 21A and 21B and the playback speed based on the rotation speed detected by the detection unit 4 is less than a predetermined threshold. The determination unit 51 then determines that contact has occurred when the difference is equal to or greater than the predetermined threshold. When the determination unit 51 determines that contact has occurred, the output unit 52 outputs, as second information, information indicating the playback speed based on the rotation speed detected by the detection unit 4. Therefore, it is possible to determine whether or not the user has touched the jog dials 21A and 21B without providing a special sensor for detecting contact. Furthermore, it is possible to output information for playing suitable music depending on whether or not the user has touched the jog dials 21A and 21B.

[0041] Furthermore, according to the operation device 2 of this embodiment, the jog dials 21A, 21B include platter units 211A, 211B, which are first operation members that are rotationally driven by a motor, and top panel units 212A, 212B, which are second operation members that are coaxial with the platter units 211A, 211B and can rotate relative to the platter units 211A, 211B. The detection unit 4 includes first detection units 41A, 41B that detect the rotation speed of the platter units 211A, 211B, and second detection units 42A, 42B that detect the rotation speed of the top panel units 212A, 212B. The determination unit 51 determines that there is no contact if the differences between the playback speeds (Sp1, Sp2) based on the rotation speeds (Sr1, Sr2) of the platter units 211A, 211B and the top panel units 212A, 212B detected by the first detection units 41A, 41B and the playback speed Sp0 preset in the jog dials 21A, 21B are all less than a predetermined threshold.The determination unit 51 also determines that there is contact if the differences between the playback speed Sp0 preset in the jog dials 21A, 21B and the playback speed Sp1 based on the rotation speed Sr1 of the platter units 211A, 211B and the playback speed Sp2 based on the rotation speed Sr2 of the top panel units 212A, 212B are all equal to or greater than a predetermined threshold. In addition, the judgment unit 51 judges whether or not there is contact between the platter units 211A, 211B and the top panel units 212A, 212B based on the difference between the playback speed Sp1 based on the rotation speed Sr1 of the platter units 211A, 211B and the playback speed Sp2 based on the rotation speed Sr2 of the top panel units 212A, 212B. Therefore, it is possible to individually determine whether or not there is contact with each of platter sections 211A, 211B and top panel sections 212A, 212B. Furthermore, it is possible to output information for playing suitable music depending on whether or not there is contact with each of platter sections 211A, 211B and top panel sections 212A, 212B.

[0042] Furthermore, the acoustic device 100 according to this embodiment includes the above-described operation device 2 and a playback device 1 that plays back music data, and the output unit 52 outputs at least one of the first information and the second information to the playback device 1. Therefore, the playback device 1 can achieve optimal playback of music based on the information output from the operation device 2.

[0043] [Modification of the embodiment] The present invention is not limited to the above-described embodiment, and modifications and improvements within the scope of achieving the object of the present invention are included in the present invention. In the above embodiment, the detection unit 4 detects the rotation speed of the jog dials 21A, 21B, and the judgment unit 51 judges whether or not the user has touched the jog dials 21A, 21B based on the detection result by the detection unit 4, but the present invention is not limited to this example. The detection unit 4 may be configured to include, for example, a touch sensor that detects whether or not the user has touched the jog dials 21A, 21B, and determine whether or not the user has touched the jog dials 21A, 21B based on the output of the touch sensor. Note that the touch sensor may be provided on each of the platter units 211A, 211B and top panel units 212A, 212B that constitute the jog dials 21A, 21B, and configured to detect the rotation speeds individually. The touch sensor may be a type that detects pressure, or may be a capacitance type or other type that can detect user operations, and any sensing method is acceptable. The detection result of the rotation speed of the jog dials 21A, 21B described in this embodiment may be combined with the detection result of the touch sensor to determine whether the jog dials 21A, 21B are touched by the user.

[0044] In the above embodiment, an example was shown in which the jog dials 21A, 21B include platter portions 211A, 211B and top plate portions 212A, 212B, and the top plate portions 212A, 212B are rotatable relative to the platter portions 211A, 211B, but the present invention is not limited to this example. The jog dials 21A, 21B may be configured so that members corresponding to the platter portions 211A, 211B and the top panel portions 212A, 212B rotate integrally. In such a case, the detection unit 4 detects the rotation speed of the entire jog dials 21A, 21B, and the determination unit 51 determines that the user has not touched the jog dials 21A, 21B if the difference between the playback speed preset for the jog dials 21A, 21B and the playback speed based on the rotation speed of the entire jog dials 21A, 21B detected by the detection unit 4 is less than a predetermined threshold, and determines that the user has touched the jog dials 21A, 21B if the difference is equal to or greater than the predetermined threshold.

[0045] Furthermore, the operating device of the present invention is not limited to one that outputs information to the playback device 1 that plays back music data, and may be configured to output information to other devices and equipment. Furthermore, the present invention can also be applied to a DJ system that integrates multiple players that play music and a mixer that controls the players. Furthermore, in each of the above embodiments, a two-channel operation device having two player sections 2A and 2B has been described, but similar functions can also be realized with, for example, a four-channel operation device.
