　本発明は、検出装置、音響装置、回転情報算出方法、及び回転情報算出プログラムに関する。 The present invention relates to a detection device, an acoustic device, a rotation information calculation method, and a rotation information calculation program.
　従来、ジョグダイヤルなどの回転操作子の回転操作を検出して音楽を再生する装置が知られている（例えば、特許文献１参照）。
　特許文献１に記載の光ディスク再生装置では、ジョグダイヤルよりも大径のシャッター部をジョグダイヤルに設けるとともに、シャッター部にフォトインタラプタを組み合わせ、フォトインタラプタから出力される制御パルスに基づいてジョグダイヤルの回転操作を検出している。 Conventionally, a device that detects a rotation operation of a rotation controller such as a jog dial and reproduces music is known (see, for example, Patent Document 1).

The rotation information may be calculated by any method. For example, the rotation information calculation unit 53B extracts the feature points in the surface state based on the acquired output signal, and the movement amount and the movement direction of the feature points. By obtaining the above, the rotation speed and the rotation direction of the disk 43, and by extension, the rotation angle and the rotation direction of the jog dial 4 are calculated.
　情報送信部５３Ｃは、回転情報算出部５３Ｂによって算出された回転情報を情報処理装置Ｄに送信する。情報処理装置Ｄは、受信した回転情報に基づいて楽曲データの再生状態を制御し、楽曲データを再生して得られる楽曲信号をミキサーＭに出力する。すなわち、回転情報算出部５３Ｂによって算出された回転情報は、情報処理装置Ｄが有する再生部による楽曲データの再生制御に利用される。 The information transmission unit 53C transmits the rotation information calculated by the rotation information calculation unit 53B to the information processing device D. The information processing apparatus D controls the reproduction state of the music data based on the received rotation information, and outputs the music signal obtained by reproducing the music data to the mixer M. That is, the rotation information calculated by the rotation information calculation unit 53B is used for the reproduction control of the music data by the reproduction unit possessed by the information processing apparatus D.

　制御部５３は、上記構成により図４に示す回転情報の算出処理を実行することによって、ジョグダイヤル４に関する回転情報を算出する。回転情報の算出処理は、図示しない記憶部に記憶された回転情報算出プログラムを制御部５３が実行することにより行われる。 [Calculation processing of rotation information according to the operation for the jog dial]
FIG. 4 is a flowchart showing a rotation information calculation process executed by the control unit 53.
The control unit 53 calculates the rotation information related to the jog dial 4 by executing the rotation information calculation process shown in FIG. 4 according to the above configuration. The rotation information calculation process is performed by the control unit 53 executing a rotation information calculation program stored in a storage unit (not shown).
　回転情報の算出処理では、まず、信号取得部５３Ａが、検出装置５のイメージセンサー５１による円盤４３の表面状態を示す出力信号を取得する（ステップＳ１１）。
　次に、回転情報算出部５３Ｂが、取得された出力信号に基づいて、ジョグダイヤル４の回転角度と回転方向とを含む回転情報を算出する（ステップＳ１２）。
　この後、情報送信部５３Ｃが、算出された回転情報を送信する（ステップＳ１３）。
　このような制御部５３によるステップＳ１１からステップＳ１３の処理は、例えば操作装置１の電源がオフされる等の所定の終了操作が行われるまで、繰り返し実行される。 In the rotation information calculation process, first, the signal acquisition unit 53A acquires an output signal indicating the surface state of the disk 43 by the image sensor 51 of the detection device 5 (step S11).
Next, the rotation information calculation unit 53B calculates rotation information including the rotation angle and the rotation direction of the jog dial 4 based on the acquired output signal (step S12).
After that, the information transmission unit 53C transmits the calculated rotation information (step S13).
The processes of steps S11 to S13 by the control unit 53 are repeatedly executed until a predetermined end operation such as turning off the power of the operating device 1 is performed.
　［第１実施形態の効果］
　以上説明した本実施形態に係る操作装置１によれば、以下の効果を奏することができる。
　操作装置１の検出装置５は、第１検出部であるイメージセンサー５１と、照射部５２と、回転情報算出部５３Ｂと、を備える。照射部５２は、回転操作子であるジョグダイヤル４の円盤４３に光を照射し、イメージセンサー５１は、円盤４３にて反射された光を検出する。円盤４３は、被検出部に相当する。回転情報算出部５３Ｂは、イメージセンサー５１の出力信号によって示される円盤４３の表面状態の経時変化に基づいて、ジョグダイヤル４の回転角度及びジョグダイヤル４の回転方向を含む回転情報を算出する。
　このような構成によれば、従来のフォトインタラプタを用いた検出のように、回転操作子の検出が不可能な状態、および、検出が遅延する状態が発生することを抑制できる。この他、回転操作子であるジョグダイヤル４の回転操作の検出精度を高めることができる。
　特に、上述した構成によれば、円盤４３の表面の微細な表面変化をとらえることにより、フォトインタラプタを用いた検出と比較して高速な検出が可能である。そのため、操作装置１から送信される回転情報に基づく楽曲データの再生処理、および楽曲データに様々な効果を付与する処理の反応速度を高めることができる。また、解像度に換算すると、フォトインタラプタを用いた検出と比較して、１０から１００倍程度、解像度を高めることができる。したがって、非常にゆっくりしたユーザーの操作、及び微細なユーザーの操作についても、正確、精細、かつ低遅延な検出を実現することが可能であり、検出精度を高めることができる。 [Effect of the first embodiment]
According to the operation device 1 according to the present embodiment described above, the following effects can be obtained.
The detection device 5 of the operation device 1 includes an image sensor 51 which is a first detection unit, an irradiation unit 52, and a rotation information calculation unit 53B. The irradiation unit 52 irradiates the disk 43 of the jog dial 4, which is a rotation controller, with light, and the image sensor 51 detects the light reflected by the disk 43. The disk 43 corresponds to the detected portion. The rotation information calculation unit 53B calculates rotation information including the rotation angle of the jog dial 4 and the rotation direction of the jog dial 4 based on the time course of the surface state of the disk 43 indicated by the output signal of the image sensor 51.
According to such a configuration, it is possible to suppress the occurrence of a state in which the rotation operator cannot be detected and a state in which the detection is delayed, as in the case of detection using the conventional photo interrupter. In addition, the detection accuracy of the rotation operation of the jog dial 4 which is the rotation controller can be improved.
In particular, according to the above-described configuration, by capturing minute surface changes on the surface of the disk 43, high-speed detection is possible as compared with detection using a photo interrupter. Therefore, it is possible to increase the reaction speed of the music data reproduction processing based on the rotation information transmitted from the operation device 1 and the processing of imparting various effects to the music data. Further, in terms of resolution, the resolution can be increased by about 10 to 100 times as compared with the detection using the photo interrupter. Therefore, it is possible to realize accurate, fine, and low-delay detection even for a very slow user operation and a fine user operation, and it is possible to improve the detection accuracy.
　イメージセンサー５１は、被検出部として、回転軸Ｒｘに直交する面を有し、かつ、回転軸Ｒｘを中心として回転体４１とともに回転する円盤４３からの光を検出する。円盤４３は、板状体に相当する。
　このような構成によれば、イメージセンサー５１によって、円盤４３を介して回転体４１の回転を精度よく検出できる。 The image sensor 51 has a surface orthogonal to the rotation axis Rx as a detected portion, and detects light from a disk 43 rotating together with the rotating body 41 about the rotation axis Rx. The disk 43 corresponds to a plate-like body.
According to such a configuration, the image sensor 51 can accurately detect the rotation of the rotating body 41 via the disk 43.
　なお、第１実施形態では、被検出部として円盤４３を用いる例を示したが、円盤４３に代えて、または加えて、回転操作子であるジョグダイヤル４の回転軸を被検出部としてもよい。また、被検出部は、円形状の板状体である円盤４３でなくてもよく、多角形状の板状体であってもよい。 Although the example in which the disk 43 is used as the detected unit is shown in the first embodiment, the rotation axis of the jog dial 4, which is a rotation operator, may be used as the detected unit in place of or in addition to the disk 43. Further, the detected portion does not have to be the disk 43 which is a circular plate-shaped body, and may be a polygonal plate-shaped body.
　＜第２実施形態＞

　複数のスリット６１Ｓのそれぞれは、後述する発光部７２Ａから受光部７２Ｂに入射される光を通過させる開口部である。
　複数の遮光部６１Ｐのそれぞれは、発光部７２Ａから受光部７２Ｂに入射される光を遮蔽する。
　回転軸Ｒｘを中心とする周方向において、各スリット６１Ｓの幅は同じであり、各遮光部６１Ｐの幅は同じである。また、当該周方向において、スリット６１Ｓの幅と遮光部６１Ｐの幅とは同じである。 [Configuration of operating equipment]
FIG. 5 is a schematic view showing the internal configuration of the jog dial 6 of the second embodiment.
The operation device according to the present embodiment has the same configuration and function as the operation device 1 according to the first embodiment, except that the jog dial 6 and the detection device 7 shown in FIG. 5 are provided in place of the jog dial 4 and the detection device 5. Have.
The jog dial 6 has the same configuration and function as the jog dial 4 except that it has a disk 61 as a plate-like body instead of the disk 43.
As shown in FIG. 5, the disk 61 has a plurality of slits 61S provided at equal intervals along the circumferential direction about the rotation axis Rx of the jog dial 6 and a light-shielding portion provided between the plurality of slits 61S. It has 61P and.
Each of the plurality of slits 61S is an opening through which light incident on the light receiving unit 72B from the light emitting unit 72A described later passes.
Each of the plurality of light-shielding units 61P shields the light incident on the light-receiving unit 72B from the light-emitting unit 72A.
The width of each slit 61S is the same in the circumferential direction about the rotation axis Rx, and the width of each light-shielding portion 61P is the same. Further, in the circumferential direction, the width of the slit 61S and the width of the light-shielding portion 61P are the same.
　［検出装置の構成］
　図６は、第２実施形態のジョグダイヤル６の内部構成を示す別の模式図である。
　検出装置７は、制御部５３に代えて制御部７１（図７参照）を備えるとともに、図５及び図６に示すように、フォトインタラプタ７２をさらに有する他は、検出装置５と同様の構成を有する。 [Detector configuration]
FIG. 6 is another schematic view showing the internal configuration of the jog dial 6 of the second embodiment.
The detection device 7 has the same configuration as the detection device 5 except that the control unit 71 (see FIG. 7) is provided in place of the control unit 53 and, as shown in FIGS. 5 and 6, the detection device 7 further includes a photo interrupter 72. Have.
　［フォトインタラプタの構成］
　フォトインタラプタ７２は、図５及び図６に示すように、円盤６１に対して１つのスリット６１Ｓ又は１つの遮光部６１Ｐに応じた位置で、かつ、イメージセンサー５１と重ならない位置に配置される。すなわち、イメージセンサー５１は、イメージセンサー５１が円盤６１の表面のうち、スリット６１Ｓ及び遮光部６１Ｐを除く部分からの光を検出可能な位置に設けられる。 [Structure of photo interrupter]
As shown in FIGS. 5 and 6, the photo interrupter 72 is arranged at a position corresponding to one slit 61S or one light-shielding portion 61P with respect to the disk 61 and at a position not overlapping with the image sensor 51. That is, the image sensor 51 is provided at a position where the image sensor 51 can detect light from a portion of the surface of the disk 61 excluding the slit 61S and the light-shielding portion 61P.
　フォトインタラプタ７２は、発光部７２Ａと、発光部７２Ａから出射された光を受光する受光部７２Ｂと、を備え、受光部７２Ｂによる光の検出結果（受光結果）を示す信号を出力する。
　発光部７２Ａは、円盤６１に対して光を出射する。
　受光部７２Ｂは、円盤６１の複数のスリット６１Ｓを通過した光を受光し、受光結果をパルス信号として出力する。
　ここで、ジョグダイヤル６に対する回転操作が行われると、円盤６１が回転軸Ｒｘを中心として回転され、発光部７２Ａによる光の出射位置にスリット６１Ｓ及び遮光部６１Ｐのうち一方が配置される。光の出射位置にスリット６１Ｓが位置する場合には、発光部７２Ａから出射された光は、スリット６１Ｓを介して受光部７２Ｂに入射される。一方、光の出射位置に遮光部６１Ｐが位置する場合には、発光部７２Ａから出射された光は、遮光部６１Ｐにて遮蔽され、受光部７２Ｂにより受光されない。受光部７２Ｂは、受光結果を示す信号として、スリット６１Ｓを通過した光を検出しているときに例えばハイレベルの信号を出力し、光を検出していないときに例えばローレベルの信号を出力する。
　なお、フォトインタラプタ７２については、公知のものと同様に構成できるため、詳細な説明を省略する。また、フォトインタラプタ７２の発光部７２Ａは、照明光の光源としては、ＬＥＤ光源、レーザー光源等を利用することが可能である。また、照明光の波長については、赤外光等各種波長の光を利用することが可能である。 The photointerruptor 72 includes a light emitting unit 72A and a light receiving unit 72B that receives light emitted from the light emitting unit 72A, and outputs a signal indicating a light detection result (light receiving result) by the light receiving unit 72B.
The light emitting unit 72A emits light to the disk 61.
The light receiving unit 72B receives light that has passed through the plurality of slits 61S of the disk 61, and outputs the light receiving result as a pulse signal.
Here, when the rotation operation with respect to the jog dial 6 is performed, the disk 61 is rotated about the rotation axis Rx, and one of the slit 61S and the light-shielding portion 61P is arranged at the light emitting position by the light emitting unit 72A. When the slit 61S is located at the light emitting position, the light emitted from the light emitting unit 72A is incident on the light receiving unit 72B through the slit 61S. On the other hand, when the light emitting unit 61P is located at the light emitting position, the light emitted from the light emitting unit 72A is shielded by the light emitting unit 61P and is not received by the light receiving unit 72B. The light receiving unit 72B outputs, for example, a high-level signal when the light passing through the slit 61S is detected, and outputs, for example, a low-level signal when the light is not detected, as a signal indicating the light receiving result. ..
Since the photo interrupter 72 can be configured in the same manner as a known one, detailed description thereof will be omitted. Further, the light emitting unit 72A of the photo interrupter 72 can use an LED light source, a laser light source, or the like as a light source of the illumination light. Further, as the wavelength of the illumination light, it is possible to use light of various wavelengths such as infrared light.
　本実施形態では、フォトインタラプタ７２は、上述した発光部７２Ａ及び受光部７２Ｂの組を２つ備え、２組の発光部７２Ａ及び受光部７２Ｂが、１つのパッケージ内に組み込まれている。２組の発光部７２Ａ及び受光部７２Ｂは、例えばスリット６１Ｓの幅の１／４の距離だけ、回転軸Ｒｘを中心とする周方向に互いにずれて配置される。そのため、ジョグダイヤル６が回転されたときに、２つの受光部７２Ｂのうち一方の受光部７２Ｂから出力されるパルス信号の位相と、他方の受光部７２Ｂから出力されるパルス信号の位相とは、互いに１／４ずれている。
　このようなフォトインタラプタ７２から出力されるパルス信号は、制御部７１による回転情報の算出に用いられる。回転情報の算出については後述する。 In the present embodiment, the photointerruptor 72 includes two sets of the light emitting unit 72A and the light receiving unit 72B described above, and the two sets of the light emitting unit 72A and the light receiving unit 72B are incorporated in one package. The two sets of the light emitting unit 72A and the light receiving unit 72B are arranged so as to be offset from each other in the circumferential direction about the rotation axis Rx by, for example, a distance of 1/4 of the width of the slit 61S. Therefore, when the jog dial 6 is rotated, the phase of the pulse signal output from one of the two light receiving units 72B and the phase of the pulse signal output from the other light receiving unit 72B are mutually exclusive. It is off by 1/4.
The pulse signal output from such a photointerruptor 72 is used for calculation of rotation information by the control unit 71. The calculation of rotation information will be described later.
　［制御部の機能構成］
　図７は、制御部７１の機能構成を示すブロック図である。
　制御部７１は、図７に示すように、情報取得部７１Ａ、回転速度算出部７１Ｂ、モード切替部７１Ｃ、回転情報算出部７１Ｄ、誤差補正部７１Ｅ及び情報送信部７１Ｆを有する。 [Functional configuration of control unit]
FIG. 7 is a block diagram showing a functional configuration of the control unit 71.
As shown in FIG. 7, the control unit 71 includes an information acquisition unit 71A, a rotation speed calculation unit 71B, a mode switching unit 71C, a rotation information calculation unit 71D, an error correction unit 71E, and an information transmission unit 71F.
　情報取得部７１Ａは、第１実施形態で説明した信号取得部５３Ａと同様に、イメージセンサー５１による円盤６１の表面状態を示す出力信号を取得する。更に、情報取得部７１Ａは、フォトインタラプタ７２から出力されたパルス信号を取得する。
　回転速度算出部７１Ｂは、少なくともイメージセンサー５１の出力信号に基づいて、ジョグダイヤル６の回転速度を算出する。回転速度の算出は、例えば、回転情報算出部５３Ｂによる回転速度の算出と同様の手法によって実施可能である。 The information acquisition unit 71A acquires an output signal indicating the surface state of the disk 61 by the image sensor 51, similarly to the signal acquisition unit 53A described in the first embodiment. Further, the information acquisition unit 71A acquires the pulse signal output from the photointerruptor 72.
The rotation speed calculation unit 71B calculates the rotation speed of the jog dial 6 at least based on the output signal of the image sensor 51. The calculation of the rotation speed can be performed by, for example, the same method as the calculation of the rotation speed by the rotation information calculation unit 53B.
　モード切替部７１Ｃは、回転速度算出部７１Ｂが算出した回転速度に応じて、回転情報算出部７１Ｄによる動作モードを第１モードまたは第２モードに切り替える。
　第１モードは、イメージセンサー５１の出力信号に基づいて回転情報を算出する動作モードであり、第２モードは、フォトインタラプタ７２から出力されたパルス信号に基づいて回転情報を算出する動作モードである。
　第１実施形態で説明したように、イメージセンサー５１の出力信号に基づいた回転情報の算出には、解像度の向上、超低速なユーザーの操作への対応、微細なユーザーの操作への対応、検出の低遅延化等の利点がある。しかし、回転検出処理の特性上、比較的高速なジョグダイヤル６の回転に追随しづらい他、誤差が累積するという問題がある。一方、フォトインタラプタ７２は、比較的高速なジョグダイヤル６の回転に追随しやすいが、ジョグダイヤル６が低速に回転される場合には回転の検出が遅延したり、微細な回転を検出しづらい。 The mode switching unit 71C switches the operation mode by the rotation information calculation unit 71D to the first mode or the second mode according to the rotation speed calculated by the rotation speed calculation unit 71B.
The first mode is an operation mode for calculating rotation information based on the output signal of the image sensor 51, and the second mode is an operation mode for calculating rotation information based on the pulse signal output from the photointerruptor 72. ..
As described in the first embodiment, in the calculation of the rotation information based on the output signal of the image sensor 51, the resolution is improved, the ultra-low speed user operation is supported, the minute user operation is supported, and the detection is performed. There are advantages such as low delay. However, due to the characteristics of the rotation detection process, it is difficult to follow the rotation of the jog dial 6 at a relatively high speed, and there is a problem that errors are accumulated. On the other hand, the photo interrupter 72 tends to follow the rotation of the jog dial 6 at a relatively high speed, but when the jog dial 6 is rotated at a low speed, the detection of rotation is delayed or it is difficult to detect minute rotation.
　これに対し、モード切替部７１Ｃは、検出装置７の動作モードを、イメージセンサー５１の出力信号に基づいて回転情報を算出する第１モードと、フォトインタラプタ７２から出力されたパルス信号に基づいて回転情報を算出する第２モードとのうち一方に切り替える。
　具体的に、検出装置７の切替モードが手動切替モードである場合、モード切替部７１Ｃは、操作部３に対するユーザーの操作に応じて、動作モードを第１モードと第２モードとのうち一方に切り替える。
　また、検出装置７の切替モードが自動切替モードである場合、モード切替部７１Ｃは、算出された回転速度が所定の速度未満である場合には、第１モードに動作モードを切り替え、算出された回転速度が上述した所定の速度以上である場合には、第２モードに動作モードを切り替える。すなわち、モード切替部７１Ｃは、手動モード切替部の機能と自動モード切替部の機能とを有する。
　なお、手動切替モードと自動切替モードとの切替は、ユーザーが操作部３を操作することによって実施されてもよい。また、閾値となる所定の速度は、予め定められてもよいし、ユーザーにより設定可能としてもよい。さらに、再生対象の楽曲データの特性等の条件に応じて閾値を決定する構成としてもよい。 On the other hand, the mode switching unit 71C rotates the operation mode of the detection device 7 based on the first mode for calculating the rotation information based on the output signal of the image sensor 51 and the pulse signal output from the photo interrupter 72. Switch to one of the second modes for calculating information.
Specifically, when the switching mode of the detection device 7 is the manual switching mode, the mode switching unit 71C sets the operation mode to one of the first mode and the second mode according to the user's operation on the operation unit 3. Switch.
Further, when the switching mode of the detection device 7 is the automatic switching mode, the mode switching unit 71C switches the operation mode to the first mode when the calculated rotation speed is less than the predetermined speed, and is calculated. When the rotation speed is equal to or higher than the above-mentioned predetermined speed, the operation mode is switched to the second mode. That is, the mode switching unit 71C has a function of a manual mode switching unit and a function of an automatic mode switching unit.
The switching between the manual switching mode and the automatic switching mode may be performed by the user operating the operation unit 3. Further, a predetermined speed as a threshold value may be predetermined or may be set by the user. Further, the threshold value may be determined according to conditions such as the characteristics of the music data to be reproduced.
　動作モードが第１モードである場合、回転情報算出部７１Ｄは、第１実施形態で説明した回転情報算出部５３Ｂと同様に、情報取得部７１Ａによって取得された出力信号を解析し、ジョグダイヤル６の回転情報を算出する。なお、この回転情報の算出は、上述した回転速度算出部７１Ｂによる回転速度の算出と合わせて行われてもよい。
　動作モードが第２モードである場合、回転情報算出部７１Ｄは、フォトインタラプタ７２から出力されたパルス信号に基づいて、ジョグダイヤル６の回転情報を算出する。より具体的には、回転情報算出部７１Ｄは、一定時間内のパルス数をカウントすることにより回転角度を算出し、互いに位相が異なるパルス信号を比較することにより回転方向を算出する。フォトインタラプタを用いた回転情報の算出については、例えば、特開２００３－２４９０６４号公報と同様に行うことができる。 When the operation mode is the first mode, the rotation information calculation unit 71D analyzes the output signal acquired by the information acquisition unit 71A and analyzes the output signal acquired by the information acquisition unit 71A, similarly to the rotation information calculation unit 53B described in the first embodiment, and the jog dial 6 is used. Calculate rotation information. The calculation of the rotation information may be performed together with the calculation of the rotation speed by the rotation speed calculation unit 71B described above.
When the operation mode is the second mode, the rotation information calculation unit 71D calculates the rotation information of the jog dial 6 based on the pulse signal output from the photointerruptor 72. More specifically, the rotation information calculation unit 71D calculates the rotation angle by counting the number of pulses within a certain period of time, and calculates the rotation direction by comparing pulse signals having different phases from each other. The calculation of the rotation information using the photo interrupter can be performed, for example, in the same manner as in Japanese Patent Application Laid-Open No. 2003-249064.
　図８Ａ及び図８Ｂは、第２モードでの回転情報算出部７１Ｄによる回転情報の算出処理について説明する模式図である。
　動作モードが第２モードである場合、回転情報算出部７１Ｄは、図８Ａに示すように、情報取得部７１Ａから取得される、互いに位相が異なる２つのパルス信号Ｐ１、Ｐ２に基づいて回転情報を算出する。
　フォトインタラプタ７２は、上述したように、受光部７２Ｂがスリット６１Ｓを通過した光を検出しているときに例えばハイレベルの信号を出力し、光を検出していないときに例えばローレベルの信号を出力する。しかしながら、発光部７２Ａから出射された光が１つのスリット６１Ｓの中に留まるようなジョグダイヤル６の回転操作、及び、当該光が２つのスリット６１Ｓ間の遮光部６１Ｐに留まるようなジョグダイヤル６の回転操作が行われた場合には、フォトインタラプタ７２から出力されるパルス信号は、ハイレベル又はローレベルのままとなる。この場合、フォトインタラプタ７２から出力される信号に基づくジョグダイヤル６の回転の検出が不可能であったり、検出結果に遅延が発生したりする。このような区間は、ジョグダイヤル６の回転操作を検出できない不定区間ｄＡであり、フォトインタラプタ７２の検出限界となる。不定区間内でジョグダイヤル６のスクラッチ操作など、回転方向を折り返すユーザーの操作が行われた場合、図８Ｂに示すように、不定区間ｄＢがさらに伸長し、遅延も大きくなる場合がある。
　これに対して、動作モードが第１モードである場合の回転情報算出部７１Ｄによる回転情報の算出処理においては、このような問題は発生しない。 8A and 8B are schematic views illustrating the rotation information calculation process by the rotation information calculation unit 71D in the second mode.
When the operation mode is the second mode, the rotation information calculation unit 71D obtains rotation information based on two pulse signals P1 and P2 having different phases acquired from the information acquisition unit 71A, as shown in FIG. 8A. calculate.
As described above, the photointerruptor 72 outputs, for example, a high-level signal when the light receiving unit 72B detects the light passing through the slit 61S, and outputs, for example, a low-level signal when the light is not detected. Output. However, the rotation operation of the jog dial 6 so that the light emitted from the light emitting unit 72A stays in one slit 61S, and the rotation operation of the jog dial 6 such that the light stays in the light shielding portion 61P between the two slits 61S. When is performed, the pulse signal output from the photointerruptor 72 remains at high level or low level. In this case, it may not be possible to detect the rotation of the jog dial 6 based on the signal output from the photo interrupter 72, or a delay may occur in the detection result. Such a section is an indefinite section dA in which the rotation operation of the jog dial 6 cannot be detected, and is the detection limit of the photo interrupter 72. When a user's operation such as scratching the jog dial 6 is performed in the indefinite section, the indefinite section dB may be further extended and the delay may be increased as shown in FIG. 8B.
On the other hand, in the rotation information calculation process by the rotation information calculation unit 71D when the operation mode is the first mode, such a problem does not occur.
　誤差補正部７１Ｅは、フォトインタラプタ７２による検出結果に基づいて、ジョグダイヤル６が所定角度、回転されるごとに、動作モードが第１モードであるときに算出される回転角度の累積誤差を補正する。
　ここで、第１モードにて算出される回転角度は、イメージセンサー５１の出力信号を解析したものである。しかしながら、イメージセンサー５１による検出結果には誤差が累積するため、イメージセンサー５１の出力信号に基づいて算出される回転速度、ひいては、回転速度に基づいて算出される回転角度には、上述したように誤差が含まれる場合がある。一方、第２モードでの回転情報の算出処理においては、このような誤差は含まれない。 The error correction unit 71E corrects the cumulative error of the rotation angle calculated when the operation mode is the first mode every time the jog dial 6 is rotated by a predetermined angle based on the detection result by the photointerruptor 72.
Here, the rotation angle calculated in the first mode is an analysis of the output signal of the image sensor 51. However, since errors are accumulated in the detection result by the image sensor 51, the rotation speed calculated based on the output signal of the image sensor 51, and eventually the rotation angle calculated based on the rotation speed, is as described above. Errors may be included. On the other hand, such an error is not included in the rotation information calculation process in the second mode.
　これに対し、誤差補正部７１Ｅは、フォトインタラプタ７２による検出結果に基づいて、ジョグダイヤル６が例えば０．０５度回転されるごとに、第１モードにて算出される回転角度の誤差を補正することにより、算出される回転角度に誤差が蓄積されるのを防ぐことができる。
　なお、回転角度の誤差の補正量が比較的大きい場合、誤差を補正することで、楽曲データの再生処理等に発生する不自然なギャップも大きくなる。このような問題を抑えるために、楽曲データを再生する情報処理装置Ｄは、補正量が第１閾値以上である場合、回転角度の誤差の変化量を第１閾値より小さい第２閾値以下に抑え、誤差の変化量に合わせて楽曲データの再生位置を調整し、出力される楽曲に不自然なギャップが生じないようにする処理、いわゆるスムージング処理を行ってもよい。
　情報送信部７１Ｆは、第１実施形態で説明した情報送信部５３Ｃと同様に、回転情報算出部７１Ｄによって第１モードまたは第２モードで算出された回転情報を情報処理装置Ｄに送信する。 On the other hand, the error correction unit 71E corrects the error of the rotation angle calculated in the first mode every time the jog dial 6 is rotated by, for example, 0.05 degrees, based on the detection result by the photointerruptor 72. Therefore, it is possible to prevent an error from being accumulated in the calculated rotation angle.
When the correction amount of the rotation angle error is relatively large, the unnatural gap generated in the music data reproduction process or the like becomes large by correcting the error. In order to suppress such a problem, the information processing apparatus D that reproduces the music data suppresses the amount of change in the error of the rotation angle to the second threshold value or less, which is smaller than the first threshold value, when the correction amount is the first threshold value or more. , The reproduction position of the music data may be adjusted according to the amount of change in the error, and a so-called smoothing process may be performed so that an unnatural gap does not occur in the output music.
The information transmission unit 71F transmits the rotation information calculated in the first mode or the second mode by the rotation information calculation unit 71D to the information processing device D, similarly to the information transmission unit 53C described in the first embodiment.

　次に、回転速度算出部７１Ｂが、ジョグダイヤル６の回転速度を算出し（ステップＳ２２）、モード切替部７１Ｃが、回転速度が所定の速度未満であるか否かを判定する（ステップＳ２３）。
　ステップＳ２３の判定処理にて、回転速度が所定の速度以上であると判定すると（ステップＳ２３：ＮＯ）、制御部７１は、処理を後述するステップＳ２８に進める。 In the rotation information calculation process, first, the information acquisition unit 71A acquires the output signal of the image sensor 51 of the detection device 7 and the pulse signal output from the photointerruptor 72 (step S21).
Next, the rotation speed calculation unit 71B calculates the rotation speed of the jog dial 6 (step S22), and the mode switching unit 71C determines whether or not the rotation speed is less than a predetermined speed (step S23).
If it is determined in the determination process of step S23 that the rotation speed is equal to or higher than a predetermined speed (step S23: NO), the control unit 71 advances the process to step S28 described later.

　次に、誤差補正部７１Ｅが、回転角度が所定の角度以上であるか否かを判定する（ステップＳ２６）。
　ステップＳ２６の判定処理にて、回転角度が所定の角度以上であると判定すると（ステップＳ２６：ＹＥＳ）、誤差補正部７１Ｅが、回転角度の誤差を補正し（ステップＳ２７）、制御部７１は、処理を後述するステップＳ３０に進める。
　一方、回転角度が所定の角度未満であると判定すると（ステップＳ２６：ＮＯ）、制御部７１は、処理を後述するステップＳ３０に進める。 When it is determined in the determination process of step S23 that the rotation speed is less than a predetermined speed (step S23: YES), the mode switching unit 71C switches the operation mode in the rotation information calculation unit 71D to the first mode (step S24). ), The rotation information calculation unit 71D calculates the rotation information in the first mode (step S25).
Next, the error correction unit 71E determines whether or not the rotation angle is equal to or greater than a predetermined angle (step S26).
When it is determined in the determination process of step S26 that the rotation angle is equal to or greater than a predetermined angle (step S26: YES), the error correction unit 71E corrects the rotation angle error (step S27), and the control unit 71 determines. The process proceeds to step S30 described later.
On the other hand, if it is determined that the rotation angle is less than a predetermined angle (step S26: NO), the control unit 71 advances the process to step S30 described later.
　ステップＳ２３の判定処理にて、回転速度が所定の速度以上であると判定すると（ステップＳ２３：ＮＯ）、モード切替部７１Ｃが、回転情報算出部７１Ｄにおける動作モードを第２モードに切り替え（ステップＳ２８）、回転情報算出部７１Ｄが、第２モードで回転情報を算出する（ステップＳ２９）。この後、制御部７１は、処理を後述するステップＳ３０に進める。 When it is determined in the determination process of step S23 that the rotation speed is equal to or higher than a predetermined speed (step S23: NO), the mode switching unit 71C switches the operation mode in the rotation information calculation unit 71D to the second mode (step S28). ), The rotation information calculation unit 71D calculates the rotation information in the second mode (step S29). After that, the control unit 71 advances the process to step S30, which will be described later.

Just do it. In this case, if the operation mode is the first mode, the control unit 71 may omit step S24 and proceed to step S25, and if the operation mode is the second mode, step S28 may be omitted. Then, the process may proceed to step S29.
　［第２実施形態の効果］
　以上説明した本実施形態に係る操作装置によれば、第１実施形態に係る操作装置１と同様の効果を奏することができる他、以下の効果を奏することができる。

　このような構成によれば、フォトインタラプタを用いた回転操作の検出と、第１実施形態で説明したイメージセンサー５１を用いた回転操作の検出とを選択的に実行できる。これにより、ジョグダイヤル６の回転の検出が不可能な場合、及び、ジョグダイヤル６の回転の検出に遅延が発生する場合が生じることを抑制でき、回転操作子であるジョグダイヤル６の回転操作の検出精度を高めることができる。 [Effect of the second embodiment]
According to the operation device according to the present embodiment described above, the same effect as that of the operation device 1 according to the first embodiment can be obtained, and the following effects can be obtained.
The operating device includes a detection device 7. The detection device 7 includes the image sensor 51 which is a first detection unit, a photo interrupter 72 which is a second detection unit, and a rotation information calculation unit 71D which calculates rotation information according to an operation mode.
The photo interrupter 72 has a light emitting unit 72A and a light receiving unit 72B that receives light emitted from the light emitting unit 72A. The photointerruptors 72 are provided at equal intervals along the circumferential direction centered on the rotation axis Rx of the jog dial 6 which is a rotation controller among the disks 61 which are the detected portions, and the light emitted from the light emitting unit 72A is emitted. A plurality of slits 61S that pass through and a plurality of light-shielding portions 61P that are provided between the plurality of slits 61S and shield the light emitted from the light-emitting unit 72A are targeted for detection.
The rotation information calculation unit 71D executes either the calculation of the rotation information based on the output signal of the image sensor 51 or the calculation of the rotation information based on the pulse signal indicating the detection result by the photointerruptor 72 according to the operation mode. ..
According to such a configuration, it is possible to selectively execute the detection of the rotation operation using the photo interrupter and the detection of the rotation operation using the image sensor 51 described in the first embodiment. As a result, it is possible to suppress the case where the rotation of the jog dial 6 cannot be detected and the case where the detection of the rotation of the jog dial 6 is delayed, and the detection accuracy of the rotation operation of the jog dial 6 which is a rotation controller can be improved. Can be enhanced.
　検出装置７は、イメージセンサー５１の出力信号に基づいて、ジョグダイヤル６の回転速度を算出する回転速度算出部７１Ｂと、算出された回転速度に応じて、回転情報算出部７１Ｄによる動作モードを切り替えるモード切替部７１Ｃ（自動モード切替部）と、をさらに備える。
　このような構成によれば、ジョグダイヤル６の回転速度に応じて、イメージセンサー５１の出力信号に基づいて回転情報を算出する第１モードと、フォトインタラプタ７２から出力されたパルス信号に基づいて回転情報を算出する第２モードとのうち、より検出に適した動作モードに切り替えることができ、ユーザーの操作に応じたジョグダイヤル６の回転操作の検出精度を高めることができる。 The detection device 7 is a mode in which the rotation speed calculation unit 71B for calculating the rotation speed of the jog dial 6 and the operation mode by the rotation information calculation unit 71D are switched according to the calculated rotation speed based on the output signal of the image sensor 51. A switching unit 71C (automatic mode switching unit) is further provided.
According to such a configuration, the first mode for calculating the rotation information based on the output signal of the image sensor 51 according to the rotation speed of the jog dial 6 and the rotation information based on the pulse signal output from the photointerruptor 72. Of the second mode for calculating the above, it is possible to switch to an operation mode more suitable for detection, and it is possible to improve the detection accuracy of the rotation operation of the jog dial 6 according to the user's operation.
　自動モード切替部としての機能を有するモード切替部７１Ｃは、回転速度が所定の速度より遅い場合には、回転情報算出部７１Ｄによりイメージセンサー５１の出力信号に基づいて回転情報を算出させる第１モードに動作モードを切り替え、回転速度が所定の速度より速い場合には、回転情報算出部７１Ｄによりパルス信号に基づいて回転情報を算出させる第２モードに動作モードを切り替える。
　このような構成によれば、ジョグダイヤル６の回転速度に応じて、第１モードと第２モードとのうち、検出により適した動作モードに切り替えて回転情報を算出できる。特に、基本的には利点の多い第１モードに動作モードを切り替え、第１モードでは対応が不十分な場合には第２モードに動作モードを自動的に切り替えることも可能であり、動作モードを相補的に切り替えて活用することができる。 When the rotation speed is slower than a predetermined speed, the mode switching unit 71C having a function as an automatic mode switching unit has a first mode in which the rotation information calculation unit 71D calculates rotation information based on the output signal of the image sensor 51. When the rotation speed is faster than the predetermined speed, the operation mode is switched to the second mode in which the rotation information calculation unit 71D calculates the rotation information based on the pulse signal.
According to such a configuration, the rotation information can be calculated by switching between the first mode and the second mode, which is more suitable for detection, according to the rotation speed of the jog dial 6. In particular, it is basically possible to switch the operation mode to the first mode, which has many advantages, and automatically switch the operation mode to the second mode when the correspondence is insufficient in the first mode. It can be used by switching in a complementary manner.
　検出装置７は、操作部３をユーザーの操作を受け付ける受付部とし、ユーザーの操作に応じて、動作モードを第１モードまたは第２モードに切り替えるモード切替部７１Ｃ（手動モード切替部）を備える。
　このような構成により、ユーザーの用途及び好み等に応じて回転情報を算出する動作モードを切り替えることができる。 The detection device 7 has an operation unit 3 as a reception unit that accepts user operations, and includes a mode switching unit 71C (manual mode switching unit) that switches the operation mode between the first mode and the second mode according to the user's operation.
With such a configuration, it is possible to switch the operation mode for calculating the rotation information according to the user's application, preference, and the like.
　誤差補正部７１Ｅは、フォトインタラプタ７２による受光結果に基づいて、ジョグダイヤル６が所定角度、回転される毎に、イメージセンサー５１の出力信号に基づいて算出した回転角度の誤差を補正する。
　このような構成によれば、イメージセンサー５１による検出の特性上発生する誤差を適切に補正でき、回転操作の検出精度を高めることができる。 The error correction unit 71E corrects the error of the rotation angle calculated based on the output signal of the image sensor 51 every time the jog dial 6 is rotated by a predetermined angle based on the light receiving result by the photointerruptor 72.
With such a configuration, it is possible to appropriately correct an error that occurs due to the characteristics of detection by the image sensor 51, and it is possible to improve the detection accuracy of the rotation operation.

However, the mode switching unit 71C may switch the operation mode according to other elements. For example, the mode switching unit 71C may switch the operation mode according to the touch position with respect to the jog dial 6. In this case, the operation modes are the first mode and the second mode depending on whether the user touches a surface parallel to the top surface 2A of the housing 2 or the peripheral edge of the rotating body 41 on the surface of the rotating body 41.
