　パネル部６１０は、ＬＣＤ部６２０の本体構成部６３０に向かう側の面とは反対側の面に装着される面状でかつ透明の部材であり、ペン１０００を用いたユーザによる情報の入力を受け付ける。パネル部６１０は、例えば透明のガラスあるいは樹脂等により構成されており、ＬＣＤ部６２０に表示されたアイコン６２１等の画像が表示される。 The panel unit 610 is a planar and transparent member that is attached to the surface of the LCD unit 620 opposite to the surface facing the main body component 630, and accepts input of information by the user using the pen 1000. . The panel unit 610 is made of, for example, transparent glass or resin, and displays an image such as an icon 621 displayed on the LCD unit 620.
　このためパネル部６１０は、ＬＣＤ部６２０に表示されたアイコン６２１のユーザからの選択を受け付け、電子機器６００が有するいずれかの機能を選択するための入力を受け付けることができる。 Therefore, the panel unit 610 can accept selection from the user of the icon 621 displayed on the LCD unit 620, and can accept an input for selecting any of the functions of the electronic device 600.
　また本体構成部６３０はマイク９１０を有している。図１に示すように、本実施形態に係るマイク９１０は、パネル部６１０が本体構成部６３０に装着される際にマイク９１０がパネル部６１０に接触する位置、つまり、本体構成部６３０がパネル部６１０に相対する面から音声を取り入れる位置に配置されている。 The main body component 630 has a microphone 910. As shown in FIG. 1, the microphone 910 according to the present embodiment has a position where the microphone 910 contacts the panel unit 610 when the panel unit 610 is attached to the main body component 630, that is, the main body component 630 is the panel unit. It is arranged at a position for taking in sound from the surface opposite to 610.
　本実施形態に係るＬＣＤ部６２０及びパネル部６１０は、長方形の平面形状をしており、本体構成部６３０に形成されている所定の装着位置に装着される。なお、ＬＣＤ部６２０及びパネル部６１０の形状は平面の長方形に限られず、広く一般的に多角形でもよい。また円形や楕円形でもよく、さらに平面ではなく曲面を呈してもよい。 The LCD unit 620 and the panel unit 610 according to the present embodiment have a rectangular planar shape, and are mounted at predetermined mounting positions formed in the main body constituting unit 630. The shapes of the LCD unit 620 and the panel unit 610 are not limited to planar rectangles, but may be wide and generally polygonal. Further, it may be circular or elliptical, and may have a curved surface instead of a flat surface.
　図２～図３は、本実施形態に係る電子機器６００がペン１０００による入力操作を受け付けるために備える構成を示す図である。なお図２には、ＬＣＤ部６２０は省略されている。 FIGS. 2 to 3 are diagrams showing a configuration provided for the electronic device 600 according to the present embodiment to accept an input operation with the pen 1000. FIG. In FIG. 2, the LCD unit 620 is omitted.
　まず図３を参照しながら、本実施形態に係るペン１０００の構成について説明する。 First, the configuration of the pen 1000 according to the present embodiment will be described with reference to FIG.
　ペン１０００は、電子機器６００へ各種情報の入力を行うために用いられる装置であり、先端が開口する中空筒状のペン本体１２００と、ペン本体１２００に収容される共振共鳴回路１１００と、を有して構成されている。 The pen 1000 is a device used to input various types of information to the electronic device 600, and includes a hollow cylindrical pen body 1200 having an open tip and a resonance resonance circuit 1100 housed in the pen body 1200. Configured.
　共振共鳴回路１１００は、周波数ｆの電波に同調するように形成されており、周波数ｆの電波のエネルギーを効率的に吸収する。このようにして、共振共鳴回路１１００は、無接点給電（無線給電とも記す）によりエネルギーを蓄積する。また共振共鳴回路１１００は、ペン本体１２００の先端部の開口からペン先として一端が突出するように設けられた棒状のフェライト１１１０と、フェライト１１１０の周囲を巻回するコイル１１２１と、コイル１１２１に電気的に接続されて、コイル１１２１と共にＬＣ回路を構成するコンデンサ１１２２とを有して構成される。 The resonant resonance circuit 1100 is formed so as to be tuned to the radio wave having the frequency f, and efficiently absorbs the energy of the radio wave having the frequency f. In this way, the resonant resonance circuit 1100 accumulates energy by contactless power feeding (also referred to as wireless power feeding). The resonant resonance circuit 1100 includes a rod-shaped ferrite 1110 provided so that one end protrudes from the opening at the tip of the pen body 1200 as a pen tip, a coil 1121 wound around the ferrite 1110, and an electric current to the coil 1121. And a capacitor 1122 that constitutes an LC circuit together with the coil 1121.
　なお、共振共鳴回路１１００が有するコイル１１２１のインダクタンスとコンデンサ１１２２の容量は、ＬＣ回路のＱ値が高くなるように（所定値以上になるように）設定されている。このため、共振共鳴回路１１００は、受信した周波数ｆの電波のエネルギーを、コイル１１２１及びコンデンサ１１２２を有して構成されるＬＣ回路に一旦蓄積し、蓄積した電波のエネルギー（蓄積エネルギー）を周波数ｆの放出電波として送信する。つまり共振共鳴回路１１００のＬＣ回路には、電波のエネルギーが遅れて蓄積、放出され、遅れて放出された電波のエネルギー（蓄積エネルギー）を周波数ｆの電波の送信と見なす事になる。 It should be noted that the inductance of the coil 1121 and the capacitance of the capacitor 1122 included in the resonant resonance circuit 1100 are set so that the Q value of the LC circuit is increased (a predetermined value or more). For this reason, the resonant resonance circuit 1100 temporarily stores the received radio wave energy of the frequency f in an LC circuit including the coil 1121 and the capacitor 1122, and stores the stored radio wave energy (accumulated energy) at the frequency f. Is transmitted as a radio wave. That is, in the LC circuit of the resonant resonance circuit 1100, radio wave energy is accumulated and released with a delay, and the radio wave energy (accumulated energy) released with a delay is regarded as transmission of a radio wave of frequency f.
　また本実施形態に係るペン１０００は、複数の種類を有している。ペン１０００の種類は、例えばパネル部６１０上にペン先を接触させた際や、パネル部６１０に沿ってペン先を移動させた際にＬＣＤ部６２０に表示される点や線の色や太さ、模様の少なくともいずれかに応じて定められている。 The pen 1000 according to the present embodiment has a plurality of types. The type of the pen 1000 is, for example, the color or thickness of dots or lines displayed on the LCD unit 620 when the pen tip is brought into contact with the panel unit 610 or when the pen tip is moved along the panel unit 610. , Depending on at least one of the patterns.
　そして、ペン１０００が有する共振共鳴回路１１００が同調する周波数ｆは、ペン１０００の種類によって異なるように定められている。例えばペン１０００が色によって複数の種類に分類される場合を例示すれば、図８に示す周波数テーブル８９１に定義されているように、例えば黒色のペン１０００の場合は140kHz（キロヘルツ）の周波数に同調するように共振共鳴回路１１００内のコイル１１２１のインダクタンスとコンデンサ１１２２の容量が設定されている。 The frequency f with which the resonant resonance circuit 1100 included in the pen 1000 is tuned is determined to be different depending on the type of the pen 1000. For example, when the case where the pen 1000 is classified into a plurality of types according to the color is exemplified, the black pen 1000 is tuned to a frequency of 140 kHz (kilohertz) as defined in the frequency table 891 shown in FIG. Thus, the inductance of the coil 1121 and the capacitance of the capacitor 1122 in the resonant resonance circuit 1100 are set.
　従って、例えば黒色のペン１０００が140kHzの周波数の電波を受信した場合には、140kHz以外の電波を受信した場合に比べて、より大きな蓄積エネルギーをＬＣ回路に蓄え、そしてより大きなエネルギーで放出電波を発信する。 Therefore, for example, when the black pen 1000 receives a radio wave with a frequency of 140 kHz, the stored energy is stored in the LC circuit more than when a radio wave other than 140 kHz is received, and the emitted radio wave is emitted with a larger energy. send.
　次に、図２を参照しながら、電子機器６００の構成について説明する。 Next, the configuration of the electronic device 600 will be described with reference to FIG.
　図２には、電子機器６００が、パネル部６１０と、ＬＣＤ部６２０（図２には不図示）と、送受信制御部８２０と、電子機器制御部９００と、複数のアンテナコイル７１０と、マイク９１０と、を有して構成されることが示されている。 2, the electronic device 600 includes a panel unit 610, an LCD unit 620 (not shown in FIG. 2), a transmission / reception control unit 820, an electronic device control unit 900, a plurality of antenna coils 710, and a microphone 910. It is shown that it is configured to have.
　これらのうち、送受信制御部８２０、電子機器制御部９００、複数のアンテナコイル７１０及びマイク９１０は、本体構成部６３０に収容されている。 Among these, the transmission / reception control unit 820, the electronic device control unit 900, the plurality of antenna coils 710, and the microphone 910 are accommodated in the main body configuration unit 630.
　アンテナコイル７１０は空芯コイルを有して構成される。この空芯コイルは、中空にコイルを巻回することにより構成される。図２には、アンテナコイル７１０として、５つのアンテナコイル７１０Ａ、７１０Ｂ、７１０Ｃ、７１０Ｄ、７１０Ｅが記載されている。 The antenna coil 710 includes an air-core coil. This air-core coil is configured by winding a coil in a hollow space. FIG. 2 shows five antenna coils 710A, 710B, 710C, 710D, and 710E as the antenna coil 710.
　アンテナコイル７１０Ａは、パネル６１０の周囲を囲むように配置してループアンテナとして用いられ、後述する送信アンテナコイル及び受信アンテナコイルとして機能する。またアンテナコイル７１０Ｂ、７１０Ｃ、７１０Ｄ、７１０Ｅは、空芯コイルの巻回軸をパネル部６１０と交差する方向に向けて、パネル部６１０の周囲の角部に配置され、後述する受信アンテナコイルとして機能する。 The antenna coil 710A is arranged as a loop antenna so as to surround the panel 610, and functions as a transmission antenna coil and a reception antenna coil described later. The antenna coils 710B, 710C, 710D, and 710E are arranged at corners around the panel unit 610 with the winding axis of the air-core coil crossing the panel unit 610, and function as a receiving antenna coil to be described later. To do.
　なお、アンテナコイル７１０Ｂ、７１０Ｃ、７１０Ｄ、７１０Ｅは、フェライトなどのコアの周囲にコイルを巻回することにより構成してもよい。このようなアンテナコイル７１０Ｂ、７１０Ｃ、７１０Ｄ、７１０Ｅを用いることにより、指向性を向上させ、コイルの巻き数を少なくできるというメリットがある。 The antenna coils 710B, 710C, 710D, and 710E may be configured by winding a coil around a core such as ferrite. By using such antenna coils 710B, 710C, 710D, and 710E, there is an advantage that directivity can be improved and the number of turns of the coil can be reduced.
　上述した送信アンテナコイルは、所定周波数ｆの電波（送信電波）を送信するアンテナである。この送信電波は、周波数ｆに同調するペン１０００によって最も効率良く受信される。なお上述したように、このペン１０００は、蓄積した送信電波のエネルギー（蓄積エネルギー）を周波数ｆの放出電波として送信する。 The transmission antenna coil described above is an antenna that transmits radio waves (transmission radio waves) having a predetermined frequency f. This transmitted radio wave is received most efficiently by the pen 1000 that is tuned to the frequency f. As described above, the pen 1000 transmits the accumulated transmission radio wave energy (accumulated energy) as an emission radio wave of frequency f.
　一方、受信アンテナコイルは、ペン１０００から放出される放出電波を受信するアンテナである。 On the other hand, the receiving antenna coil is an antenna that receives the emitted radio wave emitted from the pen 1000.
　このように、本実施形態に係る電子機器６００は、パネル部６１０の周囲に送信アンテナコイル及び受信アンテナコイルを配置するように構成されているため、パネル部６１０の面上にアンテナを配置する必要がない。そのため本実施形態に係る電子機器６００は、パネル部６１０の透明度を低下させることなく、電波あるいは電磁波の共振共鳴回路１１００を組込んだペン１０００による情報入力を行うことが可能になる。 As described above, since the electronic apparatus 600 according to the present embodiment is configured to arrange the transmission antenna coil and the reception antenna coil around the panel unit 610, it is necessary to arrange the antenna on the surface of the panel unit 610. There is no. Therefore, the electronic apparatus 600 according to the present embodiment can input information with the pen 1000 incorporating the resonance resonance circuit 1100 for radio waves or electromagnetic waves without reducing the transparency of the panel unit 610.
　また、本実施形態に係るアンテナコイル７１０は、それぞれ、空芯コイルの巻回軸がパネル部６１０に交差する方向（例えば直交する方向）に向け、かつ各巻回軸が平行になるようにパネル部６１０の周囲に配置されている。このような態様により、各アンテナコイル７１０の指向性の向きを揃えることができるので、ペン１０００から放出される放出電波をより感度良く受信することが可能になる。 In addition, the antenna coil 710 according to the present embodiment has a panel portion so that the winding axis of the air-core coil is directed in a direction intersecting the panel portion 610 (for example, a direction orthogonal thereto) and the winding axes are parallel to each other. 610 is arranged around the periphery. According to such an aspect, the directivity directions of the antenna coils 710 can be aligned, so that the radio waves emitted from the pen 1000 can be received with higher sensitivity.
　また本実施形態に係るアンテナコイル７１０Ａをループアンテナとして機能させることにより、アンテナコイル７１０Ａからペン１０００に対して効率よく無接点給電（無線給電とも記す）を行うことが可能となる。また本実施形態に係るアンテナコイル７１０Ａのように、ループアンテナを送信アンテナコイル及び受信アンテナコイルとして用いることにより、ペン１０００をパネル部６１０に近接させる場合及び遠ざける場合のペン１０００とパネル部６１０との間の距離の変化を検知し、ペン１０００をパネル部６１０に接触させた場合の押圧力すなわち筆圧を検知することも可能となる。さらに、この筆圧を検知して別途の制御ロジックと組み合わせることにより、電子機器６００の引き起こし（パワーアップ）の制御を行うことも可能となる。 Further, by causing the antenna coil 710A according to this embodiment to function as a loop antenna, it is possible to efficiently perform non-contact power feeding (also referred to as wireless power feeding) from the antenna coil 710A to the pen 1000. Further, by using the loop antenna as the transmitting antenna coil and the receiving antenna coil as in the antenna coil 710A according to the present embodiment, the pen 1000 and the panel unit 610 can be used when the pen 1000 is brought close to and away from the panel unit 610. It is also possible to detect a pressing force, that is, a writing pressure when the pen 1000 is brought into contact with the panel unit 610 by detecting a change in the distance between them. Furthermore, by detecting this writing pressure and combining it with a separate control logic, it is possible to control the cause (power up) of the electronic device 600.
　なお、図２に示した電子機器６００においては、受信アンテナコイルとして機能させる４つのアンテナコイル７１０Ｂ、７１０Ｃ、７１０Ｄ、７１０Ｅをパネル部６１０の角部に配置した場合を示したが、受信アンテナコイルを４つ以上のアンテナコイル７１０を用いて構成し、パネル部６１０の角部以外の場所にもアンテナコイル７１０を配置してもよい。このような態様により、ペン１０００の位置をより正確に特定することも可能となる。なお、本実施形態に係る電子機器６００がペン１０００の位置を特定する方法については後述する。 In the electronic device 600 shown in FIG. 2, the case where the four antenna coils 710B, 710C, 710D, and 710E that function as reception antenna coils are arranged at the corners of the panel unit 610 is shown. Four or more antenna coils 710 may be used, and the antenna coil 710 may be disposed at a place other than the corner of the panel unit 610. With such an aspect, the position of the pen 1000 can be specified more accurately. Note that a method for the electronic device 600 according to the present embodiment to specify the position of the pen 1000 will be described later.
　また電子機器６００は、受信アンテナコイルをパネル部６１０の周囲に配置する構成であれば、角部に配置しない構成でもよい。さらに受信アンテナコイルを構成するアンテナコイル７１０は３つでもよい。 Further, the electronic device 600 may have a configuration in which the receiving antenna coil is not disposed in the corner portion as long as the receiving antenna coil is disposed around the panel portion 610. Further, the number of antenna coils 710 constituting the receiving antenna coil may be three.
　アンテナコイル７１０Ａ、７１０Ｂ、７１０Ｃ、７１０Ｄ、７１０Ｅは、後述する送受信制御部８２０が有するドライバ回路５００にそれぞれ接続されている。 The antenna coils 710A, 710B, 710C, 710D, and 710E are respectively connected to a driver circuit 500 included in a transmission / reception control unit 820 described later.
　そして、電子機器制御部９００がドライバ回路５００を制御することにより、アンテナコイル７１０Ａによる送信電波の送信や、アンテナコイル７１０Ａ、７１０Ｂ、７１０Ｃ、７１０Ｄ、７１０Ｅによる放出電波の受信が制御される。 Then, when the electronic device control unit 900 controls the driver circuit 500, transmission of the transmission radio wave by the antenna coil 710A and reception of the emission radio wave by the antenna coils 710A, 710B, 710C, 710D, 710E are controlled.
　なお、ドライバ回路５００は、アンテナコイル７１０Ａ、７１０Ｂ、７１０Ｃ、７１０Ｄ、７１０Ｅに個別に設けられており、電子機器制御部９００は、各ドライバ回路５００を並列に制御することにより、アンテナコイル７１０Ａ、７１０Ｂ、７１０Ｃ、７１０Ｄ、７１０Ｅによる放出電波の受信を同時並列に行うことができる。 The driver circuit 500 is individually provided in the antenna coils 710A, 710B, 710C, 710D, and 710E, and the electronic device control unit 900 controls the antenna circuits 710A and 710B by controlling the driver circuits 500 in parallel. , 710C, 710D, and 710E can simultaneously receive the radio waves emitted in parallel.
　このように制御することにより、送受信制御部８２０は、複数の受信アンテナコイルにより受信した放出電波の処理を同時並列に行うことが可能となり、ペン１０００の位置特定処理を高速化することが可能となる。 By controlling in this way, the transmission / reception control unit 820 can simultaneously process the emitted radio waves received by the plurality of receiving antenna coils in parallel, and can speed up the position specifying process of the pen 1000. Become.
　また電子機器制御部９００は、図７に示すように、送信アンテナコイル（本実施形態ではアンテナコイル７１０Ａ）による送信電波の送信（Ｔ１、Ｔ３、Ｔ５で示す期間）と、受信アンテナコイル（本実施形態ではアンテナコイル７１０Ａ、７１０Ｂ、７１０Ｃ、７１０Ｄ、７１０Ｅ）によるペン１０００から放出される放出電波の受信（Ｔ２、Ｔ４、Ｔ６で示す期間）と、が所定時間毎に交互に繰り返し行われるように、上記の送信アンテナコイル及び受信アンテナコイルを制御する。 In addition, as shown in FIG. 7, the electronic device control unit 900 transmits transmission radio waves (periods indicated by T1, T3, and T5) by a transmission antenna coil (antenna coil 710A in this embodiment) and a reception antenna coil (this embodiment). In the embodiment, the reception of radio waves emitted from the pen 1000 by the antenna coils 710A, 710B, 710C, 710D, and 710E (periods indicated by T2, T4, and T6) is alternately repeated at predetermined time intervals. The transmission antenna coil and the reception antenna coil are controlled.
　このような態様によって、受信アンテナコイルがペン１０００からの放出電波を受信する期間内には送信アンテナコイルからの送信電波の送信がなされないため、受信アンテナコイルはペン１０００からの放出電波を効率的に受信することが可能となり、ペン１０００の位置特定精度を向上させることが可能となる。 In this manner, the transmission antenna coil does not transmit the transmission radio wave from the transmission antenna coil during the period in which the reception antenna coil receives the radio emission from the pen 1000. Therefore, the reception antenna coil efficiently transmits the radio emission from the pen 1000. Thus, the position specifying accuracy of the pen 1000 can be improved.
　図２に戻って、送受信制御部８２０は、発振回路７３０と、ドライバ回路５００と、フィルタ回路８４０と、検波回路８５０と、ＡＤ変換回路８６０、８６１と、信号解析部８７０と、位置特定テーブル８９０と、周波数テーブル８９１と、を有して構成されている。 Returning to FIG. 2, the transmission / reception control unit 820 includes an oscillation circuit 730, a driver circuit 500, a filter circuit 840, a detection circuit 850, AD conversion circuits 860 and 861, a signal analysis unit 870, and a position specifying table 890. And a frequency table 891.
　なお、図２には、記載簡略化のために、ドライバ回路５００、フィルタ回路８４０、検波回路８５０、及びＡＤ変換回路８６０は、一つずつ記載されているが、それぞれ、アンテナコイル７１０Ａ、７１０Ｂ、７１０Ｃ、７１０Ｄ、７１０Ｅごとに設けられている。 In FIG. 2, for simplification of description, the driver circuit 500, the filter circuit 840, the detection circuit 850, and the AD conversion circuit 860 are shown one by one, but the antenna coils 710A, 710B, It is provided for each of 710C, 710D, and 710E.
　発振回路７３０は、送信アンテナコイルから周波数ｆの送信電波が送信されるように、交流電圧を発生する回路である。発振回路７３０が発生する交流電圧の周波数は、電子機器制御部９００によって制御される。 The oscillation circuit 730 is a circuit that generates an AC voltage so that a transmission radio wave having a frequency f is transmitted from the transmission antenna coil. The frequency of the AC voltage generated by the oscillation circuit 730 is controlled by the electronic device control unit 900.
　具体的には、電子機器制御部９００は、送信アンテナコイルによる送信電波の送信と受信アンテナコイルによるペン１０００からの放出電波の受信とを交互に行う際に、送信電波が送信される毎に異なる周波数で送信されるように、発振回路７３０が発生する交流電圧の周波数を変更する。 Specifically, the electronic device control unit 900 is different each time a transmission radio wave is transmitted when transmission of a transmission radio wave by the transmission antenna coil and reception of an emission radio wave from the pen 1000 by the reception antenna coil are alternately performed. The frequency of the alternating voltage generated by the oscillation circuit 730 is changed so that the frequency is transmitted.
　より具体的には、電子機器制御部９００は、ペン１０００の種類に対応して設定されているそれぞれの周波数で送信電波が順次送信されるように発振回路７３０を制御する。そして電子機器制御部９００は、ペン１０００の種類に対応する各周波数での送信電波の送信を一通り終えたら、再度繰り返して各周波数での送信電波の送信を行う。 More specifically, the electronic device control unit 900 controls the oscillation circuit 730 so that the transmission radio wave is sequentially transmitted at each frequency set corresponding to the type of the pen 1000. When the electronic device control unit 900 completes transmission of the transmission radio wave at each frequency corresponding to the type of the pen 1000, the electronic device control unit 900 repeats transmission of the transmission radio wave at each frequency again.
　このため図７に示すように、Ｔ１で示す期間においては、黒色のペン１０００に対応する周波数で送信電波が送信され、Ｔ３で示す期間においては、赤色のペン１０００に対応する周波数で送信電波が送信され、Ｔ５で示す期間においては、緑色のペン１０００に対応する周波数で送信電波が送信される。 Therefore, as shown in FIG. 7, the transmission radio wave is transmitted at a frequency corresponding to the black pen 1000 in the period indicated by T1, and the transmission radio wave is transmitted at the frequency corresponding to the red pen 1000 in the period indicated by T3. In the period indicated by T5, the transmission radio wave is transmitted at a frequency corresponding to the green pen 1000.
　発振回路７３０によって生成された交流電圧は、送信信号としてドライバ回路５００に入力されて増幅される。そして送信アンテナコイルから送信電波が送信される。 The AC voltage generated by the oscillation circuit 730 is input to the driver circuit 500 as a transmission signal and amplified. A transmission radio wave is transmitted from the transmission antenna coil.
　ペン１０００からの放出電波は、アンテナコイル７１０Ａ、７１０Ｂ、７１０Ｃ、７１０Ｄ、７１０Ｅによってそれぞれ受信され、各アンテナコイル７１０Ａ、７１０Ｂ、７１０Ｃ、７１０Ｄ、７１０Ｅに個別に接続されたそれぞれのドライバ回路５００、フィルタ回路８４０、検波回路８５０によって、それぞれ増幅、ノイズ除去、復調され、ＡＤ変換回路８６０によってディジタル信号に変換されたのちに、信号解析部８７０に入力される。 Radio waves emitted from the pen 1000 are received by the antenna coils 710A, 710B, 710C, 710D, and 710E, respectively, and the driver circuits 500 and filter circuits individually connected to the antenna coils 710A, 710B, 710C, 710D, and 710E, respectively. The signal is amplified, noise-removed, and demodulated by the detection circuit 850 and the detection circuit 850, converted into a digital signal by the AD conversion circuit 860, and then input to the signal analysis unit 870.
　信号解析部８７０は、受信アンテナコイルが受信した放出電波を検知することによりペン１０００を検知する。信号解析部８７０は、受信強度検知部８７１と位置特定部８７２とを備えている。 The signal analysis unit 870 detects the pen 1000 by detecting the emitted radio wave received by the receiving antenna coil. The signal analysis unit 870 includes a reception intensity detection unit 871 and a position specifying unit 872.
　受信強度検知部８７１は、複数の受信アンテナコイル（アンテナコイル７１０Ａ、７１０Ｂ、７１０Ｃ、７１０Ｄ、７１０Ｅ）が受信したペン１０００からの放出電波のそれぞれの受信強度を検知する。 The reception intensity detection unit 871 detects the reception intensity of each of the radio waves emitted from the pen 1000 received by a plurality of reception antenna coils (antenna coils 710A, 710B, 710C, 710D, 710E).
　具体的には、受信強度検知部８７１は、アンテナコイル７１０Ａ、７１０Ｂ、７１０Ｃ、７１０Ｄ、７１０Ｅが受信したペン１０００からの放出電波の受信強度(RSSI)を所定時間毎に計測し、メモリ（不図示）に記録している。また受信強度検知部８７１は、ＡＤ変換回路８６１を介して入力される発振回路７３０からの信号に基づいて、アンテナコイル７１０Ａから送信される送信電波の周波数ｆを検知している。 Specifically, the reception intensity detector 871 measures the reception intensity (RSSI) of radio waves emitted from the pen 1000 received by the antenna coils 710A, 710B, 710C, 710D, and 710E at predetermined time intervals, and stores them in a memory (not shown). ) Is recorded. The received intensity detector 871 detects the frequency f of the transmission radio wave transmitted from the antenna coil 710A based on the signal from the oscillation circuit 730 input via the AD conversion circuit 861.
　このようにして、アンテナコイル７１０Ａ、７１０Ｂ、７１０Ｃ、７１０Ｄ、７１０Ｅが受信したペン１０００からの放出電波が、送受信制御部８２０に取り込まれる。 Thus, the radio waves emitted from the pen 1000 received by the antenna coils 710A, 710B, 710C, 710D, and 710E are taken into the transmission / reception control unit 820.
　位置特定部８７２は、各受信アンテナコイル（アンテナコイル７１０Ａ、７１０Ｂ、７１０Ｃ、７１０Ｄ、７１０Ｅ）が受信した放出電波のそれぞれの受信強度に基づいて、パネル部６１０におけるペン１０００の位置を特定する。 The position specifying unit 872 specifies the position of the pen 1000 in the panel unit 610 based on the reception intensity of each of the emitted radio waves received by each receiving antenna coil (antenna coils 710A, 710B, 710C, 710D, 710E).
　例えば、ペン１０００の先端部が、図９に示すパネル部６１０のＰの位置（座標(i,j)）に触れているとする。そうすると、このペン１０００から放出される放出電波は、複数の受信アンテナコイル（アンテナコイル７１０Ａ、７１０Ｂ、７１０Ｃ、７１０Ｄ、７１０Ｅ）によってそれぞれ受信される。 For example, assume that the tip of the pen 1000 touches the position P (coordinates (i, j)) of the panel unit 610 shown in FIG. Then, the radio waves emitted from the pen 1000 are received by the plurality of receiving antenna coils (antenna coils 710A, 710B, 710C, 710D, and 710E), respectively.
　放出電波の受信強度は、Ｐの位置が受信アンテナコイルから遠ざかるほど小さくなり、原理的にはＰの位置と各受信アンテナコイルとの距離の２乗に反比例して小さくなる。 The received intensity of the emitted radio wave decreases as the position of P moves away from the receiving antenna coil, and in principle decreases in inverse proportion to the square of the distance between the position of P and each receiving antenna coil.
　そのため、位置特定部８７２は、４つのアンテナコイル７１０Ｂ、７１０Ｃ、７１０Ｄ、７１０Ｅによってそれぞれ受信された放出電波の受信強度を用いて、パネル部６１０上における位置Ｐの座標（i,j）の値を求める。具体的には、位置特定部８７２は、４つのアンテナコイル７１０Ｂ、７１０Ｃ、７１０Ｄ、７１０Ｅによってそれぞれ受信された放出電波の受信強度の相対比を算出して、図１０に示す位置特定テーブル８９０の「Ｂ」「Ｃ」「Ｄ」「Ｅ」欄を参照し、受信強度の相対比に最も近い値の行を検索することで、Ｐの位置座標（i,j）を特定する。 Therefore, the position specifying unit 872 uses the received intensity of the emitted radio waves received by the four antenna coils 710B, 710C, 710D, and 710E to calculate the value of the coordinates (i, j) of the position P on the panel unit 610. Ask. Specifically, the position specifying unit 872 calculates the relative ratios of the received intensities of the radio waves received by the four antenna coils 710B, 710C, 710D, and 710E, and displays “ The position coordinates (i, j) of P are specified by searching for the row having the value closest to the relative ratio of the received intensity with reference to the columns “B”, “C”, “D”, and “E”.
　位置特定テーブル８９０Ｂの「Ｂ」欄、「Ｃ」欄、「Ｄ」欄、「Ｅ」欄には、事前に行った実験等によって測定された、アンテナコイル７１０Ｂ、７１０Ｃ、７１０Ｄ、７１０Ｅが受信する放出電波の受信強度の相対比が、ペン１０００のパネル部６１０上の位置座標（i,j）ごとに記録されている。 In the “B” column, “C” column, “D” column, and “E” column of the position specifying table 890B, the antenna coils 710B, 710C, 710D, and 710E measured by a prior experiment or the like receive. The relative ratio of the received radio wave intensity is recorded for each position coordinate (i, j) on the panel unit 610 of the pen 1000.
　以上の様にして、位置特定部８７２は、受信強度検知部８７１によって検知された放出電波の受信強度に基づいて、パネル部６１０におけるペン１０００の位置を特定する。 As described above, the position specifying unit 872 specifies the position of the pen 1000 in the panel unit 610 based on the reception intensity of the emitted radio wave detected by the reception intensity detection unit 871.
　そして位置特定部８７２はペン１０００の位置（図９におけるＰ点）を特定して、電子機器制御部９００に通知する。 Then, the position specifying unit 872 specifies the position of the pen 1000 (P point in FIG. 9) and notifies the electronic device control unit 900 of it.
　そして電子機器制御部９００は、例えば、図９のＰ点の位置に点を描画させるための処理をＬＣＤ部６２０に対して行う。 And the electronic device control part 900 performs the process for making a point draw in the position of P point of FIG. 9 with respect to the LCD part 620, for example.
　本実施形態のように、位置特定テーブル８９０を用いてペン１０００の位置を特定するようにすることによって、放出電波の受信強度からペン１０００の位置を算出する際に正弦関数などの複雑な計算を行うことが不要となるので、電子機器６００はより短時間にペン１０００の位置を特定することが可能となる。 As in this embodiment, by specifying the position of the pen 1000 using the position specifying table 890, a complicated calculation such as a sine function is performed when calculating the position of the pen 1000 from the reception intensity of the emitted radio wave. Since this need not be performed, the electronic apparatus 600 can specify the position of the pen 1000 in a shorter time.
　ところで上述した様に、送受信制御部８２０は、ペン１０００の種類に対応して設定されているそれぞれの周波数を順番に切り替えながら送信アンテナコイルから送信電波を送信する。 By the way, as described above, the transmission / reception control unit 820 transmits the transmission radio wave from the transmission antenna coil while sequentially switching the respective frequencies set corresponding to the type of the pen 1000.
　例えば、送受信制御部８２０は、図７に示すように、期間Ｔ１においては黒色のペン１０００に同調する周波数140kHzで送信電波を送信し、期間Ｔ３においては赤色のペン１０００に同調する周波数149kHzで送信電波を送信し、期間Ｔ５においては緑色のペン１０００に同調する周波数158kHzで送信電波を送信する。 For example, as shown in FIG. 7, the transmission / reception control unit 820 transmits a transmission radio wave at a frequency of 140 kHz tuned to the black pen 1000 in the period T1, and transmits at a frequency of 149 kHz tuned to the red pen 1000 in the period T3. The radio wave is transmitted, and in the period T5, the transmission radio wave is transmitted at a frequency of 158 kHz tuned to the green pen 1000.
　このとき、パネル部６１０に接触しているペン１０００が緑色であった場合には、このペン１０００は158kHzの送信電波に同調する共振共鳴回路１１００を備えているため、図７に示す期間Ｔ６において受信アンテナコイルによって受信される受信強度は、期間Ｔ２やＴ４などのＴ６以外の期間においてそれぞれ受信アンテナコイルによって受信される受信強度に比べて相対的に大きくなる。 At this time, when the pen 1000 that is in contact with the panel unit 610 is green, the pen 1000 includes the resonance resonance circuit 1100 that is tuned to the transmission radio wave of 158 kHz. Therefore, in the period T6 shown in FIG. The reception intensity received by the reception antenna coil is relatively higher than the reception intensity received by the reception antenna coil in periods other than T6 such as periods T2 and T4.
　このように、受信アンテナコイルが受信する放出電波の強度は、ペン１０００の種類に応じて、受信アンテナコイルが放出電波を受信する毎に変化する。 As described above, the intensity of the emitted radio wave received by the receiving antenna coil changes every time the receiving antenna coil receives the emitted radio wave according to the type of the pen 1000.
　このため、位置特定部８７２は、受信アンテナコイルが放出電波を受信する毎に放出電波の受信強度が変化することを利用して、受信強度検知部８７１によって検知された放出電波の受信強度に基づいて、ペン１０００の種類を特定することができる。 For this reason, the position specifying unit 872 uses the fact that the reception intensity of the emitted radio wave changes every time the reception antenna coil receives the emitted radio wave, and based on the reception intensity of the emitted radio wave detected by the reception intensity detecting unit 871. Thus, the type of the pen 1000 can be specified.
　このようにして、位置特定部８７２はペン１０００の位置（図９におけるＰ点）及び種類（緑色）を特定して、電子機器制御部９００に通知する。 In this way, the position specifying unit 872 specifies the position (point P in FIG. 9) and type (green) of the pen 1000 and notifies the electronic device control unit 900 of the position.
　そして電子機器制御部９００は、例えば、図９のＰ点の位置にペン１０００の種類に応じた太さ（サイズ）や色の点を描画させるための処理をＬＣＤ部６２０に対して行う。 Then, the electronic device control unit 900 performs, for example, processing on the LCD unit 620 to draw a thickness (size) or color point corresponding to the type of the pen 1000 at the position of the point P in FIG.
　なお、電子機器制御部９００は、送信アンテナコイル及び受信アンテナコイルの制御を、以下に説明する第１モードと第２モードとに分けて行ってもよい。 In addition, the electronic device control unit 900 may perform control of the transmission antenna coil and the reception antenna coil separately in a first mode and a second mode described below.
　第１モードにおいては、電子機器制御部９００は、アンテナコイル７１０Ａのみからの送信電波の発信と、アンテナコイル７１０Ａのみによる放出電波の受信と、を交互に第１所定時間を周期として繰り返すように、それぞれのドライバ回路５００を制御する。このとき、第１所定時間は、例えば０．１秒あるいは１秒程度とする。第１モードにおいては、送信アンテナコイル及び受信アンテナコイルのいずれもがアンテナコイル７１０Ａのみとなる。 In the first mode, the electronic device control unit 900 alternately repeats transmission of a transmission radio wave from only the antenna coil 710A and reception of an emission radio wave only by the antenna coil 710A with a first predetermined time as a cycle. Each driver circuit 500 is controlled. At this time, the first predetermined time is, for example, about 0.1 second or 1 second. In the first mode, both the transmitting antenna coil and the receiving antenna coil are only the antenna coil 710A.
　そして第１モードにおいて、ペン１０００がパネル部６１０に近接して、ペン１０００からの放出電波がアンテナコイル７１０Ａによって受信されると、受信強度検知部８７１によって検知される放出電波の受信強度が所定の閾値を超える。 In the first mode, when the pen 1000 is close to the panel unit 610 and the radio wave emitted from the pen 1000 is received by the antenna coil 710A, the reception intensity of the radio wave detected by the reception intensity detector 871 is set to a predetermined value. The threshold is exceeded.
　そうすると電子機器制御部９００は、送信アンテナコイル及び受信アンテナコイルの制御を第２モードに切り替える。第２モードでは、電子機器制御部９００は、アンテナコイル７１０Ａのみからの送信電波の発信と、アンテナコイル７１０Ａ、７１０Ｂ、７１０Ｃ、７１０Ｄ、７１０Ｅによる放出電波の受信と、を交互に繰り返すように、それぞれのドライバ回路５００を制御する。このときの送受信の切り替えの周期は、第１所定時間よりも短い第２所定時間とする。第２所定時間は、例えば１０ミリ秒、１ミリ秒、あるいは１００マイクロ秒程度、あるいはそれ以下とする。 Then, the electronic device control unit 900 switches the control of the transmission antenna coil and the reception antenna coil to the second mode. In the second mode, the electronic device control unit 900 repeats the transmission of the transmission radio wave only from the antenna coil 710A and the reception of the radio emission emitted by the antenna coils 710A, 710B, 710C, 710D, and 710E, respectively. The driver circuit 500 is controlled. The transmission / reception switching cycle at this time is set to a second predetermined time shorter than the first predetermined time. The second predetermined time is, for example, about 10 milliseconds, 1 millisecond, or 100 microseconds or less.
　その後、第２モードにおいて、ペン１０００がパネル部６１０から離れると、ペン１０００からの放出電波がアンテナコイル７１０Ａ、７１０Ｂ、７１０Ｃ、７１０Ｄ、７１０Ｅによって受信されなくなる。そして受信強度検知部８７１によって検知される放出電波の受信強度が所定時間継続して閾値を超えなくなると、電子機器制御部９００は、再び第１モードに制御を戻す。 Thereafter, when the pen 1000 is separated from the panel unit 610 in the second mode, the radio waves emitted from the pen 1000 are not received by the antenna coils 710A, 710B, 710C, 710D, and 710E. When the reception intensity of the emitted radio wave detected by the reception intensity detection unit 871 continues for a predetermined time and does not exceed the threshold value, the electronic device control unit 900 returns control to the first mode again.
　このような態様によれば、ペン１０００がパネル部６１０に近接していない場合の消費電力を抑制できるとともに、ペン１０００がパネル部６１０に近接した場合には、迅速にペン１０００の位置を特定し、ペン１０００による情報の入力を可能とする制御に切り替えることが可能となる。 According to such an aspect, power consumption when the pen 1000 is not close to the panel unit 610 can be suppressed, and when the pen 1000 is close to the panel unit 610, the position of the pen 1000 can be quickly identified. Thus, it is possible to switch to control that enables input of information by the pen 1000.
　次に、図４～図６、図１１、図１２等を参照しながら、本実施形態に係る電子機器制御部９００について説明する。 Next, the electronic device control unit 900 according to the present embodiment will be described with reference to FIGS. 4 to 6, FIG. 11, FIG.
　上述したように、電子機器制御部９００は、本体構成部６３０に内蔵され、電子機器６００が有する様々な機能を実現するための情報処理を実行する。例えば電子機器制御部９００は、上述した送信アンテナコイル及び受信アンテナコイルを用いたペン１０００の位置特定制御を行う。また電子機器制御部９００は、電子機器６００が有する機能を表したアイコン６２１をＬＣＤ部６２０に表示し、ユーザによるアイコン６２１の指定入力を受け付け、このアイコン６２１により指定される情報処理を実行する。 As described above, the electronic device control unit 900 is incorporated in the main body configuration unit 630 and executes information processing for realizing various functions of the electronic device 600. For example, the electronic device control unit 900 performs position specifying control of the pen 1000 using the transmission antenna coil and the reception antenna coil described above. In addition, the electronic device control unit 900 displays an icon 621 representing the function of the electronic device 600 on the LCD unit 620, accepts designation input of the icon 621 by the user, and executes information processing designated by the icon 621.
　また電子機器制御部９００は、電子機器６００の機能を停止させるための指定入力を受け付けると、電子機器６００の機能を停止させるための情報処理を実行する。このとき電子機器制御部９００は、所定の手順に従って電子機器６００内の各構成要素の機能を順次停止させていき、最終的には、電子機器制御部９００自身が有する情報処理実行機能も停止させる（いわゆる電源オフ）。 In addition, when the electronic device control unit 900 receives a designation input for stopping the function of the electronic device 600, the electronic device control unit 900 executes information processing for stopping the function of the electronic device 600. At this time, the electronic device control unit 900 sequentially stops the function of each component in the electronic device 600 according to a predetermined procedure, and finally stops the information processing execution function of the electronic device control unit 900 itself. (So-called power off).
　反対に、電子機器制御部９００は、電子機器６００の機能を開始するための指定入力を受け付けると（いわゆる電源オン）、所定の手順に従って電子機器６００内の各構成要素の機能を順次開始させていく。そして電子機器制御部９００は、電子機器制御部９００自身が有する上記の情報処理実行機能も有効にする。 On the contrary, when receiving a designation input for starting the function of electronic device 600 (so-called power-on), electronic device control unit 900 sequentially starts the function of each component in electronic device 600 according to a predetermined procedure. Go. And the electronic device control part 900 also validates said information processing execution function which the electronic device control part 900 itself has.
　電子機器制御部９００がＬＣＤ部６２０にアイコン６２１を表示している様子を図１１に示す。図１１に示す例では、３つのアイコン６２１Ａ、６２１Ｂ、６２１ＣがＬＣＤ部６２０に表示されている。 FIG. 11 shows a state where the electronic device control unit 900 displays the icon 621 on the LCD unit 620. In the example shown in FIG. 11, three icons 621 </ b> A, 621 </ b> B, and 621 </ b> C are displayed on the LCD unit 620.
　ユーザは、ペン１０００の先端を所望のアイコン６２１の表示領域に重ねるようにしてパネル部６１０に接触あるいは近接させることによって、電子機器６００に実現させようと意図する機能に対応するアイコン６２１を選択することができる。 The user selects the icon 621 corresponding to the function intended to be realized in the electronic device 600 by bringing the tip of the pen 1000 over the display area of the desired icon 621 so as to contact or approach the panel unit 610. be able to.
　なお、アイコン６２１の形態は、図１１に示すような態様で表示された形態でなくてもよく、例えば電子機器制御部９００がＬＣＤ部６２０にウェブページを表示している場合には、このウェブページに含まれる、他のウェブページのアドレスを示すいわゆるリンク情報（テキストや画像、動画等の様々な態様で表示されるリンク情報を含む）の形態であっても良いし、電子機器制御部９００がＬＣＤ部６２０にテキストや画像、動画等を表示するためのウインドウ画面を表示している場合には、このウインドウ画面内に表示される各種の操作ボタン（印刷、データ保存、動画の再生、フォントの設定など）の形態であっても良く、ユーザが電子機器６００に実現させようと意図する何等かの機能を選択するための情報を電子機器制御部９００が取得するために表示された形態であれば良い。 The form of the icon 621 may not be the form displayed in the form as shown in FIG. 11. For example, when the electronic device control unit 900 displays a web page on the LCD unit 620, It may be in the form of so-called link information (including link information displayed in various forms such as text, images, and moving images) indicating the address of another web page included in the page, or the electronic device control unit 900 Displays a window screen for displaying text, images, movies, etc. on the LCD unit 620, various operation buttons (print, data save, movie playback, font, etc.) displayed in this window screen. The information for selecting any function that the user intends to realize in the electronic device 600 is stored in the electronic device control unit 9. 0 may be any display form to get.
　次に図４に、本実施形態に係る電子機器制御部９００を説明するための構成図を示す。電子機器制御部９００は、情報処理実行部９４０と、メモリ９５０と、ＤＳＰ（Digital Signal Processor）９３０と、を備える。また電子機器制御部９００は、送受信制御部８２０、ＬＣＤ部６２０、通信装置９６０、マイク９１０及びスピーカ９２０と接続されている。 Next, FIG. 4 shows a configuration diagram for explaining the electronic device control unit 900 according to the present embodiment. The electronic device control unit 900 includes an information processing execution unit 940, a memory 950, and a DSP (Digital Signal Processor) 930. The electronic device control unit 900 is connected to the transmission / reception control unit 820, the LCD unit 620, the communication device 960, the microphone 910, and the speaker 920.
　情報処理実行部９４０は、音楽制御部９４１と、音楽分析部９４２と、機能特定部９４３と、を備える。またＤＳＰ９３０は、データ処理部９３１と、クリック判定部９３２と、を備える。 The information processing execution unit 940 includes a music control unit 941, a music analysis unit 942, and a function specifying unit 943. The DSP 930 includes a data processing unit 931 and a click determination unit 932.
　情報処理実行部９４０は、電子機器制御部９００の全体の制御を司るもので、メモリ９５０に記憶される本実施形態に係る各種の動作を行うためのコードから構成される制御プログラム９５１を実行することにより、電子機器制御部９００が提供する各種機能を実現する。また情報処理実行部９４０は、ユーザに選択されたアイコン６２１に対応するプログラムを実行する。なお、アイコン６３１に対応するプログラムも図４においては制御プログラム９５１として表現されている。つまり図４に示す制御プログラム９５１は、一つ以上の様々なプログラムを便宜的に総括的に表したものである。 The information processing execution unit 940 is responsible for overall control of the electronic device control unit 900, and executes a control program 951 configured with codes for performing various operations according to the present embodiment stored in the memory 950. Thus, various functions provided by the electronic device control unit 900 are realized. The information processing execution unit 940 executes a program corresponding to the icon 621 selected by the user. Note that the program corresponding to the icon 631 is also expressed as a control program 951 in FIG. That is, the control program 951 shown in FIG. 4 is a comprehensive representation of one or more various programs for convenience.
　メモリ９５０は、例えば半導体記憶装置やハードディスク装置により構成される物理的な記憶領域を提供する装置であり、図４に示す例では、制御プログラム９５１、音楽データ９５２、アイコン管理テーブル９５３を記憶している。 The memory 950 is a device that provides a physical storage area composed of, for example, a semiconductor storage device or a hard disk device. In the example shown in FIG. 4, the control program 951, music data 952, and icon management table 953 are stored. Yes.
　機能特定部９４３は、ユーザが選択したアイコン６２１を特定する。具体的には、機能特定部９４３は、ユーザがペン１０００の先端をパネル部６１０上のアイコン６２１の表示領域に接触あるいは近接させた場合に、送受信制御部８２０から取得したペン１０００の位置と、アイコン管理テーブル９５３と、を用いて、ユーザが選択したアイコン６２１を特定する。 The function specifying unit 943 specifies the icon 621 selected by the user. Specifically, the function specifying unit 943 displays the position of the pen 1000 acquired from the transmission / reception control unit 820 when the user brings the tip of the pen 1000 into contact with or close to the display area of the icon 621 on the panel unit 610. The icon 621 selected by the user is specified using the icon management table 953.
　アイコン管理テーブル９５３は、ＬＣＤ部６２０に表示されているアイコン６２１の位置を示す情報と、アイコン６２１の識別情報と、を対応付けて記憶したテーブルである。アイコン管理テーブル９５３を図１２に示す。 The icon management table 953 is a table in which information indicating the position of the icon 621 displayed on the LCD unit 620 and identification information of the icon 621 are stored in association with each other. An icon management table 953 is shown in FIG.
　ユーザが選択したアイコン６２１が機能特定部９４３によって特定されると、情報処理実行部９４０は、情報処理の実行指示の入力を契機に、このアイコン６２１に対応づけられているプログラムの実行を開始する。 When the icon 621 selected by the user is specified by the function specifying unit 943, the information processing execution unit 940 starts executing the program associated with the icon 621 in response to an input of an information processing execution instruction. .
　具体的には、本実施形態に係る情報処理実行部９４０は、ユーザが選択したアイコン６２１が機能特定部９４３によって特定されている状態で、ＤＳＰ９３０からダブルクリック信号あるいはシングルクリック信号を取得すると、このダブルクリック信号あるいはシングルクリック信号を情報処理の実行指示と解釈して、アイコン６２１に対応づけられているプログラムの実行を開始する。 Specifically, when the information processing execution unit 940 according to the present embodiment acquires a double-click signal or a single-click signal from the DSP 930 while the icon 621 selected by the user is specified by the function specifying unit 943, The double click signal or the single click signal is interpreted as an information processing execution instruction, and the execution of the program associated with the icon 621 is started.
　なおダブルクリック信号を情報処理の実行指示と解釈するかシングルクリック信号を情報処理の実行指示と解釈するかは、電子機器６００に対して所定の設定入力を行うことにより選択することが可能である。 Whether the double-click signal is interpreted as an information processing execution instruction or the single click signal is interpreted as an information processing execution instruction can be selected by inputting predetermined settings to the electronic device 600. .
　またダブルクリック信号あるいはシングルクリック信号を、情報処理の実行指示と解釈しないような設定を行うことも可能である。この場合電子機器６００は、電子機器６００が備える別途のスイッチやセンサ（不図示）へのユーザによる操作入力や、ＬＣＤ部６２０上に表示されたアイコン６２１へのペン１０００を用いた操作入力等を、情報処理の実行指示と解釈する。 It is also possible to make settings so that a double-click signal or single-click signal is not interpreted as an information processing execution instruction. In this case, the electronic device 600 performs an operation input by a user to a separate switch or sensor (not shown) provided in the electronic device 600, an operation input using the pen 1000 to the icon 621 displayed on the LCD unit 620, or the like. This is interpreted as an information processing execution instruction.
　ダブルクリック信号あるいはシングルクリック信号は、ＤＳＰ９３０のクリック判定部９３２から情報処理実行部９４０に送信されてくる。 The double click signal or single click signal is transmitted from the click determination unit 932 of the DSP 930 to the information processing execution unit 940.
　クリック判定部９３２は、マイク９１０を用いて外部の音声を取得し、この音声が所定パターンの音声であるか否かを解析している。そしてクリック判定部９３２は、この音声が所定パターンの音声であることを検知した場合には、ユーザが電子機器６００に対してダブルクリックあるいはシングルクリックの操作入力を行ったと判定し、上記のダブルクリック信号あるいはシングルクリック信号を情報処理実行部９４０に送信する。 The click determination unit 932 acquires external sound using the microphone 910 and analyzes whether or not the sound is a sound of a predetermined pattern. When the click determination unit 932 detects that the sound is a sound having a predetermined pattern, the click determination unit 932 determines that the user has performed a double-click or single-click operation input on the electronic device 600, and the double-click is performed. A signal or a single click signal is transmitted to the information processing execution unit 940.
　このような態様により、本実施形態に係る電子機器６００は、より効率的な電子機器６００への操作入力を行うことが可能になる。つまり、本実施形態に係る電子機器６００のユーザは、マウスではなくペン１０００を用いて電子機器６００への情報入力を行っているが、ペン１０００は、そのサイズや形状の特徴から、クリック入力を行うためのスイッチやボタンを設けるスペースや位置が制約される。 According to such an aspect, the electronic device 600 according to the present embodiment can perform operation input to the electronic device 600 more efficiently. That is, the user of the electronic device 600 according to the present embodiment inputs information to the electronic device 600 using the pen 1000 instead of the mouse, but the pen 1000 performs a click input based on the size and shape characteristics. Spaces and positions for providing switches and buttons for performing are restricted.
　例えば、ペン１０００の先端とは反対側の端部あるいはその近傍にクリック用のスイッチを設けた場合には、ユーザはクリック入力のたびにペン１０００を持ちかえなければならず、クリック操作を頻繁に行うには不便である。あるいは、ペン１０００を持ちかえずにクリック入力を行うために、ユーザの指や手のひらが触れる部分にスイッチを設けてしまうと、誤操作が生じやすくなる可能性がある。 For example, when a click switch is provided at the end opposite to the tip of the pen 1000 or in the vicinity thereof, the user must hold the pen 1000 each time a click is input, and the click operation is frequently performed. Inconvenient to do. Alternatively, in order to perform a click input without holding the pen 1000, if a switch is provided at a portion where the user's finger or palm touches, an erroneous operation may be likely to occur.
　あるいは、ペン１０００に対して所定の方向から一定の押圧力を加えることによりペン１０００の形状を変化させ、ペン１０００の内部に設けた圧力センサやスイッチなどでこの形状変化を検知することで、クリック入力を可能にすることも考えられるが、このようなペン１０００を変形させる方式では、ペン１０００が故障しやすくなり、耐久性を低下させる可能性がある。 Alternatively, by applying a constant pressing force to the pen 1000 from a predetermined direction, the shape of the pen 1000 is changed, and this change in shape is detected by a pressure sensor, a switch, or the like provided in the pen 1000. Although it is conceivable to enable input, such a method of deforming the pen 1000 may cause the pen 1000 to break down and possibly reduce durability.
　あるいは、例えばＬＣＤ部６２０にクリック入力用のアイコン６２１を表示し、このアイコン６２１をペン１０００で選択することでクリック入力を行うことも考えられるが、この場合は、クリック入力用のアイコン６２１がＬＣＤ部６２０において一定の表示面積を占有することになる上、他のアイコン６２１と間違えやすく誤操作も生じやすい。さらに、シングルクリックとダブルクリックの区別をするのも困難である。 Alternatively, for example, a click input icon 621 may be displayed on the LCD unit 620, and the click input may be performed by selecting the icon 621 with the pen 1000. In this case, the click input icon 621 is the LCD The unit 620 occupies a certain display area, and is easily mistaken for other icons 621, and erroneous operations are likely to occur. Furthermore, it is difficult to distinguish between single clicks and double clicks.
　本実施形態に係る電子機器６００によれば、例えばマイク９１０の近傍でパネル部６１０をペン１０００でたたいて上記の所定パターンの音声を発生させるだけで、この時のペン１０００と電子機器６００との接触音からクリック入力を行うことが可能となるため、ユーザは電子機器６００へのシングルクリック操作あるいはダブルクリック操作を容易に行うことが可能となり、作業効率を向上させることができる。このため、例えば手指に障害のある人が口にペン１０００をくわえた状態であっても、容易にクリック入力を行うことも可能となる。 According to the electronic device 600 according to the present embodiment, for example, by simply striking the panel unit 610 with the pen 1000 in the vicinity of the microphone 910 and generating the sound of the predetermined pattern, the pen 1000 and the electronic device 600 at this time Therefore, the user can easily perform a single click operation or a double click operation on the electronic device 600, and work efficiency can be improved. For this reason, for example, even when a person with a handicap finger holds the pen 1000 in the mouth, it is possible to easily perform a click input.
　さらに言えば、電子機器６００をペン１０００でたたく必要はなく、指でたたいても良いし、他の器具でたたいても良い。このような態様によれば、例えば右手に持ったペン１０００を使ってパネル部６１０への文字入力などの情報入力を行いつつ、左手で指や他の道具を使って電子機器６００あるいは机などのマイク９１０の近傍をたたくことで、クリック入力を行うようなことも可能となる。 Furthermore, there is no need to tap the electronic device 600 with the pen 1000, and it may be hit with a finger or another instrument. According to such an aspect, for example, while inputting information such as character input to the panel unit 610 using the pen 1000 held in the right hand, the electronic device 600 or the desk or the like using a finger or another tool with the left hand. It is possible to perform a click input by hitting the vicinity of the microphone 910.
　また、本実施形態に係る電子機器６００によれば、上述したようなクリック入力用のスイッチやセンサをペン１０００に設ける必要をなくせるため、ペン１０００の耐久性を向上させることも可能となる。 Further, according to the electronic apparatus 600 according to the present embodiment, since it is not necessary to provide the pen 1000 with a switch or sensor for click input as described above, the durability of the pen 1000 can be improved.
　次に、クリック判定部９３２が、ダブルクリックあるいはシングルクリックの入力がなされたか否かの判定を行う際の処理の流れを、図５及び図６に示すフローチャートを参照しながら説明する。 Next, the flow of processing when the click determination unit 932 determines whether or not a double-click or single-click input has been made will be described with reference to the flowcharts shown in FIGS.
　まずクリック判定部９３２は、マイク９１０によって所定音量以上の音声が検知されたか否かを判定する（S1000）。 First, the click determination unit 932 determines whether or not a sound with a predetermined volume or higher is detected by the microphone 910 (S1000).
　クリック判定部９３２は、所定音量以上の音声が入力されたことを検知すると、電子機器６００が稼働状態（いわゆる電源オン状態）であるか、非稼働状態（いわゆる電源オフ状態）であるかを判定する（S1010）。ＤＳＰ９３０内の図示しない不揮発性メモリには、電子機器６００が稼働状態であるか非稼働状態であるかを示す情報（稼働フラグ９３３）が記憶されており、クリック判定部９３２はこの稼働フラグ９３３を参照することにより、電子機器６００が稼働状態であるか非稼働状態であるかを判定することができる。 When the click determination unit 932 detects that a sound having a predetermined volume or more is input, the click determination unit 932 determines whether the electronic device 600 is in an operating state (so-called power-on state) or in a non-operating state (so-called power-off state). (S1010). Information (operation flag 933) indicating whether the electronic device 600 is in an operating state or a non-operating state is stored in a nonvolatile memory (not shown) in the DSP 930, and the click determination unit 932 displays the operation flag 933. By referencing, it can be determined whether the electronic device 600 is in an operating state or a non-operating state.
　なお、稼働フラグ９３３は、電子機器６００が稼働状態であるか非稼働状態であるかに応じて以下のように情報処理実行部９４０によって随時更新される。 The operation flag 933 is updated as needed by the information processing execution unit 940 as follows depending on whether the electronic device 600 is in an operating state or a non-operating state.
　つまり情報処理実行部９４０は、電子機器６００の機能を停止させるための指示入力（アイコン６２１の選択を通じた入力や、電子機器６００に設けられたスイッチやセンサ（不図示）を操作することによる入力など）を受け付けると（いわゆる電源オフ）、電子機器６００の機能を停止させるための情報処理を実行する。そして情報処理実行部９４０は、所定の手順に従って電子機器６００内の各構成要素の機能を順次停止させていき、ＤＳＰ９３０内の稼働フラグ９３３を非稼働状態に更新した後、情報処理実行部９４０の機能も停止させる。 That is, the information processing execution unit 940 inputs an instruction to stop the function of the electronic device 600 (input through selection of the icon 621 or input by operating a switch or sensor (not shown) provided in the electronic device 600). Etc.) (so-called power off), information processing for stopping the function of electronic device 600 is executed. Then, the information processing execution unit 940 sequentially stops the function of each component in the electronic device 600 according to a predetermined procedure, updates the operation flag 933 in the DSP 930 to the non-operation state, and then performs the processing of the information processing execution unit 940. The function is also stopped.
　一方で、電子機器６００が非稼働状態にある場合に電子機器６００に所定音量以上の音声が入力されると、クリック判定部９３２は、情報処理実行部９４０に対してＷＡＫＥＵＰ信号を出力する（S1020）。 On the other hand, when the electronic device 600 is in a non-operating state and the sound of a predetermined volume or more is input to the electronic device 600, the click determination unit 932 outputs a WAKEUP signal to the information processing execution unit 940 (S1020). ).
　情報処理実行部９４０は、ＷＡＫＥＵＰ信号が入力されると、所定の手順に従って電子機器制御部９００及び電子機器６００内の各構成要素の機能を順次開始させていく。このとき情報処理実行部９４０は、ＤＳＰ９３０内の稼働フラグ９３３を稼働状態に更新する。 When the WAKEUP signal is input, the information processing execution unit 940 sequentially starts the functions of each component in the electronic device control unit 900 and the electronic device 600 according to a predetermined procedure. At this time, the information processing execution unit 940 updates the operation flag 933 in the DSP 930 to the operation state.
　S1000において電子機器６００に所定音量以上の音声が入力された際に、電子機器６００が稼働状態であった場合には、クリック判定部９３２は、ダブルクリック判定時間（所定時間）以内に、所定音量未満の音声が所定音量以上に２回以上変化するような音声を検知したか否かを判定する（S1030）。 When the electronic device 600 is in an operating state when a sound of a predetermined volume or higher is input to the electronic device 600 in S1000, the click determination unit 932 has a predetermined volume within a double-click determination time (predetermined time). It is determined whether or not a voice has been detected such that a voice less than 2 changes more than a predetermined volume (S1030).
　クリック判定部９３２は、ダブルクリック判定時間以内に所定音量未満の音声が所定音量以上に２回以上変化するような音声を検知した場合には、電子機器６００にダブルクリックが入力されたと判定し、情報処理実行部９４０に対してダブルクリック信号を出力する（S1040）。 The click determination unit 932 determines that a double click has been input to the electronic device 600 when detecting a sound in which a sound with a volume lower than a predetermined volume changes twice or more above a predetermined volume within a double click determination time, A double click signal is output to the information processing execution unit 940 (S1040).
　一方、ダブルクリック判定時間以内に所定音量未満の音声が所定音量以上に２回以上変化するような音声を検知しなかった場合には、クリック判定部９３２は、電子機器６００にシングルクリックが入力されたと判定し、情報処理実行部９４０に対してシングルクリック信号を出力する（S1050）。 On the other hand, if no sound is detected in which the sound below the predetermined volume changes twice or more above the predetermined sound volume within the double-click determination time, the click determination unit 932 inputs a single click to the electronic device 600. It is determined that the single click signal is output to the information processing execution unit 940 (S1050).
　情報処理実行部９４０は、ダブルクリック信号あるいはシングルクリック信号が入力されると、所定の設定情報に従って、ダブルクリック信号あるいはシングルクリック信号が入力された場合の所定の情報処理を実行する。例えば、ユーザによって選択されたアイコン６２１に対応づけられているプログラムの実行を開始する。 When the double click signal or the single click signal is input, the information processing execution unit 940 executes predetermined information processing when the double click signal or the single click signal is input according to the predetermined setting information. For example, the execution of the program associated with the icon 621 selected by the user is started.
　本実施形態に係る電子機器６００は、このような態様により、より効率的な操作入力を行うことを可能にしている。 The electronic device 600 according to the present embodiment can perform more efficient operation input in this manner.
　なおクリック判定部９３２は、S1000において、上述したダブルクリックの入力がなされたか否かを検知するようにしてもよい。この場合クリック判定部９３２は、電子機器６００が非稼働状態にある場合に電子機器６００にダブルクリックが入力されると、情報処理実行部９４０に対してＷＡＫＥＵＰ信号を出力する。 Note that the click determination unit 932 may detect whether or not the above-described double-click input has been made in S1000. In this case, the click determination unit 932 outputs a WAKEUP signal to the information processing execution unit 940 when a double click is input to the electronic device 600 when the electronic device 600 is in a non-operating state.
　また本実施形態に係るクリック判定部９３２は、上記のダブルクリック判定時間の長さを動的に設定することができる。例えば、クリック判定部９３２は、電子機器６００が音楽を再生中の場合には、再生中の音楽のテンポ（速度）に応じてダブルクリック判定時間の長さを変えるようにしても良い。 Also, the click determination unit 932 according to the present embodiment can dynamically set the length of the double click determination time. For example, when the electronic device 600 is playing music, the click determination unit 932 may change the length of the double-click determination time according to the tempo (speed) of the music being played.
　通常、コンピュータへのクリック入力がシングルクリックであるかダブルクリックであるかを判別するために設定されるダブルクリック判定時間は、予めユーザにより設定された時間に固定されたままであるが、ユーザは、その時の心理状態によって、時間を速く感じたり遅く感じたりする。例えば、ゆったりとした音楽を聴いている場合には、ユーザの時間の感じ方は一般的にゆっくりになると考えられる。そのため、例えばユーザはダブルクリックを行ったつもりであっても、コンピュータにはシングルクリックであると判定されてしまう場合もある。 Usually, the double-click determination time set to determine whether the click input to the computer is a single click or a double click remains fixed at a time set in advance by the user. Depending on the psychological state at that time, time may be felt faster or slower. For example, when listening to relaxed music, the user's feeling of time is generally considered to be slow. Therefore, for example, even if the user intends to double-click, the computer may determine that it is a single click.
　本実施形態に係る電子機器６００によれば、以下に記すように、再生中の音楽のテンポ（速度）に応じてダブルクリック判定時間の長さを変えることができるため、ダブルクリックあるいはシングルクリックの誤入力を防止でき、より効率的な操作入力が可能となる。 According to the electronic device 600 according to the present embodiment, as described below, the length of the double-click determination time can be changed according to the tempo (speed) of the music being played, so that double-click or single-click Incorrect input can be prevented, and more efficient operation input becomes possible.
　また、クリック判定部９３２は、図５のS1000やS1030において外部の音声の音量が所定音量を超えたか否かを判定する際の判定基準（閾値）を、再生中の音楽の音量に応じて動的に設定するようにしても良い。この場合、クリック判定部９３２は、再生中の音楽の音量が大きいほど判定基準を大きくするとよい。 In addition, the click determination unit 932 moves a determination criterion (threshold) for determining whether or not the volume of the external sound exceeds a predetermined volume in S1000 and S1030 of FIG. 5 according to the volume of the music being played. You may make it set up automatically. In this case, the click determination unit 932 may increase the determination criterion as the volume of the music being played is increased.
　このような態様によっても音楽を視聴中のユーザの心理状態に適合したクリック入力が可能となるため、より効率的なクリック入力が可能となる。 Also in this manner, click input suitable for the psychological state of the user who is viewing the music is possible, and thus more efficient click input is possible.
　音楽制御部９４１は、電子機器６００が音楽を再生する場合の制御を司る。音楽制御部９４１は、例えば音楽を再生させる旨のアイコン６２１がユーザに選択され、上記の音声によるダブルクリックあるいはシングルクリックが入力された場合に、メモリ９５０から再生させるべき音楽の音楽データ９５２を読み出して、ＤＳＰ９３０に転送する。そしてＤＳＰ９３０のデータ処理部９３１は、音楽制御部９４１から転送された音楽データ９５２から音楽を復元して、スピーカ９２０から出力する。 The music control unit 941 manages control when the electronic device 600 reproduces music. The music control unit 941 reads out music data 952 of music to be played back from the memory 950 when, for example, an icon 621 for playing music is selected by the user and a double click or single click with the above sound is input. To the DSP 930. The data processing unit 931 of the DSP 930 restores music from the music data 952 transferred from the music control unit 941 and outputs the music from the speaker 920.
　また音楽制御部９４１は録音を行うことも可能である。この場合、音楽制御部９４１は、ＤＳＰ９３０に対して、マイク９１０によって検出される電子機器６００の外部の音声を音楽データ９５２に変換させ、メモリ９５０に記録する。 Also, the music control unit 941 can perform recording. In this case, the music control unit 941 causes the DSP 930 to convert audio outside the electronic device 600 detected by the microphone 910 into music data 952 and record the music data 952 in the memory 950.
　音楽データ９５２は、音楽を再生するためのデータであり、ＷＭＡ、ＭＰ３、ＡＡＣ等の様々な形式で記録されるデータである。この音楽データ９５２は、電子機器６００と通信可能に接続される他の情報機器（例えば他の電子機器や各種の記録媒体など）から通信装置（音楽データ取得部）９６０を通じて取得することが可能である。あるいは、マイク９２０によって検出された外部の音声を、ＤＳＰ９３０が音楽データ８５２に変換して情報処理実行部９４０に転送し、メモリ９５０に記録するようにして取得することも可能である。 The music data 952 is data for reproducing music, and is data recorded in various formats such as WMA, MP3, AAC and the like. The music data 952 can be acquired from another information device (for example, another electronic device or various recording media) that is communicably connected to the electronic device 600 through the communication device (music data acquisition unit) 960. is there. Alternatively, the external sound detected by the microphone 920 can be acquired by the DSP 930 converting it into music data 852, transferring it to the information processing execution unit 940, and recording it in the memory 950.
　音楽分析部９４２は、音楽制御部９４１が再生中の音楽の音楽データ９５２を分析し、音楽の特徴を表す特徴情報を抽出する。抽出される特徴情報には、例えば音楽のテンポや音量を示す情報が含まれ、さらには、音楽のジャンル（ロック、クラシック等）を示す情報や、調を示す情報が含まれてもよい。 The music analysis unit 942 analyzes the music data 952 of the music being played back by the music control unit 941 and extracts feature information representing the features of the music. The extracted feature information includes, for example, information indicating the tempo and volume of the music, and may further include information indicating the genre of music (rock, classic, etc.) and information indicating the key.
　そして音楽分析部９４２は、再生中の音楽の特徴情報をクリック判定部９３２に通知する。 Then, the music analysis unit 942 notifies the click determination unit 932 of the characteristic information of the music being played.
　なお、音楽分析部９４２は、再生中の音楽データ９５２を分析して特徴情報を抽出するのみならず、メモリ９５０に記憶されている音楽データ９５２をあらかじめ分析して特徴情報を抽出しておき、再生時にこの特徴情報をクリック判定部９３２に通知するようにしても良い。このような態様により、音楽を再生中の情報処理実行部９４０の負荷を軽減することが可能となる。 Note that the music analysis unit 942 not only analyzes the music data 952 being played and extracts the feature information, but also analyzes the music data 952 stored in the memory 950 in advance to extract the feature information. You may make it notify this characteristic information to the click determination part 932 at the time of reproduction | regeneration. With such an aspect, it is possible to reduce the load on the information processing execution unit 940 that is playing music.
　クリック判定部９３２は、音楽の特徴情報に記述されている再生中の音楽のテンポを示す情報を用いて、ダブルクリック判定時間を更新する。例えばクリック判定部９３２は、音楽のテンポとダブルクリック判定時間とを対応付けたテーブル（不図示）をあらかじめ記憶しておき、このテーブルを参照することにより、再生中の音楽のテンポに合わせたダブルクリック時間を設定する。例えば、クリック判定部９３２は、音楽のテンポがより速いほど、ダブルクリック判定時間が短くなるように調整する。 The click determination unit 932 updates the double-click determination time using information indicating the tempo of the music being played described in the music feature information. For example, the click determination unit 932 stores in advance a table (not shown) in which music tempo and double click determination time are associated with each other, and by referring to this table, the double determination according to the tempo of the music being played back is performed. Set the click time. For example, the click determination unit 932 adjusts the double click determination time to be shorter as the music tempo is faster.
　また、このテーブルをユーザが自ら設定できるようにしても良い。このような態様によれば、ユーザは自分の好みに合わせたクリック判定時間を自由に設定することが可能となり、より効率的なクリック入力が可能となる。 Also, this table may be set by the user himself. According to such an aspect, the user can freely set the click determination time according to his / her preference, and more efficient click input can be performed.
　クリック判定部９３２がダブルクリック判定時間や音量の判定基準を動的に設定する際の処理の流れを図６のフローチャートに示す。 The flow of processing when the click determination unit 932 dynamically sets the double click determination time and the volume determination criterion is shown in the flowchart of FIG.
　まずクリック判定部９３２は、電子機器６００が音楽を再生中であるか否かを判定する（S2000）。そして電子機器６００が音楽を再生中である場合には、クリック判定部９３２は、音楽分析部９４２によって抽出された特徴情報を取得し、この特徴情報に記述されている音楽のテンポを示す情報に基づいて（S2010）、ダブルクリック判定時間を動的に設定する（S2020）。 First, the click determination unit 932 determines whether or not the electronic device 600 is playing music (S2000). When the electronic device 600 is playing music, the click determination unit 932 acquires the feature information extracted by the music analysis unit 942 and uses the information indicating the music tempo described in the feature information. Based on this (S2010), the double-click determination time is dynamically set (S2020).
　またクリック判定部９３２は、この特徴情報に記述されている音楽の音量を示す情報に基づいて（S2030）、外部の音声の音量が所定音量を超えたか否かを判定する際の判定基準（閾値）を動的に設定する（S2040）。 Also, the click determination unit 932 determines a criterion (threshold value) when determining whether or not the volume of the external sound exceeds the predetermined volume based on the information indicating the volume of the music described in the feature information (S2030). ) Is dynamically set (S2040).
　このような態様によって、ユーザが視聴中の音楽の速度や音量によって、ユーザが入力するダブルクリック操作の検知感度やダブルクリックかシングルクリックかの判定時間を動的に設定することができ、より効率的なクリック入力が可能となる。 In this manner, the detection sensitivity of the double-click operation input by the user and the determination time of double-click or single-click can be dynamically set according to the speed and volume of the music being watched by the user. Click input is possible.
　なおクリック判定部９３２は、再生中の音楽のジャンルや調に応じて、ダブルクリック判定時間を動的に設定しても良い。例えばクラシックの場合はダブルクリック判定時間が長めになるように調整し、ロックの場合は短めになるように調整しても良い。あるいは、音楽の調が長調の場合は、ダブルクリック判定時間が短めになるように調整し、短調の場合は長めになるように調整しても良い。 Note that the click determination unit 932 may dynamically set the double-click determination time according to the genre and key of the music being played. For example, in the case of classic, the double click determination time may be adjusted to be longer, and in the case of lock, it may be adjusted to be shorter. Alternatively, when the key of the music is a major key, the double click determination time may be adjusted to be shorter, and when the key is a minor key, it may be adjusted to be longer.
　なお、上記の実施形態では、ユーザがＬＣＤ部６２０に表示されているアイコン６２１をペン１０００で選択してからシングルクリックあるいはダブルクリックの入力を行うことで、電子機器６００がアイコン６２１により特定される情報処理を実行する場合を説明したが、アイコン６２１による機能の選択はクリック入力の後でもよい。 In the above embodiment, the electronic device 600 is specified by the icon 621 when the user selects the icon 621 displayed on the LCD unit 620 with the pen 1000 and performs a single click or double click input. Although the case where information processing is executed has been described, the selection of a function using the icon 621 may be performed after a click input.
　以上、本実施形態に係る電子機器６００について説明したが、本実施形態に係る電子機器６００によれば、所定パターンの音声を検知した場合に情報処理の実行が行われるように構成されているため、この情報処理を実行するための操作入力を効率的に行うことが可能になる。 Although the electronic device 600 according to the present embodiment has been described above, the electronic device 600 according to the present embodiment is configured such that information processing is performed when a predetermined pattern of sound is detected. Therefore, it is possible to efficiently perform an operation input for executing this information processing.
　また本実施形態に係る電子機器６００は、情報処理を実行する機能を停止するための情報処理を実行した場合にこの機能を停止し、この機能が停止した状態で所定パターンの音声を検知した場合にこの機能を再開する。 In addition, when the electronic device 600 according to the present embodiment executes the information processing for stopping the function for executing the information processing, the electronic device 600 stops the function, and detects the sound of the predetermined pattern with the function stopped. To resume this function.
　このような態様によって、音声入力による電子機器６００の起動が可能になり、ユーザにとってより使いやすい電子機器６００を提供することが可能となる。 In this manner, the electronic device 600 can be activated by voice input, and the electronic device 600 that is easier to use for the user can be provided.
　また本実施形態に係る電子機器６００は、所定時間内に、所定音量未満の音声が所定音量以上に２回以上変化するような音声を、上記所定パターンの音声として検知する。このような態様によって、所謂ダブルクリックの入力を音声によって行うことが可能となるため、ユーザにとってより使いやすく効率的な操作入力が可能となる。 In addition, the electronic apparatus 600 according to the present embodiment detects a sound in which a sound with a sound volume lower than a predetermined sound volume changes twice or more within a predetermined time as a sound with the predetermined pattern. In this manner, so-called double-click input can be performed by voice, so that the user can use the operation input more easily and efficiently.
　また本実施形態に係る電子機器６００は、再生中の音楽の速度や音量に応じて、ユーザが入力するダブルクリック操作の検知感度やダブルクリックかシングルクリックかの判定時間を動的に設定する。このような態様によってより効率的なクリック入力が可能となる。 Also, the electronic device 600 according to the present embodiment dynamically sets the detection sensitivity of the double-click operation input by the user and the determination time of double-click or single-click according to the speed and volume of the music being played. Such an aspect enables more efficient click input.
　また上述したように本実施形態に係る電子機器６００においては、パネル部６１０の透明度を低下させないようにできるため、図１に示したように、パネル部６１０を、ＬＣＤ部６２０の外側（ＬＣＤ部６２０が本体構成部６３０に向かう側の面とは反対側）の面に装着することが可能となる。 Further, as described above, in the electronic apparatus 600 according to the present embodiment, since the transparency of the panel unit 610 can be prevented from being lowered, the panel unit 610 is placed outside the LCD unit 620 (LCD unit) as shown in FIG. 620 can be attached to the surface on the side opposite to the surface facing the main body component 630.
　このため、ペン入力機能を想定していない一般的なＬＣＤパネルを改造することなくＬＣＤ部６２０として用いることが可能となり、コスト低減を図ることが可能となる。より詳細には、電波の不要輻射を防止するためにＬＣＤパネルの下面側に設けられている金属板（アルミ板）を取り外さずにそのままＬＣＤ部６２０として用いることが可能になる。 Therefore, a general LCD panel that does not assume a pen input function can be used as the LCD unit 620 without remodeling, and costs can be reduced. More specifically, it is possible to use the LCD unit 620 as it is without removing the metal plate (aluminum plate) provided on the lower surface side of the LCD panel in order to prevent unnecessary radiation of radio waves.
　なお上述した実施の形態は本発明の理解を容易にするためのものであり、本発明を限定して解釈するためのものではない。本発明はその趣旨を逸脱することなく変更、改良され得るとともに、本発明にはその等価物も含まれる。 The above-described embodiment is for facilitating understanding of the present invention, and is not intended to limit the present invention.
