Description

携帯電子機器及び携帯ユニットPortable electronic device and portable unit
　本発明は、スクリーンや壁面に画像を投影する画像投影部を有する携帯電子機器及び携帯ユニットに関する。 The present invention relates to a portable electronic device and a portable unit having an image projection unit that projects an image onto a screen or a wall surface.
　従来から、壁面やスクリーンに画像を投影する装置としては、いわゆるプロジェクタがある。このプロジェクタは、商用電源から電力が供給され、所定位置に固定した状態で使用される、いわゆる据え置き型の装置が主流である。この据え置き型のプロジェクタは、固定した状態で、一定箇所の壁面やスクリーンに画像を投影させる。 Conventionally, as a device for projecting an image on a wall surface or a screen, there is a so-called projector. This projector is mainly a so-called stationary apparatus that is supplied with power from a commercial power source and is used in a fixed state. This stationary projector projects an image on a fixed wall or screen in a fixed state.
　これに対して、近年、プロジェクタとして、小型で持ち運びが容易な携帯型のプロジェクタが提案されている。例えば、特許文献１には、上キャビネットと、下キャビネットと、上キャビネットおよび下キャビネットを互いに回動可能に接続するヒンジ部とを備え、レンズと光源とを有するプロジェクタが搭載されたプロジェクタ機能付携帯端末が記載されている。 In contrast, in recent years, portable projectors that are small and easy to carry have been proposed as projectors. For example, Patent Document 1 includes a projector-equipped mobile phone that includes an upper cabinet, a lower cabinet, a hinge portion that rotatably connects the upper cabinet and the lower cabinet, and a projector having a lens and a light source. The terminal is listed.
　このような、携帯型のプロジェクタでは、プロジェクタが画像を投影する領域を容易に変更することができる。つまり、光の照射方向を容易に変更することができる。そのため、意図せず人間に対して光を照射してしまう可能性がある。プロジェクタからは高輝度の光が照射されるため、プロジェクタから照射された光が近接した位置で直接目に入ると非常にまぶしい。 In such a portable projector, the area on which the projector projects an image can be easily changed. That is, the light irradiation direction can be easily changed. For this reason, there is a possibility of unintentionally irradiating a person with light. Since high-intensity light is emitted from the projector, it is very dazzling when the light emitted from the projector enters the eyes directly at a close position.
　この点に対しては、例えば特許文献２に、投影データを投影する投影部と、当該端末の状態を検出する検知部と、前記検知部によって検出された状態に変化が生じたか否かを判断する動き判定部と、投影データを前記投影部に送る制御部と、を備え、前記制御部は、前記動き判定部が当該端末の状態に変化が生じたと判断したときには、投射する光量を制御する制御データを前記投影部に伝送することにより、投射光領域に人間が入ったときに光量を調節することができる投影機能付携帯通信端末が記載されている。 For this point, for example, in Patent Document 2, it is determined whether or not a change has occurred in the projection unit that projects projection data, the detection unit that detects the state of the terminal, and the state detected by the detection unit. And a control unit that sends projection data to the projection unit, and the control unit controls the amount of light to be projected when the motion determination unit determines that the state of the terminal has changed. A portable communication terminal with a projection function is described in which the amount of light can be adjusted when a person enters the projection light area by transmitting control data to the projection unit.

　特許文献２に記載されているように、端末の状態が変化したら、投影部から出力される光の光量を低減するまたは出力を停止することで、操作者が端末を操作している間は、人間の目に直接光が入射する可能性及びまぶしい思いをさせる可能性を低くすることができる。 As described in Patent Document 2, when the state of the terminal changes, while the operator is operating the terminal by reducing the amount of light output from the projection unit or stopping the output, It is possible to reduce the possibility of direct light incident on human eyes and the possibility of dazzling.
　ここで、携帯型のプロジェクタでは、基本的に操作部と投影部とが一体化されることになる。そのため、表示画像を変更するためには、端末を操作する必要があるが、操作を行う度に投影が停止されたり光量が低減されたりすると、必要以上に出力が制限されることになり、表示させたい場合も表示させることができなくなる。また、携帯型のプロジェクタ（携帯電子機器）では、操作者が手に持っている状態で使用することもあるが、特許文献２に記載の装置では、操作者が手に持っている状態では、通常の光量で画像を投影することが困難である。 Here, in a portable projector, the operation unit and the projection unit are basically integrated. Therefore, in order to change the display image, it is necessary to operate the terminal, but if the projection is stopped or the amount of light is reduced each time the operation is performed, the output will be restricted more than necessary, and the display will be It is not possible to display even if you want to. Moreover, in a portable projector (portable electronic device), the operator may use it in the state of being held in the hand, but in the apparatus described in Patent Document 2, in the state of being held in the hand of the operator, It is difficult to project an image with a normal amount of light.

In addition to the display 12, the display unit 32 may provide a sub display at a position exposed to the outside even when the housing is closed, for example.
　プロジェクタ３４は、画像を投影する画像投影機構であり、上述したように、筐体１１の上面に画像を投影する光射出部３４ａが設けられている。ここで、図３は、図１に示す携帯電子機器で画像を表示させている状態を示す説明図である。携帯電子機器１０は、プロジェクタ３４の光射出部３４ａから画像を投影する、つまり画像を構成する光を射出することで、図３に示すように、筐体１１の上面に対向する面にある壁面、スクリーン等のうち、一定の領域（投影領域）に画像を投影することができる。なお、プロジェクタ３４は、制御部２２により動作が制御され、制御部２２から送られる種々の映像、例えば映画、プレゼンテーション資料を投影し、投影領域に表示させる。 The projector 34 is an image projection mechanism that projects an image, and as described above, the light emitting unit 34 a that projects an image on the upper surface of the housing 11 is provided. Here, FIG. 3 is an explanatory view showing a state in which an image is displayed on the portable electronic device shown in FIG. The portable electronic device 10 projects an image from the light emitting unit 34a of the projector 34, that is, emits light constituting the image, so that the wall surface on the surface facing the upper surface of the housing 11 as shown in FIG. An image can be projected onto a certain area (projection area) of a screen or the like. The operation of the projector 34 is controlled by the control unit 22, and various images such as movies and presentation materials sent from the control unit 22 are projected and displayed on the projection area.
　プロジェクタ３４は、光源と、画像データに応じて、光源から射出された光を投影するか否かを切り換える光学系とで構成されている。例えば、プロジェクタ３４には、ハロゲンライトや、ＬＥＤ光源、ＬＤ光源を光源とし、ＬＣＤ（Liquid　Crystal　Display）や、ＤＭＤ（Digital　Micro-mirror　Device）を光学系とした構成のプロジェクタを用いることができる。この場合は、光学系を各画素に対応して投影領域の全面に配置し、光源から射出された光を画像に合わせて光学系をオンオフさせることで画像を投影領域の全面に投影させることができる。また、プロジェクタ３４には、レーザ光を光源とし、光源から射出された光を透過させるか否かを切り換える切り換え素子と、切り換え素子を通過した光をラスター走査させるミラーとで構成される光学系とした構成のプロジェクタを用いることもできる。この場合は、ミラーによってレーザ光から射出された光の角度を変えて、投影領域の全面に光源から照射された光を走査させることで、投影領域に画像を投影させることができる。 The projector 34 includes a light source and an optical system that switches whether to project the light emitted from the light source according to the image data. For example, a projector having a configuration in which a halogen light, an LED light source, or an LD light source is used as a light source, and an LCD (Liquid Crystal Display) or DMD (Digital Micro-mirror Device) is used as an optical system can be used as the projector 34. In this case, the optical system is arranged on the entire surface of the projection region corresponding to each pixel, and the image is projected on the entire surface of the projection region by turning on and off the optical system according to the light emitted from the light source in accordance with the image. it can. The projector 34 includes an optical system that includes a switching element that uses laser light as a light source and switches whether to transmit light emitted from the light source, and a mirror that performs raster scanning of light that has passed through the switching element. A projector having the above-described configuration can also be used. In this case, by changing the angle of the light emitted from the laser light by the mirror and scanning the light emitted from the light source over the entire projection area, an image can be projected onto the projection area.
　加速度センサ３６は、筐体１１に加わる加速度を検出する検出器である。加速度センサ３６として、種々の方法で加速度を検出する検出器を用いることができ、例えば、静電容量の変化や、ピエゾ抵抗の変化、相対位置の変化等で加速度を検出する検出器を用いることができる。加速度センサ３６は、操作者が筐体１１を振ったり、移動させたりする際に、筐体１１に作用する加速度を検出する。携帯電子機器１０は、基本的に以上のような構成である。 The acceleration sensor 36 is a detector that detects acceleration applied to the housing 11. As the acceleration sensor 36, a detector that detects acceleration by various methods can be used. For example, a detector that detects acceleration by a change in capacitance, a change in piezoresistance, a change in relative position, or the like is used. Can do. The acceleration sensor 36 detects an acceleration that acts on the housing 11 when the operator shakes or moves the housing 11. The portable electronic device 10 is basically configured as described above.
　次に、図４を用いて携帯電子機器１０の動作、具体的には、プロジェクタの制御動作について説明する。ここで、図４は、携帯電子機器の動作の一例を示すフロー図である。まず、携帯電子機器１０は、ステップＳ１２として通常の動作を行っている。ここで、通常の動作とは、例えば、待ち受け画像の表示や、通話動作等、プロジェクタ３４以外の機能が使用されている状態である。次に、携帯電子機器１０の制御部２２は、ステップＳ１４として、プロジェクタ３４を起動させる指示、つまり起動指示が入力されているかを判定する。制御部２２は、プロジェクタ３４の起動指示が入力されていない（Ｎｏ）と判定したら、ステップＳ１２に進み、通常動作を続ける。このように、制御部２２は、プロジェクタ３４の起動指示が入力されたことが検出されるまでステップＳ１２とステップＳ１４を繰り返す。 Next, the operation of the portable electronic device 10, specifically, the control operation of the projector will be described with reference to FIG. Here, FIG. 4 is a flowchart showing an example of the operation of the portable electronic device. First, the portable electronic device 10 performs a normal operation as step S12. Here, the normal operation is a state in which functions other than the projector 34, such as display of a standby image and a call operation, are used. Next, the control part 22 of the portable electronic device 10 determines whether the instruction | indication which starts the projector 34, ie, the starting instruction | indication, is input as step S14. If it is determined that the activation instruction for the projector 34 has not been input (No), the control unit 22 proceeds to step S12 and continues normal operation. As described above, the control unit 22 repeats Step S12 and Step S14 until it is detected that the activation instruction of the projector 34 has been input.
　次に、制御部２２は、ステップＳ１４でプロジェクタ起動指示が入力されている、つまり、起動指示あり（Ｙｅｓ）と判定したら、ステップＳ１６として、プロジェクタ３４を起動させる。また、制御部２２は、記憶部２４からプロジェクタ３４の動作を制御するためのタスクを読み出し、アプリケーションプログラムを起動させる。制御部２２は、ステップＳ１６でプロジェクタ３４を起動させたら、ステップＳ１８として、携帯モードが選択されたかを判定する。ここで、制御部２２は、プロジェクタ３４を駆動させるモードとして、操作者が携帯電子機器１０（筐体１１）を持っている状態でプロジェクタ３４を使用することを想定した携帯モード（第１のモード）と、操作者が携帯電子機器１０（筐体１１）を机や、台や、充電台に置いた状態でプロジェクタ３４を使用することを想定した据え置きモード（第２のモード）との２つのモードを有する。携帯モードと据え置きモードの制御方法は、以下で動作と共に説明する。なお、本実施形態では携帯モードと据え置きモードとは、操作者により選択される。なお、操作者が選択するタイミングとしては、制御部２２がステップＳ１８に進んだ段階で選択させるようにしても、プロジェクタ起動前の通常動作時に予め設定として選択させるようにしてもよい。 Next, when it is determined in step S14 that a projector activation instruction has been input, that is, there is an activation instruction (Yes), the control unit 22 activates the projector 34 in step S16. Further, the control unit 22 reads a task for controlling the operation of the projector 34 from the storage unit 24 and activates an application program. If the control part 22 starts the projector 34 by step S16, it will determine whether portable mode was selected as step S18. Here, the control unit 22 drives the projector 34 as a mode for driving the projector 34 in a portable mode (first mode) assuming that the operator uses the portable electronic device 10 (the casing 11). ) And a stationary mode (second mode) on the assumption that the operator uses the projector 34 in a state where the portable electronic device 10 (housing 11) is placed on a desk, table, or charging table. Has a mode. A method for controlling the portable mode and the stationary mode will be described below together with the operation. In the present embodiment, the portable mode and the stationary mode are selected by the operator. Note that the timing of selection by the operator may be selected at the stage where the control unit 22 has proceeded to step S18, or may be selected as a preset during normal operation before starting the projector.
　制御部２２は、ステップＳ１８で、携帯モードが選択されている（Ｙｅｓ）と判定したら、ステップＳ２０として、携帯モードを起動させる。制御部２２は、ステップＳ２０で携帯モードを起動させたら、ステップＳ２２として、専用キー１４が押されているかを判定する。制御部２２は、ステップＳ２２で専用キー１４が押されていない（Ｎｏ）と判定したら、ステップＳ２４として、画像を投影させない。つまり、プロジェクタ３４から光を射出させない。また、制御部２２は、ステップＳ２２で専用キー１４が押されている（Ｙｅｓ）と判定したら、ステップＳ２６として、プロジェクタ３４から画像を投影させる。つまり、プロジェクタ３４から光を射出させる。 If it is determined in step S18 that the mobile mode is selected (Yes), the control unit 22 activates the mobile mode as step S20. When the portable mode is activated in step S20, the control unit 22 determines whether the dedicated key 14 is pressed as step S22. If it is determined in step S22 that the dedicated key 14 is not pressed (No), the control unit 22 does not project an image in step S24. That is, no light is emitted from the projector 34. If it is determined in step S22 that the dedicated key 14 is pressed (Yes), the control unit 22 causes the projector 34 to project an image in step S26. That is, light is emitted from the projector 34.
　制御部２２は、ステップＳ２２またはステップＳ２４で画像を投影させるか否かを制御したら、ステップＳ２８として、一定時間が経過したかを判定する。制御部２２は、ステップＳ２８で一定時間が経過してない（Ｎｏ）と判定したら、ステップＳ２２に進み、一定時間が経過している（Ｙｅｓ）と判定したら、ステップＳ４０に進む。このように制御部２２は、一定時間が経過するまで、ステップＳ２２からステップＳ２８の動作を繰り返し、専用キー１４が押されているか押されていないかで、画像を投影するか投影しないかを切り換える。なお、本実施形態では、画像を投影するか投影しないかを切り換えたが、所定値以下の光強度で投影するか否かを切り換えてもよい。この場合は、専用キー１４が押されていない間は、所定値以下の光強度で投影し、専用キー１４が押されている間は、通常の光強度で投影するようにすればよい。 If the control part 22 controls whether an image is projected by step S22 or step S24, it will determine whether fixed time passed as step S28. If it is determined in step S28 that the predetermined time has not elapsed (No), the control unit 22 proceeds to step S22, and if it is determined that the predetermined time has elapsed (Yes), the control unit 22 proceeds to step S40. In this way, the control unit 22 repeats the operations from step S22 to step S28 until a predetermined time elapses, and switches whether to project an image or not depending on whether or not the dedicated key 14 is pressed. . In the present embodiment, whether to project an image or not is switched. However, whether to project at a light intensity of a predetermined value or less may be switched. In this case, while the dedicated key 14 is not pressed, projection is performed with a light intensity equal to or less than a predetermined value, and while the dedicated key 14 is pressed, projection is performed with normal light intensity.
　また、制御部２２は、ステップＳ１８で携帯モードが選択されていない（Ｎｏ）と判定したら、ステップＳ３０として、据え置きモードを起動する。制御部２２は、ステップＳ３０で据え置きモードを起動させたら、ステップＳ３２として、プロジェクタ３４から画像を投影させる。つまり、プロジェクタ３４から光を射出させる。制御部２２は、ステップＳ３２でプロジェクタ３４により画像を投影させたら、ステップＳ３４として、一定時間が経過したかを判定する。制御部２２は、ステップＳ３４で一定時間が経過してない（Ｎｏ）と判定したら、ステップＳ３２に進み、一定時間が経過している（Ｙｅｓ）と判定したら、ステップＳ４０に進む。このように制御部２２は、一定時間が経過するまで、ステップＳ３２とステップＳ３４の動作を繰り返し、プロジェクタ３４から画像を投影し続ける。 Further, when it is determined in step S18 that the portable mode is not selected (No), the control unit 22 activates the stationary mode as step S30. After starting the stationary mode in step S30, the control unit 22 projects an image from the projector 34 in step S32. That is, light is emitted from the projector 34. When the control unit 22 causes the projector 34 to project an image in step S32, the control unit 22 determines in step S34 whether a predetermined time has elapsed. If it is determined in step S34 that the predetermined time has not elapsed (No), the control unit 22 proceeds to step S32, and if it is determined that the predetermined time has elapsed (Yes), the control unit 22 proceeds to step S40. As described above, the control unit 22 repeats the operations of step S32 and step S34 until a predetermined time elapses, and continues to project an image from the projector 34.
　また、制御部２２は、ステップＳ２８またはステップＳ３４で一定時間が経過したら、ステップＳ４０として、プロジェクタ３４の駆動を終了させる指示、つまり、終了指示があるかを判定する。制御部２２は、ステップＳ４０でプロジェクタ終了指示がない（Ｎｏ）と判定したらステップＳ１８に進み、再び、選択されているモードを検出し、モードに基づいて、プロジェクタ３４の動作を制御する。つまり、プロジェクタ３４の駆動を停止するまで、上記動作を繰り返す。また、制御部２２が、ステップＳ４０で、プロジェクタ終了指示がある（Ｙｅｓ）と判定したら、ステップＳ４２として、プロジェクタ３４の駆動を終了し、通常動作に戻り処理を終了する。なお、制御部２２は、通常動作に戻ったら、再び、プロジェクタの起動指示が入力されているかを判定する。つまり、制御部２２は、図４に示すフロー図の動作を繰り返す。 Further, when a predetermined time has elapsed in step S28 or step S34, the control unit 22 determines in step S40 whether there is an instruction to end the driving of the projector 34, that is, an end instruction. If it is determined in step S40 that there is no projector termination instruction (No), control unit 22 proceeds to step S18, detects the selected mode again, and controls the operation of projector 34 based on the mode. That is, the above operation is repeated until the driving of the projector 34 is stopped. If the control unit 22 determines in step S40 that there is a projector termination instruction (Yes), in step S42, the driving of the projector 34 is terminated, the normal operation is returned, and the process is terminated. When the control unit 22 returns to the normal operation, the control unit 22 determines again whether a startup instruction for the projector is input. That is, the control unit 22 repeats the operation of the flowchart shown in FIG.
　以上のように、携帯電子機器１０は、携帯モードと据え置きモードの２つのモードを選択可能とし、携帯モードが選択されている場合は、専用キー１４が押されている場合のみプロジェクタ３４から画像を投影させ、据え置きモードが選択されている場合は、専用キー１４が押されているか否かにかかわらず、プロジェクタ３４から画像を投影させる。 As described above, the portable electronic device 10 can select two modes, the portable mode and the stationary mode. When the portable mode is selected, an image is displayed from the projector 34 only when the dedicated key 14 is pressed. When the stationary mode is selected, an image is projected from the projector 34 regardless of whether or not the dedicated key 14 is pressed.
　このように、操作者が手に持って使用する等、画像の投影位置、つまり光の照射位置が変化しやすい場合は、携帯モードを選択し、専用キー１４を押している場合のみ画像を投影するようにすることで、画像の投影領域に人間が入った場合にすぐに画像の投影を停止、つまり光の照射を停止することができる。特に、射出している光が人間の顔に照射された場合も、操作者は、専用キー１４を離すのみで、光の照射を停止できるため、人間にまぶしい思いをさせる可能性をより低くすることができる。また、操作者が不意に携帯電子機器を落としたりした場合も、光の照射が停止するため、落下時等、どの方向に光が照射されるかわからない時に光が照射される可能性を低減することができ、人間にまぶしい思いをさせる可能性をより少なくすることができる。また、人間にまぶしい思いをさせる可能性をより低くできるため、本実施形態のように専用キーが押されていない場合は光の射出を停止することが好ましいが、上述したように、専用キーが押されていない場合は、所定値以下の光強度で投影するようにする、つまり、射出させる光の光量を一定値以下とすることでも、人間にまぶしい思いをさせる可能性をより低くできる。 As described above, when the projection position of the image, that is, the light irradiation position is easily changed, such as when the operator holds it in his hand, the portable mode is selected, and the image is projected only when the dedicated key 14 is pressed. By doing so, when a person enters the image projection area, the projection of the image can be stopped immediately, that is, the light irradiation can be stopped. In particular, even when the emitted light is irradiated on the human face, the operator can stop the light irradiation simply by releasing the dedicated key 14, so that the possibility of making the person feel dazzling is further reduced. be able to. Also, if the operator unexpectedly drops the portable electronic device, the light irradiation stops, so the possibility of light irradiation when not knowing which direction the light is irradiated, such as when falling, is reduced. Can reduce the possibility of dazzling humans. Further, since it is possible to reduce the possibility of dazzling human beings, it is preferable to stop the light emission when the dedicated key is not pressed as in the present embodiment. If the light is not pressed, projection is performed with a light intensity equal to or less than a predetermined value, that is, the amount of light emitted is set to a certain value or less, so that the possibility of dazzling humans can be further reduced.
　また、従来のプロジェクタと同様に、携帯電子機器１０を机、いす、台に置いて使用する等、画像の投影位置が基本的に変化しない場合は、据え置きモードを選択し、常に画像を投影するようにすることで、携帯電子機器１０を置いた状態で画像を投影させることができる。これにより、操作者は、特に操作することなく画像を投影させ続けることができる。なお、所定位置に置かれている場合は、基本的に、光の照射位置が急激に変化することはないので、プロジェクタ３４から照射される光が人間の顔を照明する可能性は低い。そのため、画像を投影させ続けても、人間にまぶしい思いをさせる可能性を少なくすることができる。 Similarly to the conventional projector, when the image projection position does not change basically, such as when the portable electronic device 10 is placed on a desk, chair, or table, the stationary mode is selected and the image is always projected. By doing so, it is possible to project an image with the portable electronic device 10 placed. Thereby, the operator can continue projecting the image without any particular operation. Note that, when placed at a predetermined position, basically, the light irradiation position does not change abruptly, and therefore, the possibility that the light emitted from the projector 34 illuminates the human face is low. Therefore, even if the image is continuously projected, it is possible to reduce the possibility of dazzling humans.
　このように、使用状態に応じて、動作制御を切り換え可能にすることで、人間に対して光を照射する可能性をより低減しつつ、操作性も高くすることができる。 Thus, by making it possible to switch the operation control according to the use state, it is possible to further improve the operability while further reducing the possibility of irradiating light to humans.
　ここで、上記実施形態では、専用キー１４を筐体１１の側面に設けたが、専用キー１４を設ける位置は特に限定されず、操作キー１３が設けられている面に設けても、筐体１１の底面に設けてもよい。また、上記実施形態では、携帯モードが選択されている場合は、専用キー１４が押されている場合のみ画像を投影するようにしたが、本発明はこれに限定されず、画像を投影するか否かを決定するキーはどのキーとしてもよい。例えば、操作キー１３の中の特定のキーが押されている場合は、画像を投影するようにしてもよいし、操作キー１３の中のいずれか１つのキーが押されていれば、キーの種類にかかわらず画像を投影するようにしてもよい。また、キーの代わりにタッチパネルを用いている場合は、タッチパネルに触れられている間は画像を投影するようにしてもよい。 Here, in the above embodiment, the dedicated key 14 is provided on the side surface of the housing 11, but the position where the dedicated key 14 is provided is not particularly limited, and the housing may be provided on the surface on which the operation key 13 is provided. 11 may be provided on the bottom surface. In the above embodiment, when the portable mode is selected, the image is projected only when the dedicated key 14 is pressed. However, the present invention is not limited to this, and is the image projected? The key for determining whether or not can be any key. For example, when a specific key in the operation key 13 is pressed, an image may be projected, and if any one key in the operation key 13 is pressed, the key An image may be projected regardless of the type. When a touch panel is used instead of a key, an image may be projected while the touch panel is touched.
　また、上記実施形態では、操作者が、携帯モードとするか据え置きモードとするかを選択するようにしたが、本発明はこれに限定されず、携帯電子機器１０が状態を検出して、自動的に選択するようにしてもよい。 In the above embodiment, the operator selects whether to use the portable mode or the stationary mode. However, the present invention is not limited to this, and the portable electronic device 10 automatically detects the state. May be selected automatically.
　例えば、加速度センサ３６により筐体１１に作用する加速度を検出し、検出した加速度に基づいてモードを選択するように（切り換えるように）してもよい。一例としては、制御部２２は、加速度が検出されない場合、実質的に０と判定できる場合は、据え置きモードとし、それ以外の場合は、携帯モードとするようにしてもよい。また、一定以上の加速度が検出された場合は、携帯モードとするようにしてもよい。このように、加速度に基づいて、モードを切り換えることで、操作者が操作することなく、適切な制御モードを選択することができ、安全性を確保しつつ、操作性をさらに高くすることができる。また、自動的に切り替わるようにすることで、操作者が携帯電子機器１０を保持しているにもかかわらず据え置きモードを選択してしまうことを抑制することができる。 For example, an acceleration acting on the housing 11 may be detected by the acceleration sensor 36, and a mode may be selected (switched) based on the detected acceleration. As an example, when no acceleration is detected, the control unit 22 may be set to the stationary mode if it can be determined to be substantially 0, and may be set to the portable mode in other cases. In addition, when a certain acceleration or more is detected, the mobile mode may be set. In this way, by switching the mode based on the acceleration, an appropriate control mode can be selected without the operator's operation, and the operability can be further enhanced while ensuring safety. . In addition, by switching automatically, it is possible to prevent the operator from selecting the stationary mode even though the portable electronic device 10 is held.
　さらに、制御部２２は、筐体１１に作用する加速度から、力の振動数や、力の大きさ（振幅）を検出し、検出した値が手振れと判定することができる数値である場合は、携帯モードを選択するようにすればよい。このように、手振れに基づいて操作者が持っているか判定することで、操作者が持っているときに発生する揺れとそれ以外の揺れ（例えば、机に物がぶつかったときに生じる揺れ）とを識別することができ、より操作性を高くすることができる。 Further, the control unit 22 detects the vibration frequency of the force and the magnitude (amplitude) of the force from the acceleration acting on the housing 11, and when the detected value is a numerical value that can be determined as camera shake, The portable mode may be selected. In this way, by determining whether the operator has it based on hand shake, the vibration that occurs when the operator has it and other vibrations (for example, the vibration that occurs when an object collides with a desk) Can be identified, and operability can be further improved.
　また、加速度センサ３６で検出した加速度に基づいて、携帯モードか据え置きモードかを選択することに限定されず、携帯電子機器１０を充電する際に使用する外部の電源（例えば、ＡＣアダプタ）と接続しているかを検出し、その検出結果に基づいてモードを選択するようにしてもよい。ここで、電源と携帯電子機器１０とが接続しているか否かを検出する検出器としては、携帯電子機器１０の接続端子が電源と接続しているかを検出する検出センサや、外部から携帯電子機器１０に供給される電力、電圧及び／または電流を検出する検出センサを用いることができる。 Further, the present invention is not limited to selecting the portable mode or the stationary mode based on the acceleration detected by the acceleration sensor 36, but connected to an external power source (for example, an AC adapter) used when charging the portable electronic device 10. The mode may be selected based on the detection result. Here, as a detector that detects whether or not the power source and the portable electronic device 10 are connected, a detection sensor that detects whether or not the connection terminal of the portable electronic device 10 is connected to the power source, or a portable electronic device from the outside A detection sensor for detecting power, voltage and / or current supplied to the device 10 can be used.
　このように、携帯電子機器１０が電源に接続されている否かに基づいて、モードを切り換える場合は、電源に接続されていることを検出したら据え置きモードを選択し、電源に接続されていることを検出しなかったら、つまり、電源に接続されていないことを検出したら携帯モードを選択するよう設定することができる。これにより、電源（電源コード）と接続され、移動が制限される場合は据え置きモードとし、移動に制限がない場合は、携帯モードとすることができ、安全性と操作性を高くすることができる。 As described above, when switching the mode based on whether or not the portable electronic device 10 is connected to the power source, when it is detected that the portable electronic device 10 is connected to the power source, the deferred mode is selected and connected to the power source. If it is not detected, that is, it is detected that the mobile phone is not connected to the power source, the mobile mode can be selected. Thereby, when connected to a power source (power cord) and movement is restricted, the stationary mode can be set, and when movement is not restricted, the portable mode can be set, and safety and operability can be enhanced. .
　なお、電力を検出する場合は、供給される電力、電圧及び／または電流に基づいて、備え付けのコンセント等の商用電源から供給されるか、乾電池、ＵＳＢで接続されたＰＣ等のバッテリから供給されるかを識別することが好ましい。なお、このように識別できる場合は、商用電源から電力が供給されている場合に据え置きモードとすることが好ましい。これにより、乾電池等の自在に移動可能な電源に接続されている場合と、コードにより移動範囲が制限される商用電源に接続されている場合とで選択するモードを変えることができ、安全性と操作性をより高くすることができる。 When power is detected, it is supplied from a commercial power source such as an attached outlet based on the supplied power, voltage and / or current, or from a battery such as a dry battery or a PC connected via USB. It is preferable to identify whether or not. In addition, when it can identify in this way, it is preferable to set it as a deferment mode, when electric power is supplied from commercial power supply. As a result, the mode to be selected can be changed between when connected to a freely movable power source such as a dry battery and when connected to a commercial power source whose movement range is limited by a cord. The operability can be further increased.
　また、携帯電子機器１０を充電する際等に、携帯電子機器１０を置く充電台に置かれているかを検出し、その検出結果に基づいてモードを選択するようにしてもよい。ここで、携帯電子機器１０が充電台に置かれているかを検出する検出器としては、筐体１１の充電台との接触位置に接触検出センサを設ければよい。 In addition, when charging the portable electronic device 10 or the like, it may be detected whether the portable electronic device 10 is placed on a charging stand on which the portable electronic device 10 is placed, and the mode may be selected based on the detection result. Here, as a detector for detecting whether the portable electronic device 10 is placed on the charging stand, a contact detection sensor may be provided at a contact position of the housing 11 with the charging stand.
　このように、携帯電子機器１０が充電台に置かれているか否かに基づいて、モードを切り換える場合は、充電台に置かれていることを検出したら据え置きモードを選択し、充電台に置かれていることを検出しなかったら、つまり、充電台に置かれていないことを検出したら携帯モードを選択するよう設定することができる。これにより、充電台に置かれ、移動が制限される場合は据え置きモードとし、移動に制限がない場合は、携帯モードとすることができる。 As described above, when switching the mode based on whether or not the portable electronic device 10 is placed on the charging stand, when it is detected that the portable electronic device 10 is placed on the charging stand, the stationary mode is selected and placed on the charging stand. If it is not detected, that is, if it is detected that the mobile phone is not placed on the charging stand, the mobile mode can be set to be selected. Thereby, when it is placed on the charging stand and the movement is restricted, the stationary mode is set, and when the movement is not restricted, the portable mode can be set.
　また、本発明は、携帯電子機器１０の状態に応じて、つまり、携帯電子機器１０が電源に接続されているか否か、または、充電台に置かれているか否かに応じてモードを決定することにも限定されない。 Further, the present invention determines the mode according to the state of the mobile electronic device 10, that is, whether the mobile electronic device 10 is connected to a power source or placed on a charging stand. It is not limited to that.
　ここで、図５－１から図５－４は、それぞれ、携帯電子機器の制御の一例、つまり、動作パターンを示す説明図である。まず、図５－１に示す動作パターンは、携帯電子機器１０が充電台に置かれている場合及び／または電源に接続されている場合は、据え置きモードを選択可能、携帯モードを選択不可能とし、携帯電子機器１０が充電台に置かれておらずかつ電源に接続されていない場合は、据え置きモードを選択不可能、携帯モードを選択可能とする動作パターンである。つまり、図５－１に示す動作パターンは、上述した携帯電子機器１０の状態に応じて１つのモードを選択する動作パターンである。 Here, FIGS. 5A to 5D are explanatory diagrams showing an example of the control of the portable electronic device, that is, the operation pattern. First, in the operation pattern shown in FIG. 5-1, when the portable electronic device 10 is placed on a charging stand and / or connected to a power source, the stationary mode can be selected and the portable mode cannot be selected. When the portable electronic device 10 is not placed on the charging stand and is not connected to the power source, the operation pattern is such that the stationary mode cannot be selected and the portable mode can be selected. That is, the operation pattern illustrated in FIG. 5A is an operation pattern in which one mode is selected according to the state of the mobile electronic device 10 described above.
　次に、図５－２に示す動作パターンは、携帯電子機器１０が充電台に置かれている場合及び／または電源に接続されている場合は、据え置きモードを選択可能、携帯モードを選択不可能とし、携帯電子機器１０が充電台に置かれておらずかつ電源に接続されていない場合は、据え置きモードと携帯モードの両方を選択可能とする動作パターンである。この動作パターンのときは、携帯電子機器１０が充電台に置かれておらずかつ電源に接続されていない場合に、操作者が、据え置きモードにするか携帯モードにするかを選択することができる。 Next, in the operation pattern shown in FIG. 5B, when the portable electronic device 10 is placed on the charging stand and / or connected to the power source, the stationary mode can be selected, and the portable mode cannot be selected. When the portable electronic device 10 is not placed on the charging stand and is not connected to the power source, the operation pattern is such that both the stationary mode and the portable mode can be selected. In this operation pattern, when the portable electronic device 10 is not placed on the charging stand and is not connected to the power source, the operator can select the stationary mode or the portable mode. .
　次に、図５－３に示す動作パターンは、携帯電子機器１０が充電台に置かれている場合及び／または電源に接続されている場合は、据え置きモードと携帯モードの両方を選択可能とし、携帯電子機器１０が充電台に置かれておらずかつ電源に接続されていない場合は、据え置きモードを選択不可能、携帯モードを選択可能とする動作パターンである。この動作パターンのときは、携帯電子機器１０が充電台に置かれている場合及び／または電源に接続されている場合に、操作者が、据え置きモードにするか携帯モードにするかを選択することができる。 Next, the operation pattern shown in FIG. 5-3 allows both the stationary mode and the portable mode to be selected when the portable electronic device 10 is placed on the charging stand and / or connected to the power source. When the portable electronic device 10 is not placed on the charging stand and is not connected to a power source, the operation pattern is such that the stationary mode cannot be selected and the portable mode can be selected. In this operation pattern, when the portable electronic device 10 is placed on the charging stand and / or connected to the power source, the operator selects whether to set the stationary mode or the portable mode. Can do.
　また、図５－４に示す動作パターンは、携帯電子機器１０が充電台に置かれている場合及び／または電源に接続されている場合も、携帯電子機器１０が充電台に置かれておらずかつ電源に接続されていない場合も、据え置きモードと携帯モードの両方を選択可能とする動作パターンである。この動作パターンのときは、いずれの場合も操作者が、据え置きモードにするか携帯モードにするかを選択することができる。 Further, the operation pattern shown in FIG. 5-4 shows that the portable electronic device 10 is not placed on the charging stand even when the portable electronic device 10 is placed on the charging stand and / or connected to the power source. In addition, even when not connected to a power source, the operation pattern enables selection of both the stationary mode and the portable mode. In this case, the operator can select either the stationary mode or the portable mode in any case.
　このように、図５－１から図５－４に示す４つのいずれの動作パターンとしても、２つのモードを選択することができ、安全性と操作性を高くすることができる。また、操作者が、４つの動作パターンから１つの動作パターンを設定できるようにしてもよいし、４つの動作パターンの中の１つの動作パターンのみをアプリケーションプログラムとして記憶させるようにしてもよい。 Thus, in any of the four operation patterns shown in FIGS. 5-1 to 5-4, two modes can be selected, and safety and operability can be improved. Further, the operator may be able to set one operation pattern from the four operation patterns, or only one operation pattern among the four operation patterns may be stored as an application program.
　また、上記実施形態では、携帯電子機器１０に加速度センサ３６を設けたが、携帯モードと据え置きモードとを選択する際に加速度の検出結果を用いない場合は、必ずしも設ける必要はない。例えば、モードの選択を操作者の選択操作のみにより行う場合は、加速度センサを設ける必要はない。 In the above embodiment, the acceleration sensor 36 is provided in the portable electronic device 10. However, when the acceleration detection result is not used when selecting the portable mode and the stationary mode, the acceleration sensor 36 is not necessarily provided. For example, when the mode is selected only by the operator's selection operation, it is not necessary to provide an acceleration sensor.
　また、上記実施形態では、据え置きモードの場合は、画像を投影し続けるとしたがこれに限定されず、プロジェクタ３４が光を照射する方向に人間がいることを検出したら、画像の投影を停止してもよい。このように、光の照射方向に人間がいる場合は、画像の投影を停止させることで、人間にまぶしい思いをさせる可能性を低減することができ、安全性をより高くすることができる。ここで、プロジェクタ３４が光を照射する方向に人間がいるか否かを検出する方法は特に限定されない。例えば、近接センサを設け、光の照射方向に、携帯電子機器１０（筐体１１）から一定距離以内に物体があることを検出したら、人間がいると判定するようにしもよい。また、光センサや、赤外線センサ等により検出するようにしてもよい。 In the above-described embodiment, the image is continuously projected in the stationary mode. However, the present invention is not limited to this. When the projector 34 detects that a person is in the light irradiation direction, the projection of the image is stopped. May be. As described above, when a person is present in the light irradiation direction, by stopping the projection of the image, it is possible to reduce the possibility that the person will be dazzled and to further increase safety. Here, the method for detecting whether or not there is a person in the direction in which the projector 34 emits light is not particularly limited. For example, a proximity sensor may be provided, and it may be determined that there is a person when it is detected that there is an object within a certain distance from the portable electronic device 10 (housing 11) in the light irradiation direction. Moreover, you may make it detect with an optical sensor, an infrared sensor, etc.
　また、筐体にスイッチを設け、据置きモードの場合もそのスイッチが押されている場合のみプロジェクタから光を投影させるようにしてもよい。以下、具体例とともに説明する。ここで、図６－１は、携帯電子機器の他の実施形態の概略構成を示す斜視図であり、図６－２は、図６－１に示す携帯電子機器の概略構成を他の角度から示す斜視図である。図６－１及び図６－２に示す携帯電子機器１００は、筐体１１０のディスプレイ１２及び操作キー１３が設けられている面とは反対側の面（以下「背面）という。）にスイッチ部材１１２が設けられている。なお、携帯電子機器１００は、スイッチ部材１１２を設けたことを除いて他の構成は、図１及び図２に示す携帯電子機器１０と同様である。 Also, a switch may be provided on the housing, and light may be projected from the projector only in the stationary mode when the switch is pressed. Hereinafter, it will be described together with specific examples. Here, FIG. 6-1 is a perspective view showing a schematic configuration of another embodiment of the portable electronic device, and FIG. 6-2 shows a schematic configuration of the portable electronic device shown in FIG. 6-1 from another angle. It is a perspective view shown. The portable electronic device 100 shown in FIGS. 6A and 6B has a switch member on the surface of the housing 110 opposite to the surface on which the display 12 and the operation keys 13 are provided (hereinafter referred to as “rear surface”). The portable electronic device 100 is the same as the portable electronic device 10 shown in FIGS. 1 and 2 except that the switch member 112 is provided.
　スイッチ部材１１２は、筐体１１０の背面に背面よりも突出して配置され、他の部材と接触しているかを検出する。ここで、他の部材としては、携帯電子機器１００を載置する種々の部材、例えば、床、机、台等がある。スイッチ部材１１２は、他の部材と接触することで外力が負荷されると筐体１１０の内部側に移動され、ＯＮの状態となる。また、スイッチ部材１１２は、ばね等の付勢部材が設けられており、他の部材と接触していない状態では、自然状態の位置、つまり、背面よりも一定距離突出した状態に戻り、ＯＦＦの状態となる。スイッチ部材１１２は、このＯＮ／ＯＦＦの状態を示す信号を制御部２２（図２参照）に送る。 The switch member 112 is disposed on the back surface of the housing 110 so as to protrude from the back surface, and detects whether it is in contact with other members. Here, as other members, there are various members on which the portable electronic device 100 is placed, for example, a floor, a desk, a stand, and the like. When an external force is applied by contacting the switch member 112 with another member, the switch member 112 is moved to the inside of the housing 110 and is turned on. In addition, the switch member 112 is provided with a biasing member such as a spring, and returns to a natural state, that is, a state in which the switch member 112 protrudes a certain distance from the back surface when not in contact with other members. It becomes a state. The switch member 112 sends a signal indicating the ON / OFF state to the control unit 22 (see FIG. 2).
　携帯電子機器１００の制御部２２は、据置きモードが選択されていると判定したら、スイッチ部材１１２のＯＮ／ＯＦＦの信号を検出し、スイッチ部材１１２からＯＮの信号が発信されていることを検出したら、プロジェクタ３４から画像を投影させ、スイッチ部材１１２からＯＦＦの信号が発信されていることを検出したら、プロジェクタ３４から画像を投影させない、つまり、ＯＦＦの信号が発信されている間は、画像の投影を停止する。 When determining that the stationary mode is selected, the control unit 22 of the portable electronic device 100 detects the ON / OFF signal of the switch member 112 and detects that the ON signal is transmitted from the switch member 112. When the projector 34 projects an image and detects that an OFF signal is transmitted from the switch member 112, the projector 34 does not project an image, that is, while the OFF signal is transmitted, Stop projection.
　このように、携帯電子機器１００は、据置きモードが選択されている時は、スイッチ部材１１２が他の部材と接触している場合のみ画像を投影するようにすることで、携帯電子機器１００（の筐体１１０）が他の部材に載置されている場合のみプロジェクタ３４から光を射出させるようにすることができる。このように、携帯電子機器１００が載置されている物体から離れたことを検出することで、据置きモードの場合に、持ち上げられたり、机から落下したりした場合に、光の射出を停止することができる。これにより、光が射出される方向が急に変化し、人間にまぶしい思いをさせる可能性をより少なくすることができる。また、据置きモードが選択されている場合は、所定の向きで他の部材に載置されている場合のみ画像を投影させるようにすることができ、画像を正しい向きで投影することができる。つまり、筐体１１０の背面以外の面を他の部材に接触した状態で載置しても画像が投影されないため、画像が横向きで投影されたりすることを抑制することができる。 Thus, when the stationary mode is selected, the portable electronic device 100 projects an image only when the switch member 112 is in contact with another member, so that the portable electronic device 100 ( The light can be emitted from the projector 34 only when the housing 110) is placed on another member. In this way, by detecting that the portable electronic device 100 has moved away from the object on which it is placed, the light emission is stopped when the portable electronic device 100 is lifted or dropped from the desk in the stationary mode. can do. As a result, the direction in which the light is emitted changes suddenly, and it is possible to reduce the possibility of making people feel dazzling. Further, when the stationary mode is selected, the image can be projected only when it is placed on another member in a predetermined orientation, and the image can be projected in the correct orientation. That is, even if the surface other than the back surface of the housing 110 is placed in contact with another member, the image is not projected, so that it is possible to prevent the image from being projected sideways.
　なお、携帯電子機器１００では、スイッチ部材からＯＮ、ＯＦＦの両方の信号を発信するようにしたが、ＯＮ、ＯＦＦの信号の一方のみを発信させるようにしてもよい。例えば、ＯＮの状態のときのみ信号を発信させるようにし、制御部２２は、据置きモードの場合にスイッチ部材から信号が発信されていることを検出した場合のみプロジェクタ３４から画像を投影させるようにしてもよい。 In the portable electronic device 100, both the ON and OFF signals are transmitted from the switch member, but only one of the ON and OFF signals may be transmitted. For example, a signal is transmitted only when it is in an ON state, and the control unit 22 projects an image from the projector 34 only when it is detected that a signal is transmitted from the switch member in the stationary mode. May be.
　上記実施形態では、スイッチ部材を外力の作用により移動し、その移動を検出することでＯＮ／ＯＦＦの切り替えを機械的に検出するスイッチを用いたが、他の部材との接触を検出する接触検出部であればよく、他の部材との接触を電気的に検出するスイッチも用いることができる。例えば、筐体１１０の背面に接触端子を設け、接触端子が他の部材と接触したら、電流等が流れ、信号が発信されるスイッチとしてもよい。 In the above-described embodiment, the switch member is moved by the action of an external force, and the switch that mechanically detects ON / OFF switching by detecting the movement is used. However, contact detection that detects contact with other members is used. A switch that electrically detects contact with other members can also be used. For example, a contact terminal may be provided on the back surface of the housing 110, and when the contact terminal comes into contact with another member, a current or the like may flow and a switch may be transmitted.
　また、スイッチ部材を携帯モードと判定されているときに光を投影するために押下する専用キーとしても用いるようにしてもよい。ここで、スイッチ部材を専用キーとして用い、携帯モードで画像を投影する場合は、加速度センサにより鉛直方向の上下方向を検出して、携帯電子機器１００の筐体１１０の向き、つまり背面が鉛直方向上向きとなっているか下向きになっているかを判定し、画像の上側が、鉛直方向上側となるように、投影する画像の向きを制御するようにすることが好ましい。このように、加速度センサの検出した鉛直方向の情報に基づいて、投影する画像の向きを設定することで、操作者が携帯電子機器の筐体を操作しやすい任意の向きで持った状態でも正しい方向に画像を投影することができる。例えば、スイッチ部材を押しやすいように、筐体の背面を鉛直方向上側に向けて保持しても、制御部の制御により、据置きモードとは反対向きにした画像を投影するため照射面には、正しい向きで画像を投影させることができる。これにより、画像を見やすくすることができ、かつ、操作性を高くすることができる。 Also, the switch member may be used as a dedicated key that is pressed to project light when it is determined to be in the portable mode. Here, when the switch member is used as a dedicated key and an image is projected in the portable mode, the vertical direction of the vertical direction is detected by the acceleration sensor, and the orientation of the casing 110 of the portable electronic device 100, that is, the back surface is the vertical direction. It is preferable to determine whether it is upward or downward and to control the orientation of the image to be projected so that the upper side of the image is the upper side in the vertical direction. In this way, by setting the orientation of the image to be projected based on the vertical direction information detected by the acceleration sensor, it is correct even when the operator holds the casing of the portable electronic device in any orientation that is easy to operate. An image can be projected in the direction. For example, even if the back surface of the housing is held vertically upward so that the switch member can be easily pushed, the irradiation surface is projected to project an image opposite to the stationary mode by the control of the control unit. The image can be projected in the correct orientation. Thereby, it is possible to make the image easy to see and to improve operability.
　なお、上記では、筐体の向きを検出するセンサとして加速度センサを用いたが、筐体の向きを検出するセンサは、加速度センサに限定されない。例えば、地磁気センサも用いることができる。なお、センサとしては、部品点数を少なくすることができるため、他の機能にも用いるセンサを使用することが好ましい。従って、据置きモードと携帯モードとを判定するために加速度センサを用いる場合は、筐体の向きを検出するセンサとして、加速度センサを用いることが好ましい。 In the above description, the acceleration sensor is used as the sensor for detecting the orientation of the housing. However, the sensor for detecting the orientation of the housing is not limited to the acceleration sensor. For example, a geomagnetic sensor can also be used. As the sensor, since the number of parts can be reduced, it is preferable to use a sensor used for other functions. Therefore, when using an acceleration sensor to determine the stationary mode and the portable mode, it is preferable to use an acceleration sensor as a sensor for detecting the orientation of the housing.
　また、携帯電子機器１００では、背面の一部にスイッチ部材を設けたが、スイッチ部材の配置位置は、これに限定されない。図７－１は、携帯電子機器の他の実施形態の概略構成を示す斜視図であり、図７－２は、図７－１に示す携帯電子機器の概略構成を他の角度から示す斜視図である。図７－１及び図７－２に示す携帯電子機器１２０は、筐体１２２の背面に、スタンド１２４が設けられ、スタンド１２４の他の部材と接触する面にスイッチ部材１２６が設けられている。なお、携帯電子機器１２０も、スタンド１２４とスイッチ部材１２６とを設けたことを除いて他の構成は、図１及び図２に示す携帯電子機器１０と同様である。 In the portable electronic device 100, the switch member is provided on a part of the back surface, but the position of the switch member is not limited to this. FIG. 7A is a perspective view illustrating a schematic configuration of another embodiment of the portable electronic device, and FIG. 7B is a perspective view illustrating the schematic configuration of the portable electronic device illustrated in FIG. It is. In the portable electronic device 120 shown in FIGS. 7-1 and 7-2, a stand 124 is provided on the back surface of the housing 122, and a switch member 126 is provided on a surface that contacts other members of the stand 124. The portable electronic device 120 is the same as the portable electronic device 10 shown in FIGS. 1 and 2 except that the stand 124 and the switch member 126 are provided.
　スタンド１２４は、筐体１２２の背面のプロジェクタ３４側の領域に設けられた凹部に収納可能な棒状部材であり、一方の端部が筐体１２２に回動可能な状態で支持されている。スタンド１２４は、棒状部材の中心軸が、背面と平行になる角度から背面と直交する角度まで、つまり９０度の範囲で回動する。 The stand 124 is a rod-like member that can be housed in a recess provided in a region on the projector 34 side on the back of the housing 122, and one end thereof is supported by the housing 122 in a rotatable state. The stand 124 rotates in a range of 90 degrees from the angle at which the central axis of the rod-shaped member is parallel to the back surface to the angle orthogonal to the back surface.
　また、スタンド１２４は、棒状部材の中心軸が背面と平行となっている状態では、筐体１２２の凹部に収納され、スタンド１２４の一面が、背面と同一平面にある状態となる。スタンド１２４が筐体１２２の凹部に収納されている状態で、筐体１２２の背面側を他の部材と接触させると、筐体１２２の背面の全面及び、スタンド１２４の一面が他の部材と接触する。 Further, the stand 124 is housed in the recess of the housing 122 in a state where the central axis of the rod-shaped member is parallel to the back surface, and one surface of the stand 124 is in the same plane as the back surface. When the back surface of the housing 122 is brought into contact with another member in a state where the stand 124 is housed in the recess of the housing 122, the entire back surface of the housing 122 and one surface of the stand 124 are in contact with the other members. To do.
　また、スタンド１２４は、棒状部材の中心軸が背面と直交している状態では、スタンド１２４の回転軸となっている端部とは反対側の端部が、筐体１２２の背面よりも突出した状態となる。スタンド１２４の一部が筐体１２２の凹部から突出している状態で、筐体１２２の背面側を他の部材と接触させると、スタンド１２４と、筐体１２２の背面のプロジェクタ３４側とは反対側の端面とが、他の部材と接触し、他の部材を支持する。背面よりも突出したスタンド１２４と筐体１２２を支持することで、筐体１２２の背面が他の部材に対して所定角度傾斜した状態で支持される。 In addition, in the state where the central axis of the bar-shaped member is orthogonal to the back surface of the stand 124, the end opposite to the end serving as the rotation shaft of the stand 124 protrudes from the back surface of the housing 122. It becomes a state. When the back surface side of the housing 122 is brought into contact with another member in a state where a part of the stand 124 protrudes from the concave portion of the housing 122, the stand 124 is opposite to the projector 34 side on the back surface of the housing 122. The end surface of this is in contact with the other member and supports the other member. By supporting the stand 124 and the housing 122 protruding from the back surface, the back surface of the housing 122 is supported in a state where it is inclined at a predetermined angle with respect to other members.
　スイッチ部材１２６は、スタンド１２４の筐体１２２に支持されていない側の端部の端面に配置され、他の部材と接触しているかを検出する。なお、スイッチ部材１２６は、配置位置を除いて他の構成は、上述した携帯電子機器１００のスイッチ部材１１２と同様であるので、その詳細な説明は省略する。スイッチ部材１２６は、他の部材と接触することで外力が負荷されるとスタンド１２４の内部側に移動され、ＯＮの状態となる。また、携帯電子機器１２０も、スイッチ部材１２６により他の部材と接触しているかを検出し、据置きモードが選択されている時は、スイッチ部材１２６が他の部材と接触している場合のみ画像を投影するようにし、携帯電子機器１００（の筐体１１０）が他の部材に載置されている場合のみプロジェクタ３４から光を射出させるようにする。 The switch member 126 is disposed on the end surface of the end portion of the stand 124 that is not supported by the casing 122, and detects whether it is in contact with another member. The switch member 126 is the same in configuration as the switch member 112 of the above-described portable electronic device 100 except for the arrangement position, and a detailed description thereof will be omitted. When an external force is applied by contacting the switch member 126 with another member, the switch member 126 is moved to the inside of the stand 124 and is turned on. In addition, the portable electronic device 120 also detects whether the switch member 126 is in contact with another member. When the stationary mode is selected, the image is only displayed when the switch member 126 is in contact with the other member. The projector 34 emits light only when the portable electronic device 100 (the casing 110 thereof) is placed on another member.
　これにより、携帯電子機器１２０のように、スタンド１２４を設けた場合でも、スタンド１２４が他の部材と接触している場合のみ光を射出させるようにすることができ、光が射出される方向が急に変化し、人間の目に光が入ることを抑制でき、人間にまぶしい思いをさせる可能性をより少なくすることができる。また、据置きモードが選択されている場合は、所定の向きで他の部材に載置されている場合のみ画像を投影させるようにすることができ、画像を正しい向きで投影することができる。 Accordingly, even when the stand 124 is provided as in the portable electronic device 120, it is possible to emit light only when the stand 124 is in contact with other members, and the direction in which the light is emitted is changed. It can change suddenly, suppress the light from entering the human eye, and reduce the possibility of dazzling humans. Further, when the stationary mode is selected, the image can be projected only when it is placed on another member in a predetermined orientation, and the image can be projected in the correct orientation.
　また、携帯電子機器１２０は、スタンド１２４を設けることで、プロジェクタ３４から射出させる光が他の部材（机等）に投影されてしまうことを抑制することができる。つまり、水平方向よりも鉛直方向上側に所定角度上向いた向きに画像を照射できるため、投影された画像のうち背面側の部分が他の部材に投影されることを抑制することができる。さらに、スタンド１２４を設け、かつ、スタンド１２４にスイッチ部材１２６を設けることで、スタンド１２４を使用して、他の部材に載置した場合のみ光を射出させるようにすることができる。これにより、携帯電子機器１２０は、所定の向きで、所定の姿勢の場合のみ光を射出させるようにすることができる。 Moreover, the portable electronic device 120 can suppress the light emitted from the projector 34 from being projected onto another member (desk or the like) by providing the stand 124. In other words, since the image can be irradiated in a direction upward by a predetermined angle above the horizontal direction, it is possible to suppress the rear side portion of the projected image from being projected onto another member. Furthermore, by providing the stand 124 and providing the switch member 126 on the stand 124, it is possible to emit light only when the stand 124 is used and placed on another member. Thereby, the portable electronic device 120 can emit light only in a predetermined orientation and in a predetermined posture.
　また、上記実施形態では、スイッチ部材１２６をスタンド１２４の他の部材と接触する面に設けたが、本発明はこれに限定されず、携帯電子機器の筐体が他の部材と接触していることが検出できれば、その配置位置は特に限定されない。図８は、携帯電子機器の他の実施形態の概略構成を示す斜視図である。ここで、図８に示す携帯電子機器１３０は、筐体１２２とスタンド１３２との間にスイッチ部材１３４を設けられている。ここで、スタンド１３２は、他の部材と接触している面から筐体１２２の凹部に向けた方向に力が負荷されると、筐体１２２の凹部側に移動する構造となっている。また、スタンド１３２が筐体１２２の凹部側に移動すると、スイッチ部材１３４は、筐体１２２とスタンド１３２とにより挟まれて、押された状態となる。スイッチ部材１３４は、筐体１２２とスタンド１３２とにより押された状態であるか否かを検出し、筐体１２２とスタンド１３２とにより押された状態であると検出したら、ＯＮ状態の信号を出力する。 Moreover, in the said embodiment, although the switch member 126 was provided in the surface which contacts the other member of the stand 124, this invention is not limited to this, The housing | casing of a portable electronic device is contacting the other member. If it can be detected, the arrangement position is not particularly limited. FIG. 8 is a perspective view showing a schematic configuration of another embodiment of the portable electronic device. Here, in the portable electronic device 130 illustrated in FIG. 8, a switch member 134 is provided between the housing 122 and the stand 132. Here, the stand 132 has a structure that moves to the recess side of the housing 122 when a force is applied in a direction from the surface in contact with another member toward the recess of the housing 122. When the stand 132 moves to the concave portion side of the housing 122, the switch member 134 is sandwiched between the housing 122 and the stand 132 and is in a pressed state. The switch member 134 detects whether or not the switch 122 is pressed by the casing 122 and the stand 132. If the switch member 134 detects that the switch member 134 is pressed by the casing 122 and the stand 132, the switch member 134 outputs an ON state signal. To do.
　このように、スイッチ部材１３４は、直接他の部材と接触する位置に配置されていなくとも、筐体１２２やスタンド１３２を介して、携帯電子機器１３０が所定の姿勢で他の部材に載置されていることを検出することができれば、携帯電子機器１００、携帯電子機器１２０と同様の制御を行うことができ、携帯電子機器１００、携帯電子機器１２０と同様の効果を得ることができる。 Thus, even if the switch member 134 is not disposed at a position in direct contact with another member, the portable electronic device 130 is placed on the other member in a predetermined posture via the housing 122 or the stand 132. If it can be detected, the same control as the portable electronic device 100 and the portable electronic device 120 can be performed, and the same effect as the portable electronic device 100 and the portable electronic device 120 can be obtained.
　また、上記ではいずれも携帯電子機器の筐体がストレート形状の場合を例として説明したが、他の形状の場合も同様である。以下、具体例とともに説明する。まず、図９は、携帯電子機器の他の実施形態の概略構成を示す斜視図である。図９に示す携帯電子機器１６０は、いわゆる折りたたみ形状の携帯電子機器であり、筐体１６２が、第１筐体１６２ａと第２筐体１６２ｂとで形成されている。この第１筐体１６２ａと第２筐体１６２ｂとは、ヒンジ１６３を介して開閉可能な状態で連結されている。具体的には、第１筐体１６２ａ及び第２筐体１６２ｂは、ヒンジ１６３を中心としてともに回動して、互いに遠ざかる方向及び互いに接近する方向に回動できるように構成される。第１筐体１６２ａと第２筐体１６２ｂとが互いに遠ざかる方向に回動すると携帯電子機器１６０が開き、第１筐体１６２ａと第２筐体１６２ｂとが互いに接近する方向に回動すると携帯電子機器１６０が閉じる。また、第１筐体１６２ａのヒンジ１６３が設けられている端部とは反対側の端部には、プロジェクタ３４が設けられている。 Also, in the above description, the case where the casing of the portable electronic device has a straight shape has been described as an example, but the same applies to other shapes. Hereinafter, it will be described together with specific examples. First, FIG. 9 is a perspective view showing a schematic configuration of another embodiment of the portable electronic device. A portable electronic device 160 illustrated in FIG. 9 is a so-called foldable portable electronic device, and a housing 162 includes a first housing 162a and a second housing 162b. The first casing 162a and the second casing 162b are connected via a hinge 163 in an openable / closable state. Specifically, the first housing 162a and the second housing 162b are configured to rotate together around the hinge 163 and to rotate in a direction away from each other and a direction approaching each other. When the first casing 162a and the second casing 162b rotate in a direction away from each other, the portable electronic device 160 opens, and when the first casing 162a and the second casing 162b rotate in a direction approaching each other, the portable electronic device 160 opens. The device 160 is closed. In addition, a projector 34 is provided at the end of the first housing 162a opposite to the end where the hinge 163 is provided.
　また、スイッチ部材１６４は、第２筐体１６２ｂの閉じられた状態のときに第１筐体１６２ａと向かい合う面とは反対側の面、つまり、背面に相当する面に設けられている。なお、スイッチ部材１６４の構成は、スイッチ部材１１２と同様であるので、その詳細な説明は省略する。 Further, the switch member 164 is provided on the surface opposite to the surface facing the first housing 162a when the second housing 162b is closed, that is, the surface corresponding to the back surface. The configuration of the switch member 164 is the same as that of the switch member 112, and thus detailed description thereof is omitted.
　携帯電子機器１６０のように、折りたたみ形状としても、携帯電子機器１６０が他の部材と接触しているかを検出するスイッチ部材を設け、携帯電子機器１００、１２０と同様の操作をすることで、携帯電子機器１００、１２０と同様の効果を得ることができる。 Like the portable electronic device 160, even when the portable electronic device 160 is folded, a switch member that detects whether the portable electronic device 160 is in contact with other members is provided, and the portable electronic device 100 and 120 can be The same effects as those of the electronic devices 100 and 120 can be obtained.
　図１０は、携帯電子機器の他の実施形態の概略構成を示す斜視図である。また、図１１－１は、図１０に示す携帯電子機器の動作を説明するための説明図であり、図１１－２は、図１０に示す携帯電子機器の動作を説明するための説明図である。図１０に示す携帯電子機器１８０は、いわゆる２軸ヒンジの折りたたみ形状の携帯電子機器であり、筐体１８２が、第１筐体１８２ａと第２筐体１８２ｂとで構成されている。この第１筐体１８２ａと第２筐体１８２ｂとは、ヒンジ１８３を介して連結されている。また、ヒンジ１８３は、第１筐体１８２ａと第２筐体１８２ｂとを、開閉方向及びねじれ方向の２つの回転軸で相対的に回転させる。ここで、ねじれ方向とは、開閉方向の回転軸に直交し、かつ、第１筐体１８２ａのヒンジ１８３と接続されている端部から先端に向けて伸びる線を軸として回転する方向である。具体的には、まず、第１筐体１８２ａ及び第２筐体１８２ｂは、ヒンジ１８３を中心としてともに回動して、互いに遠ざかる方向及び互いに接近する方向に回動できるように構成される。第１筐体１８２ａと第２筐体１８２ｂとが互いに遠ざかる方向に回動すると携帯電子機器１８０が開き、第１筐体１８２ａと第２筐体１８２ｂとが互いに接近する方向に回動すると携帯電子機器１８０が閉じる。さらに、第１筐体１８２ａ及び第２筐体１８２ｂは、ヒンジ１８３の中央を通り、且つ回転方向の回転軸に直交する線を回転軸として、第１筐体１８２ａのディスプレイ１２が形成されている面と、第２筐体１８２ｂの操作キー１３が設けられている面とがねじれる方向に回転する。 FIG. 10 is a perspective view showing a schematic configuration of another embodiment of the portable electronic device. 11A is an explanatory diagram for explaining the operation of the portable electronic device shown in FIG. 10, and FIG. 11B is an explanatory diagram for explaining the operation of the portable electronic device shown in FIG. is there. A portable electronic device 180 illustrated in FIG. 10 is a so-called biaxial hinge-folded portable electronic device, and the housing 182 includes a first housing 182a and a second housing 182b. The first casing 182a and the second casing 182b are connected via a hinge 183. Further, the hinge 183 relatively rotates the first housing 182a and the second housing 182b with two rotation axes in the opening / closing direction and the twisting direction. Here, the torsional direction is a direction that rotates around an axis that is orthogonal to the rotation axis in the opening / closing direction and that extends from the end connected to the hinge 183 of the first housing 182a toward the tip. Specifically, first, the first housing 182a and the second housing 182b are configured to rotate together around the hinge 183 and to rotate in a direction away from each other and a direction approaching each other. When the first housing 182a and the second housing 182b rotate in a direction away from each other, the portable electronic device 180 opens, and when the first housing 182a and the second housing 182b rotate in a direction approaching each other, the mobile electronic device The device 180 is closed. Further, the first housing 182a and the second housing 182b are formed with the display 12 of the first housing 182a with a line passing through the center of the hinge 183 and orthogonal to the rotation axis in the rotation direction as the rotation axis. The surface and the surface on which the operation key 13 of the second housing 182b is provided rotate in a twisting direction.
　また、第１筐体１８２ａのヒンジ１８３が設けられている端部とは反対側の端部には、プロジェクタ３４が設けられている。さらに、第１筐体１８２ａの側面、つまり、ねじれ方向の回転時に外周面となる面のヒンジ１８３側の端部には、スイッチ１８４が設けられている。なお、スイッチ部材１８４の構成は、スイッチ部材１１２と同様であるので、その詳細な説明は省略する。 Further, a projector 34 is provided at the end of the first housing 182a opposite to the end where the hinge 183 is provided. Further, a switch 184 is provided on the side surface of the first housing 182a, that is, on the end portion on the hinge 183 side of the surface that becomes the outer peripheral surface when rotating in the twisting direction. The configuration of the switch member 184 is the same as that of the switch member 112, and thus detailed description thereof is omitted.
　携帯電子機器１８０は、図１０、図１１－１及び図１１－２に示すように、携帯電子機器１８０の第１筐体１８２ａと第２筐体１８２ｂとをヒンジ１８３を中心として開閉方向に回転させて開き、かつ、第１筐体１８２ａと第２筐体１８２ｂとをヒンジ１８３を中心として、ねじれ方向に相対的に回転させ、スイッチ１８４が形成されている面が第２筐体１８２ｂの背面と略平行となった状態、つまり、図１０に示す状態のときに、据置きモードで画像の投影を行う。 As shown in FIGS. 10, 11-1, and 11-2, the portable electronic device 180 rotates the first housing 182 a and the second housing 182 b of the portable electronic device 180 around the hinge 183 in the opening / closing direction. The first housing 182a and the second housing 182b are rotated relative to each other in the torsional direction around the hinge 183, and the surface on which the switch 184 is formed is the back surface of the second housing 182b. Is projected in the stationary mode in a state substantially parallel to the screen, that is, in the state shown in FIG.
　したがって、携帯電子機器１８０は、図１１－１に示すように、第１筐体１８２ａのスイッチ部材１８４が設けられている部分が他の部材と接触している状態、基本的には、第１筐体１８２ａのスイッチ部材１８４が設けられている部分と第２筐体１８２ｂの一部とが他の部材１９０に接触している状態となったら、スイッチ部材１８４がＯＮの状態となり、プロジェクタ３４から光が射出され、画像を投影する。また、図１１－２に示すように、携帯電子機器１８０が浮いた状態となり、スイッチ部材１８４が他の部材１９０と接触していない状態となったら、スイッチ部材１８４がＯＦＦの状態となり、プロジェクタ３４から光の射出が停止される。 Therefore, as shown in FIG. 11A, the portable electronic device 180 is in a state where the portion where the switch member 184 of the first housing 182a is provided is in contact with other members, basically the first When the portion of the housing 182a where the switch member 184 is provided and a part of the second housing 182b are in contact with the other member 190, the switch member 184 is turned on, and the projector 34 Light is emitted and the image is projected. Also, as shown in FIG. 11B, when the portable electronic device 180 is in a floating state and the switch member 184 is not in contact with the other member 190, the switch member 184 is in an OFF state, and the projector 34 The light emission is stopped.
　携帯電子機器１８０のように、２軸ヒンジの折りたたみ形状としても、携帯電子機器１８０が他の部材と接触しているかを検出するスイッチ部材を設け、携帯電子機器１００、１２０、１６０と同様の操作をすることで、携帯電子機器１００、１２０、１６０と同様の効果を得ることができる。また、第１筐体側のスイッチを設けることで、ねじれ方向に一定回転させて、他の部材に載置した場合のみ画像が投影されるようにすることができ、第１筐体のねじれ方向の位置を所定の位置とすることができる。これにより、第１筐体１８２ａのねじれ方向の角度を検出しなくとも、プロジェクタ３４から投影される画像を適切な向きで投影することができる。なお、上述した種々の実施形態に記載の技術事項を互いに組み合わせてもよい。 Like the portable electronic device 180, even when the biaxial hinge is folded, a switch member that detects whether the portable electronic device 180 is in contact with another member is provided, and the same operation as the portable electronic device 100, 120, 160 is performed. By doing this, it is possible to obtain the same effect as the portable electronic devices 100, 120, and 160. Further, by providing a switch on the first housing side, it is possible to project the image only when it is fixedly rotated in the twisting direction and placed on another member. The position can be a predetermined position. Accordingly, an image projected from the projector 34 can be projected in an appropriate direction without detecting the angle of the first casing 182a in the twist direction. The technical matters described in the various embodiments described above may be combined with each other.
　次に、携帯電子機器を有する携帯ユニットについて説明する。まず、図１２を用いて携帯電子機器を有する携帯ユニットの外観の構成を説明する。ここで、図１２は、携帯電子機器を有する携帯ユニットの一実施形態の概略構成を示す斜視図である。携帯ユニット１は、携帯電子機器１０ａと、携帯電子機器１０ａを支持可能な台である充電台６２と、一方の端部が充電台６２と接続し、他方の端部がＡＣアダプタ、コンセント等の外部電力供給部と接続されている外部電力端子６４とを有する。携帯ユニット１は、携帯電子機器１０ａを充電台６２の所定位置に載置し、充電台６２で携帯電子機器１０ａを支持している状態にしたら、外部電力端子６４と充電台６２を介して外部電力から携帯電子機器１０ａに電力を供給させ、携帯電子機器１０ａを充電、または、携帯電子機器１０ａに電力を供給する。なお、携帯電子機器１０ａは、上述した図１の携帯電子機器１０と略同様の構成である。そこで、携帯電子機器１０ａのうち、携帯電子機器１０と同様の構成の部分には、同一の符号を付してその詳細な説明は省略する。 Next, a portable unit having a portable electronic device will be described. First, an external configuration of a portable unit having a portable electronic device will be described with reference to FIG. Here, FIG. 12 is a perspective view showing a schematic configuration of an embodiment of a portable unit having a portable electronic device. The portable unit 1 includes a portable electronic device 10a, a charging table 62 that is a table that can support the portable electronic device 10a, one end connected to the charging table 62, and the other end connected to an AC adapter, an outlet, etc. And an external power terminal 64 connected to the external power supply unit. When the portable unit 1 places the portable electronic device 10 a at a predetermined position on the charging stand 62 and supports the portable electronic device 10 a with the charging stand 62, the portable unit 1 is externally connected via the external power terminal 64 and the charging stand 62. Electric power is supplied from the electric power to the portable electronic device 10a, and the portable electronic device 10a is charged or supplied to the portable electronic device 10a. Note that the mobile electronic device 10a has substantially the same configuration as the above-described mobile electronic device 10 of FIG. Therefore, in the portable electronic device 10a, the same components as those of the portable electronic device 10 are denoted by the same reference numerals, and detailed description thereof is omitted.
　携帯電子機器１０ａは、無線通信機能を備えた携帯電話機である。携帯電子機器１０ａは、１つの箱型形状の筐体１１の内部に各部が収納されたストレート形状の携帯電話機である。筐体１１には、ディスプレイ１２、操作キー１３、専用キー１４、マイク１５、レシーバ１６、プロジェクタ３４が設けられている。 The mobile electronic device 10a is a mobile phone having a wireless communication function. The mobile electronic device 10a is a straight mobile phone in which each part is housed in a single box-shaped housing 11. The housing 11 is provided with a display 12, operation keys 13, dedicated keys 14, a microphone 15, a receiver 16, and a projector 34.
　次に、図１３は、図１２に示す携帯電子機器の機能の概略構成を示すブロック図である。図１３に示すように携帯電子機器１０ａは、制御部２２と、記憶部２４と、送受信部２６と、操作部２８と、音声処理部３０と、表示部３２と、プロジェクタ３４と、加速度センサ３６と、バッテリ４０と、充電部４２と、外部電源検出部４４と、充電台検出部４６と、を有する。なお、上述では、説明を省略したが、携帯電子機器１０もバッテリ４０等を備えている。また、制御部２２と、記憶部２４と、送受信部２６と、操作部２８と、音声処理部３０と、表示部３２と、プロジェクタ３４と、加速度センサ３６とについては、携帯電子機器１０と同様の構成であるので、説明を省略する。 Next, FIG. 13 is a block diagram showing a schematic configuration of functions of the portable electronic device shown in FIG. As shown in FIG. 13, the mobile electronic device 10 a includes a control unit 22, a storage unit 24, a transmission / reception unit 26, an operation unit 28, an audio processing unit 30, a display unit 32, a projector 34, and an acceleration sensor 36. And a battery 40, a charging unit 42, an external power source detection unit 44, and a charging stand detection unit 46. In addition, although description was abbreviate | omitted in the above, the portable electronic device 10 is also provided with the battery 40 grade | etc.,. The control unit 22, the storage unit 24, the transmission / reception unit 26, the operation unit 28, the sound processing unit 30, the display unit 32, the projector 34, and the acceleration sensor 36 are the same as those of the portable electronic device 10. Since it is the structure of this, description is abbreviate | omitted.
　バッテリ４０は、充電可能な二次電池であり、蓄電された電力を制御部２２に供給し、携帯電子機器１０ａの各部を作動させる。充電部４２は、バッテリ４０の電力の残量や、外部電源検出部４４及び充電台検出部４６の検出結果に基づいて、充電動作を制御する。 The battery 40 is a rechargeable secondary battery, supplies the stored power to the control unit 22, and operates each part of the portable electronic device 10a. The charging unit 42 controls the charging operation based on the remaining amount of power of the battery 40 and the detection results of the external power source detection unit 44 and the charging stand detection unit 46.
　外部電源検出部４４は、外部電源端子６４からバッテリ４０を含む携帯電子機器１０ａに電力が供給できる状態であるか、つまり、外部電源と接続された外部電源端子６４が携帯電子機器１０ａに接続されているかを検出するセンサである。外部電源検出部４４としては、例えば、外部電源端子６４とバッテリ４０との間の電線の間に配置され、電線に流れる電流、電圧を検出するセンサを用いることができる。外部電源検出部４４は、検出結果を制御部２２及び充電部４２に送る。なお、外部電源検出部４４は、電力の供給経路に関係なく、外部電源からバッテリ４０を含む携帯電子機器１０ａに電力が供給されているかを検出する。したがって、外部電源検出部４４は、外部電源端子６４と充電台６２を介して供給されているか、外部電源端子６４が携帯電子機器１０ａに直接接続されて外部電力が供給されているか、また、外部電源がＡＣアダプタ、コンセント等を介して電力を取得するものであるか、外部電源が蓄電池から電力を取得するものであるかにかかわらず、外部電源からバッテリ４０を含む携帯電子機器１０ａに電力が供給されているかを検出する。 The external power supply detection unit 44 is in a state where power can be supplied from the external power supply terminal 64 to the portable electronic device 10a including the battery 40, that is, the external power supply terminal 64 connected to the external power supply is connected to the portable electronic device 10a. It is a sensor that detects whether or not As the external power supply detection unit 44, for example, a sensor that is disposed between the electric wires between the external power supply terminal 64 and the battery 40 and detects current and voltage flowing through the electric wires can be used. The external power supply detection unit 44 sends the detection result to the control unit 22 and the charging unit 42. The external power supply detection unit 44 detects whether power is supplied from the external power supply to the portable electronic device 10a including the battery 40 regardless of the power supply path. Therefore, the external power supply detection unit 44 is supplied via the external power supply terminal 64 and the charging stand 62, whether the external power supply terminal 64 is directly connected to the portable electronic device 10a and supplied with external power, Regardless of whether the power source acquires power through an AC adapter, an outlet, or the like, or the external power source acquires power from the storage battery, power is transmitted from the external power source to the portable electronic device 10a including the battery 40. Detect if it is being supplied.
　充電台検出部４６は、筐体１１が充電台６２の所定位置に所定の姿勢で載置（または支持）されているかを検出する。充電台検出部４６としては、筐体１１と充電台６２とが接触していることを検出する接触センサ等を用いることができる。また、充電台検出部４６は、筐体１１の凹凸部と、充電台６２の凹凸部とが接触し、その凹凸が噛合う位置において、両部材の接触を検出することが好ましい。これにより、充電台検出部４６は、筐体１１が、机等の他の部材に支持されているか、充電台６２に支持されているかを判定すること、また、所定の姿勢で支持されているかを判定することができる。携帯電子機器１０ａは、基本的に以上のような構成である。 The charging stand detection unit 46 detects whether the casing 11 is placed (or supported) at a predetermined position on the charging stand 62 in a predetermined posture. As the charging stand detection part 46, the contact sensor etc. which detect that the housing | casing 11 and the charging stand 62 are contacting can be used. Moreover, it is preferable that the charging stand detection part 46 detects the contact of both members in the position where the uneven part of the housing | casing 11 and the uneven part of the charging stand 62 contact, and the unevenness | corrugation meshes | engages. Thereby, the charging stand detection part 46 determines whether the housing | casing 11 is supported by other members, such as a desk, or the charging stand 62, and is it supported by the predetermined attitude | position? Can be determined. The portable electronic device 10a is basically configured as described above.
　図１２に戻り携帯ユニット１の説明を続ける。充電台６２は、上述したように携帯電子機器１０ａを支持する支持部材である。充電台６２には、レンズ部６６と、ファン６８とが設けられている。レンズ部６６は、携帯電子機器１０ａを載置した時に、携帯電子機器１０ａの光射出部３４ａと対面する位置に設けられている。レンズ部６６は、光射出部３４ａから射出された光の広角（照射画角）をより広げる拡大レンズである。以下、図１４を用いて説明する。ここで、図１４は、図１２に示す携帯電子機器で画像を表示させている他の状態を示す説明図である。図１４に示すように、携帯電子機器１０ａを充電台６２に載置すると、プロジェクタ３４の光射出部３４ａとレンズ部６６とが対面する状態となる。この状態で、プロジェクタ３４により画像の投影を行うと、図１４に示すように、レンズ部６６を通過させない場合（つまりレンズ部６６がないと仮定した場合）に投影される光の投影領域（照射範囲）Ａよりも広い領域である投影領域Ｂの範囲に画像を投影させることができる。つまり、レンズ部６６を通過させることで、投影面（照射面）により大きい画像を投影することができる。なお、レンズ部６６としては、屈折率、焦点距離が固定されたレンズを用いてもよいが、屈折率、焦点距離を変化させることができるズームレンズを用いることが好ましい。ズームレンズを用いることで、光の照射領域を調整することができる。 Returning to FIG. 12, the description of the mobile unit 1 is continued. The charging stand 62 is a support member that supports the portable electronic device 10a as described above. The charging stand 62 is provided with a lens portion 66 and a fan 68. The lens unit 66 is provided at a position facing the light emitting unit 34a of the portable electronic device 10a when the portable electronic device 10a is placed. The lens unit 66 is a magnifying lens that further widens the wide angle (irradiation field angle) of the light emitted from the light emitting unit 34a. Hereinafter, a description will be given with reference to FIG. Here, FIG. 14 is an explanatory diagram showing another state in which an image is displayed on the portable electronic device shown in FIG. As shown in FIG. 14, when the portable electronic device 10 a is placed on the charging stand 62, the light emitting unit 34 a and the lens unit 66 of the projector 34 face each other. When an image is projected by the projector 34 in this state, as shown in FIG. 14, a projection area (irradiation) of light projected when the lens unit 66 is not passed (that is, when there is no lens unit 66), as shown in FIG. The image can be projected in the range of the projection area B which is an area wider than (range) A. That is, by passing through the lens unit 66, a larger image can be projected onto the projection surface (irradiation surface). As the lens unit 66, a lens having a fixed refractive index and focal length may be used, but a zoom lens capable of changing the refractive index and the focal length is preferably used. By using the zoom lens, the light irradiation area can be adjusted.
　ファン６８は、レンズ部６６の近傍に配置されており、充電台６２の所定位置に載置（搭載）された携帯電子機器１０ａのプロジェクタ３４に送風し、プロジェクタ３４を冷却する。なお、ファン６８は、プロジェクタ３４の近傍の空気を吸引し、携帯電子機器１０ａから離れる方向に空気を排出することで、プロジェクタ３４の周辺の空気を入れ替えて、プロジェクタ３４を冷却するようにしても、プロジェクタ３４に空気を吹き付けることで、プロジェクタ３４を冷却するようにしてもよい。 The fan 68 is disposed in the vicinity of the lens unit 66, and blows air to the projector 34 of the portable electronic device 10 a placed (mounted) at a predetermined position of the charging stand 62 to cool the projector 34. The fan 68 sucks air in the vicinity of the projector 34 and discharges air in a direction away from the portable electronic device 10a, so that the air around the projector 34 is replaced and the projector 34 is cooled. The projector 34 may be cooled by blowing air onto the projector 34.
　また、外部電源端子６４は、上述したように、一方の端部が充電台６２と接続され、他方の端部が外部電源と接続された端子である。なお、本実施例では、外部電源端子６４を充電台６２に接続させたが、外部電源端子６４は、携帯電子機器１０ａと直接接続することも可能である。具体的には、筐体１１に外部電源端子６４と接続するための端子を設けることで、充電台６２を介することなく、外部電源端子６４と携帯電子機器１０ａとを接続させることができる。携帯ユニット１は、以上のような構成である。 Further, as described above, the external power supply terminal 64 is a terminal having one end connected to the charging stand 62 and the other end connected to an external power supply. In this embodiment, the external power supply terminal 64 is connected to the charging stand 62, but the external power supply terminal 64 can also be directly connected to the portable electronic device 10a. Specifically, by providing a terminal for connecting to the external power supply terminal 64 in the housing 11, it is possible to connect the external power supply terminal 64 and the portable electronic device 10 a without using the charging stand 62. The portable unit 1 is configured as described above.
　次に、図１５を用いて携帯ユニット１及び携帯電子機器１０ａの動作を説明する。ここで、図１５は、携帯電子機器の制御の一例を示す説明図である。図１５に示す説明図は、横軸方向の項目が、携帯電子機器の状態を示す項目であり、縦軸方向の項目が、プロジェクタの制御モードを示す項目である。図１５に示す説明図では、それぞれの携帯電子機器の状態のときに、選択可能な制御モードを○で示し、選択できない制御モードを×で示す。 Next, operations of the mobile unit 1 and the mobile electronic device 10a will be described with reference to FIG. Here, FIG. 15 is an explanatory diagram illustrating an example of control of the mobile electronic device. In the explanatory diagram shown in FIG. 15, the item in the horizontal axis direction is an item indicating the state of the portable electronic device, and the item in the vertical axis direction is an item indicating the control mode of the projector. In the explanatory view shown in FIG. 15, in the state of each portable electronic device, selectable control modes are indicated by ◯, and control modes that cannot be selected are indicated by ×.
　携帯電子機器の状態を示す項目について説明する。バッテリ駆動時とは、外部電源検出部４４で外部電源との接続が検出されず、充電台検出部４６で充電台６２との接触が検出されていない状態である。つまり、携帯電子機器１０ａが充電台６２に載置されておらず、かつ、外部からの電力供給がなく、バッテリ４０に蓄電されている電力で各部が駆動されている状態である。次に、外部電源接続時とは、外部電源検出部４４で外部電源との接続が検出され、充電台検出部４６で充電台６２との接触が検出されていない状態である。つまり、携帯電子機器１０ａが充電台６２に載置されておらず、外部から供給された電力で各部が駆動されている状態である。次に、充電台搭載時とは、外部電源検出部４４で外部電源との接続が検出され、充電台検出部４６で充電台６２との接触が検出されている状態である。つまり、携帯電子機器１０ａが充電台６２に載置され、かつ、外部から供給された電力で各部が駆動されている状態である。 The items indicating the state of the portable electronic device will be described. When the battery is driven, the external power supply detection unit 44 does not detect the connection with the external power supply, and the charging stand detection unit 46 does not detect the contact with the charging stand 62. That is, the portable electronic device 10 a is not placed on the charging stand 62, and there is no external power supply, and each part is driven by the power stored in the battery 40. Next, when the external power supply is connected, the external power supply detection unit 44 detects the connection with the external power supply, and the charging stand detection unit 46 does not detect the contact with the charging stand 62. That is, the portable electronic device 10a is not placed on the charging stand 62, and each unit is driven by power supplied from the outside. Next, when the charging stand is mounted, the external power supply detection unit 44 detects the connection with the external power supply, and the charging stand detection unit 46 detects the contact with the charging stand 62. That is, the portable electronic device 10a is placed on the charging stand 62, and each part is driven by electric power supplied from the outside.
　次に、図１５に示すプロジェクタの制御モードについて説明する。まず、基本モードとして、携帯モードと据え置きモードがある。携帯モード（第１のモード）は、操作者が携帯電子機器１０ａ（筐体１１）を持っている状態でプロジェクタ３４を使用することを想定した制御モードであり、据え置きモード（第２のモード）は、操作者が携帯電子機器１０ａ（筐体１１）を机や、台や、充電台に置いた状態でプロジェクタ３４を使用することを想定した制御モードである。携帯モードと据え置きモードの制御方法は、後ほど、具体例とともに説明する。 Next, the projector control mode shown in FIG. 15 will be described. First, there are a portable mode and a stationary mode as basic modes. The portable mode (first mode) is a control mode that assumes that the operator uses the projector 34 while holding the portable electronic device 10a (housing 11), and is a stationary mode (second mode). Is a control mode in which it is assumed that the operator uses the projector 34 with the portable electronic device 10a (housing 11) placed on a desk, a stand, or a charging stand. A method for controlling the portable mode and the stationary mode will be described later with specific examples.
　次に、安全性に掛かる制御モードとしては、自動的制御モードと能動的制御モードがある。自動的制御モードとは、制御部２２が予め設定された制御条件に基づいてプロジェクタ３４の投影の制御を行うモードであり、能動的制御モードとは、操作者の操作が入力された場合のみプロジェクタ３４の投影を行うモードである。つまり、能動的制御モードでは、ユーザが積極的に操作を行っている場合（つまり、投影許可の信号を入力している場合）のみ、プロジェクタ３４による画像の投影を行う制御モードである。なお、以下で説明する携帯モードと据え置きモードでは、携帯モードが能動的制御モードを含み、据え置きモードが自動的制御モードを含む。 Next, safety control modes include automatic control mode and active control mode. The automatic control mode is a mode in which the control unit 22 controls the projection of the projector 34 based on preset control conditions, and the active control mode is the projector only when an operator's operation is input. In this mode, 34 projections are performed. That is, the active control mode is a control mode in which the projector 34 projects an image only when the user is actively performing an operation (that is, when a projection permission signal is input). In the portable mode and the stationary mode described below, the portable mode includes an active control mode, and the stationary mode includes an automatic control mode.
　次に、機能に掛かる制御モードは、他の制御モードよりも消費電力が大きくなる制御モード、他の制御モードよりも高い安全性が必要となる制御モードであり、例えば、シアターモード、プロジェクティブアラームモード、フォトフレームモード、ファンモードがある。 Next, the control mode related to the function is a control mode in which power consumption is larger than in other control modes, and a control mode in which higher safety is required than in other control modes. For example, theater mode, projective alarm Mode, photo frame mode, and fan mode.
　シアターモードは、プロジェクタ３４から射出する光量を他の制御モード、具体的には光量を特に調整しないで画像を投影する制御モードよりも高くする制御モードである。シアターモードは、より明るい画像を投影させることができる。 The theater mode is a control mode in which the amount of light emitted from the projector 34 is set higher than other control modes, specifically, the control mode in which an image is projected without particularly adjusting the amount of light. In the theater mode, a brighter image can be projected.
　プロジェクティブアラームモードは、目覚ましのため、出発時刻を知らせるため等で、予め設定されている時間にアラームを出力するモードで、音声、または、バイブレーションの発生とともに、プロジェクタ３４から光を出力させる制御モードである。プロジェクティブアラームモードの制御については、後ほど説明する。 The projective alarm mode is a mode in which an alarm is output at a preset time, such as for alarming or informing the departure time, and a control mode in which light is output from the projector 34 along with the occurrence of sound or vibration. It is. The control of the projective alarm mode will be described later.
　フォトフレームモードは、記憶部２４等に記憶されている複数の画像データをプロジェクタ３４により順次投影させる制御モードである。 The photo frame mode is a control mode in which the projector 34 sequentially projects a plurality of image data stored in the storage unit 24 or the like.
　ファンモードは、ファン６８を駆動させ、携帯電子機器１０ａのプロジェクタ３４を冷却させる制御モードである。なお、携帯電子機器１０ａと充電台６２との間に、情報の送受信を行う端子を設けておくことで、制御部２２は、ファン６８の動作を制御することができる。また、ファン６８の制御は、充電台に別の制御部を設け、別の制御部で制御してもよい。 The fan mode is a control mode in which the fan 68 is driven and the projector 34 of the portable electronic device 10a is cooled. In addition, the control part 22 can control the operation | movement of the fan 68 by providing the terminal which transmits / receives information between the portable electronic device 10a and the charging stand 62. FIG. Further, the fan 68 may be controlled by providing another control unit on the charging stand and controlling by another control unit.
　なお、基本モード、安全性に掛かる制御モードは、それぞれ、２つの制御モードのうち１つの制御モードを選択する必要がある（つまり、携帯モードと据え置きモードを同時に駆動することはできない）が、機能に掛かるモードは、複数の制御モードを同時駆動させることができる。 Note that the basic mode and the control mode related to safety need to select one of the two control modes (that is, the portable mode and the stationary mode cannot be driven simultaneously). As for the mode applied to, a plurality of control modes can be driven simultaneously.
　ここで、携帯電子機器１０ａは、図１５に示すように、バッテリ駆動時か、外部電源接続時か、充電台搭載時かで、選択可能な制御モードを切り替える。具体的には、バッテリ駆動時には、携帯モードと能動的制御モードのみ選択可能で、他の制御モードは、選択不可能とする。また、外部電源接続時には、基本モードと安全性に関する制御モードは選択可能とし、機能に関する制御モードは選択不可能にする。また、充電台搭載時には、基本モードと、安全性に関する制御モードと、機能に関する制御モードのいずれも選択可能とする。 Here, as shown in FIG. 15, the portable electronic device 10 a switches the selectable control mode depending on whether it is driven by a battery, connected to an external power source, or mounted on a charging stand. Specifically, when the battery is driven, only the portable mode and the active control mode can be selected, and the other control modes cannot be selected. When an external power supply is connected, the basic mode and the control mode related to safety can be selected, and the control mode related to functions cannot be selected. When the charging stand is mounted, any of a basic mode, a safety control mode, and a function control mode can be selected.
　このように、制御部２２は、外部電源検出部４４と充電台検出部４６との検出結果に基づいて、携帯電子機器１０ａの状態を検出し、その検出結果に基づいて選択できる制御モードを切り替えることで、携帯電子機器１０ａの状態に応じて、プロジェクタ３４の動作を適切に切り替えることができる。 As described above, the control unit 22 detects the state of the portable electronic device 10a based on the detection results of the external power supply detection unit 44 and the charging stand detection unit 46, and switches the control mode that can be selected based on the detection result. Thus, the operation of the projector 34 can be appropriately switched according to the state of the portable electronic device 10a.
　具体的には、充電台搭載時のみ、機能に関する制御モードを選択可能とすることで、高い安全性を維持しつつ、種々の制御を行うことが可能となる。ここで、充電台搭載時は、外部から電力が供給され、かつ、充電台６２に支持された状態であるため、消費電力が大きい、充電台６２が必要となる、画像の投影位置、方向の変化を抑制する必要がある制御モードを選択しても、高い安全性を維持しつつ、好適に動作させることができる。また、充電台搭載時以外は、これらの制御モードが選択できないようにすることで、携帯電子機器１０ａを長時間、安全に使用することができる。 Specifically, by making it possible to select a control mode related to a function only when the charging stand is installed, various controls can be performed while maintaining high safety. Here, when the charging stand is mounted, since power is supplied from the outside and supported by the charging stand 62, the power consumption is large, the charging stand 62 is required, the projected position and direction of the image Even if a control mode that needs to suppress the change is selected, it can be suitably operated while maintaining high safety. Further, by prohibiting these control modes from being selected except when the charging stand is mounted, the portable electronic device 10a can be used safely for a long time.
　例えば、シアターモードは、光量を多くするため、消費電力が大きくなるが、外部から電力が供給されているため、消費電力が大きくても画像を投影し続けることができる。また、より光量を大きくし、かつ、レンズ部６６を通過して画像を投影できるため、より大きくて明るい画像を投影することが可能となる。また、充電台６２に支持しているので、投影方向が変化する可能性が低いため、プロジェクタ３４から射出された光が不意に人に向かって照射される可能性を低くすることができる。これにより、光量を高くしても、また、照射画角を大きくしても、安全性を高く維持することができる。 For example, in the theater mode, power consumption increases because the amount of light increases, but since power is supplied from the outside, it is possible to continue projecting images even when power consumption is large. Further, since the amount of light can be increased and an image can be projected through the lens unit 66, a larger and brighter image can be projected. Moreover, since it is supported by the charging stand 62, it is unlikely that the projection direction will change, so that the possibility that the light emitted from the projector 34 is unexpectedly irradiated toward a person can be reduced. As a result, safety can be maintained high even when the amount of light is increased or the field angle of view is increased.
　また、プロジェクティブアラームモードも、アラーム機能の動作時に、プロジェクタ３４により光を射出することで、音声、振動のみならず、視覚にも刺激が与えられ、より確実にアラームに気づくことができる。また、メッセージを表示させることで、アラームにより通知する内容を瞬時に認識することが可能となる。また、充電台搭載時のみ実行可能とすることで、上述したように、投影位置をずれにくくすることができ、安全性を高く維持することができる。 Also, in the projective alarm mode, when the alarm function is activated, light is emitted by the projector 34, so that not only voice and vibration but also vision is stimulated and the alarm can be noticed more reliably. Further, by displaying a message, it is possible to instantly recognize the content notified by the alarm. Moreover, by making it possible to execute only when the charging stand is mounted, it is possible to make it difficult to shift the projection position as described above, and it is possible to maintain high safety.
　また、フォトフレームモードでは、操作者が停止するまで、または設定により終了するまで、連続して画像を投影するモードであるが、外部電力から電力が供給されることで、バッテリの残量によらず長時間連続して画像を投影することができる。また、充電台搭載時のみ選択可能とすることで、バッテリに蓄えられた電力が消費され、携帯電子機器１０ａが使用不可能になることを抑制することができる。また、充電台搭載時のみ実行可能とすることで、上述したように、投影位置をずれにくくすることができ、長時間連続して光を投影した場合でも、安全性を高く維持することができる。 The photo frame mode is a mode in which images are continuously projected until the operator stops or finishes the setting. However, depending on the remaining battery level, power is supplied from external power. The image can be projected continuously for a long time. In addition, by making the selection possible only when the charging stand is mounted, it is possible to suppress the power stored in the battery from being consumed and the portable electronic device 10a from becoming unusable. Moreover, by making it possible to execute only when the charging stand is mounted, the projection position can be made difficult to shift as described above, and high safety can be maintained even when light is projected continuously for a long time. .
　また、ファンモードでは、プロジェクタ３４を冷却することができ、長時間、また、高出力で画像を投影させた場合でも、プロジェクタ３４が高温になりすぎて、性能が低下することを抑制することができる。なお、ファンモードは、上述した他の機能モードとともに動作させることが好ましい。なお、機能に関する制御モードは、上記制御モードに限定されず、種々の制御モードを用いることができる。 Further, in the fan mode, the projector 34 can be cooled, and even when an image is projected for a long time or at a high output, the projector 34 is prevented from becoming too hot and performance can be suppressed. it can. The fan mode is preferably operated together with the other function modes described above. In addition, the control mode regarding a function is not limited to the said control mode, A various control mode can be used.
　次に、図１６を用いて、アラーム動作の一例を説明する。ここで、図１６は、携帯電子機器の動作の一例を示すフロー図である。まず、携帯電子機器１０ａには、所定の時刻にアラーム動作を行うように設定されている。制御部２２は、時刻情報を取得し、ステップＳ１０ａ２として、アラーム動作の××秒前であることを検出したら、ステップＳ１０ａ４として、携帯電子機器１０ａの状態は何かを判定する。つまり、制御部２２は、ステップＳ１０ａ４として、携帯電子機器１０ａが、バッテリ駆動時か、外部電源接続時か、充電台搭載時のいずれの状態であるかを判定する。なお、制御部２２は、ステップＳ１０ａ４として、携帯電子機器１０ａが、充電台搭載時であるか否かを判定してもよい。 Next, an example of an alarm operation will be described with reference to FIG. Here, FIG. 16 is a flowchart showing an example of the operation of the portable electronic device. First, the mobile electronic device 10a is set to perform an alarm operation at a predetermined time. When the control unit 22 acquires time information and detects that it is xx seconds before the alarm operation as step S10a2, the control unit 22 determines what the state of the portable electronic device 10a is as step S10a4. That is, the control unit 22 determines in step S10a4 whether the portable electronic device 10a is in a state of being driven by a battery, connected to an external power source, or mounted on a charging stand. In addition, the control part 22 may determine whether the portable electronic device 10a is at the time of charging stand mounting as step S10a4.
　制御部２２は、ステップＳ１０ａ４で、バッテリ駆動時または外部電源接続時である、つまり、充電台搭載時ではないと判定したら、ステップＳ１０ａ６として、プロジェクタの機能モード無し、と判定し、ステップＳ１１０ａに進む。つまり、制御部２２は、機能モードの選択不可能（具体的には、プロジェクティブアラームモードの作動不可能）と判定して、ステップＳ１１０ａに進む。 If it is determined in step S10a4 that the battery is being driven or the external power supply is connected, that is, not the charging base is mounted, the control unit 22 determines that the projector has no functional mode as step S10a6, and proceeds to step S110a. . That is, the control unit 22 determines that the function mode cannot be selected (specifically, the projective alarm mode cannot be operated), and proceeds to step S110a.
　また、制御部２２は、ステップＳ１０ａ４で、携帯電子機器１０ａの状態が、充電台搭載時である、つまり、バッテリ駆動時及び外部電源接続時ではないと判定したら、ステップＳ１０ａ８として、プロジェクティブアラームモードであるかを判定する。つまり、アラーム動作をプロジェクティブアラームモードで行うように設定されているかを判定する。 If the control unit 22 determines in step S10a4 that the state of the portable electronic device 10a is when the charging base is mounted, that is, not when the battery is driven or when an external power source is connected, as step S10a8, the projective alarm mode is set. It is determined whether it is. That is, it is determined whether the alarm operation is set to be performed in the projective alarm mode.
