　近年、ノート型パソコン（以下、ノートＰＣと呼ぶ）においては、タブレット型パソコンとしても使用できるコンバーチブル型のノートＰＣが普及している。通常のノートＰＣでは、キーボードなどを有する筐体と、ディプレイ部を有する筐体とがヒンジなどを介して接続され、ヒンジを中心に筐体が１８０度程度開くようになっている。これに対し、コンバーチブル型のノートＰＣは、タッチパネルを配置したディプレイ部を有する筐体がヒンジを中心に３６０度回転可能である。そして、タブレット型として使用する場合は、タッチパネルを配設したディプレイ部を有する筐体を３６０度回転し、裏返して使用する。 2. Description of the Related Art In recent years, convertible notebook PCs that can also be used as tablet PCs have become widespread in notebook PCs (hereinafter referred to as notebook PCs). In a normal notebook PC, a housing having a keyboard or the like and a housing having a display unit are connected via a hinge or the like, and the housing opens about 180 degrees around the hinge. On the other hand, in the convertible notebook PC, a housing having a display unit on which a touch panel is disposed can be rotated 360 degrees around a hinge. And when using as a tablet type, the housing | casing which has a display part which arrange | positioned the touch panel is rotated 360 degree, and it turns over and uses it.
　コンバーチブル型のノートＰＣをタブレット型として使用する場合、タッチパネルを配設したディスプレイの大画面化とそれに伴う狭額縁化により、利用者が外周部分を把持した際に誤ってタッチパネル部分まで指が触れてしまい、誤操作することがある。 When a convertible notebook PC is used as a tablet type, the user touches the touch panel portion by mistake when the user grips the outer peripheral portion due to the increase in screen size of the display provided with the touch panel and the accompanying narrowing of the frame It may cause misoperation.
　このような誤操作を防止する従来技術として、タッチパネルを囲う枠体への接触を検出する検出部を複数箇所に備え、複数の検出部が接触を検出した場合に、受け付けを無効にするタッチパネル装置が知られている。また、表示部の有効表示領域に対応する第１の検出領域と、第１の検出領域の周囲を囲う第２の検出領域とをタッチパネルが有し、第２の検出領域での座標入力を検出した場合に、第１の検出領域の一部または全部を座標入力を無効とする情報入力装置も知られている。 As a prior art for preventing such an erroneous operation, a touch panel device is provided with a plurality of detection units that detect contact with a frame surrounding a touch panel, and in which the reception is invalidated when the plurality of detection units detect contact. Are known. The touch panel has a first detection area corresponding to the effective display area of the display unit and a second detection area surrounding the periphery of the first detection area, and detects coordinate input in the second detection area. There is also known an information input device in which coordinate input is invalidated in part or all of the first detection area.

　しかしながら、上記の従来技術では、コンバーチブル型のノートＰＣをタブレット型として使用する場合のタッチパネルにおける誤検知の抑止を、狭額縁化を損なうことなく簡易に行うことは困難である。 However, in the above-described conventional technology, it is difficult to easily suppress erroneous detection in a touch panel in the case of using a convertible notebook PC as a tablet, without impairing the narrowing of the frame.
　例えば、タッチパネルにおける誤検知のために第１の検出領域の周囲を囲う第２の検出領域を設ける場合は、狭額縁化には不利となる。また、タッチパネルを囲う枠体への接触を検出する検出部を複数設ける場合は、新たに接触センサーを配置するなど、部品が増える複雑な構成となる。 For example, in the case where a second detection area surrounding the periphery of the first detection area is provided for erroneous detection in the touch panel, it is disadvantageous to narrow the frame. Further, in the case where a plurality of detection units for detecting contact with the frame surrounding the touch panel are provided, a contact sensor is newly provided, which results in a complicated configuration in which parts are increased.
　１つの側面では、簡易にタッチパネルにおける誤検知を抑止することができる情報処理装置および検出方法を提供することを目的とする。 In one aspect, it is an object of the present invention to provide an information processing apparatus and a detection method that can easily suppress erroneous detection in a touch panel.
　第１の案では、情報処理装置は、表面に第１の入力部を備えた第１の筐体と、表面に第２の入力部を備えた第２の筐体と、状態検出部と、入力検出部とを有する。状態検出部は、第１の筐体の裏面と、第２の筐体の裏面とが向かい合う位置に位置するかを判断する。入力検出部は、状態検出部が第１の筐体の裏面と、第２の筐体の裏面とが向かい合う位置に位置すると判断すると、第２の入力部に対する入力が行われている間、第１の入力部の外周部分に対する入力は非検出とする。 In the first scheme, the information processing apparatus includes a first case having a first input unit on the surface, a second case having a second input unit on the surface, and a state detection unit. And an input detection unit. The state detection unit determines whether the back surface of the first housing and the back surface of the second housing face each other. When the input detection unit determines that the state detection unit is positioned at a position where the back surface of the first housing and the back surface of the second housing face each other, while the input to the second input unit is being performed, The input to the outer peripheral portion of the input unit 1 is not detected.
　本発明の１実施態様によれば、簡易にタッチパネルにおける誤検知をすることができる。 According to one embodiment of the present invention, false detection in the touch panel can be easily performed.

　以下、図面を参照して、実施形態にかかる情報処理装置および検出方法を説明する。実施形態において同一の機能を有する構成には同一の符号を付し、重複する説明は省略する。なお、以下の実施形態で説明する情報処理装置および検出方法は、一例を示すに過ぎず、実施形態を限定するものではない。また、以下の各実施形態は、矛盾しない範囲内で適宜組みあわせてもよい。 Hereinafter, an information processing apparatus and a detection method according to an embodiment will be described with reference to the drawings. The components having the same functions in the embodiments are denoted by the same reference numerals, and the redundant description will be omitted. Note that the information processing apparatus and the detection method described in the following embodiments are merely an example, and the embodiments are not limited. In addition, each of the following embodiments may be appropriately combined within the scope of no contradiction.
（第１の実施形態）
　図１、２は、第１の実施形態にかかる情報処理装置の外観を説明する説明図である。図１に示すように、情報処理装置１は、下部筐体２と上部筐体３とがヒンジ４を介して接続され、ヒンジ４を中心に下部筐体２と上部筐体３とが３６０度程度開くようになっているコンバーチブル型のノートＰＣである。 First Embodiment
1 and 2 are explanatory diagrams for explaining the appearance of the information processing apparatus according to the first embodiment. As shown in FIG. 1, in the information processing apparatus 1, the lower housing 2 and the upper housing 3 are connected via the hinge 4, and the lower housing 2 and the upper housing 3 are 360 degrees around the hinge 4. It is a convertible notebook PC that is designed to open to some extent.
　下部筐体２には、閉じた状態で上部筐体３と向き合う面（表面）に、キーボード５（ＫＢと称する場合がある）およびタッチパッド６（ＭＳと称する場合がある）が配置されている。同様に、上部筐体３には、閉じた状態で下部筐体２と向き合う面（表面）に、ＬＣＤパネル７と、ＬＣＤパネル７に重畳してタッチパネル８とが配置されている。 In the lower housing 2, a keyboard 5 (sometimes referred to as KB) and a touch pad 6 (sometimes referred to as MS) are disposed on the surface (surface) facing the upper housing 3 in the closed state. . Similarly, in the upper case 3, the LCD panel 7 and the touch panel 8 superimposed on the LCD panel 7 are disposed on the surface (surface) facing the lower case 2 in the closed state.
　このため、情報処理装置１は、下部筐体２と上部筐体３とを１２０度程度開いた状態でキーボード５およびタッチパッド６による入力操作を行いつつ、ＬＣＤパネル７の表示画面を確認する通常のノートＰＣとして使用可能である。 Therefore, the information processing apparatus 1 normally confirms the display screen of the LCD panel 7 while performing the input operation with the keyboard 5 and the touch pad 6 in a state where the lower housing 2 and the upper housing 3 are opened about 120 degrees. It can be used as a notebook PC.
　また、情報処理装置１は、下部筐体２と上部筐体３とを３６０度程度開いて互いの裏面同士を向かい合わせた状態（以下、タブレット状態）では、タッチパネル８による入力操作を行いつつ、ＬＣＤパネル７の表示画面を確認するタブレット型として使用可能である。 Further, the information processing apparatus 1 performs an input operation with the touch panel 8 in a state in which the lower housing 2 and the upper housing 3 are opened about 360 degrees and the back surfaces face each other (hereinafter, tablet state), It can be used as a tablet type for confirming the display screen of the LCD panel 7.
　なお、本実施形態では、下部筐体２と、上部筐体３とをヒンジ４を介して回転可能な構成を例示しているが、下部筐体２と、上部筐体３とは、ヒンジ４を介して着脱可能であってもよい。例えば、下部筐体２と上部筐体３とを１２０度程度開いた状態でヒンジ４に取り付けることで、通常のノートＰＣとして使用してもよい。また、下部筐体２の裏面と上部筐体３の裏面とを向かい合う位置にして互いに重ねた状態でヒンジ４に取り付けることでタブレット型として使用してもよい。 In the present embodiment, the lower housing 2 and the upper housing 3 are illustrated as being rotatable through the hinges 4, but the lower housing 2 and the upper housing 3 are hinges 4. It may be removable via For example, the lower case 2 and the upper case 3 may be used as a normal notebook PC by attaching the lower case 2 and the upper case 3 to the hinge 4 in an open state at about 120 degrees. Alternatively, the back surface of the lower housing 2 and the back surface of the upper housing 3 may be used as a tablet type by attaching them to the hinge 4 in a mutually overlapping position.
　図２に示すように、情報処理装置１がタブレット状態である場合は、第１の入力部の一例であるタッチパネル８のある上部筐体３の面を表面としたとき、第２の入力部の一例であるキーボード５およびタッチパッド６のある下部筐体２の面は裏面となる。すなわち、情報処理装置１がタブレット状態である場合は、タッチパネル８と、キーボード５およびタッチパッド６とは表裏の位置関係となる。 As shown in FIG. 2, when the information processing apparatus 1 is in the tablet state, when the surface of the upper case 3 having the touch panel 8 which is an example of the first input unit is a surface, the second input unit The surface of the lower housing 2 with the keyboard 5 and the touch pad 6 as an example is the back surface. That is, when the information processing apparatus 1 is in the tablet state, the touch panel 8 and the keyboard 5 and the touch pad 6 have a positional relationship of front and back.
　タブレット状態とした情報処理装置１を利用者が把持して使用する場合は、裏面を支える指などでキーボード５またはタッチパッド６を押下することがある。例えば、利用者が情報処理装置１の外周部分を把持して使用する場合は、外周部分にあるキーボード５のキーまたはタッチパッド６を指で押下することがある。 When the user holds and uses the information processing apparatus 1 in the tablet state, the keyboard 5 or the touch pad 6 may be pressed with a finger or the like supporting the back surface. For example, when the user holds and uses the outer peripheral portion of the information processing apparatus 1, the user may press the key of the keyboard 5 or the touch pad 6 in the outer peripheral portion with a finger.
　このようなタブレット状態とした場合における、ＬＣＤパネル７およびタッチパネル８の裏側にあるキーボード５またはタッチパッド６の入力操作を利用することで、情報処理装置１は、利用者が把持した際にタッチパネル８まで指が触れてしまうことによる誤検知を抑止する。具体的には、情報処理装置１は、タブレット状態の有無を検知し、タブレット状態を検知しているときに、裏面のキーボード５またはタッチパッド６に対する入力操作を検出している間、タッチパネル８の外周部分における入力操作を非検出とする。これにより、情報処理装置１は、ＬＣＤパネル７およびタッチパネル８の狭額縁化を実現しつつ、新たに接触センサーを配置するなどの構成を複雑にすることなく、簡易にタッチパネル８における誤検知を抑止することができる。 By using the input operation of the keyboard 5 or the touch pad 6 on the back side of the LCD panel 7 and the touch panel 8 in such a tablet state, the information processing apparatus 1 causes the touch panel 8 to be held by the user. Suppress false detection due to finger touching. Specifically, the information processing apparatus 1 detects the presence or absence of the tablet state, and while detecting the tablet state, while detecting the input operation to the keyboard 5 or the touch pad 6 on the back surface, The input operation in the outer peripheral portion is not detected. Thereby, the information processing apparatus 1 realizes the narrowing of the frame of the LCD panel 7 and the touch panel 8 while suppressing erroneous detection in the touch panel 8 easily without complicating the configuration such as arranging a new contact sensor. can do.
　図３は、第１の実施形態にかかる情報処理装置１の構成例を示すブロック図である。図３に示すように、情報処理装置１は、組み込みコントローラー１０、タッチパネル部２０、チップセット３０、ＬＣＤパネル７、ストレージ４０、キーボード部５０および加速度センサー６１、６２を有する。 FIG. 3 is a block diagram showing an exemplary configuration of the information processing apparatus 1 according to the first embodiment. As shown in FIG. 3, the information processing apparatus 1 includes a built-in controller 10, a touch panel unit 20, a chipset 30, an LCD panel 7, a storage 40, a keyboard unit 50 and acceleration sensors 61 and 62.
　組み込みコントローラー１０は、加速度処理部１１、キーボードコントローラー１２（ＫＢＣ）およびＩ２Ｃコントローラー１３を有する。加速度処理部１１は、加速度センサー６１、加速度センサー６２と接続される。 The embedded controller 10 has an acceleration processing unit 11, a keyboard controller 12 (KBC) and an I2C controller 13. The acceleration processing unit 11 is connected to an acceleration sensor 61 and an acceleration sensor 62.
　加速度センサー６１は、キーボード部５０を有する下部筐体２に設置され、キーボード部５０にかかる加速度を計測するセンサーである。加速度センサー６２は、タッチパネル部２０を有する上部筐体３に設置され、タッチパネル部２０にかかる加速度を計測するセンサーである。そして、加速度センサー６１、６２は、情報処理装置１がタブレット状態となったときに、Ｘ、Ｙ、Ｚ方向の極性が一致するように配置される。理想的には、情報処理装置１がタブレット状態となったときに、加速度センサー６１、６２の双方が同じ値を検出値として出力する。 The acceleration sensor 61 is a sensor that is installed in the lower housing 2 having the keyboard unit 50 and measures the acceleration applied to the keyboard unit 50. The acceleration sensor 62 is a sensor that is installed in the upper case 3 having the touch panel unit 20 and measures the acceleration applied to the touch panel unit 20. The acceleration sensors 61 and 62 are arranged such that the polarities in the X, Y, and Z directions coincide with each other when the information processing apparatus 1 is in the tablet state. Ideally, when the information processing apparatus 1 is in the tablet state, both of the acceleration sensors 61 and 62 output the same value as a detection value.
　加速度処理部１１は、加速度センサー６１、加速度センサー６２による検知結果をもとに、情報処理装置１がタブレット状態であるか否かを検出する。具体的には、加速度処理部１１は、加速度センサー６１、６２それぞれの検出値（Ｘ、Ｙ、Ｚ方向の加速度）を監視し、互いの検出値の差分が一定の閾値以内になった場合に、タブレット状態であると検出する。すなわち、加速度処理部１１は、状態検出部の一例である。 The acceleration processing unit 11 detects whether or not the information processing apparatus 1 is in the tablet state based on the detection results of the acceleration sensor 61 and the acceleration sensor 62. Specifically, the acceleration processing unit 11 monitors detection values (accelerations in the X, Y, and Z directions) of the acceleration sensors 61 and 62, respectively, and the difference between the detection values is within a certain threshold. , Detects that it is in the tablet state. That is, the acceleration processing unit 11 is an example of a state detection unit.
　なお、タブレット状態であるか否かの検出について、加速度センサー６１、６２による検知結果に基づく方法は一例であり、他の方法を用いてもよい。例えば、下部筐体２と上部筐体３との回転角度を検知する角度センサー（図示しない）をヒンジ４に設置する。そして、加速度処理部１１の代わりに設けた角度処理部（図示しない）は、角度センサーの検知結果をもとに、回転角度が約３６０度となるタブレット状態を検出してもよい。また、下部筐体２および上部筐体３の一方にはマグネット（図示しない）を配置し、他方にはタブレット状態になった場合にマグネットの磁力を検出可能とする位置に磁気センサー（図示しない）を配置する。そして、加速度処理部１１の代わりに設けた磁気処理部（図示しない）は、磁気センサーの検知結果をもとにタブレット状態を検出してもよい。 In addition, the method based on the detection result by the acceleration sensors 61 and 62 is an example about detection of whether it is a tablet state, and another method may be used. For example, an angle sensor (not shown) for detecting the rotational angle between the lower housing 2 and the upper housing 3 is installed on the hinge 4. Then, an angle processing unit (not shown) provided instead of the acceleration processing unit 11 may detect a tablet state in which the rotation angle is approximately 360 degrees based on the detection result of the angle sensor. In addition, a magnet (not shown) is disposed on one of the lower housing 2 and the upper housing 3 and a magnetic sensor (not shown) at a position where the magnetic force of the magnet can be detected when in the tablet state on the other. Place. And the magnetic processing part (not shown) provided instead of the acceleration processing part 11 may detect a tablet state based on the detection result of a magnetic sensor.
　キーボードコントローラー１２は、キーボード部５０のキーボード５（ＫＢ）およびタッチパッド６（ＭＳ）と接続されるとともに、ＬＰＣ（Low　Pin　Count）バスを介してチップセット３０と接続される。Ｉ２Ｃコントローラー１３は、タッチパネル部２０とＩ２Ｃ（アイ・スクエアド・シー）バスを介して通信を行うコントローラーである。 The keyboard controller 12 is connected to the keyboard 5 (KB) and the touch pad 6 (MS) of the keyboard unit 50, and connected to the chipset 30 via a low pin count (LPC) bus. The I2C controller 13 is a controller that communicates with the touch panel unit 20 via an I 2 C (eye squared sea) bus.
　キーボードコントローラー１２は、加速度処理部１１の検出結果をもとに、タブレット状態でない場合（例えば通常のノートＰＣ状態など）、キーボード５およびタッチパッド６に対する入力操作に応じた操作信号をＬＰＣバスを介してチップセット３０に出力する。 When the keyboard controller 12 is not in the tablet state (for example, in a normal notebook PC state) based on the detection result of the acceleration processing unit 11, an operation signal corresponding to an input operation on the keyboard 5 and the touch pad 6 is made via the LPC bus. Output to the chipset 30.
　なお、情報処理装置１がタブレット状態である場合、キーボード５およびタッチパッド６は使用しない。よって、タブレット状態である場合、キーボードコントローラー１２は、キーボード５やタッチパッド６を操作してもＣＰＵ３５に割り込みを入れないように、ＬＰＣバスを介した操作信号の出力を抑制する。 When the information processing apparatus 1 is in the tablet state, the keyboard 5 and the touch pad 6 are not used. Therefore, in the tablet state, the keyboard controller 12 suppresses the output of the operation signal via the LPC bus so as not to interrupt the CPU 35 even if the keyboard 5 or the touch pad 6 is operated.
　また、キーボードコントローラー１２は、タブレット状態であることを検出しているときに、キーボード５およびタッチパッド６に対する入力操作を検出すると、タッチパネル８の外周部分における入力操作を非検出するための通知をＩ２Ｃコントローラー１３を介してタッチパネル部２０に行う。 In addition, when the keyboard controller 12 detects that it is in the tablet state, when it detects an input operation to the keyboard 5 and the touch pad 6, it notifies the notification for not detecting the input operation on the outer peripheral portion of the touch panel 8 as I2C. The touch panel unit 20 is operated via the controller 13.
　図４は、組み込みコントローラー１０にかかる処理例を示すフローチャートである。図４に示すように、キーボードコントローラー１２は、加速度処理部１１の検出結果をもとに、情報処理装置１がタブレット状態であるか否かを判定する（Ｓ１）。タブレット状態でない場合（Ｓ１：ＮＯ）、キーボードコントローラー１２は、処理をリターンする。 FIG. 4 is a flow chart showing an example of processing performed by the embedded controller 10. As shown in FIG. 4, the keyboard controller 12 determines whether the information processing apparatus 1 is in the tablet state based on the detection result of the acceleration processing unit 11 (S1). If it is not in the tablet state (S1: NO), the keyboard controller 12 returns the process.
　タブレット状態である場合（Ｓ１：ＹＥＳ）、キーボードコントローラー１２は、キーボード５（ＫＢ）およびタッチパッド６（ＭＳ）への押下などによる入力の有無を判定する（Ｓ２）。 When it is in the tablet state (S1: YES), the keyboard controller 12 determines the presence or absence of input by pressing the keyboard 5 (KB) and the touch pad 6 (MS) (S2).
　入力がある場合（Ｓ２：ＹＥＳ）、キーボードコントローラー１２は、キーボード５またはタッチパッド６における入力が、予め設定されたいずれかの入力範囲で行われたか否かを判定する（Ｓ３）。 When there is an input (S2: YES), the keyboard controller 12 determines whether the input on the keyboard 5 or the touch pad 6 has been performed in any of the preset input ranges (S3).
　図５は、入力範囲を説明する説明図である。図５に示すように、キーボードコントローラー１２には、タブレット状態として使用される際の、筐体（下部筐体２）裏面の外周部分、すなわちキーボード５およびタッチパッド６における外周部分に対応する入力範囲Ｒ１１～Ｒ１４が予め設定されている。具体的には、筐体（下部筐体２）の端部から数センチメートル内にあるキーボード５およびタッチパッド６における操作領域が入力範囲Ｒ１１～Ｒ１４として設定されている。 FIG. 5 is an explanatory view for explaining an input range. As shown in FIG. 5, in the keyboard controller 12, an input range corresponding to the outer peripheral portion of the back surface of the housing (lower housing 2), ie, the outer peripheral portions of the keyboard 5 and the touch pad 6 when used as a tablet state R11 to R14 are preset. Specifically, operation areas in the keyboard 5 and the touch pad 6 which are within several centimeters from the end of the housing (lower housing 2) are set as the input ranges R11 to R14.
　タブレット状態とした情報処理装置１を利用者が把持して使用する場合は、裏面を支える指などでキーボード５またはタッチパッド６における入力範囲Ｒ１１～Ｒ１４が押下され、入力範囲Ｒ１１～Ｒ１４に配置されたキーに対する入力操作として検出されることがある。 When the user holds and uses the information processing apparatus 1 in the tablet state, the input range R11 to R14 of the keyboard 5 or the touch pad 6 is pressed down with a finger or the like supporting the back surface and arranged in the input range R11 to R14. It may be detected as an input operation on another key.
　したがって、キーボードコントローラー１２は、タブレット状態である場合に、キーボード５またはタッチパッド６における入力が入力範囲Ｒ１１～Ｒ１４のいずれかのキーに対する入力で行われたか否かを判定することで、タブレット状態とした情報処理装置１を利用者が把持して使用しているか否かを判別する。 Therefore, when the keyboard controller 12 is in the tablet state, the keyboard controller 12 determines whether or not the input on the keyboard 5 or the touch pad 6 is performed by the input to any key in the input range R11 to R14. It is determined whether the user holds and uses the information processing apparatus 1 as described above.
　キーボード５またはタッチパッド６における入力が入力範囲Ｒ１１～Ｒ１４のいずれかのキーに対する入力が行われていない場合（Ｓ３：ＮＯ）、情報処理装置１を利用者が把持しておらず、テーブルなどに置いて使用しているものとし、キーボードコントローラー１２は、Ｓ６へ処理を進める。 When the input on the keyboard 5 or the touch pad 6 is not performed with respect to any key in the input range R11 to R14 (S3: NO), the user does not grip the information processing apparatus 1, and a table etc. It is assumed that the keyboard controller 12 has placed and used it, and the process proceeds to S6.
　キーボード５またはタッチパッド６における入力が入力範囲Ｒ１１～Ｒ１４のいずれかのキーに対する入力が行われている場合（Ｓ３：ＹＥＳ）、キーボードコントローラー１２は、タッチパネル８の外周部分における入力操作を非検出とするタッチ不反応要求をＩ２Ｃコントローラー１３を介してタッチパネル部２０へ送出する（Ｓ４）。 When the input on the keyboard 5 or the touch pad 6 is performed for any key in the input range R11 to R14 (S3: YES), the keyboard controller 12 determines that the input operation on the outer peripheral portion of the touch panel 8 is not detected. To the touch panel unit 20 via the I2C controller 13 (S4).
　次いで、キーボードコントローラー１２は、キーボード５またはタッチパッド６における入力位置、すなわち入力が行われた入力範囲Ｒ１１～Ｒ１４に対応するタッチ不反応パターン番号をＩ２Ｃコントローラー１３を介してタッチパネル部２０へ送出し（Ｓ５）、処理をリターンする。このタッチ不反応パターン番号は、タッチパネル８の外周部分においてタッチによる入力操作を不反応（非検出）とする範囲（タッチ不反応範囲）を示す値である。 Next, the keyboard controller 12 sends the touch unresponsive pattern number corresponding to the input position on the keyboard 5 or the touch pad 6, ie, the input range R11 to R14 in which the input was performed, to the touch panel unit 20 via the I2C controller 13 ( S5), return the process. The touch unresponsiveness pattern number is a value indicating a range (touch unresponsiveness range) in which the input operation by the touch in the outer peripheral portion of the touch panel 8 is unresponsive (not detected).
　図６は、タッチ不反応範囲を説明する説明図である。図６に示すように、タッチパネル８の外周部分には、端から数センチメートルの範囲で、タッチ不反応範囲Ｒ２１～Ｒ２４が予め設定されている。具体的には、タッチパネル８の上辺から数センチメートルの範囲では、タッチ不反応範囲Ｒ２１が設定されている。また、下辺から数センチメートルの範囲では、タッチ不反応範囲Ｒ２３が設定されている。また、タッチパネル８の左右の両辺には、タッチ不反応範囲Ｒ２２、Ｒ２４が設定されている。 FIG. 6 is an explanatory view for explaining a touch non-responsive range. As shown in FIG. 6, in the outer peripheral portion of the touch panel 8, touch insensitive ranges R21 to R24 are set in advance within a range of several centimeters from the end. Specifically, in the range of several centimeters from the upper side of the touch panel 8, a touch non-responsiveness range R21 is set. Further, in the range of several centimeters from the lower side, the touch unresponsiveness range R23 is set. In addition, touch insensitive ranges R22 and R24 are set on both left and right sides of the touch panel 8.
　Ｓ５において、キーボードコントローラー１２は、入力が行われた入力範囲Ｒ１１～Ｒ１４（図５参照）について、入力範囲Ｒ１１～Ｒ１４のそれぞれに対応して予め設定されたタッチ不反応範囲Ｒ２１～Ｒ２４を示すタッチ不反応パターン番号をタッチパネル部２０へ送出する。 In S5, the keyboard controller 12 displays the touch insensitive ranges R21 to R24 set in advance corresponding to the respective input ranges R11 to R14 in the input ranges R11 to R14 (see FIG. 5) in which the input is performed. The unresponsive pattern number is sent to the touch panel unit 20.
　例えば、キーボード５の入力範囲Ｒ１１のキーに対する入力が行われた場合、利用者が上辺部分を把持して情報処理装置１を利用しているものと推定される。このような場合、上辺部分に近いタッチ不反応範囲Ｒ２１において把持した指の誤検知が行われる可能性が高くなる。 For example, when an input to the key of the input range R11 of the keyboard 5 is performed, it is estimated that the user holds the upper side portion and uses the information processing apparatus 1. In such a case, the possibility of erroneous detection of the finger held in the touch unresponsiveness range R21 close to the upper side portion becomes high.
　したがって、キーボードコントローラー１２は、入力範囲Ｒ１１のキーに対する入力が行われた場合には、入力範囲Ｒ１１に対応するタッチ不反応範囲Ｒ２１を示すタッチ不反応パターン番号をタッチパネル部２０へ送出する。このように、入力範囲Ｒ１１～Ｒ１４については、筐体の表裏で対応するタッチ不反応範囲Ｒ２１～Ｒ２４を示すタッチ不反応パターン番号が予め設定されている。そして、キーボードコントローラー１２は、入力が行われた入力範囲Ｒ１１～Ｒ１４のキーに対して、筐体の表裏で対応するタッチパネル８の外周部分をタッチ不反応範囲とするように、タッチ不反応パターン番号をタッチパネル部２０へ送出する。 Therefore, the keyboard controller 12 sends the touch unresponsiveness pattern number indicating the touch unresponsiveness range R21 corresponding to the input range R11 to the touch panel unit 20 when the input to the key of the input range R11 is performed. As described above, for the input ranges R11 to R14, touch non-responsive pattern numbers indicating the corresponding touch non-responsive ranges R21 to R24 on the front and back of the casing are set in advance. Then, the keyboard controller 12 sets the touch unresponsiveness pattern number so that the outer peripheral portion of the touch panel 8 corresponding to the front and back of the casing corresponds to the touch unresponsiveness range with respect to the keys of the input range R11 to R14 where the input is performed Is sent to the touch panel unit 20.
　なお、キーボード５（ＫＢ）およびタッチパッド６（ＭＳ）への押下などによる入力がない場合（Ｓ２：ＮＯ）、キーボードコントローラー１２は、タッチ不反応の取り下げ要求をＩ２Ｃコントローラー１３を介してタッチパネル部２０へ送出し（Ｓ６）、処理をリターンする。 When there is no input by pressing the keyboard 5 (KB) and the touch pad 6 (MS) (S2: NO), the keyboard controller 12 requests the withdrawal of the touch unresponsiveness via the touch panel unit 20 via the I2C controller 13. To the terminal (S6), and the process returns.
　図３に戻り、タッチパネル部２０は、上部筐体３に設けられた入力デバイスであり、タッチパネル８、コントローラー２１および記憶部２２を有する。 Returning to FIG. 3, the touch panel unit 20 is an input device provided in the upper housing 3 and includes the touch panel 8, the controller 21, and the storage unit 22.
　コントローラー２１は、タッチパネル８より押下操作された入力位置（座標）の検出、検出された入力位置を示す座標データのチップセット３０への送出など、タッチパネル部２０にかかる処理を実行するコントローラーである。 The controller 21 is a controller that executes processing related to the touch panel unit 20, such as detection of an input position (coordinates) pressed by the touch panel 8 and sending of coordinate data indicating the detected input position to the chipset 30.
　コントローラー２１は、Ｉ２Ｃバスを介し、組み込みコントローラー１０と接続するインターフェースと、チップセット３０と接続するインターフェースとを有する。コントローラー２１は、組み込みコントローラー１０と接続するインターフェースからは、組み込みコントローラー１０から送出された情報（タッチ不反応要求、タッチ不反応パターン番号、タッチ不反応取り下げ要求など）を受信する。そして、コントローラー２１は、組み込みコントローラー１０から送出された情報をもとに、タッチパネル８より検出された入力位置を示す座標データを、チップセット３０と接続するインターフェースからチップセット３０へ送出する。 The controller 21 has an interface connected to the embedded controller 10 and an interface connected to the chipset 30 via the I 2 C bus. The controller 21 receives information (a touch unresponsiveness request, a touch unresponsiveness pattern number, a touch unresponsiveness cancellation request, etc.) sent from the embedded controller 10 from an interface connected to the embedded controller 10. Then, based on the information sent from the built-in controller 10, the controller 21 sends coordinate data indicating the input position detected by the touch panel 8 to the chipset 30 from the interface connected to the chipset 30.
　例えば、コントローラー２１は、タッチ不反応要求およびタッチ不反応パターン番号が組み込みコントローラー１０より送出されている（タブレット状態を検出しているときに、キーボード部５０に対する入力操作を検出している）場合、タッチパネル８の外周部分（タッチ不反応パターン番号に対応する範囲）における入力操作を非検出とする。すなわち、タッチ不反応パターン番号に対応するタッチ不反応範囲Ｒ２１～Ｒ２４において行われた入力操作については、コントローラー２１は、座標データの送出を抑止する。このように、コントローラー２１は、入力検出部の一例である。 For example, when the touch unresponsiveness request and the touch unresponsiveness pattern number are sent out from the built-in controller 10 (when detecting an input operation to the keyboard unit 50 when detecting a tablet state), the controller 21: The input operation on the outer peripheral portion (the range corresponding to the touch unresponsive pattern number) of the touch panel 8 is not detected. That is, for the input operation performed in the touch unresponsiveness range R21 to R24 corresponding to the touch unresponsiveness pattern number, the controller 21 suppresses the sending of coordinate data. Thus, the controller 21 is an example of the input detection unit.
　記憶部２２は、タッチパネル８より検出した入力位置（座標）を示す座標データや、組み込みコントローラー１０より送出された情報などの各種情報を一時記憶するメモリである。 The storage unit 22 is a memory for temporarily storing various information such as coordinate data indicating an input position (coordinates) detected by the touch panel 8 and information sent from the built-in controller 10.
　図７は、タッチパネル８にかかる処理例を示すフローチャートである。図７に示すように、処理が開始されると、コントローラー２１は、組み込みコントローラー１０からの、タッチ不反応要求の受信の有無を判定する（Ｓ１０）。ここで、タッチ不反応要求の受信がない場合（Ｓ１０：ＮＯ）、コントローラー２１は、Ｓ１３へ処理を進める。 FIG. 7 is a flowchart showing an example of processing performed by the touch panel 8. As shown in FIG. 7, when the process is started, the controller 21 determines whether or not the touch unresponsiveness request has been received from the embedded controller 10 (S10). Here, when there is no reception of the touch unresponsiveness request (S10: NO), the controller 21 advances the process to S13.
　タッチ不反応要求の受信がある場合（Ｓ１０：ＹＥＳ）、コントローラー２１は、タッチ不反応パターン番号を組み込みコントローラー１０より受信し（Ｓ１１）、受信したタッチ不反応パターン番号を記憶部２２に記憶する（Ｓ１２）。 When the touch unresponsiveness request is received (S10: YES), the controller 21 receives the touch unresponsiveness pattern number from the controller 10 (S11), and stores the received touch unresponsiveness pattern number in the storage unit 22 (S10). S12).
　Ｓ１３において、コントローラー２１は、組み込みコントローラー１０からの、タッチ不反応取り下げ要求の受信の有無を判定する。ここで、タッチ不反応取り下げ要求の受信がない場合（Ｓ１３：ＮＯ）、コントローラー２１は、Ｓ１５へ処理を進める。 In S13, the controller 21 determines whether or not the touch unresponsiveness cancellation request has been received from the embedded controller 10. Here, when there is no reception of the touch unresponsiveness cancellation request (S13: NO), the controller 21 advances the process to S15.
　タッチ不反応取り下げ要求の受信がある場合（Ｓ１３：ＹＥＳ）、コントローラー２１は、記憶部２２に記憶したタッチ不反応パターン番号の記憶削除を行う（Ｓ１４）。 When the touch unresponsiveness cancellation request has been received (S13: YES), the controller 21 performs storage deletion of the touch unresponsiveness pattern number stored in the storage unit 22 (S14).
　Ｓ１５において、コントローラー２１は、タッチパネル８におけるタッチ入力の有無を判定する（Ｓ１５）。タッチ入力がない場合（Ｓ１５：ＮＯ）、コントローラー２１は、処理をリターンする。 In S15, the controller 21 determines the presence or absence of touch input on the touch panel 8 (S15). When there is no touch input (S15: NO), the controller 21 returns the process.
　タッチ入力がある場合（Ｓ１５：ＹＥＳ）、コントローラー２１は、タッチ入力の座標が記憶部２２に記憶したタッチ不反応パターン番号に対応するタッチ不反応範囲Ｒ２１～Ｒ２４内であるか否かを判定する（Ｓ１６）。 When there is touch input (S15: YES), the controller 21 determines whether or not the coordinates of the touch input fall within the touch non-responsiveness range R21 to R24 corresponding to the touch non-responsiveness pattern number stored in the storage unit 22. (S16).
　タッチ入力の座標がタッチ不反応パターン番号に対応するタッチ不反応範囲Ｒ２１～Ｒ２４内である場合（Ｓ１６：ＹＥＳ）、コントローラー２１は、座標データの送出を行わずに処理をリターンする。これにより、情報処理装置１は、利用者が把持した際にタッチパネル８まで指が触れてしまうことによる誤検知を抑止できる。 When the coordinates of touch input are within the touch non-responsiveness range R21 to R24 corresponding to the touch non-responsiveness pattern number (S16: YES), the controller 21 returns the process without sending out the coordinate data. Thereby, the information processing apparatus 1 can suppress false detection due to the finger touching the touch panel 8 when the user holds the information.
　タッチ入力の座標がタッチ不反応パターン番号に対応するタッチ不反応範囲Ｒ２１～Ｒ２４内でない場合（Ｓ１６：ＮＯ）、コントローラー２１は、タッチ入力のあった座標を示す座標データをチップセット３０に送出し（Ｓ１７）、処理をリターンする。 If the coordinates of the touch input are not within the touch non-responsiveness range R21 to R24 corresponding to the touch non-responsive pattern number (S16: NO), the controller 21 sends coordinate data indicating the coordinates at which the touch input occurred to the chipset 30. (S17), the process returns.
　図３に戻り、チップセット３０は、Ｉ２Ｃコントローラー３１、ＬＰＣコントローラー３２、ＡＨＣＩコントローラー３３、グラフィックコントローラー３４、ＣＰＵ３５およびメモリ３６を有する。 Returning to FIG. 3, the chipset 30 includes an I2C controller 31, an LPC controller 32, an AHCI controller 33, a graphic controller 34, a CPU 35, and a memory 36.
　Ｉ２Ｃコントローラー３１は、タッチパネル部２０とＩ２Ｃ（アイ・スクエアド・シー）バスを介して通信を行うコントローラーである。Ｉ２Ｃコントローラー３１は、タッチパネル部２０よりＩ２Ｃ（アイ・スクエアド・シー）バスを介してタッチ入力のあった座標を示す座標データを受信する。これにより、チップセット３０では、タッチパネル部２０において利用者が行ったタッチ操作を受け付ける。 I2C controller 31 is a controller that performs communication via the touch panel unit 20 and the I 2 C (I Square de Sea) bus. The I2C controller 31 receives coordinate data indicating coordinates at which a touch input has been made from the touch panel unit 20 via an I 2 C (eye squared sea) bus. Thus, the chipset 30 receives the touch operation performed by the user on the touch panel unit 20.
　ＬＰＣコントローラー３２は、キーボードコントローラー１２とＬＰＣバスを介して通信を行うコントローラーである。ＬＰＣコントローラー３２は、キーボードコントローラー１２よりＬＰＣバスを介してキーボード５およびタッチパッド６に対する入力操作に応じた操作信号を受信する。これにより、チップセット３０では、キーボード５において利用者が行った入力操作を受け付ける。 The LPC controller 32 is a controller that communicates with the keyboard controller 12 via the LPC bus. The LPC controller 32 receives an operation signal corresponding to an input operation on the keyboard 5 and the touch pad 6 from the keyboard controller 12 via the LPC bus. Thus, the chipset 30 accepts an input operation performed by the user on the keyboard 5.
　ＡＨＣＩコントローラー３３は、ＡＨＣＩ（Advanced　Host　Controller　Interface）にかかる処理を行うコントローラーである。ＡＨＣＩコントローラー３３は、ＡＨＣＩを介してストレージ４０と接続し、ストレージ４０におけるデータの読み書きなどを行う。 The AHCI controller 33 is a controller that performs processing related to AHCI (Advanced Host Controller Interface). The AHCI controller 33 is connected to the storage 40 via the AHCI to read and write data in the storage 40.
　グラフィックコントローラー３４は、ＬＣＤパネル７と接続されており、ＬＣＤパネル７に表示する表示画面にかかる画像処理を実行するコントローラーである。 The graphic controller 34 is connected to the LCD panel 7 and is a controller that executes image processing on a display screen displayed on the LCD panel 7.
　ＣＰＵ３５は、メモリ３６に記憶されたプログラム３６ａを順次実行することで、情報処理装置１の全体動作を統括制御する。メモリ３６は、ＣＰＵ３５が実行するプログラム３６ａなどを記憶する。なお、本実施形態のキーボードコントローラー１２およびコントローラー２１にかかる処理は、ＣＰＵ３５がプログラム３６ａを実行することで、実現してもよい。 The CPU 35 executes the programs 36 a stored in the memory 36 sequentially to control the overall operation of the information processing apparatus 1. The memory 36 stores a program 36 a and the like that the CPU 35 executes. The processing of the keyboard controller 12 and the controller 21 according to the present embodiment may be realized by the CPU 35 executing the program 36 a.
　ストレージ４０は、例えばＳＳＤ（Solid　State　Drive）などであり、各種データ、アプリケーションプログラムなどを格納する。ストレージ４０では、ＡＨＣＩコントローラー３３を介してデータの読み書きが行われる。 The storage 40 is, for example, a solid state drive (SSD), and stores various data, application programs, and the like. In the storage 40, reading and writing of data are performed via the AHCI controller 33.
　キーボード部５０は、キーボード５（ＫＢ）およびタッチパッド６（ＭＳ）などの、下部筐体２に設けられた入力デバイスである。 The keyboard unit 50 is an input device provided in the lower housing 2 such as the keyboard 5 (KB) and the touch pad 6 (MS).
　以上のように、情報処理装置１は、タッチパネル８を備える上部筐体３の裏面と、キーボード部５０を備える下部筐体２の裏面とが向かい合う位置に位置するか（タブレット状態であるか）を判断する加速度処理部１１を有する。また、情報処理装置１は、タブレット状態と判断すると、キーボード部５０に対する入力が行われている間、タッチパネル８の外周部分に対する入力は非検出とするコントローラー２１を有する。したがって、情報処理装置１は、新たに接触センサーを配置するなどの構成を複雑にすることなく簡易に、利用者が情報処理装置１を把持した際などに生じるタッチパネル８における誤検知を抑止することができる。 As described above, whether the information processing apparatus 1 is positioned at a position where the back surface of the upper housing 3 including the touch panel 8 and the back surface of the lower housing 2 including the keyboard unit 50 face each other (in a tablet state) It has the acceleration processing part 11 to judge. Further, the information processing apparatus 1 has a controller 21 that does not detect an input to the outer peripheral portion of the touch panel 8 while an input to the keyboard unit 50 is performed when it is determined that the tablet state is set. Therefore, the information processing apparatus 1 suppresses erroneous detection in the touch panel 8 which occurs when the user grips the information processing apparatus 1 or the like, without complicating the configuration of arranging a new contact sensor or the like. Can.
　また、情報処理装置１では、裏面のキーボード５およびタッチパッド６の外周部分（入力範囲Ｒ１１～Ｒ１４）における入力操作を検出すると、表面のタッチパネル８の外周部分（タッチ不反応範囲Ｒ２１～Ｒ２４）における入力操作を非検出とする。このように、キーボード５およびタッチパッド６の外周部分（入力範囲Ｒ１１～Ｒ１４）における入力操作が行われる場合には、タブレット状態とした情報処理装置１を利用者が把持して使用しているものと推定される。このような場合、把持した指により誤操作が行われやすい、タッチパネル８の外周部分（タッチ不反応範囲Ｒ２１～Ｒ２４）における入力操作を非検出とすることで、誤操作を抑制することができる。 Further, in the information processing apparatus 1, when an input operation in the outer peripheral portion (input range R11 to R14) of the keyboard 5 and the touch pad 6 on the back surface is detected, the outer peripheral portion (touch insensitive range R21 to R24) of the touch panel 8 on the front surface is detected. The input operation is not detected. As described above, when the input operation is performed on the outer peripheral portion (input range R11 to R14) of the keyboard 5 and the touch pad 6, the user holds and uses the information processing apparatus 1 in the tablet state. It is estimated to be. In such a case, the erroneous operation can be suppressed by not detecting the input operation in the outer peripheral portion (touch insensitive range R21 to R24) of the touch panel 8 where the erroneous operation is easily performed by the griped finger.
　また、情報処理装置１は、裏面におけるキーボード５およびタッチパッド６の外周部分に配置されたキー（入力範囲Ｒ１１～Ｒ１４のいずれか）に対する入力に基いて、表面のタッチパネル８の外周部分における入力操作を非検出とする位置（タッチ不反応範囲Ｒ２１～Ｒ２４のいずれか）を決定し、決定された位置を非検出とする。これにより、情報処理装置１は、キーボード５およびタッチパッド６の入力位置をもとに、利用者が把持した位置として表裏で対応するタッチパネル８の外周部分の位置の入力操作を非検出とすることができ、誤検知の抑止を精度よく行うことができる。 In addition, the information processing apparatus 1 performs an input operation on the outer peripheral portion of the touch panel 8 on the surface based on an input to a key (one of the input ranges R11 to R14) disposed on the outer peripheral portion of the keyboard 5 and the touch pad 6 on the back surface. A position where any one of the touch insensitive areas R21 to R24 is to be detected is determined, and the determined position is determined as not detected. Thereby, based on the input positions of the keyboard 5 and the touch pad 6, the information processing apparatus 1 does not detect the input operation of the position of the outer peripheral portion of the touch panel 8 corresponding to the front and back as the position held by the user. And the false detection can be accurately suppressed.
（第２の実施形態）
　図８は、第２の実施形態にかかる情報処理装置の外観を説明する説明図である。図８に示すように、情報処理装置１ａは、キーボード５、タッチパッド６の代わりにＬＣＤパネル７ａと、ＬＣＤパネル７ａに重畳してタッチパネル８ａとを配置した構成である。すなわち、情報処理装置１ａは、タブレット状態において表裏の両面がタッチパネル８またはタッチパネル８ａとなる。 Second Embodiment
FIG. 8 is an explanatory view for explaining the appearance of the information processing apparatus according to the second embodiment. As shown in FIG. 8, the information processing apparatus 1 a has a configuration in which an LCD panel 7 a and a touch panel 8 a are superimposed on the LCD panel 7 a instead of the keyboard 5 and the touch pad 6. That is, in the information processing apparatus 1a, both sides of the front and back become the touch panel 8 or the touch panel 8a in the tablet state.
　図９は、第２の実施形態にかかる情報処理装置１ａの構成例を示すブロック図である。図９に示すように、情報処理装置１ａは、上部筐体３側に設けられる第１タッチパネル部２０ａの他に、キーボード部５０に代わって下部筐体２側に設けられる第２タッチパネル部２０ｂを有する点が情報処理装置１とは異なる。また、加速度センサー６１ａは、第１タッチパネル部２０ａにかかる加速度を計測するセンサーである。また、加速度センサー６２ａは、第２タッチパネル部２０ｂにかかる加速度を計測するセンサーである。 FIG. 9 is a block diagram showing a configuration example of the information processing apparatus 1a according to the second embodiment. As shown in FIG. 9, in addition to the first touch panel unit 20 a provided on the upper housing 3 side, the information processing apparatus 1 a includes a second touch panel unit 20 b provided on the lower housing 2 side instead of the keyboard unit 50. The point which it has differs from the information processing apparatus 1. The acceleration sensor 61a is a sensor that measures the acceleration applied to the first touch panel unit 20a. The acceleration sensor 62a is a sensor that measures the acceleration applied to the second touch panel unit 20b.
　第１タッチパネル部２０ａおよび第２タッチパネル部２０ｂともに、組み込みコントローラー１０、チップセット３０とはＩ２Ｃ（アイ・スクエアド・シー）バスを介して接続される。また、第２タッチパネル部２０ｂも第１タッチパネル部２０ａと同様に、タッチパネル８ａ、コントローラー２１ａおよび記憶部２２ｂを有する。 Both the first touch panel unit 20a and the second touch panel unit 20b are connected to the built-in controller 10 and the chipset 30 via an I 2 C (eye squared sea) bus. Moreover, the 2nd touch panel part 20b also has the touch panel 8a, the controller 21a, and the memory | storage part 22b similarly to the 1st touch panel part 20a.
　加速度処理部１１は、加速度センサー６１ａ、加速度センサー６２ａによる検知結果をもとに、情報処理装置１ａがタブレット状態であるか否かを検出する。また、加速度処理部１１は、加速度センサー６１ａ、加速度センサー６２ａによる重力加速度の検知結果をもとに、表面および裏面を特定する。組み込みコントローラー１０は、第１タッチパネル部２０ａ、第２タッチパネル部２０ｂにおいて、表面と特定した側（例えば第１タッチパネル部２０ａ）から得られた入力操作の内容をチップセット３０へ送出する。 The acceleration processing unit 11 detects whether or not the information processing apparatus 1a is in the tablet state based on the detection results of the acceleration sensor 61a and the acceleration sensor 62a. In addition, the acceleration processing unit 11 specifies the front and back surfaces based on the detection results of the gravitational acceleration by the acceleration sensor 61a and the acceleration sensor 62a. The embedded controller 10 sends the content of the input operation obtained from the side specified as the surface (for example, the first touch panel unit 20 a) in the first touch panel unit 20 a and the second touch panel unit 20 b to the chipset 30.
　また、組み込みコントローラー１０は、タブレット状態であることを検出しているときに、裏面と特定した側（例えば第２タッチパネル部２０ｂ）に対する入力操作を検出すると、表面のタッチパネル８の外周部分における入力操作を非検出するための通知をＩ２Ｃコントローラー１３を介して第１タッチパネル部２０ａに行う。 When the built-in controller 10 detects that it is in the tablet state, it detects an input operation on the side identified as the back surface (for example, the second touch panel unit 20b), and performs an input operation on the outer peripheral portion of the touch panel 8 on the front surface. Is notified to the first touch panel unit 20a via the I2C controller 13 for non-detection.
　図１０は、組み込みコントローラーにかかる処理例を示すフローチャートである。図１０に示すように、組み込みコントローラー１０は、加速度処理部１１の検出結果をもとに、情報処理装置１ａがタブレット状態であるか否かを判定する（Ｓ２０）。タブレット状態でない場合（Ｓ２０：ＮＯ）、組み込みコントローラー１０は、前回がタブレット状態であったか否かを判定する（Ｓ２１）。 FIG. 10 is a flow chart showing an example of processing performed by the embedded controller. As shown in FIG. 10, based on the detection result of the acceleration processing unit 11, the embedded controller 10 determines whether the information processing apparatus 1a is in the tablet state (S20). If it is not in the tablet state (S20: NO), the embedded controller 10 determines whether or not the previous state was in the tablet state (S21).
　前回がタブレット状態であった場合（Ｓ２１：ＹＥＳ）、組み込みコントローラー１０は、タッチパネル８、８ａの入力操作を示すタッチ情報の送出のキャンセル要求を第１タッチパネル部２０ａ、第２タッチパネル部２０ｂに送出する（Ｓ２２）。前回がタブレット状態でない場合（Ｓ２１：ＮＯ）、組み込みコントローラー１０は処理をリターンする。 If the previous state is the tablet state (S21: YES), the embedded controller 10 sends a cancellation request for sending out touch information indicating the input operation of the touch panels 8 and 8a to the first touch panel unit 20a and the second touch panel unit 20b. (S22). If the previous state is not in the tablet state (S21: NO), the embedded controller 10 returns the process.
　Ｓ２０において、タブレット状態である場合（Ｓ２０：ＹＥＳ）、組み込みコントローラー１０は、前回がタブレット状態であったか否かを判定する（Ｓ２３）。前回がタブレット状態でない場合（Ｓ２３：ＮＯ）、組み込みコントローラー１０は、タッチ情報送出の要求を第１タッチパネル部２０ａ、第２タッチパネル部２０ｂに送出する（Ｓ２４）。 In S20, when it is in the tablet state (S20: YES), the embedded controller 10 determines whether the previous state was the tablet state (S23). If the previous time is not in the tablet state (S23: NO), the embedded controller 10 sends a request for touch information transmission to the first touch panel unit 20a and the second touch panel unit 20b (S24).
　前回がタブレット状態であった場合（Ｓ２３：ＹＥＳ）、組み込みコントローラー１０は、裏面と特定した側（例えば第２タッチパネル部２０ｂ）の所定のエリア（入力範囲）がタッチされているか否かを判定する（Ｓ２５）。 If the previous state is the tablet state (S23: YES), the embedded controller 10 determines whether or not a predetermined area (input range) on the side (for example, the second touch panel unit 20b) specified as the back side is touched. (S25).
　図１１は、入力範囲を説明する説明図である。図１１に示すように、組み込みコントローラー１０には、裏面とするタッチパネル８ａの外周部分に対して入力範囲Ｒ３１～Ｒ３４が設定されている。具体的には、筐体（下部筐体２）の端部から数センチメートル内にあるタッチパネル８ａにおける操作領域が入力範囲Ｒ３１～Ｒ３４として設定されている。なお、本実施形態の説明ではタッチパネル８ａが裏側にある場合を例示しているが、タッチパネル８が裏側にある場合も同様な入力範囲が設定される。 FIG. 11 is an explanatory view for explaining an input range. As shown in FIG. 11, in the built-in controller 10, input ranges R31 to R34 are set with respect to the outer peripheral portion of the touch panel 8a which is the back surface. Specifically, the operation areas in the touch panel 8a within several centimeters from the end of the housing (lower housing 2) are set as the input ranges R31 to R34. In addition, although the case where the touch panel 8a is on the back side is illustrated in the description of the present embodiment, the same input range is set even when the touch panel 8 is on the back side.
　裏面の所定のエリアがタッチされている場合（Ｓ２５：ＹＥＳ）、組み込みコントローラー１０は、表面と特定した側（例えば第１タッチパネル部２０ａ）に対し、タッチパネル８の外周部分における入力操作を非検出とするタッチ不反応要求を送出する（Ｓ２６）。 When the predetermined area on the back side is touched (S25: YES), the built-in controller 10 does not detect the input operation on the outer peripheral portion of the touch panel 8 with respect to the side specified as the front side (for example, the first touch panel portion 20a). Send out a touch unresponsiveness request (S26).
　次いで、組み込みコントローラー１０は、裏面における入力位置、すなわち入力が行われた入力範囲Ｒ３１～Ｒ３４に対応するタッチ不反応パターン番号を表面と特定した側（例えば第１タッチパネル部２０ａ）に送出し（Ｓ２７）、処理をリターンする。 Next, the built-in controller 10 sends the touch unresponsive pattern number corresponding to the input position on the back surface, that is, the input range R31 to R34 in which the input is performed to the side (for example, the first touch panel unit 20a) specified as the front surface ), Return the process.
　なお、裏面の所定のエリアがタッチされていない場合（Ｓ２５：ＮＯ）、組み込みコントローラー１０は、タッチ不反応の取り下げ要求を表面と特定した側（例えば第１タッチパネル部２０ａ）に送出し（Ｓ２８）、処理をリターンする。 In addition, when the predetermined area on the back side is not touched (S25: NO), the built-in controller 10 sends out the request for withdrawal of the touch unresponsiveness to the side (for example, the first touch panel unit 20a) specified as the surface (S28) , Return the process.
　以上のように、タブレット状態において表裏の両面がタッチパネル８またはタッチパネル８ａとなる場合も同様に、表面にあるタッチパネル（例えばタッチパネル８）における誤検知を抑止することができる。 As described above, also in the case where both surfaces of the front and back are the touch panel 8 or the touch panel 8a in the tablet state, false detection in the touch panel (for example, the touch panel 8) on the surface can be suppressed similarly.
　特に、コンバーチブル型のノートＰＣの場合、通常のノート型ＰＣのときに操作を行うキーボード部５０の他に、タブレット状態のときに操作を行うタッチパネル部２０を有し、少なくとも一方にタッチパネル８を有する構成である。そして、タブレット状態のときは、ＬＣＤパネル７に重畳されるタッチパネル部２０を表面とし、キーボード部５０を裏面として使用される。このタブレット状態のときに、裏面として使用されるキーボード部５０の入力操作から、タッチパネル８の外周部分における入力操作を非検出とすることで、新たに接触センサーを配置するなどの構成を複雑にすることなく、簡易にタッチパネル８における誤検知を抑止することができる。 In particular, in the case of a convertible notebook PC, in addition to the keyboard unit 50 operating in the case of a normal notebook PC, it has a touch panel unit 20 operating in the tablet state, and at least one side has the touch panel 8. It is a structure. When in the tablet state, the touch panel unit 20 superimposed on the LCD panel 7 is used as the front surface, and the keyboard unit 50 is used as the rear surface. In this tablet state, the input operation in the outer peripheral portion of the touch panel 8 is not detected from the input operation of the keyboard unit 50 used as the back surface, and the configuration such as arranging a new contact sensor is complicated. Therefore, false detection in the touch panel 8 can be easily suppressed.
