Abstract

A touch panel device (20) does not display operation keys (61) when a scroll operation is performed, and when the scroll operation is ended, the touch panel device displays the operation keys (61) again. Consequently, operability and visibility are improved during a time when the scroll operation is performed, and key input can be restarted quickly after the scroll operation. Furthermore, even in a communication terminal having limited screen size and display area, the screen size can be effectively used by having the operation keys (61) not displayed when the scroll operation is performed.

Description

タッチパネル装置Touch panel device
　本発明は、手指でスクロール操作が可能なユーザインタフェースを有する通信端末に用いて好適なタッチパネル装置に関する。 The present invention relates to a touch panel device suitable for use in a communication terminal having a user interface capable of scrolling with a finger.
　近年、タッチパネル装置を搭載した通信端末が増えてきており、その１つとして携帯電話とＰＤＡ（Personal Digital Assistant）を融合させたスマートフォンと呼ばれるものがある。タッチパネル装置を搭載した通信端末には、同一画面に操作部と表示部（文字列を表示する）を分離して表示するようにしたものがあるが、このように表示すると、操作部と表示部とが同一画面に表示されることから、入力された文字列が長くなると、入力済みの文字を確認しながら文字を入力し続けることが難しくなる。この問題に対し、特許文献１で開示された発明では、ユーザが接触した操作部の接触位置を表示部に半透明で重畳表示するようにして、操作部を視認することなく接触位置の確認を可能にしている。また、特許文献２で開示された発明では、スクロール操作時にメニューなどの補助情報を適切な場所に移動させることで、新たな表示画像が補助情報に隠れることがないようにしている。 In recent years, communication terminals equipped with a touch panel device are increasing, and one of them is a so-called smart phone in which a mobile phone and a PDA (Personal Digital Assistant) are integrated. Some communication terminals equipped with the touch panel device separate and display the operation unit and the display unit (displaying a character string) on the same screen, but when displayed in this way, the operation unit and the display unit Since the character is displayed on the same screen, when the input character string becomes long, it becomes difficult to continue inputting characters while confirming the characters already input. To address this problem, in the invention disclosed in Patent Document 1, the contact position of the operation unit touched by the user is displayed on the display unit in a semitransparent manner so that the contact position can be confirmed without visually recognizing the operation unit. It is possible. Further, in the invention disclosed in Patent Document 2, by moving the auxiliary information such as the menu to an appropriate place at the time of the scroll operation, the new display image is prevented from being hidden in the auxiliary information.

　しかしながら、特許文献１で開示された発明では、重畳表示のオン時は操作部が重畳表示されるので、表示部の視認性が悪く、また入力中と入力後の情報が確認し難い。また、重畳表示のオン／オフの切り替えにスイッチ操作が必要であるため、操作性、視認性が良くない。特許文献２で開示された発明では、メニューなどの補助情報をスクロールした際に適切な場所へ移動させることから新たに表示された情報が見易くなるものの、補助情報は常に画面に表示され続けるので、メール作成のように入力した文章を確認しながら文字を入力するときや、入力した文章を確認するために表示部をスクロールさせたときに目障りになり、画面サイズや表示エリアに制限がある通信端末には適さない。 However, in the invention disclosed in Patent Document 1, since the operation unit is superimposed and displayed when the superimposed display is on, the visibility of the display unit is poor, and it is difficult to confirm information during and after input. Moreover, since switch operation is required to switch on / off of the superimposed display, operability and visibility are not good. In the invention disclosed in Patent Document 2, when the auxiliary information such as the menu is scrolled, the newly displayed information can be easily viewed since it is moved to an appropriate place, but the auxiliary information is always displayed on the screen. A communication terminal that is bothersome when you enter text while checking text like mail creation, or when you scroll the display to check the text you input, and the screen size and display area are limited Not suitable for
　本発明は、係る事情に鑑みてなされたものであり、操作性、視認性の向上が図れるとともに、画面サイズや表示エリアに制限がある通信端末にも適用できるタッチパネル装置を提供することを目的とする。 The present invention has been made in view of such circumstances, and it is an object of the present invention to provide a touch panel device that can improve operability and visibility and can also be applied to communication terminals with limited screen size and display area. Do.
　本発明のタッチパネル装置は、表示部と、操作キー及び前記操作キーにより入力された文字列を前記表示部に表示させる表示制御部と、前記表示部上に積層的に設けられ、ユーザの手指がタッチした位置に対応する座標情報を出力するタッチパネル部と、前記タッチパネル部から出力された前記座標情報に基づく入力情報を出力する入力制御部と、前記入力制御部から出力された前記入力情報を受けて前記表示制御部に前記表示部の表示制御のための情報を送る制御部と、を備え、前記タッチパネル部に対する前記ユーザの手指によるタッチが前記表示部の表示をスクロールさせるためのスクロール操作であった場合、前記制御部から前記表示制御部に前記表示制御のための情報が送られ、前記表示制御部は、前記情報に基づいて前記表示部において前記操作キーを非表示とする。 The touch panel device according to the present invention includes a display unit, a display control unit that causes an operation key and a character string input by the operation key to be displayed on the display unit, and a display unit configured to be stacked on the display unit. A touch panel unit that outputs coordinate information corresponding to a touched position; an input control unit that outputs input information based on the coordinate information output from the touch panel unit; and the input information output from the input control unit A control unit to send information for display control of the display unit to the display control unit, and a touch operation by the user's finger on the touch panel unit is a scroll operation for scrolling the display of the display unit , The control unit sends information for the display control to the display control unit, and the display control unit performs the display based on the information. And hide the operation keys in.
　上記構成によれば、スクロール操作中は操作キーを非表示にするので、操作性、視認性の向上が図れる。また、操作キーを非表示とすることで、画面サイズや表示エリアに制限がある通信端末でも画面サイズを有効に使用することができる。なお、スクロール中に文字等の入力を行うことは現実的には不可能であるので、操作キーを非表示にしてもユーザの利便性に悪影響はない。 According to the above configuration, since the operation key is not displayed during the scroll operation, the operability and the visibility can be improved. Further, by hiding the operation key, the screen size can be effectively used even in a communication terminal having a screen size and a display area limited. Since it is practically impossible to input characters and the like during scrolling, hiding the operation key does not adversely affect the convenience of the user.
　上記構成において、前記スクロール操作の開始から所定時間内に前記タッチパネルに対する前記ユーザの手指によるタッチがなされなかった場合、前記制御部から前記表示制御部に前記表示制御のための情報が送られ、前記表示制御部は、前記情報に基づいて前記表示部において前記操作キーを再表示させる。 In the above configuration, when the touch panel does not touch the touch panel within a predetermined time from the start of the scroll operation, the control unit sends information for the display control to the display control unit. The display control unit causes the display unit to redisplay the operation key based on the information.
　上記構成によれば、スクロール操作が終わると、操作キーを再表示するので、スクロール操作後、即座にキー入力を再開することができる。 According to the above configuration, when the scroll operation is completed, the operation key is displayed again, so that the key input can be resumed immediately after the scroll operation.
　上記構成において、前記スクロール操作の方向が下方向であった場合、前記表示制御部はスクロール後に前記表示部の上端部付近に表示されていた文字列が維持されるように前記操作キーを再表示させ、前記スクロール操作の方向が上方向であった場合、前記表示制御部はスクロール後に前記表示部の下端部付近に表示されていた文字列が維持されるように前記操作キーを再表示させる。 In the above configuration, when the direction of the scroll operation is downward, the display control unit redisplays the operation key so that the character string displayed near the upper end of the display unit is maintained after the scroll. If the direction of the scroll operation is upward, the display control unit causes the operation key to be displayed again so that the character string displayed near the lower end of the display unit after scrolling is maintained.
　上記構成によれば、操作キーの再表示時に、それ以前のスクロール操作の方向が下方向であれば、文字列の上半分が残るように操作キーを再表示し、操作キーの再表示以前のスクロール操作の方向が上方向であれば、文字列の下半分が残るように操作キーを再表示するので、スクロール操作終了時にユーザが着目していた文字列の部分が操作キーに隠されてしまうことがない。 According to the above configuration, when the operation key is redisplayed, if the direction of the previous scroll operation is downward, the operation key is redisplayed so that the upper half of the character string remains, and before the operation key is redisplayed. If the direction of the scroll operation is upward, the operation key is redisplayed so that the lower half of the character string remains, so the portion of the character string that the user focused on at the end of the scroll operation is hidden in the operation key I have not.
　本発明によれば、操作性、視認性の向上が図れるとともに、画面サイズや表示エリアに制限がある通信端末にも適用できる。 ADVANTAGE OF THE INVENTION According to this invention, while being able to aim at the improvement of operativity and visibility, it is applicable also to the communication terminal which has a restriction | limiting in screen size and a display area.

　以下、本発明を実施するための好適な実施の形態について、図面を参照して詳細に説明する。 Hereinafter, preferred embodiments for carrying out the present invention will be described in detail with reference to the drawings.
　図１は、本発明の一実施の形態に係る通信端末の概略構成を示すブロック図である。同図において、本実施の形態の通信端末１は、通信制御部２と、タイマ部３と、音声制御部４と、記憶部５と、表示部６と、表示制御部７と、タッチパネル部８と、入力制御部９と、電源回路部１０と、制御部１１とを備える。表示部６、表示制御部７、タッチパネル部８、入力制御部９及び制御部１１は、タッチパネル装置２０を構成する。 FIG. 1 is a block diagram showing a schematic configuration of a communication terminal according to an embodiment of the present invention. In the figure, the communication terminal 1 of the present embodiment includes a communication control unit 2, a timer unit 3, a voice control unit 4, a storage unit 5, a display unit 6, a display control unit 7, and a touch panel unit 8. , An input control unit 9, a power supply circuit unit 10, and a control unit 11. The display unit 6, the display control unit 7, the touch panel unit 8, the input control unit 9 and the control unit 11 constitute a touch panel device 20.
　通信制御部２は、無線通信時の制御を行う。タイマ部３は、スクロール操作時の時間測定等に使用される。音声制御部４は、無線通信時の音声制御を行う。すなわち、音声制御部４は、受信した通信相手の音声をスピーカ（図示略）やレシーバ（図示略）から出力し、通信端末１のユーザの音声をマイク（図示略）より入力する。記憶部５は、スクロール操作時のスクロール方向（下方向か上方向）等を記憶する。 The communication control unit 2 performs control at the time of wireless communication. The timer unit 3 is used for time measurement or the like at the time of scroll operation. The voice control unit 4 performs voice control during wireless communication. That is, the voice control unit 4 outputs the received voice of the other party of communication from a speaker (not shown) or a receiver (not shown), and inputs the voice of the user of the communication terminal 1 from a microphone (not shown). The storage unit 5 stores the scroll direction (downward or upward) and the like at the time of the scroll operation.
　表示部６は、液晶あるいは有機ＥＬ（Organic Electro-Luminescence）を有し、操作キー６１の表示と、操作キー６１により入力された文字列６２の表示に用いられる。表示制御部７は、表示部６に操作キー６１を表示させるとともに、操作キー６１により入力された文字列６２を表示させる。操作キー６１と文字列６２は、表示部６の同一画面に表示される。タッチパネル部８は、表示部６の表示面上に積層的に設けられ、通信端末１のユーザの手指がタッチした位置に対応する座標情報を出力する。ここで、タッチパネルの方式としては、抵抗膜方式、表面弾性波方式、電磁誘導方式、静電容量方式等があり、スマートフォン等の通信端末では主に静電容量方式が採用されている。静電容量方式は手指と導電膜との間における静電容量の変化を捉えて位置を検出する方式である。入力制御部９は、タッチパネル部８から出力された座標情報に基づく入力情報を出力する。電源回路部１０は、装置本体の各部に電源を供給する。 The display unit 6 has liquid crystal or organic EL (Organic Electro-Luminescence), and is used to display the operation key 61 and to display the character string 62 input by the operation key 61. The display control unit 7 causes the display unit 6 to display the operation key 61 and causes the character string 62 input by the operation key 61 to be displayed.

Here, as a touch panel method, there are a resistive film method, a surface acoustic wave method, an electromagnetic induction method, a capacitance method, and the like, and in a communication terminal such as a smartphone, a capacitance method is mainly adopted. The capacitance method is a method of detecting a position by capturing a change in capacitance between a finger and a conductive film. The input control unit 9 outputs input information based on the coordinate information output from the touch panel unit 8. The power supply circuit unit 10 supplies power to each part of the apparatus body.
　制御部１１は、入力制御部９から出力された入力情報より、タッチパネル部８に対するユーザの手指によるタッチが表示部６の表示をスクロールさせるためのスクロール操作である場合、操作キー６１を非表示とする情報を表示制御部７に送る。また、制御部１１は、スクロール操作があった場合、スクロールの方向（下方向又は上方向）を記憶部５に記憶させる。また、制御部１１は、スクロール操作の開始時にタイマ部３のカウントをゼロにしてカウントをスタートさせ、タイマ部３に設定した時間内にタッチパネル部８に対するユーザの手指によるタッチが無かった場合、操作キー６１を再表示する情報を表示制御部７に送る。この際、制御部１１は当該情報にスクロール操作の方向を含める。 Based on the input information output from the input control unit 9, the control unit 11 does not display the operation key 61 when the touch by the user's finger on the touch panel unit 8 is a scroll operation for scrolling the display of the display unit 6. Information to the display control unit 7. In addition, when there is a scroll operation, the control unit 11 causes the storage unit 5 to store the scroll direction (downward or upward). Further, at the start of the scroll operation, the control unit 11 sets the count of the timer unit 3 to zero and starts the count operation, and when there is no touch by the user's finger on the touch panel unit 8 within the time set in the timer unit 3, the operation Information for redisplaying the key 61 is sent to the display control unit 7. At this time, the control unit 11 includes the direction of the scroll operation in the information.
　表示制御部７は、制御部１１から操作キー６１を非表示とする情報を受けると、表示部６において操作キー６１を非表示とする。また、表示制御部７は、制御部１１から操作キー６１を再表示とする情報を受けると、操作キー６１を再表示する。この際、表示制御部７は、操作キー６１を再表示とする情報に含まれるスクロール操作の方向が下方向であった場合、スクロール後に表示部６の上端部付近に表示されていた文字列が維持されるように操作キー６１を再表示させる。一方、スクロール操作の方向が上方向であった場合、表示制御部７は、スクロール後に表示部６の下端部付近に表示されていた文字列が維持されるように操作キー６１を再表示させる。 When the display control unit 7 receives information from the control unit 11 to hide the operation key 61, the display control unit 7 hides the operation key 61 on the display unit 6. In addition, when the display control unit 7 receives the information for redisplaying the operation key 61 from the control unit 11, the display control unit 7 redisplays the operation key 61. At this time, when the direction of the scroll operation included in the information for redisplaying the operation key 61 is downward, the display control unit 7 displays the character string displayed near the upper end of the display unit 6 after the scroll. The operation key 61 is redisplayed so as to be maintained. On the other hand, when the direction of the scroll operation is upward, the display control unit 7 causes the operation key 61 to be displayed again so that the character string displayed near the lower end of the display unit 6 after scrolling is maintained.
　ここで、操作キー６１を非表示としてから再表示するまでの処理について図を用いて説明する。
　図２（ａ）～（ｄ）は、下方向にスクロールを行った場合の表示部６の表示の様子を示す図である。図２の（ａ）は、メール作成等の文字入力中の状態を示しており、操作キー６１そのものと操作キー６１により入力された文字列６２とが共に表示されている。図２の（ｂ）に示すように、文章入力操作中にスクロール動作が実施されると、図２の（ｃ）に示すように、操作キー６１が非表示となり、表示エリアが大きくなる。下方向にスクロールを行うことで、過去に遡って入力した文字列が表示されて行くことになる。スクロール終了後、図２の（ｄ）に示すように、操作キー６１が再表示される。このとき、表示部６の上端部付近に表示されていた文字列が維持されるように操作キー６１が再表示される。 Here, the processing from the non-display of the operation key 61 to the re-display will be described with reference to the drawings.
FIGS. 2 (a) to 2 (d) are diagrams showing display states of the display unit 6 when scrolling is performed downward. (A) of FIG. 2 shows a state during character input such as mail creation, and the operation key 61 itself and the character string 62 input by the operation key 61 are displayed together. As shown in (b) of FIG. 2, when the scroll operation is performed during the text input operation, as shown in (c) of FIG. 2, the operation key 61 is hidden and the display area is enlarged. By scrolling downward, the character string entered retroactively will be displayed. After the end of the scroll, the operation key 61 is displayed again as shown in (d) of FIG. At this time, the operation key 61 is redisplayed so that the character string displayed near the upper end of the display unit 6 is maintained.
　図３（ａ）～（ｄ）は、上方向にスクロールを行った場合の表示部６の表示の様子を示す図である。図３の（ａ）は、メール作成等の文字入力中の状態を示しており、操作キー６１そのものと操作キー６１により入力された文字列６２とが共に表示されている。図３の（ｂ）に示すように、文章入力操作中にスクロール動作が実施されると、図３の（ｃ）に示すように、操作キー６１が非表示となり、表示エリアが大きくなる。上方向にスクロールを行うことで、最後に入力した文字列に向けて文字列が表示されて行く。スクロール終了後、図３の（ｄ）に示すように、操作キー６１が再表示される。このとき、表示部６の下端部付近に表示されていた文字列が維持されるように操作キー６１が再表示される。 FIGS. 3 (a) to 3 (d) are diagrams showing display states of the display unit 6 when scrolling is performed in the upward direction. (A) of FIG. 3 shows a state in which a character is being input such as mail creation, and the operation key 61 itself and the character string 62 input by the operation key 61 are displayed together. As shown in (b) of FIG. 3, when the scroll operation is performed during the text input operation, as shown in (c) of FIG. 3, the operation key 61 is hidden and the display area is enlarged. By scrolling upward, the text is displayed toward the last entered text. After the end of the scroll, the operation key 61 is redisplayed as shown in (d) of FIG. At this time, the operation key 61 is redisplayed so that the character string displayed near the lower end of the display unit 6 is maintained.
　このように、スクロール操作中に操作キー６１を非表示にすることで、操作性、視認性の向上が図れる。また、画面サイズや表示エリアに制限がある通信端末でも画面サイズを有効に使用することが可能となる。なお、スクロール中に文字等の入力を行うことは現実的には不可能であるので、操作キー６１を非表示にしてもユーザの利便性に悪影響はない。また、スクロール操作終了後、操作キー６１を再表示するので、即座にキー入力を再開することができる。また、スクロール操作の方向が下方向であれば、文字列の上半分が残るように操作キー６１を再表示し、スクロール操作の方向が上方向であれば、文字列の下半分が残るように操作キー６１を再表示することから、スクロール操作終了時にユーザが着目していた文字列の部分が操作キーに隠されてしまうことがない。 As described above, by hiding the operation key 61 during the scroll operation, operability and visibility can be improved. In addition, it is possible to effectively use the screen size even in a communication terminal having a restriction on the screen size and the display area. Note that since it is practically impossible to input characters and the like during scrolling, the convenience of the user is not adversely affected even if the operation key 61 is not displayed. In addition, since the operation key 61 is displayed again after the end of the scroll operation, key input can be resumed immediately. Also, if the direction of the scroll operation is downward, the operation key 61 is displayed again so that the upper half of the character string remains, and if the direction of the scroll operation is upward, the lower half of the character string remains. Since the operation key 61 is displayed again, the portion of the character string focused by the user at the end of the scroll operation is not hidden by the operation key.
　因みに、操作キー６１は文字列入力に必要なものであるため、従来技術ではスクロールを行っても操作キー６１が表示され続けていた。そのため、画面サイズに制限のある通信端末では表示エリアが小さくなり、長い文字列を確認しながら文字列を入力することが困難であった。これに対して、本発明では、文字入力中にスクロール動作を検出すると、操作キー６１を非表示にして表示エリアを大きくするので、長い文字列の確認も容易に行うことが可能となる。 Incidentally, since the operation key 61 is necessary for character string input, the operation key 61 continues to be displayed even if scrolling is performed in the prior art. Therefore, in a communication terminal having a limited screen size, the display area becomes smaller, and it is difficult to input a character string while checking a long character string. On the other hand, in the present invention, when the scroll operation is detected during character input, the operation key 61 is not displayed and the display area is enlarged, so it is possible to easily confirm a long character string.
　次に、本実施の形態の通信端末１のタッチパネル装置２０の動作について説明する。
　図４は、タッチパネル装置２０の動作を説明するためのフローチャートである。同図において、まず制御部１１は、入力制御部９からの入力情報よりタッチパネル入力の有無を判定する（ステップＳ１）。タッチパネル入力が無ければ、タッチパネル入力が有るまでこのステップＳ１における判定を繰り返す。タッチパネル入力が有れば、その入力がスクロール動作を示すものであるかどうか判定し（ステップＳ２）、スクロール動作を示すものであると判断すると（ステップＳ２でＹＥＳと判断すると）、制御部１１は、表示部６に表示している操作キー６１を非表示にする（ステップＳ３）。すなわち、制御部１１は、操作キー６１を非表示とする情報を表示制御部７へ送る。表示制御部７は、制御部１１から操作キー６１を非表示とする情報を受けると、表示部６において操作キー６１を非表示とする。 Next, the operation of touch panel device 20 of communication terminal 1 of the present embodiment will be described.
FIG. 4 is a flowchart for explaining the operation of the touch panel device 20. In the figure, first, the control unit 11 determines the presence or absence of touch panel input from the input information from the input control unit 9 (step S1). If there is no touch panel input, the determination in step S1 is repeated until there is a touch panel input. If there is a touch panel input, it is determined whether or not the input indicates a scroll operation (step S2), and if it is determined that the input indicates a scroll operation (YES in step S2), the control unit 11 , Hide the operation key 61 displayed on the display unit 6 (step S3). That is, the control unit 11 sends the information for making the operation key 61 non-display to the display control unit 7. When the display control unit 7 receives information from the control unit 11 to hide the operation key 61, the display control unit 7 hides the operation key 61 on the display unit 6.
　次いで、制御部１１は、スクロール方向を記憶部５に記憶し（ステップＳ４）、タイマ部３のカウントを“０”に設定し、その後、カウントをスタートさせる（ステップＳ５）。制御部１１は、カウントをスタートした後、タイマ部３で設定した時間内にタッチパネル部８への入力があったかどうか判定する（ステップＳ６）。タイマ部３で設定した時間以内にタッチパネル部８への入力があったと判断すると（ステップＳ６でＹＥＳと判断した場合）、その入力がスクロール動作を示すものであるかどうかを判定し（ステップＳ７）、スクロール動作を示すものであると判断すると（ステップＳ７でＹＥＳと判断すると）、ステップＳ４に戻り、スクロール動作を示すものでないと判断すると（ステップＳ７でＮＯと判断すると）、ステップＳ５に戻る。 Next, the control unit 11 stores the scroll direction in the storage unit 5 (step S4), sets the count of the timer unit 3 to "0", and then starts the count (step S5). After starting the counting, the control unit 11 determines whether or not there is an input to the touch panel unit 8 within the time set by the timer unit 3 (step S6). When it is determined that there is an input to touch panel unit 8 within the time set by timer unit 3 (when it is determined as YES in step S6), it is determined whether the input indicates a scroll operation (step S7) If it is determined that the scroll operation is indicated (YES at step S7), the process returns to step S4, and if it is determined that the scroll operation is not indicated (NO at step S7), the process returns to step S5.
　これに対して、タイマ部３で設定した時間を超えてタッチパネル部８への入力が無いと判断すると（ステップＳ６でＮＯと判断すると）、制御部１１は、操作キー６１を再表示する。すなわち、制御部１１は、操作キー６１を表示する情報を表示制御部７へ送る。表示制御部７は、制御部１１から操作キー６１を再表示とする情報を受けると、表示部６において操作キー６１を再表示する。この際、表示制御部７は、操作キー６１を再表示とする情報に含まれるスクロール操作の方向（記憶部５に記憶されているスクロール方向）が下方向であった場合、スクロール後に表示部６の上端部付近に表示されていた文字列が維持されるように操作キー６１を再表示させる。また、スクロール操作の方向（記憶部５に記憶されているスクロール方向）が上方向であった場合、表示制御部７は、スクロール後に表示部６の下端部付近に表示されていた文字列が維持されるように操作キー６１を再表示させる（ステップＳ８）。制御部１１は、操作キー６１を再表示した後、本処理を終える。一方、上記ステップＳ２の判定で、タッチパネル入力がスクロール動作を示すものでないと判断すると（ステップＳ２でＮＯと判断すると）、通常のキー入力処理を実施する（ステップＳ９）。通常のキー入力処理の実施後、本処理を終える。 On the other hand, when it is judged that the time set by the timer unit 3 has not been input to the touch panel unit 8 (NO in step S6), the control unit 11 redisplays the operation key 61. That is, the control unit 11 sends information for displaying the operation key 61 to the display control unit 7. When the display control unit 7 receives the information for redisplaying the operation key 61 from the control unit 11, the display control unit 7 causes the display unit 6 to redisplay the operation key 61. At this time, when the direction of the scroll operation (the scroll direction stored in the storage unit 5) included in the information for redisplaying the operation key 61 is downward, the display control unit 7 displays the display unit 6 after scrolling. The operation key 61 is re-displayed so that the character string displayed near the upper end portion of the is maintained. In addition, when the direction of the scroll operation (the scroll direction stored in the storage unit 5) is upward, the display control unit 7 maintains the character string displayed near the lower end of the display unit 6 after scrolling. The operation key 61 is redisplayed so as to be displayed (step S8). After redisplaying the operation key 61, the control unit 11 ends the present process. On the other hand, if it is determined in step S2 that the touch panel input does not indicate a scroll operation (NO in step S2), the normal key input process is performed (step S9). After execution of the normal key input process, the present process is ended.
　このように本実施の形態の通信端末１によれば、タッチパネル装置２０は、スクロール操作が行われると操作キー６１を非表示にし、スクロール操作が終わると、操作キー６１を再表示するので、スクロール操作中は操作性、視認性の向上が図れ、スクロール操作後は即座にキー入力を再開することができる。また、スクロール操作が行われると操作キー６１を非表示にすることで、画面サイズや表示エリアに制限がある通信端末でも画面サイズを有効に使用することができる。また、操作キー６１の再表示時には、それ以前のスクロール操作の方向が下方向であれば、文字列の上半分が残るように操作キー６１を再表示し、操作キーの再表示以前のスクロール操作の方向が上方向であれば、文字列の下半分が残るように操作キー６１を再表示するので、スクロール操作終了時にユーザが着目していた文字列の部分が操作キーに隠されてしまうことがない。 As described above, according to the communication terminal 1 of the present embodiment, the touch panel device 20 hides the operation key 61 when the scroll operation is performed, and redisplays the operation key 61 when the scroll operation is completed. During operation, operability and visibility can be improved, and key input can be resumed immediately after the scroll operation. In addition, when the scroll operation is performed, by hiding the operation key 61, the screen size can be effectively used even in the communication terminal having the screen size and the display area limited. Also, when the operation key 61 is redisplayed, if the direction of the previous scroll operation is downward, the operation key 61 is redisplayed so that the upper half of the character string remains, and the scroll operation before the operation key is redisplayed If the direction of is the upper direction, the operation key 61 is redisplayed so that the lower half of the character string remains, so the portion of the character string that the user focused on at the end of the scroll operation may be hidden in the operation key There is no
　なお、本実施の形態の通信端末１のタッチパネル装置２０のハード構成としては、通常のコンピュータを用いることもできる。すなわち、タッチパネル装置２０は、ＣＰＵ、ＲＡＭ等の揮発性メモリ、及びＲＯＭ等の不揮発性メモリ、及びハードディスク又はＳＳＤ（Solid State Drive）等の大容量記憶装置等を備えたコンピュータによって構成できる。 As a hardware configuration of touch panel device 20 of communication terminal 1 of the present exemplary embodiment, a normal computer can also be used. That is, the touch panel device 20 can be configured by a computer provided with a CPU, a volatile memory such as a RAM, a nonvolatile memory such as a ROM, and a large capacity storage device such as a hard disk or a solid state drive (SSD).
　また、本実施の形態の通信端末１のタッチパネル装置２０における処理を記述したプログラムを、磁気ディスク、光ディスク、光磁気ディスク、半導体メモリ等の記憶媒体に格納して配布することが可能である。 Moreover, it is possible to store and distribute the program describing the process in the touch panel device 20 of the communication terminal 1 of the present embodiment in a storage medium such as a magnetic disk, an optical disk, a magneto-optical disk, a semiconductor memory.
