When the icon is dragged, a CPU 100 performs a reduced screen display process which reduces display screens of the displays 11 and 21 to be displayed in a display in which a drag operation is carried out. When the drag operation is completed, the reduced display screens are restored to an original size. On the display screen of the original size, the icon is displayed in a position corresponding to the position on the reduced display screen where the drag operation is completed.

Description

  The present invention relates to a mobile terminal device such as a mobile phone or a PDA (Personal Digital Assistant).

  Generally, in a mobile phone, an operation screen, a mail document, a television image, and the like are displayed on a display such as a liquid crystal panel. If the display is large, a large amount of information (documents, etc.) can be displayed at once, or a TV image can be projected greatly. However, on the other hand, when the display becomes large, the size of the device itself becomes large, which becomes an obstacle when carrying it.

  Therefore, in view of such a problem, a first display that is always exposed to the outside, and a second display that is housed in the device main body and exposed to the outside as necessary when being carried or the like are provided. A mobile phone that can display an image on a single display surface in which two displays are integrated can be considered (for example, Patent Document 1).

JP 2002-44202 A

  Recently, mobile phones on which various applications are executed by touching an icon displayed on the display with a finger or the like are arranged on the display. In such a cellular phone, the icon can be moved to a desired position on the screen by performing a drag operation.

  A mobile phone including the above two displays can also be configured such that a touch panel is provided on each display and operation input using the touch panel can be performed. In this case, the icon can be moved by a drag operation between the first display and the second display.

  However, there is usually a portion of the cabinet that houses the display between the first display and the second display. For this reason, in the case of the drag operation, since the contact of the finger or the like with the display surface is once cut off in the cabinet portion, it is difficult to detect that the drag operation has been performed between the two displays.

  Therefore, even if the icon is dragged from one display to the other display, it is erroneously determined that the drag operation is completed at one end of one display, and the icon may remain at that end. There is.

  The present invention has been made in view of such problems, and an object of the present invention is to provide a portable terminal device that can perform a drag operation between two display units with high accuracy.

The portable terminal device of the present invention controls the display of the first display unit, the second display unit aligned with the first display unit, and the first display unit and the second display unit. A display control unit; and a detection unit for detecting that a drag operation has been performed on the movement target displayed on the first display unit or the second display unit. Here, when the movement target is being dragged, the display control unit reduces the display screen displayed on the first display unit and the second display unit, and displays the reduced display screen on the display unit. Reduced screen display processing to be displayed on the display unit where the drag operation is performed is executed. When the drag operation is completed, the reduced display screen is returned to the original size display screen and displayed on the first display unit and the second display unit. In the original size display screen, The movement target is displayed at a position corresponding to the position at the completion of the drag operation on the reduced display screen.

  According to the configuration of the present invention, when the drag operation is performed between the two display units, the drag operation is not performed on the portion where the display unit is interrupted, so that the drag operation can be easily detected. . Therefore, the drag operation between the two display units can be performed with high accuracy.

  In the mobile terminal device of the present invention, the display control unit may be configured to execute the reduced screen display process when the drag operation is started.

  With such a configuration, a reduced screen display process is always executed when a drag operation is performed.

  In the mobile terminal device of the present invention, the display control unit may be configured to execute the reduced screen display process based on the state of the drag operation.

  For example, the display control unit may be configured to execute the reduced screen display process when the drag operation reaches within a predetermined range from a boundary with the other display unit.

  Alternatively, the display control unit may be configured to execute the reduced screen display process when the drag operation is performed in the direction of the other display unit.

  With such a configuration, when it is highly possible that a drag operation is performed between the two display units, the reduced screen display process is executed. Therefore, when the drag operation is performed within the range of one display unit, the operation can be performed in the original size state.

  In the mobile terminal device of the present invention, the display control unit may be configured to execute the reduced screen display process when a predetermined key operation is performed after the drag operation is started.

  With such a configuration, when the user performs a drag operation between the two display units, the reduced screen display process is executed by the user's key operation. Therefore, when the user tries to perform a drag operation within the range of one display unit, the user can perform the operation in the original size state.

  In the mobile terminal device of the present invention, the display control unit may be configured to stop the display control process based on the drag operation and perform an incoming call notification when there is an incoming call during the drag operation.

  With such a configuration, when an incoming call is received during a drag operation, the user can quickly answer the call. Further, it is possible to prevent the user from moving the movement target to an undesired position in response to an incoming call.

  In the mobile terminal device of the present invention, the display control unit may be configured to notify an incoming call after completion of the drag operation when an incoming e-mail is received during the drag operation.

  With such a configuration, the user can perform a drag operation without being disturbed by an incoming e-mail notification. Further, after the drag operation is completed, it is possible to know that an e-mail has been received.

  ADVANTAGE OF THE INVENTION According to this invention, the portable terminal device which can perform the drag operation between two display parts with sufficient precision can be provided.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a diagram (disassembled perspective view) illustrating a configuration of a mobile phone. The cellular phone includes a first cabinet 1, a second cabinet 2, and a holder 3 that holds the first and second cabinets 1 and 2.

  The first cabinet 1 has a horizontally long rectangular parallelepiped shape. A first display 11 is arranged in the first cabinet 1, and its display surface faces the front of the first cabinet 1. As will be described later, the first display 11 includes a first liquid crystal panel 11a and a first backlight 11b that illuminates the first liquid crystal panel 11a.

  A first touch panel 12 is disposed on the front surface of the first display 11. The first touch panel 12 has a transparent sheet shape, and a display screen displayed on the display 11 can be seen through the first touch panel 12.

  The first touch panel 12 includes a first transparent electrode and a second transparent electrode arranged in a matrix. The first touch panel 12 detects a position on the display surface touched by the user by detecting a change in capacitance between the transparent electrodes, and outputs a position signal corresponding to the position. The first touch panel 12 is not limited to a capacitive touch panel, and may be a resistive film type, pressure sensitive type touch panel, or the like.

  Inside the first cabinet 1, a camera module 13 is arranged at a slightly rear position in the center. A lens window (not shown) for capturing a subject image in the camera module 13 is provided on the lower surface of the first cabinet 1. Inside the first cabinet 1, a magnet 14 is disposed at a central position near the front surface, and a magnet 15 is disposed at the right front corner. Further, protrusions 16 and 17 are provided on the right side surface and the left side surface of the upper cabinet 1, respectively.

  The second cabinet 2 has a horizontally long rectangular parallelepiped shape. That is, the second cabinet 2 has substantially the same shape and size as the first cabinet 1. A second display 21 is arranged in the second cabinet 2, and the display surface faces the front of the second cabinet 2. As will be described later, the second display 21 includes a second liquid crystal panel 21a and a second backlight 21b that illuminates the second liquid crystal panel 21a. In addition, the 1st display 11 and the 2nd display 21 may be comprised by other display elements, such as organic EL.

  A second touch panel 22 is disposed on the front surface of the second display 21. The configuration of the second touch panel 22 is the same as that of the first touch panel 12.

Inside the second cabinet 2, a magnet 23 is arranged at a central position near the rear surface.
When the magnet 23 and the magnet 14 of the first cabinet 1 are in a state (second display state) in which the first cabinet 1 and the second cabinet 2 are positioned at positions that constitute a large screen as will be described later. It is configured to attract. In the first cabinet 1 and the second cabinet 2, if the magnetic force of one magnet is sufficiently large, the other magnet may be replaced with a magnetic material.

Inside the second cabinet 2, a closing sensor 24 is disposed at the right front corner, and an opening sensor 25 is disposed at the right rear corner. These sensors 24 and 25 are composed of, for example, a Hall IC and output detection signals in response to the magnetic force of the magnet. As will be described later, when the first cabinet 1 and the second cabinet 2 overlap with each other, the magnet 15 of the first cabinet 1 approaches the closing sensor 24, so that an ON signal is output from the closing sensor 24. On the other hand, when the first cabinet 1 and the second cabinet 2 are arranged side by side, the magnet 15 of the first cabinet 1 approaches the open sensor 25, so that an ON signal is output from the open sensor 25.

  Further, two shaft portions 26 are provided on the right side surface of the second cabinet 2, and two shaft portions 27 are provided on the left side surface.

  The holding body 3 includes a bottom plate portion 31, a right holding portion 32 formed at the right end portion of the bottom plate portion 31, and a left holding portion 33 formed at the left end portion of the bottom plate portion 31. The first cabinet 1 and the second cabinet 2 are accommodated in the accommodation region R surrounded by the bottom plate portion 31, the right holding portion 32 and the left holding portion 33 in a state where they overlap each other.

  Three coil springs 34 are arranged on the bottom plate portion 31 so as to be arranged in the left-right direction. These coil springs 34 abut against the lower surface of the second cabinet 2 in a state in which the second cabinet 2 is attached to the holding body 3, and apply a force to push up the second cabinet 2.

  A microphone 35 and a power key 36 are arranged on the upper surface of the right holding part 32. An operation key group 37 is disposed on the outer side surface of the right holding portion 32. The operation key group 37 includes a plurality of keys such as a manner mode setting key. Certain functions are executed without operating the touch panels 12 and 22 by operating these operation keys. A call speaker 38 is arranged on the upper surface of the left holding portion 33. The user makes a call by holding the mobile phone so that the left holding unit 33 side is at the ear and the right holding unit 32 side is at the mouth.

  Guide grooves 39 (shown only on the left holding portion 33 side) are formed on the inner side surfaces of the right holding portion 32 and the left holding portion 33. The guide groove 39 includes an upper groove 39a and a lower groove 39b extending in the front-rear direction, and two vertical grooves 39c formed on the front side of the groove and extending vertically so as to be connected to the upper groove 39a and the lower groove 39b.

  When assembling the mobile phone, the second cabinet 2 is disposed in the housing region R of the holding body 3 so that the shaft portions 26 and 27 are inserted into the lower groove 39b of the guide groove 39, and the projection 16 , 17 are inserted into the upper groove 39a of the guide groove 39, and the first cabinet 1 is disposed on the second cabinet 2 in the housing region R of the holding body 3.

  Thus, the first cabinet 1 is guided by the upper groove 39a and can slide back and forth. Further, the second cabinet 2 is guided by the lower groove 39b and can slide back and forth. When the second cabinet 2 moves forward and the shaft portions 26 and 27 reach the vertical groove 39c, the second cabinet 2 is guided by the vertical groove 39c and can slide up and down.

  FIG. 2 is a diagram for explaining a switching operation from the first display state by the first display 11 to the second display state by the first display 11 and the second display 21.

  In the initial state, the second cabinet 2 is hidden behind the first cabinet 1 as shown in FIG. In this state, only the first display 11 is exposed to the outside. This state is referred to as a “first display state”. The switching operation is manually performed by the user.

  First, the user moves the first cabinet 1 backward as shown in FIG. Next, when the rearward movement of the first cabinet 1 is completed, the second cabinet 2 is pulled forward as shown in FIG. When the second cabinet 2 is moved to a position where the second cabinet 2 does not completely overlap the first cabinet 1, that is, a position aligned in front of the first cabinet 1, by this pulling operation, the shaft portions 26 and 27 are inserted into the vertical grooves 39c as described above. Therefore, the second cabinet 2 is pushed up by the coil spring 33 and moves up. At this time, the magnet 14 and the magnet 23 are attracted to each other, so that a larger ascending force works. Thus, as shown in FIG. 4D, the first cabinet 1 and the second cabinet 2 are arranged so as to be in close contact with each other in the front-rear direction. The first display 11 and the second display 21 are integrated into a large screen state. This state is referred to as a “second display state”.

  FIG. 3 is a block diagram showing the overall configuration of the mobile phone. In addition to the components described above, the cellular phone according to the present embodiment includes a CPU 100, a memory 200, a video encoder 301, an audio encoder 302, a key input circuit 303, a communication circuit 304, a backlight drive circuit 305, a video decoder 306, an audio A decoder 307 and an external speaker 308 are provided.

  The camera module 13 has an image sensor such as a CCD. The camera module 13 digitizes the image signal output from the image sensor, performs various corrections such as gamma correction on the image signal, and outputs the image signal to the video encoder 301. The video encoder 301 encodes the imaging signal from the camera module 13 and outputs the encoded signal to the CPU 100.

  The microphone 35 converts the collected sound into a sound signal and outputs the sound signal to the sound encoder 302. The audio encoder 302 converts an analog audio signal from the microphone 35 into a digital audio signal, encodes the digital audio signal, and outputs it to the CPU 100.

  The key input circuit 303 outputs an input signal corresponding to each key to the CPU 100 when each key of the power key 36 and the operation key group 37 is operated.

  The communication circuit 304 converts transmission data such as an audio signal, an image signal, and a text signal from the CPU 100 into a radio signal, and transmits the radio signal to the base station via the antenna 304a. In addition, a radio signal received via the antenna 304a is converted into reception data such as an audio signal, an image signal, and a text signal and output to the CPU 100.

  The backlight drive circuit 305 supplies a voltage signal corresponding to the control signal from the CPU 100 to the first backlight 11b and the second backlight 21b. The first backlight 11b is turned on by a voltage signal from the backlight driving circuit 305 and illuminates the first liquid crystal panel 11a. The second backlight 21b is turned on by a voltage signal from the backlight driving circuit 305 and illuminates the second liquid crystal panel 21a.

  The video decoder 306 converts the video signal from the CPU 100 into an analog or digital video signal that can be displayed on the first liquid crystal panel 11a and the second liquid crystal panel 21a, and outputs the analog or digital video signal to the liquid crystal panels 11a and 21a. The first liquid crystal panel 11a and the second liquid crystal panel 21a display an image (display screen) corresponding to the video signal on each display surface.

  The audio decoder 307 performs decoding processing on the audio signal from the CPU 100, further converts the audio signal into an analog audio signal, and outputs the analog audio signal to the call speaker 38. Also, the audio decoder 307 performs decoding processing on sound signals of various notification sounds such as a ring tone and an alarm sound from the CPU 100, converts the sound signals into analog sound signals, and outputs the analog sound signals to the external speaker 308. The call speaker 38 reproduces the audio signal from the audio decoder 307 as audio. The external speaker 308 reproduces a ring tone from the audio decoder 307 and the like.

  The memory 200 includes a ROM and a RAM. The memory 200 stores a control program for giving a control function to the CPU 100. The memory 200 stores image data captured by the camera module 13, image data captured from the outside via the communication circuit 304, text data (mail data), and the like in a predetermined file format.

  The CPU 100 controls the camera module 13, the microphone 35, the communication circuit 304, the liquid crystal panels 11a and 21a, the call speaker 38, the external speaker 308, and the like according to the control program based on the operation input signals from the key input circuit 303 and the touch panels 12 and 22. Make it work. As a result, various functions (applications) such as a call function and an e-mail function are executed.

  Further, the CPU 100 generates a display screen to be displayed on each of the displays 11 and 21 within a work area prepared in the memory 200, and outputs a video signal for configuring the display screen.

  FIG. 4 is a diagram illustrating a screen display example on the first display 11 and the second display 21.

  When the second cabinet 2 is closed, a display screen is displayed on the first display 11. For example, a menu screen is displayed on the first display 11 as an initial screen. For example, as shown in FIG. 4A, icons for executing various applications are displayed on the menu screen. The application can be obtained by downloading or the like through the Internet, and the obtained application is added to the mobile phone by installation. When the number of applications increases and the corresponding icons increase, all icons cannot be displayed on one display screen. In this case, as shown in FIG. 4B, when the second cabinet 2 is opened and the second display state is established by the first display 11 and the second display 21, icons that could not be displayed on the first display 11 are displayed. Displayed on the second display 21.

  The icons displayed on the displays 11 and 21 can be moved to a desired position by a drag operation. In the present embodiment, not only the range of one display but also the icon can be moved between the first display 11 and the second display 21 by a drag operation. For example, icons of frequently used applications can be displayed on the first display 11. When the use frequency decreases, the icon of the application can be moved to the second display 21 by a drag operation.

  FIG. 5 is a flowchart showing display control processing when a drag operation is performed in the second display state. FIG. 6 is a diagram illustrating a screen display example when a drag operation from the first display 11 to the second display 21 is performed. Hereinafter, the processing operation will be described with reference to an example in which a drag operation is performed on an icon displayed on the first display 11.

  Referring to FIG. 5, CPU 100 acquires signals from touch panels 12 and 22 (S1), and detects whether or not the signals are position signals (S2). For example, when the user drags an icon displayed on the first display 11 and touches the icon, a position signal based on the touched position is output from the first touch panel 12. The position signal includes a signal indicating a vertical position (coordinate) on the display and a signal indicating a horizontal position (coordinate).

  When detecting the position signal from the first touch panel 12 (S2: YES), the CPU 100 determines whether or not there is an icon (movement target) at the detected position (S3). If it is determined that there is an icon at the detected position (S3: YES), the signal from the first touch panel 12 is acquired again (S4), and it is detected whether the signal is a position signal (S5). . If the position signal is subsequently detected (S5: YES), the CPU 100 determines whether or not a drag operation has been performed on the icon (S6). The CPU 100 compares the current detection position with the previous detection position, and determines that a drag operation has been performed if they are different.

  When the icon is dragged by the user (see FIG. 6A), when the CPU 100 determines that the drag operation has been performed (S6: YES), the CPU 100 executes a reduced screen display process. That is, the CPU 100 moves up and down the display screen (hereinafter referred to as “first screen”) displayed on the first display 11 and the display screen (hereinafter referred to as “second screen”) displayed on the second display 21. Is reduced to half, so that both display screens can be displayed on one display (S7). Then, both the first screen and the second screen are displayed on the display on which the drag operation is performed, that is, the first display 11 (S8). At this time, an icon reduced as the display screen is reduced is displayed on the first display 11 (see FIG. 6B). Even when the screen is switched in this way, the drag target icon is maintained at the position touched by the user.

  Next, the CPU 100 acquires the signal from the first touch panel 12 again (S9), and detects whether or not the signal is a position signal (S10). If the position signal is subsequently detected (S10: YES), the dragged icon is moved to the detected position (S11). Thereby, the dragged icon is displayed at the detection position (see FIG. 6B). At this time, the icon displayed at the detection position is the size before the reduction, and is further displayed in a display form (for example, translucent) that can be recognized that the drag operation is being performed. In FIG. 6B, for the sake of convenience, the icon being dragged is indicated by hatching.

  Thereafter, when the drag operation is continued by the user, the CPU 100 repeats the processing from step S9 to step S11. Accordingly, the icon moves on the first display 11 following the drag operation.

  When the user wants to move the dragged icon to the second display 21, as shown in FIG. 6B, the user moves the icon on the second screen. When the icon is dragged to a desired position on the second screen, the finger is released from the first display 11 to complete the drag operation.

  When the user completes the drag operation, the position signal from the first touch panel 12 is not detected. When the position signal is no longer detected in step S10 (S10: NO), CPU 100 determines that the drag operation has been completed, and returns the first screen and the second screen to their original sizes. Then, the first screen is displayed on the first display 11, and the second screen is displayed on the second display 21 (S12). At this time, as shown in FIG. 6C, the CPU 100 erases the dragged icon from the first screen. Then, on the second screen, the dragged icon is displayed at a position corresponding to the position of the icon on the reduced second screen when the drag is completed.

When the user once touches the icon but releases the finger without dragging, the position signal is not detected in step S5 without determining that the drag operation has been performed in step S6 (S6: NO) ( S5: NO). When this happens, the process ends without changing the display on the first display 11.

  Further, as shown in FIG. 6B, the display form of the other display when the two display screens move to one display may be any form. For example, a specific background image (including a single color image such as white) may be displayed, or the previous display screen may be displayed as it is. Alternatively, the display may be turned off.

  As described above, in the present embodiment, when a drag operation of a movement target such as an icon is performed between the first display 11 and the second display 12, a drag operation is performed on a portion of the cabinet where the display is interrupted. Therefore, the drag operation can be easily detected. Therefore, the drag operation between the two displays 11 and 21 can be performed with high accuracy.

  Further, since it is not necessary to actually move two icons between the two displays, it is only necessary to move the icons within one display. Therefore, the moving distance of the icons can be shortened, and the drag operation can be performed quickly.

<Modification 1>
FIG. 7 is a flowchart illustrating display control processing when a drag operation is performed in the second display state according to the first modification. FIG. 8 is a diagram illustrating a screen display example when a drag operation from the first display 11 to the second display 21 is performed according to the first modification.

  In the above embodiment, when the drag operation is started, the reduced screen display process (S7, S8) is always executed. Therefore, even when a drag operation is intended to be performed within the range of one display, the operation is performed on a reduced display screen. In this case, since an image such as an icon becomes small, there is a possibility that the operation is rather difficult.

  Therefore, in the configuration of the first modification, the reduced screen display process (S7, S8) is executed only when the user desires.

  The processing operation will be described below by taking as an example a case where a drag operation is performed on an icon displayed on the first display 11 as in the above embodiment. Here, only processing different from the above embodiment will be described.

  When determining that the drag operation has been performed in step S6, the CPU 100 moves the dragged icon (movement target) to the current detection position (S13). Thereby, the icon dragged to the detection position is displayed in a display form indicating that the drag operation is being performed (see FIG. 8A).

  Next, the CPU 100 determines whether or not an input operation of a predetermined key of the operation key group 37 has been performed (S14). If there is no input operation of a predetermined key (S14: NO), a series of steps S5 → S6 → S13 is repeated. Accordingly, the icon moves on the first display 11 following the drag operation.

  The user does not press a predetermined key when completing the drag operation within the range of the first display 11. Then, when the icon is moved to a desired position, the finger or the like is released from the icon.

  As a result, when position detection is not performed in step S5 (S5: NO), the CPU 100 displays the icon in the normal display form at the last detection position and ends the process.

  On the other hand, when moving the icon to the second display 21, the user presses a predetermined key.

  As a result, when the CPU 100 determines in step S14 that a predetermined key input operation has been performed (S14: YES), the CPU 100 executes reduced screen display processing (S7, S8). Thereby, the reduced first screen and second screen are displayed on the first display 11 (see FIG. 8B). Subsequent processing is the same as in the above embodiment.

  As described above, with the configuration of the first modification, when performing a drag operation within the range of one display, the user can perform the operation in the original size state. Therefore, the image to be moved, such as an icon, is not unnecessarily small, and there is no fear that the operation will be difficult.

<Modification 2>
FIG. 9 is a flowchart illustrating display control processing when a drag operation is performed in the second display state according to the second modification. FIG. 10 is a diagram illustrating a screen display example when a drag operation from the first display 11 to the second display 21 is performed according to the second modification.

  In the configuration of the first modification, the user must perform key operations one by one.

  Therefore, in the configuration of the second modification, a situation in which a drag operation is highly likely to be performed between the first display 11 and the second display 21 is automatically detected. In such a case, a reduced screen display process ( S7, S8) are executed. Here, only processing different from that in the above embodiment and the second modification will be described.

  When the CPU 100 moves the dragged icon to the detection position in step S13 (S13), similarly to the second modification, next, it is determined whether or not the detection position is a position within a preset boundary region. Determine (S15). As shown in FIG. 10A, the boundary region is set at the lower end of the first display 11 and the upper end of the second display 21 that are the ends on the boundary side between the first display 11 and the second display 21. The

  When the user drags the icon to the second display 21 side, the user moves the icon to the lower end of the first display 11 (see FIG. 10A).

  If the CPU 100 determines that the detected position is a position in the boundary area by moving the icon to the boundary area (S15: YES), the CPU 100 executes a reduced screen display process (S7, S8). Thereby, the reduced first screen and second screen are displayed on the first display 11 (see FIG. 10B). Subsequent processing is the same as in the above embodiment.

  As described above, with the configuration of the modification example 2, as in the modification example 1, when the drag operation is performed within the range of one display, the operation can be performed in the original size state. Therefore, the image to be moved, such as an icon, is not unnecessarily small, and there is no fear that the operation will be difficult. In addition, the user does not need to perform key operations one by one.

<Modification 3>
FIG. 11 is a flowchart illustrating display control processing when a drag operation is performed in the second display state according to the third modification.

  In the configuration of the modification example 2, as shown in FIG. 10B, when the reduced screen display process is executed, the icon is positioned at the lower end of the first display 11, so that the desired second screen is displayed. When the icon is moved to a position, the icon is returned upward. Therefore, the movement of the icon is likely to be wasted.

Therefore, in the configuration of the modification example 3, the process of step S16 shown in FIG. 11 is executed instead of the process of step S15 of FIG. It is determined whether or not it has been moved in the direction toward (S16). Here, the CPU 100 compares the previous detection position with the current detection position, and determines that the current position has moved in the boundary direction if the current position is close to the second display 21. If it is determined that the icon has been moved in the boundary direction (S16: YES), reduced screen display processing (S7, S8) is executed.

  In this way, with the configuration of the modification example 3, the reduced screen display process is executed even if the icon is not moved to the end of the display, and then the icon is returned to the inside of the display. Hateful. Therefore, it is possible to make it difficult to waste the icon movement.

<Modification 4>
In the above-described embodiment, the display control process has been described using the case where a drag operation is performed on the icon displayed on the menu screen as a specific example. However, the display control processing shown in FIG. 5 can also be applied to a drag operation on another moving object, for example, a character string designated as a range for a thumbnail or copy of a photo as described below. .

  FIG. 12 is a diagram illustrating a screen display example when the thumbnail displayed on the thumbnail screen of the first display 11 is dragged to the thumbnail screen of the second display 21. The first display 11 and the second display 21 display a thumbnail screen on which a large number of photo thumbnails are arranged.

  When one thumbnail is dragged on the first display 11 (see FIG. 12A), two thumbnail screens are reduced and displayed on the first display 11 (see FIG. 12B). Thereafter, on the first display 11, the dragged thumbnail is moved to a desired position on the lower thumbnail screen, and when the drag operation is completed, the two thumbnail screens are restored to the original size, and each thumbnail screen is restored to the original size. It is displayed on the display 11, 21. At this time, the dragged thumbnail is erased from the first display 11 and displayed on the second display 21 (see FIG. 12C).

  FIG. 13 is a diagram illustrating a screen display example when the thumbnail displayed on the thumbnail screen of the first display 11 is dragged to the photo area displayed on the phone book screen of the second display 21. The first display 11 displays a thumbnail screen, and the second display 21 displays a phone book screen in which the name and telephone number of the other party are described.

  When one thumbnail is dragged on the first display 11 (see FIG. 13A), the thumbnail screen and the phone book screen are reduced and displayed on the first display 11 (see FIG. 13B). Thereafter, the dragged thumbnail is moved to the photo area of the phone book screen on the first display 11, and when the drag operation is completed, the thumbnail screen and the phone book screen are restored to their original sizes, and the original displays 11, 21 are displayed. Is displayed. At this time, the dragged thumbnail is displayed at the original position of the first display 11, and the photo corresponding to the dragged thumbnail is arranged in the photo area of the telephone directory screen displayed on the second display 21. (See FIG. 13C).

  FIG. 14 is a diagram illustrating a screen display example when a character string displayed on the document creation screen of the first display 11 is dragged to the document creation screen of the second display 21. On the first display 11 and the second display 21, a document creation screen for creating a document of the outgoing mail is displayed. The document creation screen on the first display 11 and the document creation screen on the second display 21 are continuous. The text on the lower document creation screen follows the text on the upper document creation screen.

  When a character string whose range is specified as a copy target is dragged on the first display 11 (see FIG. 14A), the two document creation screens are reduced and displayed on the first display 11 (FIG. 14 ( b)). Thereafter, the dragged character string is moved to a desired position on the lower document creation screen on the first display 11, and when the drag operation is completed, the two document creation screens are restored to the original size, and each document creation is performed. The screen is displayed on the original displays 11 and 21. At this time, the dragged character string is displayed at the original position on the first display 11, and a copy of the character string is displayed on the second display 21 (see FIG. 14C).

  FIG. 15 is a diagram illustrating a screen display example when the character string displayed on the detailed display screen of the first display 11 is dragged to the document creation screen of the second display 21. The first display 11 displays a detailed display screen in which the text of the received mail is written, and the second display 21 displays a document creation screen for creating a document of the transmitted mail.

  When a character string whose range is specified as a copy target is dragged on the first display 11 (see FIG. 15A), the detailed display screen and the document creation screen are reduced and displayed on the first display 11 (FIG. 15). 15 (b)). Thereafter, the dragged character string is moved to a desired position on the document creation screen on the first display 11, and when the drag operation is completed, the detail display screen and the document creation screen are returned to their original sizes, and the original display 11 and 21. At this time, the dragged character string is displayed on the second display 21 while the original character string is displayed on the first display 11 (see FIG. 15C).

  FIG. 16 is a diagram illustrating a screen display example when the character string displayed on the detailed display screen of the first display 11 is dragged to the web screen of the second display 21. The first display 11 displays a detailed display screen on which the text of the received mail is written, and the second display 21 displays an Internet web screen.

  For example, the case where the term described on the detailed display screen is searched on the web screen is taken as an example. When the range-designated character string (term) is dragged on the first display 11 (see FIG. 16A), the detailed display screen and the web screen are reduced and displayed on the first display 11 (FIG. 16). (See (b)). Thereafter, the dragged character string is moved to the search text box on the web screen on the first display 11, and when the drag operation is completed, the detail display screen and the web screen are returned to the original size, and the original display 11, 21. At this time, the dragged character string is displayed at the original position on the first display 11, and a copy of the character string is arranged in the search text box on the web screen displayed on the second display 21 (FIG. 16). (See (c)).

  Note that the display control processing shown in FIGS. 7, 9, and 11 can also be applied to the examples of FIGS.

<Modification 5>
FIG. 17 is a flowchart showing a control process in the case of an interruption such as an incoming call during the drag operation according to the fifth modification.

  This control processing is executed by the CPU 100 in parallel with the display control processing of FIGS. 5, 7, 9 and 11 described above.

  When the drag operation is started (S21: YES), the CPU 100 determines whether an incoming call has been received, whether an e-mail has been received, and whether an alarm notification time has been reached until the drag operation is completed. Monitor (S22 → S25 → S28 → S29).

  When the CPU 100 determines that an incoming call has been received during the drag operation (S22: YES), the CPU 100 stops the display control process being executed (S23). Then, the incoming call is notified (S24). That is, an incoming call screen including the name and telephone number of the other party is displayed on the first display 11 and the second display 21 and a ring tone is output from the external speaker 308.

  This allows the user to answer the phone quickly.

  On the other hand, when determining that there is an incoming e-mail (S25: YES) or determining that the alarm notification time has elapsed (S28: YES), the CPU 100 determines whether or not the drag operation is completed ( If the drag operation has not been completed (S26: NO), the process waits as it is. When the drag operation is completed (S26: YES), an incoming call is notified in the case of an incoming e-mail (S27). That is, a ring tone is output from the external speaker 308 and an icon indicating an incoming e-mail is displayed on the first display 11 or the second display 21.

  Thereby, the user can perform a drag operation without being disturbed by an incoming e-mail notification or an alarm sound. Furthermore, after the drag operation is completed, it is possible to know that an e-mail has been received and that the alarm notification time has elapsed.

  The icon indicating the incoming e-mail may be displayed in one corner of the first display 11 or the second display 21 during the drag operation.
