  Inside the second cabinet 20, a closing sensor 26 is disposed at the right front corner. The closing sensor 26 is configured by, for example, a Hall IC, and outputs a sensor signal when the magnetic force of the magnet 17 is detected. Since the magnet 17 of the first cabinet 10 approaches the closing sensor 26 in a closed state to be described later, a sensor signal is output from the closing sensor 26 to the CPU 100. On the other hand, since the magnet 17 of the first cabinet 10 is separated from the closing sensor 26 in the open state, no sensor signal is output from the closing sensor 26.

  Two shaft portions 27 are provided on both side surfaces of the second cabinet 20.

  The holding body 30 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.

  Three coil springs 34 are arranged on the bottom plate portion 31 so as to be arranged in the left-right direction. In a state in which the second cabinet 20 is attached to the holding body 30, the coil spring 34 abuts on the lower surface of the second cabinet 20 and applies a force to push up the second cabinet 20.

  A microphone 35 and a power key 36 are arranged on the upper surface of the right holding part 32. A speaker 38 is disposed on the upper surface of the left holding portion 33. A plurality of hard keys 37 are arranged on the outer surface of the right holding part 32.

  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, a lower groove 39b, and two vertical grooves 39c. The upper groove 39a and the lower groove 39b extend in the front-rear direction, and the vertical groove 39c extends vertically so as to connect the upper groove 39a and the lower groove 39b.

  When assembling the mobile phone 1, the shaft portion 27 is inserted into the lower groove 39 b of the guide groove 39, and the second cabinet 20 is disposed in the accommodation region R of the holding body 30. The protrusion 18 is inserted into the upper groove 39 a of the guide groove 39, the first cabinet 10 is disposed on the second cabinet 20, and the first cabinet 10 is accommodated in the accommodation region R of the holding body 30.

  In this manner, the first cabinet 10 and the second cabinet 20 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. In this state, the first cabinet 10 is slidable back and forth while being guided by the upper groove 39a. The second cabinet 20 is guided by the lower groove 39b and can slide back and forth. Further, when the second cabinet 20 moves forward and the shaft portion 27 reaches the vertical groove 39c, the second cabinet 20 is guided by the vertical groove 39c and can slide up and down.

  FIG. 2A to FIG. 2D are diagrams for explaining an operation for switching the mobile phone 1 from the closed state to the open state.

  In the closed state shown in FIG. 2A, the first cabinet 10 is overlaid on the second cabinet 20, and the cellular phone 1 is folded. The closed state corresponds to a first form in which the second display surface 21a1 is covered by the first cabinet 10. In the closed state, only the first display surface 11a1 is exposed to the outside.

  The first cabinet 10 moves rearward in the direction of the arrow shown in FIG. 2B, and the second cabinet 20 is pulled forward in the direction of the arrow shown in FIG. Thereby, when the closing sensor 26 does not detect the magnetic force of the magnet 17 and does not output the sensor signal, the mobile phone 1 is switched to the open state. In this open state, a part of the second display surface 21a1 appears outside.

  When the second cabinet 20 does not completely overlap the first cabinet 10, the shaft portion 27 shown in FIG. 1 comes to the vertical groove 39c. Thereby, the axial part 27 moves along the vertical groove 39c, and the 2nd cabinet 20 becomes movable up and down. At this time, the second cabinet 20 is raised by the elastic force of the coil spring 34 and the attractive force of the magnet 16 and the magnet 25.

As shown in FIG. 2D, the second cabinet 20 is arranged in close contact with the first cabinet 10, and the second display surface 21a1 has the same height as the first display surface 11a1. Thereby, the 1st cabinet 10 and the 2nd cabinet 20 are expanded, and both the 1st display surface 11a1 and the 2nd display surface 21a1 are exposed outside.

  The open state corresponds to a second form in which at least a part of the second display surface 21a1 is exposed to the outside, as shown in FIGS. 2 (b) to 2 (d).

  Further, the projecting portion 18 moves in the upper groove 39a of the guide groove 39 of the guide groove 39, and the shaft portion 27 moves in the lower groove 39b, the vertical groove 39c, and the upper groove 39a, so that the closed state and the open state are switched. For this reason, it is equivalent to the mechanism part which connects the 1st cabinet 10 and the 2nd cabinet 20 so that the projection part 18, the shaft part 27, and the guide groove 39 can switch a closed state and an open state.

  FIG. 3 is a block diagram showing the overall configuration of the mobile phone 1. The mobile phone 1 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 module 304, a backlight drive circuit 305, a video decoder 306, in addition to the above-described components. An audio decoder 307, a battery 309, and a power supply unit 310 are provided.

  The camera module 15 has an image sensor such as a CCD. The camera module 15 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 performs an encoding process on the imaging signal from the camera module 15 and outputs it 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 of the power key 36 and the hard key 37 is pressed.

  The communication module 304 converts data from the CPU 100 into a radio signal and transmits it to the base station via the antenna 304a. Further, the communication module 304 converts a radio signal received via the antenna 304a into data and outputs the data to the CPU 100.

  The backlight drive circuit 305 supplies a drive signal according to a control signal from the CPU 100 to the first panel backlight 11b, the first key backlight 13b, the second panel backlight 21b, and the second key backlight 23b. The first panel backlight 11b, the first key backlight 13b, the second panel backlight 21b, and the second key backlight 23b are turned on by a drive signal from the backlight drive circuit 305, and the first liquid crystal panel 11a, The key cover 13a, the second liquid crystal panel 21a, and the second key cover 23a are illuminated.

  The video decoder 306 converts the image data from the CPU 100 into video signals that can be displayed on the first liquid crystal panel 11a and the second liquid crystal panel 21a, and outputs them to the liquid crystal panels 11a and 21a. The first liquid crystal panel 11a displays an image corresponding to the video signal on the first display surface 11a1. The second liquid crystal panel 21a displays an image corresponding to the video signal on the second display surface 21a1.

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

  The battery 309 is for supplying electric power to the CPU 100 and other parts than the CPU 100, and includes a secondary battery. The battery 309 is connected to the power supply unit 310.

  The power supply unit 310 converts the voltage of the battery 309 into a voltage having a magnitude required for each unit and supplies the voltage to each unit. In addition, the power supply unit 310 supplies power supplied via an external power supply (not shown) to the battery 309 to charge the battery 309.

  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. In such a control program, control for distinguishing the display units 11 and 21 that display the screen in the active state from the display units 11 and 21 that display the screen in the inactive state includes at least the display unit 11 and the display unit 21. A control program to be executed on one side is included. In addition, various applications such as a call, mail, a web browser, and an image display are stored.

  Data such as audio data, image data, and text data is stored in the memory 200 in a predetermined file format. Examples of these data include data of photographs taken by the camera module 15, data input by the panel sensors 12 and 22, and data captured from the outside via the communication module 304.

  The memory 200 stores information about images displayed on the display surfaces 11a1 and 21a1. The images displayed on the display surfaces 11a1 and 21a1 include pictures such as icons, buttons, and photographs, and text input in a text area. The information related to the image includes image information and the position where the image is displayed on each of the display surfaces 11a1 and 21a1. Information on images such as icons and buttons includes processing information represented by the images. The processing information includes processing targets such as applications and files and processing contents such as activation and termination.

  The memory 200 stores information related to the first and second touch keys. The information regarding the first and second touch keys includes the key sensors 14 and 24 that detect the input of each touch key, and information on the process associated with each touch key. For example, the first touch key K11 is associated with processing information for displaying the operation item screen on the first display surface 11a1. The second touch key K21 is associated with processing information for displaying the operation item screen on the second display surface 21a1. The first touch key K12 and the second touch key K22 are associated with processing information for displaying a screen for changing setting conditions and a screen of a predetermined application on each display surface 11a1, 21a1. The first touch key K13 and the second touch key K23 are associated with processing information for displaying the screen of the application displayed immediately before on the display surfaces 11a1 and 21a1.

  The CPU 100, based on signals from the key input circuit 303, the panel sensors 12, 22 and the key sensors 14, 24, according to the control program, the camera module 15, the microphone 35, the communication module 304, the liquid crystal panels 11a, 21a, and the speaker 38. And so on. Thereby, CPU100 performs various applications, such as a telephone call and mail.

CPU100 performs the process according to the input by a user as an execution part. Specifically, when each display surface 11a1, 21a1 is touched by a user's finger, the CPU 100 receives a position signal corresponding to the input position from each panel sensor 12,22. The CPU 100 specifies the image displayed at the position signal input position and the processing information represented by the image based on the display information in the memory 200. The CPU 100 reads a processing target application or file from the memory 200 in accordance with the specified processing information, and causes the application to execute the processing content.

  For example, as illustrated in FIG. 4A, when the user touches the mail icon A, the CPU 100 reads out the application A, which is the processing target of the icon A, from the memory 200 and starts it.

  When each key cover 13a, 23a is touched by a user's finger, the CPU 100 receives a detection signal from each key sensor 14, 24 and identifies the key sensor 14, 24 that has output the detection signal. The CPU 100 specifies the touch keys detected by the key sensors 14 and 24 and the processing information associated with the touch keys 14 and 24 based on the display information in the memory 200, and executes the processing according to the processing information.

  For example, when the user touches the first touch key K <b> 11 shown in FIG. 4A, the CPU 100 reads the image data of the operation item screen from the memory 200.

  The CPU 100 outputs a control signal to the video decoder 306 and the backlight drive circuit 305 as a control unit. For example, the CPU 100 controls the backlight drive circuit 305 to turn off the panel backlights 11b and 21b and the key backlights 13b and 23b. On the other hand, the CPU 100 turns on the panel backlights 11b and 21b and controls the video decoder 306 to display images on the display surfaces 11a1 and 21a1. In addition, the CPU 100 turns on the key backlights 13b and 23b. The CPU 100 also controls contrast, brightness, screen size, screen transparency, and the like when displaying images on the display surfaces 11a1 and 21a1.

  For example, the CPU 100 displays a screen based on the application executed by the execution unit on each of the display surfaces 11a1 and 21a1. That is, when the application A is started by the execution unit with the first liquid crystal panel 11a as an output destination, the screen of the application A is displayed on the first display surface 11a1 as shown in FIG. 4B. Further, when image data of the operation item screen is read by the execution unit using the first and second liquid crystal panels 11a and 21a as output destinations, the operation item screen is displayed in the first and second displays as shown in FIG. It is displayed on the surfaces 11a1, 21a1.

  Further, when different application screens are displayed on the display surfaces 11a1 and 21a1, a display form for identifying the active screen and the inactive screen is adopted. It should be noted that the screen based on the different application is different from the application being executed with the first liquid crystal panel 11a as the output destination and the application being executed with the second liquid crystal panel 21a as the output destination. The case where the screen and the screen of the second display surface 21a1 are different is included. Further, even if the applications being executed with the first and second liquid crystal panels 11a and 21a as the output destination are the same, a plurality of processes are executed in parallel for one application, and one process screen is displayed on the first display. The case where the screen of other processing is displayed on the surface 11a1 and displayed on the second display surface 21a1 is also included in the screen based on a different application.

For example, as shown in FIG. 4B, when the first display surface 11a1 is touched by the user, a position signal is output from the first panel sensor 12 to the CPU 100 and displayed on the first display surface 11a1. The screen is determined to be the active screen. As a result, the CPU 100
Displays a linear bar image on one edge of the first screen of the first display surface 11a1. Further, the first key backlight 13b is turned on and the second key backlight 23b is turned off. As a result, the second touch key becomes darker than the first touch key. Therefore, it is displayed that the screen of the first display surface 11a1 is in the active state and the screen of the second display surface 21a1 is in the inactive state.

  On the other hand, as shown in FIG. 5A, when the user touches the second display surface 21a1, the second screen 21a1 displayed on the second display surface 21a1 based on the position signal from the second panel sensor 22 is displayed. The active state is determined. As a result, the CPU 100 displays the bar image as an image indicating the active state on the edge of the second screen, turns on the second key backlight 23b, and turns off the first key backlight 13b. This indicates that the screen of the first display surface 11a1 is in an inactive state and the screen of the second display surface 21a1 is in an active state.

  Note that when the screens based on different applications are not displayed on the first and second display surfaces 11a1 and 21a1, there is no need to define an active screen and an inactive screen, so the CPU 100 displays the active screen and the inactive screen. Display control for identification is not executed. For example, as shown in FIG. 4A, when the screen based on the application is not displayed on either of the first and second display surfaces 11a1 and 21a1, predetermined first touch keys K11, K12, and K13 are displayed. The second touch keys K21, K22, and K23 are turned on. As shown in FIG. 5B, when the screens A1 and A2 based on one application A are displayed on the first and second display surfaces 11a1 and 21a1, predetermined first touch keys K11 and K12 are displayed. , K13 are turned off, and the second touch keys K21, K22, K23 are turned on.

When a touch key in an inactive state is touched, the touch key enters an active state and lights up.

<Processing procedure of the first embodiment>
FIG. 4A shows the operation item screen displayed on the first and second display surfaces 11a1 and 21a1. FIG. 4B is a diagram in which the screen of application A is displayed on the first display surface 11a1 as the active screen, and the screen of application B is displayed on the second display surface 21a1. FIG. 5A is a diagram in which the screen of application A is displayed on the first display surface 11a1, and the screen of application B is displayed on the second display surface 21a1 as an active screen. FIG. 5B is a diagram in which the first screen A1 of the application A is displayed on the first display surface 11a1, and the second screen A2 of the application A is displayed on the second display surface 21a1. FIG. 6 is a flowchart illustrating a processing procedure indicating the state of the screen in accordance with a user operation.

  When the function for controlling the display is set so as to indicate the state of the screen in accordance with the user's operation, the CPU 100 executes a process for controlling the display. In this control process, in the display form for identifying the active screen and the inactive screen, an image indicating the active state is displayed on the active screen, and the touch corresponding to the display surfaces 11a1 and 21a1 displaying the active screen is displayed. The key is turned on, and the touch keys corresponding to the display surfaces 11a1 and 21a1 that display the inactive screen are turned off.

  Whether or not each of the display surfaces 11a1 and 21a1 is operated is monitored in a state where a predetermined screen is displayed on each of the first display surface 11a1 and the second display surface 21a1 (S101).

  When the display surfaces 11a1 and 21a1 are touched (S101: YES), it is determined whether or not the application is being executed with the liquid crystal panels 11a and 21a as output destinations (S102). Here, as shown in FIG. 4A, when the operation item screen is displayed on each of the display surfaces 11a1 and 21a1, the application is not executed (S102: NO). For this reason, since the user does not need to identify the active state and the inactive state, the predetermined second touch keys K21, K22, and K23 are turned on, and the other first touch keys K11, K12, and K13 are turned off. (S103).

  Further, when the icon A is touched by the user on the operation item screen shown in FIG. 4A, the application A indicated by the icon A is activated with the first liquid crystal panel 11a as the output destination, and the screen of the application A is the first display. It is displayed on the surface 11a1. At this time, the operation item screen remains displayed on the second display surface 21a1. In such a state, when each of the display surfaces 11a1 and 21a1 is touched (S101: YES), the application is not executed with the second liquid crystal panel 21a as the output destination (S102: NO). The state where the two touch keys K21, K22, and K23 are turned on and the first touch keys K11, K12, and K13 are turned off is maintained (S103).

  Next, when the screen of the application A is displayed on the first display surface 11a1 and the icon B on the operation item screen is touched on the operation item screen displayed on the second display surface 21a1, the application B is displayed on the second liquid crystal. The panel 21a is activated as an output destination, and the screen of the application B is displayed on the second display surface 21a1 (see FIG. 4B). In such a state, when the display surfaces 11a1 and 21a1 are touched (S101: YES), it is determined that the applications A and B are activated with the liquid crystal panels 11a and 21a as output destinations (S102: YES).

  Next, it is determined whether or not the applications executed by using the liquid crystal panels 11a and 21a as output destinations or the processes of the applications match (S104). Here, since application A and application B do not match, it is determined that the applications are different (S104: YES).
