The mobile phone 10 has a mobile radio communication function and a mail transmission / reception function. When a call is made using the mobile radio communication function, the mobile phone 10 makes a call to the originating exchange SW via the registered base station BS. In response to the outgoing call, the originating side exchange SW switches the terminating side exchange SW based on the called party number (subscriber number) and location registration information inquired from a subscriber registration server (not shown) provided in the wireless communication network RN. Call. The called-side exchange SW calls the called-side mobile phone 10 (not shown) via the called-side base station BS, and when the called-side side responds to the incoming call, the calling-side exchange SW and the called-side exchange are exchanged. A link with the SW is established and communication becomes possible.

  Mail transmitted from the mobile phone 10 using the mail transmission / reception function is transmitted to a mail server (not shown) on the Internet via a base station BS, an exchange SW, and a gateway server (not shown) provided in the wireless communication network RN. Is done. The mail server is configured to send mail to the mobile phone 10 having the destination mail address through the reverse route.

(2) Configuration of Mobile Phone 10 Next, the configuration of the mobile phone 10 will be described with reference to FIG. In FIG. 2, the CPU 100 controls the operation of each unit according to an event supplied from the operation unit 106 (described later). The characteristic processing operation of the CPU 100 according to the gist of the present invention will be described in detail later.

  The ROM 101 includes a program area and a data area. Various programs executed by the CPU 100 are stored in the program area of the ROM 101. The various programs mentioned here include a main routine, a sub-screen display process, a priority determination process, a display position specifying A process, a sub-screen display position changing process, and a display position specifying B process, which will be described in detail later. In the data area of the ROM 101, in addition to control data referred to by a predetermined program, various screen data forming a standby screen, for example, are stored. The RAM 102 includes a priority order information storage unit 102a and a display position information storage unit 102b in addition to a work area for temporarily storing various register / flag data.

  The priority order information storage unit 102a provided in the RAM 102 stores priority order information representing the priority order of the sub-screens and the corresponding display position according to the determination condition (described later). FIG. 3 is a configuration example of priority order information stored in the priority order information storage unit 102a. In the example shown in this figure, the priority order information is composed of “setting flag”, “decision condition”, “priority order”, and “display position”.

The setting flag is “1” when representing a determination condition selected by a user operation, and “0” otherwise. That is, the setting flag represents the determination condition currently employed. The determination condition includes the type of display content on the main screen and the housing style. The type of display content on the parent screen represents the attribute of display data displayed on the parent screen, and is composed of horizontally written text, vertically written text, images, and others (for example, a web page in which text and images are mixed). .

As shown in FIG. 4, the casing style is a vertical view style (see FIG. 4A) in which the display screen DSP of the display unit 105 is aligned with the casing of the mobile phone 10, and the display screen DSP is carried. This represents a horizontal view style (see FIG. 4B) that is rotated 90 degrees with respect to the case of the telephone 10 and turned sideways.

  The priority order represents a display priority given to each display form (horizontal text, vertical text, image, etc., vertical view style and horizontal view style) constituting the determination condition. In addition, the display positions A to D of the sub-screens are associated with the priorities of these items. The display positions A to D of the sub-screen are, for example, the positional relationship shown in FIG. 5A when the display screen DSP is in the vertical view style, and FIG. 5 when the display screen DSP is in the horizontal view style. The positional relationships shown in FIG.

  Such priority information is referred to in a priority determination process (described later) executed by the CPU 100. In addition, the priority order information of the configuration illustrated in FIG. 3 gives an example in which the determination condition is divided into two types, that is, the type of content displayed on the parent screen and the housing style, in order to simplify the description. Not limited to, for example, in the case of horizontal text and vertical view style, or in the case of horizontal text and horizontal view style, a determination condition that combines two different items is set, and priority and display position can be assigned to this. I do not care.

  The display position information storage unit 102b provided in the RAM 102 stores display position information indicating the position where the child screen is displayed on the parent screen. The display position information includes first display position information indicating the display position of the child screen in response to the child screen display instruction operation, and first display position of the child screen to be newly displayed in response to the child screen display position change instruction operation. 2 display position information. Hereinafter, the configuration of the first and second display position information will be described with reference to FIGS.

FIG. 6 is an example of first display position information stored in the display position storage unit 102b, and includes “setting flag”, “operation status”, and “display position”. The setting flag is set to “1” when representing an operation state selected by a user operation, and is set to “0” otherwise. That is, the setting flag represents the operation status currently employed. The operation status includes the operation time and the number of operations of the sub-screen display instruction operation.

The display position represents the display position of the child screen associated with each item of the operation status (the operation time of less than 1 second, the operation time of 1 second or more, the number of operations of 1 time, and the number of operations of 2 or more). For example, in the example illustrated in FIG. 6, when the currently used operation status is “number of operations”, when a single sub-screen display instruction operation is performed, the display position with the priority “1” is designated. Is done. Such first display position information is referred to in a display position specifying A process (described later) executed by the CPU 100.

FIG. 7 is an example of the second display position information stored in the display position storage unit 102b, and similarly to the first display position information described above, “setting flag”, “operation status”, and “display position”. Consists of. The setting flag is a flag that is set to “1” when representing an operation state selected by a user operation, and “0” otherwise, and represents an operation state that is currently employed. The operation status includes the operation time and the number of operations of the sub-screen display instruction changing operation.

The display position represents the display position of the child screen associated with each item of the operation status (the operation time of less than 1 second, the operation time of 1 second or more, the number of operations of 1 time, and the number of operations of 2 or more). For example, in the example illustrated in FIG. 7, when the operation state currently employed is “number of operations” and the sub-screen display instruction change operation is performed two or more times, the display position whose priority is lower by two ranks. Is specified. Such second display position information is referred to in a display position specifying B process (described later) executed by the CPU 100.

Now, the configuration of the mobile phone 10 will be described with reference to FIG. 2 again. In FIG. 2, the wireless communication transmitting / receiving unit 103 exchanges data with the base station BS via the antenna ANT1 under the control of the CPU 100 during data communication, and receives and demodulates the voice data received and demodulated through the antenna ANT1 during the voice call to the CPU 100. On the other hand, the transmission signal obtained by modulating the audio data supplied from the CPU 100 is amplified at high frequency and transmitted from the antenna ANT1.

  The audio signal processing unit 104 includes a speaker SP and a microphone MIC. The audio data supplied from the CPU 100 is D / A converted into an audio signal to generate sound from the speaker SP, or an audio signal output from the microphone MIC is converted into audio data. A / D-converted and supplied to the CPU 100. The display unit 105 includes a color liquid crystal panel and a display driver, and displays a parent screen and a child screen on the display screen DSP in various display modes under the control of the CPU 100.

The operation unit 106 includes various operation keys such as a power switch for power on / off, an off-hook / on-hook switch operated at the start / end of a call, and a character input switch that also serves as a dial switch. There are various operation buttons and the like for performing a sub-screen display position change instruction operation, and an event corresponding to the operation of these keys and buttons is generated and output to the CPU 100. Note that the setting operation, the sub-screen display instruction operation, and the sub-screen display position change instruction operation are intended later. The RTC 107 generates a real time clock used for timekeeping and timer interruption. The casing style detection unit 108 detects the “vertical view style” or “horizontal view style” illustrated in FIG. 4.

B. Action
Next, the operation of the mobile phone 10 having the above configuration will be described. Hereinafter, the operation of the “main routine” executed by the CPU 100 of the mobile phone 10 will be described with reference to FIGS. 8 to 9, and then the “sub-screen display process” called from the main routine with reference to FIG. 10. The operation will be described. The operations of “priority determination processing” and “display position specifying A processing” called from the sub-screen display processing will be described with reference to FIGS. Furthermore, after describing the operation of the “sub-screen display position changing process” called from the main routine with reference to FIG. 13, the “display position specifying B” called from the sub-screen display position changing process with reference to FIG. The operation of “processing” will be described.

(1) Operation of Main Routine FIGS. 8 to 9 are flowcharts showing the operation of the main routine executed by the CPU 100. FIG. When the mobile phone 10 is powered on by the user's power-on operation, the CPU 100 proceeds to step SA1 shown in FIG. 8 and executes the location registration control sequence to perform location registration on the network side. Execute standby processing to enter the state.

  Subsequently, in steps SA2 to SA4 and steps SA5 to SA7 shown in FIG. 9, “setting operation”, “sub-screen display instruction operation”, “sub-screen display position change instruction operation”, “incoming call detection”, “power supply” It is determined whether there is an event of “off operation” and “other operation”. If these events do not occur, the determination results in steps SA2 to SA7 are “NO”, and the apparatus stands by in a standby state. On the other hand, when any of the above events occurs in the standby state, processing corresponding to the generated event is executed. Hereinafter, the operation for each event will be described.

a. When the setting operation is performed In this case, the determination result in step SA2 is “YES”, and the process proceeds to step SA8 to execute the setting process. In the setting process, the priority information (see FIG. 3) is newly registered in the priority information storage unit 102a of the RAM 102 or the contents of the registered priority information are edited in accordance with the user's setting operation. In the setting process, first and second display position information (see FIGS. 6 and 7) is newly registered in the display position information storage unit 102b of the RAM 102, and contents are edited. When the setting process in step SA8 is completed, the CPU 100 returns the process to step SA2 and returns to the standby state.

b. When a sub-screen display instruction operation is performed
When a sub-screen display instruction operation for instructing display of the sub-screen is performed, the determination result in step SA3 is “YES”, and the process proceeds to step SA9 to execute a sub-screen display process. In the sub-screen display process, as described later, after detecting the operation status (operation time and the number of operations) of the sub-screen display instruction operation, the priority order for displaying the sub-screen in the current display form is determined, Among the detected operation situations, the display position of the sub-screen that is associated with the currently adopted operation situation and specified by the priority order is specified. Then, the sub-screen is displayed at the display position designated by the specified priority among the priorities when displaying the sub-screen in the current display form. When such a small screen display process is completed, the process returns to step SA2 to return to the standby state.

c. When a sub-screen display position change instruction operation is performed
When a sub-screen display position change instruction operation for instructing a change of the sub-screen display position is performed, the determination result in step SA4 is “YES”, the process proceeds to step SA10, and a sub-screen display position change process is executed. In the sub-screen display position change process, as will be described later, after detecting the operation status (operation time and the number of operations) of the sub-screen display position change instruction operation, priority information stored in the priority information storage unit 102a of the RAM 102 The priority assigned to the display form corresponding to the determination condition currently employed is read out from the above, and the priority (current priority) of the currently displayed sub-screen is obtained.

Then, among the detected operation situations (operation time and number of operations), the display position of the child screen that is associated with the currently adopted operation situation and is designated with a priority lower than the current priority by a predetermined rank, The second display position information stored in the display position information storage unit 102b of the RAM 102 is read out and specified, and the sub-screen is displayed by changing to the display position specified by the specified priority. When the child screen display position changing process is completed, the process returns to step SA2 to return to the standby state.

d. When an incoming call is detected
When an incoming call is detected, the determination result in step SA5 shown in FIG. 9 is “YES”, and the process proceeds to step SA11 to execute incoming call processing. In the incoming call processing, incoming call notification is performed, and when an off-hook operation is performed during this incoming call notification, a line is connected to the calling party to start a call, and the line is disconnected according to the on-hook operation. When the incoming call processing is completed, the process returns to step SA2 to return to the standby state.

e. When the power is turned off
In this case, the determination result in step SA6 is “YES”, the process proceeds to step SA12, the power-off process is executed, and the process is completed.

f. When other operations are performed
When other operations other than those described above are performed, the determination result of step SA7 is “YES”, and the process proceeds to step SA13 to execute other processes. Other processing refers to processing such as mail creation and mail transmission. Then, after the other processes are executed, the process returns to step SA2 to return to the standby state.

(2) Sub-screen display processing operation
FIG. 10 is a flowchart showing the operation of the small screen display process. When this process is executed via step SA9 (see FIG. 8) of the main routine described above, the CPU 100 proceeds to step SB1 shown in FIG. 10 and detects the operation status of the sub-screen display instruction operation. Specifically, the operation time (pressing time) and the number of operations (pressing number) of the operation button pressed as the sub-screen display instruction operation are detected. Next, in step SB2, the operation time and the number of operations detected in step SB1 are temporarily stored in the work area of the RAM 102.

  Subsequently, in step SB3, priority order determination processing is executed. In the priority order determination process, as will be described later, a display mode (horizontal text, horizontal text, etc.) corresponding to the determination condition currently employed from the priority information stored in the priority information storage unit 102a (see FIG. 3) of the RAM 102. The priority assigned to the vertical writing text, the image, the other, any of the vertical view style and the horizontal view style) is read, and the priority for displaying the sub-screen in the current display form is determined.

  Next, in step SB4, display position specifying A processing is executed. In the display position specifying A process, as will be described later, among the operation situations (operation time and the number of operations) detected in step SB1, a child that is associated with the currently adopted operation situation and designated by priority. The display position of the screen is read out from the first display position information stored in the display position information storage unit 102b of the RAM 102 and specified.

In step SB5, the display position specified in the display position specifying process A in step SB4, that is, the priority order in displaying the child screen in the current display mode determined in the priority order determining process in step SB3. Of these, the sub-screen is displayed at the display position specified in the priority order specified by the display position specifying A process in step SB4.

As described above, in the sub-screen display processing, after the operation status (operation time and the number of operations) of the sub-screen display instruction operation is detected, it is currently adopted from the priority information stored in the priority information storage unit 102a of the RAM 102. The priority assigned to the display mode corresponding to the determined determination condition is read, and the priority for displaying the sub-screen in the current display mode is determined. Then, among the detected operation situations, a first sub-screen display position stored in the display position information storage unit 102b of the RAM 102 is associated with the operation situation currently employed and specified in the priority order. When the display position information is read out and specified, the sub-screen is displayed at the display position specified by the specified priority among the priorities for displaying the sub-screen in the current display form.

Specifically, for example, when the case style is currently adopted as the determination condition and the operation time is currently adopted as the operation status, the display screen DSP displays the main screen in the vertical view style. If a small-screen display instruction operation with an operation time of less than 1 second is performed, priority order 1 (position A), priority order 2 (position C), priority order 3 (position D), and priority assigned to the vertical view style are assigned. A child screen is displayed on the parent screen at position A (see FIG. 5A), which is the display position of priority “1” among the ranks 4 (position B). In this way, for example, when displaying the received mail text on the child screen while displaying the map data or the like on the parent screen, the position A that does not obstruct the display content of the parent screen as much as possible. (See FIG. 5A) The child screen can be displayed by a one-touch operation.

(3) Priority determination processing operation
Next, the operation of the priority order determination process will be described with reference to FIG. When this process is executed through step SB3 (see FIG. 10) of the above-described small screen display process, the CPU 100 proceeds to step SC1 shown in FIG. 11 and is stored in the priority order information storage unit 102a of the RAM 102. The determination condition with the setting flag “1”, that is, the determination condition currently employed is read from the priority order information (see FIG. 3).

In step SC2, it is determined whether or not the determination condition read in step SC1 is “type of display content of parent screen”. If the read determination condition is “type of display content of parent screen”, the determination result is “YES”, and step SC3 and subsequent steps are executed. On the other hand, if the read determination condition is “housing style”, the determination result in step SC2 is “NO”, and step SC12 and subsequent steps are executed. Hereinafter, the description of the operation will be divided into a case where the determination condition selected by the user is “type of display content of parent screen” and a case of “housing style”.

<When the decision condition is "Type of contents displayed on the main screen">
In this case, the process proceeds to step SC3, and the type of display content on the parent screen is detected. In steps SC4 to SC6, it is determined whether the type of the detected display content is “horizontal writing text”, “vertical writing text”, “image”, or “others”.

If the type of display content detected is “horizontal text”, the determination result in step SC4 is “YES”, the process proceeds to step SC7, and the priority information stored in the priority information storage unit 102a of the RAM 102 is selected. After the priority assigned to “horizontal text” is read, the process proceeds to step SC8, where the read priority is determined and the process is terminated.

If the type of the detected display content is “vertical text”, the determination result in step SC5 is “YES”, the process proceeds to step SC9, and the priority information stored in the priority information storage unit 102a of the RAM 102 is included. After reading the priority assigned to “vertical text”, the process proceeds to step SC8, where the read priority is determined and the process is terminated.

If the type of the detected display content is “image”, the determination result in step SC6 is “YES”, the process proceeds to step SC10, and the priority information stored in the priority information storage unit 102a of the RAM 102 is “ After reading the priority assigned to “image”, the process proceeds to step SC8, where the read priority is determined and the process is terminated.

If the type of the detected display content is “other”, the determination results in steps SC4 to SC6 are all “NO”, the process proceeds to step SC11, and the priority stored in the priority information storage unit 102a of the RAM 102 is displayed. After reading the priority assigned to “others” from the rank information, the process proceeds to step SC8, where the read priority is determined and the process is terminated.

<When the decision condition is "Case style">
In this case, the process proceeds to step SC12, and the current casing style ("vertical view style" or "horizontal view style") is detected based on the detection output of the casing style detection unit 108. In step SC13, it is determined whether or not the detected casing style is the “vertical view style”. If the housing style is “vertical view style”, the determination result is “YES”, and the process proceeds to step SC14 to assign to “vertical view style” from the priority information stored in the priority information storage unit 102a of the RAM 102. After the read priority order is read, the process proceeds to step SC8, where the read priority order is determined and the process is terminated.

  On the other hand, if the housing style is “horizontal view style”, the determination result in step SC13 is “NO”, the process proceeds to step SC15, and the priority order information stored in the priority order information storage unit 102a of the RAM 102 is selected. After reading the priority assigned to the “horizontal view style” from step S8, the process proceeds to step SC8, where the read priority is determined and the process is terminated.

  As described above, in the priority order determination process, the display format (horizontal text, vertical text, image) corresponding to the determination condition currently employed from the priority information stored in the priority information storage unit 102a of the RAM 102 is used. In addition, the priority assigned to any one of the vertical view style and the horizontal view style) is read, and the priority for displaying the sub-screen in the current display form is determined.

(4) Display position identification A processing operation
Next, the operation of the display position specifying A process will be described with reference to FIG. When this process is executed through the above-described sub-screen display process step SB4 (see FIG. 10), the CPU 100 proceeds to step SD1 shown in FIG. 12 and is stored in the display position information storage unit 102b of the RAM 102. The operation status with the setting flag “1”, that is, the operation status currently employed is read out from the first display position information (see FIG. 6).

Subsequently, in step SD2, it is determined whether or not the operation status read in step SD1 is “operation time”. If the read operation status is “operation time”, the determination result is “YES”, and step SD3 and subsequent steps are executed. On the other hand, if the read operation status is “number of operations”, the determination result in step SD2 is “NO”, and step SD7 and subsequent steps are executed. In the following, the description of the operation is divided into a case where the operation state selected by the user is “operation time” and a case where “the number of operations”.

<When the operation status is "Operation time">
In this case, the process proceeds to step SD3, and the operation time temporarily stored in the work area of the RAM 102 in step SB2 (see FIG. 10) of the small-screen display process described above is read. In step SD4, it is determined whether or not the read operation time is “less than 1 second”. If the operation time is "less than 1 second", the determination result is "YES", and the process proceeds to step SD5. In step SD5, the display position of the priority “1” associated with the operation time “less than 1 second” is selected from the first display position information stored in the display position information storage unit 102b of the RAM 102. Reading, thereby specifying the display position of the sub-screen and finishing this processing.

  On the other hand, if the operation time is not “less than 1 second”, the determination result in step SD4 is “NO”, and the process proceeds to step SD6. In step SD6, the display position of the priority order “2” associated with the operation time “1 second or longer” is selected from the first display position information stored in the display position information storage unit 102b of the RAM 102. Reading, thereby specifying the display position of the sub-screen and finishing this processing.

<When the operation status is "Number of operations">
In this case, the process proceeds to step SD7, and the number of operations temporarily stored in the work area of the RAM 102 in step SB2 (see FIG. 10) of the small-screen display process described above is read. In step SD8, it is determined whether or not the read operation count is “1”. If the number of operations is “1”, the determination result is “YES”, and the flow proceeds to step SD9. In step SD9, the display position with the priority “1” associated with the number of operations “1” is read from the first display position information stored in the display position information storage unit 102b of the RAM 102. Thus, the display position of the small screen is specified, and this processing is finished.

  On the other hand, if the number of operations is not “one”, the determination result in step SD8 is “NO”, and the process proceeds to step SD10. In step SD10, the display position of the priority order “2” associated with the number of operations “two or more” is selected from the first display position information stored in the display position information storage unit 102b of the RAM 102. Reading, thereby specifying the display position of the sub-screen and finishing this processing.

  As described above, in the display position specifying A process, the operation status (operation time and the number of operations) of the sub-screen display instruction operation detected in step SB1 of the sub-screen display process is associated with the currently used operation status. The display position of the small screen specified by the priority order is read out from the first display position information stored in the display position information storage unit 102b of the RAM 102 and specified.

(5) Sub-screen display position change processing operation
FIG. 13 is a flowchart showing the operation of the sub-screen display position changing process. When this process is executed via step SA10 (see FIG. 8) of the main routine described above, the CPU 100 proceeds to step SE1 shown in FIG. 13 and detects the operation status of the sub-screen display position change instruction operation. . Specifically, the operation time (pressing time) and the number of operations (number of pressings) of the operation button pressed as the sub-screen display position change instruction operation are detected. Next, in step SE2, the operation time and the number of operations detected in step SE1 are temporarily stored in the work area of the RAM 102.

  Subsequently, in step SE3, priority order determination processing is executed. As described above, in the priority order determination process, a display form (horizontal text, vertical text) corresponding to the determination condition currently employed from the priority information stored in the priority information storage unit 102a (see FIG. 3) of the RAM 102 is used. The priority assigned to the written text, the image, the other, any of the vertical view style and the horizontal view style) is read out, and the priority in displaying the sub-screen in the current display form is determined.

  Next, in step SE4, display position specifying B processing is executed. In the display position specifying B process, as will be described later, first, the priority (current priority) assigned to the display position of the currently displayed sub-screen is detected, and then the operation status detected in step SE1 ( The display position information storage unit 102b of the RAM 102 indicates the display position of the sub-screen that is associated with the operation state currently employed in the operation time and the number of operations) and is designated with a priority lower than the current priority by a predetermined rank. The second display position information stored in the information is read out and specified.

In step SE5, the priority order specified by the display position specifying B process in step SE4 among the priorities for displaying the sub-screen in the current display mode determined in the priority order determining process in step SE3. The sub-screen is changed and displayed at the sub-screen display position specified by.

As described above, in the sub-screen display position change process, first, the operation status (operation time and the number of operations) of the sub-screen display position change instruction operation is detected. Thereafter, the priority assigned to the display mode corresponding to the currently adopted determination condition is read from the priority level information stored in the priority level information storage unit 102a of the RAM 102, and the child screen is displayed in the current display mode. The priority order for display is determined, and thereby the priority order (current priority order) assigned to the display position of the currently displayed sub-screen is obtained. Then, among the detected operation situations (operation time and number of operations), the display position of the child screen that is associated with the currently adopted operation situation and is designated with a priority lower than the current priority by a predetermined rank, The second display position information stored in the display position information storage unit 102b of the RAM 102 is read out and specified, and the sub-screen is displayed by changing to the display position specified by the specified priority.

Specifically, for example, when the case style is currently adopted as the determination condition and the number of operations is currently adopted as the operation status, the display screen DSP displays the parent screen in the horizontal view style, and the child screen Is displayed at position B (see FIG. 5B), when a sub-screen display position change instruction operation is performed twice or more times, priority 1 assigned to the horizontal view style is assigned. (Position B), Priority 2 (Position A), Priority 3 (Position C), and Priority 4 (Position D) Display position of Priority 3 below the current priority 1 (Position B) Change to C to display the sub-screen.

(6) Display position specifying B processing operation
Next, the operation of the display position specifying B process will be described with reference to FIG. When this process is executed through step SE4 (see FIG. 13) of the small-screen display position changing process described above, the CPU 100 advances the process to step SF1 shown in FIG. In step SF1, the priority assigned to the display position of the currently displayed sub-screen based on the priority when the sub-screen is displayed in the current display mode determined in the above-described priority determination process. Is detected as the current priority.

Next, in step SF2, the operation state with the setting flag “1” from the second display position information (see FIG. 7) stored in the display position information storage unit 102b of the RAM 102, that is, the operation state currently employed. Is read. Subsequently, in step SF3, it is determined whether or not the operation status read in step SF2 is “operation time”. If the read operation status is “operation time”, the determination result is “YES”, and step SF4 and subsequent steps are executed. On the other hand, if the read operation status is “number of operations”, the determination result in step SF3 is “NO”, and step SF8 and subsequent steps are executed. In the following, the description of the operation is divided into a case where the operation state selected by the user is “operation time” and a case where “the number of operations”.

<When the operation status is "Operation time">
In this case, the process proceeds to step SF4, and the operation time temporarily stored in the work area of the RAM 102 in step SE2 (see FIG. 13) of the above-described sub-screen display position changing process is read. In step SF5, it is determined whether or not the read operation time is “less than 1 second”. If the operation time is "less than 1 second", the determination result is "YES", and the process proceeds to step SF6. In step SF6, the display position associated with the operation time “less than 1 second” is read from the second display position information stored in the display position information storage unit 102b of the RAM 102, and the current priority order is thereby read. The display position of the priority one rank lower than is specified as the display position of the sub-screen that is changed in response to the sub-screen display position change instruction operation, and this processing is completed.

  On the other hand, if the operation time is not “less than 1 second”, the determination result in step SF5 is “NO”, and the process proceeds to step SF7. In step SF7, the display position associated with the operation time “one second or longer” is read from the second display position information stored in the display position information storage unit 102b of the RAM 102, and the current priority order is thereby read. The display position of the priority order two ranks below is specified as the display position of the sub-screen that is changed according to the sub-screen display position change instruction operation, and this processing is completed.

<When the operation status is "Number of operations">
In this case, the process proceeds to step SF8, and the number of operations temporarily stored in the work area of the RAM 102 in step SE2 (see FIG. 13) of the above-described sub-screen display position changing process is read. In step SF9, it is determined whether or not the read operation count is “one”. If the number of operations is “1”, the determination result is “YES”, and the process proceeds to Step SF10. In step SF10, the display position associated with the number of operations “1” is read out from the second display position information stored in the display position information storage unit 102b of the RAM 102, and from this, the current priority is determined. The display position of the priority order one rank lower is specified as the display position of the sub-screen that is changed according to the sub-screen display position change instruction operation, and this processing ends.

  On the other hand, if the number of operations is not “one”, the determination result in step SF9 is “NO”, and the process proceeds to step SF11. In step SF11, the display position associated with the number of operations “two or more” is read from the second display position information stored in the display position information storage unit 102b of the RAM 102, and the current priority order is thereby read. The display position of the priority order two ranks below is specified as the display position of the sub-screen that is changed according to the sub-screen display position change instruction operation, and this processing is completed.

In this way, in the display position specifying B process, the priority (current priority) assigned to the display position of the currently displayed child screen is detected, and then detected in step SE1 of the child screen display position changing process. The sub screen display position change instruction operation status (operation time and number of operations) is associated with the currently used operation status, and the sub screen is designated with a priority lower than the current priority by a predetermined rank. The display position is read out from the second display position information stored in the display position information storage unit 102b of the RAM 102 and specified.

As described above, in this embodiment, when a small-screen display instruction operation is performed, the operation status (operation time and number of operations) is detected and then stored in the priority information storage unit 102a of the RAM 102. The priority assigned to the display mode corresponding to the determination condition currently employed is read from the stored priority order information, and the priority for displaying the sub-screen in the current display mode is determined. Then, among the detected operation situations, a first sub-screen display position stored in the display position information storage unit 102b of the RAM 102 is associated with the operation situation currently employed and specified in the priority order. When the display position information is read out and specified, the child screen is displayed at the display position specified by the specified priority among the priorities for displaying the child screen in the current display form. Can be controlled easily and appropriately.

In this embodiment, when a small-screen display position change instruction operation is performed, the operation status (operation time and operation count) is detected and stored in the priority information storage unit 102a of the RAM 102. The priority assigned to the display format corresponding to the currently adopted determination condition is read out from the priority order information to be determined, and the priority order for displaying the sub-screen in the current display format is determined. The priority order (current priority order) assigned to the displayed position of the sub-screen is obtained. Then, among the detected operation situations (operation time and number of operations), the display position of the child screen that is associated with the currently adopted operation situation and is designated with a priority lower than the current priority by a predetermined rank, Since the second display position information stored in the display position information storage unit 102b of the RAM 102 is read out and specified, the display screen is changed to the display position specified by the specified priority order, and the child screen is displayed. The display position of the screen can be easily and appropriately controlled.
