  By the way, many recent mobile phones have a display unit and a key input unit arranged in separate housings. In this type of mobile phone, as a general operation style, two cases are folded and the key input part is hidden inside (closed state), and both the key input part and the display part are exposed (open state) ).

In addition, there are generally two types of such a two-casing type structure in which the display unit is hidden on the inner side in the closed state and a type in which the display unit is exposed on the outer side.
The former type includes, for example, a type that is folded inward with the surface of the display unit and the surface of the key input unit facing each other. The latter type has, for example, a mechanism that relatively rotates the surface of the display unit and the surface of the key input unit in a substantially parallel state, and in the closed state, the key input unit is placed under the casing of the display unit.

  Next, the operation of the mobile phone 10 having the above-described configuration will be described focusing on the navigation function related to the present invention.

FIG. 5 is a flowchart illustrating the flow of processing related to acquisition of position information and map information.
Steps ST101 to ST103 indicate processing in the control unit 159 of the mobile phone 10, and steps ST201 to ST203 indicate processing in the server device 40.

  First, the control unit 159 causes the GPS receiving unit 151 to receive a signal from the GPS satellite 20, and acquires information related to the received signal (step ST101). Next, the acquired information is transmitted from the communication processing unit 150 to the server device 40 (step ST102).

Information transmitted from the communication processing unit 150 is received by the base station 30 and transmitted to the server device 40 via the communication network.
The server device receives this information as a processing request from the mobile phone 10 (step ST201), and calculates the geographical position of the mobile phone 10 based on the received information. Further, based on the calculated position, the map information around the mobile phone 10 is searched from the database (step ST202). Then, the calculated position information and searched map information are returned from the communication network to the mobile phone 10 via the base station 30 as a processing result in response to the processing request (step ST203).

  The control unit 159 waits for a reply from the server device 40 that responds to the information transmitted in step ST101. When the communication processing unit 150 receives this reply, the control unit 159 acquires position information and map information included in the reply (step ST103).

  FIG. 6 is a flowchart illustrating the flow of processing related to the input of information from the key input unit 154 during the navigation operation.

  The control unit 159 determines whether the operating state of the movable mechanism 103 is an open state or a closed state in the determination result S4 of the open / close determination unit 153 (step ST301).

If it is determined to be in the open state, the control unit 159 associates control information input from the key input unit 154 with the operation keys used for the input, for example, as shown in FIG. Set as shown in (A).
That is, in the navigation display mode, the scroll information for scrolling the map up / down / left / right is associated with the up / down / left / right key of the operation key 115. In addition, mode transition information for instructing mode transition from the navigation display mode to the menu selection mode is associated with the operation key 116.
In the menu selection mode, selection object movement information for moving the selection object up and down on the display screen 104 is associated with the up and down keys of the operation key 115, respectively. Further, selection determination information for instructing determination of the selection result is associated with the operation key 116.

On the other hand, when it is determined as the closed state, the control unit 159 sets the association between the control information input from the key input unit 154 and the operation key as shown in FIG. 7B, for example.
That is, in the navigation display mode, scroll information for scrolling the map up and down is associated with the operation keys 122 and 124, respectively. In this case, the scroll information for scrolling the map to the left and right is not associated with the operation key, and the left and right scroll is invalidated. Further, mode transition information for instructing mode transition is associated with the operation key 123 disposed between the operation keys 122 and 124.
In the menu selection mode, selection target movement information for moving the selection target up and down on the display screen 104 is associated with the operation keys 122 and 124, respectively. In addition, selection determination information for instructing determination of the selection result is associated with the operation key 123.

After setting the above-described association, the control unit 159 inputs a signal generated in the key input unit 154 by an input operation to the operation key as predetermined information according to the association, and performs predetermined processing according to the input information. Is executed (step ST305).
Thereafter, control unit 159 determines whether to end or continue the navigation operation (step ST305), and when the instruction to continue is issued, repeats the processing of steps ST301 to ST304.

  FIG. 8 is a flowchart illustrating an example of the overall processing flow of the navigation operation.

The control unit 159 executes the processing of steps ST101 to ST103 in FIG. 5 and acquires information on the geographical position of the current location and the surrounding map from the server device 40 (step ST401).
Further, the direction detection unit 158 detects the direction and acquires the detection result (step ST402).

  When the position information, the map information, and the direction information are obtained, the control unit 159 generates image data to be displayed on the display screen 104 based on the information, and supplies the image data to the display unit 155 ( Step ST403). As a result, a map image showing the position of the current location and the surrounding area is displayed on the display screen 104 in a direction corresponding to the detection result of the direction detection unit 158.

As can be seen by comparing FIG. 2A and FIG. 3A, since the orientation of the display screen 104 with respect to the user differs by 180 ° between the open state and the closed state, the same image is obtained in these two operating states. When is displayed, the orientation of the image viewed from the user is upside down.
Therefore, for example, the control unit 159 may perform processing such as rotation or arrangement change on the map or symbol image on the display screen 104 in accordance with the determination result of the open / close determination unit 153. Thereby, the orientation of the display image with respect to the user can be maintained in an appropriate state.

  When the control unit 159 displays the image on the display screen 104 as described above and scroll information for instructing image scrolling is input by the key input process (step ST304) in FIG. 6 (step ST404). Depending on this information, the display position of the map on the display screen 104 is changed, and the map is scrolled (step ST405).

  In addition, when the mode transition information instructing the transition from the menu display mode to the menu selection mode is input by the key input process (step ST304) in FIG. 6 (step ST406), the control unit 159 performs the process The mode is shifted to the menu selection mode, and processing contents are selected (step ST407).

In the menu selection mode, the operation key used for the vertical scrolling in the navigation display mode is used for the vertical movement of the selection target on the display screen 104. Further, the operation keys used for shifting from the navigation display mode to the menu selection mode are used for determining the selection result.
When the selection result is determined by an input operation on these operation keys, the control unit 159 returns the processing mode from the menu selection mode to the navigation display mode again.
Thereafter, control unit 159 determines whether to end or continue the navigation operation (step ST408), and when the instruction to continue is issued, repeats the processing of steps ST401 to ST407.

As described above, according to the present embodiment, the movable mechanism 103 in which the association between the information for controlling the flow of processing related to navigation and the operation key for inputting the information is determined by the open / close determination unit 153. It is set according to the operating state.
Therefore, even if the operating state of the movable mechanism changes between the open state and the closed state, the information input to control the flow of processing related to navigation does not change and is used to input that information. Only the operation keys are changed. Therefore, it becomes possible to reduce the difference in operability of information input due to the difference in operating state of the movable mechanism 103, and it is possible to display information on the geographical position and orientation of the current location with a unified operation.
In addition, the correspondence between the input information and the operation key is changed, and the operation flow is common in the two operation states, so that it is not necessary to provide a separate program operation flow for each operation state, and the program is simplified. Can be

Further, according to the present embodiment, the scroll information for scrolling the map image indicating the position and orientation of the current location in the forward and backward directions toward the reference direction A set on the display screen 104 is in an open state. Are associated with the up and down direction keys of the operation key 115, and are associated with the operation keys 122 and 124 in the closed state.
Therefore, the map can be scrolled in a direction in which the image on the display screen 104 moves forward or backward with respect to the traveling direction by a unified operation in both the open state and the closed state.

  In many cases, the information necessary for the user to determine the course is a map of the traveling direction and the opposite direction. Therefore, at the time of heading-up display in which the map is displayed so that the upper direction of the display screen is the user's direction of travel, as described above, the scrolling of the map up and down is unified in both the open state and the closed state. By making it executable, the user can easily obtain necessary information with a favorite operation style, and can enjoy high convenience.

Furthermore, according to the present embodiment, mode transition information for instructing the transition of the processing mode between the navigation display mode for displaying the current position and orientation information and the menu selection mode for selecting the processing content, and The selection determination information for instructing the determination of the selection result in the menu selection mode is associated with the operation key 116 on the operation surface in the open state, and is associated with the operation key 123 on the side surface in the closed state.
Therefore, in either the open state or the closed state, it is possible to change the processing mode and determine the selection result with a unified operation.

Further, according to the present embodiment, the selection information for selecting the processing content in the menu selection mode is associated with the operation key used for inputting scroll information in the navigation display mode. That is, the up and down keys of the operation key 115 in the open state and the operation keys 122 and 124 in the closed state are used for inputting selection information in the menu selection mode.
In this way, by changing the control information associated with the operation key according to the processing mode, one operation key can be used for inputting a plurality of different information, so that the number of operation keys necessary for inputting the control information is reduced. It becomes possible. Even in the closed state where the number of usable operation keys is limited, the operability that is the same as the open state can be maintained.

  The present invention is not limited to the above-described embodiment, and various modifications can be made.

  In the embodiment described above, the operation keys 122 to 124 are arranged on the side surface of the first housing 101. However, the present invention is not limited to this example. For example, these keys are arranged on the side surface of the second housing 102. Alternatively, these keys may be arranged on the surface of the second housing 102.
