It is the figure seen from (back side). As described above, in the open style in which the housings 21 and 22 are completely opened, the display direction of the main display unit 7 is the α direction with the hinge portion down as shown in FIG. As shown in FIG. 2C, the display direction of the display unit 8 is changed to the α direction with the hinge unit direction down, and the display direction is changed.

FIG. 4 illustrates display control when priority is given to the open sensor 15 and display control when priority is given to the close sensor 14 depending on whether or not a specific application such as a camera function, a television function, or a video playback function is operating. It is a figure for doing.
In the figure, “closed” in a circle indicates a case of “ON” in which complete close is detected by the close sensor 14, and “open” indicates “ON” in which full open is detected by the open sensor 15. The case between “closed” and “open” indicates a state in which both the casings 21 and 22 are partially opened, and the close sensor 14 and the open sensor 15 are both “OFF”. .

  FIG. 4A shows display control when the open sensor 15 is prioritized, and is executed during the operation of the specific application. That is, during the operation of a specific application such as a camera function, a TV function, a video playback function, etc., the two casings 21 and 22 are opened halfway and the ends of both casings 21 and 22 face down. Display control that inverts the top and bottom during the opening from the state where the fully closed (closed) is detected until the fully open (open) is detected. The display direction of the sub display unit 8 is maintained in the β direction without performing the above, and when it is fully opened, the display direction is inverted up and down and changed to the α direction. On the other hand, when it starts to close from the fully open state, the display direction of the sub-display unit 8 is reversed up and down at that time to change to the β direction. In the case of priority on the open sensor, display control for inverting the display direction of the sub display unit 8 is not performed even if the detection signal of the close sensor 14 changes.

  FIG. 4B shows display control when the close sensor 14 is prioritized, and is executed during the non-operation of the specific application described above. That is, when opening is started from the completely closed state, the display direction of the sub-display unit 8 is reversed up and down at that time to change to the α direction. On the other hand, the α direction is maintained during the closing from the fully open state to the fully closed state, and when the fully closed state, the display direction is reversed up and down to change to the β direction. Yes. In the case of close sensor priority, display control for inverting the display direction of the sub display unit 8 is not performed even if the detection signal of the open sensor 15 changes.

  Next, the operation concept of the mobile phone device in the first embodiment will be described with reference to the flowchart shown in FIG. Here, each function described in this flowchart is stored in the form of a readable program code, and operations according to the program code are sequentially executed. In addition, the operation according to the above-described program code transmitted via the transmission medium can be sequentially executed. This is the same in other embodiments described later. In addition to the recording medium, the program / data supplied from the outside via the transmission medium can be used to execute operations specific to this embodiment. FIG. 5 is a flowchart showing an outline of the operation of the characteristic part of the present embodiment in the entire operation of the mobile phone device. When the flow of FIG. Return to).

FIG. 5 is a flowchart showing the display control process that is started when there is a change in the detection signal from the open / close sensor (close sensor 14 or open sensor 15).
First, the CPU 1 determines whether or not a specific application such as a camera function, a television function, or a video playback function is in operation (step A1). Here, if there is a change in the detection signal (ON to OFF or OFF to ON) of the open / close sensor, if the above-mentioned specific application is operating (YES in Step A1), display control giving priority to the open sensor 15 However, if the specific application is not operating (NO in step A1), display control giving priority to the close sensor 14 is performed (steps A6 to A8).

  That is, in the state where the data is displayed by the operation of the specific application, display control giving priority to the open sensor 15 is executed. First, it is checked whether the detection signal of the open / close sensor has changed in the open sensor 15 (step A2). If the detection signal of the close sensor 14 has changed during the operation of the specific application (step A2). NO), the display control for reversing the display direction of the sub-display unit 8 is not performed, and the flow is exited. On the other hand, if there is a change in the detection signal of the open sensor 15 (YES in step A2), whether the detection signal has changed from “OFF” to “ON”, that is, completely opened by a change in the opening direction. It is checked whether it has become a full open style (step A3).

  If the open style is selected (YES in step A3), the display direction of the sub display unit 8 is changed from the β direction to the α direction at that time (step A4). Accordingly, the sub display unit 8 is changed from a display in which the direction of the hinge unit 23 is up to a display in which the direction of the hinge unit 23 is down. That is, the display with the direction of the hinge portion 23 up is maintained until the open style is changed from the closed style to the display with the direction of the hinge portion 23 down when the open style is reached. In the open style, the standby screen is displayed on the main display unit 7, but the main display unit 7 is also displayed with the direction of the hinge unit 23 facing down. Further, when the detection signal of the open sensor 15 changes from “ON” to “OFF”, that is, when it starts to close from the open style state due to a change in the closing direction (NO in step A3), at that time The display direction of the sub display unit 8 is changed from the α direction to the β direction (step A5).

  On the other hand, when display control giving priority to the close sensor 14 is executed, first, it is checked whether the change in the detection signal of the open / close sensor is the close sensor 14 (step A6), and the specific application is not operating. If there is a change in the detection signal of the open sensor 15 (NO in step A6), the display control for reversing the display direction of the sub-display unit 8 is not performed, and the process leaves this flow. On the other hand, if there is a change in the detection signal of the close sensor 14 (YES in step A6), whether the detection signal has changed from “OFF” to “ON”, that is, completely closed by a change in the closing direction. It is checked whether the closed style has been reached (step A7). If the closed style is selected (YES in step A7), the display direction of the sub display unit 8 is changed from the α direction to the β direction at that time (step A5). Further, when opening from the closed style is started due to a change in the opening direction (NO in step A7), the display direction of the sub display unit 8 is changed from the β direction to the α direction at that time (step A8).

  As described above, in the first embodiment, the CPU 1 refers to the detection result of the open sensor 15 and the determination result of whether or not the specific application is operating. , 22 can be maintained from the closed state to the fully opened open style, and on the contrary, the display content can be reversed immediately when the closed style starts from the open style state. Therefore, it is possible to use the housings 21 and 22 with the housings 21 and 22 partially opened. That is, during the operation of a specific application such as a camera function, a TV function, a video playback function, etc., a vertical stand in which both casings 21 and 22 are set up on a desk surface with both casings 21 and 22 opened halfway. In such a vertical stand, it is possible to display in the correct orientation, and conversely, when it starts to close from the open style, it can be used as it is folded, Although it may be used in the state of a vertical stand, in such a way of use, the display direction in the open style is reversed up and down, so that the correct orientation is displayed immediately.

  If the specific application is not in operation, the display direction is immediately moved up and down as soon as it starts to open from the closed style state, as in the past, without considering the case where both the casings 21 and 22 are opened halfway. Conversely, the open style state can be maintained during the closing from the open style to the closed style, and the top and bottom can be reversed when the closed style is reached.

  Note that the first embodiment described above is not limited to the case where the two casings 21 and 22 are half-opened with the casings 21 and 22 partially opened, and the casings 21 and 22 are used in a vertical stand that stands on a desk surface. As shown in FIG. 6, one side surface portion of both housings 21 and 22 in a half-open state in which both housings 21 and 22 are opened halfway, that is, one side surface portion located on the side orthogonal to the hinge portion 23 is used as a desk surface. It may be a case where it is used with a horizontal stand placed on the. Thus, when used in a horizontal stand, side sensors (contact sensors) 16 are provided on the same side surface of both housings 21 and 22, respectively. The display of the sub display unit 8 so that the display is made with the side opposite to the side (contact surface) of the housing in contact with the desk surface, etc., when it is detected that it is placed on the surface. The direction may be changed to the γ direction in the figure. In the drawing, the black circles conceptually show the side sensor 16 and are not provided on the side portions on the same side of the two casings 21, 22, but at least one side portion of the two casings 21, 22. It may be just provided.

  In addition, when the style is changed from complete close to full open, the contents of the sub display unit 8 may be transferred to the main display unit 7 to be switched and displayed. Here, when the style is changed from complete close to full open, the same content may be displayed on the main display unit 7 without deleting the content of the sub display unit 8. Further, when the style is changed from full open to complete close, the contents of the main display unit 7 may be transferred to the sub display unit 8 to be switched and displayed.

  In the first embodiment described above, the close sensor 14 constituting the open / close sensor is configured by a micro sensor, and an ON signal is output while a complete close is detected. If not operating, the close sensor 14 may be detected using a magnetic sensor similar to the conventional one. That is, a Hall element is provided on the front end side of one housing, a magnet is provided on the front end side of the other housing, and close detection is performed by the strength of magnetic force according to the opening / closing state of both housings. Good.

(Example 2)
A second embodiment of the present invention will be described below with reference to FIGS.
In the first embodiment described above, the display direction is reversed on the assumption that the folding cellular phone device is used in a vertical stand, a horizontal stand, etc., but this second embodiment In this case, a predetermined process is executed when the folding cellular phone device is used in the form of a stand.
Here, the same or the same names in both embodiments are denoted by the same reference numerals, the description thereof will be omitted, and the following description will focus on the features of the second embodiment. .

  FIG. 7 shows a foldable mobile phone device that is used in a vertically placed stand that stands on a desk surface with the ends of the casings 21 and 22 facing downward with the casings 21 and 22 opened halfway. It is the figure which showed the case. Side sensors (contact sensors) 17 are respectively provided at end portions (side portions located on the opposite side of the hinge portion 23) of both the casings 21 and 22. In the drawing, the black circles conceptually indicate the side sensors 17. When the side sensors 17 detect that the side sensors 17 are placed on a desk surface or the like, the CPU 1 detects the close sensor 14 and the open sensor 15. Referring to the detection result from, it is determined that the stand is in a vertical stand state, and an application dedicated to the vertical stand (for example, a specific application such as a camera function, a TV function, or a video playback function) is started. . The side sensors 17 of both housings 21 and 22 output an ON signal while detecting that the ends of both housings 21 and 22 are in contact with the desk surface, and otherwise. An OFF signal is output.

  FIG. 8 is a flowchart showing processing that is started when the detection signals from the side sensors 17 of both the casings 21 and 22 change substantially simultaneously. First, the CPU 1 checks whether the change is from “OFF” to “ON” based on the detection signals from the side sensors 17 of both the casings 21 and 22 (step B1), and from “OFF” to “ON”. Is ON (YES in step B1), the detection signals from the close sensor 14 and the open sensor 15 are both “OFF”, that is, in a half-open state in which both the casings 21 and 22 are opened halfway. (Step B2).

  Here, the case where the side sensors 17 of both the casings 21 and 22 are “ON” and the close sensor 14 and the open sensor 15 are “OFF” is a case of a vertical stand (in step B2). If YES, if the close sensor 14 and the open sensor 15 are not “OFF” but are in a form other than the stand (NO in step B2), the flow exits. If it is in the state of the vertical stand (YES in step B2), it is checked whether an application dedicated to the vertical stand is in operation (step B3). (Step B4). Then, it is checked whether the current display direction is the α direction with the direction of the hinge portion 23 downward (step B5). Even in the stand state, the current display direction is not the α direction (NO in step B5). If the flow exits from this flow but is in the α direction (step B5), the direction is changed to the β direction with the direction of the hinge portion 23 facing up (step B6).

  If the detection signals from the side sensors 17 of both the casings 21 and 22 change from “ON” to “OFF” (NO in step B1), both the casings 21 and 22 are separated from the desk surface or the like. Since the vertical stand is released, it is checked whether an application dedicated to the vertical stand is in operation (step B7). If it is not in operation, the flow exits from this flow, but if it is in operation (step If YES in B7), the application is terminated (step B8). Then, it is checked whether the previous display direction is the β direction, that is, whether the display direction is the β direction when each side sensor 17 is “ON” (step B9). If NO, the flow goes out of this flow, but if it is in the β direction (YES in step B9), the display direction is changed to the α direction (step B10).

  As described above, in the second embodiment, it is possible to specify a stand form in which both housings 21 and 22 are opened halfway, and to execute a predetermined process, and both housings 21 and 22 are opened halfway. It can be used in a state suitable for the stand form. For example, the camera function, TV function, video playback function, etc. can be activated when both housings 21 and 22 are placed on a desk or the like in the form of a stand that is partially opened. Can be used.

  With reference to the detection results from the side sensors 17 and the close sensor 14 of both the casings 21 and 22, the side sensor 17 provided on the side surface located on the opposite side of the hinge portion 23 in both casings 21 and 22 is “ON”. "If the close sensor 14 is" OFF ", it can be determined that the stand is vertically placed. In this vertical stand, the display direction can be changed so that the side portion in contact with the desk or the like is on the lower side, and a display state suitable for the vertical stand can be obtained.

  When it is determined that it is in the stand form, a specific application (stand-dedicated application) is started as a predetermined process, so simply changing the style to the stand form and using an application suitable for that style be able to.

  Since it is determined that the display direction is changed when it is determined that the display is in the stand form, the display content suitable for the style can be obtained simply by changing the style to the stand form.

  When both the casings 21 and 22 are separated from the desk surface and the vertical stand is released, the specific application is terminated and the display direction is restored to the original state. It is possible to return to the original state only by changing to the form.

  In addition, in the second embodiment described above, the case where it is used in a vertical stand is illustrated, but as shown in FIG. 22 may be used in a horizontal stand in which one side surface portion (one side surface portion located on the side orthogonal to the hinge portion 23) is placed on a desk surface or the like. In this case, if the side sensors 16 of the housings 21 and 22 are “ON” and the close sensor 14 is “OFF”, it can be determined that the case is a horizontal stand. In this horizontal stand, the display direction can be changed so that the side portion in contact with the desk or the like is on the lower side, and a display state suitable for the horizontal stand can be obtained.

Further, in the second embodiment described above, the present invention is not limited to a vertical stand and a horizontal stand, and may be used in a laying stand as shown in FIG. This laying stand is in a half-open state in which both housings 21 and 22 are opened halfway, and is placed on a desk surface or the like with the outer surface (back surface) of the operation unit housing 21 facing down. If the bottom surface sensor (contact sensor) 18 is provided on the outer side surface (back surface), and the bottom surface sensor 18 is “ON” and the close sensor 14 is “OFF”, it can be determined that it is a sleeping stand. In the drawing, black circles conceptually show the bottom sensor 18. The display direction on the laying stand is such that the outer surface of the operation unit housing 21 that is in contact with the desk surface or the like is on the lower side, that is, the rising direction of the display unit housing 22 is upward and the hinge portion 23 is The direction is the downward direction (α direction).
In addition, in the second embodiment described above, the display direction is reversed up and down, but the display content itself may be changed.

(Example 3)
A third embodiment of the present invention will be described below with reference to FIGS.
In the above-described second embodiment, the case where the present invention is applied to a foldable mobile phone device has been shown. However, in this third embodiment, two casings are connected to each other so as to be foldable and openable and rotatable. The present invention is applied to a two-axis type mobile phone device, and a predetermined process is executed when the two-axis type mobile phone device is used in a stand form.
Here, in the first and third embodiments, the same or the same names in the first embodiment are denoted by the same reference numerals, the description thereof will be omitted, and the following description will be focused on the characteristic portions of the third embodiment. It shall be.

FIG. 10 is an external view of a two-axis mobile phone device.
The cellular phone device is configured such that the operation unit housing 21 and the display unit housing 22 are connected to each other by a hinge unit 23 so that the operation unit housing 21 and the display unit housing 22 can be folded, opened, and rotated. And an opening / closing hinge shaft for folding and opening / closing 22 and a rotation hinge shaft that is substantially orthogonal to the opening / closing hinge shaft and rotates one housing relative to the other housing. The operation unit housing 21 and the display unit housing 22 are connected to each other via the hinge unit 23 so as to be foldable and openable and rotatable.

  FIG. 10A shows a closed style in which the display unit casing 22 is folded and completely closed with respect to the operation unit casing 21, and FIG. Thus, an open style in which the display unit housing 22 is completely opened is shown. In this open style, the display direction of the main display unit 7 is the α direction (the direction in which the direction of the hinge unit 23 is down). FIG. 10C shows an anti-open style in which the display unit housing 22 is rotated 180 degrees with respect to the operation unit housing 21 in this open style state.

  FIG. 10D shows a view style in which the display unit housing 22 is folded with respect to the operation unit housing 21 in the anti-open style state and is completely closed. In this view style, the display direction of the main display unit 7 is the β direction (the direction in which the direction of the hinge unit 23 is directed upward). FIG. 10E shows a vertical position in which the operation unit casing 21 and the display unit casing 22 are opened halfway in the anti-open style or view style, and the casings 21 and 22 are both legs and stand on a desk surface or the like. It is the figure which showed the stand style. In this stand style, the display direction of the main display unit 7 remains the β direction.

  FIG. 11 shows a sensor used in a two-axis type mobile phone device, and a rotation sensor 19 is provided in addition to the above-described open / close sensors (close sensor 14 and open sensor 15). The rotation sensor 19 is configured such that the display unit housing 22 is rotated with respect to the operation unit housing 21 in order to change from the open style to the anti-open style or from the anti-open style to the open style. When the rotation angle is 0 degree, it is detected that the main display part 7 is facing inward, and when it is 180 degrees, the main display part 7 is facing outward. Is detected.

  FIG. 12 is a diagram for explaining operating states of the close sensor 14, the open sensor 15, and the rotation sensor 19 according to each style. In the figure, “inside” and “outside” indicate the orientation of the main display unit 7. When the rotation angle detected by the rotation sensor 19 is 0 degree, the main display unit 7 faces inward. , 180 degrees indicates that the main display unit 7 faces outward. The CPU 1 determines the current style based on the detection results of the close sensor 14, the open sensor 15, and the rotation sensor 19. That is, when the close sensor 14 is “ON” and the rotation sensor 19 is “inside”, it is closed style, and when the open sensor 15 is “ON” and the rotation sensor 19 is “inside”, it is open style. Determine. When the open sensor 15 is “ON” and the rotation sensor 19 is “outside”, the anti-open style is used. When the close sensor 14 is “ON” and the rotation sensor 19 is “outside”, the view style is closed. When the sensor 14 and the open sensor 15 are “OFF” and the rotation sensor 19 is “outside”, it is determined that the stand style is used.

FIG. 13 is a flowchart showing a display control process that is started when the detection signal from the open / close sensor (close sensor 14 or open sensor 15) changes.
First, the CPU 1 refers to the detection result of the rotation sensor 19 when the detection signal of the open / close sensor (ON to OFF or OFF to ON) changes, and whether the current rotation state is “outside”. (Step C1). If the main display portion 7 is facing outward, that is, if the current rotation state is “inside” (NO in step C1), the detection signal of the open / close sensor has changed. (Step C2).

  If there is a change in the detection signal of the close sensor 14 (YES in Step C2), whether the detection signal has changed from “OFF” to “ON”, that is, the close that is completely closed by the change in the closing direction. It is checked whether the style has been reached (step C3). When the closed style is selected (YES in step C3), display off processing is performed to erase the contents of the main display unit 7 at that time (step C4). When the body 22 starts to open (NO in step C3), display-on processing is executed at that time, and a standby screen or the like is displayed on the main display unit 7 in the α direction (direction in which the direction of the hinge unit 23 is down). (Step C5).

  On the other hand, if the current rotation state is “outside” (YES in step C1), it is checked whether the open sensor 15 has changed in the detection signal of the open / close sensor (step C6). When there is a change in the detection signal (YES in step C6), whether the detection signal has changed from “OFF” to “ON”, that is, by a change in the opening direction with the main display portion 7 facing outward. It is checked whether the anti-open style has been reached (step C7). Now, if the detection signal of the open sensor 15 changes from “ON” to “OFF”, that is, changes in the closing direction when starting to close to shift from the anti-open style to the view style or the stand style. (NO in Step C7) At that time, the display direction of the main display unit 7 is changed from the α direction to the β direction and the direction of the hinge unit 23 is set downward (Step C10). Start (step C11).

  Further, when the detection signal of the open sensor 15 changes from “OFF” to “ON” due to the change in the opening direction with the main display portion 7 facing outward, the anti-open style (step) In step C8, the display direction of the main display unit 7 is changed from the β direction to the α direction to change the direction of the hinge unit 23 downward (step C8). End (step C9).

  If the detection signal of the close sensor 14 is changed with the main display portion 7 facing outward (NO in step C6), has the detection signal changed from “ON” to “OFF”? In other words, it is checked whether the change is from the view style to the opening direction (step C12). If the change is from the view style to the stand style or the anti-open style, the opening direction is changed to the opening direction (step C12). If YES at C12), an application dedicated to the stand is started (step C11). In this case, the display direction of the main display unit 7 is not changed, and the β direction remains unchanged. Further, when the change in the detection signal of the close sensor 14 changes from “OFF” to “ON”, that is, from the stand style or the anti-open style to the view style (NO in step C12), the stand is changed at that time. The dedicated application is terminated (step C13).

  As described above, in the third embodiment, the operation unit casing 21 and the display unit casing 22 are folded and connected to the hinge unit 23 so that the operation unit casing 21 and the display unit casing 22 can be freely opened and closed. The case 21 and the display unit case 22 are opened halfway, and the predetermined form is executed by specifying the stand form in which the display unit case 22 is rotated so that the main display unit 7 of the display unit case 22 faces outward. The camera function, television function, video playback function, etc. can be activated when placed on a desk or the like in the form of a stand, and can be used in a state suitable for the form of the stand.

  Based on the detection results of the close sensor 14, the open sensor 15, and the rotation sensor 19, it can be determined that the stand style is used. That is, when the close sensor 14 and the open sensor 15 are “OFF” and the rotation sensor 19 is “outside”, it can be easily determined that the stand style is used.

  In addition, as in the second embodiment described above, the third embodiment can use an application suitable for the style (an application dedicated to the stand) simply by changing to the stand form. Moreover, the display content suitable for the stand form can be obtained simply by changing to the stand form. Moreover, it can return to the original state only by changing the style from the stand form to another form.

  In each of the above-described embodiments, the close sensor 14 constituting the open / close sensor is configured by a micro sensor so that an ON signal is output while a complete close is detected. In this case, the close detection may be performed. Further, in each of the above-described embodiments, the open sensor 15 constituting the open / close sensor is configured by a micro sensor. However, whether or not the two casings are opened is detected by the acceleration sensor, and is the stand configuration based on the detection result? You may make it discriminate | determine. In this case, the image may be displayed with trapezoidal correction according to the degree of opening of both housings obtained by the acceleration sensor and the tilt state of the main display unit 7 or the sub display unit 8.

In each of the embodiments described above, the display direction is inverted up and down, but the display content itself may be changed without being limited to display inversion.
In addition, the present invention is not limited to the mobile phone device, and can be similarly applied to a mobile terminal device such as a PDA, an electronic camera, an electronic wristwatch, and a music player.
