  As shown in FIG. 2, the cellular phone mainly includes a first housing 22 and a second housing 24. Here, the mobile phone is assumed to have two housings, but it may have only one housing having a display portion, or may be divided into three or more having a display portion in at least one housing. You may have a housing | casing.

  With reference to FIG. 2, a protrusion 28 is attached to the first housing 22. A hinge portion 23 is attached to the protruding portion 28 so as to be rotatable about a virtual axis A1 as a rotation axis so as to be connected to both left and right ends of the protruding portion 28. A second housing 24 is attached to the hinge portion 23 so as to be rotatable with respect to the hinge portion 23 about a virtual axis A2 as a rotation axis. The hinge portion 23 includes a hinge for rotating the second casing 24 about the axis A2 and a hinge for rotating the second casing 24 about the axis A1 and folding it. Each hinge has the same mechanism, and with respect to the hinge to be rotated, a magnet is provided on the case 24 side at the boundary between the hinge part 23 and the case 24, and the magnet is provided on the hinge part 23 side. It has a sensor that detects whether or not it is in contact (detects a magnetic field). Regarding the hinge for folding, a magnet is provided on one side near the speaker 17 and the microphone hole 18A, and a sensor for detecting a magnetic field related to the magnet is provided on the other side. These sensors that detect the magnetic field constitute a hinge sensor 10.

  Based on the detection results of the two sensors, the CPU 11 determines whether the casing 24 is in the open state of FIG. 2, the casing is folded (see FIG. 3), or the axis 24 in the state of FIG. 2. It is detected whether it is in a rotating state or a state in which the housing 24 is rotating in the state of FIG.

  Referring to FIG. 2, first casing 22 has an input button on its main surface for the user to input information such as a telephone number, characters and symbols, and to input instructions for starting / stopping various functions. A group 8A and a function button group 8B are provided, and further, a first microphone hole 18A and a second microphone hole 18B for inputting sound to the microphone 18 are provided. A shutter button 8 </ b> C of the camera 19 is provided on the side surface of the first housing 22. The operation input unit 8 includes an input button group 8A, a function button group 8B, and a shutter button 8C.

  The second casing 24 includes a display screen 4A of the LCD display unit 4 and a speaker 17 on the main surface.

  Here, the 5-axis sensor 5 will be described. Referring to FIG. 4A, the 5-axis sensor 5 is built in a second casing 24 having a display screen 4A. When the second casing 24 of the mobile phone is placed so as to be horizontal with the ground, the 5-axis sensor 5 has two axes (X axis and Y axis) orthogonal to each other in the horizontal plane, and each of these two axes. And a magnetic sensor 52 for detecting a geomagnetic component in each direction of the X, Y, and Z axes, and each of the X and Y axes. And an acceleration sensor 51 for detecting a gravitational acceleration component in the direction. The acceleration sensor 51 derives, as an output 16, a gravitational acceleration component signal XV1 in the X-axis direction and a gravitational acceleration component signal YV1 in the Y-axis direction, which are voltage signals (mV). The magnetic sensor 52 derives the geomagnetic component, which is a voltage signal (mV) for each of the X axis, the Y axis, and the Z axis, as the output 16 using the geomagnetic component signals XV2, YV2, and ZV2. The acceleration sensor 51 and the magnetic sensor 52 are not simultaneously activated, and one is selectively activated. That is, both receive the selection instruction signal 15 output by the CPU 11 of the control unit 7, and when the input selection instruction signal 15 indicates selection of the acceleration sensor 51, the acceleration sensor 51 detects and outputs the output 16. When the instruction signal 15 indicates selection of the magnetic sensor 52, the magnetic sensor 52 performs a detection operation and derives the output 16.

  In the mobile phone, as described above, the 5-axis sensor 5 is built in the second casing 24 provided with the display screen 4A, and extends along the main surface of the second casing 24 and the back surface of the main surface. An X axis and a Y axis are defined in the plane, and a Z axis is defined in a direction perpendicular to the main surface and the back surface thereof.

  In the mobile phone according to the present embodiment, the wallpaper of the display screen 4A of the LCD display unit 4 is switched according to the direction in which the second casing 24 faces and the degree of inclination with respect to the ground.

  The CPU 11 detects the direction in which the second housing 24 is facing based on the output 16 of the magnetic sensor 52. Further, based on the Z-axis geomagnetic component signal ZV <b> 2 in the output 16 of the magnetic sensor 52, it is detected whether the second casing 24 faces front or back.

  FIG. 5 shows an example of the type of orientation to be detected. Referring to FIG. 5, the detected azimuths are azimuths (1) to (8) (circles in the figure) based on east (E), west (W), south (S), and north (N). 8 types) (indicated by the attached numerical values). Here, although the number of azimuths is eight, it is not limited to eight. Further, the number of divisions of this direction may be set in advance by the manufacturer, or may be arbitrarily changed by the user. In FIG. 5, east (E) is set as the base point (0 °), and directions (1) to (8) are made every 45 ° as it goes from north (N) to west (W) to south (S) to east (E). Is divided. For example, when the output 16 of the magnetic sensor 52 indicates a voltage level corresponding to a range of 45 ° in the north (N) direction from the east (E), the CPU 11 has the orientation (1). It is detected (decided) when it is suitable for.

  6A and 6B show examples of determining the orientation. 6A shows a state in which the mobile phone is opened (see FIG. 2), FIG. 6B shows a state in which the mobile phone is folded, and the second housing 24 rotates about the axis A2. The state in which the display screen 4A is directed to the side opposite to the first housing 22 side by moving is shown. The direction (direction) in which the mobile phone is facing is determined using the orientation reference provided on the mobile phone. Since the 5-axis sensor 5 is built in the second housing 24 side, the projection 28 to which the hinge portion 23 is attached is directed to the LCD display portion 4 (display screen 4A) as indicated by an arrow in the figure. The direction of the Y axis in FIG. 5A is considered as a reference for the orientation of the mobile phone. Therefore, in the case of FIG. 6 (A), the orientation of the mobile phone is detected as the orientation (2). However, when the mobile phone is folded as it is and in the state of FIG. 6 (B), the orientation of the mobile phone is The direction (6) is detected.

  For such azimuth detection, the ROM 12 stores an azimuth table 142 as shown in FIG. The azimuth table 142 stores the signal level (mV) of the output 16 of the magnetic sensor 52 when the mobile phone is directed to the azimuth corresponding to each of the azimuth data 160 indicating the azimuths (1) to (8). Yes. The signal level of the output 16 corresponding to the azimuth is obtained in advance by experiments or the like.

  Therefore, the CPU 11 reads the azimuth data 160 corresponding to the level of the output 16, that is, the azimuth to which the second casing 24 is directed, by searching the azimuth table 142 based on the level of the output 16 of the magnetic sensor 52. Can be put out.

  Next, a procedure for changing the wallpaper to be displayed based on the information indicating whether the mobile phone is in the front or back direction and the direction information will be described.

Example 1
For example, as shown in FIGS. 8A to 8F, the orientation of the front and back of the mobile phone is whether the display screen 4A is opposed to the ground, that is, facing down, or opposite to the ground. It is defined by whether it is facing, that is, face up. Assuming that the paper surface of FIG. 8 is the ground, FIG. 8 (A) is defined as facing the front, and FIG. 8 (B) is defined as FIG. It is defined that the mobile phone itself is turned 180 ° from the state, and is turned to the back. In the state of FIG. 8B, the casing 24 is rotated about the axis A2 to display the display screen 4A in FIG. 8 (C) rotated 180 ° from the state of FIG. 8 is defined as facing the front, and the state of FIG. 8 (D) when the mobile phone itself is rotated 180 degrees from the state of FIG. 8 (C) is , Defined as facing away. On the other hand, FIGS. 8E and 8F show a state in which the housing is folded. FIG. 8E shows a state after the housing is folded from the state of FIG. 8A or FIG. 8C. 8E is assumed to face the back, and FIG. 8F is assumed to face the front. Here, FIG. 8E shows a state in which the display screen 4A cannot be viewed from the outside, and it can be said that it is not necessary to control any display including wallpaper. Here, the state shown in FIG. 8E is referred to as “CLOSE back”.

  With reference to FIG. 9, the front side and the back side will be further described. Referring to FIG. 9, it is determined that the surface of the second casing 24 on which the display screen 4 </ b> A is provided faces frontward when facing the solid arrow direction of FIG. 9 with respect to the ground, and facing down when facing the broken arrow direction. The Whether it is face up or face down is determined based on the level of the geomagnetic component signal ZV2 of the magnetic sensor 52 in the Z-axis direction.

  Specifically, the CPU 11 determines whether it is front-facing or back-facing based on the geomagnetic component signal ZV2 in the output 16 derived from the magnetic sensor 52. 141 is referred to. The front / back table 141 stores the width (range) of the signal level (mV) of the geomagnetic component signal ZV2 corresponding to each of the “front” and “back” of the front / back data 140. The width of the level of the geomagnetic component signal ZV2 corresponding to the orientation of the “front” or “back” as shown in FIGS. 8A to 8F is obtained in advance by experiment and stored in the front-back table 141. ing.

  Here, the level of the geomagnetic component signal ZV2 of the front / back separate table 141 is registered with a predetermined width (range), but it may be registered with one value instead of a value having a width (range). That is, when the surface of the second casing 24 on which the display screen 4A is provided is horizontal with respect to the ground and faces the solid arrow direction in FIG. When the orientation is determined, the level of the geomagnetic component signal ZV2 is registered in the front / back separate table 141 for each of the front and back sides.

  Therefore, the CPU 11 searches the front / back table 141 based on the level of the geomagnetic component signal ZV2 detected at that time, reads out the front / back data 140 corresponding to the range corresponding to the level, and stores the second data at that time. It can be determined whether the orientation of the housing 24, that is, the orientation of the mobile phone is “front” or “back”. As a result of the search, if the detected level of the geomagnetic component signal ZV2 does not correspond to any of the levels of the geomagnetic component signal ZV2 registered in the front / back separate table 141, the CPU 11 determines “undefined” as the search result.

  Thus, the CPU 11 switches the wallpaper displayed on the LCD display unit 4 according to the orientation and orientation (front or back) of the mobile phone determined based on the output 16 of the 5-axis sensor 5. For this purpose, the CPU 11 refers to the wallpaper setting information 62 in the storage unit 6.

  The wallpaper setting information of the first embodiment has a plurality of records as shown in FIG. Each record includes setting name data 621, orientation data 622, front / back data 623, and wallpaper identifier 624 in association with each other. The setting name data 621 is data for uniquely identifying the record. The orientation data 622 is data indicating the types of orientations (1) to (8) shown in FIG. The front / back data 623 is data indicating the front or back type of the mobile phone. The wallpaper identifier 624 is information for uniquely identifying image data for a plurality of types of wallpaper stored in advance in the wallpaper data area 61 of the storage unit 6. In FIG. 11, it can be seen that the image data displayed as the wallpaper is set differently depending on the orientation of the mobile phone and the front / back.

  Next, the wallpaper switching control displayed on the LCD display unit 4 according to the first embodiment will be described with reference to the flowcharts of FIGS. The program according to the flowcharts of FIGS. 12 and 13 is stored in the ROM 12 in advance, and the CPU 11 reads out and executes the program instructions from the ROM 12 to execute the processing of FIG. 12 or FIG. Here, it is assumed that the program according to the flowchart of FIG. 12 is periodically started at predetermined intervals. When the program according to the flowchart of FIG. 12 is being executed at the time when the periodic activation timing is reached, the execution is started when the execution is completed.

  It is assumed that some kind of image is displayed on the LCD display unit 4 at the start of the processing of FIG.

  In the first embodiment, when it is detected by the processing according to the flowchart of FIG. 12 that some acceleration is applied to the mobile phone, the CPU 11 detects acceleration data detected based on the output 16 of the acceleration sensor 51. When a change in acceleration is detected based on a comparison result between the acceleration data AS previously detected stored in the RAM 13 and the panorama wallpaper processing routine shown in FIG. 13 is started. In the processing routine of FIG. 13, based on the output 16 of the magnetic sensor 52, the azimuth table 142 and the front / back separate table 141 are searched to read the azimuth data 160 and the front / back separate data 140. The CPU 11 compares and collates the read direction data 160 and front / back data 140 with the direction data 622 and front / back data 623 stored in each record of the wallpaper setting information 62. Based on the wallpaper identifier 624 stored in the record, the corresponding wallpaper data is read from the wallpaper data area 661 and the wallpaper based on the wallpaper data is displayed on the LCD display unit 4. A specific procedure will be described below.

  Referring to FIG. 12, first, the CPU 11 turns on the 5-axis sensor 5 (starts supplying power from the power supply unit 9), and selects a selection instruction signal 15 for selecting and activating the acceleration sensor 51. Therefore, the acceleration sensor 51 is activated. Then, the CPU 11 inputs an output 16 composed of acceleration component signals XV1 and YV1 derived from the acceleration sensor 51 (step T (hereinafter abbreviated as T) 1). Then, the output 16 is converted into acceleration data given to the second casing 24 by the mobile phone, the acceleration data obtained by the conversion and the previously stored acceleration data AS stored in the RAM 13 in advance. And whether or not there is a difference based on the comparison result, that is, whether or not acceleration is given to the second casing 24 (that is, whether or not the second casing 24 has moved) is determined ( T3). The acceleration data AS is reset (set to an initial value, for example, “0”, etc.) every time the mobile phone is turned off. Here, as a result of the comparison described above, if there is a difference, it is determined that acceleration has been given, but the present invention is not limited to this determination procedure. For example, the difference may be compared with a predetermined value, and it may be determined that the acceleration is applied when the difference exceeds the predetermined value as a result of the comparison.

  If there is no difference as a result of the above determination, it is determined that acceleration is not applied to the second casing 24, that is, the mobile phone is not moving (NO in T3), and the 5-axis sensor 5 is off (power supply) (T11), and the series of processing ends. On the other hand, if there is a difference, that is, if acceleration is given to the second casing 24 and it is determined that the mobile phone is moving (YES in T3), the CPU 11 uses the acceleration data acquired this time. The acceleration data AS in the RAM 13 is updated.

  Next, the CPU 11 inputs the output of the hinge sensor 10 (T5), compares the output value of the hinge sensor 10 with the threshold value data HD stored in the ROM 12, and the mobile phone is displayed based on the comparison result. It is determined whether or not the CLOSE state of 8 (E) is present (T7). The threshold data HD is data indicating the output of the hinge sensor 10 when it is in the state behind the CLOSE, and is assumed to be acquired in advance by an experiment or the like. As a result of the comparison, if the output value of the hinge sensor 10 matches the value of the threshold value data HD, it is not necessary to control any display including the wallpaper, so the process of T11 is performed and the series of processes ends. . Otherwise, the CPU 11 activates the panoramic wallpaper processing routine of FIG.

  Thus, when acceleration is not detected and it is not detected that the second casing 24 has moved, or when it is detected that the state is the back of the CLOSE, the power supply to the 5-axis sensor 5 is turned off and the magnetic sensor 52 is turned off. Since the used azimuth detection and inclination (separate) are not detected, unnecessary detection operation can be avoided, and unnecessary power consumption can be avoided.

  In the panorama wallpaper processing routine, first, the CPU 11 determines whether or not the panorama wallpaper mode has been set effectively by the user by operating a predetermined key of the operation input unit 8 (step S (hereinafter simply abbreviated as S). 1). If the panorama wallpaper mode is not set to be valid (NO in S1), the panorama wallpaper processing routine is terminated, and the process returns to the process of FIG. On the other hand, if it is determined that the panoramic wallpaper mode is set to be valid (YES in S1), the direction / front and back information is detected (S5).

  Specifically, the magnetic sensor 52 is activated using the selection instruction signal 15, and based on the output 16 derived by the activated magnetic sensor 52, the orientation table 142 of FIG. And the corresponding back-and-back data 140 are read by searching the front-and-back table 141 based on the Z-axis geomagnetic component signal ZV2 in the output 16.

  Thereafter, the CPU 11 compares and compares the read direction data 160 and front / back data 140 with the direction data 622 and front / back data 623 of each of the plurality of records indicated by the setting name data 621 of the wallpaper setting information 62 ( S7, S19,..., S31). As a result of such comparison with each record, if it is determined that a record storing orientation data 622 and front / back data 623 that match the read orientation data 160 and front / back data 140 is not registered ( In S31, the LCD display unit 4 returns to the process of FIG. 12 while displaying the image at the start of the process of FIG.

  On the other hand, in the comparison with each record of the wallpaper setting information 62, when the record storing the orientation data 622 and the front / back data 623 that match the read orientation data 160 and the front / back data 140 is specified, The wallpaper identifier 624 of the record is read, the wallpaper data area 61 is searched based on the read wallpaper identifier 624, the corresponding wallpaper data is read, and the wallpaper image based on the read wallpaper data is displayed on the LCD display unit 4 (S9). ).

  Thereafter, the CPU 11 determines whether or not the panoramic wallpaper mode has been invalidated by operating a predetermined key of the operation input unit 8 by the user (S11). When the user operates the operation input unit 8 to switch the panoramic wallpaper mode to invalid, it is determined as invalid (YES in S11), and the processing returns to FIG.

  On the other hand, if it is determined that the panoramic wallpaper mode remains valid (NO in S11), the output of the hinge sensor 10 is input (S15), and based on the output, it is determined whether or not the state is behind the CLOSE. (S17). If the determination result indicates that the state is behind the CLOSE, the process returns to the process of FIG. 12, otherwise returns to the process of S5, and the subsequent procedures are repeated in the same manner.

  In this way, the wallpaper displayed on the LCD display unit 4 can be switched according to the orientation and orientation (backward or front) of the mobile phone.

(Example 2)
In the first embodiment, the orientation (tilt) of the mobile phone is either front-facing or back-facing as shown in FIGS. 8A to 8F, but in this embodiment, the orientation of the mobile phone is The determination is made based on the inclination of the mobile phone (the second casing 24 having the LCD display unit 4) with respect to the ground. According to the discrimination based on the inclination, it is possible to provide not only two front and back directions but also a “middle” direction between them, and a more varied wallpaper changing function can be provided.

  As shown in FIGS. 14 and 15, the orientation of the mobile phone is determined by setting the orientation reference for the mobile phone in the same manner as the orientation of the mobile phone. In the example of FIG. 15, the inclination is 0 ° when the second casing 24 is horizontal to the ground and the display screen 4A is in a direction opposite to the ground. As shown in FIG. 14, according to the tilt angle of the second casing 24, the mobile phone tilt type is determined to be front, back, or intermediate.

  16A to 16C schematically show the degree of inclination of the second casing 24 with respect to the ground when viewed from the longitudinal side surface of the casing of the mobile phone in the open state in FIG. It is shown. With reference to FIGS. 16A to 16C, the relationship between the geomagnetic component signal ZV2 and the inclination of the second casing 24 is shown. 16A to 16C, the broken line L indicates the direction perpendicular to the ground, the straight line A3 indicates the Z-axis direction of the second casing 24, and FIG. And the straight line A3 coincide and overlap. In this embodiment, the inclination of the casing as described above indicates the magnitude of the inclination of the straight line A3 (the Z axis of the second casing 24) with respect to the axis of the broken line L. FIG. 16A shows the second housing 24 when the geomagnetic component signal ZV2 shows a level corresponding to a tilt of 5 °, and FIG. 16B shows the geomagnetic component signal ZV2 having a tilt of 0 °. The second housing 24 is shown when indicating a considerable level. FIG. 16C shows the second casing 24 when the geomagnetic component signal ZV2 shows a level corresponding to an inclination of 355 °.

  Here, the type of inclination is “table” when the signal level of the geomagnetism component signal ZV2 shows a corresponding level in the range of inclination ± 45 ° with reference to 0 °, with reference to FIG. Similarly, in the case of showing an equivalent level in the range of inclination ± 45 ° with reference to 90 ° or the range of inclination ± 45 ° with reference to 270 °, “middle” (not the front or back) is the same. In the case where a considerable level is shown in the range of inclination ± 45 ° with reference to 180 °, “back” is shown.

  In the second embodiment, in addition to the front and back, an “intermediate” direction is provided, so that the front and back separate table 141 has the level of the geomagnetic component signal ZV2 according to FIGS. 14 and 15 as shown in FIG. Front, back, and back data 143 is stored for each range.

  Further, the wallpaper setting information 62 in FIG. 11 is changed as shown in FIG. The wallpaper setting information 62 in FIG. 18 is searched for the wallpaper setting information 62 in FIG. 18 in the same manner as in the first embodiment based on the orientation data 140 read from the orientation table 142 and the front and back separate data 143 read from the front and back separate table 141. Thus, the display wallpaper can be switched using the wallpaper data indicating the wallpaper identifier 624 of the record having the azimuth data 622 and the front / intermediate / back data 625 that match this.

  This embodiment is the same as the first embodiment except that the orientation of the mobile phone is changed to three types, front, back, and middle, and the procedures shown in FIGS. 12 and 13 are similarly applied.

  As described above, in this embodiment, since the wallpaper to be displayed is switched based on the azimuth and inclination (back, front, middle) of the mobile phone, it is possible to change the wallpaper more varied. In addition, by switching according to the direction and orientation, for example, it is possible to switch the wallpaper constituting the panorama image, and the user can view the panorama screen by changing the direction and tilt while holding the mobile phone, The entertainment of time increases.
