The function selection key 243 is a key for enabling a predetermined function of the mobile phone 10, and the function assigned to this key differs depending on the manufacturer and model.

  2 to 4 are views showing the appearance of the mobile phone 10 shown in FIG. The mobile phone 10 is a phone configured to be folded around a hinge H. FIG. 2 is a diagram showing the folded state, and a camera lens L is provided on the front surface. FIG. 3 is a diagram in which the mobile phone 10 is opened and the display unit 23 and the operation unit 24 are in front. FIG. 4 is a view of the opened mobile phone 10 as viewed from the back. In this state, the object can be imaged by operating the shutter button toward the object to be photographed with the lens L.

  The idea of the present invention is that, in the leg structure for allowing the mobile phone 10 to stand on its own, the operation mode of the mobile phone is automatically selected by paying attention to the relationship between the operation state of the leg and the functions provided in the mobile phone 10. It is in the point that the operation is simplified by changing the control.

  That is, when the leg of the mobile phone 10 is spread to a certain angle, the user of the mobile phone 10 intends to enable the imaging function using the cameras L1 and L2, or the display screen of the display unit 23 is used as a mirror. It can be considered that there is an intention to use, and a mirror surface that detects the movement state of the leg and changes the operation mode of the mobile phone 10 to the imaging mode and changes to the auto shutter mode, or operates the display unit as a mirror. Configure to change to mode.

  In this case, it is not possible to uniquely distinguish between the auto shutter mode and the mirror mode, but the distinction is made based on the operation mode of the mobile phone 10 at the time when the leg operation is performed. That is, a distinction is made by changing to the mirror mode when the leg is operated when the mobile phone 10 is in the standby mode, and to the auto shutter mode when the leg is operated when the mobile phone 10 is in the camera mode. Can do.

  When the mobile phone 10 operates in the mirror mode, the mirror surface control unit 27 transmits a turn-off signal as a control signal to the backlight control unit 28 that turns off or turns on the backlight of the LCD display unit constituting the display unit 23. The display screen can be used as a mirror surface.

  The function control unit 21 stores the current operation mode of the mobile phone 10 in the operation mode control unit 26, and when the operation mode is changed by various keys of the operation unit 24, the operation mode of the operation mode control unit 26. Change the mode to control the operation mode. The leg motion detection unit 25 detects the state of a self-supporting leg provided in the mobile phone 10 and detects whether or not the leg is opened. As the detection means, for example, an infrared sensor or a microswitch can be used.

  When the mobile phone 10 operates in the mirror mode, the mirror surface control unit 27 transmits a turn-off signal as a control signal to the backlight control unit 28 that turns off or turns on the backlight of the LCD display unit constituting the display unit 23. The display screen can be used as a mirror surface.

  On the other hand, the auto-shutter control unit 29 performs control to enable auto-shutter when the mobile phone 10 is operating in the camera mode, and a specific shutter time is set in the shutter time setting unit 31. If there is no default shutter time, for example, if a default value of 30 seconds is set, control is performed so that the camera shutter operates in 30 seconds.

  In the mobile phone 10, while the function button of the camera mode is operated and the camera mode is stored in the operation mode control unit 26, the leg motion detection unit 25 detects the angle of the leg of the self-supporting leg structure. When it is detected that the leg has been opened, the mode is changed to the auto shutter mode, the state of the operation mode control unit 26 is changed, the auto shutter control unit 29 is enabled, and the auto shutter function is activated.

  On the other hand, when the mobile phone 10 is not operated and the operation mode control unit 26 is operating in the standby mode, the leg motion detection unit 25 detects the angle of the legs of the self-supporting leg structure. When it is detected that the leg has been opened, the mode is changed to the specular mode, the state of the operation mode control unit 26 is changed, the specular control unit 27 is enabled, and the display screen of the display unit 23 is displayed as a specular surface. Controlled by the state.

  It is also possible to distinguish between the auto shutter mode and the specular mode depending on the leg angle in the self-supporting leg structure. A mobile phone according to Example 2 will be described below. The mobile phone 10 according to the second embodiment basically has the same configuration as that of the first embodiment, but is configured to detect an open leg state of a self-supporting leg and control an operation mode.

  When shooting with the camera, that is, the mobile phone 10 fixed, the self-supporting leg 40 shown in FIG. 4 is opened and used. The leg 40 is in the form of a thin plate-like lid that becomes a part of the main body of the mobile phone 10. Accordingly, the lower portion 42 of the leg 40 is curved in cross section along the shape of the main body of the mobile phone 10. FIG. 5 is a diagram showing a leg structure for self-supporting. The leg 40 is attached to the main body of the mobile phone 10 by a rotating shaft 41, and the main body of the mobile phone 10 is provided with micro switches 43 and 44 that detect the opening and closing and the angle of the leg 40.

  When the leg 40 is closed, the microswitch 44 produces an output, and the microswitch 43 produces no output. When the leg is opened at the maximum angle, the microswitch 43 produces an output and the microswitch 44 produces no output. The micro switch 43 also functions as a stopper that stops the rotation of the leg 40.

  When the leg 40 is opened to the second angle set without being opened to the maximum angle, neither the microswitches 43 and 44 produce an output. That is, the angle range when the leg 40 is opened and closed and opened by the microswitches 43 and 44 can be determined. FIG. 6 shows a state in which the leg 40 is opened at a maximum angle (first angle range), and FIG. 7 shows a state in which the leg 40 is opened at a predetermined angle (second angle range) smaller than the maximum angle. Show.

  When the leg 40 is opened at the maximum angle, as shown in FIG. 6, the display screen of the display unit 23 of the mobile phone 10 is independent at an angle of 45 degrees with respect to the user. This angle is suitable for the user to use the display screen as a mirror. On the other hand, when the leg 40 is opened at the second angle, as shown in FIG. 7, the lens L provided on the mobile phone 10 is self-supporting at an angle facing the horizontal direction. This angle is suitable for the user to use the mobile phone 10 as a camera. In other words, the first angle range is set to an angle at which the user can easily use the display screen as a mirror, and the second angle range is set to an angle at which the user can easily use the camera function.

  5 to 7, the leg 40 is configured to open at predetermined specific angles as the first angle range and the second angle range, respectively. If the mechanism is configured to stop at a plurality of angular positions and the opening angle of the leg 40 is detected by an infrared sensor or a rotary switch, the display screen is used as a mirror in the first angle range, and in the second angle range. It can be determined that the camera function is intended to be used, and mirror surface control and auto shutter control can be activated.

  Next, an operation procedure according to the first embodiment for controlling the operation mode according to the operation state of the leg of the mobile phone 10 will be described with reference to the flowchart shown in FIG. In the mobile phone 10, the operation mode control unit 26 is set and operated with an operation mode selected by the user. In the process of step S11, it is determined whether or not the leg motion detection means 25 has been opened by detecting the angle of the leg for self-supporting.

  If it is determined in step S11 that the leg is not opened, the process proceeds to step S15, and the operation mode control unit 26 maintains the current operation mode and returns. If it is determined in step S11 that the leg has been opened, the process proceeds to step S12. In the process of step S12, the operation mode control unit 26 detects whether or not the current operation mode of the mobile phone 10 is the camera mode.

  If it is determined in step S12 that the operation mode control unit 26 is operating in the camera mode, the auto shutter control unit 29 is enabled in step S13, and auto shutter control is performed. As described above, when a specific shutter time is not set in the shutter time setting unit 31, a shutter time set as a default, for example, if 30 seconds is a default value, the camera shutter is set to 30 seconds. Control to work.

  If it is determined in step S12 that the operation mode control unit 26 is not operating in the camera mode, the process proceeds to step S14, the mirror surface control unit 27 is enabled, and the backlight control unit 28 is informed of the display unit 23. A control signal for turning off the backlight of the LCD display unit is sent to bring the display screen into a mirror state.

  The operation procedure described above is a procedure for controlling the operation mode to be changed to the auto shutter mode or the specular mode according to the operation mode of the mobile phone 10 and the operation state of the legs. Angle).

  For example, in the camera mode and the mirror surface mode, the posture of the mobile phone 10 is different, and the angle range for opening the legs for self-supporting is different. That is, when the mobile phone 10 is used as a camera, the posture of the mobile phone 10 is independent at an angle close to vertical. On the other hand, when the mobile phone 10 is used with the display surface as a mirror, the legs are opened and become independent so that the display surface of the mobile phone 10 is inclined. Therefore, it is possible to control the change of the operation mode by detecting the state of the leg with the legs opened, the angle, and the angle range to distinguish between the auto shutter mode and the mirror surface mode.

  In this case, an angle range close to the vertical, which is the posture of the mobile phone 10 when the mobile phone 10 is used as a camera, is set as the first angle range. The angle range smaller than that is set as the second angle range, the posture range when the mobile phone 10 is used as a mirror surface, the angle range of the leg is set in advance, and the leg motion detector 25 moves the leg. Identify the angular range of.

  The flowchart shown in FIG. 9 shows the procedure of such control. In the mobile phone 10, the operation mode control unit 26 is set and operated with an operation mode selected by the user. In the process of step S21, the leg motion detection means 25 detects the angle of the leg for self-supporting and determines whether or not the angle range is opened in the first angle range.

  When the leg motion detection unit 25 determines that the leg is not opened in the first angle range in the process of step S21, the process proceeds to step S22, and the leg motion detection unit 25 moves the leg to the second angle range. Detect whether it is open or not. If the leg is not operated even in the second angle range, the leg motion detection unit 25 determines that the leg is not opened, and proceeds to step S25, where the operation mode control unit 26 selects the current operation mode. Maintain and return.

  If the leg motion detection unit 25 determines that the leg is opened in the first angle range in the process of step S21, the auto shutter control unit 29 is enabled and the auto shutter control is performed in the process of step S23. . When a specific shutter time is not set in the shutter time setting unit 31, control is performed so that the camera shutter operates at the shutter time set by default.

  On the other hand, when the leg motion detection unit 25 determines that the leg is opened in the second angle range in the process of step S22, the mirror surface control unit 27 is enabled in the process of step S24, and the backlight control unit 28 is activated. In response to this, a control signal for turning off the backlight of the LCD display unit of the display unit 23 is sent to bring the display screen into a mirror state.

  In most cases, the autofocus control is used in the camera function. In addition to detecting leg behavior, the result of this autofocus control can also be used. That is, when the mobile phone 10 operates in a mode using the camera function, an appropriate focal length is detected in automatic focal length detection for autofocus. On the other hand, when the camera function is off, the focal length detection can be switched to perform mirror surface control when the focal length is less than a predetermined value, for example, within 1 mm.

  As described above, according to the present invention, in the leg structure for allowing the mobile phone 10 to stand on its own, the operation mode is controlled in association with the operation state of the leg and the function provided in the mobile phone 10. Operations when using functions can be simplified.
