<p><P>PROBLEM TO BE SOLVED: To provide an electronic apparatus mounted with a solar battery in which a solar battery panel can be disposed in a direction at such an angle that efficient photodetection can be performed within a prescribed time. <P>SOLUTION: A mobile phone 1 includes a display-unit side case 3 mounted with the solar battery panel 90; an operation-unit side case 2 coupled to the display-unit side case 3 to freely be opened and closed; an encoder 123 which detects the opening/closing angle of the display-unit side case 3 and operation-unit side case 2; a GPS unit 121 which measures the position of the mobile phone 1; a direction sensor 122 which measures the direction of the mobile phone 1 at a prescribed position; a timer unit 125 which acquires date and time information; an operation unit 106 which inputs a photodetection time for which the solar battery panel 90 photodetects light; and a CPU 100 which calculates a target opening/closing angle and a target direction suitable for the photodetection of the solar battery panel 90 on the basis of the photodetection time, position and date and time information. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
