<P>PROBLEM TO BE SOLVED: To prevent electric destruction of a recording medium accompanying installation/uninstallation. <P>SOLUTION: A control processing part 110 sends a light emission instruction to a light emission part when an operation panel 102 is in an "open state". The light emission part emits light of a prescribed wavelength such that a finger or the like of a user advances along a route passing an area becoming a light block body in time of installation/uninstallation operation of a memory card MCD. Though the light is normally detected by a light reception part 140, the light is blocked by the finger or the like when the user brings the finger or the like close to a memory card storage unit 120 so as to perform installation/uninstallation of the memory card MCD to the memory card storage unit 120. The control processing part 110 issues a control instruction of the effect that power of the memory card storage unit 120 should to be turned off to a power supply part 130 when deciding that the light from the light emission part is not detected based on a detection result from the light reception part 140. <P>COPYRIGHT: (C)2008,JPO&INPIT |
