<p>Usable time of an electronic apparatus used by a child, young people or the like is certainly limited by an easy operation. An electronic apparatus is provided with an electronic apparatus main body, an external memory device that records a specific code and an OS that makes it possible to carry out multi-task processing, a calendar time timer, and a usable time limitation program. The usable time limitation program is periodically carried out, displays a screen to urge setting or change of a usable time limitation mode and a usable time limitation condition when the external memory device that stores a specific code is connected, requires an input of the setting or change, and stores inputted contents. When the external memory device is not connected, the program reads out a stored usable time limitation mode. When the mode is a mode with a usable time limitation, a usable time limitation condition is checked with the current time. When a condition satisfies the prohibition of usability, the program turns off an electric power source. When the condition does not satisfy the prohibition of usability and the usable time limitation mode is a mode without an usable time limitation, the program does not turn off the electric power source.</p> |
