The rebooting module reboots the device if continuous operation time of the button exceeds a first time. Date and time information indicating date and time is stored in the memory. The date and time information becomes an initial value at a time of rebooting the device by the rebooting module. The control module stores the date and time information in the non-volatile storage if continuous operation time of the button exceeds a second time which is shorter than the first time. |
