Claim:
1. An electronic device having a power generation function, comprising: a power generation unit; a power storage unit configured to store electric energy generated by the power generation unit; a device which is operated by the electric energy stored in the power storage unit; a charge detection unit configured to detect a charging state from the power generation unit to the power storage unit; a voltage detection unit configured to detect a voltage of the power storage unit; a display operation unit configured to instruct a display of an operation persistence time of the device; a persistence time display unit configured to display the operation persistence time of the device; and an operation control unit configured to control an operation status of the device, wherein the operation control unit includes: an operation suspension portion configured to control the device into an operation suspension state; an operation resuming portion configured to resume an operation of the device when the device is in the suspension state; persistence time display control portion configured to operate the persistence time display unit to display the operation persistence time when the display operation unit is operated; a timer configured to time the remaining time of the operation persistence time; and a timer updating portion configured to update the remaining time of the timer when the charging state is detected by the charge detection unit during an operation of the timer; wherein, the operation resuming portion resumes the operation of the device and operates the timer by setting a persistence time according to the detected voltage when a detected voltage detected by the voltage detection unit is higher than an operation resuming voltage at a time of detecting the charging state by the charge detection unit, wherein the suspension portion controls the device into the operation suspension state when the remaining time becomes 0 (zero) hour, wherein, the operation duration display control portion displays the operation persistence time according to the detected voltage detected by the voltage detection unit by the persistence time display unit and operates the timer by setting the persistence time when the display operation unit is operated; and wherein the timer updating portion updates the remaining time of the timer to the operation persistence time according to the detected voltage when the operation persistence time according to the detected voltage detected by the voltage detection unit is longer than the remaining time of the timer in operation, and operates the timer in operation as it is when the operation persistence time according to the detected voltage is not longer than the remaining time of the timer in operation.
