Abstract
The CPU of the lens drive unit obtains new data to be stored in an EEPROM from a personal computer. The CPU confirms with a supplied voltage confirmation circuit that voltage supplied from a power source to the lens drive unit is sufficient to reprogram the contents of the EEPROM. When the voltage of the power source is sufficient, a reprogramming voltage is applied from a reprogramming voltage applying device to the EEPROM, and the contents of the EEPROM are reprogrammed with the new data obtained from the personal computer. If the voltage of the power source is insufficient, the reprogramming of the contents of the EEPROM is not performed.
