A mobile phone having a self power generating device is provided to be continuously used in case that power does not exist by forming an additional self power generating device in the mobile phone by one body and charging a battery through the self power generating device when the battery of the mobile phone is perfectly consumed or an auxiliary battery is not prepared. A part of a driving source(200) is installed in a battery connecting part formed in a rear surface of a mobile phone case(100), and the other part of the driving source(200) is protruded and formed to the outside to be capable of being directly operated by a user. A rotary gear(300) is engaged with the driving source(200). When the driving source(200) is operated, the rotary gear(300) is rotated. Hooks(410) are formed in both ends of a female gear(400) to transmit rotary force in one direction in case that the rotary gear(300) is rotated in a state when a female gear(400) is engaged with the rotary gear(300). A holding projection(510) on which the hooks(410) of the female gear(400) are held and fixed is formed in an inner circumference surface of a driving transmission gear(500). An outer circumference surface of the driving transmission gear(500) is engaged with a generator gear(610). The driving transmission gear(500) transmits driving force in one direction by the hooks(410). When the generator(610) is rotated by the driving transmission gear(500), a generator(600) generates power. A circuit board(700) converts the power obtained from the generator(600) into a DC level, electrically connects to a mobile phone battery, and charges the self-generated power in the battery. |
