PROBLEM TO BE SOLVED: To charge a power source by pulling a string and a generator section in an information apparatus such as a mobile phone. SOLUTION: This information apparatus includes: a winder 21 which can be rotated by the string 1 wound around a rotating center shaft and is energized in a string 1 winding direction; a rotary alternator 31 using a rotor as a permanent magnet; and a storage battery 52 for performing charging through a rectifier 51, or a slit or a pole in which a slide piece provided in a prescribed case and fixed at the string 1 can slide; a linear alternator 32 having magnets which are interlocked with the movement by the slide of the slide piece along the slit or the pole and of which N pole and S pole are respectively arranged along the movement direction and a coil for generation provided around the movement range of the magnet; and the storage battery 52 for charging through the rectifier 51, thus charging based on the power supply with the storage battery 52.
