<p>PROBLEM TO BE SOLVED: To provide a portable electronic unit of structure, which improves the capacity of a power battery in a portable electronic unit, prolongs running time and in which a backup built-in battery at the time of exchanging a built-in battery for clock function for a power main battery does not interrupt the mounting of other devices and a circuit board, which are stored in a main body part. SOLUTION: A power paper battery 11 is stored in a gap formed between a rear armor casing 4a and a reinforcing inner casing as a storage part. The power paper battery 11 is integrally formed with a circuit board where the safety circuit of the paper battery main body and the driving circuit of a liquid crystal display device 3 are mounted and they are connected in the power paper battery 11. The inverter substrate 12 of the liquid crystal display device 3 is connected to the power paper battery 11 through a power supply cable 13. Power is directly supplied to the liquid crystal display device 3.</p> |
