Abstract
A signal recording/reproducing apparatus includes a first power source unit which generates necessary electric power signals from a commercial power source, a second power source unit which generates a necessary electric power signal from a battery, a recording signal processing unit, and a reproduced signal processing unit. The apparatus further includes time measuring instrument which is supplied with the electric power from the second power source unit, and a charging unit which charges the battery with the electric charges. Whenever the time measuring instrument measures a predetermined time, the generation of the electric power signals from the first power source unit is started, and the battery is charged with the electric charges by the charging unit.
