Abstract

A signal recording apparatus including a battery voltage detecting circuit. The battery voltage detecting circuit detects the voltage value of a battery. When a record button provided on an operation panel is pressed, a syscon detects, for 160 ms, voltage values given from the battery voltage detecting circuit. The detected voltage values are stored to a DRAM. An average calculated of the voltage values of for 160 ms by using the DRAM. The syscon compares the averaged voltage value with a threshold A that makes it possible for recording for one disk. When the averaged voltage value is equal to or higher than the threshold A, the syscon directly starts recording. When the averaged voltage value is lower than the threshold A, an insufficient remaining capacity of the battery is displayed on a liquid crystal panel by a display controller.
