Electronic apparatus
First Claim
1. An electronic apparatus comprising:
- a power supply having a battery;
a load;
a load driver that drives said load by said battery;
a power supply state detector that outputs power supply recovery information, wherein said power supply recovery information is obtained by repeatedly sampling a measured voltage value of said battery at predetermined intervals of time beginning at a start time, measured after a time said driving of said load is stopped, said sampling being performed under the condition that said battery has not recovered after the driving of said load is stopped; and
a controller that instructs said load driver to drive said load, based on said power supply recovery information supplied from said power supply state detector,wherein said controller controls said power supply state detector so as to select said predetermined intervals of time, each of which is different in duration, or selects a starting time for sampling the measured voltage of said battery from a plurality of starting times after said driving of said load is stopped.

Abstract
The invention provides a compact and highly reliable electronic apparatus that can be driven by a small-capacity battery, and that can achieve high-speed continuous driving of a load by quickly judging the recovery state of the battery after driving the load. More particularly, the invention provides an electronic apparatus includes a power supply, a load, a load driver for driving the load by the power supply, a power supply state detecter for outputting power supply recovery information by measuring physical quantity of the power supply at predetermined intervals of time after the driving of the load is stopped, and a controller for instructing the load driver to drive the load, based on the power supply recovery information supplied from the power supply state detecter.
