Power supply system and electronic instrument

An electronic instrument, comprising:

• a second plurality of loads configured to be supplied with power from a battery;
• a first plurality of power supply units configured to supply working voltages from a battery to the second plurality of loads;
• a large-capacitance capacitor configured to charge electric charges from the battery;
• a third plurality of switching means for connecting the large-capacitance capacitor to the second plurality of loads selectively;
• and
• control means for switching the third plurality of switching means corresponding to at least one load presently in use among the second plurality of loads.
