1. An electronic apparatus comprising:
a power generation module including a power generation unit and a first capacitor unit configured to store power generated by the power generation unit;
a detection device;
a drive unit including a plurality of circuits including a circuit configured to output a voltage to the detection device based on power of the power generation module;
a second capacitor unit electrically coupled in parallel to the first capacitor unit; and
a portable housing configured to accommodate the power generation module, the detection device, the drive unit, and the second capacitor unit, wherein
the drive unit includes:
a first power supply circuit configured to output a first voltage to the detection device based on the power of the power generation module;
a first control circuit configured to control a first drive timing at which the first power supply circuit starts outputting the first voltage;
a second power supply circuit configured to output a second voltage from the first voltage; and
a second control circuit configured to control a second drive timing at which the second power supply circuit starts outputting the second voltage, and
the second control circuit delays the second drive timing from the first drive timing by a predetermined time.
