An electronic apparatus includes solar cells, an accumulation portion that accumulates power generated by the solar cells, an electronic apparatus main body portion that is operated by using power accumulated in the accumulation portion, and an operation control circuit that performs control so that, in a case where a voltage of the accumulation portion increases, an operation of the electronic apparatus main body portion is started if the voltage of the accumulation portion exceeds a first threshold voltage, and, in a case where a voltage of the accumulation portion decreases, an operation of the electronic apparatus main body portion is stopped if the voltage of the accumulation portion is less than a second threshold voltage which is smaller than the first threshold voltage. 1. An electronic apparatus comprising:solar cells;an accumulation portion that accumulates power generated by the solar cells;an electronic apparatus main body portion that is operated by using power accumulated in the accumulation portion; andan operation control circuit that performs control so that, in a case where a voltage of the accumulation portion increases, an operation of the electronic apparatus main body portion is started when the voltage of the accumulation portion exceeds a first threshold voltage, and, in a case where a voltage of the accumulation portion decreases, an operation of the electronic apparatus main body portion is stopped when the voltage of the accumulation portion is less than a second threshold voltage which is smaller than the first threshold voltage.2. The electronic apparatus according to claim 1 ,wherein a difference voltage between the first threshold voltage and the second threshold voltage is higher than a drop voltage of the accumulation portion caused by the operation control circuit starting an operation of the electronic apparatus main body portion.3. The electronic apparatus according to claim 1 ,wherein the operation control circuit includesa first ...
