| 摘要 | A power consumption control device includes a power consumption control unit that receives the output potential of a photovoltaic cell generating an electromotive force, receives the output potential of a secondary battery charged by the electromotive force of the photovoltaic cell, causes a timepiece device to transition to a power saving state where a clock operation of measuring time is stopped when the output potential difference of the secondary battery is not greater than a predetermined threshold value, and the secondary battery is in a non-charging state indicating a state where the output potential difference of the photovoltaic cell is not greater than the output potential difference of the secondary battery. | ||

| 主权项 | 1. A power consumption control device comprising a power consumption control unit that causes a timepiece device to transition to a power saving state where a clock operation of measuring time is stopped when an output potential difference of a secondary power supply unit charged by an electromotive force of a primary power supply unit is not greater than a predetermined threshold value, and the secondary power supply unit is in a non-charging state indicating a state where an output potential difference of the primary power supply unit is not greater than the output potential difference of the secondary power supply unit. | ||
