    • A conventional power source apparatus comprising a piezoelectric device has the problem that the quantity of power generation is small. In the case of determining a charging quantity with a constant voltage diode used as a trigger circuit, the trigger circuit has been always operating to make power consumption large to an unnegligible extent as compared with the quantity of power generated by the piezoelectric device. A charging section 3 of a power source apparatus 1 has a determination means 33 for determining whether the charging quantity amounts to a predetermined level according to a power generation timing of the piezoelectric device. Thus, this apparatus efficiently monitors and determines the charging quantity according to increasing timings and is therefore charged with a larger power without a wasteful consumption for monitor or determination.
    • 包括压电装置的常规电源装置具有发电量小的问题。 在使用用作触发电路的恒压二极管来确定充电量的情况下,与压电装置产生的功率量相比,触发电路一直操作使功耗大到不可忽视的程度。 电源装置1的充电部3具有根据压电装置的发电定时来判断充电量是否达到预定电平的判定装置33。 因此,该装置根据增加的定时有效地监视和确定充电量,并且因此以较大的功率充电,而不会浪费用于监视或确定的消耗。
