    • A cordless instrument (20, 40) detachable from a charger (10, 30, 31) is attached to the charger (10, 30, 31), and is charged. A first storage part (12, 33) chargeable from a direct current source (11, 32) included in the charger (10, 30, 31), a first charge and discharge control circuit (13, 50) to control charge and discharge of the first storage part (12, 33), a second storage part (21, 43) included in the cordless instrument (20, 40), and a second charge and discharge control circuit (22, 45) to control charge and discharge of the second storage part (21, 43) are provided. Further, a third storage part (28) chargeable from the direct current source (11, 32) may be provided. Also to the cordless instrument (20, 40), a fourth storage part (44) may be provided. Upon attaching the cordless instrument, the second storage part (21, 43) is charged at least from the first storage part (12, 33). In comparison with charging time to conventional secondary batteries, it is capable of rapid charge, long life use, resulting in such merits as to realize the compact size of a charger and low cost.
    • 从充电器(10,30,31)可拆卸的无绳乐器(20,40)附接到充电器(10,30,31),并且被充电。 包括在充电器(10,30,31)中的从直流电源(11,32)充电的第一存储部件(12,33),用于控制充电器(10,30,31)中的充电和放电的第一充放电控制电路 第一存储部(12,33),包括在无绳乐器(20,40)中的第二存储部(21,43),以及第二充放电控制电路(22,45),用于控制 第二存储部(21,43)。 此外,可以提供可从直流源(11,32)充电的第三存储部(28)。 而且,对于无绳仪器(20,40),也可以设置第四存储部件(44)。 在连接无绳乐器时,至少从第一存储部分(12,33)充电第二存储部分(21,43)。 与常规二次电池的充电时间相比,它能够快速充电,使用寿命长,从而实现了充电器的紧凑尺寸和低成本的优点。
