4.内部回路
揺動玩具100の内部には、図6に示す時計用IC40が設置されている。時計用ICはソーラバッテリ42を電源とし、ソーラバッテリ42に蓄電された電力によって水晶振動子41が作動する。時計用IC40には前記電磁コイル33が接続され、この電磁コイル33は時計用IC40からの電圧パルスによって励磁される。この場合、電磁コイル33の両端には時計用ICから交互に電圧パルスが印加される。その結果、電磁コイル33において前記永久磁石32に対峙する部分がN極となったりS極となったりし、この極性の切替えによって振り子30は左右に動作する。
なお、電磁コイル33には直列に抵抗43が設けられている。抵抗43を設けた理由は次の通りである。すなわち、電磁コイル33は電流の流れ始めには抵抗値が小さく、ソーラバッテリ42の蓄電の始めにおいて電力が即座に消費されてしまい振り子30が揺動しない場合があり、このような事態を防止するためである。
4). Internal Circuit Inside the swinging toy 100, a timepiece IC 40 shown in FIG. The timepiece IC uses the solar battery 42 as a power source, and the crystal unit 41 is operated by the electric power stored in the solar battery 42. The timepiece IC 40 is connected to the electromagnetic coil 33, and the electromagnetic coil 33 is excited by a voltage pulse from the timepiece IC 40. In this case, voltage pulses are alternately applied to both ends of the electromagnetic coil 33 from the timepiece IC. As a result, the portion of the electromagnetic coil 33 that faces the permanent magnet 32 becomes an N-pole or an S-pole, and the pendulum 30 moves left and right by switching the polarity.
The electromagnetic coil 33 is provided with a resistor 43 in series. The reason why the resistor 43 is provided is as follows. That is, the electromagnetic coil 33 has a small resistance value at the beginning of current flow, and power may be consumed immediately at the beginning of power storage in the solar battery 42, and the pendulum 30 may not swing. This situation is prevented. Because.

5.動作
揺動玩具100は明るい場所に置かれると、ソーラバッテリ42が蓄電され、その蓄電した電力によって時計用IC40から電圧パルスが出力され、電磁コイル33が励磁される。この場合、電磁コイル33は極性を切り替え、その電磁力によって振り子30ひいては頭部2bが左右に揺動する。
5. Operation When the oscillating toy 100 is placed in a bright place, the solar battery 42 is stored, voltage pulses are output from the watch IC 40 by the stored power, and the electromagnetic coil 33 is excited. In this case, the polarity of the electromagnetic coil 33 is switched, and the pendulum 30 and thus the head 2b swing left and right by the electromagnetic force.
