Description
【発明の詳細な説明】 本発明は太陽電池時計に関するものである。[Detailed description of the invention] The present invention relates to a solar cell watch.
従来、二次電池の代わりに大容量コンデンサを
用いたものでは、起動する際に大容量コンデンサ
が充電されるまでに５〜10時間かかり、この間時
計が動かせなかつた。つまり、新品の時計は箱詰
めされておりコンデンサの充電電荷が０になつて
いて、これが充電されるまで時間がかかるもので
あつた。 Conventionally, with devices that used large-capacity capacitors instead of secondary batteries, it took 5 to 10 hours for the large-capacity capacitor to charge when starting up, and the clock could not operate during this time. In other words, when a new watch is packed in a box, the charge on the capacitor is zero, and it takes time for the capacitor to be charged.
そこで本発明は大容量コンデンサを用いても最
初から直ちに時計を動作させることができる太陽
電池時計を提供するものである。 Therefore, the present invention provides a solar cell watch that can be operated immediately from the beginning even when using a large capacity capacitor.
以下本発明の一実施例を図面に基づいて説明す
る。太陽電池１にはダイオード２およびPNPト
ランジスタ３を介して大容量コンデンサ４を接続
してある。トランジスタ３のベース・エミツタ間
には抵抗５を接続してあり、トランジスタ３のベ
ースには時計回路６を接続してある。７は小容量
コンデンサである。 An embodiment of the present invention will be described below based on the drawings. A large capacitor 4 is connected to the solar cell 1 via a diode 2 and a PNP transistor 3. A resistor 5 is connected between the base and emitter of the transistor 3, and a clock circuit 6 is connected to the base of the transistor 3. 7 is a small capacitor.
以上の構成において、太陽電池１に起動力が生
じるとダイオード２および抵抗５を介して時計回
路６に電流が流れ、動作する。時計回路６に印加
される電圧が1.5Vを越えたとき、抵抗５の両端
電圧がトランジスタ３のスレツシヨルド電圧を越
えるように設定してある。したがつて時計回路６
を動作させるために必要な電流を越える起電力が
得られた場合は、この余剰電流は総てトランジス
タ３を介してコンデンサ４の充電に充てられる。
こうして余剰電流によつてコンデンサ４が充電さ
れる。 In the above configuration, when a starting force is generated in the solar cell 1, a current flows to the clock circuit 6 via the diode 2 and the resistor 5, and the clock circuit 6 operates. It is set so that the voltage across the resistor 5 exceeds the threshold voltage of the transistor 3 when the voltage applied to the clock circuit 6 exceeds 1.5V. Therefore, clock circuit 6
If an electromotive force exceeding the current required to operate is obtained, all of this surplus current is used to charge the capacitor 4 via the transistor 3.
In this way, the capacitor 4 is charged by the surplus current.
そして周囲が暗くなつて太陽電池から起電力が
得られなくなると、コンデンサ４からトランジス
タ３のコレクタ・ベースを介して電流が流れ時計
回路６を駆動する。 When the surroundings become dark and no electromotive force can be obtained from the solar cell, current flows from the capacitor 4 through the collector and base of the transistor 3 to drive the clock circuit 6.
なおコンデンサ７は必ずしも必要ではない。 Note that the capacitor 7 is not necessarily required.
このように本発明によれば、大容量コンデンサ
を使用しても起動時から直ちに時計を動作させる
ことができる。しかも余剰電流は総て大容量コン
デンサの充電に充てられる。 As described above, according to the present invention, even if a large capacity capacitor is used, the timepiece can be operated immediately after startup. Moreover, all surplus current is used to charge the large capacity capacitor.
