必要があり、そのために設置場所を選択する必要
がある。ところが、設置場所の適否の判断は使用
者には難しいものであつた。 A watch using a solar cell needs to be irradiated with light of a predetermined illuminance or higher for a certain period of time, and if the amount of light and the irradiation time are insufficient, the electromotive force of the solar cell will be insufficient and the watch will stop. In other words, it is necessary for solar cells to obtain an electromotive force from external light that is greater than the sum of the power consumption of the clock's drive circuit and the power required to charge the secondary battery, and for this purpose it is necessary to select the installation location. be. However, it has been difficult for users to judge whether the installation location is appropriate.
そこで本発明は、設置場所の選択に当つて、適

陽電池時計を提供するものである。 SUMMARY OF THE INVENTION The present invention provides a solar cell watch that, when selecting an installation location, can determine with an extremely simple configuration and operation whether or not an appropriate amount of light will be irradiated for a specified period of time or more.
以下本発明の一実施例を図面に基づいて説明す

ライドして抵抗値が調整される。 An embodiment of the present invention will be described below based on the drawings. E 1 is a solar cell, E 2 is a secondary battery, and A is an integrated circuit that constitutes a clock drive circuit and drives a motor M. r is a resistor, D is a diode, S is a manual switch, and R is a variable resistor. P is an irradiation time setting device, and by sliding the knob B in the vertical direction, the tap T of the variable resistor R slides to adjust the resistance value.
以上の構成において、時計の設置場所の選択に
当つては、つまみＢによつて、その設置場所にお
ける一日の平均的な光の照射時間を設定する。太
陽電池の起電力は光量と照射時間との積によつて
決定され、照射時間が長ければある程度光量が少

必要とするものである。そこで設定された照射時

射時間が可変抵抗Ｒの抵抗値として設定される。 In the above configuration, when selecting the location where the clock is installed, the knob B is used to set the average daily light irradiation time at that location. The electromotive force of a solar cell is determined by the product of the amount of light and the irradiation time; if the irradiation time is long, the amount of light may be small to some extent, and if the irradiation time is short, a large amount of light is required. Then, slide the tap T so that the longer the set irradiation time, the greater the resistance value of the variable resistor R. That is, the irradiation time is set as the resistance value of the variable resistor R.
そこで、本時計装置を設置して、スイツチＳを
図示の状態にし、駆動回路Ａと可変抵抗Ｒとを並

る。 Therefore, the present clock device is installed, the switch S is set to the state shown in the figure, and the drive circuit A and the variable resistor R are connected in parallel and connected to the solar cell E1 . Therefore,
The electromotive force of the solar cell E1 is consumed by the drive circuit A and the variable resistor R. If the product of the light amount at this installation location and the above irradiation time is sufficient,
The variable resistor R is set so that the drive circuit A is operated by the electromotive force of the solar cell E1 at this time and the motor M is normally driven. Recognize. Further, it can be seen that the drive circuit A does not operate in a place where the amount of light is insufficient, and the motor M does not drive, making the place unsuitable for installation.

い。 After selecting the appropriate installation location in this way,
Switch switch S, connect secondary battery E 2 ,
This is used as a power source for drive circuit A. Normal time,
Secondary battery E 2 is sequentially charged by solar battery E 1 via resistor r and diode D. When the secondary battery E 2 discharges beyond a certain level, the solar battery E 1
As a result, the secondary battery E2 is charged and the operation of the drive circuit A is compensated, so that the clock does not stop.
なお、モータＭとしてパルモータを用いた場合
には、消費電流が一定でないので、可変抵抗Ｒに
並列にコンデンサを接続することによつて上記と
同様の機能を持たせることができる。 Note that when a pulse motor is used as the motor M, the current consumption is not constant, so by connecting a capacitor in parallel to the variable resistor R, the same function as described above can be provided.

に簡単である。 As described above, according to the present invention, the resistance value of the variable resistor is set according to the irradiation time at the installation location,
Since this is connected in parallel to the clock's drive circuit using a switch and connected to the solar battery, it is possible to immediately determine whether or not the amount of light at the installation location is sufficient based on whether or not the clock is working. It is also very simple.
