Abstract

PURPOSE:To enable to judge if suitable amount of light required for charge is obtained, by setting the resistance value of a variable resistor according to illuminated time at an installation, and connecting it in parallel with the drive circuit of a clock through a switch. CONSTITUTION:In selecting the location of a clock, first average illumination time of light a day for the location is set with a knob B. This set is made as a resistance value of a variable resistor R. When the switch S is set as shown in Figure and a parallel connection of a drive circuit A and variable resistor R is connected to a solar cell E1, the drive circuit A is operated with an electromotive force of the solar cell E1 and a motor M is normally driven. Since the variable resistor R is set so that sufficient illuminating time can be obtained, it shows the location is suitable. If the location is set, then the switch S is selected for the secondary battery E2, which is used for the power supply for the drive circuit A.
