The solar cell 10 is attached to the upper surface of the outer periphery of the dial 15 in parallel with the front cover 13. FIG. 5 shows a pattern of the transparent electrode 17 formed on the dial 15 by vapor deposition. Figure 6 is the − of Figure 5.
A cross-sectional view is shown. 17a is a solar cell contact portion of the transparent electrode 17, 17c is a movement terminal contact portion of the transparent electrode 17, and 17b is a solar cell contact portion 17a of the transparent electrode 17 and a movement terminal contact portion 17.
This is a connection part that connects c. Note that six solar cells 10 are connected in series, with two solar cells arranged in parallel forming one set. Movement 14
is driven by a step motor etc.
It has a power supply terminal 14a which serves both as a terminal for a circuit directly input to the motor and as a terminal for a charging circuit for a secondary battery for driving this motor. Note that transparent electrode 1
Indium oxide or the like is used as the material 7, and depending on the processing method, it can serve both as wiring and a resistor.
Therefore, a transparent electrode can be used as a substitute for the overcurrent prevention resistor provided within the movement 14 or the like.
このように、太陽電池セル１０とムーブメント

ことができる。 In this way, since the solar cell 10 and the power terminal 14a of the movement 14 are connected by the transparent electrode 17, the wiring pattern is not visible from the outside as in the conventional case, and the appearance is improved. Since the transparent electrode 17 only needs to be attached to the surface of the dial 15, there is no need to provide a hole for wiring as in the conventional case, and processing is easy, and electrical connection is easier than when using lead wires. become. moreover,
By using the transparent electrode 17 as a resistor, the overcurrent prevention resistor can be omitted, and the number of parts can be reduced.
