Abstract

PURPOSE:To rationalize the constitution by specifying the location of cells and elements. CONSTITUTION:At the upper side center of the circuit board 10, the fitting notch 14 in common use with positioning, and two fitting holes 11, 12 and one positioning hole 13 are located in a row, and the battery 171 is located around the center of the circuit board 10. The watch IC 18 is located in the region 17 among the four regions split with the two straight lines 15 and 16 around the battery 171 and the watch circuit is constituted in the region 20. The crystal oscillator 21, trimmer capacitor 22, temperature compensation capacitor 23, chip capacitors 24 to 26, resistor 27, and transistor 28 are located as shown in the diagram. Thus, other watch elements are all located at the region adjacent to the watch IC 18, the wiring is saved, and the calculator IC 30 can be located at the regon 29, the calculator booster IC 33 is at the region 32, and the booster chip capacitor 34 can be located to give various composite functions.
