PURPOSE:To secure the assured conduction and at the same time to realize the miniaturization for a battery watch, by providing an elastic part where a conduction means touches a conduction pattern of a circuit block and the elastic part has the elasticity by its arc-shaped flexion. CONSTITUTION:A battery minus terminal 22 is set under a minute wheel 26, a quartz unit 23 and a battery 3. The terminal 22 functions as an elastic part. In other words, the battery 3 and a conduction part 22b have the spring force toward an arrow 32 and are deformed toward an arrow 34 respectively. On the other hand, a rotary substrate 21 and a conduction part 22a have the spring force toward an arrow 31 which is nearly right-angled to the substrate 21 and is substantially in the same direction as the part 22b. Thus an assured conduction is secured by forming the substrate 21 and a spring of the conduction part so that the direction of force is orthogonal to the deforming direction of the spring. At the same time, the miniaturization is possible for a battery watch. |
