POINTER INSTALLATION STRUCTURE, POINTER INSTALLATION CONTROLLER AND TIMEPIECE

摘要

PROBLEM TO BE SOLVED: To provide a pointer installation structure capable of accurately detecting a barycentric position of a pointer wheel, adjusting in good balance between a bias of a pointer barycenter and a bias of a pointer wheel barycenter, and attaching accurately the pointer to the pointer wheel, and a timepiece with the same.;SOLUTION: When a second pointer 2 is attached to a second pointer wheel 20, a first circular hole 21a of a reference hole of the second pointer wheel 20 is detected by a detection portion, thereby a rotating position of the second pointer wheel 20 is detected and the position of the barycenter G1 of the second pointer wheel 20 can be correctly detected. Consequently, even when the second pointer wheel 20 cannot be viewed from outside, the bias of the barycenter G1 of the second pointer wheel 20 and the bias of the barycenter Gs of the second pointer 2 can be adjusted in good balance by balancing out the barycenter G1 of the second pointer wheel 20 and the barycenter Gs of the second pointer 2, thereby the second pointer 2 can be attached in good accuracy to the second pointer wheel 20 by bringing the combined barycenter Gm of both close to the rotation center R of the second pointer wheel 20.;COPYRIGHT: (C)2010,JPO&INPIT
