Title:
POINTER TYPE ELECTRONIC TIMEPIECE
Document Type and Number:
Japanese Patent JP2002082181
Kind Code:
A
Abstract:

To provide a pointer type electronic timepiece, capable of reducing size and thickness by improving the structure of mechanical parts which are constituted inside the time piece.

In the pointer type electronic timepiece, a rotary bob 25 is supported by a first train wheel receiver 3 similar to a train wheel for a timepiece and so fixing with a screw only the first train wheel receiver 3 to a ground plate 2 is sufficient, which results in a small number of screw fixing locations. The first train wheel receiver 3 is reinforced by a second train wheel receiver 6 layered and fixed on it. An inner member 92 of a ball bearing 90 fixed with a screw for fixing the rotary bob on the first train wheel receiver 3 side and the hole, where the screw is fixed is a blind hole 970, so that chips and grinding powder will not fly in movement. Nevertheless, oil injection in a tenon part 541 upside the second wheel 54 is possible, if this is prior to covering the second train wheel receiver 6, after assembling.
