Title:
TIME PIECE
Document Type and Number:
Japanese Patent JPS5821585
Kind Code:
A
Abstract:

PURPOSE: To prevent oscillation of a time pointer by forming a dial plate of a magnet while a time pointer is formed of a magnetic material and vice versa.

CONSTITUTION: A minute pointer 18 and a timer pointer 19 are operated in contact with a dial plate 3. The minute pointer 18 is so arranged that only the tip thereof contacts the dial plate 3. The minute pointer 18 and the time pointer 19 are made of a magnet while the dial plate 3 made of a magnetic material. It is also possible that the former 18 and 19 is made of a magnetic material and the later 3 made of a magnet. Otherwise, in the dial plate 3, only the place where the minute pointer 18 is at rest may be made of either a magnet or magnetic material. This provides a time piece free of oscillation in the pointers without increase in the number of parts and difficulty in the assembly work.
