Abstract
PURPOSE: To enable analog time indication without providing train wheel, etc. by using time signal to drive second-minute-hour elements of liquid crystal, etc. installed on 60-equally-devided circular periphery of display plate.
CONSTITUTION: Second elements 2..., minute elements 3..., and hour elements 4... made of light emitting diodes, etc. are provided on 60-equally-devided circular periphery of display plate 1. These elements 2..., 3..., 4... are driven by time signals that are formed by deviding process of crystal oscillator output. This mechanism, together with time indicators 5... on the dial plate 1, provides clock or watch that indicates analog time, without using train wheel, etc.
