Abstract

PURPOSE: To recognize the operation of a clock mechanism by the operation of an oscillator and using as a similar pendulum by operating the pendulum employing a signal of crystal oscillator of the clock mechanism.
CONSTITUTION: Two permanent magnets 7, 7' of S pole and N pole disposed on a pendulum body 2 so as to be placed at both sides of a coil member 4 and having a fixed spacing with respect to the coil member 4 are attracted or repelled by the coil member 4 due to magnetic force of the coil member 4 by receiving a signal from a high vibrating member such as crystal and forming the magnetic field of S pole and N pole alternately, and the pendulum body 2 is oscillated making an engaging piece 5 as a fulcrum. On an upper portion of the pendulum 2, an adjustable balance member 6 is provided to smoothen the oscillation of the pendulum body 2. By changing the width of two permanent magnets 7, 7', the oscillating width L of the pendulum body 2 is adjusted.
