Title:
ROTARY DECORATION MECHANISM
Document Type and Number:
Japanese Patent JP3247851
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To reduce electric power consumption, and obtain smooth rotary operation of a rotary decoration by intermittently rotating a decoration receiver by intermittent rotation of a step motor through flexible driving levers.
SOLUTION: A step motor 6 transmits this intermittent rotation to an output gear 10 through an intermediate gear 8 by reducing a speed since a rotor 6a intermittently rotates every one step when this is actuated, and intermittently rotates an output shaft 12 every one step by intermittent rotation of the output gear 10. Therefore, a main body part 26a of a driving member 26 is also intermittently rotated every one step, and driving levers 26b and 26c are bent and deflected by engaging its release end or a midway part with the driving directional upper edge or an inside surface of slits 16b and 16c. A decoration receiver 16 is rotated by force stored in the driving levers 26b and 26c, and is sent forward more than the stopping main body part 26a, and as a result, a rotary decoration 24 can be smoothly rotated.
