US 2002/0159773 A1 · Driving mechanism

Abstract

An object of the invention is to provide a driving mechanism of a simple structure capable of preventing transmission of vibration generated by a rotative driving source such as a motor to an object to be driven such as a camera. Driving the motor to rotate its output shaft causes a rotating member to rotate. Concurrently an elastic roller rotates and transmits a driving force to a force point section of a driven member. During such operation, since slight vibration generated by the motor is damped absorbed in the roller, the vibration transmitted to the driven member becomes substantially slighter. When the driving force is applied to a force point section the force point section is caused to swing, and concurrently the camera fixed to an action point section is caused to swing. Since transmission of vibration generated by the motor can be prevented, images taken by the camera will not shake.

Dependent claims

A driving mechanism for transmitting a rotative force of a rotative driving source for driving an object to be driven, comprising:

a supporting base;
a rotating member that rotates relative to a rotation of an output shaft of the rotative driving source;
an elastic body unit located at a position of the rotating member which position is not on a rotational axial line thereof;
a driven member provided with a force point section with which the elastic body unit contacts, an action point section to which the object to be driven is attached, and a fulcrum section;
and
a supporting shaft unit for connecting the fulcrum section of the driven member with the supporting base so that the driven member can rotate.
