Abstract
A rotating shaft coupling has a plurality of rotating-shaft-coupling-members. One of the rotating-shaft-coupling-members is multi-layered by a coupler connecting a shaft thereto, an elastic body and an inertia body which has a mass activating a torsion load in a rotating direction when the elastic body is rotating. A plurality of the rotating-shaft-coupling-members are assembled into the rotating shaft coupling. By this construction, transmission of the vibration from a motor side to a driven side can be effectively suppressed.
Claims5
An image scanning apparatus comprising:
- (a) a document table for putting a document on;
- (b) a carriage having a scanning module for reading an image data of the document by scanning the document;
- (c) a driving mechanism for driving said carriage;
- and
- (d) a rotating shaft coupling assembled in said driving mechanism;
- wherein said rotating shaft coupling has a plurality of rotating-shaft-coupling-members, one of said rotating-shaft-coupling-members being multi-layered by a coupler connecting a shaft thereto, an elastic body and an inertia body which has a mass activating a torsion load in a rotating direction when said elastic body is rotating, and a plurality of said rotating-shaft-coupling-members are assembled into said rotating shaft coupling,
- wherein each of said rotating-shaft-coupling members is comprised so that said coupler, said elastic body and said inertia body are multi-layered.
