Abstract
A printer having a novel and improved mechanism for damping noise caused by the vibration of a motor of the printer is provided. The printer includes a frame having a hole therein, and a carriage mounted on the frame capable of moving relative thereto. A motor is mounted on the frame and operatively coupled to the carriage to reciprocate relative to the frame. A shock absorber, made of a resilient material, is interposed between the motor and the frame. The shock absorber has a stepped cylindrical shape, including a large diameter portion having an outer diameter less than the inner diameter of the frame hole, the frame having a thickness. The small diameter portion has a length greater than the thickness of the frame such that a portion of the small diameter portion projects beyond the frame to form a projecting end when the shock absorber is disposed within the hole. A screw is inserted into the shock absorber, the screw fixing the motor to the frame. A nut securing the screw is provided such that at least one of the screw and nut clamps the projected end of the small diameter portion of the shock absorber against the frame.
