Abstract
A case member and a resilient supporting member are removably coupled to each other. The case member has a mounting portion mounted on a traveling member, which includes a carriage of a printing apparatus. The supporting member includes first and second portions which are formed integrally from a leaf spring material, and can be deformed elastically. A printing hammer, a bearing member supporting the hammer, a solenoid coil member for driving the hammer, a spring member used to return the hammer, a hammer socket receiving an impact from the hammer, and a shock absorbing rubber plate are coupled together and held between the case member and the supporting member. As the printing hammer moves to its return position, it abuts against the hammer socket, thereby moving it in a returning direction. Returning energy received from the hammer is transmitted to the first portion of the supporting member through the rubber plate, to be absorbed between the rubber plate and the supporting member, on the one side, and to the second portion of the supporting member, which is directly in contact with the hammer socket, on the other side.
