ABSTRACT:
An impact receiving structure for an impact type printing mechanism, in which vibration members for guiding along branched paths the vibration of an impact receiving face member, which is vibrated by the striking energy of a printing hammer, are provided at other positions than the printing face of a platen or at the inside of a type drum in the impact type printing mechanism, and in which elastic vibration absorbing materials are packed in close contact with the vibration members, so that noise attendant with the printing hammer impact can be effectively attenuated.
