ABSTRACT:
In a motor driven type gong striking mechanism, the rotation of the main shaft of an electric motor is converted through a crank mechanism into the oscillation of a piston plate, a gong striking hammer is coupled through a spring to the piston plate so that the hammer is oscillated, and a gong is disposed in the range of oscillation of the hammer. Thus, as a result of the rotation of the motor, the hammer is oscillated to strike the gong provided in the stroke of the hammer.
