Abstract
A sound reducing construction for shielding sound in a confined box, the box including a first plate component formed with a first open end portion and a second plate component formed with a second open end portion and accommodating therein a machine which generates the sound, the first plate component being movable with respect to the second plate component. The sound reducing construction comprises: a packing unit having one end fixed to the first open end portion of the first component and having another end portion in contact with the second open end portion when the first component is rested on the second component; and, the first and second open end portions providing stepped portions in conformance with each other. The first and second open end portions define two horizontally extending gaps whose vertical heights are different from each other and a vertically extending gap. The packing unit is positioned in one of the horizontally extending gap. The first and second component are cover and a main box which houses a printer therein.
