Abstract
An impact dot printer designed to reduce noise, including a first cover, a second cover, and an overlap portion therebetween. The first cover is located above a print section, and may include sound wave reflecting plates, sheet guide plates, and a sound absorbing member, each reflecting plate, each sheet guide plate, and the sound absorbing member being arranged close to the print section. The second cover is rotatable relative to the first cover and forms a printed sheet discharge path together with the first cover. The second cover also has sound wave reflecting plates and sheet guide plates. Each sheet guide plate is designed to be projected farther from the associated cover than the corresponding reflecting plate on said cover. The distance between adjacent sheet guide plates is made smaller than the width of the smallest sheet to be used in the printer. The overlap portion between the first and second covers is arranged so that essentially no opening is provided between the first and second covers when viewed from the top or side.
