摘要： 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.

摘要： A printer wherein a drive roller of a pair of sheet discharge rollers is made of rubber and a driven roller of the pair of sheet discharge rollers is made of synthetic resin; the leading end of a sheet is guided so as to be abutted against the drive roller earlier than the driven roller; the sheet that is in the course of being discharged is guided by a sheet discharge tray so as to come in slidable contact with an edge portion that is on a print head side of a sheet discharge opening. As a result, the printer can provide satisfactory printing conditions quickly with a simple structure and reduce noise leaking from the sheet discharge opening.
