摘要： In the present invention, a flat platen having a flat surface opposed to a print head is fixed to a platen supporting member by a fixing member, and a first impact absorbing member is disposed elastically between the platen and the platen supporting member. Accordingly, the propagation of vibration between the platen and the platen supporting member is prevented by a vibration absorbing action of the first impact absorbing member and vibrations in a vibration generation source are absorbed quickly. Thus, according to the present invention, a printing noise can be damped effectively.

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.
