PLATEN PLATE AND LIQUID-DISCHARGING DEVICE

Title:

PLATEN PLATE AND LIQUID-DISCHARGING DEVICE

Document Type and Number:

WIPO Patent Application WO/2005/002862

Kind Code:

A1

Abstract:

A platen plate supporting an object to which liquid drops are discharged from each nozzle on the lower surface of a liquid-discharging head. The platen plate enables appropriate ink discharge while achieving flatness of the object and is capable of preventing defacement of the rear face of the object. The platen has ribs raised from a bottom face portion, extended in the transportation direction of recording paper, and arranged with predetermined intervals in the width direction of the recording paper. The platen is constructed so as to support, outside that area of the recording paper where ink drops discharged from each nozzle adhere, the recording paper rear face by top surfaces of the ribs, defining the distance between the recording paper and an ink-discharging surface. In the area where the ink drops discharged from each nozzle adhere, the ribs are formed such that their top surfaces are at a height where they do not come into contact with the rear face of the recording paper or, alternatively, the ribs themselves are not formed.
