Abstract
Abstract An ink jet recording apparatus for recording by infiltrated ink into a recording sheet or by fixing ink through evaporation of an ink solvent includes an ink jet recording head for ejecting ink onto the recording sheet at a recording area of the apparatus where the recording head is opposed to the recording sheet. The apparatus also includes a heating member extending both upstream and downstream with respect to the recording area and a conveying direction of the recording sheet. The heating member contacts the recording sheet to assist in the fixation of the ink. The apparatus further includes a press plate, disposed upstream of the recording area with respect to a conveying route of the recording sheet, for pressing the recording sheet against the heating member. The press plate has a portion opposed to the heating member and a plurality of slits spaced apart from each in a direction perpendicular to the conveying direction of the recording sheet. The apparatus also includes a conveying member for discharging the recording sheet from the printer. The conveying member is provided downstream of the recording area with respect to the conveying direction. The heating member extends to a position opposed to the conveying member.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
120 words
A printer comprising: ink jet recording means for recording on a recording sheet; means for providing a conveyance route for conveying the recording sheet through a recording area where said recording means is opposed to the recording sheet and records on the recording sheet, said means comprising a heating member for contacting the recording sheet to heat the recording sheet; and a press plate, disposed upstream of the recording area with respect to the conveying route, for pressing the recording sheet to said heating member, said press plate having a portion opposed to said heating member and a plurality of spaced apart slots spaced apart from each other in a direction perpendicular to a conveying direction of the recording sheet.
Claim 2
Dependent Claim
120 words
A printer comprising: ink jet recording means for recording on a recording sheet; means for providing a conveyance route for conveying the recording sheet through a recording area where said recording means is opposed to the recording sheet and records on the recording sheet, said means comprising a heating member for contacting the recording sheet to heat the recording sheet; and a press plate, disposed upstream of the recording area with respect to the conveying route, for pressing the recording sheet to said heating member, said press plate having a portion opposed to said heating member and a plurality of spaced apart slots spaced apart from each other in a direction perpendicular to a conveying direction of the recording sheet.
Claim 3
Dependent Claim
18 words
