Patent ID: 7396121

Claim:
An ink jet printer comprising: a first transport roller to be driven in a sheet feed direction in which a recording sheet is to be fed; plural first driven rollers configured to press the recording sheet against the first transport roller to nip the recording sheet therebetween; a second transport roller to be driven in the sheet feed direction at location downstream of the first transport roller in the sheet feed direction; plural second driven rollers configured to press the recording sheet against the second transport roller to nip the recording sheet therebetween; and an ink head configured to jet ink against the recording sheet while moving in a direction orthogonal to the sheet feed direction between the first transport roller and the second transport roller in the sheet feed direction, the jetting of ink against the recording sheet by the ink head being continued even after passage of a trailing edge of the recording sheet between the first transport roller and the first driven rollers, wherein: biasing members, each configured to exert a biasing force on a respective one of the plural first driven rollers in such a direction as to press the respective one of the plural first driven roller against the first transport roller, are disposed at different positions in the direction orthogonal to the sheet feed direction; and nip points between the first transport roller and the first driven rollers are located at respective positions in the sheet feed direction in such a manner as to take respective positions in the direction orthogonal to the sheet feed direction which are substantially symmetric with respect to a center line of the recording sheet parallel with the sheet feed direction.
