Transport apparatus and recording apparatus

Abstract

A transport apparatus that transports a recording medium from an upstream side of a transport path to a downstream side thereof, including a transport roller pair which is disposed at a position more on a downstream side than a recording position where the recording medium is recorded in the transport path and transports the recording medium along the transport path, wherein, when the recording medium passes through between both rollers, in a case where a length dimension along the transport direction of the recording medium is longer than a distance dimension between a position where the transport roller pair is disposed and the recording position more on the upstream side than the position, both rollers do not pinch a long recording medium.

What is claimed is: 
     
         1 . A transport apparatus that transports a recording medium from an upstream side of a transport path to a downstream side thereof, comprising:
 a transport roller pair which is disposed at a position more on a downstream side than a recording position where the recording medium is recorded in the transport path, at least one of a roller situated at one surface side of the recording medium and a roller situated at the other surface side thereof comes into contact with the recording medium passing through the position and is rotated, whereby the transport roller pair transports the recording medium along the transport path,   wherein, when the recording medium passes through between both rollers, in a case where a length dimension along the transport direction of the recording medium is longer than a distance dimension between a position where the transport roller pair is disposed and the recording position more on the upstream side than the position, both rollers do not pinch a long recording medium.   
     
     
         2 . The transport apparatus according to  claim 1 ,
 wherein, when both rollers enter the non-pinched state, the transport roller pair is moved in a direction that is a direction in which at least one roller intersects an axial direction of the roller, and is separated from the transport path.   
     
     
         3 . The transport apparatus according to  claim 1 ,
 wherein the transport roller pair includes a driving roller which comes into contact with one surface side in the recording medium and is subjected to driving rotation, and a driven roller which comes into contact with the other surface side in the recording medium to be transported along with the driving rotation of the driving roller and is subjected to driven rotation, and when the driven roller transports the long recording medium, the transport roller pair is moved in the direction separated from the driving roller.   
     
     
         4 . The transport apparatus according to  claim 3 ,
 wherein a roller surface of the driven roller is formed by a member that has a frictional coefficient higher than that of a roller surface in the driving roller.   
     
     
         5 . A recording apparatus comprising:
 a recording unit that records a recording medium to be transported from an upstream side of a transport path to a downstream side thereof; and   the transport apparatus of  claim 1  that transports the recording medium recorded by the recording unit.
