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.

Description

[0001]The entire disclosure of Japanese Patent Application No: 2010-188278, filed Aug. 25, 2010 is expressly incorporated by reference herein.BACKGROUND[0002]1. Technical Field[0003]The present invention relates to a transport apparatus that transports a recording medium such as, for example, long paper or single sheet paper and a recording apparatus including the same.[0004]2. Related Art[0005]In the related art, among recording apparatuses that record a recording medium, there is an apparatus including a transport apparatus that transports the recorded recording medium toward an outlet (for example, JP-A-11-193158). That is, a transport apparatus described in JP-A-11-193158 is configured so as to transport the recording medium recorded by a recording unit at a recording position along a transport path by rotating both rollers constituting a transport roller pair in the state of being pinched therebetween by the transport roller pair that is disposed at a position more on a downstr...

AI Technical Summary

Benefits of technology

[0007]An advantage of some aspects of the invention is to provide a transport apparatus that can suppress the transport load relative to the recording medium passing through the transport path, and a recording apparatus that can suppress a decline in recording quality.

[0009]According to the configuration, in a case where the recording medium passing through the position, where the transport roller pair is disposed in the middle of the transport path, is a long recording medium, the transport roller pair does not pinch the recording medium therebetween. That is, when the length dimension along the transport direction of the recording medium is longer than the distance dimension between the position where the transport roller pair is disposed and the recording position more on the upstream side than the position, the transport roller pair does not pinch the long recording medium, whereby the transport load added to the recording medium by the transport roller pair is smaller than the case of the pinched state. Thus, the transport load relative to the recording medium passing through the transport path is suppressed, with the result that, for example, when the long recording medium passes through between both rollers of the transport roller pair, even in a case where the recording is concurrently performed in the recording position of the upstream side part in the recording medium, it is possible to contribute to the suppression of degradation of recording quality.

[0011]According to the configuration, when the transport roller pair does not pinch the long recording medium, at least one roller may be moved in a direction, in which at least one roller intersects the axial direction, and is separated from the transport path. Thus, it is possible to easily realize the configuration of the transport apparatus capable of suppressing the transport load.

[0013]According to the configuration, since the driven roller is easily moved in the direction intersecting the axial direction further than the driving roller, it is possible to easily configure the transport roller pair which does not pinch the long recording medium. Thus, it is possible to easily realize the transport apparatus capable of suppressing the transport load which is added to the long recording medium to be transported in this manner.

[0015]According to the configuration, in the pinched state in which the driven roller pinches the recording medium with the driving roller, it is possible to give the sufficient transport force to the recording medium to be transported. Thus, the transport apparatus can be compatible with the function of suppressing the transport load to be added to the long recording medium upon transporting the long recording medium and the function of giving another recording medium the necessary transport force upon transporting another recording medium other than the long recording medium.

Problems solved by technology

For this reason, in a case where a downstream side part of the recording medium is in the state of being pinched by the transport roller pair therebetween, when the upstream side part of the recording medium is still recorded by the recording unit in the recording position, there is a concern that disturbance of the recording relative of the upstream side part of the recording medium or the like is generated due to the generation of the transport load in the downstream side part of the recording medium, and the recording quality declines.
