  Some of the ink jet printers described above are capable of recording on a relatively large size paper having a paper size of JIS A2 size. Since the carriage and carriage guide shaft of such an ink jet printer are relatively large, the carriage guide shaft may bend due to their own weight, and the gap between the recording head and the paper may change to reduce the recording accuracy.

  Therefore, it is conceivable to prevent the above-described bending by fixing the carriage guide shaft to the main frame together with a support shaft that supports the carriage guide shaft. However, there is a case where a torsion coil spring that presses the driven roller against the paper feed roller is attached to the main frame so as to urge the main frame in the reverse direction of conveyance. In such a case, the carriage guide shaft may bend together with the main frame due to the urging force, and the position of the recording head and the paper may change to reduce the recording accuracy. In addition, since the carriage guide shaft is fixed to the main frame, the parallelism between the carriage guide shaft and the platen depends on the component accuracy, and the gap between the recording head and the paper changes to reduce the recording accuracy. There is a case.

  The present invention has been made in view of the various problems as described above. The object of the present invention is to hardly affect the guide shaft of the carriage even if the main frame bends, and between the guide shaft and the ejection target medium.

It is characterized by being attached to the main frame of the apparatus. Thereby, even if the main frame is bent due to its own weight or the weight of the carriage, the bending is caused to pass through the support frame, so that the influence on the guide shaft can be almost eliminated.

  Further, the main frame is provided with a plurality of pressing members in the scanning direction of the carriage for pressing the driven roller, which is sandwiched between the conveyance rollers and conveys the ejection target medium, against the conveyance roller, It is characterized by being supported at both ends of the area where the pressing member is disposed. Thereby, even if the pressing member bends the main frame, the bending occurs between both ends of the support frame, so that the influence on the guide shaft can be substantially eliminated.

  Adjusting means for adjusting the parallelism of the guide shaft with respect to the ejected medium is provided, the support frame is supported so that both ends thereof can be fixed to the main frame, and one end is supported by a turning shaft, and the adjustment is performed. The means is characterized in that it makes contact with the other end of the support frame and pivots about one end. Thereby, even if the guide shaft has an intermediate support structure, the parallelism of the guide shaft can be adjusted.

  In order to achieve the above object, the liquid ejecting apparatus of the present invention is a liquid ejecting apparatus that ejects liquid onto a medium to be ejected, and includes the carriage guide shaft support mechanisms described above.
