Abstract:
1. An inkjet printer comprising: a printer main body which performs printing on a printing medium; a support body which supports the printer main body; a medium feeding means for feeding out the printing medium in an elongated sheet shape toward the printer main body; a medium winding means for winding the printing medium which has been fed out by the medium feeding means and has been printed in the printer main body; a feeding side tension applying means which applies a tension to the printing medium which has been fed out by the medium feeding means and before reaching to the printer main body; and a winding side tension applying means which applies a tension to the printing medium which is fed out from the printer main body and before being wound by the medium winding means; wherein the medium feeding means and the feeding side tension applying means are mounted on the support body on one side in a feeding direction of the printing medium with respect to the printer main body; wherein the medium winding means and the winding side tension applying means are mounted on the support body on the other side with respect to the printer main body; wherein the feeding side tension applying means is provided with a feeding side tension adjustment mechanism which is structured of; wherein the tension applied to the printing medium by the feeding side tension applying means can be adjusted by using a torque acting on the feeding side ballast arm by the feeding side ballast member; wherein the winding side tension applying means is provided with a winding side tension adjustment mechanism which is structured of; wherein the tension applied to the printing medium by the winding side tension applying means can be adjusted by using a torque acting on the winding side ballast arm by the winding side ballast member; and wherein the feeding side tension adjustment mechanism and the winding side tension adjustment mechanism are provided so as to displace from each other in the direction perpendicular to the feeding direction of the printing medium and are partly overlapped with each other in a side view where the feeding direction is a front direction.
