恐れはないが、高価な構成とならざるを得なかった。In the prior art shown in FIGS. 6, 7 and 8, when the printing apparatus is operating, both ends of the belt conveying device 1 are fixed and are held in a prescribed position. However, when the belt is pulled out mainly for cleaning or replacement, the rear frame 3
It is supported in a cantilever manner by the holding stay 2 fixed to. When the belt conveying device 1 is pulled out in this state, the belt conveying device 1 falls due to the deformation of the holding stay 2 and the deformation of the rear frame 3 supporting the holding stay 2, and the belt (not shown) and the belt conveying device are removed. There was a problem that it was damaged. Further, by repeatedly deforming the holding stay 2 and the rear frame 3, distortion occurs in each part, and a prescribed position is displaced when the printing apparatus is in operation, which causes a problem of print quality deterioration. Furthermore, when the belt conveyor is largely depressed, there is a problem that operability and maintainability deteriorate. The configuration in which the moving frame that surrounds the entire belt transport device is provided does not have a risk of damaging the belt transport device, but it is inevitably an expensive configuration.
