  • Patent number: 11897274
    Abstract: In the invention, pipes and the like are guided in parallel to a second horizontal direction according to collective movements of printing bar units while being stored and protected by a protecting/guiding member arranged outside and adjacent to a body frame. In this way, breakage of the pipes and the like during the collective movements of printing bar units is reliably prevented. Moreover, the pipes and the like stored in the protecting/guiding member move outside the body frame and are not present inside the body frame. As a result, a work space can be secured without being limited by the collective movements of the printing bar units to the maintenance space.
