Patent number: 9770928Abstract: A printing apparatus is provided and includes cover members for covering at least a portion of a conveyance path for conveying a medium. The cover members are configured such that at least a portion of a part covering a conveyance path is able to expand and contract. Therefore, if necessary, it is possible to expand or contract the area of the cover members covering the conveyance path. On the occasion of setting the medium or when a jam has occurred, it is possible to contract the cover members in the conveyance direction of the medium. Also, even if the cover members move once from the state where they cover the conveyance path, it is possible to easily return the cover members to their original positions, and it is possible to easily return the cover members to the state where they cover a portion of the conveyance path.Type: GrantFiled: May 12, 2016Date of Patent: September 26, 2017Assignee: MIMAKI ENGINEERING CO., LTD.Inventors: Ryuta Harayama, Shunsuke Akuta, Katsutoshi Yamabe, Tomonori Amari, Eiji Miyashita
