[Other Embodiments]
(1) In the wrinkle stretching portion 300 according to the first embodiment, the wrinkle stretching portion 300 has a latch structure for selectively adjusting the mounting angle of the rib 300L with respect to the support member 330 from a preset mounting angle. You may have. Specifically, a plurality of engaging holes are provided on the mounting surface 331 of the support member 330. The plurality of engaging holes are formed at substantially equal distances from the holes H at a constant pitch with each other. Then, at least one protruding portion that engages with the plurality of engaging holes is provided on the portion of the rib 300L that faces the mounting surface 331. With the rib 300L attached to the support member 330, the user rotates the rib 300L around the position where the hole H is provided as a rotation axis. Then, the rib 300L rotates while the protruding portion provided on the rib 300L engages with the plurality of engaging holes formed in the mounting surface 331. As a result, when the media M is conveyed with the rib 300L rotated at a predetermined rotation angle, the protruding portion provided on the rib 300L engages with a plurality of engaging holes formed on the mounting surface 331. The position is determined, and the wrinkles of the media M can be removed while maintaining the predetermined rotation angle. The number of the plurality of engaging holes can be determined by how much resolution the predetermined rotation angle is set to. For example, when the minimum unit of the rotation angle of the rib 300L is 30 °, the number of the plurality of engaging holes may be 360 ° / 30 ° = 12. Here, the resolution of the predetermined rotation angle also changes depending on the distance between each of the plurality of engaging holes and the hole H. For example, under the condition that the number of the plurality of engaging holes does not change, if the distance between each of the plurality of engaging holes and the hole H is short, each of the plurality of engaging holes and the hole The adjustment resolution is larger than when the distance to H is long. This is because the pitches of the plurality of engaging holes in the circumferential direction change. Therefore, the number of the plurality of engaging holes and the distance between each of the plurality of engaging holes and the holes H may be appropriately changed so as to obtain a desired resolution. As a result, the mounting state can be adjusted more efficiently. It should be noted that a plurality of protrusions may be provided on the mounting surface 331 of the support member 330 at positions at substantially equal distances from the hole H at a constant pitch. In this case, at least one engaging hole that engages with the plurality of protruding portions may be provided on the portion of the rib 300L that faces the mounting surface 331. With the above configuration, the mounting angles A of the plurality of first ribs 310 and the plurality of second ribs 320 can be adjusted more efficiently.
