Abstract: A printer includes a printer body, a hopper, an open-and-close cover, a paper support, and a support holder. The hopper pushes paper up while supporting the paper. The open-and-close cover is able to be opened from and closed toward the printer body. The paper support is provided in such a way as to be able to be housed inside and drawn away from the open-and-close cover, and is configured to support the paper by being drawn out. The support holder supports the paper, together with the hopper and the paper support. The support holder switches between an upright orientation for being housed into the printer body and a tilted orientation for supporting the paper together with the hopper and the paper support by the opening and closing of the open-and-close cover.
