Abstract
A printer includes a recording unit, a support portion, a negative pressure chamber, a first sectioned chamber, a second sectioned chamber, a first suction port, and a second suction port. The support portion includes a support face configured to support roller paper. The negative pressure chamber is disposed at an opposite side of the support portion from the recording unit side. The first and the second sectioned chamber include a first and a second bottom surface. The first and the second suction port cause an outside space and the negative pressure chamber to communicate with each other. An opening area of the second suction port is smaller than an opening area of a first suction portion. The second suction port disposed most upstream in the first sectioned chamber is disposed upstream, in the transport direction, of the first suction port disposed most upstream in the second sectioned chamber.
