Abstract: A printer includes an ejecting head that ejects ink, a glued belt including a support surface, a first fan and a second fan configured to blow air toward the support surface, and a facing portion facing a portion of the first fan and a portion of the second fan. The facing portion includes an opening that opens in the Z direction. The opening is located between the first fan and the second fan in the X direction when viewed in the Z direction. When a spacing in the X direction at a first position in the +Y direction is defined as the first spacing and a spacing in the X direction at a second position upstream of the first position in the +Y direction is defined as the second spacing, the second spacing is larger than the first spacing.
