Abstract
Provided is a liquid ejecting device that includes an endless transporting belt that is stretched over a plurality of rollers and transports a medium in a transport direction by rotating while supporting the medium at a support surface that is a surface on an opposite side from a contact surface with the rollers, and a liquid ejecting unit that ejects a liquid onto the medium supported by the support surface. At the contact surface, recesses and protrusions are regularly formed in the circumferential direction of the transporting belt.
Claims13
A liquid ejecting device comprising:
- an endless transporting belt stretched over a plurality of rollers and configured to transport a medium in a transport direction by rotating while supporting the medium at a support surface that is a surface on an opposite side from a contact surface with the rollers;
- and
- a liquid ejecting unit configured to eject a liquid onto the medium supported by the support surface, wherein:
- recesses and protrusions are regularly formed at the contact surface in a circumferential direction of the transporting belt, and
- the recesses and protrusions include, as recessed portions, a plurality of first direction grooves extending along a first direction that intersects the circumferential direction and a width direction, of the transporting belt, intersecting the circumferential direction, and a plurality of second direction grooves extending along a second direction that intersects all of the circumferential direction, the width direction, and the first direction, and include, as protruding portions, each of regions surrounded by the first direction grooves and the second direction grooves forming the recessed portions.
