  • Patent number: 11813872
    Abstract: A recording apparatus includes a discard absorbing member (first absorbing member) that absorbs a liquid discarded from a discharge head to an outer side of an end portion of a medium supported by a support section as a waste liquid. Further, the recording apparatus includes: a cap which is an example of a waste liquid receiving section that receives the liquid ejected from the discharge head as a waste liquid; a waste liquid absorbing member (second absorbing member) that absorbs the waste liquid sent from the cap; and a waste liquid box (accommodating section) that holds the waste liquid absorbing member. The discard absorbing member and the waste liquid absorbing member 50A are coupled to each other such that the waste liquid can be delivered from the discard absorbing member to the waste liquid absorbing member.
