Abstract
Provided is a liquid ejecting device including an ejecting unit configured to eject a liquid onto a medium, a detector configured to emit light toward an object opposing the ejecting unit and receive reflected light generated by reflection of the light thereby detecting information, and a cover portion including a cover that transmits the light and is disposed at a position to cover the detector. The cover portion is configured to move the cover so as to change a portion of the cover that covers the detector while the detector remains covered.

- a cover portion including a cover that transmits the light and is disposed at a position to cover the detector;
- a holding unit configured to hold the detector;
- a movement mechanism configured to cause the holding unit to reciprocate;
- and
- a protruding portion formed in a range in which the holding unit is configured to reciprocate, wherein
- the cover portion is configured to move the cover so as to change a portion of the cover that covers the detector while the detector remains covered,
- the cover unit includes a toothed gear at a position that allows for contact with the protruding portion when the holding unit reciprocates, the toothed gear moving together with the cover, and
- the toothed gear is configured so that a tooth of the toothed gear coming into contact with the protruding portion, as the holding unit reciprocates, moves the toothed gear.
