摘要： The present invention relates to a liquid ejecting apparatus including: a movable head provided with a plurality of nozzles for ejecting a liquid; a carry unit for carrying a medium in a predetermined carrying direction; and a sensor for detecting an edge of the medium, the liquid ejecting apparatus controlling ejection of the liquid from the plurality of nozzles in accordance with a result of the detection of the sensor. In this liquid ejecting apparatus, the position, in the carrying direction, of the sensor is at the same position of or on an upstream side of a nozzle located most upstream in the carrying direction, of among the plurality of nozzles. In this way, it is possible to arrange the sensor for detecting the edge of the paper at the most suitable position, and to suppress waste of ink that is ejected from the nozzles.

摘要： A liquid ejecting head is operable to eject liquid toward a target medium. A light emitter is operable to emit light. A light receiver is adapted to receive the light emitted from the light emitter, and operable to output a signal in accordance with an amount of the received light, thereby detecting a position of the liquid ejecting head. A transparent member is disposed between the light emitter and the light receiver. A first line pattern is provided with the transparent member so as to oppose the light emitter, and includes first light transmitting sections and first light shielding sections which are alternately arranged in a first direction with a first pitch. A first actuator is operable to move either the light receiver or the transparent member in a second direction perpendicular to the first direction, thereby varying a distance between the transparent member and the light receiver.
