Patent ID: 7402828

Claim:
A liquid ejecting apparatus, comprising: a liquid ejecting head, operable to eject liquid toward a target medium; a light emitter, operable to emit light; a light receiver, 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, elongated in a first direction and disposed between the light emitter and the light receiver; a line pattern, provided with the transparent member so as to oppose the light emitter, and including light transmitting sections and light shielding sections which are alternately arranged in the first direction with a first pitch, wherein: each of the light transmitting sections is adapted to allow the light emitted from the light emitter to pass through; each of the light shielding sections is adapted to shield the light emitted from the light emitter; a width of each of the light transmitting sections in the first direction is reduced as being closer to a first end of the transparent member than a second end of the transparent member relative to a second direction perpendicular to the first direction; and the light receiver comprises: a substrate, elongated in the first direction; and a plurality of light receiving elements, arrayed on the substrate, the light receiving elements being arranged in a v-shape, wherein an apex of the v-shape is located proximate to the second end of the transparent member in a vicinity of a center of the transparent member relative to the first direction.
