Gap detector, liquid ejecting apparatus incorporating the same, and gap detecting method executed in the apparatus |
摘要 |
A gap detector is operable to detect a distance between a liquid ejecting head adapted to eject liquid toward a target medium and a platen adapted to support the target medium. A circular plate is adapted to be provided on a guide shaft which is rotated together with the rotary plate to selectively determine the distance as one of a plurality of distances. The circular plate has a plurality of flags formed on an outer periphery, each of which is associated with one of the distances. A sensor is disposed in the vicinity of the outer periphery of the circular plate and operable to output a signal indicative of a passage of each of the flags in accordance with the rotation of the circular plate. At least one of intervals between the flags in a circumferential direction of the circular plate is made different from the other.
