Abstract
This apparatus has a liquid jet head for ejecting liquid drops from nozzle openings of a nozzle plate, a scanning mechanism for scanning the head in the head scanning direction, a feed mechanism for feeding an object to be processed in the direction perpendicular to the head scanning direction, an absorption member arranged in the area, which is on the rear side of the object during processing and opposite to the head, for absorbing liquid drops ejected in the area outside the object, and a potential difference generation unit for generating a potential difference between at least one of the absorption member and the member neighboring the absorption member and the nozzle plate. According to this apparatus, liquid drops ejected from the head into the area outside the object can be prevented from misting.
Claims54
A liquid jet apparatus comprising:
- a liquid jet head having a nozzle plate with a nozzle opening, said liquid jet head being configured to eject liquid drops from said nozzle opening by changing pressure of liquid in a pressure chamber interconnecting to said nozzle opening,
- a scanning mechanism configured to scan said liquid jet head in a head scanning direction,
- a feed mechanism configured to feed an object to be processed, to which liquid drops ejected from said liquid jet head are applied, in a feed direction perpendicular to said head scanning direction,
- an absorption member arranged in an area, which is on a rear side of said object to be processed under processing and opposite to said liquid jet head, and configured to absorb liquid drops ejected into an area outside said object to be processed, and
- a potential difference generation unit configured to generate a potential difference between at least one of said absorption member and a member neighboring said absorption member and said nozzle plate.
