Abstract
The liquid ejecting apparatus includes: a liquid jet head including a nozzle opening through which a liquid drop is ejected by changing pressure of a liquid in a pressure chamber interconnecting to the nozzle opening; a scanning mechanism including a carriage on which the liquid jet head is loaded, the scanning mechanism moves the liquid jet head in a head scanning direction together with the carriage; a case configured to contain the liquid jet head and the scanning mechanism; and a leading unit for leading a liquid drop, which is ejected from the liquid jet head and not applied to an article to be processed, in a given direction using an air stream generated in the case due to moving of the carriage.
Claims23
A liquid ejecting apparatus comprising:
- a liquid jet head including a nozzle opening through which a liquid drop is ejected by changing pressure of a liquid in a pressure chamber interconnecting to said nozzle opening;
- a scanning mechanism including a carriage on which said liquid jet head is loaded, said scanning mechanism moves said liquid jet head in a head scanning direction together with said carriage;
- a case configured to contain said liquid jet head and said scanning mechanism;
- leading means for leading a liquid drop, which is ejected from said liquid jet head and not applied to an article to be processed, in a given direction using an air stream generated in said case due to moving of said carriage;
- a feed mechanism for feeding said article to be processed in a feed direction perpendicular to said head scanning direction;
- and
- a support member arranged opposite to said liquid jet head, said support member supporting said article to be processed, which is fed by said feed mechanism, from a rear of said article so as to specify a position of said article to be processed with respect to said liquid jet head, wherein;
- said feed mechanism and said support member are contained in said case together with said liquid jet head and said scanning mechanism, and
- said leading means has an air hole passing through said support member.
A liquid ejecting apparatus comprising:
- a liquid jet head including a nozzle opening through which a liquid drop is ejected by changing pressure of a liquid in a pressure chamber interconnecting to said nozzle opening;
- a scanning mechanism including a carriage on which said liquid jet head is loaded, said scanning mechanism moves said liquid jet head in a head scanning direction together with said carriage;
- a case configured to contain said liquid jet head and said scanning mechanism;
- a static electricity charged member arranged on a surface parallel with said head scanning direction in said case;
- and
- a static electricity generation member installed on said carriage so as to make contact with said static electricity charged member when moving together with said carriage, and generate static electricity,
- wherein wind controlling plates projected in said head scanning direction are installed on lower portions of said front and rear faces of said carriage in said head scanning direction.
A liquid ejecting apparatus comprising:
- a liquid jet head including a nozzle opening through which a liquid drop is ejected by changing pressure of a liquid in a pressure chamber interconnecting to said nozzle opening;
- a scanning mechanism including a carriage on which said liquid jet head is loaded, said scanning mechanism moves said liquid jet head in a head scanning direction together with said carriage;
- and
- a case configured to contain said liquid jet head and said scanning mechanism;
- wherein:
- said case has left and right side walls arranged opposite to each other in said head scanning direction, and
- air holes capable of ventilating between an inside and an outside of said case are formed in said left and right side walls so that air comes in and goes out through the air holes due to pressure fluctuation caused in said case when said carriage moves in said head scanning direction.
