Abstract
A head position adjustment mechanism includes two plates mounted so as to be displaceable in a scanning direction and in a sheet feed direction. The two plates can be adjusted independently in a scanning direction by angle adjusting levers that pivot the plates about reference pins. At least one plate can be adjusted in the sheet feed direction by a nozzle positioning adjusting lever that actuates a cam positioned to urge the plate in the sheet feed direction while the plate is guided by a reference pin.
Claims18
A head position adjusting mechanism for an ink jet printer, comprising:
- a carriage disposed in said ink jet printer, said carriage moveable in a scanning direction;
- a plate supported on said carriage, said plate supporting an ink jet head;
- a pin formed on said carriage, said plate being pivotable about said pin;
- a spring member disposed on said carriage to urge said plate against said carriage in said scanning direction and in a sheet feed direction, said sheet feed direction being substantially perpendicular to said scanning direction;
- and
- an angle adjusting member pivotably mounted on said carriage, said angle adjusting member having a cam surface for urging said plate in said scanning direction and opposing the urging of said spring member when said cam surface contacts said plate to pivot said plate about said pin.
A head position adjusting mechanism for an ink jet printer, comprising:
- a carriage disposed in said ink jet printer, said carriage moveable in a scanning direction;
- a first plate and a second plate supported on said carriage, said first plate and said second plate each supporting a respective ink jet head;
- a first pin and a second pin formed on said carriage, said first plate being pivotable about said first pin, and said second plate being pivotable about said second pin;
- a first spring member and a second spring member disposed on said carriage to urge said first plate and said second plate, respectively, against said carriage in said scanning direction and in a sheet feed direction, said sheet feed direction being substantially perpendicular to said scanning direction;
- a first angle adjusting member pivotably mounted on said carriage for urging said first plate in said scanning direction opposing the urging of said first spring member when said first angle adjusting member contacts said first plate to pivot said first plate about said first pin;
- a second angle adjusting member pivotably mounted on said carriage for urging said second plate in a scanning direction opposing the urging of said second spring member when said second angle adjusting member contacts said second plate to pivot said second plate about said second pin;
- a nozzle position adjusting member pivotably mounted on said carriage for urging one of said first and second plates in a sheet feed direction opposing the urging of at least one of said spring members, said sheet feed direction being perpendicular to said scanning direction.
