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.
Claims24
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 adapted to be supported on said carriage, said plate supporting an ink jet head;
- a pin formed on said carriage, said plate being pivotable about said pin;
- 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 when said cam surface contacts said at least one 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 plate adapted to be supported on said carriage, said plate supporting an ink jet head;
- and
- a nozzle position adjusting member pivotably mounted on said carriage for urging said plate in a sheet feed direction, said sheet feed direction being perpendicular to said scanning direction.
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 adapted to be supported on said carriage, said first plate and said second plate supporting an 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 angle adjusting member pivotably mounted on said carriage for urging said first plate in said scanning direction 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 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, said sheet feed direction being perpendicular to said scanning direction.
