Abstract
A carriage aligning apparatus in an ink-jet printer having a guide bar and a carriage disposed to slide along the guide bar to be across a paper transferring direction includes a spherical bearing rotatably connected to the carriage, a shaft hole formed eccentrically with respect to a center of an outer circumference of the spherical bearing to receive the guide bar, and a position deciding unit controlling a position of the spherical bearing with respect to the carriage and aligning the carriage with regard to the guide bar.
Claims38
A carriage aligning apparatus in an ink-jet printer including a guide bar and a carriage disposed to slide along the guide bar crossing a paper transferring direction, comprising:
- a spherical bearing rotatably connected to the carriage, having a shaft hole formed eccentrically with respect to a common center of an outer circumference of the spherical bearing to rotatably receive the guide bar, and controlling the carriage to be aligned with the guide bar;
- and
- a position deciding member maintaining a position of the spherical bearing with respect to the carriage when the carriage is aligned with the guide bar in response to a movement of the spherical bearing.
An apparatus in an ink-jet printer having a frame mounted with a mechanism transferring paper in a paper transferring direction, a guide bar fixedly mounted on the frame and disposed across the paper transferring direction, and a carriage mounted with a printing head and slidably coupled to the guide bar to move along the guide bar, comprising:
- a carriage aligning unit disposed between the guide bar and the carriage to control the carriage to move toward and away from the guide bar.
An apparatus in an ink-jet printer having a frame mounted with a mechanism transferring paper in a paper transferring direction, a guide bar fixedly mounted on the frame and disposed across the paper transferring direction, and a carriage mounted with a printing head and slidably coupled to the guide bar to move along the guide bar, the apparatus comprising:
- a support formed on the carriage, having a common axis, a bearing connection portion, and a connection hole having the common axis and formed in the bearing connection portion to receive the guide bar;
- a bearing having a first side corresponding to the bearing connection portion, a second side, a shaft hole formed between the first side and the second side to communicate with the connection hole and having a shaft axis eccentric to the common axis by a predetermined distance to receive the guide bar, and a plurality of grooves formed on the second side around the common axis;
- and
- a position holding member detachably mounted on the carriage to be coupled to one of the grooves when the bearing is disposed within the bearing connection portion.
A method in an inkjet printer having a guide bar, a carriage moving along the guide bar, a bearing coupled between the guide bar and carriage to move the carriage with respect to the guide bar, and an eccentric hole formed in the bearing about a shaft axis eccentric to a common axis passing a center of the bearing to receive the guide bar disposed eccentric to the common axis, the method comprising:
- rotating the bearing about the common axis;
- and
- moving the carriage toward and away from the guide bar in response to a rotation of the bearing.
