Abstract
The ink discharge unit includes a biasing member. The biasing member is fixed to a fixing member immovably fitted to a carriage body that moves relative to a recording medium. The biasing member, while being thus fixed, biases an inkjet head in a direction illustrated with an arrow and in a direction illustrated with another arrow for position alignment of the inkjet head relative to the fixing member. The inkjet head, while being biased by the biasing member, is fixed to the fixing member. The fixing member has curved portions that regulate movements of the inkjet head in the directions illustrated with the arrows by way of contacts with the inkjet head.
Claims11
An ink discharge unit, comprising:
- an inkjet head that discharges an ink toward a recording medium;
- a carriage that moves relative to the recording medium;
- and
- a biasing member that biases the inkjet head mounted in the carriage for position alignment of the inkjet head relative to the carriage,
- the carriage comprising:
- a carriage-side contact portion that makes contact with the inkjet head in an orthogonal direction orthogonal to a direction in which the ink is discharged from the inkjet head mounted in the carriage,
- the inkjet head being biased by the biasing member in a pushing direction included in the orthogonal direction in which the inkjet head is pushed against the carriage-side contact portion,
- the carriage-side contact portion serving to regulate, by way of contact with the inkjet head, movements of the inkjet head in at least two directions that includes the pushing direction included in the orthogonal direction;
- the biasing member comprises:
- a pushing direction biasing portion that biases the inkjet head in the pushing direction;
- and
- a different direction biasing portion that biases the inkjet head in at least a direction included in the orthogonal direction other than the pushing direction, and an axis direction of the direction included in the orthogonal direction is different from an axis direction of the pushing direction.
An ink discharge unit, comprising:
- an inkjet head that discharges an ink toward a recording medium;
- a carriage that moves relative to the recording medium;
- and
- a biasing member that biases the inkjet head mounted in the carriage for position alignment of the inkjet head relative to the carriage,
- the carriage comprising:
- a carriage-side contact portion that makes contact with the inkjet head in an orthogonal direction orthogonal to a direction in which the ink is discharged from the inkjet head mounted in the carriage,
- the inkjet head being biased by the biasing member in a pushing direction included in the orthogonal direction in which the inkjet head is pushed against the carriage-side contact portion,
- the carriage-side contact portion serving to regulate, by way of contact with the inkjet head, movements of the inkjet head in at least two directions that includes the pushing direction included in the orthogonal direction, wherein
- the carriage comprises:
- a body;
- and
- a fixing member fixable to the body,
- the biasing member, while being fitted to the fixing member, biases the inkjet head for position alignment of the inkjet head relative to the fixing member, and
- the carriage-side contact portion is disposed in the fixing member.
A unit assembling method for assembling an ink discharge unit, and the ink discharge unit comprising:
- an inkjet head that discharges an ink toward a recording medium;
- a carriage that moves relative to the recording medium, and the carriage comprises:
- a body;
- and a fixing member fixable to the body;
- and
- a biasing member that, while being fitted to the fixing member, biases the inkjet head for position alignment of the inkjet head relative to the fixing member,
- wherein the unit assembling method comprising:
- fitting the inkjet head to the fixing member while the inkjet head is being biased by the biasing member fitted to the fixing member;
- and
- performing subsequently position alignment of the inkjet head relative to the body,
- thereafter, the fixing member being fixed to the body while the inkjet head is being positionally aligned relative to the body.
