1. An inkjet printer including:
a plurality of inkjet heads that eject ink;
a carriage on which the plurality of inkjet heads are mounted;
a carriage drive mechanism that moves the carriage in a main scanning direction;
a first inclination adjustment mechanism for adjusting inclination of each of the inkjet heads with respect to the carriage in a pivoting direction having a sub scanning direction orthogonal to an up-down direction and the main scanning direction as an axial direction of pivoting; and
a second inclination adjustment mechanism for adjusting inclination of each of the inkjet heads with respect to the carriage in a pivoting direction having the main scanning direction as an axial direction of pivoting,
wherein
the first inclination adjustment mechanism includes a head fixing member to which the inkjet head is fixed;
the second inclination adjustment mechanism includes a holding member that holds the head fixing member;
the holding member is pivotable with respect to the carriage with a main scanning direction as an axial direction of pivoting; and
the head fixing member is pivotable with respect to the holding member with a sub scanning direction as an axial direction of pivoting,
wherein
the first inclination adjustment mechanism includes a first lever member pivotably held by the holding member, a first spring member that biases the first lever member toward one side in a pivoting direction of the first lever member, and a first micrometer head or a first adjustment screw for pivoting the first lever member toward the other side in the pivoting direction of the first lever member;
the second inclination adjustment mechanism includes a second lever member pivotably held by the carriage, a second spring member that biases the second lever member toward one side in a pivoting direction of the second lever member, and a second micrometer head or a second adjustment screw for pivoting the second lever member toward the other side in the pivoting direction of the second lever member;
the first lever member is engaged with the head fixing member, and when the first lever member is pivoted, the head fixing member is pivoted with a sub scanning direction as an axial direction of pivoting with respect to the holding member; and
the second lever member is engaged with the holding member, and when the second lever member is pivoted, the holding member is pivoted with a main scanning direction as an axial direction of pivoting with respect to the carriage.
