A carriage device includes a head unit, a printing head and a carriage. The head unit has a sub-plate attached to a head plate via an adjustment mechanism. The printing head is attached to the head plate via the sub-plate. The carriage retains the head unit. The adjustment mechanism includes a first-direction adjustment plate, a rotation position adjustment plate, and a pitch angle adjustment plate. The first-direction adjustment plate adjusts a position of the sub-plate with respect to the head plate in a first direction. The rotation position adjustment plate adjusts, in a predetermined plane, a rotation position of the sub-plate with respect to the head plate about a rotational axis that is normal to the predetermined plane. The pitch angle adjustment plate adjusts a pitch angle of the sub-plate with respect to the head plate, the pitch angle being in relation to the predetermined plane. |
