Abstract: A cleaning bath is provided on a base of a liquid ejection apparatus. A cleaning liquid supply section and a cleaning liquid discharge section are connected to the cleaning bath. The cleaning liquid supply section supplies cleaning liquid to the cleaning bath. The cleaning liquid discharge section drains the cleaning liquid from the cleaning bath. After having formed dots, a head unit is moved to the position immediately above the cleaning bath. Reflective mirrors are then immersed in the cleaning bath in the vicinity of an inlet pipe through which the cleaning liquid is introduced into the cleaning bath. An ejection head is also immersed in the cleaning bath in the vicinity of an outlet pipe through which the cleaning liquid is drained from the cleaning bath.

Abstract: According to an aspect of the invention, a liquid ejection apparatus including a head unit is provided. The head unit is movable on an object at least in two-dimensional directions. The head unit includes an ejecting portion and a radiating portion. The ejecting portion ejects droplets onto the object. The radiating portion radiates a laser beam onto the droplet received by the object. A controller adjusts the position of the ejecting portion and the position of the radiating portion in correspondence with a movement direction of the head unit. Thus, productivity is improved by efficiently drying and baking ejected liquid droplets.

Abstract: A magnetic head assembly within a transducer is caused to float over the recording surface of a medium during operation while being in contact with the surface in the non-operational state. The transducer is supported by a load beam via a flexible member which deforms under the influence of frictional force between the transducer and the surface during landings and take-off. The load beam has integral stop plates which abut against a part of the transducer to regulate the deformation of the flexible member so that it stays within a predetermined range in the event of any relatively high frictional force being applied to the transducer.
