Abstract: A printing apparatus including a platen unit including a platen surface on which a medium is disposed; a carriage including a print head and a sonic sensor, the carriage being configured to move; and a flat surface unit including a plurality of flat surfaces disposed such that distances between the sonic sensor and the plurality of flat surfaces are different from each other. The printing apparatus derives a relational expression from a surface-by-surface distance difference among the flat surfaces of the flat surface unit and a transmission/reception time to and from each surface, obtained based on a measurement by the sonic sensor, and determines, from the relational expression and the transmission/reception time measured at the medium, a distance to the medium.

Abstract: A liquid discharge apparatus that includes a first movable unit displaceably attached to a fixture portion, a rail unit that includes a planar portion formed along a first direction and is displaceable according to displacement of the first movable unit, and a carriage attached to the rail unit so as to be movable in the first direction and whose posture is changeable according to angle of the planar portion with respect to the fixture portion viewed in the first direction. The first movable unit includes a first adjuster that adjusts position of the rail unit with respect to the fixture portion in a second direction and a second adjuster that adjusts the angle of the planar portion with respect to the fixture portion as viewed in the first direction by pivoting the rail unit around a pivot axis that extends in the first direction.

Abstract: A liquid ejecting apparatus includes an ejecting unit that is capable of ejecting a liquid; and a tension adjusting unit that is rotatable about a rotational shaft and that is capable of applying a tension to a medium by coming into contact with the medium onto which the liquid is ejected. The tension adjusting unit is capable of applying the tension to the medium at a balancing position at which the tension adjusting unit is balanced by a weight of the tension adjusting unit.
