Abstract: A laser processing unit according to the present invention includes a line-beam forming optical system configured to form a line-shaped laser beam from a laser beam with luminous flux, an imaging optical system configured to form the line-shaped laser beam on an object to be processed via a mask, a one-direction variable magnification optical unit including a concave cylindrical lens and a convex cylindrical lens, and a scanning mechanism. The concave cylindrical lens and the convex cylindrical lens are arranged along an optical axis and opposite to one another. A distance between the concave cylindrical lens and the convex cylindrical lens is changeable in order to change an imaging magnification of the imaging optical system in at least one direction.

Abstract: A determination device (1) includes a first storage unit (10), a determination unit (12), an input unit (13), and an update unit (14). The first storage unit (10) stores one or more processing rules of a post-printing processor (4) predetermined based on processing know-how for a post-printing process. The input unit (13) receives input of information about an update of the processing rules. The update unit (14) updates the processing rules stored in the first storage unit based on the input of information about the update of the processing rules. The determination unit (12) determines whether a post-printing processing instruction information generated by a pre-printing processor (2) satisfies the one or more processing rules.

Abstract: An ink jet head maintenance apparatus includes a suction member which includes a suction hole to suction ink and in which air in the suction hole is suctioned from one opening of the suction hole by a suction operation unit. The suction member includes a height adjustment surface which is adjacent to an opening surface in which the other opening of the suction hole is provided and in which an inner angle formed with the opening surface is an obtuse angle. Each position of the opening surface is able to move in a first direction including a normal direction of the opening surface in a predetermined initial state in response to external force applied to the height adjustment surface.
