A part of a toner supply path is formed in a setting unit, and a nozzle coupled to a toner container is provided, wherein the fitting direction of the toner container to the setting unit and the coupling direction of the nozzle to the toner container are different. Light is incident to each of the photocatalyst fibers constituting the filter assembly while an object fluid to be processed is introduced through an end face of the filter assembly to pass through the gaps among the photocatalyst fibers in the longitudinal direction. Each fin can be elongated in a second direction substantially orthogonal to the first direction to define a length. The disclosed embodiments of the invention show displaceable layers in the form of foldable cuffs on sleeves, epaulets, decorative pocket-like flaps, and faux seams. The plastic layer collimates light propagating therethrough. If the content associated with the file is binary content then the content associated with the file is stored in a second relational database table else the content associated with the file is stored in a third relational database table.
