A liquid crystal display device using a plastic substrate becomes required to have high resolution, high opening ratio, high reliability, or the like, with the increasing of a screen size. The optical fiber amplifier can comprise a gain optical fiber that receives and optically amplifies picosecond optical pulses by operating in a nonlinear regime wherein the picosecond optical pulses can be spectrally broadened by a factor of at least 8 during amplification thereof. In addition, the scanner may support duplex scanning by adding a second image sensor, for example, in the document handler. The axis of the workpiece table forms an acute angle with the central axis of the support surface. Such an embodiment is useful over conventional methods because adjusting the pre-charge voltage can result in power savings. Each partition is substantially parallel to a scanning direction of the cartridge body.
