A coin conditioner is provided for cleaning or otherwise conditioning coins in a coin discriminator apparatus prior to transfer to a coin sensor. The liquid crystal display panel comprises a color filter substrate having a light shielding layer on a peripheral area and a common electrode on a display area and the peripheral area, and an array substrate having a pixel electrode on the display area and a separate and independent electrode with a fixed voltage on the peripheral area. In this manner, the phase of the dither matrix at the time of the quantization during test pattern printing matches the phase of the dither matrix at the time of the quantization during input image printing. In accordance with the invention a homogeneously tough three-dimensional knit structure is achieved when loops in specific portions are widened andor narrowed, this wideningnarrowing of the loops being done at many locations arranged distributed homogeneously over the area to be formed three-dimensionally. The output circuit connects the secondary-side coil assembly; the winding voltage sampler detects preset reference voltage of the primary-side coil assembly for the controller to regulate output voltage.
