  • Patent number: 12283498
    Abstract: A light diffusion plate is placed on an upper surface of an upper chamber window. A blasting process is applied to a lower surface of the light diffusion plate to provide the lower surface in the form of frosted glass. When the light diffusion plate is placed on the upper surface of the upper chamber window, the light diffusion plate and the upper chamber window do not closely adhere to each other. The frosted glass releases a mass of air entering between contact surfaces of the light diffusion plate and the upper chamber window to the outside even if the mass of air thermally expands during heat treatment. This restrains the occurrence of a phenomenon in which a thin layer of air is trapped between the light diffusion plate and the upper chamber window to prevent the sliding of the light diffusion plate resulting from the air layer.

  • Patent number: 12263672
    Abstract: Disclosed is a printing apparatus in which web paper is transported to a printing face contact roller in a swirling form while a direction thereof is turned by first to fourth turning rollers. Heating units are arranged so as to face a printing face of the web paper between the two first and second turning rollers, between the two third and fourth turning rollers, and between the fourth turning roller and the printing face contact roller individually. Such arrangement can achieve a compact drying mechanism. The heating units each directly heat inks on the printing face, and thus do not overheat the web paper. Moreover, the heating units are not directed upward. This avoids contact of the web paper to a front side face of each of the heating units when the web paper slackens.
