Provided is an illumination panel that can emit light with a bright front surface part of the panel while preventing light from a light source from appearing as a bright spot on the front surface part of the panel even when further thickness reduction is achieved by reducing the thickness of the outer frame. The illumination panel comprises an outer frame (3), a rear surface plate (2) arranged in a state of covering the rear side of the inner region surrounded by the outer frame (3) and in a state where a large number of light sources (1A) are dispersedly arranged on the front surface side, a light diffusing sheet (4B) having a light diffusing property and stretched in a state of covering the front side of the inner region, and a front surface sheet (4A) having a light diffusing property, constituting the front surface part of the panel and stretched in a state of covering the front side of the light diffusing sheet (4B), wherein the front surface sheet (4A) is configured by providing a first glass cloth woven with a first glass yarn as a base material, and the light diffusing sheet (4B) is configured by providing a second glass cloth woven with a second glass yarn thicker than the first glass yarn as a base material.
The present invention makes it possible to make the amount of adhering coating material uniform over an entire application area on the outer peripheral surface of an application roller and uniformly apply the coating material to a sheet while reducing the effort and time required to fabricate a plate-like member and an application roller. Coating material J is supplied to the outer peripheral surface of an application roller 2 in a coating material supply location A1 on the upstream side in the direction of roller rotation. Excess coating material J is removed from the outer peripheral surface of the application roller 2 by bringing the tip side 5a of a plate-like member 5A into the proximity of or into contact with the outer peripheral surface of the application roller 2 at a coating material amount adjusting location A2 more to the downstream side in the direction of roller rotation than the coating material supply location A1. The coating material J is applied to a sheet S by the outer peripheral surface of the application roller 2 coming into contact with the outer surface of the sheet S at an application location A3 more to the downstream side in the direction of roller rotation than the coating material amount adjusting location A2. The plate-like member 5A is given a curved shape curved toward the downstream side in the direction of roller rotation, and the outer surface of the tip side 5a of the curved-shape plate-like member 5A is placed in proximity to or in contact with the outer peripheral surface of the application roller 2 at the coating material amount adjusting location A2.

The purpose of the present invention is to provide an image sheet capable of maintaining a favorable image quality without the occurrence of changes in density or color in areas of the image that have low density. An image sheet 3 for both transmitted light and reflected light comprises: a base layer 10 made of a translucent white resin film; a first image layer 11 made of a first color image 11G formed on one surface of the base layer; a second image layer 12 made of a white second image 12G formed on the first image layer so that positions of an image that is the same as the first image overlap; and a third image layer 13 made of a third color image 13G formed on the second image layer so that positions of an image that is the same as the first image overlap.

SHEET FOR IMAGE FOR TRANSMITTED LIGHT, AND IMAGE SHEET OBTAINED USING SAME FOR TRANSMITTED LIGHT
The purpose of the present invention is to efficiently obtain satisfactory light-diffusing properties and high flameproof properties. A base (2) constituted of glass cloth is coated with resinous layers (3B, 3C) to configure a sheet that has light-diffusing properties and light-transmitting properties. The resinous layers (3B, 3C) have been configured as flame-retardant light-diffusing layers by incorporating a particulate inorganic flameproofing agent having light-diffusing properties in place of a white pigment or light-diffusing agent into a base resin.

LIGHT-REFLECTION/LIGHT-TRANSMISSION IMAGE SHEET AND METHOD FOR FORMING LIGHT-REFLECTION/LIGHT-TRANSMISSION IMAGE SHEET
The purpose of the invention is to enable a natural and clear image to appear in both light reflection and light transmission usage modes of a light-reflection/light-transmission image sheet having front and back-side images (3, 4) overlying each other on opposite sides of a sheet-like base material (2) having reflective and transparent properties. In order to achieve this, the density distribution of the back-side image (4) of the light-reflection/light-transmission image sheet is adjusted such that a high-density part (N1) thereof which is higher than a setting density (α) in the density distribution of the front-side image (3) is reduced to the setting density (α).

METHOD FOR PRINTING ON BOTH SIDES OF PAPER, PAPER FEEDING APPARATUS, AND PRINTER PAPER
Double-sided printing of images with high positional accuracy even on large-sized paper is accomplished by using paper, upon both ends of which punch-holes for transportation have been disposed, and a feeding apparatus (YH) provided with a drive roller (13) that rotationally drives while in contact with the paper and two tractors (14), which have a plurality of pins that engage with the punch-holes, that are disposed on both ends of the drive roller and rotationally drive by means of the rotationally driving force of the same shaft as the drive roller. The paper is set into the feeding apparatus, and the paper is fed in that state at a speed matching the movement of the pins while an image is printed upon one surface of the paper. The paper having printing finished upon one surface is flipped and set into the feeding apparatus, and the paper is fed in that state at a speed matching the movement of the pins while an image is printed upon the other surface of the paper.
