    摘要： An optical sheet includes a sheet-like body portion, and unit prisms arranged on one surface of the body portion. Each unit prism extends linearly in a direction intersecting the arrangement direction. Each unit prism, when viewed in a direction parallel to the arrangement direction of the unit prisms, has an uneven polygonal-line-shaped contour and, with reference to raised portions defined by the polygonal-line-shaped contour of each unit prism, the distance between a top of each raised portion, a farthest point from the body portion in the raised portion, and the body portion in the normal direction of the body portion is not constant. The optical sheet can prevent significant problems when it is superimposed on another member.

    摘要： The pattern printed sheet 1 of the present invention includes a substrate 2 and a non-visible light-reflective transparent pattern 3 printed on a surface of the substrate, wherein an ink for forming the transparent pattern 3 contains a non-visible light-reflective material capable of selectively reflecting a light having a wavelength in a non-visible light range, and the transparent pattern 3 printed on the surface of the substrate 2 has a multilayer structure in section which is repeated at predetermined intervals as observed by a scanning electron microscope, and reflects only a circular polarization component in a predetermined rotation direction relative to an incident light applied thereto. The pattern printed sheet is usable as a coordinate detecting means which is applicable a data input system of a type capable of directly hand-writing input data on an image screen of a display device, and has a reduced weight and a low price, and is readily obtained in the form of a large area sheet and can be mass-produced.

    摘要： Provided is an image projection system including a screen, an input terminal, an image processing unit, an image projector, and invisible light ray-shielding member, characterized in that: the screen has a pattern-printed sheet having reflection patterns for transmitting positional information by reflecting invisible light rays or absorption patterns for transmitting positional information by absorbing invisible light rays; the input terminal has an invisible light ray-applying portion, detects a reflected light ray of an invisible light ray, which is applied from the invisible light ray-applying portion and reflected from a specific site of the pattern-printed sheet, reads positional information of any one of the reflection patterns or any one of the absorption patterns, and outputs the positional information to the image processing unit; the image processing unit converts the positional information input from the input terminal into image information A, and transfers the image information A to the image projector; the image projector converts the image information A transferred from the image processing unit into visible light rays, and projects the visible light rays on the screen; and the invisible light ray-shielding means is placed in front of or inside the image projector, and removes the invisible light ray from the visible light rays to be projected. The present invention can provide the image projection system in which, even when a screen is large, the positional information of the screen can be simply input in a non-contact fashion with high accuracy, and image information converted from the input positional information can be further converted into visible light rays to be projected.
