Abstract: Provided is an interlayer film for a laminated glass capable of obtaining laminated glass having excellent unity of appearance.

Abstract: An interlayer film for laminated glass is disclosed which contains a thermoplastic resin and has a portion where the amount of increase in the thickness is increased in a direction from one end to the other end in the region where the thickness is increased, or has a portion where the amount of increase in the thickness is decreased in a direction from one end to the other end in the region where the thickness is increased, and the ten-point average roughness Rz of the surface at a center position of the portion where the amount of increase in the thickness is increased, or the portion where the amount of increase in the thickness is decreased is 20 ?m or more.

Abstract: There is provided an interlayer film for laminated glass with which an air bubble can be made difficult to be left behind between a lamination glass member and the interlayer film when laminated glass is obtained. The interlayer film for laminated glass according to the present invention contains a thermoplastic resin and has one end and the other end being at the opposite side of the one and and having a thickness thicker than the one end, each of three values of the ten-point average roughness Rz of the surface at a position apart from the one end by 50 mm toward the other end, the ten-point average roughness Rz of the surface at a center position between the one end and the other end, and the ten-point average roughness Rz of the surface at a position apart from the other end by 50 mm toward the one end is 20 ?m or more, and a value calculated by subtracting the smallest value among the three values from the largest value among the three values is 3 ?m or more and 9 ?m or less.

Abstract: There is provided an interlayer film for laminated glass with which an air bubble can be made difficult to be left behind between a lamination glass member and the interlayer film when laminated glass is obtained.

Abstract: A rotary touch scanner for reading a bar code pattern includes: an outer frame formed with an opening portion, a rotary ring rotatably housed in the outer frame, a plurality of convex lenses mounted on an outer periphery of the rotary ring at regular angular intervals, rotary ring rotating device associated with the rotary ring, and a light receiving element disposed at a center of the rotary ring and having a light receiving surface directed to the opening portion of the outer frame; light scattered from a bar code label disposed in front of the opening portion of the outer frame being condensed and further focused onto the light receiving surface of the light receiving element as a real image through one of the convex lenses rotated by the rotary ring rotating device, continuously.
