Abstract: A building face material with printed indications is provided, where, even when any part of the building face material is cut in a cutting process in a manufacturing process, each first printed indication is marked at an allowable distance from an end side of the building face material that is rectangular in a plan view, and printed indications are preliminarily marked at predetermined intervals, in a given column. The building face material 10 with printed indications includes printed indication strings each including one string group that is repeated in cycles, the string group being formed, in a plan view, on a rectangular flat face of the building face material, and the strip group consisting of multiple printed indications that are arranged, at regular first intervals, in a predetermined order along at least one straight line driven to a first side 11 or a second side 12 of a rectangle.

Abstract: There is provided an inspection apparatus for inspecting a plate-shaped inspection target being conveyed. The inspection apparatus includes a light source configured to emit a linear light. beam extending along the thickness direction of the inspection target to irradiate a side surface at a lateral end of the inspection target in a width direction orthogonal to a conveying direction of the inspection target, an imager configured to capture the light beam emitted from the light source and irradiating the side surface at the lateral end of the inspection target, an imager driving device configured to move the imager, and an imager controller configured to control the position of the imager. The imager controller is configured to control the position of the imager according to the position of the lateral end of the inspection target.

Abstract: An inspection method for inspecting a board-shaped inspection object with a pattern includes an imaging step of capturing an original image of an inspection surface of the inspection object, a digitization step of generating an image with two or three gradation levels by digitizing the original image captured by the imaging step using a threshold, and a determination step of inspecting the inspection object using the image generated by the digitization step.
