Abstract: Provided is a block device that mounts a lens shape processing lens holder to a convex surface of a spectacle lens with two alignment reference marks for identifying a distance portion design reference point on a concave surface. The block device includes an imaging unit that images the alignment reference marks of the spectacle lens supported by a support unit from a convex surface side of the spectacle lens, an information processing unit that obtains expected imaged positions of the alignment reference marks imaged by the imaging unit, using information regarding the spectacle lens, when a posture of the spectacle lens supported by the support unit becomes a reference posture suitable for mounting the lens holder, and a display control unit that displays images of index marks indicating the expected imaged positions obtained in the information processing unit and images of the alignment reference marks.
