摘要： The present invention provides a lens meter capable of accurately measuring the optical characteristics of a lens including additive diopter and of providing highly reliable data representing the optical characteristics of the lens. The lens meter projects measuring light through a target mark on a lens, focuses an image of the target mark in a target image on a photo-detecting device, and determines the optical characteristics of the lens on the basis of a locus of the target image detected by the photo-detecting device. The lens meter comprises an additive diopter measuring mode selector switch, a control means for shifting the lens to position measuring points distributed at predetermined intervals on the lens successively on a measuring optical axis and measuring the refractive power of the lens at each measuring point, a position detecting means for detecting the distance of each measuring point from a predetermined reference point, and a display means for displaying the relation between the distance of the measuring point from the reference point and the variation of the spherical refractive power of the lens.

摘要： A lens meter includes a measurement optical system having a light source, measurement target plate, and light receiving sensor. A lens table has an opening where a measurement optical axis of the measurement optical system passes. A frame support member includes a support plate that contacts a left rim and right rim of a spectacle frame. The support plate is moved toward the lens table by a guide mechanism. The frame support member further includes a cutout portion in the support plate that allow the lens, placed on the lens table, to measure a point near an edge of the lens located on the support plate side. A pad contacts and prevents the rim from entering the cutout portion. The pad is provided in at least a part of the cutout portion. A pad moving mechanism moves the pad from the contact surface.
