Abstract:
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.
