The glasses framework measurement equipment and possesses this spectacle lens grinding device

摘要

PROBLEM TO BE SOLVED: To protect a feeler when a spectacle frame is fitted on a holding block by providing an orthogonal direction moving control means placing the feeler on the base side of a device at the time of the standby of a measurement and moving the feeler up to the location of the groove part of a spectacle frame when the measurement is started. ;SOLUTION: A roller moves from the guide part of a fixed guide plate to the guide part of a movable guide plate, a probe axis is pushed up by an arm 2157 and a lens edge probe 2125 is kept to the height of a measuring surface. Further, when a probe driving part moves, the lens edge probe 2125 is inserted into a lens groove of a lens frame, a probe part stops moving at an FR and the probe driving part moves up to an FRL and stops there. As a result, the arm 2157 is separated from a roller 2131 and the lens edge probe 2125 lowers from a measuring plane. The probe part moves on a guide shaft according to the radius vector of the lens frame.;COPYRIGHT: (C)1998,JPO
