Abstract
A target lens shape measuring device for measuring a target lens shape of an eyeglass lens has a measuring section including: a template feeler contactable with a periphery of a template; a first supporting base to which the template feeler is attached; a first motor and a link mechanism that move the template feeler and the first supporting base between a measuring position and a retracted position, wherein the link mechanism located between the measuring position and the retracted position is engaged with the first supporting base, and the link mechanism located at the measuring position is disengaged with the first supporting base; a second motor that moves the template feeler and the first supporting base in a radius vector direction of the template; and a first encoder that detect an amount of movement of the template feeler and the first supporting base in the radius vector direction of the template. A calculating section obtains radius vector information of the template based on the amount of movement detected by the first encoder.
