Patent ID: 7088439

Claim:
A lens meter, comprising: a measurement optical system including a light-emitting optical system, which emits a measurement luminous flux to an eyeglass lens, and a light-receiving optical system having a light-receiving element, which receives the measurement luminous flux passing through the eyeglass lens; an eyeglass holding device configured to hold eyeglasses, provided between the light-emitting optical system and the light-receiving optical system; and an arithmetic control circuit which computes optical characteristics of the eyeglass lens based on an output of the light receiving element, wherein the eyeglass holding device includes a lens receiver, which supports the eyeglass lens, and an eyeglass sandwiching unit, which sandwiches the eyeglasses, the lens receiver is moved in a freely movable manner between a measurement optical path of the measurement optical system and a withdrawal position outside the measurement optical path, and the lens receiver is moved in the withdrawal position after the eyeglasses have been sandwiched by the eyeglass sandwiching unit.
