Abstract:
1. An eyeglass frame shape measurement apparatus, comprising: a frame holder configured to hold right and left rims of an eyeglass frame, the right and left rims including grooves respectively; a measuring unit including a tracing stylus configured to be inserted into the grooves of the right and left rims, and detect movement of the tracing stylus to measure shapes of the rims; a first measurement start signal input unit configured to input a first measurement start signal for a first measuring mode in which whole peripheries of the right and left rims are measured in a state that the right and left rims of the eyeglass frame are held by the frame holder; a second measurement start signal input unit configured to input a second measurement start signal for a second measuring mode in which the whole periphery of one of the right and left rims of the eyeglass frame is measured in a state that the one of the right and left rims of the eyeglass frame is held by the frame holder; a third measurement start signal input unit for inputting a third measurement start signal for a third measuring mode in which nose side portions of the left rim and the nose side portion of the right rim are partially measured in a state that the right and left rims of the eyeglass frame are held by the frame holder, the nose side portions including nose side ends of the left and right rims; and a controller configured to drive the measuring unit to measure the whole peripheries of the right and left rims when the first measurement start signal is input, for driving the measuring unit to measure the whole periphery of the one of the left and right rims held by the frame holder when the second measurement start signal is input, and for driving the measuring unit to measure partially the nose side portions of the left and right rims when the third measurement start signal is input.
