Abstract:
1. A layout setting device that sets layout of a target lens shape used as a processing shape with respect to an eyeglass lens, the layout setting device comprising: a target lens shape inputting unit that inputs target lens shape data of a template or a demo lens; a layout inputting unit that inputs layout data including data of a pupillary distance of a user; a display; a warp angle input unit that displays, on the display, a measuring screen that includes an angle measuring index for measuring a warp angle of an eyeglass frame, the angle measuring index including an x-axis reference line indicating 0° reference, a y-axis reference line perpendicular to the x-axis reference line and at least one angle measuring line, and that measures the warp angle based on a positional relationship between the eyeglass frame placed on the measuring screen and the displayed angle measuring index; a switching unit that switches a screen of the display to the measuring screen; and an arithmetic unit which obtains a shift amount in a direction of the pupillary distance and sets the layout of the target lens shape with respect to the eyeglass lens based on the input target lens shape data, the input layout data and the input warp angle data.
