Spectacle frame shape measuring apparatus

A spectacle frame shape measuring apparatus holder which holds a frame template used to measure a frame shape of a rimless spectacle frame shape, comprising:

• a holder body having a template mount portion;
• a set screw which extends through a central hole formed in the center of the frame template to fix the frame template to the template mount portion;
• and
• a fixing pin which fixes said set screw to the template mount portion,
• wherein said set screw has a male thread portion,
• the template mount portion has a mount hole in which said set screw is inserted,
• said set screw has a pin guide groove which is formed in a surface of the male thread portion in an axial direction, and
• said fixing pin has a distal end portion protruding into the screw mount hole from a direction orthogonal to an axis of the screw mount hole, is located in the pin guide groove when inserted into the screw mount hole, and engages with a thread groove of the male thread portion of said set screw to fix said set screw when said set screw is fastened.

A spectacle frame shape measuring apparatus holder which holds a frame template used to measure a frame shape of a rimless spectacle frame shape, comprising

• a holder body having a lens mount portion,
• the lens mount portion including
• a cup shaft fixed in said holder body,
• a leap cup which is detachably fitted on the cup shaft and holds a lens,
• a lens press shaft which has a leap press for fixing the leap cup to said holder body by pressing the leap cup from a direction orthogonal to an axis of the leap cup and is movably disposed in said holder body,
• biasing means for biasing the lens press shaft in a direction in which the leap press presses the leap cup, and
• a set screw which is threadably engaged with said holder body and releases the leap cup from a pressed state produced by the leap press by moving the lens press shaft in a direction opposite to a biasing direction of the biasing means.

A spectacle frame shape measuring apparatus which measures a shape of a frame groove of a spectacle frame, and an outer circumferential shape of a frame template or a lens, comprising:

• a housing having a holder mount portion formed along one side edge of an opening portion which is open upward and in which the spectacle frame or the lens is inserted;
• a holder which holds the frame template or the lens;
• and
• an automatic discrimination mechanism which is mounted on the holder mount portion and automatically discriminates measurement modes for the frame template and the lens,
• wherein said holder includes
• a template mount portion having one surface on which a left or right frame template is mounted, and
• a lens mount portion having the other surface which is opposite to said one surface and on which a left or right lens is mounted,
• said holder is turned over and mounted on the holder mount portion such that the frame template faces down when the frame template is to be measured, and the lens faces down when the lens is to be measured,
• the holder mount portion includes a first fixing portion on which said holder is fixed when the left frame template or lens is to be measured, and a second fixing portion on which the right frame template or lens is to be measured, and
• said automatic discrimination mechanism includes
• a first sensor which is disposed on the first fixing portion and detects that said holder is mounted, and
• a second sensor which is disposed on the second fixing portion and detects that said holder is mounted.
