## Abstract

A lens edging system, including: a spectacle frame measurement device and an order-side terminal device disposed at a spectacle lens order side; and an order-receiving side controller disposed at a spectacle lens order-receiving side, wherein the order-side terminal device and the order-receiving side controller are connected to each other via a communication line, the system further including: an information memory part for storing and holding information regarding a shape of a probe in the spectacle frame measurement device as probe information; and an edging shape calculation part for performing data correction reflecting an abutting mode of the probe indicated by the probe information when lens edging shape data is created at the spectacle lens order-receiving side, wherein a suitable size correction can be performed even when a frame shape of any kind of a spectacle frame is measured by the spectacle frame measurement device by performing the data correction.

## Claims

### Claim 1

A lens edging system, comprising:
a spectacle frame measurement device configured to measure a three-dimensional frame shape of a spectacle frame by abutting a probe on an inner circumferential groove of the spectacle fame;
an order-side terminal device configured to perform ordering of a spectacle lens that can be framed into the spectacle frame whose three-dimensional frame shape data is obtained using three-dimensional frame shape data as a measurement result obtained by the spectacle frame measurement device;
an order-receiving side controller configured to receive an order from the order-side terminal device, and create lens edging shape data based on the three-dimensional frame shape data regarding an order content; and
an edger configured to perform edging to the spectacle lens based on the lens edging shape data created by the order-receiving side controller,
wherein the spectacle frame measurement device and the order-side terminal device are disposed at a spectacle lens order side, and the order-receiving side controller and the edger are disposed at a spectacle lens order-receiving side, and the order-side terminal device and the order-receiving side controller are connected to each other via a communication line,
the lens edging system further comprising:
an information memory part configured to store and hold information regarding a shape of the probe in the spectacle frame measurement device as probe information, the information memory part included in the order-side terminal device or provided at a location on the communication line; and
an edging shape calculation part included in the order-receiving side controller and configured to specify an abutting mode on the inner circumferential groove of the probe indicated by the probe information over the whole circumference of the spectacle frame, using the probe information stored and held in the information memory part and obtained via the communication line, and perform data correction reflecting the abutting mode of the probe indicated by the probe information when the lens edging shape data is created.

### Claim 2 (depends on 1)

The lens edging system according to claim 1, wherein the information memory part is included in the order-side terminal device, and the order-side terminal device includes a probe information reporting part that reads the probe information obtained from the information memory part and reports it via the communication line to the order-receiving side controller, when ordering of a spectacle lens is performed to the order-receiving side controller.

### Claim 3 (depends on 1)

The lens edging system according to claim 1, wherein the information memory part is provided at a certain place on the communication line, and the order-receiving side controller includes a probe information acquisition part for acquiring the probe information by accessing the information memory part via the communication line, in addition to the edging shape calculation part.

### Claim 4 (depends on 1)

The lens edging system according to claim 1, wherein the information memory part is included in the order-side terminal device, and the order-side terminal device includes a shape data correction part that performs data correction reflecting an abutting mode of the probe indicated by the probe information stored in the information memory part, to three-dimensional shape data as a measurement result obtained by the spectacle frame measurement device, and ordering is performed to the order-receiving side controller using three-dimensional frame shape data after data correction by the shape data correction part at a side of the order-side terminal device.

### Claim 5 (depends on 2)

The lens edging system according to claim 2, wherein the order-side terminal device includes a probe information registration processing part for storing and holding the probe information in the information memory part.

### Claim 6 (depends on 4)

The lens edging system according to claim 4, wherein the order-side terminal device includes a probe information registration processing part for storing and holding the probe information in the information memory part.
