Abstract

PROBLEM TO BE SOLVED: To quickly and accurately do spectacle lens shaping work while meeting customer needs. SOLUTION: An order placing terminal 1 in an optician's shop is connected to an order receiving terminal 6 on the lens worker side via a value added network 4. The order placing terminal 1 takes lens shape data for a spectacle frame measured by a frame reader 2 and immediately discriminates whether the production of a lens shape based on the taken lens shape data is possible or impossible using a raw lens specified by key input. If it is possible, lens shape working data including the lens shape of the spectacle frame, the geometrical center of the lens shape and the optical center thereof is fed from the order placing terminal 1 to the order receiving terminal 6. The lens shape working data is transferred via the order placing terminal 6 and a working machine control terminal 7 to a working machine 8 by which a lens is cut into the lens shape in accordance with the lens shape working data.

FIG. 5 shows an example of the lens shape data 31 of the eyeglass frame measured by the frame reader 2,
A large number (200 in this embodiment) of radiations 33 are arranged at predetermined angular intervals around the boxing center 32.

The ordering terminal 1 immediately determines whether or not the captured lens shape can be manufactured using the unprocessed lens specified by key input. When the ordering terminal 1 determines that the captured lens shape can be manufactured, the ordering terminal 1 transmits the input item data and the captured lens shape data via the modem 3 as lens processing data. I have.

In the present embodiment, the ordering terminal 1 corresponds to production possibility determination means, and the frame reader 2 corresponds to a lens shape measuring means. And the ordering terminal 1
And the frame reader 2 constitute a production availability determination device. The ordering terminal 1 also functions as a data input unit, a frame drawing unit, a geometric center calculation unit, an optical center calculation unit, and a determination unit.

The order receiving terminal 6 of the lens processor is a VA.
The lens machining data transmitted via N4 is transmitted to the modem 5
Receive through. The order receiving terminal 6 designs the lens and prepares a lens order book based on the received edging data, and prints the frame shape based on the received edging data.

FIG. 12 shows an example of a frame shape printed by the order receiving terminal 6. Left and right lens shape 50a,
Eye points 51a and 51b are respectively drawn in 50b, and a pair of mark points 52 are drawn so as to sandwich each eye point 51a and 51b. The mark 52 indicates the suction position of the suction cup at the time of lens edging.

The lens processing machine 8 cuts the set unprocessed lens into a predetermined lens shape based on the measurement data of the eyeglass frame to produce a lens shape, and forms the lens shape based on the result of the arrow calculation. Form an arrow.

Next, a lens ordering process using the ordering terminal 1 configured as described above will be described with reference to the flowcharts of FIGS. When the power is turned on to the ordering terminal 1, the screen is initialized and an input item screen is displayed (step 11). Next, input of each item is waited for by key input by the operator (step 12).

When the input of the input items is completed, the ordering terminal 1 causes the frame reader 2 to measure the eyeglass frame shape by the frame reader 2 and fetches the eyeglass frame shape data 31 as shown in FIG. 5, for example. (Step 1
3). Next, the ordering terminal 1 determines whether or not the captured lens shape can be manufactured using the unprocessed lens specified by key input (step 14). If it is determined that the ordering terminal 1 can be manufactured, the input item data input in step 12 and the lens shape data captured in step 13 are stored as lens processing data (step 16). . When it is determined that the ordering terminal 1 cannot be manufactured, the ordering terminal 1 waits for a change in the lens type, the spectacle frame, and the like, and executes the processing in step 12 and subsequent steps.

The determination as to whether or not to be manufactured in step 14 is performed as shown in FIGS. First, a frame shape 40 is drawn from the measured frame data, for example, as shown in FIG. 6, and the center of a rectangle 41 in which the frame shape 40 fits is determined as the boxing center 42 (step 2).
0). Subsequently, the pupil distance P in the input item data
Based on D, the geometric center distance FPD, the displacement distance UP, and the position of the boxing center 42, for example, an eye point (optical center) 43 is obtained as shown in FIG. 7 (step 21).

Next, a circle of a standard size having the radius of the lens specified by the input item is drawn around the eye point,
It is determined whether or not the frame shape falls within the standard circle (step 22). Therefore, for example, as shown in FIG.
Is drawn, it is determined that the frame shape 40 falls within the standard circle 44.

If it is determined that the frame shape falls within the standard circle, the product name, S frequency and C
It is determined whether a stock lens or a custom lens is manufactured based on the presence or absence of a stock lens corresponding to the product from the frequency (step 26). If it is determined that there is no stock lens corresponding to the stock lens, it is manufactured with a custom lens. Is determined (step 27). If it is determined in step 26 that there is an in-stock lens, then it is determined whether the lens is a color lens based on the input item data (step 28).
If it is a color lens, it is determined to be a stock (product) (step 29), and if it is not a color lens, it is determined to be a stock (step 30).

If it is determined in step 22 that the frame shape does not fit within the standard circle, a circle of a standard size having the radius of the lens specified by the input item is drawn around the boxing center, and the frame is drawn. It is determined whether or not the shape falls within the standard circle (step 23). For example, as shown in FIG. 9, a standard circle 45 having a radius r2 is drawn around the eye point 43, and it is determined that the frame shape 40 does not fall within the standard circle 45. In this case, as shown in FIG. 10, a standard circle 46 having a radius r2 is drawn around the boxing center 42, and the frame shape 40 falls within the standard circle 46.

If it is determined that the frame shape falls within a standard circle centered on the boxing center, it is determined that the polishing is eccentric with a special order (step 25). If it is determined that the frame shape does not fit within the standard circle centered on the boxing center, it is determined that the frame shape cannot be manufactured (step 24).

As described above, in the present embodiment, the ordering terminal 1 installed in the eyeglass store receives the target lens shape of the eyeglass frame, the geometric center and the optical center of the target lens shape, the lens type used, and the like. The processing data is sent to the order receiving terminal 6 of the lens processing company via the VAN 4, and the lens processing company cuts the lens into a lens shape. Therefore, the eyeglass shop can complete the manufacture of the eyeglasses simply by obtaining the lens cut into a lens shape by a lens processor and fitting the lens into the eyeglass frame. For this reason, in the spectacle store, the skill training of the operator for cutting the spectacle lens can be omitted, and the work in the spectacle store can be standardized.

Further, in this embodiment, it is determined whether or not the lens shape in the lens processing data can be manufactured by the ordering terminal 1 installed in the eyeglass store, so that the lens shape cannot be manufactured. In this case, it is possible to immediately recognize that it is necessary to change the spectacle frame and the lens type, and to change the spectacle frame and the lens type.

In this embodiment, the ordering terminal 1 determines whether or not a target lens shape can be manufactured. However, whether or not the manufacturing is possible is determined by the information processing device in the VAN 4 or the order receiving terminal. 6. The result of the determination is sent to the ordering terminal 1
May be transmitted.

In this embodiment, the edging data communication system has only one lens processing company on the order receiving side. However, the present invention is applied to an edging data communication system having a plurality of lens processing companies on the order receiving side. You may.

Further, in this embodiment, the master data of the stock lens of the lens processing company stored in the ordering terminal 1 is updated from the order receiving terminal 6 via the VAN 4. The master data of the machine 1 may be updated by another method. For example, a lens processor sends a floppy disk recording the latest master data of stock lenses to an eyeglass store, and the eyeglass store updates the master data by reading data from the floppy disk into the ordering terminal 1. Is also good.
