[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
As shown in FIG. 1, the target lens processing data communication system of this embodiment includes an ordering terminal 1 as a data transmission device installed in each spectacle store, and a value-added communication network that relays an information processing device ( VAN) 4 and an order receiving terminal 6 as a data receiving device installed on the lens processing company side. The ordering terminal 1 and the order receiving terminal 6 are connected to the VAN 4 via the modems 3 and 5, respectively.
[0010]
The ordering terminal 1 stores master data on the stock status of unprocessed lenses on the lens processor side, and this master data can be displayed on the screen. The master data can be constantly updated from the order receiving terminal 6 side via the VAN 4. The ordering terminal 1 displays an ordering screen having input items by a built-in program so that each input item can be input by key operation. As input items, order number, lens product name, color, S power (spherical power), C power (cylindrical power), astigmatism axis AX, interpupillary distance PD, geometric center distance FPD, and geometric center (boxing) There are items such as the distance UP of the optical center (eye point) from the center and the type of eyeglass frame.
[0011]
Connected to the ordering terminal 1 is a frame reader 2 for measuring the shape of the eyeglass frame. The ordering terminal 1 takes in the lens shape data of the spectacle frame measured by the frame reader 2. FIG. 5 shows an example of eyeglass shape data 31 of the spectacle frame measured by the frame reader 2, and a large number (200 in this embodiment) of radiation 33 is arranged at predetermined angular intervals around the boxing center 32. ing.
[0012]
The ordering terminal 1 immediately determines whether or not the target lens shape can be manufactured using an unprocessed lens specified by key input. If the ordering terminal 1 determines that the captured target lens shape can be produced, the input terminal data and the acquired target lens shape data are transmitted as target lens processing data via the modem 3. Yes.
[0013]
The order receiving terminal 6 on the lens processor side receives the target lens processing data transmitted via the VAN 4 via the modem 5. The order receiving terminal 6 performs lens design and lens arrangement book creation based on the received target lens processing data, and prints a frame shape based on the received target lens processing data.
[0014]
FIG. 12 shows an example of a frame shape printed by the order receiving terminal 6. Eye points 51a and 51b are drawn in the left and right target lens shapes 50a and 50b, respectively, and a pair of mark points 52 are drawn so as to sandwich the eye points 51a and 51b. A mark 52 indicates the suction position of the suction cup when processing the lens shape. The geometrical center distance FPD between the boxing centers 53, the distance RPD from the bridge center to the right eye point 51a, and the distance LPD from the bridge center to the left eye point 51b are located below the left and right target lens shapes 50a and 50b. The displacement distance UP of the eye points 51a and 51b from the boxing center 53 is depicted.
[0015]
Then, the order receiving terminal 6 transfers the received target lens processing data and lens design data to the processing machine control terminal 7. The order receiving terminal 6 can also transmit the order confirmation table to the spectacles store by facsimile via the VAN 4.
[0016]
The processing machine control terminal 7 performs an arrow string calculation based on the transferred lens shape processing data and lens design data. The processing machine control terminal 7 transfers the arrow calculation result and the spectacle frame measurement data to the lens processing machine 8 and manages the progress of lens processing.
[0017]
The lens processing machine 8 cuts the set unprocessed lens into a predetermined target lens shape based on the measurement data of the spectacle frame, and manufactures the target lens shape. Form.
[0018]
Next, lens ordering processing using the ordering terminal 1 configured as described above will be described with reference to the flowcharts of FIGS.
When the ordering terminal 1 is powered on, the screen is initialized and the input item screen is displayed (step 11). Next, input of each item is waited by key input by the operator (step 12).
[0019]
When the input of the input items is completed, the ordering terminal 1 causes the frame reader 2 to measure the lens shape of the spectacle frame, and takes in the lens shape data 31 of the spectacle frame as shown in FIG. 5, for example (step 13). ). Next, the ordering terminal 1 determines whether or not it can be manufactured using an unprocessed lens in which the captured target lens shape is designated by key input (step 14). If it is determined that the ordering terminal 1 can be manufactured, each input item data input in step 12 and the target lens shape data acquired in step 13 are stored as target lens processing data (step 16). . If it is determined that the ordering terminal 1 cannot be manufactured, the process waits for a change of the lens type, the spectacle frame, etc., and the processes in and after step 12 are executed.
[0020]
The determination of whether or not the production is possible in the step 14 is executed as shown in FIGS.
First, the frame shape 40 is drawn from the frame measurement data, for example, as shown in FIG. 6, and the center of the rectangle 41 in which the frame shape 40 fits is determined as the boxing center 42 (step 20). Subsequently, an eye point (optical center) 43 is obtained as shown in FIG. 7, for example, from the inter-pupil distance PD, the geometric center distance FPD and the displacement distance UP in the input item data, and the position of the boxing center 42 (step 21). ).
[0021]
Next, a standard size circle having the lens radius specified by the input item is drawn around the eye point, and it is determined whether or not the frame shape falls within this standard circle (step 22). Therefore, for example, when the standard circle 44 having the radius r1 is drawn around the eye point 43 as shown in FIG. 8, it is determined that the frame shape 40 is within the standard circle 44.
[0022]
When it is determined that the frame shape falls within the standard circle, it is determined whether the production of a stock lens or a custom lens is made based on the presence or absence of a stock lens corresponding to the product based on the product name, S frequency, and C frequency in the input item data. (Step 26) If it is determined that there is no stock lens, it is determined that the lens is manufactured with a custom lens (Step 27). If it is determined in step 26 that there is a lens in stock, it is then determined whether it is a color lens based on the input item data (step 28). If it is a color lens, it is in stock (product). If it is not a color lens, it is determined that it is in stock (step 30).
[0023]
If it is determined in step 22 that the frame shape does not fit within the standard circle, a standard size circle having the radius of the lens specified by the input item is drawn around the boxing center. It is determined whether it falls within the standard circle (step 23). For example, as shown in FIG. 9, a standard circle 45 having a radius r <b> 2 is drawn around the eye point 43, and it is determined that the frame shape 40 does not fit 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 fits in the standard circle 46.
[0024]
If it is determined that the frame shape falls within the standard circle centered on the boxing center, it is determined that the polishing is custom-made with eccentricity (step 25). If it is determined that the frame shape does not fit within the standard circle centering on the boxing center, it is determined that the frame shape cannot be manufactured (step 24).
[0025]
As described above, in this embodiment, target lens processing data such as the target lens shape of the spectacle frame, the geometric center and optical center of the target lens shape, and the type of lens used are obtained from the ordering terminal 1 installed in the spectacle store. The lens was sent to the order receiving terminal 6 via the VAN 4 and the lens was cut into a target lens shape. Therefore, the spectacles shop can complete the production of the spectacles by obtaining a lens cut into a target lens shape by a lens processing company and fitting this lens to the spectacle frame. For this reason, in the spectacle store, it is possible to eliminate the skill training of the operator for cutting the spectacle lens and to standardize the work in the spectacle store.
[0026]
Further, in this embodiment, since it is determined whether or not the target lens shape in the target lens processing data can be manufactured by the ordering terminal 1 installed in the spectacle store, the target lens shape cannot be manufactured. It is possible to immediately recognize that it is necessary to change the spectacle frame, the lens type, and the like, and it is possible to change the spectacle frame, the lens type, and the like.
[0027]
In this embodiment, it is determined whether or not the shape of the target lens can be manufactured by the ordering terminal 1, but the determination of whether or not the manufacturing is possible is performed by the information processing apparatus in the VAN 4 or the order receiving terminal 6. The determination result may be transmitted to the ordering terminal 1.
[0028]
In this embodiment, the target lens processing data communication system has only one lens processing company on the order receiving side. However, the target lens processing data communication system may include a plurality of lens processing contractors on the order receiving side. .
[0029]
In the present embodiment, the master data of the lens manufacturer's stock lens stored in the ordering terminal 1 is updated from the ordering terminal 6 side via the VAN 4. The master data may be updated by another method. For example, a floppy disk in which the latest master data of a stock lens is recorded from a lens processor is sent to a spectacle store, and the spectacle store updates the master data by reading data from the floppy disc into the ordering terminal 1. Also good.
[0030]
【The invention's effect】
As described above in detail, according to the present invention, it is possible to determine whether a spectacle store is in stock, whether it is a custom lens, and whether it is impossible to produce. If production is possible, it is possible to produce spectacles simply by ordering a lens that has been cut into a lens shape and placing the lens on the spectacle frame, and training the skills of workers for cutting spectacle lenses. On the other hand, the lens processor has an excellent effect that the frame shape based on the target lens processing data can be visually recognized before processing.
