When both the robot arm 3B and the lens processing device 1C are in the operation-stoppedstate,the CPU 51 transmitsa third movement instruction, and the third installation position 11C and the angle which are set in S34, to the robot arm 3B (S35).The third movementinstruction isan instruction to move the eyeglass lens from the second installation position 10B ofthe cup attachmentdevice 1B tothe third installation position 10C of the lens processing device 1C through the above-described third route. 5 10 [0086] When receiving the fourth movement instruc- tion, based on the third work position P3, the fourth work position P4, the third installation position 10C, the com- pletion position 9, and the passage position on thefourth route, the control unit39 of the robot arm 3B controls the operation of the arm unit 30 and the arm movement unit 41 so that the eyeglass lens is moved from the third in- stallation position 10C tothe completion position 9 (S42). The controlunit39 ofthe robotarm3B notifies the control device 5 that the eyeglass lens is completely moved to the completion position 9 (S43). [0083] When receiving thethird movementinstruction, based on thethird work position P3 stored in the position storing process (refer to FIGs. 3A and 3B), the second installation position 10B, the additional position on the third route,and the third installation position 11C and the angle which are transmitted in S35, the control unit 39 of the robot arm 3B moves the eyeglass lens from the sec- ond installation position 11B to the third installation po- sition 10C (S36). Specifically, in a state where the arm unit 30 itself is moved to the third work position P3, the control unit 39 of the robot arm 3B causes the holding unit 37 to hold the eyeglass lens installed at the second installation position 10B. Next, the control unit 39 moves the eyeglass lens at a designated angle to the third in- stallation position 10C transmitted in S35 while causing the eyeglass lens to pass through the passage position on the third route. The control unit 39 releases the eye- glass lens held by the holding unit 37 to install the eye- glass lens at the third installation position 10C. The con- trol unit 39 may consider the information of the cup po- sition and the information of the attachment angle, when the eyeglasslens iscaused topass through the passage position on the third route. 35 30 [0088] As illustrated in FIG. 2, the robot arm 3 accord- ing to the present embodiment can pivot the holding unit 37 around the rotationaxis(forexample,the rotationaxis X1) extending in the direction which intersects with the installationsurface (base 40)to orienttheholding unit37 toward each of the eyeglass manufacturing devices 1. Therefore, in contrast to a case where the eyeglass lens is moved between the plurality ofdevices by the convey- or, the disposition of the plurality of devices is much less likely to be limited. 25 20 15 [0087] As described above, in the eyeglass lens pe- ripheral edge processing system 100 according to the present embodiment, the eyeglass lens is moved by the robot arm 3 between the plurality of eyeglass manufac- turing devices 1 in different housings for performing dif- ferent steps. Furthermore, the arm unit 30 of the robot arm 3 has the plurality of joint portions J1 to J6. Accord- ingly, compared to a case where the eyeglass lens is moved between the plurality ofdevicesbya robothaving a single rotation axis ora conveyor, a positional relation- ship betweenthe plurality ofeyeglass manufacturing de- vices 1 is less likely to be limited. [0084] The control unit 39 of the robot arm 3B notifies the control device 5 that the eyeglass lens is completely moved to the third installation position 10C (S37). The CPU 51 of the control device 5 transmits an instruction tostartprocessing the eyeglass lens,tothe lens process- ing device 1C (S38).Thecontrolunitofthe lensprocess- ing device 1C processes the peripheral edge of the eye- glasslensin accordance with the targetlens shape meas- ured by an eyeglass frame shape measurement device (not illustrated) (S39). When the process in S39 is com- pleted, the control unit of the lens processing device 1C transmitsthe completionnotification ofthe process to the control device 5 (S40). 40 45 [0089] Referring to FIG. 6, one of modification exam- ples of the above-described embodiment will be scribed. FIG. 6 is a plan view ofan eyeglass lens periph- eral edge processing system 200 according to the mod- ification example. The modification example illustrated in FIG. 6 adopts the same devices as the lens meter 1A, the cupattachmentdevice 1B,the lens processingdevice 1C, and the robot arm 3 which are used in the above- described embodiment.However,whereas the two robot arms 3A and 3B are used in the above-described em- bodiment, one robot arm 3 is used in the modification example illustrated in FIG. 6. In this way, the number of the robot arms 3 used in the eyeglass lens peripheral edge processing system may be one,or may be three or more. In addition, although the robot arms 3A and 3B according to the above-described embodiment move on the installation surface, the robot arm 3 is fixed in the modification example illustrated in FIG. 6. In this way, a position ofthe armunit30ofthe robotarm3maybe fixed. [0085] When receiving the completion notificati transmitted in S40, the CPU 51 of the control device 5 determines whether or not the robot arm 3B is in t operation-stopped state.Whenthe robotarm 3B is in the operation state, the robot arm 3B is brought into standby state.When the robotarm3Bisin the operation- stopped state, the CPU 51 transmits a fourth movement instruction to the robot arm 3B (S41). The fourth move- ment instruction is an instruction to move the eyeglass lens from the third installation position 10C of the lens processing device 1C to the completion positio [0090] In the modification example illustrated in FIG. 6, the plurality of eyeglass manufacturing devices 1 are 50 55 (Modification Example) 15
