Therefore, a space for installing the eyeglass lens peripheral edge processing system 200 is reduced. 1 eyeglass manufacturing device 1A lens meter 1B cup attachment device 1C lens processing device 3 robot arm 5 control device 10A first installation position 10B second installation position 10C third installation position 11C, 12C chuck shaft 30 arm unit 37 holding unit 39 control unit 40 base 41 arm movement unit 51 CPU 52 memory device 60 cup 100, 200 eyeglass lens peripheral edge processing system J1 to J6 joint portion X1 pivot axis LE eyeglass lens [0091] In addition,in themodification example illustrat- ed in FIG. 6, in a case where the plurality of eyeglass manufacturing devices 1 are viewed in the direction of the pivotaxis X1 ofthe robotarm 3 (thatis,in the present embodiment,fromabove),theplurality ofeyeglassman- ufacturing devices 1 are disposed clockwise or counter- clockwise (clockwise in the present embodiment) in the order of performing the steps on the eyeglass lens. That is, the lens meter 1A that first performs the lens meas- urement step, the cup attachment device 1B that sec- ondly performs the processing preparation step, and the lens processing device 1C that lastly performs step are disposed clockwise in this order. 5 10 15 20 Therefore, the robot arm 3 pivots the holding unit  around the pivot axis X1. Therefore, the robot arm 3 can smoothly move the eyeglass lens with respect to each of the plurality of eyeglass manufacturing devices 1 in the order of performing the steps. 25 [0092] Furthermore, in the modification example illus- trated in FIG. 6, together with the plurality of eyeglass manufacturing devices 1, the standby position 8 and the completion position 9 (same position in FIG. 6) of the eyeglass lens are also disposed to surround the robot arm 3 along the circumferential direction round on the pivotaxisX1.Specifically,in the orderofmovingthe eye- glass lens (that is, the order of the standby position 8, the lens meter 1A, the cup attachment device 1B, the lens processing device 1C, and the completion position 9), the respective positions are disposed clockwis 30 35 Therefore, a space for installing the eyeglass lens pe- ripheral edge processing system 200 can be further re- duced. a plurality of eyeglass manufacturing devices thatperformmutuallydifferentsteps outofa plu- rality of steps for processing the eyeglass lens, and thatinclude mutuallydifferenthousings;and a robot arm that includes an arm unit having a plurality of joint portions, and a holding unit pro- vided in the arm unit to hold and release an ob- ject, and that rotates the arm unit via the joint portion to move the object held by the holding unit, wherein the robot arm rotates the arm unit to move at least an eyeglass lens serving as the object between the plurality of eyeglass manu- facturing devices. 40 45 [0093] The techniques disclosed in the above- scribed embodimentand modification example are mere- ly examples. Therefore, itispossible to change the tech- niques described as an example in the above-described embodimentandmodification example.Forexample,the eyeglass lens peripheral edge processing system may adoptonlya partofa plurality ofthe techniques described as an example in the above-described embodiment and modification example. In addition, the robot arm 3 may be fixed to a wall surface extending in the vertical direc- tion, instead of the horizontal installation surface. In ad- dition, in the above-described embodiment and modifi- cation example, the robot arm 3 directly moves the eye- glass lens from the installation position 10 of one eye- glass manufacturing device 1 to the installation position 10 of another eyeglass manufacturing device 1. Howev- er, the robot arm 3 may temporarily move the eyeglass lens to the other position (for example, the tray at the standby position 8 or the completion position 9) while moving the eyeglass lens between the plurality of instal- lation positions 10. 55 50 Claims 16 3.
