Therefore, the eyeglass lens is more smoothly processed. [0025] However, it is possible to omit the control for moving the eyeglass lens from the last eyeglass manu- facturing device to the completion position. Even in this case, the worker can easily handle the eyeglass lens, only by unloading the eyeglass lens from the installation position ofthe lasteyeglassmanufacturing device.Inad- dition, the standby position and the completion position may be the same position, or may be different positions. 5 10 [0029] A specific method for moving the eyeglass lens can be appropriately selected, based on the information ofthe cup position.Forexample,thememorydevice may store the installation position of the eyeglass lens in the lens processing device in a case where the cup is at- tached to a reference position of the lens surface (for example, a center of the lens surface). In this case, the controllermay acquire a direction and a distance in which the cup position is displaced from the reference position on the lens surface, based on the information of the cup position, and may adjust the installation position of the lens processing device for moving the eyeglass lens so that the displaced direction and distance are offset. 15 [0026] When the positionstoring process isperformed, in addition to the installation position, the controller may further store passage position information indicating a passage position on a movement route of the eyeglass lens moved by the robot arm in the memory device, as the storing target position. When the movement process is performed, the controller may control the operation of the robot arm based on the installation position informa- tion and the passage position information which stored in the memory device, to move the eyeglass lens topass through the passage position.Inthiscase,a prop- er passage position is stored in the memory device so that the eyeglass lens moves to pass through a proper route. Therefore, for example, a possibility that the mov- ing eyeglass lens may fallaftercolliding with thehousing of the device is reduced. Each of a route for moving the eyeglass lens to the installation position and a route for moving the eyeglass lens from the installation position can be set to the proper route. Therefore, the eyeglass lens is more smoothly processed. 20 [0030] The controllermayacquire information ofan at- tachmentangleatwhich the cupattached to the eyeglass lens by the cup attachmentdevice isattachedto the eye- glass lens. When the eyeglass lens is moved to the in- stallation position ofthe lensprocessing device,thecon- troller may set an angle at the installation position of the eyeglass lens to which the cup is attached, based on the information ofthe attachmentangle.In thiscase,regard- less ofthe attachmentangle of the cup which ischanged dependingon tothe eyeglass lens,the chuck shaftofthe lens processing device is properly mounted on the cup. Therefore, the eyeglass lens is more smoothly proc- essed. 25 30 35 40 45 [0027] Theplurality ofeyeglass manufacturing devices may include a cup attachmentdevice and a lens process- ing device. The cup attachment device attaches a cup to a lens surface of the eyeglass lens. The lens processing device mounts the eyeglass lens with mounting a chuck shafton thecupattached to theeyeglass lensby thecup attachment device, and steps the peripheral edge of the mounted eyeglass lens. In this case, after the cup is at- tachedto the eyeglasslensbythecup attachmentdevice, the eyeglass lens is moved from the cup attachment de- vice to the lens processing device by the robot arm, and the peripheral edge of the eyeglass lens is processed. Therefore,atleasttwo steps forprocessing the eyeglass lens are smoothly performed by the eyeglass lens pe- ripheral edge processing system including the plurality of devices. [0031] A specific method for setting an angle of the eyeglass lens at the installation position of the processing device can be appropriately selected, based on the information of the attachment angle of the cup. Forexample,the information ofthe angle ofthe eyeglass lens at the installation position of the lens processing device in a case wherethe cup isattached to the eyeglass lens at a reference angle (for example, at an angle par- allelto an opticalaxis) maybe included in the installation position information indicating the installation position of the lensprocessing device which isstored in the memory device. In this case, the controller may acquire displace- ment between the reference angle and the attachment angle, based on the information of the attachment angle ofthe cup,and may adjustthe angleofthe eyeglass lens at the installation position of the lens processing device so that the displacement of the angle is offset. [0028] The controller may acquire information of a po- sition on the lens surface to which the cup is attached by the cup attachment device (hereinafter, referred to as a "cup position"). When g the eyeglass lens is moved to the installation positionofthe lens processing device,the controller may move the eyeglass lens to the installation position where the chuck shaft of the lens processing device and the cup position coincide with each other, based on the information of the cup position. That is, the controller may adjust the installation position of the lens processing device which moves the eyeglass lens,based on the cup position. In this case, regardless of the cup [0032] The plurality ofeyeglass manufacturing devices used in the eyeglass lens peripheral edge processing systemare notlimited totwo ofthecup attachmentdevice and the lens processing device. For example, in addition to the cup attachment device and the lens processing device, a lens meter for measuring an optical character- istic oftheeyeglass lens may beincluded inthe eyeglass lens peripheral edge processing system. In this case, first, the lens meter performs a lens measurement step which is one of the plurality of steps for processing the peripheral edge of the eyeglass lens. Next, the cup at- 50 55 7
