The position storing process is performed when a position storing mode for storing the storing target positions is set. The storing tar- getpositions include the installation positions 10A to 10C of the eyeglass lens in each of the plurality of eyeglass processing devices 1. In addition, in the present embod- iment,the standby position 8 andthecompletionposition 9 are also included in the storing target positions. In ad- dition, in the present embodiment, the passage position on the movement route of the eyeglass lens moved by the robot arm 3 is also included in the storing target po- sitions. tion of the lens meter" may be displayed on the display unit 7. The CPU 51 stores the n-th number (n ≥ 1) of the passage positions of the eyeglass lens on a first route fromthe standbyposition 8 to thefirstinstallationposition 10A (S4) in the memory device 52. In the present em- bodiment, the worker inputs the position storing instruc- tion the n-th number of times while manually moving the position of the arm unit 30 itself of the robot arm 3A and the position of the holding unit 37 of the arm unit 30 so thatthe holding unit37 thatholdsthe eyeglasslens pass- esthroughthe properfirstroute.In S4,the CPU51 stores the position of the arm unit 30 itself and the position of the holding unit 37 in the memory device 52, each time the storing instruction is input. As a result, the number of passage positions on the first route is stored. Next, the CPU 51 performs a storing process of the first installation position 10A (S5). In a state where the robot arm 3A is located at the second work position P2, the worker manually moves the holding unit 37 to the first installation position 10A, and inputs the storing instruc- tion.In S5,the CPU 51stores the position ofthe arm unit 30 itself when the storing instruction is input, as the sec- ond work position P2. In addition, the CPU 51 stores the position of the holding unit 37 (including the angle of the holding unit 37) when the storing instruction is input, as the first installation position 10A based on the second work position P2. [0063] In the eyeglass lensperipheraledge processing system 100 according to the presentembodiment, when a start instruction of the position storing process (that is, an instruction to perform the position storing process) is input, the CPU 51 of the control device 5 performs the position storing process illustrated in FIGs. 3A and 3B in accordance with the eyeglass lens peripheral  processing program stored in the memory device 52. However, as described above, the position storing proc- ess may be performed by a control unit other than the CPU 51 of the control device 5, or may be performed in cooperation with a plurality of the control units. 5 10 15 20 25 30 [0064] First, the CPU 51 causes the display unit 7 to display a screen forinstructing a workertosetthe standby position 8 (S1). In S1, for example, a message such as "please move the holdingunitto thestandbyposition and store the position" may be displayed on the display unit 7. Next, the CPU 51 performs a storing process of the standby position 8 (S2). In the present embodiment, the worker manually rotates the joint portions J1 to J6 of the arm unit 30 in a state where the robot arm 3A is located at the first work position P1, and moves the holding unit 37 to the standby position 8 (specifically, the position of the eyeglass lens on the tray installed at the standby position 8). Next, the worker operates the operation unit (forexample,the operation unit6 connected to the control device 5, or the operation unit of the robot arm 3A) to input a storing instruction of the standby position. In S2, the CPU 51 stores the position of the arm unit 30 itself of the robot arm 3A in the memory device 52 when the storing instruction is input, as the first work position P1. Furthermore, the CPU 51 stores the position of the hold- ing unit 37 (including an angle of the holding unit 37) in the memory device 52 when the storing instruction is in- put, as the standby position 8 based on the first work position P1. 50 45 40 35 [0066] Next, the CPU 51 causes the display unit 7 to display a screen forinstructing theworkerto performset- tings from the first installation position 10A of the lens meter 1A to the second installation position 10B of the cup attachment device 1B (S6). The CPU 51 stores the n-th number (n ≥ 1) of passage positions of the eyeglass lens on a second route from the first installation position 10A to the second installation position 10B (S7) in the memory device 52. The process of S7 according to the present embodiment is performed in a state where the position of the arm unit 30 itself is fixed to the second work position P2. Next, the CPU 51 performs the storing process of the second installation position 10B (S8). A main flow of the processes in S6 to S8 is the same as that of the above-described processes in S3 to S5, and thus, detailed description will be omitted. [0067] Next, the CPU 51 causes the display unit 7 to display a screen forinstructing theworkerto performset- tings from the secondinstallationposition 10B ofthe cup attachmentdevice 1B to the third installation position 10C ofthe lensprocessing device 1C (S9).The CPU 51 stores the n-th number (n ≥ 1) of passage positions of the eye- glass lens on a third route from the second installation position 10B to the third installation position 10C (S10) in the memory device 52. In a state where the robot arm 3B is located at the third work position P3, the worker inputs the position storing instruction the n-th number of times while manually moving the holding unit 37 so that the holding unit37passesthrough the properthird route. In S10, the CPU 51 stores the position ofthe holding unit 37as the passage position,eachtimethe storing instruc- 55 [0065] Next, the CPU 51 causes the display unit 7 to display a screen forinstructing the workerto performset- tings from the standby position 8 to the first installation position 10A ofthe lensmeter1A (S3).In S3,forexample, a messagesuch as "please store the installation position of the lens meter after storing the n-th number passage positions of the lens up to the installation posi- 12
