  With the above flow, the transporting process from the light emitting area A2 of the first light emitting panel 100a to the placement area A3 by the lighting device 1000 is completed. FIG. 12 shows a state in which the conveyance of the first light emitting panel 100a to the placement area A3 is completed. The first light emitting panel 100a is placed on the fixed plate 601 of the urging device 600. Further, the second light emitting panel 100b that stands by next to the first light emitting panel 100a is urged downward by the moving plate 602 and the urging coil spring 603 of the urging device 600, and is stably placed in the support device 10.

The apparatus 300A not only performs the transport control for transporting the second light emitting panel 100b located in the standby area A1 to the light emitting area A2, but also causes the first light emitting panel 100a in the light emitting area A2 to emit light, and then the second transport apparatus 300B. Accordingly, the first light emitting panel 100a located in the light emitting area A2 is transported to the placement area A3, and the second light emitting panel 100b located in the standby area A1 is transported to the light emitting area A2 by the first transport device 300A. It is also possible to perform conveyance control in which these are performed in parallel.

  Note that in the lighting device 1000, the sensors 201 to 204 can be any type of sensor such as an optical non-contact sensor and a mechanical contact sensor.

  The light-emitting panels 100a to 100d are provided with power receiving electrodes 103 and 104, and when the diameter of the transport roller is uniform over the entire length, the surface of the transport roller contacts the surface of the power receiving electrodes 103 and 104. In this case, the material used for the surface of the transport roller may adhere to the power receiving electrodes 103 and 104. When foreign matter adheres to the power receiving electrodes 103 and 104, it is conceivable that contact failure occurs between the power receiving electrodes 103 and 104 and the power receiving electrodes 402 and 403.

  14 has a first roller region 302a having a first diameter on both sides, and has a diameter smaller than the first diameter at a position through which the power receiving electrodes 103 and 104 pass. A second roller region 302b is provided. Thereby, the contact of the surface of the conveyance roller 302 to the power receiving electrodes 103 and 104 is avoided. As a result, it is possible to prevent foreign matter from adhering to the power receiving electrodes 103 and 104. The same applies to the transport rollers 305, 309, and 310 in contact with the power receiving electrodes 103 and 104.

In the conveyance from the light emitting area A2 of the light emitting panels 100a to 100d to the placement area A3 by the lighting device 1000 described in FIGS. 10 to 12, the placement area A3 provided on the fixed plate 601 of the urging device 600 is moved to the placement area A3. The light emitting panels 100a to 100d after emitting light were transported. In this case, in this illumination device 1000, the light emitting panels 100a to 100d placed on the fixed plate 601 are normally not used again thereafter.

  However, the specifications of the first light-emitting panel 100a and the second light-emitting panel 100b differ depending on the user's request (for example, color tone and brightness), and before the expiration date of the first light-emitting panel 100a is reached. When the first light emitting panel 100a is replaced with the second light emitting panel 100b, the first light emitting panel 100a is still in a usable state.

  Therefore, in order to enable reuse of the first light-emitting panel 100a in a usable state, in FIG. 15 and FIG. 16, the first light-emitting panel 100a is transported on the uppermost stage of the standby area A1. Like to do. Therefore, in this case, below the urging device 600, the top of the standby area A1 is the placement area A3. 15 and 16 are first and second conceptual views showing other states in which the light emitting panel is conveyed to the mounting area of the illumination device 1000.

  In the urging device 600, a plunger 613 capable of controlling the position of the moving plate 602 is used instead of the urging coil spring 603. Accordingly, as shown in FIG. 16, the plunger 613 is used to raise the moving plate 602 so that the first light emitting panel 100a is placed on the fourth light emitting panel 100d positioned at the uppermost stage. Mounting area A3 can be formed.

  After transporting the first light emitting panel 100a, it is possible to stably hold the light emitting panels 100b to 100d and the light emitting panel 100a located in the standby area A1 by using the plunger 613 to lower the moving plate 602. Become.

However, when considering the future use cycle of the light emitting panel, the first light emitting panel is not placed on the uppermost light emitting panel, for example, between the third light emitting panel 100c and the fourth light emitting panel 100d. The case where it is preferable to convey the light emission panel 100a can be considered. That is, there may be a case where transport control for transporting the light emitting panels between the light emitting panels stacked and accommodated in the standby area A1 is desired. In this case, the area between the light emitting panels stacked and accommodated in the standby area A1 is the placement area A3.

  Therefore, in order to realize such transport control, referring to FIG. 17, the sensor 204, transport rollers 310 and 311 and transport guides 503 and 504 are arranged in the lifting device 900 so that they can be lifted and lowered together.

Note that the control of the lifting device 900 is performed by the control unit 403.

  With reference to FIGS. 17 to 20, the conveyance control using the lifting device 900 will be described. Referring to FIGS. 17 and 18, the lifting device 900 waiting in FIG. 17 is lowered, and as shown in FIG. 18, the pair of insertion guides 801 includes the third light emitting panel 100 c and the fourth light emitting panel. It is located between 100d. Next, referring to FIG. 19, after the pair of insertion guides 801 are advanced to the light emitting panel side, the pair of insertion guides 801 are enlarged in the vertical direction, and the fourth light emitting panel 100 d is moved upward. At this time, the movable plate 602 is raised by the plunger 613 in conjunction with the expansion movement of the pair of insertion guides 801.

  Next, with reference to FIG. 20, a predetermined conveyance roller is driven to convey the first light emitting panel 100a between the third light emitting panel 100c and the fourth light emitting panel 100d. In this way, by storing the usage status of the plurality of light emitting panels 100a to 100b in the control unit 403, each of the light emitting panels 100a according to the usage status of the light emitting panels 100a to 100b based on the storage in the control unit 403. It is possible to determine the mounting position in the mounting area A3 of ~ 100b (arbitrary position between the stacked light emitting panels positioned in the standby area A1). As a result, it is possible to change and effectively use light emitting panels having different specifications according to the desires of the user.
