  The power feeding circuit 70 is a circuit for supplying power to the illumination unit 64 of the cultivation plate 60. As shown in FIG. 2, the power feeding circuit 70 includes a power source 71, a switch 72, a plate-side electric circuit 74, and a lead-out electric circuit 75. In addition, in FIG. 2, although the electric power feeding circuit 70 corresponding to one cultivation plate 60 arrange | positioned at one cultivation apparatus 20 is shown, the number (in this embodiment) of cultivation plates 60 which can be arrange | positioned in the cultivation apparatus 20 is shown. A plurality of power supply circuits 70 are also provided corresponding to (four stages). Moreover, about each of the some cultivation apparatus 20, the several electric power feeding circuit 70 is provided similarly. The switch 72 is a component that switches presence / absence of power supply from the power source 71 to the illumination unit 64, and is controlled by the control device 11. The plate-side electric circuit 74 is an electric circuit disposed on the lower surface of the cultivation plate 60 and can be moved together with the cultivation plate 60. The plate-side electric circuit 74 includes a wiring 63 a connected to the lead portion 63. The plate-side electric circuit 74 connects a plurality of illumination units 64 arranged on one cultivation plate 60 to each other (here, parallel connection), and connects the plurality of illumination units 64 and the lead-out units 63 and 63. The lead-out electric circuit 75 is an electric circuit drawn to the outside through the lead-out part 63 and the conduction part 46, and includes a wiring 46 a connected to the conduction part 46. The lead-out electrical path 75 connects the conduction part 46, the power source 71, the switch 72, and the conduction part 46 in series. In the power supply circuit 70, when the control device 11 turns on the switch 72 when the support claw 41 for conduction supports the cultivation plate 60, that is, when the conduction part 46 and the lead-out part 63 are conducted, Power is supplied from 71 to the illumination unit 64, and the illumination unit 64 emits light. Since switch 72 is arranged corresponding to each of cultivation plates 60 in cultivation device 20, control device 11 controls on / off of lighting part 64 for every cultivation plate 60 by switching switch 72 individually. Can do. However, the switch 72 of the some electric power feeding circuit 70 corresponding to the cultivation plate 60 in the cultivation apparatus 20 may be common. In this case, the control apparatus 11 can switch on / off the illumination part 64 of the some cultivation plate 60 collectively. Moreover, the power supply 71 may be common between the power supply circuits 70 corresponding to each stage or between the power supply circuits 70 corresponding to different cultivation apparatuses 20.

  Next, operation | movement of the cultivation system 10 of this embodiment comprised in this way, especially the process which transfers the cultivation plate 60 to an upper stage is demonstrated. When a predetermined period of time elapses at the uppermost stage of the cultivation apparatus 20, the control apparatus 11 unloads the cultivation plate 60 and moves the cultivation plate 60 inside the cultivation apparatus 20 to the upper stage, respectively. The process which carries in the cultivation plate 60 is performed. The control device 11 controls the moving lift 50 so as to move upward from below the cultivation plate 60. The support member 52 of the moving lift 50 ascends while supporting the bottom of the accommodating portion 61. The cultivation plate 60 moves upward with the accommodation portion 61 and the placement portion 65 integrated. Thereafter, the upper surface of the cultivation plate 60 abuts on the inclined surface 44 on the support claws 40 of the accommodating portion support portion 31 or the placement portion support portion 32. Then, as for the support nail | claw 40, the inclined surface 44 is pressed by the upper surface of the cultivation plate 60 to the retracted position side (FIG. 7 (a)). Subsequently, the cultivation plate 60 rises in the state of the support claw 40 in the retracted position (FIG. 7B). If the cultivation plate 60 passes, the support nail | claw 40 will be pressed by the biasing part 36, and will reach a support position (FIG.7 (c)). At this time, the moving lift 50 is raised by a predetermined distance to raise the placement portion 65 above the support claws 40 of the placement portion support portion 32. After that, when the moving lift 50 is lowered, the placement portion 65 is supported by the placement portion support portion 32, and the supported surface 62 of the accommodation portion 61 is supported by the support surface 43 of the support claw 40 of the accommodation portion support portion 31. It becomes a state. In addition, since the support claw 40 of the accommodating part support part 31 passes the notch part 66, it does not support the mounting part 65. Thus, the support mechanism 30 allows the cultivation plate 60 to move from below to above, does not allow the cultivation plate 60 to move downward, and has a simple structure that does not require a drive source. The upward movement and support can be performed.

  Here, in the state where the accommodating portion support portion 31 supports the accommodating portion 61 as shown in FIG. 7C, the lower surface of the drawer portion 63 and the protruding portion 46b of the conducting portion 46 are brought into contact with each other and are electrically connected. 11, the lighting unit 64 can be turned on and off. Moreover, when the movement lift 50 moves the cultivation plate 60 to the upper stage from this state, the drawer | drawing-out part 63 and the conduction | electrical_connection part 46 will space apart by raising the cultivation plate 60, and both conduction | electrical_connection is cancelled | released (FIG. 7 (d)).

  In addition, when the movement lift 50 moves the cultivation plate 60, the control apparatus 11 turns off the switch 72 of the electric power feeding circuit 70 corresponding to the cultivation plate 60 to be moved before the movement, and energizes the extraction circuit 75. Is preferably turned off. If it carries out like this, it can suppress that discharge arises between the drawer | drawing-out part 63 and the conduction | electrical_connection part 46 at the time of the raise start of the cultivation plate 60. FIG. In addition, the control apparatus 11 should just turn ON switch 72, after the movement of the cultivation plate 60 is completed, ie, when the cultivation plate 60 is supported by the accommodating part support part 31. FIG.

  Here, the correspondence between the components of the present embodiment and the components of the present invention will be clarified. The shelf 25 of this embodiment corresponds to the shelf of the present invention, the support claw 40 corresponds to the support, the conduction part 46 corresponds to the conduction part, and the conduction support claw 41 corresponds to the conduction support. . Further, the support surface 43 corresponds to the support surface, the inclined surface 44 corresponds to the inclined surface, the moving lift 50 corresponds to the moving lift, and the control device 11 corresponds to the energization control unit.

  The cultivation apparatus 20 according to the present embodiment described in detail above has a shelf 25 on which a plurality of cultivation plates 60 having a drawer 63 for pulling out the plate-side electric circuit 74 and on which a cultivation product P is placed are placed. I have. Moreover, the cultivation apparatus 20 has a plurality of support claws 40 that move between a support position for supporting the cultivation plate 60 and a retracted position for allowing the cultivation plate 60 to pass and are arranged on the shelf portion 25. And one or more of the plurality of support claws 40 are conduction support claws 41 having a conduction part 46 that conducts with the drawing part 63 of the cultivation plate 60 supported at the support position. In this cultivation apparatus 20, since the support nail | claw 40 moves between a support position and a retreat position, a support body can support the cultivation plate 60 so that a movement is possible. And in the state which the support nail | claw 41 for conduction supported the cultivation plate 60 in the support position, the conduction | electrical_connection part 46 of the support nail | claw 41 for conduction | electrical_connection and the drawer | drawing-out part 63 of the cultivation plate 60 conduct | electrically_connect. Thereby, the cultivation apparatus 20 can draw out the extraction electric circuit 75 from the plate side electric circuit 74 of the cultivation plate 60 to the outside through the conduction part 46. On the other hand, in cultivation device 20, if cultivation plate 60 moves, drawer part 63 and conduction part 46 will be separated in connection with this, and conduction will be canceled. In this way, the cultivation device 20 automatically switches between the conduction and release of the drawing portion 63 and the conduction portion 46 depending on whether or not the cultivation plate 60 is supported by the support claws 40. Therefore, the cultivation apparatus 20 can easily connect and disconnect the plate-side electric circuit 74 of the cultivation plate 60 and the extraction electric circuit 75 drawn from the cultivation plate 60. Thereby, for example, the labor of the operator can be reduced as compared with the case where the worker attaches / detaches the connector and connects and disconnects the plate-side electric circuit 74 and the extraction electric circuit 75. Further, for example, when a wiring (for example, the wiring 46a) is directly attached to the cultivation plate 60 and the electric circuit is drawn to the outside, the wiring is pulled with the movement of the cultivation plate 60. For example, there is a case where the wiring is tangled or the movement of the cultivation plate 60 is restricted by the length of the wiring. In the cultivation apparatus 20, such a problem is difficult to occur.

  Moreover, in the support claw 41 for conduction, the conduction part 46 is disposed on the support surface 43 that supports the cultivation plate 60 from below at the support position. Therefore, while the conduction support claws 41 support the cultivation plate 60, the drawing portion 63 and the conduction portion 46 can be more reliably conducted by the weight of the cultivation plate 60.
