[0021] 5, when the first packing box 21 is loaded on the upper surface 30a of the base member 30, the first packing box 21 is slid from the front to the rear in a state in which the flange portion 52a of the leg portion 52 provided at the left end engages with the protruding portion 51a of the left engaging rail 51 of the pair of left and right engaging rails 51 provided on the upper surface 30a of the base member 30, and the flange portion 52a of the leg portion 52 provided at the right end engages with the protruding portion 51a of the right engaging rail 51 of the pair of left and right engaging rails 51 provided on the upper surface 30a of the base member 30. As a result, the first packing box 21 engages with the upper surface 30a of the base member 30 and is loaded on the upper surface 30a of the base member 30.

[0022] When the first packing box 21 is loaded onto the upper surface 21b of a different first packing box 21, the upper surface 22b of the second packing box 22, or the upper surface 23b of the third packing box 23, the first packing box 21 is slid from front to rear with the flange portion 52a of the leg 52 provided at the left end engaging with the protrusion 51a of the left engaging rail 51 of a pair of left and right engaging rails 51 provided on the upper surface 21b of the different first packing box 21, the upper surface 22b of the second packing box 22, or the upper surface 23b of the third packing box 23, and the flange portion 52a of the leg 52 provided at the right end engaging with the protrusion 51a of the right engaging rail 51 of the pair of left and right engaging rails 51 provided on the upper surface 21b of the different first packing box 21, the upper surface 22b of the second packing box 22, or the upper surface 23b of the third packing box 23. As a result, the first packing box 21 engages with the upper surface 21b of a different first packing box 21, the upper surface 22b of the second packing box 22, or the upper surface 23b of the third packing box 23, and is loaded on the upper surface 21b of the different first packing box 21, the upper surface 22b of the second packing box 22, or the upper surface 23b of the third packing box 23.

[0023] When loading the second packing box 22 on the upper surface 30a of the base member 30, the second packing box 22 is slid from the front to the rear with the flange portion 52a of the leg portion 52 provided at the left end engaging with the protruding portion 51a of the left engaging rail 51 of the pair of left and right engaging rails 51 provided on the upper surface 30a of the base member 30 and the flange portion 52a of the leg portion 52 provided at the right end engaging with the protruding portion 51a of the right engaging rail 51 of the pair of left and right engaging rails 51 provided on the upper surface 30a of the base member 30. As a result, the second packing box 22 engages with the upper surface 30a of the base member 30 and is loaded on the upper surface 30a of the base member 30.

[0024] When the second packing box 22 is loaded onto the upper surface 21b of the first packing box 21, the upper surface 22b of a different second packing box 22, or the upper surface 23b of the third packing box 23, the second packing box 22 is slid from front to rear with the flange portion 52a of the leg 52 provided at the left end engaging with the protrusion 51a of the left engaging rail 51 of a pair of left and right engaging rails 51 provided on the upper surface 21b of the first packing box 21, the upper surface 22b of the different second packing box 22, or the upper surface 23b of the third packing box 23, and the flange portion 52a of the leg 52 provided at the right end engaging with the protrusion 51a of the right engaging rail 51 of the pair of left and right engaging rails 51 provided on the upper surface 21b of the first packing box 21, the upper surface 22b of the different second packing box 22, or the upper surface 23b of the third packing box 23. As a result, the second packing box 22 engages with the upper surface 21b of the first packing box 21, the upper surface 22b of a different second packing box 22, or the upper surface 23b of the third packing box 23, and is loaded on the upper surface 21b of the first packing box 21, the upper surface 22b of a different second packing box 22, or the upper surface 23b of the third packing box 23.

[0025] When loading the third packing box 23 on the upper surface 30a of the base member 30, the third packing box 23 is slid from the front to the rear in a state in which the flange portion 52a of the leg portion 52 provided at the left end engages with the protruding portion 51a of the left engaging rail 51 of the pair of left and right engaging rails 51 provided in the left region of the upper surface 30a of the base member 30, among the two pairs of left and right engaging rails 51 provided on the upper surface 30a of the base member 30, and the flange portion 52a of the leg portion 52 provided at the right end engages with the protruding portion 51a of the right engaging rail 51 of the pair of left and right engaging rails 51 provided in the right region of the upper surface 30a of the base member 30, among the two pairs of left and right engaging rails 51 provided on the upper surface 30a of the base member 30. As a result, the third packing box 23 engages with the upper surface 30a of the base member 30 and is loaded on the upper surface 30a of the base member 30.

[0026] In this manner, each shipping box 20 can be loaded onto the base member 30 by engaging the legs 52 with the engaging rails 51 of the base member 30 or a different shipping box 20 .

[0027] Therefore, the first packing box 21 and the second packing box 22 can be loaded on the base member 30 by engaging with the base member 30, and the first packing box 21 and the second packing box 22 can be loaded on the upper surface 21b, 22b of either the first packing box 21 or the second packing box 22 by engaging with either the lower first packing box 21 or the lower second packing box 22. As a result, packing boxes 20 of different heights can be loaded in the vertical direction by engaging with the base member 30 and the lower packing box 20, so that the packing boxes 20 of different heights can be combined with a high degree of freedom in the vertical direction and loaded on the base member 30 without moving relative to the base member 30 and the lower packing box 20.

[0028] <Panel material> As shown in FIG. 3, the panel members 40 are connected to the rear end of the base member 30 in the vertical direction. The panel members 40 include a first panel member 41 and a second panel member 42. The first panel member 41 and the second panel member 42 are substantially rectangular parallelepipeds extending in the vertical and horizontal directions with a predetermined thickness in the front-rear direction. In this embodiment, the first panel member 41 and the second panel member 42 have the same dimensions. The height dimension of the first panel member 41 and the second panel member 42 is three times the unit height dimension H1, that is, 3×H1. Therefore, the height dimension of the first panel member 41 and the second panel member 42 is the same as the height dimension of the first packing box 21. The width dimension of the first panel member 41 and the second panel member 42 is about twice the width dimension W1, and has a width dimension W4 that is substantially the same as the width dimension W3. The first panel member 41 is connected to the base member 30 in a state where it is placed on the rear end of the upper surface 30a of the base member 30. The second panel member 42 is detachably connectable to the first panel member 41 or to a different second panel member 42 in the vertical direction.

[0029] The first panel member 41 and the second panel member 42 have claws 40a at the upper end of the left and right side surfaces. The second panel member 42 has a fastening lever 40b at the lower end of the left and right side surfaces, which can be engaged with the claws 40a. The fastening lever 40b of the second panel member 42 is engaged with the claws 40a of the first panel member 41 or the second panel member 42 arranged below the second panel member 42. As a result, the second panel member 42 is connected to the first panel member 41 or the second panel member 42 arranged below the second panel member 42 in the vertical direction. FIG. 3 shows an example in which the second panel member 42 is connected to the upper surface of the first panel member 41, and a different second panel member 42 is connected to the upper surface of the second panel member 42. In this way, FIG. 3 shows three panel members 40, specifically one first panel member 41 and two second panel members 42, connected in the vertical direction.

[0030] An upper connector 40c is provided on the upper surfaces of the first panel member 41 and the second panel member 42, and a lower connector 40d that is electrically conductive with the upper connector 40c is provided on the lower surface of the second panel member 42. When the second panel member 42 is connected above the first panel member 41 or a different second panel member 42, the lower connector 40d is electrically conductive with the upper connector 40c of the first panel member 41 or the second panel member 42 that is disposed below the second panel member 42. This electrically connects the multiple panel members 40 that are connected to the rear end of the base member 30 in the up-down direction to each other.

[0031] A cap CP is fitted to the top connector 40c of the panel member 40 arranged at the topmost stage. The cap CP can prevent foreign matter such as water or dust from entering the top connector 40c of the panel member 40 arranged at the topmost stage and can prevent the top connector 40c of the panel member 40 arranged at the topmost stage from being electrically connected to an unintended member.

[0032] <Conduction between packing box and panel material> As shown in FIG. 6(a), the panel member 40 is provided with a panel-side connector 400. The panel-side connector 400 has a base portion 400a, a connector terminal 400b fixed to the base portion 400a so as to face forward, and a pair of left and right positioning pins 400c fixed to the base portion 400a so as to face forward with the connector terminal 400b sandwiched therebetween in the left-right direction. The base portion 400a is supported by the panel member 40 by a pair of left and right coil springs 400d. The front surface of the panel member 40 is open in an area overlapping with the connector terminal 400b and the positioning pin 400c when viewed from the front-rear direction. Therefore, the panel-side connector 400 is provided on the panel member 40 so that the connector terminal 400b and the positioning pin 400c can be accessed from the front of the panel member 40.

[0033] As shown in Fig. 6(b), a packing box side connector 200 capable of electrical connection with the panel side connector 400 of the panel member 40 is provided on the rear surface of each packing box 20. The packing box side connector 200 has a connector terminal 200a fixed to the rear surface of the packing box 20 so as to face rearward, and a pair of left and right bushes 200b fixed to the rear surface of the packing box 20 so as to face rearward and sandwich the connector terminal 200a in the left-right direction. The bushes 200b are shaped so as to be able to fit into the positioning pin 400c of the panel side connector 400.

[0034] 6(c), the packing box side connector 200 of each packing box 20 is connected to the panel side connector 400 by fitting the positioning pin 400c and the bush 200b of the panel side connector 400, whereby the connector terminal 200a of the packing box side connector 200 and the connector terminal 400b of the panel side connector 400 are connected and electrically connected to the panel side connector 400. At this time, the pair of left and right coil springs 400d provided on the panel member 40 absorbs dimensional errors of each packing box 20 and each panel member 40, assembly errors of the multiple panel members 40, rattles between the engaging rail 51 and the leg 52, and the like, so that the packing box side connector 200 of each packing box 20 can be connected to the panel side connector 400 in a state of reliable electrical connection.

[0035] 3 and 9, when the legs 52 of the packing box 20 engage with the engagement rails 51 provided on the upper surface 30a of the base member 30 and the packing box 20 is loaded on the upper surface 30a of the base member 30, the packing box side connector 200 is provided at a position a first distance L1 above the upper surface 30a of the base member 30 in the vertical direction. Therefore, in this embodiment, the packing box side connector 200 is provided at a position a first distance L1 above the lower end of the packing box 20, i.e., the lower end of the legs 52, in the vertical direction. Also, the packing box side connector 200 is provided at a position a second distance L2 from the left surface of the packing box 20 in the left-right direction.

[0036] The first panel member 41 is provided with four panel-side connectors 400. The second panel member 42 is provided with four panel-side connectors 400, similar to the first panel member 41.

[0037] The panel side connector 400 provided on the first panel member 41 has a panel side upper left connector 401a provided in the upper left region of the front surface of the first panel member 41, a panel side lower left connector 401b provided in the lower left region of the front surface of the first panel member 41, a panel side upper right connector 401c provided in the upper right region of the front surface of the first panel member 41, and a panel side lower right connector 401d provided in the lower right region of the front surface of the first panel member 41.

Similarly, when the second panel member 42 is adjacent to and above the first panel member 41 and connected to the first panel member 41, and the legs 52 of the second shipping box 22 engage with the engagement rail 51 provided in the right area of ​​the top surface 30a of the base member 30 so that the second shipping box 22 is loaded on the top surface 30a of the base member 30, and then the first shipping box 21 or a different second shipping box 22 is loaded on the top surface 22b of the second shipping box 22 so that the left and right legs 52 engage with a pair of left and right engagement rails 51 provided on the top surface 22b of the second shipping box 22, the panel side upper right connector 402c is connected to the shipping box side connector 200 of the first shipping box 21 or second shipping box 22 loaded on the top surface 22b of the second shipping box 22.

[0048] Therefore, when the second panel member 42 is connected to the first panel member 41 adjacently above the first panel member 41 and the legs 52 of the second packing box 22 engage with the engagement rails 51 provided in the left area of ​​the top surface 30a of the base member 30 so that the second packing box 22 is loaded on the top surface 30a of the base member 30, and then the first packing box 21 or a different second packing box 22 is loaded on the top surface 22b of the second packing box 22 so that the left and right legs 52 engage with the pair of left and right engagement rails 51 provided on the top surface 22b of the second packing box 22, the packing box side connector 200 of the first packing box 21 or second packing box 22 loaded on the top surface 22b of the second packing box 22 is connected to and conductively connected to the panel side upper left connector 402a of the second panel member 42 connected to the first panel member 41 adjacently above the first panel member 41. Similarly, when the second panel member 42 is connected to the first panel member 41 adjacently above the first panel member 41 and the legs 52 of the second packing box 22 engage with the engagement rail 51 provided in the right area of ​​the top surface 30a of the base member 30 so that the second packing box 22 is loaded on the top surface 30a of the base member 30, and the first packing box 21 or a different second packing box 22 is loaded on the top surface 22b of the second packing box 22 so that the left and right legs 52 engage with the pair of left and right engagement rails 51 provided on the top surface 22b of the second packing box 22, the packing box side connector 200 of the first packing box 21 or second packing box 22 loaded on the top surface 22b of the second packing box 22 is connected to and conductively connected to the panel side upper right connector 402c of the second panel member 42 connected to the first panel member 41 adjacently above the first panel member 41.

[0049] As a result, even if multiple packing boxes 20 of different heights are stacked vertically on the base member 30, such as from the bottom up, for example, the first packing box 21 and the first packing box 21, the first packing box 21 and the second packing box 22, the second packing box 22 and the first packing box 21, and the second packing box 22 and the second packing box 22, the packing box side connector 200 of each packing box 20 can be electrically connected to the panel side connector 400 of the first panel member 41 or the second panel member 42, and each packing box 20 can receive power via the first panel member 41 or the second panel member 42.

The second panel member 42 can be connected in the vertical direction above the first panel member 41 that connects to the base member 30. Therefore, even when multiple shipping boxes 20 are stacked in the vertical direction and loaded on the base member 30, the shipping box side connector 200 of each shipping box 20 can be electrically conductive with the panel side connector 400 of the first panel member 41 or the second panel member 42, and each shipping box 20 can receive power via the first panel member 41 or the second panel member 42.

[0051] Furthermore, as described above, when the second panel member 42 is connected above the first panel member 41 or a different second panel member 42, the lower connector 40d is electrically connected to the upper connector 40c of the first panel member 41 or the second panel member 42 arranged below the second panel member 42, thereby electrically connecting the multiple panel members 40 connected in the vertical direction to the rear end of the base member 30 to each other. As a result, since power can be supplied to each packing box 20 via the panel members 40, it is not necessary for each packing box 20 to have a configuration for mutual conduction between the packing boxes 20, and the packing boxes 20 can be configured simply.

[0052] Each packing box 20 operates, for example, the electronic lock described above by power supplied through the first panel member 41 or the second panel member 42. Also, each packing box 20 may open and close the door members 21a, 22a, 23a by power supplied through the first panel member 41 or the second panel member 42.
