The wall portion 18b of the third member 18 isolates the optical devices 44 stored in the adjacent spaces S from each other. That is, the third member 18 is an example of a separating member.

As shown in FIG. 12, the optical device 44 is stored with the prism fixing plate 452 facing the space S2. At this time, the panel unit 445 (not shown in FIG. 12) is in contact with the first member 14. On the other hand, the prism 444 is in contrast to the prism fixing plate 452.
Since it is lower than the panel unit 445, it is not in contact with the first member 14. The first member 14 is
The optical device 44 is held in contact with the optical device 44. That is, the first member 14 is an example of a bottom member.
As shown in FIG. 13, the cable 450 is stored in the space S2. The height L53 of the third member 18 is defined as a height at which the cable 450 can be stored.

When the packaging box 10 is closed, as shown in FIG. 14, the optical device fixing portion 20 b of the fourth member 20 is in contact with the prism fixing plate 452 on substantially the entire surface of the prism fixing plate 452 of the optical device 44. Note that the length L64 (see FIG. 10) of the optical device fixing portion 20b is the length in the direction of the vertical length L42 (see FIG. 8) of the second member 16 through-hole 16a when the packaging box 10 is closed. It is defined as a length that can cover more than half and does not prevent the cable 450 of the optical device 44 from being stored in the space S2.

The packaging box 10 is configured as described above.
As described above, the optical device 44 can be held by the first member 14 being in contact with the panel unit 445. This means that in the packaging box 10, the prism 444 is stored in the vicinity of the first member 14, but does not contact the first member 14. For this reason, the center of gravity of the optical device 44 is lowered in the packaging box 10. Further, the optical device 44 is not damaged by other members.
Further, the optical device fixing portion 20b of the fourth member 20 is provided on the substantially entire surface of the prism fixing plate 452.
Contacts the prism fixing plate 452 to fix the optical device 44. This means that the area where the prism fixing plate 452 contacts to fix the optical device 44 is large. For this reason, the optical device 44 can be firmly fixed in the packaging box 10. Further, since the prism fixing plate 452 is not in contact with the prism 444, the prism 444 is not damaged.
Thereby, according to the packaging box 10, the optical device 44 is obtained without damaging the prism 444.
Can be fixed sufficiently.

Moreover, since the packaging box 10 has the wall part 18b of the 3rd member 18, the optical apparatuses 44 do not contact in the packaging box 10. FIG.
Thereby, it is possible to prevent the optical devices 44 from coming into contact with each other due to contact with each other.

Furthermore, since the side surface portion of the packaging box 10 is blocked from the outside by the pedestal portion 20a of the fourth member 20, it is possible to prevent foreign matters such as dust from entering the packaging box 10 from the outside.
Further, since the pedestal portion 20a is provided integrally with the fourth member 20, there is no need to increase the number of parts of the packaging box 10.
Thereby, although it is not necessary to increase the number of parts of the packaging box 10, it is possible to prevent foreign matters such as dust from entering the packaging box 10.
