In this case, it is possible to reduce the possibility that the upper cushioning materials 31a and 31b fall off from the upper side of the digital multifunction peripheral 11.

  Next, the case where the packing case 19 packed in this way is opened will be described. FIG. 10 is a flowchart showing a typical process flow when unpacking the digital multi-function peripheral 11 packed in the packing case 19.

  Referring to FIG. 10, first, joint members 26a to 26d inserted through side wall through holes 47a to 47d and bottom wall through holes 25a to 25d at the time of packing are removed (S21). That is, the state where the bottom lid 21 and the case main body 41 are joined is released.

  Next, the case main body 41 is pulled out from the upper side (S22). In this case, since the two upper cushioning materials 31a and 31b are both attached to the inner flaps 51b and 51d, the upper cushioning materials 31a and 31b are pulled out from the upper side of the case body 41 together with the case body 41. In this case, it is not necessary to cut the sealing tape.

  Thereafter, the digital multifunction peripheral 11 placed on the bottom lid 21 is taken out through the lower cushioning materials 32a and 32b (S23). In this way, the unpacking operation is completed.

  According to such a configuration, the upper cushioning materials 31a and 31b are attached to the protrusions 54a to 54e provided with the recesses 34a to 34e as the fitting portions on the inner flaps 51b and 51d. Then, at the time of unpacking, when pulling out the case main body 41, the case main body 41 and the upper cushioning materials 31a and 31b can be removed together. Moreover, the work which cuts the sealing tape which sealed the outer flap is also unnecessary. In this case, since the recessed portions 34a to 34e as the fitting portions provided in the upper cushioning materials 31a and 31b are fitted and attached to the protruding portions 54a to 54e provided in the inner flaps 51b and 51d, the case main body portion 41 is mounted. When pulling out, the possibility that the upper cushioning materials 31a and 31b may fall out of the case body 41 can be greatly reduced. Further, when the case main body 41 is pulled out, the upper cushioning materials 31a and 31b remain on the upper side of the digital multifunction peripheral 11, and the operator does not need to press the upper cushioning materials 31a and 31b by hand. . Therefore, according to such a packing case 19, workability can be improved.
