Therefore, when the lock plate is in the unlocked position, the latch can be switched to a retractable state regardless of the position of the trigger. The door can be opened simply by pulling it out.For example, it is possible to hold the luggage with one hand and open the door with the other hand, making it easier to post luggage Can Nau. As a result, it is possible to avoid a situation in which luggage cannot be posted in the home delivery box as in the related art, and it is possible to improve the usability.

According to the third aspect of the present invention, the lock mechanism includes a posting display member for displaying the current set position of the lock plate outside the door in conjunction with the switching operation of the locking set button. Therefore, whether the lock plate is set to the lock position or the unlock position by the lock set button can be determined by looking at the posting display member from the outside of the door, and therefore, the lock plate is set to the lock position. When the door is closed in this state, it is known that the package is actually posted in the delivery box, and when the door is closed with the lock plate set to the unlock position, the delivery box is It turns out that no luggage has been posted inside, and the unnecessary operation of the housekeeper opening the door and checking the inside of the delivery box is unnecessary. Also it can be eliminated fetch forgotten luggage at the same time. On the other hand, when the courier posts the luggage and the door is closed with the lock plate set to the locked position, the luggage has already been posted in the courier box by the posting display member, Can be determined at a glance, and when the door is closed with the lock plate set to the unlocked position, it can be determined at a glance that luggage can be posted.
The courier does not have to perform the useless operation of grasping the door handle and checking whether the luggage can be posted.
