搬入 and 搬出: moving goods into and out of a building
Compare moving exhibits into a building with moving them out. Keep the specified building's boundary separate from commercial purchasing.
Move goods into the site
搬入, read はんにゅう, means moving into a site. 展示品は開館前に裏口から搬入された。 says that the exhibits were brought in through the rear door before opening.
The scene concerns movement into the exhibition place. 裏口から gives the entry route, not a report that the exhibits were newly purchased.
Move goods out of the site
搬出, read はんしゅつ, means moving out. 展示品を閉館後に建物から搬出した。 says that the exhibits were moved out of the building after closing.
建物から supplies the starting place. Keep the same building's inside and outside as the comparison reference.
Announcing a time and completing movement
大型の机を搬入する時間を管理人に伝えた。 says that someone told the manager the time for bringing in the large desk. The completed action is communicating the time.
Announcing the move-in time does not establish a completed move. Focus on crossing the site boundary rather than stock or ordered quantities.
Does 展示品を搬出した。 from a building mean the exhibits were newly purchased?
Show the answer and why
No. It reports moving them out of the building. A purchase needs separate information.
