自動改札機（じどうかいさつき）： Automatic ticket gate

This week I learnt the word for automatic ticket gate: 自動改札機（じどうかいさつき). I also found out that the first automatic ticket gate in the world was installed at Kita-Senri station on the Hankyu Line in 1967. This was introduced to lesson the connection at station during rush hour, as the station is next to Osaka University.
