In some stations, automatic ticket machines are installed inside the automatic ticket gate; passengers can buy tickets with cash on the platform by passing the ticket gate, but they don't need to return to the automatic ticket gate in order to pass the ticket.
一部の駅では自動改札の内側に自動券売機があるが、現金の場合は改札の横を通り抜けてホームに入り切符を購入すればよい（戻って自動改札に通す必要はない）
