ABSTRACT:
A vertical carrier receiving tube at the teller station in a pneumatic tube system for banking is provided with a door upon which the carrier arrives from the customer kiosk station. The door is counterbalanced so that upon arrival of the carrier its weight opens the door to display the carrier and upon its removal the door automatically recloses, thus eliminating the need for any motor drive to open and close the door.
