Abstract: A bank depository which provides a depositor with a validated receipt ticket evidencing that a deposit has been made, employs an envelope, in which the deposit is placed prior to insertion in the depository, having an unvalidated receipt ticket removably affixed to it. An outer surface of the depository has an opening through which the deposit is made leading to an internal chamber for storage of deposits and a slotted rotatable cylinder disposed between the opening and chamber normally positioned to prevent a deposit from being made until the receipt ticket is placed within a validator by the depositor. The cylinder then rotates to align its slot with the chamber to receive the deposit and allow it to pass through the chamber. Means are provided to sense the passage of the deposit to the chamber and to cause the receipt ticket to be validated in response thereto.
