Abstract: A money receiving and disbursing machine being adapted to circulate and use only one predetermined denomination of bank notes received in the machine for disbursing. Bank notes received in the machine other than the predetermined denomination of bank notes are introduced in the received money storage section for storing. In the money receiving process, bank notes are introduced into the machine through the transaction window device. The bank notes are introduced and stored in the circulating money storage section or the received money storage section in accordance with the denominations thereof through the discriminating route and distributing route. In money disbursing process, bank notes are picked out of the circulating money storage section or disbursing money storage section in accordance with a monetary amount of a disbursement order and introduced into the temporary hold section through the money disbursing route and the common route. The bank notes are disbursed through the transaction window device.

Abstract: A circulation-type bill receiving and dispensing machine reuses received bills for dispensing. It has a bill receiving and dispensing port and operating section at both sides of the machine. The bill receiving and dispensing machine includes separate bill discriminating sections each of which is arranged on each received-bill transferring route of the bill receiving and dispensing ports of the two sides for the exclusive use of that port. Thus the bill receiving and dispensing machine of the present invention can be operated at the same time from both sides. Accordingly, a customer can deposit bills at any time even if the machine is being operated in the bill receiving mode by the teller.

Abstract: A bill receiving and dispensing machine of "specific type of bill circulation-type" which can reuse, as bills for dispensation, only one specific type of bills among all types of received bills. According to the machine of the present invention, only one type of bills among all types of received bills is circulated through a circulating-bill pooling section for reuse as bills for dispensation and the dispensation bills other than the circulating bills are held in a dispensation bill container and the received bills and the dispensation bills are held in three limited sections, i.e. a circulating-bill pooling section, a received-bill container and a dispensation bill container. This makes it possible to eliminate the special bill pooling sections and the bill feeding-out mechanisms which are used in the conventional machines and therefore to simplify the mechanism and to reduce the noise during the operation thereof.
