A bundle bill/check acceptor includes a bundle receiving module to receive a bundle of bills/checks. The bundle of bills/checks is separated on a leaf-by-leaf basis by a transfer module. The accepter further includes an alignment module to align the individual bill/check, an escrow module to escrow a plurality of bills/checks, and a reject module to discharge a rejected bill/check or a bill/check escrowed by the escrow module requested to cancel the deposit thereof to the bundle receiving module. A normal bill and check are separately received in a cassette unit.
