A device comprising a document recycle box and a document validator, wherein the document recycle box is removably attached to a document validator, said document recycle box comprising: a housing, a cover rotatably attached to the housing, a convey belt device of a recycle conveyor device attached to one of the housing and cover along one side of a recycle pathway that extends within the housing, a plurality of rollers or an opposite convey belt device of the recycle conveyor device attached to the other of the housing and cover along the other side of the recycle pathway on the opposite side of the convey belt device for transporting documents along the recycle pathway in cooperation with the convey belt device, and a drum device that has a single or a plurality of drums (41, 42) rotatably disposed within the housing, wherein the drum device winds up the documents supplied through the recycle pathway for storage of the documents within the drum device, the drum device unwinds the stored documents to discharge the documents out of the housing through the recycle pathway by the recycle conveyor, the cover is released from the housing to move the recycle conveyor away from the rollers or the opposite convey belt device, said document validator comprising: a case having a trifurcate intersection, a shuttle pathway, a reserve pathway and a recycle pathway each connected to the trifurcate intersection, and a turning device operated to have a document crossing over from one to another of the shuttle, reserve and recycle pathways (5, 10, 11) at the trifurcate intersection, the recycle pathway comprises a slit formed between the housing and cover, and a lane formed between the drum device and recycle pathway above the slit and communicated with the slit, the recycle conveyor device transports the documents along the recycle pathway that extends within the housing from the trifurcate intersection of the document validator, and the drum device is rotatably disposed within the housing for winding up the documents supplied from the intersection of the validator by the recycle conveyor device through the recycle pathway for storage of the documents within the drum device, and also for unwinding the stored documents to discharge the documents to the intersection of the validator through the recycle pathway by the recycle conveyor device. said document recycle box comprising: a housing, a cover rotatably attached to the housing, a convey belt device of a recycle conveyor device attached to one of the housing and cover along one
