• a bill validator for validating bills inserted in the machine by users, and
• a cash box with a lock;
• and
• a rotation mechanism mounted to the machine interior and engaging said rotatable bill acceptor, such that the bill acceptor can rotate between at least (i) a bill insertion position in which the bill validator is accessible through the opening in the bill acceptor access door while the cash collection region is blocked from access by the external surface, and (ii) a cash removal position, rotationally separated from the bill insertion position, in which the cash box is accessible through the machine housing external surface while the bill validator is blocked from access by the external surface.
