(57) An automatic/manual shuttle mechanism is used to open and close the bail mechanism
which holds a print sheet against the platen roller (36) of a typewriter/printer.
The shuttle mechanism includes a shuttle member (218) fitted with a slot (224). The
slot rides (or shuttles) against a pin (246) which is mounted to the frame of the
typewriter/printer. The shuttle mechanism is coupled to the bail mechanism. In an
automatic mode of operation, a motor/crank assembly (236, 238, 234, 232, 229, 230)
drives the shuttle mechanism (218). In a manual mode of operation, a manual lever
(216) drives the shuttle member.
