An off-line terminal, located at an airline boarding gate processes composite tickets bearing a magnetic stripe. Processing includes: authenticating, verifying, recording, canceling, bursting into component sections and sorting. Operations are controlled, logged and interrelated in accordance with ticket content and operating programs. Structurally, a processing computer cooperates with magnetic stripe transducers, a printer, a burster, signal lamps and a plurality of document-direction gates to select and control the path of individual ticket components. An additional magnetic sensor for ticket components (e. g. boarding passes) enables control of passenger movements after initial clearance with ticket processing.

A heat transferable line printer used with a cassette carrying a heat transferable ink ribbon capable of being printed many times. The ink ribbon cassette comprises a case which is symmetrical to left and right, a pair of spools provided within the case, one spool serving as a winding spool whereas the other serving as a supply spool, both of which carry the ink ribbon, and a cylindrical hub gear supported on opposite ends of each of the spools and projected from a notch provided on the side of the case. The printer comprises a print unit and a feed unit which are pivotably connected with each other through a shaft, the feed unit including a platen extending parallel to the shaft, the print unit having a thermal head extending along the platen. The print unit comprises a pair of spool shafts selectively fitted into the hub projecting from the side of the ink ribbon cassette, the ink ribbon cassette being inversely mounted on the print unit.
