Abstract
Abstract Guide means for a printer including two conductor members for guiding a paper web out of the printer. In a first position, the conductor members form a tightly fitting cover for a rectangular hole in a casing associated with the printer, where the paper web is conducted in a gap, tapering in the direction of paper advance, between the conductor members and out of the printer. In a second position of the conductor members, a rectangular opening is formed behind the members, making the paper web accessible for feeding into a tractor feeder of the push-pull traction feed type.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
243 words
In a printer of the type having a casing and a tractor feed mechanism for advancing a printing medium to a position on a platen where printing takes place, and operable in a first mode in which the printing medium is directly discharged from the printer, through an opening in said casing, after printing takes place, and a second mode in which the printing medium is brought back into engagement with the tractor feed mechanism after printing for subsequent discharge from the printer, apparatus for automatically guiding the printing medium to one of two positions respectively related to the mode of operation of the printer, comprising: a first plate disposed in said opening and movable between a first position in which said plate closes at least a portion of said opening to inhibit access to said tractor feed mechanism, and a second position which provides access to said mechanism through said portion of said opening; and a second plate disposed in said opening and movable between a first position in which said second plate cooperates with said first plate in its first position to form a tapering gap into which the printing medium is automatically advanced after printing and through which the printing medium is directly discharged from the printer, and a second position in which said second plate cooperates with said first plate in its second position to automatically guide said printing medium to said portion of said opening for access thereto.

Claim 4
Dependent Claim
24 words
The apparatus of claim 1 wherein said first and second plates substantially enclose said opening when said plates are in their respective first positions.
