Abstract
A printer including a cover plate with a plurality of ribs connected along the bottom surface thereof to guide that portion of a recording medium which has passed by a print head through the discharge port of the printer. A release assembly controls and is operable for varying the level of pressure exerted by a pair of plates against a platen. A guide plate formed from portions having different sloped surfaces is detachably connected through clips to a frame of the printer. The printer also includes a mechanism for automatically setting a timing belt to a predetermined constant level of tension.
Claims12
A printer comprising:
- a platen;
- plate means for exerting different levels of pressure against the platen and including a first plate facing the platen and a second plate disposed adjacent to the first plate;
- release assembly means for controlling the level of pressure exerted by the plate means against the platen and including shaft means having at least one protrusion extending along the length of the shaft means for pressing against the second plate and control means for controlling the position of the shaft means relative to the plate means;
- said control means including release lever means and intermediate lever means, said intermediate lever means coupled to the shaft means;
- and
- a frame;
- wherein said intermediate lever means includes projection means for securing the intermediate lever means to the frame and, wherein the projection means includes claw means and the frame includes a hole, said claw means operable for being pushed through the hole and, once beyond the hole, locking itself to the frame.
