Serial printer provided with cutter, the printer being of the type in which printing is performed by a printing head mounted on a carriage sliding on guides parallel to the printing line and a continuous printing support moves perpendicularly to the direction of such guides leaning against a substantially vertical platen. A rotating cutter is lever-mounted on the carriage over the printing head in a position very close to the printing line and it can be actuated in order to partially overlap a cutting edge of the platen, the edge being parallel to the printing line. Owing to the printing head movement along the printing line, the rotating cutter when actuated operates the transversal cutting of the continuous form. The cut form is disposed in a collecting drawer behind the platen owing to the movement imposed by the rotating cutter and to the reduced thickness of the platen which constitutes a drawer wall. A transparent elastic leaf coupled to the lever on which the rotating cutter is mounted assures the form steadiness during the cutting by pressing it against the platen near the cutting zone. It further provides an elastic reaction which brings the rotating cutter in rest position when it is not actuated to be in cutting position. The leaf does not hamper print visibility nor does it hamper the loading of the form in the printer when the carriage is at its end of travel position.

Serial printer provided with cutter

A serial printer is disclosed where the printing is performed by a printing head (22) mounted on a carriage (21) movable along the printing line, a transparent leaf (36) mounted on the carriage presses the printing support (25) (paper) against a platen (24) around the zone where the impression is performed thus considerably reducing the noise and vibration generated by the printing support vibrations during the printing. Preferably, the leaf is provided with a window (45) wherein the impression is performed in order to press the printing support against the platen all around the print zone. As the leaf is transparent, it does not preclude the visibility of what is printed. Besides, as the leaf is mounted on the carriage, when the carriage is in its travel position, the leaf does not interfere with the loading of the printing support in the printer.

Antinoise device for impact serial printers

The present invention relates to document positioning and feeding apparatus for high speed printers, such as normally associated with data processing systems. The document feeding apparatus is particularly adapted to provide high quality, high speed printing of stock consisting of multiple pages or non-uniform thicknesses. It is useful for the printing of savings-books, checks and statement of account forms. The apparatus utilizes a unique coupling means to maintain equal and opposite rotation of the feeding elements and to substantially reduce relative rotary motion between the feeding elements during the feeding of stock into the printer. Novel support means allow the feeding elements to accommodate stock having a different thickness for one part of the stock compared to another part.
