ABSTRACT:
The printer records images in the form of dots on electrical discharge-sensitive paper. Three groups of five styli are mounted on a rotor. The paper is in strip form and is fed continuously through a curved guide in a direction perpendicular to the plane of rotation of the rotor, so that the paper is wrapped part way around the rotor as it moves past. Characters are formed from a five dot by seven dot matrix. This invention provides means for automatically retracting the styli away from the paper when the rotational speed of the rotor drops below a pre-determined minimum level and, of course, when the rotor stops. This facilitates removal of the rotor from the printer, and also facilitates feeding a new strip of paper into the printer. Means also are provided for adjusting the axial position of each group of styli merely by turning one or more screws. The screws are easily accessible without removing the rotor. Simple screw adjustment means also are provided for adjusting the radial extent of the styli to compensate for wear of the styli, and align the characters produced by the printer. Means also are provided for easily removing and replacing the rotor in the printer, thus facilitating repairs or adjustments.
