Abstract

Abstract Recorder head for compound alphanumeric or code characters includes a cylindrical housing having front and rear slot guiding means, a plurality of flat and straight printing rods disposed in rows in mutual engagement and mounted in the front and rear slot guiding means, means having a type face located at the front end of said printing rods, respectively, electromagnet means coordinated with the printing rods for axially displacing the same into printing position, the printing rods being of equal length and being formed with reinforced sliding surface portions at mutually engaging regions thereof, the electromagnet means comprising pot-shaped magnets located one behind the other and formed with respective core bores, armature plates located adjacent and coordinated with the magnets, respectively, and also formed with respective bores, the plurality of printing rods extending in common through the core bores of the magnets and the bores of the armature plates, each of the printing rods having a stop operatively engageable by a respective armature plate in response to activation of a respective pot-shaped magnet for axially displacing the respective printing rod.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 169 words
Recorder head having a front end for compound alphanumeric or code characters comprising a housing having front and rear slot guiding means, a plurality of flat and straight printing rods disposed in rows and mounted in said front and rear slot guiding means, means having a type face located at the front end of said printing rods, respectively, electromagnet means cooperating with said printing rods for axially displacing the same into printing position, said printing rods being of equal length, said electromagnet means comprising magnets located one behind the other axially along said rods, means defining a core hole in each of said magnets, armature plates located adjacent to said magnets, each of said armature plates having an opening, said plurality of printing rods extending through said core holes of said magnets And said openings of said armature plates, each of said printing rods having a stop operatively engageable by a respective armature plate in response to activation of a respective magnet for axially displacing the respective printing rod.
Claim 2
Dependent Claim 169 words
Recorder head having a front end for compound alphanumeric or code characters comprising a housing having front and rear slot guiding means, a plurality of flat and straight printing rods disposed in rows and mounted in said front and rear slot guiding means, means having a type face located at the front end of said printing rods, respectively, electromagnet means cooperating with said printing rods for axially displacing the same into printing position, said printing rods being of equal length, said electromagnet means comprising magnets located one behind the other axially along said rods, means defining a core hole in each of said magnets, armature plates located adjacent to said magnets, each of said armature plates having an opening, said plurality of printing rods extending through said core holes of said magnets And said openings of said armature plates, each of said printing rods having a stop operatively engageable by a respective armature plate in response to activation of a respective magnet for axially displacing the respective printing rod.
Claim 3
Dependent Claim 25 words
Recorder head according to claim 1 wherein the type faces are substantially square-shaped and are adapted to form an alphanumeric character in a mosaic print.
Claim 4
Dependent Claim 18 words
Recorder head according to claim 1 wherein the type faces are lines, respectively, for forming a code character.
Claim 5
Dependent Claim 41 words
Recorder head according to claim 1 wherein the opening in said armature plates has a rectangular shape, and said stop of said printing rods comprises a projection therefrom which is wider than the diameter of said opening in said armature plates.
Claim 6
Dependent Claim 34 words
Recorder head according to claim 1 wherein said printing rods at the respective printing ends thereof are provided with line type having imprinting width of varying line thicknesses for printing a parallel line code.
Claim 7
Dependent Claim 22 words
Recorder head according to claim 5 wherein said line type is movably mounted in the printing plane on the respective printing rod.
Claim 8
Dependent Claim 31 words
Recorder head according to claim 5 wherein the magnets associated with the respective printing rods are constructed to have an output corresponding to the various line widths of said line type.
Claim 9
Dependent Claim 37 words
Recorder head according to claim 1 including a non-adhering sheet disposed between each of said magnets and the respective armature plates, and a stop washer disposed between the respective armature plates and the magnet located adjacent thereto.
