  • a pair of printing rods of equal length which extend through core bores formed in pot-shaped electromagnets that are disposed one behind the other and through bores formed in armature plates associated with the electromagnets, a respective armature plate associated with one of the pot-shaped magnets being operatively connected with a respective stop of one of the printing rods for axially displacing the latter, the printing rods being provided with line type at the printing end thereof, the line type having a printing width individually and in combination one with the other which embody respectively different line thicknesses for a parallel line code.
  • Such an apparatus is necessary in the printing of coded data in order to be able to evaluate the data by machine, such as in electronic data processing or EDP installations. In such a case, assurance must be provided that the printed code picture is free of error and, especially, that the individual lines are inked so as to be readable throughout without trouble.
  • recorder head for recording code characters by line printing comprising a cylindrical housing having forward and rearward guide means, a pair of axially displaceable printing rods of substantially equal length disposed adjacent and parallel to one another and guidable by the forward and rearward guide means, means having a line type face located at the forward end of the printing rods, respectively, the line type of the printing rods having a printing width individuallyand in combination one with the other which embody respectively different line thicknesses for a parallel line code, electromagnet means comprising pot-shaped printing magnets disposed one behind the other and formed with respective core bores, armature plates located adjacent and coordinated with the printing magnets, respectively, the armature plates being also formed with respective bores, the pair of printing rods extending together through the core bores of the printing 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
  • the armature plate cooperating with the restoring spring for displacing the printing rods to the nonprinting position also cooperates with one of the printing springs for displacing the printing rods to the printing position.
  • the printing rods in the printing position, are in en gagement with a record carrier, the printing rods being displaceable into engagement with the record carrier over a greater distance than the distance traversed by the armature plates for driving the printing rods into printing position.
  • the line type at the forward end of the printing rods is trapezoidal in cross section and has printing surfaces that are additively alignable one with another.
  • FIG. 1 is a partly diagrammatic longitudinal sectional view of a recorder head constructed in accordance with the invention, shown in quiescent or inactive state;
  • FIG. 2 is a view similar to that of FIG. I of the recorder head in an active state of printing
  • FIG. 3 is a cross-sectional view of FIG. 1 taken along the line IIIIII in the direction of the arrows.
  • FIG. 4 is, on an enlarged scale in longitudinalsection, the front end of printing rods 14 and 15 with the line types 20 and 21 in various positions;
  • b. shows in printing position, the printing rod 15 forimprinting the below represented code line of 0.1 mm width and mm length (length is illustrated in shortened form); c. shows in printing position, the printing rod 14 with the impression or imprint of a code line of 0.2 mm width; and d. shows in printing position, both printing rods 14 and 15 for making a code line of 0.3 mm. width.
  • FIG. 4A is shown a started line coding with the values 2 and 4 according to the code 1-2-4-2, whereby the beginning of the coding is illustrated by three lines and the coding end by a wide line.
  • a recorder head constructed according to the invention which includes a cylindrical housing 1, which can be provided with non-illustrated cooling ribs or vanes.
  • Three electrical pot-shaped magnets 2, 3 and 4, a ring-shaped plate 5, a forward end plate 6 and a rear guide plate 7 are securely mounted in the housing 1 by means of screws or bolts 8.
  • a casing 9 is located at the forward end plate 6, and a forward guide member 10 is secured by screws 11 therein.
  • An armature plate 12 is located between the pot-shaped magnet 2 and the ring-shaped plate 5, and a second armature plate 13 is located between the pot-shaped magnets 3 and 4.
  • the armature plates 12 and 13 are provided with anti-sticking or anti-adhesive sheets such as of phosphor-bronze, for example, which prevent adhesion thereof to the magnets 2, 3 and 4.
  • the pot-shaped magnets 2 to 4, the ring-shaped plate 5, the end plate 6, the guide plate 7 and the guide member 10 are formed with respective central bores through which two printing rods 14 and 15, respectively, having semicircular cross sections located opposite one another, as shown in FIG. 3, extend.
  • the printing rods 14 and 15 are provided with stepped portions 14a, 14b and 14c, on the one hand, and 15a to 15c, on the other hand, having cross sections of reduced semicircular dimensions, respectively, the end face of the stepped portion 15a serving as a stop for the armature plate 12 of the pot-shaped magnet 2, and the end face of the stepped portion 14b serving as stop for the annature plate 13 of the pot-shaped magnet 4.
  • the end stepped portions 140 and 150 of the respective printing rods 14 and 15 are respectively provided with a half shell 16 and 17 that extend as bearing shells in the central bore of the rear guide plate 7 and, in neutral or rest condition, extend through the bore of the restoring magnet 4 up to the armature plate 13 and form a stepped portion which serves as a stop of the armature plate 13 for the restoring magnet 4.
  • the printing rods 14 and 15 are provided with restoring springs 18 and 19, that are secured to a stationary frame represented by the pins 24, and are located at the free end 14c and 150 outside the housing 1.
  • a restoring magnet 4 is additionally provided.
  • the armature plate 13 engaged with the stepped portion 14b is displaced from ,the position thereof shown in FIG. 1 to the printing position thereof shown in FIG. -2. It is essential with respect thereto that the armature plate 13 comes into engagementwith the pot-shaped magnet 3 before the printing surface20a of the printing rod comes into contact with the record carrier 23 so that a free over-stroke of the printing rod 14 up to the contact is achieved.
  • the reversing or restoring magnet 4 is switched on and the armature plate 13 is displaced while engaged with the stop formed by the half shell 16 in direction opposite to the printing i.e., toward the top of FIG. 3.
