Abstract

The device is an alphanumerical printer which is simple, reliable and inexpensive. Typewheel 1 receives two successive rotations by control wheel 2. These two rotations correspond respectively to the information in the in text and the out of text zones of a punched card. The first rotation, controlled by the in text zone, is due to the translation of rack 3. This translation is controlled by the action of sector 4. During each cycle, sector 4 rotates counterclockwise. Due to the action of spring 5, sector 4 is stopped by pawl 6 falling selectively in time according to the perforation read.

Alphanumerical Printing Device

The device is an alphanumerical printer which is simple, reliable and inexpensive. Typewheel 1 receives two successive rotations by control wheel 2. These two rotations correspond respectively to the information in the in text and the out of text zones of a punched card. The first rotation, controlled by the in text zone, is due to the translation of rack 3. This translation is controlled by the action of sector 4. During each cycle, sector 4 rotates counterclockwise. Due to the action of spring 5, sector 4 is stopped by pawl 6 falling selectively in time according to the perforation read.

The second rotation, controlled by the out of text zone, is due to translation of rack 7, of bar 8 and axle 9. Arm 10 pivots around fixed point 11. The translation of 7 is itself, on account of the action of spring 12, caused by the counterclockwise rotation, during each cycle, of sector 13. This translation is stopped selectively by pawl 14 according to the perforation read in the out of text zone of the card.

For the two successive controls of the pawl only one magnet 15 is necessary. This is because of the discrimination realized by the latching of pawl 14 by the continuously rotating cam 16 during the reading of the in text zone.
