Abstract

A device is provided for controlling skip movements of a form feed mechanism. This device operates to automatically position the form on the first printing line by sensing a mark on the form. It also terminates each skip by positioning the form on a selected line under instructions directed by control panel wiring.

Carriage Control For Printer

A device is provided for controlling skip movements of a form feed mechanism. This device operates to automatically position the form on the first printing line by sensing a mark on the form. It also terminates each skip by positioning the form on a selected line under instructions directed by control panel wiring.

A plurality of brushes 10 is mounted on a stationary ring 11 and may be selectively connected by a rod 12, sleeve 13 and plug wire 14. Each brush 10 represents a specific print line of a form.

A rotatable shaft 15 passing through the center of the ring 11 carries a toothed wheel 16 having teeth 17 and 17A on its opposite sides which cooperate with toothed dogs 18 and 18A to drive disks 19, 19A

Since each commutator is the mirror image of the other, is described. An electromagnet 20 having a cylindrical core 21 and a winding 22 is fixed concentrically on the shaft 15. An armature 23 is

Since each commutator is the mirror image of the other, only one is described. An electromagnet 20 having a cylindrical core 21 and a winding 22 is fixed concentrically on the shaft 15. An armature 23 is slidably mounted on the shaft 15 by a sleeve 24 which carries the disk 19 of insulating material on which the commutator segments 25, 26, 27, 28 are mounted. Axial extensions of the segments extend under commutator rings 30, 31, 32, 33 and are adapted to contact only one commutator ring at a time.

When an electromagnet 19 or 19A is energized,...
