There is disclosed a carriage control apparatus for a serial, impact computer printer. The carriage control apparatus comprises an encoder disk mounted for rotation on the carriage and having a coded pattern on its periphery, a photo sensor (and associated light source) for detecting the coded pattern and a drive means, preferably a serpentine toothed belt attached at each end to the printer's side frames that engages a sprocket wheel attached to the encoder disk to rotate the encoder disk in a fixed relationship to the carriage's position along the line of print of the printer.

Computer printer carriage control apparatus including an encoding disk

A device for mounting a paper tractor assembly between the side frames of a computer printer which allows the entire paper tractor assembly to be 'popped out' by the application of finger pressure alone, and which eliminates the cost of rounding the ends of the square drive rod of the paper tractor assembly. The mounting device consists of mounting brackets to secure the rods of the paper tractor assembly, bushings to engage the ends of the square drive rod and adapt them to fit into the mounting brackets, and springs or other resilient means to allow the paper tractor assembly to be 'popped out.'
