Abstract

A band-dot printer has a flexible ballistic band in which the ballistic mass controls the print energy while keeping all the parameters of the print hammer fixed. A dot band printer (Fig. 1) has a flexible band 2 that is suspended on a drive 3 and idler pulley 4 and is driven horizontally in front of print actuators 5. The print actuators act on ballistic buttons 6 that contain dot-producing elements and are flexurally hinged on segments within the band. The buttons are fastened to the hinged segments by welding or other suitable means and are propelled by the actuator and continue in motion with their attached dot element 11 (Figs. 2 and 3) even after the actuators forward motion is arrested by a stop.

Ballistic Band-Dot Printer Accepting Print Bands With Different Buttons Serving As Ballistic Print Elements

A band-dot printer has a flexible ballistic band in which the ballistic mass controls the print energy while keeping all the parameters of the print hammer fixed. A dot band printer (Fig. 1) has a flexible band 2 that is suspended on a drive 3 and idler pulley 4 and is driven horizontally in front of print actuators 5. The print actuators act on ballistic buttons 6 that contain dot-producing elements and are flexurally hinged on segments within the band. The buttons are fastened to the hinged segments by welding or other suitable means and are propelled by the actuator and continue in motion with their attached dot element 11 (Figs. 2 and 3) even after the actuators forward motion is arrested by a stop. The buttons have a predetermined mass and are propelled at a velocity so as to possess adequate kinetic energy to enable them to cause printing when the dot element strikes ribbon 9 and paper 8 which is backed by a platen 10. It is therefore possible to have various mass button and dot element combinations to impart more or less energy for respective large or small size dot elements. Large dot elements 11 (Fig. 2) would have greater mass buttons, and small dot elements 11 (Fig. 3) would have smaller mass buttons. Therefore, the same actuator can be used to produce printed dots having a wide range of dot diameters while supplying the proper energy for each do...
