Abstract

It is known to use a three track printing capability with a single strike printing ribbon 10 (see Figure 1). However, for a multi-strike ribbon, this capability does not take proper advantage of the characteristics of the ribbon 10 (see Figure 2).

It is known to use a three track printing capability with a single strike printing ribbon 10 (see Figure 1). However, for a multi~strike ribbon, this capability does not take proper advantage of the characteristics of the ribbon 10 (see Figure 2).

The subject mechanism consists of a spike ribbon driver capstan (not shown) geared to a drive system, consisting of a ratchet 12 and a "boxy' cam 14. When inserting a ribbon cartridge, a mechanism (not shown) is activated to detect the type of ribbon being used, i.e., single strike or multi-strike. The ratchet 12 may be fed by a solenoid or motor (not shown) and the box cam 14 has a follower 16. The developed cam path is depicted in Figures 4 and 5.
