Abstract

A ribbon lift guide is provided for use with a daisy wheel type print element for a serial printer. The ribbon lift guide comprises a generally circularly shaped flexible disc 70 coupled to the hub 8 of the composite print wheel 13 and is positioned on the side of the print wheel 13 containing the print surface of the character slug 2. Disc 70 lies in a plane parallel to a plane formed by the spokes 4. An annular or ring member 72 is coupled to the disc 70 and positioned between the disc 70 and spokes 4 of the print wheel l3- Ring 72 stabilizes the position of disc 70 during the rotation of print wheel 13 and during the printing operation. Ring 72, formed from foam plastic, also acts as a damper for spokes 4 after the printing operation with the particular character slug 2 attached to the spoke.

The space relationship between disc 70 and composite print
wheel 13 is shown more clearly in Figure 2. Disc 70 lies in a
plane parallel to a plane formed by spokes 4 and extends out-
ward from the hub 8 to a point near the closest point on the
print surface of the character slug 2. Disc 70 does not con-
tact character slugs 2. In the embodiment shown, disc 70 was
formed from the thermoplastic CELLULOID (trademark of Celane...
