Abstract

A print wheel of the "daisy wheel' type includes a plurality of character support members, such as spokes 18, extending radially from a central hub (not shown) Each spoke 18 includes a base portion or pad 20 at the outer end thereof and a character element 22 extending upwardly from one surface 28 of the pad, Each character element has an impacting surface 24 of predetermined area defining the desired character configuration and one or more side walls 26 extending at a predetermined angle of incline from surface 28 of pad 20 to the im- pacting surface 24,

PRINT WHEEL (Cont'd)

Certain character elements, such as the capital letters "0"
and "U", have relatively large impacting surface areas
compared with that for a period, for example. Further, it
will be noted that the period occupies an area generally
central to its support pad 20. This is true with other
characters of small impacting surface area, such as the
decimal point, comma and hyphen. The subject disclosure
recognizes the desirability of decreasing the angle of
incline of the side wall or walls of character elements
having relatively small impacting surface areas, such as
the period, in order to increase its structural strength
and prolong its life.

The extent to which the angular incline of the side wal...
