RIBBON CARTRIDGE DRIVE APPARATUS (Cont'd)

A ribbon cartridge 60 can be connected to the carriage assem-
bly 44 of a serial printer (not shown) . A drive assembly for
advancing ribbon 62 through the cartridge 60 in response to

carriage movement includes a first portion located within the

cartridge housing 61 and a second portion to be described
below located exteriorily of the cartridge 60 and coupled to
the carriage. The first internal portion includes a capstan
roller 96 rotatably supported on a first pivot member 98
pivotably mounted by suitable means to a flange portion 94 at

a bearing member 92. The drive assembly also includes a
follower roller 102 supported on a second pivot member 104
pivotably mounted by suitable means about a pivot post 106
upstanding from the floor of the cartridge housing 61. A leaf
spring 108 is mounted between the pivot member 104 and the
adjacent side wall for biasing the follower roller 92 against
the capstan drive roller 96. The capstan drive roller commun-
icates with an opening (not shown) through the floor of the
housing in order for the second external portion of the drive
assembly to engage and drive the capstan roller 96. From the
nip between rollers 96 and 102, the ribbon 62 is advanced into
a main storage chamber 82 where it is randomly positioned as
shown.

Referring to Figure 2, the second external portion of the
drive assembly includes a drive drum 126 rotatably mounted by
suitable means to a flange portion 128 of a frame 130 of the
carriage assembly 44. A cable (not shown) may be wrapped

around the drum with one end connected to a first fastener
(not shown) mounted to the one side wall of the frame of a
printer, with the other end of such cable connected to a
second fastener (not shown) mounted to the opposite side wall

of the printer frame. The drum 126 will thus rotate in either
direction in response to linear movement of the printer car-
riage assembly...
