Abstract

An electrophotographic printing machine frequently employed a flexible photoconductive belt0 It is desirable to be capable of periodically replacing a used belt with a new belt. This may be achieved by advancing successive photoconductive belts stored on a spool 20 into an operative location, Figure 1(a) depicts the start of advancement of a photoconductive belt from spool 20 into an operative location entrained about rollers 12, 14 and 16. Initially, after the prior photocon-ductive belt has been removed from rollers 12, 14 arid 16, the next successive photoconductive belt 10 is advanced from spool 20. As shown in Figure 1(a), drive roller 24 is actuated to advance photoconductive belt 10 in the direction of arrow 52 so as to engage deflector 64.

flexible photoconductive belt

                       0 It is desirable to be capable
of periodically replacing a used belt with a new belt. This
may be achieved by advancing successive photoconductive belts
stored on a spool 20 into an operative location, Figure 1(a)
depicts the start of advancement of a photoconductive belt
from spool 20 into an operative location entrained about
rollers 12, 14 and 16. Initially, after the prior photocon~
ductive belt has been removed from rollers 12, 14 arid 16, the
next successive photoconductive belt 10 is advanced from spool
20. As shown in Figure 1(a), drive roller 24 is actuated to
advance photoconductive belt 10 in the direction of arrow 52
so as to engage deflector 64.

As shown in Figure 1(b), switch 66 determines the location of
tow bar 68 and actuates drive roller 24 to advance belt 10 to a
predetermined location. At this predetermined position, tow
bar 68 automatically engages the leading U-shaped portion of
belt 10. Tow bar 68 unwinds photoconductive belt 10 from
spool 20 advancing it in the direction of arrow 70. Hence,
belt 10 is entrained about rollers 12, 14 and 16.

As shown in Figure 1(c), after tow bar 68 advances belt 10
about rollers 14, 16 and 12, it once again engages switch 66.
Actuation of switch 66 by tow bar 68...
