Abstract

Disclosed is a device and method for synchronization of move- ment of a conductive web (injecting electrode) and an in- sulating web (blocking electrode) of a photoelectrophoretic recording device, The above illustration is representative of a means for achieving the stated objectives of this dis- closure,

Disclosed is a device and method for synchronization of move-
ment of a conductive web (injecting electrode) and an in-
sulating web (blocking electrode) of a photoelectrophoretic
recording device, The above illustration is representative
of a means for achieving the stated objectives of this dis-
closure,

In the above illustration, synchronization of movement of
a blocking electrode 8 and an injecting electrode 6 is
essential, (especially at the imaging zone), in order to
prevent smearing of an image which forms in response to
selective photoactivation of a pigment dispersion 10 which
is sandwiched between these two electrodes, This synchron-
ization of movement is achieved by providing conductive
roller 3 with conductive metal bands 4, 4 and differ-
entially biasing the roller and bands so as to achieve sub-
stantially greater fields across the webs in the areas

corresponding to bands 4 and 4'. The forces exerted by
stronger fields results in positive slip-free drive of both
webs by the conductive roller and thereby insures their
synchronous passage through the imaging zone.
