Abstract

This proposal relates to a copy sheet registration adjustment mechanism for a reproducing machine, A timed relationship is maintained between the exposure system of the machine and the operation of a movable register gate in the paper path so that the copy sheet arrives at the image transfer station in proper registration with the image to be transferred to it. The timing is adjustable by means of belt 1 which is arranged about an optics drive pulley 2 and a register gate actuating cam pulley 3. The actuating cam is operative to move the register gate in and out of copy sheet blocking relationship, A pair of idler rolls 4 and 5 are supported on separate piv-oting plates 6 and 7 respectively, which are arranged to pivot about the optics drive shaft 8.

REGISTRATION AND TENSION ADJUSTING MECHANISM (Cont'd)

The tension of the belt 1 is adjusted by moving the idler rolls
4 and 5 closer together or further apart. After the tension
has been set, the plates 6 and 7 are locked together by means
of screw 9. The locked plates can still be pivoted about the
shaft 8, to provide a fine adjustment for the registration
gate timing. The rotation of the locked plates 6 and 7 effects
a small amount of rotation of the register ga...
