Abstract

The self~containedCOPY numbering device 1 shown in Fig. 1 includes liquid crystal display digits 2 compactly mounted on unit 3 which contains batteries and counting chips. Light sensing element 4 is shown located on the surface of one of the liquid crystal display digits. Light sensing element 4 is operatively connected to the counting chips in unit 3 so as to index the numerical count shown by the display digits 2 upon each exposure to bright light.

FIG. 2

The self~containedCOPY numbering device 1 shown in Fig. 1
includes liquid crystal display digits 2 compactly mounted
on unit 3 which contains batteries and counting chips.
Light sensing element 4 is shown located on the surface of
one of the liquid crystal display digits. Light sensing
element 4 is operatively connected to the counting chips

display digits 2 upon each exposure to bright light.

2~s shown in Fig. 2, copy numbering device 1 is useful in a
copier adapted to make multiple copies of a single original.
Copy numbering device 1 is placed in any suitable location
on a copier platen 5 such as in the cutout area 6 of original
7,

COPY NUtv~ERINGDEVICE (Cont'd)

The numbering device is oriented so that the liquid crystal
display digits and the light sensing element face the
platen and become a part of the original.

When light source 8 moves in the direction shown by the
arrow
1 light is reflected from original 7, which includes
display digits 2 of numbering device 1, through lens
system 9 and then from mirror 10 to imaging surface 11 on
drum 12. Drum 12 moves in the direction shown by the arrow
synchronously with the movement of light source 8. The
bright light from light source 8 strikes ligh...
