ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an apparatus, for cutting a photoreceptor web of an electrophotographic printer, which cuts a photoreceptor web installed in an electrophotographic printer.
2. Description of the Related Art
An electrophotographic printer such as a color laser printer, as shown in
FIG. 1
, includes a photoreceptor web
10
circulating along an endless path by being supported by a plurality of rollers
11
,
12
and
13
installed at a belt unit in the printer. An image to be printed is developed by a predetermined development unit
15
on one side of the photoreceptor web
10
. The developed image is dried while passing a drying unit
16
and printed on a sheet of paper
1
in a transfer unit
14
including a transfer roller
14
a
and a fixation roller
14
b.
The photoreceptor web
10
becomes worn over time, and eventually, the accuracy of a developed image deteriorates. Thus, the photoreceptor web
10
should be replaced after a certain amount of usage to maintain a clean developed image.
In a web replacing process, it is quicker and easier to cut a portion of the photoreceptor web
10
in the widthwise direction, as opposed to removing the photoreceptor web
10
(uncut) from the printer. In the “uncut” web removal process, the photoreceptor web
10
is pulled side by side from the rollers
11
,
12
, and
13
of the belt unit. However, in the “cut” web removal process, after the photoreceptor web
10
is cut, it may be easily pulled from the rollers
11
,
12
, and
13
, without prevention. Also, when the photoreceptor web
10
is cut and removed, a predetermined winding device may be used to wind the photoreceptor web
10
, and the use of various photoreceptor web disassembling devices is made possible. Therefore, a need exists for an apparatus for cutting a photoreceptor web installed in a printer in the widthwise direction.
SUMMARY OF THE INVENTION
It is an objective of the present invention to provide an apparatus for cutting a photoreceptor web of an electrophotographic printer, which can cut the photoreceptor web in the widthwise direction thereof when the photoreceptor web is to be removed from the printer.
To achieve the above objective, the photoreceptor web cutting apparatus includes a driving unit provided in the printer, and a cutting blade driven by the driving unit, for cutting the photoreceptor web while moving across the photoreceptor web in the widthwise direction thereof.
