ABSTRACT:

BACKGROUND OF THE INVENTION
(1) Field of the Invention
This invention relates to a scanner, particularly to the cover of a scanner, copier, facsimile, etc.
(2) Brief Description of the Related Art
FIG. 1
shows a prior art scanner. The main body has a frame
10
and a scan window
12
, on which a piece of paper P is placed. The scanner includes a cover having a lid
11
which is closed during scanning. The soft plate
15
, which is slightly smaller than the scan window
12
, is attached under the lid
11
through a block
13
made of foam rubber or sponge and presses against the piece of paper P, so that the paper lies flat against the scan window
12
.
The soft plate
15
and the block
13
, to which the soft plate
15
is attached, occupy vertical space and increase the cost of the cover. When the cover is lifted, the cover tends to suck the paper and to fly the paper.
SUMMARY OF THE INVENTION
An object of this invention is to reduce the overall thickness of the cover. Another object of this invention is to reduce the cost of the cover. Still another object of this invention is to avoid the scan paper from flying when the cover is lifted.
These objects are achieved by replacing the soft plate with an elastic convex bottom plate. An air duct is provided between the cover and the elastic plate, so that the paper does not fly when the cover is lifted.
