ABSTRACT:
BACKGROUND OF THE INVENTION
This application incorporates by reference Taiwanese application Serial No. 89214399, Filed Aug. 18, 2000.
1. Field of the Invention
The invention relates in general to a scanning apparatus which is able to power on automatically, and more particularly to a scanner which has an opening substantially above the start point of the carriage and protected by the glass plate.
2. Description of the Related Art
The integration and application of multi-media are now an overwhelming trend along with the advance and development of the technology. Multi-media include text, voice and image. Within all kinds of apparatus for capturing data, voice or image, image scanning apparatus is now a widely used one.
An auto-power on scanning apparatus is proposed by Mustek Systems Inc. in a R.O.C. patent no. 343029, which is illustrated in FIG.
1
. The conventional flatbed scanner as shown in
FIG.1
includes a main body
102
and a lid
104
. The scanning board
103
, which is the upper surface of the main body, supports the document to be scanned. The lid
104
is hinged to the board
103
by a hinge
106
so that the lid
104
can be shut and lifted freely. There is an opening
108
of the board
103
near the hinge
106
. A pattern
110
projects from the lid
104
matches the opening
108
.
FIG. 2
is the side cross-sectional view of the flatbed scanner as shown in
FIG. 1
, while the lid
104
is lifted. The scanner is equipped with a carriage
112
inside the main body
102
. The carriage
112
includes a light source
114
and a photo sensing module
116
, such as a charge-coupled device (CCD) or contact image sensor (CIS). The opening
108
is just above the photo sensing module
116
. While the lid
104
is lifted, the light emitted by the light source
114
reaches the lid
104
through the opening
108
but no reflected light from the pattern
100
through the opening
108
can be sensed by the photo sensing module
116
. The scanning program is then automatically started.
While the lid
104
is shut, as shown in
FIG. 3
, the light emitted from the light source
114
is transmitted through the opening
108
and reflected by the pattern
110
on the lid
104
. The light reflected from the pattern
110
then is transmitted through the opening
108
and is received by the photo sensing module
116
. The scanning program not started in this situation.
However, the auto-power on scanning apparatus has several disadvantages. First, dust may drop into the interior of the main body
102
of the scanner through the opening
108
. Second, the projected design of the pattern
110
is rather fragile and could easily be broken. Third, the projected pattern
110
needs a special package to protect itself, which obviously needs extra cost.
SUMMARY OF THE INVENTION
It is therefore an object of the invention to provide a scanning apparatus which is able to automatically power on but without the above-mentioned problems by forming an opening above the glass plate.
The invention achieves the above-identified objects by providing a scanning apparatus capable of automatically powering on. The scanning apparatus comprises a main body, a lid, a carriage inside the main body, and a scanner board. The lid is hinged to the main body. The scanner frame and extended under the scanner frame. The scanner board further includes an opening on the scanner frame. The opening exposes the glass plate thereunder and the opening is substantially above the start point of the carriage.
