Abstract

A scanning device includes an outer shell, a glass platform, a contact image sensor, a paper feeding unit and an upper cover. An inside of the outer shell has an accommodating space. The glass platform is disposed to the outer shell. The glass platform includes an automatic paper fed and scanned area, and a static paper scan area. The contact image sensor is disposed in the accommodating space. The paper feeding unit is disposed to a top surface of the automatic paper fed and scanned area. The upper cover is pivotally disposed to a top surface of the static paper scan area. A top surface of the upper cover is recessed downward to form a paper loading groove.

First claim

What is claimed is:

1. A scanning device, comprising:
an outer shell, an inside of the outer shell having an accommodating space;
a glass platform disposed to a top surface of the outer shell, the glass platform including an automatic paper fed and scanned area, and a static paper scan area;
a contact image sensor disposed in the accommodating space, and the contact image sensor being disposed under the glass platform, the contact image sensor including a sensor array, a driving motor connected with the sensor array, a driving gear connected with the driving motor, and a spline fastened to the outer shell, the driving gear being engaged with the driving motor, the sensor array being driven by the driving motor to move in the accommodating space;
a paper feeding unit disposed to a top surface of the automatic paper fed and scanned area for feeding a paper carrier through the automatic paper fed and scanned area; and
an upper cover pivotally disposed to a top surface of the static paper scan area, a top surface of the upper cover being recessed downward to form a paper loading groove,
wherein an axis direction of a pivoting shaft of the upper cover is perpendicular to a paper feeding direction of the paper feeding unit feeding the paper carrier, the paper loading groove is adjacent to a paper feeding side of the automatic paper fed and scanned area, so that the paper carrier which is to be scanned is guided by the paper loading groove to enter the paper feeding unit.

2. The scanning device as claimed in claim 1 , wherein the paper feeding unit includes a paper feeding shell, a paper feeding roller disposed inside the paper feeding shell, a guiding shrapnel and a paper feeding sensor, a transverse length of the paper feeding roller covers the whole automatic paper fed and scanned area, the paper feeding roller contacts with the glass platform for feeding the paper carrier, the guiding shrapnel has a flexibility in a direction perpendicular to a feeding path direction which is the paper feeding direction of the paper feeding unit, the guiding shrapnel includes a fastening end connected with the paper feeding shell, and a free end, the free end abuts against the paper feeding roller for guiding the paper carrier, the paper feeding sensor is disposed to a paper feeding side of the paper feeding roller for sensing the entered paper carrier, when the paper feeding sensor senses the paper carrier, the paper feeding roller is started.

3. The scanning device as claimed in claim 1 , wherein the paper feeding unit is pivotally disposed to the top surface of the automatic paper fed and scanned area for feeding the paper carrier through the automatic paper fed and scanned area.

4. The scanning device as claimed in claim 1 , further comprising a paper guiding unit mounted to the outer shell, the paper guiding unit being disposed to one side of the paper feeding unit to guide and feed out the scanned paper carrier, the paper guiding unit including a paper-out guiding block disposed to a paper-out side of the automatic paper fed and scanned area, the paper-out guiding block including an oblique surface facing the automatic paper fed and scanned area, and a guiding board pivotally disposed to the paper-out side of the automatic paper fed and scanned area.

5. The scanning device as claimed in claim 1 , wherein an inner surface of a front wall of the outer shell is flush with a front surface of the glass platform.

6. The scanning device as claimed in claim 1 , wherein a top of the outer shell away from the pivoting shaft of the upper cover is inclined frontward and downward to form an inclined surface.

7. A scanning device, comprising:
an outer shell, an inside of the outer shell having an accommodating space;
a glass platform disposed to a top surface of the outer shell, the glass platform including an automatic paper fed and scanned area, and a static paper scan area, an inner surface of a front wall of the outer shell being flush with a front surface of the glass platform;
a contact image sensor disposed in the accommodating space, and the contact image sensor being disposed under the glass platform;
a paper feeding unit disposed to a top surface of the automatic paper fed and scanned area;
a paper guiding unit mounted to the outer shell, the paper guiding unit being disposed to one side of the paper feeding unit to guide and feed out a scanned paper carrier, the paper guiding unit including a paper-out guiding block disposed to a paper-out side of the automatic paper fed and scanned area, the paper-out guiding block including an oblique surface facing the automatic paper fed and scanned area, and a guiding board pivotally disposed to the paper-out side of the automatic paper fed and scanned area; and
an upper cover pivotally disposed to a top surface of the static paper scan area, a top surface of the upper cover being recessed downward to form a paper loading groove, a rear end of a bottom surface of the upper cover protruding downward to form a pivoting shaft,
wherein an axis direction of the pivoting shaft of the upper cover is perpendicular to a paper feeding direction of the paper feeding unit feeding the paper carrier, the paper loading groove is adjacent to a paper feeding side of the automatic paper fed and scanned area, so that the paper carrier which is to be scanned is guided by the paper loading groove to enter the paper feeding unit.

8. A multifunction printer, comprising:
a scanning device including
an outer shell, an inside of the outer shell having an accommodating space,
a glass platform disposed to a top surface of the outer shell, the glass platform including an automatic paper fed and scanned area, and a static paper scan area,
a contact image sensor disposed in the accommodating space,
a paper feeding unit disposed to a top surface of the automatic paper fed and scanned area for feeding a paper carrier through the automatic paper fed and scanned area, and
an upper cover pivotally disposed to a top surface of the static paper scan area, a top surface of the upper cover being recessed downward to form a paper loading groove, a rear end of a bottom surface of the upper cover protruding downward to form a pivoting shaft, an axis direction of the pivoting shaft of the upper cover is perpendicular to a paper feeding direction of the paper feeding unit feeding the paper carrier, the paper loading groove is adjacent to a paper feeding side of the automatic paper fed and scanned area, so that the paper carrier which is to be scanned is guided by the paper loading groove to enter the paper feeding unit; and

a line printer unit mounted under the scanning device, including a paper box, a printing assembly, and a feeding assembly connected and disposed between the paper box and the printing assembly, the paper carrier to be printed being fed to the printing assembly from the paper box to be printed by the feeding assembly,
wherein the contact image sensor includes a sensor array, a driving motor connected with the sensor array, a driving gear connected with the driving motor, and a spline fastened to the outer shell, the driving gear is engaged with the driving motor, the sensor array is driven by the driving motor to move in the accommodating space.

9. The multifunction printer as claimed in claim 8 , wherein the paper feeding unit includes a paper feeding shell, a paper feeding roller disposed inside the paper feeding shell, a guiding shrapnel and a paper feeding sensor, a transverse length of the paper feeding roller covers the whole automatic paper fed and scanned area, the paper feeding roller contacts with the glass platform for feeding the paper carrier, the guiding shrapnel has a flexibility in a direction perpendicular to a fe
