Abstract

A scanner includes a housing including a first slot, a platform installed on the housing for supporting a document, and an upper casing installed above the platform and rotatably connected to the housing. The upper casing includes a second slot. The scanner further includes a main hinge, connected between the housing and the upper casing. One end of the main hinge is fixed to the upper casing and the other end of the main hinge is positioned within the first slot. The upper case and the housing are connected via the main hinge. The scanner further includes a sub-hinge, connected between the housing and the upper casing, including a shaft and a body. The shaft is installed within the second slot, and the body is installed within the first slot in a slidable manner against the main hinge.

Claims

1. A scanner capable of pressing a document, the scanner comprising:

a housing comprising a first slot;

a platform, installed on the housing, for supporting a document;

an upper casing, installed above the platform and rotatably connected to the housing, the upper casing further comprising a second slot;

a main hinge, connected between the housing and the upper casing, wherein one end of the main hinge is fixed to the upper casing and another end is positioned within the first slot; and

a sub hinge, connected between the housing and the upper casing, comprising a shaft and a body, the shaft installed within the second slot and the body installed within the first slot in a slidable manner against the main hinge.

2. The scanner of claim 1 wherein the main hinge and the sub hinge are slidable against each other and the shaft of the sub hinge slides between a first position and a second position within the second slot.

3. The scanner of claim 2 wherein when the upper casing is rotating away from the platform, the shaft of the sub hinge moves towards the second position of the second slot, and the body of the sub hinge slides upwards along the main hinge.

4. The scanner of claim 2 wherein when the upper casing is rotating toward the platform, the shaft of the sub hinge moves towards the first position of the second slot, and the main body slides downwards along the main hinge.

5. The scanner of claim 4 wherein the document has a thickness, when the upper casing is sliding towards the platform, the main hinge moves in a vertical direction in the first slot corresponding to the thickness of the document.

6. The scanner of claim 1 wherein a depressed area is formed on the main hinge, a shape of the body of the sub hinge matching a shape of the depressed area.

7. The scanner of claim 6 wherein the first slot comprises a first width, and the main body of the sub hinge is wedge shaped, the main hinge and the sub hinge together form a second width when the depressed area of the main hinge receives the body of the sub hinge, and the second width is approximately greater than the first width.

8. The scanner of claim 7 wherein the main hinge is made of an elastic material.

9. The scanner of claim 7 wherein the sub hinge is made of an elastic material.

10. The scanner of claim 1 wherein the main hinge is uniform in width, the sub hinge is wider at the top and narrower at the bottom.

11. The scanner of claim 1 wherein the main hinge is narrower at the top and wider at the bottom, the sub hinge is wider at the top and narrower at the bottom.

12. The scanner of claim 1 wherein a width of the main hinge is narrower at the top and wider at the bottom, the sub hinge is uniform in width.

13. The scanner of claim 1 wherein the shaft of the sub hinge is detachable from the second slot of the upper casing.

14. The scanner of claim 1 wherein the main hinge comprises a fixed shaft to hinge with the upper case.
