Abstract

An integrated document handling and platen scanning apparatus is provided. The apparatus includes a main body; a platen glass positionally fixed to the main body; a CVT glass area positionally fixed to the main body; a first image module attached to the main body, the first image module being movable across the platen glass to scan an image on a first side of a document; a document handler attached to the main body and configured to invert the document and to feed the document across the CVT glass area; and an attachment point on the main body that attaches the main body to a copier body of a photocopier such that the main body, platen glass, first image module, and document handler move as a unit relative to the copier body. The first image module is configured to remain stationary and scan the image on the first side of the document as the document is fed across the CVT glass area.

First claim

What is claimed is:

1. An integrated document handling and platen scanning apparatus for detachable use with a photocopier, multifunctional printer or standalone scanning device; the apparatus comprising:
a main body;
a platen glass positionally fixed to the main body;
a CVT glass area positionally fixed to the main body;
a first image module attached to the main body, the first image module being movable across the platen glass to scan an image on a first side of a document when the document is stationary;
a document handler attached to the main body, the document handler being configured to invert the document and to feed the document across the CVT glass area; and
an attachment point on the main body that is adapted to detachably attach the main body to a device body of the photocopier, multifunction printer or standalone scanning device such that the main body, platen glass, first image module, and document handler are detachable as a unit from the device body and move as a unit relative to the device body,
wherein the first image module is configured to remain stationary and scan the image on the first side of the document when the document is fed across the CVT glass area.

2. The apparatus of claim 1 , further comprising a motor that drives the document handler to feed the document across the CVT glass area.

3. The apparatus of claim 2 , wherein the motor also drives the first image module to move it across the platen glass.

4. The apparatus of claim 1 , further comprising a second image module attached to the main body,
wherein the second image module is configured to scan an image on a second side of the document.

5. The apparatus of claim 4 , wherein the first image module and the second image module are configured to simultaneously scan the image on the first side of the document and the image on the second side of the document.

6. The apparatus of claim 5 , further comprising a motor that drives the document handler to feed the document across the first image module.

7. The apparatus of claim 6 , wherein the motor also drives the first image module to move it across the platen glass.

8. The apparatus of claim 4 , wherein the second image module is positionally fixed to the main body.

9. A copier, comprising:
a copier body;
an image forming section attached to the copier body;
a media supply attached to the copier body;
an output tray attached to the copier body and configured to receive media on which an image has been formed by the copier;
a surface on an upper area of the copier body;
an integrated detachable document handling and platen scanning apparatus having
a main body;
a platen glass positionally fixed to the main body;
a CVT glass area positionally fixed to the main body;
a first image module attached to the main body, the first image module being movable across the platen glass to scan an image on a first side of a document when the document is stationary;
a document handler attached to the main body, the document handler being configured to invert the document and to feed the document across the CVT glass area; and
an attachment point on the main body that attaches the main body to the copier body such that the main body, platen glass, CVT glass area, first image module, and document handler are detachable as a unit from the copier body and move as a unit relative to the copier body,

wherein the first image module is configured to remain stationary and scan the image on the first side of the document when the document is fed across the CVT glass area, and
the document handling and platen scanning apparatus is movably attached to the copier body such that the apparatus can be moved to a position in which the platen glass is adjacent and parallel to the surface on the upper area of the copier body.

10. The copier of claim 9 , wherein the document handling and platen scanning apparatus is attached to the copier body such that the platen glass is positionable parallel to the surface on the upper area of the copier body while at a plurality of different distances from the surface on the upper area of the copier body.

11. The copier of claim 9 , wherein the surface on the upper area of the copier body is a flat, opaque surface.

12. The copier of claim 11 , further comprising a light source located in the document handling and platen scanning apparatus,
wherein the platen glass is positioned between the light source and the surface on the upper area of the copier body.

13. The copier of claim 11 , further comprising a motor that drives the document handler to feed the document across the CVT glass area.

14. The copier of claim 13 , wherein the motor also drives the first image module to move it across the platen glass.

15. The copier of claim 9 , further comprising a second image module attached to the main body,
wherein the second image module is configured to scan an image on a second side of the document.

16. The copier of claim 15 , wherein the first image module and the second image module are configured to simultaneously scan the image on the first side of the document and the image on the second side of the document.

17. The copier of claim 16 , further comprising a motor that drives the document handler to feed the document across the CVT glass area.

18. The copier of claim 17 , wherein the motor also drives the first image module to move it across the platen glass.

19. The copier of claim 15 , wherein the second image module is positionally fixed to the main body.

20. The copier of claim 9 , further comprising a second image module positionally fixed to the main body; and
a light source located in the document handling and platen scanning apparatus,
wherein the second image module is configured to scan an image on a second side of the document,
the first image module and the second image module are configured to simultaneously scan the image on the first side of the document and the image on the second side of the document,
the document handling and platen scanning apparatus is attached to the copier body such that the platen glass is positionable parallel to the surface on the upper area of the copier body while at a plurality of different distances from the surface on the upper area of the copier body,
the surface on the upper area of the copier body is a flat, opaque surface, and
the platen glass is positioned between the light source and the surface on the upper area of the copier body.
