Scanning apparatus

Abstract

A scanning apparatus includes a body, a transparent plate, a scanning module, and a color reference slice. A paper-feeding track is formed within the body, and a scanning window is formed at a side wall of the paper-feeding track. A coupling groove is formed at an edge of the scanning window. Both the transparent plate and the color reference slice have an edge being inserted into the coupling groove, such that the transparent plate covers the scanning window while the color reference slice leans against a side surface of the transparent plate facing the paper-feeding track. The scanning module is disposed within the body corresponding to the scanning window, such that a paper to be scanned and the color reference slice are located in the same plane, and the color reference slice and the paper are scanned under the same optical conditions.

Claims

1. A scanning apparatus, comprising: a body, having a paper-feeding track formed within the body and a scanning window formed at a side wall of the paper-feeding track, wherein a coupling groove is formed at an edge of the scanning window, and a supporting portion is correspondingly formed at the opposite edge thereof;a transparent plate disposed at the scanning window, wherein an edge of the transparent plate is inserted into the coupling groove and the other edge of the transparent plate leans against the supporting portion;a scanning module disposed within the body corresponding to the scanning window, wherein the transparent plate is located between the scanning module and the paper-feeding track; anda color reference slice with an edge being inserted into the coupling groove, wherein the color reference slice leans against one side surface of the transparent plate facing the paper-feeding track.

2. The scanning apparatus as claimed in claim 1, wherein the body includes a base and a cover, and a spacing distance exists there-between to form the paper-feeding track.

3. The scanning apparatus as claimed in claim 2, wherein the scanning window is formed on the base.

4. The scanning apparatus as claimed in claim 1, wherein the supporting portion is stair-shaped.

5. A base of a scanning apparatus, wherein a scanning module is disposed within the base, comprising: a scanning window, formed on the base corresponding to the scanning module;a transparent plate, disposed at the scanning window and covering the scanning window; anda color reference slice, disposed at a side surface of the transparent plate away from the scanning module.

6. The base of a scanning apparatus as claimed in claim 5, wherein a coupling groove is formed at an edge of the scanning window, and an edge of the transparent plate and an edge of the color reference slice are both inserted into the coupling groove.

7. The base of a scanning apparatus as claimed in claim 6, wherein a supporting portion is formed at the other edge of the scanning window opposite to the coupling groove, and the other edge of the transparent plate leans against the supporting portion.

8. The base of a scanning apparatus as claimed in claim 6, wherein the supporting portion is stair-shaped.
