Abstract

Disclosed is a sliding panel structure of a multifunctional paper shredder, the paper shredder includes a housing having an interior space, an installing section at the top, an accommodating space at the bottom, and a feeding slot under the installing section. A pair of rolling blade wheels are disposed under the feeding slot which has a pressing wall surface extended vertically downward and aligned with the middle of the rolling blade wheels. An accommodating section is defined at the top of the housing, and a positioning section having at least one sliding groove is disposed at an inner side of the accommodating section. A sliding panel, having a plurality of slots is slidably installed in the accommodating section, having a positioning pin disposed in the positioning section correspondingly, and at least one slide pin embedded into the sliding groove for guiding the movement of the sliding panel.

Claims

1. A multifunctional paper shredder comprising:

a housing, enclosing an interior space and having a top panel at its top, and having an installing section disposed at an upper section of said interior space and an accommodating space disposed at a lower section of said interior space, and a feeding slot being defined on said top panel;

a pair of rolling blade wheels, being installed at said installing section and situated under said feeding slot and driven by a dynamic force;

at least one wall surface is extended vertically down from an inner side of said feeding slot of said top panel and aligned at the middle position of said pair of rolling blade wheels;

an accommodating section is disposed on an external surface of said top panel, and at least one positioning section is disposed at said upper section under said accommodating section and perpendicular to said feeding slot and at least one sliding groove is parallel to said positioning section;

a sliding panel comprising at least two inlets and slidably installed into said accommodating section, at least one positioning pin passing through said positioning section correspondingly, and at least one sliding pin being embedded into said sliding groove for guiding the movement of said sliding panel.

2. The multifunctional paper shredder of claim 1, wherein said accommodating section comprises a pair of sliding grooves separately disposed on both sides of said positioning section, and said sliding panel comprises a pair of sliding pins correspondingly embedded into said sliding grooves, and a hook section is defined at an outer side of an end of said sliding pin.

3. The multifunctional paper shredder of claim 2, wherein said sliding panel comprises a first inlet, a second inlet;

and a third inlet and said inlets are of unequal lengths, and said positioning section comprises a first aligner, a second aligner and a third aligner, and said first, second and third aligners are interconnected by a sliding groove.

4. The multifunctional paper shredder of claim 3, wherein said positioning pin has a C-shape cross section and a flexible property for sliding in said sliding groove.

5. The multifunctional paper shredder of claim 4, wherein said third inlet is aligned with said feeding slot when said positioning pin is situated at said third aligner.

6. The multifunctional paper shredder of claim 5, wherein said third inlet of said sliding panel has a length suitable for feeding a compact disc, and forms a guide section having a smaller width, a larger height and a smaller angle and is aligned with a wall surface perpendicular to said feeding slot.

7. The multifunctional paper shredder of claim 4, wherein said first inlet is aligned with said feeding slot when said positioning pin is situated at said first aligner.

8. The multifunctional paper shredder of claim 7, wherein said first inlet of said sliding panel has a length suitable for feeding a piece of paper, and forms a guide section having a larger width, a smaller height and a smoother angle.

9. The multifunctional paper shredder of claim 4, wherein said second inlet is aligned with said feeding slot when said positioning pin is situated at said second aligner.

10. The multifunctional paper shredder of claim 9, wherein said second inlet of said sliding panel has a length suitable for feeding a credit card, and forms a guide section having a smaller width, a larger height and a smaller angle and is aligned with a wall surface perpendicular to said feeding slot.

11. The multifunctional paper shredder of claim 1, wherein said accommodating section is in a semicircular shape, and said sliding panel forms a semicircle corresponding to said accommodating section.

12. The multifunctional paper shredder of claim 1, wherein said feeding slot comprises an infrared sensor disposed on an outer side of two walls of said feeding slot.

13. The multifunctional paper shredder of claim 1, wherein said sliding panel structure is installed on a lateral surface of said housing.
