Abstract

Claims (37)

1. An apparatus for cutting a workpiece, comprising:

a housing having an outer housing surface and an inner housing surface including at least a substantially planar first workpiece support surface, wherein the inner housing surface defines a cavity;

a cutting mechanism coupled to said housing and movably-arranged at least within said cavity;

a first door pivotally coupled to said housing, wherein the first door is pivotably-arranged relative to said housing in one of two positions including an open position and a closed position, wherein said first door includes an outer door surface and an inner door surface defining a substantially planar second workpiece support surface, wherein said outer door surface is substantially aligned with the outer housing surface when the first door is pivotably-arranged relative to said housing in the closed position, wherein said substantially planar second workpiece support surface of said inner door surface is arranged in a substantially co-planar orientation with said substantially planar first workpiece support surface when the first door is pivotably-arranged relative to said housing in the open position;

a biasing mechanism coupled to said first door for biasing said first door in said open position;

a second door pivotally coupled to said housing pivotable between an open position and a closed position;

a power button for turning on and off the power, said power button coupled to a release mechanism for releasing said second door from the closed position when said power button is depressed, said second door biased into an open position, said power button also coupled to a release mechanism for releasing said first door from the closed position when said power button is depressed; and

a user display coupled to an inside of said second door.

2. The apparatus for cutting a workpiece of claim 1 , wherein the first door provides

means for substantially enclosing the cutting mechanism within the cavity of the housing when the first door is pivotably-arranged relative to said housing in the closed position, and

means for exposing at least a portion of said cutting mechanism when the first door is pivotably-arranged relative to said housing in the open position, wherein one or more of the substantially planar first workpiece support surface and the substantially planar second workpiece support surface provides

means for supporting the workpiece that is to be cut by the cutting mechanism when the first door is pivotably-arranged relative to said housing in the open position.

3. The paper cutting apparatus of claim 1 , wherein said cutting mechanism comprises a drive roller for moving a sheet to be cut in a first direction and a cutting assembly positioned relative to said drive roller moveable in a second direction substantially perpendicular to said first direction, whereby combined controlled movement of said drive roller and said cutting assembly causes a shape to be cut in the sheet.

4. The apparatus for cutting a workpiece of claim 1 further comprising

a user interface coupled to said housing;

a processor coupled to one or more of user interface and the cutting mechanism, wherein the processor provides

means for receiving workpiece cutting instructions from the user by way of said user interface, wherein the workpiece cutting instructions control movement of said cutting mechanism; and

a memory device coupled to said processor, wherein said memory device provides means for permitting one or more of the functions of

selecting one or more previously-stored cutting instructions that are saved in the memory, and

storing one or more user-entered cutting instructions, wherein said memory device comprises

a removable cartridge.

5. The apparatus for cutting a workpiece of claim 4 , wherein the housing includes

a socket, wherein the socket provides

means for coupling said removable cartridge to said housing to allow communication of one or more of said previously-stored cutting instructions or said user-entered cutting instructions from said removable cartridge to said processor, wherein the inner door surface further defines

a cartridge recess integral with said inner door surface that accommodates the removable cartridge when the removable cartridge is coupled to the socket and when the door is pivotably-arranged relative to said housing in the closed position.

6. The apparatus for cutting a workpiece of claim 4 , wherein said user interface further comprises

a keyboard, wherein the keyboard includes a removable keyboard overlay, wherein said removable keyboard overlay includes a graphical representation of one or more of fonts, characters and images that correspond to available cutting instructions available for selection from the memory device.

7. The apparatus for cutting a workpiece of claim 4 , wherein said user interface provides

means for permitting a user to select a size of a shape to be cut into the workpiece.

8. The apparatus for cutting a workpiece of claim 7 , wherein said size of the shape to be cut into the workpiece includes at least three sizes.

9. The apparatus for cutting a workpiece of claim 4 , wherein said user interface comprises

at least one device, wherein the at least one device provides

means for allowing a user to select at least one of a speed and a pressure of the cutting mechanism, wherein the speed and the pressure of the cutting mechanism is selectable by the user in order to prevent tearing of the workpiece and to ensure that the cutting mechanism cuts through said workpiece.

10. The paper cutting apparatus of claim 1 , further comprising at least one handle incorporated into said housing for carrying said housing.

11. The paper cutting apparatus of claim 10 , wherein said at least one handle comprises at least one recess formed in said housing.

12. The paper cutting apparatus us of claim 10 , wherein said housing defines at least one recess for receiving at least a portion of said at least one handle therein, said at least one handle movable relative to said housing when grasped by a user to allow the user to carry said housing.

13. The paper cutting apparatus of claim 12 , wherein said at least one handle is pivotally coupled to said housing.
