Abstract

A drawing device with a rotatable display screen is provided, having a housing having a cavity therein and a display screen sealingly rotatably coupled to the housing. An inner surface of the display screen forms an enclosure with the cavity. A powder is contained within the enclosure, the powder being removably adherent to the inner surface of the display screen. A first stylus controller is supported on an exterior of the housing. At least one positioning structure is supported in the enclosure and coupled to the first stylus controller to move a first stylus in a first set of directions that are parallel to a first axis. The first stylus removes the powder from the inner surface of the display screen through contact with the inner surface of the display screen.

First claim

The invention claimed is:

1. A drawing device, comprising:
a housing having a cavity therein;
a display screen sealingly rotatably coupled to the housing, an inner surface of which forms an enclosure with the cavity;
a powder contained within the enclosure, the powder being removably adherent to the inner surface of the display screen;
a first stylus controller supported on an exterior of the housing; and
at least one positioning structure supported in the enclosure coupled to the first stylus controller to move a first stylus in a first set of directions that are parallel to a first axis, the first stylus removing the powder from the inner surface of the display screen through contact with the inner surface of the display screen.

2. A drawing device as claimed in claim 1 , further comprising a second stylus controller supported on the exterior of the housing, wherein the at least one positioning structure is coupled to the second stylus controller to move the first stylus in a second set of directions that are parallel to a second axis.

3. A drawing device as claimed in claim 2 , wherein the second axis is orthogonal to the first axis.

4. A drawing device as claimed in claim 1 , wherein the at least one positioning structure additionally moves a second stylus in the first set of directions via the first stylus controller and in the second set of directions via the second stylus controller, the second stylus removing the powder from the inner surface of the display screen through contact with the inner surface of the display screen.

5. A drawing device as claimed in claim 1 , further comprising a display screen rotation controller supported on the exterior of the housing and controlling rotation of the display screen relative to the housing.

6. A drawing device as claimed in claim 5 , further comprising a rotation structure coupled to the display screen rotation controller and positioned within the cavity of the housing to reorient the display screen.

7. A drawing device as claimed in claim 1 , wherein the display screen can form part of a display screen assembly having a feature permitting manual rotation thereof.

8. A drawing device as claimed in claim 1 , wherein the inner surface of the display screen is planar.

9. A drawing device as claimed in claim 8 , wherein the first axis is parallel to the inner surface of the display screen.

10. A drawing device as claimed in claim 2 , wherein the inner surface of the display screen is planar, and the first and second axes are parallel to the inner surface of the display screen.

11. A drawing device as claimed in claim 1 , wherein one of an assembly of the display screen and the housing has a set of detents that are regularly angularly displaced and engaged by a biasable feature on another of the assembly of the display screen and the housing, the display screen being rotatable upon application of a threshold torque force thereon.

12. A drawing device as claimed in claim 1 , wherein the housing has a pan to which loose powder can fall that is positioned below a seal between the housing and the display screen.

13. A drawing device, comprising:
a housing having a cavity therein;
a display screen sealingly coupled to the housing, an inner surface of which forms an enclosure with the cavity;
a powder contained within the enclosure, the powder being removably adherent to the inner surface of the display screen;
a first stylus controller supported on an exterior of the housing; and
at least one positioning structure supported in the enclosure coupled to the first stylus controller to simultaneously move a first stylus and a second stylus in a first set of directions that are parallel to a first axis, the first stylus and the second stylus removing the powder from the inner surface of the display screen through contact with the inner surface of the display screen.

14. A drawing device as claimed in claim 13 , further comprising a second stylus controller supported on the exterior of the housing, wherein the at least one positioning structure is coupled to the second stylus controller to simultaneously move the first stylus and the second stylus in a second set of directions that are parallel to a second axis.

15. A drawing device as claimed in claim 14 , wherein the second axis is orthogonal to the first axis.

16. A drawing device as claimed in claim 13 , wherein the at least one positioning structure simultaneously moves the first stylus in a first of the first set of directions and the second stylus in a second stylus in a second of the first set of directions that is opposite the first of the first set of directions.

17. A drawing device as claimed in claim 16 , wherein the at least one positioning structure simultaneously moves the first stylus and the second stylus in a first of the second set of directions.

18. A drawing device as claimed in claim 13 , wherein the at least one positioning structure comprises:
a first set of pulleys;
a first endless cable routed around the first set of pulleys and having a delivery portion and a return portion;
wherein the first stylus is coupled to the delivery portion of the first endless cable; and
wherein the second stylus is coupled to the return portion of the first endless cable.

19. A drawing device as claimed in claim 18 , wherein the at least one positioning structure comprises:
a second set of pulleys; and
a second endless cable routed around the second set of pulleys and having a delivery portion and a return portion,
wherein the first stylus is coupled to the delivery portion of the second endless cable that is simultaneously moved with the delivery portion of the first endless cable in a first direction, and
wherein the second stylus is coupled to the return portion of the second endless cable that is simultaneously moved with the return portion of the first endless cable in a second direction opposite the first direction.

20. A drawing device as claimed in claim 19 , wherein the at least one positioning structure comprises:
a third set of pulleys;
a third endless cable routed around the third set of pulleys and having a delivery portion and a return portion;
a fourth set of pulleys; and
a fourth endless cable routed around the fourth set of pulleys and having a delivery portion and a return portion,
wherein the first stylus and the second stylus are coupled to the delivery portion of the third endless cable and the fourth endless cable that simultaneously move in a third direction.
