Positioning mechanism for a pen-based computing system
First Claim
1. A pen-based computing system comprising:
- a tablet unit including a display screen and an electronic assembly housed within an enclosure; and
a separate base unit including two panels connected via a hinge,a first one of the panels bearing a keyboard, anda second one of the panels being arcuately displaceable relative to the first panel to prop the tablet unit in a viewing position in which the display screen makes a viewing angle with the keyboard of greater than 90 degrees,wherein the tablet unit and the first panel have complementary formations to prevent sliding movement of the tablet unit relative to the first panel when in the viewing position,wherein the complementary formations include a male formation on the tablet unit shaped and dimensioned to mate with a complementary female formation on the first panel;
wherein the first panel includes a plurality of the female formations spaced along a longitudinal axis; and
wherein each female formation comprises two sliding members having ends contoured to form a recess to receive the male formation therein in a snug fit, wherein the sliding members are urged toward each other to close the recess.

6. A pen-based computing system comprising:
-
a base unit including a first and second panel connected by a flexible hinge; wherein the first panel has a generally flat body including a keyboard, and wherein the flexible hinge comprises a curved section extending into the second panel; a tablet unit comprising; a processing component including a processor coupled to a memory; a display component including a digitizer to capture data entered with the pen and a display screen coupled to the processing component; an enclosure defining a housing for the processing component and the display component, wherein the enclosure includes a mechanical stop to check sliding motion of the tablet unit relative to the first panel when the tablet unit is supported on the first panel so that it makes an acute angle therewith; wherein the second panel is in contact with the tablet unit in the said acute angle with the first panel; wherein the curved section of the hinge is coplanar with the bottom surface of the first panel; wherein a load from the tablet unit is directed through the second panel to the hinge, wherein the bend in the curved section of the hinge disperses some of the load acting on the hinge away from the first panel. - View Dependent Claims (7, 8, 9, 10, 11)

12. A pen-based computing system comprising:
-
a tablet unit comprising; a processing component and a display component including a digitizer to capture data entered with the pen and housed within an enclosure; a base unit comprising; a first and second panel connected by a flexible hinge; wherein the first panel has a generally flat body having a keyboard and at least one socket formation shaped and dimensioned to receive a spigot-like formation of the tablet unit, thereby to check sliding motion of the tablet unit relative to the first panel when the tablet unit is supported by the first panel so that it makes an acute angle therewith; wherein the flexible hinge comprises a curved portion extending into the second panel; wherein the second panel is in contact with the tablet unit in the said acute angle with the first panel; wherein the curved section of the hinge is coplanar with the bottom surface of the first panel; wherein, when in a viewing position, a load from the tablet unit is directed through the second panel to the hinge, wherein the bend in the curved section of the hinge disperses some of the load acting on the hinge away from the first panel. - View Dependent Claims (13, 14, 15)
