Abstract

Abstract A main body case for storing a keyboard and an upper case for storing an integrated display/input device are coupled by hinge units to be arbitrarily pivotal from a state wherein the keyboard faces the integrated display/input device to a state wherein the back surfaces of the keyboard and the integrated display/input device face each other.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 203 words
A computer comprising: a main body unit having a keyboard; a display/input device having front and back surfaces, and including a display and a coordinate input tablet said display and said coordinate input tablet being overlapped, so as to form an integrated unit, and attached to the front surface of the display/input device; a support frame supporting said display/input device; a first hinge mechanism unit pivotally coupling said support frame to said main body unit, the first hinge mechanism for permitting the support frame to pivot between a closed position wherein said support frame and the display/input device overlay said keyboard, and an open position, wherein said support frame and the display/input device are angularly displaced from said keyboard; and a second hinge mechanism unit rotatably coupling said display/input device to said support frame, the input/display device being rotatable between a first position, wherein said front surface faces said keyboard when the support frame and the display/input device are in the closed position, and a second position, wherein said back surface faces said keyboard such that data can be input by means of said display/input device instead of said keyboard when the support frame and the display/input device are in the closed position.
Claim 2
Dependent Claim 203 words
A computer comprising: a main body unit having a keyboard; a display/input device having front and back surfaces, and including a display and a coordinate input tablet said display and said coordinate input tablet being overlapped, so as to form an integrated unit, and attached to the front surface of the display/input device; a support frame supporting said display/input device; a first hinge mechanism unit pivotally coupling said support frame to said main body unit, the first hinge mechanism for permitting the support frame to pivot between a closed position wherein said support frame and the display/input device overlay said keyboard, and an open position, wherein said support frame and the display/input device are angularly displaced from said keyboard; and a second hinge mechanism unit rotatably coupling said display/input device to said support frame, the input/display device being rotatable between a first position, wherein said front surface faces said keyboard when the support frame and the display/input device are in the closed position, and a second position, wherein said back surface faces said keyboard such that data can be input by means of said display/input device instead of said keyboard when the support frame and the display/input device are in the closed position.
Claim 3
Dependent Claim 31 words
A computer according to claim 1, wherein a rotational axis of said first hinge mechanism unit and a rotational axis of said second hinge mechanism unit are parallel with each other.
Claim 4
Dependent Claim 28 words
A computer according to claim 1, wherein a rotational axis of said second hinge mechanism unit is perpendicular to a rotational axis of said first hinge mechanism unit.
Claim 5
Dependent Claim 19 words
A computer according to claim 3, further comprising coordinate conversion means for vertically inverting an image on said display.
Claim 6
Dependent Claim 29 words
A computer according to claim 1, further comprising: a rotation lock mechanism for locking said display/input device at a predetermined rotational position with respect to the main body unit.
Claim 7
Dependent Claim 38 words
A computer according to claim 1, further comprising: a projecting portion for maintaining a gap between said keyboard and said display/input device when the support frame overlays the main body unit and the display/input device faces the keyboard.
Claim 8
Dependent Claim 24 words
A computer according to claim 1, wherein said first hinge mechanism unit is arranged on a rear end portion of said main body unit.
Claim 9
Dependent Claim 37 words
A computer according to claim 1, wherein said first hinge mechanism unit is arranged at a position offset from a rear end portion of said main body unit toward a central portion of said main body unit.
