Abstract
A hinge mechanism is disclosed which is suitable for use on a pivotable character display for an electronic typewriter or portable computer. The hinge mechanism includes braking means for maintaining the character display in a viewing position, wherein friction is generated between disc shaped brake members of the hinge mechanism. Moreover, the addition of a cam in the hinge mechanism provides the selective use of torque to the braking means; the cam is engaged when the display is in a viewing position, preventing the display from slipping out of position, whereas the cam is not engaged when the display is near the horizontal, making it easier to raise and to lower the display. The hinge mechanism disclosed is suitable for use with multi-view position character displays as well as with single view position character displays.
