Abstract: A desktop computer terminal having a keyboard in which an operator can enter data and an electronic display module for presenting data entered into and received by the terminal. The module casing is defined by a semi-cylindrical trough covered by a panel on which the display is mounted, the module being nested in a complementary cradle defined by a concavity in the housing of the terminal adjacent the planar face of the keyboard. The module is shiftable from a zero position in which its panel is coplanar with the face of the keyboard, at which position the module is fully nested in the cradle, to an angled position at which the panel is more or less inclined with respect to the keyboard face and the module is then partially nested in the cradle. Means are provided to maintain the display module at that angle which affords optimum visibility.
