Claims

[Claims for Utility Model Registration] 1. A laptop computer comprising a main computer main body and a display device rotatably attached to the main computer main body and electrically operated by the main computer body, the display device being a perforated display casing having a pair of window openings; a transparent liquid crystal monitor display mounted inside the display casing between the window openings; removable to the display casing at one of the window openings; a cover member which is mounted as shown in FIG. The display casing has a first hinge side plate removably attached to an adjacent second hinge side plate of the main computer body, and the display driving circuit means is connected to a first hinge side plate provided on the display casing. The main computer main body has a second electrical connector electrically connected to the first electrical connector. The display device further includes an extension cable for electrically connecting the first and second electrical connectors when removed from the computer body, so that the display device can be used as a slide for an overhead projector. a laptop computer, wherein the cover member is adapted to be removed from the display casing. 2. the first electrical connector is provided on the first hinge side plate, the second electrical connector is provided on the second hinge side plate, and the first electrical connector is configured to:
the display device engages the second electrical connector when the display device is secured to the main computer body; the main computer bodies are in series and interconnected on the second hinged side plate; further comprising: first, second and third cylindrical hinge portions spaced apart from each other; and a rotating pivot seat having a semicircular cross section provided between the first and second cylindrical hinge portions. the pivot seat rotatably engaging the first cylindrical hinge portion; the display casing extending from the first hinge side plate and proximate the first electrical connector; further comprising a curved wall having a quadrant cross section, the curved wall having one end adjacent the pivot seat, the curved wall also having:
when the display device engages the main computer body, the curved wall is also located between the first and second cylindrical hinge portions, and the curved wall is located between the first and second cylindrical hinge portions.
further removably and rotatably connected to a cylindrical hinge portion of the display casing; the display casing further having a perforated cylindrical lug disposed on the first hinge side plate; The computer further includes a cylindrical pivot pin having a portion inserted within the cylindrical lug and two ends removably engaging the second and third cylindrical hinge portions. the pivot pin remains in place with respect to the main computer body, and the cylindrical lug is rotatable with respect to the pivot pin when the display device is engaged with the main computer body.
