Abstract: It is one object of the present invention to provide a portable information processing apparatus that can be employed with an overhead projector (OHP).A portable information processing apparatus according to the present invention comprises: a main body having a keyboard on an upper face; a lid having an internally mounted liquid crystal display panel and being hinged rotatably with the main body at the rear edge of the main body; and a tilting mechanism for positioning the front edge of the main body higher than its rear edge.

Abstract: An information processing apparatus in which arbitrary removal of a device for processing information accommodated within an opening within the main body can be prevented, regardless of operation of an eject button or the like, and to provide an information processing apparatus in which such prevention can be realized in a simple structure and at a low cost. A removal preventing latch is provided and inserted into an aperture within the main body of the information processing apparatus and through a corresponding aperture within the device for processing information. A cover for the main body may then be selectively locked in a closed position, preventing removal of the removal preventing latch while the cover is closed. A keyboard is preferably mounted to the cover for the main body.

Abstract: A docking device for a portable computer which can be utilized with a number of portable computers having diverse sizes is disclosed. The docking device includes a body having a number of electronic components disposed therein adapted to be electrically connected to a portable computer. A surface supported by the body is adapted to slidably receive a portable computer selected from among the number of portable computers having diverse sizes. Adjacent to the surface, at least two electrical connectors are disposed, including a first connector rotatably supported by the body which is rotatable between a first position and a second position. The selected portable computer may be electrically connected to the number of electrical components via only the first electrical connector when the first electrical connector is in the first position and may be electrically connected to the number of electronic components via only the second electrical connector when the first electrical connector is in the second position.

Abstract: An information processing apparatus is provided which includes a hard disk drive which is adapted to be accommodated within a main body of the information processing apparatus. The hard disk drive includes a movable member attached thereto. When the movable member slides into a first state, a portion of the movable member protrudes outside the main body of the information processing apparatus. A hinged keyboard is provided for covering the interior of the main body of the information processing apparatus and when the portion of the movable member protrudes outside the main body, the hinged keyboard is locked in a closed state. Additionally, a preventing latch is provided which may be utilized in conjunction with a card port in order to engage a PCMCIA card and prevent removal thereof. The preventing member is mounted under the keyboard such that when the keyboard is in a closed state, the PCMCIA card cannot be removed.
