The present invention is directed to a computer in which an optional unit such as a unit including a wireless LAN adapter is installable. The computer including at least a computer body, a display, and a keyboard. The invention is also directed to a note book computer , which includes a computer body with a keyboard, and a display workable as a lid being opened and closed free with the computer body. In these computers with an optional unit , the optional unit is detachably attached to the top of the display, or the optional unit is detachably attached to a portion of the display, the portion being at a side of the display when the lid is closed and being at a top of the display when the lid is opened.

computer in which an optional unit is installable

To provide a portable computer in which a height and angle of a display can be adjusted even in a restricted installation space. In a notebook type personal computer, at an approximately middle portion in a high and low direction of an LCD unit, disposed in a lid, there is provided a hinge, which enables the LCD unit to pivot around a rotation axis crossing perpendicularly with the high and low direction of the LCD unit. This hinge is mounted so as to be movable in the high and low direction of the frame, and is disposed at a higher position than a top of the frame. Thereby, even when rear space where the notebook type PC is installed is restricted, it is possible to adjust the height and angle of the LCD unit, and to make such setting as to enable the display screen to be easily watched.

Portable computer

A radiation structure is employed in electronic apparatus such as a laptop computer having a body containing a heat generating element (e.g. CPU) and a display, rotatably connected to the body. The radiation structure transfers heat from the CPU to the outside of the apparatus and includes a first heatpipe; a hinge member connected to the host heatpipe for receiving heat therefrom; a second heatpipe for transferring heat from the hinge member to a radiation member placed in the display, one end of the second heatpipe being arranged substantially coaxially with the center of rotation of the display; and a sleeve member arranged in the hinge member coaxially with respect to the center of rotation of the display, the sleeve member being inserted from the outside into the inside of the display together with a portion of the second heatpipe which projects from the hinge member.

Radiation structure for electronic equipment and computer apparatus

A battery attaching mechanism for a portable computer by which an accommodated battery can be safely stored and secured, yet easily removed. The battery attaching mechanism comprises a recessed battery compartment provided on the body of the portable electronic apparatus, a latching member for latching the battery pack, said latching member being provided on a side wall of said battery compartment and having an outer latching member surface, a locking member for inhibiting said latching member from being released by contact with said outer latching member surface of said latching member, a connector for receiving a connector of said battery pack, and a removal assisting section for, in the vicinity of said connector, pushing said accommodated battery pack away from said connector.

Battery attaching mechanism for portable computers

An installation/removal structure for use with a generally rectangular peripheral device which may be temporarily installed within a portable data processing system. An engagement structure is provided within an interior portion of the portable data processing system and an electrical connector is mounted proximate to the engagement structure within the portable data processing system. An elongate flexible wire bail is swingably mounted across one end of the peripheral device, such that the elongate flexible wire bail can be engaged with the engagement structure by swinging the bail to a first position such that the peripheral device is held in electrical engagement with the electrical connector and when swung to a second position disengages from the engagement structure and may be utilized to remove the peripheral device from the portable data processing system.

Installation/removal structure for a device for an information

By the connection of a first subcard (26) to a main modem board (10), the modem system is customized to use an external data access arrangement (DAA) (32), while the connection of a second subcard (36) instead of the first customizes the modem system to use a built-in DAA (24). The subcards connect to the main modem board through a single interface connector (18). The first subcard includes a MiniDin connector (28) for connection to the external DAA, while the second subcard includes an RJ11 connector for direct connection to a telephone line. This mechanical arrangement results in a small, compact modem system suitable for use in a small computer.
