Abstract

The present invention discloses a pointing device having a computer host. The present invention comprises a cursor move device for moving the cursor and a command input device for inputting commands to the computer host. Among these, the computer host further includes a mother board, a CPU, a memory and at least one connecting port. Via the connecting ports, user interface such as a display and a keyboard can be connected to the present invention to form a complete computer.

Claims

1. A pointing device having a computer host, comprising:

a mother board;

a CPU (central processing unit), the CPU being coupled to the mother board;

a memory, being allocated on the mother board, the memory being electrically coupled to the CPU;

a cursor move device for moving a cursor, the cursor move device being electrically coupled to the CPU;

a command input device for inputting a command to the CPU, the command input device being electrically coupled to the CPU, and thereby the CPU responding to the command;

at least one connecting port, being allocated on the mother board, the connecting port being electrically coupled to the CPU;

a heat sink, the heat sink being on and adjacent to the CPU to dissipate heat generated by the CPU; and

a housing for encapsulating the mother board, the CPU, the memory and exposing a part of the connecting port, a part of the cursor move device and a part of the command input device, the housing comprises an upper case, the upper case at least has a plurality of air inlets substantially over the heat sink and the CPU and at least one exhaust outlet, via the air inlets, air being introduced to the CPU, via the exhaust outlet, the heat generated by the CPU is exhausted.
