The electronic device includes a case, an antenna element, a heat source, a heat dissipation member, a heat conduction member, a cooling fan, an exhaust port, and an exhaust duct. The case has a pair of main surfaces and side surfaces. The antenna element is used to perform wireless communication. The heat dissipation member exchanges heat with a cooling wind. The heat conduction member conducts heat of the heat source to the heat dissipation member. The cooling fan generates the cooling wind to be blown to the heat dissipation member. The exhaust port is an exhaust port from which the cooling wind is discharged to the outside. The exhaust duct guides the cooling wind to the exhaust port. The exhaust port is disposed on one of the side surfaces, and the antenna element and the exhaust duct are disposed to overlap each other at least partially in the thickness direction.

Electronic device

A heat conductor of electronic deviceincludes a heat conductive rubber having elasticity, a heat conductive plate having elasticity so as to be bending deformable, and heat conductive support members, which are disposed between a bottom face of a housing and a CPU in order in a direction from the CPU to the bottom face so as to abut the bottom face and the CPU. The heat conductive support members are configured to abut the heat conductive plate at a plurality of positions separated away from the heat conductive rubber in a surface direction. The heat conductive plate bending-deformed toward the bottom face is supported by the heat conductive rubber and the heat conductive support members.

A notebook computeris provided with: a casing in which a CPU is accommodated; a heat-dissipating componenthaving a plurality of fins; and a fan, and operates such that heat transferred from the CPU to the heat-dissipating componentis heat-exchanged with air supplied from the fan, and released to the exterior of the casing. The heat-dissipating componentis disposed at an air outletof the fan. An openingis formed, between the air outletand a fan main unit, in a fan case. First shutter meansis provided on a discharge outlet surface of the heat-dissipating component. With this structure, increase in cost and weight can be restrained, and dust on the heat-dissipating component can be removed with a simplified structure.

A notebook computer is provided with: a casing in which electronic components including a CPU are accommodated; and a heat-dissipating unit including a heat-dissipating componenthaving plural fins, and a fanfor supplying air to the heat-dissipating componentA communicating pathis formed between an air outletof the fanand a surfaceof the heat-dissipating componenton a side thereof that opposes the fanso as to communicate them. An openingis formed in a fan casebetween the air outletand a main unitof the fan. A ductis provided so as to communicate the openingwith the heat-dissipating componentWith this structure, an electronic device can be provided which has a built-in heat-dissipating unit that can restrain increase in cost and weight, and remove dust on the heat-dissipating component.

A communicating pathis formed, between an air outletof the fan, and an inflow surfaceof the heat-dissipating component, for communicating therebetween, and a dust removal pathis formed in the communicating pathso as to communicate with the exterior of the casing

An electronic device includes: a casing in which electronic components including a heat-emitting component which emits heat during operation are accommodated; a heat-dissipating component including a plurality of fins to which heat emitted in the heat-emitting component transfers; a fan operable to supply cooling air to the heat-dissipating component; and a cleaning component movable on an end surface of the fins along the side nearer the fan with the cleaning component abutting against the end surface of the fins. In these features, dust on the end surface of the fins can be automatically removed by moving the cleaning component in the case of the spatial orientation of the electronic device being changed. Therefore, an effect of removing heat emitted in the heat-emitting components, by using cooling air supplied from the fan, can be continuously obtained.

To provide a wireless communication system and a wireless communication method including: a first terminal apparatus comprising a computer main body and a second terminal apparatus comprising a displaying section, wherein the two terminal apparatuses perform wireless communication with each other without communication crossing. A management center obtains the positional information of a first terminal apparatus, and then records the positional information. The management center determines a communication channel free from communication crossing, depending on the positional information. The communication channel determined by the management center is transmitted to the first terminal apparatus. The first terminal apparatus and a second terminal apparatus perform wireless communication with each other through the received communication channel.

Wireless communication system

A word processor with a document retrieval function which successively and continuously displays retrieved documents which have been converted into code information and stored in the code information storage unit, so that by using a buffer memory of just little capacity, documents can be consecutively displayed at high speed, or at a specified high speed, or otherwise such consecutive display suspended and the documents generated one by one at high speed. In order to achieve this, the original code information is reduced so as to contain just enough information for retrieval purposes, and having been stored in the buffer memory, is used in the successive generation of the display image.
