Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable or portable device, such as a notebook or laptop personal computer or a word processor, which has a thin display portion and is not used. Sometimes, the display unit serves as a cover of the operation unit in the apparatus main body, so that the display unit and the operation unit can be seen and operated when the display unit is opened, and further, a display unit in which a heat radiation hole is formed in the apparatus main body. More specifically, the present invention relates to a technique for minimizing dust in the air from entering a device body through a heat radiation hole.

[0002]

2. Description of the Related Art In recent years, in information processing apparatuses such as personal computers and word processors, high-density mounting has progressed with the advancement of functions, and the size and weight of display units have been increased to improve visibility during work. As the thickness has been reduced, the density of various components in the apparatus main body has been remarkably increased. Also, for high-speed processing of image data with a large amount of information, MPU (Micro Processing Unit)
The speed and power consumption of electronic components such as semiconductors and semiconductor memories are increasing. Due to these synergistic factors, the degree of temperature rise inside the apparatus main body increases, and the operation of electronic components tends to be unstable.

Therefore, conventionally, a heat radiating hole is formed in the apparatus main body, and heat generated inside the apparatus main body when the information processing apparatus is operated is radiated to the outside through the heat radiating hole to thereby reduce the temperature inside the apparatus main body. We are devising to suppress the rise.
For example, in the device disclosed in Japanese Patent Application Laid-Open No. 6-318124, a heat sink is joined to an element generating a large amount of heat, and a heat radiating hole is formed near the heat sink in the apparatus body.

[0004]

The above-mentioned prior art has the following problems. During operation of the information processing device, heat in the device main body is released to the outside air through heat radiation holes formed in the device main body to suppress a rise in the temperature inside the device main body. The radiating holes communicate with the internal space of the apparatus main body and external air. The communication state between the inside and outside of the apparatus main body by the heat radiating hole is necessary when the apparatus is operating, but is not necessary when the apparatus is not operating. However, in the related art, there is little recognition that the heat radiating hole does not perform its function when it is not in operation, and it is considered that it is sufficient, and there is no particular problem.

[0005] However, the radiating holes which are always in communication with the inside and outside bring about the following disadvantages. When the heated air in the apparatus main body flows out through the heat radiating hole, dust in the external air rarely enters the device main body from the heat radiating hole due to the air flow. However, when there is no air flow, there is no airflow from inside to outside through the heat radiation holes, so that dust in the external air enters the apparatus main body. Nevertheless, the heat-dissipating holes in the internal / external communication state do not exhibit their original heat-dissipating function when not in operation. Conventionally,
It can be said that there was no recognition of such a problem.

An object of the present invention is to solve the above-mentioned problems and to prevent dust from entering the inside of the apparatus main body from outside air through a heat radiation hole in a non-use state.

[0007]

The cam portion 11 faces the passive curved surface 12a facing the slit 5c of the rear top plate portion 5. As shown in the figure, the shape of the cam portion 11 is such that when the display portion 3 is opened to its predetermined open position, the contact point with the passive curved surface 12a has the largest distance from the axis of the hinge mechanism portion 4 and the display portion 3 Is closed, the distance is gradually reduced, and the cam surface is such that the distance is minimized in a predetermined closing posture of the display unit 3. Hereinafter, the distance between the cam surface and the axis of the hinge mechanism 4 will be referred to as “cam radius”. Other configurations are described in Embodiment 1.
Since it is the same as (FIG. 8), the same reference numerals are given to the corresponding parts, and the description is omitted.

In the fourth embodiment, the slide type opening / closing means A described with reference to FIG. 2 is used as the radiating hole opening / closing means A, and the plate-shaped closing member 7 described with reference to FIG. The switching action transmitting means B employs the elastic biasing type described in FIG.

Although not shown, the operation of the display unit 3 in the closed position will be described. When the display unit 3 is in the closed position, the cam surface of the cam unit 11 has the smallest cam radius, and the urging force of the compression spring 51 is activated, and the compression spring 51 pushes the passive member 12 to all directions. The passive curved surface 12a of the passive member 12 is in contact with the cam portion 11 having the small cam radius. At this time, the opening hole 8 of the plate-shaped closing member 7 is out of phase with the radiating hole 6 of the rear top plate 5, and the radiating hole 6 is closed by the closing member 7.
That is, in the information processing apparatus in the non-use state,
Dust in the outside air is prevented from entering the inside of the apparatus main body 1. In addition, the open hole 8a of the bottom plate 5a remains open. Further, no heat radiation hole is formed in the back plate portion 5b. That is because the closing member 7 is plate-shaped.

As the display unit 3 is opened and rotated about the hinge mechanism 4 as a fulcrum, the cam unit 11 is rotated, and the radius of the cam is gradually increased. This pushes the passive member 12 backward. Along with this, the plate-shaped closing member 7 integrated with the passive member 12 slides rearward on the lower surface of the rear top plate portion 5 to open the display portion 3 to a predetermined open position as shown in FIG. At this time, the opening 8 of the closing member 7 has the same phase as the heat radiating hole 6 of the rear top plate 5, and the opening 8 communicates with the heat radiating hole 6. That is, the inside and outside of the apparatus main body 1 are communicated through the open holes and the heat radiation holes. During the operation of the information processing apparatus, the heat generated inside the apparatus main body 1 raises the temperature of the air inside the apparatus main body 1, and the heated air is discharged to the outside from the open holes / radiation holes in the communication state. You. External cool air is introduced from the heat radiation holes 6a of the bottom plate 5a. In this way,
Excessive temperature rise of the heating element 21 is prevented, and a thermally unstable operation is eliminated. The compression spring 51 is in a pressure accumulation state.

As the display unit 3 is closed and rotated about the hinge mechanism 4 as a fulcrum, the cam unit 11 is rotated so that the cam radius is gradually reduced, and the urging force of the compression spring 51 is activated. Then, the passive member 12 is pushed forward, and the closing member 7 is slid forward. When the display unit 3 is in a predetermined closing posture, the closing member 7 closes the heat radiation hole 6. Thereby, in the information processing apparatus in the non-use state, it is possible to prevent dust in the external air from entering the inside of the apparatus main body 1.

In the case of the fourth embodiment, the first embodiment
The same effect can be obtained, and the compression spring 51 has an appropriate resistance to the opening operation of the display unit 3, and there is no fear of an impact on the display unit 3 due to a sudden opening operation, and an appropriate operation is performed when the display unit 3 is closed. When there is a pressing force and the closing operation is completed, unexpected opening is prevented by the urging force of the compression spring 51. Therefore, the operation feeling is good. The structure is relatively simple.

Instead of providing the passive member 12 on the closing member 7, the closing member 7 itself may be extended to form a passive curved surface in contact with the cam portion 11 at the extended end.

[Fifth Embodiment] FIG. 12 is a sectional view showing the structure of the main part of a display opening / closing type information processing apparatus according to a fifth embodiment of the present invention in use.

At a predetermined open position of the display unit 3, the hook-shaped locking portion 68 abuts on the movable spring receiver 65, and pushes the movable spring receiver 65 forward while being guided by the spring receiving guide 63. Then, at the same time as the third compression spring 67 is contracted, the second compression spring 66 expands, and the force of the second compression spring 66 pushing the housing-like closing member 7 rearward decreases. Accordingly, the spring force of the first compression spring 61 is developed, and the housing-shaped closing member 7 is moved forward. As a result, the phase of the opening 8 of the closing member 7 coincides with that of the radiating hole 6 of the rear top plate portion 5, and the inside and outside of the apparatus main body 1 communicate with each other by the matching of the opening 8 and the radiating hole 6. Similarly, the heat radiating holes 6a of the bottom plate 5a and the heat radiating holes 6b of the back plate 5b are opened. In other words, the heat generated inside the apparatus main body 1 during the operation of the information processing apparatus raises the temperature of the air inside the apparatus main body 1, and the heated air flows from the open holes / radiation holes in the communicating state to the outside. Is discharged. This prevents excessive heating of the heating element 21 and eliminates a thermally unstable operation. Nevertheless, as described above, in an information processing apparatus that is not in use, dust in external air is prevented from entering the inside of the apparatus main body 1.
