[First Embodiment] FIG. 4 is a cross-sectional view showing a configuration of a main part in a use state of a display section opening / closing type information processing apparatus such as a notebook personal computer according to a first embodiment, and FIG. It is sectional drawing in a state.

The apparatus body 1 includes a CPU (Central Processing Unit), a ROM (Read Only Memory),
A circuit board 21 on which an AM (random access memory) and various electronic parts and electric parts are mounted, a floppy disk driver and a CD-ROM driver (not shown) are incorporated in the casing 7. The figure shows a state in which one heating element 6 is mounted on a circuit board 21. A typical example of the heating element 6 is a CPU. An operation unit 2 such as a keyboard and a trackball is provided on an upper surface of the apparatus main body 1. Legs 22 are provided on the bottom surface of the apparatus main body 1. A thin display section 3 such as a liquid crystal display (LCD) is pivotally attached to the apparatus main body section 1 via a hinge mechanism section 4 behind the operation section 2 so as to be freely opened and closed. By closing the display unit 3 when the information processing device is not used, the operation unit 2 is covered, thereby preventing dust from adhering to the operation unit 2 and preventing the display unit 3 from being damaged. By opening the display unit 3 during use,
The display unit 3 becomes visible and the operation unit 2 becomes operable.

A heat sink 5 is provided inside the apparatus main body 1 so as to slide along the upper surface of the heating element 6. Guide grooves 5b are formed on both side surfaces of the heat sink 5 along the horizontal direction, and guide pins 23 provided on the circuit board 21 are engaged with the respective guide grooves 5b. A plurality of radiation fins 5a are provided integrally on the rear surface of the heat sink 5. A radiation fin 5a is provided on a casing 7 of the apparatus main body 1.
A through hole 7a is formed to move the head. An apparatus main body 1 is provided on an upper surface and a lower surface of a rear portion of the casing 7.
Exhaust holes 7b and 7c for discharging the heated air inside are formed.

The hinge mechanism 4 and the front end of the heat sink 5 are linked to each other via a link 24. Link 2
One end of the link 4 is pivotally supported by the hinge mechanism 4 via a pin 25, and the long hole 24 a of the other end of the link 24 is pivotally supported by the heat sink 5 via a pin 26. A slit 7d for inserting the link 24 is formed in the casing 7.

FIG. 5 shows a state in which the display unit 3 is closed and the operation unit 2 is covered. At this time, the entire heat sink 5 is housed inside the casing 7 of the apparatus main body 1, and the radiation fins 5a of the heat sink 5 are immersed inside the through holes 7a. The pin 25 for pivotally supporting the link 24 to the hinge mechanism 4 is at the most front position.

As the display unit 3 serving as the lid is opened and rotated about the hinge mechanism 4 as a fulcrum, the pin 25 also draws an arc locus about the axis of the hinge mechanism 4 as a center of rotation, and then moves upward once. Move, then move backward. Accordingly, a force directed rearward and downward is applied to the heat sink 5 via the link 24. The lower surface of the heat sink 5 is slidably mounted on the upper surface of the heating element 6, and has a horizontal guide groove 5.
b is engaged with the guide pin 23, only the horizontal component force acts on the heat sink 5, and the heat sink 5
Will slide outward. As shown in FIG. 4, when the display unit 3 is opened to a predetermined open posture, the link 2
As the heat sink 5 slides outward through the heat sink 4, the heat radiation fins 5a of the heat sink 5 protrude outside through the through holes 7a, and the heat radiation fins 5a come into direct contact with the outside air.

During the operation of the information processing apparatus, the heat generated from the heating element 6 and various parts other than the heating element 6 raises the temperature of the air inside the casing 7, and the heated air is discharged from the exhaust holes 7b and 7c to the outside. Is discharged to The heat generated by the heating element 6 generating a large amount of heat is taken by the heat sink 5. Although the temperature of the heat sink 5 rises, a plurality of radiating fins 5a at the rear of the heat sink 5 project outside from the through hole 7a of the casing 7 and come into direct contact with the outside air. In comparison, the heat radiation effect is high, and the heat sink 5 is efficiently cooled. Therefore, the function of the heat sink 5 to remove heat from the heat generating element 6 is sufficiently exhibited, and the function of suppressing the temperature rise is high. That is, excessive heating of the heating element 6 can be prevented, and thermally unstable operation can be reliably eliminated.

The pin 25 of the link 24 moves forward with the rotation of the display unit 3 about the hinge mechanism 4 as a fulcrum, so that the heat sink 5 slides inward via the link 24. When the display unit 3 is in the closed position as shown in FIG. 5, the radiation fins 5a enter the casing 7 through the through holes 7a. As described above, when the display unit 3 serving as the lid is closed and not in use, the radiation fins 5a are immersed through the through holes 7a, so that the appearance does not need to be poor. Also, when the information processing device is moved or carried, the radiation fins may hit other objects and receive mechanical shocks, damaging various internal electronic and electrical components.
Since the radiation fins 5a are immersed when not in use, such a problem can be avoided.

As described above, in the case of the first embodiment,
The link 24 forms the interlocking connection mechanism 8 described with reference to FIG. The structure of the interlocking connection mechanism 8 is extremely simple, the number of parts can be reduced, and the cost can be suppressed.

[Second Embodiment] FIG. 6 is a sectional view showing the structure of a main part of a display opening / closing type information processing apparatus according to a second embodiment of the present invention in use. In the second embodiment, the interlocking connection mechanism 8 described in FIG. 1 is configured by a combination of a pinion gear mechanism 31 and a rack mechanism 32. The other configuration is the same as that of the first embodiment (FIGS. 4 and 5), and therefore, the same reference numerals are given to the corresponding parts, and description thereof is omitted.

The structure of the second embodiment will be described. A gear 31a is mounted on the hinge mechanism 4 of the display unit 3 so that the center thereof is aligned with the axis thereof.
A pinion gear 31b that meshes with a is rotatably supported at an appropriate position in the apparatus main body 1. On the other hand, a rack mechanism 32 is mounted on the upper surface of the heat sink 5, and a pinion gear 31b is meshed with the rack mechanism 32.

When the display unit 3 serving as the lid is opened and rotated about the hinge mechanism 4 as a fulcrum, the gear 31a rotates clockwise and the pinion gear 31b rotates counterclockwise. The gear 31b pushes the rack mechanism 32 backward, and the heat sink 5 slides backward on the upper surface of the heating element 6 with the horizontal guide groove 5b guided by the guide pin 23, and the solid line in FIG. As shown in
When the display unit 3 is opened to a predetermined open position, the heat radiation fins 5a of the heat sink 5 project outside from the through holes 7a, and the heat radiation fins 5a come into direct contact with the outside air.

As the display unit 3 is closed and rotated about the hinge mechanism 4 as a fulcrum, the gear 31a is rotated counterclockwise and the pinion gear 31b is rotated clockwise, so that the pinion gear 31b is rotated. When the rack mechanism 32 is pushed forward, the heat sink 5 is slid forward and the display unit 3 is in the closed position, as shown by the two-dot chain line in FIG. It sinks into the inside of the casing 7.

In the case of the second embodiment of the present invention, the same effect as that of the first embodiment can be obtained, and the interlocking connection mechanism 8 is a combination of the pinion gear mechanism 31 and the rack mechanism 32. Very simple,
Also, the interlocking operation is smooth.

[Third Embodiment] FIG. 7 is a sectional view showing the structure of a main part of a display opening / closing type information processing apparatus according to a third embodiment of the present invention in use. Embodiment 3 corresponds to the one provided with the urging mechanism 9 and the cam portion 10 described in FIG. Other configurations are the same as those of the first embodiment (FIG. 4), and therefore, the same reference numerals are given to the corresponding portions, and description thereof is omitted.

The configuration of the third embodiment will be described. A passive member 41 is integrally connected to the upper surface of the heat sink 5 by an appropriate means such as an adhesive or a screw. The front end surface of the passive member 41 is a smooth passive curved surface 41a. The rear end face of the passive member 41 is vertical, and the rear end face and the casing 7
A compression spring 42 as an urging mechanism 9 for urging the heat sink 5 inward is interposed between the inner wall surface and the inner wall surface. The hinge mechanism 4 is provided with a cam portion 10 that abuts the passive curved surface 41a of the passive member 41. As shown in the figure, the shape of the cam portion 10 is such that the distance from the axis of the hinge mechanism portion 4 is the largest when the display portion 3 is opened to its predetermined open position, and the distance gradually decreases as the display portion 3 is closed. That is, the cam surface is such that the distance becomes minimum in a predetermined closed 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”.

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 posture, the cam surface of the cam unit 10 has the smallest cam radius, the urging force of the compression spring 42 is activated, and the compression spring 42 pushes the passive member 41 inward. The passive curved surface 41a of the passive member 41 is in contact with the portion of the cam portion 10 having the small cam radius. Therefore, the heat sink 5 moves inward along the upper surface of the heating element 6 in a state where the horizontal guide groove 5b is guided by the guide pin 23, and the radiation fins 5a of the heat sink 5 are connected to the through holes 7a of the casing 7. It is in a state immersed further inside.

As the display unit 3 is opened and rotated about the hinge mechanism 4 as a fulcrum, the cam unit 10 is rotated, and the cam radius is gradually increased. As a result, the passive member 41 is pushed backward. Along with this, the heat sink 5 integrated with the passive member 41 slides backward on the upper surface of the heating element 6 in a state where the guide groove 5b in the horizontal direction is guided by the guide pin 23, and as shown in FIG.
When the display unit 3 is opened to a predetermined open position, the heat radiation fins 5a of the heat sink 5 project outside from the through holes 7a, and the heat radiation fins 5a come into direct contact with the outside air.
The compression spring 42 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 10 is rotated so that the cam radius is gradually reduced, and the urging force of the compression spring 42 is activated. As a result, the passive member 41 is pushed forward, the heat sink 5 is slid forward, and the radiation fins 5a enter the casing 7 through the through holes 7a when the display unit 3 is in a predetermined closed position.

In the case of the third embodiment, the first embodiment is used.
And the compression spring 42 has an appropriate resistance to the opening operation of the display unit 3, so that there is no danger 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 is completed, accidental opening is prevented by the urging force of the compression spring 42. Therefore, the operation feeling is good. The structure is relatively simple.

[Fourth Embodiment] FIG. 8 is a cross-sectional view showing the structure of a main part of a display-opening / closing type information processing apparatus according to a fourth embodiment of the present invention in use. The fourth embodiment is a modification of the third embodiment described with reference to FIG. 7, in which a damper mechanism 53 is added. The other configuration is the same as that of the third embodiment (FIG. 7), and therefore, the same reference numerals are given to the corresponding parts, and the description is omitted.

The configuration of the fourth embodiment will be described. A passive member 51 is integrally connected to the upper surface of the heat sink 5 by an appropriate means such as an adhesive or a screw. A compression spring 52 as an urging mechanism 9 for urging the heat sink 5 inward is interposed between the rear end surface of the passive member 51 and the inner wall surface of the casing 7. The hinge mechanism 4 is provided with a cam 10 similar to that of the third embodiment. A damper mechanism 53 is interposed between the cam portion 10 and the passive member 51. The damper mechanism 53 includes an arm 55 fixed to the passive member 51 with a screw 54, a telescopic rod 56 attached to the arm 55, a compression coil spring 57 fitted around the telescopic rod 56, and the other end of the telescopic rod 56. And a plunger 58 having a passive curved surface 58a abutting on the cam surface of the cam portion 10.

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 posture, the cam surface of the cam unit 10 has the smallest cam radius, the urging force of the compression spring 52 is activated, and the compression spring 52 pushes the passive member 51 inward. The passive curved surface 58a of the plunger 58 is in contact with the cam portion 10 having the small cam radius. Therefore, the heat sink 5 has its horizontal guide groove 5b provided with the guide pin 23.
The heat sink 5 is moved inward along the upper surface of the heat generating element 6, and the heat radiation fins 5 a of the heat sink 5 are immersed inside the through holes 7 a of the casing 7.

As the display unit 3 is opened and pivoted with the hinge mechanism 4 as a fulcrum, the cam unit 10 pivots, and the cam radius gradually increases, and the cam unit 10 resists the urging force of the compression spring 52. As a result, the passive member 51 is pushed backward via the damper mechanism 53. Along with this, the heat sink 5 integrated with the passive member 51 slides rearward on the upper surface of the heating element 6 with the horizontal guide groove 5b guided by the guide pin 23, as shown in FIG. When the display unit 3 is opened to a predetermined open position, the heat radiation fins 5a of the heat sink 5 project outside from the through holes 7a, and the heat radiation fins 5a come into direct contact with the outside air. The compression spring 52 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 10 is rotated so that the cam radius is gradually reduced, and the urging force of the compression spring 52 is activated. As a result, the passive member 51 is pushed forward, the heat sink 5 is slid forward, and when the display unit 3 is brought into a predetermined closed posture, the radiation fins 5a enter the casing 7 through the through holes 7a.

In the case of the fourth embodiment, the first embodiment
The same effect as described above can be obtained, and even when the cam portion 10 and the heat sink 5 are separated from each other, the pressing force of the cam portion 10 can be reliably and smoothly transmitted to the heat sink 5 via the damper mechanism 53. In addition, the sliding of the heat sink 5 can be performed stably and smoothly.

In the third and fourth embodiments, the urging mechanism 9 is constituted by the compression springs 42 and 52 so as to apply a pressing urging force to the heat sink 5. Biasing mechanism 9 with tension spring
May be configured.

[Fifth Embodiment] FIG. 9 is a cross-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. In the fifth embodiment, the outward urging mechanism 11 and the inner urging mechanism 12 described in FIG.
It has something. Other configurations are described in Embodiment 1.
Since this is the same as (FIG. 4), the corresponding parts are denoted by the same reference numerals, and description thereof is omitted.

The configuration of the fifth embodiment will be described. A passive member 61 is integrally connected to the upper surface of the heat sink 5 by an appropriate means such as an adhesive or a screw. A bracket 62 is attached to the inner wall of the casing 7, and a first rubber cord 63 is stretched between the bracket 62 and the rear end of the passive member 61. The first rubber cord body 63 constitutes an outward urging mechanism 11 that applies an outward urging force to the heat sink 5. A second rubber cord 64 is stretched between the hinge mechanism 4 of the display unit 3 and the front end of the passive member 61. The second rubber cord body 64 is wound around two pulleys 65 and 66 so as to wrap the heat sink 5 in an “U” shape so as to apply an inward biasing force to the heat sink 5. Second
Constitutes an inward biasing mechanism 12 that applies an inward biasing force to the heat sink 5.

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 posture, the connecting portion between the front end of the second rubber cord body 64 that is the inward biasing mechanism 12 and the hinge mechanism unit 4 is at the front position,
Since the second rubber string 64 is stretched, the first rubber string 63 that is the outward urging mechanism 11 is forcibly stretched to apply an inward force to the passive member 61. Therefore, the heat sink 5 moves inward along the upper surface of the heating element 6 in a state where the horizontal guide groove 5b is guided by the guide pin 23, and the radiation fins 5a of the heat sink 5 are connected to the through holes 7a of the casing 7. It is in a state immersed further inside. The first rubber cord body 63 and the second
The urging force to the contraction side is accumulated in the rubber cord body 64.

As the display unit 3 is opened and rotated about the hinge mechanism 4 as a fulcrum, the connection between the front end of the second rubber string 64 and the hinge mechanism 4 moves rearward, and the second Since the rubber string 64 contracts, the first rubber string 63 also contracts. Along with this, the heat sink 5 integrated with the passive member 61 slides backward on the upper surface of the heating element 6 with the horizontal guide groove 5b being guided by the guide pin 23, and opens the display unit 3 at a predetermined opening. When opened to the attitude, the radiating fins 5a of the heat sink 5 protrude outside from the through holes 7a, and the radiating fins 5a come into direct contact with the outside air.

As the display unit 3 is closed and rotated about the hinge mechanism 4 as a fulcrum, the connection between the front end of the second rubber string 64 and the hinge mechanism 4 moves forward, and the second rubber string 64 moves forward. Since the rubber cord 64 is stretched and the first rubber cord 63 is also stretched at the same time, and the passive member 61 is pulled forward,
When the display unit 3 is in the predetermined closed position, the radiation fins 5a are immersed in the casing 7 through the through holes 7a.

Also in the case of the fifth embodiment, the structure is relatively simple, and the burden on cost does not increase.

In any of the embodiments, the radiation fins 5a may be pin-shaped or plate-shaped.

According to the first aspect of the present invention, the radiating fins are made to protrude from the through hole into a state of contacting the outside air with the opening operation of the display unit and the closing operation. Since the radiating fins are configured to be immersed inside through the through-holes, the fins protrude outside from the through-holes and come into direct contact with the outside air when the display unit is in the open position, so that the conventional fixed heat sink is used. In this case, the heat radiation from the heat generating element through the heat sink and the heat radiating fins is sufficiently strong, and the thermally unstable operation of the heat generating element can be reliably eliminated. In addition, when the display unit is in the closed position when not in use, the radiation fins enter through the through-holes, so that the appearance does not need to be bad. In addition, when the information processing apparatus is moved or carried, it is possible to avoid a problem that the radiation fin hits another object and receives a mechanical shock to damage various internal electronic components and electric components.

In the information processing apparatus according to the second aspect of the present invention, the hinge mechanism of the display unit and the heat sink are interlockingly connected via the interlocking connection mechanism. The rearward sliding of the heat sink, which causes the radiation fins to protrude from the through-hole to the outside air, and the forward sliding of the heat sink, which causes the radiation fins to be immersed into the interior from the through-hole due to the closing operation of the display unit, under reliable power transmission. Satisfactorily.

In the information processing apparatus according to the third aspect of the present invention, the interlocking connection mechanism is constituted by the link bridgingly connected between the hinge mechanism and the heat sink. The structure of the mechanism for associating with the sliding of the heat sink can be extremely simplified, and the number of parts can be reduced.

In the information processing apparatus according to the fourth aspect of the present invention, the interlocking connection mechanism is constituted by a combination of the pinion gear mechanism provided on the hinge mechanism and the rack mechanism provided on the heat sink. ,
The structure of a mechanism for associating the rotation of the display unit with the sliding of the heat sink can be extremely simplified, and the interlocking operation can be made smooth.

In the display section opening / closing type information processing apparatus according to the fifth aspect of the present invention, when the display section is in the open position, the cam section provided on the hinge mechanism section resists the heat sink against the urging force of the urging mechanism. And push it outward, the radiating fins protrude outside through the through-hole and directly touch the outside air,
As compared with the case of the conventional fixed heat sink, the heat radiating action from the heat generating element via the heat sink and the heat radiation fins is sufficiently strong, and the thermally unstable operation of the heat generating element can be surely eliminated. In addition, when the display unit is in the closed position when not in use, the heat sink returns to the home position by the urging force of the urging mechanism and slides the radiating fins through the through-hole, so the appearance is not bad. In addition, mechanical shock from other objects can be avoided.

In the information processing apparatus according to the sixth aspect of the present invention, the urging mechanism is constituted by a compression spring interposed between the heat sink and the casing, and the heat sink is applied to the cam portion. Since the passive members that come into contact with each other are integrally provided, the structure of a mechanism for associating the rotation of the display unit with the sliding of the heat sink can be extremely simplified, and the operational feeling can be improved.

According to a seventh aspect of the present invention, there is provided a display section opening / closing type information processing apparatus, wherein a biasing mechanism is constituted by a compression spring interposed between a heat sink and a casing, and a biasing mechanism is provided between the cam section and the heat sink. Even if the damper mechanism is interposed, the sliding operation of the heat sink can be performed stably and smoothly even if the hinge mechanism is separated from the heat sink.

In the information processing apparatus according to the eighth aspect of the present invention, when the display unit is in the open position, the urging function of the inward urging mechanism is lost and the outward urging mechanism is not used. The heat sink slides outward due to the force, and the radiating fins protrude outside from the through-hole and directly come into contact with the outside air. In this case, the heat radiating action is sufficiently strong, and the thermally unstable operation of the heating element can be reliably eliminated. When the display unit is in the closed position when not in use, the biasing force of the inward biasing mechanism overcomes the biasing force of the outward biasing mechanism, the heat sink returns to the home position and slides, and the radiating fins pass through the through holes. Because of the immersion, appearance is not bad, and mechanical shock from other objects can be avoided.

In the information processing apparatus according to the ninth aspect of the present invention, since the outward urging mechanism and the inward urging mechanism are constituted by rubber strings, the structure is extremely simple. Thus, an increase in cost can be reduced.
