2. Description of the Related Art In recent years, many portable electronic devices have been released, and advanced electronic devices equipped with a CPU (Central Processing Unit) have appeared. A large amount of power is consumed to drive such an electronic device. Among portable electronic devices, for example, a portable computer includes a main body and a display unit thereof, and the display unit can be opened and closed with respect to the main body via a hinge. A typical example of such a portable computer is a computer called a notebook personal computer.

In order to drive the main body of this type of portable computer and its display unit, a battery is mounted. In such batteries, a battery pack is set, for example, outside the main body in order to drive the main body and its display unit. The capacity of the battery pack is large to small. In order to increase the capacity of the battery pack, since many battery cells (single batteries) are mounted, the external shape is large and heavy. In addition, a battery having a small capacity has a relatively small outer shape and light weight because the number of mounted battery cells is small. In a battery pack having a large capacity, the number of battery cells to be mounted is large, so that battery cells are generally arranged in a plurality of rows. A portable computer provided with this type of battery pack is disclosed in Japanese Patent Application Laid-Open No. 8-76898. Disclosed Battery Pack 2004

Even if the display unit 3 is rotated by 180 degrees or more in the R direction with respect to the main body 2, the display unit 3 does not contact the long battery unit 220, and the display unit 3, the battery pack 200, and the main body 2 2 can be prevented from being damaged, the battery itself being damaged, and the display unit being damaged.

FIG. 8 shows the shape of the battery pack 200 of FIG. 7 in more detail. The short battery section 210 incorporates, for example, two battery bodies 210A,
Although not shown, 20 incorporates, for example, three battery bodies. FIG. 13 shows the protrusion 22 near the battery body 210A.
1 and the like are shown. This projection 221 is
0, 220 are connected, and a circuit board 299 is disposed in the case of the battery unit 210.

As shown in FIGS. 9 and 10, the long battery section 220 has non-slip 235 and 235. The slip stoppers 235 and 235 are made of, for example, rubber having a large frictional resistance. In this way, non-slip 235
The reason for providing the 235 is to ensure that the tilt support function of the main body as shown in FIGS. 14, 15 and 16 is exerted.

In FIGS. 14 and 16A, for example, when the display unit 3 is stored in a folded state with respect to the main body 2 or is carried, the long battery unit 220 and the short battery unit 210 are connected to the main body 2 and the short battery unit 210. They are arranged in the direction of arrow N along the front-back direction of the display unit 3. On the other hand, FIG. 15 and FIG.
When the computer 100 is actually used on a desk or the like, the display unit 3 is opened from the main body 2 in the direction of arrow R as shown in FIG.
The long battery unit 220 is rotated about 90 degrees with respect to 0 and used. As a result, only the long battery portion 220 moves below the rear end 2F of the main body 2, so that
The rear surface 2F of the support surface S by a height corresponding to the predetermined height K.
Can be lifted above P. By doing so, the operability of the keyboard 4 of the main body 2 is improved, and the user can easily use the computer 100. At this time, since the non-slip 235 is in contact with the support surface SP, the computer 100 itself does not easily move. In this case, only the short battery part 220 needs to be rotated, and the battery pack 2
It is not necessary to rotate the entire 00 with respect to the main body 2, so that the operation is easy.

FIG. 17 shows one connecting portion of the battery units 210 and 220 and the rotation preventing mechanism 450. In the vicinity of the protrusion 221 of the battery unit 220, the unlock slider 400 is attached to the recess 401 of the case of the battery unit 210.
Is located inside. This unlock slider 400
Can forcibly move the stopper member 402 in the direction of arrow F. The stopper member 402 is pressed in a direction opposite to the arrow F direction by a biasing means 404 such as a spring against the fixing portion 210R of the battery portion 210. Thus, the stopper member 402 protrudes from the hole 405 of the case of the battery row 201 toward the protrusion 221. The stopper member 402, the unlock slider 400, the biasing means 404, and the like constitute a rotation prevention mechanism 450 that prevents the long battery section 220 from rotating in the S direction with respect to the short battery section 210.

The rotation preventing mechanism 450 is further provided in FIG.
And a hole 451 as shown in FIG. This hole 451 is formed in the projection 221. This hole 4
The stopper member 402 fits into the position 51 at a position where the long battery section 220 is rotated by 90 degrees in the S direction with respect to the short battery section 210 (see FIG. 15). With the stopper member 402 fitted in the hole 451 in this manner, the user moves the unlock slider 400 to the F position.
The stopper member 402 in the hole 4
51 can be escaped.

Next, an example of the operation of the rotation prevention mechanism 450 will be described with reference to FIGS. As shown in FIG. 14 described above, when the long battery section 220 is parallel to the short battery section 210, the main body 2 and the battery sections 210 and 220 are placed side by side with respect to the support surface SP. . When the rear end of the main body 2 is lifted from the support surface SP and supported as shown in FIGS. 14 and 15, the long battery unit 220 rotates 90 degrees with respect to the short battery unit 210 as described above. .

FIGS. 19 and 17 show the positional relationship between the battery units 210 and 220 shown in FIG. in this case,
The stopper member 402 is in contact with the front surface of the protrusion 221 provided on the short battery portion 220. When the user wants to lift and support the rear end 2F of the main body 2 as shown in FIGS. 14 to 15, as shown in FIGS.
It gradually rotates in the direction. At this time, since the projection 221 forcibly pushes the stopper member 402 of the rotation preventing mechanism 450 in the F direction, the stopper member 402 retreats from the projection 221 and enters the hole 405.

Since the stopper member 402 is formed in a triangular shape as shown in FIG.
Is rotated, the protrusion 221 causes the stopper member 4
02 is pushed in the F direction. As the stopper member 402 is pushed into the hole 405, the long battery portion 22
When 0 rotates in the S direction with respect to the short battery unit 210, the long battery unit 220 is rotated by approximately 90 degrees with respect to the short battery unit 210, as shown in FIG. This situation is shown in FIGS. 21 and 22. In such a state where the battery is substantially rotated by 90 degrees, the long battery unit 220
The hole 451 of the projection 221 provided in the
By the force of 4, the stopper member 402 is fitted. Thus, when the long battery portion 220 shown in FIG. 15 is upright, the locking function is automatically performed so that the long battery portion 220 does not return to the original direction due to the action of the stopper member 402 shown in FIGS. Therefore, the rear end 2F of the main body 2 is
The battery can be reliably held inclined with respect to P, and the trouble that the battery row 220 returns to the original state during operation of the computer and the rear end portion 2F suddenly falls can be avoided.

When the user returns the main body 2 from the state shown in FIG. 15 to the state shown in FIG. 14, the user slides the unlock slider 400 shown in FIGS. And the stopper member 402 is forcibly
Get out of 51. Thus, the user can return to the state of FIG. 14 by rotating the long battery unit 220 with respect to the short battery unit 210 by approximately 90 degrees in the direction opposite to the S direction.

Next, FIGS. 4, 5 and 23 show a central processing unit (CP) as a heat generating source in the electronic apparatus of the present invention.
U) 35, a case (housing) 2B of the main body 2, one hinge 1B, a case (housing) 3A of the display unit 3, and the like. In FIG. 4, the central processing unit 35, which is a heat generation source,
Heat generated by the drive of the central processing unit 35
2 shows an example of a process of dissipating or dispersing heat from the substrate 36 on which is mounted on the case 3A side of the display unit 3 via the hinge 1B and the like. Specifically, a substrate 36 is disposed in the case 2B of FIG. 23, and a central processing unit 35 is mounted on the substrate 36. On the other hand, the case (housing) 3A and the case (housing) 2B are connected to hinges 1A and 1B (hinge 1A).
(Not shown) are mechanically connected so as to be openable and closable, and the heat of the central processing unit 35 is transferred to the case 2B and the substrate 3.
Thermal conduction is made from the 6 side to the case 3A side.

In the examples shown in FIGS. 4 and 5, since the central processing unit 35 is disposed substantially at the center of the substrate 36, there is a space between the central processing unit 35 and one of the hinges 1B. Therefore, the central processing unit 3
On the fifth side, a heat receiving plate 37 receiving heat from the central processing unit 35, a heat pipe 38, and a connector 39 are arranged between the hinge 1B and the central processing unit 35. The heat receiving plate 37 is disposed above the central processing unit 35 at, for example, a predetermined interval. The heat receiving plate 37 and the connector 39 are connected by a heat pipe 38. The heat pipe 38 and the heat receiving plate 37
Can be made of a metal having good thermal conductivity, for example, copper. The size of the heat receiving plate 37 is set larger than the size of the central processing unit 35.

The connector 39 is also made of a material having good heat conductivity,
For example, the case 2 of the main body 2 is made of copper, and furthermore, a screw 31 is used for the fixing piece 11 side of the hinge 1B.
Can be fixed to B side. On the other hand, the movable piece 17 side of the hinge 1B is fixed to the inside of the case 3A by a screw 32. The hinge 1B has a function of efficiently conducting heat from the fixed piece 11 to the movable piece 17 as described later.

Here, with reference to FIG. 23, how to transmit heat generated by the central processing unit 35 to the case 3A will be described. When the central processing unit 35 is driven and generates heat, the heat receiving plate 37 moves along the arrow AL1 to the central processing unit 3.
Receive 5 heat. The heat receiving plate 37 transmits the received heat to the fixed piece 11 side of the hinge 1B via the heat pipe 38 and the connector 39 along the arrows AL2, AL3, and AL4. Thereby, heat is transmitted along the AL5 from the fixed piece 11 side of the hinge 1B to the movable piece 17 side, and then this heat is transmitted to the case 3A side as indicated by an arrow AL6. As a result, the transmitted heat is radiated or diffused to the case 3A along the arrow AL7.

As described above, by transmitting heat from the main body 2 having a relatively large heat generation rate to the display section 3 having a relatively small heat generation amount, the computer 10 serving as the electronic apparatus 1 is heated.
The heat can be easily diffused or dispersed toward the display unit 3 by preventing the heat from stagnation in the main body 2 at 0. As described above, heat can be easily dispersed only by using a hinge without providing a special heat sink or a conduction fan.
