2. Description of the Related Art With the recent technological innovation, various personal computers (PCs) such as a desktop type, a tower type, and a notebook type have been developed and marketed. Among them, the notebook PC is designed and manufactured to be small and light in consideration of a mobile environment, that is, portable and portable use outdoors.

FIG. 10 shows a typical notebook PC. As shown in FIG.
Are system boards and external storage devices (for example, HDD
Or FDD), and a so-called “clam shell” structure including a PC body 2 having a built-in PC and a lid 3 rotatably supported at a substantially rear edge of the main body. A keyboard unit 2A is provided on the upper surface of the main body 2, and a liquid crystal display (LCD) unit 3A is provided inside the lid 3. When not in use or during transportation, by closing the lid 3, the keyboard unit 2A and the LCD unit 3A are protected by a robust housing.

One of the features of the notebook PC is that it is a "battery-driven type" in which power can be supplied by a built-in battery. This is because the PC can be used in places where commercial power is not always available, such as outdoors or on a business trip. The built-in battery generally takes the form of a “battery pack” in which a plurality of battery cells are packaged. Also, the battery cells include:
Usually, a rechargeable type such as Li-Ion or NiMH is used.

The battery pack has a generally flat shape and is set in a dedicated storage space provided in the notebook PC main body 2. For example, a notebook PC "IBM T" marketed by IBM Japan, Ltd.
hinkPad 760 "(" ThinkPad "is a US I
When the keyboard unit 2A is of a type that can be opened and closed with respect to the PC main body, such as a trademark of BM, the battery 5A in the battery storage space 4A inside the PC main body 2 is opened by opening the keyboard unit 2A. Can be accessed (see FIG. 11).

On the other hand, in the case of a model in which the keyboard unit 2A cannot be opened, for example, as in a notebook PC "IBM ThinkPad 560" marketed by the company, a battery housing of a shallow bottom shape is provided on the bottom of the PC main body. 4
B is recessed. By turning over the PC main body 2, the battery storage section 4B can be accessed, and the battery pack 5B can be inserted through an opening provided on the wall surface of the PC main body 2 (see FIG. 12). Further, by operating a slide knob 6 provided around the battery storage section 4B, the battery pack 5B is locked at a fixed position by a locking mechanism (not shown). By operating the slide knob 6 in the opposite direction, the locked state is released and the battery pack 5B can be replaced. In such a case, a part of the side wall of the battery pack 5B is exposed from the PC main body 2 even in the mounted state, and also constitutes a part of the notebook PC main body 2.

Incidentally, the battery packs 5A and 5B for the notebook PC include about 10 battery cells in order to support a driving time of about several hours. In other words, the battery packs 5A and 5B
The weight of the C body 2 is about a fraction of that of the C body 2, and the volume /
Very high energy density per capacity. For this reason,
Care must be taken when handling the battery packs 5A and 5B.
Not only may the covers of A and 5B be damaged or the user be injured, but also there is a danger of short-circuiting between the battery terminals due to the incorporation of metallic foreign matter, causing fire or explosion. Therefore, securely fixing the battery packs 5A and 5B to the battery storage unit is one of the important items in designing a notebook PC.

[0008] A notebook PC of the type in which the keyboard unit 2A is opened (for example, "IBM Thin")
In the case of kPad 760 "), the keyboard unit 2A itself is firmly fixed to the PC body,
The problem of falling off of the battery pack 5A will be relatively easily solved. However, when the battery storage section 4B is of a type that is recessed in the bottom surface of the notebook PC main body 2, it does not go straightforward. This is because the opening of the battery storage section 4B is open downward, that is, in the direction in which the battery pack 5B is dropped, and the slide knob 6 for releasing the locked state of the battery pack 5B is disposed on the bottom face. And the fact that a part of the side wall of the battery pack 5B constitutes a part of the notebook PC main body 2 and is susceptible to an external impact.

For example, if the finger holding the PC main body 2 unknowingly operates the slide knob 6 while the user is carrying the notebook PC, the battery pack 5B may fall. In particular, since the slide knob 6 is operated in the direction along the bottom surface of the PC main body 2, erroneous operations occur relatively easily.

Also, when the notebook PC is taken in and out of the bag, the slide knob 6 may be caught on a peripheral object and operated.

When the notebook PC is used inadvertently without locking the battery pack 5B,
The battery pack may fall off when the PC body 2 is lifted.

A person skilled in the art is relatively skilled in the art of double locking, in which a locking mechanism for prohibiting the operation of the slide knob 6 is separately attached in order to strengthen the locking of the battery pack 5B. It could be easily created. In this case, the lock mechanism may have a structure in which, for example, a bar is inserted in the operation direction of the slide knob 6 (not shown). However, replacement of the battery pack 5B requires a dual operation of releasing / setting the lock and releasing / setting the lock, which is not easy for the user.

If the user forcibly pushes the pack into the battery storage section 4B, forgetting that the locking mechanism and the lock mechanism are biased and cannot be attached or detached, the peripheral parts of the storage section may be damaged. It could be.

Further, the sliding portion 33 is operable in the longitudinal direction, but the operating distance is limited to a range in which the latches 34a, 34b can move in the linear grooves 26a, 26b.

The operating portion 31 is a portion for operating the lock release prohibiting portion 30 by being pinched by a user, and has a pair of curved portions formed at both ends for scratching the claws. The operation of the unlocking prohibition section 30 referred to here means that the unlocking prohibition section 30 is made to protrude and retract, and further, the unlocking prohibition section 30 integrated with the locking section 20 is operated in the direction opposite to the arrow P. Refers to

An opening 32 is formed in the operation section 31. The substantially triangular opening 32 has substantially the same dimensions as the outer shape of the projection 27 on the locking portion 20 side, and the unlocking prohibition portion 30.
Is disposed at a position for receiving the protrusion 27 at a position where the protrusion 27 is completely buried. By fitting the projection 27 into the opening 32, the sense of unity between the lock release prohibition portion 30 and the lock portion 20 is enhanced. The triangular direction of the opening 32 implies an operation direction for releasing the locked state.

FIG. 4 illustrates a cross section around the locking portion 20 when the battery pack 80 is mounted on the battery storage unit 10.

As shown in the figure, the lock release prohibition portion 30 is completely buried in the receiving portion 25, and only the operation portion 31 is exposed.

A rotational force in the direction of arrow P in the figure is applied to the locking portion 20 by the coil spring 24, whereby the latches 22 a and 22 b are engaged with the engaging portions 83 provided on the side wall of the battery pack 80. And the battery pack 80 is prevented from falling off.

When the locking portion 20 escapes in the anti-P direction, the engaged state by the latches 22a and 22b is released. However, in this state, the operation unit 31 is
2, and the movement in the direction opposite to arrow P is strictly prohibited.

FIG. 5 shows how the battery pack 80 is released from the lock release prohibition state.

As shown in the figure, when the user grips the operation section 31 and pulls it up, the linear grooves 26a, 26b
The operation unit 31 is raised within a range in which the movement of the hell latches 34a and 34b is permitted. As a result, the operation unit 31 is separated from the edge of the depression 12 and can be rotated in the direction of the arrow P.

Next, as shown in FIG. 6, when the operation section 31 is tilted and tilted in the direction opposite to the arrow P, the latches 22a, 22
