JPH05342162A - Containing structure of ac adaptor in portable electronic apparatus - Google Patents

Abstract

PURPOSE:To enable to hande in a narrow place, and also, to miniaturize by constituting the AC adaptor so that it can be used as a battery pack by forming it in a shape almost the same as a battery pack. CONSTITUTION:In the portable electronic apparatus such as a computer, a word processor, etc., driven by a battery, an AC adaptor 18 is constituted so that it can be used in a battery containing chamber 7 by forming it in a shape almost the same as a battery pack. At the time of battery operation, the battery pack is inserted into the containing chamber 7 from a side part of a main body 1 and contained in freely attachable to and detachable from the containing chamber 7. At the time of AC operation, the battery pack is drawn out, and the AC adaptor 18 is set in the containing chamber 7 instead of the battery pack. In such a way, even when the AC adaptor 18 is used, it is unnecessary to place it separately from the main body 1 of the computer and the word processor, etc., and the AC adaptor 18 can be used in a state of being contained completely like the battery pack.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for accommodating an AC adapter in portable electronic equipment such as battery-operated computers, personal computers and word processors.

[0002]

2. Description of the Related Art Conventionally, portable electronic devices such as computers, personal computers and word processors have been operated by using an external power supply device such as an AC adapter. On the other hand, since the power supply is miniaturized, it is powered by the battery pack, and it is further miniaturized if the battery pack itself is housed in, for example, a portable personal computer or a word processor body. Is. Therefore, when it is stored in a portable personal computer or a word processor main body, the structure is such that it is fixed and held in the stored state and can be removed.

FIG. 4 is a perspective view showing a conventional example of a portable personal computer. A battery pack 23 is provided with a storage chamber 22 in the main body 21 of the personal computer, and the battery pack 23 is inserted into the storage chamber 22 for storage. To be done. On the other hand, A
The C adapter 24 is placed outside the personal computer body 21, is connected to the personal computer body 21 by a connecting cord 27, and is connected to an external power source (not shown) by inserting a plug 25 of a power cord 26. is there.

[0004]

Conventionally, since the AC adapter is provided separately from the computer, the personal computer and the word processor main body as described above, a table to be placed separately from the main body such as the computer must be prepared. Therefore, when working, it is necessary to provide a place for an AC adapter, which causes a space problem, and is contrary to the current trend toward miniaturization.
There are problems such as being extremely uneconomical requiring an adapter. As a result of earnest efforts to solve the above problems, the inventors have made it possible to insert the AC adapter into the main body of a computer or the like by forming the AC adapter into substantially the same shape as the battery pack.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides an AC power supply for a battery-driven electronic device.
It is characterized in that the adapter is formed in substantially the same shape as the battery pack so that it can also be housed as a battery housing part.

[0006]

Since the AC adapter is formed to have substantially the same shape as the battery pack so that it can also be housed in the battery housing, the AC adapter can be housed in the battery housing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention applied to the portable personal computer shown in FIGS. 1 to 3 will be described in detail below. 1 to 3 are perspective views showing a main part of an embodiment of the present invention, in which a personal computer contains various parts and circuits, a main body 1 having an input surface 2 for a keyboard 3, and a liquid crystal display. A display surface 5 such as the above is provided, and is composed of a lid body 4 pivotably supported on the keyboard 3 so as to be laid down.

First, the case of battery operation will be described. This personal computer has a built-in battery, and the battery pack 6 is inserted and stored in a storage chamber 7 provided so as to be stored in the bottom portion from the side surface of the main body 1. That is, the storage chamber 7 has an opening 7a on the side surface, and the battery pack 6 can be inserted and stored through the opening 7, and the storage chamber 7 is detachable.

As shown in FIG. 1, a lid 8 is provided in the opening 7a of the storage chamber 7 so as to be openable and closable. When the battery pack 6 is inserted, the lid 8 is opened, and after the insertion, the battery 8 is closed. The pack 6 is prevented from slipping out.

In the present embodiment, the lid 8 is detachably provided in the opening of the storage chamber 7, and the guide pieces 8a are provided on both the left and right sides so as to project, and the hooking projection 10 is provided at the lower end. ing. On the other hand, guide grooves 11 are provided on the left and right facing surfaces of the opening of the storage chamber 7, and locking grooves 12 are provided on the lower surface of the opening.
In the lid 8, the guide piece 8a is fitted along the guide groove 11,
It is attached by fitting the locking projection 10 into the locking groove 12.

A contact 9 is provided on the battery pack 6 so that when the battery pack 6 is housed in the storage chamber 7, it is connected to a connection portion (not shown) provided in the storage chamber 7 and connected to a circuit.

When the battery pack 6 is stored in the storage chamber 7, it is locked by the lock mechanism 13. The lock mechanism 13 is provided with a claw portion 15 at the tip of a lock lever 14, while the battery pack 6 is provided with an engagement groove 16 having a locking step portion 16a, and the claw portion 15 of the lock lever 14 is a battery pack. When the pack 6 is stored, it can be engaged with and disengaged from the engaging groove 16. This lock lever 14
A spring 17 that urges the claw portion 15 to maintain the engaged state when the claw portion 15 engages with the engaging groove 16 is provided in the and, and the locked state is maintained.

That is, the battery pack 6 is stored in the storage chamber 7
When inserted and stored in the lock lever 14, the claw portion 15 of the lock lever 14 engages with the engagement groove 16 of the battery pack 6, and the locking step portion 1
The removal of the battery pack 6 is locked by 6a.
However, when the lock lever 14 is moved in the direction of the arrow against the biasing force of the spring 17, the claw portion 1 of the lock lever 14 is moved.
5 and the engagement step 16a of the engagement groove 16 are disengaged and the lock is released.

Next, the AC operation will be described. As shown in FIGS. 2 and 3, the battery pack is removed and the AC adapter 18 is mounted in the storage chamber 7 instead. That is, by making the AC adapter 18 have substantially the same shape and size as the battery pack, both can be stored in the storage chamber 7 and used together. By doing so, even when the AC adapter 18 is used, there is no need to separate it from the main body of a computer, word processor, etc., and the AC adapter 18 is used completely in the same state as the battery pack 6. Is what you can do. Although not shown, the AC adapter 18 is also configured to connect the connection portion (terminal) and the contact 19 in the main body 1 when the AC adapter 18 is stored, like the battery pack 6.

[0015]

As described above, according to the present invention, a table for separately mounting an AC adapter has been conventionally required. It is possible to work in a small space, and it is possible to further reduce the size, which is very economically advantageous.
