Next, a method of using the notebook computer 1 will be described with reference to the drawings.

For example, when using the power supply of the battery pack 3, the battery pack 3 is mounted on the power supply mounting section 13 of the personal computer body 2 as shown in FIG. In this case, the connector 2 is inserted into the mounting recesses 14a and 14b of the power supply mounting section 13.
When the battery packs 3 and 26 are inserted, the fixing claw portions 41 and 41 engage with the fixing holes 42 and 42 of the mounting recesses 14a and 14b, respectively.
Fixed to At the same time, the connection terminal 17 of the connector 17

g are connected to each other. Thereby, the connector 2
A DC voltage is supplied from the secondary battery 22 to the electronic circuit unit 12 via the terminals 5 and 17. In this case, the electronic circuit unit 12
Since the connection terminal 18c is connected to the ground potential via the connection terminal 26c, the connection of the battery pack 3 is recognized, and based on the voltage V1 input through the connection terminals 26a and 18a, The remaining capacity of the secondary battery 22 is detected.

At the time of operating the keyboard, when the battery pack 3 is rotated about the rotation axis T1 in the direction of the arrow A shown in FIG. 3A, as shown in FIG. 3B and FIG. The battery pack 3 protrudes from the bottom surface side of 2. In this state, the personal computer main body 2 is supported by the front end portion of the personal computer main body 2 and the lower surface of the battery pack 3, so that the personal computer main body 2 is slightly inclined to facilitate the key operation of the keyboard, and the rubber for preventing slippage. The board R prevents the displacement of the notebook computer 1.

On the other hand, when using the AC adapter 5,
As shown in FIG. 8, A
Connect the C adapter 5. In this case, the connector 27 of the battery pack 3 is connected to the connector 3 of the AC adapter 5.
By connecting the connectors 5 and 36, the fixing claws 41 and 41 of the connectors 35 and 36 are engaged with the fixing holes 42 and 42 of the connectors 27 and 28, and the AC adapter 5 is fixed to the battery pack 3. As a result, the DC voltage generation circuit 32 and the electronic circuit unit 12 are connected via the battery pack 3,
A DC voltage is supplied from the DC voltage generation circuit 32 to the electronic circuit unit 12. At the same time, the electronic circuit section 12 connects the connection terminal 36g of the connector 36 in the AC adapter 5 and the connection terminal 18g of the connector 18 to the ground potential via the relay cable 29g in the battery pack 3;

The charging of the secondary battery 22 by the adapter 5 is completed.

Thus, in the notebook computer 1,
Since the AC adapter 5 is connected via the connectors 25 and 27 and the connectors 26 and 28 of the battery pack 3,
As a result, there is no need to provide a connector for connecting the AC adapter 5 to the personal computer main body 2, so that the personal computer main body 2 can be made smaller than the conventional personal computer main body 52. Also,

Since the connection terminal 18g of the connector 18 is connected to the ground potential via the relay cable 6g and the relay cables 29g in the battery packs 3 and 4, the attachment of the AC adapter 5 is recognized. Next, the electronic circuit unit 12 connects the voltage V1 of the battery pack 3 input via the connection terminal 18a to the connector 18 via the relay cable 29d in the battery pack 3.
The remaining capacity of the rechargeable batteries 22, 22 in the battery packs 3, 4 is detected in accordance with the voltage V2 of the battery pack 4 input to the connection terminal 18d. Subsequently, for example, when charging the secondary battery 22 of the battery pack 4, the electronic circuit unit 12 outputs an ON signal SON to the connection terminal 18 e of the connector 18. As a result, the ON signal SON is output to the switch unit SW via the relay cable 29e in the battery pack 3 and the connection terminal 26e of the connector 26 in the battery pack 4. As a result, the switch unit SW is turned on, and the secondary battery 22 of the battery pack 4 is charged by the AC adapter 5.

In the notebook computer 1, the battery pack 4 can be connected to the battery pack 4 with the battery pack 4 mounted on the personal computer body 2. Further, the AC adapter 5 can be directly mounted on the power supply mounting section 13.
