Main Battery Exchange Mechanism Without Sub-battery

      Disclosed is a mechanism for keeping power supplied to a
system during exchange of a rechargeable/non-rechargeable battery
(main battery) without any other back-up batteries (sub-battery)
provided.  This mechanism, for example, is applicable to
battery-driven personal computers.

      The mechanism will be explained on a typical notebook-type
personal computer which has a rechargeable battery as shown in Fig.
1.  A battery lid 1 and a rechargeable battery 2 provide continuous
power supply function described above.

      Fig. 2a shows the mechanism of the battery lid 1.  A latching
rod 3 is to attach a battery to the battery lid 1. Two contacts 4a
and 4b are contact points to the battery, and the power from the
battery is supplied to a system through a power cord 5.  The
circuitry of those two contacts and the other two contacts, 4c and
4d, in the battery slot (shown in Fig. 4a) are shown in Fig. 2b.

      Fig. 3a shows the outline of the rechargeable battery 2.  Latch
holes 7 are to be latched by the latching rod 3 to fix the battery
to the lid 1. The two contacts 6a and 6b will contact 4a and 4b
on the battery lid 1, respectively, when the battery is attached to
the lid 1.  The other two contacts 6c and 6d will contact 4c and 4d
in the battery slot, respectively, when the battery is located in the
battery slot.  The internal circuitry of the rechargeable battery 2
is shown in Fig.  3b.
