The power supply switching unit 2 is a switch that switches whether the current to be supplied to the control unit 1 is supplied from the main power supply unit 3 or from the auxiliary power supply unit 4.

The main power supply section 3 consists of batteries, storage batteries, etc., and during normal use,
Current is supplied to the control unit 1 via the power switching unit 2.

The auxiliary power supply section 4 is made up of a battery or a storage battery, and is not normally used, but is switched to use by the power supply switching section 2 when the voltage of the main power supply section 3 drops. The auxiliary power supply section 4 has sufficient capacity to carry out processes that need to be performed before the power is turned off, such as saving files, even if the supply of current from the main power supply section 3 stops.

Next, the operation of this computer will be explained.

Normally, the power supply switching section 2 supplies current from the main power supply section 3 to the control section 1 . The control unit 1 controls input/output devices not shown in FIG.

While performing arithmetic processing, it also checks whether the voltage supplied from the main power supply section 3 is sufficient.

If the control unit 1 detects through a voltage check that the supply voltage from the main power supply unit 3 has decreased while using this device, making it difficult to continue processing, it will warn the user with a lamp, display, etc. is given.

The user may be unable to continue processing due to this warning.
Knowing that the power supply is about to be cut off, the user operates the power supply switching unit 2 to switch the current supply to the control unit 1 from the main power supply unit 3 to the auxiliary power supply unit 4. The control unit 1 uses this auxiliary power supply unit 4
This allows you to perform processes that would be problematic if a power outage occurs, such as saving files.

As described above, the present embodiment includes a control section, a power supply switching section, a main power supply section, and an auxiliary power supply section, and when the supply voltage of the main power supply section decreases, the power supply switching section switches the power source to the auxiliary power supply section.
