(5) RC constituting a low-pass filter
This circuit is for removing a sudden change in an analog signal output from the current detection circuit (4) due to a sudden change in current consumption due to, for example, a disk mounted on the main body. This is because the drive voltage to the fan, which will be described later, is controlled in response to the analog signal.
If the circuit (5) is not provided, the drive voltage to the fan also changes abruptly due to the abrupt change of the signal. As a result, there is a risk that the supply voltage to the power supply unit (2) of the main body may drop instantaneously, causing a malfunction of the CPU or the like, and the RC circuit (5) is provided to eliminate such a fear.

(7) is a comparator, which outputs a low level signal when the output value of the amplifier (6) is less than a predetermined value, and outputs a high level signal when the output value is more than the predetermined value. The predetermined value is a value corresponding to a current value detected by the current detection circuit (4) when the extension board is not mounted. Therefore, when no expansion board is installed,
The output signal of the comparator (7) goes low, while it goes high when an expansion board is mounted.

According to the present invention, the attachment of the extension board is detected based on the detection result of the current consumption amount of the standard equipment circuit and the extension board, and the cooling means such as the fan is driven based on the detection result. Therefore, the cooling means can be driven only when necessary, and power is not wasted as in the conventional case. In addition, since the driving of the cooling means is controlled based on the amount of current consumption, fine control can be performed, and the power consumption can be further reduced. Further, since the detection result of the current consumption amount of the standard equipment circuit and the expansion board is outputted through the filter means, the drive voltage is rapidly supplied to the cooling means due to the rapid change of the current consumption by the disk or the like. Changes can also be prevented.
