<p>PURPOSE:To prevent such a write as to break down a file by monitoring whether an auxiliary storage device is exchanged or not during suspending. CONSTITUTION:A PC card loading/unloading monitoring part 15 always monitors two card detect signals CD1 and CD2 and reports the result to a CPU. A PC card 14 is internally grounded so that the card detect signals CD1 and CD2 can be effectively functioned. Since it is necessary to monitor the loading/ unloading of the card regardlessly of the operating state of an information processor 1, currents always flow to the pullup resistors of the card detect signals CD1 and CD2, and a current is continuously supplied to the loading/ unloading monitoring circuit 15 as well. Thus, the means is provided to monitor the ejection of a card/disk as the auxiliary storage device, when the auxiliary storage device is exchanged, the exchange is reported to the CPU just after resume, and the information to be recorded in the former storage device is recorded in the new storage device so that the contents can not be broken.</p> |
