Abstract: In a storage sub-system adopting a redundant configuration for preventing data loss and continuing processing during failure, when failure occurs, a controller unit in which failure has occurred is blocked so as not to affect the normal controller unit, so that the performance of the storage sub-system is deteriorated and the redundancy thereof is lost until maintenance and component replacement is performed.

Then, the blocked area is reconnected to the storage sub-system, so as to prevent deterioration of performance and overload of the device until maintenance and replacement is performed, and to reduce the time of failure analysis during maintenance by specifying the detailed failure area via self diagnosis.

The pressure varying mechanism has a rotating lever that switches the load pressure, a rotating arm that contacts and presses against a swinging arm of the pickup roller, and a biasing portion that biases the rotating arm to the swinging arm when the rotating arm contacts to the swinging arm. When continuously reading a wad of originals in which different-size originals are mixed, due to a user operating the rotating lever, the load pressure to the originals is increased by making the rotating arm contact to the swinging arm such that the swinging arm is pressed by the biasing portion.

Abstract: A signal conversion circuit 2 comprises a differential amplifier portion 10 and a source follower portion 20. When differential voltage signals INp and INn are input to a first input terminal 5 and second input terminal 6 respectively, operations occurs either in a mode in which only the differential amplifier portion 10 operates, or a mode in which both the differential amplifier portion 10 and the source follower portion 20 operate, or a mode in which only the source follower portion 20 operates, according to the levels of the differential voltage signals INp and INn. The differential amplifier portion 10 and source follower portion 20 have fewer components compared with a circuit comprising two differential amplifier circuits. By this means, the circuit area can be reduced, and in addition current consumption can be reduced. Also, because the source follower portion 20 performs non-inverting amplification of the differential voltage signals INp and INn, high-speed operation is possible.
