Abstract
A control unit makes the slot control mechanism execute an failure recovery operation to repeat the insertion operation and the ejection operation alternately for a predetermined amount at a first point of time when the below fact is found, if it is found that there is an error in insertion operation or ejection operation of a slot control mechanism. Afterwards, the control unit makes the slot control mechanism execute an restoration operation for a predetermined amount after a second point of time when the below fact is found, if it is found that the slot control mechanism has returned to normal, thereby making the slot control mechanism return to the state at the first point of time. Then, the control unit makes the slot control mechanism execute the insertion operation or the ejection operation again. With this arrangement, it is possible to ensure reliable insertion operation or ejection operation.
