Abstract
An information recording medium conveyer is provided, which provides countermeasures against power interruptions with high reliability. When a power interruption occurs during a loading operation with a conveying roller, the first unloading operation is initiated. When the outputs from detection sensors satisfy a predetermined condition during the first unloading operation, the process is initialized to cause the conveying roller to initiate a re-loading operation, thereby loading an information recording medium into a tray. On the other hand, when the outputs from the detection sensors do not change in accordance with a predetermined sequence during the re-loading operation, the process initiates the second unloading operation. When the detection sensors have detected the information recording medium during the second unloading operation and then the outputs from the detection sensors satisfy the predetermined condition, the process is initialized to cause the conveying roller to initiate another loading operation, thereby loading the information recording medium into the tray. Even when a power interruption occurs during an unloading operation, the same processing is performed to eject the information recording medium.
