摘要： 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.

摘要： During an ejecting or unloading operation of an information recording medium by a conveying roller, if detection signals are output from detecting sensors indicating that the object being ejected or unloaded has already been discharged from an insertion hole although it has not, then the insertion hole is closed by the door. If, for some reasons, the door fails to close the insertion hole within a predetermined time, the conveying roller performs a forcible ejecting operation, whereby the object left inside is forcibly ejected to the outside. Thus, ejection or unloading of a medium is carried out without failure.

摘要： Two sum output signals from two sets of the photodetector elements located symmetrically each other with respect to a light-receiving center of the photodetector of the optical pickup are amplified individually by two amplifiers. A focus error signal is generated in accordance with a difference between respective output levels of the two amplified signals. The gains of the two amplifiers are adjusted in accordance with the focus error signal. A predetermined bias voltage is applied to the focus error signal line in the focus servo control means in accordance with the focus error signal.
