    摘要: An optical disk reproducing device has a defect-signal generating circuit including a peak-holding-signal generating circuit for generating a peak-hold signal based on an RF signal read from a recording medium, an intermediate-signal generating circuit for generating an intermediate signal based on the peak-hold signal, a signal-level adjusting circuit for generating a threshold signal based on the intermediate signal, a threshold-signal adjusting circuit for adjusting the level of the threshold signal, and a comparator for generating a defect signal based on the peak-hold signal and threshold signal. The threshold-signal adjusting circuit includes at least one of: a first adjusting circuit for raising the threshold signal in the event the peak-hold signal falls below the threshold signal due to the peak-hold signal and the threshold signal being reversed; and a second adjusting circuit for lowering the threshold signal in the event the peak-hold signal exceeds the threshold signal, due to the reversal.

    摘要: An immediate printing type image forming apparatus is provided of which the warm-up time is sufficiently shortened without causing any trouble to occur in the execution of image reading processing and/or image forming processing. The image forming apparatus is configured to determine a time required to raise the current temperature of the surface of a heating roller in a fixing unit to a predetermined temperature and increase the duty ratio of a power waveform to be fed to each of a copy lamp and a motor driving a polygon mirror when the time required thus determined is shorter than each of a time required to increase the current light quantity of the copy lamp to a predetermined light quantity and a time required to raise the current rotational speed of the motor to a predetermined speed, thereby turning each of the copy lamp and the motor into respective predetermined condition before the elapse of the determined time required.
