| Zusammenfassung: | The method is for adjusting the ejecting speed of a tray lower than the inserting speed. The circuit includes a feedback amplifier(14) for amplifying tray control signal from a microprocessor, a gain adjuster(14) connected in series with tray control terminals(A,B) to provide different gains at inserting and ejecting, and a gain adjuster(18) for controlling current flowing into a tray driving motor according to gains determined by the gain adjuster(14). |
