摘要： The invention makes it possible to carry out an emergency eject motion without attaching and detaching teeth between gears in a transmission system of a driving force of a loading motor, in an optical disc apparatus. At least one of gear units in a gear train constructing a transmission system between a loading motor and a disc moving mechanism is structured such that a driving gear is coupled in an inner diameter side of a large diameter driven gear in such a manner as to be movable in an axial direction and be rotatable integrally with the driven gear, and the driving gear moves and displaces in an axial direction with respect to the driven gear, thereby being canceled the coupling with the driven gear while keeping an engagement with a gear in the next stage, canceling the coupling by an external force by a manual operation so as to set the transmission system to a disconnection state at a time of an emergency eject, making the disc moving mechanism carry out a disc discharge motion by the external force, and discharging an optical disc out of the apparatus.

摘要： A brushless motor includes a minimum number of parts and is assembled easily. A molded, substantially annular plastic permanent magnet on a rotor is magnetized in axially opposite directions alternatively such that a plurality of pairs of S and N poles are formed alternatively. The substantially annular permanent magnet includes an annular portion associated with air-core coils provided on a stator for generating a driving torque for the rotor and associated with a frequency signal generating circuit pattern provided on the stator for generating an electric signal indicative of a rotor speed and a protruded portion protruding from an outer peripheral side surface of the annular portion and associated with a rotor position detecting means provided on the stator for generating an electric signal indicative of a rotor position. A boundary line between an S and N pole of one of the plural pole pairs passes through the protruded portion. Lead portions for connecting terminals of the frequency signal generating circuit pattern to external circuits are formed such that they are overlapped to prevent degradation of frequency signal generator characteristics.
