Abstract: There is provided a motor for a disk drive apparatus. The motor includes a cone member, a substantially annular back yoke, a substantially annular clamp magnet, an adhesive agent, and a motor unit. A storage portion includes a clamper insertion portion formed in a position axially overlapping with the clamp magnet to accommodate the clamper when the clamper comes closer to the cone member. The back yoke includes a first surface opposed to the clamp magnet in a contact or adjoining relationship therewith and a second surface positioned near the clamper insertion portion and kept spaced apart from the clamp magnet. The cone member includes an adhesive agent staying portion arranged to accommodate a part of the adhesive agent. The adhesive agent stays portion being defined between the imaginary surface extending axially downwards from the circumferential surface of the clamp magnet facing the clamper insertion portion.

Abstract: An integrated disk driving module is disclosed, the module including a base unit including a stepping motor fixture bent from an upper plate toward an accommodation space, wherein the stepping motor fixture is integrally formed with the upper plate, and a stepping motor rotatably fixed to the stepping motor fixture.

Abstract: An integrated disk driving module is disclosed, the module including a base unit including a spindle motor fixture including an opening-formed upper plate, a lateral surface plate bent from the upper plate to form an accommodation space, and a spindle motor fixture concavely formed from the upper plate toward the accommodation space, wherein the spindle motor fixture is integrally formed with the upper plate; and a spindle motor fixed inside the spindle motor fixture to rotate a disk.

Abstract: A traverse chassis supported in a swingable manner with respect to the main chassis and a disk transport plate provided along an opening are provided in the main chassis. The transport plate has a base part having a slender rectangular shape in plan view and a transport roller provided in the surface of the base part so as to extend in the longitudinal direction of the base part. The transport roller is provided such that its rotationally-moving shaft extends in parallel to an X direction, and an optical disk mounted on these components is loaded into or unloaded from an optical disk apparatus by rotation of the transport roller.

Abstract: A first groove, a second groove, and a prepared hole are formed in a traverse chassis. The first groove restricts the downward movement of a printed circuit board as a lower edge portion of the board is slidably pinched in the first groove. The second groove restricts the sliding movement in one direction of the board as an edge portion on one side of both lateral sides of the board whose lower edge portion is nipped in the first groove is fitted in the second groove. The prepared hole vertically penetrates a portion of the traverse chassis defining the first groove and is disposed adjacent to an edge portion on another side of the both lateral sides of the board whose edge portion on the one side is fitted in the second groove.

Abstract: There are provided a disc tray, a traverse unit, and a main chassis unit. The main chassis unit has a main chassis, which has, as observed when the traverse unit is in a stand-by position, a latch portion that engages with a projection portion of a sub rack and a stopper member that restricts the movement of the cam slider. The stopper member has a rotary shaft in the shape of a circular column, a lever portion which the projection portion makes contact, and a lock portion that makes contact with the cam slider and thereby restricts the sliding movement of the cam slider.

Abstract: A disc apparatus includes a casing having an opening for insertion/ejection of a disc, a rotator for clamping and rotating the disc, a disc-transferring member, a head facing a recorded face of the disc and being movable in radial directions of the disc, a rack movable together with the head, a first pinion gear engageable with the rack, a motor for driving the first pinion gear; and a switching member moving between a transmission position and a cut-off position. The switching member connects a power transmission path for transmitting a driving force of the motor to the disc-transferring member when the switching member is in the transmission position, and cuts off the power transmission path when the switching member is in the cut-off position.

Abstract: An optical disk drive includes a turntable, a first motor for turntable drive, an optical pickup and a drive mechanism arranged on a drive base and a separate traverse base that floats on the drive base. A loading drive mechanism drives a disk loading mechanism. A second motor can be driven in forward and reverse directions to supply drive power to the loading drive mechanism and a pickup drive mechanism. A drive power transfer path switching mechanism is used to switch the path through which drive power from the second motor is transferred to supply power to the loading drive mechanism and pickup drive mechanism. By continuously driving the second motor in one direction, then moving the optical pickup, raising or lowering the turntable, and transporting a disk can be accomplished in this sequence substantially continuously. By reversing the direction of motor drive, these operations can be accomplished substantially continuously in reverse direction in reverse sequence.

Abstract: The disk carrier device of the present invention comprises a carrier gear rotation-driven by a motor, control members driven by the motor via this carrier gear, for moving in one direction or in the other direction according to the direction of rotation of the motor, and a transmission gear which transmits the rotation of the motor to a feed roller. A rotation control section and a roller position control section are provided in the control member, respectively. At the time of ejecting the disk, with the movement of the control member, the feed roller is made to approach the disk guide by the roller position control section, and then the transmission gear is shifted to the transmission position by the rotation control section.
