    摘要： A disk drive apparatus includes a mainframe equipped with a disk table which is rotated by a spindle motor, a disk holder which is provided on the mainframe so as to be movable in the up and down directions and which is adapted to hold a cartridge of a floppy disk, and an eject plate which is provided on the mainframe so as to be movable in the forward and backward directions, wherein the disk holder is moved up or down in conjunction with the forward and backward movement of the eject plate. The disk holder up and down mechanism includes at least three pins provided on each of the side plates of the disk holder, and at least three guide portions which are provided on each of the side plates of the eject plate so as to correspond to the pins of the disk holder, respectively and which are adapted to be cooperatively associated with the corresponding pins, in which each of the guide portions is formed from either a first guide portion which has only a slanting cam surface which acts on the corresponding pin when the eject plate is moved from its first position to its second position, or a second guide portion which has only a slanting cam surface which acts on the corresponding pin when the eject plate is moved from its second position to its first position. If three pins are provided on each side plate of the disk holder, the corresponding side plate of the eject plate is formed with two first guide portions and one second guide portion positioned therebetween.

    摘要： A flexible disk drive includes a case and a disk holder provided in the case. A flexible disk is mounted on the disk holder. A part of the disk holder abuts against an inner face of the case. Preferably, the part of the disk holder is a tip end portion of the disk holder. The tip end portion of the disk holder is bent in a slanted direction so as to enlarge an inlet of the disk holder for the flexible disk to be inserted.

    摘要： A cam plate member 24 is provided such that it is supported by a lower chassis 8 so as to rotate freely and rotates in accordance with the inserting/ejecting operation of a disk cartridge 5. The cam plate member 24 includes an elastic cam lever portion 24f and a cam convex portion 24g which are formed integrally. The elastic cam lever portion serves to push up the disk cartridge thereby to prevent hitting between the disk cartridge and a magnetic head 6 until the disk cartridge 5 that is inserted is loaded to a recording/reproducing portion 17 after the state where the disk cartridge moves onto a guide convex portion 14 formed at the lower chassis 8. The cam convex portion serves to push up and hold a portion 28 of a holder 10 which holds and loads the disk cartridge 5 from a portion 4 of the recording/reproducing portion 17 thereby to prevent the cartridge holder from being bent due to vibration.

    摘要： A plurality of projected pieces 213 are provided on the surface of a main chassis 210 that is opposed to an eject plate 220 in such a manner that the projected pieces are adapted to guide sliding motion of the eject plate in contact therewith. The main chassis has first openings 214 formed therein at respective positions close to each projected piece on the main chassis. The first openings allow the sliding motion of the eject plate. First L-shaped members 222 are provided on the eject plate at positions corresponding to the first openings. The L-shaped members are each formed by means of cutting, depressing, and bending to extend from the back surface of the eject plate. Bent portions 222a of the first L-shaped members are passed through the first openings to guide the sliding motion of the eject plate along the back surface of the main chassis.

    摘要： A motor 40 for rotation driving a magnetic disk is comprised of a rotor 41 and a stator 42 assembled with the rotor. The rotor has a central cone 41-11 with a closed top at the center of a casing 41-1, the central cone having a trapezoidal configuration in cross section and being projected upward. A disk table 43 is fixed to the closed top surface of the central cone 41-11. A chassis 30 has an opening 30a formed therein through which only an upper portion of the central cone with the closed top of the rotor is projected towards the major surface. The disk table is thus attached to the back side of the chassis.
