摘要： In a disk drive apparatus for driving a CD or CD-ROM having a disk tray with a recess, the recess is provided with a plurality of pawls that keep the disk stable when it is loaded in the recess and the apparatus is vertical. In this way, unexpected contact of the outer circumference of the disk with the outer circumference of the recess is avoided. The recess is moreover provided with insulators that fully allow deformation or displacement of a base unit in one direction, but minimize it in other directions. External vibrations acting on the apparatus when it is vertical are therefore effectively damped, and rotation of the disk in the apparatus is steady.

摘要： Coil springs 96 and 97 are incorporated in a driving-side transmission mechanism 61 so as to absorb backlashes between a rack 55 and a drive gear 59a. Since the respective backlashes between the drive gear 59a and the rack 55 are absorbed by way of the coil springs 96 and 97, merely phase matching at the sole driving-side transmission mechanism 61 is required as phase matching work of toothed portions of gears during assembly, thereby simplifying the assembling task and shortening assembly time. Additionally, since a coil spring is not included in the rack 55, the rack can be designed to be small-sized in its width direction, thereby minimizing the moment of a force about the meshed engagement point, acting on an optical head carriage 53, and reducing transfer loss in the head.

摘要： A distributor cap has external terminals 23, 24 and inner electrodes 25, 26 disposed on a cap main body, and electrical conductors 28, 35 are embedded in the cap main body for sequential power distribution by a rotor of the distributor. Some of the conductors are coated with electrically insulating sheath members 36 which have insulating bridge members 38 bridging the sheath members on adjacent ones of the conductors. The bridge members have formed thereon positioning projections 37 for limiting the movement of the conductors out of predetermined positions during the molding of the cap body, whereby substantially no surface discharge occurs.

摘要： To perform ejection of a disk cartridge and head loading (landing) and/or unloading (takeoff) with a single driving source and prevent damage to a disk upon head landing and takeoff. A cam protrusion which is an outputting section of a geared motor is moved at a low speed and acts upon a head lifting mechanism by which, by rotation of the geared motor in one direction (CW direction), ejection of a cartridge is performed, but by rotation in the other direction (CCW direction), landing of magnetic heads is performed for head loading of the magnetic heads.
