Abstract

A drive gear capable of being meshed smoothly with a mating gear and a disk device with the drive gear. A pinion gear (610) comprises a generally cylindrical body part (611) and a large number of teeth (612) provided on the outer peripheral surface of the body part (611) and having two opposed contact faces (613, 613) and serves as a drive gear. The pinion gear (610) is fixed, which is one of the method gears: the pinion gear and a large gear of a first gear (630) mating with the pinion gear (610). The large gear (631), or the other gear, is moved axially to mesh the gears with each other. Guide faces (614) to guide the teeth of the large gear (631) to the contact faces (613, 613) are provided at least at one end part of the teeth (612) of the pinion gear (610).

Description

technical field [0001] The present invention relates to disk devices, such as drive gears loaded with drive disk trays and devices equipped with the [0002] Disk device that drives gears. Background technique [0003] Figure 57 (a) and (b) are respectively the top view and the side view of the driving gear in the prior art. Figure 58 It is an explanatory diagram showing the positional relationship when the conventional drive gear is mounted on the mating gear. [0004] The driving gear 78 of the spur gear used in the disc tray opening and closing structure of the prior art disc device, etc. is formed of resin or the like, such as Figure 57 As shown in (a) and (b), it includes a body part 781 that is inserted through the motor and the rotating shaft is basically cylindrical, and on the outer peripheral surface of the body part 781, a plurality of It is a gear 782 extending linearly. [0005] Such a drive gear 78 may have protrusions such as burrs on the end surfaces of...
