Abstract

A disc drive apparatus is comprised of an opening portion which can insert / eject a large disc shaped medium and a small disc shaped medium, a feeding roller which pulls in a disc shaped medium being inserted to the opening portion, oscillating links which have convex portions against which an end surface of the disc shaped medium which is guided inside the apparatus by the feeding roller, a locking plate which fixes the oscillating links, an actuating lever which is connected to one of the oscillating link, and a slide cam which starts moving toward the opening portion in conjunction with an oscillation of the actuating lever.

Description

technical field [0001] This application relates to an optical disc drive for erasing and writing data on a disc-shaped carrier (disc recording tool) such as a compact disc (CD), and more particularly to an optical disc drive capable of reading and / or writing two types of discs with different diameters. Optical drives for large and small disc-shaped carriers. Background technique [0002] In recent years, disc-shaped carriers such as CD, DVD, etc. have been widely used as a recording tool for sound and screen images. Most CDs and DVDs have a diameter of 12 cm (large-diameter discs), but there is also a disc with a diameter of 8 cm. shape carrier, which is referred to as single CD (Compact Disc). These two kinds of large and small discs can be driven by a device, but, in addition to the device where the disc is manually placed on the turntable, it is necessary to pass the two kinds of large and small disc carriers by means of transport rollers. The transport system is precis...
