Problems solved by technology

However, in this structure, it is difficult to separate the positioning member sufficiently from the outer peripheral edge of the disc.
Especially in thin optical disc devices, since the rotation angle of the clamping arm is small when clamping the optical disc, the positioning member cannot be sufficiently separated from the outer peripheral edge of the optical disc

Embodiment Construction

[0028] figure 1 The illustrated optical disc device can read information from and / or record information on an optical disc having a diameter of 8 cm or 12 cm, such as a compact disc (CD) or a digital versatile disc (DVD). A disc with a diameter of 8 cm is called a small-diameter disc Ds, and a disc with a diameter of 12 cm is called a large-diameter disc D.

[0029] A protruding portion 2a on which a liquid crystal display and various switches are mounted is placed at the front surface of the housing 2, which forms a figure 1 The external shape of the optical disc device 1 is shown. A long and narrow insertion opening 3 extending in the width direction (X direction) is formed in the protruding portion 2a.

[0030] The base 6 is placed inside the housing 2 . A rotation drive section (disc drive section) 4 and a clamper 5 are mounted on the chassis 6 . The rotary driving part 4 is arranged below the passage for inserting the optical disc D, and the clamper 5 is arranged abov...

Abstract

A disc device including a disc driving section, a transport roller, a positioning member, a detection section, a transmitting member for transmitting movement of the detection section to the positioning member, a roller supporting member for moving the transport roller to a transport position where the transport roller is capable of transporting a disc and to a retreat position where the transport roller is separated from the disc, and a restraining section disposed at the roller supporting member. When the transport roller moves to the retreat position, the detection section is restrained by being moved in a predetermined direction by the restraining section and the movement of the detection section when restraining the detection section is transmitted to the positioning member through the transmitting member, so that the positioning member moves so as to separate from the outer peripheral edge of the disc.

Description

technical field [0001] The present invention relates to an optical disk device in which an optical disk such as a compact disk (CD) or a digital versatile disk (DVD) is conveyed by conveying rollers and positioned in a disk driving section. More particularly, the present invention relates to an optical disc device capable of avoiding interference of a disc positioning member with respect to the rotation of a driven disc. Background technique [0002] In an optical disc device in which information is recorded onto and reproduced from the optical disc by automatically pushing the disc into the disc device, the inserted disc must be reliably positioned on the turntable of the disc drive section. In an optical disc device that can receive, for example, a small-diameter optical disc with a diameter of 8 cm and a large-diameter optical disc with a diameter of 12 cm, it is necessary to position these optical discs on the same turntable. [0003] Therefore, in these related optical...
