Claims

[Scope of Claim for Utility Model Registration] 1. An opening for inserting and ejecting a disk or a cassette containing a disk (hereinafter referred to as a cassette) of an optical or magneto-optical disk recording/reproducing device (hereinafter referred to as the device) is rotated toward the front. A dust-proof lid device that opens and closes an opening that is biased closed by a spring force and covers the periphery of the opening, and the lid device is equipped with a roller rotatable around the longitudinal direction of the lid inside the lid of the lid device. Then, position the roller, the lid, and the cassette insertion/ejection port so that when the cassette is ejected from the device, the roller and cassette contact and slide during the full opening stroke or part of the opening stroke of the lid. A dustproof lid opening/closing mechanism characterized by the provision of. 2. In the apparatus of claim 1, the roller is provided with a hemispherical or arcuate planar member or shape formed integrally with or separately from the lid, and the member or shape is connected to the front or lower surface of the cassette to be discharged. During the ejection operation of the lid, contact and slide during the entire stroke or a part of the stroke, and when the cassette is initially ejected, the lid is brought into contact within a range of 1/2 or more of the thickness of the front surface of the cassette or more far from the center of the opening axis of the lid. The opening/closing mechanism of the dustproof lid is characterized by the ability to 3. In the device according to claim 1 or 2, a wall substantially perpendicular to the ejection direction of the cassette is provided at the center or both ends of the free end of the lid on the opposite side of the rotation axis, so that when the cassette is ejected, the front surface of the cassette is An opening/closing mechanism for a dustproof lid, characterized in that the dustproof lid comes into contact with the wall, and the wall regulates the amount of cassette discharged. 4. In the device of Claims 1, 2, or 3, the corner formed by the tip surface of the free end opposite to the rotation axis of the lid and the surface on the side that closes the cassette insertion/ejection port, or the upper front end of the front panel. A slope or a radius or a concavity that can be engaged with the tip of the cassette over the width of the cassette is provided at the corner, and the angle of the slope and the size of the radius or concavity are determined by holding the cassette with one hand at the corner of the tip and the front surface. A dust-proof lid characterized in that the tip of the cassette is brought into contact with the slope or the surface formed by the radius or the recess, the lid is moved in the opening direction, the lid is opened, and the cassette is inserted into the device with a part of the cassette left behind. opening/closing mechanism. 5. In the apparatus of claim 4, when a part of the cassette is inserted into the apparatus, the insertion of the cassette operates a switch so that the cassette can be positioned on the recording/reproducing means by a power source such as a motor. A dustproof lid opening/closing mechanism characterized by: 6. In an optical or optical disk recording/reproducing device, a cassette insertion/ejection mechanism having a function of positioning a disk or a cassette containing a disk on the recording/reproducing means and a function of ejecting the disk or cassette from the device, and a motor for rotating the disk. An optical pickup drive mechanism, in which an optical pickup is mounted and transported at any position in the radial direction of the disk, is disposed in a case provided with a lid A that opens and closes a disk or cassette insertion/ejection port, and a viscoelastic The case and the lid A are supported by a member or an elastic member.
The front panel, which is located on the front of the case and has a similar opening, is in contact with the entire circumference of the cassette insertion/ejection port of the case, and the opening is further sealed with a spring, and the opening is rotated toward the front to close the opening. Another second lid B that opens, and the front panel, the surface of the tip of the free end opposite to the rotation axis of the lid B, and the corner or front panel that is the surface of the side that closes the cassette insertion/ejection port. At the upper front corner of the cassette, a slope or radius or a recess into which the tip of the cassette can be engaged is provided over the width of the cassette. The dust-proof lid is characterized in that the tip of the dust-proof lid is brought into contact with the sloped or rounded surface or concave portion and moved in the opening direction of the lid B to open the lid B, and the cassette is inserted into the device. Opening/closing mechanism. 7. An opening/closing mechanism for a dustproof lid, characterized in that the viscoelastic member is subjected to quinoid vulcanization (vulcanization using P-quinone dioxime) or secondary vulcanization in the apparatus according to claim 6.
