Abstract
A disc-conveying structure of slot-in optical disc device, mainly an optical disc device for optical disc, includes a switch device, cooperating with the action of the optical disc to start or close the procedure of disc-conveying; a roller device, which is a cylindrical roller pivotally connected to a main chassis of the optical disc device and formed as conveying device with driving of a motor; and a clamping device, which is a caging mechanism for optical disc and enables the optical disc to be conveyed to the correct working area so as to be accessed successfully by the disc read/write head.
Claims14
A disc-conveying structure of slot-in disc device, mainly an optical disc device for optical disc, comprising:
- a switch device cooperating with the disc-conveying action to selectively start and close the procedure of disc-conveying;
- a roller device consisting of a cylindrical roller pivotally connected to a main chassis of the disc device, formed as a conveying device with driving of a motor;
- and
- a clamping device including a holding lever and a locking mechanism, wherein the holding lever is constituted of a first lever arm and a second lever arm, each of which are disposed on the main chassis in relative locations, and the locking mechanism is driven by different dimensions of discs to control the degree of the motion range of the first lever arm and the second lever arm so as to selectively form a corresponding minimum included angle and a maximum included angle, and with a coupled mechanism between the first lever arm and the second lever arm, the first lever arm and the second lever arm make relative gyratory motions synchronously.
A disc-conveying structure of slot-in disc device, mainly an optical disc device for optical disc, at least comprising:
- a switch device including a lock gate mechanism and a limit switch respectively disposed on the loading slot of the main chassis of the optical disc device, the lock gate mechanism being expanded by the insertion of the optical disc, the limit switch set up at a certain position in the expanding path of the lock gate mechanism, with the selectively expanding and drawing back of the lock gate mechanism to trigger the limit switch, the roller device selectively starting and closing the disc-conveying procedure.
- a clamping device being as a caging mechanism for the optical disc to restrict the optical disc to be put in the correct working area A1 such that the optical disc is able to be accessed successfully by the disc read/write head.
