Abstract
An insertion-proof device for optical disk drive is provided to prevent other discs from being inserted in the operating disk drive. A slider moves back and forth along the optical disk drive to load and unload a disc. A push head is disposed on one end of the slider near an entrance. A protrusion is extended backward from the protection unit and disposed on the moving path of the slider. At least one supporting arm is extended from the protection unit. After a disc is loaded, the push head pushes the protrusion, so that the protection unit rotatably fixed near the entrance is turned upward to cover part of the entrance to prevent other discs from being inserted in the operating disk drive. When unloading a disc, the push head releases the protrusion, so that the protection unit leaves the entrance for the original position.
