Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical disk loading device provided in an optical disk reproducing device.

[0002]

2. Description of the Related Art Conventional optical disk drives (optical disk reproducing apparatuses) are classified into a tray type and a slot-in type according to an optical disk loading method.

[0003]

The conventional optical disk drive has the following problems. In the tray type optical disk drive, even if the eject button is pressed when loading or unloading the optical disk, it is necessary to wait for a while until the tray drive mechanism is activated and the tray is actually ejected. Further, even after loading or removing the optical disk from the tray, it is necessary to press the eject button and wait until the tray actually fits. Therefore, it has been difficult to quickly load or unload an optical disk.

In the slot-in type optical disk drive, the optical disk stops when the optical disk is ejected, about halfway out of the unstable slot, so that the periphery of the optical disk must be trimmed to prevent fingerprints and scratches on the optical disk. If you try to pick it up, it becomes unstable. Therefore, there is a high possibility that the optical disk will be lost, and it is easy to damage the optical disk by dropping it on the floor. Also, with a slot-in type optical disk drive, it is not easy to remove the optical disk drive if a failure occurs during operation.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide an optical disk loading apparatus capable of loading and unloading an optical disk quickly and having little risk of erroneously failing to remove the optical disk at the time of discharging. And

As means for solving the above-mentioned problems, an optical disk loading apparatus having the following configuration is employed. That is, the optical disk loading device according to claim 1 is supported so as to be able to protrude and retract from the operation surface of the optical disk reproducing device, the optical disk is placed in a state protruding from the operation surface, and the optical disk is pulled in from the operation surface to load the optical disk. A tray arranged at a predetermined position in the optical disc reproducing device, a driving means for moving the tray up and down from the operation surface, and an opening which is located on the tray and opened on the operation surface and through which the optical disc can be taken in and out; And a transporting means provided continuously to the opening and transporting the optical disk inserted through the opening to the predetermined position.

In this loading device, when loading an optical disk into the optical disk reproducing device, when the optical disk is inserted through the opening, the optical disk is transported to a predetermined position in the optical disk reproducing device by the transport means, and is gripped by the reproducing drive mechanism. It will be ready for playback. When the optical disc is ejected from the optical disc reproducing apparatus, the optical disc is returned from a reproducible state to a predetermined position on the tray, and is ejected out of the optical disc reproducing apparatus by a projecting operation of the tray. As a result, the optical disk can be quickly loaded, and the risk of the optical disk being lost during ejection can be avoided.

According to a second aspect of the present invention, there is provided an optical disk loading apparatus for detecting whether or not the optical disk is placed on the tray. Control means for controlling the operation of the driving means based on the detection result of the means.

In this loading apparatus, when the optical disk detecting means detects that the optical disk is not placed on the tray while the tray is in a state of protruding from the optical disk reproducing apparatus, the control means controls the drive. The means is activated and the tray is automatically retracted. Thereby, a series of operations required for ejecting the optical disk, such as pressing the eject button, is simplified as compared with the conventional case.

According to a third aspect of the present invention, in the optical disk loading apparatus according to the first or second aspect, the tray is protruded from the operation surface regardless of the operation of the driving means, and the optical disk can be taken out. And a take-out means.

In this loading device, even when the optical disk reproducing device goes down due to a system abnormality or the driving device malfunctions, the tray is forcibly protruded regardless of the operation of the driving device, so that the loading of the optical disk is prevented. Extraction becomes possible.
