Description

The present invention relates to an optical disk device, and more particularly, to a blue-violet optical disk device that detects insertion of a disk by an optical sensor.

Among conventional optical disk apparatuses, in particular, an optical disk apparatus of a slot-in type blue-violet disk (registered trademark name: Blu-ray Disc) includes a mounting mechanism 1, a traverse 2 and a slide mechanism 3, as shown in FIG. Have. An insertion port is provided at the front end of the mounting mechanism 1. The traverse 2 is arranged in the mounting mechanism 1 and reads a disk. The slide mechanism 3 is disposed in the mounting mechanism 1 and reciprocates along a predetermined path to carry the disc to a position where the traverse 2 can read the disc, or carry the disc to a position where the user can take out the disc. To do.

The slide mechanism 3 includes a slide base 4, two clamping pieces 5, and a driving device 6. The sandwiching piece 5 is disposed on the slide table 4. The drive device 6 is used to move the slide table 4 in the mounting mechanism 1. The driving device 6 is electrically connected to an elastic switch 8 disposed on the slide table 4 via a control circuit board 7. When the slide base 4 is located at the disk take-in position and the user inserts the disk 9 into the insertion slot, the disk 9 is sandwiched between the slide base 4 and the sandwiching piece 5 as shown in FIG. Further, when the disk 9 contacts the elastic switch 8, the elastic switch 8 transmits a contact signal to the control circuit board 7. As a result, the control circuit board 7 drives the driving device 6 to simultaneously move the slide table 4, the holding piece 5 and the disk 9 to the disk reading position. Next, a disk reading operation is performed by the traverse 2.

However, the structure in which the drive device 6 is controlled using the contact type elastic switch 8 is such that the position of the elastic switch 8 shifts or falls off the slide table 4 as the slide table 4 moves. A situation in which 9 cannot be taken in (the operation of the driving device cannot be controlled) is likely to occur. Alternatively, when the disk 9 is used for a long time, the elastic switch 8 is brought into elastic fatigue due to contact with the elastic switch 8 several times, and a situation occurs in which the take-in time of the disk 9 is delayed.
