[Prior art]

  In the optical disk drive device, the information recording track of the optical disk rotating at high speed is The light beam emitted from the optical pickup as a minute spot. Information is recorded and erased by scanning and scanning. Also, the optical disc When playing back the information recorded on the Information is read by irradiating the recording track with a light beam and receiving the reflected light. Will be issued.

[0003]   Normally, in order to load an optical disk into the optical disk drive, pull it from the housing. It is necessary to position and place the optical disc at the prescribed position on the disc tray that was ejected. There is. An optical disc drive device with a turntable integrated into the disc tray In this case, the optical disk is set directly on the turntable, so It is not necessary to provide positioning means on the tray. However, on the disc tray For optical disk drive devices that do not have a turntable integrated, It is necessary to provide some positioning means on the placement surface of the scray. Normal, A recess provided in the disc tray is used as the positioning means.

[0004]   Generally, an optical disc has a large diameter disc with an outer diameter of 12 cm and an outer diameter of 8 cm. There is a small diameter disc. The turntable is integrated with the disc tray. There is no optical disk drive, both large and small diameter disks. In order to make the optical disk drive device compatible with It is necessary to provide a concave portion with a shape corresponding to each disc on the mounting surface of the disc tray. is there. The method of providing the recess is roughly classified into the following two structures.

[0005]   First, the first structure is a structure in which an adapter can be attached to the disc tray. (See, for example, Patent Document 1). With this structure, the disc tray has a large diameter disc. For mounting a small diameter disc on the adapter by providing a first recess for mounting A second recess is provided. Then, load the small diameter disc into the optical disc drive device. In this case, attach the adapter to the disc tray, and then insert the second recess in the adapter. Position and place the small diameter disc. This allows small diameter discs to It becomes possible to set it on the tray. Also, when loading a large diameter disc , Remove the adapter from the disc tray and insert a large diameter directly into the first recess of the disc tray. Position and place the disc. From the above, the large diameter disc and the small diameter disc An optical disk drive device compatible with both can be provided.

[0006]   Next, the second structure is to mount a large diameter disc on the disc tray without using an adapter. A structure in which both a first concave portion capable of mounting and a second concave portion capable of mounting a small-diameter disk are provided. Is. In this structure, the second recess is provided on the bottom surface of the first recess. And large diameter di When loading the disc into the optical disc drive, insert a large diameter disc into the first recess. When directly positioning and placing the small-diameter disc in the optical disc drive, In this case, the small diameter disc is directly positioned and placed in the second recess. Due to the above, Use an optical disk drive that supports both large-diameter disks and small-diameter disks You can

[0007]   In the above-mentioned first structure, it is necessary to separately attach the adapter to the disc tray. This compels the user to perform very troublesome work. For this reason, usually In many cases, the structure of 2 is adopted. The second structure did not require an adapter Therefore, the convenience for the user is significantly improved.

[0008]   FIG. 1 is a schematic perspective view of a conventional optical disk drive device adopting the above-mentioned second structure. 9 shows. As shown in FIG. 9, the disk drawn out from the front opening 11 of the housing 10 is A first recess 31 for mounting a large-diameter disc is provided at a predetermined position on the tray 30.
