1 is an exploded perspective view showing a schematic configuration of an optical disk drive, FIG. 2A is an exploded perspective view showing the configuration of the turntable shown in FIG. 1, FIG. 2B is a sectional view of the turntable shown in FIG. 2A, and FIG. 3. Is a view showing the 80mm optical disk mounted on the second mounting surface when the optical disk drive is installed vertically, Figure 4 is a view showing the 80mm optical disk is spread across the tray in FIG.

1, 3, and 4, the optical disc drive 100 includes a main frame 110, a tray 120 for mounting an optical disc and entering and exiting the main frame 110, and the main frame 110. It is provided with a case 150 is installed on the upper side of the clamp 150 to fix the optical disk to the turntable.

The tray 120 includes a first mounting portion 121 on which an optical disk D1 having a diameter of 120 mm is mounted, and a second mounting portion 122 on which an optical disk D2 having a diameter of 80 mm (see FIG. 3) is mounted. The first mounting portion 121 is formed to be recessed downward from the upper surface of the tray 120, so that the optical disk D1 may be mounted. The second mounting portion 122 is formed to be recessed downward from the top surface of the first mounting portion 121, so that the optical disk D2 may be mounted.

In the drawing, a first mounting portion 121 on which a 120 mm optical disk is mounted and a second mounting portion 122 on which an 80 mm optical disk is mounted are formed in the tray 120, but are not necessarily limited thereto and are larger in diameter than the 80 mm optical disk. Other mountings may be provided which can also be mounted with small optical discs.

Four protrusions 123 are provided at the edge of the first mounting portion 121 to protrude to prevent the 120mm optical disk D1 from being separated from the first mounting portion 121.

At the edge of the second mounting portion 122, a plurality of first separation preventing portions 125 are provided to prevent the 80 mm optical disc D2 from being separated from the second mounting portion 122. The first departure preventing part 125 is preferably configured to be provided with at least one on each side when the second mounting portion 122 is divided into four quadrants. 3 and 4, when the tray 120 is vertically used, the first departure preventing part 125 is preferably positioned at the upper and lower sides of the second mounting part 122. Do. This is because the 80mm optical disc D2 is separated from the upper or lower side of the second mounting portion 122 when the 80mm optical disk D2 is separated from the second mounting portion 122.

The first detachment preventing part 125 is provided at a lower position than the first mounting part 121 and is formed to protrude to the inside of the second mounting part 122. This is to prevent the information area from being damaged by preventing the first escape preventing part 125 from coming into contact with the information area of the 120 mm optical disc D1.

Four second detachment prevention parts 124 protruding upward are provided at the edge of the first mounting part 121. The second departure preventing portion 124 is formed adjacent to the four projections 123, respectively, and as shown in FIGS. 3 and 4 when the tray 120 is used in the vertical direction It is preferable that the 80 mm optical disc D2 is held so as to be separated from the two mounting portions 122 but not to be separated from the tray 120. Therefore, the second departure prevention part 124 is preferably provided to be located on the upper and lower side of the first mounting portion 121 when the tray 120 is used vertically.

The main chassis 110 is provided with a sub chassis 130 to be rotatable in the vertical direction. When the sliding member 112 is slid by the driving device 111 in the perpendicular direction (Y direction) of the direction in which the tray 120 enters and exits the main frame 110, the sub chassis 130 is vertically moved. It is rotated in the (Z direction).

The subchassis 130 supports one side of the main base 131. The main base 131 has a turntable 140 on which an optical disk is seated, and an optical pickup 132 for recording information on or reproducing the recorded information while sliding in the radial direction of the optical disk seated on the turntable 140. ) Is installed.

 One side of the main base 131 is supported by the sub chassis 130, and the other side of the main base 131 is supported by the main frame 110. Therefore, when the subchassis 130 is rotated in the vertical direction (Z direction), one side of the main base 131 also moves in the vertical direction together with the subchassis 130, so that the turntable 140 is optical. The disk can be accessed or spaced apart.

2A and 2B, the turntable 140 includes a seating surface 145 on which an optical disk is mounted on an upper portion of the body 141, and protrudes from an upper portion of the body 141. A fixing part 142 having a groove 143 formed therein, and a plurality of fixing jaw 144 having its own elastic force in a cantilever shape connected to one side of the groove 143 and connected to the fixing part 142. The plurality of fixing jaw 144 is provided with an elastic portion 146 that can add an elastic force, respectively.

The elastic portion 146 has a cylindrical body 147 and a plurality of elastic bodies 148 formed at equal intervals to protrude upward from the body 147 to correspond to the plurality of fixing jaws 144, respectively. Equipped.

When the elastic portion 146 is inserted into the body 147, the plurality of elastic bodies 148 are positioned behind the plurality of fixing jaws 144, as shown in FIG. 2B. Therefore, since the plurality of elastic bodies 148 apply an elastic force to the plurality of fixing jaws 144, the plurality of fixing jaws 144 may hold the optical disk as a stronger elastic force. Therefore, even when the tray 120 is installed upright, the 80 mm optical disc is separated from the second mounting portion 122 due to the elastic force applied to the plurality of fixing jaws 144 by the elastic portion 146. Can be prevented.

In the optical disk D1, a through hole 200 formed in the center thereof (see FIG. 1) is fitted into the fixing part 142, and the plurality of fixing jaws 144 and the plurality of elastic parts 146 are 120 mm and the like. Since the 80 mm optical disk D1 is elastically applied in the radial direction thereof, the optical disk D1 may be fixed to the turntable 140.

A hole 151 is formed in the case 150, and the clamper 160 is mounted in the hole 151. The hole 151 is covered by the cover 170.

In addition, by reducing the thickness of the clamper 160 mounted in the hole 151, the clamper 160 is in close contact with the turntable 140, thereby between the clamper 160 and the turntable 140 The optical disc installed in the clamp can be clamped more firmly. By doing so, even when the tray 120 is used vertically, the clamper 160 and the turntable 140 firmly fix the 80 mm optical disk, thereby preventing the 80 mm optical disk from being separated from the second mounting portion 122. can do.
