The fitting hole 54 of the second rotary lever 53 on which the fixing protrusion 67 of the is inserted is rotated counterclockwise. In addition, as the fitting hole 54 of the second rotary lever 53 is rotated counterclockwise, the second rotary lever 53 rotates counterclockwise with respect to the hinge 57 so that the second rotary lever 53 rotates. The second pressing plate 55 attached to one end of the) is rotated into the deck 90 while facing the first pressing plate 64 of the first rotary lever 63.

As described above, the first pressing plate 64 of the first rotating lever 3 is drawn into the deck 90 and the second pressing plate 55 of the second rotating lever 53 is drawn into the deck 90. As a result, the entry range of the 80 mm disk 140 is narrowed.

In addition, when the 80 mm disc 130 enters the deck 90 by the rotary roller 80 while the first and second rotary levers 63 and 53 are rotated, the 80 mm disc 130 is first and second. The side parts are brought into contact with the first and second pressing plates 64 and 55 of the second rotation levers 63 and 53 and are positioned on the turntable 120 of the deck 90.

At this time, since the 80mm disk 140 enters along the first and second pressing plates 64 and 55 of the first and second rotation levers 63 and 53, the disk entry range is limited in advance so that the 80mm disk 140 The entry of is very accurate and stable.

On the other hand, when the 80 mm disk 140 is completely loaded onto the deck 90, as shown in FIG. 6 (b), the first LED 71 and the second LED 72 of the disk entry detecting member 70 are shown. Since both are turned on to determine the loading completion state of the 80mm disk 140, the 80mm disk 140 is chucked and driven on the turntable 120.

And when the loading of the replacement 80mm disk 140 to 120mm disk 130 as described above will be described as follows.

First, the 80mm disk 140 is pulled out, and then the operation lever 21 that is pressed is pulled out to release the fixing protrusion 46 of the clutch arm 40 from the recess 24 of the operation lever 21. At this time, the actuating lever 21 is moved to the outside while the pressing spring 25, which is inserted into the fixing protrusion 46 of the clutch arm 40, is compressed. As described above, as the fixing protrusion 46 of the clutch arm 40 is separated from the recess 24 of the operating lever 21, the clutch arm 40 rotates clockwise about the rotation shaft 41 to allow the clutch to rotate. The fitting protrusion 43 of the arm 40 is fitted to the fixing hole 66 formed in the fixing plate 60 of the deck 90.

When the 120 mm disk 130 is inserted into the deck 90, the first pressing plate 64 of the first rotating lever 63 and the second pressing plate 53 of the second rotating lever 53 are connected to the 120 mm disk ( Contacting the outer circumferential surface of 430 to overcome the elastic force of the first elastic spring 65 and the second elastic spring 56 by the input force of the 120 mm disk 130 and the first rotation lever 63 in the counterclockwise direction. The second rotary lever 53 rotates clockwise.

As described above, the first rotary lever 63 rotates counterclockwise and protrudes into the fixing hole 66 of the fixing plate 60 by the elastic force of the spring 44 installed on the support 40 of the clutch arm 40. The fitting protrusion 43 of the clutch arm 40 is fitted into the fixing hole 66 of the first rotating lever 63 to prevent rotation of the first rotating lever 63.

As the rotation of the first rotation lever 63 is prevented as described above, the rotation of the second rotation lever 53 having the fitting hole 54 in which the fixing protrusion 67 of the first rotation lever 63 is fitted is prevented. do.

The outer circumferential surface of the 120 mm disk 130 contacts the first pressing plate 64 of the first rotating lever 63 and the second pressing plate 55 of the second rotating lever 53, which are thus fixed, into the deck 90. The 120mm disk 130 is entered while pushing the guide plate 110 to the rear surface with respect to the guide hole 101 of the clamp chassis 100.

On the other hand, when the 120 mm disk 130 is completely loaded on the deck 90, the first LED 71 of the disk entry detecting member 70 is turned off and the second LED 72 is turned on, so that the 120 mm disk 130 is The loading completion state is determined and the 120 mm disk 130 is chucked to the turntable 120 to be driven.

Therefore, the conventional clamping device chucks the disk by misleading the LED when the centering state of the disk is not completed correctly when the 80 mm disk enters the disk guide device according to the present invention, unlike the problem that the disk is broken or damaged. When used, the 80mm disc and the 120mm disc along the first and second press plates of the first and second rotary levers are rotated by appropriately rotating the first and second rotary levers by pressing the operating lever to rotate the clutch arm when the 80mm disc is inserted. By guiding, the disk must be centered on the turntable so that the disk is placed on the turntable as long as the disk is chucked, thereby effectively preventing the disk from being broken or broken.
