Each guide member 22 is further provided with a guide pin 225 protruding upward.

The guide member driving means is for moving each of the guide members 22 and includes a slider 60 and the motor 14.

The slider 60 has a guide hole 601 formed long in the disc insertion direction A. As shown in FIG. The slider 60 is slidably fitted in the guide slot 601 and is fixed to the cover 20 by a guide pin 602 to slidably slide in the disc insertion direction A and vice versa. ) Is combined. The slider 60 is also provided with first cam portions 61, second cam portions 62, cam portions 64 for guide members, and engaging projections 605.

Each of the first cam portions 61 is slidably restrained by first guide pins 415 supported by the first pivot members 41 by screws 414. Each first cam portion 61 has an inclined portion 611 inclined with respect to the disc insertion direction (A).

Each of the guide member cams 64 has an inclined portion 641 inclined with respect to the disc insertion direction A so that the guide pins 225 of the guide members 22 can be moved while the slider 60 is sliding. )

The coupling protrusion 605 is slidably fitted into the guide slot 201 of the cover 20 to be coupled to the coupling hole 151 of the rack 15. Thus, when the rack 15 is reciprocated by the motor 14, the slider 60 is reciprocally slid with the rack 15 in the disc insertion direction A and vice versa.

In the disc player having such a disc guide device, when the disc 1 is inserted through the disc inlet 31 of the front panel 30 as shown in FIG. 3, the insertion direction of the disc 1 ( The outer circumferential surface of the front end portion of A) is in contact with the first contact members 40. At this time, the guide members 22 are close to each other as shown in FIG.

When the force in the insertion direction A is continuously applied to the disk 1 in the state shown in FIG. 3, the force in the direction spaced apart from each other by the disk 1 is transmitted to the first contact members 40. . By this force, the first pivot members 41 are hinged shafts until the first contact members 40 are spaced apart from each other and positioned in a position that does not interfere with the insertion of the disk 1, as shown in FIG. 411 is rotated around the center. As such, the spring 49 is tensioned and has a restoring force while the first pivot members 41 are rotated. When the disk 1 is slightly inserted in this state, the first pivot members 41 rotate in the direction in which the first contact members 40 approach each other by the restoring force of the spring 49. Accordingly, the first contact members 40 press the outer peripheral surface of the rear end in the insertion direction A of the disk and transfer the disk 1 to the predetermined position as shown in FIG. 6.

In order to reproduce the information of the disc 1, the disc 1 is loaded from the position shown in FIG. 6 to the position clamped by the turntable 13 and the chuck 21. When the disk is loaded, the rack 15 is moved to the disk insertion direction A by the motor 14 (see FIG. 1), and the engaging protrusion 605 coupled to the engaging hole 151 of the rack 15 is provided. And the slider 60 to which the engaging projection 605 is fixed slide as shown in FIG. 7 along the disc insertion direction A. As shown in FIG. As the slider 60 slides as described above, the first guide pins 415 restrained by the first cam portion 61 of the slider 60 are mutually approached by the inclined portion 611 of the first cam portion 61. The first pivotal members 41 are rotated in a direction approaching each other about the hinge shaft 411 while being moved in a direction in which the pivoting direction is performed. Accordingly, the first contact members 40 are also moved in the mutually approaching direction to press the rear end of the disk 1 and to press the disk 1 as shown in FIG. 7, the center of which is the center of the chuck 21. It will be loaded into the clamping position coincident with the center. As such, while the disc 1 is loaded to the second position by the first contact members 40, the second guide pin 515 is moved by the inclined portion 421 of the second cam portion 42. By rotating the second pivot member 51 about the hinge shaft 511 while moving, the second contact member 50 fixed to the second pivot member 51 is moved in a direction away from the disk. Therefore, the second contact member 50 does not interfere with the loading of the disk 1 while the disk 1 is loaded to the second position by the first contact members 40.

On the other hand, in the process of loading the disk 1 from the position shown in FIG. 6 to the position shown in FIG. 7, both edges of the disk 1 are guide slots 222 of the guide members 22, respectively (see FIG. 4). The disk 1 is loaded into the above-described clamping position while sliding with respect to the guide member 22 in a state where up and down flow is suppressed by the guide member 22.

After the disk 1 is loaded into the clamping position, the slider 60 continues to slide in the disc insertion direction A to the position as shown in FIG. 8 by the motor 14.

As described above, in the process of moving the slider 60 from the position where the loading of the disk 1 is completed as shown in FIG. 7 to the position as shown in FIG. 8, the cam part 64 for the guide member of the slider 60 is shown. The guide pins 225 constrained to the field are moved by the inclined portion 641 of the cam portion 64 for the guide member, so that the guide members 22 are moved in the direction away from each other. Accordingly, the disk 1, whose both edges are inserted into and supported by the guide slots of the guide members 22, is released from the guide members 22 as shown in FIG. As a result, the disk is in a state capable of being moved in the vertical direction.

As described above, at substantially the same time as the guide members are spaced apart from each other, the first guide pins 415 are moved by the auxiliary inclined portion 612 of the first cam portion 61 in the opposite direction as in the loading process. The second guide pin 515 is moved by the auxiliary inclined portion 622 of the second cam portion 62 in the same direction as in the loading process. Accordingly, the first contact members 40 and the second contact member 50 are spaced apart from the disk 1 while the first pivot members 41 and the second pivot members 51 are rotated.

Then, in the state as shown in FIG. 8, when the deck 11 (see FIG. 1) is rotated about the hinge point 111 so that the turntable 13 is raised by an appropriate lifting means, it is shown in FIG. 9. As described above, the loaded disk 1 is slightly lifted upward by the turntable 13 and the chuck 21 is moved by the magnetic force of the magnet 131 fixed to the turntable 13 of the disk 1. While contacting the upper surface, the disk 1 is clamped to the turntable 13 by clamping the disk 1 together with the turntable 13. The clamped disk 1 is rotated together with the spindle motor and the chuck by the rotation of the spindle motor 12 (see FIG. 1), and the information of the disk 1 is read by the optical pickup 135.

As described above, while the disk 1 is loaded, the guide members 22 are guided by inserting both edges of the disk 1 to be approached and loaded, and the guide members 22 are spaced apart from each other after the loading is completed. When the interference with the loaded disc 1 is configured to be canceled, the disc can be prevented from flowing up and down while the disc is being loaded. Thus, noise and clamping defects caused by the up and down flow of the disc during loading as described above are eliminated. Suppressed.

In the present embodiment, the guide rail 26 for guiding the insertion of the disc into the disc player body is manufactured separately from the guide member 22 for guiding the loading of the disc inserted into the disc player body and fixed to the disc player body. It is described and illustrated as. However, the guide rail 26 is deleted and the guide member 22 is extended to the position where the guide rail is installed so that the disc is guided by the extended guide member even while the disc is inserted into the disc player body. It can also be configured.

In addition, it has been described that the disk is applied to the disk player of the structure loaded by the contact members 40 and 50 in contact with the outer peripheral surface of the disk, for example, a pair of rollers are in contact with both sides of the disk, respectively, to rotate Of course, the present invention can also be applied to a disc player or the like configured to load the disc.

In addition, the shape of the guide member cam portion 64 formed on the slider 60 is not limited to the illustrated state, and may be changed as long as it does not depart from the spirit of the present invention according to the sliding direction of the slider. .

As described above, the disc guide device of the disc player according to the present invention, the guide member is approached to each other during the loading of the disc guided by inserting the edges of both sides of the disc, and after the loading is completed, the guide members are spaced apart from each other to interfere with the disc. Since the disk is configured to be canceled, the disk is prevented from flowing up and down during the loading of the disk, thereby suppressing the noise or the clamping defect due to the vertical flow of the disk during the loading of the disk.
