In the disc player having such a disc housing device, when the disc 1 is inserted through the disc inlet 31 of the front panel 30, as shown in FIG. The outer peripheral surface of the delivery part of A) is brought into contact with the first contact members 40 as shown in FIG. In this state, if the force in the insertion direction A is continuously applied to the disc 1, the force in the direction spaced apart from each other by the disc 1 is transmitted to the first contact members 40. By this force, the pivot members 41 are hinged until the first contact members 40 are spaced apart from each other and positioned in a sitting position not interfering with the insertion of the disk 1, as shown in FIG. 411 is rotated around the center. As such, while the rotating members 41 are rotated, the spring 49 is tensioned and has a restoring force. When the disk 1 is slightly inserted in this state, the rotating members 41 rotate in the direction in which the first contact members 40 approach each other by the restoring force of the tensioned spring 49. Accordingly, the first contact members 40 fixed to the pivot members 41 press the outer peripheral surface of the rear end portion of the disk insertion direction A while the disk 1 is shown in FIGS. 8 and 9. It is inserted into a predetermined first position as shown. At this time, both edge portions of the disc 1 to be inserted are slidably fitted to the guide rails 26 so that the insertion movement thereof is guided. In the state where the disk 1 is inserted in the first position, the first contact member 40 is elastically in close contact with the rear end of the disk 1 by the spring 49 and the second contact member 50 is connected to the front end. By being elastically in close contact, the disk 1 is supported in a state that is elastically housed in its first position.

Meanwhile, the disk 1 supported at the first position may be loaded to a position clamped by the turntable 13 and the chuck 21 through the power of the motor 14. This disk loading process will be described briefly.

First, as shown in FIGS. 8 and 9, when the disk 1 is held in the first position, the first pinion is rotated counterclockwise in the drawing by the motor 14, The second pinion 147 geared to the first pinion 145 through the connecting gear 148 also rotates in the same direction as the first pinion 145, that is, counterclockwise in the drawing. Accordingly, the pressing member 16 geared to the second pinion 147 moves in the disc insertion direction (A). Then, when the pressing member 16 is moved, the engaging projection located at the very front in the disc insertion direction presses the stopper portion 154 of the movable member 15, whereby the movable member 15 is pressed against the pressing member ( 16) together with the disk insertion direction (A). As the rack member 152 of the movable member 15 is geared to the first pinion 145 while the movable member 15 is moved as described above, the movable member 15 is pressed by the first pinion 145. ) Is moved along the disk insertion direction A to the position shown in FIG. As such, while the moving member 15 is moved, the engaging projection 605 coupled to the engaging hole 151 of the moving member 15 and the slider 60 to which the engaging projection 605 is fixed are inserted in the disc insertion direction (A). As shown in FIG. 11, the first guide pins 415 slid along the first cam portion 61 of the slider 60 are approached by the first cam portion 61. Is moved to. In the process of moving the first guide pins 415, the rotation members 41 respectively supporting the first guide pins 415 are rotated in a mutually approaching direction about the hinge axis 411. By rotation, the first contact members 40 are also moved in a direction approaching each other. As shown in FIGS. 10 and 11, the first contact members 40 approaching each other are pressed against the outer peripheral surface of the rear end of the disk 1 and press the disk 1 in the disk insertion direction A. The disk 1 is loaded into a clamping position where the center of the disk 1 coincides with the center of the chuck 21. The disc 1 loaded into the clamping position can be clamped by the chuck 21 and the turntable 13 at that position. Meanwhile, while the disc 1 is loaded to the clamping position by the first contact members 40, the second guide pin 515 is moved by the second cam portion 42 to hinge the lever 51. By rotating around 511, the second contact member 50 fixed to the lever 51 is moved in the direction away from the disk 1. Therefore, the second contact member 50 does not interfere with the loading of the disk 1 while the disk 1 is loaded into the clamping position by the first contact members 40.

When the disc 1 is unloaded, the motor 14 is rotated in reverse to undergo a process opposite to that of the loading process so that the moving member 15, the pressing member 16, and the contact members 40, 50 are again rotated. Moved to a state as shown in FIGS. 8 and 9, the disc 1 is again supported in the first position. The disc 1 supported in the first position may be taken out from the disc player body while spreading the contact members 40 and 50 when the user pulls both sides of the disc by hand, but the disc 1 may be removed. There is a possibility that the user's fingerprint or the like remains on the recording surface, which adversely affects the recording / playback characteristics. According to the present invention, however, the disc 1 positioned in the first position can be taken out of the disc player main body by the disc ejecting means even if the user does not directly grasp the disc. This disc ejection process will be described.

In a state as shown in FIGS. 8 and 9, the motor 14 operates to rotate the first pinion 145 clockwise. Accordingly, the second pinion 147 geared with the first pinion 145 through the connecting gear 148 is rotated in the same direction as the first pinion 145. At this time, since the rack portion 152 of the movable member 15 is disengaged with the first pinion 145 as described above, the movable member 15 is not moved in the position shown in FIG. Only the pressing member 16 geared to the second pinion 147 is moved in the disc ejection direction B while tensioning the tension coil spring 17. In this process, the pressing unit 161 of the pressing member 16 presses the disk 1 to eject the disk 1 from the disk player main body as shown in FIG. The ejected disk can be ejected by the user grasping both edges in the insertion direction of the disk, so that the recording surface of the disk can be effectively prevented from being damaged. Then, the motor 14 again rotates in the direction of loading the disk 1 to rotate the pinions 145 and 147 in the counterclockwise direction to re-move the moving member 15 geared to the second pinion 147 again. Move to the position as shown in 3 degrees.

As described above, according to the present invention, a pair of second contact members 50, which are pressed by the disk 1 inserted into the disc player body and moved in a spaced apart direction, and a second contact contacting the front end of the inserted disk As the member 50 and the first contact member 40 approach each other, the spring 49 provides an elastic force to press the rear end of the inserted disk to elastically contact the disk with the first contact member 40. And a disk is received and supported by a disk ejecting means at a predetermined position in the disk player body and can be ejected from the disk player body. Therefore, when the rotating members 41, the lever 51, the slider 60, etc. are manufactured by using a thin metal plate or are used by thin plastic injection molding, problems in the conventional disk storage device, that is, rollers having a predetermined diameter As these components must be installed side by side in a direction perpendicular to the insertion direction of the disc, it is possible to improve the disadvantage of obtaining a thin disc player. In addition, according to the present invention, since the disc can be inserted and ejected even when the component for inserting the disc 1 does not contact the recording surface of the disc, damage to the recording surface of the disc can be prevented.

In the present embodiment, the first contact members 40 are fixed to the rotation members 41 rotatably installed on the cover 20, and the first contact members 40 are rotated by the rotation members 41. Are illustrated and illustrated as being moved. However, the present invention is not limited thereto, and for example, the first contact members may be fixed to the plate-shaped members provided to be capable of linear reciprocation so that they can be moved by linear movement of the members.

In addition, the movable member 15 is installed to reciprocate in the disc insertion direction (A) and the ejection direction (B), and the loading and unloading of the disc 1 is simultaneously performed by the reciprocating movement of the movable member 15. Embodiments that can be made are described and illustrated. However, the moving member 15 as a component for taking out the disk 1 does not necessarily have to be included as a component for loading and unloading, and the disc player does not include the moving member 15. Of course, it can also be equipped with a loading device.

As described above, the disk receiving apparatus according to the present invention includes the first contact members and the second contact member which are moved in a plane parallel to the disk insertion direction, and the contact members elastically contact the inserted disk. It is provided with a spring for providing an elastic force to support the disk, and a disk ejection means for ejecting the housed disk, it is advantageous in terms of thinning of the disk player and protection of the disk.
