Description of the Related Art Conventionally, a disk mounting / dismounting apparatus in which a surface of a disk-shaped reproduction recording medium is vertically mounted on a compact disk mechanism or the like in an acoustic reproduction apparatus is disclosed in Japanese Patent Application Laid-Open No. 1-185871. FIG. 6 is an external perspective view of a sound reproducing apparatus using a conventional disk attaching / detaching apparatus, and FIG. 7 is a side sectional view of the same disk attaching / detaching apparatus. In FIGS. 6 and 7, a CD mechanism 4 using a compact disk (hereinafter abbreviated as CD) as a recording medium for reproduction is arranged so as to drive the surface of the CD in a substantially vertical state. The disk clamper 12 is attached to the lid 21 so as to swing and rotate within a certain range so as to face the cover 4a, and the lid 21 is opened (counterclockwise) to the cabinet 5 about the rotation shaft 21e. Is mounted to be openable and closable.
[0003]
The lid 21 is always urged in the lid opening direction by the open spring 15, and in the closed state, the state is held by a lock piece (not shown), and the lid is opened by pressing the eject button 18 . A transition operation is performed. The cover 21 is provided with a disk receiver 16 so that a 12 cm CD 6 can be mounted in an open state, and the clamper 12 has a magnet for adsorbing to the magnetic turntable 4a for holding the CD6 between the turntable 4a. 17, the rotation of the turntable 4a can be efficiently transmitted to the CD6, and the rotation of the turntable 4a causes the disk clamper 12 to rotate integrally with the CD6 without contacting the lid 21. Further, at the time of shifting to the open state, when the lid 21 rotates counterclockwise in FIG. 7 around the rotation shaft 21e, the flange 12a of the disc clamper 12 is formed by the lower rib 21a formed on the lid 21. 7, the disk clamper 12 is released from the attraction force of the magnet 17 to the turntable 4a, and the 12 cm CD 6 held between the disk clamper 12 and the turntable 4a can be taken out.
[0004]
As a means for attaching and detaching the small 8 cm CD 10 shown by oblique lines in the figure, an 8 cm disc receiver 21 b is formed on the lid 21 so that the 8 cm CD 10 can be mounted. When the 8 cm CD 10 is mounted, the tip 21 c of the 8 cm disk receiver 21 b is formed with a certain gap a so as not to come into contact when the 12 cm CD 6 is mounted when the lid is closed. It is necessary to put the lower end of the 8 cm CD 10 on the 8 cm disk receiver 21b. For this reason, a step is formed between the upper rib 21d and the lower rib 21a so that the lower side of the flange 12a is pulled. In such a configuration, since the clamper 12 is attracted to the magnetic turntable 4a by the attracting force of the magnet 17, when the lower side of the flange 12a is pulled, the disc clamper 12 and the 8 cm CD 10 are centered around the point b. At the same time, when rotating simultaneously in the clockwise direction and releasing from the attraction force of the magnet 17, the 8 cm CD 10 fits on the 8 cm disk receiver 21b.

A configuration in which a disc holder for holding the disk.
[0009]
In this configuration, when the disk holder remains below the disk behind the transition of the lid to the open state when the lid transitions from the closed state to the open state, the disk holder is engaged in conjunction with the transition to the open state of the lid. The combining means acts to release the suction to the turntable from below the disk clamper and drop the held disk onto the disk holder.
[0010]
Thereby, the operability at the time of mounting is also improved, and a compact sound reproducing apparatus which is not restricted by design in the arrangement of the rotating shaft of the lid can be obtained.
[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of a disk attaching / detaching apparatus according to the present invention will be described with reference to FIGS. FIG. 1 is a perspective view showing the appearance of a sound reproducing apparatus using a disk loading / unloading apparatus according to an embodiment of the present invention. In FIG. On the other hand, it can be freely opened and closed. The link 3 has a function of a stopper that keeps the opening angle of the lid 1 constant with respect to the main body cabinet 5 and a role of maintaining the strength of the lid 1. It is designed to be stored while rotating inside. The CD mechanism 4 arranges the surface of the CD, which is a recording medium, substantially perpendicular to the main body cabinet 5, and the main body cabinet 5 has a recess 5 a into which a 12 cm CD 6 is inserted, centering on the turntable 4 a of the CD mechanism 4. are doing. A lock claw 1b is formed on the lid 1 and is held by a lock piece 7 in a closed state. The rib 1a formed on the lid 1 receives an urging force in a fixed opening direction on the lid 1 by pressing an open spring 8 fixed to the main body cabinet 5 in a closed state. The eject button 9 and the lock piece 7 are configured to work together. When the eject button 9 is pressed, the lock piece 7 is lowered, the locked state is released, and the lid 1 is opened by a certain angle by the urging force of the open spring 8. And manually open any angle beyond that.
[0012]
FIGS. 2A and 2B are perspective views showing the state of mounting a CD when the lid is opened in the disk attaching / detaching apparatus. FIG. 2A shows a state where a 12 cm CD 6 is mounted, and FIG. 2B shows a state where an 8 cm CD 10 is mounted. In particular, a semicircular disk holder 11 is formed on the outer periphery of the lower edge of the disk clamper 12 to hold the 8 cm CD 10.
[0013]
FIG. 3 is a side sectional view of the disk attaching / detaching device according to one embodiment of the present invention, FIG. 4 is a side sectional view showing a state where the lid is opened, and FIG. FIG. In the main body cabinet 5, a CD mechanism 4 having a turntable 4a is arranged so as to drive the CD surface in a substantially vertical state. The lid 1 is attached so as to be rotatable about a rotation shaft 2 provided below the cabinet 5 in the left opening direction (counterclockwise) in the figure. The disc clamper 12 is held by the cover 1 so as to be swingable and rotatable in a certain range by a clamper holder 13 so as to face the turntable 4a driven by the CD mechanism 4. The disc clamper 12 has a magnet 17 inside, which holds the 12 cm CD 6 or 8 cm CD 10 between the turntable 4 a and the turntable 4 a by an attraction force attracted to the turntable 4 a made of a magnetic material. It rotates integrally with the 12 cm CD 6 or 8 cm CD 10 without touching the 1.
[0014]
An inclined surface 13a is formed on the clamper holder 13 as the engaging means, and when the lid 1 is shifted from the closed state to the open state, the inclined surface 13a pulls a portion below the flange 12a of the disk clamper 12 to the left in the drawing. Thus, the clamper 12 is released from the attraction force of the magnet 17 to the turntable 4a, and the 12cm CD6 or 8cm CD10 held between the clamper 12 and the turntable 4a is taken out.
[0015]
In addition, as a means for attaching and detaching a small 8 cm CD 10, a disk holder 11 is attached to the lid 1 so as to be rotatable around a rotation shaft 2, and a spring 14 is arranged between the lid 1 and the disk holder 11 to prevent the lid from closing. At the time of transition to the open state, the disc holder 11 rotates clockwise relative to the lid 1 that rotates counterclockwise within the range of the gap c due to the elastic force of the spring 14. . When the lid is closed, the contact rib 11a of the disc holder 11 comes into contact with the lower wall surface of the cabinet 5, so that the gap d between the surface of the 12cm CD 6 and the tip of the 8cm disc receiver 11b of the disc holder 11 is opposed to the elasticity of the spring 14. It keeps it constant. In addition, the tip of the 8 cm disc receiver 11b has an inclined surface so that the placed 8 cm CD 10 does not easily fall off.
[0016]
First, the operation of the disk mounting / dismounting apparatus configured as described above when an 8 cm CD is used will be described. First, when the lid 1 opens counterclockwise during the transition from the closed state to the open state, the clamper 12 is attracted to the turntable 4a by the attracting force of the magnet 17, so that the slope 13a of the clamper holder 13 is attached. When the lower side of the flange 12a of the disc clamper 12 is pulled to the left in the drawing, the clamper 12 and the 8 cm CD 10 simultaneously rotate clockwise about the point b. At this time, even if the lid 1 is opened to a certain extent, the disc holder 11 keeps the lid c until the gap c between the engaging portion 11c and the engaging portion 13b of the clamper holder 13 disappears due to the elastic force of the spring 14, and the disc holder 11 contacts each other. 1 is kept at the same position as the closed state. That is, since the disc holder 11 stays behind the transition of the lid 1 to the open state, when the disc clamper 12 is released from the attraction force of the magnet 17 to the turntable 4a and cannot hold the 8 cm CD 10, the point b is set. The lower end of the 8 cm CD 10, which has been rotated clockwise around the center, fits on the 8 cm disk receiver 11 b of the disk holder 11. And the presence of the inclined surface at the tip prevents the 8 cm CD 10 from falling off easily. The state at this time is shown in FIG.
[0017]
When the 8 cm CD is mounted, the CD is placed on the 8 cm disk receiver 11 b of the disk holder 11 with the lid 1 in the open state shown in FIG. At this time, since the disk holder 11 is pushed out toward the cabinet body 5 by the spring 14, the operability when mounting the 8 cm CD 10 is better than in the related art. Also, when the lid is closed with the 8 cm CD 10 accidentally dropped from the disc holder 11, the disc is not damaged because the disc holder 11 is bent by the elasticity of the spring 14. When the lid 1 is pressed in the closing direction by hand, the disc clamper 12, whose flange 12 a is pressed by the portion 1 a of the lid 1, is attracted to the magnetic turntable 4 a while holding the 8 cm CD 10 by the attraction force of the magnet 17. And fixed between the turntable 4a as shown in FIG. When the disc is taken out or when the disc is loaded, the disc holder 11 relatively projects from the lid 1 toward the main cabinet 5 by the gap c in FIG. 3, so that the 8 cm CD 10 can be easily held.
[0018]
In the case of the 12 cm CD, when the disk clamper 12 is released from the attraction force of the magnet 17 to the turntable 4 a and stops holding the 12 cm CD 6 when shifting from the closed state to the open state, the disk clamper 12 is placed on the recess 5 a of the main body cabinet 5. The 12 cm CD 6 may be dropped and mounted on the recess 5 a of the main body cabinet 5 at the time of mounting.
[0019]
As described above, according to the present embodiment, when the disk holder 11 moves away from the cabinet main body 5 in response to the shift to the open state of the lid 1 and moves away from the cabinet main body 5 and remains below the 8 cm CD 10, The slope 13a of the clamper holder 13 pulls the lower side of the flange 12a of the disc clamper 12 to the left in conjunction with the transition of the body 1 to the open state, thereby releasing the magnet 17 from being attracted to the turntable 4a and holding the magnet 17 therebetween. The 8 cm CD 10 is dropped on the disk holder 11 while rotating clockwise, and the dropped 8 cm CD 10 is held by the 8 cm disk receiver 11 b of the disk holder 11, so that the position of the rotation shaft 2 of the lid 1 is reduced. It can provide compact equipment that can be freely determined and is not subject to design restrictions. That.
[0020]
Although the description has been given of the example of the audio equipment using the compact disk, the disk-shaped recording medium may be used for any purpose, and the dimensional value of the disk is not limited.
[0021]
【The invention's effect】
As described above, according to the disk attaching / detaching apparatus of the present invention, the rotating shaft of the lid is arranged on or near the vertical line of a small-diameter disk having its surface arranged substantially vertically. Even if the rotating shaft is configured to be separated, a small-diameter disk can be accommodated in the disk receiver when the lid is opened, and in a sound reproduction device that is oriented to miniaturization, there is no design restriction. An advantageous effect of being able to be provided compactly is obtained. Further, when the disc is mounted at the time of opening the cover, the disc holder is pushed out by the spring, so that the mountability is improved as compared with the conventional case. Further, when the lid is closed with the small-diameter disc accidentally dropped from the disc holder, the disc holder is bent by the elasticity of the spring, so that an advantageous effect that the disc is not damaged can be obtained.
