[0024] As shown in FIG. 4, the cartridge 28 is made of a thin plastic case. A mounting section 28a in which a compact disc 29 (indicated by a dashed line) is mounted; , is open on the bottom side and the above-mentioned turntable 20 and optical pickup 21 face each other. It has an opening 28b. 30 is a shutter, which is located at the front part 28c of the cartridge 28; and the bottom side, and automatically slides in directions C and D to open and close the opening 28b on the bottom side. It is currently set up. Normally, the shutter 30 is supported by a spring (not shown), as indicated by the broken line in FIG. energized to the closed position.

[0025] Further, the lower surface of the lid 28d of the cartridge 28 is fitted into the center hole of the disk 29, A clamper 28e (indicated by a broken line) is provided to hold this.

[0026] Here, the mounting operation when the cartridge 28 is mounted on the disk device 1 will be described. This will be explained with reference to FIGS. 5 to 7.

[0027] As shown in FIG. 5, when playing the disc 29 in the cartridge 28, the cart The ridge 28 is inserted into the holder 5 with the front portion 28c at the beginning. Cartridge 2 8 moves in the B direction while sliding on the sliding parts 5g and 5h of the holder 5 on both sides.

[0028] When the cartridge 28 is inserted, the front part 28c is moved to the shutter opening/closing lever. 23 and rotates the lever 23 clockwise. Therefore, lever - 23 causes the shutter 30 of the cartridge 28 to slide in the C direction and open. Open the mouth portion 28b.

[0029] As shown in FIG. 6, when the cartridge 28 is completely inserted into the holder 5, the shutter is closed. The lever 30 is fully opened, and the protrusion 27 of the lever 23 fits into the straight part 26b of the groove 26. . At this point, the limit switch (not shown) is turned on and the slider drive unit 1 is turned on. 4 motors 15 are driven. The driving force of the motor 15 is the worm 16 and pinion 1. 7, transmitted to the slider 4 via the rack 18.

[0030] Therefore, the slider 4 slides in the A direction and lowers the holder 5. in this way The cartridge 28 inserted into the holder 5 is loaded into the mounting position of the disk device 1. It will be worn.

[0031] That is, the disc 29 housed in the cartridge 28 is placed on the turntable 20. It is placed on top and clamped between the clamper 28e and the turntable 20. Further, the optical pickup 21 faces the recording surface of the disk 29 through the opening 28b. do. The disc 29 is now in a playable state, and the loading operation is completed.

[0032] Note that the ejecting operation is the opposite of the above-mentioned mounting operation. That is, the eject switch When a switch (not shown) is turned on, the slider drive unit 14 is turned on. The motor 15 rotates in the reverse direction and drives the slider 4 in the B direction. Slider 4 slides in direction B. The holder 5 rises as it rides. Then, the protrusion 27 of the lever 23 6, the lever 23 rotates counterclockwise when it reaches the arcuate portion 26a. to press the cartridge 28 in the A direction to eject it.

[0033] Next, when installing a disk 29 that is not housed in the cartridge 28, I will explain.

[0034] When installing only the disk 29, use an adapter (slider) as shown in Figures 8 and 9. The moving object) 31 is mounted in the holder (insertion section) 5.

[0035] The adapter 31 is connected to a first tray on which a compact disc 32 with a diameter of 12 cm is placed. A second tray section on which a tray section 33 and a compact disc 34 with a diameter of 8 cm are placed. 35 are provided at different levels. 36 is a turntable 20 and an optical picker The cup 21 is an opening facing the disks 32 and 34, and 37 is an opening for taking out the disk. It is a recess.

[0036] The adapter 31 has a pair of arms 31a and 31b that protrude from both sides in the direction B. A locking portion 38 is provided on the side surface of the left arm portion 31a. This locking part 3 8 is supported by a thin plate-like support portion 39, and has an inclined surface 38a on the tip side. slope 38a is spaced apart from the side surface of the arm 31a through a gap, so it is not pressed in the D direction. When the support portion 39 is bent, the support portion 39 is displaced into the flexible arm portion 31a. Also, the adapter 31 is on both sides of the bottom. It has guide grooves 40 and 41 extending in directions A and B, and a clamper 42 is supported on the top surface. A holding arm 43 is rotatably provided.

[0037] The arm 43 is torsioned so that it rotates upward (in the E direction) about the shaft 43a. It is energized by a spring 44. Therefore, when ejecting, as shown in Figure 10, The clamper 42 is located away from the disc 32 (rotated approximately 45 degrees), and the disc Insertion and removal of the hook 32 can be easily performed.

[0038] As shown in FIGS. 11 and 12, the adapter 31 with the above configuration has arm portions 31a and 31b. is inserted into the holder 5 with . At that time, the guide groove 40 of the adapter 31, The guide member 7 of the holder 5 fits into the 41, and guides the movement of the adapter 31 in the A and B directions. Ido. Further, the locking portion 38 that protrudes laterally from the left arm portion 31 has an inclined surface 38a. By slidingly contacting the stopper 8 in the holder 5, it is displaced into the arm 31a and the stopper Get over 8. In this way, when the adapter 31 is inserted into the holder 5, the upper surface The right edge abuts against the roller 13.

[0039] Next, the disk 32 is placed on the tray section 33 as shown in FIG. and , press the arm 43 in the F direction to bring the clamper 42 into contact with the center hole of the disk 32. let

[0040] When the mounting button (not shown) is turned on, the motor of the adapter drive unit 9 is turned on. The motor 10 is rotationally driven, and the rotational driving force of the motor 10 is transmitted through rollers 11, 12, 13. and is transmitted to the adapter 31.

[0041] In FIG. 12, the roller 13 rotates counterclockwise and moves the adapter 31 in the direction B. make it move. The adapter 31 is guided by the guide member 7 and does not press the lever 23. while sliding it to the insertion completion position shown in FIG. 13. Note that if the adapter 31 moves in direction B, When the adapter 31 is moved, the locking portion 38 does not come into sliding contact with the side plate 5b of the holder 5 and does not hinder the movement of the adapter 31. It looks like this. Also, the arm 43 of the clamper 42 is held against the top plate 5a of the holder 5. and held in the clamped position.

[0042] When the adapter 31 reaches the insertion completion position, the above-mentioned cartridge 28 is inserted. Similarly, the limit switch (not shown) is turned on and the slider drive unit 14 is turned on. The motor 15 is driven to rotate.

[0043] Therefore, the slider 4 slides in the A direction by the rotational driving force of the motor 15, As a result, the holder 5 descends together with the adapter 31 and reaches the mounting position shown in FIG. It will be installed. Therefore, the disk 32 in the adapter 31 is placed on the turntable 20. and is clamped between the clamper 42 and the turntable 20 to rotate. It is rotated and reproduced by the optical pickup 21.

[0044] Note that the ejecting operation is performed in the opposite manner to the above-described mounting operation. In other words, Iji When the slider drive unit (not shown) is turned on, the slider drive unit is turned on. The motor 15 of the motor 14 rotates in the opposite direction, driving the slider 4 in the B direction. Slider 4 As the holder 5 slides in the B direction, the holder 5 rises and the adapter 31 is inserted into the completed position. Return to

[0045] Next, the motor 10 of the adapter drive unit 9 is driven to rotate in reverse, and the roller 13 rotates clockwise. This causes the adapter 31 to slide in the A direction and connect the disk It is ejected from position 1.

[0046] When the eject operation is completed, the adapter 31 removes the disk as shown in Figures 15 and 16. It protrudes more than the device 1 and stops at a position where the locking portion 38 abuts against the stopper 8. The arm 43 provided on the adapter 31 is moved by the elastic force of the spring 44. As it slides from the holder 5 in the A direction, it rotates in the E direction as shown in FIG. .

[0047] Therefore, when the eject operation is completed, the disk 32 placed on the adapter 31 is The overall position is protruding from the disk device 1 in the A direction, and the arm 43 is Since it opens upward, it can be easily taken out. In addition, the operation of ejecting the disc To do this, insert your finger into the recess 37 of the adapter 31 and lift the periphery of the disk 32. It's fine.

[0048] Also, as mentioned above, the adapter 31 protrudes greatly so that the entire disk 32 can be seen. This makes it easy to insert the next disc.

[0049] In this way, in the disk device 1, the disk stored in the cartridge 28 is 29, insert the cartridge 28 into the holder 5. Insert the disc 32 that can be inserted and is not housed in the cartridge 28 as is. In this case, insert the adapter 31 into the holder 5 and insert the tray part 33 of the adapter 31 into the holder 5. The disc 32 can be placed and mounted on the disc 32. Therefore, the user A disc can be loaded into the disc device 1 and played with or without the disc 28. can.

[0050] In the above embodiment, the arm 43 supporting the clamper 42 is supported by the elastic force of the spring 44. However, this spring 44 can be removed and the rotation can be performed manually. Of course, the arm 43 may be rotated in the E and F directions.

[0051] A modification of the present invention is shown in FIGS. 17 and 18. In both figures, there is a disk 32 inside the housing 2. A clamp mechanism 51 is provided to clamp the. Therefore, the adapter 31 has The clamper 42 and arm 43 become unnecessary.

[0052] This clamp mechanism 51 is arranged laterally from the ends of the side plates 5b and 5c in the B direction of the holder 5. A clamp arm 47 rotatably supported by support parts 45 and 46 protruding from the , a clamper 48 provided on the bottom surface of the tip of the clamp arm 47; It consists of a coil spring 49 that energizes the coil spring 47.

[0053] The coil spring 49 has one end hooked to the chassis 3 and the other end hooked to the clamp arm 47. The clamp arm 47 is attached to the disc clamping direction. It is strong.

[0054] The clamp arm 47 has protruding parts 47b, 47 which protrude laterally on both sides of the hooking part 47a. It has c. These protrusions 47b and 47c are located on the cam plate 50 that stands up from the slider 4. It is in sliding contact with the inclined portion 50a.

[0055] When ejecting or before inserting the adapter 31, the protrusions 47b and 47c are connected to the cam plate 50. Since it is in sliding contact with the upper part of the inclined part 50a, it is displaced upward (direction F). So Therefore, there is no risk that the clamper 48 will interfere with the disk insertion or ejection operation. . When the adapter 31 is inserted to the insertion completion position and the slider 4 slides in the A direction, The holder 5 is lowered together with the adapter 31 to the mounting position. At the same time, the cam plate 50 also The lower part of the inclined part 50a slides on the protruding parts 47b and 47c of the arm 47. come into contact with

[0056] Therefore, as shown in FIG. 19, the arm 47 is rotated in the F direction by the elastic force of the spring 49. Then, the clamper 48 clamps the disk 32 placed on the adapter 31.

[0057] In this way, the adapter 31 is not provided with the clamper 42 and the arm 43. This makes it easy to replace the disc (installation, removal) when ejecting the disc. .

[0058] In addition, when installing the cartridge 28, as shown in FIG. 1 operates as described above, the clamper 48 comes into contact with the top surface of the cartridge 28. Ru. Therefore, the cartridge 28 is stably held within the holder 5 without wobbling. Ru.

[0059] Note that although the above embodiment has been explained using a compact disc player as an example, this embodiment Of course, the invention can also be applied to disk devices that use other disk-shaped recording media. It is a theory.
