For this press The rib 23 has a stepped portion 23a. One part 23b (the left part of the step part 23a in FIG. 2) across the step part 23a has a height HI of the cartridge 5 placed on the tray 2 when the cartridge 5 is placed on the tray 2 here. It is formed to be higher than the height hi up to this cartridge 5 when 5 is placed. The other portion 23c from the step portion 23a (the right portion from the step portion 23a in FIG. 2) is a pressure restricting means for restricting the pressing device 3 from pressing the bare disk D2, and its height H2 is The cartridge 5 is formed to be lower than the height hi (see FIG. 5) of the cartridge 5 when the cartridge 5 is placed on the tray 2. Further, the other portion 23c has a height H2 when the bare disk 6 is placed on the tray 2, here, when the bare disk 6 is placed in one of the placement recesses 21a and 21b. It is formed to be higher than the height h2 to the bare disk. Note that one portion 23b of the pressing rib 23 is formed in a range in which a contact member 32, which will be described later, contacts the pressing device 3 when the tray 2 is moved. The other end 23c is formed in a range where the contact member 32 comes into contact with the tray 2 at the disc playback position.

[0028] The holding device 3 presses the tray 2 or the cartridge 5 placed on the tray 2 from the cartridge placement side (in FIG. 2, by force from the top to the bottom). Two pressing devices 3 are provided so as to face both side surfaces of the tray 2, and each of the pressing devices 3 includes an arm member 31, a contact member 32, and an urging member 33.

The arm member 31 is disposed on the side facing the cartridge mounting side of the tray 2 of the disk device 1, here, on the inner wall surface (not shown) facing the cartridge mounting side surface of the tray 2 of the casing 4. . The arm member 31 has a rotating shaft 34 attached in the vicinity of one end thereof. The rotating shaft 34 is rotatably supported by a bearing 35 attached to the inner wall surface (not shown). That is, one end of the arm member 31 is supported so as to be rotatable in the direction of force in the tray 2 and in the direction of arrow B in the figure.

[0030] The contact member 32 has a cylindrical shape, and is formed of a material that is hardly damaged even when it comes into contact with the tray 2 or the cartridge 5 such as a synthetic resin. The contact member 32 comes into contact with the pressing rib 23 formed on the tray 2. The contact member 32 is rotatably supported on the other end of the arm member 31 via a rotation shaft 36. [0031] The urging member 33 urges the arm member 31 in a direction in which the arm member 31 is directed toward the tray 2, in the direction of arrow B in the figure.

In contact. Therefore, the urging member 33 generates an urging force in a direction in which the arm member 31 is directed toward the tray 2 between the casing 4 and the arm member 31.

[0032] The casing 4 has an opening 41 formed on the front surface thereof. A loading / unloading door 42 is supported in the opening 41 so as to be freely opened and closed. The carry-in / out door 42 is always urged in the closing direction by a carry-in / out door urging member (not shown). Accordingly, when the tray 2 is carried out, the carry-in / out door 42 is pressed by the tray 2 in the opening direction, and the carry-in / out door 42 is opened against the urging force acting on the carry-in / out door 42. Here, as shown in FIG. 3, the opened carry-in / out door 42 is controlled to be closed in the closing direction by the tray 2 and maintained in the opened state. Further, when the tray 2 is carried in, the restriction of the rotation of the opened carry-in / out door 42 in the closing direction is released, so the carry-in / out door 42 is closed by the urging force.

The casing 4 has a plurality of guide members 43a to 43f arranged on inner walls (not shown) facing both side surfaces of the tray 2, respectively. The plurality of guide members 43a to 43f are provided at a plurality of locations in the moving direction of the lay-up 2 with a pair of guide members 22 sandwiching the guide ribs 22 formed on both side surfaces of the tray 2 (here, three locations (43a and 43a). 43b, 43c and 43d, 43e and 43f). The plurality of guide members 43a to 43f guide the movement of the tray 2 in the moving direction. The pressing device 3 includes a pair of guide members 43c, 43d and a pair of guide members 43e, between a pair of guide members on the carry-in / out door 42 side among the plurality of guide members 43a to 43f. The contact member 32 is arranged so as to come into contact with the rib 23 of the tray 2 positioned between 43f.

It should be noted that the cartridge 5 accommodates the disk D1, as shown in FIG. The force cartridge 5 includes a main body portion 51 and a door portion 52. Inside the main body 51, a disk D1 is stored. The door 52 can slide in either direction on both side surfaces of the cartridge 5. In addition, the door 52 is biased by a door biasing member (not shown), and when no external force is applied, the door 52 closes to the body 51, that is, outside the cartridge 5, the disk D1 In a position where the The Reference numeral 53 denotes a positioning hole into which the positioning pin 21c is inserted.

Next, the operation of the disk device 1 will be described. First, the case where the cartridge 5 is carried into the disk device 1 will be described. First, as shown in FIG. 3, the cartridge 5 is placed on the tray 2. Here, the tray 2 is moved to the disk reproducing position / cartridge mounting position by a tray moving means (not shown). The pressing device 3 is configured such that when the cartridge 2 of the tray 2 is placed, the contact member 32 comes into contact with one portion 23b of the pressing rib 23, and the urging force of the urging member 33 acting on the contact member 32 2 Press the cartridge mounting side force as well.

At this time, the tray 2 is guided by the pair of guide members 43c and 43d and the pair of guide members 43e and 43f at the cartridge mounting position. As described above, the contact member 32 of the pressing member 3 is a portion of the pressing rib 23 between the pair of guide members 43c and 43d and the pair of guide members 43e and 43f (one portion 23b). Will be pressed toward the cartridge mounting side. Accordingly, the pressing device 3 presses the tray 2 against the plurality of guide members, here the guide members 43c and 43e. That is, the tray 2 can be kept parallel to the moving direction, that is, horizontal. Thereby, it is possible to suppress the tray 2 from sagging due to its own weight due to the clearance between the tray 2 and the plurality of guide members 41a to 41f, in particular, the clearance between each pair of guide members and the guide ribs 22. In addition, when the tray 2 moves to the cartridge mounting position, the tray 2 also presses the tray 2 and presses the tray 2 against the urging force to act on the loading / unloading door 42, thereby causing the tray 2 to move. Can be prevented from lifting. As a result, the quality of the disk device 1 can be improved.

Then, as shown in the figure, the cartridge 5 is placed on the placement portion 21 of the tray 2 located at the cartridge placement position. At this time, the positioning pin 21c of the tray 2 is inserted into the positioning hole 53 of the cartridge 5 (see FIG. 4).

Next, as shown in FIGS. 4 and 5, the cartridge 5 is carried into the disk device 1. Here, the tray 2 is moved to the disk reproduction position by the tray moving means (not shown). During the movement of the tray 2, the contact member 32 of the pressing device 3 moves to a portion 23b of the pressing rib 23 whose height H2 is higher than the height hi up to the cartridge 5 placed on the tray 2. Keep in touch with. Therefore, the biasing member acting on the contact member 32 The urging force of 33 keeps pressing the tray 2 from the cartridge mounting side. That is, while the tray is moving, the pressing device 3 also presses the tray 2 with a cartridge mounting side force, and the tray 2 is against the disk device 1 in this case, among the plurality of guide members 41a to 41f. It is pressed against the materials 41a, 41c, 41e. As a result, it is possible to suppress the tray 2 from becoming unstable while the cartridge mounting position force of the tray 2 is moved to the disk reproduction position, and the operation stability of the tray 2 can be improved.

In addition, during the movement of the tray 2 to the cartridge placement position force to the disk playback position, it is not the cartridge 5 placed on the tray 2 but the tray 2 itself that is pushed by the holding device 3. Accordingly, since the pressing device 3 is suppressed from pressing the cartridge 5 when the tray 2 moves to the disk reproducing position as well as the cartridge placement position force, the cartridge 5 can be prevented from being damaged. The pressing device 3 presses the tray 2 or the cartridge 5 by bringing the contact member 32 into contact with the pressing rib 23 or the cartridge 5 of the tray 2. Accordingly, the clearance between the cartridge 5 and the disk D1 during recording / reproduction of the disk D1 can be secured with a simple configuration, and the stability of the operation of the tray 2 during the movement of the tray 2 can be improved. At the same time, the damage to the cartridge 5 can be suppressed.

[0040] When the tray 2 moves to the disk playback position, the door portion 52 of the cartridge 5 is opened by sliding the slide member 24 interlocked with the movement of the tray 2 in a direction perpendicular to the movement direction of the tray 2. Then, the disc D1 stored in the cartridge 5 is exposed to the outside, and the disc D1 can be reproduced and recorded. At this time, the contact member 32 of the pressing device 3 opposes the other portion 23c of the pressing rib 23. However, the other portion 23c is lower in height HI than the height hi up to the cartridge 5 placed on the tray 2. Therefore, the contact member 32 presses the cartridge 5 from the cartridge mounting side by the urging force of the urging member 33 acting on the contact member 32. That is, when the tray 2 is positioned at the disk reproduction position, the pressing device 3 also presses the cartridge mounting side force on the cartridge 5 mounted on the tray 2 and presses the cartridge 5 against the tray 2. As a result, the movement of the cartridge 5 relative to the disk D1 during recording / reproduction of the disk D1 is suppressed, and it is possible to ensure the alignment with the disk D1. [0041] When the loaded cartridge 5 is unloaded from the disk device 1, the tray 2 is moved from the disk reproduction position to the cartridge mounting position by tray moving means (not shown). Even in this case, the contact member 32 of the pressing device 3 continues to contact the one portion 23b, and continues to press the tray 2 with the cartridge mounting side force. Therefore, the tray 2 disc playback apparatus force is also prevented from becoming unstable during movement of the tray 2 to the cartridge mounting position, and the operation stability of the tray 2 can be improved. When the tray 2 moves from the disk playback position to the cartridge mounting position, the pressing device 3 is suppressed from pressing the cartridge 5, so that damage to the cartridge 5 can be suppressed.

Next, a case where the bare disk D2 is carried into the disk device 1 will be described. First, the bare disk D2 is placed in one of the placement recesses 21a and 21b of the tray 2 (see FIG. 1). Next, as shown in FIGS. 1 and 2, the bare disk D2 is carried into the disk device 1. Here, the tray 2 is moved from the cartridge placement position to the disk reproduction position by a tray moving means (not shown). Even in this case, the contact member 32 of the pressing device 3 continues to contact the one portion 23b and continues to press the tray 2 with the cartridge mounting side force. Accordingly, the disc playback device force of the tray 2 is also restrained from becoming unstable during movement of the tray 2 to the cartridge mounting position, and the operation stability of the tray 2 can be improved.

[0043] When the tray 2 moves to the disc playback position, the contact member 32 of the pressing device 3 opposes the other portion 23c of the pressing rib 23. However, the other portion 23c has a height HI higher than the height h2 up to the bare disk D2 placed on the tray 2. Therefore, the contact member 32 also presses the cartridge mounting side force against the other portion 23c of the pressing rib 23 by the urging force of the urging member 33 acting on the contact member 32. That is, when the tray 2 is positioned at the disk reproduction position, the other portion 23c, which is a pressing restricting means, restricts the pressing device 3 from pressing the bare disk D2 against the tray 2. Accordingly, the pressing device 3 presses the cartridge 5 against the tray 2 when the cartridge 5 is placed on the tray 2, and the presser 3 when the bare disk D2 is placed on the tray 2. Do not press the disk D2 against the tray 2. As a result, the disk device 1 can perform reproduction recording of the disks Dl and D2 regardless of whether the disk Dl stored in the cartridge 5 or the bare disk D2 is placed on the tray 2. It should be noted that the configuration of the pressing device provided in the disk device according to the present invention is not limited to the configuration of the pressing device 3 that is effective in the above embodiment. FIGS. 6-1 to 3 are diagrams showing other configuration examples of the disk device according to this embodiment. In FIG. 6-1 to FIG. 3 and FIG. 1 to FIG.

[0045] As shown in FIG. 6-1, the guide ribs 22 on both side surfaces of the tray 2 are formed with stepped portions 22a. The arm member 31 of the pressing device 3 is formed with a sliding pin 37. The sliding pin 37 slides on the cartridge mounting side of the guide rib 22 as the tray 2 moves.

[0046] The height H3 of one portion 22b of the guide rib 22 across the step portion 22a (the left portion of the step portion 22a in Fig. 6-1) is such that the sliding pin 37 has the one portion 22b.

With the urging force of 33, the cartridge 5 also presses the cartridge mounting side force.

[0050] When the bare disk D2 is placed on the tray 2, when the tray 2 is located at the disk reproduction position, as shown in FIG. It contacts with the other part 22c of the ribs 22 for guides. At this time, the contact member 32 is not in contact with one portion 23 c of the pressing rib 23. That is, when the bare disk D2 is placed on the tray 2, the pressing device 3 is in contact with the other portion 22c of the guide rib 22 when the bare disk D2 is placed on the tray 2 at the disc playback position of the tray 2. The tray 2 is pressed against the cartridge placement side by the biasing force of the biasing member 33 acting on the sliding pin 37.

[0051] As described above, even if the pressing device 3 is configured, the clearance between the cartridge 5 and the disk D1 at the time of recording / reproducing of the disk D1 can be secured, and the tray 2 is moved while the tray 2 is moving. The stability of the operation can be improved and the damage to the cartridge 5 can be suppressed.

In the above embodiment, the contact member 32 is rotatable with respect to the arm member 31, but may be fixed. Further, a force in which an urging force is applied to the arm member 31 by the urging member 33 by the urging member 33. The arm member 31 itself has elasticity, and the urging force may be generated like the urging force to the tray 2.

As described above, the disk apparatus according to this embodiment is the disk apparatus 1 that reproduces information recorded on the disk D1 housed in the cartridge 5 and records information on the disk D1. Cartridge placement position force for placing cartridge 5 Tray 2 moves to the disc playback position where playback and recording of the disc D1 stored in this placed cartridge 5 is performed. Is also equipped with a pressing device 3 that presses the cartridge mounting side force and presses the cartridge 5 at the cartridge playback position to press the cartridge mounting side force, thereby ensuring the clearance between the cartridge 5 and the disk D1 during recording and playback of the disk D1. This can improve the stability of the operation of the tray 2 during the movement of the tray 2 and Scratching can be suppressed. Industrial applicability
