The thickness dimension H ₂ of 35 is thinner than the thickness dimension H ₁ of the conventional front bezel 5 shown in FIG. 21 by the thickness dimension of the eject button 4b.

In general, the disk device is being made thinner, and various proposals have been made for making the internal mechanical portion at the rear of the front bezel 35 thin, as described later. However, no matter how thin the internal mechanism section is, in the conventional configuration as shown in FIG. 21, from the viewpoint of operability of the eject button 4b, the eject button 4b can be made smaller, or the eject button 4b and the insertion port can be made smaller. Since it is not possible to make 1a close to each other, it is difficult to make the front bezel 5 thin, which prevents the thinning of the entire disk device.

Therefore, according to the configuration of the magnetic disk device 10 of the present embodiment,
The front bezel 35 becomes thin, and it becomes possible to reduce the thickness of the entire disk device together with the proposal to reduce the thickness of the internal mechanism portion described later.

Further, the center line C ₂ of the insertion port 35a shown in FIG. ₁ is provided at a position displaced to the left by the dimension a from the center line C ₁ of the disk device 10, and this displacement causes the front bezel 35 to be inserted. An extension 35b of the mouth 35a is formed. And this extension 35
Since the eject button 27 is provided in b, the disk device 10
The dimension in the longitudinal direction of is not so large as compared with the conventional one.

Although the eject button 27 is arranged on the right side of the insertion port 35a in the above embodiment, the same effect can be obtained with the left side.

The other end of the compression spring 31 is hooked on a hooking portion 23h protruding downward from the end of the cover member 23, and biases the latch lever 29 in the D direction (counterclockwise direction). Therefore, when the slider 24 is ejected in the A direction, the latch lever 29 rotates in the D direction and the locking portion 29b is locked in the locking hole 24e.
The slider 24 abutting on the locking portion 24e ₂ of FIG.

As shown in FIG. 8, the cover member 23 has a slider 24,
Since the latch lever 29 and the compression springs 28 and 31 are assembled as described above, it is possible to assemble them by assembling these parts in advance. Therefore, in the assembling process of the magnetic disk device 10, by preparing the cover member 23, the slider 24, the latch lever 29, and the compression springs 28, 31 as one assembly, the time is shorter than in the conventional case. Can be assembled efficiently.

As shown in FIGS. 6 and 7, the holder 15 is raised to the insertion position before the cartridge is inserted. Since the arm 21 of the upper magnetic head 22 has the contact portion 21a that comes into contact with the top plate 15a of the holder 15, it rises together with the holder 15. Therefore, a gap S is required between the holder 15 and the cover member 23 for the arm 21 to rotate upward. The slider 24 is provided between the holder 15 and the cover member 23 so as to be accommodated in the gap S. That is, conventionally, this space S is a space for moving the upper magnetic head 22 upward, and since no other member is provided, it is an unused space other than the space for rotating the arm 21. In this embodiment, by providing the slider 24 in this unused space, the insertion position of the holder 15 with respect to the frame 12 can be lowered. As a result, the magnetic disk device 10 can be made thinner.

Therefore, the device can be made thin without using a thin plate material for the slider 24, so that the slider 24 does not have insufficient strength, and the reliability of the magnetic disk device 10 and the eject operation is secured.
Further, the guide pin 26 for guiding the sliding direction of the slider 24 is provided in the gap S between the holder 15 and the cover member 23.
The projection size from the cover member 23 can be secured as in the conventional case, and the slider 24 can be surely guided by the guide pin 26 in the sliding operation without coming off from the guide pin 26.

Reference numeral 32 is a turntable on which the magnetic disk 13 in the mounted cartridge 14 is placed, and is rotated at a constant speed by the rotational driving force of the motor 33. The motor 33 is provided on a substrate 34 attached to the bottom surface side of the frame 12. The motor 33 has a drive coil (not shown) provided on the substrate 34, and the rotor 33
A turntable 32 is provided on a. Therefore, since the motor 33 is embedded in the frame 12 and provided on the substrate 33, the motor 33 can be made thin. Then, in the turntable 32, the position of the turntable 32 with respect to the frame 12 is lowered so that the mounting surface 32a approaches the upper surface 12d of the frame 12 in response to the lower position of the holder 15 as described above. . That is, the protruding height from the upper surface 12d of the frame 12 to the mounting surface 32a of the turntable 32 is small. Therefore, the mounting position of the magnetic disk 13 is at a lower position closer to the frame 12, and the magnetic disk device 10 can be made thinner.

Here, the operation of the magnetic disk device 10 having the above configuration will be described.

The magnetic disk device 10 before the cartridge 14 is inserted is in the state shown in FIGS. 6 and 7. That is, the slider 24 is locked at the position slid in the A direction. The arm 21 having the upper magnetic head 22 is raised to the disk insertion position together with the holder 15.

Contact 29a. Further, when the cartridge 14 is pressed in the direction A, the latch lever 29 rotates clockwise, and the locking portion 29b fitted into the locking hole 24e of the slider 24 is disengaged from the locking portion 24e ₂ and the long hole 24e ₁ Displace to the side. As a result, the locking of the slider 24 by the latch lever 29 is released, and the slider 24 slides in the B direction by the pressing force of the compression spring 28. At this time, the slider 24 slides stably in the B direction while being supported by the four guide pins 26.

Since the projecting pins 15f projecting from both sides of the holder 15 are engaged with the inclined grooves 24f provided on the both side plates 24b, 24c of the slider 24, the projecting pin 15f is slid along with the slider 24 in the B direction. The slant groove 24f is slidably contacted and pressed downward. As a result, the holder 15 is lowered to the disk mounting position shown in FIGS. 9 and 10, and the magnetic disk 13 in the cartridge 14 is placed on the turntable 32.

Also, as the holder 15 descends, the arm 21
The pressing force of 19c rotates counterclockwise to lower the upper magnetic head 22. A shutter (not shown) that closes an opening for contacting the head of the cartridge 14 in the process of being inserted into the holder 15 is engaged with a pin 16a of the lever 16 so that the lever 16
It is opened by the counterclockwise rotation of. Therefore, the magnetic disk 13 is placed on the turntable 32, and the magnetic heads 22 and 20 contact the upper and lower recording surfaces of the magnetic disk 13.

Thereafter, when the turntable 32 is rotationally driven by the motor 33, the magnetic disk 13 rotates together with the turntable 32, and magnetic recording / reproduction is performed by the magnetic heads 20 and 22.

Next, when ejecting the magnetic disk 13 mounted as described above together with the cartridge 14, first, the eject button 27 shown in FIGS. 1 and 2 is in the A direction (in the case of FIG. 1, the direction toward the paper surface). Press on. This allows the slider 24
Slides in the A direction, and the holder 15 rises to the disc insertion position. When the slider 24 moves in the A direction, the latch lever
29 is rotated in the D direction by the pressing force of the compression spring 31,
29b engages and locks the locking portion 24e ₂ of the locking hole 24e. In this way, when the latch lever 29 rotates in the D direction, the cartridge 14 in the holder 15 is pressed by the contact portion 29a of the latch lever 29 and ejected in the B direction.

Here, in the disk device 10 of the present embodiment, as shown in FIGS. 1 and 2, the insertion port 35a and the eject button 27 are the second
Unlike the conventional example shown in Fig. 1, it does not have an overlapping arrangement on the plane, so it frequently happened in the conventional arrangement configuration.
The finger that pressed the eject button 4b is ejected and the insertion slot 1a
The collision with the cartridge 2 that pops out of the cartridge is eliminated, and the operability during ejection is improved.

It is displaced in the direction and locked by the latch lever 56.

Now, when the cartridge 44 is inserted into the holder 46, the front end of the cartridge 44 contacts the contact portion 56a of the latch lever 56. Further, when the cartridge 44 is pressed in the A direction, the latch lever 16 rotates clockwise and the locking portion 56b is disengaged from the locking groove 52d of the guide member 52. Therefore, as shown in FIG. 17, one guide member 52 slides in the B direction by the tensile force of the spring 55. A pair of guide members arranged on both sides of the holder 46
Since 51 and 52 are slidably connected to each other via a connecting member 53, the connecting member 53 rotates clockwise in conjunction with sliding of one guide member 52 in the B direction, At the same time, the other guide member 51 slides in the A direction.

Therefore, in the holder 46, as shown by the solid line in FIG. 13, the projecting pins 46d on both sides slidably contact the inclined grooves 51a, 51b, 52a, 52b of the guide members 51, 52 and descend to the cartridge mounting position.

Also, when ejecting the mounted cartridge 44,
The eject button 54 shown in FIGS. 1 and 2 is pressed in the A direction. As a result, the guide member 52 integrated with the eject button 54 is
While sliding in the direction, the connecting member 53 rotates counterclockwise. Therefore, the first guide member 51 connected to the second guide member 52 via the connecting member 53 slides in the B direction. Therefore, in the holder 46, the projecting pin 46d rises to the case insertion position along the inclined grooves 51a, 51b, 52a, 52b of the guide members 51, 52.

When the second guide member 52 is displaced in the A direction, the second guide member 52 is locked by the latch lever 56 that rotates counterclockwise. At the same time, the first guide member 51 is locked at the position displaced in the B direction via the connecting member 53. The cartridge 44 is ejected in the B direction by the rotation of the latch lever 56.

Here, in the magnetic disk device 40 of the present embodiment, as in the magnetic disk device 10 of the first embodiment, as shown in FIGS. 1 and 2, the insertion port 65a and the eject button 54 are as shown in FIG. In the conventional arrangement configuration, the finger pressing the eject button 54 does not collide with the cartridge 44 that is ejected and jumps out from the insertion opening 65a. The operability during ejection is improved.

When the guide members 51 and 52 slide in the A and B directions in the upright state, lateral play between the holder 46 and both side plates 42b and 42c of the main frame 42 is restricted. It can slide smoothly in response to insertion or eject operation.

Further, although the connecting member 53 is provided below the holder 46 in the above embodiment, the present invention is not limited to this. For example, as shown in FIG. 18, the connecting member 53 may be provided on the lower surface of the cover 60 provided on the upper end of the main frame 42. The shaft 60a may be swingably provided. In this case, the bottom plate 42a of the main frame 2 does not have to be provided with the mounting portion 42a ₁ , and an extra space between the holder 46 and the bottom plate 42a is not required, and the device can be thinned accordingly.

Further, as shown in FIG. 19, the connecting member 53 may be swingably mounted on the top plate 46a of the holder 46. In that case, since the connecting member 53 moves up and down together with the holder 46, both arm portions 53b, 53
c of the tip 53b _1, 53c ₁ (tip 53b ₁ is not shown) by bending the downward causes extends further laterally, the guide member 5
Long holes 51f and 52f (holes 51f are not shown) are formed in 1,52 so as to extend upward and downward.

Then, the tips 53b ₁ and 53c ₁ of the connecting member 53 are connected to the guide member 51,
Insert into the long holes 51f and 52f of 52. As a result, the connecting member 5
The protruding pins 53d and 53e provided on the tips 53b ₁ and 53c ₁ of 3 are the same as in the above embodiment regardless of the vertical position of the holder 46.
The connection with 1,52 is secured.

Although the magnetic disk device has been described as an example in the above embodiment, the present invention is not limited to this, and the present invention can be applied to a mounting device such as an optical disk device or a magneto-optical disk device that mounts a recording medium other than a magnetic disk. You can

Since the guide members 51 and 52 are plate-shaped and extend in the sliding direction, they may be made of sheet metal, or may be integrally formed of synthetic resin.

In the above embodiment, the sliding direction of the first guide member 51 and the second guide member 52 may of course be opposite to that of the above embodiment.

EFFECTS OF THE INVENTION As described above, according to the present invention, in a disk device having a structure in which an operating force is applied to an internal mechanism and the disk cartridge is ejected by the operating force, the operation button is extended in the longitudinal direction of the disk cartridge insertion port. By disposing the operation button in the thickness direction, the dimension in the thickness direction of the conventional operation button can be omitted, and the front bezel of the disk device can be made thin. This is advantageous for the arrangement configuration of the operation surface of the device on which the disk device is mounted, and the downsizing of the device on which the disk device is mounted can be promoted from the viewpoint of the arrangement structure of the operation surface.

Further, in the disc device of the present invention, the operation button and the insertion port of the disc cartridge are not arranged so as to overlap each other in a plane. The interference with the disc cartridge is eliminated, and the operability of the disc device is improved.
