Embodiment FIGS. 1 to 1O show an embodiment of a disk device according to the present invention. Note that a cover member 23, which will be described later, is omitted in FIG.

In FIG. 3 to FIG. 7, a magnetic disk device 10 as a recording/reproducing device has a disk device main body 1 as an internal mechanism.
0a, and a front bezel 35 that is attached to the front surface of the main body 10a and forms an operation surface.

The disk device main body 10a has a holder 15 on a frame 12 into which a cartridge 14 (indicated by a dashed line in FIG. 3) containing a magnetic disk 13 is inserted.

The holder 15 is provided to move up and down in accordance with the mounting and ejecting operations of the cartridge 14, and the top plate 15a has an opening 15 through which the magnetic head section 18 relatively enters.
b is provided. Further, on the top plate 15a of the holder 15, an L-shaped shutter lever 16 that opens the shutter (not shown) of the cartridge 14 in conjunction with the cartridge insertion operation is rotatably supported. The shutter lever 16 is biased clockwise (shuttle closing direction) by the tensile force of a coil spring 17, and the tip of the shutter lever 16 is inserted into the holder via an engagement pin 16a that engages with the shutter of the cartridge 14 or an arcuate hole 15c of the holder 15. It protrudes within 15.

As shown in FIGS. 3 and 7, the magnetic head unit 18 includes a carriage 19 that is movable in the disk radial direction (directions A and B), and a lower magnetic head that is provided on the upper surface of the tip of the carriage 19. 20 and the proximal end 1 of the carriage 19
arm 21 rotatably supported by arm 9a;
It consists of an upper magnetic head 22 provided on the lower surface of the tip. The carriage 19 is threadedly engaged with a lead screw (not shown) driven by a stepping motor (not shown), and moves in directions A and B on the frame 12 in accordance with the rotation of the lead screw, and moves the magnetic head 20. .22 in the tracking direction of the magnetic disk 13.

The arm 21 is urged in the C direction (see FIG. 7) by the pressing force of a torsion spring 19C provided at the base end 19a of the carriage 19. Further, a contact portion 21a protrudes from the side of the arm 21, and the top plate 15a of the holder 15 is in contact with this contact portion 21a. That is, before the cartridge is inserted, the arm 21 is pressed upward by the rise of the holder 15, and the upper magnetic head 22 is moved against the lower magnetic head 2.
Separate from 0. A cover member 23 is screwed into screw holes 12c formed in the edges 12a, 12b of the frame 12 so as to cover the upper part of the holder 15.

As shown in FIG. 8, the cover member 23 has five parts when viewed from above.
A flat part 23a formed in a letter shape, a notch part 23b formed to avoid the shutter lever 16, and a mounting part 23 that protrudes laterally from both sides and into which the mounting screw 25 is inserted.
c, and a bifurcated guide portion 23e having a guide groove 23d into which a pin 15f protruding from both side surfaces 15d and 15e of the holder 15 is fitted and guides the vertical movement of the holder 15.

A slider 24 is provided between the top plate 15a of the holder 15 and the cover member 23. The slider 24 has a U-shaped top plate 24a when viewed from above, and a top plate 24a.
It has side plates 24b and 24c that are bent downward from both side edges. The top plate 24a has a flat part 23 of the cover member 23.
Four elongated holes 24d, through which guide pins 26 implanted from below are inserted, are formed in the hole 23f drilled in the hole 23f so as to extend in the AB force direction. The elongated hole 24d has a hole 24d at the end through which the large diameter part 26a of the guide pin 26 is inserted, and a guide groove 2 in which the small diameter part 26b of the guide pin 26 slides.
4d, and so on.

Therefore, the slider 24 is supported by the guide pin 26 projecting downward from the cover member 23 so as to be slidable in the AB force direction.

Further, an L-shaped locking hole 24e is bored in the inner side of the top plate 24a of the slider 24.

This locking hole 24e is a long hole 24e1 extending in the AB force direction.
and a locking portion 24 extending in a direction perpendicular to the elongated hole 24e1.
e, and so on. Also, side plates 24b on both sides of the slider 24
, 24c are projecting pins 1 projecting from both sides of the holder 15.
It has an inclined groove 24f into which the groove 5f fits.

As shown in FIG. 8, at the front end of one side plate 24c of the slider 24, there is a mounting portion 2 for an eject button 27, which is an operation button.
4g protrudes toward the front (direction B). The mounting portion 24g protrudes outward from the insertion opening 24h of the cartridge 14, which is surrounded by the top plate 24a and side plates 24b and 24c.

Therefore, as shown in FIGS. 1 and 2, the front bezel 3
5 is a structure in which an eject button 27 is arranged in a longitudinally extending portion 35b of an insertion opening 35a of the cartridge 14;
There is no need for an extension in the thickness direction (Z direction) that was provided with the conventional eject button. As a result, the front bezel 3
The thickness H7 of the front bezel 5 is thinner than the thickness H1 of the conventional front bezel 5 shown in FIG. 21 by the thickness of the eject button 4b.

In general, disc devices are becoming thinner, and various proposals have been made for making the internal mechanism behind the front bezel 35 thinner, one example of which will be described later. However, no matter how thin the internal mechanism is, the conventional configuration shown in FIG.
By making b smaller, eject button 4b and insertion slot 1a
It is difficult to make the front bezel 5 thinner, and it is difficult to make the entire disk device thinner.

Therefore, according to the configuration of the magnetic disk device 10 of this embodiment, the front bezel 35 is made thinner, and the entire disk device can be made thinner in addition to the proposal to make the internal mechanism part thinner, which will be described later.

Furthermore, the center line C3 of the insertion slot 35a shown in FIG. An extension portion 35b is formed. Since the eject button 27 is disposed on this extension 35b, the length of the disk mount #10 in the longitudinal direction is not so large compared to the conventional one.

In the above embodiment, the eject button 27 is placed on the right side facing the insertion port 35a, but it goes without saying that the same effect can be obtained even if it is placed on the left side.

Reference numeral 28 denotes a compression spring that presses the slider 24 in the direction B. One end is hooked to the slider 24, and the other end is hooked to a hook portion 23g projecting downward from the end of the cover member 23. The slider 24 is displaced in the B direction by the pressing force of the compression spring 28 before the cartridge is inserted, and slides in the A direction when the eject button 27 is pressed during an eject operation.

A latch lever 29 is rotatably supported by a bottle 30 implanted in the cover member 23, and has a contact portion 29a against which the cartridge 14 comes into contact, and a locking hole 24e of the slider 24.
It consists of a locking part 29b that fits into the spring, and a locking part 29c that locks one end of the compression spring 31. Note that the compression spring 3I has the other end or a hooking portion 2 that protrudes downward from the end of the cover member 23.
3h, and urges the latch lever 29 in the D direction (counterclockwise). Therefore, when the slider 24 is ejected in six directions, the latch lever 29 rotates in the D direction and comes into contact with the locking portion 29b or the locking portion 24e of the locking hole 24e, and the slider 24 is displaced in the six directions. 24.

Incidentally, as shown in FIG. 8, the cover member 23 has a slider 2.
4. Latch lever 29. Since the compression springs 28 and 31 are assembled as described above, it is possible to form an assembly by assembling these parts in advance. Therefore, in the assembly process of the magnetic disk device IO, the cover member 23. Slider 24. Latch lever 2
9. By preparing the compression springs 28, 31 as one assembly, they can be assembled more efficiently in a shorter time than in the past.

As shown in FIGS. 6 and 7, the holder 15 is raised to the insertion position before the cartridge is inserted. Upper magnetic head 22
Since the arm 21 has a contact portion 21a that contacts the top plate 15a of the holder 15, it is raised 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 fit within this gap S.

That is, conventionally, this gap S was a space for the upper magnetic head 22 to move upward, and since no other members were provided, the space other than the space for the arm 21 to rotate was an unused space. In this embodiment, by providing the slider 24 in this unused space, the frame 12
It becomes possible to lower the insertion position of the holder 15 relative to the holder 15. As a result, the magnetic disk device 10 can be made thinner.

Therefore, since a thin plate material is not used for the slider 24, the device can be made thinner, so that the slider 24 does not lack strength, and reliability of the magnetic disk device IO and ejecting operation is ensured. In addition, the guide pin 26 that guides the sliding direction of the slider 24 can secure the protrusion dimension from the cover member 23 in the gap S between the holder 15 and the cover member 23 as in the conventional case, and the slider 24 is the guide bin 26
The sliding movement is reliably guided by the guide bin 26 without coming off.

32 is the magnetic disk 1 in the installed cartridge 14
3 is placed on the turntable, and rotates at a constant speed by the rotational driving force of a motor 33. Also, the motor 33 is connected to the frame 1
It is provided on a substrate 34 attached to the bottom surface side of 2. The motor 33 has a drive coil (not shown) provided on a substrate 34, and a turntable 32 provided on a rotor 33a. Therefore, the motor 33 is i within frame +2:
Since it is buried and provided on the substrate 33, it can be made thinner. In response to the lowering of the holder 15 as described above, the position of the turntable 32 relative to the frame 12 is lowered so that the mounting surface 32a approaches the upper surface 12d of the frame I2. . That is, the height of the projection from the upper surface 12d of the frame 12 to the mounting surface 32a of the turntable 32 is reduced. Therefore, the mounting position of the magnetic disk 13 is at a lower position closer to the frame 12, and the magnetic disk assembly ftl0 can be made thinner.

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

Magnetic disk device l before cartridge 14 is inserted
O is in the state shown in FIGS. 6 and 7. That is, the slider 24 is locked at the position where it slid in the entry direction.

Further, the arm 21 having the upper magnetic head 22 is attached to the holder 15.
It has also risen to the disc insertion position.

Now, when the cartridge 14 is inserted into the holder 15 as shown by the one-dot chain line in FIGS. 3, 6, and 7, the front end of the cartridge 14 moves in the insertion direction and the latch lever
The contact portion 29a is contacted.

Further, when the cartridge 14 is pressed in the input direction, the latch lever 29 rotates clockwise, and the locking portion 29b that fits into the locking hole 24e of the slider 24 is separated from the locking portion 24e and moves toward the elongated hole 24e1. Displaced to. This releases the latch lever 29 from locking the slider 24, and the slider 24 slides in the direction B due to the pressing force of the compression spring 28. At this time, the slider 24 is not supported by the four guide bins 26 and therefore stably slides in the B direction.

In the inclined grooves 24f provided on both side plates 24b and 24c of the slider 24, there are protruding bins 1 that protrude from both sides of the holder 15.
5f is engaged, as the slider 24 slides in the direction B, the protruding bottle 15f slides on the inclined groove 24f and is 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.

Further, as the holder 15 descends, the arm 21 rotates counterclockwise due to the pressing force of the torsion spring 19c, thereby lowering the upper magnetic head 22. In the process of being inserted into the holder 15, the cartridge 1a engages with a shutter (not shown) that closes the head abutment opening or with a bin 16a of the lever 16, and by rotating the lever 16 counterclockwise. It becomes open. Therefore, the magnetic disk 13 is placed on the turntable 32, and the magnetic heads 22 and 20 come into contact with the recording area described below on 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 and reproduction are 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 press the eject button 27 shown in FIGS. 1 and 2 in the in direction (in the case of FIG. 1, the direction toward the page). to press. As a result, the slider 24 slides in the inward direction, and the holder 15 rises to the disk insertion position. When the slider 24 moves in the inward direction,
The latch lever 29 rotates in the D direction due to the pressing force of the compression spring 31, and the locking portion 29b is rotated in the locking portion 24e of the locking hole 24e.
, to engage and lock. In this way, the latch lever 29
When the cartridge 14 rotates in the D direction, the cartridge 14 in the holder 15 is pressed by the abutting portion 29a of the latch lever 29 and ejected in the B direction.

Here, in the disk device 1O of this embodiment, FIGS.
As shown in the figure, the insertion port 35a and the eject button 27
21, the eject button 4b is not placed on a plane as in the conventional example shown in FIG. Collision with the cartridge 2 that pops out from the cartridge 2 is eliminated, and operability during ejection is improved.

Although the above embodiment has been described using a magnetic disk device as an example, the present invention is not limited to this and can of course be applied to, for example, an optical disk device or a magneto-optical disk device.

Next, a second embodiment of the present invention will be described.

The external appearance of a magnetic disk device 40 which is a second embodiment of the disk device of the present invention explained in FIGS. 11 to 19 is as follows.
Magnetic disk device 1 of the first embodiment shown in FIGS. 1 and 2
The appearance is equivalent to 0.

The magnetic disk device 40 is different from the magnetic disk device 10 in its internal mechanism, and the details thereof will be explained below.

The magnetic disk device 40 includes a disk device main body 40a, which is an internal mechanism, and a front bezel 65, which is attached to the front surface of the main body 40a and forms an operation surface.

- In FIG. 11, a mounting device 45 for mounting a cartridge (indicated by a one-dot chain line in FIG. 11) containing a magnetic disk 43 is incorporated on the main frame 42 of the magnetic disk device main body 40a. This mounting device 45
As shown in FIG. 12, the holder 46 is moved up and down between the case insertion position where the cartridge 44 is inserted and the cartridge installation position where the cartridge 44 is installed. It consists of a guide section 47 which is a guiding slider.

The holder 46 has holding parts 46b and 46c bent to hold both sides of the cartridge 44 on both sides of the top plate 46a.
The holding portions 46b and 46cl knees are each provided with two protruding pins 46d that protrude laterally. Holder 46
The top plate 46a has an opening 46e into which a magnetic head section 48 having upper and lower magnetic heads (not shown) is fitted;
A dogleg-shaped lever 49 for opening a shutter (not shown) of the cartridge 44 inserted into the holder 46 is rotatably provided. Note that the lever 49 is supported by a shaft 46f of the top plate 46a, and is biased clockwise by the tensile force of a coil spring 50. The lever 49 is attached to the holder 46 so that its tip engages with the shutter of the cartridge 44.
There is a retention bottle 49a that protrudes inward.

As shown in FIG. 13, the main frame 42 is U-shaped when viewed from the front, with left and right plates 42b and 42c standing vertically on both sides of a bottom plate 42a. The guide portion 47 described above is provided on the bottom plate 42a. Guide part 47
As shown in FIG. 12, the holding portion 46b of the holder 46
and the left side plate 42b of the main frame 42, and the second guide member 51 interposed between the holding portion 46c of the holder 46 and the right side plate 42c of the main frame 42.
and a connecting member 53 whose one end 53d is connected to the first guide member 51 and the other end 53e is connected to the second guide member 52.

The first guide member 51 extends in the cartridge insertion direction (directions A and B) and is provided to stand up from the bottom plate 42a of the main frame 42. Further, the first guide member 51 is provided with inclined grooves 51a and 51b into which a protruding pin 46d protruding laterally from the holding portion 46b of the holder 46 is fitted.

The second guide member 52 extends in a direction parallel to the first guide member 51, that is, in the case insertion direction (A, B direction), and stands up from the bottom plate 42a of the main frame 42. Further, the second guide member 52 has the holding portion 4 of the holder 46.
An inclined groove 52a into which a protruding bottle 46d protruding laterally from 6c is fitted.

52b is bored.

As shown in FIGS. 11, 12, and 14, an eject button 54, which is an operation button, is provided at the front end of the second guide member 52 so as to face forward (direction B). This eject button 54 is provided in a direction in which the second guide member 52 is bent and moves away from the other guide member 51, that is, in a position shifted outward away from the insertion opening 46f of the cartridge 44.

Therefore, as shown in FIGS. 1 and 2, the front bezel 6
5 has a structure in which, like the front bezel 35 of the first embodiment, the eject button 54 is arranged in the longitudinal extension 65b of the insertion opening 65a of the cartridge 44, and the thickness of the front bezel 65 shown in FIG. The dimension H7 is designed to be thinner than the thickness dimension H7 of the conventional front bezel 5 shown in FIG. 21 by the thickness dimension of the eject button 4b.

Further, due to the configuration of the magnetic disk device 40 of this embodiment, the front bezel 65 can be made thin without significantly increasing its longitudinal dimension, similar to the magnetic disk device IO described in the first embodiment. , along with the proposal to reduce the thickness of the internal mechanism section, which will be described later, it becomes possible to reduce the thickness of the entire disk device.

In the above embodiment, the second
It goes without saying that the same effect can be obtained by providing the eject button 54 on the first guide member 52 or the first guide member 5I on the left side.

As shown in FIG. 14, the eject button 54 and the inclined groove 52a
A retaining portion 52c having a bifurcated protrusion is provided at the lower end between the two. Further, a locking groove 52d is provided at the rear lower end of the guide member 52, and a locking portion 52e to which one end of the coil spring 55 is hooked is provided at the rear upper end.

The other end of the coil spring 55 is hooked to a hook portion 42d provided on the inner wall of the side plate 42c of the main frame 42. Therefore, the guide member 52 is urged in the direction B by the tensile force of the spring 55.

Before inserting the cartridge, the latch lever 56 is inserted into the locking groove 52d.
Since the locking portion 56b is in contact with the guide member 52, the guide member 52 is locked at the position displaced in the entry direction.

The latch lever 56 is provided in the inner part of the holder 46 and is supported by a shaft 42f on the main frame 42. The latch lever 56 includes a contact portion 56a that stands up so as to come into contact with the cartridge 44 inserted into the holder 46, and a locking portion 56b that is locked in the locking groove 52d of the guide member 52.
and has.

The latch lever 56 before the cartridge is inserted is attached to the coil spring 5.
7 in the counterclockwise direction, so that the locking portion 56b fits into the locking groove 52d of the guide member 52.

Further, as shown in FIG. 15, the second guide member 51 has a retaining portion 5 having a bifurcated protrusion at the lower end on the front side of the inclined groove 51a.
1c, and a hooking portion 51d on which one end of the coil spring 58 is hooked is provided at the upper center end. The other end of the coil spring 58 is hooked to a hook portion 42e provided on the inner wall of the side plate 42b of the main frame 42. Therefore, the guide member 51 is urged in the input direction by the tensile force of the spring 58. That is, the guide members 51 and 52 are urged in opposite directions by 180 degrees, and the inclined groove 51a.

51b, 52a, and 52b are respectively inclined in opposite directions.

The connecting member 53 is horizontally suspended on the bottom plate 42a of the main frame 42, and has a mounting hole 53a in the center. Mounting hole 53a
A screw 59 that is screwed into the mounting portion 42a of the bottom plate 42a is inserted through the bottom plate 42a, and the connecting member 53 is provided so as to be able to swing around the screw 59 as an axis. The connecting member 53 has a first arm portion 53b extending to the left side and a second arm portion 53c extending to the right side, and protruding pins 53d and 53e are provided at the tips of both arm portions 53b and 53c. has.

The connecting member 53 has protruding pins 53d, 5 as shown in FIG.
3e are fitted into the engaging portions 51c, 52c of the guide members 51, 52 and connected.

Since the guide members 51, 52 and the connecting member 53 are each formed into a narrow plate shape, it is easy to manage the dimensions of each part. Furthermore, since the shape is less likely to warp or distort than those made of a wide sheet metal, there is no risk that the vertical movement of the holder 46 will become inoperable even if a thin sheet metal is used. Therefore, the mounting device 45 can also be adapted to make the device thinner.

Also, 1st. Since the second guide members 51 and 52 are separate pieces, even if the holding parts 46b and 46c of the holder 46 are slightly distorted or the position of each protruding pin 46d is slightly misaligned, the first guide member 51,52 is a separate member. The second guide member 51,52 is the protruding pin 53d of the connecting member 53.

Since it is only connected to 53e, the above error can be flexibly absorbed. In addition, since the connecting member 53 is only horizontally suspended on the bottom plate 42a of the main frame 42, the installation space for the connecting member 53 is small, and it is also possible to install other members in the space above the bottom plate 42a. The space above 42a can be used for growing purposes.

Next, the operation when installing the cartridge 44 into the magnetic disk device 4o having the above configuration will be explained.

Before the cartridge 44 containing the magnetic disk 43 is inserted into the holder 46, the holder 46 is raised to the cartridge insertion position shown by the one-dot chain line in FIG. The second guide member 52 is displaced in six directions and is locked by a latch lever 56.

Now, when the cartridge 44 is inserted into the holder 46,
The front end of the cartridge 44 is the contact part 5 of the latch lever 56
6a. Further, when the cartridge 44 is pressed in the A direction, the latch lever 16 rotates clockwise, and the locking portion 56b or the locking groove 52d of the guide member 52 is disengaged. Therefore, as shown in FIG. 17, one guide member 52 slides in the direction B by the tensile force of the spring 55. A pair of guide members 51 and 52 arranged on both sides of the holder 46 are connected to the communication member 5.
3, so that when one guide member 52 slides in the direction B, the connecting member 53 rotates clockwise, and at the same time the other guide member 51
slides in six directions.

Therefore, as shown by solid lines in FIG.
, 51b, 52a, and 52b and descend to the cartridge mounting position.

Further, when ejecting the installed cartridge 44, the eject button 54 shown in FIGS. 1 and 2 is pressed in six directions. As a result, the guide member 52 integrated with the eject button 54 slides in six directions, and the communication member 53 also 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, the holder 46 is connected to the protruding pin 46d or both guide members 51.
52 inclined grooves 51a, 51b.

52a and 52b to the case insertion position.

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

Here, in the magnetic disk device 40 of the present embodiment, as shown in FIGS. 1 and 2, the insertion slot 65a and the eject button 54 are located at the 21st
As shown in the figure, it is not a flat layout,
Eject button 5, which frequently occurred in the conventional arrangement
There is no possibility that the finger pressing 4 collides with the ejected cartridge 44 that pops out from the insertion opening 65a, and the operability during ejection is improved.

Note that the guide members 51 and 52 remain in the vertical position A.

When sliding in direction B, the holder 46 and the main frame 42
Lateral play is restricted between the side plates 42b and 42c, and the case slides smoothly in response to case insertion or ejection operation.

Further, in the above embodiment, the connecting member 53 is provided below the holder 46, but is not limited to this, for example, as shown in FIG.
The connecting member 53 may be swingably provided on a shaft 60a on the lower surface of the cover 60 provided at the upper end of the main frame 42. In this case, the bottom plate 42a of the main frame 2
There is no need for the mounting portion 42a to protrude, and an extra space between the holder 46 and the bottom plate 42a is not required, and the compartment can be made thinner.

Further, as shown in FIG. 19, the connecting member 53 is attached to the holder 4.
It may be swingably mounted on the top plate 46a of No. 6. In that case, since the connecting member 53 moves up and down together with the holder 46, the ends 53b1.53CI of both arm parts 53b and 53c
The long holes 51f and 52f (the tip 53b1 is not shown) are bent downward and extend laterally, and the elongated holes 51f and 52f extend upward and downward in the guide members 51 and 52 (the hole 51f is not shown). ).

and a tip 53b of the connecting member 53.

53C1 into the elongated hole 51f of the guide member 51.52.

52f. As a result, the protruding pins 53d, 53 provided at the tips 53b, 53c+ of the connecting member 53
e is secured to be connected to the guide members 51 and 52, as in the above embodiment, regardless of the vertical position of the holder 46.

Although the above embodiment has been explained using a magnetic disk device as an example, the present invention is not limited to this, and the present invention is also applicable to a mounting device for mounting a recording medium other than a magnetic disk, such as an optical disk device or a magneto-optical disk device. I can do it.

Since the guide members 51 and 52 have a plate shape extending in the sliding direction, they may be formed of a sheet metal film or may be integrally formed of synthetic resin.

Furthermore, in the above embodiment, it goes without saying that the sliding direction of the first guide member 51 and the second guide member 52 may be opposite to that in the above embodiment.

Effects of the Invention As described above, according to the present invention, by arranging the operation button in the longitudinal extension of the disk cartridge insertion opening, the thickness dimension of the conventional operation button can be omitted, and the disk The front bezel of the device can be made thinner.

This makes the layout of the operation surface of the device to which the disk device is installed advantageous, and the miniaturization of the device to which the disk device is installed can be promoted from the viewpoint of the layout and configuration of the operation surface.

In addition, in the disk device of the present invention, the operation button and the disk cartridge insertion slot are not arranged in a planar manner, so when ejecting the disk cartridge, the finger pressing the operation button and the ejected disk pop out from the insertion slot. Interference with the disk cartridge is eliminated and the operability of the disk device is improved.
