SOLUTION: As to a door body 3 capable of opening/closing an inserting/ ejecting part by the turning of a door surface, the shape of the door surface in the direction of the thickness is made to set so as unable to contact with the parts other than the neighborhood of the outer edge part of a disk-like recording medium passing through the inserting/ejecting part, even in the case the door surface 31 is positioned at the any turning position. For instance, the shape of the door surface 31 in the direction of the thickness is formed to include the bent or inclined part so as to become the almost projecting state facing to the front surface side of the door surface. Or, the arrangement is made on the door surface so that an almost recessed rib constituting the shape of the door surface in the direction of the thickness is formed on the inner surface side of the door surface.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disk drive capable of performing a recording or reproducing operation on a disk-shaped recording medium such as an optical disk or a magneto-optical disk, and more particularly to a door for opening and closing a disk insertion / removal portion. It is related to the shape.

[0002]

2. Description of the Related Art Disk drives are widely used in computer equipment, AV equipment, and the like. However, in a disk drive, the intrusion of dust and the like into the equipment causes a decrease in performance. In order to insert / eject a disk, the hole for inserting / removing the disk is closed as much as possible. For example, in a slot loading type disk drive device, a door is provided on the front side of the disk insertion / removal hole so that the disk insertion / removal hole is closed by the door except when a disk is inserted or removed.

FIG. 14 shows an example in which a door 51 is formed on the front side of a disk insertion / removal hole 52 of a disk drive device 50. The door 51 is rotated, for example, about a lower shaft (not shown) so that a disc insertion / removal hole 52 is formed.
The disk 90 can be inserted into the apparatus and the disk can be removed (ejected) in the open state as shown in the figure.

[0004]

By the way, the rotation of the door 51 is automatically performed, for example, according to a predetermined operation of the user at the time of inserting or removing the disk. The turning operation is controlled so as not to make contact. However, the door 51 may come into contact with the disk 90 due to a user operation error or some operation error. As an example, for example, as shown in FIG. 14, the user does not remove the disk 90 while the disk 90 is partially removed from the inside of the apparatus, and performs an operation such that the door 51 is closed. Is the case.

In such a case, for example, as schematically shown in FIG. 15 as a front view and a side view, the upper end of the door 51 hits the recording surface of the disk 90,
0 may damage the recording surface. Of course, scratches on the recording surface will have a significant adverse effect on the data reading performance or writing performance of the disk 90.

[0006] In order to avoid such contact between the door and the disk, there is a door in which the shape of the door is devised as shown in FIG. FIGS. 16A to 16D are schematic diagrams of the front direction and the side direction, respectively. In this disk drive device 60, as can be seen from FIG.
When viewed from the front, the shape of the upper end of the door 61 is substantially V-shaped. Then, FIG. 16 (a) → (b) →
As shown in (c), the door 61 is opened by being rotated about a shaft at the lower end thereof, and the disc insertion / removal hole 62 is opened.
Is exposed.

[0007] In this case, as shown in FIG.
Even when the door 1 rotates in the closing direction, the door 61 only comes into contact with the end (outer edge) of the disk 90 because the upper surface of the door 61 is substantially V-shaped. As is well known, in an optical disk or a magneto-optical disk, the circular outer edge is not used as a data recording portion. The data recording portion extends to a position slightly inward from the outer edge. Therefore, even if the door 61 and the vicinity of the outer edge of the disk 90 come into contact with each other, no damage occurs in the data recording portion.

Therefore, in the disk drive device 60 shown in FIG. 16, even if the door 61 contacts the disk 90,
It does not adversely affect data read / write performance.
However, when the door 61 is viewed from the front in the normal state, the upper side must be formed in a substantially V-shaped shape (or a shape similar thereto) as shown in FIG. This is a major limitation on the external design of the drive device. In other words, there is a problem that the degree of freedom in design and development of the front panel are greatly impaired, for example, it is necessary to allow a certain degree of poor appearance.

[0009]

SUMMARY OF THE INVENTION In view of the above problems, the present invention prevents a door from abutting against a data recording portion of a disk to cause a scratch, and provides a degree of freedom in external design. The purpose is to improve.

Therefore, in a disk drive device,
With respect to the insertion / removal portion for inserting or removing the disk-shaped recording medium, the door surface has a door body that can be opened and closed by rotating the door surface, and the door body,
Regardless of the rotational position of the door surface, the shape of the door surface in the thickness direction is set so that the door surface does not come into contact with anything other than near the outer edge of the disk-shaped recording medium passing through the insertion / removal portion. To For example, the door surface has a shape including a curved or inclined portion so that the shape in the thickness direction becomes substantially convex toward the front side of the door surface. Alternatively, a substantially concave rib forming the shape of the door surface in the thickness direction is formed on the inner surface side of the door surface.

[0011] That is, by devising the shape of the door surface in the thickness direction so as to prevent contact only with the vicinity of the outer edge of the disk-shaped recording medium, damage to the data recording portion of the disk can be prevented and the door can be prevented. The shape of the surface does not need to be a special shape that does not become a rectangle when viewed from the front. In other words, the degree of freedom in setting the shape of the door surface as viewed from the front is increased.

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, various examples of a disk drive device according to an embodiment of the present invention will be described, particularly regarding the shape of a door. First, a first embodiment will be described with reference to FIGS.

FIGS. 1, 2 and 3 are perspective views showing a part of a front panel 2 of a disk drive device 1 of this embodiment. 1 shows a state in which a door 3 arranged on a front panel 2 is closed, FIG. 3 shows a state in which the door 3 is opened, and FIG. 2 shows a state in which the door 3 is rotating for opening and closing. Is shown.

As can be seen from the drawings, the front panel 2 of the disk drive device 1 is provided with a disk insertion / removal hole 4 through which a disk can be inserted / removed. Door 3 on the front side of hole 4
Are rotatably mounted. Normally, the disc insertion / removal hole 4 is closed by the door 3 as shown in FIG. 1, and when the disc is inserted or taken out, the door 3 is moved from FIG. Thus, the disk insertion / removal hole 4 is exposed.

The front panel 2 is also provided with, for example, an operator 5 for eject operation and the like, a connection terminal 6 for headphones and the like. For example, according to the eject operation,
The turning operation of the door 3 is performed.

FIG. 4A is a plan view and a front view of the door 3.
As shown in FIG. 4 (b), as can be seen from FIG. 4 (a) and FIGS. 2 and 3, a shaft attachment portion 32 is provided at the lower portion on the inner surface side of the door 3, and as shown in FIG. The rotation shaft of the door 3 is formed by the shaft 8 being inserted through the attachment portion 32. An arm 33 is formed on the inner surface side of the door 3, and as shown in FIG. 3, the spring 33 is locked to the arm 33 from the inside of the apparatus. Thereby, the rotation of the door 3 is urged in the closing direction as shown in FIG.

In the case of this embodiment, as can be clearly seen particularly from FIG. 4, the door surface 3 serving as the main body of the member as the door 3 is formed.
1, that is, the portion that actually opens and closes the disk insertion / removal hole 4 has a curved shape such that the shape in the thickness direction is convex toward the front side of the door surface 31. The shape of the door surface 31 prevents the door 3 from damaging the data recording area of the disk 90.

FIGS. 5A to 5D are schematic views in the front and side directions, respectively, showing the state of the door 3 in each rotation position state. FIGS. 5 (a), 5 (b) and 5 (c) show the states in the rotational position state corresponding to FIGS. 1, 2 and 3, respectively. Since the upper end portion of the door 3 is curved in the thickness direction, the upper end is straight when viewed from the front in the state of FIG. 5A, but is frontal in the case of FIGS. It is concave when viewed from the direction. Therefore, as shown in FIG.
Even if the door 3 is rotated in the direction in which the door 3 is closed when half of the disk 90 is taken out, the upper end of the door surface 31 only comes into contact with the end (outer edge) of the disk 90. Since the outer edge of the disk is not used as a data recording portion, even if the contact as shown in FIG. 5D occurs, the data recording portion is not damaged. That is, even if the door 3 is in any rotational position,
The shape of the door surface in the thickness direction is set so that the disk 90 passing through the disk insertion / removal section 4 cannot come into contact with anything other than the vicinity of its outer edge.

Further, in the case of the present embodiment, the upper side of the door surface 31 is linear as can be clearly seen from FIG. Therefore, there is no need to curve or incline the upper side of the door surface 31 when viewed from the front direction, that is, the front shape of the door surface 31 is not limited in order to prevent damage to the data recording surface. Thereby, the degree of freedom as the design of the front panel 2 is improved, and a good-looking appearance can be realized.

Next, a second embodiment will be described with reference to FIGS. FIGS. 6A and 6B show a plan view and a front view of the shape of the door 3. As can be seen from this figure, in this example, the door surface 31 has a shape including inclined portions on both sides so that the shape in the thickness direction becomes convex toward the front side of the door surface 31. FIG. 7 shows a state of this example corresponding to the state of FIG.
6 has a shape as shown in FIG. 6, and as shown in FIG. 7, even if the door 3 is turned in a direction in which the door 3 is closed in a state where half of the disk 90 is taken out, the upper surface end of the door surface 31 is formed. The portion only comes into contact with the end (outer edge) of the disk 90, and no damage occurs to the data recording portion. That is, also in this example, even when the door surface 31 is in any rotation position, the door 3 cannot contact the disk 90 passing through the disk insertion / removal portion 4 except in the vicinity of the outer edge thereof. The shape of the door surface in the thickness direction is set.

Further, also in the case of the second embodiment, the upper side of the door surface 31 is linear as can be clearly seen from FIG. 6B. Therefore, there is no need to curve or incline the upper side of the door surface 31 when viewed from the front direction.
As a result, the degree of freedom is improved, and a good-looking appearance can be realized.

Next, a third embodiment will be described with reference to FIGS. FIGS. 8A and 8B show a plan view and a front view of the shape of the door 3. As can be seen from this figure, in this example, the shape of the door surface 31 in the thickness direction is the door surface. 31
The shape includes a V-shaped inclined portion so as to protrude toward the front surface side. Therefore, as shown in FIG. 9, even when the door 3 is rotated in the direction in which the door 3 is closed when half of the disk 90 is taken out, the upper end of the door surface 31 contacts the end (outer edge) of the disk 90. It only touches and does not damage the data recording part. Thus, in this example as well, the door 3 does not contact the disk 90 passing through the disk insertion / removal portion 4 except in the vicinity of the outer edge thereof, regardless of the rotation position of the door surface 31. Then, the shape of the door surface in the thickness direction is set.

Further, also in the case of the third embodiment, the upper side of the door surface 31 is linear as can be seen from FIG. Therefore, there is no need to curve or incline the upper side of the door surface 31 when viewed from the front, and the degree of freedom as the design of the front panel 2 is improved, and a good-looking appearance can be realized.

Next, a fourth embodiment will be described with reference to FIGS. 10, 11 and 12. FIG. FIG. 10 is a perspective view of a part of the front panel 2 of the disk drive device 1 according to the fourth embodiment, and shows a state where the door 3 is opened as shown in FIG. FIGS. 11A and 11B show a plan view and a front view of the shape of the door 3.

As can be seen from these figures, in this example,
The front surface itself as the door surface 31 is formed in a rectangular parallelepiped shape, and is not curved or inclined so that the entire door surface 31 is convex toward the front surface. However, a rib 34 is formed on the inner surface side of the door surface 31, and the rib 34 is formed as shown in FIG.
As can be seen from FIG. 1 (a), it is concave when viewed in the opposite front direction. That is, a substantially concave rib 34 is formed on the inner surface side of the door surface 31 as a part of the shape of the door surface 31 in the thickness direction.

Therefore, as shown in FIG.
When the door 3 is rotated in the direction in which the door 3 is closed in a state where half of the door 3 is taken out, the rib 34 on the inner surface side of the door surface 31 comes into contact with the disk 90.
4 is concave, the contact is only at the end (outer edge) of the disk 90, and no damage occurs to the data recording portion. That is, also in this example, even when the door surface 31 is in any rotation position, the door 3 cannot contact the disk 90 passing through the disk insertion / removal portion 4 except in the vicinity of the outer edge thereof. The shape of the door surface in the thickness direction is set.

Further, also in the case of the fourth embodiment, the upper side of the door surface 31 is linear as can be seen from FIG. Therefore, it is not necessary to curve or incline the upper side of the door surface 31 when viewed from the front, and the degree of freedom is improved as the design of the front panel 2, and a good-looking appearance can be realized.

A plan view of a door 3 as a fifth embodiment,
FIGS. 13A and 13B are front views. In this case, door surface 3
The entire inner surface 35 of the device 1 has a concave shape like the rib 34, and the front surface has a planar shape (does not expand forward). Even in this case, the same effects as those of the above examples can be obtained.

While various embodiments have been described above, the present invention can be embodied in various other modifications.
For example, the shape of the rib in the fourth embodiment may not be curved in a concave shape, but may be provided with an inclined portion so as to form a V-shape. Further, in each example, the door 3 is rotated about the lower part as an axis. However, the present invention is similarly applicable to a type in which the disk insertion hole is exposed by rotating upward about the upper part as an axis. Applicable to

[0030]

As described above, according to the present invention, regardless of the pivot position of the door surface, the door body comes into contact with the area other than the vicinity of the outer edge of the disk-shaped recording medium passing through the insertion / removal section. Since the shape of the door surface in the thickness direction is set so that it cannot be done, it is possible to reliably prevent damage to the data recording part of the disk, and it is not necessary to make the door surface a special shape when viewed from the front. No, therefore the degree of freedom is improved as the design of the front panel of the disk drive device,
There is an effect that a good-looking appearance can be realized.
