Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disc drive device, and more particularly, to a technique that enables a disc-shaped recording medium to be loaded in a small space by interlocking a lid and a disc tray.

[0002]

2. Description of the Related Art In a disk drive device, in order to load a disk-shaped recording medium, a part of the housing is used as a rotary lid, and the rotary lid is rotated to expose a disk mounting surface in the housing. There is something to do.

FIG. 17 shows a conventional disk drive device a.
This is an example, and a part of the top plate c of the housing b is a rotating lid body d, and by opening the rotating lid body d, a disk mounting for mounting the disk-shaped recording medium e The part f is exposed. The disk drive device a of this type is widely used in so-called CD radio cassette recorders.

FIG. 19 shows another example g of a conventional disk drive device. A disk tray j is slidably provided with respect to the housing h through an opening formed in a front plate i of the housing h. There is one in which the disc-shaped recording medium e can be placed on the disc placing portion k of the disc tray j by popping the tray j forward from the housing h. Disk drive device g of this type
Is widely used in computers and the like.

[0005]

By the way, the former type of disk drive device a is a disk-shaped recording medium e.
It is necessary to make the size of the rotary lid body a little larger than that of the disc-shaped recording medium e in order to enable the placement on the disc mounting portion f.

Moreover, the opening / closing angle of the rotating lid body d is preferably set to about 90 degrees in order to easily load the disk-shaped recording medium e.

Therefore, in the disk drive device a provided with such a rotary lid d, the disk drive device a can be used only in a place having a relatively large space above it. There was a problem (see FIG. 18). For example, there is a space above the housing b only up to the horizontal line indicated by the one-dot chain line in FIG.

In the latter type of disk drive device g, normally, the disk tray j is moved from the front plate i of the housing h.
The disk-shaped recording medium e cannot be mounted on the disk mounting portion k of the disk tray j unless the disk-shaped recording medium e is almost the same as or slightly protrudes from the disk-shaped recording medium e. There has been a problem that the disk drive device g cannot be used unless it has a relatively large space (see FIG. 20). For example, only the vertical line indicated by the one-dot chain line in FIG.
It seems that there is no space in front of.

In any case, in the conventional disk drive device a or g as described above, in order to load the disk-shaped recording medium e into the disk drive device a or g, these housings b or h are used. It could only be used in places where there was a relatively large space around it.

Therefore, it is an object of the present invention to provide a disk drive device that enables loading of a disk-shaped recording medium into the disk drive device without a large space around the disk drive device.

[0011]

In order to solve the above-mentioned problems, the disk drive device of the present invention comprises a housing in which a main plate has a loading opening for inserting and removing a disk-shaped recording medium. A lid that slides with respect to the casing to open and close the loading opening, a disc tray on which a disc-shaped recording medium is placed and slides with respect to the casing, and a sliding direction of the lid and a disc tray. And a reverse slide means for moving the lid and the disc tray so that the sliding directions are opposite to each other, the loading opening and the disc mounting portion of the disc tray are opposed to each other, and the lid is opened. At this time, the total amount of the drawn amount of the disc tray and the opened amount of the loading opening is made substantially the same as the diameter of the disc-shaped recording medium.

Therefore, in the disk drive device of the present invention, when the disk-shaped recording medium is loaded into the disk drive device, the lid does not rotate above the housing, and the disk drive device projects toward the main surface. Since the size of the disk tray used is about half the diameter of the disk-shaped recording medium, it can be used in a relatively narrow space of the disk drive device.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the disk drive device of the present invention will be described below with reference to the embodiments shown in the accompanying drawings.

Each of the embodiments shown in the drawings applies the disk drive device of the present invention to a compact disk player (hereinafter referred to as "CD (compact disk) player").

1 to 6 show a first embodiment of a disk drive device according to the present invention. A CD player 1 is provided with a housing 2 and a housing 2 which can be pulled out. , A disc tray 5 having a disc mounting portion 4 on which the CD 3 is placed, a lid 7 for opening and closing a loading opening 6 for inserting and removing the CD 3, and the lid 7 and the disc tray 5 in opposite directions. And a reverse slide means 8 for moving to.

The loading opening 6 formed in the housing 2 is
Of the top plate 9 as the main face plate of, is formed in the front half,
The left-right width thereof is substantially the same as or slightly larger than the diameter D of the CD 3, and the front-rear width thereof is substantially equal to or slightly larger than half the diameter D of the CD 3.

Further, the loading opening 6 of the housing 2 is formed in the housing front plate 1.
It is also formed continuously on the upper part of 0, and this part serves as a pull-out opening 11 through which the disc tray 5 is pulled out.

The lid 7 is substantially the same as the left-right width dimension of the loading opening 6 and has a slightly large front-rear width dimension, and slides in the front-rear direction at a position overlapping the lower surface of the housing top plate 9 from below. The loading opening 6 is freely provided, and the loading opening 6 is closed by sliding forward, and the loading opening 6 is opened by sliding backward. Further, the lid 7 is made of a transparent plate, so that the inside of the housing 2 can be visually recognized when the loading opening 6 is closed, and the state where the CD 3 is rotating can be seen. It has become.

A tension coil spring 12 is provided between the lid 7 and the back plate of the housing 2, whereby the lid 7 is
Always urged in the opening direction.

The disc tray 5 is a CD 3 when viewed from above.
Has a substantially square shape with one side that is the same as or slightly larger than the diameter D of, and is provided slidably in the front-rear direction at the upper part of the housing 2 and below the lid body 7. In the housed state, the drawer opening 11 is closed so that the front surface of the disc tray 5 and the housing front plate 10 are flush with each other. A substantially front half of the tray 5 in the front-rear direction projects from the housing front plate 10.

Below the disc tray 5, a CD mechanical deck (corresponding to the disc drive mechanism according to claim 4) 13 for rotating the CD 3 and recording or reproducing a signal for the CD 3 is provided. The turntable 14 of the CD mechanical deck 13 is arranged so as to project on the upper surface of the disc tray 5, and this portion serves as the disc mounting portion 4.

Such a disc tray 5 and the lid 7
Are connected by reverse slide means 8 so as to slide in opposite directions (front-rear direction).

That is, the reverse slide means 8 is attached to the tray side rack 15 attached to the disc tray 5 side, the lid side rack 16 attached to the lid 7 side, and these two racks 15 and 16. And an interlocking gear 17 that meshes.

Specifically, the tray-side rack 15 having tooth surfaces 15a formed on the left and right side surfaces of the disc tray 5 is provided above.
Is attached to the rear half of the disc tray 5, and
On the left and right side surfaces of the lid body 7, lid side racks 16 having tooth surfaces 16a formed below are attached over substantially the entire length thereof.

The interlocking gear 17 is rotatably supported by the housing 2 at substantially the center in the front-rear direction in the housing 2, and is meshed with the tray rack 15 and the lid rack 16.

As a result, for example, when the lid 7 slides rearward, that is, to the open side, the lid-side rack 16 rotates the interlocking gear 17, and the interlocking gear 17 pushes the tray-side rack 15 forward. When the disc tray 5 slides forward, that is, in the direction in which it is pulled out from the housing 2, and conversely, when the disc tray 5 slides backward, that is, toward the storage side, the lid 7 slides forward,
The loading opening 6 is closed.

Further, each rack 15 and 1 with the interlocking gear 17
The meshing position with 6 is such that when the interlocking gear 17 is in mesh with the rear end of the lid side rack 16, the interlocking gear 17 is in mesh with the front end of the tray side rack 15. When the lid 7 closes the loading opening 6, the disc tray 5 is stored in the housing 2, and when the lid 7 opens the loading opening 6, The disc tray 5 is adapted to be pulled out from the housing 2.

Then, the lid 7 is the tension coil spring 12 described above.
The disc tray 5 is biased in the direction of being pulled out from the housing 2 by being biased in the opening direction.

The disc tray 5 is prevented from being biased in the pull-out direction by the lock means 18 provided in the housing 2 in the state of being housed in the housing 2.

That is, the lock means 18 is a lock lever 19 rotatably supported on the side portion of the housing 2, and a lock claw 20 formed on the lock lever 19 locks the disk tray 5 side. It comprises a pin 21 and a lock spring 22 for urging the lock lever 19 in the locking direction. The lock pin 21 is located at a position where the lock claw 20 is locked when the disc tray 5 is housed in the housing 2. It is provided.

The front end edge of the lock claw 20 is an inclined edge 20a which is biased downward as it goes forward, whereby the disc tray 5 is slid in the storage direction from the unlocked state, and the lock pin 21 is locked. When the lock lever 19 collides with the inclined edge 20a of the lock lever 20, the lock lever 19 pivots downward and the lock pin 21 rides over the lock claw 20.

When the lock pin 21 gets over the lock claw 20, the lock lever 19 is rotated by the lock spring 22 to lock the lock pin 21 on the lock claw 20 so that the disc tray 5 is locked. It has become.

Further, the front end of the lock lever 19 projects slightly forward from the housing front plate 10, and the operator can operate the projected part to unlock the disc tray 5. There is.

Thus, when the lock lever 19 is operated to unlock the disc tray 5 with the lid 7 closing the loading opening 6, that is, with the disc tray 5 housed in the housing 2, The tension coil spring 12 causes the lid 7 to slide in the opening direction, and the disc tray 5 is pulled out via the interlocking gear 17.

With the lid 7 having the loading opening 6 open, approximately half the diameter D of the CD 3 is pulled out of the disc tray 5 from the housing 2, whereby the opening of the loading opening 6 and the disc tray 5 are opened. With the amount of withdrawal, the diameter D of the CD 3 is released, and the CD 3 can be easily mounted on the disk mounting portion 4.

When the disc tray 5 is artificially pushed in the storing direction, the disc tray 5 is slid in the storing direction and the lid 7 is closed in the closing direction against the elastic force of the tension coil spring 12. Therefore, the lid 7 closes the loading opening 6, the disc tray 5 is housed in the housing 2, and, as described above, the lock pin 21 goes over the inclined edge 20a of the lock claw 20 and the disc tray 5 is closed. Is locked.

As described above, in order to mount the CD 3 on the disk mounting portion 4, the disk tray 5 is set to the diameter D of the CD 3.
Is possible with almost half of
Even if there is relatively little space around the D player 1, C
It becomes possible to load D3.

The pitch of the two racks 15 and 16 may be changed. To do this, the interlocking gear 17
Can be realized by attaching two spur gears having different pitches and attaching the racks 15 and 16 matching the respective pitches to the disc tray 5 and the lid 7.
Then, by doing so, the sliding amount of the lid body 7 and the sliding amount of the disc tray 5 can be made different.

The reverse slide means 8 may be provided on both the left and right sides of the lid 7 and the disc tray 5, or may be provided on one side. For example, when the reverse slide means 8 is provided on one side, it is preferable to provide left and right slide synchronizing means on the lid 7 and the disc tray 5, respectively. In this way, when the lid 7 and the disc tray 5 are slid. It is possible to prevent the occurrence of prying. As the left-right slide synchronizing means, for example, it is considered that flat gears are attached to both ends of a support shaft extending in the left-right direction, and racks meshing with the flat gears are provided on both left and right side surfaces of the lid 7 or the disc tray 5. (Illustration is omitted).

The CD according to the first embodiment
In the player 1, the tension coil spring 12 that biases the lid body 7 in the opening direction is used to open the lid body 7 and pull out the disc tray 5, so that another driving means is not required and the player 1 is simple. The structure may be, but is not limited to this, and the lid 7 and the disc tray 5 are driven by a motor.
You may make it slide.

7 to 9 show a modified example 1A of the CD player according to the first embodiment, in which the lid is flush with the top plate of the housing when the loading opening 6 is closed. It is the one. Therefore, in the following description, the part different from the first embodiment will be mainly described.
The description of the other parts will be omitted by giving the same reference numerals to the same parts in the CD player according to the first embodiment described above.

7 and 8, the details of the disc tray 5 and the CD mechanical deck 13 are omitted, and the disc tray 5 is shown as a box.

The front end edge of the top plate 9A of the housing forming the loading opening 6 is tapered toward the rear as it goes downward.
Is formed in.

The rear end edge of the lid 7A is formed with a tapered surface 24 which is displaced rearward as it goes downward, and the inclination angles of the two tapered surfaces 23, 24 are substantially the same.

The lid 7A is flush with the housing top plate 9A when the loading opening 6 is closed, and slides under the housing top plate 9A when the loading opening 6 is opened. ing.

Concretely, guide members 25, 25 are respectively disposed so as to face the left and right side edges of the lid 7A, and the lid 7 is provided in two front and rear guide grooves 26, 26 formed in the guide member 25.
Guide pins 27, 27 projectingly provided on the left and right side edges of A are slidably fitted, and each of the guide grooves 26 is an inclined groove 26a which is biased downward as the front side portion thereof goes rearward.
And a horizontal groove 26 extending rearward from the rear end of the inclined groove 26a.
b is formed. The inclination angle of the inclined groove 26a is the taper surface 23 formed on the front edge of the housing top plate 9A.
The inclination angle of the tapered surface 24 formed at the rear end edge of the lid 7A is substantially the same.

The lid 7A is positioned so as to sneak into the lower side of the top plate 9A of the housing when the loading opening 6 is opened, and slides in the closing direction so that the lid 7A closes the loading opening 6. Immediately before the operation, the guided pins 27, 27 are biased upward along the inclined grooves 26a, 26a, so that when the loading opening 6 is closed, the lid 7A is flush with the housing top plate 9A. Has become.

In the rack 28 on the lid side, vertically elongated holes 29, 29 are formed at the positions corresponding to the two guided pins 27, 27.
And the guided pin 2 is formed in the long holes 29, 29, respectively.
7 and 27 are individually penetrated, and the lid side rack 28 is disposed between the lid 7A and the guide member 25.

Further, horizontally extending restricting grooves 30, 30 are formed below the guide groove 26 of the guide member 25, and the guide member is provided on the lid side rack 28 below the elongated holes 29, 29. Projecting pins 31 and 31 projecting toward the 25 side are formed, respectively, and these projecting pins 31 and 31 are slidably fitted in the above-mentioned restriction grooves 30 and 30 of the guide member 25.

As a result, the lid side rack 28 becomes the lid 7
While moving in the front-back direction together with A, the guide member 25
It is designed to move only in the horizontal direction by being restricted by the restriction grooves 30, 30.

When the lid 7A closes the loading opening 6, the guided pins 27, 27 of the lid 7A among the guide grooves 26, 26 of the guide member 25 have inclined grooves 26a, 26a.
At the front end of a, the lid 7A is biased upward, and the lid 7A and the housing top plate 9A are flush with each other.

In the closed state of the lid 7A, the taper surface 24 at the rear edge of the lid 7A is positioned so as to be aligned with the taper surface 23 at the front edge of the top plate 9A of the housing. Since the gap between the tapered surfaces 23 and 24 is small, dust or the like does not enter the housing 2 through the gap.

When the lid 7A is slid in the opening direction,
The guided pins 27, 27 of the lid 7A move rearward along the inclined grooves 26a, 26a of the guide member 25 while being displaced downward. At this time, the inclination angle between the tapered surface 23 formed on the front edge of the housing top plate 9A and the tapered surface 24 formed on the rear edge of the lid 7A is formed to be substantially the same as the inclination angle of the inclined groove. The lid 7A is smoothly displaced downward without the tapered surfaces 23 and 24 interfering with each other.

Since the guided pins 27, 27 retreat in the horizontal direction after reaching the horizontal grooves 26b, 26b, the lid 7A is positioned so as to go under the housing top plate 9A. .

Further, the guided pins 27, 27 of the lid 7A are fitted in the vertically long holes 29, 29 of the lid side rack 28, and the projecting pins 31, 31 of the lid side rack 28 are of the guide member 25. Since it fits in the regulation grooves 30, 30, the lid 7A
Even if it is biased in the vertical direction following the guide grooves 26, 26, the lid side rack 28 slides only in the horizontal direction,
Therefore, even if the lid 7A moves in the vertical direction, the engagement between the lid-side rack 28 and the interlocking gear 17 does not occur.

When the lid 7A opens the loading opening 6, the lid 7A is in a state of being housed below the housing top plate 9A.

Although the description is omitted, as the lid 7A slides, the interlocking gear 17 is rotated to move the tray side rack 15 and slide the disc tray 5 in the opposite direction to the lid 7A. This is similar to that according to the first embodiment.

Further, the guide grooves 26, 26 are preferably symmetrical in the left and right guide members 25, 25,
Two front and rear guide grooves 2 in which one guide member 25 is formed
6, 26 do not necessarily have the same shape. By devising the shape of the front and rear guide grooves 26, 26, for example, when the lid 7A slides in the opening direction from the closed state, only the rear side edge of the lid 7A is initially in the housing top plate at the initial stage. It is also possible that the front side edge of the lid body 7A is gradually displaced downward as the plate thickness of 9A lowers and slides backward.

FIGS. 10 to 13 show a second embodiment of the disk drive device of the present invention, and the second embodiment is different from the first embodiment. Since only the reverse slide means is shown, only the essential parts are shown in the drawings, and the description will be made only on the above-mentioned differences, and the other parts will be referred to by the first parts in the respective parts of the drawings.
The description thereof will be omitted by giving the same reference numerals to the similar portions in the CD player according to the embodiment.

The reverse slide means 32 of the CD player 1B is provided with a rotating arm 33 which is horizontally rotatable with respect to the housing 2 and which is long in the left-right direction, and one end of the rotating arm 33. The lid-side connecting pin 34 protrudingly provided and the tray-side connecting pin 3 protrudingly provided at the other end of the rotating arm 33.
5 and.

Specifically, the lid-side connecting pin 34 projecting from one end of the rotating arm 33 is a long hole formed in the left-right direction of the lid 7B and approximately in the center in the front-rear direction and slightly longer in the left-right direction. The tray-side connecting pin 35 fitted to the rotary arm 33 and fitted to the rotary arm 33 is formed on the right side of the disc tray 5 and at a position close to the front side by about 1/3 from the rear side edge. It is fitted in the elongated hole 37 that is slightly longer in the left-right direction.

Further, the rotating arm 33 is rotatably supported at substantially the center thereof and is positioned so as to extend substantially in the left-right direction.

The elongated hole 36 formed in the lid 7B may pass through the lid 7B, but may have a flat concave shape that opens downward. With such a flat concave portion, a through hole is not formed in the lid 7B, and
It is possible to prevent dust and the like from entering the housing 2 (not shown).

When the lid 7B is slid,
The rotating arm 33 is to be rotated, so that
The disc tray 5 can be slid in the direction opposite to the lid body 7B, and almost half of the diameter D of the CD 3 can be moved to the housing 2 as in the CD player 1 described in the first embodiment.
The CD player 1B can be used even in a relatively narrow space because the space for mounting the CD 3 on the disc mounting portion 4 can be sufficiently widened only by pulling it out from.

As for the relationship between the connecting pin and the elongated hole, the rotating arm 33 may be formed with the elongated hole, and the connecting pin may be projected on the lid 7B and the disc tray 5.

Further, in the above-described embodiment, the center of rotation of the rotating arm 33 is substantially the central portion in the length direction thereof, but the present invention is not limited to this, and the position centered in any direction is used as the center of rotation. As a result, the sliding amounts of the lid 7B and the disc tray 5 can be made different.

FIGS. 14 to 16 show a third embodiment of the disk drive device of the present invention. This third embodiment is different from the first and second embodiments. The difference is that only the disc tray is pulled out without including the CD mechanical deck in the drawer. Here, the CD mechanical deck includes a CD rotating mechanism and a signal reading mechanism, and corresponds to the "disk drive mechanism" described in claim 4 of the claims.

Therefore, C according to the third embodiment
For the D player 1C, in order to pull out only the disc tray from the housing, a retracting mechanism for retracting the CD mechanical deck from the movement range of the disc tray when pulling out is essential. In the following description, the mechanical deck retracting mechanism will be mainly described. The description of other parts will be omitted by assigning the same reference numerals to the same parts in the CD player 1 according to the first embodiment described above, and the description of the other parts will be omitted. The disk tray slide mechanism is also omitted.

As is apparent from what has been described above, the disk drive device of the present invention includes a housing having a main face plate with a loading opening for inserting and removing a disk-shaped recording medium, and the housing. There are a lid body that slides in relation to open and close the loading opening, a disc tray that holds the disc-shaped recording medium and slides with respect to the housing, and a sliding direction of the lid body and a sliding direction of the disc tray. A reverse slide means for moving the lid and the disc tray in opposite directions, the loading opening and the disc mounting portion of the disc tray face each other, and when the lid is opened, the disc is opened. The total amount of the tray withdrawal amount and the loading opening amount is set to be substantially the same as the diameter of the disc-shaped recording medium.

Therefore, in the disk drive device of the present invention, when the disk-shaped recording medium is loaded into the disk drive device, the lid does not rotate above the housing, and the disk drive device protrudes from the main surface. Since the size of the disk tray used is about half the diameter of the disk-shaped recording medium, it can be used in a relatively narrow space of the disk drive device.

According to the second aspect of the invention, the reverse slide means comprises two racks facing each other and an interlocking gear meshing with the racks. One of the racks is connected to the lid, and the other rack is connected. Since the rack is connected to the disc tray, the lid and the disc tray can be slid in the opposite direction with a simple structure.

According to the third aspect of the present invention, the lid body is substantially flush with the main face plate of the housing when closed, and sunk into the back side of the main face plate of the housing when opened. Therefore, when the lid is closed, the main surface of the housing has no irregularities, and a clean design can be achieved.

According to the invention described in claim 4, since the disc drive mechanism is slid together with the slide of the disc tray, it is necessary to provide a mechanism for retracting the CD mechanical deck from the disc tray when the disc tray is pulled out. Instead, the mechanism can be simplified accordingly.
