Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention is a disc player that is most suitable for application to, for example, a compact disc player. The present invention relates to a disc player configured such that the tray is drawn into the player body through the opening provided in the player body, and then the disc is horizontally mounted on a turntable disposed within the player body.

[Background technology and its problems]

As is well known, compact discs used in compact disc players are capable of long-time playback despite their very small diameter of 12 cm. Therefore, compact disc players are suitable for outdoor use and car stereo applications, and compact disc players have recently been made much thinner and smaller.

However, in order to make the horizontal loading type compact disk player thinner and smaller, the compact disk is placed on a disk tray and pulled horizontally into the player body from the front opening of the player body. things become a problem.

That is, first, as the depth dimension of the player main body is reduced, the amount by which the disk tray can be pulled out from the front opening to the outside of the player main body is limited. As a result, the compact disc placed on the disc tray cannot be pulled out so that its entire diameter is exposed outside the player body through the front opening. A portion of the disk remains inserted into the player body through the front opening. Next, as the height dimension of the player body has been reduced, the vertical dimension of the front opening has been restricted, and the gap between the disk on the disc tray and the upper edge of the front opening of the player body has become extremely small. Put it away.

As a result of the above, when setting a compact disc horizontally on the disc tray before loading, and when resetting the compact disc from the disc tray after ejecting, it is extremely difficult to attach or remove the compact disc from the disc tray. Part of the compact disk must be inserted and removed diagonally through a small gap, making it extremely inconvenient to attach and detach the disk.
Moreover, it is necessary to be very careful when inserting or removing the compact disk diagonally. There is a risk of damaging the disk.

[Purpose of the invention]

The present invention was devised in view of the above-mentioned circumstances, and it is an object of the present invention to provide a player that allows the operation of attaching and detaching a disk to and from a disk tray to be extremely easy, and also allows the depth dimension of the player body to be extremely small. It is something to do.

[Summary of the invention]

The present invention provides, in the horizontal loading type disk player described above, a tray carrier configured to support the disk tray and to be able to move in and out of the player body from the front opening in a horizontal direction, and to move the disk tray to the tray carrier. a diagonal elevating mechanism for moving the disc tray diagonally upward and downward in parallel so as to rise in the retracting direction; when the disk tray is pulled out of the player body from the front opening, the diagonal elevating mechanism The disk player is configured to move the disk tray downward in parallel in response to the pull-out operation of the disk tray.

According to the present invention configured in this manner, when the disk tray is pulled out of the player body from the front opening by the tray carrier, the disk tray is moved in parallel downward in accordance with the pull-out operation of the disk tray. The gap between the disk placed on the disk tray and the upper edge of the front opening of the player body is greatly expanded downward,
The operation of attaching and detaching the disk to and from the disk tray can be performed extremely easily. Moreover, the disk tray can be pulled out to the maximum extent possible while keeping the amount of the tray carrier pulled out to the outside of the player body relatively small, and the depth dimension of the player body can be made extremely small.

As is well known, the optical pickup device 69 includes an objective lens 70 and a two-axis drive device 71 for focusing a laser beam onto the recording track on the lower surface of the disk 1, and a pair of parallel guide axes. 72 and is configured to be horizontally moved in the radial direction of the disk 1 (in the direction of arrow g). However, at this time, the optical pickup device 69 is placed at an angle θ ₁ of approximately 45° with respect to the side wall 36b and rear wall 57 of the player body 3.
The disk 1 is configured to be horizontally moved in the radial direction (direction of arrow g) along a reference line _P1 inclined at . As a result, when the objective lens 70 is moved to the outermost recording track position of the disk 1, the optical pickup device 69 is moved to the side wall 36.
By moving the optical pickup device 69 to the corner portion 73 between the optical pickup device 69 and the rear wall 57, the depth _l1 of the player body 3 is prevented from increasing due to the dead space occupied by the optical pickup device 69.

Next, the loading operation of the disk 1 will be explained.

First, as shown in FIG. 6A, before the loading operation is started, the tray carrier 6 is pulled out from the front opening 4 to the outside of the player main body 3 by a predetermined pullout amount l ₂ horizontally in the direction of arrow b. Then, the disk tray 5 on the tray carrier 6 is translated (lowered) parallel to the respective inclined guides 18 with respect to the tray carrier 6 diagonally downward (in the direction of the arrow i) toward the drawing direction (the direction of the arrow b). There is. However, the entire disc tray 5 cannot be pulled out of the player body 3, and the rear end 5a of the disc tray 5 remains inserted into the player body ₃ by a length of l3. Before starting this loading operation, as shown in FIGS. 6A and 10A, the upper part of the pinion 26 is engaged with the upper end 19a of the inclined rack 19, and the lower part of the pinion 26 is at the front end position of the horizontal rack 46. is engaged with. Further, as shown in FIG. 6A, each guide pin 25 has an upper end 18a of each inclined guide 18.
has been moved to. Further, as shown in FIG. 7, the spring 43 is stretched, and the rear end support portion 75 of the horizontal guide shaft 27 of the tray carrier 6 is brought into contact with the rear surface of the horizontal guide bearing 34, so that the tray carrier 6
The drawer position is regulated.

Then, as shown by the solid line in FIG. 5A, the disk 1 is inserted into the recess 15 of the disk tray 5 and positioned horizontally on the bottom surface 15a thereof. In this case, as shown by the dashed line in FIG. 5A, a part of the disk 1 is inserted diagonally downward from the direction of arrow j into the player body 3 through the front opening 4, and then the disk 1 is inserted in the direction of arrow k. It is horizontally inserted into the recess 15 by rotating it.

As described above, after setting the disk 1 horizontally on the disk tray 5, when the loading eject switch 7 shown in FIG. 1 is turned on, the motor 38 is driven to rotate in the forward direction as shown in FIG. 3A. , a pinion 40 is rotationally driven in the direction of arrow m by the motor 38 via the worm gear 39. Then, the tray carrier 6 is driven in the direction of arrow a via the horizontal rack 28, and the horizontal guide shaft 2
7 and the horizontal guide rail 35, the tray carrier 6 is pulled in horizontally in the direction of arrow a as shown in FIGS. 5B and 6B.

However, at this time, while the tray carrier 6 is horizontally moved from the pull-out position shown in FIG. _6A to the position shown in FIG. In parallel with each inclined guide 18, diagonally upward (direction of arrow n) toward its retraction direction (direction of arrow a).
is translated (raised) to That is, as the tray carrier 6 moves horizontally in the direction of the arrow a, the 10th A
As shown in the figure and FIG. 10B, the pinion 26 rolls on a fixed horizontal rack 28, and is advanced in the direction of arrow a while being rotated in the direction of arrow o. Then, the inclined track 19 is driven in the direction of arrow n by the rotational force of pinion 26 in the direction of arrow o, and the disk tray 5 is pulled in the direction of arrow a against the tray carrier 6 by the force of the spring 43 shown in FIG. Due to the cooperative action, the disk tray 5 is translated (raised) diagonally upward (in the direction of arrow n) relative to the tray carrier 6, as shown by the solid line in FIG. 6B. As shown in FIG. 6B, by parallel movement of the disk tray 5 in the direction of arrow n, each guide pin 25 is moved to the lower end 18b of each inclined guide 18, and the upper part of the pinion 26 is moved to the lower end 19b of the inclined rack 19. will be moved to. Then, as the tray carrier 6 continues to be horizontally retracted in the direction of arrow a, the lower part of the pinion 26 is separated from the horizontal rack 46 as shown in FIG. 6B.

As the disk tray 5 is translated (raised) in the direction of the arrow n, the rear end 5b of the disk tray 5 is moved a predetermined length l in the direction of the arrow a from the rear end 6a of the tray carrier 6, as shown in FIG. 6B. ₅ , the disk tray 5 is raised upward from the upper surface 6b of the tray carrier 6 to a predetermined height _h2 , as shown in FIGS. 4A and 5B. As a result, the disk 1 on the disk tray 5 is raised to an intermediate position between the turntable 51 and the clamper 54, as shown in FIG. 5B.

As the tray carrier 6 is subsequently pulled in horizontally in the direction of arrow a, the disk 1
is drawn horizontally between the turntable 51 and the clamper 54. And as shown in Figure 5C,
When the disk 1 is pulled in horizontally in the direction of arrow a until the center of the center hole 1a of the disk 1 coincides with the center of the center pin 51a of the turntable 51, the rear end of the disk tray 5 as shown in FIG. 6C. The portion 5a comes into contact with the rear wall 57 of the player main body 3, and the disc tray 5 is stopped at that position.

Even after the disk tray 5 has stopped, the tray carrier 6 is continuously retracted horizontally in the direction of arrow a by a predetermined length _l5 shown in FIG. 6C to the position shown in FIG. 6D. At this time, as shown in FIG. 6D, each guide pin 25 is connected to each inclined guide 1.
The disk tray 5 is moved to the upper end 18a of the disk tray 5.
is vertically translated (downward) in the direction of arrow q.
That is, at this time, as the tray carrier 6 moves in the direction of arrow a, the disk tray 5 is translated diagonally downward (in the direction of arrow i) in the opposite direction to the direction of arrow a with respect to the tray carrier 6. Therefore, in reality, the moving component of the tray carrier 6 in the opposite direction to the arrow a direction is the arrow a of the tray carrier 6.
This is canceled by the movement component in the direction, and the disk tray 5 is translated (downward) perpendicularly to the direction of the arrow q. Note that at this time, the spring 43 shown in FIG. 7 is stretched again.

By this parallel movement (downward) of the disk tray 5 in the direction of the arrow q, the disk 1 on the disk tray 5 is lowered and mounted horizontally on the turntable 51, as shown in FIGS. 4B and 5D. , the center hole 1a of the disk 1 is engaged with the center pin 51a of the turntable 51. In addition, at this time, just before the disk tray 5 reaches the lowest position, the disk 1 is moved to the turntable 51.
As shown in FIG. 5D, when the disk tray 5 reaches the lowest position, the disk 1 is attached to the bottom surface 15 of the recess 15 of the disk tray 5.
The disk 1 is lifted up by a predetermined height _h3 above point a, and the disk 1 is free to rotate.

As a result, the tray carrier 6 is completely drawn into the player body 3, as shown in FIG. 5D.
A front opening 4 of the player body 3 is closed by a lid 22 at the front end of the tray carrier 6.

On the other hand, at this time, while the tray carrier 6 is being pulled in horizontally in the direction of the arrow a for a predetermined length l ₅ minutes from the position shown in FIG. 6C, the pins of the tray carrier 6 are 47 comes into contact with the lower end 61b of the control plate 61, and the pin 47 pushes the control plate 61 in the direction of arrow a to the position shown by the dashed line in FIG. Then, as shown by the one-dot chain line in FIG. is lowered. Then, as shown in FIG. 5D, the clamper 5
4 presses the disk 1 from above with the force of the spring 59, and pushes the disk 1 onto the turntable 51.
Fix it on top.

As described above, the loading operation of the disk 1 is completed, the retracting completion position of the tray carrier 6 shown in FIG. 6D is detected by a sensor (not shown), the motor 38 is stopped, and the tray carrier 6 is It is stopped at the completion position. As shown in FIG. 3B, the tray carrier 6 remains locked at the above-mentioned stop position due to the self-locking function of the worm and worm wheel of the worm gear 39 interposed in the deceleration drive mechanism of the pinion 40 by the motor 38.

Next, after the loading operation of the disk 1 as described above is completed, when the playback/pause switch 8 etc. shown in FIG. At the same time, the optical pickup device 69 is controlled to move in the radial direction of the disk 1 (in the direction of arrow g), as shown in FIG. Disk 1 is
The desired reading and reproduction of the data will be performed.

Next, the ejecting operation of the disk 1 will be explained.

When the loading eject switch 7 shown in FIG. 1 is turned on after the desired playback of the disk 1, the motor 38 is driven to rotate in the reverse direction as shown in FIG. Pinion 40 is rotationally driven in the direction of arrow c. Then, the tray carrier rear 6 is pulled out horizontally in the direction of arrow b by a reverse operation during loading.

That is, the ejecting operation is a reverse operation of the loading operation, and first, the tray carrier 6
While being pulled out horizontally by a predetermined length _l5 in the direction of arrow b from the position shown in Figure D to the position shown in Figure 6C, the pin 47 of the tray carrier 6 is pulled out as shown by the solid line in Figure 9. The control plate 61 is removed from the lower end 61b in the direction of arrow b. Then, the control plate 61 is rotated in the direction of arrow e by the spring 66, and both the protrusions 6
2 and 63, the lifting arm 55 is rotated in the direction of arrow f against the spring 59, and the clamper 54 is raised to the position shown in FIG. 5C. .

During this time, as shown in FIG. 6C, the disk tray 5 is translated (raised) in the direction of arrow t by the force of the spring 43 shown in FIG. 7, and the disk 1 is moved up as shown in FIG. 5C. The disk tray 5 is then accommodated again in the recess 15 of the disk tray 5 and lifted above the turntable 51.

Next, the tray carrier 6 is pulled out horizontally in the direction of arrow b from the position shown in FIG. 6C to the pull-out position shown in FIG. It is pulled out horizontally to a pulled out position outside the player main body 3 shown in FIG. 5A.

However, at this time, after the tray carrier 6 is pulled out horizontally in the direction of arrow b to the position shown in FIG. 6B, the lower part of the pinion 26 is moved to the rear end position of the fixed horizontal rack 46, as shown in FIG. 10B. engaged. 10A and 10B while the tray carrier 6 is horizontally pulled out for a predetermined distance _l4 minutes in the direction of arrow b from the position shown in FIG. 6B to the pulled out position shown in FIG. 6A. As shown in the figure, it rolls on the horizontal rack 46 and
It moves in the direction of arrow b while being rotated in the direction of arrow b.

At this time, contrary to the loading process, the tilting rack 19 is driven in the direction of arrow i by the rotational force of the pinion 26, and as shown in FIG. 18, and is moved diagonally downward (in the direction of arrow i) toward the drawing direction (direction of arrow b). At this time, the spring 43 shown in FIG. 7 is stretched again.

As a result, the ejecting operation of the disk 1 is completed, and the tray carrier 6 is brought into contact with the rear surface of the horizontal guide bearing 34 by the rear end support portion 75 of the horizontal guide shaft 27 and stopped as shown in FIG. The position at which the tray carrier 6 has been completely drawn out is detected by a sensor (not shown), and the motor 38
will be stopped.

In summary, in this disk player 2, as shown in FIG. 5A, when the disk 1 is pulled out horizontally from the front opening 4 to the pull-out position outside the player main body 3 using the disk tray 5 in the direction of arrow b, As shown in FIG. 6A, immediately before the tray carrier 6 is pulled out horizontally from the direction of arrow b to the drawing completion position and stopped, the disk tray 5 is moved diagonally toward the drawing direction (direction of arrow b) with respect to the tray carrier 6. It is configured to move parallelly (descend) downward (in the direction of arrow i).

Therefore, when the ejection of the disk 1 is completed, as shown in FIG. 5A, the bottom surface 15a of the recess 15, which is the disk mounting surface on the disk tray 5, is
It is pulled down to a sufficiently low position with respect to the upper edge 4a of the front opening 4 of the player main body 3, and the bottom surface 1
The vertical dimension _h4 of the gap 76 between 5a and the upper edge 4a is sufficiently enlarged downwardly. As a result,
After ejecting this disk 1, 1 is shown in Figure 5A.
As shown by the dotted chain line, the maximum rotation angle θ ₂ of the disk 1 when the disk 1 on the disk tray 5 is rotated in the direction of arrow v and then reset to be pulled out obliquely upward in the direction of arrow w. can be taken very large. This makes it extremely easy to attach and detach the disk 1 to and from the disk tray 5 when setting the disk 1 horizontally on the disk tray 5 prior to loading and when resetting the disk 1 from the disk tray 5 after ejection. I can do it.

In addition, as shown in FIG. 6A, the disk tray 5
By configuring the player body 3 to be moved in parallel in the direction of arrow i, which is an obliquely downward direction, while advancing in the direction of arrow b, which is the direction in which the player main body 3 is pulled out,
The disk tray 5 can be pulled out to the maximum extent outside the player main body 3 while keeping the amount l ₂ of the tray carrier 6 pulled out to the outside relatively small. As a result, the disk tray 5 and tray carrier 6
The total length dimension _l6 can be made extremely small,
The depth dimension _l1 of the player body 3 has been successfully reduced to around 13 cm, which is very close to the diameter of the disc 1 (12 cm).

Next, a second embodiment of the loading and ejecting mechanism for the disk 1 will be described with reference to FIGS. 11A and 11B.

In this case, the disk tray 5 is mounted on the tray carrier 6 using a pair of left and right parallel quadruple link mechanisms so that it can be raised and lowered in the diagonal up and down directions (directions of arrows i and n). That is, the lower ends of the left and right pairs of parallel links 78a, 78b are rotatably supported on the left and right side plates 24a, 24b of the tray carrier 6 via fulcrum pins 79a, 79b, respectively.
The upper ends of each pair of parallel links 78a, 78b are the left and right side plates 17a, 17b of the disk tray 5.
are rotatably supported via fulcrum pins 80a and 80b, respectively. and one parallel link 78
Each pair of parallel links 78a, 78b is moved by the force of the spring 83, which is bridged between the spring locking portion 81 provided on the left and right side plates 24a, 24b of the tray carrier 6. 1st
In Figure 1A, it is rotated in the direction of the arrow x. An arm 84 extending downward from the fulcrum pin 79a is integrally provided on one of the parallel links 78a, and as shown in FIG. 11A, this arm 84 hits a stopper 85 provided on the left and right side plates 24a. This contact restricts rotation in the direction of arrow x.

Therefore, in this case, when the tray carrier rear 6 is pulled out horizontally from the front opening 4 to the outside of the player body 3 in the direction of arrow b, as shown in FIG. Each pair of parallel links 7 by a force of 83
8a and 78b are rotated in the direction of the arrow x, and the disk tray 5 is moved diagonally upward (in the direction of the arrow n) relative to the tray carrier 6 in parallel (raised) to a predetermined height _h2 . and then pulled out horizontally.

Immediately before the tray carrier 6 reaches the draw-out completion position shown in FIG. Each pair of parallel links 78
a, 78b are rotated in the direction of arrow y as shown in FIG. 11B. As a result, as shown in Figure 11B,
Immediately before the tray carrier 6 reaches the drawing completion position, the disk tray 5 is moved diagonally downward (parallel to the arrow i direction) relative to the tray carrier 6 in the drawing direction (arrow b direction). 5 in the direction of arrow i, the vertical dimension h ₄ of the above-mentioned gap 76 is greatly expanded as shown in FIG. 11B.

Although the embodiments of the present invention have been described above, the present invention is not limited to the embodiments, and various effective changes can be made based on the technical idea of the present invention.

[Application example]

The present invention is applicable not only to compact disc players but also to various disc players that use various audio discs and video discs.

〔Effect of the invention〕

As described above, when ejecting a disk, when the disk tray is pulled out of the player body from the front opening by the tray carrier, the disk tray is moved in parallel downward in accordance with the disk tray pull-out operation. ,
The gap between the disk placed on the disk tray and the upper edge of the front opening of the player main body can be greatly expanded downward. Therefore, as the disk player has become much thinner and smaller, the amount that the disk tray can be pulled out of the player body is limited, and the disk can be pulled out to a state where its entire diameter is exposed outside the player body through the front opening. Even if the gap between the disk on the disk tray and the upper edge of the front opening of the player body becomes very small, the vertical dimensions of the front opening are restricted. The operation of attaching and detaching the disk to and from the disk tray can be carried out extremely easily by utilizing the gap greatly enlarged downward as described above. As a result, it is possible to further reduce the thickness and size of the disk player.

Furthermore, according to the present invention, when the disk tray supported by the tray carrier is pulled out of the player body from the front opening, the disk tray is moved diagonally downward in parallel with respect to the tray carrier in the drawing direction. With this structure, the disk tray can be pulled out to the maximum extent possible while keeping the amount of the tray carrier pulled out to the outside of the player body relatively small. Therefore, the overall length of the tray carrier can be made extremely small, and the depth of the player body into which the tray carrier is horizontally inserted can be made extremely small.
