Abstract

PURPOSE:To reduce the draw-out amount of a tray carrier and to reduce extremely the depth of a player main body through which the tray carrier is inserted horizontally, by shifting a disk tray in parallel in the obliquely lower direction when it is pulled out of the player main body. CONSTITUTION:A disk tray 5 is moving in the obliquely lower direction (an arrow i) and in parallel to a sloping guide 18 against a tray carrier 6 while the carrier 6 is drawn outside a player main body 3 through a front opening 4. The tray 5 can be pulled at maximum outside the main body 3 while reducing the pull-out amount l2 of the carrier 6 in a comparatively small range. Thus it is possible to reduce extremely the total length l6 of both the tray 5 and the carrier 6. Furthermore the depth l1 of the main body 3 can be reduced down to about 12cm which is extremely approximate to the diameter (12cm) of a disk 1.

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. After the disc tray is pulled horizontally into the player main body through a front opening provided in the player main body, the disc tray is moved downward in parallel to place the disc horizontally on the turntable. This invention relates to a disc player.

[Background technology and its problems]

As is well known, compact discs used in compact disc players can be played for a long time even though they have a very small diameter of 121 mm. Therefore, compact disc players are suitable for outdoor use and car stereo applications, and compact disc players have recently become much thinner and smaller.

However, in order to make the horizontal loading compact disc player thinner and smaller, the compact disc is placed on a disc tray and pulled horizontally into the player body from the front opening of the player body. This is just a glimpse.

That is, first, as the depth dimension of the player body is reduced, the amount by which the disc tray can be pulled out of the player body from the front opening 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, and even if the disc tray is pulled out of the player body all at once, A portion of the compact disc remains inserted into the player body through the front opening. Next, as the dimensions of the player body have been reduced, the vertical dimensions of the front opening have become limited, and the gap between the disc on the disc tray and the upper edge of the front opening of the player body has become very small. turn into.

As a result of the above, when loading and unloading a compact disc onto the disc tray, when setting the compact disc horizontally on the disc tray before loading, and when resetting the compact disc from the disc tray after ejecting, Part of the compact disc must be inserted and removed diagonally through a very small gap, making it extremely inconvenient to insert and remove the disc.

Moreover, it is necessary to be very careful when inserting and removing the compact disc diagonally.If the compact disc is rubbed strongly against the upper edge of the front opening or on the disc tray while being inserted or removed diagonally, There is a risk that the compact disc may be damaged.

[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 can extremely easily attach and detach a disc onto and from a disc tray, and furthermore, can extremely reduce the depth dimension of the player body. It is something to do.

[Summary of the invention]

The present invention provides a tray carrier configured to be horizontally movable from a front opening provided in a player main body, a disc tray placed on the tray carrier, and a disc tray placed on the tray carrier. and a diagonal lifting mechanism for moving the disc horizontally in parallel in the vertical direction, and when the tray carrier is horizontally pulled into the player main body with a disc placed horizontally on the disc tray, the disc tray is moved horizontally into the player body. The disc is configured to be placed on a turntable by moving the disc downward in parallel,
i* A disc player configured such that when the tray carrier is pulled out horizontally from the front opening to the outside of the player main body, the disc tray is moved diagonally downward parallel to the tray carrier in the same direction as the tray carrier is pulled out. It is.

According to the present invention constructed in this way, when the disc tray is pulled out horizontally from the front opening to the outside of the player main body by the tray carrier, the disc g on the disc tray 7 and above the front opening of the player main body are removed. By greatly expanding the gap between the disk and the edge downward, it is possible to extremely easily attach and detach the disk onto and from the disk tray. Moreover, the disc tray can be pulled out to the maximum extent possible while keeping the drawer lid of the tray carrier out of the player body relatively small, and the depth dimension of the player body can be made extremely small.

A stopper 671ζ attached to the inner surface of the 1111-face wall 56a is abutted to restrict rotation in the direction of arrow e.

Next, as shown in FIGS. 6A and 6B, an optical pickup device 69 for reading and reproducing the disc 1 is disposed on one side of the rear end of the player body 6. As is well known, this optical pickup device @69 has an objective lens 70 and its two-axis drive device 71 for irradiating and focusing a laser beam onto the recording track on the lower surface of the disk 1, and a pair of parallel guides. It is guided by the shaft 72 and horizontally moved in the radial direction of the disk 1 (in the direction of arrow g).
It is configured so that However, at this time, the optical pickup device 69 is placed in the radial direction of the disc 1 (in the direction of arrow "g" ).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 horizontally to the corner of the side wall 36b and the rear wall 57. By moving the optical pickup device 69 to the portion 76, the dead space occupied by the optical pickup device 69 prevents the vertical dimension 11 of the player body 3 from increasing.

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

First, as shown in FIG. 6A, before the loading operation is started, the tray carrier 6 is pulled out of the player main body 6 from the front opening 4 by a predetermined pullout amount 12 horizontally in the direction of the arrow. Then, the disk tray 5 on the tray carrier 6 is translated (downward) diagonally downward (in the direction of the arrow i) toward the pull-out direction (in the direction of the arrow mark) in parallel with each inclined guide 1B with respect to the tray carrier 6. has been done.

However, the entire disc tray 5 cannot be pulled out of the player main body 6, and the rear end 5a of the disc tray 5 remains inserted into the player main body 3 by a length of 15 minutes. Before starting the p-ding operation, as shown in FIGS. 6A and 10A, the pinion 26
The upper part of the binion 26 is engaged with the upper end 19a' of the inclined rack 19, and the lower part of the binion 26 is engaged with the front end position of the horizontal rack 46. Further, as shown in FIG. 6A, each guide bin 25 has been moved to the upper end 113a of each inclined guide 18. Further, as shown in FIG. 7, the spring 43 is stretched, and the horizontal guide shaft 27 of the tray carrier 6
The rear end support portion 75 is brought into contact with the rear surface of the horizontal guide bearing 64, and the draw-out position of the tray carrier 6 is regulated.

Next, as shown by the solid line in FIG. 5A, the disc 1 is inserted into the recess 15 of the disc tray 5, and the bottom surface 15
a Set it so that it is positioned horizontally on top. In this case, as shown by the one-dot chain line in Fig. 5A, the disk 1
After inserting a portion of the disc 1 diagonally downward from the front opening 4 into the player body 6 in the direction of arrow j, the disc 1 is horizontally inserted into the recess 15 by rotating in the direction of the arrow.

As described above, the disk 1 is set horizontally on the disk tray 5, fCflk, and the loading process shown in FIG.
When the eject switch 7 is turned on, the motor 66 is rotated in the forward direction as shown in the sixth figure, and the pinion 40 is rotated in the direction of the arrow m by the seventh motor 6B via the worm gear 69.

Then, the tray carrier 6 is driven in the direction of arrow a via the horizontal rack 28, and the tray carrier 6 is moved to the fifth position while being guided by the horizontal guide shaft 27 and the horizontal guide rail 55.
As shown in Figures B and 6B, it is pulled in horizontally in the direction of arrow a.

However, at this time, while the tray carrier 6 is horizontally moved for a predetermined distance of 14 minutes in the direction of arrow a from the pull-out position shown in FIG. 6A to the position shown in FIG. It is parallelly moved (raised) in parallel with each of the inclined guides 18 and diagonally upward (in the direction of arrow n) in the same direction as the retraction direction (in the direction of arrow a). That is, as the tray carrier 6 moves horizontally in the direction of the arrow a, the 10th
As shown in Figures 1 and 10B, the pinion 26 rolls on a fixed horizontal rack 28 and advances in the direction of arrow a while being rotated in the same direction as arrow 0. Then the binion 2
The rotational force of 6 in the direction of the arrow O drives the inclined track 19 in the direction of the arrow n, and the rotational force of the spring 4 shown in FIG.
Due to the cooperative action of the pulling force of the disc tray 5 in the direction of the arrow a on the tray carrier 6 due to the force 6, the disc tray 5 is moved diagonally upward (arrow n direction) in parallel (
rise). As shown in FIG. 6B, by parallel movement of the disk tray 5 in the direction of arrow n, each guide bin 2
5 is moved to the lower end 16b of each IX 5% guide 18, and the upper part of the binion 26 is moved to the lower end 16b of the inclined rack 19.
Moved to 9b. And after this tray carrier 6
With the subsequent horizontal retraction in the direction of arrow a, the lower portion 85 of the pinion 26 is separated from the horizontal rack 46 as shown in FIG. 6B.

Then, 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 from the rear end 6a of the tray carrier 6 to the predetermined feldspar 15 in the direction of the arrow a, as shown in FIG. 6B. At the same time, as shown in FIGS. 4N and 5B, the disc tray 5 is lifted upward from the upper surface 6b of the tray carrier 6 to a certain height h2. 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.

Then, as the tray carrier 6 continues to be drawn horizontally in the direction of arrow a, the disk 1 is drawn horizontally between the turntable 51 and the clamper 54. As shown in FIG. 5C, the center hole 1a of the disk 1
When the disc 1 is pulled in horizontally in the direction of arrow a until the center of the center bin 51a of the turntable 51 coincides with the center of the center bin 51a of the turntable 51, the rear end 5a of the disc tray 5 touches the player body as shown in FIG. 6C. 6, the disc tray 5 comes to a stop at that position. Even after this disc tray 5 has stopped, the tray carrier 6 moves to the position shown in FIG. 6D as shown in FIG. 6C. Continue horizontally in the direction of arrow a for the predetermined length of 25 minutes.
Ru. At this time, as shown in FIG. 6D, each guide bin 25 is moved to the upper end 18a of each inclined guide 16, and due to the guiding action of the valley inclined guide 18 at that time, the disc tray 5 is perpendicularly parallel to the direction of arrow q. Moving (descending) makes me vomit.

That is, at this time, as the tray carrier 6 moves in the direction of the arrow a, the disk tray 5
, the tray carrier 6 is moved obliquely downward (direction of arrow i) in a direction opposite to the direction of the arrow a, and in reality, the movement component in the direction opposite to the direction of the arrow a is the movement component of the tray carrier 6. This is canceled by the movement component in the direction of arrow a, and the disk tray 5 is translated perpendicularly to the direction of arrow q (
(downward). Note that at this time, the spring 43 shown in FIG. 7 is stretched again.

By this parallel movement (downward) of the disc tray 5 in the direction of the arrow q, the disc 1 on the disc tray 5 is lowered and mounted horizontally on the turntable 51, as shown in FIGS. 4B and 5D. , the center hole 1a of the disc 1 or the center bin 51a of the turntable 51
is engaged with.

At this time, since the disc 1 is mounted on the turntable 51 just before the disc tray 5 reaches the lowest position, as shown in FIG. 5D, when the disc tray 5 reaches the lowest position, the disc 1 is lifted up by a predetermined height h3 above the bottom surface 15a of the recess 15 of the disk tray 5, and the disk 1 is free to rotate.

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

(The following margins are continued on the next page.) Meanwhile, at this time, while the tray carrier 6 is drawn in horizontally in the direction of arrow a for a predetermined length of 15 minutes from the position shown in FIG. 6C, as shown in FIG. As shown by the solid line in FIG. 9, the bin 47 of the tray carrier 6 comes into contact with the lower end 61b of the control plate 61, and the bin 47 pushes the control plate 61 in the direction of the arrow a to the position shown by the dashed line in FIG. . Then, as shown by the one-dot chain line in FIG.
The lift arm 55 is rotated by the spring 59 in the direction of the arrow d, and the clamper 54 is lowered.

As shown in FIG. 5D, the clamper 54 is connected to the spring 59.
The disk 1 is pressed from above by the force of 1, and the disk 1 is fixed on the turntable 51.

With the above steps, the loading operation of disk 1 is completed.
The retracting completion position of the tray carrier 6 shown in FIG. 6D is detected by a sensor (not shown), and the motor 3
8 is stopped, and the tray carrier 6 is stopped at its fully retracted position. In addition, as shown in FIG. 3B, the motor 38
The tray carrier 6 is locked at the above-mentioned stop potential by the self-locking function by the worm and worm wheel of the one-wheel gear 39 interposed in the deceleration drive mechanism of the pinion 40.

Next, after the above loading operation of the disc 1 is completed, when the playback/Bose switch 8 etc. shown in FIG. 1 is turned on, the motor 52 is activated and the turntable 5
1 rotates the disk 1, and the 3rd B
As shown in the figure, the optical pickup device 69
The laser beam is controlled to move in the radial direction (in the direction of arrow g), and the laser beam is irradiated and focused from the objective lens 70 onto the recording track on the lower surface of the disk 1, thereby performing desired reading and reproduction of the disk 1.

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

When the loading/eject switch 7 shown in FIG. 1 is turned on after the desired playback of the disc 1, the motor 38 is driven to rotate in reverse as shown in FIG. 6B, and the motor 38 drives the pinion through the worm gear 69. 40 is rotationally driven in the direction of arrow 1. Then, by the reverse operation during loading, the tray carrier 6 is pulled out horizontally in the direction of the arrow.

That is, the ejecting operation is a reverse operation of the loading operation, and first, the tray carrier 6 is pulled out horizontally in the direction indicated by the arrow by a predetermined length 15 from the position shown in FIG. 6D to the position shown in FIG. 6C. During this time, the bin 47 of the tray carrier 6 is removed from the lower end 61b of the control plate 61 in the direction of the arrow, as shown by the solid line in FIG. Then, the control plate 61 is rotated in the direction of arrow e by the spring 66, and the lifting arm 55 is pushed upward via both projections 62 and 63.
This 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 the arrow 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 and lifted above the turntable 51.

Next, the tray carrier 6 is pulled out horizontally in the direction of the arrow from the position shown in Figure 6C to the pull-out position shown in Figure 6A, and the disk 1 is moved by the disk tray 5 into the front opening 41. From there, it is horizontally pulled out to a drawer 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 the arrow □ to the position shown in FIG. 6B, the first
As shown in Figure 0B, the lower part of the pinion 26 is engaged with the rear end □ position of the fixed horizontal rack 46. While the tray carrier 6 is horizontally pulled out for a predetermined distance of 14 minutes in the direction of the arrow from the position shown in FIG. 6B to the pull-out position shown in FIG.
As shown in Figure B, it rolls on the horizontal rack 46 and moves along the arrow U.
It moves in the direction of the arrow while being rotated in the direction indicated by the arrow.

And at this time, in reverse when loading, pinion 2
The rotational force of 6 drives the inclined rack 19 in the direction of arrow 1, and as shown in FIG. It is then translated (downward) diagonally downward (in the direction of the arrow 1). Note that at this time, the spring 43 shown in the seventh shoe is stretched again.

From the above, the eject operation of disk 1 is completed.
The tray carrier 6 is mounted on a horizontal guide shaft (5) as shown in FIG.
) is brought into contact with the rear surface of the horizontal guide bearing 64 by the rear end support portion 75 and stopped, and the tray carrier 6
A sensor (not shown) detects the completion position of the drawer, and the motor 38 is stopped.

In summary, in this disc player 2, as shown in FIG. 5A, when the disc 1 is ejected by horizontally pulling it out from the front opening 4 through the disc tray 51 to the pull-out position outside the player main body 3 in the direction indicated by the arrow, 6
As shown in Fig. A, immediately before the tray carrier 6 is pulled out horizontally from the direction indicated by the arrow to the completion position and stopped, the disk tray 5 is moved toward the tray carrier 6 in the direction indicated by the arrow (in the direction indicated by the arrow). It is configured to move (down) diagonally downward (in the direction of the arrow 1) in parallel.

Therefore, in the ejected state of disk 1, the 5th A
As shown in the figure, the bottom surface 15m of the recess 15, which is the amount of discs to be placed on the disc tray 5, is lowered to a sufficiently low position relative to the upper edge 4& of the front opening 4 of the player body 3, and the bottom surface 15m The vertical dimension h4 of the gap 76 between the upper edge 4a and the upper edge 4a is sufficiently enlarged downward. As a result, after ejecting this disk 1, as shown in FIG.
As shown by the dashed line, the maximum rotation angle of the disk 1 when resetting the disk 1 on the disk tray 5 by rotating it in the direction of arrow V and then pulling it out diagonally upward in the direction of arrow W. #2 can be taken very large. From this, when setting the disc 1 horizontally on the disc tray 5 prior to loading, and when removing the disc 1 from the disc tray 5 after ejecting, the disc 1 is placed opposite the disc tray and 5. It is extremely easy to attach and detach.

Further, as shown in FIG. 6A, by configuring the disc tray 5 to be moved in parallel in the direction of arrow 1, which is the diagonal downward direction, while advancing in the direction of arrow 1, which is the direction in which it is pulled out, the disc tray 5 is moved in parallel in the direction of arrow 1, which is the diagonal downward direction. The disc tray 5 can be pulled out as much as possible outside the player main body 3 while keeping the amount IJ2 of the tray carrier 6 pulled out relatively small. As a result, the total length dimension 16 of the disc tray 5 and tray carrier 6 can be made extremely small, and the depth dimension of the player body 3 can be made extremely small. , to around 13 cIt, which is very close to the diameter of the disk 1 (12 cIn).

Next, a second embodiment of the loading/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 1,000-row four-link mechanisms so that it can be raised and lowered in the diagonal up and down directions (directions of arrows l and n). That is, each pair of left and right parallel links 78a, 78b
The lower ends of the left and right side plates 24a, 24 of the tray carrier B
b are rotatably supported via fulcrum pins 79a and 79b, respectively, and these respective pairs of parallel links 78m and 78b
The upper end is the left and right side plates 17m of the disc tray 5,
17b via fulcrum pins 80a and 80b, respectively, so as to be rotatable. and one parallel link 78a
and spring locking portions 82 provided on the left and right side plates 24m and 24b of the tray carrier 6.
Each pair of parallel links 78m and 78b is biased to rotate in the direction of arrow X in FIG. 11A by the force of a spring 86 passed between the rack and the frame. An arm 84 extending downward from the fulcrum pin 79m is integrally provided on one of the parallel links 78a, and as shown in FIG. 84 is brought into contact and rotation in the direction of arrow X is restricted.

Therefore, in this case, when the tray carrier 6 is pulled out horizontally from the front opening 4 to the outside of the player main body 6 in the direction indicated by the arrow, as shown in FIG. 83 forces each pair of parallel links 78a.

78b is being rotated in the direction of arrow be drawn out.

Immediately before the tray carrier 6 reaches the drawer completion position shown in FIG.
6, each pair of parallel links 78a, 781) is rotated in the direction of the arrow y, as shown in FIG. 11B, against the force of the spring 83.

As a result, as shown in the vs11B diagram, the tray carrier 6
Immediately before the disk tray 5 reaches the draw-out completion position, the disk tray 5 is moved diagonally downward (parallel to the arrow 1 direction) relative to the tray carrier 6 in the pull-out direction (arrow direction). Due to the parallel movement (downward movement) in the direction of the arrow 1, the vertical dimension h4 of the gap 76 mentioned above 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.

[Example of application]

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 a disc is ejected, when the disc tray is pulled horizontally out of the player main body from the front opening by the tray carrier, the disc tray is translated downward and the disc is placed on the disc tray. The gap between the placing surface and the upper edge of the front opening of the player body can be greatly expanded downward.

Therefore, as the display player has become much thinner and smaller, the amount that the disc tray can be pulled out of the player body is limited, and it is difficult to pull out the disc so that its entire diameter is exposed from the front opening to the outside of the player body. It is no longer possible to do so, and the vertical dimensions of the front opening are restricted.
Even if the gap between the disc on the disc tray and the upper part of the front opening of the player body becomes very small, the operation of attaching and removing the disc to and from the disc tray can be greatly expanded downward as described above. This can be done extremely easily by using the gap. This makes it possible to further reduce the thickness and size of the disc player.

Moreover, according to the present invention, when the disc tray is horizontally pulled out from the front opening to the outside of the player body by the tray carrier, the disc tray is configured to move diagonally downward parallel to the tray carrier in the drawing direction. Therefore, the disc tray can be pulled out to the maximum extent possible while keeping the amount of the tray carrier pulled out 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 very small.
