And a disc player in which a slide table on which a disc is placed is configured to be movable between a discharge position where the slide table is pulled out of the player main body and a storage position where the slide table is pulled inside the player main body. .

B Outline of the Invention The present invention provides a disc player in which a slide table on which a disc is placed is configured to be movable between a discharge position where the slide table is pulled out of the player body and a storage position where the slide table is pulled in the player body. Since the driving force for moving the slide table from the storage position to the discharge position is obtained by the driving means in which the driving force is gradually accumulated as the slide table is moved from the discharge position to the storage position, the slide table is slid without using the electric motor. The table can be moved from the storage position to the discharge position.

C Prior Art As a disc player of this type, the present applicant has previously filed, for example, Japanese Patent Application No. 59-5383 (Japanese Patent Laid-Open No. 60-150262).

In the invention of this prior application, a rack is provided along the moving direction of the slide table on which the disk is placed, and the rack is driven by a pinion rotatably driven by an electric motor, so that the slide table is placed outside the player body. It is configured to move (load) the ejected position pulled out to the housed position retracted into the player body, and to move (unload) the slide table from the housed position to the ejected position by the reverse rotation drive of the electric motor. .

D Problem to be Solved by the Invention However, in order to move the slide table between the discharge position and the storage position, a considerably large torque is required. Therefore, the slide table is electrically driven like the above-mentioned prior invention. When moving by a motor, an electric motor capable of obtaining a large torque must be used, resulting in extremely high cost.

Further, as is well known, the diameter of the compact disc used in the compact disc player is as small as 12 cm, so that a portable compact disc player has been developed by taking advantage of this advantage. In this case, the battery is driven, but the electric motor that can obtain a large torque as described above consumes a large amount of battery. For this reason, a large battery having a large capacity must be used, which is inconvenient for a portable type that requires a reduction in size and weight.

Therefore, the present invention enables the slide table to be moved from the storage position to the discharge position without using an electric motor.

E Means for Solving Problems According to the present invention, in the above-described disc player, the driving force for moving the slide table from the storage position to the discharge position is gradually accumulated as the slide table is moved from the discharge position to the storage position. The driving means (for example, a tension coil spring or a mainspring) is provided.

F Action According to the present invention, when the slide table is moved from the discharge position to the storage position, a driving force (spring force) for moving the slide table from the storage position to the discharge position is gradually accumulated in the driving means such as a tension coil spring or a mainspring. To be done. The accumulated driving force moves the slide table from the storage position to the ejection position. Therefore, the slide table can be moved from the storage position to the discharge position without using the electric motor.

G ₂ Next, the details of the storing and discharging operation of the slide table and the operation of the driving means will be described with reference to FIGS. 1 to 5B.

First, as shown in FIG. 3A and FIG. 4A, before the start of the storing operation, the slide table 5 is pulled out from the front opening 3 to the outside of the player main body 1 in the direction of arrow a ′ with a predetermined pullout amount L. And the disc player 8 on the slide table 5
By the biasing force of the spring 33 and the guiding action of each of the tilt guides 13, the slide table 5 is slanted upward (in the direction of arrow g) in parallel with respect to the slide table 5 in the retracting direction. The front end surface of the horizontal guide bearing 21 of the slide table 5 is the front wall 25a of one vertical chassis 25.
And the discharge position of the slide table 5 is regulated. By the way, at this time, the tension coil spring 40 is returned to a substantially free length.

Next, the disc 4 is placed in the recess 10 of the disc player 8 and set in a positioned state. By manually pressing the lid 16 at the front end of the slide table 5, the slide table 5 is horizontally moved in the arrow a direction while being guided by the horizontal guide shaft 23 and the horizontal guide rail 24. At this time, as the slide table 5 is pushed from the discharge position, the tension coil spring 40 is gradually stretched, and the tension coil spring 40 is gradually provided with a driving force (spring force) for moving the slide table 5 to the discharge position. Accumulated.

Next, the slide table 5 is continuously pushed horizontally in the direction of arrow a, whereby the disc 4 is pushed horizontally between the turntable 53 and the clamper 55. When the slide table 5 is pushed to a position where the centers of the disc 4 and the turntable 53 coincide with each other, the rear end portion 8a of the disc table 8 causes the rear wall 25b of one vertical chassis 25 to move.
And the disk table 8 is stopped at that position.

Then, even after the disc table 8 is stopped, the slide table 5 is pushed horizontally in the direction of arrow a. Then, at this time,
As shown in FIG. 4B, the disc table 8 is translated (lowered) vertically in the direction of the arrow h by the guiding action of each tilt guide 13. By this parallel movement, the disc 4 on the disc table 8 is lowered and horizontally mounted on the turntable 53. The disc 4 is mounted on the turntable 53 immediately before the disc table 8 reaches the lowest position, and when the disc table 8 reaches the lowest position, the disc 4 is levitated from the recess 10 of the disc table 8. The disk 4 is free to rotate.

By the above, the slide table 5 is completely pushed to the storage position in the player main body 1, and the slide table 5 is pushed.
The front opening 3 of the player main body 1 is closed by the lid 16 at the front end of the player.

At this time, as shown in FIG. 5A, the slide table 5
The locked portion 47 is engaged with the lock portion 46 of the lock lever 43, and the slide table 5 is locked at the storage position.
Immediately before this locking, the projection 72 of the control plate 66 is pressed by the rear end surface of the horizontal guide bearing 21 of the slide table 5, and the control plate 66 slides against the spring 67 in the arrow e'direction. Then, the pin 70 of the control lever 61 falls into the lower recess 69 of the control plate 66, whereby the control lever 61 is rotated in the direction of arrow i, and the pin 63 of the control lever 61 causes the protrusion 65 of the lifting arm 56 to move. Is lifted and the lifting arm 56 is rotated in the direction of arrow d by the spring 59. Then, the clamper 55 presses the disk 4 from above by the spring force of the spring 59 to fix the disk 4 on the turntable 53.

Next, after the above-described storing operation of the disk 4 is completed,
The disk 4 is rotationally driven by the disk drive motor 54, and the movement of the optical pickup device 77 in the radial direction of the disk 4 (direction of arrow f) is restricted, so that the disk 4
The desired read reproduction is performed.

Then, after the desired reproduction of the disc 4, the eject button 6 on the front panel 2 of the player body 1 is pressed to slide the eject plate 49 against the spring 51 in the direction of arrow c '. Then, as shown in FIG. 5B, the pressed portion 50 of the eject plate 49 presses the pressed portion 48 of the lock lever 43, and the lock lever 43 is rotated in the direction of the arrow b ′ against the spring 45. As a result, the engagement of the locked portion 47 of the slide table 5 by the lock portion 46 of the lock lever 43 is released, and the lock of the slide table 5 at the storage position is released.

Then, at this moment, the stretched tension coil spring 40 contracts, and the driving force (spring force) accumulated in the tension coil spring 40 moves the slide table 5 from the storage position in the arrow a'direction. It Then, at the first stage of the movement of the slide table 5 in the direction of the arrow a ′,
Due to the spring force of the spring 33, the disc player 8 causes the arrow h '.
The disk 4 is moved in parallel (moved up) in the direction, and then the disk 4 is housed again in the recess 10 of the disk table 8 and the turntable
Levitated above 53. As shown in FIG. 5B, when the eject plate 49 slides in the direction of the arrow c ', the protrusion 74 of the control lever 61 is pressed by the pressing portion 75 of the eject plate 49, and the control lever 61 moves the arrow i. It is rotated in the'direction. Thereby, the pin 63 of the control lever 61 presses the protrusion 65 of the elevating arm 56, the elevating arm 56 is rotated in the direction of the arrow d ′ against the spring 59, and the clamper 55 is elevated. Then, when the control lever 61 is rotated in the direction of the arrow i ′, the pin 70 is separated upward from the lower recess 69 of the control plate 66. Since the control plate 66 is slid in the direction of arrow e by the spring 67 by the movement of the slide table 5,
The pin 70 of the control lever 61 is engaged with the recess 68 on the upper stage of the control plate 66 and is held in this state.

Next, the slide table 5 is continuously pulled by the tension coil spring 40.
Is horizontally moved in the direction of the arrow a'to the ejection position by the driving force (spring force), and the disc 4 on the disc table 8 is pulled out of the player main body 1 through the front opening 3. Then, the front end surface of the horizontal guide bearing 21 of the slide table 5 is brought into contact with the front wall 25a of the one vertical chassis 25, the movement of the slide table 5 is stopped, and the discharging operation is completed.

As described above, as the slide table 5 is moved from the discharge position to the storage position, the tension coil spring 40 is gradually extended, and the tension coil spring 40 has a driving force for moving the slide table 5 from the storage position to the discharge position. Since the (spring force) is gradually accumulated, when the lock of the slide table 5 at the storage position is released, the slide table 5 is moved from the storage position to the discharge position by the accumulated driving force.

By the way, the driving means using the tension coil spring 40 has an extremely simple structure and can be arranged in an extremely small space in the player main body 1, and since it is not necessary to use a gear or the like, there is no fear of gear noise or the like. Absent. Further, as in the embodiment, by using the extension coil spring 40 guided by the guide pulley 38 and having a long free length, it is possible to use one having a small spring constant even if the slide table 5 has a long moving distance. The slide table 5 can be moved extremely smoothly.

G ₃ Next, another driving means and its operation will be described in detail with reference to FIGS. 6 and 7.

In this case, the drive means is constituted by a mainspring (spiral spring) 81. First, a pair of guide gears 82 and 83 are rotatably supported on the outer surface of one vertical chassis 25 in the player main body 1 near the front and rear ends. A drive gear 84 is integrally formed with the guide gear 83 on the rear end side, and the drive gear 84 is also engaged with an intermediate gear 85 rotatably supported on the outer surface of the vertical chassis 25. The drive gear 88 formed on the motor shaft 87 of the mainspring motor 86 is engaged with the intermediate gear 85. The mainspring motor 86 is a case 89 in which a band-shaped mainspring 81 is wound and housed, and both ends of the mainspring 81 are locked by a locking portion 90 of the case 89 and a slit 91 of the motor shaft 87. There is. A guide pulley 92 is formed integrally with the intermediate gear 85, and a guide pulley 92 is formed near the front end guide gear 82.
93 is rotatably supported. A timing belt 94 is wound between the pair of guide gears 82 and 83 along the front-rear direction. The pair of guide pulleys 92, 93 are arranged so as to push the lower part of the timing belt 94 upward, and thereby the winding angle of the timing belt 94 around the pair of guide gears 82, 83 is made large. A part of the timing belt 94 is fixed to the lower surface of the horizontal guide bearing 21 of the slide table 5 with screws 95 or the like.

According to the above-described example, when the slide table 5 is pushed in the direction of the arrow a from the discharge position to the storage position, as shown by the solid line to the alternate long and short dash line in FIG. The drive gear 88 is rotationally driven in the direction of arrow j via the gear 84 and the intermediate gear 85, and the mainspring 81 of the mainspring motor 86 is gradually wound around.
The driving force (spring force) is gradually accumulated in 81.

Then, when the lock of the slide table 5 at the stored position is released in the same manner as described above, the drive gear 88 is rotationally driven in the direction of the arrow j'by loosening the mainspring 81. Then, the guide gear 83 is rotationally driven via the intermediate gear 85 and the drive gear 84, and the timing belt 94 is driven. As a result,
The slide table 5 moves from the storage position to the discharge position by an arrow a '
Is moved in the direction. It should be noted that, as in this example, the one in which the linear motion of the slide table 5 is exchanged for the rotary motion of the mainspring 81 by the timing belt 94 is much smoother than the one in which the linear motion is exchanged for the rotary motion by the rack and the pinion. It can operate.

G ₄ Next, the friction mechanism and its operation will be described in detail with reference to FIGS. 2 to 3B and FIGS. 8 to 10B.

First, as shown in FIGS. 2 to 3B, the moving direction of the slide table 5 (arrow a,
A first resistor 97 is provided along the (a 'direction). The first resistor 97 is a strip-shaped tape having abrasion resistance, and for example, Myra (trademark of DuPont) formed of polyethylene terephthalate is used. In the embodiment, as shown in FIG. 8, three first resistors 97 are stacked, and both ends of the first resistor 97 are fixed to the front and rear ends of the other vertical chassis 26 as shown in FIG. On the holding plate
Attached by screws 100 through 99.

Next, as shown in FIG. 8, three second resistors 101 are laminated so as to sandwich the three first resistors 97, respectively. The second resistor 101 is a tongue-shaped film having abrasion resistance, and for example, a film in which polyamide is filled with graphite is used.

The second resistor 101 is formed in a rectangular shape having a punched hole 102 in the central portion as shown in FIG. 10A, and this is bent with the first resistor 97 sandwiched as shown in FIG. 10B. Has been. The second resistor 101 is bent very surely by the punching hole 102 and surely contacts the first resistor 97. And the three second resistors 101 are respectively the three first resistors.
The resistor 97 is sandwiched and attached to the mounting plate 103 by the screw 105 via the pressing plate 104.

The mounting plate 103 is the side plate 18b of the slide table 5.
It is attached by a screw 106 to the rear end. A leaf spring 107, which is an urging member, is attached to the attachment plate 103, and the tip 107a of the leaf spring 107 presses the first and second resistors 97 and 101 toward the attachment plate 103 side. The first and second resistors 97 and 101 are in contact with each other at a predetermined contact pressure.

According to the friction mechanism configured as described above, when the slide table 5 is driven from the storage position to the discharge position by the driving means such as the tension coil spring 40 and the mainspring 81, the first
The second resistor 105 is moved over the distance L while the second resistors 97 and 101 are in contact with each other. As a result, a frictional force proportional to the pressure force applied by the leaf spring 107 is generated between the first resistor 97 and the second resistor 101, and a very good resistance feeling is given to the slide table 5 when the slide table 5 is ejected. You can

By the way, according to the above-mentioned first and second resistors 97 and 101, the frictional force can be adjusted very easily by changing the number of laminated sheets, the combination of materials, the pressure force applied by the leaf spring 107, etc. The frictional force corresponding to the driving force of the driving means can be easily set.

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

In addition to the compact disc player, the present invention
It can be applied to various disc players using various audio discs and video discs.

H Effect of the Invention According to the present invention, the driving force for moving the slide table from the storage position to the discharge position is obtained by the drive means in which the driving force is gradually accumulated as the slide table is moved from the discharge position to the storage position. The slide table can be moved from the storage position to the discharge position (auto eject) without using a motor. Therefore, an expensive electric motor that generates a large torque for moving the slide table is unnecessary, and the cost can be extremely reduced. Also, since an electric motor for moving the slide table is not required, even if it is driven by a battery, it suffices that the disc rotation drive motor has a required battery capacity, and it is not necessary to use a large battery having a large capacity. The size and weight can be greatly promoted, which is very convenient for a portable disc player.
