[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a CD player or other disk reproducing apparatus having an autochanger function, and more particularly to an eject mechanism for a magazine in a disk reproducing apparatus provided with a magazine in which disk-shaped recording media for reproduction are stored in parallel. About.

[0002]

2. Description of the Related Art In recent years, digital recording type disc-shaped recording media (hereinafter, abbreviated as "discs") such as CDs (compact discs) and reproduction apparatuses thereof have been widely used.
In particular, a reproducing apparatus having an autochanger function of a disk is convenient because it has less trouble of changing a disk, and has been widely used in general.

There are various types of disc reproducing apparatuses of this kind, and a generally well-known disc reproducing apparatus is provided with a magazine in which a plurality of discs are stored in parallel, and selected from the magazines. There is a system in which one disk is taken out and played. In such a disc reproducing apparatus, a magazine storage section is provided adjacent to a drive unit for driving a disc, and a disc can be exchanged between a magazine stored in the storage section and a drive unit having an optical pickup or the like. It has become. In particular, the storage unit is equipped with a magazine eject mechanism, and when exchanging the disc stored in the magazine, the magazine is ejected outside the machine by operating the eject mechanism by operating the switch on the operation panel. Can be.

As shown in FIG. 14, the conventional eject mechanism is based on a slider S slidably provided in a magazine M loading direction, and a portion of the slider S is provided with a slow oil damper. D.
FIG. 14A shows a state in which the magazine is stored in the storage unit. At this time, the slider S is locked while being urged toward a loading port (not shown) by the elastic member F, and is operated by a switch operation on the operation panel. When the lock is released, the slider S advances in the direction of the loading port while pressing the magazine M as shown in FIG. The oil damper D has a pinion that meshes with a rack formed on the side edge of the slider S, and has a structure in which rotating blades (not shown) provided at one end of a rotating shaft are sealed in an oil tank. According to such an ejection mechanism, the advancing speed of the slider S due to the rapid restoration of the elastic member F can be reduced by the oil damper D, and the magazine can be prevented from jumping out of the loading port.

[0005]

However, the use of an oil damper as in a conventional eject mechanism is costly, and the oil damper changes the viscosity of the oil depending on the temperature. And the like. For example, when the temperature is low, the viscosity of the oil is high, causing an overload in the drive system. Conversely, when the temperature is high, the viscosity of the oil decreases, and the load resistance at the time of restoration applied to the elastic member decreases. There was a further disadvantage that the magazine would protrude from the loading port.

In particular, according to the conventional eject mechanism, the magazine can be stopped at a predetermined take-out position together with the slider by the action of the oil damper in a normal state, but at this time, the magazine is attached to the end face of the magazine opposite to the loading port. Since the slider is only in contact with the one used in an automobile, there is a drawback that the magazine at the take-out position drops from the loading port due to running vibration.

It is an object of the present invention to reliably stop a magazine at a predetermined take-out position regardless of the use environment and to maintain the stopped magazine until the magazine is removed from a loading port.

[0008]

According to the present invention, there is provided a magazine storage unit in which a plurality of disk-shaped recording media are accommodated in parallel adjacent to a drive unit for driving the disk-shaped recording media. And a dispenser for transferring the magazine stored in the storage toward the loading slot, and a dispensing position with the dispensing means. And a holding means for holding the magazine transferred to the magazine so that the magazine can be removed from the loading port, wherein the holding means has one end urged inwardly of the storage section and slidably contacts the outer peripheral surface of the magazine. A disk having an outer peripheral surface of a magazine to which one end of the locking member is slidably contacted, the locked portion being locked at one end of the locking member at a take-out position. There is provided a magazine eject mechanism in living devices.

In particular, in the magazine ejecting mechanism according to the second aspect of the present invention, a magazine storage section in which a plurality of disk-shaped recording media are stored in parallel is provided adjacent to a drive unit for driving the disk-shaped recording medium. In a disc reproducing apparatus in which a loading port for inserting and removing the magazine is formed in the storage section, a pair of sliders that can slide in a predetermined section along the loading direction of the magazine are provided in the storage section in series. And, the pair of sliders are connected by an elastic member, and one of the sliders moves toward the loading port by the restoring force of the elastic member, and is used for discharging a magazine for transferring a magazine to a removal position. And one end of the other slider is urged inwardly of the storage section so that a hook-shaped locking member that slides on the outer peripheral surface of the magazine is swingable. The stopper is formed at a position on the outer peripheral surface of the magazine where one end of the locking tool is slid in contact with the one end of the locking tool at the removal position. An unlocking portion is provided in the storage section for retracting one end of the locking tool from the locked portion of the magazine in the traveling direction of the slider provided with the locking tool.

In this embodiment, the pair of sliders 1
As shown in FIG.
Connected by three. The elastic member 23 is a tension spring, and both ends of the elastic member 23 are leg portions 1 of the sliders 11 and 12, respectively.
Locked to 5,17. When the magazine 5 is stored in the storage section 4 as indicated by an imaginary line, one of the sliders 11 is locked while being urged in the direction of the loading port 6 by the elastic member 23. Reference numeral 24 denotes a lock lever for locking the slider 11. The lock lever 24 has one end attached to the back side of the seat plate 10 in the vicinity of the slider 11, and can swing about the attachment portion 25 as a fulcrum. . A torsion spring 26 is attached to the mounting portion 25 to urge the lock lever 24 clockwise in the drawing, and a lock pin 27 for restricting swing is provided at the other end of the lock lever 24. Place the lock pin on the seat plate 10
, And project above a notch 28 formed in connection with the guide hole 14.

The lock lever 24 has a slider 11
When the magazine 5 is stored in the storage portion 4, the leg portion 15 of the slider 11 separates from the guide groove and is formed on the side edge of the lock lever 24 when the magazine 5 is stored in the storage portion 4. It is designed to lock. Then, when an eject switch on an operation panel (not shown) is operated to take out the magazine 5 of the storage unit 4, the slide cam 29 disposed on the back side of the storage unit 4 advances toward the lock lever 24 and presses one end thereof. It has become. As a result, the lock lever 24 swings counterclockwise in the drawing against the elasticity of the torsion spring 26, and the leg 15 of the slider 11 coincides with one end of the guide groove formed in the lock lever 24. . Thus, the slider 11 advances along the longitudinal direction of the guide hole 14 while engaging the leg 15 with the guide groove, and the magazine 5 is directed toward the loading port 6 by the hook 13 formed on the rear side. It will extrude. 3 and 5, reference numeral 30 denotes a guide pin projecting from the seat plate, and the guide pins 30 are arranged in series along the loading direction f of the magazine 5.

As shown in FIG. 6, the bottom of the magazine 5 has three grooves 31, 32, 33 from one end to the other end.
The groove 31 at the left end of the figure is formed at a position corresponding to the guide pin 30. That is, when the magazine 5 is loaded into the storage unit 4 or when the storage unit 4
When the magazine 5 is taken out, the guide pin 30 and the groove 31 are engaged with each other, so that the magazine 5 can be smoothly slid along the guide pin 30.

The L-shaped groove 32 at the right end corresponds to the lock lever 24. When the magazine 5 is stored in the storage section 4, the lock pin 27 of the lock lever is inserted into the deepest portion of the groove 32. Then, the magazine 5 is locked.

Further, the central groove portion 33 corresponds to the locking member 19, so that the magazine 4 can be loaded into the storage portion 4,
When taking out the magazine 5 from the storage section 4, the groove 33
The one end 19b of the locking member 19 is in sliding contact with the locking member 19. In particular, the groove 33 is formed with a locked portion 34 to which the one end 19b of the locking tool is locked when the magazine 5 is transferred by the slider 11.

In FIG. 6, reference numeral 35 denotes a projection formed on the bottom of the magazine. According to the projection 35, when loading the magazine 5 into the storage section 4, the sliders 11 and 12 interfere with the bottom of the magazine 5. Can be prevented.

As is apparent from FIG. 7, the projection 35 has a required height and is brought into contact with the seat plate 10 to form a constant gap between the bottom surface of the magazine 5 and the seat plate 10. For this reason, the magazine 5 can be slid on the seat plate 10 without the sliders 11 and 12 interfering with the bottom surface thereof. FIG. 7 shows a state in which the magazine 5 has been transferred to the unloading position by the slider 11. At this time, the slider 11 reaches one end of the guide hole 14 and is urged toward the loading port 6 by the elastic member 23. Has stopped. The other slider 12 is urged by the elastic member 23 to the opposite side of the loading port 6, and one end 19 b of the locking member 19 provided on the slider 12 is engaged with the locked portion 34 of the magazine 5. It restricts the magazine 5 from moving in the direction of the loading port 6 by stopping.
When the portion of the magazine 5 protruding from the loading port 6 is pulled in this state, the slider 12 also advances in the direction of the loading port 6 against the elasticity of the elastic member 23. Since the lock release portion 21 facing the one end 19b of the locking tool is formed on the seat plate 10 (on the track of the locking tool), the one end 19b of the locking tool is imagined as the slider 12 advances. Lock release part 21 as shown by the line
, And sinks into the back side of the seat plate 10, whereby the engagement between the one end 19b of the locking tool and the locked portion 34 of the magazine is released. Then, the slider 12 is pulled back to the far side (reverse side) of the loading port 6 by the elastic force of the elastic member 23. As a result, the magazine 5 is no longer held by the locking member 19 and can be removed from the loading port 6.

Here, the operation of the eject mechanism configured as described above will be described. First, the magazine 5 is stored in the storage unit 4.
Is not stored, a pair of sliders 11 and 12
Are attracted to each other by the elastic member 23 and are stationary at one end of the guide holes 14 and 16, respectively. Here, as shown in FIG. 8, when the magazine 5 is pushed from the loading port, one end surface thereof hits the hook portion 13 of the slider, whereby the slider 11 also resists the elasticity of the elastic member 23 and is loaded together with the magazine 5. Is moved to the far side.

When the slider 11 reaches a predetermined position, the lock lever 24 shown in FIG. 5 swings clockwise, and the slider 11 is locked while being urged by the elastic member 23 toward the loading port. At the same time, the lock pin 27 of the lock lever 24 is introduced into the groove 32 of the magazine 5 and the magazine 5 is also locked. FIG. 9 shows the state at this time. FIGS. 9A and 9B show a state where the magazine 5 is stored in the storage unit 4. In this state, a CD can be exchanged between the magazine 5 and the drive unit 3 to reproduce the CD.

On the other hand, when the CD stored in the magazine 5 is exchanged, the user can operate the eject switch (not shown) on the operation panel to pay out the magazine 5 to the take-out position as shown in FIG. it can. That is, when the eject switch is operated, the slide cam 29 shown in FIG. 5 advances to swing the lock lever 24. Then, as is clear from the above description, the lock of the slider 11 and the magazine 5 by the lock lever 24 is released, and the slider 11 pushes the magazine 5 by the hook 13 with the restoring force of the elastic member 23 in the direction of the loading port 6. To progress to. Thereafter, the slider 11 is moved to the guide hole 1.
4 stops, and the one end 19b of the locking tool that has slidably contacted the groove 33 of the magazine 5 is locked to the locked portion 34. For this reason, the magazine 5 is stopped at a predetermined position (removal position) without popping out of the loading port 6 due to inertia, and maintains its state without rattling or falling down from the loading port 6 even if some vibration is applied. become. In this state, as described above, the magazine 5 can be removed from the loading port 6 by pinching a part (about 1/4 of the whole) of the magazine protruding from the loading port and pulling it with a required force. .

FIG. 11 shows a state in which the magazine at the take-out position is pulled out. When the magazine 5 is pulled forward as shown in FIG. The slider 12 also advances in the direction of the loading port 6 via the stopper 19, and as a result, as described above, the stopper 1
The lock of the magazine 5 by 9 is released, and the magazine 5 can be removed from the loading port 6.

A preferred example of the present invention has been described above.
The eject mechanism according to the present invention can be provided not only at the bottom of the storage unit 4 but also at the top or the like. In addition, although a CD player is taken as an example of a disc reproducing apparatus, it is needless to say that the present invention can be applied to a DVD player and the like.

Further, according to the above example, the slider 11 is used as the magazine dispensing means, and the slider 12 provided with the locking member 19 is used as the holding means. Instead of connecting, Figure 1
2, the slider 11 may be urged toward the loading port 6 by the elastic member 23 as in the related art, and the slider 12 may be urged toward the opposite side of the loading port 6 by another elastic member 23 '. .
Further, the configuration may be such that only the locking tool 19 is used without using the slider 12 as the magazine holding means. For example, as shown in FIG. 13, a locking member 19 is swingably attached to the back surface of the seat plate 10, and one end 19 b side of the locking member 19 is slidably contacted with the outer peripheral surface of the magazine 5 by a leaf spring or a torsion spring. May be applied. However, in this example, the contact surface between the locking tool 19 and the locked portion 34 of the magazine 5 is formed as a slope as shown in FIG. It is necessary to be able to evacuate from 34.

[0028]

As is clear from the above description, the eject mechanism of the present invention does not use an oil damper as in the prior art,
The magazine is stopped at the take-out position by the locking device, so that the cost can be reduced, and the magazine can be stopped and held at the take-out position regardless of the operating environment. Will not fall from the loading port.

Further, the locking device is attached to a slidable slider along a fixed section along the loading direction of the magazine, and the lock by the locking device can be released while the magazine is being pulled out, so that operability is good. In addition, since the slider and the magazine dispensing slider are connected by an elastic member, the impact force when stopping the magazine being transferred by the locking device can be reduced, so that the magazine is not locked by the locking device. There is no fear of popping out of the loading port, and no impact sound is generated. Furthermore, the number of parts can be reduced because the elastic member is also used for paying out and holding the magazine.
