Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an improvement in a disc loading mechanism of a disc player device.

(Conventional technology and its problems) Conventionally, various types of disk loading mechanisms of a disk player device have been proposed. However, a disk tray is provided so as to be movable back and forth with respect to the disk player body. What is loaded in a horizontal state is widely used.

Such a loading mechanism includes a disk tray, a chuck arm for mounting a disk brought to the disk mounting portion by the disk tray to a drive system, and the like, which are automatically loaded by a motor. In some cases, the disk tray is stored manually without using a motor or the like. The former requires a complicated mechanism and an electrical control circuit, and is usually used for high-priced devices even if the configuration is complicated and cost-effective. A loading mechanism is used.

This type of disc loading mechanism is urged by springs in the direction in which the disc tray normally ejects the disc and the direction in which the chuck arm presses against the disc on the disc tray. , Manually push in against the spring, and move the chuck arm onto the disc tray at the timing when the disc tray is stored in the main body,
When ejecting the disc tray, a configuration in which the lock of the disc tray is unlocked by an eject operation, the chuck arm is pulled away from the disc, and the disc tray is ejected by the force of a spring will be common.

However, since the operation of the disc tray and the operation of the chuck arm are each performed mechanically with timing as described above, a malfunction may occur.

That is, when the disc is loaded, the chuck arm lock lever, which locks the chuck arm at a position separated from the tray by pressing the tray, is unlocked, but the lock to the tray storage position and the lock of the chuck arm lock lever are locked. Even if the release timing is set at the same time, the chuck arm lock lever is unlocked before the tray is completely locked in the storage position due to manufacturing or assembly errors, and the chuck arm moves onto the disk. There is a danger that the operation timing may drop, causing the tray to be pushed down to the storage position.However, if the tray is released, the tray will be ejected with the chuck arm lowered and the disc will be ejected. And the risk of damaging the disk drive system.

Conversely, there may be cases where the lock of the chuck arm is not released even though the tray is locked at the disc loading position, and a mechanism that ensures the operation timing of locking the tray and unlocking the chuck arm is desired. Was rare.

(Purpose of the invention) The purpose of the invention is to solve the above-mentioned problems.
It is an object of the present invention to provide a novel disk player device which can always reliably lock a tray to a disk mounting position stored in a player main body and unlock operation of a chuck arm.

(Summary of the Invention) A tray provided so as to be movable between a disk mounting / dismounting position where a disk can be freely mounted outside the player main body and a disk mounting position where the disk can be mounted on a disk mounting portion in the player main body, and a disk A chucking position for chucking, a chucking member movably arranged between a non-chucking position where the chucking of the disc is released, and a lock lever connecting the tray and the chucking member, The lock lever has a first holding portion for holding the chucking member at the non-chucking position, and a second holding portion for holding the tray at the disc mounting position with the contact portion with which the tray abuts. A first engaging portion that engages with a first holding portion of the lock lever is provided on the chucking member; The tray is provided with a second engaging portion that engages with the second holding portion of the lock lever and an abutting means that abuts on an abutting portion of the lock lever. When the tray is brought into contact, the abutting means of the tray abuts on the abutting portion of the lock lever, whereby the first holding portion of the lock lever and the first engaging portion of the chucking member are in contact with each other. After the engagement is released, the second engaging portion of the tray is engaged with the second holding portion of the lock lever, so that the chucking member is moved from the non-chucking position to the chucking position. A disc player device wherein the tray is held at a disc mounting position.

(Embodiment) FIG. 6 is a perspective view showing the appearance of the disc player device of the present invention. In the opening 1b formed in the front panel 1a of the disc player body 1, a disc is inserted from the front of the player into the player body. The tray 2, which is horizontally loaded on the disk mounting portion 10 provided on the side, is arranged to be movable back and forth by a well-known guide mechanism (not shown).

Are formed, and disk support pieces 3 to 3 are further arranged. These disk support pieces are arranged such that the tray 2 is moved to a disk mounting position in the player main body 1 and the disk is carried on the disk mounting portion to be stored in the tray (conventionally. The description of the configuration is omitted because it is a more commonly used means). During the transfer of the disk, the disk D is supported at a predetermined distance from the tray 2 and the disk D is brought on the disk mounting portion. By being pressed, the disc is stored in the tray and operates so as not to hinder the loading of the disc on the turntable 12.

In addition, the front panel 1a is provided with an eject lever 24 for moving the tray 2 to the outside of the main body to eject the disc, various operation buttons 5, a display unit 6, and the like.

1 to 5 are side views showing a tray driving mechanism in the player main body 1. FIG.

The tray 2 is arranged to be movable back and forth by a well-known guide mechanism (not shown), that is, to be movable left and right as viewed in the figure, and is always urged forward by the spring 11 toward the front of the main body 1.

The tray 2 is provided in the player body 1 and in the disc mounting portion 10.
A disc rotation motor 13 having a turntable 12 attached to a rotating shaft is disposed below, and a chucking member 14 which is pressed against the turntable 12 with a disc D therebetween is provided above the tray 2 facing the turntable 12. It is supported by a chuck arm 15 rotatably mounted on a chassis 19 by a support member 17 and a shaft 16.

The chuck arm 15 is turned on the turntable 12 by a spring 18.
The chucking member 14 is urged in a direction in which the chucking member 14 is pressed.

A lock lever 20 that locks the tray 2 at a storage position in the main body 1 and locks the chuck arm at an upper position separated from the tray 2 is provided on a chassis side plate (not shown) at a substantially intermediate portion in the player main body 1. It is rotatably mounted by a shaft 21.

The lock lever 20 has an engaging arm 20a that engages with the protrusion 2c on the side surface of the tray 2, and a hook portion 20b that can engage with the pin 15a on the side surface of the chuck arm. It is supposed to be.

When the tray 2 is stored in the main body 1, the lock lever 20 is pushed by a pin 2d on the side of the tray by pushing the tray 2 further from the lock position by a predetermined stroke, and is rotated clockwise, that is, in the unlocking direction. It has become so.

24 releases the locked state of tray 2 and
An ejecting lever that pushes the chuck arm to an upper position where it can be locked by the hook portion 20b of the lock lever 20, and an operating portion 24a that projects forward from an opening 1c formed in the front panel 1a at one end, Is formed with an engaging portion 24b which engages with the projection 2c of the tray to prevent the tray from being ejected, and further above the engaging portion 24c which engages with the pin 15a on the side of the chuck arm to push it up. Have been. The spring 26 constantly urges the clockwise rotation, and the protrusion 27 regulates the non-operating position.

The disc player apparatus of the present invention has the above-described configuration. Next, the operation of the disc player apparatus will be described step by step.

FIG. 1 shows a state in which the tray 2 is opened to a disk mounting / dismounting position in front of the player main body 1. In this state, the disc can be attached and detached from outside the player main body 1.

The disc supporting pins 3 to 3 protrude from the disc mounting portion 2a of the tray 2 so that the discs D can be mounted at predetermined intervals.

On the other hand, in the player main body 1, the chuck arm 15 locks the pin 15 a on the side surface thereof with the hook portion 20 b of the lock lever 20, so that the chucking member 14 turns the turntable 12.
Locked at a position away from the top.

When the chuck arm 15 is locked, the lock lever 20 is slightly rotated clockwise against the spring 22, and separates the engagement arm 20a out of the movement locus of the protrusion 2c on the side of the tray. The positional relationship between the hook portion 20b and the engagement arm 20a is determined so that the positions are set as described above.

In this state, the disk D can be mounted on the disk mounting portion 10 in the player main body by mounting the disk D on the disk mounting portion and pushing the tray 2 into the player main body.

FIG. 2 shows a state where the tray 2 on which the disk is placed is pressed and stored in the player main body 1. The X position in the figure indicates the position when the tray 2 is locked at the storage position, that is, the disk mounting position.

When the tray 2 is pressed and stored in the main body 1, when the chuck arm 15 is locked by the lock lever 20, the engagement arm 20 a of the lock lever 20 is moved to the protrusion 2 c on the side of the tray.
The projection 2c is separated from the movement locus of
Pass backwards without hitting 20a.

When the tray 2 passes through the storage position X and is further pushed into the Y position, the protrusion 2d on the side thereof presses the front edge of the lock lever 20 and rotates clockwise against the spring 22. From the pin 15a of the chuck arm 15 to the hook 2
0b is released and the lock is released.

As a result, the chuck arm 15 is pressed against the turntable 12 with the elasticity of the spring 18 sandwiching the disc D therebetween, and the disc D is mounted on the turntable 12.

When the pressing of the tray 2 is released from this state, the tray 2
Is returned to the front of the player body by the elasticity of the spring 11,
The lock lever 20 also returns counterclockwise due to the elasticity of the spring 22. At this time, since the lock lever 20 does not engage with the pin 15a of the chuck arm 15, the lock arm 20a is rotated until the engagement arm 20a reaches a position where it can engage with the protrusion 2c of the tray 2.
Is locked to its storage position, that is, the disk mounting device. This state is shown in FIG.

By the above operation, the disk D is transferred to the disk mounting section 10 of the player main body, and the mounting on the turntable 12 is completed. Then, the motor 13 is rotated by well-known control means (not shown), and information recorded on the disc can be reproduced by a pickup (not shown).

When the tray 2 is pressed to the storage position by the above-described operation, the unlocking of the chuck arm 15 is performed by an overstroke that pushes the tray 2 further rearward from the storage position, and the tray 2 is returned by the overstroke by returning the tray 2 by the overstroke. Since the lock to the storage position 2 is performed, there is no danger that the timing of the unlocking operation of the chuck arm and the locking operation of the tray to the disk mounting position may be out of order, thereby causing a malfunction, and the operation timing can always be reliably taken. .

Next, the operation of ejecting a disc from the disc mounted state shown in FIG. 3 to the player main body will be described.

When the operating portion 24a of the eject lever 24 is pressed downward and rotated counterclockwise in the disc mounted state shown in FIG. 3, the engaging portion of the upper edge of the eject lever 24 is engaged.
24c pushes the pin 15a of the chuck arm 15 upward, that is, in the direction away from the tray, and the disk D becomes free. When the pin 15a of the chuck arm 15 is pushed upward, the pin 15a
As the lock lever 20 is rotated clockwise, the engaging arm 20a is separated from the protrusion 20a of the tray 2 and the locked state of the tray 2 is released. You. However, at the same time, the engaging portion 24 of the eject lever 24
Since the position b is opposed to the protrusion 2c of the tray 2 and is locked, the tray 2 is held at the storage position as it is,
Do not move outside the main unit. This state is shown in FIG.

The eject lever 24 is further pressed, and the pin 15a of the chuck arm 15 is moved to the lock lever 20 as shown in FIG.
Completely over the hook 20b of the lock lever 20 and the hook 20b of the lock lever 20.
When pushed up to the upper lock position, the lock lever
20 rotates counterclockwise to lock the pin 15a to the hook 15a.

At this time, the eject lever 24 is at a position where the engagement portion 24b is disengaged from the engagement state with the projection 2c on the side surface of the tray 2 and is separated upward, and the tray 2 is released from its holding state at the disk mounting position, and The disc is ejected to the outside of the player body by 11 and returns to the disc attaching / detaching state shown in FIG.

In other words, the chuck arm is also
Until the lock lever 20 locks the upper position of the tray 15, the operation timing of the tray 2 is ensured so that the tray 2 is not held and discharged in the storage position.
