2. Description of the Related Art As a storage medium for storing information such as a database and software, for example, a compact disk (12 cm in diameter) reproduced by a laser pickup is used.
Or 8 cm) is being used. Therefore, a disk device (built-in CD-R) built in a chassis (housing) so that it can be incorporated in a miniaturized notebook computer or the like.
OM drive device) is being developed. Further, the disk device is provided with a recording medium mounting device for moving the disk between a mounting position where a reproduction process is performed and a discharge position where the disk is mounted on and dismounted from the disk device.

A recording medium mounting device mounted on a general disk device drives a tray on which a disk is mounted by a motor. When the tray moves out of the chassis, the disk is mounted on a turntable in the tray. The tray is returned to the chassis by the driving force of the motor again.

However, in the above-described method of driving the tray by a motor, a motor for driving the tray and a transmission mechanism for transmitting the driving force to the tray are required, and the disk device is reduced in size and thickness accordingly. It was difficult to do so, and it could not be incorporated into the notebook PC case.

Further, the above-mentioned recording medium mounting apparatus has a configuration in which the entire disk is mounted on a disk mounting portion which is an annular concave portion with a bottom provided in a tray. Therefore, the width of the tray is set to be larger than the diameter of the disk. As a result, in the conventional disk device, the lateral width of the tray is increased, and it is difficult to reduce the size of the entire disk device.

For this reason, a disk device equipped with a recording medium mounting device that eliminates the need for the motor and transmission mechanism as described above and moves the tray to a disk storage position in the chassis or a pull-out position outside the chassis by manual operation. Is being developed.

, Optical pickup 105 and turntable 10
6 is electrically connected by an FPC (flexible printed circuit board) 109.

By the way, when the disc is mounted in the storage position and the reproducing process is performed, if the disc is easily distorted, it is impossible to perform a good reproducing process. For this reason, the recording medium mounting device is provided with a lock mechanism that locks the movement of the tray 102 when the tray 102 is located at the storage position.

The lock mechanism includes a lock arm 107,
It comprises a solenoid 108, an eject switch 117, a lock pin 119 and the like. The lock arm 107 is rotatably attached to the chassis 110, and has a lock claw 107a and a connecting portion 107b. The lock claw 107a is engaged with a lock pin 119 provided on the tray 102, and the connection portion 107b is connected to the solenoid 108.

A lock claw 107a formed on the lock arm 107 is configured to engage with the lock pin 119 when the tray 102 moves in the direction of arrow X2 in the drawing to reach the storage position, thereby locking the movement of the tray 102. ing. In this locked state, the tray 102 is
Is configured to engage with a position sensor 125 provided in the tray 102, thereby detecting that the tray 102 has reached the storage position. When the tray 102 is in the storage position, the coil spring 126 provided on the chassis 110 is pressed by the tray 102 and is in a compressed state.

On the other hand, to move the tray 102 from the storage position to the discharge position, the switch button 112 provided on the tray 102 is operated. The switch button 112 is a button hole 1 formed on the front bezel 111 of the tray 102.
13, and an eject switch 117 is provided in the tray 102 at a position opposing the switch button 112. Eject switch 117

Is turned on, the lock arm 107 rotates, and the engagement between the lock claw 107a and the lock pin 119 is released. Thereby, the tray 1 by the lock arm 107 is
02 is released, and the tray 102 is moved to the arrow X1 in the figure.
It is possible to move in the direction.

Further, since the coil spring 126 is compressed when the tray 102 is in the storage position as described above,
When the lock of the tray 102 is released, the tray 102 is pushed out in the arrow X1 direction in the figure by the elastic restoring force of the coil spring 126. Therefore, a part of the tray 102 protrudes from the chassis 110, and the operator grips the part of the tray 102 protruding from the chassis 110, pulls out the tray 102 to the discharge position, and
As a result, the tray 102 reaches the discharge position.

Also, at the side position of the switch button 112,
An LED (light emitting diode) 114 is provided. The LED 114 lights up when the disk device 100 is operating, and informs the operator that the disk device 100 is operating. Therefore, an LED hole 115 is formed in the front bezel 111,
D114 is arranged inside. LED1
14 is provided on the FPC 118, and the FPC 118,

As described above, in the conventional recording medium mounting apparatus, by operating the switch button 112, the eject switch 117 is turned on, thereby the solenoid 1 is turned on.
08 is driven to unlock the tray 102. That is, in the conventional recording medium mounting apparatus, the lock of the tray 102 is released by electric means.

However, in a configuration in which the lock of the tray 102 is released only by electric means, for example, FP
If the solenoids 108 cannot be driven because the Cs 109 and 118 are defective, the lock of the tray 102 cannot be released, and the disk is transferred to the disk drive 1.
00 can no longer be taken out.
This state is called an emergency state). For this reason,
The conventional recording medium mounting device is provided with an emergency lock release mechanism for releasing the lock of the tray 102 by the lock arm 107 even in the emergency state.

The emergency lock release mechanism includes an emergency rod 120 and an emergency lever 123. The emergency rod 120 is a rod-shaped member, and is disposed on the tray 102 so as to be movable in the directions of arrows X1 and X2 in the figure. The end of the emergency rod 120 in the direction of arrow X1 in the drawing is
Eject hole 12 formed in front bezel 111
1.

The emergency lever 123 is a substantially rectangular member, and is rotatably supported by a support shaft 124 implanted in the chassis 110. One end 123a of the emergency lever 123 is configured to face the end of the emergency rod 120 in the direction of the arrow X2 in the drawing when the tray 102 is locked at the storage position. The other end 123b of the emergency lever 123 is connected to the lock arm 107.

As described above, the emergency lever 12
As the 3 rotates, the end 123b presses the connecting portion 107b of the lock arm 107. Accordingly, the lock arm 107 is rotated clockwise in the figure by a manual operation of the operator, and the engagement between the lock pin 119 and the lock claw 107a is released. Thus, the lock of the tray 102 by the lock arm 107 can be manually released.

However, in the conventional recording medium mounting apparatus, the LED 114 is mounted on the front bezel 11.
1, the wires of the LEDs 114 need to be extended from the printed circuit board 122 provided on the chassis 110 to the front bezel 111 using the FPCs 109 and 118. Therefore, each FPC 10
The number of wirings of 9,118 increases, and the cost of each FPC 10 increases.
9,118 had to be used.

Further, since the driving circuit of the LED 114 is provided on the printed circuit board 122,
If the distance between the FPCs 109 and 11 is long,
8, the LED drive current is attenuated. Therefore,
In consideration of this attenuation, the driving circuit of the LED 114 needs to supply a high current to the LED 114, and there is a problem that current consumption increases.

Further, in the configuration in which the LED 114 serving as the light emitting means is disposed on the front bezel 111, when the operator operates the front bezel 111 or the switch button 112, the LED 114 is provided between the operator and the LED 114 via the LED hole 115. As a result, there is also a problem that an electrostatic discharge is generated and electronic components provided in the disk device 100 may be destroyed.

The present invention has been made in view of the above points, and can simplify and reduce the size of the apparatus.

Further, the wiring for the light emitting means can be allocated to another signal, and the S / N of the signal can be improved.

Further, in the conventional configuration in which the LEDs are arranged on the front of the tray, static electricity is generated between the LEDs and the operator, thereby damaging the electronic components arranged in the disk drive. There is a risk that it will. However, in the above invention, since the light emitting means is provided on the chassis side, it is possible to prevent the occurrence of electrostatic discharge between the light emitting means and the operator, and thus the electronic component provided in the disk device Can prevent damage.

And a pickup assembly 7 for moving the pickup assembly.
The optical pickup 5 irradiates the disk 3 with laser light and performs a reproduction process by receiving the reflected light.

A front bezel 11 is provided on the front of the tray 2. Therefore, this front bezel 11
Moves integrally with the tray 2 in the directions of arrows X1 and X2. In the vicinity of the end of the front bezel 11 in the direction of the arrow Y1 in the figure, a convex portion 11a protruding outward is formed, and a hole 11b (see FIG. 3) is formed in the center of the convex portion 11a. I have.

Further, on the back side of the tray 2 in the direction of the arrow Y1 in the figure, an eject bar 22 is disposed so as to extend in the directions of the arrows X1 and X2 in the figure. This eject stick 2
Reference numeral 2 denotes a part of the lock mechanism 9. still,
For convenience of explanation, the description of the eject bar 22 will be described later together with the description of the lock mechanism 9.

The tray 2 having the above structure is used for the disc 3
Is formed so that the lateral width is smaller than the outer diameter of the disk 3 so that part of the disk 3 protrudes from the tray 2. Further, in the present embodiment, when the tray 2 moves in the directions of the arrows X1 and X2, a driving means such as a motor is not used, and the tray 2 is manually moved between the drawer position and the storage position.

As a result, it is not necessary to provide the disk drive 1 with a drive mechanism (consisting of a motor and a transmission mechanism) for moving the tray 2, thereby reducing the number of parts and reducing the size of the disk drive 1. And a reduction in thickness can be achieved. Further, since a part of the disk 3 protrudes from the tray 2, when the disk 3 is mounted on and dismounted from the tray 2, the protruding portion of the disk 3 can be gripped and mounted, so that the mounting and dismounting operation can be easily performed. Can be.

Next, the chassis 10 will be described. The chassis 10 generally includes a housing-like storage section 10a in which the tray 2 is stored, and a cover section 10b that protects the disk 3 protruding from the tray 2 in the storage state.

On the other hand, the cover 10b is configured to cover the lower part of the portion of the disk 3 protruding from the tray 2. Thus, the portion of the disk 3 that is not held on the tray 2 is protected by the cover 10b.
The upper part of the portion of the disk 3 protruding from the tray 2 is protected by a top plate (not shown) mounted on the chassis 10.

The side wall 10c of the cover 10b has
A braking member 19 is provided. The braking member 19 is formed of, for example, an elastic material, and when the disc 3 in the storage position is moved toward the pull-out position, the disc 3
It is configured to be in sliding contact with the outer periphery of.

Thus, the disk 3, which has been rotating at a high speed at the storage position for the reproduction / recording process, comes into sliding contact with the braking member 19 as it moves in the direction of the arrow X1 in the drawing, and its rotation is braked. Therefore, when the disk 3 is moved from the storage position to the pull-out position, the disk 3 is always in a stopped state, thereby preventing the disk 3 from being damaged.

The chassis 10 is provided with an eject slider 16 and a coil spring 17. The eject slider 16 and the coil spring 17 are provided below the printed circuit board 13 provided on the chassis 10 and on the side in the direction of the arrow Y1 in FIG. When the tray 2 is located at the storage position, the eject slider 16 is configured to come into contact with the end of the tray 2 in the direction of the arrow X2 in the drawing and be pressed.

The eject slider 16 is always urged by a coil spring 17 in the direction of arrow X1 in the figure. Therefore, when the tray 2 is located at the storage position, the eject slider 16 is pressed by the tray 2, and the coil spring 17 accumulates elastic force.

If the tray 2 is pulled out of the chassis 10 by mistake during reproduction, the disc 3 and the components and devices constituting the disc drive 1 may be damaged. For this reason, the recording medium mounting device has a function of reproducing (that is,
A lock mechanism 9 is provided to prevent the tray 2 from being pulled out of the chassis 10 when the tray 2 is at the mounting position). Hereinafter, the lock mechanism 9 will be described in detail with reference to FIG. 3 in addition to FIGS.

The lock mechanism 9 includes a lock arm 20, a solenoid 21, an eject bar 22, a lock pin 23, and the like.

And is configured to be engaged. Further, the connection portion 25 is connected to the drive pin 21a of the solenoid 21. Further, the lock release pin 26 projects upward as shown in an enlarged manner in FIG.
And is configured to be engaged.

Lock claw 2 formed on lock arm 20
Reference numeral 4 indicates that the tray 2 moves in the arrow X2 direction in the drawing and is located at the storage position, so that the tray 2
Is configured to lock the movement of the vehicle. This prevents the tray 2 from being pulled out from the chassis 10 while the disk 3 is being played back, and protects the disk 3 and prevents damage to various devices constituting the disk device 1. can do.

When the tray 2 is located at the storage position and locked, the tray 2 is configured to engage with an ejection detection switch 41 provided on the printed circuit board 13. Thus, a control device (not shown) for controlling the drive of the disk device 1 determines whether the tray 2 is located at the storage position or the ejection position based on the signal from the eject detection switch 41. You can judge.

The eject bar 22 is disposed on the side of the tray 2 in the direction of the arrow Y1 in the figure so as to extend in the directions of the arrows X1 and X2 in the figure. The eject bar 22 has a substantially round bar shape as shown in an enlarged view in FIG. 3, and includes an operation / light emitting unit 30, a light receiving unit 31, a spring hooking unit 32, and a locking convex unit 3.
3, and the engaging step 34 are integrally formed. The eject bar 22 is formed of a material through which light can pass (for example, an acrylic resin).

The eject bar 22 having the above structure is configured to be movable in the directions of arrows X1 and X2 in the figure by a guide (not shown) provided on the tray 2. A coil spring 36 is stretched between the spring hook 32 and the spring hook 37 (planted on the tray 2), and the eject bar 22 is always moved in the direction of arrow X1 by the coil spring 36. It is being rushed.

However, the locking projection 33 formed on the ejection rod 22 is connected to the boss 38 formed on the tray 2.
, The further movement of the eject bar 22 in the direction of the arrow X1 in the figure is restricted. In this state, the operation / light emitting unit 30 formed at the end of the eject bar 22 in the direction of the arrow X1 in the drawing is the front bezel 11.
Is slightly protruded from the hole 11b formed in the hole 11b.

Accordingly, when the operator presses the operation / light emitting unit 30, the eject bar 22 moves in the direction of the arrow X 2 in the figure against the elastic force of the coil spring 36.
Note that the amount of protrusion of the operation / light emitting unit 30 from the hole 11b is:
The protrusion is set to be lower than the protrusion of the protrusion 11a formed so as to surround the hole 11b, thereby preventing the operation / light emitting unit 30 from being erroneously operated.

The light receiving section 31 is mirror-finished and formed so as to be located on the side of the eject bar 22. As shown in FIG.
When the printed circuit board 13 is
Are arranged so as to face the LED 40 disposed in the first position. Therefore, in a state facing the light receiving unit 31, LE
When D40 is turned on, the light of the LED 40 is applied to the light receiving unit 31.

When the light from the LED 40 is received by the light receiving section 31 as described above, this light is guided into the eject bar 22 and travels through the eject bar 22 in the direction of arrow X1 in the figure. Therefore, the operator operates the light of the LED 40 to operate / light the light emitting unit 3.
You can see from 0. As described above, the LED 40
Is configured to be lit when a reproduction process is being performed on the disc 3. Therefore, the operator can determine whether or not the reproduction process is being performed on the disc 3 based on whether or not the operation / light emitting unit 30 is lit.

As described above, according to this embodiment, the LEDs 40 (light emitting means) are provided on the printed circuit board 13 provided on the chassis 10, so that the number of wires for electrically connecting the chassis 10 and the tray 2 is provided. Can be reduced. That is, the number of wirings of the FPC 15 can be reduced. Therefore, when the number of wires of the FPC 15 is reduced, the FP
The cost of C15 can be reduced. In addition, LED
When the number of wirings for 40 is the same as the conventional number, it becomes possible to allocate the vacant wirings to other signals.
N can be improved.

The printed circuit board 13 is provided with a drive circuit for driving the LED 40. As in the present embodiment, the printed circuit board 13 provided with this drive circuit is provided with an LE.
By arranging the D40, it is not necessary to consider the attenuation of the LED driving current, so that the luminous efficiency of the LED 40 can be improved and the current consumption of the recording medium mounting device can be reduced.

In the conventional configuration in which the LED 114 is disposed on the front bezel 111, static electricity is discharged between the LED 114 and the operator, thereby causing the electronic components disposed in the disk drive 1 to be discharged. Is likely to be damaged as described above. However, according to this embodiment, since the LED 40 is disposed on the chassis 10 side, the LED 40 and the operator are largely separated. As a result, it is possible to prevent electrostatic discharge from being generated between the LED 40 and the operator, and thus it is possible to prevent the electronic components provided in the disk device 1 from being damaged.

Further, since the conventional LED 114 is directly mounted on the flexible and easily deformable FPC 118, the mounting reliability is low. On the other hand, in the present embodiment, since the LEDs 40 are provided on the printed board 13 which is a hard board, the mounting reliability of the LEDs 40 can be improved.

Next, the operation of the lock mechanism 9 will be described.

First, the operation of moving the tray 2 from the state at the discharge position (the state shown in FIG. 1) to the mounting position shown in FIG. 2 will be described. To move the tray 2 to the storage position, the operator grips the front bezel 11 and moves the tray 2 in the direction of arrow X2 in the figure. As a result, the tray 2 moves in the arrow X2 direction in the figure while being guided by the guide rail mechanism 4. At this time, the eject rod 22 is indicated by an arrow X in the figure.
The operation / light-emitting unit 30 is moved in one direction, and the operation / light-emitting unit 30 is
From the hole 11b.

When the tray 2 is moved to the storage position, the lock pins 23 provided on the tray 2 engage with the lock claws 24 of the lock arm 20. In this state, the tray 2 is locked to the chassis 10 by the lock mechanism 9, and the movement in the direction of arrow X1 in the figure is restricted.

When the tray 2 moves to the storage position, the tray 2 is engaged with the ejection detection switch 41, and the ejection detection switch 41 is moved to the storage device with respect to the control device of the disk device 1. Let them know. Further, the end of the tray 2 in the direction of the arrow X2 in the figure presses the eject slider 16, and the coil spring 17 urges the tray 2 through the eject slider 16 in the direction of the arrow X1 in the figure.

Here, paying attention to the eject bar 22 provided on the tray 2 in the housed state, the light receiving portion 31 of the eject bar 22 faces the LED 40 in the housed state. Therefore, when the LED 40 is turned on, the light emitted from the LED 40 is taken into the eject bar 22 from the light receiving unit 31 as described above, and travels inside, and the lighting of the LED 40 can be visually recognized from the operation / light emitting unit 30. .

In the retracted state, the eject rod 2
2 is configured to be adjacent to the lock release pin 26 formed on the lock arm 20 (detailed in FIG. 2B). Specifically, the step portion 34 for engagement is formed in a chipped shape at the end of the eject bar 22 in the direction of arrow X2 in the drawing, and the lock release pin 26 is located at the portion where the step is formed. Have been.

In the above storage state, the disk device 1 performs a reproducing process on the disk 3 placed on the tray 2. In addition, since the operation / light emitting unit 30 is turned on during the reproduction process, the operator can confirm that the disk device 1 is in the reproduction processing state by turning on the operation / light emitting unit 30.

Subsequently, the process of pulling the tray 2 out of the chassis 10 from the mounted state shown in FIG. 2 (ejection process)
Will be described.

To pull out the tray 2 from the chassis 10, the lock of the tray 2 by the lock mechanism 9 is released.
The recording medium mounting apparatus according to the present embodiment has two operation modes: a manual ejection operation for manually performing an ejection process, and a motorized ejection operation for electrically performing an ejection process.

The manual ejection operation for manually performing the ejection process is an ejection process performed by an operator. On the other hand, the electric ejection operation for performing the ejection process by electric power is an ejection process that is forcibly performed, for example, when a disc ejection command is issued from the personal computer connected to the disc device 1.

In order to release the lock of the tray 2 by the lock mechanism 9 by the manual eject operation, the operator moves the operation / light emitting unit 30 protruding from the front bezel 11 by an arrow X in the figure.
Push operation in two directions. As a result, the eject rod 22 moves in the direction of arrow X2 against the elastic force of the coil spring 36, and the engaging step 3 formed on the eject rod 22 is moved.
4 presses the lock release pin 26 of the lock arm 20.

When the engagement step 34 presses the lock release pin 26 in this manner, the lock arm 20 rotates clockwise in FIG. 4 around the support shaft 27, and as shown in FIG. 24 is detached from the lock pin 23.
As a result, the lock of the tray 2 by the lock mechanism 9 is released, and the tray 2 becomes movable in the direction of the arrow X1 (toward the discharge position) in the drawing.

Further, as described above, in the mounted state, the coil spring 17 is in a state of accumulating elastic force. Accordingly, when the lock by the lock mechanism 9 is released, the coil spring 17 connected to the coil spring 17 moves the tray 2 in the arrow X1 direction in the figure.
As a result, a part of the tray 2 on the side of the front bezel 11 protrudes from the chassis 10. The operator grips the portion of the tray 2 that has protruded from the chassis 10 and pulls out the tray 2 to the discharge position. Thereby, tray 2
Is moved to the discharge position.

As described above, in the configuration of the present embodiment, the lock by the lock mechanism 9 in the storage position of the tray 2 is performed by the operation / light emitting unit 30 of the eject rod 22 (manual operation member).
(Operation unit) can be manually operated. Therefore, the conventionally used electric eject switch 117 (see FIG. 6) can be dispensed with, so that the resistance to static electricity is improved, and static electricity is generated between the operator and the electronic components during operation. This can be reliably prevented. Therefore, it is possible to reliably prevent the electronic components provided in the recording medium mounting device from being destroyed due to the electrostatic discharge.

Also, the electric eject switch 117
As a result, the number of components of the recording medium mounting device can be reduced, and individual defects of wiring components can be reduced, so that the reliability of the recording medium mounting device can be improved. Further, since the number of wires of the FPC 15 can be reduced, the cost of the FPC 15 can be reduced.

Further, the emergency rod 120 and the emergency lever 123, which are conventionally provided in preparation for the failure of the eject switch 117, can be eliminated, thereby also reducing the number of components of the recording medium mounting apparatus. Can be. Furthermore, since the hole for emergency 121 can be eliminated, static electricity can be prevented from being discharged into the inside of the device through the hole for emergency 121.

On the other hand, as described above, in the present embodiment, the ejection rod 22 is formed in a rod shape, so that the ejection rod 22 is not obstructed by other components of the tray 2 and without increasing the size of the tray 2. 22 can be arranged on the tray 2. In this embodiment, the release of the tray 2 by the lock mechanism 9 can be performed only by operating the eject bar 22. Therefore, the lock mechanism 9 can be simplified, and the number of components of the recording medium mounting device can be reduced.

Further, in addition to the function as the lock mechanism 9 described above, the eject bar 22 also functions as an optical display member for notifying that the LED 40 is turned on. Therefore, the number of parts of the recording medium mounting apparatus can be reduced, the configuration can be simplified, and the size can be reduced.

On the other hand, to perform the ejection process by electric power, the solenoid 21 is driven. When the solenoid 21 is driven, the connection portion 25 connected to the drive pin 21a is moved in the direction of the arrow X1 in the figure, and the lock arm 20 is rotated clockwise in the figure as shown in FIG. Thereby, the lock claw 24 is disengaged from the lock pin 23, so that the tray 2 is configured to be movable. In addition, lock claw 2
The processing after the release of the lock pin 4 from the lock pin 23 is the same as the above-described manual eject operation, and the description thereof will be omitted. In the above-described embodiment, a disk device has been described as an example of an electronic device in which a recording medium mounting device is provided. However, the application of the present invention is not limited to this. Alternatively, the present invention can be widely applied to a magneto-optical disk device and the like.

According to the present invention as described above, the following various effects can be realized.

According to the first aspect of the present invention, since the light emitting means is provided on the chassis side, the number of wires for electrically connecting the chassis and the tray can be reduced, and the cost can be reduced. . Further, the wiring for the light emitting means can be allocated to another signal, and the S / N of the signal can be improved. In addition, it is possible to prevent electrostatic discharge from being generated between the light emitting means and the operator, thereby preventing the electronic components provided in the recording medium mounting device from being damaged.

According to the second aspect of the present invention, the optical display member has a function of locking / unlocking the tray as well as a function of displaying light, so that the number of parts can be reduced and the recording medium can be reduced. The configuration of the mounting device can be simplified and downsized.
