[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording medium mounting apparatus, and more particularly to a recording medium mounting apparatus mounted on a disk device or the like for transporting a recording medium (disk) between a storage position and a discharge position.

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-ROM drive) built in the device has been developed so that it can be incorporated in a miniaturized notebook computer or the like. Further, the disk device is provided with a recording medium mounting device for moving the disk between a storage 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 configured to move the tray to a disk storage position in the chassis or to a discharge position outside the chassis by manually operating the above-described motor and transmission mechanism is unnecessary. Is being developed.

FIG. 18 shows a disk device 100 of this type. The recording medium mounting device mounted on the disk device 100 includes a tray 102 on which a disk (not shown) is mounted and which is cut out on one side so that a part of the disk protrudes, And a chassis 110 that movably holds the 102.

More specifically, the tray 102 is moved by the guide rail mechanism 104 with respect to the chassis 110 to a position where the disk is ejected (a position where the disk is mounted on and dismounted from the tray 102) and a storage position (where the tray 102 is stored in the chassis 110). (Position to be stored in the unit 103).

The tray 110 is provided on the chassis 110.
Is provided in the storage position, a cover portion 110a is provided for storing a portion of the disk protruding from the tray.
With this configuration, the width of the tray 102 can be reduced, and the size of the disk device can be reduced.

An optical pickup 105 and a turntable 106 are provided on a tray 102.
Therefore, the printed circuit board 12 disposed on the chassis 110
2 (Various electronic components for reproduction processing are mounted)
, Optical pickup 105 and turntable 10
6 is electrically connected by an FPC (flexible printed circuit board) 109.

By the way, when the disk is stored in the storage position and the reproducing process is performed, if the disk is easily distorted, a good reproducing process cannot be performed. 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 at the storage position, the coil spring 126 provided on the chassis 110 is pressed by the tray 102 and is in an extended 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.

Is pressed, the lock arm 107 rotates, and the engagement between the lock claw 107a and the lock pin 119 is released. As a result, the lock of the tray 102 by the lock arm 107 is released, and the tray 102 can be moved in the arrow X1 direction in the figure.

Further, since the coil spring 126 is extended when the tray 102 is at 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,

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.

The emergency lock release mechanism having the above-described structure is configured such that when the recording medium mounting device is in an emergency state, the tray 102 by the lock arm 107 is used.
It has the function of unlocking. That is, when the recording medium mounting device is in the emergency state, the operator inserts a thin rod-shaped body from the ejection hole 121 and moves the emergency rod 120 in the arrow X2 direction in the figure.

As described above, the emergency rod 120 is used.
The end in the direction of the arrow X2 in the drawing is configured to face the end 123a of the emergency lever 123. Therefore, when the emergency rod 120 moves in the direction of arrow X2 in the figure, the emergency lever 1
Reference numeral 23 rotates around the support shaft 124 in the counterclockwise direction in the figure.

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.

As described above, the light from the LED 40 is
1, the light is guided into the eject bar 22A and travels in the eject bar 22A in the direction of arrow X1 in the figure. Therefore, the operator can see the light of the LED 40 from the operation / light emitting unit 30. The LED 40 is controlled by the system controller 61 so as to be turned on when the reproduction process is being performed on the disk 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.

By providing the LED 40 on the printed circuit board 13 disposed on the chassis 10 as described above, the number of wires for electrically connecting the chassis 10 and the tray 2 can be reduced, and the wiring of the FPC 15 can be reduced. The number can be reduced. The printed circuit board 13 has an LED 4
Although a drive circuit for driving the LED 0 is provided, by disposing the LED 40 on the printed circuit board 13 provided with the drive circuit, it is not necessary to consider the attenuation of the LED drive current, and the luminous efficiency of the LED 40 is 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 generated between the LED 114 and the operator, thereby causing the electronic components disposed in the disk device 1A to be discharged. May be damaged (see FIG. 18). However, LED4
0 is disposed on the chassis 10 side, so that the LED 40
And the operation position of the eject bar 22A by the operator (that is,
The operation / light emitting unit 30) can be largely separated. As a result, it is possible to prevent static electricity from being generated between the LED 40 and the operator.
It is possible to prevent the electronic components disposed in A from being damaged by static electricity.

Further, the side edge of the printed circuit board 13 is
Along with D40, a tray switch 41 and an eject switch 42 are arranged in rows in the directions of arrows X1 and X2. Each of the switches 41 and 42 is a so-called normally-off ON / OFF switch.
An OFF switch, which is connected to the system controller 61 as described above (see FIG. 5). Each of the switches 41 and 42 is configured to engage with the end 28 of the eject bar 22 </ b> A provided on the tray 2 as the tray 2 moves.

Specifically, in a state where the tray 2 is located at the storage position and locked as shown in FIG. 2, the eject rod provided on the tray 2 is enlarged as shown in FIG. The end 28A of 22A is configured to engage and operate a tray switch 41.

That is, when the tray 2 is located at the storage position and the lock mechanism 9 locks the tray 2, the tray switch 41 is closed (ON). However, in this stored state, the eject switch 42 is not engaged with the eject bar 22A, and is in an opened (OFF) state where it is not operated. The system controller 61 detects that the tray switch 41 is in the closed (ON) state, whereby the tray 2 is located at the storage position, and the lock mechanism 9 locks the tray 2. Recognize that.

On the other hand, in order to eject (eject) the tray 2 from the chassis 10 in the tray storage state shown in FIG. 2, the operator moves the eject rod 22A to the arrow X2 in the figure.
Push operation in the direction. As described above, in the tray storage state, the tray 2 is fixed to the chassis 10 by the lock mechanism 9, but the eject bar 22A is
It is configured to be movable with respect to. Thus, when the operator presses the operation / light emitting unit 30, the eject bar 22A moves in the direction of the arrow X2 in the figure.

FIG. 3 shows that the ejection rod 22A is indicated by an arrow X in the figure.
The eject operation state moved in two directions is shown. In the eject operation state, the end 28 of the eject bar 22A is engaged with the eject switch 42 as shown in an enlarged manner in FIG. As a result, the eject switch 42 is closed (ON). At this time, as shown in the figure, the tray switch 41 is kept closed (ON) by the eject bar 22A.
Therefore, the system controller 61 detects that the tray switch 41 is closed (ON) and the eject switch 42 is also closed (ON), so that the operator issues an ejection instruction to pull out the tray 2. Recognize that has been done. The ejection state of the tray 2 shown in FIGS. 1 and 4 can be detected when both the tray switch 41 and the eject switch 42 are open (OFF).

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

First, the operation of moving the tray 2 from the discharge position shown in FIG. 1 to the storage 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 ejection rod 22A is urged in the direction of the arrow X1 in the figure by the spring force of the coil spring 36, but further movement is restricted by the contact of the locking projection 33 with the boss 38. In this state, the operation / light emitting unit 30 is in a state of protruding slightly from the front bezel 11.

When the tray 2 is moved to the storage position, as shown in FIG. 2, the lock pins 23 provided on the tray 2 are locked by the lock arms 20 constituting the lock mechanism 9.
A lock claw 24 is engaged. Specifically, as the tray 2 moves, the lock pin 23 engages with the lock claw 24 of the lock arm 20A, displacing the lock arm 20A clockwise. As described above, since the not-shown torsion spring is provided on the lock arm 20A, when the lock pin 23 moves to the position inside the lock claw 24 in the arrow X2 direction, the lock arm 20A is attached with the torsion spring. Displaced in the counterclockwise direction by the force, the lock pin 23 is engaged with the lock claw 24. 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.

On the other hand, when the tray 2 moves toward the storage position, the ejection rod 22A provided on the tray 2 is moved.
Also moves in the direction of arrow X2 in FIG. When the tray 2 moves to the storage position, the end 28 of the eject bar 22A operates the tray switch 41 as shown in FIG. As a result, the system controller 61 detects that the tray 2 has been stored.

At this time, the locking projection 33 formed on the eject bar 22 is in contact with the boss 38 formed on the tray 2. Therefore, when the end portion 28 operates the tray switch 41, the eject bar 22A does not move (moves with respect to the tray 2) in the direction of the arrow X1, and it is ensured that the tray 2 is in the housed state. Can be detected.

In the above storage state, the light receiving section 3
1 faces the LED 40. Therefore, when the LED 40 is turned on, the light emitted from the LED 40 is taken into the eject bar 22A from the light receiving unit 31 as described above, travels inside, and the lighting of the LED 40 can be visually recognized from the operation / light emitting unit 30. .

In the storage state, the disk device 1A
Performs a reproduction 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 processing, the operator can confirm that the disk device 1A 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 storage state shown in FIG. 2 (ejection process)
Will be described.

To pull out the tray 2 from the chassis 10, the operator presses the operation / light emitting section 30 protruding from the front bezel 11 in the direction of arrow X2 in the figure. As a result, the eject bar 22A moves in the arrow X2 direction against the elastic force of the coil spring 36, and the end 28 formed on the eject bar 22A presses the eject switch 42 as shown in FIG.

In the system controller 61, the tray switch 41 and the eject switch 42 are both closed (O
In the state N), the solenoid drive transistor 62 is driven to energize the solenoid 21. This allows
The solenoid 21 is excited, and the drive pin 21a is attracted in the direction of the arrow X1 in the figure as shown in FIG.

When the drive pin 21a is sucked as described above, the lock arm 20A rotates clockwise about the support shaft 27. According to this rotation, the lock claw 24 moves so as to be separated from the lock pin 23, and eventually the lock claw 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.

When the eject slider 16 is pressed against the tray in the housed state, the coil spring 1
Numeral 7 is in a state in which the elastic force is accumulated by being extended. Therefore, when the lock by the lock mechanism 9 is released, the eject slider 16 connected to the coil spring 17 moves the tray 2 in the direction of arrow X1 in the figure. As a result, a portion of the tray 2 on the front bezel 11 side protrudes from the chassis 10 (FIG. 4 shows this state). 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, the 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 at the storage position of the tray 2 can be performed by operating the eject bar 22A constituting the lock release mechanism. That is, it is not necessary to provide the tray 2 with the electric eject switch 117 (see FIG. 18) as in the related art. Thereby, static electricity resistance is improved, and it is possible to prevent static electricity from being generated between the operator and the electric component during operation. Therefore,
It is possible to reliably prevent the electronic components provided in the disk device 1A from being broken 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 is reduced,
Cost can be reduced.

Next, a second embodiment of the present invention will be described.

FIGS. 6 to 10 are views for explaining the configuration and operation of the disk device 1B on which the recording medium mounting device according to the second embodiment is mounted. 6 to 10, the same components as those in the first embodiment described above with reference to FIGS. 1 to 5 are denoted by the same reference numerals, and description thereof is omitted.

In the recording medium mounting apparatus according to the first embodiment described above, two switches, a tray switch 41 and an eject switch 42, are used, and the tray 2 is
Separate switches 41 and 42 have been used to detect that the ejector rod 22A has been stored in the storage position within 0 and that the ejector rod 22A has been operated by the operator.

On the other hand, in this embodiment, one tray / eject switch 43 is used to detect that the tray 2 is stored in the storage position in the chassis 10, and the eject bar 22A is operated by the operator. It is characterized in that it is configured to detect the event.

The tray / eject switch 43 is
Like the switches 41 and 42 provided in the embodiment, they are arranged on the printed circuit board 13. The tray / eject switch 43 includes a main body 43A and an arm 43B. The arm part 43B is the main body part 43A
Is displaced to three positions, and an output signal can be generated at each displaced position. That is, as the tray / eject switch 43, a three-position detection switch is used.

The arm portion 43B is indicated by an arrow D1,
Although it is configured to be movable in the direction indicated by D2, it is configured to be constantly urged in the direction of arrow D1 by a spring provided in the main body 43A.

The internal configuration of the tray / eject switch 43 will be described with reference to FIG. As shown in the figure, the tray / eject switch 43 is
3A has three terminals a to c, and the connection terminal d is changed to the terminal a by the movement of the arm 43B.
To terminal c. Also,
The terminals a to c are connected to the system controller 61 as shown in FIG.

The state in which the connection terminal d is connected to the terminal a is a state in which the arm portion 43B is displaced to the limit in the direction of the arrow D1 shown in FIGS. In this state, the arm 43B and the eject bar 22A are separated from each other. Thus, the state in which the arm portion 43B and the eject bar 22A are separated is a discharge state in which the tray 2 is discharged from the chassis 10. Therefore, when the connection terminal d is connected to the terminal a, the system controller 61 can detect that the tray 2 is in the discharge state.

The state in which the connection terminal d is connected to the terminal b is a state in which the arm 43B is substantially perpendicular to the moving direction of the tray 2 as shown in FIG. At this time, the arm 43B is connected to the ejection rod 22A disposed on the tray 2.
And is displaced in the direction of arrow D2 from the discharge state shown in FIGS. In this state, tray 2 is indicated by arrow X2.
The tray 2 is moved in the direction, and the tray 2 is locked by the lock mechanism 9. Therefore, when the connection terminal d is connected to the terminal b, the system controller 61 can detect that the tray 2 is in the housed state.

Further, when the connection terminal d is connected to the terminal c, as shown in FIG.
This is a state where it is displaced in the direction of arrow X2 by 2A. Thereby, the arm 43B is further displaced in the direction D2 than the discharge state shown in FIG. This state is
This is a state in which the operator has operated the eject bar 22A in order to eject (eject) the tray 2. Therefore, by connecting the connection terminal d to the terminal c, the system controller 61 can detect that the eject operation is performed by the operator.

Next, the operation of the lock mechanism 9 and the lock release mechanism in this embodiment will be described.

Also in this embodiment, to move the tray 2 to the storage position from the discharge state shown in FIG. 6, the operator grips the front bezel 11 and moves the tray 2 in the direction of arrow X2 in the figure. When the tray 2 is moved to the storage position, as shown in FIG. 7, the lock pins 23 provided on the tray 2 are locked by the lock arms 20 constituting the lock mechanism 9.
A lock claw 24 is engaged. As a result, 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.

On the other hand, when the tray 2 moves toward the storage position, the ejection rod 22A provided on the tray 2 is moved.
Also moves with the tray 2 in the direction of the arrow X2 in the figure, and the end 28 thereof is connected to the arm 43 of the tray / eject switch 43.
Engage with B. Then, by the time the tray 2 moves to the storage position, the arm portion 43B is moved to a position substantially perpendicular to the moving direction of the tray 2. As a result, the connection terminal d is switched from the terminal a to the terminal b in the tray / eject switch 43, so that the system controller 61 detects that the tray 2 is in the housed state.

At this time, as described above, the ejection rod 22
Is in contact with a boss 38 formed on the tray 2. For this reason, the arm 43B is reliably operated in accordance with the movement of the eject bar 22A, so that it is possible to reliably detect that the tray 2 is in the housed state. In the above-mentioned housed state, the light receiving unit 31
Opposes the LED 40, and operates the LED 4
The lighting of 0 can be visually recognized, as in the first embodiment.

Then, the tray 2 is pulled out of the chassis 10 from the storage state shown in FIG. 7 (ejection process).
Will be described. To pull out the tray 2 from the chassis 10, as in the first embodiment, the operator must use the front bezel 11.
Is pressed in the direction of arrow X2 in the figure.

By this operation, the eject bar 22A moves in the direction of the arrow X2 against the elastic force of the coil spring 36,
The end 28 formed on the ejection rod 22A is the same as that shown in FIG.
As shown in FIG. 8, the arm portion 43B of the tray / eject switch 43 is further pressed in the direction of arrow D2 (detailed in FIG. 8B). Thereby, the tray / eject switch 4
In 3, the connection terminal d is switched from the terminal b to the terminal c, so that the system controller 61 detects that the operator has performed the eject operation.

When the system controller 61 detects that the eject operation has been performed from the tray / eject switch 43, it drives the solenoid drive transistor 62 to energize the solenoid 21. Thereby, the first
The same operation as the embodiment is performed in the lock mechanism 9,
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 in the drawing (toward the discharge position).

A part of the tray 2 on the side of the front bezel 11 is protruded from the chassis 10 by the coil spring 17 (see FIG. 9). The operator grasps the portion of the tray 2 that has protruded from the chassis 10 and pulls out the tray 2 to the discharge position, whereby the tray 2 is moved to the discharge position.

As described above, also in this embodiment, since the electrical eject switch 117 is not provided on the tray 2 as in the first embodiment described above, the resistance to static electricity is improved, and the operator is not required to operate. It is possible to prevent electrostatic discharge from being generated between the electronic component and the electronic component, and it is possible to reliably prevent the electronic component from being broken. Further, by eliminating the electrical eject switch 117, it is possible to reduce the number of components of the recording medium mounting device, reduce individual defects of wiring components, and reduce the cost of the FPC 15.

Further, in the first embodiment, two switches, an eject switch 42 and a tray / eject switch 43, are provided to detect the discharge of the tray 2, the storage of the tray 2, and the like.
And the ejection operation detection is performed by a separate switch. On the other hand, in the present embodiment, the detection of the ejection of the tray 2, the detection of the storage of the tray 2, and the detection of the ejection operation can be performed by the single (one) tray / eject switch 43. Compared with the configuration of the first embodiment, the number of parts can be reduced and the cost can be reduced.

Next, a third embodiment of the present invention will be described.

FIGS. 11 to 17 are views for explaining the configuration and operation of the disk device 1C on which the recording medium mounting device according to the third embodiment is mounted. 11 to 17
Also, the same components as those in the first embodiment described above with reference to FIGS. 1 to 5 are denoted by the same reference numerals, and description thereof will be omitted.

In the recording medium mounting apparatus according to this embodiment, the eject bar 22B is arranged on the tray 2 on the side of the arrow Y1 in FIG. Thereby, the tray 2 is moved to the chassis 1
In a state where the eject rod 22B is stored in the lock mechanism 9, the eject rod 22B is close to the lock mechanism 9.

Further, a switch driving concave portion 39 (corresponding to a detected portion described in claims) is formed near the end portion 28 of the ejecting rod 22B (FIGS. 12C and 13).
(B) and FIG. 14 (B)). The switch driving recess 39 is configured to engage with the tray / eject switch 44 as described later. Further, an emergency projection 34 is formed between the locking projection 33 of the eject bar 22B and the switch driving recess 39 in the direction of the arrow Y2 in the figure.

Further, in this embodiment, the lock release arm 26 is formed on the lock arm 20B constituting the lock mechanism 9. This unlocking arm 26
As will be described later, it is configured to engage with the emergency projection 34 formed on the eject bar 22B.

Further, the tray / eject switch 44 is set to the position indicated by the arrow Y1 on the printed circuit board 13 in response to the fact that the eject bar 22B is arranged on the side of the arrow Y1 of the tray 2 in the figure.
It is arranged on the side. The tray / eject switch 44 detects the switch drive recess 39 formed on the eject bar 22B as described later, and detects discharge of the tray 2 with a single (one) switch.
It is configured to be able to perform storage detection and eject operation detection. Therefore, as with the tray / eject switch 43 of the second embodiment, the number of components can be reduced and the cost can be reduced as compared with the configuration of the first embodiment.

Next, the operation of the lock mechanism 9 and the lock release mechanism in this embodiment will be described. In the present embodiment, the tray / eject switch 44 is
By detecting the switch driving concave portion 39 formed in 2B, the detection of the ejection of the tray 2, the detection of the storage of the tray 2, and the detection of the ejection operation are performed by one switch.

This tray / eject switch 44 is
With the movement of the eject rod 22B, the switch driving recess 39
Is turned off when engaged with the eject rod 22B, turned on when engaged with a portion other than the switch driving recess 39 of the eject rod 22B, and turned off when further separated from the eject rod 22B. . Therefore, the system controller 61 sets the tray / eject switch 44
The tray 2 is locked and unlocked by detecting ON / OFF changes (output changes) of the tray 2. FIG. 17 shows a lock and unlock processing program executed by the system controller 61 based on the output of the tray / eject switch 44 (abbreviated as SW 44 in FIG. 17).

Hereinafter, a specific operation will be described. In order to move the tray 2 to the storage position from the discharge state shown in FIG. 11, the operator grips the front bezel 11 and moves the tray 2 in the arrow X2 direction in the figure. When the tray 2 is moved to the storage position, as shown in FIG. 12, the lock pin 23 provided on the tray 2 is moved to the lock arm 20A.
With the lock claw 24 of the first embodiment. As a result, 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.

On the other hand, when the tray 2 moves toward the storage position, the ejection rod 22B provided on the tray 2 is moved.
Also moves with the tray 2 in the direction of arrow X2 in the figure, and as shown in FIG. 12, the end 28 engages with the tray / eject switch 44 (detailed in FIG. 12C). Thereby, the tray / eject switch 44 changes from the OFF state to the ON state.

The system controller 61 detects that the tray / eject switch 44 has been turned on at step 10 (step is abbreviated as S in the figure) of FIG. Detects the status. In this storage state,
The light receiving unit 31 faces the LED 40, and the lighting of the LED 40 can be visually recognized from the operation / light emitting unit 30.
And the second embodiment.

Next, the process of ejecting the tray 2 from the chassis 10 from the storage state shown in FIG. 12 (ejection process) will be described. In order to pull out the tray 2 from the chassis 10, as in the first and second embodiments, the operator presses the operation / light emitting unit 30 protruding from the front bezel 11 in the arrow X2 direction in the figure.

By this pressing operation, the ejection rod 22B
Moves in the direction of the arrow X2 against the elastic force of the coil spring 36. Then, in the course of this movement, first, the switch driving concave portion 39 formed on the eject rod 22B is
It engages with the tray / eject switch 44 as shown in FIG. 13 (detailed in FIG. 13B).

Accordingly, the tray / eject switch 44 changes from the ON state to the OFF state, and this signal change is transmitted to the system controller 61. Therefore, in step 11 of FIG.
Makes a positive determination, and the process proceeds to step 12.

On the other hand, when the operator releases the operation of pressing the operation / light emitting unit 30, the eject bar 22B returns in the direction of arrow X1 due to the spring force of the coil spring 36, and the tray / eject switch 44 separates from the switch driving recess 39. Again, it faces the side wall of the end 28 of the eject bar 22B. As a result, the tray / eject switch 44 is turned off.
The state changes to the ON state, and this signal change is transmitted to the system controller 61. Therefore, the system controller 61 makes an affirmative determination in step 12 of FIG. 17 and the process proceeds to step 13.

In step 13, the system controller 61 brakes the disk motor 50 via the disk motor servo circuit 51 and waits for a predetermined time to elapse. The predetermined time is a time required for the turntable 6 to decelerate.

In the following step 14, the system controller 61 drives the solenoid drive transistor 62 to energize the solenoid 21 for a predetermined time. As a result, the same operation as in the first and second embodiments is performed in the lock mechanism 9, the lock of the tray 2 by the lock mechanism 9 is released, and the tray 2 is turned in the direction of arrow X1 in the drawing (toward the discharge position). It becomes movable. Further, the tray 2 jumps out of the chassis 10 by the spring force of the coil spring 17 (see FIG. 14), and the operator grips the jumped-out portion and pulls out the tray 2 to the discharge position, whereby the tray 2 reaches the discharge position. Be moved.

As described above, also in this embodiment, as in the first and second embodiments, the resistance to static electricity is improved, and the occurrence of electrostatic discharge between the operator and the electric components during operation is prevented. Thus, the electronic component can be reliably prevented from being destroyed. Further, the number of components of the recording medium mounting device can be reduced, individual defects of wiring components can be reduced, and
5 can be reduced.

In this embodiment, as in the second embodiment,
With a single (single) tray / eject switch 44,
Since the detection of the discharge of the tray 2, the detection of the storage of the tray 2, and the detection of the eject operation can be performed, the number of parts can be reduced and the cost can be reduced. Further, the tray / eject switch 44 used in this embodiment is the same as that shown in FIG.
6 is a normal ON / OFF switch (two-state detection switch), and has a simpler configuration than the tray / eject switch 43 (see FIG. 10) that can detect three states used in the second embodiment. And inexpensive. Therefore, according to the present embodiment, it is possible to reduce the cost as compared with the second embodiment.

Next, an emergency operation in this embodiment will be described.

FIG. 15 shows an emergency state of the disk device 1C. The emergency state is a state in which the lock of the tray 2 cannot be released by a normal unlock operation such as ejecting the tray when the solenoid 21 cannot be driven (fail state) or when the power is off (non-energized state). It is.

In order to eject the tray 2 from the chassis 10 when the disk drive 1C is in the emergency state, as shown in FIG.
5, the operation / light emitting unit 30 is displaced in the direction of the arrow X2 in the figure more deeply than the operation at the time of normal ejection.

As described above, the ejecting rod 22B has the emergency projection 34 formed thereon, and the lock arm 20B constituting the lock mechanism 9 has the lock release arm 26 formed thereon. Further, the emergency projection 34 and the lock release arm 26 are engaged when the eject bar 22B moves to a predetermined position (the position shown in FIG. 15) in the direction of arrow X2, and the lock arm 20B is pivoted about the support shaft 27. Is rotated clockwise in the figure.

Therefore, the ejection rod 2 is
By operating the 2B deeply, the lock arm 20B engages with the lock release arm 26, and the lock arm 20B rotates clockwise in the figure. As a result, the lock claw 24 is disengaged from the lock pin 23 and the tray 2 is
Is unlocked.

As described above, in the recording medium mounting apparatus according to the present embodiment, since the eject bar 22B is also used as an emergency rod, the number of components of the recording medium mounting apparatus can be reduced. Furthermore, the hole 121 for emergency which was conventionally required (see FIG. 1)
8) can be eliminated, so that static electricity can be prevented from being discharged into the inside of the device through the emergency hole 121.

In the above embodiment, the disk device is described as an example of the electronic device on which the recording medium mounting device is provided. However, the application of the present invention is not limited to this. The present invention can be widely applied to a magnetic disk device or a magneto-optical disk device.

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

According to the first aspect of the present invention, it is not necessary to dispose an electric switch on the movable unit, and the static electricity resistance can be improved. Also, no static electricity is generated between the operator and the detecting means, and it is possible to prevent the electronic components provided in the recording medium mounting device from being destroyed.

According to the second aspect of the present invention, the first state and the second state can be obtained by a single (one) detection switch.
Can be detected together, so that the number of components can be reduced and the cost can be reduced as compared with a configuration in which the first and second states are detected by separate detection switches.

According to the third aspect of the present invention, since the detected portion formed on the operation member is detected by a single detection switch, the number of parts can be reduced as compared with a configuration in which detection is performed by a plurality of detection switches. And cost reduction can be achieved. In addition, the position detection device can use a switch having a simple configuration as the detection switch, which can also reduce the cost.

According to the fourth aspect of the present invention, it is not necessary to separately provide an ejecting operation member and an emergency operation member, and it is possible to reduce the number of components of the recording medium mounting device. .
