Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disc device and a disc loading method.

[0002]

2. Description of the Related Art Recently, mini discs (MD, Mini Dis
k) or magneto-optical disk (MO, Magnetic Optical Disk)
As described above, a recording medium in which a disc for information recording is housed in a cartridge case is widely used.

Conventionally, a disk device for reproducing / recording these recording media stores a recording medium inserted by a user in a cartridge holder by a loading roller and moves the cartridge holder to a reproducing / recording section. Then, the recording medium is mounted in the reproducing / recording unit while being housed in the cartridge holder. The reproducing / recording unit includes a drive unit for driving the disc, and a signal pickup unit for reading an information signal recorded on the disc or writing a predetermined recording signal on the disc. Drive the disk and play / record.

The loading roller described above is disclosed in, for example, Japanese Unexamined Patent Publication No. 6-141786.
It is composed of a plurality of sets of rotating rollers that come into contact with the upper surface (edge portion) of the recording medium (cartridge case). In this case, the cartridge case is given a driving force that moves back and forth by a plurality of sets of rotating rollers, and moves while sliding on the bottom surface of the cartridge holder. The contact area between the cartridge case and the bottom surface of the cartridge holder is large, and the pressing force by the rotating roller acts from the top, so the frictional force applied to the cartridge case (resistance force accompanying movement).
Grows larger. Therefore, the loading roller requires a relatively large driving force. Further, if a uniform driving force is not applied to the entire cartridge case from the loading roller, displacement and slippage easily occur and the cartridge case cannot be smoothly accommodated in the cartridge holder.

Further, for example, as disclosed in Japanese Unexamined Patent Publication No. 8-315481, when a plurality of sets of rotating rollers that are driven by contacting both side walls (edges) of the cartridge case are used as loading rollers. There is. In this case, the cartridge case is moved while being sandwiched by the plurality of sets of rotating rollers, so that the frictional force applied to the cartridge case can be suppressed to be small. However, since the contact area between the rotating roller and the side surface of the cartridge case is small, the pressure contact force of the rotating roller must be increased in order to move the cartridge case while sandwiching it. Therefore, the rotary roller requires a drive motor having a relatively large torque.

Further, since the pressure contact force of the rotating roller must be increased, wear of the rotating roller cannot be avoided,
As the number of times of use increases, displacement and slippage easily occur, which hinders smooth movement of the cartridge case. A shutter for protecting the disc housed inside is attached to the cartridge case, and a concave portion is formed on the side surface of the shutter with which an opening and closing claw for opening and closing the shutter is engaged. Therefore, the opening / closing operation of the shutter by the opening / closing claw interferes with the movement operation of the cartridge case by the rotating roller, and the shutter may not be opened / closed smoothly.

A technique for forming a loading roller by combining a rotating roller that contacts the upper surface of the cartridge case and a rotating roller that contacts one side surface of the cartridge case is disclosed in Japanese Patent Laid-Open No. 7-11116. . The control of the drive unit that drives the rotating roller and the configuration of the loading mechanism are complicated, the apparatus becomes expensive, and downsizing is difficult.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A disk device, a disk loading mechanism and a disk loading method according to embodiments of the present invention will be described below with reference to the drawings.

1A and 1B respectively show
FIG. 1 is a side view and a front view showing a schematic configuration of a disk device according to an embodiment of the present invention. The disk device 1 includes a housing 2
A first roller unit 10, a second roller unit 20, a third roller unit 30, a reproducing / recording unit 40, and a disc mounting unit (not shown).

The housing 2 has an opening on the front surface (on the left side in FIG. 1 (a)) which serves as a cartridge insertion / removal opening 3.

The first roller portion 10 moves the cartridge inserted from the insertion / removal opening 3 back and forth (left and right in FIG. 1A). The first roller unit 10 includes a rotating roller 11, two pairs of support arms 12a and 12b, a support frame 13, a spring 14, and a tension sensor 17.

The rotating roller 11 is biased upward by a spring 14 and has two pairs of support arms 12 at both ends thereof.
It is supported by a and 12b. The rotating roller 11 is
When the cartridge is inserted, it moves downward due to its thickness. The spring 14 is deformed according to the amount of movement of the rotating roller, the tension sensor 17 detects the tension generated in the spring 14, and transmits a detection signal to a roller driving unit (not shown). In response to the detection signal sent from the tension sensor, the roller driving unit transmits the driving force to the rotating roller 11 via a driving mechanism (not shown), and the rotating roller 11 rotates clockwise.

The rotating roller 11 is a member in which hard rubber is adhered to a cylindrical metal roller. The hard rubber used is
Although not particularly limited, it is desirable to have an appropriate surface hardness that does not damage the cartridge and a sliding property in which slip does not easily occur.

The two pairs of support arms 12a and 12b are rotatably attached to the rotary roller 11 (in order not to hinder the rotation of the rotary roller 11) at their one ends. Further, the guide pin 15a,
15b is arranged and slidably attached to the support frame 13 via the guide pins 15a and 15b. When the rotating roller 11 moves downward by the thickness of the cartridge, the guide pins 15a and 15b come into contact with both ends of the slide hole 16 formed in the support frame 13, so that the support arms 12a and 12b rotate. The roller 11 is supported at that position (the position moved downward by the thickness of the cartridge).

The support frame 13 is arranged on the bottom surface of the housing 2. The support frame 13 has a slide hole 16

The spring 14 is a coil spring made of metal.
The spring 14 has one end attached to the rotary roller 11 and the other end connected to the tension sensor. Spring 1
Reference numeral 4 holds the rotating roller 11 by elastically urging it upward. When the rotating roller 11 moves downward according to the thickness of the inserted cartridge, it deforms (extends) according to the amount of movement and generates tension corresponding to the amount of deformation.

The tension sensor 17 detects the tension generated in the spring 14 and sends a detection signal to the roller driving section. In response to the detection signal sent from the tension sensor 17, the roller driving section rotates the rotating roller 11 clockwise by a roller driving mechanism (not shown). Therefore, tension is generated in the spring 14 while the inserted cartridge is in contact with the rotating roller 11 (the cartridge is being moved by the rotating roller 11).
7 continues to transmit the detection signal to the roller driving unit.

When the cartridge no longer contacts the rotating roller 11, the elastic force of the spring 14 causes the rotating roller 11 to return to its original position, and the tension acting on the spring 14 disappears. Therefore, the tension sensor 17 no longer sends a detection signal to the roller driving unit, so that the rotating roller 11 stops rotating.

The second roller portion 20 includes a rotating roller 21.

The support arm 22 has one end rotatably attached to the rotary roller 21 (so as not to interfere with the rotation of the rotary roller 21). A support shaft 25 is arranged at the other end, and is rotatably attached to the support frame 13 via the support shaft 25. The support arm 22 uses a stopper mechanism (not shown) to support the support shaft 25.
It is possible to rotate only in the clockwise direction from the position shown in FIG. In addition, the support arm 22
Is urged counterclockwise by a spring 24.

The support frame 23 is arranged on the upper surface of the housing 2. The support frame 23 can be slid back and forth (left and right in FIG. 1A) by a slide mechanism (not shown). When the rotation roller 11 of the first roller unit 10 stops rotating, the control unit of the disc device 1 (not shown) starts sliding, and a predetermined position (the central portion of the disc housed in the cartridge causes reproduction / discrimination described later). (Centered with the drive head 41 of the recording unit 40)

Composed of and. The third roller portion 30 rotates clockwise while the first roller portion 10 rotates, and
When the roller unit 10 stops its rotation, it stops rotating and locks the rotary shaft of the rotary roller 31. As a result, when the movement of the cartridge by the first roller unit 10 is completed, the third roller unit 20 causes the second roller unit 20 to move.
At the same time, the cartridge is conveyed to the reproducing / recording section 40 with the cartridge being sandwiched.

Each constituent element of the third roller portion 30 has a second
The roller unit 20 has substantially the same structure as the roller unit 20. Explaining only the portion different from the second roller portion 20, the support arm 32
However, the stopper mechanism (not shown) allows the support shaft 35 to rotate only in the counterclockwise direction from the position shown in FIG. Further, the support arm 32 is biased clockwise by a spring 34. Further, the slidable support frame 33 is arranged on the lower surface of the housing 2.

The reproducing / recording unit 40 includes a drive head 41,
A spindle motor 42, a signal pickup section 43,
It is composed of a turntable 44 and a vibration isolation member 45.

The drive head 41 is a spindle motor 42.

The turntable 44 is a metal member or a synthetic resin member having appropriate rigidity. The turntable 44 includes a drive head 41, a spindle motor 42,
The signal pickup unit 43 is mounted. In the turntable 44, for example, when the disk device 1 is a vehicle-mounted disk device, the vibration applied to the disk device 1 causes the drive head 41 to drive the disk and the signal pickup unit 43.
It is fixed to the bottom surface of the housing unit 2 via a vibration isolating member 45 so as not to affect the signal read / write operation by the.

The vibration-proof member 45 is made of a vibration-damping material such as a vibration-proof rubber which itself has a vibration-damping property. Alternatively, the vibration damping member 45 may have a vibration damping mechanism such as a damper.

The disc device 1 has the recording medium, as will be described later, when the recording medium is held between the second roller portion 20 and the third roller portion 30 and is conveyed to a predetermined position. It has a shutter opening / closing mechanism for opening / closing the shutter portion. The shutter opening / closing mechanism has an opening claw that engages with an engagement groove formed on the side surface of the shutter portion of the recording medium.
As the recording medium moves, the release claw engages with the engagement groove,
The shutter section is opened, and in this state, the disk housed in the cartridge is mounted on the drive head 41 by the mounting section described above.

Next, the recording medium used in the disk device 1 will be briefly described. FIG. 2 shows a schematic configuration of a recording medium in a state where the recording / reproducing unit 40 of the disc device 1 is mounted (a shutter unit described later is opened).

The recording medium 50 is, for example, MD (mini disk, Mini Disk), MO (magneto-optical disk, Magnetic).
An information recording medium housed in a cartridge such as an optical disk. The recording medium 50 includes a cartridge 51 as a protective housing, a disc 52 on which a predetermined information signal is recorded or an information signal is recorded, and a disc 52 housed in the cartridge 51 is exposed by opening the disc 52 when necessary. The shutter portion 53 is closed to prevent dust from entering, the engaging groove 54 formed on the side surface of the shutter portion 53 and engaged with the opening / closing claw of the disk device 1, and the shutter portion 53 is opened. And an opening 55 for exposing the internal disc 52 when exposed. An opening (not shown) is formed on the back surface of the cartridge 51 so that the drive head 41 can be fitted to the disk 52.

Next, the operation of each component of the disk device 1 when the recording medium 50 is reproduced will be described. FIG. 3 is a side view of the disk device 1 showing the operation of each component when the inserted recording medium 50 is conveyed to a predetermined position. In addition, FIG. 4 is a flowchart showing the steps of the operation of each component.

The disk device 1 can be normally loaded even when the recording medium 50 is inserted at an angle (obliquely) from the horizontal direction. In particular, when used as a vehicle-mounted disc device 1, the mounting position of the disc device 1 in the vehicle compartment is limited, and the operating position is often lower than the user's eyes. In such a vehicle-mounted disc device 1, it is difficult for the user to horizontally insert the recording medium. Therefore, it is convenient that the recording medium can be normally loaded even if the recording medium is obliquely inserted. Therefore, here, the user is the recording medium 50.
Will be described as being inserted diagonally.

First, the user operates an operation button (not shown) arranged on the front surface of the casing 2 to activate the disk device 1 and bring it into a standby state. Next, the recording medium 50 is inserted into the disk device 1 through the insertion / removal opening 3 formed on the front surface of the housing 2 at a predetermined position (the recording medium 50 is the rotating roller 11 and the rotating roller). 21) to be inserted) (step S1)
01).

The rotary roller 11 of the first roller portion 10 is
As the recording medium 50 is inserted, it is pushed down.
The spring 14 deforms (expands and contracts) according to the amount of movement of the rotating roller 11 to generate tension. The tension sensor 17 includes a spring 14
The tension generated in the roller is detected and a detection signal is transmitted to the roller driving unit. The roller driving unit starts driving the rotating roller 11 in response to the detection signal sent from the tension sensor 17.

The first rotating roller 11 rotates clockwise (step S102). At this time, the rotating roller 21 of the second roller portion 20 is pressed by the elastic force of the spring 24 to the extent that no slip occurs on the contact surface with the upper surface of the recording medium 50, and contacts the recording medium 50. ing. Therefore, when the first rotating roller 11 starts rotating clockwise, the recording medium 50 moves to the right (see FIG. 3).
(In (a)). Second rotating roller 21
Starts rotating counterclockwise in response to the rightward movement of the recording medium 50. The recording medium 50 is tilted,
The recording medium 50 moves to the right until the leading end of the recording medium 50 contacts the rotating roller 31 of the third roller unit 30.

Next, when the leading end of the recording medium 50 comes into contact with the rotating roller 31, the supporting arm 3 of the third roller portion 30 is moved.
2 rotates counterclockwise, and as shown in FIG.
The rotating roller 31 contacts the lower surface of the recording medium 50 (step S103). The rotating roller 31 is held by the rotating roller 11 and the rotating roller 21 in order to hold the recording medium 50 horizontally at the contact surface between the rotating roller 31 and the lower surface of the recording medium 50 by the elastic force of the spring 34. Fifty
A pressure contact force corresponding to the sum of the rotational moments applied to is applied. Therefore, the rotation moment applied to the recording medium 50 is balanced by the rotating roller 11, the rotating roller 21, and the rotating roller 31, and thus the recording medium 50.
Returns to the horizontal state even when inserted diagonally.

The rotating roller 31 starts rotating clockwise as the recording medium 50 which has returned to the horizontal state further moves to the right (in FIG. 3B). Recording medium 5
In the case of 0, the driving force that moves to the right is transmitted from the rotating roller 11 and is fed while being guided in the horizontal direction by the rotating roller 21 and the rotating roller 31,
The movement to the right can be smoothly continued.

As the recording medium 50 moves to the right,
When the recording medium 50 is no longer in contact with the rotating roller 11 of the first roller unit 10, as shown in FIG.
The rotating roller 11 returns to the position shown in FIG. 1A by the restoring force (elastic force) of the spring 14 (step S1).
04). Since the tension generated in the spring 14 also disappears,
The tension sensor 17 stops transmitting the detection signal to the roller driving unit. The roller drive unit responds to the stop of the detection signal sent from the tension sensor 17 in response to the rotation roller 11
Is stopped (step S105).

The control unit of the disk device 1 detects that the roller drive unit has stopped, operates the rotary shaft locking mechanism of the rotary roller 21 and the rotary roller 31, and locks these rotary shafts (step S106). This allows
As shown in FIG. 3C, the rotating roller 21 and the rotating roller 31 can sandwich the recording medium 50.

Further, the second roller portion 20 and the third roller portion 30 are located at predetermined positions in the right direction on the basis of a control signal from the control portion of the disc device 1, as shown in FIG. 3 (d). Slides to (step S107). During this time, the opening claw of the predetermined shutter opening / closing mechanism engages with the engaging groove 54 formed on the side surface of the shutter portion 53 of the recording medium 50, and opens the shutter portion 53. Therefore, when the recording medium 50 moves to the position shown in FIG. 3D, the disc 52 housed in the cartridge 51 is accessed by the signal pickup unit 43 of the reproducing / recording unit 40 through the opening 55. It is possible. Further, the central portion (opening portion) of the disk 52 is
It is centered.

At this position, the recording medium 50 is pressed downward by the mounting portion (not shown), and the disk 52 fits into the drive head 41 (step S108). Recording medium 5
When 0 is mounted on the drive head 41, the second roller unit 2
The 0 and the third roller unit 30 move to the home position shown in FIG. 1A based on the control signal of the control unit of the disk device 1. The control unit of the disk device 1 drives the spindle motor 42 to rotate the disk 52 mounted on the drive head 41 at a rotation speed (frequency) for a predetermined time, and causes the signal pickup unit 43 to rotate the disk 5.
The signal recorded in the second recording pit is read, and the output of the read signal is started from a predetermined output section (step S109).

As described above, according to the embodiment of the present invention, the first roller portion 10 and the second roller portion 20 are provided.
The recording medium 50 inserted from the insertion / removal opening 3 by the loading device including the
Are conveyed to a predetermined position (the disk 52 is centered on the drive head 41). Recording medium 5 conveyed
0 is mounted on the drive head 41 by a predetermined mounting section and reproduced by the signal pickup section 43.

Since the recording medium 50 can be loaded by the three rotating rollers 11, 21, 31, the loading mechanism is simplified and the size can be easily reduced. Further, since only the rotating roller 11 of the first roller unit 10 is driven, the roller driving unit may have a small output and the control is easy. Further, since the tension sensor 17 detects that the recording medium 50 has been inserted to a predetermined position, the recording medium 50 that has been securely inserted can be loaded without causing a defective loading or the like due to incomplete insertion. can do.

The second rotary roller 21 and the third rotary roller 31 are rotatable via the supporting arms 22 and 32, respectively, and are loaded on the recording medium 50 by the springs 24 and 34. The pressure contact force is adjusted so that the rotational moment is balanced. Therefore, even when the user inserts the recording medium 50 at an angle, the user can return it to the horizontal state and then load it normally, which is convenient.

When the reproduction of the disk 52 is completed, the recording medium 50 can be ejected from the insertion / removal opening 3 by performing steps S102 to S108 in reverse. Here, at the time of discharging, in steps S102 and S103, the roller driving unit drives the rotating roller 11 counterclockwise.

The present invention is not limited to the above embodiment, and its application, modification, etc. are arbitrary. For example, the detection of the recording medium 50 inserted by the user is performed by the rotating roller 1
It has been described that the tension sensor 17 performs the measurement based on the tension generated in the spring 14 connected to No. 1. An arbitrary method is applied to the detection of the recording medium 50. For example, by arranging a physical switch connected to the spring 14,
However, the switch may be turned on when it is pushed down by the recording medium 50. Alternatively, the presence of the recording medium 50 may be directly detected by an optical sensor or the like.

In the above embodiment, the rotary roller 1
1 has been described as being biased upward by the spring 14 which is a metal coil spring. However, the spring 14
Is a member that generates an elastic force and elastically supports the rotating roller 11, and may be a mechanical member having an elastic function instead of a single member.

In the above embodiment, the rotary roller 2
It has been described that the spring 1 and the rotating roller 31 are biased counterclockwise by the spring 24 and clockwise by the spring 34, respectively. However, for example, by driving the support arms 22 and 32 with a motor, the support arms 22 and 32 are
Of the recording medium 5 of the rotating rollers 21 and 31 by adjusting the angle of
The pressure contact force with respect to 0 may be controlled.

In the above-described embodiment, it has been explained that even the recording medium 50 inserted at an angle from the horizontal state can be normally loaded. However, the displacement of the recording medium 50 (including the upper and lower directions and the left and right direction with respect to the transport direction)
In order to prevent this, the guide portion may be separately arranged. For example, as shown in FIG. 5, if the guide portion is tapered in front of the first roller portion 10, even if the recording medium 50 is slanted in the left-right direction, it can be loaded normally. Therefore, the convenience is further improved.

In the above embodiment, the rotary rollers 11, 2 are used.
It has been described that each of the rollers 1 and 31 is composed of one roller (see FIGS. 1B and 5). However, the rotary rollers 11, 21, and 31 may be composed of a plurality of rollers. For example, the rotating rollers 21 and 31 may be composed of a plurality of rollers, and these rollers may be arranged so as not to obstruct the opening and closing of the shutter portion 53 of the recording medium 50.

In the above embodiment, it is explained that the recording medium 50 is pressed downward by the mounting portion and the disk 52 is fitted into the drive head 41 in step S108. However, the method of mounting the disk 52 on the drive head 41 is arbitrary, and for example, the drive head 41 may be moved upward and fitted to the disk 52.

In the above embodiment, when the recording medium 50 is mounted on the drive head 41, the second roller portion 20 and the third roller portion 20
It has been described that the roller portion 30 moves to the home position shown in FIG. 1A based on the control signal of the control portion of the disk device 1. However, with the second roller unit 20 and the third roller unit 30 sandwiching the recording medium 50,
The disc 52 may be reproduced.

In the above embodiment, the second roller portion 20 is used.
It has been described that the third roller portion 30 and the third roller portion 30 are movable between the initial position and the predetermined position, respectively. However, the second roller unit 20 and the third roller unit 30 may be fixedly arranged in the housing unit 2. The mounting portion is the second roller portion 2
The recording medium 50 that has been sandwiched by the 0 and third roller portions 30 and has moved to a predetermined position is clamped (gripped),
The recording medium 50 may be mounted after being centered on the drive head 41.
