[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaner for removing scratches or dust, and more particularly to a cleaner for removing scratches or dust on the surface of a disc such as a laser disc or a compact disc such as an optical disc.

[0002]

2. Description of the Related Art In recent years, discs such as laser discs and compact discs, which are optical discs, have been widely used as audio and video recording media. However, when storing and using such discs, the surface thereof is always kept flat. It is required to prevent dripping and scratching on the surface or to prevent dust and the like from being attached.

[0003] Therefore, when a disc such as a laser disc is inserted into a storage case for storage, or when used in a reproduction deck, not only does it not bend, but also it is formed on the surface. It is necessary to remove scratches or dust attached to the surface.

[0004]

The removal of scratches and dust on the surface of a disk such as a laser disk has conventionally been performed manually using a so-called cloth or the like. As a result, the wounds and dust have not been sufficiently removed.

When the disc is used with the surface scratched or dust attached, the read information is read again, or one information is skipped to read the next information. Actually, the audio or video to be reproduced is disturbed, and in the worst case, the reproduction becomes impossible.

The present invention has been made in view of such circumstances, and has as its object to facilitate the removal of scratches and dust on the surface of a disk such as a laser disk or a compact disk. It is an object of the present invention to provide a cleaner device which does not cause disturbance in reproduced audio and video, and which is optimal for enabling use of a disc for a long period of time.

[0007]

In order to achieve the above-mentioned object, one configuration of the present invention is to hold a disk detachably and rotatably in a holder having a base end pivotally attached to a casing and provided at a tip end. An arm, a rotating body for removing dust or flaws having an outer peripheral surface of a cylinder and having the outer peripheral surface of the cylinder abutting against the surface of the disk, and a drive source for rotating the rotating body about its axis. Wherein the rotating body is disposed at an eccentric position deviated from the center line of the disk. Similarly, another configuration includes an arm having a base end pivotally attached to a casing and holding a disk detachably and rotatably in a holder provided at a distal end, and a cylindrical outer peripheral surface, which is pressed against the surface of the disk. A rotating body for removing dust or scratches to be brought into contact with the tendency, and a drive source for rotating the rotating body about its axis, and the arm holds the disk horizontally and rotates in the rotation direction. Characterized in that it is arranged to be swingable. Similarly, another configuration includes an arm having a base end pivotally attached to a casing and holding a disk detachably and rotatably in a holder provided at a distal end, and a cylindrical outer peripheral surface, which is pressed against the surface of the disk. A rotating body for removing dust or flaws to be brought into contact with the tendency, and a drive source for rotating the rotating body about its axis, and the rotating body is formed into a cylindrical shape with a fiber composition. A drive shaft connected to a drive source is separably inserted into the shaft core. Similarly, another configuration includes an arm having a base end pivotally attached to a casing and holding a disk detachably and rotatably in a holder provided at a distal end, and a cylindrical outer peripheral surface, which is pressed against the surface of the disk. A rotator for removing dust or flaws to be brought into contact with the tendency, and a drive source for driving the rotator to rotate about its axis,
The base end of the arm is pivotally attached to the casing so as to be swingable and rotatable in the rotation direction, a holder is pivotally attached to the tip of the arm, and the center opening of the disc is fitted in the holder. I do. Similarly, another configuration includes an arm having a base end pivotally attached to a casing and holding a disk detachably and rotatably in a holder provided at a distal end, and a cylindrical outer peripheral surface, which is pressed against the surface of the disk. A rotating body for removing dust or scratches to be brought into contact with the tendency, and a drive source for driving the rotating body to rotate about its axis, and an abrasive between the outer peripheral surface of the cylinder and the surface of the disk Is characterized by being arranged. In the above case, when the rotating body is disposed at the eccentric position, it is preferable that a cam receiver is provided on the lower surface of the arm, and the cam receiver abuts on a rotatable cam to swing the arm.

[0008]

[0009]

[0010]

According to the above arrangement, by swinging the arm, the disk can be attached to and detached from the arm.
This makes it possible to bring the rotating body into contact with the surface of the disk in a pressing manner and release the rotating body.

When the driving source is driven in a state where the rotating body is in contact with the surface of the disk in a press contact tendency, the rotating body is rotated about its axis, and the rotating body and the wiping surface are rotated. The circumference of the outer surface of the cylinder wipes the surface of the disk.

At this time, dust adhering to the surface of the disc or scratches formed on the surface are removed, and
The disk is forcibly rotated by the rotation of the rotating body.

Therefore, the fact that the length of the rotating body is set to be longer than the information recording width and that the arm continuously swings at a small angle during the cleaning, the rotation of the disk is combined with the rotation of the disk. Removal of dust or scratches on the surface is performed evenly.

When there are a plurality of rotating bodies, that is, by setting the two rotating bodies so as to sandwich the disk from both sides, the removal of dust or scratches on both sides of the disk can be performed simultaneously. Is done.

Further, by disposing an appropriate abrasive between the outer periphery of the cylinder of the rotating body and the surface of the disk, or by changing the composition material of the rotating body, the scratch on the surface of the disk can be further improved. Can be removed by polishing.

Further, the dust removing body is replaced when it becomes impossible to perform a predetermined wiping function due to dirt or wear.

[0017]

Embodiments of the present invention will be described below with reference to the drawings.

The cleaner device according to the present invention is a device for removing dust or scratches on the surface of a disk, and is shown in FIG.
As shown in FIG. 2 and FIG. 2, the arm 1 includes a dust or scratch removing body 2 as a rotating body, and a driving source 3.
2 is housed in a casing 4 in which a base end and a drive source 3 on the right side in the figure are appropriately formed, and a distal end side and a dust or scratch removing body 2 on the left side in the figure of the arm 1 are the casing 4 It is arranged outside of.

As shown by an imaginary diagram in FIG. 2, the distal end side of the arm 1 and the dust / scratch remover 2 are covered with a lid 41 which is detachably connected to the casing 4 or the like. It may be.

Incidentally, in this embodiment, the cleaner device is set so as to be configured as a so-called single unit. Therefore, as shown in FIG. The leg members 43 are disposed at four corners at the bottom of the casing 4.

The arm 1 is formed so as to detachably and rotatably hold a disk such as a laser disk or a compact disk as an optical disk. In the illustrated example, the arm 1 holds the laser disk 5 horizontally. It is set as follows.

The arm 1 has its base end 1a (see FIG. 1) pivotally attached to a step portion 44 formed in the casing 4 in a so-called raised bottom structure. As shown, it is formed so that its tip side can swing in the rotational direction.

The swing range of the arm 1 may be regulated by any means. In the illustrated example, as shown in FIG. 1, a pin 45 standing on the step 44 and a pin 45 Pins 46 arranged at appropriate intervals to correspond to
And a stopper structure composed of the following.

The pin 46 must be disposed to prevent the arm 1 from swinging more than necessary. However, the pin 45 may be omitted.

Although not shown, the casing 4 has an opening cut out in the horizontal direction.
The base end side of the arm 1 is present in the opening, and is configured to allow the arm 1 to swing in the rotation direction.

The arm 1 has a center opening 5a (see FIG. 3) of a laser disk 5 at its tip 1b (see FIG. 2).
And a holder 11 formed to support the laser disk 5 from a so-called lower surface side.

Although not shown, the holder 11 is pivotally attached to the tip 1b of the arm 1 with an interposition of a bearing or the like, and is formed so as to enable a so-called free rotation.

Further, the arm 1 has an operation rod 12 at an end 1b of the arm 1 extending to an appropriate length in the axial direction of the arm 1.

Therefore, in the arm 1, the operating rod 1
When the holder 11 is swung in the so-called opening direction (clockwise in FIG. 1) by the action of an external force on the holder 2 and the holder 11 is located outside the so-called outside of the casing 4, the holder 11 can hold the laser disk 5. Naru.

In the arm 1, the holder 11
When the laser disk 5 is swung in a so-called closing direction (counterclockwise in FIG. 1) by an external force acting on the operating rod 12 in a state where the laser disk 5 is held, dust or scratches on the surface of the laser disk 5 are removed. The contact of the body 2 becomes possible.

In this case, the dust or scratch remover 2 is disposed at an eccentric position deviated from the center line of the laser disk 5, as shown by the imaginary line in FIG.

The dust / scratch remover 2 is formed to have a cylindrical outer peripheral surface as a wiping surface, and the cylindrical outer peripheral surface is pressed against the surface of the laser disk 5 held by the arm 1 so as to be pressed against the surface. It is set to be able to contact.

Therefore, the dust or scratch remover 2 comes into contact with the surface of the laser disk 5 in a pressing manner, so that the dust or scratch remover 2 moves on the surface of the laser disk 5,
That is, when rotating, the dust or scratch remover 2 rubs against the surface of the laser disk 5, and therefore, the dust or scratch remover 2 performs a dust wiping action or a scratch polishing action. become.

However, in the case of removing dust and removing scratches, it is preferable to select a material constituting the dust or scratch removing member 2.

Hereinafter, in this embodiment, the case of removing dust will be described in detail.

When the cylindrical outer peripheral surface of the dust or scratch remover 2 comes into pressure contact with the surface of the laser disk 5, the contact portion 2a has a band shape having an appropriate width as shown in FIG. (See the hatched portion in FIG. 3).

The wiping direction of the dust / scratch remover 2 at an arbitrary point 5b on the surface of the laser disk 5 in the contact portion 2a is determined by the rotation direction b of the dust / scratch remover 2.
And the direction of movement c of the laser disk 5 due to the rotation of the dust or flaw remover 2 and the resultant force direction d.

The resultant force direction d is the radial direction of the laser disk 5, that is, the radiation direction of the laser disk 5. Therefore, even if the wiping marks are left on the surface of the laser disk 5, the wiping marks are not removed. This corresponds to the direction in which the heads (not shown) are arranged in the reproduction deck, and this does not become an obstacle.

When the cylindrical outer peripheral surface of the dust or scratch remover 2 comes into contact with the surface of the laser disk 5 in a press-contact tendency, the tip of the contact portion 2a, which is the left end in the drawing, is shown in FIG. Thus, it is preferable that the positioning is performed so as not to contact the label 5c attached to the surface of the laser disk 5.

At this time, the tip of the contact portion 2a, which is the left end in the figure, is positioned so as to slightly protrude from the center line e of the laser disk 5, as shown in FIG. Is preferred.

As shown in FIG. 4, the dust / scratch remover 2 is formed of a fiber composition into a columnar shape for removing dust, and a drive shaft composed of a rod inserted through its shaft core. 21 (see FIGS. 1 and 2).

That is, in this embodiment, the dust / scratch remover 2 is formed by stacking so-called buffs in multiple layers and formed in a columnar shape. In this case, the outer peripheral surface of the cylinder is an effective wiping surface. It is set to function as.

The buffs constituting the dust or scratch remover 2 are formed by laminating a large number of circular fabrics cut at the center so as to have an opening through which the drive shaft 21 is inserted, and have an appropriate thickness. At the same time, a fixed portion is formed by sewing or the like from the center portion toward the outer peripheral side, and the outer peripheral side is left as a non-sewn portion with an appropriate width, and the outer peripheral surface of the non-sewn portion is made a soft wiping surface. It is formed as follows.

When forming the dust or scratch remover 2, that is, when laminating buffs in multiple layers to form a columnar shape, spacers (not shown) are appropriately interposed between the buffs. Alternatively, the softness of the outer peripheral surface of the cylinder functioning as an effective wiping surface in the dust or scratch removing body 2 may be appropriately adjusted.

The dust / scratch remover 2 is shown in the illustrated example, and it is assumed that the dust / scratch remover 2 is separably held by the drive shaft 21. This is to allow replacement or repair when the surface cannot function as an effective wiping surface due to wear or dirt.

Therefore, instead of the dust or flaw remover 2 being held detachably on the drive shaft 21 as in the illustrated example, the dust or flaw remover 2 is formed integrally with the drive shaft 21. Therefore, the dust or scratch remover 2 may be configured to be replaced together with the drive shaft 21.

As shown in FIG. 5, a pipe member 22 is previously inserted through the shaft of the dust or scratch remover 2, and the drive shaft 21 is inserted through the pipe member 22 as a guide hole. May be configured to facilitate the operation.

In this case, the both ends of the pipe member 22 are crimped, so that the dust or flaw remover 2 is formed in a cylindrical shape having a fixed shape and a self-supporting property.

Further, the refuse / scratch remover 2 is shown in FIG.
As shown in FIG. 5, a wiping member 24 formed in a sheet shape such as a brushed fiber or felt is spread on a cylindrical outer peripheral surface of a core member 23 formed of a closed cylinder made of aluminum or the like, while the axis of the core member 23 is extended. An opening 23a may be formed in the core to allow the drive shaft 21 to pass therethrough.

In this case, it is possible to reduce the total weight of the dust / scratch remover 2 and the cost.

The drive shaft 21 is connected to a drive source 3 which will be described later. In the illustrated example, the drive shaft 21 is horizontally and rotatably held by a box-shaped bracket 47 disposed in the casing 4. ing.

The drive shaft 21 has a threaded portion 21a at the tip which is the left end in FIGS. 1 and 2, and the nut 25 screwed to the threaded portion 21a removes the dust or flaw. The so-called falling off of the body 2 from the drive shaft 21 is prevented, and care is taken so that the dust or flaw remover 2 is held integrally with the drive shaft 21.

The drive shaft 21 has a gear 26 connected to a base end on the right side in the drawing, and the gear 26 is connected to a drive source 3 described later and is driven to rotate. ,
It is stated that the dust or scratch remover 2 is rotationally driven.

When the dust or flaw remover 2 is held by the drive shaft 21, the cylindrical outer peripheral surface of the dust or flaw remover 2 abuts against the surface of the laser disk 5 in a pressing manner. As a matter of course, the arrangement position is set at the box-shaped bracket 47 as a matter of course.

By the way, in this embodiment, it is assumed that the dust or flaw removers 2 are arranged in plural numbers, that is, two vertically, so as to sandwich the laser disk 5 from both sides.

The dust or flaw remover 2 disposed on the upper surface side of the laser disk 5 is disposed on the lower surface side of the laser disk 5 as it is rotated in a so-called sweeping direction. The dust or scratch remover 2 is rotated in the opposite direction with the laser disk 5 interposed therebetween.

That is, some discs such as the laser disc 5 and the compact disc are so-called single-sided discs, but many are so-called double-sided discs. This is also designed so that predetermined dust or scratches can be removed simultaneously on both sides without operating the laser disk 5 or the like upside down.

The dust or flaw remover 2 is pressed against both surfaces of the laser disk 5 in a pressing manner,
The rotation of the laser disc 5 due to the rotation of the dust or flaw removing body 2 is further reliably performed.

Therefore, it is a matter of course that the dust / scratch remover 2 is not necessarily plural but may be singular, that is, one, from the viewpoint of the present invention.

In this embodiment, the drive source 3 is constituted by an electric motor held by a bracket 48 disposed on the inner bottom of the casing 4 so as to be positioned in the box-shaped bracket 47. Thus, the drive shaft 21 inserted into the shaft core of the dust or flaw remover 2 is rotationally driven.

That is, as shown in FIG. 2, the driving source 3
A drive gear 32 connected to the output shaft 31 meshes with a gear 26 connected to the drive shaft 21 to drive the gear 26 to rotate.

When the dust / scratch remover 2 is limited to one in the upper part of FIG. 2 and the arrangement of the lower dust / scratch remover 2 in FIG. 2 is omitted. The drive gear 32 may be connected to the gear 26 of the upper drive shaft 21 via a chain or the like, or the arrangement of the lower dust or flaw remover 2 may be omitted. The connection may be made with the gear 26 of the drive shaft 21 interposed therebetween.

The cleaner device according to this embodiment is configured as described above. Further, when the surface of the laser disk 5 is wiped with the dust or flaw remover 2, the laser disk 5 is slightly angled. It is configured so that it can swing.

That is, the cleaner device according to this embodiment has a swing mechanism 6 as shown in FIGS. 1 and 2, and the swing mechanism 6 is provided with an electric motor 61 placed vertically.
And a cam 6 connected to an output shaft 62 of the electric motor 61.
3 and a cam receiver 64 with which the cam 63 abuts.

The cam receiver 64 is integrally connected to the lower surface on the distal end side of the arm 1, and is configured to move with the eccentric rotation of the cam 63.

The arm 1 is rotated when the dust or flaw remover 2 is brought into contact with the laser disk 5 to rotate.
Since the cam 63 always swings in a so-called closing direction, the stopper 64 and the arm 1 swing with the rotation of the cam 63.

As a result, when the surface of the laser disk 5 is wiped with the dust or scratch remover 2, the rocking mechanism 6 is driven, whereby the laser disk 5 is repeatedly rocked at a small angle. Thus, the wiping operation of the surface of the laser disk 5 is more evenly executed.

The abrasive formed on the surface of the laser disk 5 by appropriately disposing the abrasive between the surface of the laser disk 5 and the cylindrical outer peripheral surface of the dust or scratch remover 2 during the wiping operation. Can be polished to remove it.

The cam 63 constituting the swing mechanism 6
When the cam receiver 64 is provided, the stopper 46 (see FIG. 1) for restricting the swing of the arm 1 can be omitted.

In the cleaner device of this embodiment formed as described above, by swinging the arm 1, the laser disk 5 can be attached to and detached from the arm 1, and the laser disk 5 Dust or scratch remover 2 on the surface
Can be arranged next to each other in a pressing tendency.

When the dust or flaw remover 2 is in a state of being pressed against the surface of the laser disk 5 in a pressing manner, the drive source 3 is driven, so that the dust or flaw remover 2 is moved to its axial center. That is, it is rotated about the drive shaft 21.

As a result, the outer circumference of the cylinder serving as the wiping surface of the dust or scratch remover 2 wipes the surface of the laser disk 5 to remove dust adhering to the surface of the laser disk 5 and remove the dust from the laser disk 5. The dust or flaw removing body 2 is forcibly rotated by the rotation thereof.

Therefore, the length of the dust or scratch remover 2 is set to be larger than the recording width of the information recorded on the laser disk 5, and the arm continuously swings at a small angle during cleaning. Thus, in combination with the rotation of the laser disk 5, dust removal on the surface of the laser disk 5 is uniformly performed.

At this time, the wiping direction of the dust / scratch remover 2 includes the rotation direction b of the dust / scratch remover 2 and the moving direction c of the laser disk 5 due to the rotation of the dust / scratch remover 2. Is the resultant force direction d.

The resultant force direction d is the radial direction of the laser disk 5, that is, the radiation direction of the laser disk 5. Therefore, even if the wiping marks are left on the surface of the laser disk 5, the wiping marks are not removed. It will remain in the radiation direction on the laser disk 5.

In this case, since information is recorded on the laser disk 5 in the circumferential direction, the wiping trace only intersects the information track in the circumferential direction.

Therefore, when reproducing the sound or the image recorded on the laser disk 5, the obstruction of the wiping trace in the radial direction is small.

When the two dust or scratch removers 2 are set so as to sandwich the laser disk 5 from both sides, dust removal on both surfaces of the laser disk 5 is performed simultaneously. .

Then, an appropriate abrasive is disposed between the outer periphery of the cylinder of the dust or scratch remover 2 and the surface of the laser disk 5, or the composition material of the dust or scratch remover 2 is changed to a polishing material. In this case, the surface of the laser disk 5 can be polished, and therefore, when fine scratches are scattered on the surface of the laser disk 5, it can be removed.

The operation and effect of polishing are the same as those of dust removal as described above.

The dust / scratch remover 2 is replaced when it becomes impossible to perform a predetermined wiping or polishing function due to dirt or wear.

In the above embodiment, the arm 1 is swung in the rotational direction and the laser disk 5 is held horizontally. However, in view of the object of the present invention, Instead of the above, the arm 1 may be swung in the vertical direction or a direction close thereto, and the laser disk 5 may be held vertically or close thereto.

Further, the above description is an example in which the cleaner device according to the present invention is provided as a so-called single unit. However, according to the structure of the present invention, the cleaner device is different from other devices, For example, laser disk 5
Of course, a part of a device for reproducing the audio and video recorded in the device or a device for storing the laser disk 5 may be constituted.

[0084]

As described above, according to the present invention, the following effects can be obtained.

It is possible to remove dust or scratches from the surface of a disk such as a laser disk or a compact disk by a simple operation.

The trace of wiping or polishing by the dust or scratch remover becomes a radial direction on the surface of the disk, and only intersects with the circumferential information track recorded on the disk. And obstacles in reproducing video and images can be reduced.

Further, according to the present invention, by rotating the dust or scratch remover which is in contact with the surface of the disc in a press contact tendency, it is possible not only to remove the predetermined dust or scratch but also to rotate the disc. Since it becomes possible, there is no need to separately provide equipment for rotating the disk, and there is an advantage that the cost can be reduced by reducing the weight of the entire apparatus and the number of parts.
