Description

Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art In recent years, disks such as laser disks and compact disks, which are optical disks, have been widely used as recording media for audio and video, and the surfaces of these disks are always kept flat during storage and use. It is required to prevent dripping and scratches on the surface thereof, or to prevent dust and the like from adhering.

Therefore, when a disc such as a laser disc is inserted into a storage case for storage or set in a reproducing deck for use, it is not bent and is formed on the surface. It is necessary to remove scratches or dust that adheres to the surface.

[0004]

By the way, the removal of scratches and dust on the surface of a disc such as a laser disc has hitherto been carried out manually by using a so-called cloth or the like, and therefore a so-called labor is required. Therefore, the scratches and dust are not removed sufficiently.

When the disc is used with the surface having scratches or dust attached, the read information is read again or one information is skipped and the next information is read. The actual situation is that the audio and video are disturbed, and in the worst case, they cannot be reproduced.

The present invention was devised in view of the above circumstances, and an object thereof is to easily enable 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 disturb the reproduced audio and video and makes it possible to use the disc for a long period of time.

[0007]

In order to achieve the above-mentioned object, the structure of the cleaner device according to the present invention has an arm for holding a disk detachably and rotatably and a cylinder outer peripheral surface. A rotary body for removing dust or scratches, the surface of which comes into pressure contact with the surface of the disk, and a drive source for rotationally driving the rotary body around its axis.

Further, specifically, it is preferable that the arm is formed so as to hold the disk horizontally and to be swingable in the horizontal direction. Further, it is preferable that the rotating body is formed of a fibrous composition in a columnar shape, and a drive shaft connected to a drive source is separably inserted into the shaft core portion thereof.

Further, it is preferable that a plurality of rotating bodies are arranged so as to sandwich the disk from both sides.

[0010]

According to the above construction, by swinging the arm, the disk can be attached to and detached from the arm, and
It is possible to bring the rotating body into contact with the surface of the disc in a pressure-contacting manner and to release it.

When the drive source is driven while the rotating body is in pressure contact with the surface of the disk, the rotating body is rotated about its axial center and becomes a wiping surface in the rotating body. The outer circumference of the cylinder wipes the surface of the disc.

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

Therefore, the length of the rotating member is set longer than the information recording width, and the arm oscillates continuously at a small angle during cleaning. Removal of dust or scratches on the surface is carried out uniformly.

When a plurality of rotating bodies are used, that is, by setting two rotating bodies so as to sandwich the disc from both sides, dust and scratches on both sides of the disc can be removed at the same time. To be done.

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

Further, the dust removing body is replaced when it becomes unable to perform a predetermined wiping function due to being soiled or worn.

[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.
As shown in FIG. 2, the arm 1 includes an arm 1, a dust / scratch remover 2 that is a rotating body, and a drive source 3.
Of the arm 1 is housed in a casing 4 in which a base end side and a drive source 3 are appropriately formed, and a left end of the arm 1 on the left side in the drawing and a dust or scratch removing body 2 are the casing 4 It is distributed outside of.

The tip side of the arm 1 and the dust or scratch remover 2 are covered with a lid 41 that is separably connected to the casing 4 as shown in an imaginary line diagram in FIG. It may be given.

Incidentally, in this embodiment, the cleaner device is set so as to be configured as a so-called single unit, and therefore, as shown in FIG. 2, the handle 42 is arranged at the upper end of the casing 4. The leg members 43 are provided at the four corners of 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 laser disk 5 is held horizontally. Is set.

The base end 1a (see FIG. 1) of the arm 1 is pivotally attached to a step portion 44 formed in the casing 4 in a so-called raised bottom structure, and is indicated by an imaginary line arrow a in FIG. As shown, the tip side is formed so as to be swingable in the rotation direction.

The swing range of the arm 1 may be regulated by any means, but in the illustrated example, as shown in FIG. 1, the pin 45 provided upright on the step portion 44 and the pin 45 are provided. Pins 46 are arranged at appropriate intervals so as to correspond to 45.
It is said that it will be restricted by a stopper structure composed of and.

The pin 46 is required to be distributed in order to prevent the arm 1 from swinging more than necessary. However, the standing of the pin 45 may be omitted.

Although not shown, the casing 4 has an opening formed by cutting out in the horizontal direction,
The base end side of the arm 1 is present in the opening so that the arm 1 can swing in the rotation direction.

The arm 1 has a central opening 5a (see FIG. 3) of the laser disk 5 at its tip 1b (see FIG. 2).
It has a holder 11 which is fitted in and supports the laser disk 5 from the so-called lower surface side.

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

Further, the arm 1 has an operating rod 12 at the tip 1b thereof which extends in 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 exposed to the outside of the casing 4 by swinging it in the so-called opening direction (clockwise in FIG. 1) by the action of an external force on the laser disk 5, the laser disk 5 can be held by the holder 11. Niru.

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

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

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

Therefore, when the dust or scratch remover 2 is pressed against the surface of the laser disk 5 in a pressure contact manner, 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 is in a state of rubbing the surface of the laser disk 5, and therefore, the dust or scratch remover 2 has a dust wiping action or a scratch polishing action. become.

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

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

When the cylindrical outer peripheral surface of the dust or scratch remover 2 is brought into contact with the surface of the laser disk 5 in a pressure contacting manner, the contact portion 2a has a strip shape having an appropriate width as shown in FIG. (See the shaded area in FIG. 3).

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

The resultant force direction d becomes the radial direction of the laser disk 5, that is, the radial direction of the laser disk 5. Therefore, even if a wiping mark remains on the surface of the laser disk 5, the wiping mark is left. This corresponds to the arrangement direction of the head (not shown) on the reproducing deck, which does not become an obstacle.

When the outer peripheral surface of the dust or scratch remover 2 is pressed against the surface of the laser disk 5 in a pressure contacting manner, the left end of the contacting portion 2a in the figure is shown in FIG. Thus, it is preferable that the laser disc 5 is positioned so as not to come into contact with the label 5c attached to the surface of the laser disc 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 project from the center line e of the laser disk 5, as shown in FIG. Is preferred.

In the case of removing dust, the dust or scratch removing body 2 is made of a fibrous composition in a columnar shape as shown in FIG. 4, and has a drive shaft formed of a rod inserted into the shaft core portion. 21 (see FIGS. 1 and 2) is said to be separably held.

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

Incidentally, the buff constituting the dust or scratch removing body 2 is formed by laminating a large number of circular cloths which are cut so as to have an opening through which the drive shaft 21 is inserted at the center, and have an appropriate thickness. At the same time, a fixed portion is formed by sewing from the central portion toward the outer peripheral side by sewing, 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. Is formed as follows.

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

In the illustrated example, the dust or scratch remover 2 is supposed to be detachably held by the drive shaft 21. This is because the wiping surface of the dust or scratch remover 2, which is the outer circumference of the cylinder, is wiped. This is because when it becomes worn or dirty and cannot function as an effective wiping surface, it can be replaced or repaired.

Therefore, instead of the dust or scratch remover 2 being separably held by the drive shaft 21 as in the illustrated example, the dust or scratch remover 2 is constructed integrally with the drive shaft 21. Therefore, the debris or scratch remover 2 may be replaced together with the drive shaft 21.

Further, as shown in FIG. 5, the dust or scratch remover 2 has a pipe member 22 inserted in advance in its shaft core portion, and the drive shaft 21 is inserted through the pipe member 22 as a guide hole. May be configured to facilitate.

In this case, both ends of the pipe material 22 are caulked, so that the dust or scratch remover 2 is formed into a columnar shape having a fixed shape and a self-supporting property.

Further, the dust or scratch remover 2 is shown in FIG.
As shown in FIG. 2, while the wiping body 24 formed in a sheet shape such as napped fibers or felt is spread on the outer peripheral surface of the core body 23 formed in a closed cylinder made of aluminum or the like, the shaft of the core body 23 is extended. The opening 23a may be opened in the core portion so that the drive shaft 21 can be inserted therethrough.

In this case, it is possible to reduce the total weight of the dust and scratch removing body 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 arranged in the casing 4. ing.

The drive shaft 21 has a thread portion 21a at the left end in FIGS. 1 and 2, and a nut 25 screwed to the thread portion 21a is used to remove the dust or scratches. It is taken into consideration that the so-called falling-off of the body 2 from the drive shaft 21 is prevented and that the dust or scratch removing body 2 is integrally held by the drive shaft 21.

Further, the drive shaft 21 has a gear 26 continuously provided on the base end side which is the right side in the figure, and the gear 26 is connected to a drive source 3 described later to be rotationally driven. ,
It is supposed that the dust or scratch remover 2 is driven to rotate.

When the dust or scratch remover 2 is held on the drive shaft 21, the cylindrical outer peripheral surface of the dust or scratch remover 2 is brought into contact with the surface of the laser disk 5 in a pressure-contacting manner. As a matter of course, the arrangement position is set at the box-shaped bracket 47 portion.

By the way, in this embodiment, a plurality of dust or scratch removers 2 are arranged so as to sandwich the laser disk 5 from both sides, that is, two dust disks or scratch removers 2 are arranged above and below.

The dust or scratch remover 2 arranged on the upper surface side of the laser disk 5 is arranged on the lower surface side of the laser disk 5 as it is rotated in the so-called sweeping direction. The dust or scratch removing body 2 is supposed to be rotated in the opposite direction with the laser disk 5 interposed therebetween.

That is, some of the disks such as the laser disk 5 and the compact disk are so-called one-sided ones, but many of them are so-called double-sided ones. Also, it is designed so that the predetermined dust and scratches can be removed simultaneously on both sides without performing the so-called turning over operation of the laser disk 5 and the like.

Then, the dust or scratch remover 2 is pressed against both surfaces of the laser disk 5 in a pressure-contacting manner.
The rotation of the laser disk 5 due to the rotation of the dust or scratch remover 2 can be more reliably performed.

Therefore, it is needless to say that the dust or scratch remover 2 may be singular, that is, one, rather than plural in view of the intention of the present invention.

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

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

If the dust or scratch remover 2 is limited to one in the upper part in FIG. 2 and the disposition of the dust or scratch remover 2 in the lower part 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 so-called idle lower portion can be simply provided by omitting the disposition of the lower dust and scratch removing body 2. The drive shaft 21 may be connected while the gear 26 is interposed.

The cleaner device according to this embodiment is configured as described above. Furthermore, when wiping the surface of the laser disk 5 with the dust or scratch remover 2, the laser disk 5 is slightly angled. It is configured so that it can be swung by.

That is, in the cleaner device according to this embodiment, as shown in FIGS. 1 and 2, the swing mechanism 6 is provided, and the swing mechanism 6 is an electric motor 61 placed vertically.
And the cam 6 connected to the 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 of the arm 1 on the tip end side, and is configured to move in accordance with the eccentric rotation of the cam 63.

Then, the arm 1 is rotated when the dust or scratch removing body 2 contacted with the laser disk 5 is driven to rotate.
Since there is always a tendency to swing in the so-called closing direction, the stopper 64 and the arm 1 are swung as the cam 63 rotates.

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, and the rocking of the laser disk 5 is repeated at a slight angle. Therefore, the wiping operation of the surface of the laser disk 5 can be performed evenly.

When the wiping operation is performed, a polishing material is appropriately distributed between the surface of the laser disk 5 and the outer peripheral surface of the dust or scratch removing body 2, so that the surface of the laser disk 5 is scratched. It is also possible to remove this by polishing.

Further, the cam 63 which constitutes the swing mechanism 6 described above.
When the cam receiver 64 with which the arm abuts is provided, the provision of 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 installed next to each other in a pressure welding tendency.

Then, when the dust or scratch remover 2 is in contact with the surface of the laser disk 5 in a pressure contacting manner, the drive source 3 is driven so that the dust or scratch remover 2 has its axial center. That is, the drive shaft 21 is rotated.

As a result, the surface of the laser disk 5 is wiped by the outer circumferential surface of the cylinder, which is the surface to be wiped in the dust or scratch remover 2, and the dust adhering to the surface of the laser disk 5 is removed, and the laser disk 5 is removed. The dust or scratch remover 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. As a result, in combination with the rotation of the laser disk 5, the dust removal on the surface of the laser disk 5 is evenly performed.

At this time, the wiping direction by the dust or scratch remover 2 is the rotation direction b of the dust or scratch remover 2, and the moving direction c of the laser disk 5 by the rotation of the dust or 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 radial direction of the laser disk 5. Therefore, even if a wiping mark remains on the surface of the laser disk 5, the wiping mark is left. The laser disk 5 remains in the radial direction.

In this case, since information is recorded on the laser disk 5 in the circumferential direction, the wiping traces only intersect the information tracks in the circumferential direction.

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

Further, when the number of the dust or scratch removers 2 is two and the laser disc 5 is set to be sandwiched from both sides, the dust removal on both sides of the laser disc 5 is simultaneously performed. .

Then, an appropriate abrasive is distributed between the outer circumference 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 used as a polishing material. By changing to, it becomes possible to polish the surface of the laser disk 5, and therefore, it becomes possible to remove fine scratches on the surface of the laser disk 5 when they are scattered.

The action and effect in the case of polishing are the same as in the case of removing dust as described above.

The dust and scratch remover 2 is replaced when it becomes dirty or worn and cannot perform a predetermined wiping or polishing function.

In the above-described embodiment, the arm 1 is configured to swing in the rotational direction and further hold the laser disk 5 horizontally. However, from the point of view of the present invention, Instead of the above, it is needless to say that 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 in a state close to the vertical direction.

In the above description, the cleaner device according to the present invention is provided as a so-called single unit. However, according to the configuration of the present invention, the cleaner device is different from the other devices. For example, laser disk 5
It goes without saying that a part of the device for reproducing the audio or video recorded in or the device for storing the laser disk 5 may be configured.

[0084]

As described above, the present invention has the following effects.

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

Sounds recorded on the disc are wiped or polished by the dust or scratch remover in the radial direction on the surface of the disc, which only intersects with the information track in the circumferential direction recorded on the disc. It is possible to reduce obstacles when playing the video.

Further, according to the present invention, by rotating the dust or scratch removing body that is pressed against the surface of the disc in a pressure contacting manner, not only the predetermined dust or scratch can be removed but also the disc can be rotated. Since this is possible, there is no need to separately equip a device for rotating the disk, and there is an advantage that the weight of the entire apparatus can be reduced and the cost can be reduced by reducing the number of parts.
