Description

Disc cleaner technology

The present invention relates to a disk cleaner for cleaning disk media such as, for example, CD, DVD, MD, and MO disks. 2. Description of the Related Art As disclosed in Japanese Patent Publication No. 8-14972 and Japanese Patent Publication No. 3-49086, for example, a conventional disk cleaner uses a pressing member (extrusion protrusion) to clean the cleaning cloth. The cleaning is performed by pressing against the reading surface of the disk and wiping off any dust on the reading surface with a cleaning cloth as the disk rotates. Such a pressing member is fixed so as not to move in the radial direction of the disk.

However, if the pressing member does not move in the radial direction of the disk while the disk rotates and performs cleaning as in the past, a large amount of dust accumulates at the contact point between the cleaning cloth and the reading surface at the fixed position. The trash is easy to be missed. In other words, in the conventional disk cleaner, when the rotation of the disk is stopped at the end of cleaning and the pressing member is separated from the reading surface, the dust is wiped in a line along the radial direction of the disk. There is a problem that such a trace is left even on the recording area of the recording medium.

Hereinafter, preferred embodiments of the present invention will be specifically described with reference to the drawings. FIG. 1 is a top view showing a main part of the first embodiment, FIG. 2 is a perspective view showing a part thereof, FIG. 3 is a side view showing a part thereof, and FIG. FIG.

The disk cleaner according to the first embodiment is a dedicated cleaner for a disk A such as a CD or a DVD, and includes a motor 10, a worm gear 1 la and a lib, a disk rotation gear 11 inside a cleaner body. c, disk Rotating belt 11 d, disk spindle 11 e, reduction gear 11 f, cartridge seal 12, transmission gear 13 a, moving belt 13 b, cleaning cloth (cleaning member) 14, winding up A bobbin 15a, 15b, a pressing member 16 and a guide opening 17 are provided. The disk A is set to the reading surface facing downward above them, and is set on the cleaner body so that the hub A 1 coincides with the disk spindle 11 e. The disc A has a range from the inner broken line A3 to the outer broken line A4 as a recording area.

Motor 10, worm gear 11 a, li, disk rotation gear 11 c, disk rotation belt 11 d, disk spindle 11 e, and reduction gear 11 f are provided at predetermined locations inside the cleaner body. Have been. Other than these, the transmission gear 13a, the moving belt 13b, the cleaning cloth 14, the winding pobins 15a and 15b, the pressing member 16 and the guide opening 17 are attached to the cleaner body. It is provided on a removable cartridge shell 12. The worm gear 11a, the disk rotation gear 11c, the disk rotation belt 11d, and the disk spindle 11e constitute a disk rotation mechanism for rotating the disk A. The worm gear 11b, the reduction gear 11f, the transmission gear 13a, the moving belt 13b, and the guide rod 17 provide a moving mechanism for moving the pressing member 16 in the radial direction of the disk A. The winding bobbins 15 a and 15 b constitute a winding mechanism for manually winding the cleaning cloth 14.

When the motor 10 is driven, the disk A rotates via the worm gear 11a, the disk rotation gear 11c, the disk rotation belt 11d, and the disk spindle 11e. At the same time, the pressing member 16 passes through the worm gear 11b, reduction gear 11f, transmission gear 13a, moving belt 13b, and guide rod 17 from the inner peripheral side along the radial direction of the disc A. It moves to the outer peripheral side. As shown by the alternate long and short dash line in FIGS. 1 and 3, when the pressing member 16 reaches a position outside the outer periphery A2 of the disk A, the drive of the motor 10 stops, and the disk A and the pressing member 16 are stopped. Stops at the same time. The pressing member 16 is set on the inner peripheral side of the disc A before cleaning is started. The motor 10 has a watchdog timer function that measures the time from the start of driving to the time when the pressing member 16 reaches a predetermined position. It is controlled by a microcomputer provided with a limit switch function for directly detecting the pressing member 16 that has reached the fixed position. The gear ratio and the like are appropriately determined so that the pressing member 16 moves relatively slowly while the disk A rotates.

The cleaning cloth 14 is made of, for example, a nonwoven fabric. The cleaning cloth 14 has both ends attached to a pair of winding pobins 15a and 15b, and is stretched so as to pass through between the reading surface of the disk A and the pressing member 16. In such a cleaning cloth 14, the portion pushed out to the disk A side by the pressing member 16 comes into contact with the reading surface, and the contact portion wipes off dust on the reading surface. When one of the unwinding bobbins 15a and 15b is rotated by hand, an unused portion of the cleaning cloth 14 is fed out to a portion in contact with the reading surface, and the used portion is wound up. The winding direction of the cleaning cloth 14 is set to intersect with the direction in which the pressing member 16 moves. As shown in FIG. 4, the pressing member 16 is provided with a pad 16A made of an elastic body such as rubber at a portion where the cleaning cloth 14 is pressed. The pad 16.A makes the cleaning cloth 14 elastically contact the reading surface.

Next, the cleaning procedure will be described.

Prior to the start of cleaning, the cartridge shell 12 is removed from the cleaner body, and the pressing member 16 is set so as to be located inside the recording area inner peripheral line A3. Also, one of the take-up bobbins 15a and 1.5b is rotated, and an unused portion of the cleaning cloth 14 is drawn out. Then, mount the cartridge shell 12 inside the cleaner body, and engage the transmission gear 13a with the reduction gear 11f. Then fix the hub A 1 on the disk spindle 11 e with the reading surface facing down, and set the disk A on the cleaner body.

At the start of cleaning, the disk A rotates with the driving of the motor 10, and at the same time, the pressing member 16 starts to move from the inner peripheral side to the outer peripheral side of the disk A. At this time, a part of the cleaning cloth 14 pushed out by the pushing member 16 comes into contact with the reading surface of the disk A, and the contact portion of the cleaning cloth 14 wipes off dust on the reading surface. Then, as the pressing member 16 moves, the contact portion of the cleaning cloth 14 also Move from the inner circumference to the outer circumference of disc A. Therefore, on the reading surface, dust is continuously wiped from the inner peripheral side to the outer peripheral side.

At the end of the cleaning, the drive of the motor 10 is stopped with the pressing member 16 positioned outside the outer periphery A2 of the disk A, and the rotation of the disk A is stopped accordingly. At this time, a part of the cleaning cloth 14 pushed out by the pressing member 16 exists outside the recording area outer peripheral line A 4 of the disk A, and is no longer in contact with the reading surface. There is no accumulation of dust and no wiping marks on the recording area.

Therefore, according to the first embodiment, at the time when the rotation of the disc A is stopped and the cleaning is finished, a part of the cleaning member pushed out by the pressing member 16 as the wiping part of the dust is a recording area of the disc A. Since it is not on the upper side and does not contact the reading surface, it is possible to prevent a trace of wiping off dust over the entire reading surface of the disc A including the recording area.

Next, a second embodiment will be described. The description of the same points as in the first embodiment will be omitted.

FIG. 5 is a top view showing a main part of the second embodiment. The disk cleaner according to the second embodiment is also a dedicated cleaner for the disk A, and includes a motor 20, a pulley 21 a, a driving gear 21 b, a pulley belt 21 d, and a disk 20 inside the cleaner body. Spindle 21e, Cartridge shell 22, First and second interlocking gears 23a, 23b, worm gear 23d for pressing movement, transmission gear 23e for pressing movement, moving belt 23f, cleaning A cloth 24, a winding bobbin 25a, 25b, a pressing member 26, a guide rod 27 and the like are provided.

The motor 20, the pulley 21a, the drive gear 21b, the pulley one belt 21d, and the disk spindle 21e are provided at predetermined locations inside the cleaner body. Other first and second interlocking gears 23a, 23b, worm gear 23d for pressing movement, transmission gear 23e for pressing movement, moving belt 23f, cleaning cloth 24, winding bobbin 2 5 a, 25 b, the pressing member 26, and the guide rod 27 are provided on the cartridge shell 22. The pulley 21a, the pulley belt 21d, and the disk spindle 21e A disk rotation mechanism is configured. The driving gear 21b, the first and second interlocking gears 23a, 23b, the worm gear 23d for pressing movement, the transmission gear 23e for pressing movement, the moving belt 23f, and the guide rod 27 A moving mechanism for moving the pressing member 26 in the radial direction of the disk A is configured. The drive gear 21b, the first interlocking gear 23a, and the winding bobbins 25a, 25b constitute a winding mechanism for automatically winding the cleaning cloth 24 during cleaning.

When the motor 20 is driven, the disk A rotates via the pulley 21a, the pulley-belt 21d, and the disk spindle 21e. At the same time, the pressing member 26 includes the driving gear 21b, the first and second interlocking gears 23a, 23b, the worm gear 23d for pressing movement, the transmission gear 23e for pressing movement, and the moving belt 23f. The disk A moves from the inner peripheral side to the outer peripheral side along the radial direction of the disk A via the guide rod 27. The point that the drive of the motor 20 is stopped when the pressing member 26 reaches a position outside the outer periphery A2 of the disk A is the same as in the first embodiment. The pressing member 26 is automatically set on the inner peripheral side of the disc A by driving the motor 20 and rotating each gear in a direction opposite to the direction indicated by the arrow in the drawing before the cleaning starts. . At this time, the first and second interlocking gears 23a and 23b rotate, and the pressing and moving worm gear 23d fixed coaxially with the second interlocking gear 23b rotates, thereby causing the pressing member 26 to rotate. Moves to the left. On the other hand, the first interlocking gear 23a and the winding bobbin 25a are connected via a one-way clutch (not shown). Therefore, even if the first interlocking gear 23a rotates in the direction S opposite to the direction indicated by the arrow in the figure, the winding bobbin 25a is kept stationary without rotating. That is, one take-up bobbin 25a rotates in the same direction only when the first interlocking gear 23a rotates in the direction indicated by the arrow in the figure, and the other take-up bobbin 25b uses the cleaning cloth. It rotates by itself when 2 4 is pulled out.

The cleaning cloth 24 is similar to the above-described embodiment in that dust on the reading surface is wiped at a portion pushed to the disk A side by the pressing member 26, but one of the winding bobbins during cleaning. Since 25a rotates, unused parts are always drawn out. For this reason, the contact portion of the cleaning cloth 24 with the reading surface always moves from the inner peripheral side to the outer peripheral side of the disk A with the movement of the pressing member 26. Is a new part without dust.

Cartridge shell 2 2 force After being attached to the S-TALINA main body, immediately before cleaning, the pressing member 26 automatically moves to a position inside the recording area inner peripheral line ライン 3.

Then, when the cleaning is started, the disk A rotates with the driving of the motor 20, and at the same time, the pressing member 26 starts to move from the inner peripheral side to the outer peripheral side of the disk A. At this time, the winding bobbin 25a rotates at the same time, so that an unused portion of the cleaning cloth 24 is fed out to the contact portion with the reading surface. Therefore, on the reading surface, the contact portion of the cleaning cloth 24 continuously moves from the inner peripheral side to the outer peripheral side, and the dust is always wiped off by the unused portion to which the dust is not attached.

At the end of cleaning, the position of the pressing member 26 is located outside the outer circumference A2 of the disc A, as in the above-described embodiment, so that a dust wiping trace is left on the recording area of the disc A. It will not remain.

Therefore, the same effects as in the first embodiment can be obtained also in the second embodiment. In addition, since the cleaning cloth 24 is wound up during cleaning, a part of the new cleaning cloth 24 is always brought into contact with the reading surface, so that the dust wiping effect can be further enhanced. Even at the moment when the cleaning cloth 24 moves away from the reading surface, a small amount of dust adheres to the contact portion at that moment, so that it is possible to minimize the loss of dust.

Next, a third embodiment will be described. The description of the same points as those in the first or second embodiment will be omitted.

FIG. 6 is a perspective view showing a main part of the third embodiment, and FIGS. 7 to 11 are explanatory diagrams for explaining an operation according to the third embodiment. The disk cleaner according to the third embodiment is also a dedicated cleaner for the disk A. Inside the cleaner body, there are a pressing movement motor 30, a pressing movement disk 31, a connecting arm 32, an electric actuator 33, a support ring 34, a pressing member 35, and a cartridge processing unit 3. 6, cleaning cloth 37, take-up pobins 38a, 38b, take-up motor 39, etc. The pressing movement motor 30, the pressing movement disk 31, the connecting arm 32, the electromagnetic actuator 33, the support ring 34, the pressing member 35, and the winding motor 39 are located inside the cleaner body. It is provided at a predetermined location. The other cleaning cloth 37 and take-up pobins 38 a and 38 b are provided on the cartridge shell 36. Although not particularly shown, a dedicated motor and the like are built in the cleaner body as a disk rotating mechanism. The pressing movement motor 30, the pressing movement disk 31, the connecting arm 32, the electromagnetic actuator 33, and the support ring 34 constitute a movement mechanism for moving the pressing member 35 in the radial direction of the disk A. The winding bobbins 38a, 38b, and the winding motor 39 constitute a winding mechanism for automatically winding the cleaning cloth 37 during cleaning.

A base end of the connecting arm 32 is rotatably mounted near the outer periphery of the pressing and moving disk 31 via a pin 31a. A pressing member 35 is fixed to the distal end of the connecting arm 32. The connecting arm 32 is supported by being inserted into the support ring 34 so as to be able to move freely to some extent. The connecting arm 32 swings about the support ring 34 when the pressing and moving disk 31 rotates by driving the pressing and moving motor 30. Therefore, the pressing member 35 fixed to the distal end of the connecting arm 32 moves so as to draw an arc substantially in the radial direction immediately below the cleaning cloth 37. The electromagnetic actuator 33 displaces the support ring 34 up and down. Specifically, when the pressing member 35 moves directly below the cleaning cloth 37, the support ring 34 is pulled up to the uppermost part, whereby the pressing member 35 pushes the cleaning cloth 37 to the reading surface side. . On the other hand, when the pressing member 35 moves in a range deviated from immediately below the cleaning cloth 37, the support ring 34 is pulled down to the lowermost part, so that the cleaning cloth 37 does not contact the reading surface. State. The drive shaft of the winding motor 39 is connected to the winding pobin 38a via a connection gear 39a. Since the take-up bobbin 38a rotates during cleaning, an unused portion of the cleaning cloth 37 is always fed out. The winding direction of the cleaning cloth 37 is opposite to the direction in which the pressing member 35 moves while immediately below the cleaning cloth 37. Thus, the same part of the cleaning cloth 37 does not always become a contact part. Immediately before the start of cleaning, as shown in FIGS. 6 to 9, the pressing member 35 is located inside the recording area inner peripheral line A3 as the cleaning procedure. In addition, since the support ring 34 is located at the uppermost position, the pressing member 35 pushes a part of the cleaning cloth 37 toward the disk A, and a part of the cleaning cloth 37 contacts the reading surface of the disk A. You.

Then, when the cleaning is started by rotating the disk A, the pressing movement motor 30 is driven, and accordingly, the pressing member 35 moves along the inner circumference of the disk A along an arc-shaped locus indicated by a broken line in FIG. From the side to the outer circumference. At this time, the take-up bobbin 38a rotates at the same time, so that a new portion of the cleaning cloth 37 is always fed out to the contact portion with the reading surface.

As shown in FIGS. 10 and 11, when the pressing member 35 reaches a position outside the outer periphery A2 of the disk A, the rotation of the disk A is stopped, and the rotation of the take-up bobbin 38a is stopped. Is also stopped. As a result, no trace of dust is left on the recording area of the disc A.

Then, in order to prepare for the next cleaning, the pressing movement motor 30 is continuously driven, and the support ring 34 is located at the lowermost position. As a result, the pressing member 35 moves along the arc-shaped trajectory shown by the one-dot chain line in FIG. 7 and is separated from the cleaning cloth 37. Finally, the pressing member 35 returns to the position immediately before the start of cleaning again.

Therefore, according to the third embodiment, similarly to the second embodiment, an effect of not leaving a trace of wiping off dust and an effect of further improving the wiping effect can be obtained.

Next, a fourth embodiment will be described. The description of the same points as in the first to third embodiments will be omitted.

FIG. 12 is a top view showing the fourth embodiment, FIG. 13 is a side view thereof, and FIG. 14 'is a side view showing a main part thereof. The disk cleaner according to the fourth embodiment is also a dedicated cleaner for the disk A. Inside the cleaner body, a disc rotating motor 40a, a disc rotating belt 40b, a disc rotating shaft 40c, a stage moving motor 41a, a pulley 41b, a pulley belt 41c, a

0 Ride stage 42a, slide guide 42b, cleaning cartridge 4'3, cleaning cloth 44, take-up bobbin 45a, 45b _s pressing member 46, take-up motor 47, etc. Is provided.

Disk rotation motor 40a, disk rotation belt 40b, disk rotation shaft 40c, stage movement motor 41a, pulley 41b, pulley belt 41c, slide stage 42a, The slide guide 42b is provided at a predetermined position inside the cleaner body. The slide stage 42 a is connected to the pulley belt 41 c and is supported by a slide guide 42 b so as to be slidable along the radial direction of the disk A. Other than these, the cleaning cartridge 43, the cleaning cloth 44, the winding bobbins 45a, 45b, the pressing member 46, and the winding motor 47 are provided on the slide stage 42a. I have. In particular, the cleaning cloth 44, the winding bobbins 45a and 45b, and the pressing member 46 are provided in the cleaning cartridge 43. The cleaning cartridge 43 is fixed at a fixed position on the slide stage 42a via positioning pins and POS.

The disk rotating motor 40a, the disk rotating belt 40b, and the disk rotating shaft 40c constitute a disk rotating mechanism for rotating the disk A. The stage moving motor 41a, pulley 41b, pulley belt 41c, slide stage 42a, and slide guide 42b move the pressing member 46 in the radial direction of the disk A. Is composed. The winding bobbins 45 a and 45 b and the winding motor 47 constitute a winding mechanism for automatically winding the cleaning cloth 44 while the cleaning cloth 44 is being cleaned.

When the disk rotation motor 40a is driven, the disk A rotates via the disk rotation belt 40b and the disk rotation shaft 40c. When the stage movement motor 4 1a is driven, the slide stage 4 2a is horizontally moved in the radial direction of the disk A via the pulleys 4 1b and 4 1b, the pulley belt 4 1c, and the slide guide 4 2b. Moving. When the winding motor 47 is driven, one of the winding pobins 45 a contained in the cleaning cartridge 43 rotates, and the cleaning cloth 44 is wound. As shown in FIG. 14, the pressing member 46 is formed of a roller. The pressing member 46 is provided so as to elastically push up the cleaning cloth 44 from below via a spring 46a and a supporting member 46b. When the cleaning cloth 44 is taken up, the pressing member 46 rotates in a state of being in close contact with the cleaning cloth 44. The cleaning cloth 44 has the above-described structure in that the dust pushed out to the disk A side by the pressing member 46 wipes off dust on the reading surface, and that one of the take-up pobins 45a rotates during cleaning. This is the same as the embodiment. The control of the motors 40a, 41a, and 47 is performed in the same manner as the cleaning procedure described above, and the rotation of the disc A and the movement of the pressing member 46, and the cleaning cloth 44 are also performed. It is the same in that the winding of the data is automatically performed.

The difference from the above-described embodiment is that the cartridge 43 itself is moved from the inner peripheral side to the outer peripheral side of the disk A together with the slide stage 42a. Even in such an embodiment, there is no difference in that the pressing member 46 moves from the inner peripheral side to the outer peripheral side of the disk A. Further, since the pressing member 46 elastically presses the cleaning cloth 44 against the reading surface of the disk A, the reading surface is damaged by a relatively large and hard dust which is difficult to wipe off with the cleaning cloth 44. Sticking can be effectively prevented. As other effects, the same effects as those of the above-described embodiment can be given.

Next, a fifth embodiment will be described. The description of the same points as those in the first to fourth embodiments will be omitted.

FIG. 15 is a perspective view showing the fifth embodiment, and FIG. 16 is a sectional view thereof. The disk cleaner according to this embodiment is dedicated to the built-in disk B housed in a disk cartridge B 0 such as an MD or MO disk. The disk cartridge B 0 is set in the cleaner main body 50. After the disc cartridge B0 is set, the shirt B1 of the disc cartridge B0 is opened, so that the opening B2 faces the outside. The internal disc B is cleaned through the opening B2. For cleaning the internal disk B, cartridge shells 12, 22, 36, etc. having the same configuration as the above-described first to third embodiments are used, although not particularly shown. Cartridge cartridge The nozzles 12, 22, 36 are set upside down from the first to third embodiments so that the cleaning cloths 14, 24, 37 face the opening B 2. You. In particular, the difference from the first to third embodiments is that the cleaner main body 50 has an outer edge B 2 a of the opening B 2 and an outer periphery B 3 And a thin plate-like member 51 extending outside the disc cartridge B0 from the gap created between the two. The distal end of the plate-shaped member 51 is provided with a claw 51a that hooks on the outer edge B2a of the opening B2, and the base end thereof is rotatably connected to a shaft 5 via a hinge. Attached to 2. Such a plate-like member 51 is set such that, after opening the shirt B1 of the disc cartridge B0, a nail 51a is put on the outer edge B2a of the opening B2. After that, after setting the cartridge shells 12, 22, and 36 above the opening B 2, the internal disk B is cleaned according to the same procedure as the cleaning procedure described above.

In such a case, at the end of the cleaning, the pressing members 16, 26, and 35 are in a state of being placed immediately above the plate-shaped member 51. At this time, debris that did not fully adhere from a part of the cleaning cloth 14, 24, 37 pushed out to the internal disk B side (downward) ′ by the pressing members 16, 26, 35 spilled out. Sometimes. Even if spills occur, most of such debris is received by the plate-like member 51, and is left on the reading surface of the storage disc B including the recording area or in the disc cartridge B0. Can not be. Therefore, according to the fifth embodiment, it can be used as a device suitable for cleaning the built-in disc B such as an MD or MO disc, and the same effects as those of the above-described embodiment can be obtained.

Note that the present invention is not limited to the above embodiments.

For example, as a modified example of the first embodiment, as shown in FIGS. 1 and 7, a portion that presses the cleaning cloth 14 is made of an elastic body such as rubber, and has a somewhat pointed tip-shaped pad. 16 B may be provided on the pressing member 16. According to such a pad 16B, the cleaning cloth 14 is elastically pressed against the reading surface of the disk A while keeping the cleaning cloth 14 in line contact with the reading surface of the disk A. This makes it difficult for the cleaning cloth 44 to be wound on the cleaning cloth 44, and it is possible to effectively prevent the reading surface from being damaged by such dust. Of course, such a pad 16B can be adopted not only in the first embodiment but also in other embodiments.

As a modified example of the first and second embodiments, as shown in FIG. 18, two sets of cartridge shells 12 and 22 having the same structure are provided, and a disk A is disposed between them. It is good also as a structure which cleans both sides simultaneously. Further, as a modified example of the third embodiment, a similar configuration may be adopted as shown in FIG. In such a case, it is not necessary to repeat the disc A each time one-sided cleaning is performed, and the disc A of the double-sided type can be quickly cleaned without trouble.

In the above embodiments, the pressing members 16, 26, 35, and 46 move from the inner circumference to the outer circumference of the discs A and B.
