Description

Description: TECHNICAL FIELD The present invention relates to a cleaner for an information recording disk represented by a digital audio disk, and particularly to a manual cleaner.

[Conventional technology]

As a manual disk cleaner, a device that uses human power only as a drive source for relatively rotating the cleaning member and the disk (JP-A-60-234276),
Manual instrument-like device that manually performs all operations such as holding and wiping cleaning members (Japanese Utility Model Publication No. 61-130004)
There is.

[Problems to be solved by the invention]

In this type of disc, it is most preferable to move the cleaning member in the radial direction of the disc to perform cleaning in the direction orthogonal to the pit row.

However, conventional cleaners do not always perform ideal cleaning. Especially, in the case of a manual instrument-shaped cleaner that allows the user to freely operate the cleaning member,
Whether or not the user has knowledge of how to clean,
Alternatively, the dexterity of the hand causes a great difference in the cleaning effect. In some cases, the cleaning member is moved in the circumferential direction, which should not be performed, and at this time, a serious signal loss may occur due to the wiping marks formed on the disk surface. Also, in the case of a hand-held cleaner,
Since the wiping operation must be repeated, the work is troublesome and time-consuming.

As described above, the most problematic aspect of the manual instrument-shaped cleaner is that it is difficult to obtain a sufficient cleaning effect unless it is used properly according to the correct usage.

SUMMARY OF THE INVENTION An object of the present invention is to ensure that anyone can reliably perform cleaning with a manual instrument-shaped disk cleaner regardless of the user's knowledge of the cleaning method, usage or personal qualities.

An object of the present invention is to specify the moving direction of the cleaning member in the radial direction of the disk so that even if a wiping mark is mistakenly made during the cleaning operation, the adverse effect thereof can be minimized. It is in.

An object of the present invention is to make cleaning work easier and quicker.

On the mounting portion 15, a hooking piece 16 is provided in a projecting manner corresponding to the step portion 8 and the engaging groove 9 of the holder 5, and a retaining rib 17 having a semicircular cross section is formed. Mounting part as shown in Fig. 2
The arm 15 is formed so as to be inclined by an angle θ with reference to the plate surface of the arm 13. Incidentally, FIG. 4 shows only two arms 13.

The cleaning pad 14 is made of felt, non-woven fabric, chamois, sponge, or the like that allows impregnation with a cleaning liquid, and is formed in a box shape. Can be installed.

The wiper 3 is integrated with the holder 5 by covering the cap 6 with the hooking pieces 16 of the six wipers 3 hooked on the stepped portion 8 of the holder 5. In this assembled state, the upper end mounting portion 15 of each wiper 3 is in close contact with the peripheral wall of the holder 5.
Therefore, the arm 13 is inclined outwardly by an angle θ with respect to the vertical line. As shown in the enlarged view of FIG.
The retaining rib 17 of is fitted into the engaging groove 9 while being sandwiched between the holder 5 and the cap 6, and at the same time, the engaging rib of the cap 6 is engaged.
11 engages with the groove on the outer surface of the retaining rib 17. Therefore, the cap 6 is retained in the engagement groove 9 through the retaining rib 17 in a retaining manner. The facing distance B between the cleaning pads 14 in the assembled state is set smaller than the diameter of the non-recording area 19 in the center of the disk shown in FIG. Further, the height H of the arm 13 from the disk surface is set to be slightly larger than the radial length of the disk D.

In FIG. 4, the sleeve 7 of the base body 2 is formed in a cylindrical shape that opens downward, and its lower end peripheral wall is divided by six sleeves 21 provided at equal intervals, and every other divided peripheral wall is used for retaining. To form the nail 22 of. Use this sleeve 7 for the support 4
It fits inside and supports only vertical movement.

The column 4 has a cylindrical body 23 into which the sleeve 7 is fitted, and a flange 24 protruding from the upper end of the cylindrical body 23, and is formed into a bottomed cylindrical shape that opens upward as a whole. On the lower surface of the bottom wall of the barrel 23, a shaft portion 26 that fits into the central hole 25 of the disk D is provided in a protruding manner. Three vertically long sliding windows 27 for guiding and supporting the claws 22 of the sleeve 7 are provided at three peripheral surfaces of the barrel 23. By fitting the claws 22 of the sleeve 7 into the sliding window 27 while flexibly deforming the claws 22 toward the center of the cylinder, the base body 2 is supported by the column 4 so as to be vertically movable. In this assembled state, the base 2
A compression coil type spring 28 is interposed between the inner surface of the upper wall of the sleeve 7 and the inner bottom wall of the barrel 23 in order to urge the upper part of the cylinder 7 upward.

In FIG. 2, it has a base plate 29 for supporting the disk D,
A hole 29a into which the shaft portion 26 of the support column 4 is fitted is provided in the center of this, and the mounting surface 29b of the disk D is provided on the upper surface of the base plate 29. Recesses 29c for removing the disk D are formed in several places on the outer periphery of the mounting surface 29b.

When this is used, the disk D is placed on the flat base plate 29 with the surface side of the disk D, that is, the side to which the laser light is irradiated facing upward, and the shaft portion 26 of the support column 4 is set to the central hole 25 of the disk D. And the hole 29a of the base plate 29. At this time, the shaft portion 26 is tightly fitted in the central hole 25, and the bottom wall of the cylindrical body 23 is in contact with the peripheral edge of the central hole 25 to immovably and fixedly support the disk D. Further, the cleaning pad 14 of the wiper 3 is in a posture that surrounds the central hole 25 in the non-recording area 19.

The cleaning pad 14 is impregnated with the cleaning liquid, or the traces of the cleaning liquid circulated on the disk surface and the substrate 2 are pressed against the disk D against the urging force of the spring 28. Due to this pressing force, the base body 2 descends along the support column 4 via the sleeve 7, and the arm 13 of each wiper 3 is moved.
Apply buckling deformation force to. Before the operation of the arm 13, the arm 13 is already inclined outward. Therefore, when the arm 13 receives a pressing force from the base body 2, as shown in FIG. 1, the arm 13 is flexibly deformed into a concave shape, and a component force outward in the radial direction of the disk D is generated on the cleaning pad 14 side. When this component force exceeds the frictional force of the cleaning pad 14 with the disk D, the cleaning pad 14 slides radially outward, that is, in the radial direction to wipe the disk surface. During the wiping movement, the wiping surface of the cleaning pad 14 moves from the lower surface side to the inner side surface and slides while maintaining the state of being pressed against the disk D.

The cleaning pad 14 reaches the peripheral edge of the disk D in a state where the lower surface of the holder 5 of the base body 2 is in contact with the flange 24 of the support column 4 and is regulated to move downward. When the pressing force of the base body 2 is released in this state. The base body 2 is returned to the standby position by the biasing force of the spring 28, and the arm 13 is also returned to the original standby position by its elasticity. After this, the mounting posture of the cleaner 1 is slightly shifted in the circumferential direction from the previous mounting posture, and the base body 2 is pressed again to wipe the disk surface with the wiper 3. By repeating this wiping operation several times, the entire disk surface can be cleaned. If every other six wipers 3 are impregnated with the cleaning liquid for wiping, the cleaning liquid adhering to the disk surface and the wiping trace can be removed at the same time.

[Second Embodiment] FIGS. 5 and 6 show a second embodiment of the present invention. Here, the vertical movement of the base body 2 is used to cause the wiper 3 to return to the standby position with respect to the disk D. The phase can be changed automatically.

That is, the ring 31 supporting the wiper 3 is rotatably fitted on the shaft portion 5a of the holder 5, and the ring 31 is held in the retaining shape by the peripheral edge of the cap 6 fitted on the shaft portion 5a from above. A sleeve 7 is provided so as to project downward from the holder 5, a cylindrical shaft-shaped operation member 32 is rotatably supported on the outer surface of the cylinder wall, and the ring 31 and the operation member 32 are connected by a connecting means 33 that engages with each other. It is possible to accompany it. The inner surface of the sleeve 7 is formed to have a hexagonal cross section, and by vertically fitting the sleeve 7 to a guide shaft 34 having a hexagonal cross section that is provided at the center of the inside of the column 4, the base body 2 can be moved vertically through the sleeve 7. Only freely support.

A cam surface 36 for feeding and operating projections 35 provided at several places on the lower end peripheral surface of the operating member 32 is formed in a saw-tooth shape above the inner surface of the cylindrical body 23 of the column 4. An auxiliary cam surface 37 is formed below the inner surface of the barrel 23 so as to correspond to each cam surface 36. The auxiliary cam surface 37 has a function of slightly feeding the descended protrusion 35 in the same direction as the feeding direction of the cam surface 36. In order to prevent the ring 31 from idling when the base body 2 is pressed toward the disc D,
A donut-shaped rubber plate 38 is interposed between the cap 6 and the ring 31. The spring 28 for returning the base body 2 to the return posture is a guide shaft.
It is provided between 34 and the upper wall of the sleeve 7.

The wiper 3 is an arm 13 formed by bending a metal wire into a rectangular frame shape.
And a roll-shaped cleaning pad 14 which is non-rotatably wound around and fixed to its tip, and the upper end of the arm 13 is swingably supported by a ring 31. Then, the arm 13 is urged by the spring 39 to return to the standby position.

Now, when pushing the base body 2 against the spring 28 toward the disk D side,
The arm 13 swings in the radial direction while swinging against the spring 39 to wipe the disk surface. When the cleaning pad 14 further pushes down the base 2 after reaching the peripheral edge of the disk, the projection 35 of the operating member 32 contacts the lower auxiliary cam surface 37 and is guided by the inclined surface thereof to slightly move in the circumferential direction. Moving. When the pressing force of the base 2 is released in this state, the base 2 and the arm 13 return to the standby position by the elastic force of the springs 28 and 39.

The substrate 2 further rises and returns from the state where the cleaning pad 14 has returned to the non-recorded area 19. At this time, the projection 35 contacts the upper cam surface 36, is guided by the inclined surface, and is forcibly fed in the circumferential direction. Accordingly, the wiper 3 is rotationally displaced in the circumferential direction while rising apart from the disk surface, and is sent to the next wiping position in a state where it partially overlaps the previous wiping trajectory. This feed amount is determined according to the wiping width of the cleaning pad 14. After that, the substrate 2 is pressed again to repeatedly wipe the disk surface.

[Third Embodiment] FIGS. 7 and 8 show a third embodiment of the present invention, and particularly, the pressure contact load of the cleaning pad 14 to the disk D is equalized.

Specifically, the plate thickness of the arm 13 of the wiper 3 is gradually increased from the holder 5 side toward the arm tip side. Further, a flange 41 is extended from the barrel 23 of the support column 4, and a restricting groove 42 through which each arm 13 is inserted is obliquely provided in the flange 41.

According to this, in the initial movement of the wiper 3 in the radial direction, the flexural deformation of the arm 13 is limited by the restriction groove 42. As the wiper 3 moves outward in the radial direction from this state, the arm 13 is likely to be flexibly deformed, but since the cross-sectional area of the arm 13 is gradually reduced, the deformation stress is almost constant. To maintain. Therefore, according to this embodiment, it is possible to prevent the pressure contact load of the cleaning pad 14 from abnormally increasing as the arm 13 moves in the radial direction.

In order to make the deformation stress of the arm 13 constant, the width of the arm 13 is gradually increased from the base 2 side toward the tip, or a groove or window hole for adjusting the cross-sectional area on the plate surface of the arm 13 having a constant width. You may achieve by passing through.

[Another embodiment example]

In the first embodiment, the shaft portion 26 of the support column 4 is tightly fitted in the central hole 25 of the disk D, but the present invention is not limited to this. For example, the diameter of the shaft portion 26 can be made sufficiently larger than the diameter of the central hole 25. The shaft portion 26 may be configured so that the bottom wall of the column 4 does not contact the disk surface when set small or in the fitted state.

In the first embodiment, if the mounting portion 15 is configured to be reversibly mountable, both the inner and outer surfaces of the cleaning pad 14 can be effectively used.

The support column 4 may be formed of a bellows-shaped cylindrical shaft, and in this case, the support column 4 can return to the standby position by its elasticity.

The number of wipers 3 may be one or more.

〔The invention's effect〕

In the disk cleaner of the present invention, when the column 4 is fitted in the central hole 25 of the disk D and the base 2 is pressed toward the disk D, the arm 13 of the wiper 3 moves in the radial direction to wipe the disk surface. . Therefore, regardless of the user's knowledge of the cleaning method and personal qualities such as dexterity of the hands, anyone can surely perform the cleaning. Particularly, when a plurality of wipers 3 are provided, the base body 2 is moved and guided to the support columns 4, so that an even operating force can be applied to each wiper 3 and the disk surface can be wiped evenly.

By fitting the pillar 4 into the central hole 25 of the disk D, the base body 2 and the wiper 3 are positioned on the disk D, and the transition direction of the wiper 3 is specified as the radial direction.
Even if a wiping mark is erroneously formed on the disk surface during the cleaning operation, it is possible to minimize adverse effects such as signal loss and noise generation, and cleaning can be performed in the most preferable state.

Since the cleaning can be performed only by repeatedly pressing the substrate 2 toward the disk D, it is possible to quickly perform the cleaning operation by a simple operation without paying attention to the wiping direction and the wiping range unlike the conventional cleaner. You can

According to the preferred embodiment of the present invention in which the disc D is placed on the base plate 29 or the like for cleaning, the disc D can be held by the shaft portion 26 of the support column 4, and a plurality of wipers 3 can be simultaneously emitted in the radial direction. This is advantageous in that the uneven wiping force does not act on the disc D and the disc displacement during the cleaning operation can be reliably prevented.
