Description

[Detailed description of the invention] [Industrial application field] This invention relates to a cleaner for information recording disks, such as digital audio disks.
This applies especially to manual cleaners.

[Conventional technology]

A manual disk cleaner that uses human power only as a drive source to rotate the cleaning member and the disk relative to each other (Japanese Patent Application Laid-Open No. 1989-1999)
-234276 Publication) and a manual type device in which all operations such as holding and wiping the cleaning member are performed manually (Japanese Utility Model Publication No. 130004/1986).

[Problem that the invention attempts to solve]

For this type of disk, it is most preferable to move the cleaning member in the radial direction of the disk to clean the disk in a direction perpendicular to the pit rows.

However, conventional cleaners do not always perform ideal cleaning. Particularly, in the case of a manual cleaner in which the cleaning member can be freely operated by the user, the cleaning effectiveness varies greatly depending on the user's knowledge of the cleaning method. Moving the cleaning member in the circumferential direction, which should not be done in some cases,
At this time, significant signal loss may occur due to wiping marks formed on the disk surface. Furthermore, in the case of a manual cleaner, the wiping operation must be repeated, which is troublesome and time-consuming.

The purpose of this invention is to enable anyone to ideally clean a manual disk cleaner, regardless of the user's knowledge of cleaning methods.

The purpose of this invention is to make cleaning work easier and faster.

[Means for solving problems]

The disk cleaner of the present invention, for example, as shown in FIG. It is assumed that the wiper 3 is displaced in the radial direction on the disk D by the relative approach operation. The wiper 3 includes, for example, an arm 11 that is flexible and deformable, and a cleaning pad 12 that is attached to the tip of the arm 11.

[Effect]

When the cleaning pad 12 is brought into contact with the surface of the disk D and the base body 2 is moved toward the disk D, or vice versa, when the disk D is approached toward the base body 2 side, the arm 11 of the wiper 3 bends and deforms or swings. and linearly displaced on the surface of disk D. Therefore, when the base body 2 is positioned near the center of the disk D and pressed, the cleaning pad 12 moves on the surface of the disk D in the radial direction.

[Effect of idea]

According to the disk cleaner of the present invention, when the base body 2 and the disk D are moved relatively close to each other, the base body 2
Since the plurality of wipers 3 supported by the wipers 3 are moved in a direction substantially perpendicular to the approach operation direction,
By simply positioning the base body 2 near the center of the disk D and operating the two 2 and D to approach each other relatively, the wiper 3 can move the disk surface in the radial direction to perform wiping.

Therefore, irrespective of the user's knowledge of cleaning methods, an ideal system that does not cause serious damage to the disk D can be achieved by simply positioning the base 2 with respect to the disk D. Anyone can easily perform cleaning.

Since a plurality of wipers 3 simultaneously clean a plurality of locations, the cleaning work can be performed more quickly than in the conventional example, and the troublesomeness of the work can be eliminated.

[First Embodiment] FIGS. 1 to 4 show a first embodiment of the present invention.

In FIGS. 2 and 3, the disk cleaner 1 of the present invention consists of a base 2 that also serves as a grip, and six vertically long wipers 3 that wipe the surface of the disk D, and each wiper 3 is arranged in a ring shape in a vertical position. Their respective upper ends are collectively supported and fixed to the base body 2.

The base body 2 consists of a holder 4 and a cap 5, which sandwich and fix the upper end of the wiper 3 from the inside and outside. The holder 4 has a hexagonal cylindrical shape that opens downward, and has a stepped portion 6 for supporting the wiper 3 in a predetermined posture and an engagement groove 7 for preventing the wiper from coming off on its outer peripheral surface. The cap 5 which is externally fitted onto the holder 4 is also formed into a hexagonal cylinder shape, with a presser wall 8 projecting from the inner edge of the upper end of the cylinder wall, and an engaging rib 9 protruding from the lower end of the inner peripheral surface of the cylinder wall. It has been done.

The wiper 3 has a highly elastic band-like arm 11 and an arm 1.
The arm 11 has a water-absorbing cleaning pad 12 made of felt, non-woven fabric, chamois, sponge, etc. attached to the lower end of the arm 11, and the upper end of the arm 11 serves as an attachment part 13 to the base body 2. The mounting portion 13 has a structure that corresponds to the step portion 6 and the engagement groove 7 of the holder 4.
A locking piece 14 is provided protrudingly, and a retaining rib 15 having a semicircular cross section is formed. As shown in FIG. 2, the mounting portion 13 is formed to be inclined at an angle θ with respect to the plate surface of the arm 11.

The cleaning pad 12 is formed into a box shape and is externally fitted onto a retaining piece 16 provided at the lower end of the arm 11 from below. This cleaning pad 12 can be replaced as necessary.

The wipers 3 are integrated with the holder 4 by covering the cap 5 with the hooking pieces 14 of the six wipers 3 hooked onto the stepped portions 6 of the holder 4.
In this assembled state, the upper end mounting portion 13 of each wiper 3 is in close contact with the peripheral wall of the holder 4. Therefore, the arm 11 is inclined outwardly by an angle θ with respect to the vertical line. As shown in the enlarged view of FIG. 3, the retaining rib 15 of the mounting portion 13 fits into the engaging groove 7 while being sandwiched between the holder 4 and the cap 5, and at the same time the engaging rib 9 of the cap 5 prevents the retaining member from coming off. It engages with a groove on the outer surface of the rib 15. Therefore, the cap 5 has a retaining rib 15.
It is held in a manner that prevents it from coming off by the engagement groove 7 through the . The distance B between the cleaning pads 12 in the assembled state is set to be smaller than the diameter of the non-recording area 18 at the center of the disk shown in FIG. Further, the height H of the arm 11 from the disk surface was set to be slightly larger than the radial length of the disk D.

In FIG. 3, reference numeral 20 is a mounting table for a disk. This mounting table 20 has a shaft 21 at the center of the board surface, and by fitting the central hole 22 of the disk D into the shaft 21 and placing the disk D thereon, the disk D is held immovably. Recesses 23 are formed at several locations around the periphery of the surface of the mounting table 20 to facilitate removal of the disk D after cleaning.

When this is used, the front side of disk D,
In other words, place the disk D on the mounting table 20 with the side irradiated with the laser beam facing up,
is fitted onto the shaft 21. After the cleaning pads 12 of the wiper 3 are impregnated with cleaning liquid or the cleaning liquid is dropped circularly on the disk surface, each cleaning pad 12 is attached to the non-recorded area 1.
The cleaner 1 is placed on the disk D so as to surround the disk D, and the base body 2 is pressed toward the disk D.

The applied pressing force acts to buckle and deform the arm 11 of each wiper 3. Since the arm 11 is already inclined outwardly when placed on the disk surface, when it receives the pressing force, it bends and deforms into a concave shape as shown in FIG. 1, and comes into contact with the disk D. A component force is generated outward in the radial direction of the disk D on the side. This component force is the cleaning pad 12
When the frictional force with disk D is exceeded,
The cleaning pad 12 is displaced radially outward to wipe the disk surface. At this time, the wiping surface of the cleaning pad 12 moves from the lower surface side to the inner surface side, and the cleaning pad 12 slides while maintaining the state in which it is in pressure contact with the disk D.

When the cleaning pad 12 reaches the periphery of the disk D, the pressing force of the base body 2 is released and the cleaning pad 12 is separated from the disk D, and the arm 11 returns to its original standby position by its own elasticity. After this, the mounting position of the cleaner 1 is first slightly shifted from the mounting position in the circumferential direction, 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. In addition, 6
By impregnating every other wiper 3 with a cleaning liquid and performing wiping, the cleaning liquid and wiping traces adhering to the disk surface can be removed at the same time.

[Second Embodiment] FIGS. 5 and 6 show a second embodiment of the present invention. The wiper 3 in this case is composed of an arm 11 formed by bending a metal wire into a rectangular frame shape, and a roll-shaped cleaning pad 12 fixed non-rotatably to the tip of the arm 11. Arm 1 as shown in Figure 6
A shaft portion 11a at the upper end of the arm 11 is swingably connected and supported to the base body 2, and a torsion coil spring 24 attached to this connecting portion biases the entire arm 11 to a standby position. Also, in order to keep the standby posture constant, arm 1
1 is received and supported by a positioning wall 26 provided on the base body 2.

In this second embodiment, the cleaning pad 12 wipes the disk surface mainly by swinging the arm 11. Therefore, by varying the tension of the spring 24, the cleaning pad 1
The wiping pressure in step 2 can be easily changed. The spring 24 does not need to be a separate member, and can also be formed using a part of the arm 11.

[Third Embodiment] FIG. 7 shows a third embodiment of the present invention. In this case, the wiper 3 moves from the outer edge of the disk D toward the center, and the cleaner 1
This embodiment differs from the first and second embodiments in that cleaning is performed by leaving the disc D stationary and moving the disc D toward the cleaner 1.

In FIG. 7, a guide shaft 27 is provided at the center of the disk surface of the base body 2 formed in a disk shape, which fits into the center hole 22 of the disk D and guides the disk D up and down.
A wiper 3 arranged around the board surface is biased to stand up by a spring 28 so that the arm 11 is in a slightly inward posture in a standby posture. A stopper surface 29 is provided in the middle of the guide shaft 27 to define the limit for pushing down the disk D.

In this case, since the cleaning surface is always facing downward, the dust and the like that have been pushed away by the cleaning pad 12 will not re-adhere to the disk surface.

[Fourth Embodiment] FIG. 8 shows a fourth embodiment of the present invention. This has a guide shaft 27 added to the center of the holder 4 of the base body 2 described in the first embodiment.

The guide shaft 27 is supported so as to be movable relative to the holder 4, and has a stopper surface 29 at its lower part that defines the limit of downward movement of the holder 4, and a socket 30 that fits onto the shaft 21 of the mounting table 20.

By placing the cleaner 1 on the disk D with the socket 30 fitted onto the shaft 21, the cleaner 1 can always be positioned at the center of the disk. Furthermore, when pressing the base body 2 toward the disk D, the pressing force can be applied equally to each wiper 3, thereby preventing uneven wiping.

[Fifth Embodiment] FIG. 9 shows a fifth embodiment of the present invention. In this case, like the cleaner 1 described in the first embodiment, three wipers 3 having plate-shaped arms 11 are supported on the base body 2. The wiper 3 is arranged in a concentrated manner on one side of the circumferential surface of the base body 2, and an arm 31 that supports the base body 2 is connected via a swing pin 32 to the circumferential surface of the base body 2 opposite to this arrangement position. The arm 31 is supported by a bracket 33 that is movable along the periphery of the disk D so as to be able to swing up and down, and is biased to stand up by a spring built into the bracket 33.

[Another embodiment example]

The number of wipers 3 installed is not limited as long as there are two or more wipers 3, and each wiper 3 may be integrally formed in a radial shape.In this case, assembly and replacement can be performed easily.

The wiper 3 may be one that wipingly displaces in the radial direction by bending or swinging, or may be one that wipingly displaces while the entire wiper 3 moves in parallel.

The mounting table 20 is not necessarily required, and the disk D can be supported by hand for cleaning.
