Description

  The present invention relates to a lens cleaner for cleaning an objective lens of an optical pickup.

  As this type of lens cleaner, a lens cleaner disclosed in Japanese Patent Application Laid-Open No. 2001-118276 has been conventionally known. This lens cleaner includes a disk having substantially the same shape as a compact disk, and a cleaning member implanted at a predetermined position on the disk surface of the disk. The cleaning member is, for example, a brush (cleaning brush) made of appropriate fibers, and a base end portion attached to a small hole provided in the disk is bonded and fixed with an adhesive provided at the bottom of the small hole. It is planted on the disc. In this lens cleaner, as the disk rotates, the brush rotates with a constant trajectory, thereby wiping off dirt such as foreign matter adhering to the lens surface when the tip of the brush contacts the pickup lens.

There are two types of lens cleaners of this type, dry and wet. The lens cleaner described above is a dry lens cleaner, and the wet lens cleaner applies a cleaning solution to the brush of the lens cleaner. Used.
JP 2001-118276 A (page 3-4, FIG. 1-2)

  However, the conventional wet lens cleaner has the following problems. That is, normally, in a disk device, an optical pickup is disposed below a tray on which an optical information medium such as a compact disk or a DVD is placed. For this reason, when using this lens cleaner, first, the cleaning liquid is dropped onto the brush with the surface of the disk on which the brush is implanted facing upward, and then the disk surface is turned over and the surface of the surface on which the brush is implanted is removed. Place the lens cleaner on the tray of the disk unit with the face down. However, since the power of the brush to keep the cleaning liquid is weak, this wet lens cleaner has a problem that the cleaning liquid may hang down from the brush when the disk is turned over or placed on the tray. Exists.

  The present invention has been made in view of such problems, and has as its main object to provide a lens cleaner that can prevent the cleaning liquid from dripping from the brush.

  In order to achieve the above object, the lens cleaner according to the present invention includes a disc main body, a cleaning brush implanted on one surface of the disc main body, and the cleaning device disposed on the disc main body and having water retention. And a liquid receiving member for supplying a cleaning liquid to the base of the brush.

  In this case, the liquid receiving member can be disposed with a part of the other surface of the disk body exposed.

  Further, the liquid receiving member can be disposed in a state where a part of the one surface of the disk body is exposed.

  Further, the liquid receiving member can be composed of one or more of felt, foamed plastic, nonwoven fabric and woven fabric.

  The liquid receiver includes a liquid receiver main body having water retention power and a liquid supply section having water retention power and extending from the liquid receiver main body to supply the cleaning liquid to the base of the cleaning brush. A member can also be comprised.

  Further, the cleaning brush on the one surface of the disk body is behind the cleaning brush in the rotation direction, and is closer to the outer periphery than the inner periphery of the annular region drawn by the rotated cleaning brush. A capturing brush that captures the cleaning liquid scattered from the cleaning brush can also be implanted at a position.

  According to the lens cleaner according to the present invention, the liquid receiving member having the water retaining power is disposed together with the cleaning brush on the disc body, so that the dropped cleaning liquid is kept in the liquid receiving member while being cleaned from the liquid receiving member. Cleaning liquid can be supplied to the brush little by little. Therefore, according to this lens cleaner, unlike the conventional lens cleaner in which the cleaning liquid is dripped directly onto the cleaning brush implanted in the disc body, the cleaning liquid from the cleaning brush is surely dripped downward. Can be prevented.

  In addition, according to the lens cleaner described above, since the liquid receiving member is disposed in a state where a part of the disk main body is exposed, the lens cleaner is turned over after the cleaning liquid is dropped onto the liquid receiving member. Without being attached to the disk device. Therefore, the trouble of turning the lens cleaner upside down can be saved, so that the lens cleaner can be quickly attached to the disk device. In addition, the cleaning liquid can be dropped onto the liquid receiving member in a state where the lens cleaner is placed on the tray of the disk device.

  In addition, according to the lens cleaner described above, the lens cleaner can be simply configured by disposing the liquid receiving member in a state where a part of the surface of the disk body is exposed.

  Moreover, according to said lens cleaner, a liquid receiving member can be comprised simply and cheaply by comprising a liquid receiving member in any one or more of felt, a foamed plastic, a woven fabric, and a nonwoven fabric.

  Further, according to the lens cleaner described above, the liquid receiving member includes the liquid receiving main body and the liquid supply portion that extends from the liquid receiving main body and supplies the cleaning liquid to the base of the cleaning brush. The amount of cleaning liquid supplied to the cleaning brush can be reliably prevented from dripping downward from the cleaning brush and at least one of the cross-sectional area and length of the liquid supply section can be changed. Can be controlled to an appropriate amount. Therefore, as a result of being able to reliably supply an appropriate amount of cleaning liquid from the cleaning brush with no excess or deficiency to the lens to be cleaned, the lens can be cleaned more satisfactorily.

  Further, according to the lens cleaner, the cleaning brush on the one surface of the disk main body is behind the cleaning brush in the rotation direction of the cleaning brush and is more than the inner peripheral edge of the annular region drawn by the rotated cleaning brush. Since the capture brush that captures the cleaning liquid scattered from the cleaning brush is installed at the outer peripheral position, the capture brush can prevent the cleaning liquid from spreading over a wide area. Thus, the contamination inside the disk device can be sufficiently reduced.

  Hereinafter, the best mode of a lens cleaner according to the present invention will be described with reference to the drawings.

  First, the configuration of the lens cleaner 1 will be described with reference to the drawings.

  As shown in FIGS. 1 and 2, the lens cleaner 1 includes a disc main body 2, a liquid receiving member 3, and a cleaning brush 4. In this case, the disc main body 2 is, for example, the same as a disc-shaped information medium mounted on a disc reproducing device or disc recording / reproducing device having an optical pickup to be cleaned (hereinafter also referred to as “disk device” unless otherwise specified). The outer shape is formed. Further, as shown in FIG. 4, the disc body 2 has a mounting recess 5 formed on the other surface 2b, and from the bottom surface 5a of the mounting recess 5 to one surface (opposite surface to the optical pickup) 2a. The through-hole 6 reaching to is formed. The mounting recess 5 is configured to have a planar shape and depth to which the liquid receiving member 3 can be mounted, and the through-hole 6 has a cross-sectional shape along a plane parallel to the one surface 2a into which the cleaning brush 4 can be inserted. It is configured in a shape (for example, a circle).

  The liquid receiving member 3 is made of at least one of felt, foamed plastic, nonwoven fabric, and woven fabric. In this case, porous materials such as felt, foamed plastic (for example, sponge) and non-woven fabric have excellent water retention (or water absorption), and woven fabric also has water absorption. For this reason, the liquid receiving member 3 is configured to be able to supply the cleaning liquid to the cleaning brush 4 while impregnating (absorbing water) the dropped cleaning liquid (alcohol, purified water, or a mixture of both). Further, as shown in FIG. 3, the liquid receiving member 3 is formed into a disc body (diameter is about 0.7 cm) as shown in FIG. 3, and its thickness is substantially the same as the depth of the mounting recess 5 (as an example, 0.4 mm). ) Is set. With this configuration, the liquid receiving member 3 can keep one dropped cleaning liquid from overflowing from the mounting recess 5. Further, as shown in FIG. 4, the liquid receiving member 3 is formed to have a larger planar shape than the cleaning brush 4, and is mounted at a position eccentric from the center of one surface (the lower surface in the figure) 3a. 3b is formed. As shown in FIGS. 3 and 4, the cleaning brush 4 is configured by bundling ultra-fine brush bristles in a cylindrical shape and, as shown in FIG. 4, the base 4a is mounted in the mounting hole 3b. In addition, the intermediate portion 4b and the tip portion 4c are integrated (planted) into the liquid receiving member 3 in a state of projecting from the one surface 3a of the liquid receiving member 3 substantially at right angles. As an example, the cleaning brush 4 is fixed to the liquid receiving member 3 by adhering the end surface on the base portion 4a side to the bottom surface of the mounting hole 3b with the adhesive 7.

  Further, the liquid receiving member 3 and the cleaning brush 4 integrated with each other as described above are for cleaning in a state where the adhesive 8 is applied to one surface 3a of the liquid receiving member 3, as shown in FIG. By inserting the brush 4 into the through hole 6, the brush 4 is mounted inside the mounting recess 5 and the through hole 6. Therefore, as shown in FIGS. 2 and 5, the liquid receiving member 3 has one surface 3 a bonded to the bottom surface 5 a of the mounting recess 5 by the adhesive 8, and the other surface 3 c is entirely in the other side of the disc body 2. It is attached to the disc main body 2 in a state of being exposed on the surface 2b (an example in which at least a part is exposed on the other surface of the disc main body in the present invention). Not limited to this configuration, a part of the other surface 3c, which is defined as wide enough to allow the cleaning liquid 10 described later to be dropped, is exposed to the other surface 2b of the disc body 2 in the disc body 2. It can also be attached. In the cleaning brush 4, the tip portion 4 c penetrates the through hole 6 and protrudes from the one surface 2 a of the disc body 2 at a substantially right angle, and the intermediate portion 4 b is supported by the wall surface of the through hole 6. It is attached to the disc body 2 (planted).

  Next, a method for using the lens cleaner 1 will be described.

  First, as shown in FIGS. 2 and 5, the disk main body 2 is arranged with one surface 2 a facing downward, and one drop of the cleaning liquid 10 is dropped from the cleaning liquid bottle 9 onto the other surface 3 c of the liquid receiving member 3. To do. At this time, since the cleaning brush 4 is not implanted on the other surface 3 c of the liquid receiving member 3, the cleaning liquid 10 is dropped onto the liquid receiving member 3 without being obstructed by the cleaning brush 4. Can do. In this case, the dropped cleaning liquid 10 spreads over the entire liquid receiving member 3, and is transmitted along the base 4 a of the cleaning brush 4 implanted in the liquid receiving member 3 and the intermediate portion 4 b and the tip of the cleaning brush 4. Supplied to the unit 4c. Thereby, the cleaning liquid 10 is held by both the liquid receiving member 3 and the cleaning brush 4. Next, the lens cleaner 1 is mounted on the disk device. In the lens cleaner 1, the liquid receiving member 3 is exposed on the back surface (the other surface 2 b) of the surface (the one surface 2 a) on which the cleaning brush 4 is implanted in the disc body 2 as described above. It is installed. Therefore, the lens cleaner 1 can be first placed on the tray of the disk device, and then the cleaning liquid 10 can be dropped onto the liquid receiving member 3.

  Subsequently, the reproducing operation is started for the disk device. During the reproducing operation, the disk device rotates the lens cleaner 1 and moves the optical pickup along the radial direction of the lens cleaner 1, for example, from the inner peripheral side toward the outer peripheral side. Therefore, when the optical pickup passes through the rotation region of the cleaning brush 4, the tip 4c of the cleaning brush 4 contacts the lens of the optical pickup, and at that time, the lens is cleaned cleanly. In this case, when the tip portion 4c is in contact with the lens of the optical pickup, the cleaning brush 4 is subjected to stress in the direction opposite to the rotation direction of the lens cleaner 1 from the optical pickup, but the intermediate portion 4b penetrates. Since it is supported by the wall surface of the hole 6, a large inclination of the cleaning brush 4 is avoided. Therefore, in this lens cleaner 1, the tip 4c of the cleaning brush 4 can be kept in contact with the lens of the optical pickup at a substantially right angle, so that dust and dirt attached to the lens by the cleaning brush 4 can be prevented. It is wiped off reliably.

  As described above, according to the lens cleaner 1, the liquid receiving member 3 having the water retaining power is disposed together with the cleaning brush 4 on the disc body 2, so that the dropped cleaning liquid 10 is kept in the liquid receiving member 3. The cleaning liquid 10 can be supplied little by little from the liquid receiving member 3 to the cleaning brush 4. Therefore, according to the lens cleaner 1, unlike the conventional lens cleaner in which the cleaning liquid is directly dropped onto the cleaning brush implanted in the disc body, the cleaning liquid 10 hangs down from the cleaning brush 4. Can be reliably prevented. Further, according to the lens cleaner 1, since the cleaning liquid 10 is dropped on the liquid receiving member 3 having a larger planar shape than the cleaning brush 4, the disk main body is compared with the structure of dropping directly on the cleaning brush. The cleaning liquid 10 can be dropped while reliably avoiding erroneous dripping of the cleaning liquid 10 onto the surface of No. 2. Accordingly, it is possible to avoid the cleaning liquid 10 from adhering to the surface of the disc main body 2, so that the cleaning liquid 10 adhering to the surface of the disc main body 2 is surely scattered into the disc device when the lens cleaner 1 rotates. Can be prevented.

  Further, according to the lens cleaner 1, the liquid receiving member 3 is disposed in a state where the liquid receiving member 3 is exposed on the other surface 2b which is the back surface of the one surface 2a from which the cleaning brush 4 in the disk main body 2 protrudes. After the cleaning liquid 10 is dropped on the liquid receiving member 3, the lens cleaner 1 can be mounted on the disk device without turning it over. Therefore, the trouble of turning the lens cleaner 1 upside down can be saved. As a result, the lens cleaner 1 can be quickly attached to the disk device. Further, the cleaning liquid 10 can be dropped onto the liquid receiving member 3 in a state where the lens cleaner 1 is placed on the tray of the disk device.

  In addition, this invention is not limited to said structure. For example, in the above configuration, as shown in FIG. 3, the cleaning brush 4 is implanted at a position eccentric from the center of the liquid receiving member 3, but as shown in FIG. It is also possible to employ a configuration in which the mounting hole 3 b is provided in the part and the cleaning brush 4 is implanted in the center of the liquid receiving member 3. Although not shown, a configuration in which a plurality of cleaning brushes 4 are implanted in the liquid receiving member 3 may be employed. Further, in the above-described configuration, the cleaning brush 4 is formed by bundling ultra-fine brush bristles in a columnar shape, but the ultra-fine brush bristles are implanted linearly (rectangular shape) on the surface of the liquid receiving member 3. A configuration can also be adopted.

  In the above configuration, the cleaning brush 4 is bonded to the liquid receiving member 3 with the adhesive 7, and the liquid receiving member 3 is bonded to the disc body 2 with the adhesive 8, so that the liquid receiving member 3 is interposed therebetween. Although the cleaning brush 4 is attached to the disc main body 2, a configuration in which the cleaning brush 4 is directly bonded to the disc main body 2 may be employed. As an example, a disk-shaped liquid receiving member 13 is shown in FIG. In the liquid receiving member 13, a recess 13 b is formed on the side wall instead of the mounting hole 3 b of the liquid receiving member 3, and the base 4 a of the cleaning brush 4 is mounted in the recess 13 b. Further, when the liquid receiving member 13 is attached to the disc body 2, the adhesive 8 is disposed on one surface 13a of the liquid receiving member 13 and the adhesive 8A is disposed on the side surface of the base 4a. The combined liquid receiving member 13 and cleaning brush 4 are mounted in the mounting recess 5 and the through hole 6 of the disc body 2. According to this configuration, the liquid receiving member 13 is bonded to the bottom surface 5a of the mounting recess 5 by the adhesive 8, and the cleaning brush 4 is bonded to the inner peripheral surface of the mounting recess 5 by the adhesive 8A. The disc body 2 is directly bonded.

  Further, in the above configuration, the liquid receiving member 3 is disposed on the disc main body 2 so as to be exposed on the other surface 2b of the disc main body 2 (a surface not facing the optical pickup), and one side of the disc main body 2 is disposed. Although the cleaning brush 4 protrudes from 2a, it can also be configured like a lens cleaner 21 shown in FIGS. The lens cleaner 21 includes a disk body 22 having a mounting recess 5 formed on one surface 22a (a surface facing the optical pickup), and a liquid receiving member 3 in which a cleaning brush 4 is implanted as shown in FIG. On the other hand, as shown in FIG. 8, the adhesive 8 is disposed on the other surface 3c, and the liquid receiving member 3 is mounted on the mounting recess 5 from the other surface 3c side and adhered to the bottom surface 5a. The liquid receiving member 3 and the cleaning brush 4 are attached to the disc main body 22. That is, the lens cleaner 21 employs a simple configuration in which the liquid receiving member 3 is not exposed on the other surface 22b of the disc main body 22. In addition, about the structure same as the lens cleaner 1, the same code | symbol is attached | subjected and the overlapping description is abbreviate | omitted. In this lens cleaner 21, as shown in FIG. 9, one drop of the cleaning liquid 10 is dropped from the bottle 9 onto the liquid receiving member 3 in a state where the disk main body 22 is disposed with one surface 22a facing upward, and then the disk After the main body 22 is turned over so that one surface 22a faces downward, the lens cleaner 21 is attached to the disk device. Also in the lens cleaner 21 configured in this way, in the same manner as the lens cleaner 1, while the dropped cleaning liquid 10 is maintained by the liquid receiving member 3 having an excellent water holding power, the cleaning brush 4 is removed from the liquid receiving member 3. The cleaning liquid 10 can be supplied little by little. Therefore, this lens cleaner 21 can also reliably prevent the cleaning liquid 10 from dripping down from the cleaning brush 4.

  Further, in the above configuration, the liquid receiving members 3 and 13 are formed in a disc body as an example, but the shape of the liquid receiving member is not limited to a disc body (a cylindrical shape having a circular planar shape), and a planar shape. Can be configured in various shapes such as an elliptic cylinder, a triangular prism, a polygonal prism such as a quadrangle, or a combination of these. For example, like a liquid receiving member 33 of the lens cleaner 31 shown in FIG. In addition, about the structure same as the lens cleaner 1, the same code | symbol is attached | subjected and the overlapping description is abbreviate | omitted.

  The liquid receiving member 33 includes a liquid receiving main body 34 formed in a disc body and a rectangular parallelepiped, and extends from the side of the liquid receiving main body 34 so as to be applied to the base 4a of the cleaning brush 4 to the cleaning liquid 10. And a liquid supply unit 35 for supplying the liquid. In this case, the liquid receiver main body 34 and the liquid supply part 35 are both formed integrally and to the same thickness by resin molding using a material having a water retention capacity in the same manner as the liquid receiver 3. . Further, the cleaning brush 4 is implanted by bonding in a state substantially perpendicular to one surface (the lower surface in FIG. 10) of the liquid supply portion 35, similarly to the liquid receiving member 3. On the other hand, on the other surface 32b of the disk main body 32 to which the liquid receiving member 33 is attached, a mounting concave portion 36 for mounting the liquid receiving main body portion 34, and a mounting concave portion 37 for mounting the liquid supply portion 35, Are formed in communication with each other. In addition, a through hole 6 for the cleaning brush 4 reaching the bottom surface of the mounting recess 37 is formed on one surface (a surface facing the optical pickup) 32 a of the disc body 32. In the lens cleaner 31 including the liquid receiving member 33 and the disk main body 32 having the above-described configuration, the liquid receiving main body 34 is mounted in the mounting recess 36, the liquid supply unit 35 is mounted in the mounting recess 37, and the cleaning is performed. The brush 4 is inserted into the through hole 6 so that the tip end 4c protrudes from the one surface 32a.

  When using the lens cleaner 31, first, the cleaning liquid 10 is dropped onto the liquid receiving main body 34. At this time, the dropped cleaning liquid 10 spreads over the entire liquid receiving main body 34, then reaches the liquid supply section 35, and further travels through the base 4 a of the cleaning brush 4 installed in the liquid supply section 35. It is supplied to the tip 4c of the cleaning brush 4. In this case, the supply amount of the cleaning liquid 10 to the cleaning brush 4 is adjusted by changing at least one of the cross-sectional area (cross-sectional area in the direction orthogonal to the length direction) and the length of the liquid supply unit 35. For example, in the liquid receiving member 33 shown in FIG. 11, the supply amount to the cleaning brush 4 is reduced by reducing the thickness of the liquid supply part 35 and reducing the cross-sectional area thereof. In the liquid receiving member 33 shown in the figure, the cleaning brush 4 is inserted into the through hole 6 so that the tip end portion 4c protrudes from the one surface 32a.

  According to this lens cleaner 31, the liquid receiving member 33 including the liquid receiving main body 34 and the liquid supply section 35 is attached to the disk main body 32, so that the cleaning liquid 10 is dripped downward from the cleaning brush 4. Can be reliably prevented, and the supply amount of the cleaning liquid 10 to the cleaning brush 4 can be controlled to an appropriate amount by changing at least one of the cross-sectional area and the length of the liquid supply portion 35. Therefore, as a result of being able to reliably supply an appropriate amount of the cleaning liquid 10 from the cleaning brush 4 without excess or deficiency to the lens of the optical pickup, the lens can be cleaned more satisfactorily.

  In the lens cleaner 31, the liquid receiving member 33 is mounted on the disc main body 32 so that the surface of the liquid supply unit 35 on which the cleaning brush 4 is implanted is inserted into the mounting recess 37. However, it is not limited to this. For example, the mounting recess 36 and the mounting recess 37 are formed on the one surface 32 a side of the disc main body 32, and the back side of the surface on which the cleaning brush 4 is implanted in the liquid supply unit 35 is placed in the mounting recess 37. The liquid receiving member 33 can also be attached to the disc body 32 by being inserted into the disc body 32. In this case, the formation of the through hole 6 is not necessary. Similarly, in the liquid receiving member 33 in which the thickness of the liquid supply portion 35 is thinner than the thickness of the liquid receiving main body portion 34 as shown in FIG. 11, the liquid receiving member 33 is similarly attached to one surface of the disk main body 32. It can also be mounted on the 32a side. Further, as shown in FIG. 12, the cleaning brush 4 is implanted on the surface (the lower surface in the drawing) flush with the surface of the liquid receiving body 34 in the liquid supply unit 35, and cleaning in the liquid supply unit 35 is performed. By mounting the liquid receiving main body 34 and the liquid supply section 35 on the mounting recesses 36 and 37 formed on the one surface 32a side of the disk main body 32 from the back side of the surface on which the brush 4 is implanted, the liquid The receiving member 33 is attached to the one surface 32 a side of the disc main body 32.

  Further, in the lens cleaner provided with this type of wet cleaning brush, when the tip portion 4c of the cleaning brush 4 moves away from the lens of the optical pickup, a part of the cleaning liquid 10 supplied to the tip portion 4c is removed. Scatter. In this case, as shown in FIG. 13, when the direction of the arrow W is the rotation direction of the lens cleaner, the cleaning liquid 10 is rotated on the rear side of the cleaning brush 4 in the rotation direction of the cleaning brush 4. It mainly scatters to the outer peripheral side from the inner peripheral edge X1 of the annular region X drawn by the cleaning brush 4. Specifically, a region sandwiched between a line segment Y1 connecting the rotation center O of the lens cleaner and the cleaning brush 4 and a tangent line Y2 to the inner peripheral edge X1 at the intersection of the line segment Y1 and the inner peripheral edge X1 (in FIG. 13). The cleaning liquid 10 scatters in the hatched area Z in FIG. Therefore, as in the lens cleaner 41 shown in the figure, the capturing brush 42 is taken as an example at a position in the region Z that is on the outer peripheral side of the annular region X and slightly separated from the cleaning brush 4. By planting in an arc shape, the cleaning liquid 10 scattered from the cleaning brush 4 is captured by the capturing brush 42.

  According to the lens cleaner 41, the cleaning liquid 10 can be prevented from scattering over a wide range by the capturing brush 42, so that the contamination inside the disk device due to the scattered cleaning liquid 10 can be sufficiently reduced. Since the lens cleaner 41 is configured by adding the capturing brush 42 to the lens cleaner 1, the same components as those of the lens cleaner 1 are denoted by the same reference numerals and redundant description is omitted. Further, in this lens cleaner 41, as an example, a plurality (three in this example) of cleaning brushes 4 are linearly planted along the radial direction, but the number of cleaning brushes 4 is one. Also in the cleaners 1, 21, 31, the scattering of the cleaning liquid 10 can be sufficiently reduced by disposing the capturing brush 42. Further, the capturing brush 42 can be planted in a straight line or a broken line instead of an arc. Further, by defining the protruding length of the capturing brush 42 to be longer than that of the cleaning brush 4, scattering of the cleaning liquid 10 can be further reduced.

  Further, in the above configuration, the cleaning brush 4 is planted on the liquid receiving members 3 and 33 by bonding. However, the cleaning brush 4 can be planted by press-fitting instead of the bonding, and the cleaning brush 4 can be mounted on the base 4a of the cleaning brush 4. A drop prevention mechanism (for example, a flange portion on the outer peripheral surface of the base portion 4a) may be provided so that the liquid receiving members 3 and 33 can be implanted so as not to be removed.

  Further, in the above configuration, the cleaning brush 4 is implanted in the disc main body 2 in a linearly stretched state as shown in FIG. 4, for example, like a lens cleaner 51 shown in FIG. The base portion 4a can be implanted in the disc body 2 in a state where the base portion 4a is bent at a substantially right angle with respect to the intermediate portion 4b and the tip portion 4c. In this case, as shown in FIG. 14, the cleaning brush 4 has the base portion 4 a bent at approximately 90 degrees with respect to the intermediate portion 4 b and the tip portion 4 c, and the base portion 4 a is formed on one surface 3 a of the liquid receiving member 3. Arranged along the central portion. Further, the cleaning brush 4 is disposed on the liquid receiving member 3 so that the intermediate portion 4 b and the tip portion 4 c stand substantially perpendicular to the one surface 3 a of the liquid receiving member 3. Further, when the cleaning brush 4 is attached, the adhesive 8 is applied to the entire one surface 3a of the liquid receiving member 3 or the peripheral portion of the one surface 3a around the portion where the cleaning brush 4 is disposed. Next, the liquid receiving member 3 is mounted in the mounting recess 5 such that the intermediate portion 4 b and the tip portion 4 c of the cleaning brush 4 are inserted into the through hole 6 of the disc body 2. As a result, as shown in FIG. 15, the liquid receiving member 3 has one surface 3 a bonded to the bottom surface 5 a of the mounting recess 5 by the adhesive 8, and the other surface 3 c is entirely in the other side of the disc body 2. It is attached to the disc main body 2 while being exposed on the surface 2b. In this state, since the base 4a is sandwiched between the one surface 3a of the liquid receiving member 3 and the bottom surface 5a of the mounting recess 5, the cleaning brush 4 is implanted in the disc body 2 in a state in which it cannot be removed. Is done. In addition, it can replace with the adhesive agent 8 and can also use a double-sided tape. The lens cleaner 51 configured as described above is used by dropping the cleaning liquid 10 onto the other surface 3 c of the liquid receiving member 3 in the same manner as the lens cleaner 1.
