Embodiment 1 FIG.
As shown in FIG. 1, the foreign matter removing tool 1 is composed of a plate-shaped member made of a flexible material, and one side is formed in an arc shape, and one side thereof is an adhesive portion 2. Further, the bent portion 3 is formed by bending the plate member so that the surface on which the adhesive portion 2 is provided is on the inside.
As the plate member made of a flexible material, polystyrene, polycarbonate, or the like may be used. The shape of the arc is substantially the same as the arc shape of CD (Compact Disc) and DVD (Digital Versatile Disc).

FIG. 2 is a side view showing an example of a conventional disk reproducing device 10, and shows the internal structure by cutting the chassis 11. An insertion port 12 for inserting and removing a disk 20 such as a CD and a DVD is formed in the chassis 11. In addition, a transport roller 13 is rotatably held inside the chassis 11, and the transport roller 13 rotates to place the disk 20 inserted from the insertion port 12 and transport it to the reproducing unit 15. At this time, the disk guide component 14 provided on the inner side of the top surface of the chassis 11 guides the disk 20 with the conveyance roller 13 therebetween. When the disk 20 is conveyed to the reproduction position, the conveyance roller 13 is moved to the lower reproduction unit 15 side by a drive mechanism (not shown), and the disk 20 is placed on the turntable 16 as indicated by a two-dot chain line in FIG. Is done.
In addition to the turntable 16 that rotates the disk 20, the reproducing unit 15 includes a clamper (not shown) that holds the disk 20 on the turntable 16, an optical pickup that performs information reproduction and information recording on the disk 20, and the like.
When the disc 20 is ejected, the conveying roller 13 is placed on the disc 20 by the driving mechanism (not shown) and moved to the upper disc guide component 14 side, and the conveying roller 13 rotates reversely to insert the disc 20 from the reproducing unit 15. It is conveyed to the mouth 12 and discharged.

As shown in FIG. 2, the disk reproducing apparatus 10 is installed with an angle θ and an insertion port 12 facing upward. Therefore, the foreign material 21 that is erroneously inserted into the chassis 11 from the insertion port 12 gathers on the back side of the chassis 11 on the surface of the reproducing unit 15. When the foreign matter 21 such as a card, a coin, a seal, and waste paper is smaller than the disk 20, it is dropped from the transport roller 13 and cannot be discharged. Further, the foreign material 21 may cause a reproduction failure and a malfunction of the disk reproducing apparatus 10.
Therefore, the foreign matter 21 is removed using the foreign matter removing tool 1. The foreign matter removing tool 1 is inserted into the insertion port 12 from the front end side where the adhesive portion 2 is provided, with the surface provided with the adhesive portion 2 facing down toward the transport roller 13 and the reproducing portion 15 side.

FIG. 3 is a view showing a state in which the foreign matter removing tool 1 is viewed from the insertion port 12 side when the disc player 10 is inserted.

The foreign substance removing tool 1 inserted from the insertion port 12 is placed on the conveyance roller 13 and conveyed to the reproducing unit 15. Since the conveying roller 13 has a tapered shape 13b that increases in diameter from the central portion of the shaft 13a toward both ends, the foreign matter removing tool 1 and the conveying roller 13 are in contact with each other at the edge. Therefore, the adhesive portion 2 is conveyed to the inside of the chassis 11 without being attached to the conveyance roller 13.
In addition, although the area for adhering the foreign material 21 is small, even if the adhesive portion 2 is made slightly smaller than the foreign material removing tool 1 and the foreign material removing tool 1 and the conveying roller 13 are brought into edge contact to prevent sticking. Good.

  4 and 5 are side views showing a state when the foreign matter removing tool 1 is inserted into the disc reproducing apparatus 10. FIG. The foreign substance removing tool 1 inserted from the insertion port 12 is conveyed along the same locus as when the normal disk 20 is inserted until the bending portion 3 reaches the conveying roller 13. Since the foreign matter removing tool 1 is nipped and conveyed from the upper surface to the disk guide component 14 and from the lower surface to the conveying roller 13, the adhesive portion 2 proceeds to the back side of the chassis 11 without contacting the reproducing portion 15.

When the bending portion 3 passes the conveying roller 13, the rear portion of the bending portion 3 is sandwiched between the conveying roller 13 and the disc guide component 14, so that the posture of the foreign matter removing tool 1 is changed, as shown by an arrow B in FIG. The front part of the bent part 3 approaches the reproducing part 15, and the adhesive part 2 at the tip is pressed against the foreign substance 21 on the surface of the reproducing part 15 to be bonded. Moreover, since the foreign material removal tool 1 bends, the contact area of the adhesion part 2 and the foreign material 21 will increase, and it will become easy to adhere | attach. It should be noted that the distance from the bending portion 3 to the adhesive portion 2 is set from the conveying roller 13 so that it does not adhere to components such as the turntable 16 and the optical pickup 22 (FIG. 6) when the posture of the foreign matter removing tool 1 changes. It is desirable that the distance is longer than the longer one of the distance to the table 16 or the distance from the transport roller 13 to the optical pickup 22. Thereby, at the position where the adhesive part 2 has passed the turntable 16 and the optical pickup 22, the bending part 3 is placed on the transport roller 13 and the posture is changed, so that the adhesive part 2 contacts the surface of the reproducing part 15. Become.
Thereafter, the conveyance roller 13 conveys the foreign material removing tool 1 and the foreign material 21 together and ejects them from the insertion port 12 by a normal disk ejection operation.

  As described above, according to the first embodiment, the foreign object removing tool 1 is inserted through the insertion port 12 of the disk reproducing device 10 and is conveyed to the reproducing unit 15 by the conveying roller 13 in the same manner as the disk 20. An adhesive portion 2 for adhering the foreign substance 21 in the chassis 11 provided on the surface of the plate-like member that is inserted into the insertion port 12 and in contact with the conveyance roller 13, and the conveyance roller. The bent portion 3 is formed by bending the plate-like member along the bend line parallel to the shaft 13a of the thirteen so that the adhesive portion 2 faces the reproducing portion 15 side. For this reason, when the bending portion 3 reaches the conveying roller 13 by the normal disc insertion operation of the disc reproducing apparatus 10, the foreign matter removing tool 1 is tilted and the adhesive portion 2 is pushed against the foreign matter 21 on the surface of the reproducing portion 15 while being bent. Can be glued. Further, the foreign matter removing tool 1 is ejected together with the foreign matter 21 by the normal disc ejecting operation of the disc reproducing device 10, so that the foreign matter can be removed from the disc reproducing device 10.

  Further, according to the first embodiment, the foreign matter removing tool 1 is configured such that the distance from the bending portion 3 to the adhesive portion 2 is the distance from the conveying roller 13 of the disk reproducing device 10 to the turntable 16 or the optical pickup 22 of the reproducing portion 15. The distance is longer than the longer one of the distances. For this reason, the adhesion part 2 can be prevented from adhering to the turntable 16 and the optical pickup 22.

Further, according to the first embodiment, since the tip end side of the foreign substance removing tool 1 is formed in the substantially same arc shape as the disk 20, the foreign substance removing tool 1 can be used regardless of the structure of the disk reproducing apparatus 10, High versatility.
