The take-up reel 31 is a reel that takes up and collects the used cleaning body.
The gear 31 a is a gear having a plurality of teeth formed around a disc-shaped substrate, and is mounted on the take-up reel 31. A transmission mechanism (not shown) is disposed between the gear 31a and the take-up reel 31, and when the gear 31a rotates in a predetermined direction, the take-up reel 31 rotates together, but the gear 31a rotates in the reverse direction. When taking up, the take-up reel 31 is configured not to rotate.
The support portion 32 rotatably supports the supply reel 30 and the take-up reel 31. The support portion 32 is provided so as to be relatively movable with respect to the case body 11 in the front-rear direction (corresponding to a predetermined direction).
The holding cylinder portion 33 is a member that mounts the coil spring 34 and positions the coil spring 34. The holding cylinder portion 33 is provided so as to protrude rearward from the front end portion of the support portion 32.
The coil spring 34 is provided between the holding cylinder portion 33 of the support portion 32 and the pressing plate 58 of the case body 11, and the support portion 32 is rearward (in the direction of the arrow in FIG. 2) with respect to the case body 11. When moved, the support portion 32 is urged forward with respect to the case body 11.

The rotation mechanism 15 is for rotating the head member 24. The rotation mechanism 15 includes a rotation shaft 52 that can rotate with respect to the case body 11.
The rotating shaft 52 includes a guide tube portion 521 and a rotating tube portion 522. Further, an insertion hole (not shown) through which the cleaning body is inserted is formed in the rotary shaft 52. The insertion hole has a substantially circular cross section, and is formed from the front end of the guide tube portion 521 to the rear end of the rotating tube portion 522.
The guide tube portion 521 is formed in a substantially cylindrical shape, and the base portion 25 of the head member 24 can be fitted to the front end portion. On the inner surface of the front end portion of the guide tube portion 521, a thick rotation stop portion (not shown) is formed.
The rotating cylinder part 522 is provided at the rear end of the guide cylinder part 521 and is formed in a substantially cylindrical shape that is thicker than the guide cylinder part 521. Further, a cam groove 523 into which the insertion convex portion 54 of the case body 11 is inserted is formed on the outer surface of the rotary cylinder portion 522.
The cam groove 523 is formed in a spiral shape on the outer peripheral surface of the rotating cylinder portion 522 so as to be inclined with respect to the axial direction (front-rear direction) of the rotating cylinder portion 522. For this reason, when the rotating shaft 52 moves in the front-rear direction, the rotating cylindrical portion 522 moves along the cam groove 523, so that the rotating shaft 52 is rotated around the axis about the front-rear direction (hereinafter, also referred to as a rotating direction). Rotate to. Along with this rotation, the head member 24 also rotates in the same direction.

  The insertion portion 20 is a portion that is inserted into an insertion port of a cleaning target (optical connector), and is provided so as to protrude forward from the tool body 10. Further, the insertion portion 20 is movable in the front-rear direction (corresponding to a predetermined direction) with respect to the tool body 10. The insertion portion 20 of this embodiment includes an insertion cylinder 21, a cylinder spring 22, a head spring 23, and a head member 24.

  The insertion cylinder 21 has a base cylinder part 21a and a cylindrical tip cylinder part 21b extending forward from the tip (front end) of the base cylinder part 21a. The base cylinder part 21 a is fixed to the support part 32. The distal end cylinder part 21b is formed thinner than the base cylinder part 21a, and is formed so as to be positioned when inserted into the insertion port of the optical connector.

  The cylinder portion spring 22 is for urging the front end cylinder portion 21b to the front side so as to be retractable relative to the support portion 32, and is arranged between the rear end of the front end cylinder portion 21b and the support portion 32. Yes. Note that the front end cylinder part 21b receives a forward force from the spring 22 for the cylinder part. However, the protrusion part 211 of the front end cylinder part 21b contacts the inner wall of the base cylinder part 21a, so that the front end cylinder part 21b becomes the base. The cylinder portion 21a is prevented from falling off to the front side.

  The head spring 23 is for urging the head member 24 forward with respect to the guide tube portion 521 so that the head member 24 can be retracted, and between the front end of the guide tube portion 521 and the flange portion 26 of the head member 24. Is provided.

  The head member 24 is a part that presses the cleaning body against the surface to be cleaned by a pressing surface 27a described later. The head member 24 is pressed forward by the head spring 23 so as to be retractable. The head member 24 is a resin member and has a base portion 25, a flange portion 26, and a distal end portion 27.

  The base portion 25 is provided so as to be inserted into the insertion hole of the guide tube portion 521. Further, the base portion 25 has a flat portion (not shown) formed along the front-rear direction, and the flat portion and the rotation stop portion of the guide tube portion 521 are arranged to face each other. As a result, the base 25 is regulated so as not to rotate with respect to the guide tube portion 521 (rotating shaft 52). In other words, the head member 24 can move relative to the rotating shaft 52 in the front-rear direction, and rotates in the same direction together with the rotating shaft 52 in response to a rotating force around the rotating shaft 52 (force in the rotating direction). .

  The flange portion 26 is formed at the front end of the base portion 25. A head spring 23 is provided between the rear end of the flange portion 26 and the front end of the guide tube portion 521.

  The tip portion 27 is formed so as to protrude forward from the front end surface of the flange portion 26. And the cleaning body is wound around the front side end surface (pressing surface 27a) of the front-end | tip part 27 (refer FIG. 4B). The detailed configuration of the distal end portion 27 will be described later.

  The cleaning body is supplied from the supply reel 30 to the pressing surface 27a of the head member 24, and is disposed so as to be wound around the take-up reel 31 via the pressing surface 27a (detailed arrangement will be described later). The cleaning body is not particularly limited, and a known appropriate cleaning cloth (nonwoven fabric or woven fabric) processed into a thread shape can be employed. For example, what was comprised by ultra fine fibers, such as polyester and nylon, can be illustrated. In addition, a narrow tape-shaped thing can also be used as a cleaning body.

<< Operation of Cleaning Tool 1 >>
When the distal end cylindrical portion 21b of the insertion portion 20 is inserted into a connector insertion opening (not shown) of the optical connector, the head member 24 enters the insertion opening while the outer surface of the distal end cylindrical portion 21b is positioned on the inner wall of the optical connector, and the head The cleaning body on the pressing surface 27a of the member 24 contacts the surface to be cleaned (see FIG. 5A).

  When the tool body 10 is further pressed forward with the cleaning body in contact with the surface to be cleaned, the tool body 10 moves in this direction (forward). Thereby, the front-end | tip of the insertion part 20 is pushed by cleaning object, and the relative position of the insertion part 20 with respect to the tool main body 10 moves back (the tool main body 10 and the insertion part 20 move relatively).

  At this time, the support portion 32 is pushed by the insertion portion 20 and moves rearward with respect to the case body 11. Thereby, since the feed mechanism 13 moves with respect to the case body 11 together with the support portion 32, a rotational force is given to the gear 31 a by the gear receiving portion 56. The take-up reel 31 is rotated by the rotation of the gear 31a, and the cleaning body is taken up (collected). Along with this, the cleaning body is pulled out from the supply reel 30 and supplied to the pressing surface 27 a of the head member 24. In this way, the cleaning body is supplied and collected.

  Further, the rotation shaft 52 moves backward with respect to the case body 11 by the movement of the insertion portion 20. Thereby, the rotating cylinder part 522 moves along the cam groove 523, and the rotating shaft 52 rotates around the axis (rotating direction) about the front-rear direction. Since the head member 24 is also rotated by the rotation of the rotary shaft 52, the cleaning body rotates in the rotation direction while being in contact with the surface to be cleaned.

  When the tool body 10 and the insertion portion 20 are moved relative to each other in this way, the cleaning body is supplied and recovered, and the head member 24 rotates about an axis about the front-rear direction (rotation direction). As a result, dirt such as dust, dust and oil adhering to the surface to be cleaned can be wiped off with the cleaning body hung around the pressing surface 27a of the head member 24.

  When the insertion portion 20 is pulled out from the optical connector after the cleaning is completed, the tool body 10 may be moved backward. At this time, the positional relationship between the support portion 32 and the case body 11 is restored to the original by the elastic force of the coil spring 34. Thereby, the rotating shaft 52 (head member 24) rotates in the direction opposite to the direction of pressing. However, when pulling out, since the rotation of the gear 31a is not transmitted to the take-up reel 31 by a transmission mechanism (not shown), the take-up reel 31 does not rotate and only the gear 31a rotates.

<< Regarding the Configuration of the Tip 27 of the Head Member 24 >>
4A and 4B are enlarged perspective views of the distal end portion 27 of the head member 24 of the present embodiment. FIG. 4A is a diagram illustrating a state where the cleaning body is not disposed, and FIG. 4B is a diagram illustrating a state where the cleaning body is disposed. FIG. 5A is a cross-sectional view showing a state in which the distal end portion 27 of this embodiment is abutted against a cleaning target, and FIG. 5B is a cross-sectional view showing a state in which the front end portion 127 of a comparative example is abutted against the cleaning target. is there. 5A and 5B show a ferrule 100 that holds an end portion of the optical fiber 110 as an example of an object to be cleaned. The ferrule end face 100a at the end of the ferrule 100 is a connection end face with the ferrule of the counterpart optical connector. The ferrule end surface 100a is substantially circular, and a tapered surface 100b is formed on the outer side thereof. Further, the ferrule 100 is formed with an optical fiber hole 100c for positioning the optical fiber 110 along the front-rear direction, and the optical fiber 110 is inserted into the optical fiber hole 100c. And the end surface of the optical fiber 110 is arrange | positioned at the ferrule end surface 100a.

<Comparative example>
Before describing this embodiment, a comparative example will be described first.

  5B, a supply side insertion hole 127c and a collection side insertion hole 127d are formed on a pressing surface 127a for pressing the cleaning body against the ferrule end surface 100a. Then, the cleaning body passes through the supply side guide groove 127e and the supply side insertion hole 127c of the distal end portion 127, reaches the pressing surface 127a, and is recovered through the recovery side insertion hole 127d and the recovery side guide groove 127f. As described above, in the comparative example, the cleaning body is inserted into the supply side insertion hole 127c and the recovery side insertion hole 127d formed in the pressing surface 127a of the distal end portion 127, thereby preventing the cleaning body from falling off. In addition, on the supply side and the recovery side, the cleaning body is not easily moved out of the guide groove by setting the moving path (passage) of the cleaning body to the inner side (axial center side).

  However, in the case of this comparative example, since the opening of the supply side insertion hole 127c and the collection side insertion hole 127d is formed in the pressing surface 127a, the outer periphery of each of these insertion holes (the part indicated by reference numeral 127g in FIG. 5B). The area | region which arrange | positions the cleaning body of the press surface 127a becomes narrow by the thickness. That is, the length of the cleaning body hung around the pressing surface 127a is shortened, and the cleaning range is narrowed. Further, when the front end portion 127 is pressed against the ferrule 100, the pressing surface 127a may be displaced with respect to the ferrule end surface 100a, which may cause a cleaning failure.

<This embodiment>
As shown in FIGS. 4A, 4B, and 5A, the distal end portion 27 of the head member 24 of the present embodiment includes a pressing surface 27a, a protruding portion 27b, a supply side insertion hole 27c, a collection side insertion hole 27d, and a supply side. A guide groove 27e and a collection-side guide groove 27f are provided. The cleaning body passes from the supply reel 30 through the insertion hole in the rotary shaft 52, the supply side guide groove 27e, the supply side insertion hole 27c, the pressing surface 27a, and the recovery side insertion hole 27d of the distal end portion 27 of the head member 24. The winding reel 31 is disposed so as to be wound through the collection guide groove 27f. In this way, the cleaning body is wound around the pressing surface 26a.

  The pressing surface 27a is a front end surface of the distal end portion 27, and is a surface for pressing the cleaning body against the surface to be cleaned (ferrule end surface 100a). The pressing surface 27a of the present embodiment is substantially circular corresponding to the ferrule end surface 100a.

  The protruding portion 27b protrudes forward of the pressing surface 27a (that is, the ferrule 100 side) outside the pressing surface 27a. As shown in FIGS. 4A and 4B, the protruding portion 27b is provided in an annular shape surrounding the pressing surface 27a. Further, as shown in FIG. 5A, the inside of the protruding portion 27 b has a tapered shape corresponding to the inclination of the tapered surface 100 b of the ferrule 100. The protruding amount of the protruding portion 27b from the pressing surface 27a is set to be larger than the diameter (diameter) of the cleaning body. For this reason, when the front-end | tip part 27 is pressed on the ferrule 100, the protrusion part 27b contacts the taper surface 100b of the ferrule 100, and guides the head member 24. FIG. Thereby, alignment with respect to the ferrule 100 is performed, and position shift of the ferrule end surface 100a and the pressing surface 27a can be suppressed.

  In addition, although the taper surface 100b is formed in the ferrule 100 of this embodiment, the taper surface 100b does not need to be formed. Alternatively, the protrusion 27 b may not have a shape (taper shape) corresponding to the tapered surface 100 b of the ferrule 100. Even in these cases, if the protruding portion 27b is formed so as to be fitted to the outer peripheral surface of the cylindrical portion of the ferrule 100 (the portion indicated by reference numeral 100d in FIG. 5A), when the tip portion 27 is pressed against the ferrule 100, The protruding portion 27 b can contact the outer peripheral surface of the cylindrical portion of the ferrule 100 to guide the head member 24. Thereby, alignment with respect to the ferrule 100 can be performed. However, if the protrusion 27b has a shape that fits the tapered surface 100b of the ferrule 100, it can be said that the outer diameter of the tip 27 can be made thinner than the shape that fits the outer peripheral surface of the cylindrical portion of the ferrule 100. There are advantages.

  The supply-side guide groove 27e is a groove for guiding the feeding movement at the time of supply to the pressing surface 27a of the cleaning body, and along the front-rear direction at the side portion of the tip portion 27 (the upper side portion in FIG. 5A). Is formed. The collection-side guide groove 27f is a groove for guiding the feed movement at the time of collection from the pressing surface 27a of the cleaning body, and the side portion of the tip end portion 27 opposite to the supply-side guide groove 27e (the lower side in FIG. 5A). Side side) is formed along the front-rear direction. Further, as shown in FIG. 5A, the supply-side guide groove 27e and the collection-side guide groove 27f of the present embodiment are shallower as they approach the pressing surface 27a. That is, the supply-side guide groove 27e and the collection-side guide groove 27f are formed in a tapered shape that is inclined with respect to the front-rear direction. Thereby, on the front side, the position of the insertion hole (supply side insertion hole 27c and recovery side insertion hole 27d) can be formed at a position away from the center of the pressing surface 27a (in this embodiment, the protruding portion 27b). The length of the cleaning body hung around the pressing surface 27a can be increased. That is, the area of the pressing surface 27a can be expanded. Further, since the depth of each guide groove is large on the rear side, the cleaning body is difficult to come out to the outside.

  The supply side insertion hole 27c is a hole through which the cleaning body is inserted from the supply side guide groove 27e into the pressing surface 27a. The collection side insertion hole 27d is a hole through which the cleaning body is inserted from the pressing surface 27a into the collection side guide groove 27f. The supply side insertion hole 27c and the recovery side insertion hole 27d of the present embodiment are provided in the protruding portion 27b. More specifically, the supply-side insertion hole 27c and the collection-side insertion hole 27d are provided at positions facing each other across the pressing surface 27a in the annular protrusion 27b. Thereby, in this embodiment, the length of the cleaning body hung around the pressing surface 27a can be made longer than in the comparative example, and the pressing surface can be expanded (cleaning range can be expanded) (FIG. 5A, (See FIG. 5B). Further, in the present embodiment, the supply side insertion hole 27c and the recovery side insertion hole 27d are formed in the protruding portion 27b, so that the outside of the cleaning body is surrounded by the protruding portion 27b. Therefore, the cleaning body can be prevented from falling off. In addition, since the thickness of the outer periphery (part shown by the code | symbol 27g of FIG. 4A) of the insertion hole is located in the protrusion part 27, it can prevent dropping of the cleaning body, ensuring the area | region of the press surface 27a.

  As described above, in the present embodiment, the head member 24 has the protruding portion 27b that protrudes closer to the ferrule 100 than the pressing surface 27a outside the pressing surface 27a of the distal end portion 27. And the penetration hole (the supply side insertion hole 27c and the collection | recovery side insertion hole 27d) which penetrates a cleaning body is formed in the protrusion part 27b. Thereby, the dropout of the cleaning body at the time of rotation of the head member 24 can be suppressed, and the area of the pressing surface can be expanded as compared with the comparative example.

  In the present embodiment, the protruding portion 27 b guides the head member 24 in contact with the ferrule 100. Thereby, position alignment with respect to the ferrule 100 can be performed, and the position shift of the ferrule end surface 100a and the press surface 27a can be suppressed.

  Moreover, in this embodiment, the ferrule 100 has the taper surface 100b, and the protrusion part 27b is contacting the taper surface 100b, and is guiding the head member 24. FIG. Thereby, alignment can be made easier.

  Moreover, in this embodiment, the protrusion amount from the pressing surface 27a of the protrusion part 27b is set larger than the diameter of the cleaning body. Thereby, the protrusion part 27b can be made to contact the ferrule 100, and position alignment becomes possible.

=== Others ===
The above-described embodiments are for facilitating the understanding of the present invention, and are not intended to limit the present invention. The present invention can be modified and improved without departing from the gist thereof, and it goes without saying that the present invention includes equivalents thereof.

  In the above-described embodiment, the protruding portion 27b is provided in an annular shape so as to surround the periphery of the pressing surface 27a, but is not limited thereto. For example, you may partially protrude in several places (at least 2 places including the formation part of the supply side insertion hole 27c and the collection | recovery side insertion hole 27d) around the press surface 27a.

  In the above-described embodiment, the two insertion holes (the supply-side insertion hole 27c and the recovery-side insertion hole 27d) are each formed only in the protruding portion 27b. However, at least a part of the insertion hole is formed in the protruding portion 27b. It only has to be done. For example, the insertion hole may be formed in a range straddling the protruding portion 27b and the pressing surface 27a. Even in this case, since the thickness of the outer periphery of the insertion hole is located at the protruding portion 27, it is possible to prevent the cleaning body from falling off while securing the area of the pressing surface 27a. Therefore, the area of the pressing surface can be increased as compared with the comparative example.

  In the above-described embodiment, the supply-side guide groove 27e and the collection-side guide groove 27f are formed in a tapered shape that is inclined with respect to the front-rear direction. However, the present invention is not limited to this. For example, it may be parallel to the front-rear direction (the groove depth is constant). Alternatively, the depth of the groove may be changed stepwise. In addition, the formation position of the two insertion holes (the supply side insertion hole 27c and the recovery side insertion hole 27d) can be separated by making the groove shallow on the front side. That is, the area of the pressing surface can be expanded. Further, by deepening the groove on the rear side, the cleaning body can be made difficult to come out.
