FIGS. 1-24 is a figure which shows one Embodiment of the optical connector cleaning tool (it also serves as an optical component cleaning tool. Hereinafter, only a "cleaning tool") of this invention.

  As shown in FIG. 10, an optical connector plug 60 (hereinafter simply referred to as an optical connector) and an optical connector adapter 70 (connector housing) to which the cleaning tool 1 of the present embodiment is applied are here JIS C 5982. MPO type optical connector (MPO: Multifiber Push On).

The optical connector 60 is an optical connector having a configuration in which an MT type optical connector ferrule 61 (MT: Mechanically Transferable; hereinafter simply referred to as a ferrule) defined in JIS C 5981 or the like is made of plastic and accommodated in a distal end portion of a sleeve-like housing 62. It is a plug, and the whole is formed in a cross-sectional shape with a flat outer appearance.
In the following description, the direction corresponding to the flat short side of the ferrule 61 of the optical connector 60 (the vertical direction in FIG. 10) is the thickness direction, and the direction corresponding to the long side is the width direction (the horizontal direction in FIG. 10). ). The optical connector adapter 70 connected to the optical connector 60 and the insertion portion 4 (described later) of the cleaning tool 1 inserted into the optical connector adapter 70 corresponding to the thickness direction and the width direction of the ferrule 61 are also described. Similarly, it may be referred to as a thickness direction and a width direction.

As shown in FIG. 14, a predetermined number (four in this case) of optical fiber holes 61 b (fine holes) are opened near the center position 66 of the joining end surface 61 a of the ferrule 61. Here, the optical fiber 63 is a four-core optical fiber ribbon, and the optical fiber 63a (bare optical fiber) formed by removing the resin coating at the tip is inserted into the optical fiber hole 61b of the ferrule 61. Accordingly, the optical connector 60 is terminated so as to be able to butt-connect with other optical connectors, and is drawn out from the rear end of the optical connector 60 through the inside of the optical connector 60.
In FIG. 10, reference numeral 64 is a boot, and 68 is a coupling.
The optical fiber 63 is not particularly limited as long as it is suitable for termination with the optical plug. For example, a single-core or multi-core optical fiber, and this optical fiber is housed in a tube. An optical fiber cord or the like can be used.
The number of cores of the multi-core optical fiber ribbon is not limited to the aforementioned four cores. The optical fiber tape core may be a single core. Further, the number of cores supported by the ferrule 61 is not limited (single cores are also possible).

  On the joint end face 61a of the ferrule 61, guide pin holes 61c are provided on both sides of the optical fiber hole 61b on the outer side in the width direction. The ferrules 61 are positioned with high accuracy by a well-known guide pin fitting type positioning mechanism via a protruding member 65 (guide pin) provided so as to be inserted into the guide pin hole 61c and protrude from the joining end surface 61a. Thus, the end faces of the optical fiber 63a are butt-joined and connected. As a result, the optical fibers 63 terminated at the ferrules 61 are optically connected to each other.

The optical connector adapter 70 is formed in a sleeve shape in which both sides of the connector accommodation hole 72 are opened as connector insertion holes 71, and the optical connector 60 is accommodated in the connector accommodation hole 72 by inserting the optical connector 60 from the connector insertion hole 71. Can be done.
The optical connector adapter 70 in the present invention is a generic term for relay devices that position and fix the optical connectors 60 on both sides. Therefore, the optical connectors 60 on both sides connected to the optical connector adapter 70 are not limited to those having the same shape. Even if optical plugs having different shapes can be connected, they are called optical adapters.

When the optical connector 60 is inserted into the connector receiving hole 72 from the connector insertion openings 71 on both sides of the optical connector adapter 70, the ferrules 61 are abutted with each other in the optical connector adapter 70, thereby being terminated at each ferrule 61. The optical fibers 63 are optically connected to each other.
This type of optical connector 60 has a built-in spring (not shown) for applying a butt force between the ferrules 61.

  The inner wall 70a of the optical connector adapter 70 is provided with a key groove that can be fitted to a key 62a that protrudes from one side surface in the thickness direction of the housing 62 of the optical connector 60. The key 62a and the key groove 72a are formed only on one side surface in the thickness direction of the housing 62 of the optical connector 60 and the connector insertion port 71 of the optical connector adapter 70, and the key 62a can be inserted into the key groove 72a. The optical connector 60 can be inserted into the optical connector adapter 70 only in the direction.

  Further, the optical connector adapter 70 is provided with elastic claws that are detachably engaged with the housing 62 of the optical connector 60 inserted into the connector insertion port 71. On the side surfaces of both sides in the width direction of the housing 62 of the optical connector 60, a concave groove 69 that guides the elastic claw of the optical connector adapter 70 and an engagement recess (not shown) in which the elastic claw is detachably engaged. ) Is provided.

(Overall configuration of cleaning tool)
Next, the cleaning tool 1 will be described.
The cleaning tool 1 can be applied to cleaning the joining end surface 61a of the optical connector 60.
In the present invention, the optical connector (optical component) to be cleaned is not necessarily limited to the optical connector plug of the MPO optical connector. For example, it is possible to adopt a configuration in which a portion (ferrule portion) that can function as an MT ferrule (MT type optical connector) adopts a housing in which resin is integrally molded.
In this specification, the joining end surface 61a of the ferrule 61 may be referred to as the joining end surface 61a of the optical connector 60 in some cases.

FIG. 5 is a diagram showing the relationship between the take-up disk of the drive unit 5 and the ratchet pawl, and FIG. 6 shows the vicinity of the insertion unit 4 (described later) inserted into the optical connector adapter 70. (A) is a plan sectional view, (b) is a front sectional view, (c) is a view of the insertion portion 4 as viewed from the distal end side (the side pressed against the joining end surface 61a of the optical connector 60), FIG. 7 is a plan sectional view showing the cassette 3 housed in the tool main body 10 of the cleaning tool 1, FIG. 8 is a front sectional view showing the cassette 3, and FIG. 9 is a relationship between the cleaning tape 2 and the head member 420 of the insertion portion 4. FIG.

  As shown in FIGS. 1 to 4, the cleaning tool 1 includes a case-shaped tool body 10, a supply reel 31 and a take-up reel 32 around which a cleaning tape 2 is wound, and is taken out into the tool body 10. The cassette 3 that can be stored, the insertion portion 4 that protrudes from the tool body 10 and is inserted into the optical connector adapter 70, and the take-up reel 32 of the cassette 3 that is stored in the tool body 10 are provided. And a drive unit 5 for rotational driving.

(Tool body)
As shown in FIG. 1, the tool body 10 includes a cassette housing part 13 for housing the cassette 3 and a cylindrical projecting cylinder part 14 projecting from the cassette housing part 13.
The tool body 10 is tapered from the cassette housing part 13 toward the protruding cylinder part 14. The tip of the cylindrical protrusion 14 protruding from the cassette housing part 13 functions as an insertion part fitting part 14 a for attaching the insertion part 4.

The cassette housing portion 13 has a flat case shape. The tool body 10 as a whole can also be said to have a flat case shape.
The tool body 10 has a split structure in which a pair of case halves 11 and 12 are integrated.

The case halves 11 and 12 can be integrated and separated.
The tool body 10 can be disassembled by separating the pair of case halves 11 and 12 constituting the tool body 10 integrally. The cassette housing part 13 and the protruding cylinder part 14 are also disassembled into two parts.
When the pair of case halves 11 and 12 are integrated, the tool body 10 is assembled. In FIG. 1, reference numerals 15 a and 15 b denote screws for integrating the pair of case halves 11 and 12. If the screws 15a and 15b are loosened and removed, the tool body 10 can be disassembled by separating the pair of case halves 11 and 12.

As means for integrating the pair of case halves 11 and 12 (fixing means for integration), an engaging claw (elastic claw), a fitting portion, and the like can be employed in addition to the above-described screws.
The engaging claw (elastic claw) is formed in one case half and detachably engages with the other case half, and the fitting portion is formed in one case half. A press-fit pin protruding from the other case half is fitted into the pin hole by press-fitting, and the press-fit pin fitted into the pin hole can be extracted from the pin hole by pulling artificially. Things, etc.
However, as the fixing means for integration, one that enables separation and integration of the pair of case halves 11 and 12 is employed.

Here, the tool main body 10 (specifically, the case halves 11 and 12 constituting the tool main body 10) is made of plastic such as polystyrene (PS) or polyoxymethylene (POM, polyacetal).
The tool body 10 made of plastic such as polystyrene or polyoxymethylene can be incinerated after use.

(Cleaning tape)
The cleaning tape 2 and below (sometimes simply referred to as a tape) is not particularly limited, and any known appropriate cleaning cloth (nonwoven fabric or woven cloth) processed into a tape shape can be employed. Examples thereof include those made of ultrafine fibers such as polyester and nylon. The structure is also a general one with a substantially constant width.
Since this cleaning tape 2 is for removing dust and dirt from the joining end surface 61a of the ferrule 61, it is easy to catch dust and dirt, and the trapped dust and dirt are difficult to separate from the tape. It is preferable to do.

(cassette)
As shown in FIGS. 7 to 9, the cassette 3 has a structure in which a supply reel 31 and a take-up reel 32 are incorporated in a thin case-shaped outer case 33. The supply reel 31 and the take-up reel 32 are assembled and arranged in the surface direction of a thin case-shaped outer case 33.
As shown in FIGS. 2 and 3, the cassette 3 is configured such that the cylindrical shaft 31 a of the supply reel 31 is fitted to the outside of the supply reel support shaft 18 projecting in the tool body 10 (specifically, the cassette housing portion 13). The cylindrical shaft 32a of the take-up reel 32 is fitted on the outer side of the take-up shaft main body 55a of the take-up shaft 55 of the drive unit 5 assembled in the tool main body 10 (specifically, the cassette housing portion 13). In the state set in the section 5, it is stored in the tool body 10 (specifically, the cassette storage section 13).
The supply reel support shaft 18 protrudes from the inner surface side of one of the pair of case halves 11 and 12 of the tool body 10 (in the illustrated example, the case halves of reference numeral 11). The drive unit 5 is assembled to the case half 11 on the side where the supply reel support shaft 18 is projected.

The cassette 3 is accommodated in the cassette accommodating portion 13 in such a direction that the tape outlet 34 opened in the outer case 33 faces the protruding cylindrical portion 14.
The tape outlet 34 is divided into two by a partition wall 34a (tape outlets 34b and 34c). The cleaning tape 2 extending between the supply reel 31 and the take-up reel 32 is passed through tape outlets 34b and 34c partitioned by the partition wall 34a, and the middle in the longitudinal direction is outside the partition wall 34a. Be placed. Even if the length of the cleaning tape 2 pulled out from the cassette 3 is shortened, the cleaning tape 2 is caught by the partition wall 34a and does not enter the outer case 33.

The supply reel 31 includes a cylindrical shaft 31a and flange-shaped flange portions 31b protruding from both axial ends of the cylindrical shaft 31a. The take-up reel 32 has a cylindrical shaft 32a and flange-shaped flange portions 32b that protrude from both ends in the axial direction of the cylindrical shaft 32a. The cleaning tape 2 is wound around the cylindrical shafts 31a and 32a between the flanges at both ends in the axial direction of the cylindrical shafts 31a and 32a.
Further, the reels 31 and 32 have ring-shaped shaft projecting portions 31c and 32c, which are portions where the cylindrical shafts 31a and 32a extend and project outside the pair of flange portions. The reels 31 and 32 are respectively inserted into bearing holes 33c and 33d formed by penetrating the shaft projections 31c and 32c at both ends of the cylindrical shafts 31a and 32a through the face plates 33a and 33b on both the front and back sides of the outer casing 33 of the cassette 3. Inserted and rotatably supported by the face plates 33a and 33b on both sides.

The flanges 31 b and 32 b of the supply reel 31 and the take-up reel 32 are disposed inside the outer case 33 and overlapped with the face plates 33 a and 33 b of the outer case 33.
The clearances 31b and 32b of the reels 31 and 32 and the face plates 33a and 33b of the outer case 33 of the cassette 3 are lightly in contact with each other, or a minute clearance is secured so that the cleaning tape 2 cannot enter. That is, there is no gap of a size that allows the cleaning tape 2 to enter between the flange portions 31 b and 32 b of the reels 31 and 32 and the face plates 33 a and 33 b on both sides of the outer case 33. For this reason, in this cassette 3, for example, even if the cleaning tape 2 rises greatly from the reel (the supply reel 31 or the take-up reel 32) due to loosening, the cleaning tape 2 is moved from the reels 31, 32 to the reels 31, 32, There is no fear of dropping into the gap between the 32 flange portions 31b, 32b and the face plates 33a, 33b on both sides of the outer case 33.

The lifting of the cleaning tape 2 from the reel remains only inside the outer case 33 of the cassette 3.
Further, even if the cleaning tape 2 is largely lifted from the reel due to slackness, when the advancement is fed by the operation of the drive unit 5, the inner surface of the exterior case 33 removes the cleaning tape 2 lifted from the reel from the pair of reels. Since it functions as a guide surface for guiding between the parts, it fits between the pair of flange parts of the reel. Thereby, the function of feeding operation (forward feeding) of the cleaning tape 2 can be reliably maintained.

  In the cleaning tool having the conventional structure as exemplified in Patent Documents 1, 2, and 3 described above, a supply reel that fits into the supply reel support shaft of the drive unit in the tool body, and a take-up reel that fits into the take-up shaft Are not collectively stored in a cassette like the cleaning tool according to the present invention. In a conventional cleaning tool, when a strong impact force or strong vibration is applied, the cleaning tape may become loose and the cleaning tape may fall off the reel. When the cleaning tape falls off the reel, there are problems such as winding around the shaft (supply reel support shaft, take-up shaft) into which the reel is fitted, preventing forward feeding, and cutting by an unreasonable feeding operation.

On the other hand, the cleaning tool 1 according to the present invention has a structure in which the cassette 3 having a structure in which the supply reel 31 and the take-up reel 32 are incorporated is housed in the tool body 10 as described above. It is possible to easily prevent the cleaning tape 2 from falling off. It is possible to surely prevent the inconvenience that the cleaning tape 2 dropped from the reel is wound around the supply reel support shaft and the take-up shaft and cannot be fed forward.
Since the inside of the cassette 3 is not provided with a drive unit for forward feeding of the cleaning tape, a very simple structure is sufficient. For this reason, it is easy to make a structure that can prevent the cleaning tape 2 from falling off the reel by the exterior case 33 or the like.

  The outer case 33 may be configured to prevent the cleaning tape 2 from falling off the reel, and is not limited to the configuration described above. For example, a structure in which a pair of face plates are disposed between a pair of flange portions of the reel (in other words, a structure in which the pair of flange portions of the reel are disposed on the outer surface side of the double-sided plate) can be employed. .

(Insertion section)
Next, an example of the insertion unit 4 will be described.
As shown in FIGS. 3 and 6A to 6C, the insertion portion 4 includes a sleeve-like insertion housing 410 and a head member 420 incorporated inside the insertion housing 410. Yes.

The head member 420 performs a function of pressing the cleaning tape 2 against the joining end surface 61 a of the ferrule 61 of the optical connector 60 connected to the optical connector adapter 70 when the insertion portion 4 is inserted into the optical connector adapter 70. Have
In the head member 420, the cleaning tape 2 extends along the side surfaces 425 on both sides of the top and bottom of the head member 420 (up and down in FIG. 4 and up and down in FIG. 6B) from the end surface (hereinafter referred to as the front end surface 424) of the tip 422. It is wound to extend.

  The head member 420 is formed in an elongated shape that penetrates the interior of the insertion housing 410. The head member 420 has a longer axial dimension than the insertion housing 410. This head member 420 has a proximal end portion 421 on the proximal end side (the side opposite to the distal end portion 422) fixed in the insertion portion fitting hole 14a which is an opening portion at the distal end of the protruding cylindrical portion 14, and the distal end portion The part 422 is assembled to the tool body 10 with the part 422 protruding outward from the tool body 10. The distal end portion 422 slightly protrudes from the distal end of the insertion housing 410 assembled on the outside of the head member 420 (the side that is the distal end in the insertion direction with respect to the optical connector adapter 70).

  The head member 420 is accommodated in the tool body 10 by storing the fixing base end 421 on which the small protrusions 423 for preventing displacement are fitted so as to be fitted into the insertion portion fitting hole 14 a at the tip of the protruding cylinder portion 14. It is attached. The fixing base end portion 421 protrudes from the base end side (the side opposite to the tip end side) of the insertion housing 410. Since the small protrusion 423 of the fixing base end portion 421 is fitted into the mounting recess 14b formed in the inner surface of the insertion portion fitting hole 14a, the pushing of the head member 420 into the tool main body 10 and the tool main body are thereby performed. Pulling out from 10 is regulated.

  As shown in FIGS. 3 and 10, the insertion housing 410 includes an insertion sleeve portion 411 formed in an appearance similar to the housing 62 of the optical connector 60, and one axial end portion (base end portion) of the insertion sleeve 411. And an elastic claw 412 (see FIGS. 3 and 6A) that protrudes from a side opposite to the “tip”. The elastic claw 412 engages with the head member 420 in a detachable manner.

  The insertion housing 410 is positioned by the inner surface of the connector receiving hole 72 of the optical connector adapter 70 when the insertion sleeve portion 411 is inserted into the optical connector adapter 70. When the insertion housing 410 is positioned in the optical connector adapter 70, the distal end surface 424 of the head member 420 is positioned with respect to the joining end surface 61a of the ferrule 61 of the optical connector 60 in which the optical connector adapter 70 is inserted. The insertion housing 410 functions to position the front end surface 424 of the head member 420 with respect to the joining end surface 61a of the ferrule 61 of the optical connector 60 inserted into the other end of the optical connector adapter 70.

On both sides of the outer surface of the insertion housing 410 in the width direction, concave grooves 414 are formed for guiding the elastic claws in the optical connector adapter 70 when the insertion portion 4 is inserted into the optical connector adapter 70. However, since the engagement recess into which the elastic claw is engaged is not formed in the side portion of the insertion housing 410, even if the insertion housing 410 is inserted into the optical connector adapter 70, the elasticity in the optical connector adapter 70 is not obtained. It does not engage with the nail. For this reason, the insertion housing 410 can be freely inserted into and removed from the optical connector adapter 70.
In addition, the insertion housing 410 has a reverse insertion prevention key 415 that can be fitted in the key groove 72a of the optical connector adapter 70, and is protruded only on one side surface in the thickness direction. It is.

The insertion housing 410 is detachably assembled to the protruding cylinder portion 14 of the tool body 10 or the head member 420 fixed to the protruding cylinder portion 14.
As shown in FIGS. 3 and 6A, the insertion housing 410 in the illustrated example has a distal end portion (right side in FIG. 3, right side in FIG. 6A) in the insertion direction to the optical connector adapter 70. The pair of elastic claws 412 projecting in an arm shape at the base end opposite to) can be engaged with and disengaged from the engagement recesses 428 formed on both side surfaces (the left side surface and the right side surface) of the head member 420. By engaging with the head member 420, the head member 420 is detachably assembled. An engagement protrusion 413 projecting from the tip of the arm-shaped elastic claw 412 enters and engages with the engagement recess 428.
The elastic claws 412 that are engaged with the engaging recesses 428 and are arranged along the both side surfaces of the head member 420 are pressed by the inner surface of the insertion fitting hole 14a so as not to be separated from the side surface of the head member 420. As a result, the engagement of the elastic claw 412 with the head member 420 is maintained, and the extraction of the insertion housing 410 from the tool main body 10 (specifically, the protruding cylindrical portion 14) and the pushing into the tool main body 10 are restricted.

In the illustrated head member 420, the engagement recess 428 is formed in an elastic claw receiving groove 429 formed on the left and right side surfaces of the head member 420. The elastic claw storage groove 429 can store the elastic claw 412 of the insertion housing 410.
The elastic claw 412 of the insertion housing 410 is received in the elastic claw storage groove 429 and engaged with the engagement recess 428.
In the insertion housing 410, the elastic claw 412 is accommodated in the protruding cylindrical portion 14, and the insertion sleeve portion 411 is disposed at the distal end of the protruding cylindrical portion 14.

The structure for attaching the insertion housing 410 to the tool body 10 is not limited to that described above. For example, various configurations can be employed such as a configuration in which the insertion housing 410 is provided with a claw that detachably engages with an engagement portion (a concave portion or a convex portion) on the inner surface of the insertion fitting hole 14a of the protruding cylindrical portion 14. .
However, in any configuration, in view of replacement of the cleaning tape 2, the insertion portion 4 can be attached to and detached from the tool main body 10 (specifically, the protruding cylinder portion 14), and the insertion portion 4 is removed from the tool main body 10. In this state, the head member 420 can be inserted into and removed from the insertion housing 410.

The insertion portion fitting hole 14 a is located at the joint 16 of the pair of case halves 11 and 12 constituting the tool body 10.
When assembling the tool body 10 by integrating the pair of case halves 11 and 12, the fixing base end portion 421 of the head member 420 is arranged at the position where the insertion portion fitting hole 14a is formed, The fixing base end portion 421 is accommodated in the protruding cylindrical portion 14 by being inserted between the pair of case halves 11 and 12 and integrating the pair of case halves 11 and 12. The insertion housing 410 is externally attached to the head member 420 in advance.
When the tool body 10 is assembled by integrating the pair of case halves 11 and 12, the fixing base end portion 421 of the head member 420 is fixed to the protruding cylindrical portion 14, and the insertion housing 410 is also fixed to the protruding cylindrical portion 14. Will be. Thereby, the insertion part 4 is protrudingly provided by the tool main body 10 (specifically, the protrusion cylinder part 14 front-end | tip).
When the tool body 10 is disassembled by separating the pair of case halves 11 and 12, the insertion portion fitting hole 14a is opened, and the insertion portion 4 accommodated in the insertion portion fitting hole 14a is replaced with the tool body. 10 (specifically, the protruding cylindrical portion 14) can be detached.

In the illustrated tool body 10, a clamp ring 17 is detachably mounted on the outside of the protruding cylinder portion 14 as an integration fixing means for integrating the case halves 11 and 12 in the protruding cylinder portion 14. As the clamp ring 17, for example, a spring obtained by forming a metal plate into a C shape or a U shape can be used. However, as a fixing means for integration, for example, a binding tool such as an insulation lock tie can also be used. . By the clamping force of the clamp ring 17, the fixing base end portion 411 of the insertion portion 4 housed in the insertion portion fitting hole 14a is firmly fixed to the tool body 10 (specifically, the protruding cylinder portion 14).
The clamp ring 17 can be omitted.

  As shown in FIG. 6C, the portion of the cleaning tape 2 wound around the head member 420 that extends along the both side surfaces 425 of the head member 420 is the both side surfaces 425 of the head member 420. The guide member 426 is housed in a guide groove 426 that extends along the axial direction of the head member 420. The inner surface of the guide groove 426 functions as a guide surface that guides the cleaning tape 2 that is fed (moved forward) from the supply reel 31 to the take-up reel 32 by operation of the drive unit 5.

A portion of the cleaning tape 2 that extends between the supply reel 31 and the take-up reel 32 of the cleaning tape 2 is pulled around the tip portion 422 of the head member 420 from the cassette 3 to the tip of the insertion portion 4. It is hung.
The space inside the protruding cylinder portion 14 communicates with the space in the cassette housing portion 13 of the tool body 10, and the cleaning tape 2 wound around the tip portion 422 of the head member 420 is connected to the cassette 3 in the cassette housing portion 13. In other words, it is a portion that passes through the protruding cylindrical portion 14 and is pulled out to the tip portion 422 of the head member 420 at the tip of the insertion portion 4.
When the cleaning tape 2 is fed and moved so as to be wound up from the supply reel 31 to the take-up reel 32 (advance feed), the cleaning tape 2 unwound from the supply reel 31 is moved from the protruding cylinder portion 14 to one of the head members 420. Through the guide groove 430 on the side of the side surface 425a, it reaches the front end surface 424 of the head member 420, and from the front end surface 424 through the guide groove 430 on the other side surface 425b of the head member 420, By way of this, it is taken up on the take-up reel 32 of the cassette 3.

(Drive part)
As shown in FIGS. 2 to 5, the drive unit 5 is provided on the push button 51, a push button 51 that is pushed in, a return spring 52 that biases the push button 51 that is pushed in in a direction to push back, and the push button 51. A take-up disk 54 around which a pinion gear 53 meshed with the rack 51a is rotatably mounted in the tool body 10 and the take-up reel 32 of the cassette 3 is detachably fitted. A take-up shaft 55 having a take-up shaft main body 55a, and a ratchet groove 55c formed on the inner surface of the case half body 11 and formed on a flange portion 55b projecting on the outer periphery of the take-up shaft 55 are detachable. The engaging ratchet claw 56 (elastic claw; hereinafter also referred to as a reverse rotation preventing ratchet claw) is provided.
The drive unit 5 is entirely housed in the tool body 10 except that a part of the push button 51 (operation unit) protrudes outside the tool body 10.

The ratchet groove 55c and the ratchet pawl 56 of the take-up shaft 55 are rotated in the tape take-up direction of the take-up shaft 55 (that is, in the tape take-up direction of the take-up reel 32 fitted to the take-up shaft main body 55a). A reverse rotation prevention mechanism (ratchet mechanism) that permits rotation in the same direction) and restricts rotation in the direction opposite to the tape winding direction.
In the take-up reel 32, a gear 32d (see FIGS. 7 and 8) formed on the inner surface of the cylindrical shaft 32a of the take-up reel 32 is replaced with a gear (not shown) formed on the outer peripheral surface of the take-up shaft main body 55a. Engage it with the take-up shaft 55. Thereby, it rotates integrally with the winding shaft 55.
The take-up shaft 55 and the take-up reel 32 are not engaged with the ratchet groove 55c in the tape take-up direction (the rotation direction indicated by arrow A in FIGS. 4 and 5). Although it rotates by sliding, rotation is restricted by the ratchet claw 56 for preventing reverse rotation engaging with the ratchet groove 55c in the direction opposite to the tape winding direction.

  The push button 51 protrudes outside the tool body 10 and is operated so as to be pushed into the tool body 10. When the pushing force of the pushing operation is released, the urging force of the return spring 52 returns to the state of protruding to the outside of the tool body 10.

  The winding disk 54 is rotatably attached to one case half 11 of the tool body 10. The take-up disk 54 is disposed coaxially with the take-up shaft 55 and is provided so as to overlap the take-up shaft 55. Specifically, the take-up shaft 55 is superposed on the side of the take-up disk 54 that is rotatably supported by the case half 11 and faces the case half 12. The winding disk 54 and the winding shaft 55 can rotate independently of each other.

In addition to the ratchet groove 55c for preventing reverse rotation, a ratchet groove 55d for transmitting rotational force from the take-up disk 54 is also formed in the flange portion 55b of the take-up shaft 55. The ratchet groove 55d is provided around the flange portion 55b in parallel with the ratchet groove 55c at a position closer to the winding disk 54 than the ratchet groove 55c for preventing reverse rotation.
The flange portion 55b of the take-up shaft 55 is provided closer to the take-up disc 54 than the take-up shaft main body 55a. The take-up shaft main body 55a protrudes from the flange portion 55b toward the case half 12 side.

  The take-up disk 54 is a disk-like member in which the pinion gear 53 and a ratchet claw 57 (elastic claw) that removably engages with the ratchet groove 55d of the take-up shaft 55 are formed. The ratchet pawl 57 protrudes from the surface of the outer peripheral portion of the winding disk 54 facing the winding shaft 55.

  In the drive unit 5, when the push button 51 is pushed in, the take-up disk 54 is rotated by meshing the rack 51a on the push button 51 side with the pinion gear 53 on the take-up disk 54 side. The ratchet pawl 57 of the take-up disk 54 engages with the ratchet groove 55 d of the take-up shaft 55, and the take-up shaft 55 is driven and rotated by the take-up disk 54. As a result, the take-up reel 32 of the cassette 3 fitted on the take-up shaft main body 55a of the take-up shaft 55 is rotated integrally with the take-up shaft 55, whereby the cleaning tape 2 is wound on the take-up reel 32. The forward feeding of the cleaning tape 2 from the supply reel 31 to the take-up reel 32 is realized.

The ratchet pawl 57 of the take-up disk 54 is rotated when the take-up disk 54 is rotated in the tape take-up direction (rotation in the direction of arrow A in FIGS. 4 and 5) by the pushing operation of the push button 51. The winding shaft 55 is driven and rotated by the winding disk 54 by engaging with the ratchet groove 55d.
Conversely, when the take-up disk 54 is rotated in the direction opposite to the tape take-up direction as the push button 51 is pushed back to the position before the push-in operation by the urging force of the return spring 52, the take-up shaft 55 is reversed. Since the ratchet pawl 57 is slid without being engaged with the ratchet groove 55d of the winding shaft 55 that is locked so as not to reversely rotate (rotation opposite to the tape winding direction) by the preventing ratchet pawl 56, The take-up shaft 55 does not follow the disk 54.
The ratchet claw 57 of the take-up disk 54 and the ratchet groove 55d of the take-up shaft 55 cause the take-up disk 55 to be driven and rotated in the tape take-up direction when the push button 51 is pushed in. When the operated push button 51 is returned to the initial position by the return spring 52, a winding ratchet mechanism that allows the winding disk 54 to rotate with respect to the winding shaft 55 is configured.

Although illustration is omitted, the supply reel support shaft 18 is divided into a plurality of parts by a dividing groove 18a. The supply reel support shaft 18 has an outer diameter slightly larger than the inner diameter of the cylindrical shaft 31a of the supply reel 31, but is elastically deformed by the split groove 18a, so that the cylindrical shaft 31a of the supply reel 31 is deformed. It can be externally fitted by pushing.
The supply reel 31 that is pushed into the supply reel support shaft 18 and fitted outside is given rotational resistance by the supply reel support shaft 18 being pressed against the inner surface of the cylindrical shaft 31a.
The split groove 18 a and the supply reel support shaft 18 in which the split groove 18 a is formed function as a sag prevention mechanism that applies a rotational resistance to the supply reel 31 and prevents the cleaning tape 2 from sagging.
As a sagging prevention mechanism, for example, a rotation resistance generating groove or unevenness is formed on the outer peripheral surface of the supply reel support shaft 18 and / or the inner peripheral surface of the cylindrical shaft 31a of the supply reel 31. Also good.

(Assembling the cleaning tool)
To assemble the cleaning tool 1, the pair of case halves 11 and 12 of the tool body 10 are separated, and the supply reel 31 of the cassette 3 and the cylindrical shafts 31 a and 32 a of the take-up reel 32 are connected to the case half 11. The supply reel support shaft 18 protruding inward and the take-up shaft main body 55a of the take-up shaft 55 of the drive unit 5 are fitted. Next, the tool body 10 is assembled by integrating the pair of case halves 11 and 12. When assembling the tool body 10 by integrating the pair of case halves 11 and 12, the insertion portion 4 is fitted into the insertion portion fitting hole 14 a at the tip of the protruding cylindrical portion 14, and the clamp ring 17 is attached to the protruding cylindrical portion 14. Fit and fix.
Thereby, the cleaning tool 1 is assembled.

(Cleaning the optical connector end face)
In order to clean the joining end surface 61a of the ferrule 61 of the optical connector 60 that is inserted and connected to one side of the optical connector adapter 70 using the cleaning tool 1, as shown in FIG. 4 is inserted into the optical connector adapter 70 from the side opposite to the side to which the optical connector 60 is connected. Then, the push button 51 is pushed in while the cleaning tape 2 is pressed against the joining end surface 61 a of the ferrule 61 of the optical connector 60. As a result, the cleaning tape 2 is advanced from the supply reel 31 to the take-up reel 32, and the joining end surface 61a is cleaned.
The cleaning tape 2 is slid and moved with respect to the joint end surface 61a of the ferrule 61 by forward feed, so that dust or the like on the joint end surface 61a is removed like wiping and cleaning.

  As described above, the insertion portion 4 of the cleaning tool 1 is inserted into the optical connector 60 in the connector housing hole 72 of the optical connector adapter 70 according to the external shape of the insertion housing 410 corresponding to the housing 62 of the optical connector 60. On the other hand, the optical connector adapter 70 is positioned in the same manner as the optical connector (optical connector plug) inserted and connected from the opposite side. Thereby, the front end surface 424 of the head member 420 of the insertion portion 4 is positioned at a position facing the joining end surface 61a of the ferrule 61 of the optical connector 60, and the cleaning tape 2 wound around the head member 420 is attached to the head member. The front end surface 424 of 420 can be pressed against the joining end surface 61 a of the ferrule 61.

As the ferrule 61 at the tip of the optical connector 60, a guide pin 65 for high-precision positioning of the ferrules 61 to be butt-connected is protruded from the joining end surface 61a, and an empty guide pin 65 is not fitted. A guide pin hole 61c (a guide pin hole 61c in which no guide pin 65 is inserted) may be opened in the joining end surface 61a.
As shown in FIGS. 6 (c) and 10, a guide pin housing hole into which a guide pin 65 protruding from the joining end surface 61 a of the ferrule 61 is inserted into the distal end portion 422 of the head member 420 of the insertion portion 4. Two 427 are formed. The guide pin accommodation hole 427 is opened in the front end surface 424 of the head member 420. The guide pin accommodation hole 427 accommodates the guide pin 65 projecting from the joining end surface 61a of the ferrule 61 when cleaning the joining end surface 61a of the ferrule 61 of the type in which the guide pin 65 projects from the joining end surface 61a. Thus, the cleaning tape 2 can be pressed against the joining end surface 61 a of the ferrule 61 of the optical connector 60 by the front end surface 424 of the head member 420.
Therefore, according to the cleaning tool 1, even when the joining end surface 61 a of the ferrule 61 of the type in which the guide pin 65 protrudes from the joining end surface 61 a is cleaned, the insertion portion 4 inserted into the optical connector adapter 70 can be used. The front end surface 424 of the head member 420 can reliably press the cleaning tape 2 against the joining end surface 61a of the ferrule 61 of the optical connector 60, and the joining end surface 61a is cleaned with a ferrule on which the guide pin 65 is not provided. This can be done in the same way as 61.

The cleaning tape 2 is pressed against the central portion of the joining end surface 61a of the ferrule 61, that is, the portion including the region where the optical fiber hole 61b is opened in the joining end surface 61a.
As described above, the cleaning tape 2 wound around the front end portion 422 of the head member 420 is accommodated in the guide groove 430 of the head member 420 and guided to the inner surface of the guide groove 430 in the insertion portion 4. Since the feed movement (forward feed) is performed, there is no concern that the installation position on the front end surface 424 of the head member 420 is shifted due to the forward feed.

When the push button 51 is pressed once, the cleaning tape 2 is advanced by a minimum feed amount (length) necessary for cleaning the joining end surface 61a of the ferrule 61 or a feed amount slightly longer than that. The
Thereby, the joining end surface 61a of the ferrule 61 can be reliably cleaned.

When the pushing force of the push button 51 that has been pushed in is released, the push button 51 is pushed back to the initial position before the pushing operation by the biasing force of the return spring 52. At this time, the take-up disk 54 on which the pinion gear 53 meshed with the rack 51a is rotated in the direction opposite to the tape take-up direction by the movement of the rack 51a accompanying the push-back of the push button 51. The winding shaft 55 rotates in the direction opposite to the tape winding direction by the engagement of the reverse rotation preventing ratchet 56 protruding from the case half 11 and the reverse rotation preventing ratchet groove 55c of the winding shaft 55. In addition, the take-up ratchet pawl 57 protruding from the take-up disk 54 slides without engaging with the take-up ratchet groove 55d of the take-up shaft 55. As a result, the take-up shaft 55 does not rotate at the position when the push-in operation of the push button 51 is completed, and the take-up disk 54 is relative to the take-up shaft 55 and is opposite to the tape take-up direction. Rotate to.
By restricting the rotation of the winding shaft 55 in the direction opposite to the tape winding direction, it is possible to prevent unnecessary slack from being formed in the cleaning tape 2. Moreover, it can prevent reliably that the part already contacted with the joining end surface 61a of the ferrule 61 among the cleaning tapes 2 contacts the joining end surface 61a again. Thereby, the inconvenience that dust, dust, etc. adhering to the cleaning tape 2 move to the joining end surface 61a can be prevented.

If the drive unit 5 is configured to convert the pushing operation of the push button 51 into the feed movement of the cleaning tape 2 by the rack-pinion mechanism, the manual rotation operation of the operation dial as disclosed in Patent Documents 1 to 3 is performed. In the drive unit configured to feed and move the cleaning tape by means of, there is an advantage that the drive unit can be downsized compared to the case where a large operation dial is required to secure the feed amount of the cleaning tape. .
Further, since the feed amount necessary for one cleaning can be secured on the cleaning tape by a single pressing operation of the push button 51, it is compared with the drive unit configured to manually rotate the operation dial of Patent Documents 1 to 3. Thus, it is easy to avoid inconveniences such as causing the cleaning tape 2 to advance forward unnecessarily and insufficient feed amount.

  It should be noted that the feed amount of the cleaning tape 2 by a single pressing operation of the push button 51 does not necessarily have a length just enough for one cleaning of the joining end surface 61a of the ferrule 61. For example, the push button 51 By performing the pushing operation of a predetermined number of times (a plurality of times), the feed amount may be sufficient for one cleaning.

  When the cleaning of the joining end surface 61 a of the ferrule 61 is completed, the insertion portion 4 of the cleaning tool 1 is pulled out from the optical connector adapter 70.

(Replacement of cleaning tape)
In order to replace the cleaning tape 2 in the cleaning tool 1, the tool body 10 may be disassembled into two case halves 11 and 12 and the cassette 3 may be replaced.
In order to replace the cassette 3, first, the used cassette 3 is taken out from the cassette storage unit 13. Further, the insertion portion 4 is removed from the tool body 10, the head member 420 is taken out from the insertion housing 410 of the insertion portion 4, and the cleaning tape 2 wound around the tip portion 422 of the head member 420 is detached from the head member 420. Let As a result, the cassette 3 can be removed from the tool body 10. The cleaning tape 2 wound around the head member 420 so as to be pulled into the insertion portion 4 from the cassette housing portion 13 can be taken out from the tool body 10 without leaving.

When the removal of the cassette 3 and the cleaning tape 2 stored in the tool body 10 is completed, the new cassette 3 is stored in the cassette storage unit 13. Further, the cleaning tape 2 drawn out from the tape outlet 34 of the cassette 3 is wound around the head member 420 of the insertion portion 4, and the head member 420 is assembled into the insertion housing 410 to assemble the insertion portion 4.
Thereafter, as in the case where the cassette 3 is housed in the tool main body 10, the tool main body 10 is assembled, and the insertion portion 4 is fixed to the tool main body 10, whereby the replacement operation of the cleaning tape 2 is completed.

According to the cleaning tool 1 according to the present invention, the supply reel 31 and the take-up reel 32 can be integrated into the tool body 10 by housing the cassette 3 in the tool body 10. Further, the supply reel 31 and the take-up reel 32 can be exchanged together by exchanging the cassette 3.
For this reason, it is difficult to cause a disadvantage that the cleaning reel 2 is soiled by dropping the supply reel and / or the take-up reel during the operation of assembling or replacing the reel in the tool body 10.
Further, the cleaning tape 2 remains stored in the cassette 3 unless it is pulled out from the tape outlet 34 of the cassette 3. For this reason, as in the prior art in which the supply reel and the take-up reel are individually stored in the tool body, the cleaning tape wound around the supply reel is unnecessarily unwound during the storing operation, and cleaning is performed. It is possible to avoid the disadvantage that the tape is damaged or soiled by twisting or bending. That is, it is possible to easily protect and maintain the cleaning tape 2 during the storing operation.

(Mode in which three cleaning tapes are grouped)
In embodiment mentioned above, the cleaning tool which applies the one strip | belt-shaped cleaning tape 2 was illustrated.
As shown in FIGS. 13 and 16, the cleaning tool according to the present invention may apply three cleaning tapes arranged side by side as a set of cleaning tapes.
The set of three cleaning tapes illustrated here includes a cleaning tape 2A for cleaning a central region E1 which is a portion located between the guide pin holes 61c in the joining end surface 61a of the optical connector shown in FIG. This is composed of cleaning tapes 2B and 2C for cleaning outer regions E2 and E2 located outside the central region E1 through pin holes 61c.

The widths of the cleaning tapes 2A, 2B, 2C are adjusted to the widths of the areas E1, E2 to be cleaned. Here, the width of the cleaning tape 2A for cleaning the central region E1 is wider than the width of the cleaning tapes 2B and 2C for cleaning the outer region E2.
The material of the cleaning tapes 2 </ b> A to 2 </ b> C (hereinafter sometimes simply referred to as a tape) is the same as that of the cleaning tape 2 described above.

  As shown in FIG. 16, the cleaning tapes 2 </ b> A, 2 </ b> B, and 2 </ b> C are independent cleaning tapes that are separated from each other. There is a gap 2S between the cleaning tape 2A in the center of the figure and the cleaning tapes 2B and 2C on both sides. Thereby, even in the case of the optical connector 60 in which the guide pin 65 is inserted into the guide pin hole 61c and protrudes from the joining end face 61a, the guide pin 65 escapes into the gap 2S between the cleaning tapes 2A to 2C, and the joining end face 61a The central region E1 and the outer regions E2, E2 can be efficiently cleaned simultaneously. That is, the gap 2S functions as a protruding member escape portion.

In the supply reel 31 and the take-up reel 32 of the cassette 3, three cleaning tapes 2 </ b> A, 2 </ b> B, and 2 </ b> C are wound side by side and arranged (in parallel) in the tape storage space between the pair of flanges.
The three cleaning tapes 2A, 2B, and 2C extend from the supply reel 31 to the take-up reel 32 in the tool body 10 while maintaining the parallel state. Even when the forward feeding from the supply reel 31 to the take-up reel 32 is performed, the three reels are always kept in parallel.

12-14 and 16 show an example of the insertion portion 20 having a structure corresponding to a set of three cleaning tapes.
The illustrated insertion portion 20 includes an insertion housing 410 and a head member 21 accommodated in the insertion housing 410.
The head member 21 includes a head main body 23 having a front end surface 24 for pressing the cleaning tape 2 against the joining end surface 61a of the optical connector 60 to be cleaned when the insertion portion 20 is inserted into the optical connector adapter 70, and the head main body. And a support mechanism 40 that supports the head body 23 and is connected to the back surface 27 side of the head body 23 that is opposite to the tip surface 24.

Here, the head member 21 is a one-part resin molded product in which the head main body 23 and the support mechanism 40 are integrally molded. The head member 21 can be manufactured from a plastic such as polyoxymethylene (POM) using an appropriate molding method.
As shown in FIGS. 12 and 16, the head body 23 has a substantially square tip surface 24, and can effectively ensure a contact area with the joining end surface 61 a of the optical connector 60. The head member 21 is incorporated into the insertion housing 410 such that the vicinity of the distal end surface 24 of the head body 23 slightly protrudes from the distal end of the insertion housing 410.

The head main body 23 is formed with a pair of guide pin accommodation holes 23 a that can receive and accommodate the guide pins 65 protruding from the joining end surface 61 a of the ferrule 61 to be cleaned, and that are opened in the distal end surface 24.
Guide grooves 25A and 25B that guide the feeding of the cleaning tapes 2A to 2C wound around the head main body 23 on both sides of the head main body 23 (here, the upper and lower sides of the head main body 23 in FIGS. 12 and 13B). , 25C. These guide grooves 25A, 25B, and 25C function as a tape positioning mechanism.
Although not shown, the cleaning tapes 2A to 2C are also inserted into both side portions of the fixing base end portion 43 (here, both upper and lower sides of the fixing base end portion 43 in FIGS. 12 and 13B). Guide grooves are provided.

  The longitudinal direction of the cleaning tapes 2 </ b> A to 2 </ b> C is disposed on the front end surface 24 of the head body 23. In the guide grooves 25A, 25B, 25C on one side of the head main body 23, among the cleaning tapes 2A to 2C, the upstream side in the tape feeding direction from the front end surface 24 of the head main body 23 (the supply reel 31 side; here FIG. 12). FIG. 13 (b) lower side) is stored. The guide grooves 25A, 25B, and 25C on the other side of the head main body 23 include, on the downstream side in the tape feeding direction from the front end surface 24 of the head main body 23 (the take-up reel 32 side. FIG. 12, the upper side of FIG.

  As shown in FIGS. 12, 13 (a) and 13 (b), the support mechanism 40 is connected to the tilting spring 41 protruding from the recess 27 a formed on the back surface 27 of the head body 23, and the tilting spring 41. And a plate-like fixing base end portion 43 connected to the side opposite to the tilting spring 41 of the compression spring 42.

When the insertion portion 20 in which the head member 21 is housed in the insertion housing 410 is assembled at the distal end of the protruding cylinder portion 14, the fixing base end portion 43 that protrudes toward the base end portion of the insertion housing 410 is used as the tool body 10. It is removably fitted in the mounting recess 14b formed on the inner surface of the projecting cylindrical portion 14 of the. Thereby, the head member 21 is positioned and attached to the tool main body 10 (specifically, the protruding cylinder portion 14).
Various mounting structures can be employed for the insertion housing 410, such as the one using the elastic claw that engages the head member from both sides as described above.
The head member 21 is not limited to the configuration that is attached to the tool body 10, and a configuration in which the head member 21 is attached to the insertion housing 410 by engaging or disengaging engagement claws can be employed. However, one that allows the head member 21 to be inserted and removed from the proximal end side of the insertion housing 410 is employed.

The shape of the tilting spring 41 is not particularly limited. Here, as shown in FIGS. 12, 13A, and 13B, the tilting spring 41 has a curved plate shape (specifically, a U-shaped plate shape). ).
The compression spring 42 functions as a connecting portion that connects the tilting spring 41 and the fixing base end portion 43 so as to be extendable and contractible.
Here, the compression spring 42 includes a spring coupling block 42c and a pair of wave springs 42a extending from the spring coupling block 42c. The pair of wave springs 42a are arranged symmetrically in the width direction of the insertion portion 20 (the vertical direction in FIG. 13A). One end of the pair of wave springs 42 a is coupled to the spring coupling block 42 c and the other end is coupled to the fixing base end portion 43.
In FIGS. 13A and 13B, reference numeral 28 a denotes a stopper wall protruding from the insertion housing 410. The stopper wall 28a abuts the spring connecting block 42c from the cassette housing portion 13 side, thereby restricting the elastic deformation of the support mechanism 40, and the protruding amount of the head body 23 from the insertion housing 410 becomes excessive. To prevent that.

  The tilting spring 41 and the pair of wave springs 42a of the compression spring 42 are coupled via a spring coupling block 42c. The tilting spring 41 extends from the spring connecting block 42c in the direction opposite to the pair of wave springs 42a. Further, the connecting position of the tilting spring 41 in the spring connecting block 42c is located at an intermediate point between the connecting positions of the wave springs 42a connected to the spring connecting block 42c at two locations separated from each other.

  When the insertion portion 20 is inserted into the optical connector adapter 70 and the cleaning tape 2A to 2C is pressed against the joining end surface 61a of the optical connector 60 to be cleaned by the head member 21, the tilt spring 41 and the compression spring 42 are Due to the elastic deformation of at least the compression spring 42, an urging force that presses against the joining end surface 61a of the optical connector 60 to be cleaned acts on the cleaning tapes 2A to 2C. The pair of wave springs 42 a of the compression spring 42 is compressed and deformed (elastically deformed) in the insertion housing 410.

Further, since the pair of wave springs 42a of the tilt spring 41 and the compression spring 42 can be elastically deformed, the tilt of the optical connector 60 in the optical connector adapter 70 (for example, the tilt of the joining end surface 61a due to the tilt of the ferrule 61) and the like. Even if it occurs, uneven distribution of the urging force that urges the front end surface 24 of the head main body 23 toward the joining end surface 61 a of the ferrule 61 can be prevented. Thereby, the urging | biasing force which presses each cleaning tape 2A-2C to the joining end surface 61 of the optical connector 60 can be kept uniform.
The elastic deformation of the tilting spring 41 and the compression spring 42 causes damage to the joining end surface 61a due to excessive pressing force of the head body 23 against the joining end surface 61a of the optical connector 60, and damage or deformation of the optical connector 60. It also plays a role to prevent such inconveniences.

The insertion portion 20 can tilt the head body 23 by elastic deformation of the tilting spring 41.
Accordingly, for example, even when the joining end surface 61a of the optical connector 60 is obliquely polished with respect to the optical axis (see FIG. 14), if the head body 23 is pressed toward the joining end surface 61a of the optical connector 60, By the tilting of the head main body 23, the direction of the front end face 24 of the head main body 23 matches the joining end face 61 of the optical connector 60 (the front end face 24 and the joining end face 61 are made parallel), and the cleaning tapes 2A to 2C are attached. It can be reliably pressed against the joining end surface 61 of the optical connector 60. The equalizing of the urging force that presses the cleaning tapes 2A to 2C against the joining end surface 61 of the optical connector 60 is also achieved.

That is, the tilting spring 41 having a curved plate shape (specifically, a U-shaped plate shape) has a curved portion with the virtual axis extending in the width direction of the insertion portion 20 as the center of the bending radius. It is formed in a curved plate shape.
When the head body 23 is pressed toward the obliquely polished joining end surface 61a of the optical connector 60, the tilting spring 41 is elastically deformed (the tilting spring 41 is deformed so that the bending radius is reduced). Of the head member 21, the connecting portion 41 a between the tilting spring 41 and the head main body 23 and the connecting portion 41 c between the tilting spring 41 and the spring connecting block 42 c are deformed so as to extend in the width direction of the insertion portion 20. By functioning as an extending virtual rotation axis, the head main body 23 tilts so that the front end surface 24 of the head main body 23 is oriented along the joining end surface 61 a of the optical connector 60.
The tilting spring 41 is also deformed so that the central portion 41b in the extending direction of the tilting spring 41 between the connecting portions 41a and 41c functions as a virtual rotation axis extending in the width direction of the insertion portion 20. This contributes to the smooth tilting of the head body 23.

  The support mechanism 40 has a function as an urging means for elastically urging the cleaning tapes 2A to 2C to the joining end surface 61a of the optical connector 60 by the head body 23, and a head body corresponding to the joining end surface 61a of the optical connector 60. 23 as long as it has a function as an inclination support means for making the inclination angle 23 variable, as long as it has the above two functions, it is not limited to the structure described above, and has various structures. Can be adopted.
