[0008] [Problem that this disclosure aims to solve] When the coating of an optical fiber is removed by the coating remover, the optical fiber is placed on a heater of the optical fiber mounting section. However, the coating of the optical fiber is sometimes removed in a dark place. In a dark place, the optical fiber placed on the optical fiber mounting section may not be easily visible. When removing the coating from multiple optical fibers such as an intermittent tape, the multiple optical fibers may need to be aligned on the optical fiber mounting section in order to avoid breakage. Therefore, it is required to improve the visibility of the optical fiber placed on the optical fiber mounting section.

[0009] [Effects of this disclosure] According to the present disclosure, it is possible to improve the visibility of the optical fiber core placed on the optical fiber mounting portion.

[0010] [Description of the embodiments of the present disclosure] The embodiments of the present disclosure will be described below. A coating remover according to one embodiment includes: (1) an optical fiber mounting section on which a coated optical fiber is mounted and which has a first blade for cutting the coating, a cover section which is openable and closable relative to the optical fiber mounting section and which has a second blade that faces the first blade when closed relative to the optical fiber mounting section, and a light diffusing section which irradiates diffused light onto the optical fiber mounted on the optical fiber mounting section. The optical fiber mounting section has a mounting surface on which the optical fiber is mounted, and the light diffusing section irradiates diffused light obliquely downward toward the mounting surface.

[0011] This sheath remover has an optical fiber mounting section and a lid section. The optical fiber mounting section has a first blade for cutting the sheath, and the lid section has a second blade facing the first blade. The optical fiber mounting section has a mounting surface on which the coated optical fiber is mounted. The sheath remover has a light diffusion section that irradiates diffused light onto the optical fiber mounted on the mounting surface of the optical fiber mounting section. When the light diffusion section irradiates the optical fiber with diffused light, the optical fiber can be irradiated evenly compared to light with a strong linearity such as light from an LED. Therefore, the visibility of the optical fiber mounted on the mounting surface can be improved. The light diffusion section irradiates diffused light obliquely downward toward the mounting surface of the optical fiber mounting section. When the diffused light is irradiated obliquely downward toward the mounting surface, the visibility of the optical fiber mounted on the mounting surface can be improved compared to when the diffused light is irradiated horizontally.

[0012] (2) In the above (1), the light diffusion section may be provided in a wall section aligned with the optical fiber mounting section along the direction in which the optical fiber core wire mounted on the optical fiber mounting section extends. The light diffusion section may be disposed in a hole recessed in the wall section in a direction away from the optical fiber mounting section. In this case, since the light diffusion section is disposed in a hole formed in the wall section, it is possible to suppress the intrusion of water or the like into the light diffusion section. Therefore, it is possible to protect the light diffusion section from moisture or the like.

[0013] (3) In the above (2), the light diffusion section may have a first protrusion protruding in a direction away from the optical fiber mounting section and a second protrusion protruding downward, and each of the first protrusion and the second protrusion may fit into the hole. In this case, the first protrusion and the second protrusion of the light diffusion section fit into the hole of the wall section, so that the light diffusion section can be firmly fixed to the wall section.

[0014] (4) In the above (2) or (3), the hole may have a lower surface extending below the light diffusion section, and the lower surface may extend diagonally downward as it moves away from the light diffusion section. In this case, even if water droplets or the like enter the hole, the water droplets or the like flow diagonally downward along the lower surface so as to move away from the light diffusion section and exit the hole. Therefore, the light diffusion section can be protected from water droplets or the like.

[0015] [Details of the embodiment of the present disclosure] Specific examples of the sheath remover according to the embodiment of the present disclosure will be described below with reference to the drawings. The present invention is not limited to these examples, but is indicated by the claims, and is intended to include all modifications within the scope of the claims. In the description of the drawings, the same or corresponding elements are given the same reference numerals, and duplicated descriptions are omitted as appropriate. The drawings may be partially simplified or exaggerated for ease of understanding, and the dimensional ratios and the like are not limited to those described in the drawings.

[0016] Fig. 1 is a perspective view showing a sheath remover 1 according to one embodiment. Fig. 2 is a perspective view showing the sheath remover 1 on which an optical fiber holder H is placed, which holds an optical fiber F from which the sheath remover 1 removes the sheath. Fig. 3 is a perspective view showing an internal structure of the sheath remover 1 shown in Fig. 1. The optical fiber F has, for example, a glass fiber and a resin sheath that covers the glass fiber.

[0017] The coating remover 1 is a device that removes the coating from the optical fiber F. The diameter of the optical fiber F (the outer diameter of the coating of the optical fiber F) is, for example, 180 μm or more and 400 μm or less. The optical fiber holder H may hold a plurality of optical fibers F, and the coating remover 1 may perform coating removal on a plurality of optical fibers F at once. The plurality of optical fibers F may be optical fiber tape core wires, such as intermittent tapes.

[0018] For example, the sheath remover 1 includes a holder holding part 10 and a main body part 20. The holder holding part 10 includes a holder placement part 11 on which an optical fiber holder H that holds an optical fiber core F is placed, and a lid part 12 that can be opened and closed with respect to the holder placement part 11. The optical fiber holder H holds an end part of the optical fiber core F. The length of the part of the optical fiber core F from which the sheath is removed is adjusted by adjusting the position at which the optical fiber holder H holds the optical fiber core F. In the following, the direction in which the lid part 12 is closed on the holder placement part 11 is defined as a first direction D1, and the direction in which the lid part 12 is opened from the holder placement part 11 is defined as a second direction D2. For example, the sheath remover 1 extends in an extension direction A in which the optical fiber core F extends, and has a width in a third direction D3 that intersects both the first direction D1 and the second direction D2.

[0019] The holder holding part 10 and the main body part 20 are aligned along the extending direction A. The main body part 20 is connected to an end part of the holder holding part 10 in the extending direction A. The holder holding part 10 has a slide shaft 13 extending to the main body part 20. The holder holding part 10 has two slide shafts 13, and the two slide shafts 13 are aligned along the third direction D3. The main body part 20 has a slide hole into which the holder holding part 10 is inserted. The main body part 20 has two slide holes, and the two slide holes are aligned along the third direction D3. The slide shaft 13 is slidably inserted into the slide hole formed in the main body part 20. This allows the holder holding part 10 to slide freely in the direction approaching and moving away from the main body part 20. In the following, the direction in which the holder holding portion 10 is moved away from the main body portion 20 may be referred to as front, forward or front side, and the direction in which the holder holding portion 10 is moved closer to the main body portion 20 may be referred to as rear, rear or rear side.

[0020] The holder holding part 10 holds an optical fiber holder H that holds an optical fiber core F. The holder holding part 10 has a hinge 14 that allows the lid part 12 to be opened and closed relative to the holder mounting part 11. The hinge 14 extends along the extending direction A at an end of the holder holding part 10 opposite the third direction D3. The lid part 12 rotates about the hinge 14, so that the lid part 12 can be opened and closed relative to the holder mounting part 11. The holder holding part 10 holds the optical fiber holder H mounted on the holder mounting part 11 by sandwiching it between the holder mounting part 11 and the lid part 12.

[0021] The main body 20 has a coating removal section 22 which is a section for removing the coating of the optical fiber F, and an operation section 23 which operates the coating removal by the coating removal section 22. The coating removal section 22 and the operation section 23 are aligned along the extending direction A. The coating removal section 22 is located between the operation section 23 and the holder holding section 10. The coating removal section 22 has an optical fiber mounting section 24 on which the optical fiber F is mounted, and a lid section 25 which can be opened and closed with respect to the optical fiber mounting section 24. The lid section 25 is closed on the optical fiber mounting section 24 by moving in a first direction D1. The lid section 25 is opened from the optical fiber mounting section 24 by moving in a second direction D2.

[0022] The coating removal unit 22 has a hinge 26 that allows the lid unit 25 to be opened and closed relative to the optical fiber mounting unit 24. The hinge 26 extends along the extending direction A at an end of the main body 20 opposite the third direction D3. The lid unit 25 rotates about the hinge 26, allowing the lid unit 25 to be opened and closed relative to the optical fiber mounting unit 24. The main body 20 holds the optical fiber F mounted on the optical fiber mounting unit 24 by sandwiching it between the optical fiber mounting unit 24 and the lid unit 25.

[0023] For example, the optical fiber mounting part 24 has a side surface part 24d facing the third direction D3 and a top surface part 24c facing the lid part 25 to be closed. The optical fiber mounting part 24 has a first blade 27 that cuts into the coating of the optical fiber core F. The first blade 27 is disposed on the front side of the optical fiber mounting part 24. The first blade 27 has, for example, a first blade part 27b that cuts into the coating and a support part 27c that supports the first blade part 27b. The first blade part 27b and the support part 27c are made of, for example, metal. The first blade part 27b and the support part 27c are integrally formed.

[0024] For example, the lid 25 has a side surface 25b facing the third direction D3 when closed, a top surface 25c facing the second direction D2 when closed, and an inner surface 25d facing the top surface 24c of the optical fiber mounting part 24 when closed. The lid 25 has a second blade 28 that cuts into the coating of the optical fiber core F. The second blade 28 is disposed on the front side of the lid 25. The second blade 28 is disposed at a position facing the first blade 27 along the first direction D1 when the lid 25 is closed on the optical fiber mounting part 24. The second blade 28 has a second blade 28b that cuts into the coating and a support part 28c that supports the second blade 28b. The second blade 28b and the support part 28c are made of, for example, metal. The second blade 28b and the support part 28c are integrally formed.

[0025] The first blade 27 and the second blade 28 face each other along the first direction D1 when the lid portion 25 is closed on the optical fiber mounting portion 24. This causes an incision to be made in the coating of the optical fiber F located between the first blade portion 27b and the second blade portion 28b. The distance between the first blade portion 27b and the second blade portion 28b is set so that the first blade portion 27b and the second blade portion 28b come into contact with the coating of the optical fiber F, but the first blade portion 27b and the second blade portion 28b do not come into contact with the glass fiber of the optical fiber F.

[0026] The optical fiber mounting portion 24 has a heater 29. The heater 29 is disposed behind the first blade 27. For example, the heater 29 constitutes the mounting surface 24b of the optical fiber mounting portion 24 on which the optical fiber core F is mounted. The heater 29 receives power and heats the coating of the optical fiber core F. The power supply to the heater 29 is controlled by a heater current switch (not shown) that is turned on when the lid portion 25 is closed on the optical fiber mounting portion 24 and turned off when the lid portion 25 is opened from the optical fiber mounting portion 24. The heater 29 performs heating when the lid portion 25 is closed on the optical fiber mounting portion 24.

[0027] The operation unit 23 is disposed behind the coating removal unit 22. The operation unit 23 has a switch 23b for turning the power on and off or adjusting the temperature of the heater 29, and a display unit 23c for indicating the state of the heater 29 (e.g., the heating temperature and on / off state of the heater 29). The display unit 23c indicates, for example, that the optical fiber F is heated by the heater 29 and that the temperature of the optical fiber F has reached the maximum temperature for coating removal. For example, the operation unit 23 has a built-in battery (not shown) for supplying power to the heater 29.

[0028] When the coating of the optical fiber F is removed using the coating remover 1, the optical fiber F is placed on the heater 29 of the optical fiber placement unit 24 (the placement surface 24b). The removal of the coating of the optical fiber F may be performed in a dark place, and in a dark place, it may happen that the optical fiber F placed on the optical fiber placement unit 24 is not easily visible. When removing the coating from a plurality of optical fiber F such as an intermittent tape, the plurality of optical fiber F may need to be aligned so that the plurality of optical fiber F is aligned along the third direction D3. The coating remover 1 according to this embodiment has a light diffusion unit 30 to enhance the visibility of the optical fiber F placed on the placement surface 24b. The light diffusion unit 30 will be described in detail below.

[0029] Fig. 4 is a cross-sectional view of the light diffusion unit 30 taken along a plane extending in both the extension direction A and the first direction D1. As shown in Figs. 3 and 4, the light diffusion unit 30 is provided on a wall unit 40 aligned with the optical fiber mounting unit 24 along the extension direction A. For example, the wall unit 40 has a wall surface 41 facing the lid unit 25 of the operation unit 23. The wall surface 41 extends along the first direction D1 and the third direction D3.

[0030] The light diffusion section 30 is disposed in a hole 42 recessed in the wall section 40 in a direction away from the optical fiber placement section 24 (for example, backward). The hole 42 penetrates the wall section 40 in the extension direction A, for example. The hole 42 has an upper surface 42b extending from the wall surface 41 along the extension direction A and extending in both the extension direction A and the third direction D3, and a pair of inner side surfaces 42c extending in both the first direction D1 and the extension direction A and facing each other along the third direction D3. Furthermore, the hole 42 has a lower surface 42d extending obliquely upward from the wall surface 41 and extending along the third direction D3, and an extending surface 42f extending from an end of the lower surface 42d opposite to the wall surface 41 along the extension direction A. The hole 42 is defined by the upper surface 42b, the pair of inner side surfaces 42c, the lower surface 42d, and the extending surface 42f.

[0031] For example, the sheath remover 1 includes a substrate 50 built into the operation unit 23. The substrate 50 is equipped with an element for processing an electrical signal for controlling each part of the sheath remover 1 in response to an operation on the operation unit 23. The substrate 50 is equipped with a light source 51. For example, the light source 51 is mounted on the upper surface 50b of the substrate 50. For example, the light source 51 is an LED light source that emits LED light. The operation unit 23 has, for example, a light-on switch 23d for turning on and off the light of the light diffusion unit 30. As an example, the light-on switch 23d is a tactile switch. For example, when the light-on switch 23d is turned on, an element of the substrate 50 outputs a control signal to the light source 51. At this time, the light source 51 emits light in response to the control signal and irradiates the light diffusion unit 30 with light L1. As an example, the light L1 is a straight light.

[0032] For example, the light diffusion section 30 is made of acrylic or polycarbonate. As an example, the light diffusion section 30 contains diffusion particles that diffuse the light L1. The light diffusion section 30 converts the light L1 from the light source 51 into diffused light L2, and irradiates the diffused light L2 onto the optical fiber core F mounted on the optical fiber mounting section 24. The light diffusion section 30 irradiates the diffused light L2 obliquely downward toward the mounting surface 24b of the optical fiber mounting section 24. That is, the optical axis of the diffused light L2 extends obliquely downward from the light diffusion section 30 toward the mounting surface 24b.

[0033] For example, the optical axis of the diffused light L2 extends forward (to a location closer to the holder holding unit 10) than the center of the extension direction A of the placement surface 24b. In this case, the portion of the placement surface 24b closer to the holder holding unit 10 can be brightened. As an example, the color of the diffused light L2 is milky white. For example, the light diffusion unit 30 is fixed to the upper surface 42b and in contact with the extending surface 42f. For example, the light diffusion unit 30 is in close contact with the upper surface 42b and the extending surface 42f. In this case, the intrusion of water or the like into the hole 42 can be suppressed. As an example, the light diffusion unit 30 is fixed to the hole 42 via an adhesive member 33. The adhesive member 33 is, for example, a double-sided tape. When the light diffusion unit 30 is inserted into the hole 42, the lower surface 42d extends obliquely downward as it moves away from the light diffusion unit 30.

[0034] FIG. 5 is a perspective view showing the light diffusion unit 30 and the substrate 50. As shown in FIG. 4 and FIG. 5, the light diffusion unit 30 has a first protruding portion 31 protruding in a direction away from the optical fiber placement portion 24 and a second protruding portion 32 protruding downward. The first protruding portion 31 and the second protruding portion 32 each enter into a hole 42. The first protruding portion 31 has an upper surface 31b on which the adhesive member 33 is placed, an end surface 31c extending in both the first direction D1 and the third direction D3 at an end of the first protruding portion 31 in the extending direction A, and a lower surface 31d facing the opposite side to the upper surface 31b. The lower surface 31d faces the light source 51. That is, the light source 51 is provided below the lower surface 31d. The second protrusion 32 has a first surface 32b facing the inner surface 43 of the wall portion 40, an end surface 32c extending in both the extension direction A and the third direction D3 at the lower end of the first surface 32b, and a second surface 32d facing opposite to the first surface 32b.

[0035] The substrate 50 has a recess 52 recessed in a direction away from the optical fiber mounting portion 24 (for example, backward). A part of the light diffusion portion 30 fits into the recess 52. For example, the light diffusion portion 30 has a step portion 34 placed on the upper surface 50b of the substrate 50. The step portion 34 has a first step surface 34b extending downward from the lower surface 31d of the first protrusion 31, and a second step surface 34c extending from the lower end of the first step surface 34b in both a direction approaching the optical fiber mounting portion 24 (for example, forward) and in the third direction D3. The first step surface 34b faces the light source 51 along the extension direction A. The first step surface 34b is a light incidence surface into which the light L1 is incident from the light source 51. For example, the direction in which the optical axis of the light L1 extends coincides with the extension direction A. For example, the light diffusion unit 30 is fixed to the substrate 50 in a state in which the light diffusion unit 30 fits into the recess 52 and the second step surface 34c is placed on the upper surface 50b of the substrate 50.

[0036] FIG. 6 is a front view of the light diffusion unit 30 when the light diffusion unit 30 is viewed along the extension direction A. FIG. 7 is a rear view of the light diffusion unit 30. As shown in FIG. 5, FIG. 6, and FIG. 7, the light diffusion unit 30 has a T-shape when viewed along the extension direction A. For example, the light diffusion unit 30 has an upper surface portion 36 including a first protrusion 31, a side surface portion 37 including a second protrusion 32, and a light exit portion 38 that emits diffused light L2. The upper surface portion 36 extends in both the extension direction A and the third direction D3 and has a plate shape having a thickness in the first direction D1. The side surface portion 37 extends downward from an end of the upper surface portion 36 in a direction approaching the optical fiber placement portion 24. The side surface portion 37 extends in both the first direction D1 and the third direction D3 and has a plate shape having a thickness in the extension direction A.

[0037] The light exit portion 38 protrudes from the top surface portion 36 and the side surface portion 37 in a direction approaching the optical fiber mounting portion 24. The light exit portion 38 has an inclined surface 39 that extends along the third direction D3 and is inclined with respect to the first direction D1 so as to move downward away from the optical fiber mounting portion 24. The inclined surface 39 is a light exit surface from which the diffused light L2 is emitted. The light L1 that is incident on the light diffusion portion 30 from the first step surface 34b along the extension direction A is converted into diffused light L2 inside the light diffusion portion 30, and the diffused light L2 is emitted obliquely downward from the inclined surface 39 (see FIG. 4). As an example, the inclined surface 39 has a rectangular shape.

[0038] For example, the light emitting portion 38 has an upper surface 38b extending from the upper surface portion 36 to the upper end of the inclined surface 39, a lower surface 38c extending from the side surface portion 37 to the lower end of the inclined surface 39, and a pair of side surfaces 38d connecting the upper surface 38b and the lower surface 38c to each other. For example, the upper surface 38b and the lower surface 38c have a rectangular shape. The pair of side surfaces 38d are aligned along the third direction D3. For example, the side surfaces 38d have a trapezoidal shape that narrows downward.

[0039] Next, the effects of the sheath remover 1 according to this embodiment will be described. The sheath remover 1 has an optical fiber mounting section 24 and a lid section 25. The optical fiber mounting section 24 has a first blade 27 for cutting the sheath, and the lid section 25 has a second blade 28 facing the first blade 27. The optical fiber mounting section 24 has a mounting surface 24b on which the coated optical fiber F is mounted. The sheath remover 1 has a light diffusion section 30 that irradiates the optical fiber F mounted on the mounting surface 24b of the optical fiber mounting section 24 with diffused light L2. When the light diffusion section 30 irradiates the optical fiber F with diffused light L2, the optical fiber F can be irradiated with light more uniformly than light with strong linearity such as light from an LED. Therefore, the visibility of the optical fiber F mounted on the mounting surface 24b can be improved. The light diffusion section 30 irradiates the diffused light L2 obliquely downward toward the mounting surface 24b of the optical fiber mounting section 24. When the diffused light L2 is irradiated diagonally downward toward the mounting surface 24b, the visibility of the optical fiber core F placed on the mounting surface 24b can be improved compared to when the diffused light L2 is irradiated horizontally.

[0040] As described above, the light diffusion portion 30 may be provided on the wall portion 40 aligned with the optical fiber mounting portion 24 along the extending direction A, which is the direction in which the optical fiber core F mounted on the optical fiber mounting portion 24 extends. The light diffusion portion 30 may be disposed in a hole 42 recessed in the wall portion 40 in a direction away from the optical fiber mounting portion 24. In this case, since the light diffusion portion 30 is disposed in the hole 42 formed in the wall portion 40, it is possible to suppress the intrusion of water or the like into the light diffusion portion 30. Therefore, it is possible to protect the light diffusion portion 30 from moisture or the like.

[0041] As described above, the light diffusion portion 30 may have the first protrusion 31 protruding in a direction away from the optical fiber mounting portion 24 and the second protrusion 32 protruding downward, and each of the first protrusion 31 and the second protrusion 32 may fit into the hole 42. In this case, since each of the first protrusion 31 and the second protrusion 32 in the light diffusion portion 30 fits into the hole 42 of the wall portion 40, the light diffusion portion 30 can be firmly fixed to the wall portion 40.

[0042] As described above, the hole 42 may have a lower surface 42d extending below the light diffusion section 30, and the lower surface 42d may extend obliquely downward as it becomes more distant from the light diffusion section 30. In this case, even if water droplets or the like enter the hole 42, the water droplets or the like flow obliquely downward along the lower surface 42d so as to be away from the light diffusion section 30, and then exit the hole 42. Therefore, the light diffusion section 30 can be protected from water droplets or the like.

[0043] The above describes the embodiment of the sheath remover according to the present disclosure. However, the present invention is not limited to the above embodiment. That is, it is easily understood by those skilled in the art that the present invention can be modified and changed in various ways within the scope of the gist of the claims. For example, the shape, size, number, material and arrangement of each part of the sheath remover can be appropriately changed within the scope of the gist of the above.
