Description

Technical Field

[0001] This invention relates to a rewinder (with a rewinder, Japanese: ) ). Background Technology

[0002] Previously, the following device was disclosed: by passing the manufactured product (Japanese: The shielding tape is rewound onto the narrow-diameter core, thus enabling the production of smaller tapes that are subdivided into rollers.

[0003] According to the device, by making a small strip from the finished product's covering strip, one can use their favorite pattern in both their own home and office or give it to others.

[0004] However, conventional devices suffer from drawbacks such as a complicated setting process for rewinding the masking tape of the finished product onto the narrow-diameter core, which makes the operation difficult for the user.

[0005] That is, in conventional devices, it is necessary to first remove one and the other shaft members from the main body of the device, then install the finished product's shielding strip onto the shaft member removed from the main body, and install the small-diameter belt core onto the other shaft member removed from the main body. Furthermore, after installing the finished product's shielding strip and the small-diameter belt core onto one and the other shaft members, a forced reassembly of these shaft members onto the main body is performed.

[0006] Furthermore, the above situations are not limited to shielding strips; the same applies to other strips as well. Summary of the Invention

[0054] The following is for reference Figures 1-24 This invention describes one embodiment.

[0055] This embodiment applies the invention to a tape rewinder capable of rewinding tape tp (primarily shielding tape). The tape rewinder rewinds the tape tp relative to a tape core E by attaching the top of the tape tp pulled from a commercially available tape body T to the tape core E and rotating the tape core E using a handle 5. Furthermore, as illustrated in the example, the tape body T is generally formed by winding a tape tp with an adhesive surface on one side and various colors or patterns on the other side around a core material sn having a hollow portion; however, it can also be a so-called coreless type tape without a core material sn.

[0056] The rewinder rewinds the belt tp pulled from the finished belt body T onto the belt core E, which has a cylindrical portion e1 with a diameter smaller than that of the core material sn of the belt body T. This allows for the production of smaller, roller-shaped belt bodies M. In other words, by using the rewinder of this embodiment, the user can use the belt tp pulled from the finished belt body T as... Figure 3 The new subdivided band M is created as shown.

[0057] The tape rewinder comprises: a tape rewinder body A, the tape rewinder body A having a support body 1, a tape support portion 2 serving as a driven shaft, a tape core support portion 4 serving as a drive shaft, and a handle 5 serving as an operating portion, the tape support portion 2 being able to support a tape body T pivotally supported on the support body 1 and wound with tape tp, the tape core support portion 4 being able to support a tape core E for winding tape tp pulled out from the tape body T, and the handle 5 causing the tape core support portion 4 and the tape core E to rotate together; and a cover B, the cover B being supported to rotate between an open position (F) in which the tape body T and the tape core E can be installed or removed relative to the tape rewinder body A and a closed position (G) in which the tape body T and the tape core E cannot be disengaged relative to the tape rewinder body A.

[0058] A loosening suppression unit C is provided in the rewinder. The loosening suppression unit C suppresses the loosening of the cover B relative to the rewinder body A in the closed posture (G) by elastically engaging the rewinder body A with the cover B.

[0059] The rewinder includes a spacer member 3 that is detachable from the belt support portion 2. Furthermore, the rewinder is equipped with a rotary support mechanism D for the belt body T, which can be selected as follows: Figures 1-3 , Figures 18-20 As shown, the belt body T is supported on the belt support portion 2 where the spacer member 3 is installed, and as shown... Figure 21 As shown, the belt body T is directly supported on the belt support 2, where the spacer member 3 has been detached from the belt support 2.

[0060] The following is a detailed description of the various structures of the rewinder.

[0063] <Support 1>

[0064] The support body 1 includes: a bottom wall 11 extending horizontally along a tabletop or other mounting surface; an upright wall 12 erected from the right end edge of the bottom wall 11; a front wall 13 serving as a first extension plate extending inward from the front end edge of the upright wall 12 toward the cover B; a rear wall 14 serving as the first extension plate extending inward from the rear end edge of the upright wall 12; a cover engaging portion 15 protruding inward from the upright wall 12; and a hub 16 protruding inward from the upright wall 12 and capable of supporting the belt support 2 for rotation.

[0065] The bottom wall 11 is a plate-shaped component, which appears as a long rectangular strip in the front-to-back direction when viewed from below. The bottom wall 11 is integrally connected to the lower ends of the upright wall 12, the front wall 13, and the rear wall 14.

[0066] The upright wall 12 is generally rectangular in shape when viewed from the side. A cylindrical hub 16 is integrally formed and protrudes from the upper front portion of the upright wall 12. A shaft hole 12a is provided in the upper rear portion of the upright wall 12 for the main shaft portion 43 of the belt core support portion 4 to pass through. A rectangular cylindrical cover engaging portion 15 is integrally formed and protrudes from the lower rear portion of the upright wall 12. Figure 15 As shown, a plurality of ratchet teeth r2 are formed around the shaft hole 12a on the inner surface side of the upright wall 12 to form a ratchet mechanism R in a manner that surrounds the shaft hole 12a.

[0067] The front wall 13 forms the first extension plate of the loosening suppression unit C. The front wall 13 is a plate-shaped member integrally and continuously provided with the bottom wall 11 and the upright wall 12. The front wall 13 is generally rectangular when viewed from the front. On the upper part of the inner surface side of the front wall 13, a first pressing protrusion c1 extending in the left-right direction and convex rearward as an abutment portion is provided. On the left part of the front wall 13 that is the part on the cover B side, a shaft hole 13a is provided that can support the shaft 63a protruding from the front wall 63 of the cover B so that it can rotate.

[0068] The rear wall 14 forms the first extension plate of the loosening suppression unit C. The rear wall 14 is a plate-shaped member integrally and continuously provided with the bottom wall 11 and the upright wall 12. The rear wall 14 is generally rectangular in shape when viewed from the rear. On the upper part of the inner surface side of the rear wall 14, a second pressing protrusion c2 extending in the left-right direction and convex in the forward direction is provided as an abutment part. On the left part of the rear wall 14 that is the part on the cover B side, a shaft hole 14a is provided that can support the shaft 64a protruding from the rear wall 64 of the cover B so that it can rotate.

[0069] The cover engaging portion 15 can engage with the cover B. The cover engaging portion 15 is integrally provided from the upright wall 12 toward the cover B. At the top end of the cover engaging portion 15, a rectangular engaging hole 15a is provided, which extends through in the vertical direction. The engaging hole 15a constitutes a locking mechanism L that locks the cover B relative to the main body A of the rewinder in a closed position (G). The locking claw 72, which is a locking part provided in the locking member 7 of the cover B, can elastically engage with the engaging hole 15a.

[0070] The hub 16 is inserted into the cylindrical portion 21 of the belt support portion 2 to support the belt support portion 2 so that it can rotate. At the top end of the hub 16, there is a locking claw 16a that engages with the stepped portion 21a of the belt support portion 2 as a locking portion to prevent the belt support portion 2 from falling off.

[0071] <Belt Support Part 2>

[0072] The belt support 2 can support the belt T, which is a finished product, directly or indirectly via the spacer member 3. The belt support 2 can be rotatably supported by the hub 16, which protrudes horizontally from the upright wall 12.

[0073] The belt support portion 2 has a cylindrical portion 21 and a flange portion 22 extending from one end of the cylindrical portion 21.

[0074] The cylindrical portion 21 is supported by a hub 16 of a support body 1 inserted into its hollow portion. A stepped portion 21a, serving as an engagement portion, is formed on the inner circumferential surface of the cylindrical portion 21, allowing engagement with the engagement claws 16a of the hub 16. At the base end of the cylindrical portion 21, a through hole 21b, also serving as an engagement portion, is provided, allowing engagement with the elastic claws 31a provided on the spacer member 3. At the top end of the cylindrical portion 21, a positioning recess 21c is provided, allowing engagement with the positioning protrusion 31b provided on the spacer member 3.

[0075] Multiple protrusions 21d are provided on the outer peripheral surface of the cylindrical portion 21. The multiple protrusions 21d can abut against the inner peripheral surface of the core material sn in the installed belt body T.

[0076] The flange portion 22 is a plate-shaped component that is approximately annular when viewed from the side. The flange portion 22 extends outward from the base end of the cylindrical portion 21. The extension dimension of the flange portion 22 extending from the cylindrical portion 21 is set to be larger than the thickness dimension of the spacer member 3 installed on the cylindrical portion 21.

[0077] <Spacing Member 3>

[0078] The spacer member 3 is installed in a manner that allows it to be attached to and detached from the belt support portion 2. The spacer member 3 can support the belt T while it is mounted on the belt support portion 2. Furthermore, if the diameter of the hollow portion in the belt T is smaller than the diameter of the spacer member 3, the spacer member 3 can be removed from the belt support portion 2, and the belt T can be directly supported on the belt support portion 2.

[0079] like Figure 22 and Figure 23 As shown, the spacer member 3 has an inner peripheral wall 31 that engages with the cylindrical portion 21 of the belt support portion 2, an outer peripheral wall 32 that engages with the inner peripheral surface of the core material sn of the belt T, and a connecting wall 33 that connects the inner peripheral wall 31 and the outer peripheral wall 32.

[0080] The inner peripheral wall 31 is cylindrical with a through hole into which the cylindrical portion 21 of the belt support 2 is inserted. A pair of elastic claws 31a are provided on the inner peripheral wall 31, capable of engaging with a pair of through holes 21b provided in the cylindrical portion 21 of the belt support 2. Furthermore, the spacer member 3 has a pair of recesses 34 formed mainly by the inner peripheral wall 31 and the connecting wall 33, recessed in the axial direction. And, elastic claws 31a are provided on the inner peripheral wall 31 forming the bottom of the recesses 34.

[0081] Furthermore, a positioning protrusion 31b is formed at one end of the inner peripheral wall 31, protruding in the axial direction. Multiple protrusions 31b are provided, that is, they are spaced apart in four locations in the circumferential direction, each protruding in the axial direction. By engaging the protrusions 31b at the four locations with the recesses 21c provided in the cylindrical portion 21 of the belt support portion 2, the spacer member 3 is positioned relative to the belt support portion 2.

[0082] Near the recess 34 on the outer surface of the outer peripheral wall 32, a plurality of outwardly protruding protrusions 32a are provided. The plurality of protrusions 32a can abut against the inner peripheral surface of the core material sn in the belt body T being installed.

[0083] <Core Support Part 4>

[0084] The core support 4 supports the core E in a detachable manner.

[0085] Here, the core E is wound around the strip tp drawn from the finished strip body T. The core E has a cylindrical portion e1 located at the center and extending in the left-right direction, and two side plates e2 located at the left and right ends of the cylindrical portion e1 and arranged in pairs. On one of the side plates e2 of the core E, namely the right side plate, a pair of engaging protrusions t1 are provided. The pair of engaging protrusions t1 are located symmetrically with respect to the axis of the cylindrical portion e1 and can engage with a pair of engaging holes 42a provided in the core support portion 4.

[0086] The core support portion 4 includes: a core support shaft 41, which is inserted into the cylindrical portion e1 of the core E; a flange portion 42, which is disposed at the base end of the core support shaft 41 and whose inner surface side can be spliced ​​to the right side plate e2 of the core E; a cylindrical main shaft portion 43, which is disposed on the outer surface side of the flange portion 42 and protrudes from the flange portion 42 toward the upright wall 12; and a pair of ratchet pawls r1, which are disposed near the base end of the main shaft portion 43.

[0087] The core support shaft 41 is a cylindrical component that is configured to be able to be inserted into the shaft hole e11 of the cylindrical part e1 provided in the core E.

[0088] The flange portion 42 is a circular plate-shaped component, with the base end of the core support shaft 41 connected to its inner surface and the base end of the main shaft portion 43 connected to its outer surface. The flange portion 42 is provided with engagement holes 42a, which engage with engagement protrusions t1 of the right-side side plate e2 located in the core E. In other words, the core E is inserted into the core support shaft 41 through the shaft hole e11, and the pair of engagement protrusions t1 of the right-side side plate e2 engage with the pair of engagement holes 42a in the flange portion 42, thereby enabling it to rotate integrally with the core support portion 4 and the handle 5.

[0089] The main shaft 43 is a cylindrical component with a diameter larger than that of the core support shaft 41. The main shaft 43 is supported so that it can rotate relative to the shaft hole 12a provided in the upright wall 12 of the support body 1. The main shaft 43 is connected to the connecting part 51a provided at the base end of the handle 5 in a manner that aligns the shaft center.

[0090] like Figure 15 As shown, the ratchet pawl r1 includes a ratchet arm r11 that extends cantilevered from the main shaft portion 43 and is configured to be elastically deformable, and a pawl portion r12 provided at the top of the ratchet arm r11. The ratchet pawl r1 can engage with the ratchet teeth r2 provided on the support body 1. In other words, the ratchet pawl r1 and the ratchet teeth r2 cooperate to form a ratchet mechanism R that allows only the forward rotation of the core support portion 4 and the handle 5.

[0091] <Controller 5>

[0092] The handle 5 includes: a handle body 51, which has a connecting portion 51a at its base end that is connected to the main shaft portion 43 of the core support portion 4 and rotates integrally with the core support portion 4; and a clamping member 52, which is supported on the top end of the handle body 51 in a manner that allows it to rotate relative to the handle body 51.

[0093] The handle body 51 includes: a connecting portion 51a, which is formed at the base end and connected to the core support portion 4 through the shaft hole 12a of the support body 1; an arm portion 51b, which extends outward from the base end; and a clamping support shaft 51c, which protrudes from the top end of the arm portion 51b and is used to support the clamping member 52 so that it can rotate. A pair of engaging claws t2 are provided in the connecting portion 51a. By engaging these pair of engaging claws t2 with the claw engaging portion 42b formed in the flange portion 42 of the core support portion 4, the handle body 51 is connected to the core support portion 4.

[0094] <Ratchet Mechanism R>

[0095] like Figure 15 As shown, the ratchet mechanism R is used to rotate the handle 5 in only one direction, namely the forward direction. The ratchet mechanism R is disposed between the support body 1 and the core support part 4. The ratchet mechanism R has ratchet teeth r2 disposed on the upright wall 12 of the support body 1, and a pair of ratchet pawls r1 that are cantilevered on the main shaft part 43 of the core support part 4 and can engage with the ratchet teeth r2.

[0096] When the handle 5 is to be rotated forward, the pawl r12 of the ratchet pawl r1 is shaped to pass over the ratchet tooth r2 and the ratchet arm r11 can be elastically deformed, thus allowing the handle 5 to rotate forward. On the other hand, when the handle 5 is to be rotated backward, the pawl r12 of the ratchet pawl r1 is firmly engaged in a manner that prevents it from passing over the ratchet tooth r2, thus preventing the handle 5 from rotating backward.

[0097] <<Cover B>>

[0098] Cover B is supported so as to be able to rotate relative to the tape rewinder body A between an open position (F) and a closed position (G). Cover B is capable of adopting an open position (F) in which the tape body T and tape core E can be installed or removed relative to the tape rewinder body A, and a closed position (G) in which the tape body T and tape core E cannot be detached relative to the tape rewinder body A. In other words, cover B can cover one side of the tape body T and tape core E from the outside in a manner that prevents the tape body T and tape core E installed on the tape rewinder body A from detaching.

[0099] Cover B comprises: a cover body 6; a locking member 7, which is supported to slide between an upper position (J) and a lower position (K) relative to the cover body 6; a first splicing plate 8, which is supported to rotate relative to the cover body 6 and to splice with a side of the belt body T directly supported on the belt body support 2 or indirectly supported on the side of the belt body T via a spacer member 3 in a closed position (G); and a second splicing plate 9, which is supported to rotate relative to the cover body 6 and to splice with the outer surface of the left side plate e2 of the belt core E supported on the belt core support 4 in a closed position (G).

[0100] <Main Body 6>

[0101] The cover body 6 comprises: a bottom wall 61; a standing wall 62, which is erected on the left end edge of the bottom wall 61; a front wall 63, which extends inward from the front end edge of the standing wall 62, i.e., towards the rewinder body A; and a rear wall 64, which extends inward from the rear end edge of the standing wall 62.

[0102] The bottom wall 61 of the cover is integrally connected to the lower ends of the upright wall 62, the front wall 63, and the rear wall 64 of the cover. In addition, the left and right width dimension of the bottom wall 61 is set to be shorter than the left and right width dimension of the bottom wall 11 in the support body 1.

[0103] The cover support wall 62 is positioned approximately orthogonal to the support wall 12 of the support body 1 in the open position (F) and approximately parallel to the support wall 12 of the support body 1 in the closed position (G). A first splicing plate support shaft 62a for supporting the first splicing plate 8 in a rotatable manner is provided on the upper inner surface of the front portion of the cover support wall 62. A second splicing plate support shaft 62b for supporting the second splicing plate 9 in a rotatable manner is provided on the upper inner surface of the rear portion of the cover support wall 62. A locking member support portion H for supporting the locking member 7 in a vertically movable manner is provided in the lower rear portion of the cover support wall 62.

[0104] The first and second splicing plate support shafts 62a and 62b are equipped with anti-detachment claws t3 and t4 to prevent the first and second splicing plates 8 and 9 from falling off.

[0105] The locking member support portion H is recessed from the outside to the inside of the raised wall 62, forming a receiving space sp that can accommodate the locking member 7 in a way that allows it to move up and down. The locking member support portion H includes: a peripheral wall portion h1, which has a front peripheral wall h11 covering the front side of the locking member 7, a lower peripheral wall h12 covering the lower side of the locking member 7, and a rear peripheral wall h13 covering the rear side of the locking member 7; and an inner wall portion h2, which connects the inner ends of the peripheral wall portion h1.

[0106] The front peripheral wall h11 and the rear peripheral wall h13 in the peripheral wall portion h1 have an upper engaging groove m1 and a lower engaging groove m2 extending in the left-right direction, respectively. The engaging protrusion 71a, which is provided at the front end and the rear end of the locking member 7 and is elastically deformable, can selectively engage with the upper and lower engaging grooves m1 and m2, and the locking member 7 is held in the upper position (J) and the lower position (K).

[0107] The locking member support portion H has a connecting hole h3 formed above the inner wall portion h2, which connects the outer surface side and the inner surface side of the cover body 6. Through the connecting hole h3, the locking claw 72 of the locking member 7 can engage with the engaging hole 15a of the cover engaging portion 15 provided on the upright wall 12 of the support body 1.

[0108] The front wall 63 forms the second extension plate of the loosening suppression unit C. The front wall 63 is a plate-shaped component that is integrally and continuously provided with the bottom wall 61 and the upright wall 62 of the cover. When viewed from the front, the front wall 63 has a fan shape formed in a circular shape at the upper right corner.

[0109] On the upper part of the outer surface side of the front wall 63 of the cover, a first pressing groove c3 is formed, which extends in the left-right direction and is pressed against by a first pressing protrusion c1 provided on the front wall 13 of the support body when the cover B is in the closed position (G). Near the cover standing wall 62 in the lower part of the front wall 63 of the cover, a shaft 63a is provided and supported in the shaft hole 13a provided in the support body 1.

[0110] The rear wall 64 forms the second extension plate of the loosening suppression unit C. The rear wall 64 is a plate-shaped component integrally and continuously provided with the bottom wall 61 and the upright wall 62 of the cover. The upper left corner of the rear wall 64 is formed in a circular shape when viewed from the rear.

[0111] On the upper part of the outer surface side of the rear wall 64 of the cover, a second pressing groove c4 is formed, which extends in the left-right direction and is pressed against by the second pressing protrusion c2 provided on the rear wall 14 of the support body when the cover B is in the closed position (G). Near the cover standing wall 62 in the lower part of the rear wall 64 of the cover, a shaft 64a is provided and supported in the shaft hole 14a provided in the support body 1.

[0112] <Locking Component 7>

[0113] The locking member 7 is supported so that it can move up and down relative to the cover body 6 between an upper position (J) and a lower position (K). The locking member 7 engages with the cover engagement portion 15 in the upper position (J), thereby locking the cover B in a closed position (G). The locking member 7 is configured not to engage with the cover engagement portion 15 in the lower position (K).

[0114] The locking member 7 includes: a locking member body 71, which is a generally rectangular box shape with its inner surface open and has a groove mz for finger anti-slip on its exposed outer surface, i.e., the left outer side; and a locking claw 72, which protrudes upward from the inner edge of the locking member body 71 and can engage with the engaging hole 15a of the cover engaging part 15 at the upper position (J).

[0115] At the front and rear ends of the locking member 7, there are engaging protrusions 71a that can selectively and elastically engage with the upper and lower engaging grooves m1 and m2 in the locking member support H.

[0116] The locking claw 72 extends upward from the upper inner end of the locking member body 71 and has a claw member 72a that is supported in a cantilever shape. In the closed position (G) of the cover body 6, when the locking member 7 is in the upper position (J), the engaging protrusion 71 of the locking member body 71 engages with the engaging groove m1 on the upper side of the locking member support portion H, and the claw member 72a of the locking claw 72 engages with the engaging hole 15a of the cover engaging portion 15.

[0117] In other words, the rewinder is equipped with a locking mechanism L that can lock the cover B relative to the rewinder body A in a closed position (G). Furthermore, the locking mechanism L is mainly composed of a cover engaging portion 15 provided on the rewinder body A and a locking member 7 that is movable relative to the cover B between an upper position (J) and a lower position (K) and can engage with the cover engaging portion 15 at the upper position (J).

[0118] The first splicing plate 8 is a ring-shaped component when viewed from the side. The first splicing plate 8 has a central hole 81 that engages with the first splicing plate support shaft 62a, which is erected on the cover support wall 62. Furthermore, the anti-detachment claw t3 provided on the first splicing plate support shaft 62a can engage with the hole 81.

[0119] The second splicing plate 9 is a ring-shaped component when viewed from the side. The second splicing plate 9 has a central hole 91 that engages with the second splicing plate support shaft 62b, which is erected on the cover support wall 62. Furthermore, an anti-disengagement claw t4 provided on the second splicing plate support shaft 62b can engage with the hole 91.

[0120] <<Loosening Inhibition Unit C>>

[0121] A loosening suppression unit C is provided in the rewinder. The loosening suppression unit C suppresses the loosening of the cover B relative to the rewinder body A in the closed posture (G) by elastically engaging the rewinder body A with the cover B.

[0122] The loosening suppression unit C includes: a front wall 13 and a rear wall 14 serving as a first extension plate, the front wall 13 and the rear wall 14 being disposed on the main body A with a rewinder; a front wall 63 and a rear wall 64 serving as a second extension plate, the front wall 63 and the rear wall 64 being disposed on the cover B; and first and second pressing protrusions c1 and c2, which are convex and serve as abutment portions, the first and second pressing protrusions c1 and c2 being disposed on the front wall 13 and the rear wall 14 of the main body A with a rewinder and capable of elastically abutting against the front wall 63 and the rear wall 64. In this embodiment, the front wall 63 and the rear wall 64 are provided with first and second pressing grooves c3 and c4. Furthermore, when the cover B is in a closed position (G), the first and second pressing protrusions c1 and c2 are positioned in the first and second pressing grooves c3 and c4 and are capable of pressing the first and second pressing grooves c3 and c4.

[0123] <<Rotary Support Mechanism D with Body T>>

[0124] The rotating support mechanism D of the belt body T is used to flexibly support belt bodies T of various sizes. In this embodiment, the rotating support mechanism D of the belt body T is provided with a spacer member 3 that can be attached to and detached relative to the belt support portion 2, and is configured to allow for selection such as... Figure 20 As shown, the belt body T is supported on the belt support portion 2 where the spacer member 3 is installed, and as shown... Figure 21 As shown, the belt body T is supported on the belt support 2, where the spacer member 3 has been detached from the belt support 2.

[0125] Furthermore, since the tape body T circulating in the market comes in various sizes, the tape body T used in the tape rewinder of this embodiment may also be a component that is not tightly fitted to the outer periphery of the spacer member 3 or the outer periphery of the cylindrical portion 21 in the tape support portion 2.

[0126] As explained above, the tape rewinder of this embodiment includes a tape rewinder body A. The tape rewinder body A has a tape support portion 2 serving as a driven shaft, a tape core support portion 4 serving as a drive shaft, and a handle 5 serving as an operating portion. The tape support portion 2 can support a tape body T wound with tape tp, and the tape core support portion 4 can support a tape core E for winding tape tp pulled from the tape body T. The handle 5 causes the tape core support portion 4, which serves as a drive shaft, to rotate together with the tape core E. Furthermore, the tape rewinder includes a cover B supported so that it can rotate relative to the tape rewinder body A between an open position (F) and a closed position (G).

[0127] Therefore, a rewinder is provided that can at least properly perform the setting for winding the tape tp pulled from the tape body T onto the tape core E.

[0128] In other words, the cover B is configured to rotate between an open position (F) and a closed position (G) relative to the main body A of the belt rewinder. Therefore, by making the cover B in the open position (F), it is possible to easily install or remove the belt body T and belt core E relative to the main body A of the belt rewinder.

[0129] The main body A of the rewinder is provided with a cover engaging portion 15 that can engage with cover B. Cover B also includes a cover body 6 and a locking member 7 supported so as to slide relative to the cover body 6. By engaging the locking member 7 with the cover engaging portion 15, cover B is locked in a closed position (G).

[0130] Therefore, by simply sliding the locking member 7, the cover B is locked in a closed position (G) relative to the rewinder body A.

[0131] The cover latch 15 protrudes from the upright wall 12 provided on the main body A with the rewinder towards the cover B.

[0132] Therefore, the cover B can be engaged at the middle position of the rewinder body A, so the cover B in the closed position (G) is properly supported on the rewinder body A.

[0133] A loosening suppression unit C is provided, which suppresses the loosening of the cover B relative to the tape rewinder body A by elastically engaging the tape rewinder body A with the cover B.

[0134] Therefore, it is possible to appropriately suppress minor loosening of the cover B relative to the main body A of the rewinder. In other words, by providing the loosening suppression unit C, it is possible to appropriately suppress any discomfort that may occur to the user in the event of minor loosening of the cover B.

[0135] The loosening suppression unit C includes a front wall 13 and a rear wall 14, which are provided on the main body A with a rewinder as first extension plates, a front wall 63 and a rear wall 64, which are provided on the cover B as second extension plates, and first and second pressing protrusions c1 and c2, which are provided on the front wall 13 and the rear wall 14 and can elastically abut against the front wall 63 and the rear wall 64 as abutment portions.

[0136] Therefore, when the cover B is in the closed position (G), the first and second pressing protrusions c1 and c2 disposed on the main body A of the rewinder always press the front wall 63 and the rear wall 64 of the cover, so as to appropriately suppress the loosening of the main body A of the rewinder and the cover B.

[0137] The first and second pressing protrusions, c1 and c2, are designed to be convex, so that loosening can be suppressed using a simple structure.

[0138] The main body A with the rewinder is provided with a ratchet mechanism R that causes the handle 5, which serves as the operating part, to rotate only in one direction, namely the forward direction.

[0139] Therefore, the reverse rotation of the handle 5 can be appropriately suppressed, so the tape tp pulled out from the tape body T is less likely to be irregularly wound relative to the tape core E, and user misoperation can also be suppressed.

[0140] Furthermore, the present invention is not limited to the embodiments described in detail above.

[0141] The tape body is not limited to a tape body made of shielding tape; it can also be a tape body made of other tapes.

[0142] As long as the driven shaft can directly or indirectly support the belt, various structures can be applied.

[0143] The drive shaft only needs to support the belt core directly or indirectly, and various structures can be used. For example, the drive shaft may not be connected to the operating handle.

[0144] The cover only needs to be supported so that it can rotate relative to the main body of the rewinder between an open and closed position, and its shape can be set to an appropriate shape.

[0145] The loosening suppression unit can be achieved simply by making the main body of the rewinder and the cover always elastically engaged, and can adopt an appropriate form within the scope of its purpose.

[0146] For example, there may be only one first extension plate on the main body of the rewinder and one second extension plate on the cover.

[0147] The abutment portion can be provided on either the first or the second extension plate. For example, the pressing protrusion serving as the abutment portion can also be provided on the front wall or the rear wall of the cover.

[0148] In addition, the part that the convex abutment part elastically abuts can be a flat part or not a groove-shaped part.

[0149] Furthermore, the specific structure of each part is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention.
