Description

Technical Field

[0001] The present invention relates to a tape dispenser capable of dispensing a tape. Background Art

[0002] Conventionally, there has been known a tape dispenser configured to dispense a tape accommodated inside through an opening to the outside by rotating a part of a main body (for example, see Patent Document 1).

[0003] However, in the conventional tape dispenser, it is not possible to provide a shutter that can close the opening when not in use. Therefore, there is a possibility that the tape may be accidentally dispensed from the opening when not in use, and the tape may accidentally adhere to surrounding objects.

[0041] Hereinafter, an embodiment of the present invention will be described with reference to Figures 1 to 12 In this embodiment, the present invention is applied to the following tape dispenser configured to be able to accommodate a tape d1 with relatively low shape retention such as a masking tape or a transparent tape therein and discharge the tape d1 to the outside.

[0042]

[0043] ​The tape dispenser includes: a first member A that holds a replacement member D, which is a tape core d2 around which a tape d1 is wound; a second member B that can perform a relative movement with respect to the first member A, that is, can rotate relative to the first member A; an opening / closing member 3 that is supported so as to be able to slide relative to the first member A between a closed position (E) where an opening G provided in the first member A can be closed and an open position (F) where the opening G provided in the first member A can be opened; a tape pulling-out portion C that discharges and rewinds the tape d1 relative to the outside by causing the second member B to rotate relative to the first member A; and an opening / closing member linkage mechanism R that causes the opening / closing member 3 to move between the closed position (E) where the opening G can be closed and the open position (F) where the opening G can be opened in linkage with the movement of the second member B.

[0044] The tape dispenser includes: a first member A having an opening G through which the tape d1 can be led out from the inside to the outside; and a second member B that can rotate relative to the first member A. Further, the tape dispenser, by a relative movement in a first direction between the first member A and the second member B, that is, by causing the second member B to rotate forward relative to the first member A, the tape d1 is discharged to the outside and the opening / closing member 3 that closes the opening G can be driven in a direction to open the opening G. Moreover, by a relative movement in a second direction between the first member A and the second member B, that is, by causing the second member B to rotate backward relative to the first member A, the tape d1 is wound back to the inside and the opening / closing member 3 that closes the opening G can be driven in a direction to close the opening G.

[0045] Hereinafter, each structure of the tape dispenser will be described in detail.

[0046] <<First member A>>

[0047] The first member A has a cylindrical outer shape. More specifically, the first member A has an outer shape in which both sides of a substantially cylindrical peripheral surface are closed by circular side surfaces. On the outer surface side of a side plate a1 in a base 1, which is one side surface of the first member A, a disk-shaped second member B that forms an operation portion that a user can directly rotate and operate and has substantially the same diameter as the first member A is attached. An opening G for discharging the tape d1 accommodated inside the first member A to the outside is provided in the peripheral surface of the first member A.

[0048] The first member A includes a base 1 that holds the replacement member D and a cover 2 that is detachably attached to the base 1. The replacement member D is a member in which a tape d1 is wound around a tape core d2.

[0049] <Replacement member D>

[0050] The replacement part D includes a core d2 and a belt d1 wound around the core d2. In other words, the core d2 constitutes the replacement part D in a state where the belt d1 is wound around it.

[0051] The belt d1 is a member with a known structure wound around the outer peripheral surface of the cylindrical part d3 in the core d2, and is a belt-shaped member provided with an adhesive layer (not shown) on one side.

[0052] The core d2 includes a cylindrical part d3 through which a core shaft a3 erected on the base 1 is inserted, and a substantially annular side wall part d4 extending in a flange shape from both edge parts of the cylindrical part d3. The left and right side wall parts d4 are arranged in a substantially parallel manner.

[0053] In addition, the replacement part D of the present embodiment is configured to be connectable to other replacement parts of the same shape via a connecting part d5. More specifically, the connecting parts d5 are respectively provided on the left and right side wall parts d4 in the core d2. On one side wall part d4, connecting convex parts d5(a) serving as engaging parts protruding outward are provided at two positions, and on the other side wall part d4, connecting holes d5(b) serving as engaging parts capable of connecting the connecting convex parts d5(a) of other cores of the same shape are provided at six positions.

[0054] The core d2 is set such that the number of arranged connecting holes d5(b) in a circular hole shape is larger than the number of arranged connecting convex parts d5(a) in a cylindrical shape. Thereby, it is easy for the user to engage the connecting convex part d5(a) in one core d2 with the connecting hole d5(b) in other cores d2 of the same shape.

[0055] <Base 1>

[0056] The base 1 includes a core shaft a3 that holds the core d2 rotatably. The axis of the core shaft a3 erected substantially perpendicular to the side plate a1 of the base 1 is arranged at a position offset from the relative rotation center of the first member A and the second member B, that is, at a position inconsistent with the connecting hole a2 of the first member A and the connecting shaft b1 of the second member B. In the present embodiment, the core shaft a3 is erected at a position farther from the opening G than the connecting hole a2.

[0057] A connecting hole a2 is penetrated through the center part of the base 1. The connecting hole a2 engages with a connecting shaft b1 provided at the center part of the second member B. That is, it is configured such that the connecting hole a2 of the base 1 provided in the first member A engages with the connecting shaft b1 of the second member B, and relative rotation can be performed in a state where the second member B is connected to the first member A.

[0058] The base body 1 includes a circular side plate a1 and a mandrel a3 that protrudes from a position offset from the center of the side plate a1, that is, from the inner surface of the side plate a1 offset from the relative rotation center of the first member A and the second member B.

[0059] The base body 1 includes: a pair of cover engaging pieces a4 that form a part of the peripheral surface protruding from the peripheral edge of the side plate a1; a pay-out roller holding hole a5 that is formed through the vicinity of the peripheral edge of the side plate a1 where the opening G is formed and can hold one end of the pay-out roller 4 rotatably; a pressing member support shaft a6 that protrudes from the vicinity of the peripheral edge of the side plate a1 where the opening G is formed and can support a pressing member 5 that can press the pay-out roller 4 rotatably; and a posture holding engaging portion a7 in a cantilever shape that is provided at a position adjacent to the pressing member support shaft a6 and elastically biases the pressing member 5 in the direction of the leaving posture (K) away from the pay-out roller 4 by engaging with an engaging piece 53 provided at the base end portion of the pressing member 5.

[0060] In addition, although the pressing member 5 is always biased in the direction of the leaving posture (K) by the posture holding engaging portion a7, by attaching the cover 2 to the base body 1, the cover 2 can overcome the elastic force of the cantilever beam-shaped posture holding engaging portion a7 and bias the pay-out roller 4 in the pressing posture (J). More specifically, a posture holding portion 22e that can press the pressing member 5 in the pressing posture (J) direction is provided on the cover 2.

[0061] The base body 1 includes: a winding prevention roller holding hole a8 that is formed through a position closer to the peripheral edge of the side plate a1 than the pay-out roller holding hole a5 and can hold one end of the winding prevention roller 6 rotatably; and a second gear support shaft a9 that protrudes from a position adjacent to the pay-out roller holding hole a5 and the winding prevention roller holding hole a8 and can support a second gear m2 that meshes with a first gear m1 provided on the second member B rotatably.

[0062] In addition, the base body 1 includes a roller pressing member S that is attached to the side plate a1 and can support one ends of the pay-out roller 4 and the winding prevention roller 6 rotatably. A guide groove (not shown) for engaging with a guide projection 33a of a rear plate portion 33 of the opening / closing member 3 is provided on the outer edge of the roller pressing member S.

[0063] On the side plate a1 of the base body 1, there are provided a relay member support shaft a15 capable of supporting the relay member r1 constituting the opening / closing member linkage mechanism R so as to be rotatable, and a link member support shaft a16 capable of supporting the link member r2 constituting the opening / closing member linkage mechanism R so as to be rotatable. The relay member r1 can mesh with the first gear m1 and can mesh with the meshing teeth r21 of the relay member provided on the link member r2. The link member r2 can mesh with the relay member r1 and can engage with the opening / closing member 3.

[0064] On the side plate a1 of the base body 1, there is provided an elastically deformable cantilever-shaped rotation restricting engagement portion a13 capable of engaging with the engagement protrusion r11 provided on the relay member r1 and capable of restricting the rotation of the relay member r1 to a predetermined position. As will be described later, the rotation restricting engagement portion a13 constitutes the driving force transmission restricting portion Q in the opening / closing member linkage mechanism R.

[0065] <Cover 2>

[0066] The cover 2 is detachably attached to the base body 1. A knife H for cutting the tape d1 is attached to the cover 2 with the cutting edge facing the opening G. The cover 2 includes a disk-shaped side wall 21 and a peripheral wall 22 that integrally extends from the peripheral edge portion of the side wall 21 and constitutes a main part of the peripheral surface in the first member A.

[0067] On the inner surface side of the side wall 21, there are protruding: a first auxiliary protrusion 21a that engages with the cylindrical portion d3 of the tape core d2 supported by the mandrel a3 and can assist the posture of the tape core d2; and a second auxiliary protrusion 21b that engages with the base end portion of the pressing member 5, that is, the pivoting portion of the pressing member 5 that pivots about the pressing member support shaft a6, and can assist the posture of the pressing member 5.

[0068] The peripheral wall 22 includes: an opening notch portion 22a that forms the opening G; a knife holding portion 22b that is provided at a position adjacent to the opening notch portion 22a and can hold the knife H for cutting the tape d1; a fitting notch portion 22c that can be fitted with a part of the cover engaging portion a4 provided on the base body 1; and an engaging hole 22d that is provided between the fitting notch portion 22c and the side wall 21 and engages with the engaging protrusion a41 provided at the top end of the cover engaging portion a4.

[0069] At a position closer to the center portion than the knife holding portion 22b, there is provided a sheet-like posture holding portion 22e capable of holding the pressing member 5 in the pressing posture (J). By pressing the pressing member 5 in the direction of the pressing posture (J), the posture holding portion 22e can restrict the pressing member 5 from rotating from the pressing posture (J) in the direction of the separating posture (K).

[0070] <<Opening and closing member 3>>

[0071] The opening and closing member 3 can close and open the opening G of the first member A in linkage with the rotation of the second member B. The opening and closing member 3 is located between the side plate a1 constituting the base 1 and the roller pressing member S, and is supported so as to be able to slide relative to the base 1. The opening and closing member 3 is configured to be movable along the circumferential surface of the first member A between a closed position (E) where the opening G of the first member A can be closed and an open position (F) where the opening G of the first member A can be opened and the belt d1 can be discharged to the outside.

[0072] The opening and closing member 3 includes: a front plate portion 31 which is in the shape of a plate curved so as to protrude outward and forms a circumferential surface that is always exposed to the outside of the first member A at the closed position (E) and the open position (F); a rear plate portion 33 which is continuously provided with the front plate portion 31 via a step portion 32; and a link portion 34 which integrally extends in a cantilever shape from the rear end portion of the rear plate portion 33 toward the inside.

[0073] The rear plate portion 33 is also in the shape of a plate curved so as to protrude outward and is provided at a position offset toward the central portion of the first member A with respect to the front plate portion 31. The rear plate portion 33 can close the opening G at the closed position (E) and retract to the inner surface side of the peripheral wall 22 at the open position (F).

[0074] On the rear plate portion 33, guide protrusions 33a protruding outward are formed at the left and right outer side portions. The left and right guide protrusions 33a are engaged with a guide groove a12 provided on the side plate a1 and a guide groove (not shown) provided on the roller pressing member S.

[0075] The opening and closing member 3 can stably move on the track between the closed position (E) and the open position (F) by the engagement of the left and right guide protrusions 33a with the guide groove a12. At the end edge of the rear wall portion 33 on the side of the side plate a1, a locking claw engaging portion 33b that engages with a locking claw a11 in a cantilever shape provided on the side plate a1 at the open position (F) is protrudingly provided. By the engagement of the locking claw engaging portion 33b protrudingly provided on the opening and closing member 3 with the locking claw a11 of the side plate a1 at the open position (F), the opening and closing member 3 is configured to be able to be stable at the open position (F).

[0076] The link portion 34 constitutes an opening and closing member linkage mechanism R. In the link portion 34, a groove-shaped link member engaging recess 34a serving as an engaged portion into which a engaging convex portion r22 serving as an engaging portion provided on the link member r2 can be engaged is formed.

[0077] The opening and closing tool 3 can be changed from the closed position (E) to the open position (F) in conjunction with the release operation of the belt d1 by rotating the second member B in the positive direction. In addition, the opening and closing tool 3 can be changed from the open position (F) to the closed position (E) by reversing the second member B.

[0078] <<Second member B>>

[0079] The second member B is attached to the first member A so as to be relatively rotatable with respect to the first member A. The second member B constitutes an operation portion that is gripped and rotated when the user unwinds the belt d1.

[0080] The second member B is attached to one side of the first member A so as to be relatively rotatable relative to the first member A. The second member B is a disc-shaped member having substantially the same diameter as the first member A. A connecting shaft b1 is formed at the center of the second member B to engage with a connecting hole a2 provided in the base 1 of the first member A.

[0081] The second member B includes a second member body b2 having a disc shape and having a finger hook portion b21 formed on the outer edge for preventing fingers from slipping, and a first gear m1 integrally provided on the inner surface side of the second member body b2 with the axis aligned therewith.

[0082] The first gear m1 is located on the outer surface side of the side plate a1. The first gear m1 meshes with the second gear m2 (constituting the belt pull-out portion C) pivotally supported on the side plate a1 of the first member A and meshes with the relay member r1 (constituting the opening and closing member linkage mechanism R) pivotally supported on the side plate a1 of the first member A. In addition, in the relay member r1, a plurality of first gear meshing teeth r12 meshing with the first gear m1 are arranged in a partial arc shape along the rotation center thereof.

[0083] The inner surface of the second member body b2, i.e., the back side of the hooking portion b21, is provided with a plurality of locking recesses b22 along the circumferential direction. The recesses b22 can be locked with the locking portion a14 cantilevered near the outer periphery of the side plate a1 of the base 1.

[0084] <<Belt pull-out section C>>

[0085] The tape pull-out portion C is linked to the relative rotation of the second member B with respect to the first member A, and the tape d1 is clamped and pulled out from the tape core d2 and sent out to the outside. In other words, the tape dispenser is provided with a tape pull-out portion C that is linked to the relative rotation of the second member B with respect to the first member A, and the tape d1 is clamped and pulled out from the tape core d2 and sent out to the outside.

[0086] The tape pulling-out part C is provided on the first member A. That is, the tape pulling-out part C includes: a pay-off roller 4 that can rotate in the direction of paying out the tape d1 along with the relative rotation of the second member B with respect to the first member A in the forward rotation direction; a pressing member 5 that presses the tape d1 disposed on the pay-off roller 4 toward the pay-off roller 4 side and can press the tape d1 between it and the pay-off roller 4; and a winding prevention roller 6 that is disposed outside the pay-off roller 4 and can rotate in the same direction as the pay-off roller 4.

[0087] <Pay-off roller 4>

[0088] The pay-off roller 4 includes: a base part 41 having a cylindrical shape; a third gear m3 that is integrally provided with the base part 41 at an end on the side of the side plate a1 and meshes with the second gear m2 as a gear disposed on the base body 1; and a plurality of ring members 43 that are disposed at intervals on the outer peripheral surface of the base part 41. The ring members 43 are members made of a flexible synthetic resin. The pay-off roller 4 is connected to the second member B via a gear train and can rotate in linkage with the rotation of the second member B. That is, the pay-off roller 4 can pay out the tape d1 to the outside in linkage with the forward rotation action of the second member B and can wind the tape d1 back to the inside in linkage with the reverse rotation action of the second member B.

[0089] In addition, as Figure 12 shown, the portion (the base part 41 and the ring members 43) of the pay-off roller 4 that engages with the tape d1 is configured as a whole to have a shape in which the central part in the left-right direction is recessed in the axial direction compared to the left and right end parts.

[0090] <Pressing member 5>

[0091] The pressing member 5 includes: a plate-shaped pressing member main body 51 whose base end part is supported by a pressing member support shaft a6; a pressing roller 52 that is rotatably supported at the top end part of the pressing member main body 51 and directly presses the tape d1 interposed therebetween toward the pay-off roller 4 side; and an engaging piece 53 that protrudes from the base end part of the pressing member main body 51 in a direction opposite to the extending direction of the pressing member main body 51. The pressing member 5 takes a pressing posture (J) in which it can press the pay-off roller 4 in a state where the cover 2 is installed, and in a state where the cover 2 is detached from the base body 1 (a state where a replacement part D can be installed), it can take a leaving posture (K) of moving away from the pay-off roller 4 by using the elastic acting force of the posture holding engaging part a7 provided on the base body 1.

[0092] In addition, as Figure 12As shown, the portion of the pressing roller 52 that engages with the belt d1 is configured as a whole to have a shape (barrel shape) in which the central portion in the left - right direction bulges outward more than the left - right end portions.

[0093] As described above, the portion of the pay - out roller 4 that engages with the belt d1 has a concave shape along the pressing roller 52 having a barrel shape. Therefore, the belt d1 can be bent and clamped through the cooperation of the pay - out roller 4 and the pressing roller 52, and the straight - running performance of the belt d1 can be stabilized.

[0094] In addition, the overall shape (barrel shape) of the portion of the pressing roller 52 that engages with the belt d1 and the overall shape (concave shape along the barrel shape) of the portion of the pay - out roller 4 that engages with the belt d1 can of course be reversed.

[0095] <Anti - entanglement roller 6>

[0096] The anti - entanglement roller 6 includes: a base 61 having a cylindrical shape; a fourth gear m4 which is a gear integrally provided at an end portion on the side of the side plate a1 of the base 61 and meshes with the second gear m2 disposed on the base body 1; and a plurality of belt guiding portions 63 which protrude in a flange shape on the outer peripheral surface of the base 61 and the peripheral end edges of which can abut against the belt d1. On the peripheral end edges of the belt guiding portions 63, fine acute - angled protrusions 63a are arranged in such a way that the belt d1 is difficult to adhere to. The anti - entanglement roller 6 is connected to the second member B via a gear train and can rotate in linkage with the rotation of the second member B. That is, the anti - entanglement roller 6 rotates in linkage with the forward rotation action of the second member B to perform a rotation that can release the belt d1 outward and rotates in linkage with the reverse rotation action of the second member B to perform a rotation that can wind the belt d1 inward.

[0097] <<Opening - closing member linkage mechanism R>>

[0098] The opening - closing member linkage mechanism R includes: a first gear m1 provided on the second member B; a relay member r1 rotatably supported by the first member A and having a first gear engaging tooth r12 that meshes with the first gear m of the second member B; a link member r2 rotatably supported by the first member A and having a relay member engaging tooth r21 at the base end portion that meshes with the link member engaging tooth r13 provided on the relay member r1 and having a cylindrical engaging convex portion r22 as an engaging portion that engages with the opening - closing member 3 at the tip end portion; and an opening - closing member 3 that is supported by the first member A so as to be slidably movable between a closed position (E) and an open position (F) and has a link member engaging concave portion 34a as an engaged portion that can be engaged with the engaging convex portion r22 of the link member r2.

[0099] Furthermore, the opening / closing member linkage mechanism R is provided with a driving force transmission restricting portion Q, which is disposed between the first gear m1 and the link member r2 and can restrict the transmission of the driving force in the forward rotation direction as the first direction by the first gear m1 to the opening / closing member 3 in the open position (F).

[0100] <Relay member r1>

[0101] The relay member r1 is rotatably supported by a relay member support shaft a15 provided on the base 1. The relay member r1 includes: a first gear engaging tooth r12, which is provided with a plurality of teeth in a partial arc shape along the relay member support shaft a15 and can engage with the first gear m1; a link member engaging tooth r13, which is provided with a plurality of teeth in a partial arc shape along the relay member support shaft a15 and can engage with a relay member engaging tooth r21 arranged in a partial arc shape at the base end portion of the link member r2; and an engaging protrusion r11, which extends outward and can engage with a rotation restricting engaging portion a13 provided on the base body 1 at a predetermined position.

[0102] <Link member r2>

[0103] In the link member r2, the base end portion is rotatably supported by a link member support shaft a16 provided on the base 1, and the tip end portion extends toward the opening / closing member 3 and engages with the opening / closing member 3. The link member r2 includes: a relay member engaging tooth r21, which is provided with a plurality of teeth in a partial arc shape along the link member support shaft a16 at the base end portion and can engage with the link member engaging tooth r13 of the relay member r1; and an engaging convex portion r22 as an engaging portion, which protrudes from the tip end portion and can engage with a link member engaging concave portion 33b of a link portion 34 provided on the opening / closing member 3.

[0104] <Driving force transmission restricting portion Q>

[0105] The driving force transmission restricting portion Q is mainly composed of the relay member r1 and the rotation restricting engaging portion a13. The relay member r1 has a plurality of teeth arranged in a partial arc shape that can engage with the first gear m1, i.e., the first gear engaging teeth r12. The rotation restricting engaging portion a13 engages with the engaging protrusion r11 provided on the relay member r1 and restricts the rotation of the relay member r1 at a predetermined position.

[0106] That is, as Figure 8As shown, when the relay member r1 rotates under the driving force generated by the forward rotation of the first gear m1, at a predetermined stage, i.e., when the opening / closing member 3 reaches the open position (F), the engaging projection r11 of the relay member r1 abuts against the rotation-limiting engaging portion a13 having a cantilever shape. After that, even if the relay member r1 is driven by the driving force in the forward rotation direction from the first gear m1 and attempts to rotate, the rotation-limiting engaging portion a13 having a cantilever shape will elastically deform, and the first gear engaging teeth r12 of the relay member r1 and the first gear m1 will no longer engage and are arranged in a partially circular arc shape (refer to Figure 8 the part of the reference numeral V in the attached drawing). That is, if the driving force transmission restricting portion Q acts, the driving force in the forward rotation direction will not be transmitted to the relay member r1, the link member r2, and the opening / closing member 3 through the first gear m1.

[0107] At this time, the meshing relationship between the second member B having the first gear m1 and the relay member r1 is released, so the forward rotation operation can continue. Therefore, if the second member B is rotated forward, the belt d1 can continue to be paid out. That is, the first gear m1 of the second member B is properly engaged with the driving force transmission system of the belt pulling portion C for paying out the belt d1, so if the second member B is rotated forward, the belt d1 can continue to be paid out.

[0108] In addition, while the relay member r1 avoids the transmission of the driving force from the first gear m1 by using the rotation-limiting engaging portion a13, it maintains a predetermined posture. Therefore, when the second member B is reversely operated, the first gear engaging teeth r12 in the first gear m1 and the relay member r1 can be properly engaged, and the opening / closing member 3 can be moved from the open position (F) to the closed position (E).

[0109] Next, the operation of the belt dispenser will be described.

[0110] First, a replacement member D, i.e., a belt core d2 wound with the belt d1, is installed on the base 1 of the first member A. As Figures 3 to 5 shown, the engaging piece 53 of the clamping member 5 is urged by the posture-holding engaging portion a7. Therefore, in the state where the cover 2 is detached from the base 1, the clamping member 5 is held in a posture (K) that is easy to install the belt d1.

[0111] Next, the tip of the belt d1 supported by the base 1 is pulled outwards by a finger by a certain dimension, and the pulled-out portion of the belt d1 is brought into contact with the pay-out roller 4.

[0112] After that, by installing the cover 2 on the base 1, the clamping member 5 in the posture (K) is pressed by the posture-holding portion 22e provided on the cover 2 and changed to the pressing posture (J). Thus, a part of the pulled-out belt d1 is clamped by the pay-out roller 4 and the clamping member 5.

[0113] Through the above operations, the preparatory work before use is completed.

[0114] Next, the operation of the discharge belt d1 and the movement of the opening / closing member 3 will be described.

[0115] When the second member B rotates in the positive direction relative to the first member A, the second gear m2 meshing with the first gear m1 integrated with the second member B rotates. The discharge roller 4 having a third gear m3 meshing with the second gear m2 and the anti-entrainment roller 6 having a fourth gear m4 meshing with the second gear m2 rotate in the positive direction in linkage with the rotation of the second member B.

[0116] The belt d1 clamped by the discharge roller 4 and the clamping member 5 is pulled out to the outside in linkage with the rotation of the driven discharge roller 4. In addition, even when the belt d1 droops, the anti-entrainment roller 6 is guided by the belt guide portion 63 rotating in the positive direction in an appropriate direction, i.e., the opening G direction, to suppress the situation where the belt d1 is entrained inward.

[0117] In addition, when the second member B rotates in the positive direction relative to the first member A, the relay member r1 meshing with the first gear m1 also rotates. The relay member r1 constitutes an opening / closing member linkage mechanism R capable of performing an opening / closing operation of the opening / closing member 3 in linkage with the rotation operation of the second member B. That is, the opening / closing member linkage mechanism R also operates in linkage with the belt pulling-out portion C.

[0118] When the second member B rotates in the positive direction relative to the first member A, the driving force is transmitted to the opening / closing member 3 via the first gear m1, the relay member r1, and the link member r2, and the opening / closing member 3 is linked from the closed position (E) toward the open position (F). That is, when the relay member r1 rotates in the positive direction, the link member r2 also rotates in the positive direction in linkage, and the engaging convex portion r22 provided on the link member r2 presses the link member engaging concave portion 34a formed on the link portion 34 of the opening / closing member 3 while moving the opening / closing member 3 from the closed position (E) to the open position (F) through the cam action of the engaging convex portion r22 and the link member engaging concave portion r22.

[0119] After that, when the opening / closing member 3 reaches the open position (F), the stepped portion 32 engages with the opening notch portion 22a of the peripheral wall 22 to prohibit further movement of the opening / closing member 3. At this time, due to the action of the driving force transmission restricting portion Q provided in the opening / closing member linkage mechanism R, a positive driving force is not applied to the opening / closing member 3 that has reached the open position (F).

[0120] That is, even if the user rotates the second member B further in the positive direction after the opening and closing member 3 moves to the open position (F), the driving force transmission limiting unit Q works and the first gear m1 and the first gear meshing teeth r12 provided on the relay member r1 are no longer properly meshed (see Figure 8 ), so the first gear m1 idles relative to the relay member r1.

[0121] Next, when the second member B is rotated in the opposite direction relative to the first member A, the driving force is transmitted to the opening and closing member 3 via the first gear m1, the relay member r1 and the link member r2, and the opening and closing member 3 is linked from the open position (F) to the closed position (E). That is, the relay member r1 is also engaged with the first gear m1 and rotates in the opposite direction, and the link member r2 is also linked to rotate in the opposite direction, and the engaging convex portion r22 provided on the link member r2 presses the link member engaging concave portion 34a formed on the link portion 34 of the opening and closing member 3, and the opening and closing member 3 is moved from the open position (F) to the closed position (E) by the cam action of the engaging convex portion r22 and the link member engaging concave portion r22.

[0122] Furthermore, when the second member B is rotated in the reverse direction relative to the first member A, the tape puller C also operates together with the shutter interlocking mechanism R, thereby pulling the leading end of the tape d1 located near the opening G back toward the inside.

[0123] When the opening and closing member 3 reaches the closed position (E), the power transmission system of the opening and closing member linkage mechanism R including the first gear m1 is locked, and thus the reverse rotation operation of the second member B is also locked.

[0124] As described above, the tape dispenser of the present embodiment includes: a first member A that holds the tape d1 and includes an opening G that can lead the tape d1 from the inside to the outside; and a second member B that can perform a relative motion, that is, a rotational motion, relative to the first member A. Furthermore, the tape d1 is released by the relative rotational motion of the first member A and the second member B in the first direction, and the opening and closing member 3 that closes the opening G can be driven in a direction to open the opening G.

[0125] Therefore, in the tape dispenser of the present embodiment, the opening G for releasing the tape d1 can be appropriately opened and closed by the opening and closing member 3. In other words, when the second member B is rotated forward relative to the first member A, the opening and closing member 3 can be moved in the direction of opening the opening G and the end of the tape d1 stored inside can be led out to the outside through the opening G. Therefore, when not in use, the opening and closing member 3 can be used to appropriately protect the tape d1 and when in use, the opening and closing member 3 can be opened while releasing the tape d1, and the automatic opening and closing function is appropriately performed, which is excellent in convenience of use.

[0126] In the tape dispenser, by the relative movement of the first member A and the second member B in the second direction, the tape d1 is rewound, and the opening / closing member 3 for closing the opening G can be driven in the direction of closing the opening G.

[0127] Therefore, in the tape dispenser of the present embodiment, the opening G for discharging the tape d1 can be appropriately opened and closed by the opening / closing member 3. In other words, when the second member B is reversed relative to the first member A, the opening / closing member 3 can move in the direction of closing the opening G, and the end of the tape d1 accommodated inside can be introduced into the inside from the vicinity of the opening G. Therefore, when not in use, the tape d1 can be appropriately protected by the opening / closing member 3, and when the opening / closing member 3 is closed, the end of the tape d1 retracts inward and it is difficult to touch the opening / closing member 3. That is, even when changing to the non-use state, the automatic opening / closing function of closing the opening / closing member 3 while rewinding the tape d1 can be appropriately exerted, and the usability is excellent.

[0128] The first member A includes a base body 1 for holding the tape d1 and a cover 2 detachably provided on the base body 1. Therefore, by detaching and attaching the cover 2, the tape d1 can be held on the base body 1.

[0129] An opening / closing member linkage mechanism R is provided that causes the opening / closing member 3 to move between a closed position (E) where the opening G can be closed and an open position (F) where the opening G can be opened in linkage with the rotational movement of the second member B.

[0130] Therefore, the opening / closing operation of the opening / closing member 3 can be linked with the second member B that also functions as an operation unit for discharging the tape d1, so the operability is excellent.

[0131] The opening / closing member linkage mechanism R includes: a first gear m1 provided on the second member B; a link member r2 rotatably supported by the first member A and having a plurality of teeth, i.e., relay member engagement teeth r21, at the base end that can be indirectly engaged with the first gear m1 via a relay member r1, and a engagement convex portion r22 as an engagement portion that engages with the opening / closing member 3 at the tip end; and the opening / closing member 3 supported so as to be slidable relative to the first member A and having a link member engagement concave portion 34a as an engaged portion that can be engaged with the engagement convex portion r22 of the link member r2.

[0132] Therefore, by engaging the link portion 34 provided on the opening / closing member 3 with the link member r2 pivotally supported by the first member A, the opening / closing operation of the opening / closing member 3 is appropriately achieved.

[0133] The opening / closing member linkage mechanism R is provided with a driving force transmission restricting portion Q, which is disposed between the first gear m1 and the link member r2 and can restrict the transmission of the driving force in the forward rotation direction as the first direction by the first gear m1 to the opening / closing member 3 located at the open position (F).

[0134] Therefore, after the opening / closing member 3 is moved to the open position (F) by the action of the opening / closing member linkage mechanism R, the driving force generated by the forward rotation of the second member B is not transmitted to the opening / closing member 3. Thus, the opening / closing member 3 can be properly located at the open position (F) and can continue to perform the operation of discharging the tape d1 by the tape discharging portion C.

[0135] In addition, the present invention is not limited to the embodiments described in detail above.

[0136] The type of the tape can be applied to various types and is not limited to the tape with low conformability.

[0137] The relative movement between the first member and the second member is not limited to the rotational movement and can also be a linear movement.

[0138] Of course, the specific structures of the first member and the second member can also be variously changed within the scope not departing from the gist of the present invention.

[0139] The structure of the opening / closing member linkage mechanism can be any structure as long as it is a structure linked to the movement of the second member. For example, a power transmission system for converting the rotation of the second member into the opening / closing movement of the opening / closing member can apply various power transmission systems such as a mechanism using a gear train and a transmission belt.

[0140] For example, the link member of the opening / closing member linkage mechanism may not be connected to the first gear via a relay member, or may be a member in which the link member directly meshes with the first gear.

[0141] The specific structure of the driving force transmission restricting portion is of course not limited to the structure shown in the above embodiments. For example, the power transmission restricting portion may also be a member that can restrict the transmission of the driving force in the reverse rotation direction by the first gear to the opening / closing member located at the closed position.

[0142] The tape discharging portion only needs to be a member that discharges the tape outward by relatively rotating the second member with respect to the first member, and is not limited to the member shown in the above embodiments. For example, the gear train for transmitting the rotation of the second member to the rotation of the discharging roller can be variously set. In addition, it can also be configured to transmit the rotation of the second member to the discharging roller and the anti-entanglement roller via a transmission belt.

[0143] In addition, regarding the specific structures of each part, it is not limited to the above embodiments and can be variously deformed within the scope not departing from the gist of the present invention.
