[0010] Patent Document 2: Japanese Patent Application Publication No. 2018-150160 Summary of the invention

[0011] Problem that the invention aims to solve

[0012] However, in the conventional tape cutter in which the sliding portion 130 reciprocates, since the holding or pulling action for cutting the tape is switched according to the moving direction of the sliding portion 130, it is difficult for an inexperienced user to understand the operation method. From the perspective of the universal design required recently, there is still room for improvement.

[0013] On the other hand, in the conventional latter type of tape cutter that performs a punching action, although the operation method is clear, since the main body 220 needs to be pressed relative to the cam cover 238 of the cam mechanism 230, the posture during use is limited to only one. In terms of the user being unable to select an easy operating posture, there is still room for improvement from the perspective of universal design.

[0014] The present invention is made to solve the above-mentioned existing technical problems, and its purpose is to provide a tape cutter that has clear and easy-to-understand functions and operation directions of the operation parts, and is easy to operate and use by any user.

[0015] Solutions for solving problems

[0016] (1) To achieve the above-mentioned object, the tape cutter of the present invention comprises: a shell body having a winding body storage portion for storing a winding body of the tape and an opening from which the tape can be fed out; a feeding mechanism portion having a feeding operation member movably supported on the shell body, and causing the tape to be fed out in a feeding direction from the winding body toward the opening according to an operation input to the feeding operation member; and a cutting mechanism portion having a cutting operation member movably supported on the shell body, and causing the front end side of the tape in the feeding direction to be cut near the opening according to an operation input to the cutting operation member. The tape cutter is characterized in that the shell body has a tape delivery cylinder, and the tape delivery cylinder forms a tape delivery passage from the winding body storage part to the opening, and the cutting operation part of the cutting mechanism part is arranged to be able to emerge from the outer wall part of one side of the tape delivered from the opening to the outside of the one side, and the delivery operation part of the delivery mechanism part is arranged to be able to move along the outer wall part of the tape delivery cylinder on the other side of the tape delivered from the opening.

[0017] According to this configuration, in the tape cutter of the present invention, the cutting operation member of the cutting mechanism is arranged to be able to emerge and retract from the outer wall portion on one side of the tape fed out from the opening in the feeding operation member and the tape feeding cylinder, and on the other hand, the feeding operation member of the feeding mechanism can be moved and operated along the outer wall portion on the other side of the tape. Therefore, the cutting operation member and the feeding operation member are respectively arranged on the two sides of the tape fed out from the tape feeding cylinder, and the respective operation directions are clearly different in the direction substantially orthogonal to the approaching outer wall portion or in the direction along the approaching outer wall portion, and the function and operation direction of each operation part are clear and easy to understand, and the user can select a comfortable operation posture.

[0018] (2) In the tape cutter of the present invention, the housing body may have a first placement surface on the side opposite to the tape delivery tube with respect to the winding body storage portion, and when the first placement surface is supported to be substantially horizontal, the housing body can stand in a vertical posture with the tape delivery tube located vertically upward. In this case, the housing body in the first posture with the tape delivery tube located at the upper end side can be held, or the cutting operation member or the delivery operation member can be easily operated with one hand on either side of the tape delivered from the opening at the upper end side.

[0019] (3) In the tape cutter of the present invention, the following configuration may be adopted: when the housing body is in a horizontal position with the cutting operation member of the cutting mechanism located at a vertically lower side, the second placement surface is formed by the cutting operation member and the winding body storage portion, and when the second placement surface is supported to be substantially horizontal, the housing body can be self-supporting with the delivery operation member of the delivery mechanism located at a vertically upper side.

[0044] Hereinafter, a mode for carrying out the present invention will be described with reference to the drawings.

[0045] Figures 1 to 9 The tape cutter 10 of one embodiment of the present invention is configured as a manual cutter that can be held and operated with one hand, and contains a tape roll body R1 (see FIG. 1 ) composed of a tape T1 wound in a roll shape in a detachable manner. Figure 3 , hereinafter referred to as the wound body).

[0046] like Figure 1 as well as Figure 3As shown, the adhesive tape T1 is formed into a roll R1 by winding multiple layers of double-sided adhesive tape with separators on the outer periphery of a cylindrical winding core C1, and one end of the outer periphery of the roll R1 is used as the front end, and can be rolled out (unrolled and sent out) in a manner that the front end is peeled off in the sending direction. In addition, the adhesive tape 1 can also be a single-sided adhesive tape without a separator and having an adhesive layer on one side of the base sheet, or a tape with an adhesive seal carried on a separator at a predetermined interval, etc.

[0047] like Figure 1 to Figure 5A As shown in FIG. 5B , the tape cutter 10 includes a housing body 12 having a substantially constant thickness direction width W in the tape width direction of the tape roll body R1 (see FIG. 5B ). Figure 4A ), a slit-shaped opening 11 is formed on the shell body 12, which serves as a delivery outlet for the tape T1 rolled out from the tape roll body R1.

[0048] Specifically, the shell body 12 is formed by integrally forming a winding body storage portion 13 and a tape delivery cylinder portion 14, wherein the winding body storage portion 13 stores the tape winding body R1 (rolled tape), and the tape delivery cylinder portion 14 forms a tape delivery passage 14a from the outlet 13a of the winding body storage portion 13 to the opening 11.

[0049] In addition, the shell body 12 has a loading and unloading cover portion 21, a concave shell portion 22, and a first fixed cover 23 and a second fixed cover 24, wherein the loading and unloading cover portion 21 can open the winding body storage portion 13 and the tape delivery cylinder portion 14 on a side side (front side) of the tape winding body R1, and the concave shell portion 22 holds the loading and unloading cover portion 21 in a loading and unloading manner, and is formed into a predetermined concave shape corresponding to the winding body storage portion 13 and the tape delivery cylinder portion 14, and the first fixed cover 23 and the second fixed cover 24 are fixed to the concave shell portion 22 in a manner of sandwiching the tape delivery passage 14a in the middle.

[0050] The winding body storage portion 13 has a supporting cylinder portion 13b that supports the core C1 of the tape winding body R1 so that it can rotate, and is formed into a container shape that can store the entire tape winding body R1 in a nearly circular shape so that it can rotate. By removing the loading and unloading cover portion 21 from the concave shell portion 22, the front side can be opened to replace the tape.

[0051] The tape delivery tube 14 protrudes in the delivery direction of the tape T1 from the roll storage section 13 toward the opening 11. Figure 1 , Figure 3In the figure, a delivery mechanism part 15 is provided between the first storage shell part 22c (the outer wall part on the other side) of the concave shell part 22 located on the lower side of the tape delivery passage 14a and the first fixed cover 23 (the outer wall part on the other side). The delivery mechanism part 15 delivers the tape T1 to the outside through the opening 11 according to the delivery operation input.

[0052] Moreover, in Figure 1 , Figure 3 In the figure, a cutting mechanism portion 16 is provided between the second storage shell portion 22d (the outer wall portion on one side) of the concave shell portion 22 located on the upper side of the tape delivery passage 14a and the second fixed cover 24 (the outer wall portion on one side). The cutting mechanism portion 16 cuts the tape T1 delivered to the outside of the tape delivery cylinder 14 near the opening 11.

[0053] More specifically, if Figure 3 as well as Figure 6 As shown, the loading and unloading cover portion 21 includes a transparent cover portion 21a, a peripheral wall portion 21b on one side, a snap-on main fitting portion 21c, a tape guide 21d, and a positioning snap-on portion 21e, wherein the transparent cover portion 21a covers the winding body storage portion 13 and the tape delivery cylinder portion 14 in a manner that the winding body storage portion 13 and the tape delivery cylinder portion 14 can be opened on one side of the tape winding body R1, and the peripheral wall portion 21b on one side is a peripheral wall with a height of about 1 / 2 of the width W in the thickness direction in the peripheral wall section of the winding body storage portion 13 except for the outlet 13a of the open section connected to the tape delivery cylinder portion 14, and the snap-on main fitting portion 21c can be loaded and unloaded and fitted into the concave shell portion 22 corresponding to the winding body storage portion 13. Figure 3 In the right part, the tape guide 21d protrudes at a predetermined position in the concave housing portion 22 corresponding to the tape delivery cylinder 14, and the positioning engaging portion 21e restricts the rotation around the center of the main fitting portion 21c at a specific position.

[0054] The concave shell portion 22 has a cover shell portion 22a, a peripheral wall portion 22b on the other side, a first storage shell portion 22c and a second storage shell portion 22d, and a locking protrusion 22e, wherein the cover shell portion 22a covers the winding body storage portion 13 and the tape delivery cylinder 14 on the other side (back side) of the tape winding body R1, and the peripheral wall portion 22b on the other side becomes a peripheral wall of about 1 / 2 of the width W in the thickness direction in the peripheral wall section of the winding body storage portion 13 outside the open section connected to the tape delivery cylinder 14, the first storage shell portion 22c and the second storage shell portion 22d are integrally connected to the first fixed cover 23 and the second fixed cover 24, and store the delivery mechanism portion 15 and the cutting mechanism portion 16, and the locking protrusion 22e is used to lock the reset spring of the delivery operating component 52 (which will be described later).

[0055] When the tape delivery cylinder 14 of the shell body 12 is positioned and retained by the positioning snap-fit ​​portion 21e of the loading and unloading cover portion 21 between the first fixed cover 23 and the second fixed cover 24 fixed to the concave shell portion 22, a side edge portion of a roughly rectangular slit-shaped opening 11 is formed, and the tape guide 21d is arranged in a fixed position inside the shell body 12.

[0056] like Figure 6 As shown, the delivery mechanism 15 includes: a pair of delivery rollers 51, a delivery operation member 52 with a non-return claw 52e, a pair of endless delivery belts 53, a front end support roller 54, a support member 55, and a torsion coil spring 56 for return (first return spring), wherein the pair of delivery rollers 51 are respectively attached to the adhesive surface side of the tape T1 unwound from the tape winding body R1 side in a releasable manner near the tape guide 21d, and rotate in the delivery direction of the tape T1. The delivery operation member 52 with the non-return claw 52e is supported in a manner rotatable in the delivery direction of the tape T1 relative to the housing body 12. A pair of endless delivery belts 53 are respectively hung on the delivery rollers 51. The front end support roller 54 supports the delivery belt 53 with a predetermined tension together with the delivery roller 51, and delivers the tape T1 to the opening 11 side according to the rotation of the delivery roller 51. The support member 55 supports the front end support roller 54 so as to be rotatable in the feeding direction of the tape T1. The return torsion coil spring 56 (first return spring) urges the feeding operation member 52 in the direction opposite to the feeding operation input of the tape T1 described above.

[0057] The pair of delivery rollers 51 are formed of, for example, a self-lubricating resin and are formed into respective concave shapes open to the opposite surface sides of each other, and have a claw gear 51a with internal teeth on the inner peripheral wall portion thereof, which constitutes a ratchet mechanism together with the non-return claw 52e of the delivery operation member 52. In addition, the pair of delivery rollers 51 are respectively formed with an outer peripheral groove 51b for the delivery tape 53 to be wound around, and the outer peripheral groove 51b contacts the adhesive surface of the adhesive tape T1 in a relatively narrow range in the tape width direction, thereby obtaining the desired tape peeling force and release properties.

[0058] The delivery operation member 52 has a support shaft 52a, an operation portion 52b (the other end), and a flexure arm 52c (one end) in an integral manner in addition to the anti-return claw 52e. The support shaft 52a has both ends embedded and held in the concave housing portion 22 and the first fixed cover 23 at the lower side of the tape delivery passage 14a, and supports the pair of delivery rollers 51 so that they can rotate. The operation portion 52b (the other end) is integrally supported by the support shaft 52a at the base end side, and is formed into a trigger shape at the front end side protruding to the outside of the housing body 12 so as to be able to receive the aforementioned delivery operation input of the tape T1. The flexure arm portion 52c (one end portion) protrudes from the operating portion 52b and extends along the rotation direction of the support shaft portion 52a. The flexure arm portion 52c drives the internal toothed claw gear 51a of the feed roller 51 to rotate according to the operation of the operating portion 52b in the direction of arrow D1 through the check claw 52e supported on the front end side. When the operating portion 52b is reset to the initial position, the check claw 52e is supported in a manner allowing the check claw 52e to move in the climbing and disengagement direction relative to the internal toothed claw gear 51a of the feed roller 51.

[0059] A pair of annular delivery belts 53 are respectively formed of a material having rubber elasticity into a ring shape with a roughly circular cross-section, and are wound around a pair of delivery rollers 51 and a front end support roller 54. When the delivery operation input of the tape T1 is input into the delivery operation component 52 and the pair of delivery rollers 51 rotate in the tape delivery direction, the upper half that contacts the adhesive surface portion of the tape T1 is moved from the pair of delivery rollers 51 to the front end support roller 54 side according to the rotation angle, thereby enabling the tape T1 to be delivered.

[0060] One end 56a of the torsion coil spring 56 is locked in the inner groove portion 52d of the belt stopper of the operating portion 52b, and the other end 56b is locked in the locking protrusion 22e of the concave housing portion 22 near the tape delivery passage 14a, and the middle spiral portion 56c is sleeved on the support shaft portion 52a of the delivery operating member 52. Of course, the torsion coil spring 56 can also be composed of other torsion springs (torsion springs) having the same function.

[0061] According to the above structure, the delivery operation member 52 can be moved along the curved outer wall surface of the second storage housing portion 22d and the second fixed cover 24 in the tape delivery tube 14, overcoming the rebound force of the torsion coil spring 56 and moving from Figure 3 The solid line position in the figure is operated to the tape delivery direction side toward the virtual line position. On the other hand, the rebound force of the torsion coil spring 56 can be reset to Figure 3 The initial position is shown by the solid line.

[0062] The cutting mechanism 16 includes a cutting operation member 61, a cutting blade 62, a compression coil spring 63 for return (a second return spring), and a tape pressing member 64. The cutting operation member 61 can rotate in a manner of protruding from the housing body 12 or retracting from the protruding state, the cutting blade 62 is mounted on the rotation end side of the cutting operation member 61, the compression coil spring 63 for return (a second return spring) applies force to the cutting operation member 61 toward the protruding position side relative to the housing body 12, and the tape pressing member 64 presses a portion of the tape T1 facing the inner wall portion of the opening 11 against the inner wall surface from the spacer side.

[0063] And, when the cut-off operation member 61 is switched from Figure 3 When the protruding position indicated by the solid line is rotated to the retracted position indicated by the virtual line in the figure, the cutting mechanism 16 separates the leading end portion T1a of the tape T1 in the feeding direction from the trailing portion T1b on the tape roll R1 side near the opening 11.

[0064] Specifically, the cutting operation member 61 comprises: a rotation fulcrum portion 61a (one end portion) at one end side, a stopper portion 61b (the other end portion) at the other end side, an operation surface 61c, and an intermediate lower surface portion 61d. The rotation fulcrum portion 61a (one end portion) at one end side is rotatably supported on the outer wall portion of one side of the adhesive tape T1a delivered from the opening 11 in the adhesive tape delivery cylinder 14, namely, the second storage housing portion 22d of the concave housing portion 22 and the second fixed cover 24, the stopper portion 61b (the other end portion) at the other end side is provided with a cutting blade 62 having a blade tip facing the adhesive tape T1a, the operation surface 61c is provided for pressing operation, and the intermediate lower surface portion 61d receives the rebound force from the compression coil spring 63 for reset.

[0065] In the cutting operation member 61, a rotation fulcrum portion 61a at one end is rotatably supported relative to the shell body 12 on the winding body storage portion 13 side, and a limit portion 61b at the other end can be displaced in a manner of appearing and disappearing from the tape delivery cylinder 14 on the opening 11 side.

[0066] like Figure 3 As shown, the cutting blade 62 is set to the following length: Figure 3 At the protruding position shown by the solid line, when the stopper 61b on the other end side contacts the second storage housing portion 22d of the concave housing portion 22 and the second fixing cover 24 from the inside, the tip of the blade is located above the tape delivery passage 14a.

[0067] In addition, the cutting blade 62 is moved to the position of the cutting operation member 61. Figure 3At the immersed position shown by the virtual line in the middle, when the limiting portion 61b on the other end side approaches the tape delivery passage 14a, its blade tip drops to the lower side of the tape delivery passage 14a, and the tape T1 can be cut off from the separator side by separating it from the subsequent portion T1b on the tape winding body R1 side near the inner wall portion of the opening 11.

[0068] like Figure 3 as well as Figure 6 As shown, the tape pressing member 64 has a base end 64a, a pressing plate portion 64b on the front end side, and left and right flexure arms 64c. The base end 64a is supported by the cutting operation member 61, the pressing plate portion 64b on the front end side is formed into a substantially L-shaped curved shape capable of pressing a portion of the tape T1 facing the inner wall portion of the opening 11 from the spacer side against the inner wall surface, and the left and right flexure arms 64c connect the base end 64a and the pressing plate portion 64b, and always generate a force in the direction of pushing the pressing plate portion 64b.

[0069] When the cut-off operating member 61 is reset to the position due to the reset force of the compression coil spring 63, Figure 3 When the tape pressing member 64 is in the protruding position shown by the solid line in the figure, the tape pressing member 64 is constrained by the cutting operation member 61 to the upper standby position shown by the solid line in the figure. Figure 3 When at the retracted position indicated by the imaginary line, the tape pressing member 64 applies force in the direction of pressing the pressing plate portion 64 b via the left and right flexure arms 64 c , thereby pressing the tape T1 against the inner wall surface before the tape T1 is cut by the cutting blade 62 .

[0070] Thus, in this embodiment, the cutting operation component 61 of the cutting mechanism part 16 is arranged to be able to emerge and retract from the outer wall part on one side of the tape in the tape delivery cylinder 14 toward the outside of the one side, and on the other hand, the delivery operation component 52 of the delivery mechanism part 15 can be moved along the outer wall part on the other side of the tape delivery cylinder 14.

[0071] like Figure 7 As shown, the tape cutter 10 has a first placement surface 17 composed of two parallel protrusions 71 and 72 on the side opposite to the tape delivery tube 14 relative to the winding body storage portion 13. When the first placement surface 17 is placed approximately horizontally on a support table upper surface 91 such as a workbench or a table upper surface and is in a first posture supported by the support table upper surface 91, the tape cutter 10 can stand in a vertical posture with the tape delivery tube 14 located vertically upward. Therefore, at this time, for example, while holding the tape cutter 10 with one hand from the front side, the delivery operation member 52 of the delivery mechanism 15 can be operated in the direction of arrow D1 relative to the housing body 12 with the fingers of the one hand, or the cutting operation member 61 of the cutting mechanism 16 can be operated in the direction of arrow D2.

[0072] If the Figure 7 As shown, the housing body 12 has a flat opening side end surface 12b, a first curved side surface 12c (one side outer wall portion), a second curved side surface 12d, and a third curved side surface 12e (the other side outer wall portion). Among them, the flat opening side end face 12b and the flat surface 12a on which the protrusions 71 and 72 of the first loading surface 17 are protrudingly provided form a predetermined intersection angle and are inclined, the first curved side surface 12c (the outer wall portion on one side) is circularly bent with the same curvature radius on one side side of one end side of the first loading surface 17 from the winding body storage portion 13 to the tape delivery cylinder 14, the second curved side surface 12d is roughly circularly bent with a smaller curvature radius than the first curved side surface 12c on the other side side of the other end side of the first loading surface 17 and around the winding body storage portion 13, the third curved side surface 12e (the outer wall portion on the other side) is roughly circularly bent with a smaller curvature radius than the second curved side surface 12d on the other side side of the tape delivery cylinder 14, and the generatrix of the entire circumference of the outer side surface of the shell body 12 formed as a whole is parallel.

[0073] In addition, if Fig. 8A As shown, in the tape cutter 10 of the present embodiment, when the setting posture of the housing body 12 is the second horizontal posture in which the cutting operation member 61 of the cutting mechanism portion 16 faces the vertical downward side, the operating surface 61c (which may be a part) of the cutting operation member 61 and the first curved side surface 12c as the outer wall surface of the winding body storage portion 13 constitute the second placement surface 73 having two line contact portions or / and surface contact portions similar in function to the protrusions 71 and 72. And when the second placement surface 73 is supported on the upper surface 91 of the support table in a substantially horizontal manner, the delivery operation member 52 of the delivery mechanism portion 15 can be self-supporting in a state in which it is located on the vertical upward side, the delivery operation member 52 can be easily operated in the direction of the arrow D1, and the housing body 12 can be rotated in the direction of the arrow D3 to press the cutting operation member 61 of the cutting mechanism portion 16.

[0074] Moreover, if Figure 8BAs shown, in the tape cutter 10 of the present embodiment, when the shell body 12 takes the third posture in which the delivery operation member 52 of the delivery mechanism portion 15 is located on the vertically lower side, the delivery operation member 52 and the winding body storage portion 13 form a third loading surface portion 74 having two parallel line contact portions or / and surface contact portions that are functionally similar to the protrusions 71 and 72. When the third loading surface portion 74 is supported to be approximately horizontal, the cutting operation member 61 of the cutting mechanism portion 16 is located on the vertically upper side and can be self-supporting, the cutting operation member 61 can be easily pressed in the direction of the arrow D2, and the shell body 12 can be slid on the upper surface 92 of the support table with the abutment step 92a in the direction of the arrow M1, thereby operating the delivery operation member 52 of the delivery mechanism portion 15 in the direction of the arrow D1.

[0075] In addition, the tape cutter 10 of this embodiment may also be configured such that the first placement surface 17 is orthogonal to the upper surface 91 of the support table. Fig. 8A or Figure 8B The horizontal posture shown is tilted forward and backward, such as Fig. 9 As shown, the delivery operation member 52 of the delivery mechanism 15 and the cutting operation member 61 of the cutting mechanism 16 can be operated with one hand in a state where the housing body 12 is in contact with the support table upper surface 91 at one side in the thickness W direction.

[0076] Next, the action will be described.

[0077] In the present embodiment constructed as described above, the cutting operation member 61 of the cutting mechanism 16 is arranged to be able to appear and disappear on one side of the tape delivery tube 14, and on the other hand, the delivery operation member 52 of the delivery mechanism 15 is arranged to be able to move along the outer wall portion of the other side of the tape delivery tube 14. Figure 1 Move in the direction of arrow D1.

[0078] Therefore, the cutting operation component 61 and the feeding operation component 52 are respectively arranged on the two sides of the tape T1 fed out from the tape feeding cylinder 14, and the respective operation directions are obviously different in the direction approximately orthogonal to the two outer wall portions of the tape feeding cylinder 14 or in the direction along the wall surface. The function and operation direction of each operating part are clear and easy to understand, and the user can choose an easy operating posture.

[0079] In particular, in the present embodiment, a trigger-shaped delivery operating component 52 for delivering the tape and a button-shaped cutting operating component 61 for cutting the tape are arranged on both sides of the opening 11 at the front end of the tape delivery cylinder 14 protruding from the winding body storage portion 13 in the delivery direction of the tape T1. Therefore, when the shell body 12 is held in the palm of the hand, any one of the delivery operating component 52 and the cutting operating component 61 can be easily operated in the operating direction with the approaching fingers.

[0080] Moreover, not only in the holding posture, but also in any of the self-standing postures from the first to the fourth postures described above, since it is sufficient to perform a simple operation of pushing the feeding operation component 52 and the cutting operation component 61 in one direction, it is possible to select any posture that is easy to operate the tape cutter 10, and it is possible to provide a tape cutter that is easy to operate and convenient for any user.

[0081] For example, by taking Figure 7 The first posture shown does not require holding the roll storage unit 13, and the operator can push the delivery operation member 52 and the cutting operation member 61 in a predetermined direction while holding the tape delivery cylinder 14 or pressing the roll storage unit 13 against the upper surface 91 of the support table. Of course, the operator can easily hold the housing body 12 in the first posture.

[0082] In addition, by adopting Fig. 8A In the second posture shown, the delivery operation member 52 located on the vertical upper side can be easily moved along the third curved side surface 12e of the tape delivery cylinder 14 with one hand, and the housing body 12 can be tilted to press the cutting operation member 61.

[0083] Moreover, by adopting Figure 8B In the third posture shown, the cutting operation member 61 can be easily pressed in the direction of sinking into the tape delivery tube 14, and the delivery operation member 52 can be operated while the housing body 12 is abutted against the abutting step 92a and the tape attachment object.

[0084] In addition, in the present embodiment, the loading and unloading cover portion 21 can be detached from the concave shell portion 22 to open the winding body storage portion 13 and one side of the tape delivery passage 14a, thereby making it easy to install the tape winding body R1 and to introduce the tape T1 pulled out from the tape winding body R1 into the tape delivery passage 14a.

[0085] In addition, the cutting operation component 61 is rotatably supported on the shell body 12 at the rotation fulcrum portion 61a on the side of the winding body storage portion 13, and the cutting blade 62 is installed on the limiting portion 61b on the side of the opening 11 from which the tape delivery cylinder 14 emerges and disappears. Therefore, the movement of the cutting blade 62 corresponds to the displacement of the other end side of the cutting operation component 61, and the operation direction is clear and easy to understand.

[0086] Furthermore, the delivery mechanism 15 has a simple structure and excellent reliability because the delivery roller 51 with the claw gear 51a and the delivery operation member 52 with the anti-return claw 52e constitute a ratchet mechanism that operates in accordance with the delivery operation of the operation portion 52b.

[0087] Thus, in the tape cutter 10 of the present embodiment, the operation direction of the feeding operation member 52 for feeding the tape and the cutting operation member 61 for cutting the tape are clear from the perspective of their shapes and configurations, and the functions of the operation parts can be easily understood by anyone. Furthermore, the feeding operation member 52 and the cutting operation member 61 can be easily operated even in any self-standing posture that is easy to operate among a variety of postures. Therefore, a tape cutter that can be easily operated by any user and is easy to use and has a high degree of freedom can be provided. As a result, a sufficient improvement is also achieved from the perspective of universal design.

[0088] As described above, the present invention can provide a tape cutter that has clear and easy-to-understand functions and operation directions of the operation parts, and is easy to operate and use by any user. The present invention is useful for all tape cutters, especially manual cutters that are suitable for tape rolls and can be operated with one hand.
