[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2007-30905 Summary of the Invention [Problem to be solved by the invention]

[0005] However, when such a binding device is repeatedly used to cut adhesive tape, the cutter inevitably wears out. This requires the cutter and other consumable parts, such as peripheral parts that operate together with the cutter, to be replaced from time to time. However, the cutter and other consumable parts are built into the main body, making them difficult to replace without disassembling the main body.

[0006] SUMMARY OF THE INVENTION The present invention provides a binding device and a cartridge for a binding device that can reduce the time and effort required for replacing consumables and improve usability.

[0007] A binding device according to one aspect of the present invention is a binding device that binds an object to be bound by using a ring-shaped portion of adhesive tape that has one adhesive side facing upwards, by pulling out the tape with the adhesive side facing upwards and pressing the object to be bound against the adhesive side, thereby forming a ring-shaped portion of the adhesive tape that adheres to the object to be bound and a self-adhesive portion that is continuous with the ring-shaped portion and where the adhesive sides are bonded to each other. The binding device comprises: a base body that can be placed on a mounting surface and includes a tape holding portion that rotatably holds the roll-shaped adhesive tape; and a sealer body that is positioned forward of the tape holding portion in the fore-and-aft direction of the base body in the direction in which the adhesive tape is pulled out, and is detachably attached to the base body. The sealer body has a case that is supported by the base body and forms at least a part of a slit-shaped guide path along which the object to be bound is guided together with the pulled-out adhesive tape, and a cutter that is provided on the case and that cuts the self-adhesive portion that is formed when the object to be bound moves downstream of the guide path.

[0008] In the above-mentioned binding device, the cutter may have a pressed body that operates between a protruding position where at least a portion of the cutter is positioned within the guide path and a retracted position where the cutter is pressed downstream by the binding object at the protruding position, thereby reducing the area of ​​the cutter positioned within the guide path compared to the protruding position; a biasing member that is interposed between the case and the pressed body and biases the pressed body toward the protruding position; and a blade body that is connected to the pressed body and has at least the cutting edge that protrudes from the inside of the case toward the self-attaching portion into the guide path as the pressed body moves from the protruding position to the retracted position.

[0009] In the binding device, the sealer body may further include a guide roller that is rotatably supported relative to the case and that rotates to wind the adhesive tape around the sealer body and guide the adhesive tape toward the guide path.

[0010] In the above-mentioned binding device, the base body has a plurality of case support portions, each of which is rod-shaped or protruding and extends in the direction of the rotation axis of the adhesive tape, and which are arranged at intervals from each other, and the case may have a movement restriction surface that engages with the plurality of case support portions and restricts movement of the case relative to the base body.

[0011] In the above-mentioned binding device, the sealer body may further have an auxiliary tape holding portion that holds a roll of auxiliary adhesive tape having an outer diameter and an inner diameter smaller than those of the roll of adhesive tape, and it may be possible to bind the object to be bound using the auxiliary adhesive tape.

[0012] In the binding device, the base body may be configured such that a pair of the sealer bodies can be attached to the base body with a gap between them in the front-rear direction.

[0013] In the binding device, the front-to-rear dimension and the height dimension perpendicular to the front-to-rear direction and the rotation axis direction of the adhesive tape may be smaller for the sealer body than for the base body.

[0014] In the binding device, a surface of the case facing the downstream side of the guide path may be provided with a suction cup attachment portion for attaching a suction cup that can be attached to the installation surface.

[0015] A cartridge for a binding device according to one embodiment of the present invention is a cartridge for a binding device that is detachably attached to a base body of a binding device that binds an object to be bound by pulling out a roll of adhesive tape with one side adhesive, with the adhesive side facing upward, and pressing the object to be bound against the adhesive surface, thereby forming a ring-shaped portion on the adhesive tape that adheres to the object to be bound, and a self-adhesive portion where the adhesive surfaces are bonded to each other and are continuous with the ring-shaped portion.The cartridge is detachably attached to a base body of a binding device that binds an object to be bound by the ring-shaped portion, and includes a tape holding portion that rotatably holds the roll of adhesive tape, and a case that is detachably attached to the base body in front of the tape holding portion in the fore-and-aft direction of the base body, and that is forward of the tape holding portion in the pulling-out direction of the adhesive tape, and that forms at least a part of a slit-shaped guide path along which the object to be bound is guided together with the pulled-out adhesive tape, and a cutter that is provided in the case and cuts the self-adhesive portion that is formed when the object to be bound moves downstream of the guide path.

[0016] In the above-mentioned cartridge for the binding device, the case may have a recessed portion recessed from the outer surface of the case at a position that does not interfere with the guide path, and the inner surface of the recessed portion may have a movement restriction surface that engages with a rod-shaped or protrusion-shaped case support portion on the base body to restrict movement of the case relative to the base body.

[0017] In the above-mentioned cartridge for a binding device, the recessed portion may be shaped like a hook that can be hooked onto the case support portion. [Effects of the Invention]

[0018] The above-described binding device and binding device cartridge can reduce the time and effort required for replacing consumables and improve usability. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0020] Hereinafter, a binding device 100 according to an embodiment of the present invention will be described in detail with reference to the drawings. 1 and 2, the binding device 100 is a device that binds an object to be bound K as shown in Fig. 3 while unwinding a roll of adhesive tape T. In this embodiment, the object to be bound K is, for example, a packaging bag, and the binding device 100 is a so-called bag sealer that is used to bind and seal the bag opening of the object to be bound K.

[0021] Returning to FIGS. 1 and 2, the adhesive tape T is a sealing tape having an adhesive surface F1 coated on only one side thereof, and is wound around a circular core X to form a roll.

[0022] (Overall composition) Specifically, the binding device 100 includes a base body 1 that holds a roll of adhesive tape T, and a sealer body (binder cartridge) 2 that is detachably attached to the base body 1.

[0023] (base body) In this embodiment, the base body 1 is composed of two plate-like members 10 that face each other at a distance in the direction of the rotation axis of the adhesive tape T, and has a generally rectangular plate shape as a whole. Hereinafter, the rotation axis direction of the adhesive tape T is defined as the "device thickness direction" D1. A flange-like portion 10a extending in the device thickness direction D1 is formed at the lower end of each plate-like member 10 in a height direction D2 (hereinafter referred to as the device height direction D2), which is perpendicular to the device thickness direction D1. The flange-like portion 10a of one plate-like member 10 and the flange-like portion 10a of the other plate-like member 10 extend away from each other. In other words, each plate-like member 10 is L-shaped when viewed in a front-rear direction D3 (hereinafter referred to as the device front-rear direction D3), which is perpendicular to the device thickness direction D1 and the device height direction D2. The front-rear direction D3 is the plane direction of the installation surface M, which will be described later.

[0024] The flange-shaped portion 10a faces the installation surface M, allowing the base body 1 to be installed on the installation surface M. The flange-shaped portion 10a is provided with, for example, an anti-slip rubber G, a suction cup Q that can be attached to the installation surface M, or the like.

[0025] Furthermore, a slit-shaped roller holding groove 10b extending downward from the upper end surface is formed near the rear end of each plate-like member 10. The base body 1 further has a tape roller (tape holding portion) 11 with a shaft portion 11j disposed within this roller holding groove 10b. The tape roller 11 is fitted inside the roll of adhesive tape T and is disposed between the roller holding grooves 10b of the pair of plate-like members 10. The tape roller 11 is rotatable relative to the base body 1, and as a result, the base body 1 rotatably holds the adhesive tape T. In this embodiment, the roller holding groove 10b is also provided near the front end of each plate-like member 10.

[0026] As shown in FIG. 4A, the tape width wt of the adhesive tape T is smaller than the width w11 of the outer peripheral surface 11a of the tape roller 11 in the device thickness direction D1. A plurality of positioning protrusions 11b, 11c are formed on both end edges 11x, 11y of the outer peripheral surface 11a of the tape roller 11 in the device thickness direction D1, spaced apart in the circumferential direction of the tape roller 11. These positioning protrusions 11b, 11c sandwich the rolled adhesive tape T from both sides in the device thickness direction D1. In this embodiment, the positioning protrusions 11b on one edge 11x side in the device thickness direction D1 and the positioning protrusions 11c on the other edge 11y side are arranged alternately. That is, as shown in FIG. 4B, the positioning protrusions 11b, 11c are arranged at equal intervals in the circumferential direction, and each positioning protrusion 11c is located exactly midway between two adjacent positioning protrusions 11b in the circumferential direction.

[0027] As shown in FIG. 5, the base body 1 is provided with a plurality of case support parts 12 that connect a pair of plate-like members 10 together. Each case support part 12 is rod-shaped (e.g., round rod-shaped) extending in the device thickness direction D1 and is arranged at intervals from one another. These case support parts 12 are members that support the sealer main body 2, which will be described in detail later. The case support parts 12 are detachably fixed to the plate-like member 10 with screws N (see FIGS. 1 and 2) so that their installation positions can be changed to match the shape of the sealer main body 2, which will be described later, and the number of case support parts 12 that can be installed can be increased or decreased. Therefore, through holes 10x through which the screws N can be inserted are formed at various positions in the plate-like member 10.

[0028] In this embodiment, a first support portion 12a, a second support portion 12b, and a third support portion 12c are provided as case support portions 12 for supporting the sealer main body 2, which will be described in detail later. The first support portion 12a is provided at a position near the upper end and front end of the base body 1. The second support portion 12b is provided below the first support portion 12a. The third support portion 12c is provided below the second support portion 12b and forward of the first support portion 12a and the second support portion 12b. The third support portion 12c is provided at approximately the center of the base body 1 in the device height direction D2.

[0029] (Sheila body) 1 and 2, the sealer body 2 is provided on the base body 1 in front of the tape roller 11 in the device front-rear direction D3, which is ahead of the tape roller 11 in the direction in which the adhesive tape T is pulled out. In this embodiment, the sealer body 2 is attached to the base body 1 so as to be sandwiched between a pair of plate-like members 10 that constitute the base body 1.

[0030] 6, the sealer body 2 has a case 20 supported by the base body 1, and a guide roller 30, a cutter 40, and an auxiliary tape holder 50 provided in the case 20. The sealer body 2 has a smaller projected area on an imaginary plane perpendicular to the device thickness direction D1 than the base body 1. In other words, the dimensions of the sealer body 2 in the device height direction D2 and the device front-to-rear direction D3 are smaller than those of the base body 1, making the sealer body 2 smaller than the base body 1.

[0031] (case) The case 20 is made of, for example, resin or non-ferrous metal, and has a generally rectangular plate shape. The case 20 has a slit-like guide path 21 formed therein, along which the drawn-out adhesive tape T and the object to be bound K are guided. When the case 20 is supported on the base body 1, the guide path 21 is arranged at the position of the roller holding groove 10b. Therefore, the guide path 21 is exposed in the device thickness direction D1.

[0032] The guide path 21 is formed on the outer surface 20a, which faces in a direction intersecting the thickness direction of the case 20 (the device thickness direction D1), so as to extend obliquely rearward from an entrance 21x that opens upward in the device height direction D2, toward the downward (downstream) side. The guide path 21 penetrates the case 20 in the device thickness direction D1 and has a front inner surface 21a located on the front side and a rear inner surface 21b located on the rear side. A part of the object to be bound K (at least the portion to be bound) can be placed inside the guide path 21.

[0033] Here, an object to be bound K can be inserted from an entrance 21x of the guide path 21. An exit 21y, which is the downstream end of the guide path 21, does not open to the outer surface 20a of the case 20 but is located inside the case 20, and a pressed body 43, which will be described later, is disposed near the exit 21y.

[0034] The case 20 also has an escape space 22 that extends rearward from the outlet 21y, which is the downstream end of the guide path 21, to expand the space within the guide path 21. The escape space 22 penetrates the case 20 in the device thickness direction D1, similar to the guide path 21, and is located inside the case 20 without opening to the outer surface 20a of the case 20. When the case 20 is supported on the base body 1, the escape space 22 is located at the position of the roller holding groove 10b. Therefore, the escape space 22 is exposed in the device thickness direction D1.

[0035] In addition, a suction cup attachment portion 23 for attaching a suction cup Q1 that can be attached to an installation surface is provided on a lower surface 20c of the outer surface 20a of the case 20. In this embodiment, a pair of the suction cup attachment portions 23 are provided at an interval from each other in the front-rear direction D3 of the device.

[0036] Furthermore, case 20 is formed with a recessed portion 24 recessed from outer surface 20a at a position that does not interfere with guide path 21. In this embodiment, a plurality of recessed portions 24 are formed in case 20, and as recessed portion 24, first recessed portion 25 that opens to front surface 20b facing forward of outer surface 20a of case 20 and extends upward and rearward from front surface 20b, and second recessed portion 26 that extends upward and forward from bottom surface 20c facing downward of outer surface 20a, are formed in case 20.

[0037] The first recessed portion 25 has a hook shape that can be hooked from above and behind onto the first support portion 12a (see FIG. 5) of the base body 1. More specifically, the inner surface of the first recessed portion 25 has a first inclined inner surface 25a that faces rearward and gradually slopes upward as it approaches rearward, a second inclined inner surface 25b that is connected to the upper edge of the first inclined inner surface 25a and slopes downward as it approaches rearward, and a third inclined inner surface 25c that is connected to the lower edge of the second inclined inner surface 25b and slopes gradually downward as it approaches frontward.

[0038] With the first recessed portion 25 hooked onto the first support portion 12a, the first support portion 12a is disposed at the upper end of the first recessed portion 25, which is the connection position between the first inclined inner surface 25a and the second inclined inner surface 25b, and the outer peripheral surface of the first support portion 12a faces and engages (abuts) with a part of the first inclined inner surface 25a and a part of the second inclined inner surface 25b, thereby restricting downward and forward movement of the case 20 relative to the base body 1. In other words, the part of the first inclined inner surface 25a and the part of the second inclined inner surface 25b facing the first support portion 12a form a movement restricting surface.

[0039] Furthermore, when the first recessed portion 25 is hooked onto the first support portion 12a, the outer peripheral surface of the second support portion 12b of the base body 1 abuts against the third inclined inner surface 25c of the first recessed portion 25 from the front, thereby restricting forward movement of the case 20 relative to the base body 1. Therefore, a portion of the third inclined inner surface 25c facing the second support portion 12b forms a movement restricting surface. Note that this movement restricting surface of the third inclined inner surface 25c has a curved surface shape that follows a partial circumferential region of the outer peripheral surface of the second support portion 12b.

[0040] Furthermore, in a state in which the first recessed portion 25 is hooked onto the first support portion 12a, the outer peripheral surface of the third support portion 12c of the base body 1 engages (abuts) with the front surface 20b below the third inclined inner surface 25c, thereby restricting forward movement of the case 20 relative to the base body 1. Therefore, a part of the front surface 20b facing the third support portion 12c constitutes a movement restricting surface.

[0041] (Guide roller) The guide roller 30 is supported by the case 20 so as to be rotatable about a rotation axis extending in the device thickness direction D1. In this embodiment, the guide roller 30 is a sprocket, is arranged near the entrance 21x of the guide path 21, and has a plurality of teeth 31 formed in the rotation direction, at least the tips of which can protrude from the rear inner surface 21b of the guide path 21 toward the front inner surface 21a.

[0042] The guide roller 30 then rotates to wind the adhesive tape T around the tooth tips and guide it toward the guide path 21. That is, when viewed from above, the guide roller 30 rotates from rear to front. The guide roller 30 winds the adhesive tape T in a position where the adhesive surface F1 of the adhesive tape T faces upward and the non-adhesive surface F2 opposite to the adhesive surface F1 faces the tooth tips of the teeth 31.

[0043] The guide roller 30 receives the object to be bound K inserted downward from the entrance 21x of the guide path 21 between two teeth 31 adjacent in the rotational direction, and by rotating the guide roller 30 while pressing the adhesive surface F1 of the adhesive tape T downward with the object to be bound K, the adhesive tape T and the object to be bound K are guided downstream of the guide path 21, i.e., downward, while binding the object to be bound K with the adhesive tape T.

[0044] Furthermore, while the object to be bound K is guided downstream of the guide path 21 by the rotation of the guide roller 30, the adhesive tape T is formed with a ring-shaped portion R with the adhesive surface F1 facing inward, and a self-adhesive portion J continuous with the ring-shaped portion R and in which the adhesive surfaces F1 are bonded to each other (see Figure 3).

[0045] Here, the surface of the front inner surface 21a of the guide path 21 at the end on the entrance 21x side is constituted by a pressing member 32 that is biased toward the tips of the teeth 31 of the guide roller 30. For example, if the case 20 is made of resin, the pressing member 32 is a leaf spring that is molded integrally with the case 20. The pressing member 32 sandwiches the adhesive tape T between itself and the tips of the teeth 31, and forms the self-adhesive portion J on the adhesive tape T.

[0046] (cutter) The cutter 40 cuts at a predetermined position the self-adhesive portion J of the adhesive tape T that is formed when the object to be bound K moves downstream of the guide path 21. Specifically, the cutter 40 has a lever 41 that rotates about an axis of rotation that extends in the thickness direction D1 of the device. The lever 41 is provided with a blade body 42 that cuts the self-adhesive portion J, a pressed body 43 that is pressed downward by the object to be bound K, and a biasing member 44 that is arranged between the lever 41 and the case 20.

[0047] 7(a) and 7(b), the pressed body 43 moves between a protruding position P1 where at least a portion of the pressed body 43 is positioned within the guide path 21 downstream of the guide roller 30, and a retracted position P2 where the pressed body 43 is pressed downstream of the guide path 21 by the object to be bound K at the protruding position P1, thereby reducing the area of ​​the pressed body 43 positioned within the guide path 21 compared to the protruding position P1. In this embodiment, the pressed body 43 protrudes forward from the rear inner surface 21b of the guide path 21 into the guide path 21, and retracts rearward from the rear inner surface 21b.

[0048] The biasing member 44 is an elastic body such as a coil spring, and is provided between the lever 41 and the case 20 (see FIG. 6). That is, the biasing member 44 is interposed between the case 20 and the pressed body 43, and biases the pressed body 43 toward the protruding position P1.

[0049] The blade body 42 is connected to the pressed body 43 via the lever 41. As the pressed body 43 moves from the protruding position P1 to the retracted position P2, the lever 41 rotates, causing at least the blade tip to protrude from the inside of the case 20 toward the self-adhering portion J into the guide path 21 downstream of the guide roller 30. In this embodiment, the blade body 42 protrudes forward from the rear inner surface 21b of the guide path 21 into the guide path 21 as the pressed body 43 moves toward the retracted position P2. When the pressed body 43 is positioned at the retracted position P2, a portion of the blade body 42 is located forward of the front inner surface 21a. Furthermore, the blade body 42 retracts rearward from the rear inner surface 21b of the guide path 21 into the case 20 as the pressed body 43 moves toward the protruding position P1.

[0050] Returning to FIG. 6 , the auxiliary tape holding unit 50 is provided integrally with the case 20 at the upper rear end thereof. It is capable of holding a roll of auxiliary adhesive tape Ts separate from the adhesive tape T. The outer and inner diameters of the roll of auxiliary adhesive tape Ts are smaller than those of the roll of adhesive tape T. The auxiliary tape holding unit 50 is disposed rearward of the guide roller 30 and holds the auxiliary adhesive tape Ts so as to sandwich it from both sides in the device thickness direction D1 and to rotatably hold it so that it can be pulled out toward the guide roller 30. The pulled-out auxiliary adhesive tape Ts is guided by the guide roller 30 to the guide path 21 and can be used to bind the object to be bound K in the same way as the adhesive tape T.

[0051] 8, the auxiliary tape holding portion 50 can hold the adhesive tape T and an adhesive tape having the same inner diameter as the adhesive tape T. The auxiliary tape holding portion 50 may be detachable from the case 20.

[0052] (auxiliary cutter) Returning now to Figure 5, in this embodiment, an auxiliary cutter 5 is detachably attached to the front of the base body 1. The auxiliary cutter 5 is disposed facing the case 20 of the sealer body 2 from the front, and is disposed so as to sandwich the first support portion 12a, the second support portion 12b, and the third support portion 12c of the base body 1 together with the case 20 of the sealer body 2 in the front-to-rear direction D3 of the device. The auxiliary cutter 5 has a case 5a and a blade main body 5b provided on the case 5a. The auxiliary cutter 5 is used, for example, when removing adhesive tape T from an object to be bound K after binding.

[0053] (Action and effect) In the binding device 100 of the present embodiment described above, the sealer body 2, which is constituted by the case 20 in which the cutter 40 is provided, is detachable from the base body 1. Therefore, if the cutter 40 becomes worn due to repeated use and needs to be replaced, the sealer body 2 can be replaced as a whole, making it possible to easily replace the cutter 40 without disassembling the binding device 100, for example. In other words, it is possible to reduce the effort required to replace consumables and improve usability.

[0054] In particular, in this embodiment, the cutter 40, which is composed of the blade body 42, the pressed body 43, and the lever 41 equipped with the urging member 44, can be replaced together with the case 20, thereby avoiding the extremely time-consuming task of individually removing and assembling each of the blade body 42, the pressed body 43, and the urging member 44 when replacing the cutter 40.

[0055] Similarly, since the guide rollers 30 are also provided in the case 20, replacement of the guide rollers 30 is also easy.

[0056] Furthermore, by engaging the movement restricting surfaces of the case 20 with the multiple case support parts 12 provided on the base body 1, when the sealer body 2 is attached to the base body 1, not only is movement of the sealer body 2 restricted relative to the base body 1 but rotation is also restricted, allowing for binding work on the objects to be bound K in a stable posture. In addition, because such movement restricting surfaces of the case 20 are the inner surfaces of the recessed parts 24 provided on the case 20, positioning of the sealer body 2 when attaching it to the base body 1 is easy. Furthermore, because the first recessed part 25 of the recessed parts 24 is hook-shaped, the first recessed part 25 can be easily engaged with the case support parts 12, making it easy to attach the sealer body 2 to the base body 1.

[0057] Furthermore, the case 20 is provided with an auxiliary tape holding portion 50, which makes it possible to use the sealer body 2 alone to bind the object K to be bound. In particular, in this embodiment, the sealer body 2 is made smaller than the base body 1, making it easier to carry the sealer body 2 and improving usability. Furthermore, the sealer body 2 is equipped with suction cups Q1, which can be attached to the sealer body 2, allowing for stable binding work by adhering the suction cups Q1 to the installation surface M even with only the sealer body 2.

[0058] The present invention is not limited to the above-described embodiment, and it goes without saying that various modifications can be made without departing from the spirit of the present invention.

[0059] For example, as shown in Fig. 9, a pair of sealer bodies 2 may be attached to the base body 1 at a distance from each other in the front-to-back direction D3 of the device. In this case, the sealer body 2 provided on the front side is attached to the base body 1 with the front of the auxiliary adhesive tape Ts in the unwinding direction aligned with the front in the front-to-back direction D3 of the device, and the sealer body 2 provided on the rear side is attached to the base body 1 with the front of the auxiliary adhesive tape Ts in the unwinding direction aligned with the rear in the front-to-back direction D3 of the device. In this case, the base body 1 has a symmetrical shape in the front-to-back direction D3 of the device. By configuring the binding device 100 in this way, it is possible to use auxiliary adhesive tapes Ts of different colors, for example, as desired.

[0060] The shape of the base body 1 is not particularly limited, and the sealer body 2 may be attached to the outer surface of a plate-shaped base body. Specifically, as shown in FIG. 10, a pair of plate-shaped members 10 constituting the base body 1 are brought into contact with each other in the device thickness direction D1 to form a single plate-shaped member 10A. A case support 12 is provided on the surface of this plate-shaped member 10A facing one side in the device thickness direction D1, and the sealer body 2 can be attached to the outer surface of the plate-shaped member 10A. In this case, the objects to be bound K are bound using auxiliary adhesive tape Ts (see FIG. 6) attached to the sealer body 2. While FIG. 10 shows the sealer body 2 attached to one side of the plate-shaped member 10A, the sealer body 2 can also be attached to both sides of the plate-shaped member 10A. In this case, a large-diameter adhesive tape T can be used instead of the small-diameter auxiliary adhesive tape Ts.

[0061] Furthermore, the guide roller 30 may be provided on the base body 1 rather than on the sealer body 2. Furthermore, the guide path 21 along which the adhesive tape T and the object to be bound K are guided may be formed between the sealer body 2 and the base body 1. In other words, a portion of the guide path 21 may be formed in the case 20, and the remaining portion may be formed in the base body 1.

[0062] Furthermore, the case support portion 12 is not limited to a rod-shaped member provided between the plate-shaped members 10, and may be, for example, a protrusion protruding from a surface of the plate-shaped member 10 facing the device thickness direction D1. In this case, the recessed portion 24 of the case 20 that engages with the protruding case support portion 12 may be formed so as to be recessed from the thickness direction of the case 20, i.e., the outer surface facing the device thickness direction D1.

[0063] Furthermore, the guide roller 30 is not limited to a sprocket as described above, but may be, for example, a pulley or the like, as long as it can guide the adhesive tape T into the guide path 21.

[0064] Furthermore, the installation position of the auxiliary cutter 5 on the base body 1 is not particularly limited, and it can be installed in various positions that allow it to engage with the case support part 12. As an example, as shown in Figure 11, the auxiliary cutter 5 may be installed so that at least a portion of the blade body 5b of the auxiliary cutter 5 is located within the relief space 22 of the sealer body 2. Furthermore, the plate-like members 10 that make up the base body 1 may have slit-shaped auxiliary cutter grooves 10c formed from the front and / or rear end surfaces, and the auxiliary cutter 5 may be installed between the plate-like members 10 so that at least a portion of the blade body 5b is located within the auxiliary cutter grooves 10c.
