[0120] In addition, for the convenience of explanation, in each drawing, the upper side in the drawing is referred to as "up" or "above", the lower side is referred to as "down" or "below", the right side is referred to as "right", and the left side is referred to as "left".

[0121] In addition, in the present specification, "parallel" includes not only the case where two lines or surfaces are completely parallel, but also the case where the inclination is within ±5°. In addition, in the present specification, "orthogonal" includes not only the case where two lines or surfaces are completely orthogonal, that is, the case where the angle formed by the two lines or surfaces is 90°, but also the case where it is 85° or more and less than 90°, and the case where it is more than 90° and 95° or less.

[0122] The adhesive tape dispenser 1 shown in each drawing is a portable device, and is a device that feeds and adheres the adhesive tape 103 to an object by supplying water (liquid) to the adhesive tape 103 of the adhesive tape roll body 101 installed in the installation portion 11.

[0123] Compared to a stationary type, the adhesive tape dispenser 1 is small in size and light in weight, and can be held to perform work, is easy to operate, and can be carried.

[0124] In addition, the adhesive tape dispenser 1 is used, for example, in the adhesion of the adhesive tape 103 in the packaging of products and the like, and in the covering of a box (for example, a carton) in which products are loaded and the like.

[0125] In addition, as shown in Figure 4 the adhesive tape roll body 101 has the adhesive tape 103 having a base material and an adhesive (adhesion agent) that exhibits adhesion (adhesion property) when wetted with water (liquid), and the core material 102, and is formed by winding the adhesive tape 103 on the core material 102. As the adhesive, as long as it exhibits adhesion when wetted with water (liquid), it is not particularly limited, and for example, glue and the like can be cited. That is, as the adhesive tape 103, for example, paper tape, water tape, and the like can be cited.

[0126] In addition, the width of the adhesive tape 103 is 50 mm in the present embodiment, but is not limited thereto, and for example, can be 63 mm, or other widths.

[0127] As shown in Figures 1-7As shown, the adhesive tape dispenser 1 has a box-shaped housing 2, a handle 12, a blade mechanism (cutting mechanism) 3 that cuts the adhesive tape 103, a mounting portion 11 that mounts the adhesive tape roll body 101, an adhesive tape feeding mechanism 4 that feeds the adhesive tape 103 of the mounted adhesive tape roll body 101, a rod pushing mechanism 5, a tension roller mechanism 6, an adhesive tape cover 9 that covers the adhesive tape roll body 101 mounted to the mounting portion 11, and a water supply device (liquid supply device) 70 that is detachable with respect to the housing 2 (box type). Also, the adhesive tape feeding mechanism 4, the rod pushing mechanism 5, the tension roller mechanism 6, and the like are housed in the housing 2.

[0128] In addition, the handle 12 is fixed to the upper portion of the housing 2, and an operator can hold the adhesive tape dispenser 1 by gripping the handle 12.

[0129] Next, the mounting portion 11 will be described. Figures 1-7 、 Figure 10 The mounting portion 11 shown is a device (mechanism) that mounts the adhesive tape roll body 101. As described above, the mounting portion 11 is a device for the adhesive tape 103 having a width of 50 mm, but is not limited thereto.

[0130] In addition, the mounting portion 11 is provided to the housing 2. In addition, the mounting portion 11 is disposed to the rear (right side in FIG. 1) of the housing 2. Figure 1

[0131] In addition, the mounting portion 11 has a mounting portion main body 111 and a pressing member (pressing portion) 112 that is detachable with respect to the mounting portion main body 111.

[0132] In addition, the mounting portion main body 111 is in a cylindrical shape, and enables the core material 102 of the adhesive tape roll body 101 to be mounted to the outer peripheral portion of the mounting portion main body 111. That is, when the adhesive tape roll body 101 is mounted to the mounting portion 11, the mounting portion main body 111 is inserted into the core material 102. In a state in which the core material 102 of the adhesive tape roll body 101 is mounted to the outer peripheral portion of the mounting portion main body 111, the core material 102 is rotatable with respect to the mounting portion main body 111 (mounting portion 11). In addition, the mounting portion main body 111 is detachable with respect to the housing 2 in the present embodiment.

[0133] In addition, the pressing member 112 is a member that is mounted to the top end portion of the mounting portion main body 111 in a detachable manner. In this case, the pressing member 112 mounts the core material 102 of the adhesive tape roll body 101 to the outer peripheral portion of the mounting portion main body 111, and mounts the adhesive tape cover 9 to cover the adhesive tape roll body 101 in a state of being mounted to the housing 2, from the outside of the adhesive tape cover 9 to the top end portion of the mounting portion main body 111. Thereby, it is possible to prevent the adhesive tape roll body 101 from being detached or deviated from the mounting portion 11, and in addition, it is possible to prevent the adhesive tape cover 9 from being detached from the housing 2. ​

[0134] Furthermore, in this embodiment, the mounting part 11 (mounting part body 111) is fixed to the outer casing 2 and does not rotate relative to the outer casing 2, but it is not limited to this. For example, the mounting part 11 can be rotated relative to the outer casing 2. In this case, the core material 102 of the adhesive tape roll 101 can be kept from rotating relative to the mounting part 11 (mounting part body 111).

[0135] Next, the adhesive tape cover 9 will be explained.

[0136] Figures 1-3 , Figure 5 , Figure 6 The adhesive tape cover 9 shown is a component (structure) that covers the adhesive tape roll 101 installed on the mounting part 11.

[0137] Additionally, the adhesive tape cover 9 is provided on the housing 2. Furthermore, the adhesive tape cover 9 is positioned at the rear of the housing 2. Figure 1 The position corresponding to the mounting part 11 (the adhesive tape roll 101 mounted on the mounting part 11) is on the right side of the housing 2. Furthermore, the adhesive tape cover 9 is detachable from the housing 2 in this embodiment.

[0138] Furthermore, the adhesive tape cover 9 is cylindrical. Additionally, the adhesive tape cover 9 forms an annular shape in which the area of ​​the opening 91 on the top side is smaller than that on the base side, and the mounting part 11 is disposed at the position of the opening 91 in this annular part.

[0139] The adhesive tape cover 9 can suppress the radial diffusion of the adhesive tape 103 of the adhesive tape winding body 101 mounted on the mounting part 11 towards the adhesive tape winding body 101, or towards the central axis of the adhesive tape winding body 101. That is, the adhesive tape 103 is kept in a proper state by the adhesive tape cover 9.

[0140] Next, the blade mechanism 3 will be explained.

[0141] Figures 24-28 The blade mechanism 3 shown is a mechanism (device) for cutting (cutting) adhesive tape 103.

[0142] Furthermore, the blade mechanism 3 is disposed on the housing 2. Additionally, the blade mechanism 3 is positioned at the front of the housing 2. Figure 1 (Left side of the image). In addition, the blade mechanism 3 in this embodiment can be detached from the housing 2 (box type). As a result, the blade 31 of the blade mechanism 3 can be easily and quickly replaced.

[0143] Further, the blade mechanism 3 has a blade 31 that cuts the adhesive tape 103, a housing 32, and a reversing spring 35 as a force applying member that applies force in both directions. Further, the housing 32 has a support member 33 and a shutter 34 that is provided so as to be displaceable (movable) with respect to the support member 33, and the blade 31 is supported by the support member 33. Further, in the present embodiment, the blade 31 is provided so as to be movable in the up-and-down direction with respect to the support member 33. Further, in the present embodiment, the blade 31 is adhered (bonded) to one face of the support member 33 by a pair of double-sided tapes 36.

[0144] Further, the support member 33 has mounting portions 331 and 332 provided at a position on the upper side thereof and mounting portions 333 and 334 provided at a position on the lower side thereof. The blade mechanism 3 is detachably mounted to the front of the housing 2 by the mounting portions 331 to 334.

[0145] Further, the blade mechanism 3 can adopt a state in which the blade 31 is housed in the housing 32 and a state in which the blade 31 protrudes outward from the housing 32. However, in the present embodiment, one face of the blade 31 is exposed to the outside from the housing 32. Also, the blade mechanism 3, in a state in which it is mounted to the housing 2, either houses the blade 31 in a structure composed of the housing 2 and the housing 32 or causes the blade 31 to protrude outward. In the following, this is also referred to simply as "housing the blade 31" or "causing the blade 31 to protrude outward". Further, the "state in which the blade 31 is housed" is referred to simply as the "housing state", and the "state in which the blade 31 protrudes outward" is referred to simply as the "protruding state (usable state)".

[0146] If described specifically, the shutter 34 is provided on the opposite face (the other face) of the support member 33 from the face (one face) on which the blade 31 is provided, and is provided so as to be movable in the up-and-down direction with respect to the support member 33. Thus, the blade mechanism 3 can adopt the state in which the blade 31 is housed (not protruding outward) as shown in Figs. 1 and 2 and the state in which the blade 31 protrudes outward as shown in Figs. 3 and 4. Figure 24 and Figure 25 and the state in which the blade 31 protrudes outward as shown in Figs. 3 and 4. Figure 26 and Figure 27

[0147] Further, the mounting portion 351 at which one end portion of the reversing spring 35 is provided is mounted to a position slightly offset from the central portion of the support member 33, and the mounting portion 352 at which the other end portion is provided is mounted to the central portion of the shutter 34. Also, the reversing spring 35 applies force to the shutter 34 with respect to the support member 33. Specifically, the reversing spring 35 can selectively apply force to the shutter 34 in the direction in which the shutter 34 is closed (the direction in which the blade 31 is housed), that is, the lower side, and in the direction in which the shutter 34 is opened (the direction in which the blade 31 protrudes outward), that is, the upper side.

[0148] That is, in the present embodiment, the blade mechanism 3 is configured so that the blade 31 is housed in the housing 32 in the state in which the blade mechanism 3 is mounted to the housing 2, and the blade 31 protrudes outward from the housing 32 in the state in which the blade mechanism 3 is mounted to the housing 2. Figure 24 ​and Figure 25 In the housed state shown, the flip spring 35 exerts force to the gate 34 to the lower side relative to the support member 33 by its elastic force (restoring force). Thus, it is possible to prevent the gate 34 from being inadvertently opened. In addition, it becomes safe because it becomes the housed state.

[0149] On the other hand, in the projected state shown, the flip spring 35 exerts force to the gate 34 to the upper side relative to the support member 33 by its elastic force (restoring force). Thus, it is possible to prevent the gate 34 from being inadvertently closed. In addition, it is possible to cut the adhesive tape 103 with the blade 31 because it becomes the projected state. Figure 26 and Figure 27 In the housed state shown, the flip spring 35 exerts force to the gate 34 to the lower side relative to the support member 33 by its elastic force (restoring force). Thus, it is possible to prevent the gate 34 from being inadvertently opened. In addition, it becomes safe because it becomes the housed state.

[0150] In addition, in the housed state, when the gate 34 is moved to the upper side relative to the support member 33 against the force of the flip spring 35, the gate 34 is opened to become the projected state.

[0151] In addition, in the projected state, when the gate 34 is moved to the lower side relative to the support member 33 against the force of the flip spring 35, the gate 34 is closed to become the housed state.

[0152] Next, the water supply device (liquid supply device) 70 will be described.

[0153] Figures 18-23 The water supply device (liquid supply device) 70 shown is a device (mechanism) that stores water (liquid) and supplies the liquid to the adhesive tape 103.

[0154] In addition, the water supply device 70 is provided to the housing 2. In addition, the water supply device 70 is disposed to the front (left side in FIG. 1) and lower portion of the housing 2. In addition, the water supply device 70 is detachable (cassette type) with respect to the housing 2 in this embodiment. Thus, it is possible to easily and quickly perform storage of water with respect to the water supply tank 7, cleaning of the water supply tank 7, and the like. Figure 1 In addition, the water supply device 70 has the water supply tank 7 and the water absorbing roller 8.

[0155] In addition, the water supply tank 7 has a tank main body (housing) 71 that can store water (liquid) and a lid 72 that can be detached to a hole 711 of the tank main body 71.

[0156] In addition, the water absorbing roller 8 is provided inside the tank main body 71 in a rotatable manner. In addition, a part of the water absorbing roller 8 is exposed (projected) to the outside from the tank main body 71. In addition, the water absorbing roller 8 is disposed to the downstream side of the rollers 44, 45 of the tape feeding mechanism 4.

[0157] In addition, the water absorbing roller 8 has a roller main body 81 and a sponge sheet 82 provided to the outer peripheral surface (surface) of the roller main body 81.

[0158] In addition, the water absorbing roller 8 has a roller main body 81 and a sponge sheet 82 provided to the outer peripheral surface (surface) of the roller main body 81.

[0159] Further, the roller main body 81 has two components, i.e., a first component (upper component) and a second component (lower component) in the present embodiment, and is configured by components joined by these. Further, the roller main body 81 is a hollow component, and has a plurality of holes that communicate the inside and outside of the roller main body 81 in a portion where the sponge sheet 82 is not provided.

[0160] Further, the sponge sheet 82 is a sheet configured by a sponge (e.g., polyurethane or the like), and is an example of a component that can absorb water (liquid) (has liquid absorbency) and has elasticity (softness).

[0161] Further, the tank main body 71 is configured to be able to store water (liquid) inside thereof. Further, the tank main body 71 has two components, i.e., a first case (upper case) and a second case (lower case) in the present embodiment, and is configured by components joined by these with double-sided tape (adhesive) 73. Further, the shape of the tank main body 71 is not particularly limited, and in the present embodiment, a flat shape in which the thickness in the vertical direction of the tank main body 71 is thinned is formed in a state in which the water supply device 70 is installed to the housing 2.

[0162] Further, a hole 711 that communicates the inside and outside of the tank main body 71 is formed on the upper side of the tank main body 71. Further, the shape of the hole 711 in plan view is formed in a circular shape.

[0163] Further, the lid 72 is detachable with respect to the hole 711, and in a state in which the lid 72 is detached from the hole 711, water can be injected into the tank main body 71 from the hole 711, and in a state in which the lid 72 is installed to the hole 711, leakage of water inside the tank main body 71 from the hole 711 can be prevented.

[0164] Further, a hole 712 that communicates the inside and outside of the tank main body 71 is formed on the upper side of the tank main body 71. Further, the shape of the hole 712 in plan view is formed in a shape that corresponds to the shape of the water absorbing roller 8 in plan view.

[0165] Further, a portion of the upper side of the water absorbing roller 8 is exposed (protrudes) to the outside of the tank main body 71 from the hole 712.

[0166] Further, a prescribed portion of the tank main body 71 has light transmissivity in the present embodiment. That is, the tank main body 71 is transparent or translucent. Thereby, the amount or state of water inside the tank main body 71 can be visually confirmed.

[0167] Further, an index 713 that indicates the maximum amount (storage amount) is provided on the outside (surface) of the tank main body 71, and it is ensured that even if the water supply tank 7 (tank main body 71) is tilted by a prescribed angle (90° in the present embodiment) from the horizontal posture (refer to FIG. 6), the index 713 is visible. Figure 23) and does not cause the water stored inside to leak out to the outside. In addition, the index 713 is formed of a straight line in this embodiment.

[0168] That is, if the water supply tank 7 is in a horizontal posture, the position of the water surface of the water stored inside is the same as the position of the index 713, or the position of the water surface is on the lower side in the vertical direction of the index 713, even if the water supply tank 7 is tilted to 90° in the direction of deviation from the horizontal posture (refer to Figure 23 ), the stored water does not leak out to the outside.

[0169] In addition, the word "MAX" is provided in the vicinity of this index 713. Thus, the operator can grasp that the water can be stored in the water supply tank 7 up to the position of the index 713.

[0170] In addition, in the water supply device 70, the water stored in the water supply tank 7 is absorbed (sucked) by the sponge sheet 82 of the water absorbing roller 8, and the water is applied to the adhesive of the adhesive tape 103.

[0171] Next, the tape feeding mechanism 4 will be described.

[0172] Figures 1-13 The tape feeding mechanism 4 illustrated in the drawing has an operation portion 41 that can be rotated, and the adhesive tape 103 can be fed by manually rotating the operation portion 41. By having this tape feeding mechanism 4, the operability when feeding the adhesive tape 103 is excellent. In addition, since the tape feeding mechanism 4 operates by hand, a battery or a power source is not required.

[0173] In addition, a part (the upper part in Figure 8 ) of the operation portion 41 is exposed (protrudes) to the outside from the housing 2. The part of the operation portion 41 that is exposed (protrudes) to the outside is an exposed portion (protruding portion) 42. The operator operates (rotates) the exposed portion 42 in the operation portion 41 with a finger.

[0174] In addition, the outer shape of the operation portion 41 in a side view (when viewed from a direction orthogonal to the paper surface with respect to Figure 6 ) is circular. In addition, a plurality of ribs 411 are formed on the outer peripheral surface of the operation portion 41. By the ribs 411, when the operation of rotating the operation portion 41 with a finger is performed, the finger can be prevented from slipping.

[0175] In addition, the tape feeding mechanism 4 has a reverse rotation prevention mechanism 43 that allows the operation portion 41 to be rotated in one direction (the counterclockwise direction in Figure 8 ), and prevents the operation portion 41 from being rotated in the other direction (the clockwise direction in Figure 8 ).

[0176] Additionally, the reverse rotation preventing mechanism 43 has a gear 432 disposed on the operating part 41 and allows the gear 432 to rotate in one direction ( Figure 8 Rotate counterclockwise (in the middle) to prevent it from rotating in the other direction ( Figure 8 The ratchet mechanism 431 of the brake element 433 rotates clockwise.

[0177] In addition, the tape feeding mechanism 4 includes: a roller (first roller) 44 and a roller (second roller) 45, which hold the adhesive tape 103; and a power transmission mechanism 46, which transmits the rotational force of the operating part 41 to the roller 44.

[0178] Furthermore, in this embodiment, the portion of one of the rollers 44 and 45 that contacts the adhesive tape 103 is elastic. That is, roller 44 is a rubber (elastic) roller. Therefore, when the adhesive tape 103 is held by rollers 44 and 45, roller 44 can undergo elastic deformation, reliably holding the adhesive tape 103 and preventing the adhesive tape 103 from sliding relative to rollers 44 and 45.

[0179] Furthermore, the power transmission mechanism 46 includes: a gear (first gear) 461 disposed on the operating part 41; a gear (second gear) 462 meshing with gear 461; a gear (third gear) 463 meshing with gear 462; and a gear (fourth gear) 464 meshing with gear 463 and disposed on the roller 44. In this embodiment, the power transmission mechanism 46 has four gears, but is not limited to this; any even number of gears is acceptable, such as two, six, or eight.

[0180] Furthermore, the surface (top) on one side of the handle 12 of the outer casing 2, that is, the area near the operating part 41, is the surface that the operator's fingers touch and slide when operating (rotating) the operating part 41 of the tape feed mechanism 4 (the surface for sliding fingers). This surface is called the operating surface (operating plane) 21. In addition, the operating surface 21 is a plane.

[0181] Furthermore, when the tape feeding mechanism 4 rotates the operating part 41 in the same direction as the movement of the adhesive tape 103 when it is fed from the tape dispenser 1 (housing 2), that is, when the operating part 41 is rotated in the same direction as the movement of the outer peripheral surface of the exposed portion 42, that is, when the operating part 41 is rotated in the same direction as the movement of the adhesive tape 103 when it is fed from the tape dispenser 1 (housing 2), the operating part 41 is rotated towards ( Figure 8 (in the counterclockwise direction) Figure 9 When the operating part 41 is rotated clockwise, the adhesive tape 103 is fed from the tape dispenser 1. In this case, the operator places their finger along the operating surface 21, that is, within the surface of the operating surface 21 (parallel to the operating surface 21), towards... Figure 8 and Figure 9 Move (operation) in the direction of arrow 'a'.

[0182] In addition, in a case where the tape feeding mechanism 4 is rotated in a manner that the moving direction of the outer peripheral surface of the exposed portion 42 is opposite to the moving direction of the adhesive tape 103 when the adhesive tape 103 is fed from the tape dispenser 1, that is, in a case where the operation portion 41 is rotated in a clockwise direction in the drawing (in a counterclockwise direction in the drawing), the rotation of the operation portion 41 is prevented by the gear 432 of the reverse rotation prevention mechanism 43 being engaged with the stopper 433. In this case, the operator moves (operates) the finger along the operation surface 21, that is, in a direction of an arrow b in the drawing (parallel to the operation surface 21) within the surface of the operation surface 21. Figure 8 Figure 9 Figure 8 Figure 9

[0183] Next, the tension roller mechanism 6 will be described.

[0184] Figure 6 Figure 7 Figure 10 Figures 14-17 The tension roller mechanism 6 shown in FIG. 8 is a mechanism (device) that pushes the adhesive tape 103 against the water-absorbing roller 8 that has absorbed water (water-absorbed) so as to apply water (liquid) to the adhesive of the adhesive tape 103 fed by the tape feeding mechanism 4.

[0185] In addition, the tension roller mechanism 6 is movably provided to the housing 2. In addition, the tension roller mechanism 6 is disposed on the upper side of the water supply device 70 on the left side in the drawing (front side of the housing 2). Figure 1

[0186] In addition, the tension roller mechanism 6 has a tension roller 61. The tension roller 61 is disposed on the downstream side of the rollers 44, 45 of the tape feeding mechanism 4. Further, the tension roller 61 is displaced from the water-absorbing roller 8 or pushed against the water-absorbing roller 8 by the lever pushing mechanism 5. In other words, the tension roller mechanism 6 can adopt a separated state shown in FIG. 9 in which the tension roller 61 is separated from the water-absorbing roller 8 and a pushed state (pressed state) shown in FIG. 10 in which the tension roller 61 is pushed against the water-absorbing roller 8, that is, a clamped state in which the adhesive tape 103 is clamped by the tension roller 61 and the water-absorbing roller 8. Figure 15 Figure 14 Figure 16 Figure 17

[0187] Next, the lever pushing mechanism 5 will be described.

[0188] Figures 1-6 Figure 14 Figure 15 Figure 31 Figure 32 ​​​​​​​​​​​​​​​​The illustrated lever pushing mechanism 5 is a mechanism (device) that displaces the tension roller mechanism 6, the power transmission mechanism 46 of the tape feeding mechanism 4, and the roller 44, and the like. The lever pushing mechanism 5 is provided to the housing 2.

[0189] In addition, the lever pushing mechanism 5 has an operation lever (operation portion) 51, a power transmission mechanism 52 that finally transmits displacement of the operation lever 51 to the tension roller 61 and the roller 44, and a reversing spring 53 that is a biasing member capable of biasing in two directions. In addition, the power transmission mechanism 52 has a link mechanism, a cam mechanism, or the like.

[0190] In addition, the operation lever 51 is displaceably provided to an upper portion of the housing 2, and in the present embodiment, is rotatably provided with one end portion of the operation lever 51 as a center (rotation center). That is, the operation lever 51 is capable of displacement to a state in which the operation lever 51 stands up (standing-up state) and a state in which the operation lever 51 is tilted down (tilted-down state) by operation of an operator. Hereinafter, the state in which the operation lever 51 stands up is also referred to as "standing-up state of the operation lever 51", and the state in which the operation lever 51 is tilted down is also referred to as "tilted-down state of the operation lever 51".

[0191] In addition, the reversing spring 53 biases the operation lever 51 and the power transmission mechanism 52 with respect to the housing 2. Specifically, the reversing spring 53 is capable of selectively biasing the operation lever 51 and the power transmission mechanism 52 in a direction in which the operation lever 51 stands up and a direction in which the operation lever 51 is tilted down. Thereby, the operation lever 51 and the power transmission mechanism 52 are maintained in the standing-up state of the operation lever 51 by the elastic force (restoring force) of the reversing spring 53, and are maintained in the tilted-down state of the operation lever 51 by the elastic force (restoring force) of the reversing spring 53.

[0192] In addition, in the illustrated standing-up state of the operation lever 51, the tension roller 61 of the tension roller mechanism 6 is separated from the suction roller 8 of the water supply device 70. Figure 15 In the illustrated standing-up state of the operation lever 51, the tension roller 61 of the tension roller mechanism 6 is separated from the suction roller 8 of the water supply device 70.

[0193] Thereby, it is possible to arrange the adhesive tape 103 between the tension roller 61 and the suction roller 8.

[0194] In addition, in the illustrated standing-up state of the operation lever 51, the tension roller 61 of the tension roller mechanism 6 is separated from the suction roller 8 of the water supply device 70. Figure 15 In the illustrated standing-up state of the operation lever 51, the tension roller 61 of the tension roller mechanism 6 is separated from the suction roller 8 of the water supply device 70.

[0195] Thereby, it is possible to arrange the adhesive tape 103 between the tension roller 61 and the suction roller 8.

[0196] In addition, in the illustrated standing-up state of the operation lever 51, the tension roller 61 of the tension roller mechanism 6 is separated from the suction roller 8 of the water supply device 70. Figure 14 In the illustrated standing-up state of the operation lever 51, the tension roller 61 of the tension roller mechanism 6 is separated from the suction roller 8 of the water supply device 70.

[0197] Thus, the adhesive tape 103 can be held by the tension roller 61 and the water absorption roller 8.

[0198] In addition, Figure 14 With the operating lever 51 tilted, the roller 44 of the tape feeding mechanism 4 pushes the roller 45.

[0199] Thus, the adhesive tape 103 can be clamped by rollers 44 and 45.

[0200] Thus, the lever-pushing mechanism 5 can be used to achieve the following states: tension roller 61 separated from water-absorbing roller 8, roller 44 separated from roller 45, tension roller 61 pushing against water-absorbing roller 8 (the adhesive tape 103 is held between tension roller 61 and water-absorbing roller 8), and roller 44 pushing against roller 45 (the adhesive tape 103 is held between roller 44 and roller 45).

[0201] Next, an example of using the tape dispenser 1 (usage method) will be explained.

[0202] <Preparation Process> (1)

[0204] like Figure 29 , Figure 30 As shown, the blade mechanism 3 is mounted on the housing 2 via mounting parts 331 to 334. (2)

[0206] like Figure 4 and Figure 5 As shown, the core material 102 of the adhesive tape roll 101 is installed on the mounting body 111.

[0207] Next, with the operating lever 51 in the upright position, the adhesive tape 103 of the adhesive tape winding body 101 is positioned between rollers 44 and 45, and between tension roller 61 and absorbent roller 8, with the top end of the adhesive tape 103 extending from the front of the tape distributor 1. Figure 5 (The left side of the middle) protrudes outward.

[0208] Next, as Figure 5 As shown, the adhesive tape cover 9 is installed on the mounting body 111, and the pressing component 112 is installed on the mounting body 111. (3)

[0210] like Figure 31 and Figure 32 As shown, water is injected into the water supply tank 7 of the water supply device 70, and the water supply device 70 is installed on the outer casing 2. In addition, the amount of water stored in the water supply tank 7 is maximized until the water level is at the position of index 713.

[0211] Furthermore, the order of the steps in (1), (2), and (3) can be arbitrary. (4)

[0213] The operation lever 51 is brought to the pouring state. Thus, the adhesive tape 103 is gripped by the rollers 44 and 45, and the adhesive tape 103 is gripped by the tension roller 61 and the water absorbing roller 8.

[0214] Further, in the case where the order of the processes of (1), (2), and (3) is changed, the process of (4) can be after the processes of (2) and (3) as long as the process of (4) is after the process of (2).

[0215] <Usage Process>

[0216] As shown in FIG. 1, the adhesive tape dispenser 1 is placed on a carton 201 as an example of an object. Figure 33

[0217] Then, in a state where the adhesive tape 103 is gripped by the rollers 44 and 45 and the adhesive tape 103 is gripped by the tension roller 61 and the water absorbing roller 8, a finger is moved in the direction of the arrow a in FIG. 4, and the operation portion 41 is rotated in the counterclockwise direction in FIG. 4. Thus, the gear 432 of the operation portion 41 is not caught by the stopper 433, and the operation portion 41 is rotated. Thus, the gears 461, 462, 463, and 464 are sequentially rotated, the roller 44 is rotated in the clockwise direction in FIG. 4, and the roller 45 is rotated in the counterclockwise direction in FIG. 4 together with the roller 44 (see FIGS. 5 and 6). Thus, the adhesive tape 103 is moved to the left in FIGS. 5 and 6. Figure 8 Figure 8 Figure 8 Figure 8 Figure 8 Figure 9 Figure 8 Figure 33

[0218] Further, the adhesive tape 103 passes between the tension roller 61 and the water absorbing roller 8 that absorbs the water of the water tank 7, at this time, the adhesive of the adhesive tape 103 is coated with the water, and thus the adhesive exhibits adhesion. Further, the adhesive tape 103 is fed out from the front of the housing 2.

[0219] Then, as shown in FIGS. 7 and 8, the adhesive tape 103 is attached to a prescribed portion of the carton 201. Figure 33 Figure 34 Further, after the attachment of the adhesive tape 103 to the carton 201 is completed, the adhesive tape 103 is cut by the blade 31 of the blade mechanism 3 at a prescribed position. Thus, the operation of attaching the adhesive tape 103 to the carton 201 is completed.

[0220]

[0221] ​​​​​​​​​​​Further, the blade mechanism 3 can be in the protruding state in advance (preliminarily), or can be in the protruding state before the adhesive tape 103 is cut.

[0222] On the other hand, if the finger is moved in the direction of the arrow b in FIG. 4B instead of the direction of the arrow a in FIG. 4A, and the operation portion 41 is rotated in the clockwise direction in FIG. 4B, the gear 432 provided to the operation portion 41 is caught by the stopper 433, and the rotation of the operation portion 41 is stopped. Figure 8 Figure 8 Figure 8

[0223] Thus, the adhesive tape 103 wetted by water can be prevented from being moved in the opposite direction and stuck inside the tape dispenser 1.

[0224] As described above, according to the tape dispenser 1, the operability when feeding the adhesive tape 103 is excellent. Thus, the adhesive tape 103 can be easily and quickly stuck to an object.

[0225] That is, since the tape feeding mechanism 4 is provided, when the work of sticking the adhesive tape 103 to an object is performed, the adhesive tape 103 does not need to be held by a finger, and thus, the finger of the worker can be prevented from being wetted by water adhered to the adhesive tape 103.

[0226] Further, since the moving direction of the outer circumferential surface of the exposed portion 42 when the adhesive tape 103 is fed and the moving direction of the adhesive tape 103 are on the same side, the operation direction of the operation portion 41 when the adhesive tape 103 is fed can be grasped in perception, and thus, the adhesive tape 103 can be easily and quickly fed.

[0227] Further, since the reverse rotation stopping mechanism 43 is provided, the adhesive tape 103 wetted by water can be prevented from being moved in the opposite direction and stuck inside the tape dispenser 1.

[0228] The tape dispenser of the present application has been described above according to the embodiment of the drawings, but the present application is not limited thereto, and the structure of each portion can be replaced by any structure having the same function. Further, any other structure can be added. Further, the present application can be a combination of any two or more structures (features) in the above-described embodiments.

[0229] Further, in the above-described embodiment, the tape dispenser (mounting portion) corresponds to one adhesive tape (tape) having a width of 50 mm, but in the present application, the width of the adhesive tape that can be corresponded to is not limited thereto, and for example, can be 63 mm, or can be other widths.

[0230] ​​​In addition, in the embodiment, the width of the corresponding adhesive tape is one, but in the present application, the width of the corresponding adhesive tape is not limited to this, and can be two or more, for example. Specifically, the tape dispenser can be configured to correspond to two types of adhesive tapes, one having a width of 50 mm and the other having a width of 63 mm, for example.
