Summary of the Invention

Problems to be Solved by the Invention

[0004] The label printing device winds up the backing sheet from which the printed label paper has been peeled by a backing sheet winding roller. The user has a problem that it is necessary to wind the backing sheet around the backing sheet winding roller when replacing the label roll, which is time-consuming.

[0005] An object of the present invention is to provide a label affixing device that can easily collect the release material after peeling the label and can be miniaturized.

Means for Solving the Problems

[0006] According to one aspect of the present invention, there is provided a label affixing device including a mounting portion on which a tape is mounted, the tape including a label, an adhesive surface for attaching the label to an adherend, and a release sheet covering the adhesive surface on the side opposite to the label; a printing portion for printing on the label of the tape mounted on the mounting portion; a peeling mechanism for peeling the label from the release sheet of the tape printed by the printing portion and discharging the release sheet; an affixing portion for affixing the label peeled from the release sheet by the peeling mechanism to the adherend; and a housing portion provided in a housing for accommodating the release sheet discharged by the peeling mechanism.

[0007] By providing the housing portion in the housing, the label affixing device can easily collect the release sheet remaining after peeling the label from the tape, and can reduce the size of the device configuration.

[0008] In this aspect, the peeling mechanism may include a peeling claw for peeling the label printed by the printing portion from the release sheet, a peeling roller for feeding the release sheet after the label is peeled by the peeling claw to the housing portion, and a driving portion for driving the peeling roller. By pulling out the release sheet with the peeling roller and feeding it to the peeling claw, the peeling mechanism can more reliably peel the tape, and by feeding the release sheet after peeling toward the housing portion, the release sheet can be more reliably accommodated in the housing portion.

[0009] In this aspect, a housing region, which is a region where the housing portion is provided in the housing, may communicate with a mounting region where the mounting portion is provided in the housing. Since the label affixing device has the housing region and the mounting region communicating with each other, and uses a partial region of the mounting portion communicating with the housing portion as the housing portion to increase the capacity of the housing portion, the release sheet after label peeling can be easily collected. Also, since the region of the wall portion provided when partitioning the housing portion and the mounting portion can be effectively used, the label affixing device can reduce the size of the device configuration.

[0010] In this aspect, within the housing, the storage area is provided above the mounting area, the tape is stored in a cassette that can be mounted on the mounting portion, and the release material stored in the storage portion may be able to enter the mounting area. The label applicator can also store the release material stored in the storage portion in a partial area of the mounting portion through the communication portion with the mounting portion. Therefore, by making the storage portion have a larger capacity, the label applicator can easily collect the release material after label peeling.

[0011] In this aspect, the tape is stored in a cassette that can be mounted on the mounting portion. The mounting portion opens to the housing in the attachment / detachment direction of the cassette. Within the housing, the storage portion is provided in the area between the mounting portion and the bottom wall of the housing and opens to the housing in the attachment / detachment direction to the mounting portion. A cassette cover that covers the opening of the storage portion and the opening of the mounting portion and can be opened and closed may be provided. The label applicator can use the empty space between the mounting portion of the cassette and the bottom wall of the housing within the housing as a storage portion for the release material. Therefore, since the label applicator can effectively utilize the space within the housing, the configuration of the apparatus can be miniaturized.

[0012] This aspect includes a transport cover that can be opened and closed between a state where the transport path for transporting the release material, from which the label has been peeled by the peeling claw, to the storage portion and the peeling mechanism are exposed and a state where they are not exposed. The peeling roller may release the holding of the release material at the nip portion as the transport cover is opened. When the transport cover is opened for maintenance or the like, the holding of the release material by the peeling roller is mechanically released, so that the user can easily take out the release material.

[0013] In this aspect, the peeling mechanism includes a guide roller for guiding the tape to the peeling claw. The guide roller may release the holding of the tape at the nip portion in conjunction with the opening of the transport cover. When the transport cover is opened for maintenance or the like, the holding of the tape by the guide roller is released by interlocking, so that the user can easily take out the tape and the release material.

[0014] In this aspect, at the end of the peeling material in the conveying direction, it may be provided with an inclined portion whose cross-section is inclined in an arc shape and guides the peeling material sent out from the peeling roller toward the inside of the accommodating portion. The inclined portion can guide the peeling material into the accommodating portion while winding the peeling material and accommodating it in the accommodating portion.

[0015] In this aspect, at the end of the peeling material in the conveying direction, it may be provided with a roller that guides the peeling material sent out from the peeling roller toward the inside of the accommodating portion. The roller can guide the peeling material into the accommodating portion while winding the peeling material and accommodating it in the accommodating portion.

[0016] In this aspect, the accommodating portion may be an empty chamber with an opening for the accommodating port of the peeling material and surrounded by a wall surface around it. The accommodating portion functions as an empty chamber for storing the peeling material sent out from the peeling mechanism. For example, a winding roller for winding the peeling material is not installed. Therefore, the label affixing device can achieve miniaturization of the device configuration.

[0017] In this aspect, it may be provided between the printing portion and the peeling mechanism in the conveying direction of the tape and be provided with a cutting portion for cutting the tape. By the cutting portion cutting the tape, the tape before peeling and the peeling material after peeling on the downstream side of the cutting portion are separated from the original tape. Therefore, it is easy for the user to collect the peeling material to be accommodated in the accommodating portion.

[0018] In this aspect, it may be provided on the downstream side of the peeling roller in the conveying direction of the peeling material and be provided with a peeling sensor for detecting the presence or absence of the peeling material. By detecting the presence or absence of the peeling material on the downstream side of the peeling roller by the peeling sensor, it is possible to confirm whether the peeling material is properly sent to the conveying path toward the accommodating portion.

[0019] This aspect includes a reception unit that receives an input of an instruction to replace the tape. When the reception unit receives the input of the instruction to replace the tape, the cutting unit may cut the tape. When the user inputs an instruction to replace the tape during tape replacement, the tape and the release material after peeling, which are downstream of the cutting unit before peeling of the label, are separated from the original tape. Therefore, it is easy for the user to collect the release material to be stored in the storage unit.

[0020] In this aspect, after the cutting unit cuts the tape, the driving unit of the conveying mechanism may drive the peeling roller for a predetermined amount corresponding to the length required for the release material and the rear end portion of the tape cut by the cutting unit to pass through the peeling roller along the conveying direction and then stop. When the user inputs an instruction to replace the tape during tape replacement, the tape before label peeling and the release material after peeling separated by the cutting unit are conveyed for a predetermined length, and the rear end is located downstream of the peeling roller. Therefore, it is easy for the user to collect the release material to be stored in the storage unit.

[0021] This aspect may include a display unit that displays a replacement permission notification for permitting the replacement of the tape after the driving unit stops driving the peeling roller. Immediately after the user inputs an instruction to replace the tape during tape replacement, the cutting unit, the peeling mechanism, etc. are driving, so if the user performs tape replacement, the tape may jam. By displaying a replacement permission notification on the display unit, it is possible to inform the user of the timing when the tape can be replaced.

[0022] This aspect includes a mounting sensor provided on the mounting unit to detect whether the tape is mounted. The display unit may continue to display the replacement permission notification when the mounting sensor detects that the tape is mounted on the mounting unit, or when the peeling sensor detects that the release material is on the conveying path. The display unit continues to display the replacement permission notification not only when the tape is removed from the mounting unit but also until the release material is collected from the storage unit. Therefore, the label affixing device can prevent the user from forgetting to collect the release material during tape replacement.

[0023] In this aspect, when the tape is replaced, the mounting sensor detects that the tape is in a mounted state both when the tape before replacement is mounted on the mounting portion and when the tape after replacement is mounted on the mounting portion. When the tape before replacement is removed from the mounting portion and the mounting sensor stops detecting the tape, and then the peeling sensor detects that the peeling material is on the conveyance path, the display unit may continue to display the replacement permission notification. Even if the user replaces the tape before taking out the peeling material, if the peeling material is taken out, the label affixing device can end the display of the replacement permission notification on the display unit.

[0024] This aspect is provided between the printing unit and the peeling mechanism in the conveyance direction of the tape, and includes a half-cutting unit that cuts a predetermined portion of the tape while leaving the peeling material to generate the label. The peeling material cut by the cutting unit and the peeling material on the downstream side of the conveyance direction from the rear end portion of the tape are accommodated in the accommodating portion without being cut from the rear end portion by the half-cutting unit. When the peeling material is taken out from the accommodating portion during tape replacement, the rear end portion is taken out from the conveyance path together with the peeling material, and the peeling sensor may stop detecting the peeling material. The peeling material discharged before tape replacement is accommodated in the accommodating portion in a connected state without being cut. Therefore, if the user takes out the peeling material from the accommodating portion, the rear end portion of the cut tape is also taken out from the conveyance path, and the label affixing device can end the display of the replacement permission notification on the display unit.

Embodiments for Carrying Out the Invention

[0026] An embodiment of the label winding device 1A embodying the present invention will be described with reference to the drawings. The drawings to be referred to are used to explain the technical features that the present invention can adopt, and the configuration of the described device etc. is not intended to be limited thereto, but is merely an illustrative example. The label winding device 1A is a device for generating a label 10A by printing on a tape 10 of a tape cassette TC, and winding and attaching the generated label 10A to a cable 19. Hereinafter, the lower left, upper right, upper left, lower right, upper, and lower parts of FIG. 1 are defined as the front, rear, left, right, upper, and lower parts of the label winding device 1A, respectively.

[0027] <Overview of the label winding device 1A> With reference to FIGS. 1 to 6, the overview of the label winding device 1A will be described. The label winding device 1A has a box-shaped housing 11. The housing 11 houses a frame 13 (see FIG. 4) composed of side plates 13A and 13B facing each other in the left-right direction, and a frame 14 (see FIG. 3). The frame 13 supports a transport mechanism 3A (first roller 301, second roller 302, third roller 303), a transmission part 3B, a peeling guide mechanism 4, an opening / closing member 5, an attaching mechanism 6, a holding member 7, etc. The frame 14 is provided behind the frame 13 and supports a printing part 2B and a cutting part 2C.

[0028] As shown in FIGS. 1 and 6, the bottom surface of the housing 11 forms an installation surface 110 that faces a table or the like when the housing 11 is placed on a table or the like. The installation surface 110 has a flat shape and extends horizontally. The label winding device 1A is used in a state where the housing 11 is installed on a table or the like by the installation surface 110.

[0029] As shown in FIG. 1, a tape storage section 2A, a printing section 2B, and a cutting section 2C are provided in a portion of the housing 11 on the rear side of the center in the front-rear direction. A tape cassette TC (see FIG. 6) is detachably stored in the tape storage section 2A. The tape cassette TC is a laminate type tape cassette. The second cover 122 is rotatably provided at the lower end of the housing 11. The rotation center 122C of the second cover 122 extends in the front-rear direction. The second cover 122 can open and close the tape storage section 2A and the paper discharge storage section 16. FIGS. 1 and 2 show the second cover 122 in an open state. The second cover 122 has a side wall portion 122R that covers the right side surface of the housing 11 when closed, and a top wall portion 122U that covers the upper surface of the housing 11 when closed, and is substantially L-shaped in a front view. When the second cover 122 is closed, the paper discharge storage section 16, the tape storage section 2A, the printing section 2B, and the cutting section 2C are covered by the second cover 122 and are not exposed. On the other hand, when the second cover 122 is in an open state, the paper discharge storage section 16, the tape storage section 2A, the printing section 2B, and the cutting section 2C are exposed. The opening on the right side surface side of the housing 11 formed when the second cover 122 is in an open state is referred to as a second opening 122A, and the opening on the upper surface side of the housing 11 is referred to as a third opening 122B. The second opening 122A opens to the right, and the third opening 122B opens upward. The tape cassette TC is detached from and attached to the tape storage section 2A through the second opening 122A in the open state of the second cover 122. The detachment and attachment direction of the tape cassette TC is the left-right direction.

[0030] The label 10A generated by printing on the tape 10 by the printing section 2B and cutting the tape 10 by the cutting section 2C is peeled off from the release material 10B by a peeling guide mechanism 4 (see FIGS. 5 and 6). The label 10A peeled off from the release material 10B passes through a passage area 300A in the housing 11 and is guided to a guide member 8A and an attaching mechanism 6. On the other hand, the release material 10B from which the label 10A has been peeled off passes through a passage area 300B in the housing 11 and is stored in a paper discharge storage section 16 provided in the upper part of the housing 11. The passage areas 300A and 300B are formed below the first cover 121 of the housing 11 (see FIG. 8).

[0031] As shown in FIGS. 1, 6, and 46, the paper discharge storage unit 16 is open on the right, upper, and front sides. The front open portion is closed by the first cover 121. The right and upper open portions are closed by the second cover 122. In the closed state of the second cover 122, the paper discharge storage unit 16 opens an accommodation port 16A through which the peeling material 10B passing through the passage region 300B (described later) enters the paper discharge storage unit 16. The accommodation port 16A extends long in the left-right direction. The accommodation port 16A is connected to the passage region 300B in the closed state of the first cover 121. A roller 16B is provided below the accommodation port 16A. The roller 16B is a cylindrical rotating body extending in the left-right direction. The roller 16B imparts roundness to the peeling material 10B entering the paper discharge storage unit 16 from the accommodation port 16A so that the peeling material 10B is likely to be rounded within the paper discharge storage unit 16.

[0032] As shown in FIGS. 6 and 46, the storage area 11A in the housing 11 where the paper discharge storage unit 16 is provided is located above the mounting area 11B where the tape storage unit 2A is provided in the housing 11. The storage area 11A and the mounting area 11B communicate with each other. That is, the paper discharge storage unit 16 and the tape storage unit 2A are not partitioned within the housing 11. Therefore, the peeling material 10B stored in the paper discharge storage unit 16 can also enter the mounting area 11B where the tape storage unit 2A is located. The second cover 122 opens both the paper discharge storage unit 16 and the tape storage unit 2A in the open state. The peeling material 10B stored in the paper discharge storage unit 16 and the tape storage unit 2A is taken out through the second opening 122A and the third opening 122B and discharged to the outside when replacing the tape cassette TC or the like.

[0033] As shown in FIGS. 1 and 2, the first cover 121 is rotatably provided in front of the tape storage unit 2A. The rotation center 121K (see FIG. 1) of the first cover 121 extends in the left-right direction. The first cover 121 opens and closes the peeling guide mechanism 4, the conveyance path R2 disposed in the passage area 300A, and the conveyance paths R3 and R4 disposed in the passage area 300B. More specifically, the first cover 121 opens and closes the peeling guide mechanism 4, a second roller 302 (described later) for conveying the label 10A along the conveyance path R2, and a third roller 303 (described later) for conveying the peeling material 10B and the tape 10 along the conveyance paths R3 and R4. As shown in FIG. 8, the conveyance path R2 is a path through which the label 10A peeled from the peeling material 10B by the peeling guide mechanism 4 is conveyed toward the guide member 8A and the sticking mechanism 6 housed in the front end portion of the housing 11. The conveyance path R3 is a path through which the peeling material 10B from which the label 10A has been peeled by the peeling guide mechanism 4 is conveyed toward the paper discharge storage unit 16 of the housing 11. As shown in FIG. 11, the conveyance path R4 is a path through which the tape 10 of the tape cassette TC is directly conveyed toward the paper discharge storage unit 16.

[0034] FIGS. 1 and 18 show the first cover 121 in a closed state. In this state, the peeling guide mechanism 4 and the conveyance paths R2 to R4 are covered by the first cover 121 and are not exposed. FIGS. 3 and 4 show the first cover 121 in an open state. In this state, the peeling guide mechanism 4 and the conveyance paths R2 to R4 are exposed. As shown in FIG. 4, the opening formed by the opening of the first cover 121 is referred to as the first opening 121S. The first opening 121S opens upward. The opening direction (upward) of the first opening 121S is different from the opening direction (rightward) of the second opening 122A (see FIGS. 1 and 2).

[0035] As shown in FIG. 46, when the first cover 121 is closed, a gap serving as a passage area 300B is formed between the front surface of the housing 11 above the peeling guide mechanism 4. The tip portion 121E, which is the end portion on the free end side of the first cover 121, covers the housing opening 16A of the paper discharge storage portion 16 from the front in the closed state of the first cover 121. The surface of the tip portion 121E facing the housing opening 16A side is inclined, and an inclined portion 121F is formed to guide the peeling material 10B passing through the passage area 300B into the housing opening 16A. The inclined portion 121F curves while maintaining a gap from the outer peripheral surface of the roller 16B. The inclined portion 121F guides the conveyance direction of the peeling material 10B conveyed obliquely upward and rearward along the conveyance path R4 from the peeling guide mechanism 4 to the rear.

[0036] The label 10A peeled from the peeling material 10B by the peeling guide mechanism 4 is wound around and attached to the cable 19 by the attaching mechanism 6. The third cover 123 is rotatably provided at the front end portion of the housing 11 and opens and closes the attaching mechanism 6. The rotation center 123C of the third cover 123 extends in the left - right direction. FIGS. 1 and 3 show the third cover 123 in the closed state. In this state, the attaching mechanism 6 is covered by the third cover 123 and is not exposed. FIG. 2 shows the third cover 123 in the open state. In this state, the attaching mechanism 6 is exposed. The opening formed by the opening of the third cover 123 is referred to as the third opening. The third opening opens upward. The opening direction (upward) of the first opening 121S and the opening direction (upward) of the third opening (see FIG. 2) coincide.

[0037] The fourth cover 124 is detachably provided on the side opposite to the second cover 122 with respect to the tape storage portion 2A. FIGS. 1 and 2 show the state in which the fourth cover 124 is attached. In this state, the drive unit 9B that drives the printing unit 2B and the cutting unit 2C is covered by the fourth cover 124 and is not exposed. FIG. 3 shows the state in which the fourth cover 124 is detached. In this state, the drive unit 9B is exposed.

[0038] The operation unit 120A is provided at the front end of the housing 11, in other words, at the downstream end of the housing 11 in the transport direction of the label 10A transported along the transport path R2. The operation unit 120B is provided at the upper end of the housing 11, in other words, at the end of the housing 11 on the side opposite to the side where the installation surface 110 is arranged. The operation units 120A and 120B are a plurality of push buttons for performing an input operation on the label winding device 1A.

[0039] <Printing unit 2B> As shown in FIGS. 1 and 2, the printing unit 2B can perform printing using a laminate type tape cassette TC. As shown in FIGS. 6 and 7, a thermal head 21, a platen holder 22, etc. are provided in the tape storage unit 2A as the printing unit 2B.

[0040] When the tape cassette TC is mounted on the tape storage unit 2A, the thermal head 21 is inserted into the head insertion portion of the tape cassette TC. The platen holder 22 is provided below the tape storage unit 2A and is supported so as to be rotatable about a rotation shaft 22C (see FIG. 6). As shown in FIG. 7, a platen roller 22A and a tape sub-roller 22B are rotatably supported on the platen holder 22. The platen roller 22A faces the thermal head 21. The tape sub-roller 22B is provided in front of the platen roller 22A and faces the drive roller Ts of the tape cassette TC. The platen holder 22 rotates in response to the drive of a motor Mp2 (see FIG. 38) and moves between a standby position and a printing position. The motor Mp2 is driven in conjunction with the opening and closing operation of a first cover 121 described later. When the motor Mp2 is driven in conjunction with the operation of opening the first cover 121, the platen holder 22 is placed in the standby position, and the platen roller 22A is separated from the thermal head 21. Also, when the motor Mp2 is driven in conjunction with the operation of closing the first cover 121, the platen holder 22 is placed in the printing position, the platen roller 22A approaches the thermal head 21, and the tape sub-roller 22B approaches the drive roller of the tape cassette TC.

[0041] As shown in FIG. 7, the tape cassette TC houses a first tape 101, a second tape 103, and an ink ribbon Ir. The first tape 101 is a transparent film tape made of PET. The second tape 103 is a tape in which a base material 102 and a release material 10B are laminated via an adhesive. The first tape 101 and the ink ribbon Ir are fed out from the tape cassette TC with the ink ribbon Ir disposed above the first tape 101.

[0042] When the platen holder 22 moves from the standby position to the printing position, the platen roller 22A overlaps the first tape 101 and the ink ribbon Ir and presses them against the thermal head 21. The platen roller 22A rotates and conveys the first tape 101 forward. At the same time, the thermal head 21 generates heat and the ink ribbon Ir is heated. As a result, the ink of the ink ribbon Ir is transferred onto the upper surface of the first tape 101 (hereinafter referred to as "printing surface Ut"). Thereby, character information including characters and the like is printed. After printing, the ink ribbon Ir separates from the first tape 101 and is wound back into the tape cassette TC.

[0043] Next, the second tape 103 is overlapped with the printed surface Ut of the printed first tape 101. The base material 102 of the second tape 103 contacts the printed surface Ut of the first tape 101. In this state, the first tape 101 and the second tape 103 pass between the drive roller Ts of the tape cassette TC and the tape sub-roller 22B. The printed label 10A is generated by the close adhesion of the base material 102 to the printed surface Ut of the first tape 101. The upper surface of the label 10A corresponds to the adhesive surface Ur to which the adhesive of the base material 102 adheres, and the release material 10B is affixed to the adhesive surface Ur. The label 10A and the release material 10B are referred to as "tape 10". The width direction of the tape 10 corresponds to the left-right direction. The conveyance path of the tape 10 from the printing unit 2B to the peeling guide mechanism 4 described later is referred to as "conveyance path R1". The conveyance direction of the tape 10 in the conveyance path R1 is referred to as "conveyance direction Y1". The conveyance direction Y1 faces forward.

[0044] <Cutting portion 2C> The cutting part 2C is arranged on the downstream side in the conveying direction Y1 with respect to the tape sub-roller 22B of the printing part 2B. As shown in FIGS. 46 and 47, the cutting part 2C has a full-cut cutting blade 23 and a half-cut cutting blade 24. The full-cut cutting blade 23 has a fixed blade 231 fixed above the conveying path R1 and a movable blade 232 movable below the conveying path R1. The fixed blade 231 extends in the left-right direction with the cutting edge facing downward. The movable blade 232 has a plate shape that bends and extends, and is rotatably supported by a rotation shaft 233. The rotation shaft 233 is provided to the left of the conveying path R1 and extends in the front-rear direction. The movable blade 232 has a left end portion 234 that bends and extends to the left of the rotation shaft 233 and a right end portion 235 that extends straight to the right of the rotation shaft 233. The left end portion 234 has a long hole 236. The right end portion 235 faces rightward with the cutting edge extending in the left-right direction facing upward. That is, the direction in which the right end portion 235 of the movable blade 232 faces coincides with the opening direction of the second opening 122A (see FIGS. 1 and 2) of the second cover 122. Therefore, if the tape 10 becomes clogged, the user can easily remove the clogged tape 10 from the second opening 122A to the cutting part 2C.

[0045] The cutting part 2C has a transmission part 237 that transmits the driving force of the motor Mp3 to the movable blade 232 to the left of the conveying path R1 and in front of the full-cut cutting blade 23. The transmission part 237 has a plurality of gear groups, and the driving shaft of the motor Mp3 meshes with the uppermost gear. The lowermost driving gear 238 of the transmission part 237 has a pin 239 that engages with the long hole 236 of the movable blade 232. The motor Mp3 rotates the driving gear 238 and moves the pin 239 in the long hole 236, thereby moving the movable blade 232 between the cutting position and the standby position. The cutting position is a position where, when viewed from the rear, the movable blade 232 rotates in the clockwise direction from the standby position and the cutting edge of the right end portion 235 intersects the fixed blade 231. The standby position is a position where, when viewed from the rear, the movable blade 232 rotates in the counterclockwise direction from the cutting position and the cutting edge of the right end portion 235 retracts below the conveying path R1. The full-cut cutting blade 23 can divide (fully cut) the tape 10 by moving the cutting edge of the movable blade 232 from below the conveying path R1 across the conveying path R1 upward with respect to the cutting edge of the fixed blade 231.

[0046] The half-cut cutting blade 24 is provided on the downstream side of the full-cut cutting blade 23 in the conveyance path R1. The half-cut cutting blade 24 has a fixed base 241 fixed above the conveyance path R1 and a movable blade 242 movable below the conveyance path R1. The fixed base 241 extends in the left-right direction and has a blade facing surface 241A facing downward, that is, facing the conveyance path R1. The movable blade 242 has a plate shape extending in the left-right direction and is rotatably supported by a rotation shaft 243. The rotation shaft 243 is provided to the left of the conveyance path R1 and extends in the front-rear direction. The movable blade 242 has a left end portion 244 extending straight to the left of the rotation shaft 243 and a right end portion 245 extending straight to the right of the rotation shaft 243. The left end portion 244 has a pin 246 protruding rearward at the end. The right end portion 245 faces rightward and has a cutting edge extending in the left-right direction facing upward. That is, the direction in which the right end portion 245 of the movable blade 242 faces coincides with the opening direction of the second opening 122A (see FIGS. 1 and 2) of the second cover 122. Therefore, if the tape 10 becomes clogged, the user can easily remove the clogged tape 10 from the second opening 122A to the cutting portion 2C. Also, the end portion of the right end portion 245 has a protrusion 247 protruding slightly above the cutting edge. The size of the protrusion 247 protruding above the cutting edge is equal to or less than the thickness of the release material 10B and is greater than at least half the thickness of the release material 10B.

[0047] The cutting part 2C has a transmission part 248 that transmits the driving force of the motor Mp4 to the movable blade 242, to the left of the conveyance path R1 and behind the half-cutting blade 24. The transmission part 248 has a plurality of gear groups, and the drive shaft of the motor Mp4 meshes with the uppermost gear. The lowermost drive gear 249 of the transmission part 248 has a long groove 250 with which the pin 246 of the movable blade 242 engages. The long groove 250 extends from near the rotation center of the drive gear 249 toward the outer periphery. The motor Mp4 rotates the drive gear 249 and moves the pin 246 in the long groove 250, thereby moving the movable blade 242 between the cutting position and the standby position. The cutting position is the position where, when viewed from the front, the movable blade 242 rotates counterclockwise from the standby position and the protrusion 247 of the right end 245 abuts against the blade contact surface 241A of the fixed base 241. In this case, a gap equal to or less than the thickness of the release material 10B is formed between the cutting edge of the movable blade 242 and the blade contact surface 241A. The standby position is the position where, when viewed from the front, the movable blade 242 rotates clockwise from the cutting position and the cutting edge of the right end 245 retracts below the conveyance path R1. The half-cutting blade 24 can cut the first tape 101 and the base material 102, that is, the label 10A, which are below the release material 10B during conveyance, by bringing the cutting edge of the movable blade 242 close to the blade contact surface 241A of the fixed base 241 and forming a gap equal to or less than the thickness of the release material 10B, and leave (half-cut) the release material 10B without cutting it.

[0048] <First roller 301> As shown in FIG. 8, the first roller 301 is provided on the downstream side in the conveyance direction Y1 of the tape 10 with respect to the cutting part 2C (see FIG. 7) and below the conveyance path R1. As shown in FIG. 9, the first roller 301 is composed of cylindrical bodies 301A, 301B, and 301C arranged at intervals in the left-right direction. The cylindrical bodies 301A, 301B, and 301C are arranged in order from the right side to the left side. The cylindrical bodies 301A, 301B, and 301C are rotatably supported about a rotation shaft 301K extending in the left-right direction. The first roller 301 conveys the tape 10 printed by the printing part 2B and passed through the cutting part 2C to the downstream side in the conveyance direction Y1 toward the peeling guide mechanism 4 described later.

[0049] As shown in FIG. 8, a fourth roller 304 is provided above the first roller 301. As shown in FIG. 10, the fourth roller 304 is composed of three cylindrical bodies arranged at intervals in the left - right direction. The three cylindrical bodies are arranged in order from the right side to the left side. The three cylindrical bodies are respectively opposed to the cylindrical bodies 301A, 301B, and 301C of the first roller 301 across the conveyance path R1 (see FIG. 8). The fourth roller 304 is rotatably supported by a support 31 provided above the first roller 301 about an axis extending in the left - right direction.

[0050] The fourth roller 304 is rotatably supported by the support 31. The support 31 has a bent plate shape and is biased upward by a spring (not shown). Also, as shown in FIG. 8, the support 31 biases the fourth roller 304 downward by a spring 31A held on the lower side.

[0051] As shown in FIG. 10, a D - cut shaft body 31B is arranged above the support 31. The shaft body 31B extends in the left - right direction and contacts the upper surface of the support 31 from above. A lever 31S connected to the left end portion of the shaft body 31B swings according to the opening and closing of the first cover 121 (see FIG. 1). The shaft body 31B rotates according to the swing of the lever 31S.

[0052] FIGS. 8 and 10 show the lever 31S and the shaft body 31B when the first cover 121 is in the closed state (see FIG. 1). As shown in FIG. 10, the curved surface portion 310B of the shaft body 31B is in contact with the support 31, and the distance between the center of the shaft body 31B and the support 31 is the largest. In this case, the support 31 moves downward against the biasing force of a spring (not shown). The fourth roller 304 supported by the support 31 approaches the first roller 301. Therefore, when the first cover 121 is in the closed state, as shown in FIG. 8, the fourth roller 304 sandwiches the tape 10 passing through the conveyance path R1 at the nip portion between the first roller 301. In this case, due to the rotation of the first roller 301, the tape 10 can be conveyed toward a peeling portion 4A described later, so that the label 10A can be peeled off by the peeling portion 4A. Hereinafter, the position of the fourth roller 304 in this state is referred to as the "clamping position".

[0053] Figures 11 and 13 show the lever 31S and the shaft body 31B when the first cover 121 is in the open state (see Fig. 3). As shown in Fig. 13, the flat portion 310A of the shaft body 31B is in contact with the support 31, and the distance between the center of the shaft body 31B and the support 31 is minimized. In this case, the support 31 moves upward under the biasing force of a spring (not shown). The fourth roller 304 supported by the support 31 moves upward relative to the first roller 301, and the nip portion is separated. Therefore, when the first cover 121 is in the open state, the fourth roller 304 is separated from the tape 10 passing through the conveyance path R1 as shown in Fig. 11, and the clamping of the tape 10 in the nip portion is released. In this case, even if the first roller 301 rotates, the tape 10 cannot be conveyed toward the peeling portion 4A, so that the label 10A cannot be peeled off by the peeling portion 4A. Hereinafter, the position of the fourth roller 304 in this state is referred to as the "separated position".

[0054] <Peeling guide mechanism 4> The peeling guide mechanism 4 includes a peeling portion 4A, a conveyance guide 4B, a pair of holding portions 4C, and a drive mechanism 4D. As shown in Fig. 9, the peeling portion 4A peels the label 10A from the peeling material 10B. The conveyance guide 4B guides the label 10A, the peeling material 10B, and the tape 10 in an appropriate conveyance direction. The pair of holding portions 4C hold the peeling portion 4A and the conveyance guide 4B. The drive mechanism 4D drives the peeling portion 4A, the conveyance guide 4B, and the pair of holding portions 4C.

[0055] As shown in Fig. 8, the peeling portion 4A is disposed on the downstream side of the first roller 301 in the conveyance direction Y1 of the tape 10. As shown in Fig. 9, the peeling portion 4A has an elongated plate shape and extends in the left-right direction. The corner of the front end portion of the peeling portion 4A (hereinafter referred to as the "tip portion 400") is curved.

[0056] As shown in FIG. 8, the conveyance guide 4B is arranged at a predetermined interval from the peeling part 4A. As shown in FIG. 9, the conveyance guide 4B has a base part 411 and a protruding part 412. The base part 411 has a plate shape and faces the tip part 400 of the peeling part 4A among the conveyance guides 4B. A curved part 41R that is curved in a concave shape is formed on the surface of the base part 411 that faces the tip part 400 of the peeling part 4A. The radius of curvature of the curved part 41R is referred to as r1. The protruding part 412 is composed of three protruding pieces 412A, 412B, and 412C that protrude from the front end part of the base part 411. The protruding pieces 412A, 412B, and 412C are arranged at intervals in the left - right direction from the right side to the left side in this order.

[0057] The pair of holding parts 4C each have an elongated plate shape and are separated in the left - right direction. The pair of holding parts 4C are connected to both left - right ends of the peeling part 4A and the conveyance guide 4B, and hold the peeling part 4A and the conveyance guide 4B from both sides in the left - right direction. Each of the pair of holding parts 4C has a hole through which the rotation shaft 301K of the first roller 301 is inserted. Each of the pair of holding parts 4C is rotatable about the rotation shaft 301K. In response to the rotation of the pair of holding parts 4C, the peeling part 4A and the conveyance guide 4B move in conjunction between the first position shown in FIGS. 11 - 13 and the second position shown in FIGS. 8 - 10. Further, each of the pair of holding parts 4C has a long hole 431 at a part on the side opposite to the side where the peeling part 4A is connected with respect to the hole through which the rotation shaft 301K is inserted.

[0058] As shown in FIG. 8, the tip 400 of the peeling portion 4A disposed at the second position and the conveyance guide 4B are located on the downstream side in the conveyance direction Y1 of the tape 10 with respect to the first roller 301. The conveyance path R1 of the tape 10 passes downstream between the first roller 301 and the fourth roller, extends obliquely downward forward along the first roller 301, and reaches the tip 400 of the peeling portion 4A. The label 10A of the tape 10 is peeled from the peeling material 10B as the peeling portion 4A bends the peeling material 10B, and is conveyed forward from the tip 400 of the peeling portion 4A. At this time, the adhesive surface Ur to which the peeling material 10B was attached among the label 10A faces upward, and the surface opposite to the adhesive surface Ur (hereinafter referred to as the "opposite surface Us") faces downward. On the other hand, the peeling material 10B from which the label 10A has been peeled is conveyed obliquely upward rearward from the tip 400 of the peeling portion 4A.

[0059] As shown in FIG. 14, the tip 400 of the peeling portion 4A disposed at the first position is located above the upper end of the first roller 301. The conveyance path R1 of the tape 10 passes downstream between the first roller 301 and the fourth roller and reaches the tip 400 of the peeling portion 4A. Since the bending angle of the peeling material 10B in the peeling portion 4A is gentler than in the case of the second position, the label 10A of the tape 10 is not peeled from the peeling material 10B. The tape 10 is conveyed obliquely upward rearward toward the paper discharge storage portion 16 (see FIG. 1) with the label 10A attached to the peeling material 10B. The conveyance path of the tape 10 that passes through the peeling portion 4A disposed at the first position is referred to as the conveyance path R4.

[0060] As shown in Fig. 9, the peeling part 4A and the conveying guide 4B arranged at the second position are held at a position in front of and above the holes through which the rotating shafts 301K of the pair of holding parts 4C are inserted. Therefore, with the peeling part 4A and the conveying guide 4B arranged at the second position, the own weight of the peeling part 4A acts on the pair of holding parts 4C with a counterclockwise force when viewed from the right. This direction coincides with the rotation direction (counterclockwise direction) of the pair of holding parts 4C when the peeling part 4A and the conveying guide 4B move from the first position (see Fig. 11) to the second position (see Fig. 8), and is opposite to the rotation direction (clockwise direction) of the pair of holding parts 4C when the peeling part 4A and the conveying guide 4B move from the second position (see Fig. 8) to the first position (see Fig. 11).

[0061] The drive mechanism 4D moves the peeling part 4A and the conveying guide 4B of the peeling guide mechanism 4 in conjunction between the first position and the second position. As shown in Figs. 9 and 12, the drive mechanism 4D has a pair of drive parts 46A and a rotating shaft 46C. The pair of drive parts 46A are each circular plate-shaped cams and are orthogonal to the left-right direction. The pair of drive parts 46A are spaced apart in the left-right direction. The right drive part 46A is adjacent to the left side of the right holding part 4C. The left drive part 46A is adjacent to the right side of the left holding part 4C. The rotating shaft 46C extends in the left-right direction and is installed between the pair of drive parts 46A. The pair of drive parts 46A are rotatable about the rotating shaft 46C.

[0062] As shown in Fig. 32, a motor Mw1 is provided below the left drive part 46A. The motor Mw1 is located below the conveying path R2 of the label 10A in the up-down direction. Also, a gear group G1 is interposed between the gear connected to the rotating shaft of the motor Mw1 and the left drive part 46A. The gear group G1 transmits the rotational driving force of the motor Mw1 to the left drive part 46A. Further, as shown in Figs. 9 and 12, the rotational driving force of the left drive part 46A rotated by the motor Mw1 is transmitted to the right drive part 46A via the rotating shaft 46C. Therefore, in response to the rotation of the motor Mw1, the pair of drive parts 46A rotate in conjunction.

[0063] Insertion portions 461 are provided on the left and right outer surfaces of each of the pair of drive portions 46A. The insertion portions 461 have a cylindrical shape and project outward to the left and right. The insertion portions 461 are inserted into the long holes 431 of the holding portions 4C disposed outside each of the pair of drive portions 46A.

[0064] For example, when moving the peeling portion 4A and the conveyance guide 4B from the second position shown in FIG. 9 to the first position shown in FIG. 12, the pair of drive portions 46A rotate in the clockwise direction as viewed from the right in the state shown in FIG. 9. In this case, the insertion portion 461 first moves downward along the long hole 431 from the state of being in contact with the upper end portion of the long hole 431 of the holding portion 4C, and then changes its direction and moves upward along the long hole 431. Then, as shown in FIG. 12, the insertion portion 461 moves until it comes into contact with the upper end portion of the long hole 431. In this process, the pair of holding portions 4C rotate in the clockwise direction as viewed from the right, and move the peeling portion 4A and the conveyance guide 4B from the second position to the first position. That is, regardless of whether the peeling portion 4A and the conveyance guide 4B are arranged at the first position or the second position, the insertion portion 461 is in a state of being in contact with the upper end portion of each of the long holes 431 of the pair of holding portions 4C.

[0065] As shown in FIGS. 9 and 12, when viewed from the left - right direction, a virtual arc Cm centered on the rotation axis 301K, which is the rotation center of the pair of holding portions 4C, is defined. The radius rm of the virtual arc Cm coincides with the distance between the rotation axis 301K and the rotation axis 46C of the drive mechanism 4D. In this case, the position of the insertion portion 461 when the peeling portion 4A and the conveyance guide 4B are arranged at the first position (see FIG. 12), the position of the insertion portion 461 when the peeling portion 4A and the conveyance guide 4B are arranged at the second position (see FIG. 9), and the position of the rotation axis 46C of the drive mechanism 4D are all arranged in the circumferential direction along the virtual arc Cm when viewed from the right.

[0066] Note that a load is applied to the peeling portion 4A when the label 10A is peeled from the peeling material 10B. Similarly, a load is applied to the conveyance guide 4B when guiding the label 10A, the peeling material 10B, the tape 10, etc. These loads are transmitted as a rotational force about the rotation axis 301K to the insertion portions 461 of each of the pair of drive portions 46A. Here, as described above, the position of the insertion portion 461 and the position of the rotation axis 46C when the peeling portion 4A and the conveyance guide 4B are respectively disposed at the first position and the second position are arranged along a virtual arc Cm centered on the rotation axis 301K. For this reason, even when a rotational force is transmitted to the insertion portion 461 in accordance with the loads applied to the peeling portion 4A and the conveyance guide 4B in a state where the peeling portion 4A and the conveyance guide 4B are respectively disposed at the first position or the second position, the peeling portion 4A and the conveyance guide 4B do not move due to this rotational force. Therefore, the position of the peeling portion 4A can be stabilized at the second position, so that the label 10A can be appropriately peeled. Also, since the position of the conveyance guide 4B can be stabilized at the first position or the second position, the label 10A, the peeling material 10B, and the tape 10 can be appropriately guided.

[0067] <Passage regions 300A, 300B> As shown in FIG. 8, a passage region 300A, which is a space through which the label 10A passes, is provided on the downstream side in the conveyance direction of the label 10A peeled from the peeling material 10B with respect to the peeling guide mechanism 4. The passage region 300A is a space sandwiched in the vertical direction by the lower wall 121A of the first cover 121 in a closed state and the opposing wall 121B that faces downward with respect to the lower wall 121A. In the passage region 300A, a part of a second roller 302 and driven rollers 311 to 313, which will be described later, is exposed.

[0068] The conveyance path R2 of the label 10A peeled off by the peeling portion 4A disposed at the second position is disposed within the passage region 300A. The conveyance direction of the label 10A conveyed along the conveyance path R2 is referred to as the "conveyance direction Y2". The conveyance guide 4B in the state of being disposed at the second position guides the label 10A along the conveyance path R2 in the conveyance direction Y2. Note that the conveyance guide 4B is spaced downward from the conveyance path R2. That is, the conveyance guide 4B in the state of being disposed at the second position is disposed at a position that does not obstruct the movement of the label 10A along the conveyance path R2, thereby guiding the label 10A in the conveyance direction Y2.

[0069] As shown in FIGS. 8 and 14, a passage region 300B, which is a space through which the release material 10B or the tape 10 passes, is provided on the downstream side in the conveyance direction of the release guide mechanism 4 with respect to the release guide mechanism 4. The passage region 300B is a space sandwiched in the front-rear direction by the rear wall 121C of the first cover 121 in the closed state and the opposing wall 121D opposing the rear wall 121C rearward. A part of the third roller 303 and the driven roller 323 described later is exposed in the passage region 300B.

[0070] As shown in FIG. 8, the conveyance path R3 of the release material 10B from which the label 10A has been peeled off by the peeling portion 4A disposed at the second position is disposed in the passage region 300B. The conveyance direction of the release material 10B conveyed along the conveyance path R3 is referred to as the conveyance direction Y3. As shown in FIG. 14, the conveyance path R4 of the tape 10 conveyed through the peeling portion 4A disposed at the first position is disposed within the passage region 300B. The conveyance direction of the tape 10 conveyed along the conveyance path R4 is referred to as the conveyance direction Y4. The conveyance guide 4B in the state of being disposed at the first position guides the tape 10 in the conveyance direction Y4.

[0071] <The second roller 302> As shown in FIG. 8, the second roller 302 is provided on the downstream side of the first roller 301 in the conveyance direction Y2 of the label 10A. As shown in FIG. 4, the second roller 302 is composed of cylindrical bodies 302A, 302B, and 302C that are spaced apart in the left-right direction. The cylindrical bodies 302A, 302B, and 302C are arranged in order from the right side to the left side. As shown in FIG. 8, the cylindrical bodies 302A, 302B, and 302C are rotatably supported about a rotation axis 302K extending in the left-right direction. The second roller 302 contacts the opposite surface Us of the label 10A from which the release material 10B has been peeled off by the peeling portion 4A disposed at the second position, and conveys it downstream along the conveyance path R2.

[0072] The driven roller 312 is provided above the second roller 302. As shown in FIGS. 4 and 15, the driven roller 312 is composed of bumps 312A, 312B, and 312C that are spaced apart in the left-right direction. The bumps 312A, 312B, and 312C are arranged in order from the right side to the left side. The bumps 312A to 312C are cylindrical and have irregularities at the peripheral end portions. The bumps 312A to 312C are rotatably supported by the first cover 121 about a rotation axis extending in the left-right direction.

[0073] The lower end portions of each of the bumps 312A, 312B, and 312C contact the upper ends of the cylindrical bodies 302A, 302B, and 302C of the second roller 302. The driven roller 312 contacts the adhesive surface Ur of the label 10A conveyed along the conveyance path R2, and sandwiches the label 10A between the driven roller 312 and the second roller 302.

[0074] As shown in FIG. 8, the driven roller 311 is provided upstream of the driven roller 312 in the conveyance direction Y2 of the label 10A and above the conveyance path R2 of the label 10A. As shown in FIGS. 4 and 15, the driven roller 311 is composed of bumps 311A, 311B, 311C, and 311D arranged at intervals in the left-right direction. The bumps 311A, 311B, 311C, and 311D are arranged in order from the right side to the left side. The bumps 311A to 311D are columnar and have irregularities on the peripheral end portions. The bumps 311A to 311D are rotatably supported by the first cover 121 about a rotation axis extending in the left-right direction. The bumps 311A to 311D contact the adhesive surface Ur of the label 10A conveyed along the conveyance path R2 and guide the label 10A in the conveyance direction Y2.

[0075] When the conveyance guide 4B moves between the first position and the second position, the protruding pieces 421A, 412B, and 412C (see FIG. 9 etc.) of the protruding portion 412 pass between the bumps 311A, 311B, 311C, and 311D of the driven roller 311. Specifically, the protruding piece 421A passes on the left side of the bump 311A, and the protruding piece 421C passes on the left side of the bump 311D. The protruding piece 421B passes between the bumps 311B and 311C. For this reason, when the conveyance guide 4B moves between the first position and the second position, the protruding portion 412 does not contact the driven roller 311.

[0076] As shown in FIG. 8, the driven roller 313 is provided downstream of the driven roller 312 in the conveyance direction Y2 of the label 10A and above the conveyance path R2 of the label 10A. As shown in FIGS. 4 and 15, the driven roller 313 is composed of bumps 313A, 313B, 313C, 313D, 313E, and 313F arranged at intervals in the left-right direction. The bumps 313A, 313B, 313C, 313D, 313E, and 313F are arranged in order from the right side to the left side. The bumps 313A to 313F are columnar and have irregularities on the peripheral end portions. The bumps 313A to 313F are rotatably supported by the first cover 121 about a rotation axis extending in the left-right direction. The bumps 313A to 313F contact the adhesive surface Ur of the label 10A conveyed along the conveyance path R2.

[0077] <Support section 32> As shown in FIG. 8, the support section 32 is provided below the driven roller 313 and is disposed in the passage area 300A. As shown in FIG. 4, the support section 32 is composed of ribs 32A, 32B, 32C, 32D, 32E, and 32F arranged at intervals in the left-right direction. The ribs 32A to 32F have a plate shape that is long in the front-rear direction and project upward from the opposing wall 121B. Inclined portions that incline upward toward the front are formed at the rear ends of the ribs 32A to 32F.

[0078] Each of the ribs 32A to 32F contacts the lower end of each of the bumps 311A to 311F of the driven roller 313. The support section 32 contacts the opposite surface Us of the label 10A conveyed along the conveyance path R2 and sandwiches the label 10A between it and the driven roller 313. Thereby, the support section 32 supports the opposite surface Us of the label 10A in a state where it has been completely peeled off from the peeling material 10B by the peeling section 4A from below. Note that the side on which the support section 32 supports the opposite surface Us of the label 10A coincides with the side on which the installation surface 110 of the housing 11 is disposed with respect to the label 10A. That is, the support section 32 supports the label 10A from the side of the installation surface 110. The label 10A supported by the support section 32 extends horizontally and is parallel to the installation surface 110.

[0079] <Third roller 303> As shown in FIG. 8, the third roller 303 is provided above the support body 31 that supports the fourth roller 304. As shown in FIG. 3, the third roller 303 has a columnar shape. As shown in FIG. 8, the third roller 303 is rotatably supported about a rotation axis 303K that extends in the left-right direction.

[0080] As shown in Fig. 8, the third roller 303 contacts the peeled material 10B from which the label 10A has been peeled by the peeling portion 4A disposed at the second position, and conveys the peeled material 10B along the conveyance path R3. The peeled material 10B is conveyed downstream in the conveyance direction Y3 toward the paper discharge storage portion 16 (see Fig. 1). Note that the conveyance path R3 of the peeled material 10B is located above the conveyance path R2 of the label 10A peeled from the peeled material 10B by the peeling portion 4A in the vertical direction. On the other hand, the installation surface 110 (see Fig. 1) of the housing 11 is located below the conveyance path R2 of the label 10A in the vertical direction. For this reason, the conveyance path R3 is located on the side opposite to the installation surface 110 in the vertical direction with respect to the conveyance path R2.

[0081] Also, as shown in Fig. 14, the third roller 303 contacts the tape 10 in a state where the label 10A is not peeled by the peeling portion 4A disposed at the first position, and conveys the tape 10 along the conveyance path R4. The tape 10 is conveyed downstream in the conveyance direction Y4 toward the paper discharge storage portion 16 (see Fig. 1).

[0082] As shown in Figs. 8 and 14, the driven roller 323 is provided obliquely upward in front of the third roller 303. As shown in Figs. 4 and 15, the driven roller 323 is composed of cylindrical bodies 323A, 323B, and 323C arranged at intervals in the left-right direction. The cylindrical bodies 323A, 323B, and 323C are arranged in order from the right side to the left side. The cylindrical bodies 323A, 323B, and 323C are rotatably supported by the first cover 121 about a rotation axis extending in the left-right direction. Therefore, when the first cover 121 is opened, the driven roller 323 supported by the first cover 121 is separated from the third roller 303 disposed on the housing 11 side, and the clamping of the peeled material 10B or the tape 10 in the nip portion is released. When the first cover 121 is closed, the driven roller 323 approaches the third roller 303, and it becomes possible to clamp and convey the peeled material 10B or the tape 10 in the nip portion.

[0083] Each of the cylindrical bodies 323A, 323B, and 323C contacts the third roller 303. As shown in FIG. 8, the cylindrical bodies 323A, 323B, and 323C contact the release material 10B conveyed along the conveyance path R3, and sandwich the release material 10B between them and the third roller 303. Also, as shown in FIG. 14, the cylindrical bodies 323A, 323B, and 323C contact the tape 10 conveyed along the conveyance path R4, and sandwich the tape 10 between them and the third roller 303.

[0084] Note that the length of the conveyance guide 4B in the left-right direction is substantially the same as the length between the right end of the cylindrical body 323A of the third roller 303 and the left end of the cylindrical body 323C. That is, in the left-right direction, a part of the conveyance guide 4B is disposed between the cylindrical bodies 323A and 323B and between the cylindrical bodies 323B and 323C.

[0085] As shown in FIGS. 8, 11, and 14, a guiding portion 127 is provided on the rear wall 121C of the first cover 121 on the upstream side in the conveyance directions Y3 and Y4 with respect to the driven roller 323. As shown in FIG. 15, the guiding portion 127 is composed of plate-like conductors 127A, 127B, 127C, 127D, 127E, and 127F, respectively. The conductors 127A, 127B, 127C, 127D, 127E, and 127F are arranged in order from the right side to the left side. The conductors 127A to 127B are orthogonal to the left-right direction and protrude from the rear wall 121C toward the passage region 300B.

[0086] The downstream ends of the conductors 127A and 127B in the conveyance directions Y3 and Y4 are disposed on both the left and right sides with respect to the cylindrical body 323A of the driven roller 323. The downstream ends of the conductors 127C and 127D in the conveyance directions Y3 and Y4 are disposed on both the left and right sides with respect to the cylindrical body 323B of the driven roller 323. The downstream ends of the conductors 127E and 127F in the conveyance directions Y3 and Y4 are disposed on both the left and right sides with respect to the cylindrical body 323C of the driven roller 323. The conductors 127A to 127F guide the tape 10 passing through the passage region 300B, which is guided by the conveyance guide 4B disposed at the first position, toward the paper discharge storage portion 16 along the conveyance path R4.

[0087] At the tips of Derivatives 127A to 127F, a curved portion 127R that is curved in a concave shape is formed. As shown in FIG. 11, the curved portion 41R of the conveyance guide 4B disposed at the first position is disposed upstream of the upstream end of the curved portion 127R in the conveyance direction Y4. The radius of curvature of the curved portion 127R is referred to as r2. The radius of curvature r1 of the curved portion 41R of the conveyance guide 4B is smaller than the radius of curvature r2 of the curved portion 127R (r1 < r2).

[0088] <Transfer unit 3B> The transfer unit 3B transmits the rotational driving force of the motor Mw2 to the first roller 301, the second roller 302, and the third roller 303 (see FIG. 8). As shown in FIG. 16, the motor Mw2 is disposed below the conveyance path R2 of the label 10A (see FIG. 8) in the vertical direction. The motor Mw2 is rotatable in both the counterclockwise direction (see FIG. 17) and the clockwise direction (see FIG. 18) when viewed from the right. Hereinafter, unless otherwise specified, the rotation direction (clockwise direction or counterclockwise direction) will be described assuming the state viewed from the right. The rotation of the motor Mw2 in the counterclockwise direction is referred to as "the motor Mw2 rotates forward". The rotation of the motor Mw2 in the clockwise direction is referred to as "the motor Mw2 rotates in reverse".

[0089] As described above, the motor Mw1 (see FIG. 3) that moves the peeling unit 4A and the conveyance guide 4B between the first position and the second position is also disposed below the conveyance path R2 of the label 10A in the vertical direction. For this reason, both the motors Mw1 and Mw2 are disposed on the same side (lower side) with respect to the virtual plane passing through the conveyance path R2 of the label 10A.

[0090] As shown in FIGS. 16 to 20, the transfer unit 3B includes a gear group including gears 360, 361, 362, 363, 364, 365A, 365B, 366A, 366B, 367, 368, and 369. The gear 360 is connected to the rotation shaft of the motor Mw2. The gears 361 to 364 are located on the right side with respect to the side plate 13A orthogonal to the left-right direction and are rotatably supported by the side plate 13A.

[0091] Gear 365A is connected to the rotating shaft 365C. Gear 365B is connected to the rotating shaft 365C via a clutch C2 described later. Gear 366A is connected to the rotating shaft 302K of the second roller 302 via a clutch C1 described later. Gear 366B is connected to the rotating shaft 302K of the second roller 302 via a clutch C3 described later. Gear 367 is connected to the rotating shaft 301K of the first roller 301 via a step conveyor mechanism 39 described later. Clutches C1 to C3 are one-way clutches.

[0092] Gears 360 and 361 mesh with each other. Gears 361 and 362 mesh with each other. Gears 362 and 363 mesh with each other. Gears 363 and 364 mesh with each other. Gears 364 and 365A mesh with each other. Gears 364 and 366A mesh with each other. Gears 365B and 366B mesh with each other. Gears 365B and 367 mesh with each other. Gears 365B and 368 mesh with each other.

[0093] As shown in FIG. 17, when the motor Mw2 rotates forward, the gear 364 rotates in the clockwise direction, and the gear 365A rotates in the counterclockwise direction. On the other hand, as shown in FIG. 18, when the motor Mw2 rotates in reverse, the gear 364 rotates in the counterclockwise direction, and the gear 365A rotates in the clockwise direction.

[0094] As shown in FIG. 17, when the gear 364 rotates in the clockwise direction, the clutch C1 connects the gear 366A that rotates in the counterclockwise direction according to the rotation of the gear 364 and the rotating shaft 302K. Thereby, the rotational driving force of the gear 364 is transmitted to the rotating shaft 302K, and the second roller 302 rotates in the counterclockwise direction. On the other hand, as shown in FIG. 18, when the gear 364 rotates in the counterclockwise direction, the clutch C1 disconnects the gear 366A that rotates in the clockwise direction according to the rotation of the gear 364 and the rotating shaft 302K. Thereby, the rotational driving force of the gear 364 is not transmitted to the rotating shaft 302K. Also, when the rotating shaft 302K rotates in the counterclockwise direction, the clutch C1 also disconnects the rotating shaft 302K and the gear 366A. Therefore, the rotation of the rotating shaft 302K in the counterclockwise direction is not suppressed by the gear 366A.

[0095] As shown in FIG. 17, when the gear 365A rotates in the counterclockwise direction, the clutch C2 disconnects the rotating shaft 365C that rotates in the clockwise direction in response to the rotation of the gear 365A and the gear 365B. Thereby, the rotational driving force of the gear 365A is not transmitted to the gear 365B. In this case, since the gear 367 meshing with the gear 365B does not rotate, the first roller 301 also does not rotate. On the other hand, as shown in FIG. 18, when the gear 365A rotates in the clockwise direction, the clutch C2 connects the rotating shaft 365C that rotates in the clockwise direction in response to the rotation of the gear 365A and the gear 365B. Thereby, the rotational driving force of the gear 365A is transmitted to the gear 365B, and the gear 365B rotates in the clockwise direction. In this case, the gear 367 meshing with the gear 365B rotates in the counterclockwise direction, and the first roller 301 also rotates in the counterclockwise direction.

[0096] As shown in FIG. 17, when the rotating shaft 302K rotates in the counterclockwise direction due to the rotational driving force of the gear 366A, the clutch C3 disconnects the rotating shaft 302K and the gear 366B. Therefore, the counterclockwise rotation of the rotating shaft 302K is not suppressed by the gear 366B. On the other hand, as shown in FIG. 18, when the gear 365B rotates in the clockwise direction, the clutch C3 connects the gear 366B that rotates in the counterclockwise direction in response to the rotation of the gear 365B and the rotating shaft 302K. Thereby, the rotational driving force of the gear 366B is transmitted to the rotating shaft 302K, and the second roller 302 rotates in the counterclockwise direction.

[0097] That is, in both the case where the motor Mw2 rotates forward and the case where it rotates backward, the second roller 302 rotates in the counterclockwise direction. This rotation direction coincides with the rotation direction in which the second roller 302 can convey the label 10A in the conveyance direction Y2 along the conveyance path R2. Further, the first roller 301 does not rotate when the motor Mw2 rotates forward, and the first roller 301 rotates in the counterclockwise direction when the motor Mw2 rotates backward. This rotation direction coincides with the rotation direction in which the first roller 301 can convey the tape 10 in the conveyance direction Y1 along the conveyance path R1.

[0098] Furthermore, when the second roller 302 rotates in the counterclockwise direction, the clutch C1 cuts off the gear 366A and the rotating shaft 302K, and the clutch C3 cuts off the gear 366B and the rotating shaft 302K. For this reason, for example, when the label 10A is forcibly moved in the conveyance direction Y2 in the step of attaching the label 10A, the rotation of the second roller 302 is not suppressed by the transmission unit 3B including the gears 366A and 366B.

[0099] As shown in FIGS. 19 to 21, the transmission unit 3B has a switching unit 3C that switches the meshing state between the gears 368 and 369 according to the positions of the peeling unit 4A and the conveyance guide 4B. The switching unit 3C has link mechanisms 37 and 38. The link mechanisms 37 and 38 are disposed to the left of the right holding unit 4C among the pair of holding units 4C that hold the peeling unit 4A and the conveyance guide 4B.

[0100] The link mechanism 37 has a columnar base 370, and arm portions 371 and 372 extending from the base 370. A through hole penetrating in the left - right direction is formed in the base 370. The rotating shaft 302K (see FIG. 16) of the second roller 302 is inserted into the through hole of the base 370. The link mechanism 37 is swingable about the rotating shaft 302K. The arm portion 371 extends downward from the base 370. A protruding portion 371A protruding to the right is provided at the tip of the arm portion 371. Further, an annular groove 47 is formed on the left surface of the right driving unit 46A among the pair of driving units 46A that drive the peeling unit 4A and the conveyance guide 4B. The protruding portion 371A of the arm portion 371 enters the groove 47. The arm portion 372 extends upward from the base 370. A long hole 372A long in the extending direction of the arm portion 372 is provided in the arm portion 372.

[0101] The link mechanism 38 has an elongated plate shape. At the upper end portion of the link mechanism 38, a gear 368 in a meshed state with the gear 365B is rotatably supported. At the lower end portion of the link mechanism 38, a protruding portion 381 protruding toward the left is provided. The protruding portion 381 enters the long hole 372A provided in the arm portion 372 of the link mechanism 37.

[0102] As shown in FIG. 19, with the peeling portion 4A and the conveying guide 4B arranged at the second position, the gear 368 meshes with the gears 365B and 369. Similarly, as shown in FIG. 21, with the peeling portion 4A and the conveying guide 4B arranged at the first position, the gear 368 meshes with the gears 365B and 369.

[0103] In this state, for example, when the motor Mw2 reverses as shown in FIG. 18, the rotational driving force of the gear 365B is transmitted to the gear 369 via the gear 368. Thereby, the rotating shaft 303K connected to the gear 369 rotates, and the third roller 303 connected to the rotating shaft 303K rotates in the clockwise direction. This rotation direction is consistent with the rotation direction in which the third roller 303 can convey the peeling material 10B in the conveying direction Y3 along the conveying path R3. Also, this rotation direction is consistent with the rotation direction in which the third roller 303 can convey the tape 10 in the conveying direction Y4 along the conveying path R4. Here, the transmission unit 3B adjusts the gear ratio of the gears 360 to 369 so that the conveying speed of the tape 10 or the peeling material 10B conveyed by the rotation of the third roller 303 is greater than the conveying speed of the tape 10 conveyed by the rotation of the first roller 301 when the motor Mw2 is reversely driven.

[0104] For example, as shown in FIG. 17, when the motor Mw2 rotates forward, the gear 365B does not rotate, so the rotational driving force is not transmitted to the gear 369 via the gear 368, and the third roller 303 does not rotate.

[0105] On the one hand, as shown in FIG. 20, in the process of the peeling portion 4A and the conveyance guide 4B moving between the first position and the second position, the pair of drive portions 46A rotate, and the protruding portion 371A of the arm portion 371 of the link mechanism 37 moves along the groove 47. Thereby, the link mechanism 37 swings about the rotation axis 302K. In response to the swinging of the link mechanism 37, a force acts on the protruding portion 381 inserted into the long hole 372A of the arm portion 372, and the link mechanism 38 moves. As a result, the gear 368 supported by the link mechanism 38 is separated from the gear 369. Thereby, the transmission path of the rotational driving force between the gears 368 and 369 is blocked. For this reason, for example, in this state, as shown in FIG. 22, even if the motor Mw2 is reversely driven and the gears 365B and 368 rotate, the gear 369 does not rotate, so the third roller 303 does not rotate either.

[0106] That is, the switching portion 3C enables the rotational driving force of the motor Mw2 to be transmitted to the third roller 303 and rotate the third roller 303 in a state where the peeling portion 4A and the conveyance guide 4B are arranged at the first position or the second position. On the other hand, the switching portion 3C makes the third roller 303 rotatable freely in a state where the peeling portion 4A and the conveyance guide 4B are arranged between the first position and the second position. For this reason, even when the tape 10 moves along the conveyance path R4 due to the peeling portion 4A and the conveyance guide 4B moving between the first position and the second position, the third roller 303 does not interfere with the movement of the tape 10, and the tape 10 can be moved.

[0107] As shown in FIGS. 17 and 18, the step conveyance mechanism 39 is provided inside the gear 367 having an annular shape. The step conveyance mechanism 39 has a pair of protruding pieces 39A protruding from the inside of the gear 367 toward the center, and a base portion 39B fixed to the rotation shaft 301K. The pair of protruding pieces 39A are provided at positions on opposite sides of each other across the rotation shaft 301K inside the gear 367. The base portion 39B has a pair of protruding pieces 39C protruding in opposite directions across the rotation shaft 301K. The pair of protruding pieces 39A and 39C are separated in the circumferential direction.

[0108] As shown in FIG. 18, when the gear 367 rotates counterclockwise in response to the rotation of the gear 365B, the rotary shaft 301K connected to the base 39B does not rotate until the pair of protruding pieces 39A of the gear 367 come into contact with the pair of protruding pieces 39C of the base 39B. After that, when the pair of protruding pieces 39A of the gear 367 come into contact with the pair of protruding pieces 39C of the base 39B, the rotational driving force of the gear 367 is transmitted to the rotary shaft 301K via the pair of protruding pieces 39A and 39C, and the rotary shaft 301K rotates. That is, as shown in FIG. 18, when the reverse driving of the motor Mw2 is started, the rotation of the first roller 301 is started after a lapse of a predetermined time from the start of the rotation of the second roller 302 and the third roller 303.

[0109] <Opening and closing member 5> As shown in FIG. 23, the opening and closing member 5 is disposed on the downstream side of the support portion 32 and above the conveyance path R2 of the label 10A. The opening and closing member 5 includes a base portion 51, a rotating body 52, and a rib 53.

[0110] The base portion 51 has a cylindrical portion 51A, an extending portion 51B, and a pair of side plate portions 51C. The cylindrical portion 51A is disposed around the rotary shaft 50 installed between the side plates 13A and 13B (see FIG. 16) spaced apart in the left-right direction, and is rotatable with respect to the rotary shaft 50. The extending portion 51B extends downward from the cylindrical portion 51A. The pair of side plate portions 51C are provided at both left and right ends of the extending portion 51B and are orthogonal to the left-right direction.

[0111] The opening and closing member 5 is swingably supported by the side plates 13A and 13B by the rotary shaft 50. The base portion 51 is swingable about the rotary shaft 50 in a direction in which the lower end portion of the extending portion 51B moves in the front-rear direction. The position of the opening and closing member 5 in a state where the lower end portion of the extending portion 51B has moved forward is referred to as a closed position. The opening and closing member 5 disposed at the closed position covers the adhesive surface Ur of the label 10A moving along the conveyance path R2 from above. The position of the opening and closing member 5 in a state where the lower end portion of the extending portion 51B has moved rearward is referred to as an open position. The opening and closing member 5 disposed at the open position does not cover the adhesive surface Ur of the label 10A. Note that the first cover 121 is similarly rotatably supported by the side plates 13A and 13B by the rotary shaft 50.

[0112] As shown in FIG. 24, the rotating body 52 has rotating bodies 52A, 52B, 52C, 52D, and 52E arranged in the left - right direction. The rotating bodies 52A, 52B, 52C, 52D, and 52E are arranged in this order from the right side to the left side. The rotating bodies 52A to 52E are disk - shaped and have irregularities at their peripheral ends. The rotating bodies 52A to 52E project outward from the extending portion 51B at the front side portion and the lower end portion rather than at approximately the center in the front - rear direction.

[0113] The rotating shaft 520 shown in FIG. 23 is inserted into the hole provided at the center of the rotating body 52. The rotating shaft 520 is rod - shaped and extends in the left - right direction. The rotating body 52 is rotatably supported by the base 51 by the rotating shaft 520. The rib 53 has a pair of ribs 53A, 53B, 53C, 53D, and 53E arranged in the left - right direction. The pair of ribs 53A to 53E are each plate - shaped and orthogonal to the left - right direction. The pair of ribs 53A are adjacent to both the left and right sides of the rotating body 52A. The pair of ribs 53B are adjacent to both the left and right sides of the rotating body 52B. The pair of ribs 53C are adjacent to both the left and right sides of the rotating body 52C. The pair of ribs 53D are adjacent to both the left and right sides of the rotating body 52D. The pair of ribs 53E are adjacent to both the left and right sides of the rotating body 52E. The shapes of the pair of ribs 53A to 53E are the same. The peripheral end of the rib 53 extends from the vicinity of the cylindrical portion 51A at the upper end of the extending portion 51B in a direction inclined forward with respect to the extending portion 51B. The rib 53 curves at the lower end and extends rearward.

[0114] As shown in FIG. 23, in a state where the opening - closing member 5 is disposed at the closing position, the rib 53 covers, from the left - right direction, the portion of the rotating body 52 that projects forward from the extending portion 51B. That is, the rib 53 projects outward from the radial end of the rotating body 52 at the portion of the rotating body 52 that projects forward from the extending portion 51B. The lower end of the rotating body 52 in FIG. 23 projects below the lower end of the rib 53.

[0115] An urging portion 56 is provided on the rear side of the base portion 51 of the opening and closing member 5. The urging portion 56 is a compression coil spring. The urging portion 56 applies a forward urging force to the opening and closing member 5. The opening and closing member 5 is urged by the urging portion 56 from the open position (see FIG. 25) toward the closed position (see FIG. 24).

[0116] The label 10A conveyed by the second roller 302 passes below the opening and closing member 5 along the conveyance path R2 and is supported by the support portion 32. At this time, the rotating body 52 of the opening and closing member 5 comes into contact with the adhesive surface Ur of the label 10A from above. Thereby, the opening and closing member 5 corrects the curvature of the label 10A that tends to curve upward.

[0117] <Guide member 8A> The guide member 8A is disposed on the downstream side of the label 10A in the conveyance direction Y2 with respect to the opening and closing member 5 and above the conveyance path R2. As shown in FIG. 25, the guide member 8A has an inclined surface 81A at the rear portion. The inclined surface 81A extends obliquely downward from the front end toward the rear end. The position of each front end portion of the inclined surface 81A, that is, the position of the upper end portion 811 disposed at the uppermost position among the inclined surfaces 81A, is located below the rotation shaft 50 that rotatably supports the opening and closing member 5 in the vertical direction. As shown in FIG. 23, the rear end portion of the inclined surface 81A, that is, the lower end portion 812 disposed at the lowermost position among the inclined surfaces 81A, is close to the conveyance path R2.

[0118] As shown in FIG. 24, the lower end portion of the opening and closing member 5 is close to the lower end portion 812 of the guide member 8A in a state where the opening and closing member 5 is disposed at the closed position. At this time, the rib 53 of the guide member 8A contacts the lower end portion 812 of the guide member 8A. On the other hand, as shown in FIG. 25, the lower end portion of the opening and closing member 5 is separated rearward from the lower end portion 812 of the guide member 8A in a state where the opening and closing member 5 is disposed at the open position.

[0119] As shown in FIG. 26, the cable 19 for winding the label 10A is mounted on the label winding device 1A from above the guide member 8A in a state of extending in the left - right direction. Note that a label 10A supported by the support portion 32 is disposed above the insertion portion 62A (see FIG. 18) of the pasting mechanism 6 described later.

[0120] As shown in FIGS. 26 and 27, the guide member 8A guides the cable 19 along the inclined surface 81A from a position near the upper end portion 811, that is, a position P11 separated from the label 10A, to a position near the lower end portion 812, that is, a position P13 close to the label 10A. The position P11 corresponds to a position downstream of the transport direction Y2 of the label 10A and separated from the support portion 32 on the opposite side. The position P13 corresponds to a position close to the adhesive surface Ur of the label 10A. The moving direction of the cable 19 guided by the guide member 8A (diagonally downward backward. Hereinafter, referred to as "guide direction Y11") is inclined upward with respect to the downward direction, which is a direction perpendicular to the label 10A, in the upstream side of the transport direction Y2 of the label 10A. The guide member 8A guides the cable 19 toward the adhesive surface Ur of the label 10A and the insertion portion 62A of the pasting mechanism 6.

[0121] Note that the guide direction Y11 of the cable 19 faces diagonally downward backward. On the extension line of the guide direction Y11, the installation surface 110 (see FIG. 1 etc.) of the housing 11 installed by a table or the like is arranged. Also, the guide direction Y11 has a component facing downward and a component facing the direction opposite to the transport direction Y2 of the label 10A (backward). That is, the guide member 8A guides the cable 19 in the guide direction Y11 by applying a force parallel to the transport direction Y2 of the label 10A and in the direction opposite to the transport direction Y2 to the cable 19.

[0122] In a state where the opening / closing member 5 is in the closed position, the cable 19 guided by the guide member 8A and moving in the guide direction Y11 contacts the rib 53 of the opening / closing member 5. An external force is applied to the lower end portion of the opening / closing member 5 from above by the cable 19. In this case, as shown in FIG. 27, the opening / closing member 5 moves from the closed position to the open position by moving the lower end portion backward against the biasing force of the biasing portion 56. Thereby, the opening 620B of the pasting mechanism 6 described later is switched from a state closed by the opening / closing member 5 (see FIG. 26) to an open state (see FIG. 27).

[0123] Note that the vertical position of the upper end portion 811 of the guide member 8A coincides with a part of the curved portions 127R (see FIGS. 8 and 15) of the conductors 127A to 127F that constitute the guide portion 127 provided on the rear wall 121C of the first cover 121. Also, the vertical position of the lower end portion 812 of the guide member 8A is located below the lower end portions of the curved portions 127R (see FIGS. 8 and 15) of the conductors 127A to 127F that constitute the guide portion 127 provided on the rear wall 121C of the first cover 121. For this reason, a part of each of the guide member 8A and the guide portion 127 coincides in vertical position. Also, when viewed in the direction parallel to the conveyance direction of the label 10A, that is, in the front-rear direction, a part of each of the guide member 8A and the guide portion 127 overlaps.

[0124] <Restriction portion 8B> As shown in FIGS. 26 and 27, a restriction portion 8B is formed below the lower end portion 812 of the guide member 8A. The restriction portion 8B has a recess 85 that is recessed forward. The recess 85 extends linearly in the left-right direction. The opening of the recess 85 faces rearward. The label 10A conveyed by the second roller 302 passes through the opening / closing member 5 and is further conveyed until the downstream end portion (hereinafter referred to as "end portion 105") contacts the restriction portion 8B. The restriction portion 8B can restrict the label 10A from being conveyed excessively downstream by bringing the end portion 105 of the label 10A into contact with the inner wall of the recess 85. The label 10A in a state where the conveyance is restricted is supported from the opposite surface Us side by the support portion 32.

[0125] As shown in FIG. 27, in the process of guiding the cable 19 downward toward the pasting mechanism 6 by the guide member 8A, the cable 19 contacts the label 10A from above. A part of the cable 19 is pasted on the adhesive surface Ur of the label 10A. As the cable 19 moves downward, the end portion 105 of the label 10A attempts to move in the vertical direction. In contrast, the restriction portion 8B restricts the end portion 105 of the label 10A from moving upward with respect to the conveyance path R2 by the inner wall of the recess 85. Hereinafter, the position of the label 10A in a state where the end portion 105 is disposed inside the recess 85 of the restriction portion 8B is referred to as the "pasting possible position". In the label 10A disposed at the pasting possible position, all the B portions are peeled off by the peeling portion 4A.

[0126] <Labeling mechanism 6> The labeling mechanism 6 attaches the label 10A supported by the support portion 32 in a state of being disposed at the attachable position to the cable 19 guided by the guide member 8A. As shown in FIGS. 26 and 27, the labeling mechanism 6 has a substantially cylindrical base portion 61 with a partially missing side surface. The center of the base portion 61 is rotatably supported by the side plates 13A and 13B of the frame 13 about a predetermined axis 6A. The axis 6A extends in the left - right direction.

[0127] As shown in FIGS. 26 to 28, the base portion 61 has a pair of bottom portions 62 provided at both left and right ends, and side portions 63A, 63B, and 63C. Each of the pair of bottom portions 62 has a disk shape and faces each other with a separation in the left - right direction.

[0128] As shown in FIGS. 26 and 27, each of the pair of bottom portions 62 is provided with an insertion portion 62A that is recessed from the peripheral end portion toward the axis 6A. The insertion portion 62A has a substantially U - shaped configuration and extends in the radial direction from a position (hereinafter referred to as the bottom portion 620A. Refer to FIG. 29) below the axis 6A by a predetermined distance in the bottom portion 62 to an opening 620B corresponding to a part of the peripheral end portion of the bottom portion 62.

[0129] The labeling mechanism 6 enables the cable 19 and the label 10A to be inserted into the insertion portion 62A with the opening 620B disposed at the upper end portion of the bottom portion 620A. Hereinafter, the rotational position of the labeling mechanism 6 at which the cable 19 can be inserted, that is, the rotational position of the labeling mechanism 6 in a state where the opening 620B is disposed at the upper end portion of the bottom portion 620A, is referred to as the initial position. In the following description, unless otherwise specified, it is assumed that the labeling mechanism 6 is disposed in the initial position.

[0130] The insertion part 62A is arranged on the downstream side of the second roller 302 and the support part 32 in the conveying direction Y2 of the label 10A, and below the conveying path R2. The opening 620B of the insertion part 62A opens toward the opposite surface Us (lower surface) of the label 10A supported by the support part 32 in a state of being arranged at the attachable position. As shown in FIG. 26, the opening 620B of the insertion part 62A is closed by the opening / closing member 5 arranged at the closed position. As shown in FIG. 27, the opening 620B of the insertion part 62A is not closed by the opening / closing member 5 arranged at the open position and is opened.

[0131] The attaching mechanism 6 has a first arm member 66, a second arm member 67, a first spring 68, and a second spring 69 inside the base 61. The first arm member 66 and the second arm member 67 hold the cable 19 with the cable 19 sandwiched therebetween when the label 10A is wound around the cable 19 by the attaching mechanism 6 (see FIG. 29). The first spring 68 and the second spring 69 bias the first arm member 66 and the second arm member 67 in order to hold the cable 19 by the first arm member 66 and the second arm member 67.

[0132] The first arm member 66 and the second arm member 67 each have a bent plate shape and extend in the left-right direction across between the pair of bottom surfaces 62. The first arm member 66 is provided on the downstream side with respect to the second arm member 67. The first arm member 66 and the second arm member 67 face each other in the front-rear direction.

[0133] As shown in FIG. 28, the upper end portion of the first arm member 66 is swingably supported about a rotating shaft 661 extending between a pair of bottom surface portions 62. The rotating shaft 661 is supported by the pair of bottom surface portions 62 in the vicinity of the downstream side in the conveying direction Y2 of the label 10A with respect to the opening 620B of the insertion portion 62A. Therefore, the upper end portion of the first arm member 66 is disposed in the vicinity of the downstream side in the conveying direction Y2 of the label 10A with respect to the opening 620B of the insertion portion 62A. The upper end portion of the second arm member 67 is swingably supported about a rotating shaft 671 extending between a pair of bottom surface portions 62. The rotating shaft 671 is supported by the pair of bottom surface portions 62 in the vicinity of the upstream side in the conveying direction Y2 of the label 10A with respect to the opening 620B of the insertion portion 62A. Therefore, the upper end portion of the second arm member 67 is disposed in the vicinity of the upstream side in the conveying direction Y2 of the label 10A with respect to the opening 620B of the insertion portion 62A.

[0134] A bent portion 66A recessed forward is formed near the lower end portion of the first arm member 66. A bent portion 67A recessed rearward is formed near the lower end portion of the second arm member 67. The bent portions 66A and 67A face each other in the front-rear direction with the axis 6A interposed therebetween.

[0135] The first spring 68 is interposed between the side surface portion 63B of the base portion 61 and the first arm member 66. The second spring 69 is interposed between the side surface portion 63C of the base portion 61 and the second arm member 67. The first spring 68 and the second spring 69 are compression springs having the same characteristics. The first spring 68 biases the first arm member 66 in a direction in which the first arm member 66 approaches the second arm member 67. The second spring 69 biases the second arm member 67 in a direction in which the second arm member 67 approaches the first arm member 66.

[0136] A rib 630 protruding upward is provided on the side surface portion 63A. The rear surface of the lower end portion of the first arm member 66 abuts against the front surface of the rib 630 by the biasing force of the first spring 68. Similarly, the front surface of the lower end portion of the second arm member 67 abuts against the rear surface of the rib 630 by the biasing force of the second spring 69.

[0137] As shown in FIG. 29, the label 10A disposed at the attachable position by being supported by the support portion 32 covers all of the openings 620B of the insertion portion 62A. The cable 19 guided downward by the guide member 8A contacts the label 10A and enters the insertion portion 62A together with the label 10A. At this time, the cable 19 follows the direction when being guided along the inclined surface 81A of the guide member 8A and moves obliquely rearward and backward. Thus, first, it contacts the second arm member 67 and moves the second arm member 67 backward against the biasing force of the second spring 69. The cable 19 is then guided downward (guide direction Y12) by contacting the second arm member 67.

[0138] Next, the cable 19 contacts the first arm member 66 and moves the first arm member 66 forward against the biasing force of the first spring 68. The cable 19 moves further downward. The cable 19 reaches the bottom 620A of the insertion portion 62A and is sandwiched and held in the front-rear direction between the bent portion 66A of the first arm member 66 and the bent portion 67A of the second arm member 67. Hereinafter, the position of the cable 19 that has reached the bottom 620A is referred to as the winding position Pm.

[0139] The label 10A is interposed between the cable 19 disposed at the winding position Pm, the first arm member 66, and the second arm member 67. The label 10A is wound and attached to a region approximately in the lower half of the cable 19, that is, approximately in the lower half of the outer peripheral surface of the cable 19. The label winding device 1A rotates the attaching mechanism 6 in this state. The attaching mechanism 6 rotates around the cable 19 about the axis 6A. In this case, the label 10A is guided to wind around the cable 19 disposed at the winding position Pm. Thereby, the label 10A is wound and attached to the cable 19.

[0140] <Holding member 7> As shown in FIGS. 1 and 4, the holding member 7 has holding members 7A and 7B. The holding member 7A is disposed on the right side with respect to the pasting mechanism 6 (see FIG. 6 etc.). As shown in FIG. 30, a cover 117A connected to the right surface of the side plate 13A covers the lower part of the holding member 7A from the right side. The holding member 7B is disposed on the right side with respect to the pasting mechanism 6 (see FIG. 6 etc.). As shown in FIG. 4, a cover 117B connected to the left surface of the side plate 13B covers the lower part of the holding member 7B from the left side. The holding members 7A and 7B have a symmetric structure with respect to a symmetric plane orthogonal to the left-right direction passing through the center in the left-right direction of the label winding device 1A.

[0141] The holding members 7A and 7B guide the cable 19 that has entered the insertion part 62A (see FIGS. 26 and 27) of the pasting mechanism 6 downward to the winding position Pm (see FIG. 29) at two positions separated in the left-right direction, and hold the cable 19 at the winding position Pm. Hereinafter, the details of the holding member 7A will be described, and the description of the holding member 7B will be omitted.

[0142] As shown in FIGS. 30 to 33, the holding member 7A includes a first clamping member 71, a second clamping member 72, and a biasing portion 73 (see FIG. 32). As shown in FIGS. 31 to 33, the first clamping member 71 extends obliquely downward rearward from behind the guide member 8A, bends forward halfway, and further extends obliquely downward forward. The second clamping member 72 extends obliquely downward forward from below the lower end portion 812 of the guide member 8A, bends rearward halfway, and extends obliquely downward rearward. The first clamping member 71 and the second clamping member 72 intersect near the lower end. The first clamping member 71 and the second clamping member 72 are swingably supported about a swing axis 70 extending in the left-right direction passing through the intersection point of the two. The swing axis 70 is provided on the side plate 13A of the frame 13 and extends to the right.

[0143] As shown in FIG. 33, the swing axis 70 is provided at a position spaced downward with respect to the winding position Pm which is the position of the cable 19 when the pasting mechanism 6 winds the label 10A. In other words, the position of the winding position Pm is spaced in the moving direction Y22 of the cable 19 inserted into the insertion part 62A of the pasting mechanism 6 with respect to the swing axis 70.

[0144] As shown in FIG. 32, a protruding portion 110A that protrudes rightward is provided below the swing shaft 70 in the side plate 13A. The lower end portion of the first clamping member 71 abuts against the protruding portion 110A from the rear. The lower end portion of the second clamping member 72 abuts against the protruding portion 110A from the front. The first clamping member 71 and the second clamping member 72 are held at positions where their respective lower end portions are in contact with the protruding portion 110A by the biasing force of a biasing portion 73 described later.

[0145] As shown in FIG. 30, the cover 117A covers the lower portions of the first clamping member 71 and the second clamping member 72 respectively. The cover 117A has a recessed portion 119A that is recessed downward. The winding position Pm is arranged at the bottom of the recessed portion 119A.

[0146] Hereinafter, as shown in FIGS. 31 to 33, a portion above the swing shaft 70 in the front end portion of the first clamping member 71 is referred to as a first opposing portion 710. A portion above the swing shaft 70 in the rear end portion of the second clamping member 72 is referred to as a second opposing portion 720. The second opposing portion 720 of the second clamping member 72 is arranged in front of the first opposing portion 710 of the first clamping member 71. The holding member 7 guides the cable 19 downward to the winding position Pm through a gap between the first opposing portion 710 of the first clamping member 71 and the second opposing portion 720 of the second clamping member 72, and holds the cable 19 in the front-rear direction at the winding position Pm.

[0147] The first clamping member 71 has a first inclined portion 711 at the upper end portion of the first opposing portion 710. The first inclined portion 711 extends obliquely upward and rearward toward the tip in a direction inclined with respect to the vertical direction. More specifically, the first inclined portion 711 is arranged behind the inclined surface 81A of the guide member 8A. The distance in the front-rear direction between the first inclined portion 711 and the inclined surface 81A becomes larger as it goes upward. That is, the first inclined portion 711 is inclined so that the distance from the inclined surface 81A becomes larger as it goes upward. The first inclined portion 711 guides the cable 19 toward the insertion portion 62A. The first inclined portion 711 is inclined with respect to the moving direction Y22 (see FIG. 33) when the cable 19 is inserted into the insertion portion 62A.

[0148] As shown in FIG. 32, the biasing portion 73 is a torsion spring wound around the swing shaft 70. One end portion 73A of the biasing portion 73 is connected inside the first clamping member 71. The other end portion 73B of the biasing portion 73 is connected inside the second clamping member 72. The biasing portion 73 biases the first clamping member 71 in the counterclockwise direction and biases the second clamping member 72 in the clockwise direction. Thereby, the biasing portion 73 biases the first clamping member 71 and the second clamping member 72 in a direction in which the first opposing portion 710 and the second opposing portion 720 approach each other. The first clamping member 71 and the second clamping member 72 are held at positions where their respective lower end portions abut against the protruding portion 110A by the biasing force of the biasing portion 73.

[0149] As shown in FIGS. 34 and 35, the holding member 7 is provided with a pressing member 76 and a protruding portion 71D. The pressing member 76 has a first pressing member 77 and a second pressing member 78.

[0150] The first pressing member 77 is installed between the first clamping members 71 of the holding members 7A and 7B respectively. The first pressing member 77 has an elongated bar shape in the left-right direction and is orthogonal to the front-back direction. The first pressing member 77 is connected to the vicinity of the upper end portion of the first opposing portion 710 on the inner surface 71U which is the surface of the first clamping member 71 closer to the opening / closing member 5. The length between the first clamping members 71 of the holding members 7A and 7B respectively is the length in the direction orthogonal to the conveyance direction Y2 of the label 10A, that is, longer than the width of the label 10A. For this reason, the length of the first pressing member 77 in the left-right direction is also longer than the width of the label 10A.

[0151] The second pressing member 78 is installed between the second clamping members 72 of the holding members 7A and 7B, respectively. The second pressing member 78 is a columnar rotating member and is rotatable about a rotation axis extending in the left-right direction. The second pressing member 78 is formed of elastic rubber. The rotation axis of the second pressing member 78 is connected to the vicinity of the upper end portion of the inner surface of the second clamping member 72. As shown in FIGS. 31 to 45, in a state where the holding member 7 is viewed from the left-right direction, a part of the second pressing member 78 protrudes upward and rearward with respect to the upper end portion of the second clamping member 72. Hereinafter, this protruding portion will be referred to as "protruding portion 78A". Note that the length between the second clamping members 72 of the holding members 7A and 7B, respectively, is the length in the direction orthogonal to the conveyance direction Y2 of the label 10A, that is, longer than the width of the label 10A. For this reason, the length of the second pressing member 78 in the left-right direction is also longer than the width of the label 10A.

[0152] As shown in FIG. 34, in a state where the first clamping members 71 and the second clamping members 72 of the holding members 7A and 7B, respectively, do not sandwich the cable 19 (see FIGS. 31 and 32), the first pressing member 77 is located on the rear side with respect to the second pressing member 78. The front end portion of the first pressing member 77 contacts the rear end portion of the second pressing member 78. Further, as shown in FIG. 26, the first pressing member 77 and the second pressing member 78 are located below the label 10A supported by the support portion 32 in a state where they are arranged at attachable positions and are close to the opposite surface Us of the label 10A. On the other hand, as shown in FIG. 37, in a state where the first clamping members 71 and the second clamping members 72 of the holding members 7A and 7B, respectively, sandwich the cable 19 therebetween (see FIG. 33), the first pressing member 77 and the second pressing member 78 are separated from each other in the front-rear direction.

[0153] Protruding portions 71D protruding inward are further provided on the inner surfaces 71U of the first clamping members 71 of the holding members 7A and 7B, respectively. As shown in FIGS. 36 and 37, the protruding portion 71D is located in front of the protruding portion 51D protruding outward from the side plate portion 51C of the opening / closing member 5. The protruding portions 51D and 71D are arranged on the outer side in the left-right direction with respect to the insertion portion 62A of the attaching mechanism 6.

[0154] As shown in FIG. 31, when the cable 19 is attached to the label winding device 1A, the cable 19 is guided obliquely downward and backward along the inclined surface 81A of the guide member 8A and moves in the moving direction Y21. The cable 19 comes into contact with the lower end of the opening / closing member 5, and the opening / closing member 5 moves from the closed position toward the open position. The cable 19 further moves obliquely downward and backward. At this time, as shown in FIG. 27, the cable 19 comes into contact with the adhesive surface Ur of the label 10A supported by the support portion 32 in a state where it is disposed at an attachable position and moves downward. At this time, the label 10A is sandwiched between the cable 19 and the first pressing member 77 and the second pressing member 78 located below the label 10A. The first pressing member 77 and the second pressing member 78 come into contact with the opposite surface Us of the label 10A and support the label 10A from the side of the opposite surface Us. Thereby, the label 10A is pressed against the upper cable 19.

[0155] Furthermore, the cable 19 moves downward and comes into contact with the first inclined portion 711 of the first clamping member 71. As shown in FIG. 33, the first clamping member 71 swings in the clockwise direction against the biasing force of the biasing portion 73. The first clamping member 71 and the second clamping member 72 are separated from each other. At this time, as shown in FIG. 29, the first pressing member 77 and the second pressing member 78 are separated in the front-rear direction. The first pressing member 77 comes into contact with the opposite surface Us of the cable 19 located at the rear and presses the label 10A forward toward the cable 19. Also, the protruding portion 78A of the second pressing member 78 guides the cable 19 backward while rotating. Then, the second pressing member 78 comes into contact with the opposite surface of the cable 19 located at the rear and presses the label 10A backward toward the cable 19. Thereby, the first pressing member 77 and the second pressing member 78 come into contact with the opposite surface Us of the label 10A from both the front and rear sides and press the label 10A against the cable 19.

[0156] Further, as shown in FIG. 36, the protruding portion 71D of the first clamping member 71 contacts the protruding portion 51D of the opening / closing member 5 from the front and pushes the opening / closing member 5 rearward. The opening / closing member 5 moves from the closed position toward the open position, and as shown in FIG. 37, the opening 620B of the insertion portion 62A of the sticking mechanism 6 opens. As shown in FIG. 33, the cable 19 passes through the opened opening 620B and enters the insertion portion 62A. The first clamping member 71 and the second clamping member 72 clamp the cable 19 from the front and rear directions. The cable 19 moves in the moving direction Y22 toward the lower winding position Pm and is then held at the winding position Pm.

[0157] On the other hand, when the cable 19 is detached from the label winding device 1A, an upward force is applied to the cable 19 at the winding position Pm. The cable 19 passes through the opened opening 620B and is taken out from the insertion portion 62A. After the cable 19 is taken out from the insertion portion 62A, the first clamping member 71 swings in the clockwise direction against the biasing force of the biasing portion 73, and the second clamping member 72 swings in the counterclockwise direction against the biasing force of the biasing portion 73 (see FIGS. 31 and 32). At this time, the protruding portion 71D of the first clamping member 71 moves forward with respect to the protruding portion 51D of the opening / closing member 5. The opening / closing member 5 returns from the open position (see FIG. 37) to the original closed position (see FIG. 36). The opening 620B of the insertion portion 62A is closed by the opening / closing member 5 disposed at the closed position.

[0158] <Electrical Configuration> Referring to FIG. 38, the electrical configuration of the label winding device 1A will be described. The label winding device 1A includes a CPU 91A, a ROM 91B, a RAM 91C, a flash memory 91D, and an input / output interface 91E, and these are connected via a data bus 92.

Sensor Sp1 is a contact sensor for detecting the open / closed state of the second cover 122. Sensor Sp2 is a contact sensor for detecting whether the tape cassette TC is mounted in the tape storage portion 2A.

[0162] <Tape mounting process> Referring to Fig. 39, the tape mounting process will be described. The tape mounting process is started when an operation for performing the work of newly mounting the tape cassette TC in a state where the tape cassette TC is not mounted is input via the operation unit 120A, and the CPU 91A reads and executes the program stored in the flash memory 91D. It should be noted that it is assumed that the second cover 122 is in a closed state at the start of the tape mounting process. Also, since the first cover 121 is in a closed state, the fourth roller 304 is arranged at a clamping position close to the first roller 301.

[0163] The CPU 91A controls the drive circuit MC to rotate the motor Mw1, and arranges the peeling unit 4A and the conveyance guide 4B at the first position (S101, see FIG. 14). For this reason, in the label winding device 1A, before the tape cassette TC used for printing is mounted on the tape storage unit 2A, the peeling unit 4A and the conveyance guide 4B are arranged at the first position, and in this state, the printing process (see FIG. 40) described later is started.

[0164] Next, when an input operation indicating that the mounting of the tape cassette TC is completed is input via the operation unit 120A, the CPU 91A determines whether a signal indicating that the second cover 122 is closed is output from the sensor Sp1, and a signal indicating that a new tape cassette TC is mounted on the tape storage unit 2A is output from the sensor Sp2 (S107). If the CPU 91A determines that the second cover 122 is not closed or a new tape cassette TC is not mounted (S107: NO), the process returns to S107. If the CPU 91A determines that the second cover 122 is closed and a new tape cassette TC is mounted on the tape storage unit 2A (S107: YES), it controls the drive circuit MC to rotate the motor Mp2, and moves the platen holder 22 from the standby position to the printing position. As a result, the platen roller 22A approaches the thermal head 21, and the tape sub-roller 22B approaches the drive roller Ts of the tape cassette TC. The platen roller 22A overlaps the first tape 101 fed out from the tape cassette TC with the ink ribbon Ir, and presses it against the thermal head 21 (see FIG. 7).

[0165] The CPU 91A controls the drive circuit MC to reversely drive the motor Mw2. In this case, as shown in FIG. 18, the first roller 301 and the second roller 302 rotate counterclockwise, and the third roller 303 rotates clockwise (S109). The first roller 301 sandwiches the tape 10 fed out from the tape cassette TC between itself and the fourth roller 304, and conveys it in the conveyance direction Y1 along the conveyance path R1 (see FIG. 14).

[0166] Based on the signal output from the sensor Sw2, the CPU 91A determines whether the leading end of the tape 10 has reached the position Ps2 (see FIG. 14) on the downstream side of the third roller 303 in the conveyance direction Y4 (S111). If the CPU 91A determines that the leading end of the tape 10 has not reached the position Ps2 (S111: NO), the process returns to S111. If the CPU 91A determines that the leading end of the tape 10 has reached the position Ps2 (S111: YES), it controls the drive circuit MC to stop the reverse drive of the motor Mw2 started in the process of S109 (S113). As a result, the rotations of the first roller 301, the second roller 302, and the third roller 303 stop. Since the leading end of the tape 10 has reached the position Ps2, the third roller 303 is in a state of sandwiching the tape 10 between it and the driven roller 323. That is, the tape 10 can be conveyed by the rotation of the third roller 303. The CPU 91A ends the tape mounting process.

[0167] <Main Process> Referring to FIGS. 40 to 43, FIG. 48, and FIG. 49, the main process will be described. The user operates the operation unit 120A to select print data indicating the desired print content from among a plurality of preset print data. The user inputs the number of copies of the label 10A to be created and performs an operation to start the operation of winding the label 10A around the cable 19. The main process is started when the CPU 91A reads and executes a program stored in the flash memory 91D. Since the first cover 121 is in a closed state, the fourth roller 304 is arranged at a clamping position close to the first roller 301.

[0168] As shown in FIG. 40, first, the CPU 91A controls the drive circuit MC to rotate the motor Mw1 and arranges the peeling unit 4A and the conveyance guide 4B at the first position (S131, see FIG. 14). When the main process is executed immediately after the tape mounting process shown in FIG. 39, the peeling unit 4A and the conveyance guide 4B are already arranged at the first position by the process of S101 (see FIG. 48(A)).

[0169] The CPU 91A controls the drive circuit MC to reversely drive the motor Mw2. In this case, as shown in Fig. 18, the first roller 301 and the second roller 302 rotate counterclockwise, and the third roller 303 rotates clockwise (S133). The first roller 301 sandwiches the tape 10 fed out from the tape cassette TC between itself and the fourth roller 304, and conveys it in the conveyance direction Y1 along the conveyance path R1 (see Fig. 14). Also, the third roller 303 sandwiches the tape 10 between itself and the driven roller 323, and conveys the tape 10 in the conveyance direction Y4 along the conveyance path R4 (see Fig. 14).

[0170] The CPU 91A controls the drive circuit MC to rotate the motor Mp1. Thereby, the platen roller 22A rotates, and conveys the first tape 101 of the tape 10 and the ink ribbon Ir held between itself and the thermal head 21 in the conveyance direction Y1 (see Fig. 7). The CPU 91A controls the drive circuit HC to heat the thermal head 21. The ink of the ink ribbon heated by the heat of the thermal head 21 is transferred onto the first tape 101 of the tape 10. Thereby, printing on the first tape 101 is started (S135). Also, the printed first tape 101 and the second tape 103 pass between the drive roller Ts of the tape cassette TC and the tape sub-roller 22B. The base material 102 of the second tape 103 adheres to the printed surface Ut of the first tape 101, and the generation of the printed label 10A is started. Printing on the first tape 101 is continuously performed as the tape 10 is conveyed. After starting printing by the process of S135, the CPU 91A controls the printing position on the tape 10 according to the rotation speed of the motor Mw1 that drives the platen roller 22A.

[0171] When the reverse driving of the motor Mw2 is started by the process of S133, after a lapse of a predetermined time since the rotation of the second roller 302 and the third roller 303 is started by the step conveyance mechanism 39 (see FIGS. 17 and 18), the rotation of the first roller 301 is started. Further, the CPU 91A adjusts the rotation speed of the motor Mp1 that drives the platen roller 22A so that the conveyance speed of the tape 10 by the third roller 303 whose rotation is started by the process of S133 is greater than the conveyance speed of the tape 10 by the platen roller 22A. Thereby, the slack of the tape 10 on the downstream side in the conveyance direction Y4 from the third roller 303 is suppressed.

[0172] Based on the number of rotations of the motor Mw1 since the start of printing, when the end portion 105 on the downstream side in the conveyance direction Y1, that is, the portion that becomes the leading end of the label 10A, has moved to the position of the cutting portion 2C when the label 10A is generated, the CPU 91A controls the drive circuit MC and stops the reverse driving of the motor Mw2 started in the process of S133 (S137). Thereby, the rotations of the first roller 301, the second roller 302, and the third roller 303 are stopped. The CPU 91A controls the drive circuit MC to rotate the motor Mp4. Thereby, the half-cut cutting blade 24 performs a half-cut on the portion that becomes the end portion 105 on the downstream side in the conveyance direction Y1 in the generated label 10A (see S139, FIG. 48(B)). In FIGS. 48 and 49, the printed portion on the first tape 101 is shown in black.

[0173] The CPU 91A controls the drive circuit MC to reversely drive the motor Mw2. The first roller 301 and the second roller 302 rotate counterclockwise, and the third roller 303 rotates clockwise (S141). The first roller 301 sandwiches the tape 10 between it and the fourth roller 304 and conveys it in the conveyance direction Y1 along the conveyance path R1. The third roller 303 sandwiches the tape 10 between it and the driven roller 324 and conveys it in the conveyance direction Y4 along the conveyance path R4. The CPU 91A continuously controls the printing position on the tape 10 according to the number of rotations of the motor Mw1 (S142).

[0174] Based on the rotational speed of the motor Mw1 since the start of printing, after the downstream end 105 of the label 10A where generation started has moved to the path switching position that is downstream of the cutting part 2C in the conveyance direction Y1 and upstream of the peeling part 4A in the conveyance direction Y1, the CPU91A controls the drive circuit MC and stops the reverse drive of the motor Mw2 that started in the process of S141 (S143). As a result, the rotations of the first roller 301, the second roller 302, and the third roller 303 stop. The CPU91A controls the drive circuit MC to rotate the motor Mw1 and moves the peeling part 4A and the conveyance guide 4B from the first position to the second position (see S144, FIG. 8, FIG. 48(C)).

[0175] The CPU91A controls the drive circuit MC to reversely drive the motor Mw2. The first roller 301 and the second roller 302 rotate counterclockwise, and the third roller 303 rotates clockwise (S145). The first roller 301 sandwiches the tape 10 between it and the fourth roller 304 and conveys it in the conveyance direction Y1 along the conveyance path R1. The third roller 303 sandwiches the tape 10 between it and the driven roller 323 and conveys it in the conveyance direction Y4 along the conveyance path R4. The CPU91A continuously controls the printing position on the tape 10 according to the rotational speed of the motor Mw1 (S146). The CPU91A advances the process to S147 (see FIG. 41).

[0176] As shown in FIG. 41, based on the rotational speed of the motor Mw1 since the start of printing, when the upstream end in the conveyance direction Y1 (hereinafter referred to as "end 106"), that is, the part that becomes the rear end of the label 10A, has moved to the position of the cutting part 2C when the label 10A was generated, the CPU91A controls the drive circuit MC and stops the reverse drive of the motor Mw2 that started in the process of S133 (S147). As a result, the rotations of the first roller 301, the second roller 302, and the third roller 303 stop. The CPU91A controls the drive circuit MC to rotate the motor Mp4. As a result, the half - cut cutting blade 24 half - cuts the part that becomes the upstream end 106 in the conveyance direction Y1 of the generated label 10A (see S148, FIG. 49(A)).

[0177] The CPU 91A controls the drive circuit MC to reversely drive the motor Mw2. In this case, as shown in FIG. 18, the first roller 301 and the second roller 302 rotate in the counterclockwise direction, and the third roller 303 rotates in the clockwise direction (S151). The first roller 301 sandwiches the tape 10 fed out from the tape cassette TC between itself and the fourth roller 304, and conveys it in the conveyance direction Y1 along the conveyance path R1 (see FIG. 8). Also, the third roller 303 sandwiches the tape 10 between itself and the driven roller 323, and conveys it in the conveyance direction Y4 toward the paper discharge accommodating portion 16 along the conveyance path R4. The label 10A is peeled off from the peeling material 10B as it passes through the peeling portion 4A arranged at the second position. The label 10A peeled off from the peeling material 10B is conveyed in the conveyance direction Y2 toward the second roller 302 along the conveyance path R2 (see FIG. 8). Further, the third roller 303 sandwiches the peeling material 10B from which the label 10A has been peeled between itself and the driven roller 323, and conveys it in the conveyance direction Y3 toward the paper discharge accommodating portion 16 along the conveyance path R4 (see FIG. 8). The peeling material 10B is guided into the accommodating port 16A by the inclined portion 121F at the tip portion 121E of the first cover 121, and is rounded by the roller 16B, and is accommodated in the paper discharge accommodating portion 16. The peeling material 10B is rounded and accommodated in the paper discharge accommodating portion 16, and further enters the mounting area 11B having the tape accommodating portion 2A, and is held in the housing 11. The CPU 91A continuously controls the printing position on the tape 10 according to the rotation speed of the motor Mw1 (S152). Since the printing on the first label 10A is completed, the CPU 91A controls the printing on the second label 10A.

[0178] The CPU 91A determines whether the end portion 106 of the label 10A half-cut in the process of S148 has passed through the peeling portion 4A (S153). When the rotation speed of the motor Mw2 after the start of the reverse drive of the motor Mw2 by the process of S151 is less than the first specified number, the CPU 91A determines that the end portion 106 of the label 10A has not passed through the peeling portion 4A (S153: NO). In this case, the CPU 91A returns the process to S153.

[0179] On the other hand, when the number of revolutions of the motor Mw2 after starting the reverse drive of the motor Mw2 by the process of S151 becomes equal to or greater than the first specified number, the CPU 91A determines that the end portion 106 of the label 10A has passed through the peeling portion 4A (S153: YES, see Fig. 49(B)). In this case, all of the generated label 10A has been peeled off by the peeling portion 4A. The CPU 91A controls the drive circuit MC and stops the reverse drive of the motor Mw2 started in the process of S151 (S155). As a result, the rotations of the first roller 301, the second roller 302, and the third roller 303 stop.

[0180] The CPU 91A controls the drive circuit MC to drive the motor Mw2 in the forward rotation. In this case, as shown in Fig. 17, the first roller 301 and the third roller 303 do not rotate, and only the second roller 302 rotates in the counterclockwise direction (S157). As a result, only the label 10A peeled from the peeling material 10B by the peeling portion 4A is conveyed in the conveyance direction Y2 by the second roller 302. On the other hand, since the second roller 302 does not rotate, the tape 10 is not fed out from the tape cassette TC. Also, since the third roller 303 does not rotate, the peeling material 10B from which the label 10A has been peeled is not conveyed.

[0181] The CPU 91A determines whether the label 10A has been conveyed by the second roller 302 whose rotation has been started by the process of S157 and has reached the attachable position (S161). When the number of revolutions of the motor Mw2 after starting the forward rotation drive of the motor Mw2 by the process of S157 is less than the second specified number, the CPU 91A determines that the label 10A has not reached the attachable position (S159: NO). In this case, the CPU 91A returns the process to S159.

[0182] On the other hand, when the rotation speed of the motor Mw2 after starting the forward rotation drive of the motor Mw2 by the process of S157 becomes equal to or greater than the second specified number, the CPU 91A determines that the label 10A has reached the attachable position (S159: YES, see FIG. 49(C)). The CPU 91A controls the drive circuit MC and stops the forward rotation drive of the motor Mw2 started in the process of S157 (S161). Thereby, the rotation of the second roller 302 stops. The CPU 91A executes a winding process (see FIG. 42) to attach and wind the label 10A around the cable 19 (S163). After the completion of the winding process, the CPU 91A updates a counter (not shown) that counts the number of created labels 10A, and if the number of created labels 10A has not reached the number of created labels input by the user (S165: NO), the process returns to S145. When the number of created labels 10A reaches the number of created labels input by the user (S165: YES), the CPU 91A controls the drive circuit MC to rotate the motor Mw1 and arranges the peeling part 4A and the conveyance guide 4B at the first position (S166, see FIG. 14). The CPU 91A ends the main process.

[0183] The user arranges the cable 19 above the guide member 8A in order to attach the cable 19 for attaching and winding the label 10A to the label winding device 1A. As shown in FIGS. 43(A) and 43(B), the user moves the cable 19 downward along the inclined surface 81A of the guide member 8A (arrow Y71). The cable 19 contacts the rib 53 of the opening / closing member 5 in the process of being guided by the guide member 8A toward the insertion part 62A of the attaching mechanism 6. An external force is applied to the lower end part of the opening / closing member 5. The opening / closing member 5 moves from the closed position toward the open position against the biasing force of the biasing part 56 (arrow Y73). Further, in response to the cable 19 contacting the first inclined part 711 of the first clamping member 71, as shown in FIG. 37, the protruding part 71D pushes the protruding part 51D of the opening / closing member 5 backward. The opening / closing member 5 moves further from the closed position toward the open position. Thereby, the opening 620B of the attaching mechanism 6 is switched from the state closed by the opening / closing member 5 (see FIG. 43(A)) to the open state (see FIG. 43(B)). Thereafter, the cable 19 is attached to the upper surface, that is, the adhesive surface Ur, of the label 10A arranged at the attachable position by the support part 32.

[0184] As shown in FIG. 43(C), the user further moves the cable 19 downward (arrow Y75). At this time, as shown in FIG. 27, the first pressing member 77 and the second pressing member 78 of the pressing member 76 positioned below the label 10A sandwich the label 10A between them and the cable 19, and support the label 10A from the opposite surface Us side. As the user further moves the cable 19 downward, as shown in FIG. 29, the first pressing member 77 and the second pressing member 78 contact the opposite surface Us of the label 10A from both the front and rear sides, and press the label 10A against the cable 19.

[0185] As shown in FIG. 43(D), thereafter, the cable 19 passes through the opening 620B and enters the insertion portion 62A of the sticking mechanism 6 from above, and moves within the insertion portion 62A from the opening 620B to the bottom 620A (arrow Y77). The cable 19 is clamped by the first clamping member 71 and the second clamping member 72 (see FIG. 33) of the holding member 7, and the first arm member 66 and the second arm member 67 of the sticking mechanism 6, and is held at the winding position Pm. Also, since the label 10A is in a state of being stuck to the cable 19, the label 10A is also inserted into the insertion portion 62A of the sticking mechanism 6 as the cable 19 moves.

[0186] As shown in FIG. 16, the clutch C1 interposed between the rotation shaft 302K of the second roller 302 and the gear 366A in the transmission portion 3B is in a state of blocking the rotation shaft 302K and the gear 366A, and the clutch C3 interposed between the rotation shaft 302K of the second roller 302 and the gear 366B is in a state of blocking the rotation shaft 302K and the gear 366B. Therefore, even if the label 10A moves to the downstream side in the conveying direction Y2 as the cable 19 is inserted into the insertion portion 62A, the movement is not hindered by the transmission portion 3B.

[0187] As shown in FIG. 43(D), with the cable 19 held at the winding position Pm, the label 10A is interposed between the first arm member 66 and the second arm member 67 and the cable 19. The label 10A is wound and stuck in a state covering approximately the lower half region of the cable 19.

[0188] As shown in FIG. 42, the CPU 91A determines whether both of the sensors Sw1 and Sw2 (see FIG. 4 and the like) have detected the cable 19 based on the signals output from the sensors Sw1 and Sw2 (S31). If neither of the sensors Sw1 and Sw2 has detected the cable 19, it means that the cable 19 has not reached the bottom 620A of the insertion portion 62A and is not arranged at the winding position Pm. Also, if only one of the sensors Sw1 and Sw2 has detected the cable 19 and the other has not, it means that the cable 19 is inclined in the left-right direction and the cable 19 is not arranged normally at the winding position Pm.

[0189] Therefore, when at least one of the sensors Sw1 and Sw2 has not detected the cable 19 (S31: NO), the CPU 91A advances the process to S51. The CPU 91A determines whether only one of the sensors Sw1 and Sw2 has detected the cable 19 (S51). When neither of the sensors Sw1 and Sw2 has detected the cable 19 (S51: NO), the CPU 91A returns the process to S31 and continues to monitor the signals output from the sensors Sw1 and Sw2.

[0190] On the other hand, when the CPU 91A determines that only one of the sensors Sw1 and Sw2 has detected the cable 19 (S51: YES), it determines whether a predetermined time has elapsed since the timing when it was first determined that only one of the sensors Sw1 and Sw2 has detected the cable 19 (S53). When the CPU 91A determines that the predetermined time has not elapsed (S53: NO), it returns the process to S31 and continues to monitor the signals output from the sensors Sw1 and Sw2. On the other hand, when the CPU 91A determines that the predetermined time has elapsed since the timing when it was first determined that only one of the sensors Sw1 and Sw2 has detected the cable 19 (S53: YES), it notifies the user through the notification unit 93A that the cable 19 is not properly installed (S55). The CPU 91A returns the process to the main process (see FIG. 41).

[0191] On the one hand, when both sensors Sw1 and Sw2 detect cable 19, cable 19 is arranged at winding position Pm at each of the two positions of sensors Sw1 and Sw2, so it is normally arranged at winding position Pm. When CPU91A determines that both sensors Sw1 and Sw2 have detected cable 19 (S31: YES), the process proceeds to S33. Note that while the pasting mechanism 6 rotates and label 10A is wound around cable 19 by the processes of S33 to S41 described later, cable 19 is maintained in a state of being held by holding member 7 at a position outside the left - right direction of pasting mechanism 6.

[0192] CPU91A controls drive circuit MC and rotates motor Mp3 so that pasting mechanism 6 rotates in the first rotation direction Y81 (see Fig. 43(E)) (S33). Based on the signal output from sensor Sw5, CPU91A rotates pasting mechanism 6 by a predetermined first predetermined amount (rotation angle), and then stops the rotation of pasting mechanism 6 (S35).

[0193] As shown in Fig. 43(E), when pasting mechanism 6 rotates in the first rotation direction Y81, the portion of label 10A between the pasting position with cable 19 and end portion 105 is wound around and pasted to cable 19 by first clamping member 71.

[0194] As shown in Fig. 42, next, CPU91A controls drive circuit MC and rotates motor Mp3 so that pasting mechanism 6 rotates in the second rotation direction Y83 (see Fig. 43(F)) (S37). Based on the signal output from sensor Sw5, CPU91A rotates pasting mechanism 6 by a predetermined second predetermined amount (rotation angle) that is larger than the first predetermined amount, and then stops the rotation of pasting mechanism 6 (S41). After that, CPU91A returns the process to the main process (see Fig. 41).

[0195] As shown in Fig. 43(F), when pasting mechanism 6 rotates in the second rotation direction Y83, the portion of label 10A between the pasting position with cable 19 and end portion 106 is wound around and pasted to cable 19 by first clamping member 71 and second clamping member 72.

[0196] Note that the cable 19 with the label 10A wound and attached thereto is moved upward from the winding position Pm in order to be detached from the label winding device 1A. The cable 19 passes through the opening 620B in the open state by the opening / closing member 5 disposed at the open position, and is taken out from the insertion portion 62A. After the cable 19 exits, the first clamping member 71 rotates counterclockwise by the biasing force of the biasing portion 73, and the second clamping member 72 rotates clockwise by the biasing force of the biasing portion 73, and each returns to its original position. Further, the opening / closing member 5 moves from the open position to the closed position by the biasing force of the biasing portion 56, and closes the opening 620B of the insertion portion 62A of the pasting mechanism 6.

[0197] <Tape replacement process> Referring to FIG. 44, the process during tape replacement will be described. The process during tape replacement is started when the CPU 91A reads and executes a program stored in the flash memory 91D when any operation is input to the operation unit 120A. Since the first cover 121 is in the closed state, the fourth roller 304 is disposed at the clamping position close to the first roller 301.

[0198] First, the CPU 91A determines whether an operation for starting the replacement of the tape cassette TC has been input to the operation unit 120A (S170). If the CPU 91A determines that an operation different from the operation for starting the replacement of the tape cassette TC has been input (S170: NO), the process during tape replacement is terminated. If the CPU 91A determines that an operation for starting the replacement of the tape cassette TC has been input (S170: YES), the process proceeds to S171.

[0199] The CPU 91A controls the drive circuit MC to rotate the motor Mp3. Thereby, the full-cut cutting blade 23 fully cuts the tape 10 disposed in the conveyance path R1 (S171, see FIG. 51(A)). Hereinafter, the end portion of the cut tape 10 is referred to as "cut end portion 107".

[0200] Next, the CPU 91A determines whether the peeling portion 4A and the conveyance guide 4B are arranged at the second position (S172). When the CPU 71A determines that the peeling portion 4A and the conveyance guide 4B are arranged at the first position (S172: NO), the process proceeds to S175. When the CPU 91A determines that the peeling portion 4A and the conveyance guide 4B are arranged at the second position (S172: YES), it controls the drive circuit MC to rotate the motor Mw1 to arrange the peeling portion 4A and the conveyance guide 4B at the first position (S173, see FIGS. 14 and 51(B)).

[0201] The CPU 91A controls the drive circuit MC to reversely drive the motor Mw2. In this case, as shown in FIG. 18, the first roller 301 and the second roller 302 rotate counterclockwise, and the third roller 303 rotates clockwise (S175). The tape 10 cut by the process of S173 is conveyed in the conveyance direction Y4 along the conveyance path R4 in response to the clockwise rotation of the third roller 303. Thereby, a part including the leading end portion of the tape 10 is accommodated in the paper discharge and storage portion 16.

[0202] The CPU 91A determines whether the cut end portion 107, which is the upstream end portion of the tape 10 in the conveyance direction Y4, has passed through the third roller 303 and reached the position Ps2 on the downstream side of the third roller 303 in the conveyance direction Y4. When the number of rotations of the motor Mw2 after starting the reverse drive of the motor Mw2 by the process of S175 is less than the third specified number, the CPU 91A determines that the cut end portion 107 of the tape 10 has not reached the position Ps2 (S177: NO), and returns the process to S177.

[0203] When the rotational speed of the motor Mw2 becomes equal to or higher than the third specified number after the CPU 91A starts the reverse drive of the motor Mw2 by the process of S175, it is determined that the cut end portion 107 of the tape 10 has reached the position Ps2 (S177: YES, see FIG. 51(C)). In this case, the tape 10 is not held by any member and is in a state where it can be easily removed from the conveyance path R4. The CPU 91A controls the drive circuit MC to stop the reverse drive of the motor Mw2 started in the process of S175 (S179). Thereby, the rotations of the first roller 301, the second roller 302, and the third roller 303 stop.

[0204] The CPU 91A turns on the tape replacement LED of the notification unit 93A (S181). When the user confirms the lighting of the tape replacement LED, the user opens the second cover 122 and removes the tape cassette TC from the tape storage unit 2A. The CPU 91A determines whether or not the tape cassette TC has been removed from the tape storage unit 2A based on the signal output from the sensor Sp2 (S183). When the tape cassette TC has not been removed from the tape storage unit 2A (S183: YES), the CPU 91A returns the process to S183 and continues lighting the tape replacement LED.

[0205] When the tape cassette TC has been removed from the tape storage unit 2A (S183: NO), the CPU 91A determines whether or not the cut end portion 107 of the tape 10 is at the position Ps2 based on the signal output from the sensor Sw2 (S185). When the user has not taken out the release material 10B from the paper discharge storage unit 16, the cut end portion 107 of the tape 10 is at the position Ps2. When the sensor Sw2 detects the tape 10 (S185: YES), the CPU 91A returns the process to S185 and continues lighting the tape replacement LED. When the release material 10B has been taken out from the paper discharge storage unit 16 (S185: NO), the CPU 91A turns off the tape replacement LED (S187).

[0206] When an input operation indicating that the mounting of the tape cassette TC is completed is input via the operation unit 120A, CPU 91A determines whether a signal indicating that the second cover 122 is closed is output from the sensor Sp1 and whether a signal indicating that a new tape cassette TC is mounted in the tape storage unit 2A is output from the sensor Sp2 (S189). If the tape cassette TC is not mounted in the tape storage unit 2A (S189: NO), CPU 91A returns the process to S189 and waits. The user mounts a new tape cassette TC in the tape storage unit 2A and closes the second cover 122. When CPU 91A determines that the second cover 122 is closed and a new tape cassette TC is mounted in the tape storage unit 2A (S189: YES), it controls the drive circuit MC to rotate the motor Mp2 and moves the platen holder 22 from the standby position to the printing position. As a result, the platen roller 22A approaches the thermal head 21, and the tape sub-roller 22B approaches the drive roller Ts of the tape cassette TC.

[0207] CPU 91A controls the drive circuit MC to reversely drive the motor Mw2 (S191). The first roller 301 sandwiches the tape 10 fed out from the tape cassette TC between itself and the fourth roller 304 and conveys it in the conveyance direction Y1 along the conveyance path R1 (see FIG. 14). CPU 91A waits until the leading end of the tape 10 reaches the position Ps2 based on the signal output from the sensor Sw2 (S193: NO). When CPU 91A determines that the leading end of the tape 10 has reached the position Ps2 (S193: YES), it controls the drive circuit MC to stop the reverse drive of the motor Mw2 (S195). As a result, the rotation of the first roller 301, the second roller 302, and the third roller 303 stops. Since the leading end of the tape 10 has reached the position Ps2, the third roller 303 is in a state of sandwiching the tape 10 between itself and the driven roller 323. That is, the tape 10 can be conveyed by the rotation of the third roller 303. CPU 91A ends the tape replacement process.

[0208] <Processing in case of malfunction> Referring to FIG. 45, the processing during malfunction will be described. The processing during malfunction is started when the CPU 91A reads and executes the program stored in the flash memory 91D during the execution of the main processing (refer to FIGS. 41 to 42). The main processing and the processing during malfunction are executed in parallel.

[0209] First, after the peeling of the label 10A by the peeling portion 4A and the conveyance of the label 10A by the second roller 302 are started by the processing of S151 (refer to FIG. 41) in the main processing, the CPU 91A determines whether the label 10A is detected at the position Ps1 on the downstream side in the conveyance direction Y2 of the second roller 302 in the conveyance path R2 based on the signal output from the sensor Sw1 (refer to FIG. 8) (S201). If the CPU 91A determines that the label 10A is not detected at the position Ps1 for a predetermined first time or more after the peeling of the label 10A by the peeling portion 4A is started (S201: NO), it determines that a jam has occurred in the label 10A in the peeling portion 4A (S203).

[0210] The CPU 91A temporarily stops the ongoing print control in the main processing (FIGS. 40, 41) (S204). The CPU 91A identifies, in the main processing (FIGS. 40, 41), the image printed immediately before the jam of the label 10A as the image printed on the jammed label 10A (S205). The CPU 91A notifies, via the notification unit 93A, that a jam has occurred in the label 10A in the peeling portion 4A (S207).

[0211] Next, the CPU 91A determines whether the first cover 121 has been opened or closed based on the signal output from the sensor Sw6 (S209). If the CPU 91A determines that the first cover 121 has not been opened or closed (S209: NO), the process returns to S209. Here, in order for the user to eliminate the clogging of the label 10A in the peeling portion 4A, the user opens the first cover 121, removes the clogged label 10A from the peeling portion 4A, and then closes the first cover 121. If the CPU 91A determines that the first cover 121 has been opened or closed (S209: YES), the process proceeds to S221. The CPU 91A reprints the image of the label 10A identified by the process of S205 and resumes the print control in the main process (S221). The CPU 91A ends the malfunction handling process.

[0212] On the other hand, if the CPU 91A detects the label 10A at the position Ps1 before the first hour has elapsed since the peeling of the label 10A by the peeling portion 4A was started by the process of S151 (see FIG. 41) in the main process (S201: YES), the CPU 91A determines whether the label 10A has been continuously detected at the position Ps1 for a predetermined second hour or more based on the signal output from the sensor Sw1 (S231). If the CPU 91A determines that the label 10A has been continuously detected at the position Ps1 for the second hour or more since the label 10A was first detected (S231: YES), the CPU 91A determines that a clogging of the label 10A has occurred in the sticking mechanism 6 (S233).

[0213] The CPU 91A temporarily stops the ongoing print control in the main process (FIGS. 40 and 41) (S234). The CPU 91A identifies, as the image printed on the clogged label 10A, the image printed immediately before the clogging of the label 10A occurred in the main process (FIGS. 40 and 41) (S235). The CPU 91A notifies, via the notification unit 93A, that a clogging of the label 10A has occurred in the sticking mechanism 6 (S237).

[0214] Next, the CPU 91A determines whether the third cover 123 has been opened or closed based on the signal output from the sensor Sw7 (S239). If the CPU 91A determines that the third cover 123 has not been opened or closed (S239: NO), the process returns to S239. Here, the user opens the third cover 123 to remove the jammed label 10A from the pasting mechanism 6 in order to eliminate the jam of the label 10A in the pasting mechanism 6, and then closes the third cover 123. If the CPU 91A determines that the third cover 123 has been opened or closed (S239: YES), the process proceeds to S221. The CPU 91A reprints the image of the label 10A specified by the process of S235 and resumes the printing control in the main process (S221). The CPU 91A ends the malfunction processing.

[0215] <Actions and effects of this embodiment>

[0216] By providing the paper discharge and storage unit 16 inside the housing 11, the label winding device 1A can easily collect the peeling material 10B remaining after peeling the label 10A from the tape 10, and can reduce the size of the device configuration.

[0217] By pulling out the peeling material 10B with the third roller 303 and feeding it to the peeling unit 4A, the peeling guide mechanism 4 can peel the tape 10 more reliably, and by feeding the peeling material 10B after peeling toward the paper discharge and storage unit 16, the peeling material 10B can be more reliably stored in the paper discharge and storage unit 16.

[0218] In the label winding device 1A, the storage area 11A and the mounting area 11B communicate with each other, and a part of the tape storage unit 2A that communicates with the paper discharge and storage unit 16 is used as the paper discharge and storage unit 16, and by making the paper discharge and storage unit 16 have a larger capacity, the peeling material 10B after peeling the label 10A can be easily collected. In addition, since the area of the wall portion provided when partitioning the paper discharge and storage unit 16 and the tape storage unit 2A can be effectively used, the label winding device 1A can reduce the size of the device configuration.

[0219] The label winding device 1A can also accommodate the release material 10B stored in the paper discharge storage section 16 through the communication portion with the tape storage section 2A in a partial area of the tape storage section 2A. Therefore, by making the paper discharge storage section 16 have a larger capacity, the label winding device 1A can easily collect the release material 10B after the label 10A is peeled off.

[0220] When the first cover 121 is opened for maintenance or the like, the holding of the release material 10B by the third roller 303 is mechanically released, so that the user can easily take out the release material 10B.

[0221] When the first cover 121 is opened for maintenance or the like, the holding of the tape 10 by the first roller 301 is released in conjunction, so that the user can easily take out the tape 10 and the release material 10B.

[0222] The inclined portion 16F can guide the release material 10B to the paper discharge storage section 16 and accommodate the release material 10B in the paper discharge storage section 16 while curling the release material 10B.

[0223] The roller 16B can guide the release material 10B to the paper discharge storage section 16 and accommodate the release material 10B in the paper discharge storage section 16 while curling the release material 10B.

[0224] The paper discharge storage section 16 functions as an empty chamber for storing the release material 10B sent out from the peeling guide mechanism 4. For example, a winding roller for winding the release material 10B is not installed. Therefore, the label winding device 1A can achieve miniaturization of the device configuration.

[0225] When the cutting section 2C cuts the tape 10, the tape 10 before peeling and the release material 10B after peeling, which are downstream of the cutting section 2C, are separated from the original tape 10. Therefore, the user can easily collect the release material 10B stored in the paper discharge storage section 16.

[0226] By detecting the presence or absence of the release material 10B on the downstream side of the third roller 303 with the sensor Ps2, it is possible to confirm whether the release material 10B is properly sent to the conveyance path R3 leading to the paper discharge storage section 16.

[0227] When the user inputs an exchange instruction to the operation unit 120A during the tape 10 exchange, the tape 10 before the peeling of the label 10A and the peeled material 10B after peeling, which are located downstream of the cutting unit 2C, are separated from the original tape 10. Therefore, it is easy for the user to collect the peeled material 10B stored in the paper discharge storage unit 16.

[0228] When the user inputs an exchange instruction to the operation unit 120A during the tape 10 exchange, the tape 10 before the peeling of the label 10A and the peeled material 10B after peeling, which are cut by the cutting unit 2C, are conveyed by a predetermined length, and the rear end is located downstream of the third roller 303. Therefore, it is easy for the user to collect the peeled material 10B stored in the paper discharge storage unit 16.

[0229] Immediately after the user inputs an exchange instruction to the operation unit 120A during the tape 10 exchange, the cutting unit 2C, the peeling guide mechanism 4, etc. are driving. Therefore, if the user exchanges the tape 10, the tape 10 may become jammed. By lighting the tape exchange LED of the notification unit 93A, it is possible to notify the user of the timing when the tape 10 can be exchanged.

[0230] The notification unit 93A continues to display the tape exchange LED until not only the tape 10 is removed from the tape storage unit 2A but also the peeled material 10B is collected from the paper discharge storage unit 16. Therefore, the label winding device 1A can prevent the user from forgetting to collect the peeled material 10B during the tape 10 exchange.

[0231] When the user exchanges the tape cassette TC, there may be a case where the user exchanges the tape cassette TC before taking out the peeled material 10B from the paper discharge storage unit 16. Therefore, the CPU 91A can turn off the tape exchange LED if the peeled material 10B is taken out after the tape cassette TC before the exchange is taken out from the tape storage unit 2A during the tape exchange.

[0232] Before the tape cassette TC is replaced, the peeling material 10B discharged is half-cut and stored in the paper discharge storage unit 16 in a state where it is connected without being cut. Therefore, if the user takes out the peeling material 10B from the paper discharge storage unit 16, the cut end portion 107 of the cut tape 10 is also taken out from the conveyance path R3, so the CPU 91A can turn off the tape replacement LED in the notification unit 93A.

[0233] <Modification Example> The present invention is not limited to the above-described embodiment, and various modifications are possible. The printing method by the printing unit 2B is not limited to the above-described embodiment. For example, the label winding device 1A may perform printing using a receptor type tape cassette TCR. In this case, the tape cassette TCR stores a tape 700 (see FIG. 52) in which a base material and a peeling material 710B adhered to an adhesive surface to which an adhesive is applied among the base materials are laminated, and an ink ribbon Ir. The printing unit 702B performs printing on the opposite surface of the tape 700 opposite to the adhesive surface. Note that, as the base material, for example, a die-cut label previously cut to a predetermined size may be used for the tape 700.

[0234] When using a receptor type tape cassette TCR, as shown in FIG. 52, the label winding device 701 arranges the peeling guide mechanism 704, the cutting unit 702C, and the conveyance path R3 in a direction inverted in the vertical direction inside the housing 712. Depending on the layout of each mechanism, there may be a space provided between the tape storage unit 702A and the bottom wall 712A of the housing 712. The paper discharge storage unit 716 is provided using the empty space below the tape storage unit 702A in the housing 712. The paper discharge storage unit 716 is configured to communicate with the tape storage unit 702A. With this configuration, when the second cover 122 is opened, the tape storage unit 702A and the paper discharge storage unit 716 can be opened, and similarly to this embodiment, the user can easily take out the peeling material 710B.

[0235] Therefore, the label winding device 701 can use the empty space between the tape storage portion 702A for mounting the tape cassette TCR in the housing 712 and the bottom wall 712A of the housing 712 as the discharge paper storage portion 716 for the release material 710B. Therefore, since the label winding device 701 can effectively utilize the space within the housing 712, miniaturization of the device configuration can be achieved.

[0236] The label winding device 1A may not have the printing unit 2B and the cutting unit 2C. Printing on the tape 10 may be performed by an external printing device. The label winding device 1A may use the tape 10 printed by the printing device and wind and attach the label to the cable 19. The object to which the label 10A is attached is not limited to the cable 19 and may be other adherends.

[0237] The label winding device 1A may not have the driven roller 312. The second roller 302 may convey the label 10A alone in the conveying direction Y2. The label winding device 1A may not have the driven roller 324. The third roller 303 may convey the release material 10B alone in the conveying direction Y3. Also, the third roller 303 may convey the tape 10 alone in the conveying direction Y4.

[0238] The positions where the operation units 120A and 120B are provided with respect to the housing 11 are not limited to the above-described embodiment and may be provided at other parts (for example, the left and right side surfaces and the rear surface of the housing 11). The support portion 32 may be provided outside the passage region 300A. For example, the support portion 32 may be provided on the restricting portion 8B.

[0239] The mechanism for conveying the label 10A at the position of the second roller 302 and the mechanism for conveying the release material 10B and the tape 10 at the position of the third roller 303 are not limited to rollers and may be other mechanisms (for example, a belt conveyor).

[0240] The label winding device 1A may separately have a cover that can open and close the passing area 300A of the label 10A and the passing area 300B of the release material 10B. The label winding device 1A may separately have a cover that can open and close the passing area 300A of the label 10A and the passing area 300B of the release material 10B, and a cover that can open and close the peeling part 4A. The label winding device 1A may separately have a cover that can open and close the tape storage part 2A and a cover that can open and close the cutting part 2C. The opening directions of the first opening 121S when the first cover 121 is open and the second opening 122A when the second cover 122 is open may coincide. For example, both the first opening 121S and the second opening 122A may open to the right.

[0241] The lever 31S swings according to the opening and closing of the first cover 121, and switches the fourth roller 304 between the clamping position (see FIG. 14) and the separated position (see FIG. 11). In contrast, for example, the lever 31S may be manually operable by the user. That is, the user may be able to manually switch between the state where the fourth roller 304 is arranged in the clamping position and the state where it is arranged in the separated position.

[0242] The label winding device 1A is configured without a partition wall between the paper discharge storage part 16 and the tape storage part 2A, but a partition wall may be provided in part to prevent the release material 10B from entering the drive part and the printing part 2B. By communicating the area between the mounting area 11B and the bottom wall of the housing 11 and also communicating with the storage area 11A, the release material 10B may be able to be stored in a larger area. The roller 16B may not be provided.
