<Schematic configuration of adhesive tape printer>
First, a schematic configuration of the pressure-sensitive adhesive tape printer according to the present embodiment will be described with reference to FIGS.

  1 to 6, the adhesive tape printer 1 according to the present embodiment includes a housing 2, a rear side opening / closing part 8, and a front side opening / closing cover 9 that form the outer shell of the apparatus.

  The housing 2 includes a housing main body 2a, a first storage portion 3 (storage portion) provided on the rear side of the housing main body 2a, a second storage portion 4 provided on the front side of the housing main body 2a, and And a third storage unit 5. The first storage unit 3, the second storage unit 4, and the third storage unit 5 will be described in detail later.

  The rear side opening / closing part 8 is connected to the upper part on the rear side of the housing body 2a so as to be openable and closable. The rear opening / closing part 8 can be opened and closed above the first storage part 3 by rotating. The rear opening / closing part 8 is composed of a first opening / closing cover 8a and a second opening / closing cover 8b.

  The first opening / closing cover 8a can be opened / closed above the front side of the first storage unit 3 by rotating around a predetermined rotation axis K1 provided at the upper part on the rear side of the housing body 2a. is there. Specifically, the first opening / closing cover 8 a exposes the upper front side of the first storage unit 3 from the closed position (the state shown in FIGS. 1 to 3) covering the upper side of the first storage unit 3. It can be rotated between the opening positions (the state shown in FIGS. 4 and 5). At this time, the rotational axis K1 of the first opening / closing cover 8a is located behind the roll center RO of a later-described first roll R1 (printed tape roll) whose position in the front-rear direction is stored in the first storage unit 3. And the position in the vertical direction is above the roll center RO.

  A head holder 10 is provided inside the first opening / closing cover 8a (see FIG. 4). The first opening / closing cover 8a is rotated about the rotation axis K1 to thereby transfer a print head 11 (described later) provided in the head holder 10 (described later) provided in the housing body 2a. The roller 12 can be relatively separated from and close to the roller 12. Specifically, the first opening / closing cover 8a is opened from the closed position (the state shown in FIG. 2) in which the print head 11 is close to the conveying roller 12 (the state shown in FIG. 2). ).

  The second opening / closing cover 8b is provided on the rear side of the first opening / closing cover 8a, and rotates around a predetermined rotation axis K2 provided at the upper end portion on the rear side of the housing body 2a. Thus, the rear upper side of the first storage part 3 can be opened and closed separately from the opening and closing of the first opening and closing cover 8a. Specifically, the second opening / closing cover 8b exposes the rear upper part of the first storage part 3 from the closed position (the state shown in FIGS. 1 and 2) covering the upper part of the first storage part 3 on the rear side. It can be rotated between the open position (state shown in FIGS. 3 to 5). At this time, the rotation axis K2 of the second opening / closing cover 8b is located further rearward than the rotation axis K1 of the first opening / closing cover 8a, and the position in the vertical direction is the rotation axis. It is further above the heart K1. Note that the vertical position of the rotation axis K2 of the second opening / closing cover 8b may be the same as the rotation axis K1 of the first opening / closing cover 8a.

  When the first opening / closing cover 8a and the second opening / closing cover 8b are in the closed state, the outer peripheral portion 18 of the first opening / closing cover 8a and the edge 19 of the second opening / closing cover 8b are substantially the same. It is configured to contact and cover substantially the entire upper part of the first storage unit 3.

  The front opening / closing cover 9 is connected to the upper part on the front side of the housing body 2a so as to be openable and closable. The front opening / closing cover 9 can be opened and closed above the second storage portion 4 by rotating around a predetermined rotation axis K3 provided at the upper end on the front side of the housing body 2a. Specifically, the front opening / closing cover 9 is opened from the closed position (the state shown in FIGS. 1 to 4) that covers the upper side of the second storage part 4 to expose the upper side of the second storage part 4 (the state shown in FIG. 5). ).

  At this time, an adhesive tape cartridge TK (tape cartridge) is detachably mounted at a first predetermined position 13 below the front opening / closing cover 9 in the closed state of the housing body 2a. The adhesive tape cartridge TK includes a first roll R1, a third roll R3, and a connecting arm 16 that connects the first roll R1 and the third roll R3.

  The first roll R1 is supported on the rear side of the adhesive tape cartridge TK by the connecting arm 16, and is rotatable when the adhesive tape cartridge TK is attached to the housing body 2a. The first roll R1 is wound around the axial center O1 in the left-right direction in advance with the print-receiving adhesive tape 150 consumed by feeding. At this time, when the adhesive tape cartridge TK is mounted, the first roll R1 is received from above and is stored in the first storage unit 3 in a state where the axis O1 of the wound adhesive tape 150 is in the left-right direction. The And the 1st roll R1 is a predetermined rotation direction (A direction in FIG. 2) in the said 1st accommodating part 3 in the state accommodated in the 1st accommodating part 3 (state in which adhesive tape cartridge TK was mounted | worn). The printed adhesive tape 150 is fed out. As for the to-be-printed adhesive tape 150, the base material layer 153, the adhesive layer 152, and the release material layer 151 are arranged in the thickness direction from one side (upper side in the partial enlarged view in FIG. 2) to the other side (part in FIG. They are laminated in this order toward the lower side in the enlarged view). The base material layer 153 is a layer on which a desired print is formed by the print head 11 described later. The pressure-sensitive adhesive layer 152 is a layer for attaching the base material layer 153 to an appropriate adherend (not shown). The release material layer 151 is a layer that covers the pressure-sensitive adhesive layer 152.

  Further, a conveyance roller 12 is provided on the middle upper side of the first storage unit 3 and the third storage unit 5 in the housing body 2a. The transport roller 12 is driven through a gear mechanism (not shown) by a transport motor M1 provided in the housing body 2a, so that the transport roller 12 is fed from the first roll R1 stored in the first storage unit 3. The printing adhesive tape 150 is conveyed in a tape posture in which the tape width direction is the left-right direction.

  The head holding unit 10 provided on the first opening / closing cover 8a is provided with a print head 11. As described above, the print head 11 can be relatively separated from and brought close to the transport roller 12 by the first opening / closing cover 8a rotating about the rotation axis K1. That is, when the first opening / closing cover 8a is in the closed state, the print head 11 comes close to the conveying roller 12, and when the first opening / closing cover 8a is in the opened state, the printing head 11 is separated from the conveying roller 12. The print head 11 is conveyed by the first opening / closing cover 8a in the closed state of the head holding unit 10 so as to sandwich the print-receiving adhesive tape 150 conveyed by the conveyance roller 12 in cooperation with the conveyance roller 12. The roller 12 is disposed at a position facing the upper side. Therefore, when the first opening / closing cover 8a is in the closed state, the print head 11 and the transport roller 12 are arranged to face each other in the vertical direction. The print head 11 forms a desired print on the base material layer 153 of the print-targeted adhesive tape 150 sandwiched between the conveyance rollers 12 by using an ink ribbon IB of a ribbon cartridge RK described later. Thus, the printed adhesive tape 150 ′ is obtained.

  At this time, the ribbon cartridge RK is detachably mounted at the second predetermined position 14 below the first opening / closing cover 8a and above the adhesive tape cartridge TK in the closed state of the housing body 2a. The ribbon cartridge RK includes a ribbon supply roll R4 and a ribbon take-up roll R5.

  The ribbon supply roll R4 is rotatably supported on the rear side of the ribbon cartridge RK. When the ribbon cartridge RK is mounted, the ribbon supply roll R4 rotates in a predetermined rotation direction (D direction in FIG. 2), thereby 11, the ink ribbon IB for printing is formed.

  The ribbon take-up roll R5 is rotatably supported on the front side of the ribbon cartridge RK. When the ribbon cartridge RK is mounted, the ribbon take-up roll R5 rotates in a predetermined rotation direction (E direction in FIG. 2), thereby printing. The used ink ribbon IB after formation is wound up.

  A ribbon take-up roller 15 is provided on the downstream side of the print head 11 along the tape transport direction in the first opening / closing cover 8a. The ribbon take-up roller 15 guides the used ink ribbon IB to the ribbon take-up roll R5.

  That is, the ink ribbon IB fed out from the ribbon supply roll R4 is disposed further on the print head 11 side of the print-receiving adhesive tape 150 sandwiched between the print head 11 and the transport roller 12, and below the print head 11. To touch. Then, after the ink from the ink ribbon IB is transferred to the base material layer 153 of the print-receiving adhesive tape 150 by the heating from the print head 11 and the print formation is executed, the used ink ribbon IB is transferred to the ribbon take-up roller. 15 is wound around the ribbon take-up roll R5 while being guided by the belt 15.

  The connecting arm 16 includes a peeling portion 17 including, for example, a substantially horizontal slit shape on the upstream side of the third roll R3 along the tape transport direction. The peeling part 17 is a part where the peeling material layer 151 is peeled off from the printed adhesive tape 150 ′ (printed tape) that is fed from the first roll R 1 and conveyed forward. When the release material layer 151 is peeled off from the printed adhesive tape 150 ′ by the peeling portion 17, the release adhesive layer 151 and the printed adhesive tape 150 ″ including the other base material layer 153 and the adhesive layer 152 are provided. The peeled release material layer 151 is wound up and wound to form the third roll R3, and the printed adhesive with the release material layer 151 peeled off. The second roll R2 (printed tape roll), which will be described later, is formed by winding the tape 150 "on the outer peripheral side of the core member 40, which will be described later.

  The third roll R3 is supported by the connecting arm 16 on the front side of the adhesive tape cartridge TK (that is, on the downstream side of the first roll R1 along the tape transport direction). In a state where the adhesive tape cartridge TK is mounted on the housing body 2a, the third roll R3 is rotatable, and the release material layer 151 peeled off from the printed adhesive tape 150 'is placed in the horizontal axis O3 (axis). Wrap around. At this time, the third roll R3 is received from above by the attachment of the adhesive tape cartridge TK and is stored in the third storage portion 5 in a state where the axis O3 of the winding of the release material layer 151 is in the left-right direction. . The third roll R3 is a release paper winding motor M3 (second winding) provided in the housing body 2a in a state where the third roll R3 is stored in the third storage unit 5 (a state where the adhesive tape cartridge TK is mounted). The motor is driven by a gear mechanism (not shown) and rotated in a predetermined rotation direction (C direction in FIG. 2) in the third storage unit 5 to wind up the release material layer 151. In addition, the structure of the connection arm 16 other than the above and the support structure of the first roll R1 and the third roll R3 will be described in detail later.

  In addition, the second storage unit 4 receives from above the core member 40 for winding the printed adhesive tape 150 ″ from which the release material layer 151 has been peeled off from the printed adhesive tape 150 ′. The wound adhesive tape 150 ″ is housed so as to be rotatably supported around the axis O2 in a state where the axis O2 (axis) of the wound adhesive tape 150 ″ is in the left-right direction. Then, in a state where the core member 40 is housed in the second housing portion 4, it is driven via a gear mechanism by an adhesive winding motor M2 (first winding motor) provided in the housing body 2a. The printed adhesive tape 150 ″ is wound and laminated by rotating in a predetermined rotation direction (direction B in FIG. 2) in the second storage portion 4. Thereby, on the outer peripheral side of the core member 40 The printed adhesive tape 150 ″ is sequentially wound to form the second roll R2. Further, a pressing roller 37 (tape pressing member) supported in a direction toward the outer peripheral surface of the second roll R2 via a predetermined biasing member is provided on the inner surface of the front opening / closing cover 9. When the outer diameter of the second roll R2 is sufficiently large, the tip of the pressing roller 37 is urged against and contacts the outer peripheral surface of the second roll R2. The configuration around the core member 40 and the axis O2 will be described in more detail later.

<Outline of operation of adhesive tape printer>
Next, an outline of the operation of the adhesive tape printer 1 will be described.

  That is, when the adhesive tape cartridge TK is mounted at the first predetermined position 13, the first roll R1 is stored in the first storage portion 3 located on the rear side of the housing body 2a, and on the front side of the housing body 2a. The third roll R3 is stored in the third storage portion 5 that is positioned. Moreover, the core member 40 for forming 2nd roll R2 is accommodated in the 2nd accommodating part 4 located in the front side of the housing body 2a.

  At this time, when the transport roller 12 is driven, the print-receiving adhesive tape 150 fed out by the rotation of the first roll R1 stored in the first storage unit 3 is transported forward. Then, a desired print is formed by the print head 11 on the base material layer 153 of the transported adhesive tape 150 to be conveyed, and a printed adhesive tape 150 ′ is obtained. When the printed adhesive tape 150 ′ that has been printed is further transported to the front side and transported to the peeling part 17, the release material layer 151 is peeled off at the peeling part 17. The peeled release material layer 151 is transported downward, introduced into the third storage unit 5, and wound in the third storage unit 5 to form a third roll R3.

  On the other hand, the printed adhesive tape 150 ″ from which the release material layer 151 has been peeled off is further conveyed forward and introduced into the second storage unit 4, and the outer peripheral side of the core member 40 in the second storage unit 4. In this case, the second roll R2 is formed on the front opening / closing cover 9 on the rear side of the second roll R2, that is, on the upstream side of the second roll R2 along the tape transport direction. The cutter mechanism 30 (cutting means) cuts the printed adhesive tape 150 ″ that has been printed and from which the release material layer 151 has been peeled off. Thereby, the printed adhesive tape 150 ″ wound around the second roll R2 at a timing desired by the user can be cut, and after the cutting, the second roll R2 can be taken out from the second storage section 4.

<Detailed structure of each part>
Next, the detailed structure of each part of the adhesive tape printer 1 will be described in order.

<Adhesive tape cut ridge>
6 and 7, the adhesive tape cartridge TK includes the first roll R1, the third roll R3, and the connecting arm 16, as described above. The connecting arm 16 includes a pair of left and right first bracket portions 20 and 20 provided on the rear side, and a pair of left and right second bracket portions 21 and 21 provided on the front side. In FIG. 7, the printed adhesive tape 150 wound around the axis O1 in the first roll R1 and the release material layer 151 wound around the axis O3 in the third roll R3 are illustrated. While omitted, some of the members constituting the first roll R1 and the third roll R3 are omitted.

  The first bracket portions 20 and 20 sandwich the first roll R1 from both the left and right sides along the axis O1, and the first roll R1 when the adhesive tape cartridge TK is attached to the housing body 2a. Is rotatably held around the axis O1. The first bracket portions 20 are connected to each other while avoiding interference with the outer diameter of the first roll R1 by a first connection portion 22 extending substantially along the left-right direction at the upper end portion.

  The second bracket portions 21 and 21 sandwich the third roll R3 from the left and right sides (one side and the other side) along the axis O3, and the adhesive tape cartridge TK is attached to the housing body 2a. In this state, the third roll R3 is rotatably held around the axis O3. The second bracket portions 21 and 21 are connected by a second connection portion 23 that extends substantially along the left-right direction at the upper end portion.

  The first bracket parts 20 and 20 and the first connection part 22 on the rear side, and the second bracket parts 21 and 21 and the second connection part 23 on the front side are a pair of left and right roll connection beam parts 24, 24 are connected.

  Here, as described above, when the adhesive tape cartridge TK is used, the printing adhesive tape 150 is consumed by being fed out and conveyed from the first roll R1. On the other hand, on the third roll R3, the release material layer 151 peeled off by the peeling portion 17 from the printed adhesive tape 150 ′ formed by printing the printed adhesive tape 150 is conveyed around the axis O3. Wound around.

  As a result of the above usage, when the tape roll freely rotates in the state of the adhesive tape cartridge TK alone before being attached to the housing, the tape may be loosened or loosened. In this case, when the adhesive tape cartridge TK is attached to the housing, it is necessary to eliminate the tape looseness and looseness, and the handling by the user is reduced.

  Therefore, in the present embodiment, as shown in FIGS. 8 to 10, the outer diameter D1 of the first shaft end R1a (both ends of the first core) provided on both axial sides of the first roll R1 is The dimension is set to be sufficiently smaller than the inner diameter D2 of the first shaft hole portion R1b inserted through each of the first bracket portions 20, 20. That is, each first shaft end R1a is loosely fitted to each first shaft hole R1b through a sufficient gap. The outer peripheral surface of each first shaft end R1a is provided with a plurality of outer peripheral projections 61 (second concavo-convex portions) at equal intervals throughout the entire circumferential direction, and each first shaft hole R1b On the inner peripheral surface, a plurality of inner peripheral protrusions 62 (first uneven portions) are provided at equal intervals over the entire circumferential direction. In this example, the outer peripheral side protrusions 61 and the inner peripheral side protrusions 62 are provided in the same number and the same protrusion height and shape.

  For example, when the adhesive tape cartridge TK is attached to the housing body 2a, the first shaft end R1a and the first shaft hole R1b are coaxially arranged as shown in FIG. In this state, the outer peripheral surface of the first shaft end R1a and the inner peripheral surface of the first shaft hole R1b are separated by the same gap over the entire circumferential direction, and the inner peripheral protrusion 62 and the outer peripheral protrusion The projecting height dimensions of the portions 61 are set so that they do not engage (interfer) with each other between the gaps. That is, the inner peripheral surface of the first shaft hole R1b and the outer peripheral surface of the first shaft end R1a can be in a state in which the inner peripheral protrusion 62 and the outer peripheral protrusion 61 are not engaged. It is comprised so that it may oppose to radial direction through a predetermined gap. For this reason, when the adhesive tape cartridge TK is attached to the housing body 2a, the first end R1a is rotatable in the first shaft hole R1b.

  Further, since the connecting arm 16 is structured to hold the first roll R1 in a suspended state, as shown in FIG. 9, when the adhesive tape cartridge TK is removed from the housing body 2a and lifted, the first arm R1 is pulled by gravity. Since one roll R1 moves relatively downward, the first shaft end R1a contacts the lower side of the first shaft hole R1b. Thereby, the inner peripheral side protrusion 62 and the outer peripheral side protrusion 61 are engaged, and the first roll R1 becomes non-rotatable.

  Also, as shown in FIG. 10, in the state where the adhesive tape cartridge TK is placed on a table or the like, the first roll R1 moves relatively upward, so that the first shaft end R1a is the first shaft hole R1b. Touch the upper side of the. Also by this, the inner peripheral side protrusion part 62 and the outer peripheral side protrusion part 61 are engaged, and the first roll R1 becomes non-rotatable.

  As described above, in the state of the adhesive tape cartridge TK alone before being attached to the housing main body 2a, the inner peripheral protrusion 62 and the outer protrusion 61 are engaged to make the first roll R1 non-rotatable. In the state where the adhesive tape cartridge TK is mounted on the housing body 2a, the inner peripheral protrusion 62 and the outer peripheral protrusion 61 are not engaged with each other, and the first roll R1 is allowed to rotate. Is possible. As a result, it is possible to prevent the tape from being loosened or loosened with the adhesive tape cartridge TK alone.

  Moreover, in the example of this embodiment, also in 2nd axial end R3a provided in the axial direction both sides of 3rd roll R3, and 2nd axial hole R3b each penetrated by each 2nd bracket part 21 and 21 respectively. The same support structure (outer peripheral side protrusion 61: fourth uneven portion, inner peripheral protrusion 62: third uneven portion) is provided. The enlarged views of FIGS. 8B, 9B, and 10B are the first shaft holes in FIGS. 8A, 9A, and 10A, respectively. It is shown in common to the support state of the portion R1b and the first shaft end portion R1a and the support state of the second shaft hole portion R1b and the second shaft end portion R1a.

<Detailed structure of cutter mechanism>
As shown in FIGS. 11, 12, and 13, the cutter mechanism 30 includes a guide plate 31, a movable blade 32, a traveling body 33 including a movable blade support portion 33 a that supports the movable blade 32, and a guide rail. 34.

  The guide plate 31 extends in the tape width direction on the inner side of the open edge side of the second opening / closing cover 4 on the downstream side in the tape transport direction from the transport roller 12. The guide plate 31 is supported by a pair of left and right support plates 35 a and 35 b with respect to the second opening / closing cover 4. And the guide plate 31 is the upper surface of the printed adhesive tapes 152 and 153 (in other words, the upper surface of the base material layer 153) which is conveyed by the conveying roller 12 in the housing 2 in a posture in which the tape width direction is the left-right direction. (Corresponding to the surface at one end in the vertical direction) and guide (refer to the imaginary lines in FIGS. 12 and 13).

  The movable blade 32 is arranged below the guide plate 31 so that the blade edge 32a faces the guide plate 31 in the vertical direction (in this example, the blade edge 32a faces upward). The movable blade 32 travels in the tape width direction along the guide plate 31 and cuts along the guide plate 31 by the traveling body 33 guided by the guide rail 34 and driven by the driving of the cutter motor M4 (arrow arrow in FIG. 12). reference). The guide rail 34 is supported by the pair of left and right support plates 35 a and 35 b with respect to the second opening / closing cover 4.

  The movable blade 32 holds the printed adhesive tapes 152, 153 between the guide plate 31 and the printed adhesive tapes 152, 153 while holding the printed adhesive tapes 152, 153 with the traveling of the traveling body 33 along the guide rail 34. It enters from the adhesive layer 152 of the lower layer (corresponding to the layer on the other side in the thickness direction) and performs the above cutting. At that time, the movable blade support portion 33a moves the movable blade 32 toward the traveling direction along the tape width, and the cutting edge 32a of the movable blade 32 (see FIG. 12) guides the printed adhesive tapes 152 and 153 to the guide plate. It supports with respect to the traveling body 33 so that it may incline in the direction pushed to 31 direction (in this example, it may become a downward inclination). As a result, the printed adhesive tapes 152 and 153 are obliquely arranged on the lower surface while the upper surface (specifically, the upper surface of the base material layer 153 after the print formation by the print head 11) is guided by being brought into contact with the guide plate 31. When the blade 32a of the upward movable blade 32 enters and is cut from the lowermost adhesive layer 152, it is cut in the width direction. At this time, a slit 31 a is formed in the guide plate 31 in the tape width direction so as to guide the traveling of the movable blade 32 by the traveling body 33.

  Note that, on the downstream side of the guide plate 31 along the tape transport direction, the transport path of the printed adhesive tapes 152 and 153 is switched between the side toward the second roll R2 and the side toward the discharge port 12. A chute 15 is provided for this purpose.

Two bearing portions 39, which are substantially cylindrical projections, are fixedly provided on both right sides so as to sandwich the second roll R2, respectively. By attaching the shaft end portions to the bearing portions 39, the central portion of the core member 40 is rotatably supported, as compared with the left bearing portion 39 in the second storage portion 4 of the housing body 2a. In the lower part on the rear side, it is linked to the adhesive take-up motor M2. A part of the tooth surface of the drive gear 38 is exposed toward the bearing portion 39. In FIG. 14 and FIG. 15, the second roll R2 is not shown, and in FIG. 150 ″ and the front opening / closing cover 9 are not shown.

  In FIG. 16, as will be described in detail later, the core member 40 is a central drum around which the printed adhesive tape 150 ″ is wound by connecting the shaft ends on both sides in the axial direction to form a small-diameter support shaft. The shaft 50 is configured to pass through the shaft center of the portion 50 and be rotatably supported (see FIG. 17 described later) The first outer cylinder 42 having a substantially annular flange on the outer periphery on the right side of the drum portion 50.

The first outer cylinder 42 and the second outer cylinder 42 are attached to the printed adhesive tape 150 ″ around which the core member 40 is wound. The outer cylinder 43 can be properly sandwiched in the width direction according to the tape width. That.

  At a predetermined circumferential position on the left end side of the core member 40, a detected part 81 whose exposure width changes according to the movement position of the second outer cylinder 43 is provided. The detected part 81 is formed in a shape in which the amount of exposure of the uneven wave changes according to the exposure width (see the broken line part in the figure). When the core member 40 is mounted on the second storage portion 4 of the housing body 2a, the detected portion 81 is mounted so as to be positioned below. The second storage part 4 of the housing body 2a is provided with a detection part 82 at a position facing the detected part 81 when the core member 40 is mounted. Although not shown in detail in detail, the detection unit 82 mechanically or optically detects the exposure amount of the concave and convex waves of the opposed detection target 81 to determine the axial position of the second outer cylinder 43. Thus, the tape width of the printed adhesive tape 150 ″ sandwiched between the first outer cylinder 42 and the second outer cylinder 43 can be automatically detected on the adhesive tape printer 1 side, and further based on this tape width. Thus, the type and basic diameter of the second roll R2 can also be determined.

  A projecting portion 36 having a substantially rectangular tube shape is provided at a position near the lower side of the left bearing portion 39 (a back surface position of the bearing portion 39 as viewed in FIG. 16) (described in detail later).

The first outer cylinder 42 includes a substantially cylindrical first cylindrical portion 45 and a substantially annular first flange portion 46 formed integrally with the right end portion of the first cylindrical portion 45.

  The second outer cylinder 43 is mounted on the outer peripheral side of the other end (specifically, the left end) along the axial direction of the inner cylinder 41 (that is, the left-right direction that is the direction of the axis O3). The second outer cylinder 43 includes a substantially cylindrical second cylindrical portion 47 and a substantially annular second flange portion 48 formed integrally with the left end portion of the second cylindrical portion 47. As described above, the second outer cylinder 43 is mounted so as to be movable in the axial direction (left-right direction) within a predetermined range on the left end side of the core member 40. The inner cylinder 41, the first outer cylinder 42, and the second outer cylinder 43 constitute the drum section 50 (first winding shaft).

  In a state in which the first outer cylinder 42 and the second outer cylinder 43 are attached to the inner cylinder 41, the first flange portion 46 and the second flange portion 48 are disposed so as to face each other in the axial direction. A space capable of receiving the printed adhesive tape 150 ″ is formed between the flange portion 46 and the second flange portion 48.

  Further, in a state where the first outer cylinder 42 and the second outer cylinder 43 are attached to the inner cylinder 41, the first cylindrical portion 45 and the second cylindrical portion 47 have the first flange portion 46 and the second flange portion 48. It extends substantially along the axis O2 so as to be connected, and the outer peripheral side of the first cylindrical portion 45 and the second cylindrical portion 47 (in other words, the space between the first flange portion 46 and the second flange portion 48). A substantially cylindrical paper core 44 (winding cylinder) can be mounted. The paper core 44 is placed on the outer peripheral side of the printed adhesive tape 150 ″ in which the release material layer 151 has been peeled off from the printed adhesive tape 150 ′ in the aforementioned peeling portion 17 so that the tape width direction is the left-right direction. 18 shows a state in which the paper core 44 is not mounted on the outer peripheral side of the first cylindrical portion 45 and the second cylindrical portion 47 (the same applies to FIG. 16). ).

  The shaft member 51 is a substantially cylindrical member as a whole, and includes a first engagement portion 51a that can be attached to the bearing portion 39 installed in the housing body 2a at the right end, and is axially centered. The portion includes a shank portion 51b having a diameter smaller than that of the first engaging portion 51a, and a shaft connecting portion 51c at the left end. A through hole 41 a is provided at the axial center of the inner cylinder 41, and the inner cylinder 41 is rotatably supported by the shaft member 51 by the shank portion 51 b of the shaft member 51 passing through the through hole 41 a.

  The driven gear 52 is a gear that can mesh with the driving gear 38 provided in the second storage portion 4 of the housing body 2a, and an insertion cylinder 52a having a key on the outer peripheral surface at the center of the right end surface thereof. Is provided. By inserting the insertion cylinder 52a into the left end opening of the through hole 41a of the inner cylinder 41, the driven gear 52 and the inner cylinder 41 (and the first outer cylinder 42 and the second outer cylinder 43) can rotate together. A through hole 52b is also formed at the axial center of the entire driven gear 52 including the insertion cylinder 52a, and the left end portion of the shaft member 51 can penetrate the connected inner cylinder 41 and the driven gear 52.

  The lock member 53 includes a substantially cup-shaped cover portion 53a that can accommodate the entire driven gear 52 therein, an operation portion 53b provided at a predetermined circumferential position on the outer periphery of the cover portion 53a, and a left side of the cover portion 53a. A second engagement portion 53c provided at the axial center position on the end surface and a claw portion 53d provided in the vicinity of the second engagement portion 53c are provided. Further, the axial center position of the inner side surface of the lock member 53 (the right end surface of the cover portion 53a) can be detachably connected to the shaft connecting portion 51c at the left end portion of the shaft member 51. Further, the second engaging portion 53 c of the lock member 53 can be mounted on the bearing portion 39 installed on the housing body 2 a in the same manner as the first engaging portion 51 a of the shaft member 51. Further, an exposure hole 53e that exposes a part of the tooth surface of the driven gear 52 is provided at a predetermined position in the circumferential direction of the cover portion 53a. An exposure hole 53f, which will be described in detail later, is provided in the vicinity of the claw portion 53d. The second engagement portion 53c and the exposure hole 53f will be described later in detail (see FIG. 19 described later).

  Here, an example of the assembly procedure of the core member 40 will be described. That is, when the core member 40 is assembled, first, the second cylindrical portion 47 of the second outer cylinder 43 is extrapolated to the outer peripheral side of the left end portion of the inner cylinder 41. At this time, the paper core 44 is not yet attached to the outer peripheral side of the second cylindrical portion 47, and the second outer cylinder 43 including the second flange portion 48 is movable in the left-right direction as described above. Yes. Then, the left end portion of the paper core 44 is lightly fitted to the outer peripheral side of the second cylindrical portion 47 while the left end portion of the paper core 44 is in contact with the right end surface 48 a of the second flange portion 48 in the second outer cylinder 43. At this time, the axial position of the paper core 44 can be positioned by moving the second outer cylinder 43 in the left-right direction in accordance with the widthwise dimension of the paper core 44. When the paper core 44 is completely attached to the outer peripheral side of the second cylindrical portion 47, the second outer cylinder 43 including the second flange portion 48 is fixed to the outer peripheral side of the inner cylinder 41. It becomes impossible to move in the left-right direction. And the 1st outer cylinder 42 containing the 1st flange part 46 is attached to the outer peripheral part of the right end part of the inner cylinder 41 in which the paper core 44 exists in an outer peripheral side so that attachment or detachment is possible. At this time, the right end portion of the paper core 44 is positioned by the first flange portion 46 so that the right end portion thereof contacts the left end surface 46a of the first flange portion 46 of the first outer cylinder 42. .

  Further, the driven gear 52 is attached to the left end portion of the inner cylinder 41, and the driven gear 52 is covered with the lock member 53. Then, the shaft coupling portion 51 c and the shank portion 51 b of the shaft member 51 are passed through the through hole at the center of the shaft of the inner cylinder 41 and the driven gear 52 that are integrally coupled, and the tip of the shaft coupling portion 51 c is formed on the inner surface of the lock member 53 Removably connect. Thus, the core member 40 is assembled (see FIGS. 18A and 18B). In this assembled state, the inner cylinder 41, the first outer cylinder 42, the second outer cylinder 43, the paper core 44, and the driven gear 52 are integrally connected, while the shaft member 51 and the lock member 53 are integrated. Link. The torque transmitted to the driven gear 52 is transmitted to the inner cylinder 41, the first outer cylinder 42, the second outer cylinder 43, and the paper core 44, and rotates with respect to the shaft member 51 and the lock member 53.

  The entire core member 40 is mounted in a state where the first engaging portion 51a of the shaft member 51 and the second engaging portion 53c of the lock member 53 are mounted so as to be supported by the two bearing portions 39, respectively. When stored in the second storage unit 4, the driven gear 52 meshes with the drive gear 38, and the printed adhesive tape 150 ″ is wound up. That is, the printed adhesive tape on the outer peripheral side of the paper core 44. The entire core member 40 is rotated around the axis O2 while 150 ″ is wound sequentially. As a result, the printed adhesive tape 150 ″ is sequentially wound and laminated on the outer peripheral side of the paper core 44 to form the second roll R2. At this time, smoothing when starting the winding operation as described above is performed. For the purpose of illustration, a leader tape 80 is provided on the paper core 44 (see FIG. 17), and a generally serrated tip 80a of the leader tape 80 extends outward from the paper core 44. An adhesive layer 152 provided on the printed adhesive tape 150 ″ is attached to and connected to the tip 80a. As a result, the entire core member 40 including the paper core 44 rotates around the axis O2, so that the printed adhesive tape 150 ″ connected to the leading end 80a of the leader tape 80 is pulled toward the paper core 44 side. Rarely, the second roll R <b> 2 is formed by sequentially winding and laminating the outer periphery of the paper core 44.

  The core member 40 can be repeatedly disassembled and assembled in units of all members including the paper core 44. As a result, the printed adhesive tape 150 ″ is sequentially introduced into the space between the first flange portion 46 and the second flange portion 48 as the core member 40 rotates, and the first cylindrical portion 45 and the second cylindrical portion 47. After the printed adhesive tape 150 ″ is laminated on the paper core 44 attached to the second roll R2, the entire core member 40 can be disassembled and only the second roll R2 can be removed.

  When the core member 40 is mounted on the second storage portion 4 of the housing body 2a, power is reliably supplied to the drum portion 50 (the inner cylinder 41, the first outer cylinder 42, and the second outer cylinder 43). While transmitting, it is desired that the operability is high and the structure thereof is simple. Therefore, in the present embodiment, the following mounting configuration is provided.

  FIG. 19 schematically shows a process of mounting the core member 40 of the present embodiment on the second storage portion 4 of the housing body 2a. FIG. 19A shows a state before the core member 40 is stored, FIG. 19B shows a state immediately after the core member 40 is stored, and FIG. 19C shows a state where the core member 40 is locked. In each figure, only the bearing 39 on the housing body 2a side, the drive gear 38, and the core member 40 are shown.

  First, in FIG. 19A, the bearing portion 39 provided in the housing body 2a (not shown in the drawing) has two so-called D-cut portions 39a. The D cut portion 39a is a portion in which a part (arc portion) of the outer peripheral portion is cut out so as to form a chord in the axial cross section of the substantially cylindrical bearing portion 39. Although not particularly illustrated, when the shaft member 51 is viewed from the side, the D cut portion 39a has a flat surface at a position corresponding to a string. In the example of the present embodiment, in one bearing portion 39, two D-cut portions 39a are arranged so as to be point-symmetrically opposed with respect to the center line. Thereby, in the bearing part 39, the separation distance between the two D cut parts 39a becomes the minimum diameter Ds, and the diameter between the remaining two arc parts becomes the maximum diameter Db.

  Further, the second engagement portion 53c provided at the axial center position of the lock member 53 includes a round hole portion 71 having a diameter substantially equal to the maximum diameter Db of the bearing portion 39, and the round hole portion 71. A slot portion 72 having a width substantially equal to the minimum diameter Ds of the bearing portion 39 is provided. With such a configuration, when the core member 40 is mounted on the housing body 2a, the bearing portion 39 enters the round hole portion 71 while being fitted in the groove portion 72 of the second engagement portion 53c (see FIG. 19 (b)). When the lock member 53 rotates (swings) around the axis by the operation of the lock member 53 via the operation portion 53b, the bearing portion 39 is fitted in the round hole portion 71 of the second engagement portion 53c. It relatively rotates in the round hole 71 (see FIG. 19C). As a result, the bearing 39 cannot be re-fitted into the slot 72 and cannot move outside the round hole 71. In this way, the second engagement portion 53c of the lock member 53 and the bearing portion 39 are fixed by engagement.

  Although not particularly shown, the first engaging portion 51a provided at the right end portion of the shaft member 51 and the bearing portion 39 corresponding to the first engaging portion 51a are also provided with the same mounting configuration as described above. As described above, since the bearing portion 39 and the lock member 53 are integrally connected via the shaft connecting portion 51 c, the swing operation in the lock member 53 is directly interlocked with the first engaging portion 51 a of the shaft member 51. To do. In addition, in order to attach the 1st engaging part 51a and the 2nd engaging part 53c to the corresponding bearing part 39 simultaneously, it is necessary to make the circumferential direction position of each slot part 72 correspond. Further, the exposure hole 53e of the lock member 53 has an arc length corresponding to the swinging width of the operation portion 53b in order to avoid the interference of the cover portion 53a with the engagement point of the drive gear 38 and the driven gear 52. 52 is formed to expose the tooth surface.

  Then, as shown in FIG. 19C, the driven gear 52 is positioned by fixing the shaft member 51 to the bearing portion 39 by the lock member 53, so that the drive gear 38 and the driven gear 52 are meshed with each other. It is possible to prevent tooth skipping at points (connecting portions). Thereby, the power of the drive gear 38 can be reliably transmitted to the drum unit 50.

  Furthermore, in the present embodiment, the housing body 2a is provided with a protrusion 36 and the lock member 53 is provided with a claw portion 53d so that the core member 40 can be more securely fixed to the second storage portion 4 of the housing body 2a. Yes.

  FIG. 20 specifically shows the appearance of the process of locking the projection 36 of the housing body with the claw 53d of the lock member 53. FIG. 20 (a) is shown in FIG. (B) corresponds to FIG. 19 (c), respectively. In each figure, the protrusion 36 fixedly provided on the housing body 2a side is indicated by a broken line.

  As described above, the projecting portion 36 is provided near the lower portion of the bearing portion 39. The claw portion 53d is formed integrally with the lock member 53, and is provided at a position where it does not interfere with the protrusion 36 when the core member 40 is attached to the housing body 2a (see FIG. 20A). . When the lock member 53 rotates (swings) about the axis by the operation of the lock member 53 via the operation portion 53b, the claw portion 53d is locked to the lower surface of the projection 36 (see FIG. 20B). ). The shaft member 51 can be more firmly fixed to the bearing portion 39 by the locking of the claw portion 53d.

  Further, as described above, the protrusion 36 is formed in a hollow shape, and its opening is directed to the core member 40 side. Although not particularly illustrated, an optical sensor in which a light emitting portion and a light receiving portion are adjacently combined is provided inside the housing body 2a (see FIG. 21 described later), and projection light from the light emitting portion is projected onto the core member 40. The reflected light is received by the light receiving unit. The hollow hole inside the protrusion 36 becomes a passage hole for the projection light and the reflected light. Correspondingly, the exposure hole 53f of the lock member 53 shields the projection light without overlapping the opening of the protrusion 36 at the position before the lock member 53 is locked (see FIG. 20A). In the post-lock position, the projection light passes through the opening of the protrusion 36. Thereby, the presence or absence of the locked state of the core member 40 can be detected by the optical sensor. The projection light that has passed through the exposure hole 53f of the lock member 53 is projected onto the driven gear 52. As shown in FIG. 17, the driven gear 52 is provided with slit holes 52c at equal intervals in the circumferential direction. Thus, a so-called rotary encoder can be configured to detect the rotation state of the second roll R2. Although not specifically shown, the configuration of the rotary encoder is also provided in the third roll R3.

<Control system>
Next, the control system of the adhesive tape printer 1 will be described with reference to FIG. In FIG. 21, the adhesive tape printer 1 includes a CPU 212 that constitutes a calculation unit that performs a predetermined calculation. The CPU 212 is connected to the RAM 213 and the ROM 214. The CPU 212 performs signal processing in accordance with a program stored in advance in the ROM 214 while using the temporary storage function of the RAM 213, thereby controlling the entire adhesive tape printer 1. At this time, the ROM 214 stores a control program for executing a control process to be described later. The CPU 212 controls the motor drive circuit 218 that controls the conveyance motor M1 that drives the conveyance roller 12, and the motor drive circuit that controls the adhesion winding motor M2 that drives the second roll R2. 219, a motor drive circuit 220 that controls the driving of the release paper winding motor M3 that drives the third roll R3, a print head control circuit 221 that controls the energization of the heating elements of the print head 11, and the cutter The motor 30 is connected to a motor drive circuit 222 that controls the drive of the cutter motor M4 that moves the movable blade 32 of the mechanism 30.

  Further, the CPU 212 includes a display unit 215 and an operation unit 216, two optical sensors 223 (first rotation detection unit) and 224 (second rotation detection unit) corresponding to the second roll R2 and the third roll R3, respectively. , PC 217 is connected.

  The ROM 214 stores print data (dot pattern) such as characters and symbols received and printed from the PC 217 in association with the code data. The CPU 212 uses the stored print data to print the print data. Print data for printing in the print area of the label L is generated. The CPU 212 causes the print head 11 to print via the print head control circuit 217 in accordance with the generated print data while feeding the print-receiving adhesive tape 150 by the transport roller 12 to create an adhesive tape.

<Print processing control details>
Next, the control contents of the printing process executed by the CPU 212 of the adhesive tape printer 1 will be described with reference to FIGS. First, in FIG. 22, for example, when the power of the adhesive tape printer 1 is turned on by the operator, this flow is started (“START” position).

  First, in step S5, the CPU 212 performs a process mode selection input by a user mode selection operation via the operation unit 53b.

  Next, in step S10, the CPU 212 determines whether or not the processing mode selected and input in step S5 is the preparation mode. If the preparation mode has been selected, the determination is satisfied (S10: YES), and the routine goes to Step S100.

  In step S100, a preparation mode process for preparing before performing a normal printing process is executed. Then, this flow ends.

  On the other hand, if the preparation mode is not selected in the determination in step S10, the determination is not satisfied (S10: NO), and the process proceeds to step S15.

  In step S15, the CPU 212 determines whether or not the processing mode selected and input in step S5 is the normal mode. If the normal mode has been selected, the determination is satisfied (S15: YES), and the routine goes to Step S200.

  In step S200, normal mode processing for performing normal printing processing is executed. Then, this flow ends.

  On the other hand, if the normal mode is not selected in the determination in step S15, the determination is not satisfied (S15: NO), and the process proceeds to step S300.

  In step S300, a cutting mode process for cutting the printed adhesive tape 150 ″ after performing the normal printing process is executed. Then, this flow is ended.

  Hereinafter, the preparation mode, the normal mode, and the cutting mode will be described.

<1: Preparation mode>
FIG. 23 schematically shows a printing preparation process in the preparation mode. First, the user feeds the print-receiving adhesive tape 150 from the first roll R1, and passes the fed print-receiving adhesive tape 150 between the transport roller and the print head 11 (see FIG. 23A). During this time, the CPU 212 controls the transport motor M1 so as to rotate the transport roller in the transport direction for a predetermined time.

  Then, the release material layer is peeled off from the print-receiving pressure-sensitive adhesive tape 150, and the tip of the printed pressure-sensitive adhesive tape 150 'composed of the base material layer and the pressure-sensitive adhesive layer is fixed to the core of the second roll R2. On the other hand, the tip of the release material layer peeled off from the printing adhesive tape 150 is fixed to the third roll R3 (see FIG. 23B).

  In this state, the CPU 212 controls the conveying motor M1 and the adhesive winding motor M2 so as to stop the conveying roller for a predetermined time and rotate only the second roll R2 in the winding direction (FIG. 23). (See (b)). As a result, the printed adhesive tape 150 ′ from which the release material layer has been peeled off is pulled by the stopped conveying roller and the second roll R <b> 2 rotating in the winding direction, and when the slack is removed, the second roll R <b> 2 is removed. The rotation stops and the tension is applied. When the rotation of the second roll R2 is detected at the time when the tension should be applied to the printed adhesive tape 150 ′ in this way, the tip of the printed adhesive tape 150 ′ with respect to the paper core 44 is detected. Since the fixing is poor, it is considered that the second roll R2 is idle, and the trouble is notified.

  Next, the CPU 212 controls the conveyance motor M1 and the release paper winding motor M3 so that the conveyance roller is stopped for a predetermined time and only the third roll R3 is rotated in the winding direction (FIG. 23 ( c)). As a result, the release material layer peeled off from the printed adhesive tape 150 'is pulled by the stopped conveying roller and the third roller R3 rotating in the winding direction, and when the slack is removed, the third roller R3 is removed. The rotation stops and the tension is applied. At this time, even when the peeled point between the printed adhesive tape 150 ′ and the release material layer moves due to the drawing of the printed adhesive tape 150 ′ by the rotation of only the second roller R2, the original position (drawing) It is possible to return to the position of the peeled portion 17 (see the broken line portion in FIGS. 23B and 23C). If the rotation of the second roll R2 is detected at the time when the tension should be applied to the release material layer in this way, the fixing of the tip of the release material layer to the third roll R3 is poor. It is assumed that the third roll R3 is idle, and a failure is reported.

  Next, the CPU 212 performs the transporting motor M1, the adhesive winding motor M2, and the peeling so as to rotate all of the transporting roller, the second roller R2, and the third roll R3 without performing a printing operation for a predetermined time. The paper winding motor M3 is controlled (not particularly shown). By performing this preliminary operation, it is possible to confirm in advance whether a series of operations including feeding, transporting, winding, and winding of the release material layer of the adhesive tape 150 to be printed is normally performed.

The predetermined time to wait in this case may be a time that allows the appropriate tension to be applied by removing the slack of the release material layer between the transport roller 12 and the third roll R3, including pulling back of the release point. When the predetermined time has elapsed, the process proceeds to step S155.

  In step S155, the CPU 212 determines whether or not the third roll R3 is rotating at this time based on the detection content of the optical sensor 224 corresponding to the third roll R3.

  In step S165, the CPU 212 starts driving the conveyance motor M1, the adhesive winding motor M2, and the release paper winding motor M3.

  In step S170, the CPU 212 stands by in a loop until a predetermined time has elapsed from the start of driving of each motor in step S145. The predetermined time to wait in this case is a time that can sufficiently visually confirm whether or not a series of operations including feeding, transporting, winding, and winding of the release material layer is normally performed. It's okay. When the predetermined time has elapsed, the process proceeds to step S175.

  In step S175, the CPU 212 stops driving the conveyance motor M1, the adhesive winding motor M2, and the release paper winding motor M3.

  Next, in step S180, the CPU 212 notifies the display unit that, for example, all the preparation operations have been normally performed and the preparation mode processing has been completed. Then, this flow ends.

  On the other hand, in the determination of step S135, if the second roll R2 is rotating, the determination is satisfied (S135: YES), and the process proceeds to step S185.

  In step S185, the CPU 212 stops driving the adhesive winding motor M2.

<2: Normal mode>
FIG. 25 schematically shows the process in the normal mode. First, the CPU 212 starts driving the conveyance motor M1, the adhesive winding motor M2, and the release paper winding motor M3 together with the printing operation by the print head 11. During the subsequent normal printing operation, the CPU 212 determines that there is an abnormality when no rotation is detected by at least one of the two optical sensors 223 and 224 corresponding to the second roll R2 and the third roll R3, respectively. judge. In the normal mode, it is normal that the rotation of both the second roll R2 and the third roll R3 is detected by the two optical sensors 223 and 224, and there is no rotation by at least one of the optical sensors 223 and 224. If this is detected, it is assumed that a malfunction has occurred due to a tape jam (jam) or the like, and the malfunction is reported.

  The control content of the normal mode process S200 executed by the CPU 212 of the adhesive tape printer 1 in order to realize the control content will be described with reference to FIG.

  First, in step S205, the CPU 212 starts driving the conveyance motor M1, the adhesive winding motor M2, and the release paper winding motor M3.

  Next, in step S210, the CPU 212 starts printing by the print head 11.

  Next, in step S215, the CPU 212 determines whether the rotation of the second roll R2 has stopped based on the detection content of the optical sensor corresponding to the second roll R2. If the rotation of the second roll R2 is not stopped, the determination is not satisfied (S215: NO), and the process proceeds to step S220.

  In step S220, the CPU 212 determines whether the rotation of the third roll R3 has stopped based on the detection content of the optical sensor corresponding to the third roll R3. If the rotation of the third roll R3 is not stopped, the determination is not satisfied (S220: NO), and the process proceeds to step S225.

  In step S225, the CPU 212 determines whether printing has been completed with the planned length. If printing has not ended, the determination is not satisfied (S225: NO), and the process returns to step S215 to repeat the same procedure.

  On the other hand, when the printing is finished, the determination is satisfied (S225: YES), and the routine goes to Step S230.

  In step S230, the CPU 212 stops printing by the print head 11.

  Next, in step S235, the CPU 212 stops driving the transport motor M1, the adhesive winding motor M2, and the release paper winding motor M3.

  Next, in step S240, the CPU 212 notifies the display section that, for example, all the printing operations have been normally performed and the normal mode process has been completed. Then, this flow ends.

  On the other hand, when the rotation of the second roll R2 is stopped in the determination in step S215, the determination is satisfied (S215: YES), and the process proceeds to step S245.

  In step S245, the CPU 212 stops driving the conveyance motor M1, the adhesive winding motor M2, and the release paper winding motor M3.

  In step S250, the CPU 212 determines that the rotation has stopped because the printed adhesive tape 150 'of the second roll R2 is in a jammed state, and notifies the display 212 by displaying that fact. Then, this flow ends.

  On the other hand, when the rotation of the third roll R3 is stopped in the determination in step S220, the determination is satisfied (S220: YES), and the process proceeds to step S225.

  In step S225, the CPU 212 stops driving the conveyance motor M1, the adhesive winding motor M2, and the release paper winding motor M3.

  Next, in step S210, the CPU 212 considers that the rotation has stopped because the release material layer of the third roll R3 is in a jammed state, and notifies this by displaying the fact on the display unit. Then, this flow ends.

<3: Cutting mode>
FIG. 27 schematically shows a tape cutting process in the cutting mode. When the printing is finished through the normal mode, the transport roller, the second roll R2, and the third roll R3 all stop rotating. At this time, since the outer diameter of the second roll R2 is increased, the pressing roller 37 comes into contact with the outer periphery of the second roll R2 to be biased (see FIG. 27A).

  Then, the conveyance motor M1 and the adhesive winding motor M2 are controlled so that the conveyance roller is stopped and the second roll R2 is rotated in the winding direction. As a result, the cut portion of the printed adhesive tape 150 ′ is in a state in which tension is applied by the transport roller 12 stopped on the upstream side and the second roll R 2 that attempts to rotate in the winding direction on the downstream side. (See FIG. 27B).

  At the same time, the release paper winding motor M3 is controlled so that the third roll R3 is also rotated in the winding direction. Since the third roll R3 also tries to rotate in addition to the second roll R2, it is possible to apply a stronger tension to the printed adhesive tape 150 '. Further, at this time, when the printed adhesive tape 150 'is pulled by the rotation of the second roller R2, the peeling point (peeling position) between the printed adhesive tape 150' and the release material layer is moved to the downstream side. However, it can be pulled back to the original position (the tip position of the peeling portion 17) (see the broken line portion in FIG. 27B).

  In this state, the printed adhesive tape 150 ′ is cut between the transport roller 12 and the second roll R <b> 2 by the cutter mechanism 30. Thereby, it is possible to prevent the printed adhesive tape 150 'from loosening when the cutter mechanism 30 contacts the edge of the printed adhesive tape 150', and to prevent the occurrence of defective cutting (see FIG. 27B).

  Then, the conveyance roller 12 is stopped and the second roll R2 is controlled to rotate in the winding direction. After that, the second roll R2 is rotated for a predetermined time in the winding direction, and then stopped for adhesive winding. The motor M2 is controlled (see FIG. 27 (c)). In other words, after the printed adhesive tape 150 ′ is completely cut by the cutter mechanism 30, the second roll R2 is not stopped immediately, but is rotated after a predetermined time and then stopped. As a result, the second roll R2 can be rotated by a predetermined amount after completion of the cutting, so that the end portion of the printed adhesive tape 150 ′ generated by the cutting can be surely wound by the second roll R2. At this time, since the pressing roller 37 is biased to the outer periphery of the second roll R2, the end portion of the printed adhesive tape 150 'is reliably wound on the second roll R2.

  In addition, when the rotation of the second roll R2 is not detected at the time when the end portion of the printed adhesive tape 150 ′ should be wound around the second roll R2, the cutting by the cutter mechanism 30 is performed. Is inferior, and the second roll R2 is regarded as not rotating, and a malfunction is reported.

  The control content of the cutting mode processing S300 executed by the CPU 212 of the adhesive tape printer 1 to realize the above control content will be described with reference to FIG.

  First, in step S305, the CPU 212 starts driving the adhesive take-up motor M2 and the release paper take-up motor M3.

  In step S310, the CPU 212 stands by in a loop until a predetermined time has elapsed from the start of driving of each motor in step S305. The predetermined time to wait in this case may be a time that can remove the slack of the printed adhesive tape 150 ′ from the conveyance roller 12 to the second roll R <b> 2 and can apply an appropriate tension. Alternatively, it may be a period of time in which an appropriate tension can be applied by removing the slack of the release material layer between the transport roller 12 and the third roll R3, including pulling back of the release point described above. When the predetermined time has elapsed, the process proceeds to step S315.

  In step S315, the CPU 212 drives the cutter motor to cut the printed adhesive tape 150 ′ by the operation of the cutter mechanism 30.

  Next, in step S320, the CPU 212 determines whether or not the second roll R2 has rotated based on the detection content of the optical sensor corresponding to the second roll R2. If the second roll R2 is rotating, the determination is satisfied (S320: YES), and the routine goes to Step S325.

  In step S325, the CPU 212 stands by in a loop until a predetermined time has elapsed from the cutting operation of the cutter mechanism 30 in step S315. The predetermined time to wait in this case may be a time that allows the appropriate tension to be applied by removing the slack of the release material layer between the transport roller 12 and the third roll R3, including pulling back of the release point. When the predetermined time has elapsed, the process proceeds to step S330.

  In step S330, the CPU 212 stops driving the release paper winding motor M3.

  Next, in step S335, the CPU 212 stands by in a loop until a predetermined time has elapsed from the cutting operation of the cutter mechanism 30 in step S315. The predetermined time for waiting in this case may be a time that can surely wind up the end portion of the printed adhesive tape 150 ′ generated by cutting with the second roll R <b> 2. When the predetermined time has elapsed, the process proceeds to step S340.

  In step S340, the CPU 212 stops driving the adhesive take-up motor M2.

  Next, in step S345, the CPU 212 notifies that the cutting operation has been normally performed and the cutting mode process has ended by displaying it on the display unit. Then, this flow ends.

  On the other hand, in the determination of step S320, if the second roll R2 is not rotating (stopped), the determination is not satisfied (S320: NO), and the process proceeds to step S350.

  In step S350, the CPU 212 stops driving the adhesive take-up motor M2 and the release paper take-up motor M3.

  Next, in step S355, the CPU 212 notifies that the second roll R2 does not rotate because the cutting by the cutter mechanism 30 is defective and displays that fact on the display unit. Then, this flow ends.

  In the above, the center axis of the third roll R3 corresponds to the second winding shaft described in each claim, and the procedures of step S105, step S125, step S205, and step S165 function as the drive control means described in each claim. Then, the procedure of step S135, step PS155, step S215, and step S220 functions as an abnormality determination unit described in each claim, and the procedure of step S5 functions as a mode setting unit described in each claim.

<Effects of this embodiment>
As described above, in the present embodiment, the printing adhesive tape 150 is fed from the first roll R <b> 1 by the conveyance roller 12 and is applied to the base material layer 153 of the printing adhesive tape 150 conveyed by the print head 11. Desired printing is performed to form a printed adhesive tape 150 '. Thereafter, the release material layer 151 is peeled off from the printed adhesive tape 150 ′, and the printed adhesive tape 150 ′ composed of the base material layer 153 and the adhesive layer 152 is sequentially wound by the drum unit 50 to form the second roll R <b> 2. Become. On the other hand, the release material layer 151 peeled off from the printed adhesive tape 150 'is sequentially wound around the central axis of the third roll R3 to become the third roll R3.

  In the pressure-sensitive adhesive tape printer 1 of the present invention, printing preparation is performed as follows. First, the user feeds out the printing adhesive tape 150 from the first roll R1. Next, the fed printing adhesive tape 150 is passed between the transport roller 12 and the print head 11 to peel off the release material layer 151, and the tip of the adhesive tape composed of the base material layer 153 and the adhesive layer 152 is placed on the drum unit 50. Secure to. On the other hand, the tip of the release material layer 151 peeled off from the adhesive tape is fixed to the central axis of the third roll R3.

  In this state, the conveyance motor M1, the adhesive take-up take-up are performed so that the carry roller 12 is stopped and the central axis of the drum unit 50 and the third roll R3 is rotated in the take-up direction in the procedure of Step S105 and Step S125. The motor M2 and the release paper winding motor M3 are controlled. As a result, the adhesive tape from which the release material layer 151 has been peeled off is pulled by the transport roller 12 that has stopped and the drum unit 50 that rotates in the winding direction, and when the slack is removed, the rotation of the drum unit 50 stops. Thus, the tension is applied. Similarly, the release material layer 151 peeled off from the adhesive tape is pulled by the stopped conveying roller 12 and the central axis of the third roll R3 rotating in the winding direction, and when the slack is removed, the third roll The rotation of the central axis of R3 stops and the tension is applied.

  In the present invention, the slack of the printed adhesive tape 150 ′ taken up by the drum unit 50 and the release material layer 151 taken up by the central axis of the third roll R 3 is removed by such control in preparation for printing. The tension can be applied.

  Further, in the present embodiment, in particular, in the state where the tip of the printed adhesive tape 150 ′ is fixed to the drum portion 50 and the tip of the release material layer 151 is fixed to the central axis of the third roll R3, steps S105 and S125 are performed. In the procedure, the transport roller 12 is stopped, and the transport motor M1, the adhesive winding motor M2, and the release paper winding motor M3 are rotated so that the central axis of the drum unit 50 and the third roll R3 is rotated in the winding direction. To control. Thereby, when the slack of the tape is removed normally, the optical sensor 223 detects that the drum unit 50 or the second roll R2 has stopped after rotating for a predetermined time, and the optical sensor 224 detects the third roll. It is detected that the central axis of R3 or the third roll R3 has stopped after rotating for a predetermined time.

  In the present invention, in the procedure of step S135 and step S155, at least one of the optical sensor 223 and the optical sensor 224 causes the drum unit 50 (or the second roll R2; the same applies hereinafter) or the central axis ( Or it determines with it being abnormal when it is detected that rotation of 3rd roll R3. If the rotation of the central axis of the drum unit 50 or the third roll R3 does not stop after a predetermined time according to the control in the steps S105 and S125, the printed adhesive tape 150 ′ is fixed to the drum unit 50. The center axis of the drum unit 50 or the third roll R3 is idle due to the defect or the fixing of the release material layer 151 to the center axis of the third roll R3, or the printed adhesive tape 150 ′ or the release material layer 151 is idle. It is conceivable that the slack is not removed sufficiently. In the present invention, such an abnormality can be detected immediately by the procedures of step S135 and step S155. As a result, the user can re-fix the tape to the take-up shaft or rotate the roll to remove the slack, which causes a malfunction in the adhesive tape printer 1 in the subsequent printing operation. Can be prevented.

  In the present embodiment, in particular, the adhesive winding motor M1 and the release paper winding motor M3 are rotated in the order of the central axis of the drum unit 50 and the third roll R3 in the order of steps S105 and S125. Start control sequentially. As described above, the rotation is not started at the same time with respect to the central axis of the drum unit 50 and the third roll R3, but the rotation is started at different timings, so that the abnormality determination timing according to the steps S135 and S155 is determined. Thus, it is possible to determine whether the abnormality is on the printed adhesive tape 150 ′ side (fixing failure or loosening) or on the release material layer 151 side (fixing failure or loosening), and the location of the abnormality can be specified.

  Further, the printed adhesive tape 150 ′ has a substantially linear path between the transport roller 12 and the drum unit 50, but the release material layer 151 is turned from the peeled portion to the central axis of the third roll R 3. It is a wound structure. For this reason, by rotating the drum unit 50 and the center axis of the third roll R3 in this order, the release material layer 151 is wound in a state where tension is applied to the printed adhesive tape 150 '. It is possible to prevent problems due to the pulling of 150 'or the like.

  In this embodiment, in particular, when the operation mode of the adhesive tape printer 1 is set to the preparation mode for performing the preparation operation before generating the second roll R2 in the procedure of step S5, the drum unit 50 is set. And abnormality determination is performed by rotating the central axis of 3rd roll R3. Thereby, since it is possible to detect abnormalities such as improper fixing to the tape winding axis and slack in the preparation mode, it is possible to reliably prevent the adhesive tape printer 1 from causing an operation failure in the printing operation after the preparation mode. it can.

  In this embodiment, in particular, when the operation mode of the adhesive tape printer 1 is set to the normal mode for generating the second roll R2 in the procedure of step S5, the transport roller is used in the procedure of step S205. The conveyance motor M1, the adhesive take-up motor M2, and the release paper take-up motor M3 are controlled such that the drum 12 and the central axis of the third roll R3 are rotated in the take-up direction. As a result, the pressure-sensitive adhesive tape 150 to be printed is fed from the first roll R <b> 1 by the transport roller 12, and the release material layer 151 is peeled off from the printed pressure-sensitive adhesive tape 150 ′ on which printing has been performed, and the base material layer 153 and the pressure-sensitive adhesive layer 152. The printed adhesive tape 150 ′ is wound by the drum unit 50 to become the second roll R 2, while the release material layer 151 peeled off from the printed adhesive tape 150 ′ is formed by the central axis of the third roll R 3. It is wound up sequentially and becomes the third roll R3.

  At this time, the procedure of step S215 and step S220 is determined to be abnormal when it is detected that there is no rotation by at least one of the optical sensor 223 and the optical sensor 224. In the normal mode, it is normal for the optical sensor 223 and the optical sensor 224 to detect the rotation of both the drum unit 50 and the center axis of the third roll R3, and at least one of the optical sensors does not rotate. Is detected, a malfunction due to a jam or the like is considered. In the present invention, such an abnormality in the normal mode can be immediately detected by the procedures of step S215 and step S220.

  In the present embodiment, in particular, in the preparation mode, when no abnormality is determined by the procedures of step S135 and step S155, in other words, in the preparation mode, both the printed adhesive tape 150 ′ side and the release material layer 151 side are loosened. Is removed normally, in the procedure of step S165, the conveying motor 12 is rotated for a predetermined time and the drum 50 and the central axis of the third roll R3 are rotated in the winding direction for a predetermined time. M1, the adhesive winding motor M2, and the release paper winding motor M3 are controlled. That is, the same operation as the normal mode excluding printing (hereinafter referred to as “preliminary operation”) is performed for a predetermined time. By performing this preliminary operation, it is determined in advance whether or not a series of operations including feeding out, conveying, winding, and winding of the release material layer 151 of the printing adhesive tape 150 from the first roll R1 is normally performed. It becomes possible to confirm. Therefore, it is possible to reliably prevent malfunction of the adhesive tape printer 1 in the subsequent printing operation.

  In the above, the case where the present invention is applied to the adhesive tape printing apparatus 1 that performs printing on the print-receiving adhesive tape 150 has been described as an example. However, the present invention is not limited to this, and processing other than printing is performed on the adhesive tape. It is also possible to apply to the tape processing apparatus to perform.

  In addition to those already described above, the methods according to the above-described embodiments and modifications may be used in appropriate combination.

  In addition, although not illustrated one by one, the present invention is implemented with various modifications within a range not departing from the gist thereof.
