A technique for calculating is known (see, for example, Patent Document 1).

JP 2011-245758 A

  In some cases, there is a need to use a plurality of types of wide and narrow tapes for the width dimension of the tape that is drawn out from the tape roll. Here, in the above prior art, the detected identifier to be optically detected is formed on a circular flange-shaped detected body provided on one side in the axial direction of the tape roll. In such a structure in which the detected identifier is provided on the flange (or roll body) attached to the roll, when the detecting means performs optical detection from one side in the axial direction as described above, from the detecting means to the detected identifier. The distance varies depending on whether the tape width is wide or narrow. As a result, the detection accuracy is not constant, and it may be difficult to accurately calculate the remaining tape amount.

  An object of the present invention is to provide a tape cartridge and a printing apparatus that can calculate the remaining amount of tape with high accuracy regardless of the width of the tape.

  In order to achieve the above object, the present invention relates to a first tape roll in which a tape is wound around an outer periphery of a first winding core, and an axial direction of the first winding core of the first tape roll. A predetermined fixed identifier formed on one side, a flange portion that covers one side of the detected identifier in the axial direction, and a first fixed shaft member that rotatably supports the first core; It has a bracket part which supports a 1st fixed shaft member in the axial direction both sides, and covers the radial direction outer peripheral side of the said to-be-detected identifier.

  The tape cartridge of the present invention is provided with a first tape roll on which the tape is wound around the outer periphery of the first core so that the tape can be fed out. The first core is rotatably supported by a first fixed shaft member supported by the bracket portion. When the first core is used, for example, after being mounted on an appropriate tape processing device such as a printing device, the first core is By rotating around the first fixed shaft member, the tape wound around the outer peripheral side of the first core of the first tape roll is fed out.

  At this time, in the present invention, in order to detect the remaining amount of tape (in other words, consumption), a predetermined detected identifier (a so-called encoder mark) is provided on one side in the axial direction of the first core of the first tape roll. Is formed. That is, as the tape is fed out and consumed from the first tape roll, the diameter of the first tape roll is reduced, and as a result, the roll rotation speed is increased even at the same tape feeding speed. Accordingly, the degree of diameter reduction of the first tape roll as described above, that is, the remaining tape amount of the first tape roll is easily calculated by optically detecting the detected identifier of the first core, for example. be able to.

  Here, in the present invention, the detected identifier to be optically detected is not the first tape roll, for example, the roll body or the flanges provided on both axial sides of the roll, but the first core. Is provided. This has the following significance. That is, there may be a need to use a plurality of types of widths of the tape. In the structure in which the detected identifier is provided on the roll body or the flange as described above, for example, when optical detection is performed by the detecting means from one side in the axial direction of the roll, the distance from the detecting means to the detected identifier is Varies depending on whether the tape width is wide or narrow. As a result, the detection accuracy is not constant, and it may be difficult to ensure high detection accuracy.

  In the present invention, the detected identifier is provided on the first core as described above. As a result, even when wide and narrow types of tapes are used in the first tape roll, the distance from the detecting means to the detected identifier is constant (if the first core is shared by all rolls). It can be. As a result, unlike the above, since the detection accuracy can be made constant, the remaining amount of the tape can be detected stably and with high accuracy. In addition, the bracket portion covers the radially outer peripheral side of the detected identifier, and the flange portion of the first fixed shaft member covers one axial direction side of the detected identifier (for example, detection for optical detection described above). It is possible to prevent the detected identifier from being dusted / stained (provided that the detection is not hindered by providing a hole). Therefore, this also makes it possible to increase the accuracy of the remaining amount detection.

  According to the present invention, the remaining tape amount can be calculated with high accuracy regardless of the width of the tape.

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

<Case>
1 to 4, a tape printing apparatus 1 (corresponding to a tape processing apparatus or printing apparatus) of the present embodiment has a casing 2 (corresponding to an apparatus casing) that constitutes the outer shell of the apparatus. The housing 2 includes a housing body 2 a, a rear side opening / closing part 8, and a front side opening / closing cover 9.

  The housing main body 2a includes a first storage portion 3 provided on the rear side, and a second storage portion 5 and a third storage portion 4 provided on the front side.

  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 and the second opening / closing cover 8b correspond to the opening / closing covers described in the claims.

  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 and 2) covering the front upper side of the first storage unit 3. It can be rotated between the open position (the state shown in FIGS. 3 and 4).

  A head holder 10 is provided inside the first opening / closing cover 8a (see also FIG. 3). The first opening / closing cover 8a rotates about the rotation axis K1 so that the print head 11 provided in the head holding body 10 is moved with respect to the conveyance roller 12 provided in the housing body 2a. Can be separated and approached relatively. Specifically, the first opening / closing cover 8a is opened from the closed position (the state shown in FIGS. 1 and 2) in which the print head 11 is close to the conveying roller 12 and from the closed position (see FIG. 1). 3 and the state of FIG. 4).

  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 (the state shown in FIGS. 3 and 4).

  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 side opening / closing cover 9 is connected to the upper part of the front side of the housing body 2a so as to be openable and closable. The front opening / closing cover 9 can open and close above the third storage portion 4 by rotating around a predetermined rotation axis K3 provided at the upper end of 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 and 2) covering the upper side of the third storage unit 4 to expose the upper side of the third storage unit 4 (FIGS. 3 and 5). 4 state).

<Printed tape roll and its surroundings>
At this time, as shown in FIGS. 2 to 4, the tape cartridge TK (see FIG. 2) is attached to and detached from the first predetermined position 13 below the front opening / closing cover 9 in the closed state in the housing body 2a. Installed as possible. The tape cartridge TK includes a print-receiving tape roll R1 (corresponding to a first tape roll) wound around an axis O1 (corresponding to a first axis).

  That is, the tape cartridge TK includes a print-receiving tape roll R1 and a connecting arm 16, as shown in FIG. 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.

  The first bracket portions 20 and 20 sandwich the print-receiving tape roll R1 from both the left and right sides along the axis O1 through a pair of left and right substantially circular roll flange portions f1 and f2, and a tape cartridge. In a state in which the TK is mounted on the housing body 2a, the print-receiving tape roll R1 is held so as to be rotatable around the axis O1 (detailed structure of holding will be described later). The first bracket portions 20 are connected to each other while avoiding interference with the outer diameter of the print-receiving tape roll R1 by a first connection portion 22 extending substantially along the left-right direction at the upper end portion.

  The print-receiving tape roll R1 is rotatable when the tape cartridge TK is mounted inside the housing body 2a. The print-receiving tape roll R1 includes a print-receiving tape 150 (including a print-receiving layer 154, a base material layer 153, a pressure-sensitive adhesive layer 152, and a release material layer 151, which will be described later) consumed by feeding. It is wound around the axis O1 in the left-right direction in advance.

  By mounting the tape cartridge TK, the print receiving tape roll R1 is received from above and is stored in the first storage portion 3 in a state where the winding axis O1 of the print receiving tape 150 is in the left-right direction. The print-receiving tape roll R1 is in a predetermined rotation direction (A direction in FIG. 2) in the first storage unit 3 in a state where the print-receiving tape roll R1 is stored in the first storage unit 3 (a state where the tape cartridge TK is mounted). The tape to be printed 150 is fed out.

  In this embodiment, the case where the to-be-printed tape 150 provided with adhesiveness is used is illustrated. That is, the print-receiving tape 150 includes a print-receiving layer 154, a base material layer 153, an adhesive layer 152, and a release material layer 151 from one side in the thickness direction (upper side in FIG. 2) to the other side (in FIG. 2). The lower layers are stacked in this order. The print target layer 154 is a layer in which a desired print portion 155 (see a partially enlarged view in FIG. 2) is formed by thermal transfer of ink by the print head 11. 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.

<Conveyance roller and print head>
2 to 4, the conveyance roller 12 (corresponding to a conveyance unit) is provided on the middle upper side of the first storage unit 3 and the second storage unit 5 in the housing body 2 a. The transport roller 12 is stored in the first storage unit 3 by being driven through a gear mechanism (not shown) by a transport motor M1 (corresponding to a driving unit) provided inside the housing body 2a. The print-receiving tape 150 fed out from the print-receiving tape roll R1 is conveyed in a tape posture in which the tape width direction is the left-right direction.

  In addition, the print head 11 is provided in the head holding portion 10 provided in the first opening / closing cover 8a. 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 includes a transport roller in the first opening / closing cover 8a in the closed state of the head holding unit 10 so as to sandwich the print-receiving tape 150 transported by the transport roller 12 in cooperation with the transport roller 12. 12 is disposed at a position facing above 12. 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 print target layer 154 of the print target tape 150 sandwiched between the conveyance rollers 12 by using an ink ribbon IB of an ink ribbon cartridge RK described later. Thus, the printed tape 150 ′ is obtained.

<Ink ribbon cartridge>
As shown in FIGS. 2 and 3, the ink is placed at a second predetermined position 14 (corresponding to a predetermined portion) below the first opening / closing cover 8a in the closed state of the housing body 2a and above the tape cartridge TK. A ribbon cartridge RK is detachably mounted. The detailed structure of the ink ribbon cartridge RK is shown in FIG.

  As shown in FIG. 6, the ink ribbon cartridge RK includes a cartridge housing 80, a ribbon feeding roll R <b> 4 on which an unused ink ribbon IB is wound so as to be fed out, and a ribbon take-up roll R <b> 5. The cartridge housing 80 includes a rear-side feeding roll storage portion 81, a front-side take-up roll storage portion 82, and a connecting portion 83 that connects both the storage portions 81 and 82. The connecting portion 83 connects the take-up roll storage portion 82 and the supply roll storage portion 81 while exposing the ink ribbon IB fed from the ribbon feed roll R4 to the outside of the cartridge casing 80.

  The feeding roll storage unit 81 is configured by combining a substantially semi-cylindrical upper part 81a (one side part) and a lower part 81b. The ribbon feeding roll R4 is rotatably supported in the feeding roll storage unit 81, and rotates in a predetermined rotation direction (D direction in FIG. 2) when the ink ribbon cartridge RK is mounted. The ink ribbon IB for performing print formation by the head 11 is fed out.

  The take-up roll storage unit 82 is configured by combining a substantially semi-cylindrical upper part 82a and a lower part 82b. The ribbon take-up roll R5 is rotatably supported in the take-up roll storage unit 82, and rotates in a predetermined rotation direction (E direction in FIG. 2) with the ink ribbon cartridge RK mounted. Then, the used ink ribbon IB after the printing is formed is wound up.

  That is, in FIG. 2, the ink ribbon IB fed out from the ribbon feeding roll R4 is further arranged on the print head 11 side of the print-receiving tape 150 in a state of being sandwiched between the print head 11 and the conveying roller 12, and the print head. 11 below. Then, after the ink from the ink ribbon IB is transferred to the print layer 154 of the print-receiving 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 roll R5. Rolled up.

  <Release material roll and its periphery>

  As shown in FIG. 5, the connecting arm 16 of the tape cartridge TK includes a peeling portion 17 including, for example, a substantially horizontal slit shape. The peeling portion 17 is a portion where the release material layer 151 is peeled off from the printed tape 150 ′ that is fed out from the print-receiving tape roll R 1 and conveyed forward. As shown in FIG. 2, the printed tape 150 ′ on which the printing has been formed as described above is peeled off by the peeling portion 17 to peel off the peeling material layer 151 and the other parts. The printed layer 154, the base material layer 153, and the pressure-sensitive adhesive layer 152 are separated into a printed tape 150 ″.

  As shown in FIGS. 2 and 5, the tape cartridge TK is formed by winding the peeled release material layer 151 around an axis O3 (corresponding to the second axis), as described above. It has a roll R3 (corresponding to a second tape roll). That is, when the tape cartridge TK is mounted as described above, the release material roll R3 is received from above into the second storage portion 5, and the release material layer winding axis O3 is stored in the left-right direction. The release material roll R3 is geared by a release paper take-up motor M3 provided on the interior substrate 2b of the housing body 2a in a state where the release material roll R3 is stored in the second storage unit 5 (a state where the tape cartridge TK is mounted). The release material layer 151 is wound up by being driven through a mechanism (not shown) and rotating in a predetermined rotation direction (C direction in FIG. 2) in the second storage unit 5.

  At this time, as shown in FIG. 5, the second bracket portions 21 and 21 of the tape cartridge TK place the release material roll R3 on the axis O3 via a pair of left and right substantially circular roll flange portions f3 and f4. The release material roll R3 is rotatably held around the axis O3 in a state where the tape cartridge TK is mounted on the housing body 2a so as to be sandwiched from both the left and right sides (details of the holding structure will be described later) ). 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.

  FIG. 5 shows a state before the release material layer 151 is wound around the axis O3 and the release material roll R3 is formed (in the case of an unused tape cartridge TK). That is, the substantially circular roll flange portions f3 and f4 provided so as to sandwich both sides in the width direction of the release material layer 151 are illustrated, and a symbol “R3” is provided at a place where the release material roll R3 is formed for convenience. Is attached.

<Printed tape roll and its surroundings>
On the other hand, as shown in FIGS. 2 and 4, a winding mechanism 40 for sequentially winding the printed tape 150 ″ is received in the third storage portion 4 from above. The printed tape 150 ″ is wound so as to be rotatably supported around the axis O 2 in a state where the axis O 2 of the wound tape 150 ″ is in the left-right direction. Then, in a state where the winding mechanism 40 is housed in the third housing portion 4, the winding mechanism 40 is driven via an unillustrated gear mechanism by an adhesive winding motor M <b> 2 provided inside the housing body 2 a, and the third The printed tape 150 ″ is wound and laminated by rotating in a predetermined rotation direction (the B direction in FIG. 2) in the storage unit 4. Thereby, the printed tape 150 is wound on the outer peripheral side of the winding mechanism 40. ″ Are sequentially wound to form a printed tape roll R2.

<Cutter mechanism 30>
As shown in FIG. 2, a cutter mechanism 30 is provided on the downstream side of the print head 11 and the upstream side of the printed tape roll R2 along the tape transport direction.

  Although not shown in detail, the cutter mechanism 30 includes a movable blade and a traveling body that supports the movable blade and can travel in the tape width direction (in other words, the left-right direction). Then, the traveling body travels by driving a cutter motor (not shown) and the movable blade moves in the tape width direction, thereby cutting the printed tape 150 ″ in the width direction.

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

  That is, when the tape cartridge TK is mounted at the first predetermined position 13, the print-receiving tape roll R1 is stored in the first storage portion 3 located on the rear side of the housing body 2a, and the front side of the housing body 2a. The axis O3 side that forms the release material roll R3 is stored in the second storage portion 5 located in the position. In addition, a winding mechanism 40 for forming the printed tape roll R2 is stored in the third storage portion 4 located on the front side of the housing body 2a.

  At this time, when the transport roller 12 is driven, the print-receiving tape 150 fed out by the rotation of the print-receiving tape roll R1 stored in the first storage unit 3 is transported to the front side. Then, a desired print is formed by the print head 11 on the print layer 154 of the print-receiving tape 150 being conveyed, and a printed tape 150 ′ is obtained. When the printed tape 150 ′ that has been printed is further conveyed to the front side and conveyed to the peeling portion 17, the peeling material layer 151 is peeled off at the peeling portion 17, and the printed adhesive tape 150 ″ is printed. The peeled release material layer 151 is conveyed downward and introduced into the second storage unit 5 and wound inside the second storage unit 5 to form a release material 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 third storage unit 4, and the outer peripheral side of the winding mechanism 40 in the third storage unit 4. In this case, the cutter mechanism 30 provided on the downstream side (that is, the front side) in the transport direction cuts the printed adhesive tape 150 ″. Accordingly, the printed adhesive tape 150 ″ wound around the printed tape roll R2 can be cut at a timing desired by the user, and the printed tape roll R2 can be taken out from the third storage unit 4 after cutting. .

  At this time, although not shown in the drawing, a non-adhesive tape (without the adhesive layer 152 and the release material layer 151) may be wound around the print-receiving tape roll R1. Also in this case, the first receiving portion 3 receives the print-receiving tape roll R1 around which the non-adhesive tape is wound by the attachment of the tape cartridge TK from above, and the axis O1 for winding the non-adhesive tape is provided. It is stored in a state that is in the left-right direction. The print-receiving tape roll R1 is in a predetermined rotation direction (A direction in FIG. 2) in the first storage unit 3 in a state where the print-receiving tape roll R1 is stored in the first storage unit 3 (a state where the tape cartridge TK is mounted). The non-adhesive tape is fed out by rotating in the direction.

  At this time, the chute 15 switches the transport path of the non-adhesive tape (or the print-receiving tape 150) between the side toward the printed tape roll R2 and the side toward the discharge port (not shown). (Refer FIG. 2) may be arranged. That is, by switching the tape path by the switching operation of the chute 15 by a switching lever (not shown), the non-adhesive tape (or the printed tape 150 ″) after printing is wound in the third storage portion 4 as described later. Without rotating, the housing 2 may be discharged out of the housing 2 as it is from a discharge port (not shown) provided on the second opening / closing cover 8b side, for example.

<Detailed structure near the roll axis>
One of the features of this embodiment is the detailed structure in the vicinity of the axes O1 and O3 of the print-receiving tape roll R1 and the release material roll R3 provided in the tape cartridge TK. Hereinafter, the details will be described in order.

<Details of print tape support structure>
As shown in FIG. 5, FIG. 7 and FIG. 8, the print-receiving tape roll R1 (corresponding to the first tape roll and the tape roll) includes a winding core 103 (corresponding to the first winding core). That is, the print-receiving tape roll R1 (corresponding to a tape roll) is configured by winding the print-receiving tape 150 on the outer periphery of the winding core 103 so that the print-receiving tape 150 can be fed out (= a roll-shaped wound body RR). Is done.

  The winding core 103 is rotatably supported by a fixed shaft member 106 (corresponding to a first fixed shaft member) in which a pair of left and right left fixed shaft portions 106L and right fixed shaft portions 106R are directly connected to each other. That is, the core 103 has a double tube structure of the outer cylinder 103A and the inner cylinder 103B. And the short cylinder part 115a located in the right end side of the left fixed shaft part 106L is slidably inserted from the left side of the inner cylinder 103B. At this time, a through hole 20L (shown schematically in FIG. 8) having an inner diameter larger than the outer diameter of the short cylinder portion 115a is provided in the first bracket portion 20 on the left side. And the short cylinder part 115a is inserted in the inner cylinder 103B of the said core 103 located in the other side (namely, right side) through the 1st bracket part 20, penetrating the said through-hole 20L.

  Similarly, the long cylindrical portion 115b located on the left end side of the right fixed shaft portion 106R is slidably inserted from the right side of the inner cylinder 103B. At this time, a through hole 20R (shown schematically in FIG. 8) having an inner diameter larger than the outer diameter of the long cylindrical portion 115b is provided in the first bracket portion 20 on the right side. And the long cylinder part 115b is inserted in the inner cylinder 103B of the said core 103 located in the other side (namely, left side) through the 1st bracket part 20, penetrating the said through-hole 20R.

  Thereafter, the locking pieces 111b of the right fixed shaft portion 106R are engaged with the locking holes 111a provided at a plurality of locations in the circumferential direction of the left fixed shaft portion 106L, so that the left and right fixed shaft portions 106L and 106R are engaged. They are connected and integrated. As a result, the winding core 103 is slidably rotated between the pair of left and right first bracket portions 20 and 20 with the fixed shaft member 106 including the left and right fixed shaft portions 106L and 106R as the fixed central axis. It becomes possible.

  At this time, a plurality of locking holes 103a are formed in the surface of the outer cylinder 103A along the axial direction. On the other hand, a circular opening fb is provided on the center side of the roll flange portions f1 and f2. A locking projection fa is formed on the inner peripheral edge of the circular opening gb. The roll flange portions f1 and f2 constitute the print-receiving tape roll R1 by fitting the respective locking projections fa of the roll flange portions f1 and f2 into any of the locking holes 103a of the outer cylinder 103A. It can be fixed at a position corresponding to the width of the print-receiving tape 150 (see also FIG. 15 described later).

  As described above, the left and right fixed shaft portions 106L and 106R constituting the fixed shaft member 106 have the short tube portion 115a and the long tube portion 115b (through the play size) with respect to the through holes 20L and 20R as described above. Inserted). However, the left and right fixed shaft portions 106L and 106R are non-rotatably engaged with the first bracket portions 20 and 20 by the positioning flange portions 105L and 105R provided respectively. That is, as shown in FIGS. 5 and 7, each first bracket portion 20 includes two upper and lower circular arc portions 104b and 104b and two front and rear straight portions 104a and 104a. The first guide portion 104 having a (small size) shape is provided in the vicinity of the lower end portion. On the other hand, the positioning flange portions 105L and 105R include two linear outer edge portions 105a and 105a formed in front and rear so as to be along the vertical direction (in other words, the self-weight operation direction). It has a substantially oval shape (slightly smaller than the portion 104). When the short cylindrical portion 115a is inserted into the through-hole 20L as described above, the positioning flange portion 105L is positioned on the outer edge portion 105a with respect to the first guide portion 104 of the left first bracket portion 20. , 105a are accommodated while being substantially along the straight portions 104a, 104a. Similarly, when the long cylindrical portion 115b is inserted into the through hole 20R, the positioning flange portion 105R (corresponding to the flange portion described in each claim) is the first guide portion 104 of the right first bracket portion 20. On the other hand, the outer edge portions 105a and 105a are accommodated while being substantially along the straight portions 104a and 104a. As a result, in the state where the left and right positioning flange portions 105L and 105 are accommodated in the first guide portions 104 and 104, the left and right fixed shaft portions 106L and 106R are opposed to the left and right first bracket portions 20 and 20, respectively. And engage non-rotatably. By engaging the positioning flange portions 105L and 105R with the first guide portion 104, all the components shown in FIG. 8 (fixed shaft member 106, print-receiving tape roll R1, left / right roll flange portion f1, Positioning in the installation direction of the shaft-equipped roll mechanism RM consisting of f2 is performed (details of positioning will be described later).

  With the above configuration, the roll flange portions f1 and f2 and the winding core 103 are integrated, and the fixed shaft member 106 that is locked to the first bracket portion 20 between the pair of left and right first bracket portions 20 and 20. Can rotate. Thus, the print-receiving tape roll R1 is supported so as to be rotatable about the axis O1 with respect to the first bracket portions 20 and 20, and the print-receiving tape 150 can be fed out by rotating.

<Memory built in the shaft end of the left fixed shaft>
As one of the features of the present embodiment, a memory 107 as a storage medium is provided on the left fixed shaft portion 106 </ b> L constituting the fixed shaft member 106. Hereinafter, the details will be described in order.

  As shown in FIGS. 9A to 9D and FIGS. 8, 7 and the like, the left fixed shaft portion 106L is on the opposite side (that is, the left side) of the short cylinder portion 115a with the positioning flange portion 105L interposed therebetween. A shaft end housing 121 is provided. The shaft end housing part 121 has an outer shape that is substantially D-shaped laterally when viewed from the axial direction. The memory 107 is built in the shaft end housing part 121.

  Further, an opening surface (in other words, a self-weight operation surface in the self-weight operation direction of the print-receiving tape roll R1) provided on the linear portion below the D-shape in the shaft end housing portion 121 is exposed on the surface. A terminal portion 107a is provided (see FIGS. 9D and 7).

  The terminal portion 107a is electrically connected to the memory 107. When the tape cartridge TK is mounted in the housing body 2a as described later (in other words, when the first guide portion 104 of the first bracket portion 20 described later is inserted into the first introduction groove 101 described later). ) Contacted from above the external terminal 207 (only conceptually shown in FIG. 4; see also FIG. 14 described later) provided on the inner peripheral side portion (details will be described later) of the left wall surface of the housing body 2a. , Conducted. Thereby, information reading and information writing can be performed from the housing 2 side with respect to the memory 107 provided by being connected to the terminal portion 107a.

  In the above, in the tape cartridge TK provided with the print-receiving tape roll R1 and the release material roll R3, the memory 107 is provided on the fixed shaft member 106 that rotatably supports the print-receiving tape roll R1. However, it is not limited to this. That is, as shown in FIG. 10 (the same parts as described above are given the same reference numerals), the print-receiving tape constructed around the roll flange portions f1 and f2 and the winding core 103 (not shown). In a roll mechanism RM with a shaft that rotates relative to the fixed shaft member 106 with the roll R1, a memory 107 may be provided for the fixed shaft member 106. In this case, the entire roll mechanism RM with the shaft is attached (for example, removable) to an appropriate fixing target portion by the left and right positioning flange portions 105L and the positioning flange portion 105R (not shown) of the fixed shaft member 106. Fixed. Then, at the time of the fixing, the terminal portion 107a comes into contact with the external terminal 207 provided at the fixing target portion and is conducted. Thereby, information reading and information writing can be performed from the outside of the shaft-equipped roll mechanism RM with respect to the memory 107 provided in connection with the terminal portion 107a.

<Detailed structure near the axis of the release material roll>
Returning to FIGS. 5 and 7, on the other hand, the release material roll R3 (corresponding to the second tape roll) has the same support structure as that of the print-receiving tape roll R1, although detailed illustration is omitted. That is, the release material roll R3 includes a winding core 108 (corresponding to a second winding core), and the release material layer 151 peeled off as described above is wound around the outer periphery of the winding core 108 and wound. The above-described release material roll R3 (corresponding to a tape roll) is configured by forming (= a roll-shaped wound body).

  The winding core 108 is rotatably supported by a fixed shaft member 110 (corresponding to a second fixed shaft member). The winding core 108 has a double tube structure of an outer cylinder and an inner cylinder, like the winding core 103. At this time, through holes (not shown) having an inner diameter larger than the outer diameter of the outer cylinder are provided in the left and right second bracket portions 21 and 21, respectively. Then, the shaft main body portion (portions corresponding to the short tube portion 115a and the long tube portion 115b, not shown) of the fixed shaft member 110 is slid onto the inner tube of the core 108 while passing through the through hole. It is inserted freely. As a result, the winding core 108 can slide and rotate between the pair of left and right second bracket portions 21 and 21 while using the fixed shaft member 110 as a fixed central axis.

  At this time, a plurality of locking holes are formed along the axial direction on the surface of the outer cylinder of the winding core 108, similarly to the locking holes 103 a of the winding core 103. On the other hand, locking projections (not shown) similar to the locking projections fa of the roll flange portions f1 and f2 are formed on the center side of the roll flange portions f3 and f4. Then, by fitting the respective locking projections of the roll flange portions f3 and f4 into the locking holes of any of the outer cylinders of the core 108, the roll flange portions f3 and f4 are moved to the release material roll R3. Can be fixed at a position corresponding to the width of the release material 151 (in other words, the width of the print-receiving tape 150).

  With the above configuration, the roll flange portions f3 and f4 and the core 108 can be integrated and rotated with respect to the fixed shaft member 110 between the pair of left and right second bracket portions 21 and 21. As a result, the release material roll R3 is supported by the second bracket portions 21 and 21 so as to be rotatable about the axis O3. At this time, the fixed shaft member 110 is operatively connected to the release paper take-up motor M3 via a gear mechanism (not shown), and is rotated by the driving force from the release paper take-up motor M3. The release material layer 151 peeled off from the printing tape 150 can be wound up.

<Guide at the time of wearing by the first and second guide portions>
Another feature of the present embodiment is that when the user mounts the tape cartridge TK in the housing body 2a, the user guides the tape cartridge TK to be mounted in a correct posture. Hereinafter, the details will be described in order.

<First guide portion and first introduction groove>
As already described, each first bracket portion 20 has the first guide portion 104 in the vicinity of the lower end portion. As shown in FIGS. 5 and 7, the first guide portion 104 includes two upper and lower arc portions 104 b and 104 b and two front and rear straight portions 104 a and 104 a in the substantially vertical direction. Overall, it has a substantially oval shape. Correspondingly, as shown in FIG. 4, a substantially U-shaped first introduction groove 101 is provided inside the first storage portion 3 of the housing body 2 a. The first introduction groove 101 includes parallel straight portions 101b and 101b that allow the first guide portion 104 to enter while restricting the entering direction (details will be described later). Thus, the first guide portion 104 guides the storage of the print-receiving tape roll R1 in the first storage portion 3 (details will be described later).

<Second guide portion and second introduction groove>
On the other hand, as shown in FIGS. 5 and 9, each second bracket portion 21 has a second guide portion 109 having a substantially circular frame shape in the vicinity of the lower end portion. Correspondingly, as shown in FIG. 4, a substantially inverted C-shaped second introduction groove 102 is provided inside the second storage portion 5 of the housing body 2 a. The second introduction groove 102 allows the second guide portion 109 to enter. As a result, the second guide portion 109 guides the release material roll R3 to be stored in the second storage portion 5 (details will be described later).

<Details of guide function>
Next, details of the guide function by the first guide portion 104 and the second guide portion 109 when the tape cartridge TK is mounted will be described with reference to FIGS. 11 and 12.

  As described above, when the user mounts the tape cartridge TK, the print-receiving tape roll R1 is stored in the first storage unit 3 and the release material roll R3 is stored in the second storage unit 5. The In this case, since the printing tape roll R1 side is usually heavier than the release material roll R3 side (especially, when not used, the release material roll R3 is not formed), the first guide portion 104 is first formed. 1 is introduced into the introduction groove 101. That is, as shown in FIG. 11, the first guide portion 104 is first introduced into the first introduction groove 101 with the light release material roll R3 side slightly inclined upward. At this time, while the major axis direction of the first guide portion 104 (that is, the direction of the straight portions 104a and 104a) does not coincide with the direction of the parallel straight portions 101b and 101b of the substantially U-shaped first introduction groove 101, The first guide portion 104 enters an entry restriction state in which the first guide portion 104 is placed on the inlet portion 101a of the first introduction groove 101, and the first guide portion 104 does not enter the first introduction groove 101 (state of FIG. 11).

  In this entry restriction state, the tape cartridge TK can take various postures with the first guide portion 104 placed on the inlet portion 101a of the first introduction groove 101. In this case, as shown in FIG. 11, along with the change in the posture of the tape cartridge TK, the outer shape of the release material roll R3 is generally an arc shape centered around the inlet portion 101a of the first introduction groove 101. Draw a trajectory C.

  Then, after the release material roll R3 that draws the locus C as described above with the change in the posture of the tape cartridge TK gets over the conveyance roller 12 and does not interfere with the conveyance roller 12, the entry restriction state is changed to FIG. It switches to the entry permission state shown in. That is, in this approach permitting state, the long axis direction of the first guide portion 104 (that is, the direction of the straight portions 104a and 104a) is the same as the direction of the parallel straight portions 101b and 101b of the substantially U-shaped first introduction groove 101. Match. As a result, the first guide portion 104 can enter the first introduction groove 101. After the left and right first guide portions 104 and 104 have entered the left and right first introduction grooves 101 and 101, the fixed shaft member 106 is moved to the left and right sides of the housing body 2a. Left and right support recesses 190, 190 (only the right support recess 190 is shown in FIG. 4 are shown at positions further left and right outward of the right first introduction grooves 101, 101. The fixing target according to each claim (Corresponding to the part) and fixed (removably later). As a result, the weight of the print-receiving tape roll R1 applied to the fixed shaft member 106 is mainly supported by the left and right support recesses 190 and 190. The external terminal 207 described above is provided in the left support recess 190.

  When the first guide portion 104 enters the first introduction groove 101, the second guide portion 109 is guided by the second introduction groove 102 and enters. At this time, the second guide portion 109 of the tape cartridge TK has a substantially circular shape, and the second introduction groove 102 of the second storage portion 5 has a substantially inverted C shape. Therefore, the second guide portion 109 can be easily entered (regardless of the posture of the tape cartridge TK).

<Residual amount detection of tape roll to be printed by encoder>
Next, detection of the remaining amount of the print-receiving tape 150 in the print-receiving tape roll R1, which is still another feature of the present embodiment, will be described with reference to FIG. As shown in FIG. 13, a convex portion 100b for detecting the remaining amount (in other words, consumption) of the print-receiving tape 150 is provided along the circumferential direction on the outer peripheral surface of the inner cylinder 103B constituting the winding core 103. Are formed at regular intervals. A recess 100a is provided between each detected protrusion 100b. The convex portions 100b and the concave portions 100a correspond to detected identifiers for optical detection.

  As described above, when the winding core 103 is slidably supported around the fixed shaft member 106 between the pair of left and right first bracket portions 20 and 20, the right end portion of the outer cylinder 103A is on the right side. Although it does not penetrate the through hole 20R of the first bracket part 20, the right end part (including the convex part 100b and the concave part 100a) of the inner cylinder 103B penetrates the through hole 20R and is more than the first bracket part 20 on the right side. Furthermore, it is exposed to the outside on the right side. As a result, the first bracket portion 20 on the right side covers the outer peripheral side in the radial direction of the convex portion 100b and the concave portion 100a, and the positioning flange portion 105R of the right fixed shaft portion 106R is in the axial direction of the convex portion 100b and the concave portion 100a. One side (in this example, the right side) will be covered.

  At this time, as shown in FIG. 3 described above, an encoder 100 (corresponding to a detecting means) that performs optical detection by a known method is provided on the right inner side wall of the first storage unit 3 corresponding to the above. ing. For example, the encoder 100 includes a projector and a light receiver. When the tape cartridge TK is mounted as described above, the position of the encoder 100 is a position facing the right positioning flange portion 105R along the axis O1. At this time, the convex portion 100b and the concave portion 100a of the winding core 103 are located on the opposite side (left side) of the positioning flange portion 105R to the encoder 100. And the detection flange 105c for encoder detection is formed in the positioning flange part 105R (refer FIG. 8). Thereby, the light from the projector can be applied to the convex part 100b or the concave part 100a along the direction of the axis O1 while passing through the detection hole 105c.

  When the convex portion 100b is positioned on the light beam (for example, parallel to the axis O1) of the light from the projector according to the rotation state of the inner cylinder 103B of the core 103, the light is reflected by the convex portion 100b. Then, the light passes through the detection hole 105c in the opposite direction and is emitted again, and is received by the light receiver. As a result, a predetermined detection signal corresponding to the light reception is output from the light receiver. On the other hand, when the concave portion 100a is positioned on the light beam from the projector, no light is received by the light receiver as described above (or the amount of light received is extremely small). As a result, a detection signal corresponding to the light reception is not output from the light receiver. As described above, as a result of rotation of the core 103 (in other words, rotation of the print-receiving tape roll R1), the concave portion 100a and the convex portion 100b alternately come on the light beam, the ON / OFF of the detection signal from the light receiver is turned on. Repeated according to the period corresponding to the rotation speed. Thereby, based on the length of the said period, the rotational speed of the said to-be-printed tape roll R1 is detectable.

  When the tape cartridge TK is used, the diameter of the print-receiving tape roll R1 decreases as the print-receiving tape roll 150 is fed out and consumed from the print-receiving tape roll R1, and as a result, the same tape supply speed is obtained. However, the roll rotation speed, in other words, the rotation speed of the inner cylinder 103B of the core 103 is increased. As a result, the rotational speed of the core 103, that is, the print-receiving tape roll R1, is calculated based on the detection result of the encoder 100 as described above (although the detailed description is omitted because it is a known technique). The degree of diameter reduction of the print-receiving tape roll R1, that is, the remaining tape amount can be calculated.

  As a result, the concave portion 100a and the convex portion 100b are provided on the right side of the core 103 on the opposite side to the left fixed shaft portion 106L of the fixed shaft member 106 in which the memory 107 is provided.

<Control system>
Next, the control system of the tape printer 1 will be described with reference to FIG. In FIG. 9, the 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 tape printer 1.

  The CPU 212 also controls the motor drive circuit 218 that controls the transport motor M1 that drives the transport roller 12, and the motor that controls the drive of the adhesive take-up motor M2 that drives the printed tape roll R2. A drive circuit 219, a motor drive circuit 220 that controls the drive of the release paper winding motor M3 that drives the release material roll R3, a print head control circuit 221 that controls energization of the heating elements of the print head 11, It is connected to a display unit 215 that performs appropriate display, and an operation unit 216 that can be appropriately input by the user.

  Further, in the present embodiment, the encoder 100 is connected to the CPU 212. As a result, as described above, the detection signal from the light receiver of the encoder 100 is input to the CPU 212, and based on the ON / OFF cycle of the detection signal (corresponding to the rotational speed of the core 103), The rotation speed is detected by the CPU 212.

  Further, in the present embodiment, the external terminal 207 is connected to the CPU 212. Thus, as described above, when the external terminal 207 is brought into contact with the terminal portion 107a to conduct, information can be read from or written to the memory 107.

  The ROM 214 stores a control program for executing predetermined control processing. The RAM 213 includes an image buffer 213 a that stores, for example, print data in an image data format received from a PC (not shown) as dot pattern data for printing in a predetermined print area of the print target layer 154. It has been. The CPU 212 feeds the concavo-convex tape 153 by the transport roller 12 according to an appropriate control program stored in the ROM 214, and the print head 11 via the print head control circuit 221 according to the print data stored in the image buffer 213a. Printing corresponding to is performed.

<Effects of this embodiment>
As described above, in this embodiment, the core 103 around which the print-receiving tape roll R1 is wound is supported by the fixed shaft member 106 so as to be rotatable. As a result, as described above, when the tape cartridge TK is mounted, the weight of the print-receiving tape roll R1, which is a rotating body, is mainly applied to the fixed shaft member 106 (the left fixed shaft portion 106L and the right fixed shaft portion 106R). Join. The memory 107 described above is provided on the left fixed shaft portion 106L together with the terminal portion 107a. Thereby, the contact between the external terminal 207 and the terminal portion 107a can be performed stably and reliably as compared with the case where the memory 107 and the terminal portion 107a are provided in other parts where the weight is not so much applied. Thereby, the above-described information reading or information writing to the memory 107 can be performed with high reliability.

  Further, particularly in the present embodiment, the terminal portion 107a is provided on the self-weight acting surface of the print-receiving tape roll R1 in the shaft end housing portion 121. As a result, the dead weight can be reliably applied to the terminal portion 107a, and the external terminal 207 and the terminal portion 107a can be reliably contacted.

  Further, particularly in the present embodiment, each of the positioning flange portions 105L and 105R includes linear outer edge portions 105a and 105a along the action direction (vertical direction) of the own weight. As a result, when the left fixed shaft portion 106L is fixed to the support recess 190, the print-receiving tape roll R1 ensures that its own weight acts in a direction in which the terminal portion 107a and the external terminal 207 come into contact with each other. It is possible to position the entire roll mechanism RM with shaft including RM (see FIG. 8) in the installation direction.

  In the present embodiment, the first guide portion 104 of the first bracket portion 20 includes two front and rear straight portions 104a and 104a in the substantially vertical direction, and has a substantially oval shape. ing. Further, a substantially U-shaped first introduction groove 101 having parallel straight portions 101b, 101b is provided in the housing body 2a. When the user mounts the tape cartridge TK in the housing main body 2a, the direction of the straight portions 104a and 104a of the first guide portion 104 is the same as that of the substantially U-shaped first introduction groove 101. The first guide portion 104 is not allowed to enter the first introduction groove 101 as long as it does not coincide with the direction of the parallel straight portions 101b and 101b. When the posture of the tape cartridge TK changes and the direction of the straight portions 104a and 104a coincides with the direction of the parallel straight portions 101b and 101b, the first guide portion 104 enters the first introduction groove 101. Thus, only when the tape cartridge TK is in a predetermined posture, the storage of the tape tape R1 to be printed in the first storage unit 3 and the storage of the release material roll R3 in the second storage unit 5 are performed. Can be executed. As a result, it is possible to prevent the tape cartridge TK from being mounted on the tape printer 1 in an inappropriate posture by the user, so that the durability of the tape cartridge TK or the tape printer 1 due to collision or interference during mounting can be prevented. A decrease or the like can be prevented.

  Further, in the present embodiment, in order to detect the remaining amount (in other words, consumption) of the print-receiving tape 150, the convex portion 100b and the concave portion 100a serving as detection identifiers to be optically detected are: Of the print-receiving tape roll R1, for example, it is formed on the winding core 103 instead of the roll body (roll-shaped winding body RR), the roll flange portions f1, f2, and the like. This has the following significance.

  That is, there may be a need to use a plurality of types of widths of the print-receiving tape 150. In this embodiment, it is the structure which can respond to such needs. For example, when a wide print-receiving tape 150 is used, as shown in FIG. 15A, the above-described locking projections fa of the roll flange portions f1 and f2 correspond to the maximum width of the outer cylinder 103A. The print-receiving tape roll R1 may be constructed by fitting the print-receiving tape 150 between the roll flange portions f1 and f2 by being fitted to the positions of the locking holes 103a.

  On the other hand, when the narrow print-receiving tape 150 is used, as shown in FIG. 15B, the locking projections fa of the roll flange portions f1 and f2 are set to the minimum width of the outer cylinder 103A. The print-receiving tape roll R1 may be constructed by fitting the print-receiving tape 150 between the roll flange portions f1 and f2, respectively, by fitting the corresponding lock holes 103a. Thus, the above-mentioned needs can be met by appropriately selecting the attachment positions of the roll flange portions f1, f2 with respect to the core 103 according to the width of the print-receiving tape roll R1.

  Here, if the structure is such that the detected identifier is provided on the roll body, the flange, or the like as described above, the encoder 100 performs the optical processing from one side in the axial direction of the printing tape roll R1 (from the right in the above example). When the detection is performed, the distance from the encoder 100 to the detected identifier varies depending on whether the tape width of the print-receiving tape 150 is wide or narrow. As a result, the detection accuracy is not constant, and it may be difficult to ensure high detection accuracy.

  On the other hand, in the present embodiment, the convex portion 100b and the concave portion 100a as the detected identifier are provided on the inner cylinder 103B of the core 103 as described above. As a result, even when tapes having a plurality of types of wide and narrow widths are used in the print-receiving tape roll R1, the convex portion of the core 103 is transferred from the encoder 100 (if the core 103 is shared by all the rolls). The distance x to 100b and the recessed part 100a can be made constant (refer FIG. 15 (a) and FIG.15 (b)). As a result, unlike the above, since the detection accuracy can be made constant, the remaining amount of the tape to be printed 150 can be detected stably and with high accuracy.

  At this time, in the present embodiment, as described above, the first bracket portion 20 on the right side covers the outer circumferential side of the convex portion 100b and the concave portion 100a, and the positioning flange portion 105R of the right fixed shaft portion 106R The right side of the convex part 100b and the concave part 100a is covered. As a result, the convex portion 100b and the concave portion 100a can be protected against dust and dirt while the optical detection is not hindered by the detection hole 105c of the positioning flange portion 105R as described above. Therefore, this also makes it possible to increase the accuracy of the remaining amount detection.

  In the present embodiment, in particular, the memory 107 is provided on the fixed shaft member 106. Thereby, even if the tape cartridge TK is used while being repeatedly attached to and detached from the tape printer 1, the tape cartridge TK itself can always hold the tape remaining amount information of the print-receiving tape roll R1 by the memory 107. . As a result, the CPU 212 reads the remaining tape amount information held in the memory 107 as described above, so that the accurate remaining tape amount of the tape to be printed 150 can be obtained with certainty. In addition, the memory 107 is provided on the left fixed shaft portion 106L on the opposite side of the fixed shaft member 106 from the side on which detection by the convex portion 100b and the concave portion 100a is performed (right side in this example). Thereby, in the tape printer 1, the encoder 100 for detecting the convex portion 100b and the concave portion 100a and the external terminal 207 (corresponding to the read / write means) for reading and writing information to the memory 107 are connected to one side. Therefore, it is possible to secure the degree of freedom of layout.

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

  In the above, the arrow shown in FIG. 14 shows an example of the signal flow, and does not limit the signal flow direction.

  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.
