Description

  The present invention relates to a tape feeding apparatus and a tape printing apparatus for feeding a tape-shaped member such as a printing tape.

  Conventionally, as a tape printer, a platen roller and a print head that perform printing while feeding the print tape, a full cut mechanism that cuts the print tape, and a discharge roller and a discharge auxiliary roller allow the cut tape piece to be outside the device. A tape piece discharging mechanism that forcibly discharges is known (see Patent Document 1). The paper discharge roller of the tape piece discharge mechanism rotates in synchronization with the cutting operation of the cutter.

JP 2002-167092 A

However, in such a configuration, since the rotation of the discharge roller is stopped at the time of tape feeding, when the leading end of the printing tape reaches the tape piece discharge mechanism by tape feeding, the discharge roller and the discharge auxiliary roller There is a problem that the front end of the printing tape is clogged (jamming) at the sandwiched portion.
In contrast, a configuration in which jamming is prevented by rotating the discharge roller in conjunction with the platen roller is conceivable. However, in such a configuration, not only the discharge roller but also the platen roller is used when discharging the tape piece. There was a problem that the tape was rotated and unnecessary tape feeding was performed. In particular, when the printing tape and the ink ribbon are sent simultaneously by the platen roller, the ink ribbon is also sent unnecessarily.

  It is an object of the present invention to provide a tape feeding device and a tape printing device that can suitably discharge a cut-off portion of a tape-like member without preventing unnecessary tape feeding while preventing jamming of the tape-like member. It is said.

  The tape feeding device of the present invention includes a feeding unit that feeds a tape-shaped member, a cutting unit that is disposed on the downstream side of the feeding unit in the tape feeding direction, and that performs a cutting operation for cutting the tape-shaped member that has been fed, And a discharge means for sending the tape-like member toward the outside of the apparatus, and before the cutting operation, the feeding means and the discharge means are driven in conjunction with each other to provide the tape-like member. After the cutting operation, the discharging means is driven without driving the feeding means, and the cut-off portion of the separated tape-like member is discharged out of the apparatus.

  According to this configuration, before the cutting operation (at the time of tape feeding), the ejection unit is driven in conjunction with the feeding unit, so that jamming of the tape-like member in the ejection unit can be prevented. On the other hand, after the cutting operation (when the cut-off portion is discharged), the discharging means is driven without driving the feeding means, so that the cutting portion (tape piece) of the tape-like member is not driven without unnecessary tape feeding. It can discharge suitably. Thus, the tape-shaped member is not only driven in conjunction with the feeding means and the discharging means, but also after the cutting operation of the cutting means, by driving only the discharging means, thereby preventing jamming of the tape-shaped member. Can be suitably discharged.

  In this case, the power transmission mechanism further includes a single motor that can rotate in the forward and reverse directions as a driving source for the feeding unit and the discharging unit, and a power transmission mechanism that transmits the rotational power of the motor to the feeding unit and the discharging unit. The transmission side gear train for transmitting the input power to the feed means, the discharge side gear train for transmitting the input power to the discharge means, and the forward rotation power of the motor for the feed side gear train and the discharge side gear train And a clutch mechanism for transmitting the reverse rotation power of the motor to the discharge side gear train while cutting off the power to the feed side gear train.

  According to this configuration, since the power transmission mechanism having the clutch mechanism is provided, the feeding unit and the discharging unit are interlocked before the cutting operation without separately providing a driving source for the feeding unit and the discharging unit. And after the cutting operation, only the discharging means can be driven. That is, the feeding means and the discharging means can be used as a motor. Further, the driving of the feeding means and the driving of the discharging means can be easily linked.

  In this case, the clutch mechanism rotatably supports the sun gear to which the motor power is input, the first planetary gear and the second planetary gear meshing with the sun gear, and the first planetary gear and the second planetary gear. A carrier that rotates with the rotation of the sun gear, and the rotation of the carrier with the forward rotation of the motor causes the first planetary gear to move to the feed side connection position that is connected to the input side of the feed side gear train. The second planetary gear moves to the second discharge side connection position connected to the input side of the discharge side gear train, and the first planetary gear is moved to the discharge side by the rotation of the carrier accompanying the reverse rotation driving of the motor. It is preferable that the second planetary gear is moved to a non-connection position where it is disconnected from the feed side gear train and the discharge side gear train.

  According to this configuration, when the motor is driven to rotate in the forward direction, the first planetary gear is connected to the input side of the feed side gear train, and the second planetary gear is connected to the input side of the discharge side gear train. As a result, the power of the motor input to the sun gear is branched and transmitted to the feeding means and the discharging means via each planetary gear and each gear train, thereby driving the feeding means and the discharging means. On the other hand, when the motor is driven in reverse rotation, the first planetary gear is connected to the input side of the discharge side gear train, and the second planetary gear is not connected to either the feed side gear train or the discharge side gear train. Become. As a result, the power of the motor input to the sun gear is not transmitted to the sending means, but is transmitted to the discharging means via the first planetary gear and the discharging side gear train, and drives only the discharging means. In this way, the clutch mechanism can be made simple by using a mechanism to which the planetary gear mechanism is applied.

  In this case, the discharge side gear train is engaged with the first input gear engaged with the first planetary gear moved to the first discharge side connection position and the second input engaged with the second planetary gear moved to the second discharge side connection position. The positive rotation power of the motor is preferably input to the first input gear via the second input gear.

  According to this configuration, since the positive rotation power of the motor is input to the first input gear via the second input gear, the first input gear is rotated during the normal rotation of the motor and during the reverse rotation of the motor. The direction of rotation is the same direction. Therefore, transmission of forward / reverse rotational power can be made common at the time of the first input gear, and the discharge side gear train can be configured simply.

  In this case, it is preferable that the discharge side gear train further includes a relay gear that is fixed on the same axis as the second input gear and transmits the rotation of the second input gear to the first input gear at a reduced speed.

  According to this configuration, the forward rotation power of the motor is decelerated from the second input gear and input to the first input gear by the relay gear, so that the first rotation when the motor is driven to rotate reversely (when the separated portion is discharged). The number of rotations of one input gear can be increased as compared with when the motor is driven forward (tape feed). As a result, when the cut-off portion is discharged, the discharge means can be driven at a higher speed than when the tape is fed, and the cut-off portion can be discharged quickly (or vigorously).

  A tape printer of the present invention comprises the above-described tape feeder and a print head that performs a printing process on the tape-like member that is fed by the tape feeder, and the cutting means performs printing with the print head. A cutting operation for cutting the printed portion of the tape-like member is performed.

  According to this configuration, it is possible to provide a tape printing apparatus capable of suitably discharging the cut-off portion of the printing tape without unnecessary tape feeding while preventing jamming of the printing tape.

  As shown in FIGS. 1 and 2, the tape printer 1 contains a device main body 2 that performs a printing process on the print tape T, a printing tape T, and an ink ribbon R, and is detachably attached to the device main body 2. A tape cartridge C. In the tape cartridge C, a printing tape T as a printing object is accommodated so as to be fed out.

  In the apparatus main body 2, an outer shell is formed by an apparatus case 3, and a keyboard 5 having various keys 4 is disposed on the upper surface of the front half of the apparatus case 3. On the other hand, an opening / closing lid 6 is widely provided on the upper left surface of the rear half of the device case 3, and a lid opening button 8 for opening the opening / closing lid 6 is provided on the front side of the opening / closing lid 6. Further, a rectangular display 9 for displaying an input result from the keyboard 5 and the like is disposed on the upper right side of the rear half of the device case 3.

  When the lid opening button 8 is pressed to open the opening / closing lid 6, a cartridge mounting portion 10 into which the tape cartridge C is detachably mounted is formed in the inside thereof, and the tape cartridge C opens the opening / closing lid 6. In the opened state, it is detachably mounted on the cartridge mounting portion 10. That is, the opening / closing lid 6 opens and closes the cartridge mounting portion 10. Further, the open / close lid 6 is formed with a viewing window 13 for visually confirming whether the tape cartridge C is mounted or not mounted in a state in which the lid 6 is closed.

  A tape discharge port 17 connected to the cartridge mounting portion 10 is formed on the left side of the apparatus case 3, and a tape discharge path 18 is formed between the cartridge mounting portion 10 and the tape discharge port 17. In the apparatus case 3, a tape cutting mechanism (cutting means) 11 that cuts the printing tape T that has been fed from the upstream side in the tape feeding direction so as to face the tape discharge path 18, and the separated printing tape A tape discharge mechanism (discharge means) 12 for discharging the cut-off portion of T from the tape discharge port 17 is assembled and incorporated (details will be described later).

  On the other hand, the cartridge mounting unit 10 includes a thermal type print head 21 having a plurality of heating elements in the head cover 20, a platen drive shaft 23 facing the print head 21, and a winding drive for winding an ink ribbon R described later. A shaft 24 and a positioning projection 25 of a tape reel 32 to be described later are disposed. The platen drive shaft 23 and the take-up drive shaft 24 pass through the bottom plate 27 of the cartridge mounting portion 10. The platen drive shaft 23 and the take-up drive shaft 24 are driven in the space below the bottom plate 27, and the tape discharging mechanism. A feed / discharge power system 26 (see FIG. 4) for driving 12 is disposed.

  As shown in FIG. 2, the tape cartridge C rotates a tape reel 32 around which the printing tape T is wound, and a ribbon reel 33 around which the ink ribbon R is wound at the lower right portion, in the upper center of the cartridge case 31. The printing tape T and the ink ribbon R are configured to have the same width. A through hole 34 is formed in the lower left portion of the tape reel 32 to be inserted into the head cover 20 that covers the print head 21. Further, in the vicinity of the through-hole 34, a platen roller 35 that is fitted to the platen drive shaft 23 and is driven to rotate is disposed corresponding to a portion where the printing tape T and the ink ribbon R overlap. On the other hand, a ribbon take-up reel 36 that is fitted to the take-up drive shaft 24 and driven to rotate is disposed in the vicinity of the ribbon reel 33.

  When the tape cartridge C is mounted on the cartridge mounting unit 10, the through hole 34 is formed in the head cover 20, the center hole of the tape reel 32 is positioned in the positioning protrusion 25, and the center hole of the platen roller 35 is driven in the platen drive shaft 23. The center hole of the ribbon take-up reel 36 is inserted into the shaft 24. By the rotational drive of the platen drive shaft 23 and the take-up drive shaft 24, the printing tape T is fed out from the tape reel 32, and the ink ribbon R is fed out from the ribbon reel 33. The fed printing tape T and ink ribbon R are overlapped and run at the position of the through hole 34, and then the printing tape T is sent out of the apparatus of the cartridge case 31, and the ink ribbon R is fed to the ribbon take-up reel 36. It is wound up. In a portion where the print tape T and the ink ribbon R run side by side, the platen roller 35 and the print head 21 face so as to sandwich them, and so-called print feed is performed. The feeding means includes a platen drive shaft 23 and a platen roller 35. Strictly speaking, the platen drive shaft 23 and the take-up drive shaft 24 include a support pin and a spline member rotatably attached to the support pin, and the spline member is associated with the platen roller 35 or the ribbon take-up reel 36. The platen roller 35 or the ribbon take-up reel 36 is rotated by the rotation of the spline member. Here, the rotation and rotation drive of the spline member are expressed as rotation and rotation drive of the platen drive shaft 23 or the winding drive shaft 24.

  The printing tape T is composed of a recording tape Ta having a pressure-sensitive adhesive layer formed on the back surface and having the surface as a printing surface, and a release tape Tb adhered to the recording tape Ta by the pressure-sensitive adhesive layer. The printing tape T is wound and accommodated on the tape reel 32 with the recording tape Ta on the outside and the release tape Tb on the inside. In addition, a plurality of types of printing tapes T different in tape type (tape width, ground color of the printing tape T, ground pattern, material (texture), etc.) are prepared. Is housed together.

  When the tape cartridge C is mounted on the cartridge mounting portion 10 and the opening / closing lid 6 is closed, the print head 21 rotates via a head release mechanism (not shown), and the print head 21 and the platen roller 35 are With the print tape T and the ink ribbon R sandwiched therebetween, the tape printer 1 enters a print standby state. After printing data is input / edited, when a printing operation is instructed from a control unit (not shown), the platen roller 35 is driven to rotate, the printing tape T is fed out from the tape cartridge C, and the printing head 21 is driven. The printing process is performed on the printing tape T that is being sent. At the same time as the printing operation, the ink ribbon R is wound up in the tape cartridge C, and the printed portion of the printing tape T is sent out of the apparatus from the tape discharge port 17. When printing is completed, the printed portion of the printing tape T is cut while the printing tape T is half cut by the tape cutting mechanism 11. Thereby, a label on which a desired character or the like is printed is created. The cut tape piece is discharged from the tape discharge port 17 by driving the tape discharge mechanism 12. The tape feeding device is constituted by the feeding means (the platen drive shaft 23 and the platen roller 35), the tape cutting mechanism 11, and the tape discharging mechanism 12.

  Here, with reference to FIG. 3 thru | or FIG. 6, the tape cutting mechanism 11, the tape discharge mechanism 12, and the feed discharge power system 26 are each demonstrated. As shown in FIG. 3, the tape cutting mechanism 11 includes a scissors-type full cutter 41 that fully cuts the printing tape T, a press-cut half cutter 42 that half-cuts the printing tape T, and a cutter motor that serves as a power source. 43 and a cutter power transmission mechanism 44 that transmits the power of the cutter motor 43 to the full cutter 41 and the half cutter 42. That is, the cutter motor 43 is also used as a power source for the full cutter 41 and the half cutter 42. Further, the “full cut” referred to here is a cutting operation that cuts the entire printing tape T, that is, the recording tape Ta and the release tape Tb integrally, and the “half cut” means that the release tape Tb is not cut. The cutting operation cuts only the recording tape Ta.

  The tape discharge mechanism 12 includes a drive roller portion 51 having a discharge drive roller 61 and a driven roller portion 52 having a discharge driven roller 63 facing the discharge drive roller 61.

  The drive roller unit 51 includes a discharge drive roller 61 that is in rolling contact with the peeling tape Tb side of the printing tape T, and a drive roller holder 62 that rotatably holds the discharge drive roller 61. The discharge driving roller 61 is formed with a gear portion 61 a and is rotated by the power input from the feed / discharge power system 26.

  On the other hand, the driven roller unit 52 includes a discharge driven roller 63 that is in rolling contact with the recording tape Ta side of the printing tape T, and a driven roller holder 64 that rotatably holds the discharge driven roller 63. That is, the tape discharge mechanism 12 sends the printing tape T toward the outside of the apparatus by a nip roller composed of the discharge drive roller 61 and the discharge driven roller 63.

  As shown in FIG. 4, the feed / discharge power system 26 includes a drive motor (motor) 71 that can rotate forward and backward as a power source, and the rotational power of the drive motor 71 by the platen drive shaft 23, the take-up drive shaft 24, and the discharge. A power transmission mechanism 72 that transmits to the drive roller 61. That is, the drive motor 71 is shared as a power source for the platen drive shaft 23, the winding drive shaft 24, and the discharge drive roller 61. The drive motor 71 is controlled to be switched between forward rotation drive and reverse rotation drive by the control unit.

  The power transmission mechanism 72 includes a clutch mechanism 76 that receives power from the drive motor 71, a feed-side gear train 77 that transmits power input from the clutch mechanism 76 to the platen drive shaft 23 and the take-up drive shaft 24, and a clutch. A discharge-side gear train 78 that transmits the power input from the mechanism 76 to the discharge drive roller 61. Although details will be described later, the clutch mechanism 76 transmits the normal rotational power of the drive motor 71 to the feed side gear train 77 and the discharge side gear train 78, and the reverse rotational power of the drive motor 71 is transmitted only to the discharge side gear train 78. To communicate.

  The clutch mechanism 76 meshes with a clutch input gear 101 that meshes with a gear formed on the drive shaft of the drive motor 71, a sun gear 102 that is coaxially fixed with the clutch input gear 101, and a sun gear 102. The first planetary gear 103 and the second planetary gear 104, the first planetary gear 103 and the second planetary gear 104 are rotatably supported, and the carrier 105 (clutch is supported on the same axis as the sun gear 102). Lever). The clutch mechanism 76 moves the first planetary gear 103 and the second planetary gear 104 in a planetary orbit by the rotation of the carrier 105 accompanying the rotational drive of the drive motor 71.

  As shown in FIG. 5, the carrier 105 is set around a substantially isosceles triangular plate-like carrier body 111 and a support shaft on the carrier body 111, and has a substantially “U” that generates rotational friction necessary for rotation. And a U-shaped spring 112 having a letter shape. The carrier main body 111 has two support portions 111a that rotatably support the first planetary gear 103 and the second planetary gear 104 at corners at both ends of the bottom side portion, and is rotatable coaxially with the sun gear 102. It is supported by.

  As shown in FIG. 6A, when the drive motor 71 is driven to rotate in the forward direction, the carrier 105 is rotated (rotated) by the forward rotation of the clutch input gear 101 and the sun gear 102, and the first planetary gear 103 is rotated. Moves to the feed side connection position P1 connected to the input side of the feed side gear train 77, and the second planetary gear 104 moves to the second discharge side connection position P2 connected to the input side of the discharge side gear train 78. . On the other hand, as shown in FIG. 6B, when the drive motor 71 is driven in the reverse rotation, the carrier 105 is rotated (rotated) by the reverse rotation of the clutch input gear 101 and the sun gear 102, and the first planet. The gear 103 moves to the first discharge side connection position P3 connected to the input side of the discharge side gear train 78, and the second planetary gear 104 is disconnected from the feed side gear train 77 and the discharge side gear train 78. Move to connection position P4. As a result, the clutch mechanism 76 transmits the normal rotational power of the drive motor 71 to the feed side gear train 77 and the discharge side gear train 78, and the reverse rotational power of the drive motor 71 is cut off from the feed side gear train 77. However, it is transmitted to the discharge side gear train 78.

  As shown in FIGS. 4 and 6, the feed side gear train 77 includes a feed side input gear 81 that meshes with the first planetary gear 103 moved to the feed side connection position P <b> 1, and a feed side on the same side as the feed side input gear 81. The feed side first intermediate gear 82 fixed to the lower side of the input gear 81, the feed side second intermediate gear 83 meshing with the feed side first intermediate gear 82, and the feed side second intermediate gear 83 coaxially with the feed side A branch gear 84 fixed on the upper side of the second intermediate gear 83, a feed-side first output gear 85 that meshes with the branch gear 84 and rotates the winding drive shaft 24, and a branch gear 84 similarly. A meshing reduction gear 86, a feed-side third intermediate gear 87 fixed on the upper side of the reduction gear 86 on the same axis as the reduction gear 86, and a feed-side third intermediate gear 87, and a platen drive shaft 23 mounted on the shaft. Rotate It has a feeding-side second output gear 88, the to. When power is input to the feed-side input gear 81, the platen drive shaft 23 and the take-up drive shaft 24 rotate through the respective gears. Thus, the ink ribbon R is transported in synchronization with the tape feed of the printing tape T.

  The discharge-side gear train 78 includes a discharge-side second input gear (second input gear) 91 that meshes with the second planetary gear 104 moved to the second discharge-side connection position P2, and a discharge side coaxially with the discharge-side input gear 91. A relay gear 92 fixed to the lower side of the second input gear 91 and a discharge-side first input gear (first gear) meshed with the relay gear 92 and meshed with the first planetary gear 103 moved to the first discharge-side connection position P3. Input gear) 93 and six intermediate gears, the input side meshing with the discharge side first input gear 93 and the output side of the intermediate gear train 94, and the gear portion 61a of the discharge drive roller 61. And a discharge-side output gear 95 that meshes with each other. That is, power is input from the first planetary gear 103 to the discharge-side first input gear 93 when the drive motor 71 rotates forward with respect to the discharge-side gear train 78. On the other hand, when the drive motor 71 rotates in the reverse direction, power is input from the second planetary gear 104 to the discharge-side first input gear 93 via the discharge-side second input gear 91. Further, the relay gear 92 decelerates and transmits the rotation of the discharge-side second input gear 91 to the discharge-side first input gear 93. That is, the positive rotational power of the drive motor 71 is input to the discharge-side first input gear 93 at a reduced speed via the discharge-side second input gear 91 and the relay gear 92, so The rotational speed of the 1-input gear 93 is smaller than that during reverse rotation driving. That is, the rotation speed of the discharge drive roller 61 is reduced.

  As a result, as shown in FIG. 6A, the power transmission mechanism 72 transmits the positive rotational power of the drive motor 71 via the feed side gear train 77 and the discharge side gear train 78, the winding drive shaft 23, and the winding shaft. This is transmitted to the drive shaft 24 and the discharge drive roller 61. As a result, the platen drive shaft 23, the take-up drive shaft 24, and the discharge drive roller 61 are driven to rotate. On the other hand, as shown in FIG. 6B, the reverse rotation power of the drive motor 71 is transmitted to the discharge drive roller 61 via the discharge side gear train 78 while cutting off the power to the feed side gear train 77. Thus, the discharge drive roller 61 is rotationally driven without rotationally driving the platen drive shaft 23 and the winding drive shaft 24.

  Next, the tape processing operation by the tape printer 1 will be described with reference to FIG. First, the control unit drives the drive motor 71 to drive the print head 21 while feeding the tape, and performs a printing process on the printing tape T being sent (see FIG. 7B). . At the time of tape feeding, the drive motor 71 is driven to rotate forward. Due to the forward rotation drive of the drive motor 71, the clutch mechanism 76 is operated, and the first planetary gear 103 is moved to the feed side connection position P1 and connected to the input side of the feed side gear train 77. On the other hand, the second planetary gear 104 moves to the second discharge side connection position P2 and is connected to the input side of the discharge side gear train 78. As a result, the positive rotational power of the drive motor 71 is transmitted to the platen drive shaft 23, the take-up drive shaft 24, and the discharge drive roller 61 via the clutch mechanism 76, the feed-side gear train 77, and the discharge-side gear train 78. The platen roller 35, the ribbon take-up reel 36, and the discharge driving roller 61 are rotationally driven in conjunction (synchronized). Thereby, the printing tape T is rotationally fed by the platen roller 35. At this time, when the leading end of the printing tape T reaches the nip point of the tape discharge mechanism 12, it is drawn into the rotated discharge drive roller 61 and discharge driven roller 63, and is nipped and rotated.

  When the printing process is completed, the drive motor 71 is driven to feed the tape, and the cutting position of the printing tape T is caused to face the full cutter 41 (see FIG. 7C). And after stopping the drive motor 71, the cutter motor 43 is driven and the full cutter 41 is cut | disconnected (refer FIG.7 (d)). That is, the printed portion is cut by the cutting operation (full cut) of the full cutter 41.

  When the cutting process is completed, the drive motor 71 is driven, and the cut-off portion (tape piece) of the cut print tape T is discharged out of the apparatus (see FIG. 7E). The drive motor 71 is driven to rotate in the reverse direction at the time of discharging the separation portion. Due to the reverse rotation drive of the drive motor 71, the clutch mechanism 76 is operated, and the first planetary gear 103 is moved to the first discharge side connection position P3 and connected to the input side of the discharge side gear train 78. On the other hand, the second planetary gear 104 moves to the non-connection position P4 and is in a disconnected state with respect to the feed side gear train 77 and the discharge side gear train 78. As a result, the reverse rotation power of the drive motor 71 is transmitted to the discharge drive roller 61 via the clutch mechanism 76 and the discharge side gear train 78, and the discharge drive roller 61 is rotationally driven. At this time, the platen drive shaft 23 (platen roller 35) and the take-up drive shaft 24 (ribbon take-up reel 36) are in a stopped state.

  By the rotational drive of the discharge drive roller 61, the cut-off portion of the printing tape T is rotated and fed by the discharge drive roller 61 and the discharge driven roller 63, and the cut-off portion is discharged from the tape discharge port 17 to the outside of the apparatus. At this time, since the rotational speed of the discharge-side first input gear 93 is increased as compared with the time of tape feeding in which power is input via the relay gear 92, the rotational speed of the discharge drive roller 61 is increased (high speed), The detached portion of the printing tape T is discharged with great force. This completes the tape processing operation.

  According to the above configuration, before the cutting operation (at the time of tape feeding), the tape discharging mechanism 12 is driven in conjunction with the feeding means 23 and 35, so that the printing tape T is jammed in the tape discharging mechanism 12. Can be prevented. On the other hand, since the tape discharging mechanism 12 is driven without driving the feeding means 23 and 35 after the cutting operation (when the separating part is discharged), the separating part of the printing tape T without unnecessary tape feeding. (Tape piece) can be suitably discharged. In this way, not only the feeding means 23 and 35 and the tape discharging mechanism 12 are driven in conjunction with each other, but also after the cutting operation of the tape cutting mechanism 11, only the tape discharging mechanism 12 is driven, so that the printing tape T The printing tape T can be suitably discharged while preventing jamming.

  In addition, by using the power transmission mechanism 72 having the clutch mechanism 76, the feeding means 23, 35 before the cutting operation can be provided without providing separate driving sources for the feeding means 23, 35 and the tape discharging mechanism 12. In addition, the tape discharge mechanism 12 can be driven in conjunction with it, and only the tape discharge mechanism 12 can be driven after the cutting operation. That is, the feeding means 23 and 35 and the tape discharging mechanism 12 can be used as a motor. Further, the driving of the feeding means 23 and 35 and the driving of the tape discharging mechanism 12 can be easily linked.

  Furthermore, the clutch mechanism 76 can have a simple configuration by using a mechanism applying a planetary gear mechanism as the clutch mechanism 76.

  Still further, by adopting a configuration in which the positive rotational power of the drive motor 71 is input to the discharge-side first input gear 93 via the discharge-side second input gear 91, the drive motor 71 can be driven at the time of forward rotation. Since the rotation direction of the discharge-side first input gear 93 is the same during reverse rotation of the motor 71, transmission of forward and reverse rotation power can be shared at the time of the discharge-side first input gear 93. The discharge-side gear train 78 can be configured simply.

  Further, since the relay gear 92 is provided, the positive rotational power of the drive motor 71 is input from the discharge-side second input gear 91 to the discharge-side first input gear 93 via the relay gear 92. The number of rotations of the discharge-side first input gear 93 at the time of reverse rotation driving (at the time of discharging the separated portion) can be made larger than that at the time of forward driving of the drive motor 71 (at the time of tape feeding). As a result, when discharging the separated portion, the tape discharging mechanism 12 can be driven at a higher speed than when feeding the tape, and the disconnected portion can be discharged quickly (or vigorously).

  In the present embodiment, using the relay gear 92, the rotational speed of the discharge-side first input gear 93 when the drive motor 71 is driven in reverse rotation (when the cut-off portion is discharged) is determined as the forward rotation drive of the drive motor 71. Although it was the structure which increases more than the time (at the time of tape feeding), the structure which controls the drive motor 71 by a control part and performs this may be sufficient.

  Further, the rotational speed of the discharge-side first input gear 93 when the drive motor 71 is driven in reverse rotation (when the cut-off portion is discharged) is set so that the rotation speed of the drive motor 71 is driven (when tape is fed) so that the cut-off portion does not scatter. ) Or less than this.

  Further, in the present embodiment, the single drive motor 71 is configured to be shared by the feeding means 23 and 35 and the tape discharging mechanism 12, but the feeding means 23 and 35 and the tape discharging mechanism 12 are separately provided. The drive motor 71 (drive source) may be included. In this case, each drive motor 71 is controlled by the control unit, and before the cutting operation by the full cutter 41, the feeding means 23 and 35 and the tape discharge mechanism 12 are driven in conjunction with each other, and after the cutting operation by the full cutter 41, The tape discharge mechanism 12 is driven without driving the feeding means 23 and 35.

  Furthermore, in the present embodiment, the present invention is applied to the tape printer 1. However, the present invention is not limited to this as long as the tape feeder of the present invention is applied. For example, the present invention may be applied to a tape stamping apparatus having a stamping head that stamps braille on a stamping tape (tape-shaped member).
