It comprises a tape cartridge 4 containing a printing tape T1 and a laminating tape T2, and an ink cartridge 5 filled with four colors of ink. The tape cartridge 4 and the ink cartridge 5 are detachably attached to the apparatus main body 2. Have been.

Various keys 3a are arranged on the upper surface of the keyboard 3 and constitute input means of the tape printer 1. In this case, the keyboard 3 is attached to the apparatus main body 2 so that the keyboard 3 can be turned upside down. When the tape printing apparatus 1 is used, the keyboard 3 is pulled down. 3 is caused.

The apparatus main body 2 has an outer shell formed by an apparatus case 6, and an opening / closing lid 7 for attaching and detaching the tape cartridge 4 and the ink cartridge 5 is widely provided at an upper portion of the apparatus case 6. A small window 9 is formed in the front right part of the opening / closing lid 7 corresponding to the liquid crystal display unit 8 built in the apparatus main body 2. Further, a slit-shaped tape discharge port 10 for discharging the laminated printing tape T1 to the outside is formed on a side surface of the device case 6.

Inside the device case 6, there is a printing tape T1.
And a tape feeder 11 for sending the laminate tape T2 and attaching the laminate tape T2 to the print tape T1, a printing device 12 for performing color printing on the print tape T1 by an inkjet method,
A cutting device 13 for cutting the device 1 and a circuit board 14 for controlling these devices and performing information processing are mounted. Further, an ejection mechanism 15 for setting the tape cartridge 4 at a position accessible by these devices is provided inside the device case 6 (see FIG. 2).

Each of these devices is controlled by a control circuit incorporated in the circuit board 14 to operate in association with each other. More specifically, when the tape feeding device 11 is driven, the printing tape T1 is fed out from the tape cartridge 4, and the printing device 12 facing the upper side of the intermediate portion of the tape cartridge 4 performs printing based on the key input. Is performed. While the printing is being performed, the printing tape T1 is further sent to the other side, and the laminating tape T2 drawn out from the tape cartridge 4 is continuously adhered to the printing tape T1. Printing tape T1 with laminated tape T2 adhered to the printed part
Is further fed out from the tape discharge port 10 by the printing tape feeding device 11, but when the trailing end of the printed portion in consideration of the margin reaches the cutter position, the printing tape feeding device 11 stops and the cutting device 13 operates to cut the print tape T1 (and the laminate tape T2). In this way, a laminated label on which desired characters and the like are printed is created.

The printing apparatus 12 includes a carriage guide shaft 31 whose left and right ends (front and rear in FIG. 1) are supported by a frame (not shown), a carriage 32 slidably attached to the carriage guide shaft 31, By doing so, a timing belt (not shown) that reciprocates the carriage 32 in the left-right direction and a carriage motor (not shown) that causes the timing belt to travel forward and backward are provided. Also, the carriage 32
, A print head 33 is attached to a lower part thereof, and a cartridge holder 34 for mounting the ink cartridge 5 is attached to an upper part thereof. In this case, the print head 33 is mounted downward, and the ink cartridge 5 is mounted on the cartridge holder 34 downward. When the ink cartridge 5 is mounted, the ink tanks 5a of the respective colors of the ink cartridge 5 communicate with the print head 33, so that ink can be supplied to the print head 33. The ink tank 5a is filled with ink of each color of yellow, cyan, magenta, and black (black).

The tape feeding device 11 has a printing tape side feeding mechanism 11a and a laminate tape side feeding mechanism 11b with the printing device 12 interposed therebetween in the feeding direction. The print tape side feed mechanism 11a includes a feed roller 41 having a feed driven roller 42 and a feed drive roller 43 arranged vertically.
And a feed motor (not shown) for driving the feed drive roller 43 to rotate. The feed drive roller 43 is used for the apparatus main body 2
The feed driven roller 42 is provided on the tape cartridge 4. When the tape cartridge 4 is mounted on the apparatus main body 2, the feed driven roller 42 presses the print tape T1 so as to sandwich the print tape T1 between the feed drive roller 43 and the feed driven roller 42. By rotating the feed motor in this state, the print tape T1 sandwiched between the feed driven roller 42 and the feed drive roller 43 is sent to the front. Note that the feeding of the printing tape T1 and the reciprocation of the print head 33 correspond to the relationship between the main scanning direction and the sub-scanning direction in the printing technology. Therefore, the feed motor and the carriage motor are driven in conjunction with each other.

The laminating tape-side feeding mechanism 11b includes a laminating roller 44 having a lami driven roller 45 and a lami driving roller 46 arranged vertically, and a lami driving roller 4
And a laminating motor (not shown) for rotating the motor 6. The laminating motor and the above-mentioned feed motor are the same, and the power is branched via a reduction gear train (not shown) to transmit the power to the feed roller 41 and the laminating roller 44, respectively. The lami driving roller 46 is provided on the apparatus main body 2, and the lami driven roller 45 is provided on the tape cartridge 4. When the tape cartridge 4 is mounted on the apparatus main body 2, the lami driven roller 45 presses the print tape T <b> 1 and the laminate tape T <b> 2 so as to sandwich the print tape T <b> 1 and the laminate tape T <b> 2 between them. When the laminating motor rotates in this state, the printing tape T1 and the laminating tape T2 sandwiched between the lami driven roller 45 and the lami driving roller 46 are sent to the front while being adhered.

In this case, it is preferable that the lami driven roller 45 is a metal or resin roller and the lami driving roller 46 is a roller in which rubber is wound around a metal or resin roller. In this way, the laminating tape T2 can be stuck to the printing tape T1 with a uniform holding force, and the cost of the consumable lami driven roller 45 on the tape cartridge 4 side can be reduced. Therefore, the cost of the tape cartridge 4 can be reduced.

The printing tape T1 can be fed horizontally between the feed roller 41 and the laminating roller 44.
The feed roller 41 and the laminating roller 44 are disposed on the same horizontal plane. The rollers 41 and 44 are configured such that the peripheral speed of the laminating roller 44 is slightly higher than the peripheral speed of the feed roller 41.
1 is made to have tension.

The cutting mechanism 13 has a cutter 51 and a cutter motor (not shown) for operating the cutter 51 for cutting. When the feed motor (laminating motor) steps the printing tape T1 by a predetermined distance after printing is completed, both motors stop, and at the same time, the cutter motor is driven to cut the printing tape T1. Will be The cutting operation of the cutter 51 may be performed by a key operation.

Here, the ejecting mechanism for appropriately mounting the printing tape T1 and the laminating tape T2 which are accessed by these devices, the tape cartridge 4 in which these are accommodated, and the tape cartridge 4 in the apparatus main body 2 properly. 15 will be described in detail.

The printing tape (tape body) T1 is composed of a base tape, an adhesive layer applied to the back surface of the base tape, and a release paper tape attached to the adhesive layer. It is made of a material that can sufficiently absorb ink, such as paper having a coat layer or a film having a coat layer. The adhesive layer is for attaching a printing tape as a label to an object to be attached such as a file, and the release paper tape is for preventing dust and the like from adhering to the adhesive layer. . On the other hand, the laminate tape (tape body) T2 is composed of a base tape and an adhesive layer applied to the back surface of the base tape.
It is composed of a transparent film having a thickness of about 16 to 38 μm.

The printing tape T1 and the laminating tape T2 adhered thereto are formed to have substantially the same width.
It is stuck so that the side edges are aligned. Actually, the laminating tape T2 is formed to be slightly (about 0.3 mm) narrower than the printing tape T1, so that a slight lateral displacement of the laminating tape T2 at the time of sticking can be absorbed. That is, the width of the laminate tape T2 is narrowed by 0.15 mm on both sides in the width direction with respect to the print tape T1, and the laminate tape T2 does not protrude from the print tape T1 with respect to a shift amount assumed due to a manufacturing error or the like. Like that.

The total length of the printing tape T1 is formed to be somewhat shorter than the total length of the laminating tape T2 mounted on the tape cartridge 4.
Is used before the printing tape T1 is used. This prevents printing on the printing tape T1 even though the laminating tape T2 cannot be stuck. It is preferable to notify the user immediately before the use of the printing tape T1 that the remaining amount of the printing tape T1 is small. For example, a through hole (a black portion may be formed) is formed at the rear end of the printing tape T1, and the through hole is detected by an optical sensor or the like, and an alarm is issued.

On the other hand, as the printing tape T1 and the laminating tape T2, various types (about 10 types) having a tape width of about 4.5 mm to 96 mm are prepared, and these various tapes T1 and T2 are respectively tape cartridges. 4
Provided in a housed state. More specifically, the tape cartridge 4 is of a type capable of mounting the printing tape T1 and the laminating tape T2,
There is a type in which only one can be mounted (see FIGS. 3 and 7). In addition, the tape cartridges 4 roughly classified into these two types have different widths “large”, “medium”,
Three types of "small" are prepared, one with different width
For the 0 types of tapes, several types of narrow width are "small", several types of intermediate width are "medium", and several types of wide width are "large".
, Respectively. The printing tape T1 is also prepared with a material different in material or a material having a ground color other than white. At least several tens of types of tapes T1 and T2 can be used, including those used in the future. ing.

Next, the tape cartridges 4 which are roughly classified into two types depending on whether or not they have a laminated tape will be described by taking the above-mentioned "large" having the largest size as an example.
The tape cartridge 4a shown in FIGS. 3 and 4 is of a type in which the printing tape T1 and the laminating tape T2 are mounted, and the main housing portion 61 that houses the printing tape T1.
And a sub-accommodating portion 62 accommodating the laminating tape T2 in the middle.
The print head 33 of the printing apparatus 12 faces 3. The cartridge case 64 constituting each of these components is formed by a main body case 65, a main case cover 66 on the main housing portion 61 side, and a sub case cover 67 on the sub housing portion 62 side. The main case lid 66 and the sub-case lid 67 may be configured to be openable on the user side, and the printing tape T1 and the laminate tape T2 may be exchangeable on the user side. In such a case, in order to prevent the printing tape T1 and the laminating tape T2 from being erroneously attached, it is preferable that the diameter of the tape shaft 68 and the diameter of the laminating tape shaft 69 described later be different.

The main storage portion 61 stores a printing tape T1 wound in a roll shape, and the sub-storage portion 62 similarly stores a laminate tape T2 wound in a roll shape.
The printing tape T1 is mounted on a tape shaft 68, and the tape shaft 6
8 and is rotatably attached to the cartridge case 64. Similarly, the laminating tape T2 is mounted on a laminating tape shaft 69, and is rotatably attached to the cartridge case 64 via the laminating tape shaft 69.

As shown in FIG. 5, the printing tape T1 includes a tape body T1a and a tape core T1b, and the tape body T1a is wound around the tape core T1b in a roll shape. The length of the tape core T1b in the axial direction is slightly longer than the length of the tape body T1a in the axial direction, that is, the tape width.
The tape body T1a does not come into contact with the tape. Also, a keyway T1c is provided on the inner peripheral surface of the tape core T1b.
When the printing tape T1 is mounted on the tape shaft 68, the key groove T1c
8 key portion 74.

As shown in FIG. 6, the tape shaft 68 includes a shaft main body 70 on which the printing tape T1 is rotatably mounted, a flange 71 for regulating the axial movement of the printing tape T1 mounted on the shaft main body 70, and The retaining hook 72 is integrally formed. The flange 71 includes a disk portion 73, a key portion 74 provided inside the disk portion 73 in the axial direction, and a disk portion 73.
And a rotation regulating portion 75 provided on the outside in the axial direction. The key portion 74 is extended from the disk portion 73 and the shaft main body 70, and engages with the key groove T1c of the printing tape T1 mounted on the shaft main body 70 to act as a stop for the printing tape T1. The rotation restricting portion 75 has a plurality of protrusions 75a on the outer peripheral surface and is formed in a star shape as a whole. When the tape cartridge 4 a is detached from the apparatus main body 2, an engagement piece 96 of a feed pressing lever 91, which will be described later, is engaged with the rotation regulating portion 75, and
When transporting or storing a, the printing tape T1 does not rotate. Conversely, when the tape cartridge 4a is mounted on the apparatus main body 2, the rotation restricting portion 75
, The engaging piece 96 is released, and the printing tape T1 can be fed out.

The shaft main body 70 is formed in a pipe shape, and is rotatably supported at both outer ends on both inner sides of the cartridge case 64. The retaining hook 72 is formed by cutting a part of the shaft main body 70 that is long in the axial direction and has a “U” -shaped notch so as to have a spring property. A regulating protrusion 7 protruding from the outer peripheral surface of the shaft main body 70 is provided at the tip of the retaining hook 72.
2a are formed, and the regulating protrusion 72a is formed in a torsion shape with a downward slope. When the printing tape T1 is inserted from the outer end of the shaft body 70 toward the flange 71, the tape core T1b of the printing tape T1 rides on the regulating protrusion 72a and is inserted by pushing it. When the printing tape T1 is inserted to a position where it abuts on the flange 71, the regulating protrusion 72a comes off from the end of the tape core T1b, and the regulating protrusion 72a returns to the original state.

That is, when the printing tape T1 is completely inserted into the shaft main body 70, the key groove T1c of the tape core T1b is engaged with the key portion 74 of the flange 71, and the rotation of the printing tape T1 with respect to the tape shaft 68 is restricted. In addition, tape core T
1b is located between the flange 71 and the regulating protrusion 72a,
The printing tape T1 is attached to the tape shaft 68 in a state where the printing tape T1 does not come off. In this case, the length of the tape core T1b in the axial direction is slightly shorter than the distance between the flange 71 and the regulating protrusion 72a, and the printing tape T1 has a predetermined clearance with respect to the tape shaft 68. It is mounted so that it can move slightly in the axial direction. Thereby, the printing tape T1 fed out from the state wound in a roll shape,
Following the regulation of the width and position of the tape guide 106 to be described later, the tape guide 106 slightly moves in the left-right direction (axial direction).

As described above, the printing tape T1 fed out
However, since it is configured to slightly move in the axial direction following the tape guide 106, even if the printing tape T1 has a winding deviation in manufacturing, an appropriate width direction position toward the feed roller 41 can be achieved. , And can be fed out. Therefore, the printing tape T1 fed out
The printing tape T1 can be smoothly and accurately sent out without applying excessive force to the printing tape T1.

Similarly, as shown in FIG. 7, the laminated tape T2 includes a tape body T2a and a tape core T2b, and the tape body T2a is wound around the tape core T2b in a roll shape. The length of the tape core T2b in the axial direction is slightly longer than the length of the tape body T2a in the axial direction, that is, the tape width, so that the tape body T2a does not contact the flange 77 of the laminating tape shaft 69 described later. ing. Further, a pair of key grooves T2c are formed on the inner peripheral surface of the tape core T2b at opposing positions. When the laminated tape T2 is mounted on the lami tape shaft 69, the key grooves T2c are moved to a lami tape shaft 6 described later.
9 is engaged with the key portion 81.

As shown in FIG. 8, the laminating tape shaft 69 is
Shaft body 7 on which laminating tape T2 is rotatably mounted
6, and a flange 77 and a retaining hook 78 for restricting the axial movement of the laminated tape T2 mounted on the shaft body 76 are integrally formed. A braking spring 79 is wound around the outer end of the shaft body 76 on the flange 77 side. The flange 77 includes a disk portion 80 and a key portion 81 provided inside the disk portion 80 in the axial direction. The key portion 81 extends from the disk portion 80 and the shaft main body 76, and engages with the key groove T2c of the laminate tape T2 mounted on the shaft main body 76 to act as a rotation stop for the laminate tape T2.

The shaft main body 76 is formed in a pipe shape, and is rotatably supported at both outer ends on both inner sides of the cartridge case 64. The retaining hook 78 is formed in the same manner as the retaining hook 72 of the tape shaft 68 by forming a cutout in a part of the shaft main body 76, and has a regulating projection 78a at its tip. That is, the laminate tape T
2 is completely inserted into the shaft body 76, the tape core T2b
Key groove T2c engages with the key portion 81 of the flange 77,
The rotation of the laminating tape T2 is regulated with respect to the laminating tape shaft 69, and the tape core T2b is positioned between the flange 77 and the regulating protrusion 78a. Also in this case, the length of the tape core T2b in the axial direction is slightly shorter than the distance between the flange 77 and the regulating protrusion 78a. It is mounted so that it can move slightly in the axial direction with a clearance.

Also in this case, as in the case of the printing tape T1, since the laminated tape T2 to be fed is configured to move slightly in the axial direction, even if the laminated tape T2 has a winding deviation in manufacturing, It can be fed out while maintaining an appropriate position in the width direction toward the laminating roller 44. Therefore, no unreasonable force is applied to the fed laminate tape T2,
Problems such as wrinkles can be prevented. In addition, since the laminate tape T2 can be sent out with high accuracy, the laminate tape T2 can be accurately attached to the print tape T1.

On the other hand, the brake spring 7 wound around the shaft body 76
Numeral 9 is formed in a coil shape and wound around the shaft main body 76 lightly with one end fixed to the cartridge case 64. When the laminate tape T2 is fed, the rotation of the laminating tape shaft 69 is braked by friction between the shaft main body 76 and the braking spring 79. Thereby, at the time of feeding, the laminate tape T2 can be attached to the printing tape T1 in a stretched state, and at the time of non-feeding, the laminating tape T2 can be prevented from sagging. In particular, in this braking structure, since a force that pushes the shaft main body 76 in one direction is not applied, inclination and displacement of the shaft can be prevented. In addition, laminating tape T
Sticking to the inner surface or the like of the cartridge case 64 due to the slack can be effectively prevented. It is preferable that the winding direction of the braking spring 79 is a direction in which the braking spring 79 is wound by the rotation of the laminating tape shaft 69 when the laminate tape T2 is fed.

The printing tape T1 and the laminating tape T2 configured as described above are fed to the feed driven roller 42 described above.
And a feed roller 41 comprising a feed drive roller 43 and
The sheet is sent out by a laminating roller 45 composed of a lami driven roller 45 and a lami driving roller 46, and is adhered to each other by the laminating roller 44. In this embodiment, a freely driven feed driven roller 42 and a laminated driven roller 45 are mounted on the tape cartridge 4a. In the following description of the area around the tape cartridge 4, unless the direction can be defined by “tip” and “tail end”, the sub-housing section side is “front”, the main housing section side is “rear”, and the width direction is The explanation will proceed with “left” and “right”.

As shown in FIGS. 3 and 4, the feed driven roller 42 and the lami driven roller 45 are arranged to face each other with the connecting portion 63 of the tape cartridge 4a interposed therebetween. Feed driven roller 42 and lami driven roller 45
Are rotatably supported on both inner sides of the cartridge case 64 by their support shafts 42a and 45a and movably in the vertical direction. A pair of left and right feed pressing levers 91 for pressing the feed driven roller 42 toward the feed driving roller 43 is incorporated in the main housing 61, and a lami driven roller 91 is provided in the sub housing 62. A pair of left and right lami pressing levers 92 for pressing the 45 toward the lami driving roller 46 are incorporated.

Each of the feed pressing levers 91 comes into contact with the support shaft 42a of the feed driven roller 42 from above at the leading end 93, and swings on the cartridge case 64 with a shaft 94 formed at a position near the leading end of the intermediate portion. It is freely supported. At the tail end of the feed pressing lever 91, a push-up piece 95 extending downward and abutting on a feed urging arm 134 of the eject mechanism 15 described later, and the tape shaft 68 extending upward and
And an engagement piece 96 that engages with the rotation restricting portion 75, and moves the feed pressing lever 91 itself backward to separate the leading end 93 from the support shaft 42a of the feed driven roller 42. A grip piece 97 is formed. Further, a spring portion 98 extending obliquely downward is formed at an intermediate portion of the feed pressing lever 91, and the tip of the spring portion 98 abuts on the bottom surface of the cartridge case 64.
The spring portion 98 urges the feed pressing lever 91 itself around the shaft portion 94 on the tip side downward and on the tail end side upward.

In this case, the spring portion 98 urges the entire feed pressing lever 91 upward.
It contacts a substantially semicircular bearing portion formed in the cartridge case 64 from below, and the shaft portion 94 is swingably engaged with the bearing portion so as to be pressed from above.
The relationship and function between the substantially semicircular bearing portion and the gripping piece 97 will be described later in detail.

In the tape cartridge 4a in the non-mounted state, the feed pressing lever 91 is moved upward by the action of the spring portion 98 so that the engagement piece 96 moves upward and the rotation restricting portion 7 of the tape shaft 68 is rotated.
5 and regulates the rotation of the printing tape T1, while the leading end 93 moves down to move the feed driven roller 42 to the lower end position. The feed follower roller 42 that has moved to the lower end position sandwiches the print tape T1 between itself and the cartridge case 64. That is, in this non-attached state, the rotation of the printing tape T <b> 1 is restricted by the engagement piece 96, and the feeding of the printing tape T <b> 1 is restricted by the feed driven roller 42.

On the other hand, when the tape cartridge 4a is mounted on the apparatus main body 2, the feed driven roller 42 comes into contact with the feed drive roller 43 of the apparatus main body 2, and the feed driven roller 42 is slightly pushed up. Thereby, the feed driven roller 42
Is released from the printing tape T1. Also,
The leading end 93 of the feed pressing lever 91 moves up and the tail end moves down, and the engaging piece 96 separates from the rotation restricting portion 75, so that the printing tape T1 can be fed out. At the same time, the push-up piece 95 abuts against the feed urging arm 134 of the eject mechanism 15, and the feed urging arm 134 constantly rolls the feed driven roller 42 through the feed pressing lever 91 to the feed drive roller 43. Press

As described above, by incorporating the feed driven roller 42 into the tape cartridge 4a, the printing tape T1
Can be automatically carried out by using the tape cartridge 4a mounted on the apparatus main body 2 by using the tape cartridge 4a. That is, the feed driven roller 42 is connected to the apparatus main body 2.
The moving mechanism and the like in the case of being incorporated in the device can be omitted and the structure can be simplified. Further, since the length of the feed driven roller 42 in the axial direction can be made to correspond to the tape width of the print tape T1, the pressing force of the feed driven roller 42 can be uniformly applied in the width direction of the print tape T1. The printing tape T1 can be sent stably. Further, since the feed pressing lever 91 is provided so as to be capable of swinging like a seesaw over the entire length of the main housing portion 61, the spring force from the feed urging arm 134 is used to make use of the leverage principle to feed the driven roller. 42. For this reason, a large spring force can be applied while the spring constant of the spring (compression spring) on the feed urging arm 134 side is reduced, and the feed driven roller 42 can be pressed with a stable force.
