TECHNICAL FIELD OF THE INVENTION
The present invention relates to a tape cassette in which at least a tape spool around which a print-receiving tape is wound is arranged in a cassette case, and which is used in a tape printing apparatus to create a character-attached tape on which characters and the like are printed on the print-receiving tape The present invention relates to a tape cassette provided with a positioning portion which is provided at a predetermined position of the tape cassette and engages with a positioning member provided on the tape printing apparatus main body side.
[0002]
[Prior art]
Conventionally, as disclosed in Japanese Patent Application Laid-Open No. 4-133756, for example, when a cassette is mounted on a tape printing apparatus main body, a tape feeding roller or a ribbon take-up spool is provided on the tape printing apparatus main body. There is a known type in which a cassette is fixed to a main body of a tape printing apparatus by fitting a drive shaft of a tape feed roller or a drive shaft of a ribbon take-up spool.

[Problems to be solved by the invention]
However, in the above-described prior art, only a tape feed roller drive shaft and a ribbon take-up spool drive shaft provided in the tape printing device main body are provided as members for fixing the cassette to the tape printing device main body. Even when the tape is attached to the main body of the tape printing apparatus, the mounted cassette may be insufficiently fixed and rattling may occur.If printing is performed in such a state, the tape to be printed will be fed properly. There is a problem that the feeding of the print-receiving tape by the tape feed roller becomes unstable without being supplied to the roller. As described above, when the transport of the print-receiving tape becomes unstable, the print-receiving tape is displaced when printing is performed on the print-receiving tape by the print head on the main body side, thereby deteriorating the print quality, or receiving the print-receiving tape from the tape discharge unit of the cassette. The disadvantage is that the printing tape is not discharged to the outside.
[0004]
In some tape printers, a detection switch is provided on the main body side to identify the type of the mounted tape cassette by interacting with the cassette detecting section of the tape cassette. In order to minimize the effect on printing when the unit is lifted upward by the repulsive force of the detection switch on the main unit side, the printing position and the cassette detection unit may be arranged at the farthest position, Even with such a tape printer, there is a problem that the fixed state of the mounted cassette tends to be insufficient due to the repulsive force of the switch terminal.

[0012]
【Example】
Hereinafter, the present invention will be described in detail with reference to the drawings based on an embodiment in which a tape cassette used in a tape printer is embodied. First, a schematic configuration of the tape cassette 1 will be described with reference to FIG. FIG. 1 is a perspective view of the tape cassette 1. The tape cassette 1 has an upper case 2 and a lower case 3.
[0013]
The tape cassette 1 has a support hole 4 for rotatably supporting a tape spool 18 around which a film tape 17 described later is wound, and a ribbon spool 20 for printing characters and the like on the film tape 17 by a thermal head H described later. A support hole 5 that supports a ribbon take-up spool 21 that pulls out and winds an ink ribbon 19 from the printer, and a support that rotatably supports a tape spool 23 in which release paper of a double-sided adhesive tape 22 described later is wound outward. A hole 7 is formed.
[0014]
Although FIG. 1 shows only the support holes 4, 5, and 7 formed in the upper case 2, the lower case 3 is similarly supported facing the support holes of the upper case 2. Holes 4, 5, and 7 are formed.
[0015]
In addition, the front side (lower side in FIG. 1) of the tape cassette 1 guides the film tape 17 pulled out from the tape spool 18 and the ink ribbon 19 drawn out from the ribbon spool 20, and sends the book through the opening 8A. An arm portion 8 (detailed configuration will be described later) constituting a guide portion of the invention is provided, and a head mounting on which a thermal head H (described later) of a tape printing apparatus is mounted behind the arm portion 8. A part 9 is provided. Further, a first fitting portion 10 is formed on a wall portion 9A of the head mounting portion 9 facing the arm portion 8 and extends toward the rear of the tape cassette 1, and a left side wall of the head mounting portion 9 has a first fitting portion. A second fitting portion 11 is formed to enter in a direction orthogonal to the one fitting portion 10 (a direction along the wall portion 9A).
The first fitting portion 10 and the second fitting portion 11 are fitted to two projecting portions 45 and 46 formed on a head holder 44 that supports the thermal head H, as described later. This is to ensure that the thermal head H is mounted on the head mounting portion 9 without interfering with the ink ribbons 19 and the film tape 17.
[0016]
Further, a tape feed roller 12 is rotatably supported by a support hole 13 on the downstream side of the head mounting portion 9 with respect to the running direction of each of the ink ribbon 19 and the film tape 17, and the tape feed roller 12 faces the tape feed roller 12. The film head 17 is pulled out from the tape spool 18 and the double-sided adhesive tape 22 is drawn out from the tape spool 23 in cooperation with a pressure roller 49 (see FIG. 15) pressed against the tape feed roller 12 from the side where the heat is applied. Thus, the film tape 17 on which characters and the like are printed via the ink ribbon 19 and the double-sided adhesive tape 22 are mutually bonded. A pair of upper and lower regulating members 14 and 15 are provided in the vicinity of the tape feed roller 12, and each of the regulating members 14 and 15 is a film on which characters or the like are printed on the downstream side of the thermal head H. The tape 17 is regulated and guided in the width direction, and is used for properly bonding the film tape 17 and the double-sided adhesive tape 22 without causing a positional shift. The detailed configurations of the tape feed roller 12 and the regulating members 14 and 15 will be described later.
[0017]
As shown in FIG. 1 and FIG. 2 to be described later, a cassette detecting section 16 is formed at the corner at the right rear edge position of the tape cassette 1 and farthest from the head mounting section 9. ing. The head mounting section 9 is located near another corner on the diagonal of the corner near the cassette detecting section. The cassette detector 16 detects a type of the tape cassette 1 (for example, the type of the tape cassette 1 is specified by the width of each film tape 17, the color of ink applied to the ink ribbon 19, and the like). A plurality of switch holes 16A are formed in a pattern. The formation pattern of the switch holes 16A is different according to the type of each tape cassette 1, and each switch hole 16A is provided with a plurality of detection switches 81 (see FIGS. 21 and 23) provided on the tape printing apparatus side. ) Is detected based on the combination of ON and OFF. This configuration will be described later.
[0018]
Incidentally, the tape cassette 1 has a tape printing apparatus in which a cassette mounting portion X (see FIGS. 13 and 20) is provided on the upper surface and a tape printing device in which the cassette mounting portion X is provided on the lower surface. For a tape printer in which the cassette mounting portion X is provided on the upper surface, the cassette mounting portion X is mounted on the cassette mounting portion X from the lower case 3 side (referred to as a front loading method). Further, for a tape printer in which the cassette mounting portion X is provided on the lower surface, the tape mounting device is mounted on the cassette mounting portion X from the upper case 2 side (hereinafter, referred to as a bottom loading system). As described above, in order to adapt to any of the front loading method and the bottom loading method, the tape cassette 1 according to the present embodiment has various characteristic configurations as described below. The characteristic configuration will be described sequentially.
[0019]
Next, the internal configuration of the tape cassette 1 will be described with reference to FIGS.
First, an outline of the internal configuration of the tape cassette 1 will be described with reference to FIG. FIG. 2 is a plan view of the lower case 3 with the upper case 2 removed, and a tape spool 18 around which a transparent film tape 17 is wound at the rear part (upper part in FIG. It is arranged so as to be rotatable through. A ribbon spool 20 around which an ink ribbon 19 is wound is disposed rotatably at a front portion (a lower portion in FIG. 2) of the lower case 3. Further, the ink ribbon 19 is pulled out from the ribbon spool 20, and characters and the like are drawn. A ribbon take-up spool 21 for winding up the ink ribbon 19 consumed in the printing of the print medium is rotatably disposed between the tape spool 18 and the ribbon spool 20 via the support hole 5.
[0020]
As described above, the film tape 17 is pulled out from the tape spool 18 by the cooperation of the tape feed roller 12 and the pressure roller 49 (provided on the tape printing device side), and the head is mounted through the opening 8A of the arm portion 8. After passing through the front side (lower side in FIG. 2) of the unit 9, the tape 9 is adhered to the double-sided adhesive tape 22 and discharged from the tape discharge unit 24 to the outside of the tape cassette 1. The ink ribbon 19 is pulled out of the ribbon spool 20 via the ribbon take-up spool 21, passes through the opening 8 </ b> A of the arm 8, and passes through the front side (the lower side in FIG. 2) of the head mounting section 9, and then controls each of the regulating members It is wound around the ribbon take-up spool 21 through a guide hole 25A of a guide portion 25 formed inside of 14 and 15. A clutch spring 26 is attached to a lower portion of the ribbon take-up spool 21. The clutch spring 26 prevents the ribbon take-up spool 21 from rotating in the reverse direction to loosen the ink ribbon 17 taken up. is there.
[0021]
Here, the ribbon width of the ink ribbon 19 is configured to be wider than the tape width of the film tape 17, as shown in FIG. This ensures that the film tape 17 and the ink ribbon 19 are separated from each other on the upstream side of each of the regulating members 14 and 15, and that the ink on the downstream side of each of the regulating members 14 and 15 is This is to prevent the ribbon 19 from being pulled out. That is, the width (height) W set between the regulating members 14 and 15 is the same as the tape width of the film tape 17, and is therefore set smaller than the ribbon width of the ink ribbon 19. Will be. Thereby, when the ink ribbon 19 is guided to travel from the opening 8A of the arm portion 8 through the guide hole 25A of the guide portion 25 according to the film tape 17, the width W between each of the regulating members 14 and 15 is reduced. Since the width is smaller than the width, it is prevented from entering between the restriction portions 14 and 15. As a result, even if the ink ribbon 19 is stuck to the film tape 17 and tries to travel with the film tape 17, the ink ribbon 19 Can be reliably prevented from traveling to the downstream side of each of the regulating members 14 and 15. Therefore, on the downstream side of each of the regulating members 14 and 15, the ink ribbon 19 is not pulled out more than necessary with the running of the film tape 17 at all.
[0022]
Thereby, even when the ink ribbon 19 is slightly loosened, the ink ribbon 19 stuck to the film tape 17 is pulled out more than necessary due to the drawing out of the film tape 17 and Adhesion can reliably prevent the ink ribbon 19 from jamming in the tape cassette 1 and making the tape cassette 1 unusable.
[0023]
Also, by making the ribbon width of the ink ribbon 19 larger than the tape width of the film tape 17, the ribbon width of the ink ribbon 19 naturally becomes larger than the printing width of characters and the like on the film tape 17, thereby increasing the film width. Even when characters and the like are continuously printed using the printing width of the tape 17 to the maximum, the ink ribbon 19 is cut because the unused portion of the ink ribbon 19 remains on both sides of the printing width. This can be prevented. Note that the tape width of the film tape 17 and the tape width of the double-sided adhesive tape 22 are the same because the tapes are adhered to each other to create a tape with characters.
[0024]
Here, a method of attaching the end portions of the film tape 17 and the ink ribbon 19 to the tape spool 18 and the ribbon spool 20, respectively, will be described with reference to FIGS. FIG. 3 is an exploded perspective view schematically showing a method of attaching the end portions of the film tape 17 and the ink ribbon 19 to the tape spool 18 and the ribbon spool 20, and FIG. FIG. 5 is a plan view illustrating a state where the ribbon spool is attached to the ribbon spool.
[0025]
In each of these figures, the ends 17A and 19A of the film tape 17 and the ink ribbon 19 are connected between both ends 27A and 27B of the adhesive tape 27 wound and adhered in a loop around the tape spool 18 and the ribbon spool 20. By being fixed by bonding, they are attached to the tape spool 18 and the ribbon spool 20.
[0026]
In the case where the film tape 17 and the ink ribbon 19 are attached to the tape spool 18 and the ribbon spool 20 in this manner, a force relationship when a pulling force acts on the film tape 17 and the ink ribbon 19 will be described with reference to FIG. explain. At this time, the tape spool 18 and the ribbon spool 20 are rotated in the direction of arrow A.
[0027]
In this state, when a pulling force is applied to the film tape 17 and the ink ribbon 19 in the direction indicated by the arrow B, the pulling force acts as a force for detaching the adhesive tape 27 from the tape spool 18 and the ribbon spool 20. Both ends 27A and 27B of the adhesive tape 27 are separated from the film tape 17 by a force that overcomes the shear resistance of the entire adhesive surface of the adhesive tape 27 with the spools 18 and 20 and a tensile force acting in the directions indicated by arrows C and D. , And acts as a force for peeling the adhesive tape 27 from the spools 18 and 20.
[0028]
At this time, the adhesive tape 27 is adhered to the tape spool 18 and the ribbon spool 20 in a loop shape around the periphery thereof. Therefore, the ends 17A and 19A of the film tape 17 and the ink ribbon 19 are attached to the adhesive tape 27. Is firmly fixed to the tape spool 18 and the ribbon spool 20 via the adhesive tape 27 to such an extent as to sufficiently oppose the force for peeling off the spools 18 and 20 from the tape spool 18 and the ribbon spool 20. It can be reliably prevented from being easily peeled off.
[0029]
Further, the film tape 17 and the ink ribbon 19 may be attached to the tape spool 18 and the ribbon spool 20 by a method as shown in FIGS. FIG. 5 shows an attachment method in which one end 27B of the adhesive tape 27 is configured to be long and the film tape 17 and the ends 17A and 19A of the ink ribbon 19 are adhered to the end 27B. FIG. 6 shows a configuration in which the adhesive tape 27 is composed of two sheets, and when the adhesive tape 27 is wound and adhered to the tape spools 18 and 20, a part of each adhesive tape 27 is overlapped with each other, and the end 27A of each adhesive tape 27 is overlapped. A method for fixing the film tape 17 and the ends 17A and 19A of the ink ribbon 19 between them will be described. FIG. 7 is basically the same as the fixing method of FIG. 6, and shows a fixing method in which a part of each adhesive tape 27 is not overlapped. FIG. 8 shows a method of fixing using a pressure-sensitive adhesive tape 27 in which no adhesive is present in a portion where the tape spool 18 and the ribbon spool 20 are wound and only the end 27A has an adhesive. .
[0030]
Whichever fixing method is used, the ends 17A and 19A of the film tape 17 and the ink ribbon 19 can be firmly fixed to the tape spool 18 and the ribbon spool 20 via the adhesive tape 27.
[0031]
Next, the configuration of the ribbon take-up spool 21 will be described with reference to FIG. FIG. 9 is a sectional view of the ribbon take-up spool 21. The ribbon take-up spool 21 is rotatably supported between the support hole 5 of the upper case 2 and the support hole 5 of the lower case 3. A plurality of engagement ribs 30 are provided on the inner wall of the ribbon take-up spool 21 at a substantially central position L (indicated by a broken line L) in the vertical direction. It is formed symmetrically.
[0032]
Then, as described later, when the tape cassette 1 is set in the cassette mounting portion X of the tape printer, the ribbon winding shaft 65 provided in the cassette mounting portion X is inserted into the ribbon winding spool 21. When the ribbon take-up shaft 65 is inserted into the ribbon take-up spool 21, the plurality of cam members 66 formed around the ribbon take-up shaft 65 are engaged with the respective engagement ribs 30. At this time, since the engaging ribs 30 are formed vertically symmetrical with respect to the center position L, the cam member 66 of the ribbon winding shaft 65 is connected to the engaging ribs in both front loading and bottom loading. 30 can be properly engaged.
[0033]
In addition, the ribbon take-up spool 21 is rotated in the same direction in both front loading and bottom loading (see FIGS. 20 and 22), and each engagement rib 30 is aligned with the rotation direction. When the ribbon take-up spool 21 is mounted on the upper case 2 and the lower case 3 of the tape cassette 1 in a reverse direction, the ribbon take-up spool 21 can rotate normally. Disappears. In order to prevent this, the diameter of the support hole 5 in the upper case 2 is set to be larger than the diameter of the support hole 5 in the lower case 3, and the outer diameter of the upper end 21A of the ribbon take-up spool 21 is adjusted to the lower end 21B. The outer diameter is set larger than the outer diameter, and the upper end 21A is fitted into the support hole 5 of the upper case 2, and the lower end 21B is fitted into the support hole 5 of the lower case 3. By adopting this configuration, the ribbon take-up spool 21 is always mounted on the tape cassette 1 while maintaining the positional relationship shown in FIG. 9, whereby the ribbon take-up spool 21 is erroneously mounted on the tape cassette 1. Can be reliably prevented.
[0034]
Next, a configuration for guiding the film tape 17 and the ink ribbon 19 in the arm section 8 will be described with reference to FIG. FIG. 10 is an exploded perspective view showing the configuration of the arm portion 8. The arm portion 8 of the lower case 3 has an outer wall 8 </ b> B and an inner wall 8 </ b> C which is higher than the outer wall 8 </ b> B and has almost the same height as the ribbon width of the ink ribbon 19. It is composed of A separation wall 31 having the same height as the inner wall 8C is provided between the outer wall 8B and the inner wall 8C. A pair of guide restricting pieces 32, 32 are formed at lower ends on both sides of the separation wall 31. Further, a guide pin 34 having a guide restricting piece 33 formed at the lower end is provided at a position upstream (right side in FIG. 10) of the separation wall 31 in the arm portion 8 of the lower case 3. A pair of guide restricting pieces 35 are formed in a portion of the upper case 2 that constitutes the arm 8, corresponding to the respective guide restricting pieces 32 provided at the lower ends on both sides of the separation wall 31.
[0035]
When the upper case 2 and the lower case 3 are joined to form the tape cassette 1, the running of the film tape 17 is guided in the arm portion 8 by the outer wall 8 </ b> B, the separation wall 31, and the guide pins 34. The film tape traveling path, the inner wall 8C, and the separation wall 31 form a ribbon traveling path that guides the traveling of the ink ribbon 19. At this time, the direction of the film tape 17 is changed by the guide pins 34 while the lower end thereof is regulated by the guide restricting pieces 33, and each of the guide restricting pieces 32 at the lower end of the separation wall 31 and each of the guide restricting pieces of the upper case 2. The guide is regulated in the width direction of the tape in cooperation with 35, so that the travel is guided between the outer wall 8B and the separation wall 31 in the arm portion 8. Further, the ink ribbon 19 is guided by the inner wall 8C and the separation wall 31 having substantially the same height as the width of the ribbon, while being guided between the inner wall 8C and the separation wall 31 in the arm portion 8. It is. At this time, the ink ribbon 19 is restricted in the width direction by the lower surface of the upper case 2 and the upper surface of the lower case 3.
[0036]
Here, as described above, the tape width of the film tape 17 and the ribbon width of the ink ribbon 19 are different from each other (the ribbon width of the ink ribbon 19 is larger than the tape width of the film tape 17). The path and the ribbon travel path are formed as different paths separated from each other via the separation wall 31 in the arm portion 8. Therefore, each of the fill tape 17 and the ink ribbon 19 has its own tape width and ribbon width. However, the vehicle can be independently and reliably guided in each traveling route. Since the ink ribbon 19 is guided by the inner wall 8C provided on the arm portion 8 of the lower case 3 and the separation wall 31, the ink ribbon 19 may be set only in the lower case 3; The ink ribbon 19 does not wrinkle between the cases 2 and 3 when the upper case 2 and the lower case 3 are assembled. Further, with respect to the inner wall 8C and the separation wall 31 which are formed higher than the outer wall 8B of the lower case 3 in consideration of the ribbon width of the ink ribbon 19, only necessary portions of the lower case 3 need to be formed higher. The portion can be formed in consideration of the balance with the height of the outer wall 8B and the wall height of the upper case 2. Therefore, the height of the entire lower case is adjusted in accordance with the height of the inner wall 8C and the separation wall 31. There is no need to increase it. Thus, the lower case 3 can be easily formed without any particular difficulty in forming.
[0037]
Returning to FIG. 2 and continuing the description of the internal structure of the tape cassette 1, an adhesive tape 22 with release paper is wound on the left side of the lower case 3 with the release paper side facing out. The tape spool 23 is rotatably supported via the support hole 7. As described above, the double-sided adhesive tape 22 is pulled out from the tape spool 23 by the cooperation of the tape feed roller 12 and the pressure roller 49 provided in the tape printer, and prints characters and the like via the thermal head H. The tape is adhered to the character printing surface of the film tape 17 and then discharged from the tape discharge unit 24 to the outside of the tape cassette 1.
[0038]
Next, the configuration of the tape spool 23 will be described with reference to FIGS. First, a state before the tape cassette 1 is mounted on the tape printer will be described with reference to FIGS. Here, FIG. 11 is a sectional view showing the tape spool 23 in a state where the lower case 3 of the tape cassette 1 is arranged on the lower side, and FIG. 12 is a sectional view of the tape spool 23 in a state where the lower case 3 is arranged on the upper side. .
[0039]
First, in FIG. 11, a plurality of locking ribs 36 are formed radially from the center of the support hole 7 in the upper case 2, and around the support hole 7 in the lower case 3. Like the locking ribs 36, a plurality of locking ribs 37 are formed radially from the center. The tape spool 23 has a double wall structure, and four sliding grooves 38 are formed on the inner inner wall 23A along the up-down direction. That is, each of the four sliding grooves 38 is formed in the vertical direction at 90-degree intervals on the inner wall 23A.
[0040]
Further, in the tape spool 23, there are formed four sliding projections 39 slidably fitted in the respective sliding grooves 38, and a cylindrical piece member 40 sliding vertically in the tape spool 23 is provided. It is inserted. Each sliding protrusion 39 can be locked to the locking rib 37 of the lower case 3 or the locking rib 36 of the upper case 2 according to the arrangement state of the tape cassette 1. For example, as shown in FIG. 11, when the tape cassette 1 is arranged such that the lower case 3 is on the lower side, each sliding protrusion 39 of the top member 40 is In the case where the tape cassette 1 is turned upside down so that the upper case 2 is on the lower side as shown in FIG. It is locked by the rib 36. When the sliding protrusions 39 of the top member 40 are not locked by either the locking rib 36 on the upper case 2 or the locking rib 37 on the lower case 3, the top member 40 Since the moving projection 39 is fitted in the sliding groove 38 of the tape spool 23, it is synchronously rotated with the tape spool 23.
[0041]
In the above configuration, each sliding projection 39 of the top member 40 is locked by the locking rib 37 of the lower case 3 in the state shown in FIG. As a result, the rotation of the tape spool 23 is locked. Similarly, in the state shown in FIG. 12, each sliding protrusion 39 of the top member 40 is locked by the locking rib 37 of the upper case 2 and is fitted into the sliding groove 38 of the tape spool 23. As a result, the rotation of the tape spool 23 is locked.
[0042]
Therefore, even when the tape cassette 1 is arranged in any of the states shown in FIGS. 11 and 12, the rotation of the tape spool 23 is locked, and the adhesive tape 22 is inadvertently removed from the tape cassette 1. It is possible to reliably prevent the tape cassette 1 from being pulled out or retracted into the tape cassette 1.
[0043]
Further, a state in which the tape cassette 1 is mounted on the cassette mounting portion X of the tape printer will be described with reference to FIG. FIG. 13 is a sectional view showing a state of the top member 40 when the tape cassette 1 is mounted on the cassette mounting portion X. In FIG. 13, a boss 41 is provided upright in the cassette mounting portion X of the tape printer in correspondence with the support hole 7 of the tape cassette 1, and the boss 41 is inserted into the support hole 7 when the tape cassette 1 is mounted. Inserted.
[0044]
When the tape cassette 1 is mounted on the cassette mounting portion X of the tape printing apparatus, the boss 41 is inserted into the support hole 7 of the tape cassette 1, and accordingly, the top member 40 is pushed upward in the tape spool 23. As a result, the engagement between the sliding protrusion 39 of the top member 40 and the locking rib 37 of the lower case 3 is released, and the tape spool 23 becomes rotatable together with the top member 40. Therefore, the double-sided adhesive tape 22 can be pulled out from the tape spool 23 via the tape feed roller 12 or the like, and a normal tape making operation can be performed. In FIG. 13, the tape cassette 1 is mounted on the cassette mounting portion X with the lower case 3 on the lower side, but the tape cassette 1 is turned upside down so that the upper case 2 is on the lower side. When the cassette member is mounted on the cassette mounting portion X, the top member 40 is moved upward in the tape spool 23 via a boss (not shown) formed on a lid provided on the tape printer and opening and closing the cassette mounting portion X. As a result, the engagement between the sliding protrusion 39 of the top member 40 and the locking rib 36 of the upper case 2 is released, and as a result, the tape spool 23 becomes rotatable together with the top member 40. Accordingly, in such a case, as in the case shown in FIG. 13, the double-sided adhesive tape 22 can be pulled out from the tape spool 23 via the tape feed roller 12 and the like, and a normal tape making operation can be performed.
[0045]
As described above, when the tape cassette 1 is not mounted on the cassette mounting portion X of the tape printing apparatus, the sliding projection 39 of the top member 40 is engaged with the upper case 2 when the tape spool 23 around which the double-sided adhesive tape 22 is wound. Since the stopper rib 36 or the locking rib 37 of the upper case 3 and the sliding groove 38 of the tape spool 23 are locked and fitted, the rotation of the tape spool 23 is locked and the double-sided adhesive tape 22 is Inadvertent withdrawal from the tape cassette 1 and withdrawal into the tape cassette 1 can be reliably prevented. When the tape cassette 1 is mounted on the cassette mounting portion X of the tape printing apparatus, the sliding protrusion 39 of the top member 40 and the locking rib of the upper case 2 are connected via the boss 41 erected on the mounting portion X. Since the lock with the locking rib 37 of the upper case 3 is released, the tape making operation can be performed by freely rotating the tape spool 23 without applying a rotational load to the tape spool 23. It is.
[0046]
Next, the configuration of the tape feed roller 12 will be described with reference to FIG. 14A and 14B are explanatory diagrams showing the tape feed roller 12, FIG. 14A is a cross-sectional view of the tape feed roller 12, and FIG. 14B is a plan view of the tape feed roller 12.

A cam member 69 of a tape drive cam 70 (described later) disposed on the cassette mounting portion X of the tape printer is engaged with each drive rib 43, and the tape feed roller 12 rotates the tape drive cam 70. In accordance with the movement, the cam member 69 and the driving ribs 43 rotate in cooperation with each other. As a result, the tape feeding roller 12 adheres the double-sided adhesive tape 22 to the film tape 17 and cooperates with the pressing roller 49 to transfer the tapes 22 and 17 from the tape discharge unit 24 to the outside of the tape cassette 1. This is to perform a sending operation. Further, since each drive rib 43 is provided vertically symmetrically on both sides of the center position M, in the case of front loading in which the tape drive cam 70 is inserted from below the tape feed roller 12, In any of the bottom loading cases where the tape drive cam 70 is inserted from above, the cam member 69 of the tape drive cam 70 can be engaged with each drive rib 43.
[0048]
Next, the relationship between the head holder of the thermal head H and the head mounting portion 9 and the relationship between the tape feed roller 12 and each of the regulating members 14 and 15 near the upstream side will be described with reference to FIGS. First, the relationship between the head holder of the thermal head H and the head mounting portion 9 will be described with reference to FIG.
[0049]
FIG. 15 is an enlarged explanatory view showing the relationship between the head holder of the thermal head H and the head mounting portion 9 when the tape cassette 1 is mounted on the cassette mounting portion X of the tape printing apparatus.

In the above configuration, after characters and the like are printed on the film tape 17 via the ink ribbon 19 by the thermal head H, the ink ribbon 19 consumed in the printing is wound around the ribbon spool 21 and the film tape 17 is The sheet is fed in the discharge direction by the tape feed roller 12 and the pressing roller 49. At this time, as described above, the ink ribbon 19 has a tape width larger than the tape width of the film tape 17, and therefore, is not sent out between the respective regulating members 14 and 15 and is guided by the regulating wall 51. It is wound around the ribbon spool 21 through the guide groove 25A between the wall 25. On the other hand, the film tape 17 has a tape width equal to the width W between the respective regulating members 14 and 15, and is fed to the tape feed roller 12 while being regulated and guided in the tape width direction by the respective regulating members 14 and 15. At the same time, the double-sided adhesive tape 22 is fed to the film tape 17 while being matched with the tape feed width W of the tape feed roller 12 equal to the tape width. As a result, the film tape 17 and the double-sided adhesive tape 22 having the same tape width can be properly bonded to each other by the cooperation of the tape feed roller 12 and the pressing roller 49 without any positional displacement between the two tapes. Things.
[0055]
Next, a description will be given of a characteristic configuration in which the tape cassette 1 can be used for a tape printing apparatus in both front loading and bottom loading. In the above description, in order to be usable in both front loading and bottom loading, each engagement rib 30 in the ribbon take-up spool 2 is formed vertically symmetrically (see FIG. 9), and a tape is provided. Although the configuration in which the drive ribs 43 of the feed roller 12 are formed vertically symmetrically (see FIG. 14) has been described, the tape cassette 1 according to the present embodiment has the following characteristic features in addition to these configurations. Having a configuration. That is, FIG. 18 is a side view of the tape cassette 1.

However, the tape cassette 1 is provided with a common part 52 having a height T which is formed symmetrically in the vertical direction with respect to a center line N in the height (width) direction of the tape cassette 1. The height T of the common portion 52 is set to the same size regardless of the tape width of the film tape 17 or the like.
Accordingly, the two-sided position of the common portion 52 is located at the same position with respect to the center line N from both the upper and lower directions of the tape cassette 1. And can be used in both front loading and bottom loading. In addition, positioning in the height direction can be performed using both the upper and lower surfaces of the common portion 52, and a pressing member provided on a lid for opening and closing the cassette mounting portion X of the tape printer is brought into contact with the common portion 52. By doing so, it is possible to easily design the lid regardless of whether the lid is disposed on the upper side or the lower side of the tape printer.
[0056]
As shown in the plan view of FIG. 19A and the back view of FIG. 19B, when the tape cassette 1 is mounted on the cassette mounting portion X, the tape cassette 1 stands upright from the cassette mounting portion X. Pin holes 53 and 54 into which the provided two positioning pins 72 and 73 (described later) are inserted are provided so as to be vertically symmetrical from both sides of the tape cassette 1.

As shown in FIGS. 19A and 19B, the position of the pin hole 53 is near the position where the tape feed roller 12 is arranged, and the position of the pin hole 54 is This is near the position where the cassette detection unit 16 is provided.
[0057]
Next, a case where the tape cassette 1 configured as described above is front-loaded to the cassette mounting portion X of the tape printing apparatus will be described with reference to FIGS. 20, 21, and 24. Here, FIG. 20 is an explanatory diagram showing a state in which the tape cassette 1 is front-loaded into the cassette mounting portion X of the tape printer, and FIG. 21 is a relation between the cassette detection unit 16 and the detection switch when the tape cassette 1 is front-loaded. FIG. 24 is an explanatory view schematically showing the case of front loading and the case of bottom loading.
[0058]
First, the configuration of the cassette mounting portion X of the tape printer P will be described with reference to FIG. In the cassette mounting portion X, a head holder 44 is fixedly provided in front of the cassette mounting portion X, and a thermal head H is mounted on the head holder 44. A drive motor 60 is disposed outside the cassette mounting portion X (right side in FIG. 20), and a drive gear 61 is fixed to a lower end of a drive shaft of the drive motor 60. The driving gear 61 is meshed with a gear 63 rotatably supported on the bottom surface of the cassette mounting portion X via an opening 62 provided in the cassette mounting portion X. The gear 63 is further meshed with a gear 64. ing. On the upper surface of the gear 64, a ribbon take-up shaft 65 for driving the rotation of the ribbon take-up spool 21 is erected, and is formed around the ribbon take-up shaft 65 on the inner wall of the ribbon take-up spool 21. A cam member 66 is provided for engaging with the engaged rib 30 (see FIG. 9).
[0059]
A gear 67 is meshed with the gear 64, and a gear 68 is meshed with the gear 67. The gear 68 meshes with a gear 71 on which a tape drive cam 70 having a cam member 69 engaging with the drive rib 43 (see FIG. 14) of the tape feed roller 12 is provided.
[0060]
When the tape cassette 1 is mounted on the cassette mounting portion X from the state shown in FIGS. 20 and 24 (center view, lower side view), when the drive motor 60 is rotated counterclockwise in the tape drive system, The ribbon take-up shaft 65 is driven to rotate counterclockwise through the drive gear 61, the gear 63, and the gear 64, and as a result, by cooperation with the cam member 66 and the engagement rib 30 of the ribbon take-up shaft 65, The ribbon take-up spool 21 is driven to rotate in the direction of arrow E to take up the ink ribbon 19. Further, the rotation of the gear 64 is transmitted to the tape driving cam 70 via the gear 67, the gear 68, and the gear 71, whereby the cam member 69 of the tape driving cam 70, and the driving rib 43 of the tape feed roller 12, The tape feed roller 12 is driven to rotate in the clockwise direction, and is discharged from the tape discharge unit 24 to the outside of the tape cassette 1 while adhering the film tape 17 and the double-sided adhesive tape 22 in cooperation with the pressing roller 49.
[0061]
Further, a boss (see FIG. 13) 41 is disposed between the gear 67 and the gear 68 in the cassette mounting portion X. As described above, when the tape cassette 1 is mounted on the cassette mounting portion X, the boss 41 pushes the top member 40 in the tape spool 23 upward, and the sliding protrusion 39 of the top member 40 and the lower case 3 The lock with the locking rib 37 is released. As a result, the tape spool 23 becomes free to rotate and can rotate together with the frame member 40.
[0062]
Further, two positioning pins 72 and 73 are provided around the cassette mounting portion X, and these positioning pins 72 and 73 are provided in the above-described pin holes 53 and 54 (FIGS. 19A and 19B). ) To properly position the tape cassette 1 in the cassette mounting portion X.
[0063]
Next, the relationship between the cassette detection unit 16 and the detection switch when the tape cassette 1 is front-loaded will be described with reference to FIG. In FIG. 21, a switch support member 80 is provided at a position behind the cassette mounting portion X, and four detection switches 81 are arranged on the switch support member 80 in an upward direction. Each detection switch 81 has a switch terminal 81A, and each detection switch 81 is in an off state when each switch end 81A enters a switch hole 16A formed in the switch detection section 16 of the tape cassette 1 in a predetermined pattern. On the other hand, in a portion where the switch hole 16A does not exist, the switch terminal 81A is pressed down, so that it is turned on. The type of the tape cassette 1 is detected based on the combination of ON / OFF of each of the detection switches 81.
[0064]
When the tape cassette 1 is mounted on the cassette mounting section X as described above, in the example of FIG. 21, two switches 81 on both sides are turned on except for the middle two switches 81 among the four detection switches 81. Therefore, since the on / off pattern is “on / off / off / on” from the left side, the type of the tape cassette 1 is detected based on such a combination.
[0065]
Next, a case where bottom loading of the tape cassette 1 to the cassette mounting portion X of the tape printing apparatus will be described with reference to FIGS. 22, 23, and 24. Here, FIG. 22 is an explanatory diagram showing a state in which the tape cassette 1 is bottom-loaded into the cassette mounting portion X of the tape printer, and FIG. 23 is a relationship between the cassette detection unit 16 and the detection switch when the tape cassette 1 is bottom-loaded. FIG.
[0066]
In the bottom-loading type tape printing apparatus P, the cassette mounting portion X is provided on the upper side differently from the case of FIG. 20, and the cassette mounting portion X is described in FIG. The same tape drive system and head holder 44 as those described above are disposed downward. Since these tape drive systems, the head holder 44, and the like have the same configuration, the description is omitted here.
[0067]
As shown in FIGS. 22 and 24 (upper view, central view), in the case of bottom loading, the tape cassette 1 is mounted on the cassette mounting portion X upward. At this time, in the tape cassette 1 according to the present embodiment, as described above, the engaging ribs 30 are formed vertically symmetrically in the ribbon take-up spool 21 (see FIG. 9), and Each drive rib 43 is formed vertically symmetrically (see FIG. 14), and a common portion 52 is provided vertically symmetrically along the height direction of the tape cassette 1 (see FIG. 18). Therefore, when the tape cassette 1 is bottom-loaded from the state shown in FIGS. 22 and 24 upward to the cassette mounting portion X, the tape cassette 1 is moved to the cassette mounting portion X in the same manner as in the case of the front loading. It is mounted with a relationship (relationship between each member in the tape cassette 1 and the tape drive system in the cassette mounting portion X). In the case of such bottom loading, the frame member 40 disposed in the tape spool 23 is moved upward via a boss provided on the tape printing apparatus P and formed on a lid for opening and closing the cassette mounting portion X. As a result, the tape spool 23 is brought into a free rotation state together with the frame member 40.
[0068]
Next, the relationship between the cassette detection unit 16 and the detection switch when the tape cassette 1 is bottom-loaded will be described with reference to FIG. In FIG. 23, a switch support member 80 is provided at a position behind the cassette mounting portion X, and the switch support member 80 is disposed above the tape cassette 1. On the switch support member 80, four detection switches 81 are juxtaposed downward. Each detection switch 81 has a switch terminal 81A, and each detection switch 81 is in an off state when each switch end 81A enters a switch hole 16A formed in the switch detection section 16 of the tape cassette 1 in a predetermined pattern. On the other hand, in a portion where the switch hole 16A does not exist, the switch terminal 81A is pressed down, so that it is turned on. The type of the tape cassette 1 is detected based on the combination of ON / OFF of each of the detection switches 81.
[0069]
When the tape cassette 1 is mounted on the cassette mounting portion X as described above, in the example of FIG. 23, two switches 81 on both sides of the four detection switches 81 are turned on except for the middle two switches 81. Therefore, since the on / off pattern is “on / off / off / on” from the left side, the type of the tape cassette 1 is detected based on such a combination.
[0070]
As described above in detail, in the tape cassette 1 according to the present embodiment, the ribbon width of the ink ribbon 19 is configured to be wider than the tape width of the film tape 17, and the pair of regulating members 14 are positioned near the tape roller 12. , 15 are provided, and the width W between the respective regulating members 14, 15 is set to be substantially the same as the tape width of the film tape 17. Thus, the film tape 17 and the ink ribbon 19 are reliably separated from each other, so that the ink ribbon 19 can be reliably prevented from traveling to the downstream side of each of the regulating members 14 and 15. Further, on the downstream side of each of the regulating members 14 and 15, the ink ribbon 19 is not pulled out more than necessary as the film tape 17 runs.
[0071]
Thereby, even when the ink ribbon 19 is slightly loosened, the ink ribbon 19 stuck to the film tape 17 is pulled out more than necessary due to the drawing out of the film tape 17 and Adhesion can reliably prevent the ink ribbon 19 from jamming inside the tape cassette 1 and making the tape cassette 1 unusable.
[0072]
Also, by making the ribbon width of the ink ribbon 19 larger than the tape width of the film tape 17, the ribbon width of the ink ribbon 19 naturally becomes larger than the printing width of characters and the like on the film tape 17, thereby increasing the film width. Even when characters and the like are continuously printed using the printing width of the tape 17 to the maximum, the ink ribbon 19 is cut because the unused portion of the ink ribbon 19 remains on both sides of the printing width. That can be prevented.
[0073]
Further, regarding the attachment of the film tape 17 and the ink ribbon 19 to the tape spool 18 and the ribbon spool 20, respectively, the end 17A of the film tape 17 and the end 19A of the ink ribbon 19 are attached to the tape spool 18 and the ribbon spool 20, respectively. The adhesive tape 27 is adhered between the two ends 27A of the adhesive tape 27 around the periphery thereof, so that the film tape 17, the ends 17A and 19A of the ink ribbon 19 are separated from the adhesive tape 27 by the tape spool 18, the ribbon spool The film tape 17 and the ink ribbon 19 are firmly fixed to the tape spool 18 and the ribbon spool 20 via the adhesive tape 27 to such an extent that they can sufficiently oppose the force to be peeled off from the spool 20. Make sure that it is easily peeled off from 20 It is possible to stop.
[0074]
Further, in the tape cassette 1 of the present embodiment, by forming the separation wall 31 on the arm portion 8, the film tape 17 is guided to travel between the outer wall 8B and the separation wall 31, and the ink ribbon 19 is moved to its ribbon width. Is configured to be guided between the inner wall 8C having substantially the same height as the inner wall 8C and the separation wall 31, so that the fill tape 17 and the ink ribbon 19 can be formed in spite of different tape widths and ribbon widths. Thus, it is possible to reliably and independently guide the travel in each travel route. Since the ink ribbon 19 is guided by the inner wall 8C provided on the arm portion 8 of the lower case 3 and the separation wall 31, the ink ribbon 19 may be set only in the lower case 3; Between the cases 2 and 3 when the upper case 2 and the lower case 3 are assembled with each other. Further, with respect to the inner wall 8C and the separation wall 31 which are formed higher than the outer wall 8B of the lower case 3 in consideration of the ribbon width of the ink ribbon 19, only necessary portions of the lower case 3 need to be formed higher. The portion can be formed in consideration of the balance with the height of the outer wall 8B and the wall height of the upper case 2. Therefore, the height of the entire lower case is adjusted in accordance with the height of the inner wall 8C and the separation wall 31. There is no need to increase it. Thus, the lower case 3 can be easily formed without any particular difficulty in forming.
[0075]
Further, four sliding grooves 38 are formed on the inner wall 23A of the tape spool 23 around which the double-sided adhesive tape 22 is wound, and a top member 40 having sliding protrusions 39 fitted into each sliding groove 38 is attached to the tape spool 23. The sliding protrusions 39 of the top member 40 are slidably disposed in the tape cassette 1 and the respective locking protrusions 36 formed around the support holes 7 of the upper case or the lower case 3. The rotation of the tape spool 23 is held in a locked state by being locked to each of the engaging ribs 37 formed around the support hole 7, so that the adhesive tape 22 is inadvertently pulled out of the tape cassette 1. The tape cassette 1 can be reliably prevented from being pulled out or pulled into the tape cassette 1.
[0076]
Further, regarding the relationship between the head holder 44 on which the thermal head H is mounted and the head mounting portion 9, the first fitting portion 10 is provided on the wall 9A of the head mounting portion 9 and the first fitting portion 10 is provided on the side wall of the head mounting portion 9. The first fitting portion 11 is inserted into the first fitting portion 10 and the second fitting portion 11 is inserted into the head holder 44. When the tape cassette 1 is mounted on the cassette mounting portion X, the tape cassette 1 is mounted while always maintaining a constant relationship with the cassette mounting portion X by providing the second protrusion 46. As a result, the tape cassette 1 can be securely and easily inserted into the cassette mounting portion X without the film tape 17 and the ink ribbon 19 exposed at the head mounting portion 9 coming into contact with the thermal head H and the head holder 44. It can be mounted.
[0077]
Further, a plurality of engagement ribs 30 are formed on the inner wall of the ribbon take-up spool 21 in a vertically symmetrical manner, and a plurality of drive ribs 43 are formed radially from the inner wall of the cylindrical portion 42 of the tape feed roller 12 in a vertically symmetrical manner. Therefore, the cam member 66 of the ribbon take-up shaft 65 and the cam member 71 of the tape drive cam 70 can be used for both front loading and bottom loading of the tape cassette 1 to the cassette mounting portion X of the tape printer P. Can be engaged with both.
