The inventor has found the following problems.
In order to obtain a uniform printing result in the tape width direction (hereinafter referred to as “tape width direction”) when printing on a tape of a tape cartridge mounted on the tape printing apparatus by a tape printing apparatus having a print head. In the state where the tape cartridge is mounted, it is preferable that the center of the tape (hereinafter referred to as “tape center”) is located at a predetermined position of the print head in the tape width direction. On the other hand, in the case of multiple types of tape cartridges with different tape widths, in order to prevent the tape from rattling in the cartridge case, the tape should be kept as small as possible between the cartridge case and the tape in the tape width direction. It is conceivable to use cartridge cases having different sizes depending on the width of the cartridge. When such a tape cartridge is attached to the tape printer with one end in the tape width direction as a reference, depending on the type of the tape cartridge, the center of the tape will deviate from a predetermined position of the print head, Print quality decreases.

It is an object of the present invention to provide a tape cartridge that enables good printing regardless of the type of tape cartridge among a plurality of types of tape cartridges having different tape widths.

The tape cartridge of the present invention is a plurality of types of tape cartridges having different tape widths, and is one of the plurality of types of tape cartridges selectively mounted on a common tape printer. A roll body in which a tape is wound in a roll shape, a roll body is accommodated, and is provided between a cartridge case common to a plurality of types of tape cartridges and a first end surface which is one end surface of the cartridge case and the roll body. In the tape width direction, which is the width direction of the tape, a spacer portion having different dimensions in the tape width direction and a cartridge case for each type of tape cartridge so that the position of the center of the tape is common to a plurality of types of tape cartridges And the second end surface which is the other end surface of the roll body, the roll body being the first end surface Characterized by comprising a biasing member for biasing.

In this configuration, the roll body is pressed against the spacer portion by the biasing member. Therefore, according to this configuration, even when a common cartridge case is used for a plurality of types of tape cartridges, it is possible to prevent the roll body from rattling within the cartridge case. In this configuration, a common cartridge case is provided for a plurality of types of tape cartridges. Further, the position of the tape center is common to a plurality of types of tape cartridges. For this reason, when the tape cartridge is mounted in the tape printer, the center of the tape is located at a predetermined position of the print head of the tape printer in any type of tape cartridge. Therefore, according to this configuration, in a plurality of types of tape cartridges having different tape widths, good printing can be performed regardless of the type of the tape cartridge.

In this case, it is preferable that the urging member has a plate portion in contact with the second end face and a spring portion that can be bent.

In this configuration, the spring portion urges the roll body with the surface via the plate portion in contact with the second end surface. Therefore, according to this configuration, the roll body can be urged in a well-balanced manner without increasing the number of parts.

In this case, the cartridge case has a rib provided on the wall portion facing the second end surface, the spring portion includes a continuous portion connected to the plate portion, and a contact portion in contact with the cartridge case. It is preferable that the tape rotates when the tape is unwound, the continuous part is located behind the roll body in the rotational direction, and the contact part is located ahead of the roll body in the rotational direction.

When the urging member rotates when the tape is paid out, a sound is generated in which the contact portion of the spring portion that has passed through the rib hits the cartridge case. On the other hand, in this configuration, when the tape is fed out and the roll body starts to rotate, and the urging member starts to rotate along with this, the contact portion of the spring portion abuts against the rib of the cartridge case. Thereby, rotation of an urging member stops, and after that, a roll body rotates, making sliding contact with a stationary urging member. Therefore, according to this configuration, the rotation of the urging member is suppressed when the tape is fed out, and the occurrence of the sound that the contact portion hits the cartridge case is suppressed.

In this case, it is preferable that the urging member has a plurality of spring portions, and the plurality of spring portions are provided in the plate portion so as to be dispersed in the circumferential direction of the plate portion.

According to this configuration, the roll body can be urged with good balance by the urging member.

In this case, the wall portion facing the second end surface of the cartridge case and the urging member are preferably translucent.

According to this configuration, the remaining amount of the tape in the roll body can be visually recognized through the wall portion and the biasing member facing the second end surface.

In this case, the biasing member is preferably common to a plurality of types of tape cartridges.

According to this configuration, since it is not necessary to prepare a plurality of types of urging members, it is possible to suppress an increase in cost required for the urging members.

The platen drive shaft 107 is engaged with the platen roller 4 in a state where the tape cartridge A is mounted on the cartridge mounting portion 104. In this state, the platen roller 4 sandwiches the tape 511 and the ink ribbon 21 with the print head 106. When the platen drive shaft 107 rotates, the platen roller 4 engaged therewith also rotates. As a result, the tape 511 and the ink ribbon 21 sandwiched between the platen roller 4 and the print head 106 are fed.

The tape roll 5 will be described with reference to FIG. The tape roll 5 includes a roll body 51 and a tape core 52.

The roll body 51 includes a tape 511 and an adhesive film 512. The tape 511 is wound around the tape core 52 in a roll shape. The tape 511 may be, for example, a band shape or a flat cylindrical shape (for example, a heat shrinkable tube). The adhesive film 512 is affixed to the end surface on the + Z side of the tape 511 wound in a roll shape. That is, the adhesive film 512 constitutes a second end surface 51 b (see FIG. 6) that is an end surface on the + Z side of the roll body 51. The adhesive film 512 is formed in a substantially annular film shape having a slightly larger outer diameter than that of the unused roll body 51. The adhesive film 512 prevents the roll body 51 from being separated when the tape roll 5 is handled in the manufacturing process of the tape cartridge A. Note that the adhesive film 512 is translucent.

The tape core 52 includes a core part 521 and a spacer part 522. Tape 511 is wound around core portion 521 in a roll shape. The core portion 521 is formed in a substantially cylindrical shape with the Z direction as an axis, and the core shaft 1112 is inserted into the core portion 521. The spacer portion 522 is provided at the end on the −Z side of the core shaft 1112. That is, the spacer portion 522 is provided between the first end surface 51a (see FIG. 6), which is the end surface on the −Z side of the roll body 51, and the first opposing wall portion 111. The spacer portion 522 is formed in a hollow, substantially annular plate shape having an outer diameter slightly larger than that of the unused roll body 51.

The relationship between the thickness of the spacer portion 522 and the width of the tape 511 will be described with reference to FIG. The thickness of the spacer portion 522, that is, the dimension in the tape width direction, is set so that the position of the center of the tape 511 (hereinafter referred to as “tape center”) in the tape width direction is common to a plurality of types of tape cartridges A. ing. In addition, the dashed-dotted line 511p shown in the figure shows the position of the tape center in the Z direction. For this reason, the thin spacer portion 522 is used in the tape cartridge A in which the wide tape 511 is accommodated, and the thick spacer portion 522 is used in the tape cartridge A in which the narrow tape 511 is accommodated. In the tape cartridge A in which the tape 511 having the maximum width is accommodated, the spacer portion 522 may be omitted.

The spring member 6 will be described with reference to FIG. The spring member 6 is provided between the second end surface 51b of the roll body 51 and the second opposing wall 121 facing the second end surface 51b. The spring member 6 biases the roll body 51 toward the first end face 51a (−Z side). The spring member 6 is a molded product of translucent resin. The spring member 6 includes a plate portion 61 and a plurality (three in this case) of spring portions 62.

The plate part 61 is in contact with the second end surface 51 b of the roll body 51. The plate portion 61 is formed in a thin, substantially annular plate shape having a slightly larger outer diameter than the unused roll body 51. The plate portion 61 is provided with an arcuate spring opening 611 that is slightly larger than the spring portion 62 when viewed from the + Z side at a position corresponding to the spring portion 62. A circular opening 612 is provided in the approximate center of the plate portion 61. A core portion 521 is inserted into the circular opening 612.

The three spring portions 62 are provided on the plate portion 61 so as to be distributed at substantially equal angular intervals in the circumferential direction of the plate portion 61. The spring part 62 is formed in an arc shape when viewed from the + Z side, and is formed so as to rise obliquely from the plate part 61 to the + Z side. The continuous portion 621 corresponding to the base end of the spring portion 62 is continuous with the plate portion 61 at one end in the length direction of the spring opening 611. A contact portion 622 corresponding to the tip of the spring portion 62 is in contact with the second opposing wall portion 121. The continuous portion 621 is located in the clockwise rearward direction, that is, in the rearward direction of the tape roll 5 when viewed from the + Z side. Further, the contact portion 622 is located in the clockwise direction, that is, in the rotational direction of the tape roll 5 as viewed from the + Z side.

The spring portion 62 can be bent, and the amount of bending changes according to the width of the gap between the roll body 51 and the second opposing wall portion 121. That is, in the tape cartridge A in which the wide tape 511 is accommodated, since the gap between the roll body 51 and the second opposing wall portion 121 is narrow, the amount of bending of the spring portion 62 increases. On the other hand, in the tape cartridge A in which the narrow tape 511 is accommodated, since the gap between the roll body 51 and the second opposing wall portion 121 is wide, the bending amount of the spring portion 62 is small. For this reason, the spring member 6 can appropriately bias the roll body 51 regardless of the width of the tape 511.

By the way, when the tape 511 is fed out and the tape roll 5 rotates, the spring member 6 will also rotate due to the friction between the second end face 51b of the roll body 51 and the -Z side surface of the plate portion 61 of the spring member 6. And

With reference to FIG. 8 and FIG. 9, the aspect of the spring member 6 when the tape 511 is drawn out from the roll body 51 in the tape cartridge B according to the embodiment different from the tape cartridge A shown in FIG. . The tape cartridge B is configured in substantially the same manner as the tape cartridge A, but in the spring member 6, the continuous portion 621 of the spring portion 62 is positioned ahead of the tape roll 5 in the rotation direction, and the contact portion 622 is the tape roll. 5 is different in that it is located rearward in the direction of rotation. In this case, while the tape roll 5 is rotating, the spring member 6 also continues to rotate, and the sound of the contact portion 622 hitting the cartridge case 1 is generated intermittently. This is because, in this case, when the spring member 6 rotates, the spring portion 62 comes into contact with the rib 1212 at a position between the continuous portion 621 and the contact portion 622 and is bent toward the −Z side (see FIG. 8). . This is because when the spring member 6 further rotates from this state, the contact portion 622 passes through the rib 1212, and the contact portion 622 that has passed through the rib 1212 again hits the second opposing wall portion 121 by the spring force of the spring portion 62. (See FIG. 9).

On the other hand, in the tape cartridge A, it is suppressed that the spring member 6 continues to rotate while the tape roll 5 is rotating, and the sound of the contact portion 622 hitting the cartridge case 1 is suppressed. Hereinafter, the aspect of the spring member 6 when the tape 511 is drawn out from the roll body 51 in the tape cartridge A of the embodiment will be described with reference to FIGS. 10 and 11.

FIG. 10 shows a state where the contact portion 622 of the spring portion 62 of the spring member 6 and the rib 1212 of the second case 12 are separated from each other. In this state, when the tape 511 is fed out from the tape roll 5, the tape roll 5 starts to rotate clockwise as viewed from the + Z side, and accordingly, the spring member 6 also starts to rotate clockwise as viewed from the + Z side. . Here, as described above, in the tape cartridge A of the embodiment, in the spring member 6, the contact portion 622 of the spring portion 62 is positioned ahead of the tape roll 5 in the rotation direction, and the continuous portion 621 is the tape roll 5. Located rearward in the direction of rotation. For this reason, when the spring member 6 starts rotating, the contact portion 622 of the spring portion 62 abuts against the side surface of the rib 1212 of the second case 12 as shown in FIG. Thereby, the rotation of the spring member 6 is stopped, and thereafter, the tape roll 5 rotates while being in sliding contact with the plate portion 61 of the stationary spring member 6. In this way, it is possible to suppress the sound that the contact portion 622 hits the cartridge case 1.

With reference to FIG. 12 and FIG. 13, the positional relationship between the tape 511 accommodated in the tape cartridge C according to the comparative example and the print head 106 will be described. Unlike the tape cartridge A of the embodiment, the tape cartridge C of the comparative example has a tape width according to the width of the tape 511 so that there is no gap as much as possible between the cartridge case 1 and the tape 511 in the tape width direction. A cartridge case 1 having different dimensions in the direction is provided. Further, the tape cartridge C is mounted with the first opposing wall portion 111 as a reference, similarly to the tape cartridge A of the embodiment. For this reason, when the tape cartridge C is mounted on the cartridge mounting portion 104, the tape center deviates from the head center depending on the type of the tape cartridge C. For example, as shown in FIG. 12, in the tape cartridge C in which the wide tape 511 is accommodated, the tape center is located at the head center, but as shown in FIG. 13, the narrow tape 511 is accommodated. In the tape cartridge C, the tape center is deviated from the head center. In the figure, the alternate long and short dash line 106p indicates the position of the head center in the Z direction. Then, in the tape cartridge C in which the tape center deviates from the head center, the tape 511 is not uniformly pressed by the print head 106 in the tape width direction, so that the print quality is deteriorated.

On the other hand, in the present embodiment, it is possible to perform good printing regardless of the type of the tape cartridge A in a plurality of types of tape cartridges A having different widths of the tape 511. Hereinafter, the positional relationship between the tape 511 accommodated in the tape cartridge A of this embodiment and the print head 106 will be described with reference to FIGS. 14 and 15.

As shown in FIGS. 14 and 15, in the tape cartridge A of this embodiment, as described above, a plurality of types of tape cartridges A having different widths of the tape 511 are common to the plurality of types of tape cartridges A. It has. Further, the thickness of the spacer portion 522 differs depending on the type of the tape cartridge A, and the position of the center of the tape is common to the plurality of types of tape cartridges A. For this reason, when the tape cartridge A is mounted on the cartridge mounting portion 104, the tape center is located at the head center in any type of tape cartridge A. As a result, in any type of tape cartridge A, since the tape 511 is uniformly pressed by the print head 106 in the tape width direction, a good printing result can be obtained.

As described above, the tape cartridge A of the present embodiment is a plurality of types of tape cartridges A having different widths of the tape 511, and is a plurality of types of tape cartridges A that are selectively mounted on the common tape printer P. This is one of the tape cartridges A. The tape cartridge A is provided between the roll body 51 in which the tape 511 is wound in a roll shape, the cartridge case 1 in which the roll body 51 is accommodated, and the cartridge case 1 and the first end surface 51 a of the roll body 51. A spacer portion 522 and a spring member 6 provided between the cartridge case 1 and the second end surface 51 b of the roll body 51 are provided. The cartridge case 1 is common to a plurality of types of tape cartridges A. The spacer portion 522 has different dimensions in the tape width direction for each type of tape cartridge A so that the position of the tape center of the tape 511 is common to the plurality of types of tape cartridges A in the tape width direction. The spring member 6 biases the roll body 51 toward the first end face 51a.
