     SUMMARY OF INVENTION 
     Technical Problem 
     The present inventor has found problems as follows. 
     In a case in which a tape printing device provided with a printing head performs printing on a tape of a tape cartridge mounted in the tape printing device, in order to obtain a result of a uniform printing in a width direction of the tape (hereinafter, refer to as a “tape width direction”), it is preferable that the center of the tape (hereinafter, referred to as a “tape center”) be positioned at a predetermined position of the printing head in the tape width direction in a state in which the tape cartridge is mounted. Meanwhile, in a plurality of types of the tape cartridges in which widths of the tapes are different, in order to suppress looseness of the tape inside a cartridge case, it is conceivable that the cartridge case having a varying size depending on the width of the tape is used so as to prevent the generation of a gap between the cartridge case and the tape in the tape width direction as much as possible. When such a tape cartridge is mounted in the tape printing device based on one end portion in the tape width direction, the tape center becomes deviated from a predetermined position of the printing head depending on the types of the tape cartridge, and thus a quality of printing is deteriorated. 
     An object of the invention is to provide the tape cartridge, which is capable of performing good printing regardless of the types of the tape cartridges, in the plurality of types of the tape cartridges in which widths of the tapes are different. 
     Solution to Problem 
     According to the invention, there is provided a tape cartridge of a plurality of types of tape cartridges in which widths of accommodated tapes are different and which is selectively mounted in a common tape printing device, the tape cartridge including a roll body around which the tape is wound in a roll shape, a cartridge case in which the roll body is accommodated and which is common to the plurality of types of the tape cartridges, a spacer portion that is provided between the cartridge case and a first end surface which is one end surface of the roll body, and has a varying size in a tape width direction depending on the type of the tape cartridge such that a position of the center of the tape is common to the plurality of types of the tape cartridges in the tape width direction which is a width direction of the tape, and an urging member that is provided between the cartridge case and a second end surface which is another end surface of the roll body and urges the roll body to a first end surface side. 
     In this configuration, the urging member presses the roll body with respect to the spacer portion. Therefore, according to the configuration, even in a case in which the cartridge case common to the plurality of types of the tape cartridges is used, looseness of the roll body inside the cartridge case is suppressed. In addition, in the configuration, the cartridge case common to the plurality of types of the tape cartridges is provided. In addition, a position of the tape center is common to the plurality of types of the tape cartridges. Therefore, when the tape cartridge is mounted in the tape printing device, even in any type of the tape cartridge, the tape center is positioned at a predetermined position of the printing head of the tape printing device. Therefore, according to the configuration, in the plurality of types of the tape cartridges in which widths of the tape are different, good printing can be performed regardless of the types of the tape cartridge. 
     In this case, it is preferable that the urging member include a plate portion in contact with the second end surface and a bendable spring portion. 
     In this configuration, the spring portion urges the roll body with a surface through the plate portion in contact with the second end surface. Therefore, according to the configuration, it is possible to urge the roll body in good balance without increasing the number of components. 
     In this case, it is preferable that the cartridge case include a rib which is provided on a wall portion facing the second end surface, the spring portion include a continuous portion which is continuous to the plate portion and a contact portion in contact with the cartridge case, the roll body be rotated when the tape is fed out, and the continuous portion be positioned behind in a rotating direction of the roll body, and the contact portion be positioned ahead in the rotating direction of the roll body. 
     At the time of feeding out the tape, when the urging member is rotated, sound of the contact portion of the spring portion passed through the rib, which is generated by the contact of the cartridge case, is generated. With respect to that, in this configuration, when the roll body from which the tape is fed out starts to rotate, and the urging member is rotated in accordance with the rotation of the roll body, the contact portion of the spring portion collides to the rib of the cartridge case. Accordingly, after the urging member stops to be rotated, the roll body is rotated while being slidably contact with the stopped urging member. Therefore, according to the configuration, at the time of feeding out the tape, the rotation of the urging member is suppressed, and generation of sound, which is generated by the contact of the contact portion with the cartridge case, is suppressed. 
     In this case, it is preferable that the urging member include a plurality of the spring portions, and the plurality of spring portions be dispersed in the circumferential direction of the plate portion, and is provided in the plate portion. 
     According to this configuration, it is possible to urge the roll body by the urging member in good balance. 
     In this case, it is preferable the wall portion facing the second end surface in the cartridge case and the urging member be translucent. 
     According to this configuration, an amount of remaining tape of the roll body can be visually recognized through the wall portion facing the second end surface and the urging member. 
     In this case, it is preferable that the urging member be common to the plurality of types of the tape cartridges. 
     According to this configuration, since it is unnecessary to prepare a plurality of types of the urging members, it is possible to suppress an increase in cost required for the urging member.

     DESCRIPTION OF EMBODIMENTS 
     Hereinafter, a tape cartridge A according to an embodiment of the invention will be described with reference to attached drawings. As the tape cartridge A, a plurality of types of tape cartridges in which widths of tapes  511  are respectively different are prepared, and the plurality of types of the tape cartridges A are selectively mounted in a common tape printing device P. Moreover, in the drawings hereinafter, as needed, in order to clarify an arrangement relationship of each portion such as the tape cartridge A, an XYZ orthogonal coordinate system is illustrated. 
     With reference to  FIG. 1 , first, the tape printing device P in which the plurality of types (only two types are illustrated in  FIG. 1 ) of the tape cartridges A are selectively mounted will be described. The tape printing device P is provided with an operating panel  101 , a display  102 , an openable lid  103 , a cartridge mounting portion  104 , and a tape discharging opening  105 . 
     The operating panel  101  receives an inputting and editing operation or the like of a character string being printed. The display  102  displays the character string during inputting and editing, various messages, and the like. The openable lid  103  opens and closes the cartridge mounting portion  104 . In the cartridge mounting portion  104 , the tape cartridge A is detachably mounted in the Z direction. In a state in which the tape cartridge A is mounted in the cartridge mounting portion  104 , a width direction of the tape  511  (hereinafter, referred to as a “tape width direction”) accommodated in the tape cartridge A is set as the Z direction. The cartridge mounting portion  104  is provided with a mounting bottom wall portion  1041  and a mounting circumferential wall portion  1042 . The tape cartridge A is mounted in the cartridge mounting portion  104  so as to be placed in the mounting bottom wall portion  1041 . In the mounting bottom wall portion  1041 , a printing head  106 , a platen driving shaft  107  and a winding driving shaft  108  are provided. In the tape discharging opening  105 , the tape  511 , on which printing is performed, sent from the tape cartridge A mounted in the cartridge mounting portion  104  is discharged. 
     With reference to  FIG. 2 , a head supporting portion  109  which supports the printing head  106  and the printing head  106  will be described. 
     The printing head  106  is provided with a plurality of heating elements  1061 . The heating elements  1061  are arranged on a surface of the printing head  106  in the Z direction, that is, a surface on a −Y side. The head supporting portion  109  is provided with a head supporting shaft  1091 , a head supporting frame  1092 , and the supporting point pin  1093 . In the head supporting shaft  1091 , an end portion on a −Z side is fixed to a base frame which is not illustrated and extends in the Z direction. The head supporting frame  1092  is supported by the head supporting shaft  1091  so as to be rotatable, and supports the printing head  106  on the −Y side. The supporting point pin  1093  extends in an X direction. The supporting point pin  1093  connects the printing head  106  to the head supporting frame  1092  so as to be able to be oscillated. 
     With reference to  FIGS. 1 and 2 , operations of the printing head  106  in association with the openable lid  103  will be described. When the openable lid  103  opens, the printing head  106  rotates around the head supporting shaft  1091  on a +Y side and evacuates from the platen driving shaft  107  by a head release mechanism (not illustrated) which connects the openable lid  103  to the head supporting frame  1092 . Accordingly, when the tape cartridge A is mounted in the cartridge mounting portion  104 , the tape  511  and an ink ribbon  21  are inserted between a platen roller  4  and the printing head  106  engaged with the platen driving shaft  107 . 
     Meanwhile, when the openable lid  103  is closed, the printing head  106  rotates around the head supporting shaft  1091  on the −Y side and approaches the platen driving shaft  107  by the head release mechanism. Therefore, when the openable lid  103  is closed in a state in which the tape cartridge A is mounted in the cartridge mounting portion  104 , the printing head  106  presses the tape  511  and the ink ribbon  21  to the platen roller  4  engaged with the platen driving shaft  107 . At this time, the printing head  106  oscillates with the supporting point pin  1093  as the center. Accordingly, the printing head  106  uniformly presses the tape  511  and the ink ribbon  21  with respect to the platen roller  4  in the Z direction. In this state, when the platen roller  4  is rotated, the tape  511  pinched between the platen roller  4  and the printing head  106  and the ink ribbon  21  are sent. In addition, ink of the ink ribbon  21  is transferred to the tape  511  due to heat applied to the ink ribbon  21  from the printing head  106 , and thus printing is performed on the tape  511 . 
     Moreover, a center around which the printing head  106  is oscillated in a tape width direction (Z direction), that is, a position of the supporting point pin  1093  is set as the center (hereinafter, referred to as a “head center”) of the printing head  106  in the tape width direction. 
     With reference to  FIG. 3 , the tape cartridge A will be described. The tape cartridge A is provided with a cartridge case  1 , a ribbon roll  2  (refer to  FIG. 1 ), a ribbon winding core  3  (refer to  FIG. 1 ), the platen roller  4 , a tape roll  5 , and a spring member  6 . As each component except tape roll  5 , regardless of the types of the tape cartridge A, that is, regardless of the width of the tape  511 , a common component is used. 
     The cartridge case  1  accommodates the ribbon roll  2 , the ribbon winding core  3 , the platen roller  4 , the tape roll  5 , and the spring member  6 . A tape delivery outlet  7  is provided on a surface on the −X side of the cartridge case  1 . The tape  511  fed out from the tape roll  5  is transported to the outside of the cartridge case  1  from the tape delivery outlet  7 . The cartridge case  1  is provided with a first case  11  and a second case  12 . The first case  11  and the second case  12  are joined to be able to be separated from each other. 
     The first case  11  is positioned on a depth side (−Z side) in a mounting direction in a state in which the tape cartridge A is mounted in the cartridge mounting portion  104 . The first case  11  is a non-translucent resin molded product. The first case  11  is provided with a first facing wall portion  111  and a first circumferential wall portion  112 . 
     The first facing wall portion  111  faces a second facing wall portion  121  to be described later. When the tape cartridge A is mounted in the cartridge mounting portion  104 , the first facing wall portion  111  comes into contact with the mounting bottom wall portion  1041 . That is, the tape cartridge A is mounted in the cartridge mounting portion  104  based on the first facing wall portion  111 . In a substantially half portion on the −Y side of the first facing wall portion  111 , a first tape accommodating area  1111  in a substantially circular shape seen from the +Z side is provided. The tape roll  5  is accommodated in the first tape accommodating area  1111 . A core shaft  1112  is provided on the +Z side so as to protrude to a substantially center of the first tape accommodating area  1111 . The tape roll  5  is supported by the core shaft  1112  so as to be rotatable. When the platen roller  4  is rotated and the tape  511  is fed out, the tape roll  5  is rotated in a clockwise direction seen from the +Z side. In addition, a first head opening (not illustrated) is provided at the corners on the −X side and the +Y side of the first facing wall portion  111 . When the tape cartridge A is mounted in the cartridge mounting portion  104 , the printing head  106  is inserted into the first head opening. 
     The first circumferential wall portion  112  is provided to protrude from a peripheral portion of the first facing wall portion  111  to the +Z side. A plurality of joining holes  1121  are provided on an end surface of the first circumferential wall portion  112 . 
     The second case  12  is positioned on a front side (+Z side) in the mounting direction in a state in which the tape cartridge A is mounted in the cartridge mounting portion  104 . The second case  12  is a translucent resin molded product. The second case  12  is provided with the second facing wall portion  121  and a second circumferential wall portion  122 . 
     The second facing wall portion  121  faces the first facing wall portion  111 . A second tape accommodating area  1211  in a substantially circular shape seen from the −Z side is provided on a substantially half portion on the −Y side of the second facing wall portion  121 , that is, a position corresponding to the first tape accommodating area  1111 . The tape roll  5  is accommodated on the second tape accommodating area  1211 . A plurality (here, three) of ribs  1212  are provided on the second tape accommodating area  1211  so as to protrude to the −Z side (refer to  FIG. 4 ). The three ribs  1212  radially extend from a substantially center of the second tape accommodating area  1211  at substantially equal angular intervals. In addition, a second head opening  1213  is provided at the corners on the −X side and the +Y side of the second facing wall portion  121 . When the tape cartridge A is mounted in the cartridge mounting portion  104 , the printing head  106  is inserted into the second head opening  1213 . 
     The second circumferential wall portion  122  is provided to protrude from a peripheral portion of the second facing wall portion  121  to the −Z side. A plurality of joining pins  1221  are provided on an end surface of the second circumferential wall portion  122  so as to protrude to the −Z side. The joining pin  1221  is pressed in the joining hole  1121  provided in the first circumferential wall portion  112 , and thus the first case  11  and the second case  12  are joined to each other. 
     The ribbon roll  2  is provided with the ink ribbon  21  and a ribbon feeding core  22  as illustrated in  FIG. 1 . The ink ribbon  21  is wound around the ribbon feeding core  22  in a roll shape. The ink ribbon  21  having a width corresponding to a width of the tape  511  having the widest width among the plurality of types of the tape cartridges A is commonly used to the plurality of types of the tape cartridges A. However, the width of the ink ribbon  21  may vary depending on the plurality of types of the tape cartridges A. 
     The winding driving shaft  108  is engaged with the ribbon winding core  3  in a state in which the tape cartridge A is mounted in the cartridge mounting portion  104 . Also, when the winding driving shaft  108  is rotated, the ribbon winding core  3  which is engaged with the winding driving shaft is also rotated. Accordingly, the ink ribbon  21  fed out from the ribbon feeding core  22  is wound around the ribbon winding core  3 . 
     The platen driving shaft  107  is engaged with the platen roller  4  in a state in which the tape cartridge A is mounted in the cartridge mounting portion  104 . In this state, the tape  511  and the ink ribbon  21  are pinched between the platen roller  4  and the printing head  106 . Also, when the platen driving shaft  107  is rotated, the platen roller  4  which is engaged with the platen driving shaft is also rotated. Accordingly, the tape  511  and the ink ribbon  21  pinched between the platen roller  4  and the printing head  106  are sent. 
     With reference to  FIG. 5 , the tape roll  5  will be described. The tape roll  5  is provided with a roll body  51  and a tape core  52 . 
     The roll body  51  is provided with the 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 belt shape, or may be a flat tubular shape (for example, a thermal shrinking tube). The adhesive film  512  is adhered to an end surface on the +Z side of the tape  511  which is wound in a roll shape. That is, the adhesive film  512  constitutes a second end surface  51   b  (refer to  FIG. 6 ) which 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 which has a slightly longer outer diameter than that of the roll body  51  in an unused state. When the tape roll  5  is handled in a manufacturing process of the tape cartridge A, looseness of the roll body  51  is suppressed because of the adhesive film  512 . Moreover, the adhesive film  512  is translucent. 
     The tape core  52  is provided with a core portion  521  and a spacer portion  522 . The tape  511  is wound in a roll shape in the core portion  521 . 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 in an end portion on the −Z side of the core shaft  1112 . That is, the spacer portion  522  is provided between a first end surface  51   a  (with reference to  FIG. 6 ) which is an end surface on the −Z side of the roll body  51  and the first facing wall portion  111 . The spacer portion  522  is formed in a substantially annular plate shape in a hollow having a lightly longer outer diameter than that of the roll body  51  in an unused state. 
     With reference to  FIG. 6 , a relationship of a thickness of the spacer portion  522  and a width of the tape  511  will be described. Regarding the thickness of the spacer portion  522 , that is, a size in the tape width direction, a position of the center of the tape  511  (hereinafter, referred to as a “tape center”) in the tape width direction is set to be common to the plurality of types of tape cartridges A. Moreover, a dash-dotted line  511   p  indicates the position of the tape center in the Z direction. Therefore, the thin spacer portion  522  is used in the tape cartridge A in which the tape  511  having a wide width is accommodated, and the thick spacer portion  522  is used in the tape cartridge A in which the tape  511  having a narrow width is accommodated. Moreover, the spacer portion  522  may be omitted in the tape cartridge A in which the tape  511  having the widest width is accommodated. 
     With reference to  FIG. 7 , the spring member  6  will be described. The spring member  6  is provided between the second end surface  51   b  of the roll body  51  and the second facing wall portion  121  facing the second end surface  51   b . The spring member  6  urges the roll body  51  to the first end surface  51   a  side (−Z side). The spring member  6  is a translucent resin molded product. The spring member  6  is provided with a plate portion  61  and a plurality of (here, three) spring portions  62 . 
     The plate portion  61  is in contact with the second end surface  51   b  of the roll body  51 . The plate portion  61  is formed in a substantially thin annular plate shape having a slightly longer outer diameter than that of the roll body  51  in an unused state. In the plate portion  61 , an arc shape spring opening  611  which is one size greater than the spring portion  62  seen from the +Z side is provided at a position corresponding to the spring portion  62 . In addition, a circular opening  612  is provided at the substantially center of the plate portion  61 . The core portion  521  is inserted into the circular opening  612 . 
     The three spring portions  62  are dispersed at equal angular intervals in a circumferential direction of the plate portion  61 , and are provided in the plate portion  61 . The spring portion  62  is formed in an arc shape seen from the +Z side, and is formed to stand up in an inclined shape on the +Z side from the plate portion  61 . A continuous portion  621  corresponding to a base end of the spring portion  62  is connected to the plate portion  61  on one end of the spring opening  611  in a longitudinal direction. In addition, a contact portion  622  corresponding to a distal end of the spring portion  62  is in contact with the second facing wall portion  121 . The continuous portion  621  is positioned behind in a clockwise direction, that is, a rear side of the tape roll  5  in rotating direction seen from the +Z side. In addition, the contact portion  622  is positioned ahead in the clockwise direction, that is, ahead the tape roll  5  in a rotating direction seen from the +Z side. 
     The spring portion  62  is bendable, and an amount of deflection varies depending on being wide and narrow of a gap between the roll body  51  and the second facing wall portion  121 . That is, the tape cartridge A in which the tape  511  having a wide width is accommodated has a narrow gap between the roll body  51  and the second facing wall portion  121 , and thus the amount of deflection of the spring portion  62  is increased. Meanwhile, in the tape cartridge A in which the tape  511  having a narrow width is accommodated, the gap between the roll body  51  and the second facing wall portion  121  is wide, and thus the amount of deflection of the spring portion  62  is reduced. Therefore, the spring member  6  is capable of urging the roll body  51  regardless of the width of the tape  511 . 
     However, when the tape roll  5 , from which the tape  511  is fed out, is rotated, the spring member  6  is also rotated due to friction between the second end surface  51   b  of the roll body  51  and a surface on the −Z side of the plate portion  61  of the spring member  6 . 
     With reference to  FIGS. 8 and 9 , in the tape cartridge B according to another embodiment different from the tape cartridge A illustrated in  FIG. 3 , an aspect of the spring member  6  when the tape  511  is fed out from the roll body  51  will be described. The tape cartridge B is configured substantially in the same manner as the tape cartridge A, but it is different from in that the continuous portion  621  of the spring portion  62  is positioned ahead in the rotating direction of the tape roll  5 , and the contact portion  622  is positioned behind the tape roll  5  in the spring member  6  in the rotating direction. In this case, during rotating of the tape roll  5 , the spring member  6  is also continuously rotated, and the contact portion  622  intermittently generates sound, which is generated by the contact with the cartridge case  1 . Because, in this case, when the spring member  6  is rotated, the spring portion  62  is in contact with the rib  1212  at a position between the continuous portion  621  and the contact portion  622 , and becomes in a state of being deflected on the −Z side (refer to  FIG. 8 ). It is because, from this state, when the spring member  6  is further rotated, the contact portion  622  passes through the rib  1212 , and the contact portion  622  passed through the rib  1212  comes into contact with the second facing wall portion  121  again due to a spring force of the spring portion  62  (refer to  FIG. 9 ). 
     With respect to that, in the tape cartridge A, during rotating of the tape roll  5 , continuously rotating of the spring member  6  is suppressed, and thus generation of sound of the contact portion  622 , which is generated by the contact with the cartridge case  1  is suppressed. Hereinafter, with reference to  FIGS. 10 and 11 , in the tape cartridge A according to the embodiment, an aspect of the spring member  6  at the time of feeding out the tape  511  from the roll body  51  will be described. 
       FIG. 10  illustrates a state in which 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 be rotated in a clockwise direction seen from the +Z side, and consequently, the spring member  6  also starts to be rotated in the clockwise direction seen 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 in a rotating direction of the tape roll  5 , and the continuous portion  621  is positioned behind in the rotating direction of the tape roll  5 . Therefore, when the spring member  6  starts to be rotated, as illustrated in  FIG. 11 , the contact portion  622  of the spring portion  62  abuts to a side surface of the rib  1212  of the second case  12 . Accordingly, after the spring member  6  stops to be rotated, the tape roll  5  is rotated while being in slidably contact between the plate portion  61  of the stopped spring member  6  and the tape roll. In this way, generation of the sound of the contact portion  622 , which is generated by the contact with the cartridge case  1  is suppressed. 
     With reference to  FIGS. 12 and 13 , a position relationship of the tape  511  and the printing head  106  accommodated in a tape cartridge C according to a comparative example will be described. The tape cartridge C of the comparative example, unlike the tape cartridge A according to the embodiment, is provided with the cartridge case  1  having a varying size in the tape width direction depending on the width of the tape  511  so as to prevent the generation of a gap between the cartridge case  1  and the tape  511  in the tape width direction as much as possible. In addition, in the same manner as that of the tape cartridge A of the embodiment, the tape cartridge C is mounted with reference to the first facing wall portion  111 . Therefore, when the tape cartridge C is mounted in the cartridge mounting portion  104 , the tape center is deviated from the center of head depending on the types of the tape cartridge C. For example, as illustrated in  FIG. 12 , in the tape cartridge C in which the tape  511  having a wide width is accommodated, the tape center is positioned at the center of head, but as illustrated in  FIG. 13 , in the tape cartridge C in which the tape  511  having a narrow width is accommodated, the tape center is deviated from the center of head. Moreover, the dash-dotted line  106   p  illustrated in drawings indicates a position of the center of the head in the Z direction. Also, in the tape cartridge C in which the tape center is deviated from the center of head, the tape  511  is uniformly pressed by the printing head  106  in the tape width direction, a printing quality is deteriorated. 
     With respect to that, in this embodiment, in the plurality of types of the tape cartridges A in which widths of the tapes  511  are different, good printing can be performed regardless of the types of the tape cartridge A. Hereinafter, with reference to  FIGS. 14 and 15 , the position relationship of the tape  511  and the printing head  106  accommodated in the tape cartridge A of the embodiment will be described. 
     As illustrated in  FIGS. 14 and 15 , in the tape cartridge A of the embodiment, as described above, the plurality of types of tape cartridges A in which widths of the tapes  511  are different are provided with the cartridge case  1  common to the plurality of types of tape cartridges A. In addition, a thickness of the spacer portion  522  is different depending on the types of the tape cartridge A, and a position of the tape center is common to the plurality of types of tape cartridges A. Therefore, when the tape cartridge A is mounted in the cartridge mounting portion  104 , even in any type of the tape cartridge A, the tape center is positioned at the center of the head. As a result, even in any type of the tape cartridge A, since the tape  511  is uniformly pressed by the printing head  106  in the tape width direction, a good result can be obtained. 
     As seen from the above, the tape cartridge A of the embodiment in the plurality of types of tape cartridges A in which widths of the tape  511  are different is one of the tape cartridges A among the plurality of types of the tape cartridge A which are selectively mounted in the common tape printing device P. The tape cartridge A is provided with the roll body  51  around which the tape  511  is wound in a roll shape, the cartridge case  1  in which the roll body  51  is accommodated, the spacer portion  522  provided between the cartridge case  1  and the first end surface  51   a  of the roll body  51 , and the spring member  6  provided the cartridge case  1  and the second end surface  51   b  of the roll body  51 . The cartridge case  1  is common to the plurality of types of the tape cartridges A. The spacer portion  522  has a varying size depending on the type of the tape cartridge A in the tape width direction such that a position of the tape center of the tape  511  is common to the plurality of types of the tape cartridges A in the tape width direction. The spring member  6  urges the roll body  51  to the first end surface  51   a  side. 
     According to this configuration, as described above, in the plurality of types of the tape cartridges A in which the widths of the tape  511  are different, good printing can be performed regardless of the types of the tape cartridges A. 
     In addition, in the tape cartridge A of the embodiment, the spring member  6  is provided with the plate portion  61  and the spring portion  62 . The plate portion  61  is in contact with the second end surface  51   b  of the roll body  51 . The spring portion  62  is provided with the continuous portion  621  which is continuous to the plate portion  61 , and the contact portion  622  in contact with the cartridge case  1 . 
     In this configuration, the spring portion  62  urges the roll body  51  with a surface through the plate portion  61  in contact with the second end surface  51   b . Therefore, according to the configuration, it is possible to urge the roll body  51  in good balance without increasing the number of components. 
     In addition, in the tape cartridge A of the embodiment, the cartridge case  1  includes the rib  1212  which is provided in the second facing wall portion  121  facing the second end surface  51   b . The roll body  51  is rotated when the tape  511  is fed out. The continuous portion  621  is positioned behind in the rotating direction of the roll body  51 , and the contact portion  622  is positioned ahead in the rotating direction of the roll body  51 . 
     According to this configuration, as described above, when the tape  511  is fed out, rotation of the spring member  6  is suppressed, and generation of the sound of the contact portion  622 , which is generated by the contact with the cartridge case  1  is suppressed. 
     In addition, in the tape cartridge A of the embodiment, the spring member  6  includes a plurality of the spring portions  62 , and the plurality of spring portions  62  are dispersed in the circumferential direction of the plate portion  61  and is provided in the plate portion  61 . 
     According to this configuration, it is possible to urge the roll body  51  in good balance by the spring member  6 . 
     In addition, in the tape cartridge A of the embodiment, the second facing wall portion  121  facing the second end surface  51   b  in the cartridge case  1  and the spring member  6  are translucent. 
     According to this configuration, through the second facing wall portion  121  and the spring member  6 , an amount of remaining of the tape  511  in the roll body  51  can be visually recognized. 
     In addition, in the tape cartridge A of the embodiment, the spring member  6  is common to the plurality of types of the tape cartridges A. 
     According to this configuration, since it is unnecessary to prepare a plurality of types of the spring member  6 , increase in costs required for the spring member  6  can be suppressed. 
     The invention is not limited to the above-described embodiments, and it is needless to say that various configurations can be adopted without departing from the gist thereof. For example, the embodiment can be modified as follows. 
     The spring member  6  may be made of materials other than a translucent resin, and for example, a non-translucent resin, a metal such as stainless steel, and the like can be used. Moreover, in a case in which the spring member  6  is non-translucent, it is preferable that an opening be provided at a position deviated from the spring portion  62  in the plate portion  61  in order to be able to confirm the amount of remaining of the tape  511 . A shape of the plate portion  61  does not need to be flat, and for example, a shape in which the outer edge portion or an inner edge portion may be reversed toward the second facing wall portion  121  side. 
     As an urging member, it is not limited to the spring member  6 , and for example, an urging member made of an elastic material such as a sponge or a rubber may be used, or a compressing coil spring may be used.
