[Change of state of first torque switching mechanism]

When the first tape cartridge 101a is mounted in the cartridge mounting portion 2, as described above, the cartridge-side first engaging portion 124a and the cartridge-side second engaging portion 124b are, respectively, the apparatus-side first engaging portions, respectively. (49a) and the device-side second engaging portion 49b (see Fig. 15).

At this time, the cartridge-side first engaging portion 124a is engaged with the device-side first engaging portion 49a in the order of the first engaging inclined surface 54 and the first operating surface 55 . Thereby, the apparatus side 1st engaging part 49a is pressed to the +X side. As a result, from the state shown in FIG. 22, the 1st switching actuator 47a resists the elastic force of the actuator spring 56 and rotates counterclockwise as shown in FIG. At this time, since the first operator-side engaging portion 52 of the first switching actuator 47a moves to the +X side, the first operator-side engaging portion 52 on the -X side of the first operator-side engaging portion 52 . ) and the first engaging portion 67 on the side of the supporting portion engaged with the unit is movable to the +X side. Thereby, the first operator-side support member 63 moves in a counterclockwise direction, that is, in a direction in which the movable gear 46 supported by the first operator-side support member 63 approaches the first take-up gear 41 . can be rotated with In this way, when the cartridge-side first engagement portion 124a engages with the device-side first engagement portion 49a, the first switching operator 47a rotates counterclockwise to support the first operator side. Allow the member 63 to rotate counterclockwise.

Further, the cartridge-side second engaging portion 124b is engaged with the device-side second engaging portion 49b in the order of the second engaging inclined surface 61 and the second operating surface 62 . Thereby, the apparatus side 2nd engaging part 49b is pressed to the -X side. As a result, as shown in FIG. 21, from the state shown in FIG. 22, the 2nd switching operator 47b rotates counterclockwise. At this time, in order for the second operator-side engaging portion 58 of the second switching actuator 47b to press the support-side second engaging portion 69 of the second operator-side supporting member 64 to the -X side, The second operator-side support member 64 rotates counterclockwise. When the second operator-side support member 64 rotates counterclockwise, the first operator-side support member 63 resiliently connected to the second operator-side support member 64 via the support spring 65 is turned halfway. Clockwise, that is, the movable gear 46 supported by the first operator-side support member 63 rotates in a direction closer to the first take-up gear 41 . As a result, as shown in FIG. 6 , the movable gear 46 meshes with the first take-up gear 41 . In this way, the second switching operator 47b rotates counterclockwise when the cartridge-side second engagement portion 124b engages the device-side second engagement portion 49b, whereby the first operator-side support member (63) is rotated counterclockwise.

Here, the first operator-side support member 63 and the second operator-side support member 64 are elastically connected by a support spring 65 . For this reason, in the state shown in FIG. 22, the second operator-side support member 64 rotates counterclockwise by the engagement rotation amount θ, and after the movable gear 46 meshes with the first take-up gear 41 , with respect to the first actuator-side support member 63 , it can be rotated by the additional rotation amount α in the counterclockwise direction by resisting the elastic force of the support spring 65 . Here, the engagement rotation amount θ means the minimum value of the rotation amount of the second operator-side support member 64 required for the movable gear 46 to mesh with the first take-up gear 41 . For this reason, if the rotation amount of the second operator-side support member 64 is greater than or equal to the engagement rotation amount θ and less than or equal to the sum of the engagement rotation amount θ and the additional rotation amount α (θ+α), the movable gear 46 is It is pressed against the first winding gear 41 . Accordingly, the design value of the rotation amount of the second operator-side supporting member 64 may be set to be larger than θ and smaller than (θ+α). Accordingly, even if the amount of rotation of the second operator-side support member 64 varies due to a dimensional deviation of the cartridge-side second engaging portion 124b or the like, if the value is θ or more (θ+α) or less, the movable gear 46 ) can be properly engaged with the first winding gear 41 . That is, the dimensional deviation of the cartridge-side second engaging portion 124b and the like can be absorbed by the support spring 65 .

In this way, when the first tape cartridge 101a is mounted on the cartridge mounting portion 2, the cartridge-side first engaging portion 124a and the cartridge-side second engaging portion 124b are respectively connected to the apparatus-side first engaging portion ( 49a) and the device-side second engaging portion 49b. Thereby, the gear support part 48 rotates counterclockwise, and the movable gear 46 meshes with the 1st take-up gear 41. As shown in FIG. As a result, the first torque switching mechanism 31 transmits the state in which the rotation of the feed motor 20 is inputted to the first take-up gear 41 via the movable gear 46 , that is, to the first take-up rotor 16 . The state is changed to the first state in which the torque to be used is the first torque.

Next, the state change of the first torque switching mechanism 31 when the first tape cartridge 101a is removed will be described. When the first tape cartridge 101a is detached from the cartridge mounting portion 2, as described above, the cartridge-side first engaging portion 124a and the cartridge-side second engaging portion 124b are respectively connected to the apparatus-side first engagement portion 124b. It comes off from the engaging part 49a and the apparatus side 2nd engaging part 49b.

When the engagement of the cartridge-side first engaging portion 124a and the device-side first engaging portion 49a is released, from the state shown in Fig. 21, as shown in Fig. 22, the first switching operator 47a By the elastic force of the actuator spring 56, it rotates clockwise. As a result, the first operator-side engaging portion 52 of the first switching actuator 47a urges the support-side first engaging portion 67 of the first operator-side supporting member 63 to the -X side. For this reason, the first operator-side support member 63 rotates clockwise, that is, the movable gear 46 supported by the first operator-side support member 63 rotates in a direction away from the first take-up gear 41 . . As a result, as shown in FIG. 7 , the movable gear 46 is pulled out from the first take-up gear 41 . In this way, the first switching actuator 47a rotates clockwise when the cartridge-side first engaging portion 124a is disengaged from the apparatus-side first engaging portion 49a, and thereby the first operator-side supporting member 63 ) is rotated clockwise to prevent the first operator-side supporting member 63 from rotating counterclockwise.

When the first operator-side support member 63 rotates clockwise, the second operator-side support member 64 resiliently connected to the first operator-side support member 63 via the support spring 65 moves in the clockwise direction. rotate to As a result, the support-side second engagement portion 69 of the second operator-side support member 64 urges the second operator-side engagement portion 58 of the second switching actuator 47b to the +X side. At this time, as described above, by disengaging the engagement between the cartridge-side second engaging portion 124b and the device-side second engaging portion 49b, the device-side second engaging portion 49b can be moved to the +X side, That is, the 2nd switching operator 47b is rotatable clockwise. For this reason, the 2nd switching actuator 47b is pressed by the 2nd actuator side support member 64, and it rotates clockwise.

In this way, when the first tape cartridge 101a is detached from the cartridge mounting portion 2, the cartridge-side first engaging portion 124a and the cartridge-side second engaging portion 124b are respectively connected to the apparatus-side first engaging portion ( 49a) and the device-side second engaging portion 49b. Thereby, the gear support part 48 rotates clockwise, and the movable gear 46 comes off from the 1st take-up gear 41. As shown in FIG. As a result, the first torque switching mechanism 31 is in a state in which the rotation of the feed motor 20 is inputted to the first take-up gear 41 via the second take-up gear 42 , that is, the first take-up rotor 16 . The state is changed to a second state in which the torque transmitted to the motor is used as the second torque.

Further, as described above, when the second tape cartridge 101b is mounted on the cartridge mounting portion 2, the connection convex portion 119 and the connection concave portion 121 are respectively connected to the device-side first engagement portion 49a and It is not engaged with the device-side second engaging portion 49b (see Fig. 16). Therefore, when the second tape cartridge 101b is mounted on the cartridge mounting portion 2, the first torque switching mechanism 31 remains in the second state, and the torque transmitted to the first winding rotor 16 is 2 The torque remains the same.

As described above, according to the first tape cartridge 101a and the tape printing apparatus 1 of the present embodiment, when the first tape cartridge 101a is mounted in the cartridge mounting portion 2, the cartridge side first engaging portion 124a ) and the cartridge-side second engaging portion 124b are engaged with the device-side first engaging portion 49a and the device-side second engaging portion 49b, respectively, so that the first torque switching mechanism 31 is in the second state. state change from to the first state. Thereby, the torque transmitted to the 1st take-up rotor 16 is switched from the 2nd torque to the 1st torque. Therefore, compared with the case where the first winding rotor 16 has a double barrel structure, the diameter of the first winding core 105 can be made small, and the first tape cartridge 101a can be downsized. In addition, compared to the case where the first winding rotor 16 has a double barrel structure, the amount of backlash of the first winding rotor 16 with respect to the first winding shaft 11 is reduced. For this reason, since the center of the first winding core 105 and the center of the first winding shaft 11 can be approximately coincident, the first ink ribbon 109 can be appropriately wound around the first winding core 105 . have.

Further, according to the first tape cartridge 101a and the tape printing apparatus 1 of the present embodiment, the first tape cartridge 101a and the first torque switching mechanism 31 do not engage only at one location, but rather the cartridge. The side first engagement portion 124a and the device-side first engagement portion 49a are engaged at two places: the cartridge-side second engagement portion 124b and the device-side second engagement portion 49b. For this reason, the load due to engagement acts in a well-balanced manner with respect to the first tape cartridge 101a, so that the inclination of the first tape cartridge 101a with respect to the cartridge mounting portion 2 is suppressed, and the first printing tape ( 107) and the running properties of the first ink ribbon 109 can be improved.

Further, as in the present embodiment, the cartridge-side first engaging portion 124a and the cartridge-side second engaging portion 124b are not limited to a configuration arranged point-symmetrically with respect to the center of the core concave portion 115, respectively, , as long as it can engage with the device-side first engagement portion 49a and the device-side second engagement portion 49b. For example, the dimension between the center of the cartridge-side first engaging portion 124a and the core concave portion 115 and the dimension between the cartridge-side second engaging portion 124b and the center of the core concave portion 115 are different. may do Also, the cartridge side first engaging portion 124a, the center of the core recessed portion 115, and the cartridge side second engaging portion 124b are not arranged in a straight line as viewed from the inner side in the mounting direction. good. That is, the cartridge-side first engaging portion 124a and the cartridge-side second engaging portion 124b have a core concave within a range capable of engaging with the device-side first engaging portion 49a and the device-side second engaging portion 49b. What is necessary is just to face each other with the center of the part 115 interposed therebetween. Also, the shape of the cartridge-side first engaging portion 124a and the cartridge-side second engaging portion 124b, which are disposed oppositely with the center of the core concave portion 115 therebetween, as viewed from the inner side in the mounting direction, are different from each other. may do Similarly, it is not limited to the structure arrange|positioned symmetrically with respect to the center of the core convex part 5 also about the apparatus side 1st engagement part 49a and the apparatus side 2nd engagement part 49b. Further, the direction in which the device-side first engagement portion 49a is pressed by the cartridge-side first engagement portion 124a and the device-side second engagement portion 49b are pressed by the cartridge-side second engagement portion 124b. The directions are preferably opposite to each other.
