Abstract

A printing cassette includes: a case including a first case portion, a second case portion, and a third case portion; a first tape, at least a portion of which is accommodated in the third case portion; and a gear, a portion of which is accommodated in the second case portion and the other portion of which is located outside of the case, the gear being rotatable about a rotation axis parallel to a first direction. The first case portion has an outlet through which the first tape is discharged. The first case portion, the second case portion, and the third case portion are disposed in an order of the first case portion, the second case portion, and the third case portion in the first direction.

First claim

What is claimed is:

1. A printing cassette comprising:
a case including a first case portion, a second case portion, and a third case portion;
a first tape, at least a portion of which is accommodated in the third case portion; and
a gear being partially exposed from the case, wherein:
the first case portion, the second case portion, and the third case portion are disposed in an order of the first case portion, the second case portion, and the third case portion in a first direction.

2. The printing cassette according to claim 1 , wherein:
the first case portion includes:
a protruding portion having a first surface defining a head opening; and
a facing portion defining the head opening, the facing portion having a second surface facing the first surface in a second direction orthogonal to the first direction, and

the second case portion has a third surface, the third surface being disposed at an end of the head opening in the first direction and connecting between the protruding portion and the facing portion.

3. The printing cassette according to claim 1 , wherein a volume of an internal space of the third case portion is greater than a volume of an internal space of the first case portion.

4. The printing cassette according to claim 1 , wherein a total weight of the third case portion and components accommodated in the third case portion is greater than a total weight of the first case portion and components accommodated in the first case portion.

5. The printing cassette according to claim 1 , wherein:
the first case portion and the second case portion are separated by a first separation wall, and
the second case portion and the third case portion are separated by a second separation wall.

6. The printing cassette according to claim 1 , further comprising:
a first cover portion;
a first frame portion connected to the first cover portion in the first direction;
a second frame portion connected to the first frame portion in the first direction; and
a second cover portion connected to the second frame portion in the first direction, wherein:
the first case portion includes the first cover portion and a first portion of the first frame portion in the first direction,
the second case portion includes a second portion of the first frame portion and a third portion of the second frame portion in the first direction, the second portion being a side opposite to the third direction in the first direction, and
the third case portion includes a fourth portion of the second frame portion and the second cover portion, the fourth portion being a side opposite to the third portion in the first direction.

7. The printing cassette according to claim 6 , wherein a dimension of the second frame portion in the first direction is greater than a dimension of the first frame portion in the first direction.

8. The printing cassette according to claim 6 , wherein the gear is disposed between claws connecting between the first frame portion and the second frame portion.

9. The printing cassette according to claim 1 , wherein a dimension of the first case portion in the first direction and a dimension of the third case portion in the first direction are greater than a dimension of the second case portion in the first direction.

10. The printing cassette according to claim 9 , wherein the dimension of the first case portion in the first direction is equal to or greater than the dimension of the third case portion in the first direction.

11. The printing cassette according to claim 1 , further comprising:
a second tape; and
a roller that lays the second tape over the first tape, wherein:
at least a portion of the first tape, at least a portion of the second tape, and at least a portion of the roller are arranged next to each other in the first direction and accommodated in the first case portion, and
the roller is supported by the second case portion such that at least a portion of the roller overlaps the second case portion in a direction orthogonal to the first direction.

12. The printing cassette according to claim 1 , further comprising a restricting portion that restricts movement of the first tape in a width direction of the first tape,
wherein the first case portion has an outlet through which the first tape is discharged, and
wherein the restricting portion is disposed between ends of the outlet in the width direction of the first tape.

13. The printing cassette according to claim 1 , further comprising:
a roll for the first tape; and
a restricting portion that restricts movement of the first tape in a width direction of the first tape, wherein:
the roll is accommodated in the third case portion, and
the restricting portion is disposed between ends of the roll in the width direction of the first tape.

14. The printing cassette according to claim 1 , further comprising a roll for the first tape, wherein:
the first case portion has an outlet through which the first tape is discharged,
the roll is accommodated in the third case portion, and
the first tape drawn from the roll is discharged from the outlet via the second case portion and the first case portion.

15. The printing cassette according to claim 14 , wherein the second case portion includes a partition wall that separates a space in which the gear is disposed and a space through which the first tape travels.

16. The printing cassette according to claim 1 , further comprising an ink ribbon, wherein:
at least a portion of the ink ribbon is accommodated in the first case portion,
the first case portion has an outlet for opening through which the first tape is discharged to a head opening, and
the ink ribbon is to be laid over the first tape discharged from the outlet for opening.

17. A printer comprising:
the printing cassette according to claim 1 ; and
a printer body on which the printing cassette is to be mounted,
wherein the printer body includes a driving force transmission portion to be engaged with the gear.

18. A printing cassette comprising:
a case;
a first tape roll, at least a portion of which is accommodated in the case and into which a first tape is wound; and
a gear, at least a portion of which is accommodated in the case, wherein:
the case has an outlet through which the first tape is discharged; and
the outlet, the gear, and the first tape roll are disposed in an order of the outlet, the gear, and the first tape in a first direction.

19. A printing cassette comprising:
a case;
a first tape roll, at least a portion of which is accommodated in the case and into which a first tape is wound; and
a gear, at least a portion of which is accommodated in the case, wherein:
the case has a head opening, and
the head opening, the gear, and the first tape roll are disposed in an order of the head opening, the gear, and the first tape in a first direction.
