Abstract

An ink ribbon is serially coated by inks in the three primary colors. A distinction portion is provided at each boundary portion between different colored inks. Each distinction portion is formed from two lines, one having a width common for all the distinction portions and regardless of corresponding ink color and one set with a width peculiar to particular ink color. Because this decreases the region taken up by the distinction portion, the printable region on the ink ribbon can be increased.

Claims

1. A tape cassette housing a tape that is fed in a tape feeding direction, comprising:

a cassette casing comprising upper and lower surfaces and a lateral surface extending between the upper and lower surfaces, a portion of each of the upper, lower, and lateral surfaces defining a head recess capable of accommodating a printing head support of a printing device; and

the upper, lower, and lateral surfaces further defining a first slot in the head recess extending in the tape feed direction and receiving a corresponding protrusion on the printing head support, the first slot having a first opening adjacent the upper surface and a second opening adjacent the lower surface.

2. The tape cassette of claim 1, further comprising a second slot formed in the head recess and oriented substantially perpendicular to the first slot.

3. The tape cassette of claim 2, wherein the second slot has a first opening adjacent the upper surface and a second opening adjacent the lower surface.

4. The tape cassette of claim 2, wherein the tape cassette is adapted for use in a printing device wherein the printing head support comprises a first surface supporting a thermal head and a second surface opposite the first surface, the second slot of the tape cassette facing the second surface of the printing head support.

5. The tape cassette of claim 1, wherein the first slot is formed in the lateral surface and extends from the upper surface to the lower surface.

6. The tape cassette of claim 1, wherein the head recess comprises a through-hole.

7. A tape cassette, comprising:

a cassette casing;

a head recess formed in the cassette casing, the head recess capable of accommodating a printing head support of a printing device; and

a first slot formed in the head recess and locating the tape cassette in a predetermined orientation relative to the printing head support.

8. The tape cassette of claim 7, wherein the first slot comprises a generally horizontally extending groove.

9. The tape cassette of claim 7, wherein the first slot is formed in a first wall of the head recess and a second slot is formed in a second wall of the head recess substantially perpendicular to the first wall.

10. The tape cassette of claim 7, wherein the cassette casing has upper and lower surfaces, and the first slot has a first opening adjacent the upper surface and a second opening adjacent the lower surface.

11. The tape cassette of claim 7, wherein the head recess comprises a through-hole.

12. A tape cassette mounting system, comprising:

a printing head support supporting a thermal printing head, the printing head support including first and second coupling ridges;

a cassette casing having a head recess formed therein for accommodating the printing head support, the cassette casing including a first slot formed in at least one wall defining the head recess, the first slot and head recess receiving the first and second coupling ridges of the printing head support.

13. The tape cassette mounting system of claim 12, wherein the first and second coupling ridges are formed on perpendicular walls of the printing head support.

14. The tape cassette mounting system of claim 12, wherein the cassette casing has upper and lower surfaces, and the first slot has a first opening adjacent the upper surface and a second opening adjacent the lower surface.

15. The tape cassette mounting system of claim 12, wherein the head recess comprises a through-hole.

16. A printing device, comprising:

a tape cassette mounting area having a base surface;

a printing head support extending upwardly from the base surface of the mounting area, the printing head support comprising a first surface supporting a thermal printing head, a second surface opposite to the first surface, a first coupling ridge on the second surface, and a second coupling ridge formed on the printing head support, the second coupling ridge positioned substantially perpendicular to the first coupling ridge on the second surface of the printing head support; and

a tape cassette comprising upper and lower surfaces and a lateral surface extending between the upper and lower surfaces, a portion of each of the upper, lower, and lateral surfaces defining a head recess receiving the printing head support and the coupling ridges to locate the tape cassette in a predetermined orientation relative to the printing head support, and a first slot in the head recess that is adapted to receive the second coupling ridge on the printing head support.

17. A tape cassette for use in a printing device having a tape cassette mounting area including a base surface, a printing head support extending upwardly from the base surface, the printing head support comprising a first surface supporting a thermal printing head, a second surface opposite to the first surface, a first coupling ridge on the second surface, and a second coupling ridge formed on the printing head support, the second coupling ridge positioned substantially perpendicular to first coupling ridge on the second surface of the printing head support, the tape cassette comprising:

a cassette casing comprising upper and lower surfaces and a lateral surface extending between the upper and lower surfaces;

a head recess formed in the cassette casing and interacting with the coupling ridges of the printing head support to locate the tape cassette in a predetermined orientation relative to the printing head support when the tape cassette is mounted in the mounting area, the head recess including a slot that is adapted to receive the second coupling ridge on the printing head support.
