Description

[Detailed Description of the Invention] The present invention relates to a multicolor ink ribbon cartridge that stores ink ribbons divided into a plurality of colors in the width direction.

Conventionally, an ink ribbon 1 that is divided into multiple colors in the width direction is formed by forming multiple colors on a single woven fabric as shown in FIG. Since the ink ribbons are arranged parallel to the direction, the width of each color ink ribbon becomes extremely narrow.

Moreover, since the ink ribbon is stored in an endless ink ribbon cartridge, the total length of the ink ribbon is short and the lifespan of the ink ribbon is short.In addition, the width of the ink ribbon becomes wide due to multiple colors, which has the disadvantage of making replacement work troublesome. Ta.

The purpose of the present invention is to extend the life of the ink ribbon and to facilitate its replacement work, which will be explained in detail below using examples.

FIG. 2 is a partially cutaway perspective view showing an embodiment of the multicolor ink ribbon cartridge according to the present invention.

In the figure, 3 is a cartridge main body, and a front side cover (not shown) and a back side cover 4 are detachably provided.

5 is a partition plate provided on this cartridge body 3;
A storage section consisting of the partition plate 5, the side surface of the cartridge body 3, and a front side lid (not shown) is referred to as a first ink ribbon storage chamber 6. The storage section constituted by the above is referred to as a second ink ribbon storage chamber 7.

Reference numeral 8 designates first ink ribbons of colors that are frequently used for printing stored in the first ink ribbon storage chamber 6, and in this embodiment, two ink ribbons are used.

Reference numeral 9 denotes a second ink ribbon of a color that is less frequently used for printing, which is stored in the second ink ribbon storage chamber 7, and three colors are shown in the embodiment.

10 and 11 are feeding rollers and pressing rollers for feeding the first ink ribbon 8 and second ink ribbon 9 inside, and 12a to 12e are rollers for each of the stored ink ribbons of a plurality of colors, for example, five colors. This is a light emitting diode that emits the same color as the color or a color similar to the color, and indicates the print color by lighting the light emitting diode of the same color as the print color of the selected ink ribbon.

-13 is a leaf spring for smoothing out the first ink ribbon 8 and the second ink ribbon 9.

With this configuration, when the feeding roller 10 is rotated in the direction of the arrow by a drive source (not shown), the first ink ribbon 8 and the second ink ribbon 9 are moved toward the pressure roller 1.
Since the feeding rollers 10 are pressed by the rollers 1, they are fed into the first ink ribbon storage chamber 6 and the second ink ribbon storage chamber 7, respectively, and are sequentially fed out from the outlet.

If the first ink ribbon 8 is frequently used for printing and is worn out during work, the front cover (not shown) is removed and replaced with a new ink ribbon.

Furthermore, when the second ink ribbon 9 is worn out, the back cover 4 is removed and replaced with a new ink ribbon.

Although the above example shows the case where the partition plate 3 is provided integrally with the cartridge body 1, it goes without saying that the back cover 2 may be provided integrally with the cartridge main body 1 and the partition plate 3 may be made detachable. .

Further, although the ribbon width of each color of the first ink ribbon 6 or the second ink ribbon 7 is made the same, it may be made wider if printing is frequently used, and multiple ink ribbons of the same color may be provided. It is of course possible to do so.

In addition, in order to indicate to the operator the selected ink ribbon color, five light emitting diodes were provided when there were five ink ribbon colors, but it goes without saying that there is no limit to this number. It goes without saying that a normal colorless lamp may be used as the element and a colored cap may be used to display the display in color, or colored ink or paint may be provided to light up the display element at the corresponding position.

As described above in detail, the multicolor ink ribbon cartridge according to the present invention has the effect that multicolor ink ribbons can be used efficiently.
