JPS6328688A - Ink ribbon device for printer - Google Patents

Abstract

PURPOSE:To utilize the entire area of an ink ribbon and to lengthen its service life, by arranging the ink ribbon in a manner that the longitudinal direction thereof is inclined by predetermined angle against the moving direction of a print head. CONSTITUTION:An ink ribbon 1 in a printer is fed out from an ink ribbon case 3 and taken-up, and arranged such that the longitudinal directions thereof made a predetermined angle theta with the moving direction T of a print head 2. Since the print head 2 moves within a range on the ink ribbon 1 surrounded by points (a)-(d) or moves on a locus 4 through the printing operation thereof, the entire lateral area of the ink ribbon 1 can be utilized. Consequently, the service life of the ink ribbon is lengthened and the number of replacing times of the ink ribbon can be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an ink ribbon device for a printer, and more particularly to an ink ribbon device for a serial printer in which a print head performs a printing operation while moving in the lateral direction.

[Conventional technology]

FIGS. 4(a) and 4(b) are a plan view and a front view showing the relationship between a conventional serial print ink ribbon device and a print head.

As shown in FIG. 4, the ink ribbon device of the conventional serial printer includes an ink ribbon 11 and a print head 12.
is placed parallel to the direction of motion.

Therefore, the print head 12 moves on this ink ribbon 11 while drawing a trajectory 14 (indicated by diagonal lines) as shown in FIG. 3 [Problems to be Solved by the Invention] As mentioned above, in the in-ribbon device of the conventional serial printer, the ink ribbon is arranged parallel to the moving direction of the print head. Since the entire width of the ink ribbon is not used, and only a portion of it is used, there is a problem that the life of the ink ribbon is short.

The problem to be solved by the present invention, in other words, the object of the present invention is to eliminate the drawbacks of the ink ribbon device of the conventional serial printer as described above, and to make it possible to use the entire area of the ink ribbon. [Means for Solving the Problems] The ink ribbon device for a printer of the present invention has the purpose of providing an ink ribbon device for a printer that has a longer service life. In the ink ribbon device of the printer, the ink ribbon is arranged such that the longitudinal direction of the ink ribbon is at a certain inclination angle with the moving direction of the print head.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

1(a) and (b) are a plan view and a front view showing an embodiment of the present invention, and FIG. 2 is a perspective view of the embodiment of FIG. 1.

As shown in FIGS. 1 and 2, the ink ribbon 1 of the printer is arranged so that its longitudinal direction forms a constant inclination angle (θ) with respect to the moving direction (arrow T) of the print head 2. There is. Therefore, by the printing operation of the print mode 1, the range surrounded by points a, b, c, and d on the ink ribbon 1 is moved.

FIG. 3 is an explanatory diagram showing a trajectory 4 in which the print head moves on the ink ribbon of the printer. As shown in FIG. Since the ink ribbon 1 moves in this manner, the entire width of the ink ribbon 1 can be used. Therefore, when an ink ribbon of the same width and length is used, it can be used on land for a longer period than before, and the life of the ink ribbon can be extended.

〔Effect of the invention〕

As explained above, by using the ink ribbon device of the printer of the present invention, there is an effect that the usable area of the ink ribbon can be increased and the single use period of the ink ribbon, that is, the life of the ink ribbon can be lengthened. Therefore, it has the effect of reducing the number of times the ink ribbon needs to be replaced8.
