Abstract

(57) [Abstract] [Purpose] It is an object to provide an ink ribbon cassette that improves the running stability of a paper in a dot impact printer. [Structure] Ribbon guides 2 and 2 are provided on both sides of an ink ribbon storage unit 1, and a paper guide unit is integrally installed at a tip end thereof.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an ink ribbon cassette used in a dot impact printer.

[0002]

[Prior Art]

 A conventional technique of this type is shown in FIG. In the figure, 1 is an ink ribbon storage part, 2 and 2 are ribbon guide parts, and 4 is an ink ribbon. The ink ribbon 4 in the ink ribbon storage unit 1 is guided by one of the ribbon guides 2, passes through a printing space, is guided by the other ribbon guide 2, and returns to the ink ribbon storage unit 1.

[0003]

[Problems to be solved by the device]

 When the above conventional ribbon cassette is mounted on the printer, it becomes as shown in FIG. In the figure, 1 is an ink ribbon storage portion, 2 is a ribbon guide portion, 4 is an ink ribbon, 5 is a platen, 6 is a sheet guide on the platen side, 7 is a tractor, 8 is a print head, and 9 is a sheet. In this ribbon cassette, a space H for passing the ink ribbon 4 when inserting the ink ribbon 4 between the print head 8 and the tractor 7 was required. Therefore, between the time when the paper 9 passes the print head 8 and the time when it enters the tractor 7, there is no guide for the paper 9 on at least one side, which adversely affects the print quality and the running of the paper 9. It was In order to solve the above-mentioned problems, some printers are equipped with a paper guide 10 which is a separate component that enters the space H after the movable ink ribbon is attached as shown by the broken line in FIG. However, this was a factor of cost increase due to the complicated mechanism. In order to solve the above problems, the present invention aims to provide a low-cost printer while stabilizing the running of the paper by attaching a paper guide integrated with the ink ribbon guide to the ribbon cassette. It is a thing.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention has the following configuration. In other words, a paper guide portion that enters the space H is integrally provided above the tip of the ribbon guide portion.

[Action]

 The paper guide unit integrated with the ribbon guide unit of the ribbon cassette enters the space H formed between the print head and the tractor when the ribbon cassette is mounted, and stabilizes the running of the paper.

[0005]

【Example】

 FIG. 1 shows a first embodiment of the present invention, wherein 1 is an ink ribbon storage portion, 2 and 2 are ribbon guide portions, 3 is a paper guide portion, 4 is an ink ribbon, and the paper guide portion 3 is a ribbon guide portion. It is integrally installed on the upper ends of the parts 2 and 2, and as shown in FIG. 2, the paper guide part 3 is inserted in the space H between the print head 8 and the tractor 7 to mount the paper on the printer so that the paper can run. Stabilize. FIG. 3 shows a second embodiment of the present invention in which the ribbon storage part 1, the ribbon guide parts 2 ', 2', and the paper guide part 3 are separated, and the ribbon cassette mounting part and the print head are shown. There is an advantage that the size of the ribbon cassette can be reduced when 8 is separated.

[0006]

[Effect of the device]

 As described above, according to the present invention, when the ribbon cassette 1 is mounted, the paper guide portion 3 is inserted into the space H between the print head 8 and the tractor 7, so that a stable paper is obtained. This is effective in that it can achieve high-quality running and, in turn, improve printing quality. In addition, since it is not necessary to attach special parts to the printer, the cost of the printer is not increased, and a low-cost printer can be realized.
