Abstract

(57) [Abstract] [Purpose] In a printer using a plurality of types of ink ribbons, a single detector detects three or more types of ink ribbons. [Structure] A pattern 10 composed of white and black is provided on the surface of a holding portion 9 of an ink ribbon 1, and a detector 11 is provided at a position facing the pattern 10 when a cartridge 2 is mounted in a printer device. As a result, the single detector 11 detects the pattern 10 set according to the type of the ink ribbon 1, and identifies a plurality of types of the ink ribbon.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a printer device, and more particularly to a printer device that uses a plurality of types of ink ribbons.

[0002]

[Prior Art]

 As shown in FIG. 2 (a), a conventional printer device has a cartridge 2 for accommodating an ink ribbon 1 provided with a plate 3 according to the type of the ink ribbon 1, and as shown in FIG. 2 (b), a plate 3 is provided. Some do not have.

Further, the mounting portion of the cartridge 2 has a detector 4 for detecting the plate 3. The detector 4 detects the presence of the plate 3 when the printer is operated with the cartridge 2 mounted. Upon receiving the detection information of the plate 3, the printer device identifies whether the cartridge 2 is the type A or the type B. For the type A ink ribbon 1, the detector 4 detects the end of the plate 3 when switching the print tracks 5, 6, 7, and 8, and the end position is used as the origin. Print Tracks 6 to 8 are positioned.

[0004]

[Problems to be solved by the device]

 In such a conventional printer device, only the type of ink ribbon can be identified depending on the presence or absence of the shape provided on the cartridge, and a plurality of detectors are required to identify three or more types. There is a problem that is.

Further, in the positioning operation at the time of switching the print tracks, the origin is detected at a position apart from the ink ribbon, so that it is difficult to secure the positioning accuracy of the print tracks.

An object of the present invention is to provide a printer device that detects three or more types of ink ribbons using a single detector.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, in the printer device according to the present invention, the end portion of the cartridge for storing the ink ribbon or the ink ribbon is mounted in the printer device in which a plurality of types of ink ribbons are exchanged for use. There are two types of markings with different light reflectance on the surface of the ink ribbon holding part provided near the print head of the printer device, and the marking is detected near the print head of the printer device where the ink ribbon is mounted. It has a detector that does.

In addition, the surface of the holding portion of the ink ribbon has two kinds of markings having different light reflectances and indicating the print track position of the ink ribbon.

In addition, a plate with slits is provided as a marking, and a transmissive photosensor is provided as a detector.

[0010]

[Action]

 A single detector detects the pattern set according to the ink ribbon type, and identifies multiple ink ribbon types. Also, the print track position is detected by setting the pattern so as to correspond to each of the multiple print tracks on the ink ribbon. The type of the ink ribbon is identified by detecting the slit provided on the plate on the cartridge according to the type of the ink ribbon by the detector.

[0011]

【Example】

 Next, the present invention will be described with reference to the drawings. FIG. 1 is an external view of a printer device according to an embodiment of the present invention. FIG. 1 (a) shows an embodiment in which the ink ribbon holding portion is on the cartridge side, and FIG. 1 (b) shows an embodiment in which the ink ribbon holding portion is mounted near the print head for use. Here is an example. Further, FIG. 1C shows an embodiment using a plate with slits.

In the figure, on the surface of the holding portion 9 of the ink ribbon 1 in the cartridge 2 containing the ink ribbon 1, a strip-shaped pattern 10 composed of white with high light reflectance and black with low light reflectance is formed. Set up. On the other hand, in the printer device, the detector 11 is provided at a position facing the pattern 10 when the cartridge 2 is mounted.

The detector 11 detects the pattern 10 to identify the type of the ink ribbon 1 contained in the mounted cartridge 2. When the print tracks 5, 6, 7 and 8 are present on the ink ribbon 1 and the print tracks are switched, the print track positioning is performed while the detector 11 detects the pattern 10 indicating each print track position. I do.

In FIG. 1C, the plate 3 provided on the cartridge 2 has a slit 12. The detector 4 identifies the type of the ink ribbon 1 accommodated in the cartridge 2 by detecting the slit 12 on the plate 3.

[0015]

[Effect of the device]

 As described above, according to the present invention, the ink ribbon type is identified by the specific pattern displayed on the ink ribbon holding portion or the slit of the plate provided on the cartridge. It has the result that it can be identified using a vessel.

Further, in the positioning of the print track, the positioning operation is performed while detecting the specific pattern displayed on the holding portion of the ink ribbon, so that the print track can be positioned with high accuracy.
