Description

[Detailed description of the invention] The present invention relates to a wire dot color recorder, and more specifically, it is configured to record the magnitude of measured values in analog color dots and to record patterns in specific colors. The present invention relates to an improvement of a wire dot color recorder, and provides a wire dot color recorder that has a relatively simple configuration and is capable of high-speed recording.

FIG. 1 is a configuration explanatory diagram showing an example of the main parts of a conventional wire dot color recorder, in which 10 is an ink ribbon unit, 11 is an ink ribbon dyed in multiple colors in strips along the longitudinal direction, and 12 is an ink ribbon unit.
20 is a plurality of wire hammer units arranged along the moving direction of a carriage (not shown) to correspond to each color band of the ink ribbon 11; 21 is a wire hammer unit 20; A wire hammer, 22 a drive mechanism that selectively drives the wire hammer 21 according to a recording signal, 30 a recording paper, 40
is the platen. These ink ribbon unit 10 and wire hammer unit 20 are arranged such that the wire hammer 21 is connected to the recording paper 3 through the ink ribbon 11.
It is installed on the carriage so that it faces the.

In such a configuration, the carriage carries the recording paper 3.
Zero of the recording paper 30 in the direction perpendicular to the zero feeding direction. While reciprocating within the range including the span, it stops at a position according to the size of the recording signal. While the carriage is stopped, the wire hammer 21 is selectively driven in accordance with the recording signal, and the corresponding color band of the ink ribbon is pressed against the recording paper 30 to perform color dot recording. The ink ribbon 11 is a wire hammer 21
It is sent in fixed amounts according to the drive of the Recording paper 30
is normally fed by a fixed amount at the point when the carriage turns around, and is stopped until the carriage reaches the turning point.

FIG. 2 shows an ink ribbon 11 and a wire hammer 2 in such a wire dot color recorder.
1 is an explanatory diagram showing an example of the correspondence relationship with 1, in which wire hammers 21 ₁ to 21 ₆ are provided in each color band C ₁ to C ₆ of the ink ribbon 11 along the moving direction of the carriage shown by arrow A. It is being

However, according to such a configuration, for example, the third
To record the pattern "0" as shown in the figure, move the carriage seven times to the zero point on the recording paper 30. It is necessary to move the ink ribbon 11 and the recording paper 30 seven times in the range including the span, which takes a very long time, and high-speed recording of this type of pattern cannot be performed. .

The present invention solves these conventional drawbacks, and includes an ink ribbon dyed in multiple colors in strips along the length of the carriage, which moves back and forth in a direction perpendicular to the feeding direction of the recording paper. A first wire hammer unit group consisting of a plurality of wire hammer units arranged along the moving direction of the carriage to correspond to each color band of the ink ribbon, and a first wire hammer unit group to correspond to a specific color band of the ink ribbon. A second wire hammer unit group consisting of a plurality of wire hammer units arranged in a direction intersecting the moving direction of the carriage is provided to face the recording paper via an ink ribbon,
The present invention is characterized in that the drive mechanism for the first wire hammer unit group and the drive mechanism for the second wire hammer unit group are arranged in a stacked manner.

Hereinafter, it will be explained in detail using the drawings.

FIG. 4 is an explanatory diagram showing an example of the correspondence between the ink ribbon 11 and the wire hammer 21 in the present invention, and shows each color band C ₁ to _{C 6} of the ink ribbon 11.
1 along the carriage movement direction as before.
Wire hammers 21 ₁ to 21 ₆ are provided one by one, and a plurality of wire hammers 21 1 to 21 6 are provided in a specific color band (C ₄ in this embodiment) so as to be orthogonal to the moving direction A of the carriage (in this embodiment, wire hammers 21 1 to 21 ₆ are provided at the beginning). A total of six wire hammers 21 ₇ to 21 ₁₂ are provided. The ink ribbon 11 is arranged so as to move obliquely to the moving direction A of the carriage. The drive mechanisms 22 ₁ to 22 ₁₂ that selectively drive these wire hammers 21 ₁ to 21 ₁₂ have wire hammer units 20 ₁ to 20 ₆ including wire hammers 21 ₁ to 21 ₆ as a first group, and wire hammers 21 ₇ to 21 _{12 .} A second group includes wire hammer units 20 ₇ to 20 ₁₂ including
Drive mechanism 22 ₁ of the first wire hammer unit group
22 _{6 to} 22 6 and drive mechanisms 22 ₇ to 22 ₁₂ for the second wire hammer unit group are stacked on the carriage.

FIG. 5 is an explanatory diagram showing the main parts of an embodiment of the present invention, and the same parts as in FIG. 1 are given the same reference numerals. As is clear from FIG. 5, the drive mechanisms 22 ₁ to 22 ₆ of the first wire hammer unit group are arranged in the lower layer, and the drive mechanisms 22 ₇ to 22 ₁₂ of the second wire hammer unit group are arranged in the upper layer. ing. Note that these drive mechanisms are constructed using solenoid mechanisms. FIG. 6 is an arrangement example diagram of such a drive mechanism viewed from above, where a shows the drive mechanisms 22 ₁ to 22 ₆ of the first wire hammer unit group, and b shows the drive mechanisms 22 1 to 22 6 of the second wire hammer unit group. The drive mechanisms 22 ₇ to 22 ₁₂ are shown.

The operation of the device configured in this way will be explained.

For analog recording of normal measured values, six wire hammers 21 ₁ to 21 ₆ arranged along the carriage movement direction A are used. When recording a pattern as shown in FIG. 3, a total of seven wire hammers 21 are provided facing the color band _C4 of the ink ribbon 11 and perpendicular to the moving direction A of the carriage. ₄ , 21 ₇ to 21 ₁₂ are used.
On the other hand, when moving the ink ribbon 11, the dot position on the ink ribbon 11 at the previous stage is changed regardless of whether normal analog recording of measured values or pattern recording as shown in FIG. Move the carriage by the same amount in a direction diagonal to the direction of movement A of the carriage so as not to overlap.

According to such a configuration, the carriage is moved to the recording paper 3.
By moving once in the direction perpendicular to the feeding direction of 0, it is possible to record a pattern as shown in Figure 3, and the time required for recording is shorter than in the conventional example as shown in Figure 2. It can be shortened to 1/7. Also,
The amount of movement of the ink ribbon 11 can be minimized, the ink ribbon 11 can be used effectively, and the time required for moving the ink ribbon 11 can be shortened. In addition, the seven wire hammers 21 ₄ , 21 ₇ to 21 ₁₂ used for pattern recording are installed perpendicular to the carriage movement direction A, so calculation processing for pattern recording is easy. nothing.

In the above embodiment, the ink ribbon is 6
Although an example is shown in which recording is performed using six wire hammer units using different colors, the number of combinations of these color bands and the number of wire hammer units can be increased or decreased as appropriate.

Further, the specific color band position of the ink ribbon used for pattern recording is not limited to the embodiment, and may be changed depending on the purpose.

Further, the number of wire hammers in the wire hammer unit used for pattern recording is not limited to the embodiment, and can be increased or decreased as appropriate depending on the required printing quality.

Furthermore, if it is desired to clearly indicate which pattern recording results belong to a specific item, for example, each item may be associated with a specific color and underlined with that color.

Furthermore, the arrangement direction of the wire hammer of the wire hammer unit used for pattern recording and the moving direction of the ink ribbon are not limited to those shown in this example. For example, as shown in FIG. Wire hammer 2 of the wire hammer unit used for recording patterns by moving along the feeding direction of
1 ₇ to 21 ₁₂ may be oblique to the moving direction of the ink ribbon 11.

As described above, according to the present invention, it is possible to record the magnitude of a measured value in analog color dots, and also record the measured value, time, range, and other measurement conditions in a high-speed pattern in a specific color, which has practical effects. is big.
