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 is relatively compact and has a 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 the width direction, and 12 is an ink ribbon 11. 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 forming the wire hammer unit 20; A drive mechanism selectively drives the wire hammer 21 according to a recording signal, 30 is a recording paper, and 40 is a platen. The ink ribbon unit 10 and the wire hammer unit 20 are installed in the carriage so that the wire hammer 21 faces the recording paper 30 with the ink ribbon 11 in between.

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 "O" as shown in the figure, move the carriage seven times to zero on the recording paper 30. The ink ribbon 11 and the recording paper 30 must be moved seven times in a 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 uses a carriage that reciprocates in a direction perpendicular to the feeding direction of the recording paper that is wound around a cylindrical platen and is fed in multiple colors in the width direction. a first wire hammer unit group including a plurality of wire hammer units arranged along the carriage movement direction so as to correspond to each color band of the ink ribbon, and a specific color of the ink ribbon. A second wire hammer unit group consisting of a plurality of wire hammer units arranged in a direction perpendicular to the moving direction of the carriage so as to correspond to the band, each wire hammer is connected to the axis of the platen through the ink ribbon and the recording paper. They are characterized in that they are arranged in a stacked manner with spacers interposed therebetween so as to face each other radially.

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 through the spacer 50. It is placed on the upper layer. Here, when focusing on each wire hammer 21 ₁ to 21 ₁₂ ,
These wire hammers 21 ₁ to 21 ₁₂ are radially opposed to the axis of the platen 40 via the ink ribbon 11 and the recording paper 30 without intervening a guide member that forcibly bends the wire. . Therefore, it is possible to use a wire with a relatively large diameter (for example, 0.5 mm) and short length, and to miniaturize the wire hammer unit, which is suitable for recording the size of the measured value in analog color dots. can be achieved. Note that these drive mechanisms are constructed as a free flight type using a solenoid mechanism. Figure 6 is an example of the layout of such a drive mechanism viewed from above, and (a) is the first
Drive mechanism 22 ₁ to 2 of the wire hammer unit group
₂₆ , and (b) shows the drive mechanisms ₂₂₁ to ₂₂₁₂ of the second wire hammer unit group.

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 ₄ are provided facing the color band C ₄ of the ink ribbon 11 and perpendicular to the moving direction A of the carriage. 21 ₇ to 21 ₁₂ are used.
On the other hand, when moving the ink ribbon 11, regardless of the normal analog recording of measured values or the recording of a pattern as shown in FIG. The carriage is moved by the same amount in a direction oblique to the direction of movement A of the carriage.

According to such a configuration, the carriage is moved to the recording paper 3.
By moving once in the direction perpendicular to the feed direction of 0, it is possible to record the pattern shown in Figure 3, and the time required for recording is 1/1 compared to the conventional example shown in Figure 2. It can be shortened to 7. Also,
The amount of movement of the ink ribbon 11 may be the minimum amount, the ink ribbon 11 can be used effectively, and the time required for moving the ink ribbon 11 can be shortened. Furthermore, since the seven wire hammers 21 ₄ , 21 ₇ to 21 ₁₂ used for pattern recording are provided perpendicular to the carriage movement direction A, the arithmetic processing for pattern recording is also simple. Furthermore, since the wires of each wire hammer 21 ₁ to 21 ₁₂ can be radially opposed to the axis of the platen 40 without intervening a guide member that forcibly bends the wires in the middle, the wire hammer unit can be made smaller. can be achieved.

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.

Furthermore, 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.

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

As described above, the present invention has a relatively small and simple configuration, and it is possible to record the magnitude of measured values in analog color dots, and to record measured values, time, range, and other measurement conditions in specific colors in high-speed patterns. A wire dot color recorder can be realized, which has great practical effects.
