Description

[Detailed Description of the Invention] This invention relates to a recording device that performs recording in multiple colors using a single recording pen.

2. Description of the Related Art When recording in multiple colors, a recording device has conventionally been proposed in which recording pens having different recording colors are prepared and the recording pens are switched depending on the recording color.

However, such a recorder has the disadvantage that the recording pen switching mechanism is complicated and large.

This invention provides a recorder capable of recording in multiple colors using a single recording pen without using a complicated switching mechanism as described above.

Hereinafter, the present device will be explained based on the embodiment shown in the drawings.

However, in the figures, the same numbers refer to the same things.

In Fig. 1, reference numeral 1 denotes a pen tip made of a conductive material, and a conductive minute metal ball 2 (hereinafter referred to as a ball) is incorporated into the tip for the purpose of smoothing writing and the flow of electric fluid. ).

The pen tip 1 and the ball 2 are in contact with each other.

A conductive foil 3, which is partially overlapped with the pen tip 1, is closely attached to the outer periphery of the pen.

Figure 2 shows the components of the recording device, where 4 is a pen fixture made of a conductive material provided at the bottom of the sliding arm of the guide rail 5 and has a cylindrical shape, and 6 is inserted into the cylinder of the pen fixture 4. It is a conductive screw that tightens the pen.

Since the screw 6 and the pen fixture 4 contact the conductive foil 3, the screw 6 and the ball 2 are electrically short-circuited.

Reference numeral 7 denotes a voltage application section that applies a voltage to the screw 6, and 8 is a control section that sends out a control signal for controlling the voltage application section 7.

Reference numeral 9 is an energized recording paper that changes color only in the energized portion, and is transported at a constant speed over the electrode plate 10 in the direction of the arrow.

With the above configuration, when the voltage application section 7 is not sending out an applied voltage by the control section 8, the recording line on the recording paper 9 is the color of the electrolyte of the pen.

This corresponds to period A in FIG.

Next, when the voltage application section 7 is operated by the control section 8, during this period (period B in FIG. 3), the recording paper on the recording paper 9 is affected by the color of the pen color liquid and the energization from the ball 2. The color is mixed with the color peculiar to recording paper, which changes color.

That is, one continuous recording line can be expressed using two colors.

Of course, it goes without saying that in order to obtain the above two colors (the color of the pen color liquid and the mixed color), the color of the pen liquid must not be black.

This is because even if black and the color caused by discoloration are mixed, the result is still black, and this makes it impossible to achieve multicolor recording, which is the object of the present invention.

Thus, according to the embodiment of the present invention, by making relatively simple improvements to the pen, it is possible to record in multiple colors using a single recording pen.

Therefore, the time required from the start of driving of the recording device to the time when the recording device becomes in a measurable state, that is, the transition period, can be identified on a single recording line.

Furthermore, if the control unit 8 is set to perform multicolor recording only during the period in which characteristics specific to the object to be observed appear, it is possible to prevent the above characteristics from being overlooked. It is possible to provide discriminative information without the risk of misidentification even in situations.

Furthermore, it is possible to record not only single information but also multiple pieces of information.
