Abstract

PURPOSE:To prevent the occurrence of print blurring by properly repeating the recording by controlling the recorder in such a way as to make multiple writing at the beginning of the next recording when the time during which no recording action is made is longer than a given time period. CONSTITUTION:DW flat to represent double-writing designation is set, and a minimum value for the time during which the pen tip is dried and letter blurring occurs is set as a drying time Td. No-print time TnP is set to zero (0) for judging that no printing action is made by a printer 7. DWNUM is set to one (1) for designating the number of double-writing letters DWNUM to one letter, and the number letters PNUM printed by the printer 7 is set to zero (0). A power-on initializing process is thus ended. A timer interruption procesing necessary for processing other than double writing is made. The total sum of TnP and timer interruption interval is used as new TnP. TnP is compared with Td in terms of size, and when TnP is larger, DW flag is set.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a recording device, and more particularly to a recording device such as a plotter printer or an inkjet printer that can record on recording paper.

[Conventional technology]

In recent years, electronic devices such as plotter printers and inkjet printers that can record on recording paper have been developed. However, when printing using this type of printer, there is a drawback that some of the printed characters are blurred and difficult to read.

An example of a pen used in a conventional plotter printer is shown in FIG. 2, and blurred printing will be described using this pen as an example.

In FIG. 2, the amount of ink stored in the batting 13 is 1
Due to capillary force, it passes through the relay core [2] and further passes through the capillary tube 11 to reach the pole IO.

When the pole 10 rotates in contact with the paper, the ink adhering to the surface of the pole 10 is transferred to the paper.

Here, the air 14 is provided in order to maintain the same pressure between the outside and the inside and not to obstruct the ejection of ink.

However, since the composition of the ink is mostly water, it is vulnerable to dry explosion, and if the tip of the Rn is left open, it is unavoidable that the ink will dry out.

When the pen tip dries and cleans, the initial start of writing becomes poor and this causes blurred printing.

Furthermore, this type of plotter printer is often used in a watery state, and the only thing that affects the movement of the ink is capillary force, and it is not easily affected by gravity, so it is difficult to move the ink during printing. Occasionally, printing may become blurred.

As mentioned in Section 4 above, plotter printers have a drawback in that they tend to blur when drawing with a pen.

The above-mentioned conventional example has been described using a plotter printer as an example, but inkjet printers and the like also have a nozzle for ejecting ink, so it is difficult to avoid the drawback of blurred printing due to problems in the principle of such a structure.

[Problem that the invention seeks to solve]

Therefore, it is an object of the present invention to provide a recording apparatus that prevents blurred printing by appropriately repeating recording when recording using ink as described above.

Another objective of the unreleased 1gI is to provide a recording device that prevents blurring of recording by performing multiple recording at the start of the next recording when no recording operation is performed for a predetermined period of time. .

[Failure to solve the problem]

In order to achieve the objective (1), the present invention provides a recording apparatus having a recording means for recording on recording paper, a setting means for setting a predetermined time, and a predetermined time set by the setting means. Based on the comparison result of the comparison means for comparing with the time when no recording operation is performed, and the comparison means listed in L,
The present invention is characterized by comprising a control means for controlling the recording means to perform multiple writing when the next recording starts when the time during which no recording operation is performed is longer than the predetermined time.

[For production]

According to the present invention, if a specified key for double recording is pressed while a character is being output by a printer, that key will be pressed twice from the beginning of the sentence currently being recorded only while the printer is connected. Since double recording is performed, it is possible to flexibly deal with blurred characters that tend to occur immediately after printing starts by recording an arbitrary number of characters on two nails.

In step S45, the address of the memory containing the print data is returned to the value at the time the DWB key was pressed, and the process ends.

〔Effect of the invention〕

As explained above, according to the present invention, if a printing operation is not performed for a predetermined period of time, an arbitrary number of characters can be double recorded to prevent blurring of characters, which is likely to occur after the next printing starts. Able to deal with emergencies.

Although the above example describes the case where characters are recorded, the present invention is not limited to this case, and in addition to character units, recording can also be performed in predetermined recording units such as the first position of a predetermined figure. It goes without saying that this method can be effectively applied when double recording is performed.

Furthermore, in the above example, the input element '
Although the case of a DW single key, DWF key, and DWB key is illustrated as an example, the input means is not constituted only by these keys, for example, the display device δ5 in FIG.
At the top, by displaying the designation in double writing, moving the cursor to that position, and pressing the execution key on the keypad device 6, such double writing instruction input can be generated. In general, the form of the force does not matter.

Furthermore, in the above example, the case where recording is performed twice has been explained, but this recording may be performed three times.

The present invention includes the case where multiple recording is performed so that recording is not blurred. Further, when double or triple overwriting is performed, the printing pressure or the amount of ink ejection may be reduced to prevent blurring and the like.
