Hereinafter, a recording apparatus according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
Initially, the outline | summary of the recording device 1 of a present Example is demonstrated.
FIG. 1 is a schematic side view of a recording apparatus 1 according to the present embodiment.

  As shown in FIG. 1, the recording apparatus 1 of this embodiment includes a feeding unit 2 that can feed out a roll R <b> 1 of a recording medium P for recording. Further, a transport mechanism 3 is provided as a transport unit that transports the recording medium P in the transport direction A by the adhesive belt 10 that supports the recording medium P on the support surface F to which the adhesive is attached. In addition, a recording mechanism 4 is provided that records the recording head 7 by reciprocating scanning in a reciprocating movement direction B that intersects the conveyance direction A of the recording medium P. Further, a cleaning mechanism 15 for the adhesive belt 10 is provided. Furthermore, a winding mechanism 18 having a winding shaft 17 for winding the recording medium P and a cutter 16 for cutting the recording medium P being wound is provided.

  The feeding unit 2 includes a rotating shaft 5 that also serves as a setting position of the roll R1 of the recording medium P for recording, and conveys the recording medium P from the roll R1 set on the rotating shaft 5 via the driven roller 6. The structure can be extended to the mechanism 3. When the recording medium P is fed out to the transport mechanism 3, the rotating shaft 5 rotates in the rotation direction C.

The carriage motor 30 (see FIG. 2) is reciprocally moved. In FIG. 1, the reciprocating direction B is a direction perpendicular to the paper surface.
During recording, recording is performed by reciprocating the recording head 7, but the conveyance mechanism 3 stops conveyance of the recording medium P during recording scanning (while the recording head 7 is moving). In other words, during recording, the reciprocating scanning of the recording head 7 and the conveyance of the recording medium P are alternately performed. That is, at the time of recording, the conveyance mechanism 3 intermittently conveys the recording medium P (the adhesive belt 10 is moved intermittently) corresponding to the reciprocating scanning of the recording head 7.

  The cleaning mechanism 15 of the adhesive belt 10 includes a cleaning brush 13 configured by connecting a plurality of cleaning rollers in the rotation axis direction, and a tray 14 containing a cleaning agent for cleaning the cleaning brush 13.

A winding paper tube or the like is set on the winding shaft 17. By winding the recording medium P around this, the recording medium P can be wound as a roll R2.

  The recording apparatus 1 of the present embodiment is a recording apparatus that transports a roll-shaped recording medium P supported by the adhesive belt 10, but is not limited to the recording apparatus having such a configuration. For example, in addition to the roll-shaped recording medium P, a single-sheet recording medium P may be sandwiched and transported by a pair of rollers as a transport unit.

Next, the electrical configuration of the recording apparatus 1 of the present embodiment will be described.
FIG. 2 is a block diagram of the recording apparatus 1 of the present embodiment.
The control unit 23 is provided with a CPU 24 that controls the entire recording apparatus 1. The CPU 24 is connected via a system bus 25 to a ROM 26 that stores various control programs executed by the CPU 24 and a RAM 27 that can temporarily store data.

Further, the CPU 24 is connected to a head driving unit 28 for driving the recording head 7 via the system bus 25.
The CPU 24 is connected to a motor drive unit 29 for driving the carriage motor 30, the transport motor 31, the feeding motor 32, and the take-up motor 33 via the system bus 25.
Here, the carriage motor 30 is a motor for moving the carriage on which the recording head 7 is mounted. The transport motor 31 is a motor for driving the transport roller 8. The feeding motor 32 is a rotating mechanism of the rotating shaft 5, and is a motor that drives the rotating shaft 5 in order to send the recording medium P to the transport mechanism 3. The winding motor 33 is a drive motor for rotating the winding shaft 17.

The CPU 24 is connected via a system bus 25 to a cutter driving unit 19 that drives the cutter 16 so as to cut the recording medium P.
Further, the CPU 24 is connected to the input / output unit 20 via the system bus 25, and the input / output unit 20 is connected to a PC 21 for transmitting and receiving data such as image data and signals.

With this configuration, the control unit 23 according to the present embodiment can perform drive control (recording control) of the recording apparatus 1.
Next, a recording operation that can be executed by the recording apparatus 1 of the present embodiment under the control of the control unit 23 will be described.
Here, FIG. 3 is a diagram showing a drive waveform of a voltage applied to the recording head 7 of the recording apparatus 1 of the present embodiment.

FIG. 4 is a schematic diagram showing the ink dots I landed on the recording medium P recorded by the recording operation of ejecting one dot based on the pixel data for one pixel, and the ink dots I are likely to spread. FIG. 6 is a schematic diagram when a recording medium P is used.

FIG. 5 is a schematic diagram showing the ink dot I landed on the recording medium P, which is recorded by the recording operation of ejecting one dot based on the pixel data for one pixel, and the ink dot I is difficult to spread. FIG. 6 is a schematic diagram when a recording medium P is used.

FIG. 6 is a schematic diagram showing ink dots I landed on the recording medium P, recorded by a recording operation in which a plurality of dots are ejected in one pass based on pixel data for one pixel. FIG. 6 is a schematic diagram when a recording medium P that is difficult to spread is used.
6A is a plan view showing the ink dots I landed on the recording medium P, and FIG. 6B is a front view showing the ink dots I landed on the recording medium P.

FIG. 7 is a schematic diagram showing ink dots I landed on the recording medium P, recorded by a recording operation in which a plurality of dots are ejected in a plurality of passes based on pixel data for one pixel. FIG. 6 is a schematic diagram when a recording medium P that is difficult to spread is used.
7A is a plan view showing the ink dots I landed on the recording medium P, and FIG. 7B is a front view showing the ink dots I landed on the recording medium P.

  The numbers of ink dots I in FIGS. 4 to 7 correspond to the address numbers of pixel data for one pixel in the image data sent from the PC 21. Therefore, in FIG. 4 and FIG. 5, one ink dot I corresponding to one address number corresponding to pixel data for one pixel is formed from 1 to 8. 6 and 7, a plurality (9) of ink dots I corresponding to one address number corresponding to pixel data for one pixel are formed from 1 to 8.

  In the case of image data sent from the PC 21, when recording is performed by a recording operation in which one dot is ejected based on pixel data for one pixel of the image data, as shown in FIGS. 4 and 5, The landing diameter of the ink dots I that have landed on the medium P varies greatly depending on the type of recording medium. For example, when the recording medium P such as paper is used, the landing diameter of the ink dot I tends to increase as shown in FIG. 4, and when the recording medium P such as cloth is used, the ink dot I tends to increase. The landing diameter of the dot I tends to be small as shown in FIG. For this reason, conventionally, in order to suppress the level of image density associated with the type of recording medium P to be used, the driver software attached to the recording apparatus 1 in the PC 21 according to the type of recording medium P to be used. Was used to convert image data.

For example, when forming a high-density image using the recording medium P in which the ink dots I are difficult to spread, pixel data that is not originally recorded in the image data before conversion is changed to pixel data that is recorded in the image data after conversion. I was doing the work of converting. More specifically, such a conversion operation is performed on the pixel data around the pixel data to be recorded in the image data before conversion.
However, when the image data is large or when the performance of the PC 21 to be used is low, it takes time to convert such image data.
4 and 5 are the second nozzle N from the top and the second nozzle N from the bottom among the six nozzles N of the recording head 7 shown in FIGS. 4A and 5A. The state recorded using the nozzle N is shown.

Therefore, the recording apparatus 1 of the present embodiment forms an image as shown in FIG. 4 using the recording medium P in which the ink dots I are difficult to spread without performing such image data conversion. to enable. That is, it is possible to record at a plurality of densities based on one image data.
The recording apparatus 1 according to the present embodiment includes a recording head 7 that can eject ink from nozzles N based on image data. The recording medium P has a plurality of densities based on pixel data for one pixel in the image data. The ink can be discharged. That is, the image data is input without converting the image data by the PC 21 or the like, and the density of the image formed on the recording medium P corresponding to the type of the recording medium P based on the input image data. It is a configuration that can be adjusted. For this reason, it is possible to record at a plurality of densities based on one image data.

Hereinafter, how the recording apparatus 1 of the present embodiment performs recording at a plurality of densities based on one image data will be described.
As described above, the recording apparatus 1 of the present embodiment has a configuration capable of performing recording by reciprocating the recording head 7 in the reciprocating movement direction B with respect to the recording medium P.
More specifically, a carriage motor 30 is provided as a moving unit capable of reciprocating the recording head 7 in the reciprocating direction B via the carriage. Here, the recording head 7 is provided with a nozzle row in which a plurality of nozzles N for ejecting ink are arranged along the transport direction A. That is, the carriage motor 30 is applied to the recording medium P in a direction (corresponding to the reciprocating movement direction B) intersecting the nozzle row direction (corresponding to the transport direction A), which is the direction in which the nozzles N in the recording head 7 are arranged. In this configuration, the recording head 7 is moved.

Then, as shown in FIG. 6, the recording apparatus 1 of the present embodiment is accompanied by one movement in the reciprocating movement direction B of the recording head 7 (for example, one movement in the direction B1). Based on pixel data for one pixel, ink can be ejected from one nozzle N a plurality of times (three times in FIG. 6).
In addition, as shown in FIG. 6A, among the six nozzles N of the recording head 7, not only the second nozzle N from the top and the second nozzle N from the bottom, but also the remaining nozzles N From the nozzle N, ink can be ejected from the nozzle N a plurality of times based on pixel data for one pixel.

Further, as shown in FIG. 7, the recording apparatus 1 according to the present embodiment moves a number of times in the reciprocating movement direction B of the recording head 7 (for example, movement in the direction B1, movement in the direction B2, With a total of three movements in the direction B1, the ink can be ejected a plurality of times from one nozzle N based on the pixel data for one pixel. FIG. 7 shows the vertical row a, row b, and row c in FIG. 7A among the ink dots I, row a by movement in the direction B1, row b by movement in the direction B2, and thereafter. Represents a state in which the column c is recorded by the movement in the direction B1. However, the column a and the column c can be recorded by moving in the direction B1, and the column b can be recorded by moving in the subsequent direction B2.
In addition, as shown in FIG. 7A, among the six nozzles N of the recording head 7, not only the second nozzle N from the top and the second nozzle N from the bottom, but also the remaining nozzles N From the nozzle N, ink can be ejected from the nozzle N a plurality of times based on pixel data for one pixel.

As shown in FIG. 6, ink is ejected a plurality of times from one nozzle N based on pixel data for one pixel as the recording head 7 moves once in the reciprocating direction B. In this case, if the ejection frequency at each nozzle N (frequency at which ink is ejected from the nozzle N) is too high, ejection failure may occur. In general, in order to eject an appropriate ink from the nozzle N, an appropriate waveform as shown in FIG. 3 is applied to the recording element of each nozzle N depending on the type of ink and the nozzle diameter. It is necessary to apply a voltage so that For this reason, it is necessary to set the ejection frequency so as to maintain an appropriate waveform, that is, to maintain an appropriate length of wavelength.
Accordingly, in the recording apparatus 1 of the present embodiment, the carriage motor 30 controls the controller 23 to control the carriage motor 30 to generate a plurality of inks from one nozzle N in one movement of the recording head 7 based on pixel data for one pixel. When the ink is ejected once (see FIG. 6), the recording head 7 is moved so that the moving speed of the recording head 7 in the reciprocating direction B is slower than when the ink is ejected once (see FIG. 5).
Specifically, as shown in FIG. 5B, when the moving speed of the recording head 7 when the ink is ejected once from one nozzle N as shown in FIG. In addition, the moving speed of the recording head 7 when the ink is ejected a plurality of times from one nozzle N is v / 3. In this way, even when ink is ejected a plurality of times based on pixel data for one pixel using the same nozzle N in one pass, adjustment is made so that the moving speed of the recording head 7 is reduced and the ejection frequency does not increase. The occurrence of defective discharge is suppressed.

  Further, as shown in FIG. 7, in the recording apparatus 1 of the present embodiment, the carriage motor 30 controls a plurality of inks from one nozzle N based on pixel data for one pixel under the control of the control unit 23. When ejecting twice, the recording head 7 can be moved several times. That is, the recording apparatus 1 of the present embodiment can perform so-called multi-pass recording when ink is ejected a plurality of times from one nozzle N based on pixel data for one pixel. For this reason, in the case where ink is ejected a plurality of times based on pixel data for one pixel using the same nozzle N, the ejection frequency is increased without reducing the moving speed of the recording head 7 by recording in multiple passes. It can adjust so that it may not become and can suppress that a discharge defect arises.

  Also, as shown in FIGS. 6 and 7, the printing apparatus 1 of the present embodiment, when ejecting ink from the printing head 7 a plurality of times based on pixel data for one pixel, causes ink from a plurality of nozzles N. It is comprised so that discharge is possible. Specifically, the nozzles used in FIG. 5 are only the second nozzle N from the top and the second nozzle N from the bottom among the six nozzles N of the recording head 7, whereas FIG. No. 7 used nozzles include not only the second nozzle N from the top and the second nozzle N from the bottom, but also the remaining nozzles N. More specifically, recording is performed based on the pixel data at addresses 1, 2, 3, and 4 with the third nozzle N from the top of the six nozzles N of the recording head 7, and the six nozzles N of the recording head 7 are recorded. Printing based on the pixel data at addresses 5, 6, 7 and 8 is performed by the third nozzle N from the bottom of the nozzles N. Since such a recording operation can be executed, it is possible to perform recording at a plurality of densities using a plurality of nozzles N based on pixel data for one pixel.

As shown in FIGS. 6 and 7, in the recording apparatus 1 of this embodiment, when ink is ejected from the recording head 7 a plurality of times based on pixel data for one pixel, the ink in the recording medium P Ink is ejected such that the landing positions of the inks are shifted from each other.
In the case where ink is ejected from the recording head 7 a plurality of times based on pixel data for one pixel, the case where the ink landing positions are different from each other than when the ink landing positions are the same position is recorded. The density of the image formed on the medium P can be increased efficiently. For this reason, the recording apparatus 1 of the present embodiment can efficiently record at a plurality of densities based on one image data. However, the present invention is not limited to this configuration, and when ink is ejected from the recording head 7 a plurality of times based on pixel data for one pixel, the ink is ejected so that the landing positions of the ink on the recording medium P do not deviate from each other. It may be configured to be.

  The recording apparatus 1 according to the present embodiment is 9 times as much as the recording control represented in FIGS. 6 and 7 based on one image data (reciprocating direction). The recording density was 3 times in B and 3 times in transport direction A). However, in addition to such recording control, it is possible to record at a density other than 9 times based on one image data, and at a density of multiple times in only one of the reciprocating movement direction B or the conveyance direction A. You can also
