In this way, the corresponding electrothermal converter 55 is driven (energized) based on the image signal or the ejection signal to cause the liquid passage 5 to flow.
A recording unit (recording head) 1 is configured to cause the ink in the film 4 to boil and to eject the ink from the ejection port 52 by the pressure generated at that time.

Therefore, the ink jet recording apparatus according to the present invention is configured such that a waiting time is provided at the time of line feed when recording with a high dot density, and the receiving of recording data from the host computer is interrupted during the waiting time. Has been done.

FIG. 1 is a block diagram showing a control system of an embodiment of the ink jet recording apparatus of the present invention, and FIG. 2 is a flow chart showing a control procedure of the recording apparatus of FIG.

In FIG. 1, the control unit 20 includes an MPU 21.

The control unit 20 controls the input / output port 25.
Data is input from the interface 27, the DIP switch 28, and various sensors 30 while being connected to the operation panel 26 via. When the port RA (25a) of the input / output port 25 is "L" (low), it means that the host computer (not shown) cannot receive the record data via the interface circuit 27. , And when "H" (high),
It is set to instruct the host computer via the interface circuit 27 that the print data can be received.

The control unit 20 also controls the carriage motor (CR motor) 5 via the drive circuit 31 and the drive circuit 32.
The transfer motor (LF motor) 7 is driven through the drive circuit 33.
The recording head 1 is controlled via the drive circuit 34, and the heater 29 is controlled via the drive circuit 34. Power is supplied from the power supply unit 35 to the control system shown in FIG.

The operation of the first embodiment of the ink jet recording apparatus according to the present invention will be described below with reference to FIGS. 1 and 2.

When the power is turned on in step S1, an initial operation required for recording, such as initial conveyance of the recording material, is performed in step 2. In step S3, it is determined whether or not the operation panel 26 is online (ON LINE). If the operation panel 26 is not online, that is, offline, the process proceeds to step S4 and the port RA
(25a) is set to "L" and the process returns to step S3. On the other hand, if the operation panel 26 is online in step S3, the port RA (25a) is turned on in step S5.
H. That is, the port RA is kept at "L" until the operation panel 26 is brought online, and the port RA is made "H" when it is brought online.

When the port 25a is "H", the recording data is sequentially received via the interface circuit 27,
It is stored in the reception buffer area of the RAM 23. Also, M
The PU 21 analyzes the reception data stored in the reception buffer area, develops it into dot matrix image data, and stores it in the image buffer area of the RAM 23.

In step S6, it is determined whether or not the image data for one line has been completed, that is, whether or not recording has started. When the image data for one line has been prepared, the process proceeds to step S7 to start recording. In step 8, it is determined whether or not the recording for one line is completed. When the recording is completed, in step S9, it is determined whether or not the dip switch 28 is on (ON). The dip switch 28 is a switch preset by the operator, and controls according to the present invention such as setting a waiting time at the time of line feed when recording with high dot density or not receiving recording data. Is set to ON by the operator when the operator desires to perform the above operation, and is set to OFF when such control is not desired.

If it is determined that the dip switch 28 is off, the process proceeds to step S13, the recording material is conveyed (paper feed), and then the process returns to step S3 described above. Then, the recording of the line is performed again.

On the other hand, in step S9, the DIP switch 2
If it is determined that 8 is set to ON in advance,
In step S10, the port RA (25a) is set to "L". Then, the process proceeds to step S11, and the timer 24 waits for a certain set time (for example, 3 seconds). By the standby of the paper feeding, the recording portion of the recording material stays on the platen 9 for a set time (3 seconds), is heated by the heater 29 provided on the back side of the platen 9, and the drying of the ink is promoted.

At the same time, the port RA (25
Since a) is "L", the interface circuit 27 does not receive the recording data. Then, after waiting, the process proceeds to step 12 to set the port RA (25a) to "H".
As a result, the reception of recording data is restarted. Next, in step S13, the recording material is conveyed (paper feed).

By providing a plurality of dip steps 28, the waiting time in step 11 can be appropriately selected.

In the above-described embodiment, no recording data is received during the waiting time at the time of line feed when recording with a high dot density, so if the waiting time is set long, it is connected to the recording device. A certain host computer causes a timeout error. In view of this, the second embodiment described below with reference to FIG. 3 is configured so that print data is not received for a certain period of time during a line feed when printing with high dot density. ..

FIG. 3 is a flow chart showing a second embodiment of the control procedure of the ink jet recording apparatus.

Steps S101 to S108 are the same as S1 to S8 of the first embodiment. When it is determined in step S108 that the recording for one line is completed, it is determined in step 109 whether the dip switch 28 is on. If the dip switch 28 is off, step S
After proceeding to 114 and carrying the recording material, step 1
Return to 03 to record the next line.

On the other hand, if it is determined in step 109 that the dip switch 28 has been set to ON in advance, the timer 24 waits for a certain set time in step S110. Next, in step S111, the port RA (25a)
To "L". Then, the process proceeds to step S112, and the timer 24 waits for a certain set time. And after waiting,
In step S113, the port RA (25a) is set to "
H ".

As a result, steps S110 to S113 are performed.
During the waiting time, the recording portion of the recording material stays on the platen 9 and is heated by the heater 29 provided on the back side of the platen 9 during this time to accelerate the drying of the ink. Since the port RA is "L" during the step 112 during the waiting time, the interface circuit 27 does not receive the recording data. Step S112
After that, the process proceeds to step S114, and the recording material is conveyed. By providing a plurality of dip switches 28, it is possible to configure so that the times of step S110 and step S112 are appropriately selected.

In the third embodiment, a plurality of periods for receiving the recording data and a plurality of periods for not receiving the recording data are alternately provided during the waiting time at the time of line feed when the recording with high dot density is performed. FIG. 4 is a block diagram showing a control system of the recording apparatus of the embodiment, and FIG. 5 is a flowchart showing a control procedure of the recording apparatus of FIG.

The control system of FIG. 4 uses one timer in the control system of FIG. 1, but has two different set times.
The difference is that one timer A (24a) and one timer B (24b) are used, and the other parts are the same, so detailed description will be omitted.

In FIG. 5, steps S201 to S20 are performed.
8 is the same as steps S1 to S8 of the first embodiment. When it is determined in step 208 that the recording for one line is completed, it is determined in step 209 whether the dip switch 28 is on. Here, the DIP switch 28
If is off, the process proceeds to step S216 to carry the recording material, then returns to step S203, and thereafter, the operations in and after step S203 are performed to record the next line.

On the other hand, if it is determined in step S209 that the dip switch 28 has been set to ON in advance,
In step S210, the timer A (24a) is started. That is, the timer A having a certain set value starts counting. Then, in step 211, the timer B (24
After counting the time set in b), the process proceeds to step S212 and the port RA (25a) is set to "L". That is, until the port RA becomes "L", the timer B
Wait for the time set in.

Next, in step S213, the timer B waits for the set time again, and after waiting, the process proceeds to step S214.
The port RA is set to "H". Then, in step S215, it is determined whether or not the count of the timer A has reached a certain set value, and if it has not yet reached the set value, step 211
Then, the operation of steps S211 to S215 is repeated.

When it is determined in step 215 that the count of the timer A has reached the set value, the process proceeds to step 216 and the recording material is conveyed.

As a result, the step S210 to S215 counted by the timer A becomes the waiting time at the time of line feed, and the recording portion of the recording material stays on the platen 9 during this time and is provided on the back of the platen 9 or the like. Heater 29
Is heated to accelerate the drying of the ink. Here, since the waiting time in steps 211 and S213 is shorter than the waiting time at the line feed counted by the timer A (24a), the port RA ( 25a) is "
Port RA that does not receive recorded data during the H "period
The periods in which (25a) is "L" are present alternately.

Further, by providing a plurality of dip switches 28, it is possible to appropriately select the standby time of the switches 211 and S213 and the set value for judging the end of the count of step S215.

In the fourth embodiment, when the remaining amount of the receiving buffer becomes less than or equal to a set value during the waiting time at the time of line feed when recording with high dot density, there is a period during which recording data is not received. It is configured as follows.

FIG. 6 is a flow chart showing the control procedure of the recording apparatus of the fourth embodiment. The block diagram of the control system of the recording apparatus of this embodiment is the same as that of FIG. 1, and one timer is used.

Steps S301 to S308 are the same as S1 to S8 of the first embodiment. When it is determined in step S308 that the recording for one line is completed, step 309
Then, it is determined whether or not the dip switch 28 is on.

If the dip switch 28 is off, the process proceeds to step S314 to carry the recording material, and then the process returns to step S303 to perform the operations in and after step S303 to record the next line. I do.

On the other hand, if it is determined in step S309 that the dip switch 28 has been set to ON in advance,
In step S310, it is determined whether or not the number A of unanalyzed valid data in the reception buffer of the RAM 23 (hereinafter referred to as the reception data remaining amount) exceeds the set value B.

If the received data remaining amount A does not exceed the set value B, the process proceeds to step S312, and the timer 24
Waits for a certain set time. Then, step S31
The port RA is set to "H" in step 3, and then step S31.
After the recording material is conveyed to step 4, step S303
Return to.

On the other hand, if the remaining amount A of received data exceeds the set value B in step S310, the flow advances to step S311 to set the port RA to "L". And step S3
At 12, the timer 24 waits for a certain set time. After waiting, the process proceeds to step S313 and the port RA is set to "H". Subsequently, the process proceeds to step S314 to carry the recording material, and then the process returns to step S303 to record the next line.

That is, until the remaining amount of received data exceeds a certain set value, the record data is normally received even during the waiting time at the line feed, but when the remaining amount of received data exceeds the set value, the receiving buffer Since the unused area in the area is small, the recording data is not received during the waiting time at the time of line feed.

Further, by providing a plurality of dip switches 28, the setting time in step S312 can be appropriately selected. Further, in the fourth embodiment, the record data is not received during the waiting time at the time of line feed, but as in the second embodiment or the third embodiment,
The recording data may not be received during a part of the waiting time at the time of line feed.

The present invention can be applied to an ink jet recording apparatus that uses a recording means (recording head) using an electromechanical transducer such as a piezo element, but among them, thermal energy is used. In this way, an excellent effect can be obtained in an ink jet recording apparatus of the type that ejects ink.

It is valid.

Due to the growth and contraction of the bubbles, the liquid (ink) is ejected through the ejection opening to form at least one droplet. It is more preferable to make this drive signal into a pulse shape, because the bubble growth and contraction are immediately and appropriately performed, so that the ejection of the liquid (ink) with excellent responsiveness can be achieved. As this pulse-shaped drive signal, US Pat.
Those described in US Pat. Nos. 4,633,359 and 4,345,262 are suitable. Incidentally, US Pat. No. 43131 of the invention relating to the rate of temperature rise of the heat acting surface.
If the conditions described in No. 24 are adopted, even more excellent recording can be performed.

In addition, even with the serial type as in the above example, it is possible to electrically connect to the device body or supply ink from the device body by mounting it on the recording head fixed to the device body or on the device body. The present invention is also effective when a replaceable chip type recording head or a cartridge type recording head in which an ink tank is integrally provided in the recording head itself is used.

Further, it is preferable to add recovery means for the recording head, preliminary auxiliary means, and the like, which are provided in the present invention as a configuration of the recording apparatus, because the effects of the present invention can be further stabilized. If these are specifically mentioned,
Capping means, cleaning means, pressurizing or suctioning means, electrothermal converter or other heating element or preheating means by a combination thereof, and ejection different from recording are applied to the recording head.
