Abstract

PURPOSE:To provide a recording apparatus not lowered in the detection function of an ink end mark and capable of confirming image data by performing image processing so as to be capable of discriminating the image data when the ink end mark recorded at a constant position is overlapped with the image data. CONSTITUTION:An ink injection part 11 injects ink while it is moved within a predetermined printing range to record image data and a predetermined mark 34 on recording paper 33. The mark 3 recorded on the recording paper 33 by the ink injection part 11 is detected by an ink end sensor 12 being a mark detector. When the mark 34 is not detected by the ink end sensor 12, an FCU 13 being an ink end detector detects the exhaustion of ink. When the mark 34 and the recording position of the image data cross each other, an image processing part 14 performs image processing, for example, reversal or bordering so as to be capable of discriminating the mark 34 and image data of the crossed part.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording apparatus in which image information is recorded and printed by an ink jet method, and more particularly to a technique for detecting ink shortage (ink end) and a technique for cleaning an ink ejecting portion in the recording apparatus.

[0002]

2. Description of the Related Art Conventionally, an ink jet type recording apparatus has been widely used in, for example, a plotter, a printer, a printing machine, an electronic blackboard, or the like. This recording apparatus fills a replaceable cartridge with ink, and the ink is ejected from the cartridge. Ink was supplied to the ejection portion to record and print image information on recording paper. In such a recording device, there are few that perform control such as detecting ink shortage and automatically interrupting the printing operation. In many cases, the user is left to run out of ink, and when the user recognizes that printing will not be performed due to running out of ink, the actual situation was to replace the ink cartridge.

Therefore, various mechanisms for detecting ink shortage have been proposed, one of which is, for example, a method using an ink cartridge, and an ink end sensor (for example, a light projecting type) provided in the ink cartridge itself is known. There is. A conventional recording device of this type is, for example, Japanese Patent Laid-Open No.
8-001563, 58-181674,
Alternatively, there are those described in JP-A-60-18350.

On the other hand, as another ink end detection mechanism, there is known a method of detecting an ink end by recording a predetermined mark on a recording sheet and detecting whether or not the mark is normally recorded. ing. With the ink end detection mechanism of the cartridge, if the recording operation is not performed for a long time, the ink may stick to the inner wall of the cartridge. In such a state, the sensor light does not pass through, Despite running out of ink
There is a risk of malfunction due to the presence of ink. However, according to the ink end detection mechanism of the mark recording method, since the ink end is detected through the actual recording operation, compared with the configuration in which the ink end is detected for the cartridge,
It is possible to detect the ink end in a form that matches the actual operation.

[0005]

However, in the conventional recording apparatus which employs such an ink end detection mechanism of the mark recording system, the image is formed within the movable range of the ink ejecting section, that is, the printable area. Since the information and the mark are recorded, important image information cannot be confirmed when the mark printing position and the image information printing position overlap at the same position.

As a countermeasure against this, it is conceivable to move the print position of the ink end mark to a position where there is no image information. However, if the print position of the ink end mark is changed, the mark detection function will be deteriorated and the effectiveness will be improved. Disappears. Therefore, in the invention according to claim 1, the image processing is performed so that the image information can be discriminated when the ink end mark recorded at a fixed position and the image information overlap each other, without deteriorating the detection function of the ink end mark. Moreover, it is an object of the present invention to provide a recording device capable of confirming image information.

It is another object of the present invention to provide a recording apparatus which makes it easier to view image information by changing the magnification of the image processing portion. Next, as a concern of the inkjet method, the nozzle portion of the ink ejection portion may be dried and cause ink clogging, which may adversely affect the ink ejection operation (recording operation). In this case, as a cleaning operation of the ink ejecting portion, a method of removing the dried portion of the ink by ejecting the ink or a method of sucking the ink ejecting portion from the outside can be considered. However, depending on the dryness of the ink, one cleaning operation is required. It may not be possible to remove dry parts.

Therefore, according to the third aspect of the present invention, when the ink end mark cannot be detected, the cleaning operation is performed once, and the cleaning operation is repeated a predetermined number of times in association with the continuous mark non-detection. It is an object of the present invention to provide a recording apparatus that can reliably remove ink and improve reliability. Further, in the invention according to claim 4, the recording paper for which no mark is detected is reversely conveyed to the original position when the cleaning is executed, so that the same recording paper is used again after the cleaning of the ink ejecting portion. An object of the present invention is to provide a recording apparatus that can reduce the consumption of recording paper as much as possible and can reduce the cost of consumables at low cost.

Next, although the ink drying of the ink ejecting portion has a bad influence on the printing of the image information and the ink end mark, the possibility of the ink ejecting portion being dried is small when the image information is continuously printed. On the other hand, when the time interval for printing the image information exceeds a certain time, the possibility of drying the ink ejecting section increases. For this reason,
It can be easily considered that an effective measure is to measure the elapsed time with a timer and to carry out the cleaning when a certain time or more has elapsed. However, if the cleaning of the ink ejection portion is performed only by the temporal control by the timer, the ink consumption amount is consumed regardless of the number of printed image information.

In view of this, in the invention described in claim 5, when printing is performed after a lapse of a certain time or more, cleaning is performed immediately before the printing, thereby preventing unnecessary wasteful cleaning irregularity and ink consumed by the cleaning. It is an object of the present invention to provide a recording device capable of reducing the amount and the charge.

The network control unit 21 executes facsimile transmission according to a predetermined transmission control procedure, and is connected to a transmission line network (for example, public telephone line network) that transmits and receives image information. The data memory 22 stores a work area and image information necessary for the operation of the FCU 13, and also stores data such as the shape of the mark 34 and the print position in this embodiment.

Next, the operation will be described. In FIG. 1B, the recording paper 33 is carried in from the left side in the figure, an image is printed by the ink ejecting section 11, passes above the conveying roller, and is discharged to the right side in the figure. The ink end sensor 12 is provided at a position closer to the discharge side than the ink ejection unit 11, is arranged above the recording paper 33, and at a position not in contact with the surface of the recording paper 33, and detects the ink end mark 34. The ink end sensor 12 is provided on the condition that it is provided above the recording paper conveyance path. For example, when the conveyance path is a path that draws a curve downward in accordance with the weight of the recording paper 33, The ink end mark 34 is provided at a position where it does not contact the recording paper 33 in accordance with this curved conveyance path, and the ink end mark 34 can be detected. In any case, the ink ejection unit 11
It does not matter as long as it can detect the ink end mark 34 printed by.

The moving range of the ink ejecting section 11 is limited by the guide rail 31, and the cleaning section 12 for cleaning the ink ejecting section 11 is the ink ejecting section 11.
It is provided within the movable range of. When performing cleaning, the ink ejecting unit 11 is replaced with the cleaning unit 12.
To the opposite position. The ink end mark 34 is printed at a preset position in the recordable printable range 41 shown in FIG. 2A, and the image data is also recorded in the recordable printable range 41. Here, as shown in FIG. 2B, the ink end mark 34 and image information such as “A” are displayed.
When trying to print at the same position, the image processing unit 14
As shown in FIG. 3, the intersecting portion is subjected to image processing to ensure the visibility of the image information “A”. That is, the image information “A” is reversed in the ink end mark 34 as shown in FIG. 3A, or the image information “A” in the ink end mark 34 is framed as shown in FIG. 3B. To do.

As described above, according to the first aspect of the invention, even when the ink end mark 34 and the image information are located at the same position and overlap each other, the image is reversed or bordered, so that the image can be recognized and the image can be recognized. Information can be reliably obtained, and the detection function of the ink end mark 34 is not deteriorated. Furthermore, the image processing unit 14 can perform a scaling process in accordance with the above image processing, and an example thereof is shown in FIGS. First, as shown in FIG.
3B is an enlargement or reduction of the inversion processing portion shown in FIG. In addition, FIG.
3B is a diagram in which the edging portion shown in FIG. 3B is emphasized by enlarging or reducing.

FIG. 5A shows an example of processing in which when the ink end mark 34 and the image "A" overlap, the dots of the image information inside the border are thinned out from the original image. Figure 5 (b)
Is a processing example in which when the ink end mark 34 and the image “A” overlap, the edging range is slightly enlarged, and the number of image information dots inside the edging is made larger than in the original image.

As described above, according to the second aspect of the invention, the image information overlapping the ink end mark 34 is changed because the image information overlapping the ink end mark 34 is changed based on the image processing such as inversion or edging. Can be made easier to see, and the effect of improving the reliability of the device is further enhanced. The image processing and the scaling processing are performed by the ink end mark 3
Execution processing is performed within a range that does not interfere with the detection function of No. 4.

If the ink runs out and printing cannot be performed, the ink end mark 34 cannot be printed, and the ink end sensor 12 cannot detect the ink end mark 34. When the ink end mark 34 cannot be detected, the ink ejecting unit 11 is cleaned by the cleaning unit 15. At this time, the conveyance roller 35 reverses by a certain amount, and the recording paper 33 is ejected onto the ink ejection unit 1.
Pull back to side 1. The amount of pulling back is set to a position where the transport roller 35 can transport the recording paper 33 in the forward direction again after pulling back, and if possible, it is returned to the front of the ink ejecting unit 11.

The cleaning performed by the cleaning unit 12 is performed by removing the dried ink from the ink ejecting unit 11.
It is for removing clogging of ink nozzles, and is a method of using an ink ejection method, a method of sucking ink from an ejection portion from the outside, or both of them. After the cleaning is completed, the operation of printing the image information is started again, and the ink end mark 34 is detected. Ink end mark 34 continuously
If it is not detected, the cleaning is performed again, and the recording paper 33 is also pulled back to the previous position by the transport roller 35.

Here, the number N of continuous cleaning operations can be set in advance, and when the number of times n is exceeded, it is determined that the ink in the ink cartridge 32 has run out, and the ink end notification unit 16 makes a sound (buzzer). , Bell, telephone, etc.) or light (bulb, LED, liquid crystal, etc.) to notify the user and prompt replacement of the ink cartridge. As described above, in the embodiment of the third aspect, the cleaning operation is repeatedly performed when the ink end mark 34 cannot be continuously detected, so that the dry ink in the ink ejecting portion 11 can be reliably removed. The reliability of the device can be improved.

In the embodiment of claim 4,
At the time of cleaning, the recording paper 33 is pulled back to a predetermined standby position, and is made to stand by in preparation for a print command after the cleaning is completed. When the print command arrives, the recording paper 33 is conveyed to the ink ejecting unit 11 again and is printed. Therefore, the cost of the recording paper 33 as a consumable item can be kept low.

By the way, when the recording apparatus is used as a plotter for a facsimile machine or the like, the facsimile machine continuously turns on the power source, and therefore irregular printing is forced over time. Therefore, when a certain time or more, for example, t time or more has elapsed from the previous printing, the ink ejecting unit 1
There is a risk that the ink of No. 1 will dry and the nozzle will be clogged. Therefore, when the time t or more has passed from the previous printing, the necessity of cleaning the ink ejection unit 11 is recognized first, and then the cleaning is performed for the first time when the need to print the image information by communication arises. To do. Of course, cleaning is performed before printing the image information.

Here, the elapsed time t may be set in advance by the manufacturer, or may be manually set through the operation unit 17. Further, since the elapsed time t may depend on the usage environment of the recording apparatus,
For example, the apparatus itself may be configured to recognize the installation environment by a temperature sensor or a humidity sensor, and t suitable for the environment may be automatically set. In this case, when the time interval T of printing timed by the timer 19 is larger than the set value t, cleaning is performed before printing.

As described above, in the embodiment of the fifth aspect, the ink ejecting section 11 is held for the first time before the cleaning is suspended even if the printing interval T becomes longer than the set time t and printing is performed by communication or copying. Since the cleaning is performed, the number of times the cleaning is performed is reduced and the ink consumption amount is reduced. In addition, since the number of times cleaning is performed can be suppressed, unnecessary electric power is not consumed, and there is an economic advantage together with a reduction in ink consumption.

In the facsimile apparatus using this recording apparatus, when the ink in the ink cartridge 32 is exhausted, the image memory (data memory 22) performs the proxy reception, and the recording and printing are completed after the cartridge is replaced. If the image memory is full before completion,
Refuse transfer or communication and avoid unnecessary communication. If the printing speed is slower than the communication speed, the image memory performs proxy reception while printing and terminates the communication. Alternatively, printing is started after communication is completed, but 1
All the image information obtained by the communication is cleared in the memory after the printing is completed, and if all the information cannot be printed, the memory clear is suspended. After that, the ink cartridge 32 is replaced and printing becomes possible, and when the printing is completed, the memory is cleared manually or automatically.

FIG. 6 is a flowchart showing the operation of the facsimile apparatus shown in FIG. 1. The operation will be described below according to this flow. First, the set value t of elapsed time is compared with the elapsed time T of printing (step S1), and t <T
If so, that is, if t time or more has elapsed from the previous printing, the necessity of cleaning the ink ejection unit 11 is recognized, and the presence or absence of communication (reception) is monitored (step S2), and communication is performed. If there is, the proxy reception is performed in the data memory 22 (step S3), and all the image information received by this communication is stored in the data memory 22 (step S3).
4).

When the image information storage is completed, the ink ejecting section 1
1 is moved to the cleaning unit 15 to perform cleaning (step S5), and printing is started (step S).
6). When printing is performed, the ink end sensor 12 detects whether or not the ink end mark 34 is present at the leading portion of the recording paper 33 (step S7). If not, the number of cleaning executions N (initial value = 0). Is compared with the set value n (step S8), and if n <N, that is, if cleaning has not been executed up to the set number n, the number of executions N is counted up by N + 1 (step S9), and step S5 Return to and perform cleaning again.

On the other hand, if n <N in the determination in step S8, that is, if the cleaning has been performed up to the set number n, the ink end notifying unit 16 notifies the ink end (step S10) and the ink cartridge 32.
It waits for the replacement (step S11). When the ink cartridge 32 is replaced, the process returns to step S6 to start printing.

When printing is started, as described above,
The ink end sensor 12 detects whether or not there is the ink end mark 34 at the leading portion of the recording paper 33 (step S7), and if there is, the printing is continued (step S1).
2) Finish printing one page (step S1)
3). Next, the ink end sensor 12 detects whether or not the ink end mark 34 is present at the trailing edge of the recording paper 33 (step S14), and if there is, the printing for one communication stored in the data memory 22 is completed. It is determined whether or not (step S15). If not completed, the process returns to step S6 to start printing of the next page, but if completed, the image information of the main message is automatically cleared from the data memory 22 (step S16).
The print interval T and the cleaning execution count N, which are measured by the timer 19, are cleared (step S1).
7) and returns to step S1.

On the other hand, the recording paper 33 is judged by the judgment in step S14.
If there is no ink end mark 34 at the rear end portion, the ink ejecting portion 11 is cleaned (step S1).
8) Then, the remaining image information from the next page is printed (step S19). In this case, the cleaning execution count N
Shall not be counted. On the other hand, if t <T is not determined in the determination in step S1, that is, if t time or more has not elapsed from the previous printing, there is no need to perform cleaning of the ink ejecting unit 11, and therefore communication (reception) is performed normally. The presence / absence is monitored (step S20), and when there is communication, the data memory 22 performs proxy reception (step S21), and all image information received by this communication is stored in the data memory 22 (step S22).

When the storage of the image information is completed, the process proceeds to step S6, and the printing process is executed as described above.
