DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a recording paper cutting means,
Alternatively, the present invention relates to a recording apparatus provided with page end mark recording means.

[0002]

2. Description of the Related Art Conventionally, in a recording apparatus using roll-shaped recording paper, for example, a facsimile apparatus, the receiving side has continued to record white data or black data as long as there is received data.

However, in this case, the length of the recording paper becomes irregular on the receiving side, which makes it difficult to manage. Therefore, when the length of the transmission original is shorter than a preset length, the image signal is transmitted as a white screen by the shorter length. In some cases, the recording paper lengths on the receiving side are made uniform. Also provided is a setting means for setting conditions for setting the recording paper length to the end of the reception data or setting the recording paper length to the fixed length. In some cases, it is possible to make selection on the receiving side to increase the degree of freedom in management.

[0004]

However, if the recording of white data or black data is continued as long as there is received data in the above-mentioned conventional example, when the white data portion is long, it can be wasted on recording paper. In addition to the problem that the communication time becomes longer, there is a problem that the size of the received recording paper is not constant. When the image signal is transmitted as a white screen and the length of the recording paper on the receiving side is made uniform, the size of the receiving recording paper is constant, but when the white data portion is long, the paper can be wasted and the communication time Is longer.

[0005] Furthermore, when the receiving side can select whether the recording paper length is up to the end of the received data or a desired fixed length, the state of the transmitted image data is determined in advance by the receiving side. However, there is a problem that which one to select must be determined irrespective of the transmission image data.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a recording apparatus which solves the above-mentioned problems by determining the recording paper length in accordance with data to be recorded exceeding a designated length of the recording paper.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment embodying a recording apparatus according to the present invention will be described below using a facsimile apparatus as an example.

FIG. 1 is a block diagram illustrating the outline of a facsimile apparatus according to the present embodiment.

As shown in FIG. 1, the facsimile apparatus according to the present embodiment cuts a control unit 11, which is a microcomputer for controlling the facsimile apparatus, a modem 12, an image reading unit 13, an operation keyboard 14, and a roll-shaped recording paper 17. Cutting section 15 and a printer 16
It transmits and receives image information.

The operation keyboard 14 is provided with a recording paper length designation key 14a (constituting the recording paper length designation means of the present invention) in addition to a ten-key for dialing. Control unit 11
Comprises a central processing unit (CPU) 111, a ROM 112 storing a program, and a RAM 113 storing image data and other data.

The ROM 112 has a transmission / reception control program for performing transmission and reception in accordance with a predetermined transmission / reception procedure according to the CCITT recommendation, a recording control program for controlling recording of reception information by the printer 16, and a recording paper length designation key 14a. A cutting section drive control program for controlling the driving of the cutting section 15 based on the output from the CPU and the output accompanying the state of the received image data is stored.

In the RAM 113, the transmission image reading unit 1 is stored.
3, an image data storage area 113a for storing the image data read and encoded and the received encoded image data, and recording data obtained by expanding the image data stored in the image data storage area 113a by a character generator (not shown). , A main scan line count area 113c that counts main scans of print data and stores a count value, and pixels that include white data after a designated length and black data below a certain value that cannot be handled as information. A white pixel line count area 113d for counting lines and storing the count value, and a work area 113e are formed.

CPU 111, ROM 112, RAM 11
3 cooperates to perform transmission and reception according to a predetermined transmission / reception procedure according to CCITT recommendation according to a program stored in the ROM, and records information corresponding to the received image data by the printer 16; The cutting unit 15 is driven by the output from the designation key 14a and the output according to the status of the received image data to cut the recording paper.

The operation of the facsimile apparatus according to the present embodiment configured as described above will be described.

At the time of transmission, the image is read by the image reader 13 at the time of transmission, encoded, and stored in the image data storage area 1.
The image data stored in the memory 13a is read, modulated by the modem 12 after data compression, and transmitted.
At the time of reception, the received image data is demodulated by the modem 12, and the demodulated data is decompressed and stored in the image data storage area 113a. The stored image data is expanded into print data and stored in the print data storage area 113b.
The data is read out for each row of stored data, supplied to the printer 16, and recorded by the printer 16. These are similar to the operation of a normal facsimile machine.

Next, the cutting section drive control of the facsimile apparatus of this embodiment will be described with reference to the flowchart of FIG.

For reception, a recording paper length designation key 1
The length of the recording paper cut by the cutting unit 15 is designated by 4a (step S1). Image data is received,
One line of recording data is recorded by the printer 16,
The value stored in the main scanning line count area 113c is incremented by one for each recording, and the number of main scanning lines is counted (step S2).

If the count value in step S2 is equal to step S
The number is compared with the number of lines corresponding to the recording paper length specified in step 1, and it is checked whether the number of lines is equal to or greater than the number of lines (step S3). If it is determined in step S3 that the value stored in the main scanning line count area 113c is less than the number of lines corresponding to the designated recording paper length, it is checked whether a page end signal has been detected. (Step S4). When the page end signal is not detected, step S4 is followed by step S4.
2 is executed, and when the page end signal is detected, the cutting unit 15 is driven following step S4 to cut the recording paper (step S5), and one page ends.

If it is determined in step S3 that the value stored in the main scanning line count area 113c has reached or exceeded the number of lines corresponding to the designated recording paper length, then the designated recording paper It is checked whether or not all pieces of print data equal to or more than the number of lines corresponding to the length are white data (step S6). Here, when it is determined that one line is substantially all white pixels, the value of the white pixel line count area 113d is incremented by one each time it is determined, and the value is added to the main scan line count area 113c in step S3. When it is determined that the stored value has reached or exceeded the number of lines corresponding to the designated recording paper length, the value stored in the main scanning line count area 113c and the white pixel line count area 113d are displayed. The stored value has been cleared. Therefore, when the value stored in the white pixel line count area 113d after the designated recording paper length is equal to the value stored in the main scanning line count area 113c, the print data of the number of lines longer than the recording paper length is all white. It is determined that the pixel continues.

If it is determined in step S6 that all the data of the lines exceeding the designated line number are white data, the cutting unit 15 is driven by the recording paper length designated by the recording paper length designation key 14a. The recording paper is cut,
The recording data after step S6 is discarded (step S6).
7) One page ends. Therefore, step S2
When steps S4, S6, and S7 are executed, the recording paper length is designated by the recording paper length designation key 14a. Further, data after the recording paper length is discarded. However, in this case, the recording paper length designation key 14
Since all data after the recording paper length designated by a is white data, there is no problem even if this white data is discarded. Further, even if the data includes black data in step S6, if the total number of black data is equal to or less than a certain value, for example, if one character cannot be formed, the data is treated as white data without being treated as information. This is the same as the above case.

When Steps S2 to S4 and Step S5 are executed, the length of the recording paper until the page end signal appears is used.

If it is determined in step S6 that all the data of the lines exceeding the designated number of lines are not white data and that black data is included, the final black data is included following step S6. Recording is continued up to the line (step S8), and it is checked whether the number of remaining white lines after the line including the final black data is equal to or greater than a predetermined margin setting line number a (step S9). In step S9, when it is determined that the number of remaining white lines is less than the margin setting line number a, all-line white recording is performed, and after the recording is completed, the cutting unit 15 is driven to cut the recording paper. (Step S10).

When it is determined in step S9 that the number of remaining white lines is equal to or greater than the margin setting line number a, white recording of the a-line is performed, and then the cutting unit 15 is driven.
The recording paper is cut, and the remaining white data is discarded.

Therefore, steps S6 and S8
When step S10 is executed, the image corresponding to all the image data received on the recording paper having at least the length including the line including the final black data longer than the length designated by the recording paper length designation key 14a is recorded. Is recorded.

When steps S6, S8, S9 and S11 are executed, up to a line including the final black data having a length equal to or longer than the length designated by the recording paper length designation key 14a is recorded, and furthermore, a predetermined value is set. An image corresponding to all the received image data is recorded on a recording paper having a length in which white data lines having the number a of blank lines are recorded.

In the above processing, the processing of step S3 functions as the detecting means of the present invention, and the processing of step S6 functions as the determining means of the present invention. Step S7
Functions as the control means of the present invention.

As described above, according to the facsimile apparatus of this embodiment, when the recording data of the number of lines corresponding to the recording paper designated length designated by the designated recording paper length designation key 14a is recorded, the subsequent data is recorded. It is determined whether or not all data is white data.If all data is white data, it is cut at the specified recording paper length, so that the recording paper lengths are aligned, and data exceeding the specified recording paper length is white data. If so, there is no problem without recording.

For example, in the case of a facsimile machine, when a document of one page (tentatively A4) is read obliquely when the document is transmitted from the destination, the length of the document actually read is smaller than the A4 size. Also becomes longer by the amount of skewing. Usually, since the end of the original is often white, the data is transmitted in a state where extra white data is added to the data corresponding to the A4 size original, and the same data is received by the facsimile apparatus. Will be. At this time, if A4 is specified as the recording paper length, conventionally, data equivalent to the original A4 size is recorded and cut, and then extra white data is added, which is substantially unnecessary. Regardless, since recording is performed, recording paper and time are wasted. However, in the case of the facsimile apparatus of the present embodiment, when the data corresponding to the A4 size is recorded, if the subsequent data is white data, the recording is prohibited. It is possible to make the recording paper lengths uniform while eliminating them.

In the above-described embodiment, the facsimile apparatus provided with the cutting section 15 for cutting the recording paper is exemplified. However, the facsimile apparatus configured to record a page end mark in place of the cutting section 15 is used. In the above embodiment, the page end mark recording may be performed instead of the driving of the cutting section 15.
