Description

Description: TECHNICAL FIELD The present invention relates to a recording apparatus provided with recording paper cutting means or page end mark recording means.

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

However, in this case, the recording paper length is irregular on the receiving side and it is difficult to manage, so when the length of the transmitted document is shorter than the preset length, the image signal is transmitted as a white screen for 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.

(Problems to be Solved by the Invention) However, in the above-described conventional example, when recording is continued with white data or black data as long as there is received data,
When the white data portion is long, there is a problem that the recording paper is wasted and the communication time becomes longer, and also that the size of the received recording paper is not constant. Also,
When the image signal is sent as a white screen and the receiving recording paper length is aligned, the size of the receiving recording paper is constant, but when the white data part is long, the recording paper can be wasted and the communication time is long. There is a problem that becomes.

Furthermore, when the receiving side can select whether the recording paper length is to be the end of the received data or a desired fixed length, the state of the image data to be transmitted can be known in advance on 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 problem by determining a recording paper length in accordance with data to be recorded exceeding a designated length of the recording paper.

(Means for Solving the Problems) In a facsimile apparatus of the present invention, as shown in FIG. 1, a recording apparatus using a roll-shaped recording paper and having a recording paper cutting means 1 is provided by a recording paper length designating means 2. First discriminating means 5 for discriminating whether all the data exceeding the designated recording paper length is substantially white data, recording means 6 for recording the number of blank lines, and first discriminating means 5 all substantially. The second discriminating means 7 for discriminating the shorter of the number of white lines and the number of blank lines after recording up to the line where the final black data exists when it is judged that the data is not white data, and the designated length by the first discriminating means 5 When it is determined that all of the subsequent data is white data, the recording paper cutting means 1 is driven by the recording paper length specified by the recording paper length specifying means 2 and the white paper determined to be shorter by the second determination means 7. Recorded at the end of recording the number of lines And a driving means 8 for driving the paper cutting means 1.

When the recording apparatus is provided with a page end mark recording means in place of the recording paper cutting means 1, and the page end mark is recorded at the page end, the driving means drives the page end mark recording means. To do.

(Operation) In the recording apparatus of the present invention configured as described above,
When it is determined that all of the data after the recording paper length designated by the recording paper length designation means is substantially white data, the recording paper is cut at the recording paper length designated by the recording paper length designation means. . As a result, the recording paper lengths are made uniform, and since the recording paper length after the designated recording paper length is substantially all white data, the transmitted information is not lost even if it is not recorded.

Further, when it is determined that all data after the commanded recording paper length are not substantially white data, a white line having a shorter white line number and a margin line number after recording up to the line where the final black data is present. The number will be recorded following the line recording where the final black data is present. As a result, unnecessary white portions are reduced, and recording paper and time are eliminated. Furthermore, it is sufficiently guaranteed even when paper longer than a standard size is required.

The same applies to a recording apparatus that records a page end mark.

The CPU 111, the ROM 112, and the RAM 113 cooperate to perform transmission and reception according to a predetermined transmission / reception procedure according to CCITT recommendations according to a program stored in the ROM, and record information corresponding to the received image data by the printer 16. ,
Drives the cutting unit 15 by the output associated with the status of the output and receive image data from the recording sheet length specifying key 14 ₁ for cutting the recording paper.

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

When the transmission is read by the transmission time of the image reading unit 13, is read out encoded by the image data stored in the image data storage area 113 _1, after data compression modem
Modulated by 12 and transmitted. When receiving the received image data is demodulated by the modem 12, the demodulated data is data decompression, is stored in the image data storage area 113 _1.
Storing the image data is stored is expanded on the recording data in the recording data storage area 113 _2, are read out for each stored data of one line to be supplied to the printer 16 will be 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, the recording sheet length to be cut is designated by the cutting unit 15 in advance by the recording sheet length specifying key 14 ₁ (Step S _1). Image data is received, the recording by the printer 16 of the recording data for one line is performed, the each recorded value stored in the main scan line count region 113 ₃ is +1, the main scanning line number is counted that (step S _2).

Count in step S ₂ is compared with the number of lines corresponding to the recording sheet length specified in step S _1, whether or not it is equal to or greater than the number of the line is checked (step
S _3). In step S _3, the main scan line count area
113 _{value 3} is stored, page end signal when it is determined that the line below the number corresponding to the specified recording paper length is checked whether or not it is detected (step
S ₄ ). Step when no page end signal is detected
Step S ₂ is executed after S _4, when the page end signal is detected cutting portion 15 subsequent to the step S ₄ is driven, the recording paper is cut off (step S _5), 1 page end and Become.

Step value S ₃ in stored in the main scan line count region 113 ₃ is, when it is determined to have reached the above number of lines corresponding to the designated recording paper length, designated subsequently recording sheet length It is checked whether or not all of the print data corresponding to the number of lines or more is white data.
S _6). Wherein 1 when the line is determined to be substantially all white pixels, the value of the white pixel line count area 113 ₄ every time it is judged is +1, and the main scanning line count area in step S ₃ 113 value stored in _3, when it is judged to have reached the above number of lines corresponding to the designated recording sheet length in the main scanning line count area 11
3 Value stored in ₃ and white pixel line count area
The value stored in 113 ₄ has been cleared. Therefore, when the value stored in the value stored in the specified recording sheet length after the white pixel line count area 113 ₄ main scan line count region 113 ₃ are equal, the recording data of the recording sheet length or the number of lines It is determined that all white pixels continue.

When all the data has exceeded the specified number lines line is determined to be white data at step S ₆ is cut portion 15 is driven by the recording sheet length specified by the recording sheet length specifying key 14 ₁ recording paper is cut, the step S ₆ after recording data is discarded (step S _7), a one page completion. Thus, steps S ₂ ~ Step S _4, step
S ₆ , when the step S ₇ is executed, the recording paper length designation key 14
It becomes the recording paper length specified by ₁ . Further, data after the recording paper length is discarded. However, since this case is all white data data after the recording paper length specified by the recording sheet length specifying key 14 _1, there is no problem even if discarded the white data. Further, even if the data in step S ₆ contains black data, if the total number of black data is below a certain value, for example, if that can not form a character is not handled as information is handled as white data Therefore, it is the same as the above case.

Further, the recording sheet length of up to appear page end signal when step S ₂ ~ Step S _4, step S ₅ is executed.

All data exceeds a specified number lines line in step S ₆ is not determined to be the white data, when it is determined to contain black data, a final black data subsequent to the step S ₆ line recording is continued until (step S _8), the final number of black white lines remaining points after the data including the line is checked whether preset by Aru margin setting line number a or (step S _9). In step S _9, when the remaining number of white lines is determined to be less than the number of margin setting line a whole line white recording is performed, after the recording ends, the cutting unit 15 is driven, the recording paper is cut It is (step S _10).

When the number of white lines remain in step S ₉ is judged that there is Te or number margin setting line a is white recording of a line, then cut portion 15 is driven, the recording paper is cut, the remaining white Data is discarded.

Thus, step S _6, steps S ₈ ~ Step S ₁₀
Records but images corresponding to all the image data received on the recording paper length specifying key 14 the length of the recording paper until the line is at least a recording including the last black data than the length specified by ₁ when executed Have been.

Further, step S _6, step S _8, step S _9, to line containing the last black data than the length specified by the recording sheet length specifying key 14 ₁ is recorded when step S ₁₁ is executed, further An image corresponding to all received image data is recorded on a recording sheet having a length in which white data lines of a predetermined margin line number a are recorded.

In the embodiment described above, the cutting unit for cutting the recording paper is used.
Although the case of the facsimile apparatus provided with 15 has been illustrated, in a facsimile apparatus configured to record a page end mark in place of the cutting section 15, in the above-described embodiment, the page end mark is replaced by driving of the cutting section 15. Mark recording may be performed.

(Effect of the Invention) As described above, according to the present invention, when it is determined that all the data exceeding the recording paper length specified by the recording paper length specifying means are substantially white data, the recording paper length specification is performed. Since the recording paper is cut at the recording paper length specified by the means, the recording paper lengths are aligned, and all data exceeding the specified recording paper length is substantially white data, and is not recorded. This has the effect of not losing the information sent.

Further, when it is determined that all data exceeding the designated recording paper length is not substantially white data, the shorter of the number of white lines and the number of blank lines after recording up to the line where the final black data is present. Since the number of lines is recorded, useless white portions are reduced, and there is an effect that recording paper and time are eliminated. Further, even when paper longer than the standard size is required, it is sufficiently guaranteed.

The same applies to a recording apparatus that records a page end mark.
