Abstract

PURPOSE:To prevent an image from being recorded almost in a white state, to legibly observe recorded contents and to prevent recording paper from being uselessly consumped by selecting the data of a prescribed width in a memory based upon the length direction data of the original recorded in the 2nd recording paper or after at the time of detecting that the length of the original is longer than that of the recording paper and executing overlapped recording corresponding to the width data. CONSTITUTION:A central control part 3 is constituted of devices including a line counter 5 and a width data memory 6, and when the image length of an original is longer than the length A of recording paper, recording based upon the image data for A lines is executed and a count value is set up to A/2. Then the number of lines of image data to be recorded in the 2nd recording paper is counted up, and when the original is ended before the count value reaches the length of the recording paper, the end of the image data used for the preceding recording is used by A/2 line to execute overlapped recording. When the count value exceeds the recording paper length, 40% (2A/5) the recording paper length is subtracted from the count value A and the end of the image data used for the preceding recording is used by A/10 to execute overlapped recording. Consequently, recording in the state approximately to pure while can be removed, the recorded contents can legibly be observed and the useless consumption of the recording paper can be reduced.

Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Field of Application) The present invention relates to an image recording device such as a facsimile machine or a copying machine, and more specifically, the present invention relates to an image recording device such as a facsimile machine or a copying machine, and more particularly, the present invention relates to an image recording device such as a facsimile machine or a copying machine. The present invention relates to an image recording device that uses standard paper.

(Prior art) The above-mentioned conventional image recording device has a long original document and is long in the sub-scanning direction.
is longer than the length of the recording paper, simply dividing the original image and recording it may cause problems due to the mechanical characteristics of the image recording device, or because recording is performed on the leading and trailing edges of the recording paper to record pages, etc. In view of this fact, the image portion of the portion related to the division is recorded overlappingly on the front and rear recording sheets.

Specifically, as shown in FIG.
It is stored in 01. Here, the reading unit 402 reads the image data of the document and determines whether recording is on the first sheet of recording paper. If the recording is on the first recording paper, reading continues as it is; if the recording is not on the first recording paper (when the recording is on the second or subsequent recording paper), reading is continued for a predetermined line (d line). ) and performs reading.The image data read by the continuation section 402 is given to the recording section 403, and a recording output based on the image data is performed on recording paper.

However, in conventional image recording devices, the number of lines d for overlapping recording is fixed, so when a document is divided, there is almost no image data on the recording paper of the last page, and it is recorded in an almost pure white state. This may result in images that are difficult to view even though they are recorded repeatedly, or
When the number of lines d is large, there is a problem in that the recording paper is wasted.

(Problems to be Solved by the Invention) As described above, with conventional image recording devices, the number of lines to be recorded repeatedly is fixed, so recording may be performed in an almost pure white state, making it difficult to see or However, there was a problem in that recording paper was wasted.

The present invention was made to solve the problems of conventional image recording devices, and its purpose is to eliminate recording in an almost pure white state, thereby making it difficult to look at the image, and An object of the present invention is to provide an image recording device that can reduce waste of recording paper.

[Structure of the Invention] (Means for Solving the Problems) In the present invention, an image recording apparatus that performs recording based on image data of a document using a recording paper having a predetermined length in the sub-scanning direction has the following features: a memory storing a plurality of width data of widths to be repeatedly recorded on the recording paper when the document is longer than the document length; a detection means for detecting data related to the length direction of the document; If it is detected that the document is longer, select predetermined width data in the memory based on data in the length direction of the document recorded on the second and subsequent recording sheets detected by this detection means, The image recording apparatus is equipped with recording control means for performing overlapping recording corresponding to this width data.

(Function) According to the above structure, a plurality of width data of the width of the overlapped portion in the case of overlapping recording are stored, and the data in the length direction of the document recorded on the second and subsequent sheets of recording paper, that is, The width of the overlapping part can be selected depending on the length of the remaining divided parts of the original to be recorded, so by increasing the width of the overlapping part, recording in a nearly pure white state can be eliminated, or the above It is also possible to narrow the width and allocate the image that was conventionally recorded on the last page to the previous page.

(Example) An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of a facsimile machine that is an embodiment of the present invention. In the figure, 1 indicates a line, and 2 indicates a communication control section. The image data of the document arriving via the line 1 is received by the communication control section 2, demodulated, and sent to the central control section 3. The central control unit 3 controls the facsimile machine in an integrated manner, decodes and expands the image data given above, and stores it in the image memory 4. In addition, when recording and outputting, the central control unit 3 stores the image data of the document in the image memory 4.
The data is read out and applied to the line counter 5. Although the image data has an EOL (end of line) at the end of one line, the line counter 5 counts the EOL and provides data on the number of lines to the central control unit 3 together with the image data. A width data memory 6 is connected to the central control unit 3, and a plurality of width data of the overlapped recording portion are stored. Here, the recording paper of the facsimile machine is standard paper with a length of A in the sub-scanning direction, and the width data is A/2, A/10.
Suppose that is used. The central control unit 3 functions as a recording control means 31, and when the number of lines of image data to be recorded on the second and subsequent sheets of recording paper is less than A/2, A/2 is adopted as the width data, and A/2 is used as the width data. If it is 2 or more, A/10 is adopted as the width data. The recording control means 31 provides the recording unit 7 with the image data of the A line including the image data for this time in addition to the image data used previously for the number of lines corresponding to the adopted width data. As a result, it is possible to prevent printing output in a nearly pure white state, and waste of printing paper is eliminated.

Generally, the central control unit 3, which is composed of a microcomputer or the like of a facsimile machine, includes a line counter 5 and a width data memory 6, and the flowchart shown in FIG. 2 stored in the main memory. Execute the program to control recording.

That is, the length of the transmitted manuscript is counted (S20
1) Detect whether M draft is finished (S202).

If the process ends here, the image of the document will fit on the recording paper, so it will be recorded as is (S203). If the document does not end, it is detected whether the recording paper length is longer than A (S204). Here, if it is not long, the process returns to step S201, but if it is long, recording is performed based on the image data for A line, and the count value is set to A/2 (50% of A) (S205). Furthermore, the number of lines of image data to be recorded on the second recording paper is counted (S2f) 6),
It is detected whether the document is finished (S207), and if it is not finished, it is detected whether the count value is greater than the recording paper length A (8208), and the image data is A/2.
It is detected whether the value is less than or equal to the value, and the process returns to step 8206. If the document ends before the count value reaches the recording paper length, redundant recording is performed using the end of the image data used for the previous recording for A/2 lines (S209). On the other hand, if the count value exceeds the recording paper length, 40% of the recording paper length is calculated from the count value (A).
Subtract (2A/5) (S210), continue counting the number of lines of remaining image data (8211>, detect whether the document has ended or not (S212), and if it has not ended, the number of lines is greater than the recording paper length A. By detecting whether the count value has been reached (S213), it is detected whether the image data exceeds 9 A/10, and the process returns to step S211. In addition, if the document ends before the count value reaches the recording paper length in step S212, the end of the image data used for the previous recording is
Duplicate recording is performed using /10 lines (S214). On the other hand, if the count value exceeds the recording paper length, redundant recording is performed using the end A/10 line of image data used for the previous recording, and the count value is set to A/2 (S21
5), return to step 20G and operate.

By performing such an operation, a document P whose document length 1 is A<f<3A/2 as shown in FIG.
1 image data is given, the first recording paper S
An image having an overlapping area of A/2 is recorded on the first and second recording sheets S2, making it easier to read compared to conventional recording in an almost pure white state.

Also, the document length l as shown in Fig. 3 (B>) is 3A/
2<, (<2A) If the image data of the original P2 is given, the first recording paper S3 and the second recording paper S
4, an image having an overlapping portion of A/10 is recorded.

Therefore, when the width data is set to only A/2, it is possible to prevent the recording paper from being divided into three sheets and wasting the recording paper.

Note that there may be three or more types of width data.

[Effects of the Invention] As explained above, according to the present invention, since there is a plurality of width data for overlapping recording, the width of the overlapping portion is determined depending on the length of the remaining portion of the document recorded on the second and subsequent sheets of recording paper. This eliminates recording in an almost pure white state, making it easier to see and preventing waste of recording paper.
