The printer records the image signal from the image processor on recording paper.

[Problem to be solved by the invention]

Incidentally, in the digital image forming apparatus as described above, various image shifting functions are realized by taking advantage of its characteristics. For example, devices have been proposed that have the function of moving an original at any position to any position on transfer paper, or the ability to combine multiple small-sized originals and transfer them onto large-sized transfer paper. There is.

However, with conventional digital image forming devices, for example, when trying to transfer multiple sheets of small-sized documents onto transfer paper of a certain size, first prepare multiple sheets of the same content, and then transfer them to the size of the transfer paper. The operator has to consider the arrangement, triple magnification, etc., in order to transfer effectively accordingly, and this work is very troublesome.

Further, when a plurality of original documents are transferred onto a single sheet of transfer paper, there are cases where it is desired to write a serial number, page number, etc. on each transferred image on this single sheet of transfer paper.

In such cases, in conventional apparatuses, characters such as page numbers are manually written after copying has been completed, and these tasks, along with the above-mentioned document arrangement task, are troublesome tasks.

This invention has been made in view of this point, and when transferring multiple sheets of small-sized originals onto transfer paper of a predetermined size, it is possible to transfer them very easily and by effectively using the transfer paper. The object of the present invention is to obtain a digital image forming apparatus that can perform the following steps.

Furthermore, in the present invention, when a plurality of transferred images are obtained on one sheet of transfer paper, each transferred image has a serial number,
It is an object of the present invention to provide a digital image forming device capable of automatically printing characters such as page number 9 and date.

[Means to solve the problem]

Each one can be printed with a serial number, etc.

[Effect]

In this invention, when there is an instruction to transfer the contents of one document onto multiple sheets of transfer paper, the document size and transfer paper size are first detected, and image forming conditions are input from the operation section. Ru. Then, according to each of the detection results and the designated image forming conditions, magnification, arrangement, etc. when transferring a plurality of documents onto transfer paper are calculated. Next, the image information of the document is read and stored in the image memory. The information in this image memory undergoes a predetermined process based on the calculation result,
The contents are stored in the memory again, and the contents are transferred onto a plurality of sheets of transfer paper at a predetermined magnification and arrangement according to the calculation result.

For example, when the magnification and transfer paper size are input as image forming conditions on the operation section, the arithmetic control section uses the specified size of transfer paper based on the information from the operation section and information on the document size. Calculate the arrangement and number of copies that can be transferred when transferring the original.

Further, 21 is a reading memory that stores image data read by the scanner 12, and 22 is a transfer paper memory that stores image data to be recorded on transfer paper.The image data stored in this transfer paper memory 22 is as follows. For example, it is obtained by subjecting the image data in the reading memory 21 to predetermined arithmetic processing. 23 is a printer control section for controlling the printer section 30; 24 is a writing section for the printer control section 23 and each of the memories 21 and 22;

3. and the control calculation unit 24, the calculation control unit 20
is configured.

Next, we will explain the operation, but since the normal operation is exactly the same as that of the conventional device, we will omit it here. Below, we will explain the operation during editing operation, that is, reading the image information of one document and converting it into a predetermined size. The operation when transferring multiple sheets onto transfer paper will be explained.

When performing the above-mentioned editing operations, various modes can be considered depending on how instructions are given from the operation section, but here, as shown in the flowchart in Figure 3, the transfer magnification and transfer paper size are input from the operation section. Consider a case where the contents of one original document are transferred onto a plurality of sheets of transfer paper in accordance with this instruction.

First, as shown in the flowchart of FIG.
Accordingly, the magnification and the size of the transfer paper are set by the operator (step 51). Next, when the transfer start button is pressed, the ADF II detects the document size (step 52), and this information is input to the control calculation section 24 together with the information from the operation section 14. Based on this information, the control calculation unit 24 calculates how many copies of the original document can be made on transfer paper of the size specified by the operation unit 14 and in what arrangement (step 53).

To explain this in detail using Figs. 4(a) to (6), first, Fig. 4(a) shows the case where form A is copied at the same size onto, for example, A4 size transfer paper. Then, it is calculated that six copies can be made by arranging them all in the same direction. The same figure (b) shows the case of enlarging and copying on the same A4 size transfer paper as described above. In this case, two sheets are arranged in parallel in the vertical direction, and one sheet is arranged in the horizontal direction. The content that the number of copies can be made is calculated. In addition, the same figure (C) is a smaller size than the above (a) and (b), for example, B5.
The same figure (
d) shows a case in which the image is enlarged and copied onto a transfer paper of a larger size than that in (a), and calculation processing is performed so that the transfer paper of each size is used most effectively.

After the arithmetic processing is performed, the image information of the original is read by the scanner 12 (step 54), and the read image data is transferred to the reading memory 21 by the control calculation unit 24 (step 55). The control calculation section 24 transfers the image data to the operation section 14.
The image data is transferred to a predetermined area of the transfer paper memory 22 according to the arrangement determined by the arithmetic processing in step 53 while changing the magnification according to the specified magnification (step 5).
6) When the processes of steps 54 to 56 are repeated for the number of transferable sheets obtained in the calculation process of step 53 (step 57), the control calculation unit 24 sends a print start command to the printer control unit 23. , the printer control unit 23 sends the contents of the transfer paper memory 22 to the printer 30, and image information is printed (step 5).The transfer paper at this time is as shown in FIG.
) to (d).

Next, since ADFII is used in this embodiment, it is determined whether or not there is a next document (same size as the previously transferred document) (step 59). Here, if there is a document, the process returns to step 54 and printout is performed in the same manner as described above.

If there is no document, it is determined whether or not there is any data remaining on the transfer paper memory 22, and if not, the operation is ended. If image data remains in the transfer paper memory 22, the process returns to step 58 to read out the data from the memory 22 and print it out.

In this embodiment, when a plurality of sheets of one document are to be transferred onto one sheet of transfer paper, the number of sheets that can be transferred is as follows.

Since the copying process automatically processes the layout, etc., it is possible to transfer multiple copies of small-sized originals such as forms, cards, business cards, etc. onto one large-sized sheet of transfer paper without the hassle of conventional methods. No work is required, and transfer paper can be used effectively.

In the above embodiment, the magnification and transfer paper size are specified, and the control calculation section calculates the transfer arrangement and the number of sheets that can be transferred onto the transfer paper of the specified size. The contents specified and calculation contents are not limited to the above embodiments. For example, by specifying the number of transfer sheets and the transfer paper size, the appropriate magnification and transfer when transferring to the transfer paper of the specified size are specified. The arrangement may also be calculated. Also, specify the number of transfer sheets and magnification,
The size of the transfer paper and the arrangement at the time of transfer may be calculated, and the transfer paper of the optimum size may be selected accordingly.
The same effects as in the embodiment described above are achieved.

In any of the above cases, if the number of sheets transferred to one sheet of transfer paper is less than the required number of copies, it goes without saying that continuous copying of a large number of sheets is repeated as in a normal copying machine.
For example, if one document can be transferred to five sheets of transfer paper of a predetermined size, and the required number of sheets is 20, the transfer is performed using four sheets of transfer paper of the aforementioned size.

Further, in the embodiment described above, the document size is automatically detected by the ADF, but this may be input by the operator from the operation section.

Furthermore, although the above embodiment does not have a configuration in which the operator checks the calculation results, the calculated number of transferable sheets and transfer arrangement etc. are displayed on a display device, etc., and after the operator confirms the calculation results. , the transfer start button may be pressed. In this way, it is possible to prevent unnecessary transfer due to errors in the calculation results.

Next, FIG. 5 shows a control/block diagram according to an embodiment of the second invention. In the figure, the same reference numerals as in FIG. 2 indicate the same or corresponding parts. 25 is a character font section that stores character information, including image information read from the manuscript, serial number, and page number.

This is for adding character information such as date.

The operation unit 14 in this embodiment includes a print mode selection key for selecting whether to add the character information in an addition mode or a non-addition mode, a print position of the character information, A key is provided for externally setting the printing direction, etc.

Further, the control calculation unit 24 is provided with a counter 24a, and when the addition mode is selected as the print mode, the character information is counted by the counter 24a. The configuration diagram of the main body of the apparatus is the same as that shown in FIG. 1 described above.

Next, the operation of the embodiment shown in FIG. 5 will be explained according to the flowchart in FIG. Note that in this example, A
It is assumed that DFII is not installed. Also, as above,
Let us consider a case where the transfer magnification and transfer paper size are specified from the operation section, and the contents of one original document are transferred onto a single sheet of transfer paper in accordance with the specifications.

The operations up to step 63 are steps 51 to 51 of the above embodiment.
The operation is almost the same as up to 53, but in this example, A
Since the DF is not installed, regarding the reading of the original size in step 62, it is necessary to decide whether to read it with another sensor or to specify printing on the 0th order so that the operator inputs the original size. A determination is made in step 64. At this time, when specifying printing, the start number of printing, the printing direction of one character at the printing position, and the printing mode of addition mode or non-addition mode are set from the operation unit 14 (step 65). By this operation, the start number is initialized in the counter 24a of the control calculation section 24 (step 66).

Next, the document information is read (step 67), and the image data of this document is transferred to the reading memory 21 (step 68). Next, this image data is stored in a predetermined area of the transfer paper memory 22 according to the arrangement that is the calculation result of step 63 while changing the magnification according to the magnification specified in step 61 (step 69). Next, it is determined whether or not printing has been specified (step 70), and if printing is specified, the character font 25 is developed (step 71).
). That is, according to the printing conditions set in step 65, necessary character information is read from the character font 25, and this data is written in a predetermined area of the transfer paper memory 22.

Next, it is determined whether the mode is addition mode or not (step 72).
, in the addition mode, the control calculation section 24
Increment the counter 24a (step 73
), this process is not performed in the non-addition mode, and the processes of steps 69 to 73 are repeated by the number of transferable sheets obtained in the calculation process of step 63.

When it is detected that the processing for one transfer sheet has been completed in this way (step 74), the control calculation section 24 sends a print start command to the printer control section 23, and the printer control section 23 receives the contents of the transfer paper memory 22. is sent to the printer 30 for printing processing (step 75).
).

Although not shown in FIG. 6, the required number of copies is set using the steering knob 61, and the processes of steps 69 to 75 are repeated for this set number of copies. For example, if it is possible to transfer 5 sheets of paper to a predetermined size of transfer paper for 1 original, and the required number of sheets is 20,
The processes of steps 69 to 75 are repeated for four sheets of transfer paper of the above size. When it is detected that this process has completed the set number of sheets (step 76), the operation ends.

A ladder of transfer paper printed by the above operation is shown in FIG. 7 in correspondence with FIG. 4. Note that this example shows a case where the print mode is the addition mode.

In such an embodiment, character information such as a serial number or page number is added to each image on the transfer paper, and the printing position is determined.

Printing can be done automatically taking the direction into account.

Also, if you set it to non-additional mode, you can print the date, etc.

〔Effect of the invention〕

As described above, according to the present invention, the original size and the transfer paper size are detected, a predetermined calculation is performed according to the image forming conditions specified from the outside, and one original is printed at a predetermined magnification based on the calculation result. Since we have made it possible to transfer multiple copies onto a single sheet of transfer paper depending on the arrangement, the operator does not have to consider the arrangement of the originals when making multiple copies of one original, making it easy and convenient. This has the effect of making it possible to transfer using the space of the transfer paper effectively.

In addition, we have provided a means to store text information so that text information can be added to each image transferred onto a single sheet of transfer paper, such as a serial number, page number, etc.
Or, it has the effect of automatically printing the date, etc.
