The home position switch 26 is disposed near the boundary between the document placement area 41 and the mark imprinting area 4°, and is located near the boundary between the original document placement area 41 and the mark imprinting area 4°. This is for detecting the second movement origin position of the image reading device 27 relative to the image reading device 27.

As this home position switch 26, like the home position switch 25, for example, a contact type limit switch, a non-contact type reflective photoelectric sensor, or the like is used.

The recording medium 1 is for directly recording a plurality of arbitrary marks, and is composed of, for example, a replaceable resin-based white belt.

Therefore, even if a mark is written on the surface of the recording medium 1 by, for example, a signboard or a stamp, the mark can be erased by wiping it off and can be used continuously and repeatedly.

Further, the recording medium 1 is constituted by, for example, a paper belt,
By replacing the paper heald with a new one after marks have been written on all areas on the recording medium, it is possible to omit the work of erasing marks written on the recording medium.

The recording medium 1 as described above is located outside the original copy area (original placement area 41) of the original presser 5 attached to the original platen 4 and at the home position (first position) of the lamp unit 28 of the image reading device 27. 4. Imprint area of the above mark on the front side in the sub-scanning direction (direction of arrow 6) with respect to the document from the movement origin position). The rollers 7.8 are arranged in an endless manner and run endlessly over a pair of rollers 7.8 arranged oppositely in the main scanning direction of the document. On the document presser 5 corresponding to the upper surface of the recording medium 1, an opening 5 for marking a mark is provided.
The opening 5. When a mark is imprinted on the lower surface side of the recording medium 1 corresponding to the recording medium 1,
A stamp stand 9 that supports the stamp is provided.

Each time the incremental inch 20 is operated, the recording medium 1 corresponding to the opening 51 is moved by a stepping motor 10 that rotationally drives the roller 7.
is sequentially driven in increments for each longitudinal dimension.

In this case, the roller 7.8 and the stepping motor 1
0, the mark moving mechanism 2 is configured to drive the recording medium 1 to move the mark selected by the mark setting means 3 (detailed description will be given later).

The mark setting means 3 selects one or more predetermined marks in a continuous marking area from among a plurality of marks written on the recording medium 1, and the single mark changeover switch 11 and multiple mark selector switch 1
2.

After the single mark changeover switch 11 is operated, a predetermined numbered key of the numeric keypad 13 attached to the recording medium 1 is operated, so that the portion of the recording medium 1 corresponding to the key is operated. The mark drawn in is selected.

On the other hand, when the key corresponding to the first mark in the series of marks and the key corresponding to the last mark in the series of marks are operated after the multiple mark changeover switch 12 is operated, A plurality of consecutive marks within the region are selected.

In this case, a numeric keypad (not shown) provided in advance in the operation panel 14 of the analog image forming apparatus may be used instead of the numeric keypad I3 as described above.

Note that by eliminating the function of selecting two or more predetermined marks in a continuous drawing area as described above and configuring so that only a single mark can be selected at all times, the single mark changeover switch 11 and multiple mark changeover switch 1
2 is omitted.

The above-mentioned magnification ratio specifying means, reference point specifying means, document reading means,
The mark reading means, the control means, the data extraction means 1, the numeric keypad in the operation panel 14, and the control unit 15 that controls the digital image forming apparatus.
This is realized by a processing program etc. stored in advance in the memory 16 of the computer.

The magnification ratio specifying means is for specifying the magnification ratio of the image of the mark with respect to the recording paper, and this magnification ratio is input by operating the ten keys on the operation panel 14.

The reference point specifying means is for specifying a reference point on the recording paper on which the image of the mark is to be recorded, and in the apparatus of this embodiment, it is realized by a position specifying means 19, which will be described later. Incidentally, instead of the above position specifying means 19,
The reference point may be specified in the XY coordinate system by operating a numeric keypad in the operation panel 14.

The document reading means includes the home position switch 2
The image reading device 27 is operated from the first movement origin position of the image reading device 27 detected by the document placement area 4.5. This is for reading the image of the original placed inside.

The control means is for controlling the mark moving mechanism 2 and driving the recording medium 1 to a predetermined position.

In this case, by detecting the reference line 17 provided on the recording medium 1 with, for example, a reflective photoelectric sensor 18,
The initial position of the recording medium 1 is determined. Then, an area where a mark can be written is continuously set with reference to the position of the reference line 17, and by driving the stepping motor 10 in accordance with the size of the writing area N, the opening 51 is inserted into the recording medium 1. The mark drawn on the top is an image reading bag! 27 to a predetermined position where it can be read.

In this case, in place of the photoelectric sensor 18, for example, a CCD that detects the shape of the mark on the recording medium 1 is provided, so that the presence or absence of the mark on the recording medium 1 is determined, and the recording medium 1 is incremented. When moving the mark, the area where the mark has been drawn is skipped and the blank area is automatically filled with the above opening 5. It can be stopped in response to

Further, since the shape of the mark on the recording medium 1 can be directly detected, the position of the reference line 17 is detected by the photoelectric sensor 18 as described above, and the recording medium is
The recording medium 1 can be quickly driven to run to a predetermined position that can be scanned by the lamp unit 28 with reference to the mark 1 without having to drive the mark.

The mark reading means moves the lamp unit 28 of the image reading device 27 from a second movement origin position 1 of the lamp unit 28 detected by the home position switch 26, and moves the lamp unit 28 from the second movement origin position 1 of the lamp unit 28 of the image reading device 27, which is detected by the home position switch 26. The main scanning direction of the image of the mark written on the image reading device 27 and/or the recording medium 1 as appropriate depending on the magnification ratio and the mode based on each data of the reference point specified by the reference point specifying means. This is for adjusting the position of the mask and reading the image of the mask.

The above embodiments include: (1) When the image reading device 27 is adjusted to read the mark image; The movement is adjusted accordingly. The recording position of the image of the mark with respect to the image of the document in the main scanning direction and the sub-scanning direction is set by performing a software synthesis process on data obtained by reading each image.

(2) When reading the mark image by adjusting the position of the mark image in the main scanning direction.In this case, the mark moving mechanism 2 is controlled by the control means to move the recording medium 1 to a predetermined position. The position of the mark image in the main scanning direction is adjusted. The position and magnification in the sub-scanning direction of the image of the mark relative to the image of the document are set by performing a software synthesis process on the data obtained by reading each of the images.

■ When reading a mark image by making the adjustments described in (■) and (■) above. In this case, the control means controls the mark moving mechanism 2, and the variable magnification lens 29, the variable magnification mirror 30, etc. The movement is also adjusted accordingly.

The position of the mark image relative to the original image in the sub-scanning direction is set by software-based synthesis processing of data obtained by reading each image.

■ When an image of a mark is read without making any of the adjustments described in ■, ■, and ■ above. In this case, the mark moving mechanism 2 is controlled by the control means and moved to a predetermined position that can face the lamp unit 28. The recording medium 1 is only driven up to the point where the position of the mark image relative to the original image in the main scanning direction and the sub-scanning direction, as well as the magnification ratio, etc., are determined based on the data obtained by reading each image. It is set by software synthesis processing.

The following explanation will be based on the above case (2).

In the device of this embodiment, "1" is designated by the magnification ratio designation means, or the magnification ratio designation means and reference point designation means are omitted, so that the image of the mark is not scaled. Needless to say, it is possible to record on the recording paper at the same size.

The data extraction means is for extracting the data of the mark image selected by the mark setting means 3 from among the images read by the mark reading means.

The synthesis processing means is for synthesizing the mark image data extracted by the data extraction means and the document image data.

The recording processing means outputs the image data synthesized by the composition processing means in correspondence with the recording position on the recording paper, and performs recording processing.

In the digital image forming apparatus according to the present invention, the recording position of the mark on the recording paper is set so that the recording position (reference point) of the mark on the recording paper can be easily changed as appropriate when performing recording processing by the recording processing means. a position specifying means 19 for specifying, and outputting mark image data extracted by the data extracting means in correspondence with a predetermined position on the recording paper specified by the position specifying means 19;
It also includes other recording processing means for performing recording processing.

The position specifying means 19 includes a tablet placed on the document presser 5, and by specifying a predetermined position on the top surface of the tablet with a stylus, the recording position of the mark is set in the XY coordinate system. Identified by

Incidentally, as shown in FIG. 1(d), in the apparatus of this embodiment, the single mark changeover switch 11. Multiple mark changeover switch 12. An incremental inch 20 that moves the numeric keypad 13 and the recording medium 1 by one pinch (corresponding to the dimension in the longitudinal direction of the opening 51) is provided on the document table 4, separated from the document presser 5. The switch may be arranged on the document holder 5 together with the tablet.

In this case, in the conventional digital image forming apparatus, it is suitable to make the function of imprinting a mark other than the original image onto the recording paper as an option.

Next, based on FIGS. 3(a), 3(a), 3(c), and 3((to)), the procedure for recording an image of a document and an image of a mark on recording paper using the digital image forming apparatus will be explained.

In addition, in the same figure, S1. S2. ...indicates each operation step.

First, a desired mark is manually drawn onto the recording medium 1 through the opening of the document presser 5.

The mark as described above is formed by the opening 5. on the recording medium 1, which is incremented by 1 pitch each time the increment inch 20 is operated. You can make multiple drawings through it.

When a desired mark is drawn on the recording medium 1 as described above, the mark to be recorded on the recording paper is selected at Sl.

In this case, when the single mark changeover switch 11 is operated (Sla), the key number corresponding to the mark to be recorded is pressed on the numeric keypad 13, which indicates the printing order of the plurality of marks. (S1b)
, a single mark to be recorded is selected.

On the other hand, when the multiple mark changeover switch 12 is operated (S
lc), continue to operate the number key corresponding to the first mark in the series of marks on the numeric keypad 13.
ld), and then operates the key number corresponding to the last mark in the series of marks (Sle).

As a result, all the marks within the range specified by the numeric keypad are selected.

In this case, instead of selecting the mark to be recorded by operating the numeric keypad 13, the desired mark is inserted into the opening 5. The desired mark may be selected by moving it to a position that matches the mark and operating a selection switch (not shown).

When a predetermined mark to be recorded is selected as described above, the recording position (reference point) of the mark on the recording paper and the magnification are specified in S2.

That is, first, by operating the numeric keys on the operation panel 14, the magnification ratio (including the case of same magnification) of the image of the mark with respect to the recording paper is specified (S2), and then the magnification ratio of the image of the mark with respect to the recording paper is specified (S2). By specifying a recording position with a stylus, a reference point on the recording paper where the image of the mark is to be recorded is specified in the XY coordinate system (S2).

By making the size of the mark recorded on the recording paper arbitrarily variable as described above, it is possible to maintain an appropriate balance between the image of the mark and the image of the document.

Once the magnification ratio (including the same size) and reference point of the mark image are specified as described above, the document is placed on the document table 4 in S3, and the copy button is operated in S4. Ru.

In this case, the document may be placed on the document table 4 in advance prior to the operation in step S1.

Then, in S5, the recording medium 1 is driven to move by driving and controlling the stepping motor 10.

That is, the mark selected in step S1 above is
It is moved to a position where it can be read by the image reading device 27.

Then, in S6, the home position switch 25
The lamp unit 28 is moved from the first movement origin position detected by the lamp unit 2, and the image of the document placed within the document placement area 4□ is read.

Thereafter, the lamp unit 28 is stopped at - time (
S7. S8).

At this time, if it is necessary to adjust the device based on the variable magnification specified by the variable magnification specifying means and the reference point specified by the reference point specifying means, adjust the variable magnification lens 29 as appropriate. ．． The movement of the variable magnification mirror 30 and the recording medium l is controlled. In this case, the recording medium 1 may be moved in advance before the lamp unit 28 is moved.

Then, the lamp unit 28 is moved from the second movement origin position of the lamp unit 28 detected by the home position switch 26, and the image of the mark is read (S9).

Each data read as described above is temporarily stored in memory. After the image reading operation is completed, the lamp unit 28 of the image reading device 27 returns to the first movement origin position detected by the home position switch 25 (SIO, 5ll).

Subsequently, in S12, the data of the mark image selected by the mark setting means 3 is extracted from the image data temporarily stored as described above, and the data of the extracted mark image and the data of the document image are extracted. are combined and processed.

In this case, in the memory map, the above step S2
The data is processed in accordance with the mark recording position and magnification ratio specified in .

Then, in S13, the image data synthesized in step 12 is outputted in correspondence with the recording position on the recording paper and subjected to recording processing.

That is, the paper feed clutch 21 is turned on at a predetermined timing, and the recording paper is fed toward the recording section.

Then, the image of the document is recorded on the recording paper, and the selected mark is recorded at a predetermined position on the recording paper at a predetermined magnification.

Therefore, in the device of this embodiment, any mark can be printed at any magnification (including the case of same magnification) without replacing the card with the mark imprinted on it as in the case of the conventional device.
The image can be imprinted at a predetermined position on the recording paper very easily.

Furthermore, according to the apparatus of this embodiment, as described above, the lamp unit 28 starts operating from each movement origin position detected by the home position switch 25, 26 in accordance with each image of the document and the mark. It is possible to prevent the image of the mark from being misaligned with respect to the image of the document, which is likely to occur when only the movement origin position detected by the home position switch 25 is used as the movement origin.

As a result, the image of the mark relative to the image of the original document can be positioned on the recording paper with extremely high precision for recording processing.

In addition, in the digital image forming apparatus according to the present invention, as shown in FIG.
By providing this, it is possible to easily visually recognize all the marks written on the recording medium 1 and select a predetermined mark.

Furthermore, in the digital image forming apparatus according to the present invention,
As shown in FIG. 5, the numeric keypad 13 is omitted and a transparent touch panel 24 is provided that allows visual confirmation of all the marks written on the recording medium 1, and the transparent touch panel 24 corresponding to the marks is placed on the transparent touch panel 24. If the configuration is such that a predetermined mark can be selected by manipulating the part, the predetermined mark can be selected more easily.

Furthermore, in the digital image forming apparatus according to the present invention, the main part on the document presser 5 that functions to imprint marks other than the document image including the recording medium 1 onto the recording paper may be detachable.

Furthermore, in the above embodiment, in addition to specifying the recording position of the mark in the XY coordinate system using the position specifying means 19, the mark is imprinted, for example, at the center position in the main scanning direction on the front edge side and the rear edge side of the recording paper. A specific mode may also be provided.

In the digital image forming apparatus according to this embodiment, as described above, by omitting the magnification ratio specifying means, the reference point specifying means, etc., it is possible to obtain a relatively inexpensive configuration that does not have a variable magnification function for mark images. can.
