Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a copying stage that is particularly applicable to digital copying machines.

[Conventional technology]

2. Description of the Related Art Some conventional copying machines are equipped with a sorter in a paper discharge section of the copying machine in order to sort each document into copies when making copies from a plurality of documents.

[Problem to be solved by the invention]

By the way, the sorter is used to sort copies.
The most common type of copy storage bin is one that moves up and down, has a complicated structure, and requires space on the side of the copying machine to install a sorter.

Therefore, the present invention solves the problems of the above-mentioned prior art,
Another object of the present invention is to provide a copying machine capable of sorting copies without using a sorter.

[Means to solve the problem]

In order to achieve the above object, the present invention provides an image reading means that converts a document image into image information by scanning either the document image or an optical reading device, and an image reading device that converts the read image signal into a main scanning direction perpendicular to each other. An image storage means for sequentially writing and storing an address in the sub-scanning direction, and reading out the stored image signal as appropriate and projecting light onto a photoreceptor to form a visible image on the photoreceptor and transferring it to a recording medium. It has an image recording means, a recording medium size detecting means for detecting the size of the recording medium in the width direction perpendicular to the conveying direction, and a copy magnification setting means, and selects a recording medium of a size corresponding to the copy magnification and performs the above-mentioned In an image forming apparatus that conveys a document to an image recording means and obtains a predetermined image, image information of a plurality of originals at a set copying magnification is sequentially written into a plurality of image storage means, and in the order of writing, a predetermined feed is performed. After transferring to a recording medium of the same direction and size, select a recording medium that differs only in the feeding direction from the transferred recording medium, change the address readout from the image recorder 4g means in accordance with this feeding direction, and select. It is characterized in that it is configured to be transferred to a recorded recording medium.

[Effect]

Since the above method is adopted, if recording media of the same size but different feeding directions are installed, each time the image information is read out from the image storage means, the addresses in the main and sub-scanning directions are sequentially changed depending on the feeding direction of the recording medium. As a result, the recording medium after the transfer changes its direction at the paper ejection unit each time it is ejected.

By connecting each memory circuit of 52(2)...-,
It is possible to write and read a document during A3'#1 feed without waste using 1 tor.

Here, the operation of the above embodiment will be specifically explained.

When the ADF (not shown in FIG. 2) completes feeding the original 2 onto the contact glass l, the reading control circuit 57 shown in FIG. 6 outputs a reading start signal Write. As a result, the image information processing circuit 60 synchronizes with the CCD initialization signal H of the CCD drive circuit 58.
The image information in the main scanning direction of the CD is input sequentially, and the synchronization signal W is input.
, L, 5ync, gate signal for image information in the main scanning direction W, L, Gate, reading start signal W, F, Ga
te, and image information i1W and VD processed based on the input signal of the input means 55 (FIG. 5) are sequentially output.

It is assumed here that the fluorescent lamp 6 is already on, and that the light reflected by the original 2 from the fluorescent lamp 6 forms an image on the CCD element 11 via the lens 4.

Since the first and second scanners 5.8 continuously move in the X direction, the image information processing circuit 60 sequentially processes image information in the main scanning direction (X direction) of the document 2 using the timing cycle of the CCD drive circuit 58. Input, process, and output.

The reading control circuit 57 also operates after measuring a certain period of time based on a signal from a sensor (not shown) that reads the timing until the original 2 from the ADF is set on the contact glass 1, or after a start key (not shown) is pressed. The initialization signal (synchronization signal) of the CCD drive circuit 58 starts counting from the moment the button is pressed.

Of the storage means 52 (1), 52 (2), . . . , writing and reading are performed in the order of 52 (1) to 52 (10) here. The memory control circuit 64 of the storage means 52 receives the read start signals W, F, Gate from the reading means 51.
First, the main scanning address management circuit 61 and the sub-scanning address management circuit 62 are initialized at that edge, in this case set to "0", and the W/R signal is output to switch the synchronization signal switching circuit 69. synchronization signal W from the reading means 51,
L.

The input is switched to Sync input, and the memory circuit 63 is put into the image information writing state. Next, gate signals W and L.

When Gate rises, main scanning address management circuit 6I
Start counting up the address value.

As a result, the memory circuit 63 is stored at the sub-scanning address "0 address".
Gate signals W, L, G from the main scanning address “0” of
By the time ate starts up, the main scanning address management circuit 61 has counted up the image information W,
Burn the VD. Next, synchronization signals W, L, 5y
When nc is input, the sub-scanning address management circuit 62 counts up the address value, and at the same time initializes the main-scanning address management circuit 61, that is, sets it to "0". Also, the gate signals W, L, Gate rise,
Writing is performed in the same manner below. Then, when the address value of the sub-scanning address management circuit 62 becomes "n", the main-scanning address management circuit 61 is initialized, that is, set to "0" in the same manner as described above, and 9pλ is set to the storage means 52 (2). ) is notified that the writing of memory → ÷ 52 (1) has been completed at n, and the next storage means 52 (
2) Outputs a signal NIEXT to notify that writing is to be performed. As a result, the storage means 52(2) initializes the sub-scanning address management circuit 62a, that is, sets the address to "0", and writes the image t+'f +u to its own storage circuit 63a by the cycle of the next synchronization signal. Prepare for.

This operation is performed sequentially up to 1.1 means 52 (10). The storage means 52(1) is 11;1; 4;! r”

When te rises, the main scanning address "0" of the final address "n" of the sub-scanning addresses of the memory circuit 63 is changed as described above.
Writes image information W, VD from address ``to address r'' and ends the write operation (image information processing circuit 60 stops inputting image information to CCD, and sends read start signals W, F, GaLe to storage means 52) ).Then, the output of original 2 is stopped.
is ejected from the contact glass 1, and the next original 2a is
Kick the sensor (not shown) and do the same, this time write t.
This means that the α circuit 63a will be old. Before that, the recording medium 31 that matches the magnification of the original 2 reaches the registration detection sensor 17, and after a predetermined count (the position where the leading edge of the recording medium 31 contacts the photoreceptor 25 and the registration detection sensor 17)
7 is longer than the distance between the contact point and the exposure position for forming a latent image), on the image recording side, the control circuit 71 is connected to the storage means 52 (1) (the storage means 52 (2) and the following are A signal requesting reading of image information (in preparation for writing the original 2a) is output. This signal is stored in the storage means 52.
The memory control circuit 64 of (1) takes the timing of the scanning light from the video control circuit 72 with the synchronization signals R, L, and 5ync consisting of the detection signals of the gJ] detection plate 23, and controls the sub-scanning address management circuit 62 and the main Scanning address management circuit 61
At the same time, a switching signal W/R is outputted so that the output of the synchronizing signal switching circuit 69 becomes the synchronizing signals R, L, and 5ync from the image recording means 54, and the storage circuit 63 is put into a read state, and the image information is R, F, G to notify the start of reading
Output ate. At the same time, the D-F/F circuit 65 is cleared and the selection signal of the selection circuit 66 is set to the B input. The A input is a mode specially used for image editing, and is not particularly relevant to this embodiment.

In other words, the Q output of the cleared D-F/F circuit 65 (
By selecting B, which inputs High II, one input of the AND gate 67 becomes High II, and if the remaining inputs are input, they are input to the latch circuit 68 as they are.

The iron and memory control circuit 64 receive a synchronization signal R; L.

In synchronization with Sync, the gate (No. 3 R, Il, Gate) for outputting the image information R, VD is output. At the same time, the main scanning address management circuit 61 starts counting 7 times. AND gate 67 has an output of 1
Ii5h, the latch circuit 68 is set to the image information output state, and the main scanning address "°" of the sub-scanning address "0" is set.
The image 1n information from "address 0" to "address r" is read out as R and VD.

Subsequently, when the synchronization signals R, L, and 5ync are input, the sub-scanning address management circuit 62 is counted up, the main-scanning address management circuit 61 is initialized at the same time, and the gate signals R, L, and Gate are similarly output, and the image Information 1? , VD are read out sequentially. The video control circuit 72 of the image recording means 54 is
Image information readout start signal R from storage means 52(1),
Input F, Gate, image information and gate signals R, L
, Gate is in the waiting state, and then R, L, Gate
and image information IgR, VD, and manually input them into a toggle buffer memory (not shown). And the next one? , L,
In the cycle in which Gate and image information R, VD are input to another toggle buffer memory, the image information is read out from the previously input 1-toggle buffer memory and synchronized with the synchronization detection signal of the scanning light based on this image information. This modulates the semiconductor laser 18 to create a latent image on the photoreceptor. At this point, the storage means 52(1) also receives synchronization signals R, L, 5ync from the image recording means 54.
Each time you manually input the gate signals R, L, Gate and image information f
IR and VD are output, and the address value of the sub-scanning address management circuit 62 is counted up. Then, when the sub-scanning address value reaches the final value "n address", the storage means 52 sends a signal "NEXT" indicating that reading has ended.
(2), and outputs the image information of the main scanning address "0" to "r" of the sub-scanning address "n" together with the gate signals R, L, Gate, and the next synchronizing signal R, L,
At the time when 5ync is input, read start signals R, F, Ga
Input the output of te. Already before that, storage means 5
2(2) has been completed, the storage means 52
(2) The memory control circuit 63a manually inputs the read end signal NEXT from the storage means 52, and repeats the same procedure with the registration detection sensor 17 signal from the next recording medium 31 as described above.

If the above is normal (the ratio of the size of the recording medium in the transport direction and the size of the original in the sub-scanning (Y) direction, or the ratio of the size of the recording medium in the width direction and the size of the original in the main scanning (X) direction, matches the copy magnification) This is the writing and reading means 111α of the storage means. However, the copy magnification is not the above case, and the ratio of the size of the recording medium in the transport direction and the size of the document in the main scanning (X) direction, or the ratio of the size of the recording medium in the width direction and the size of the document in the sub-scanning (Y) direction. Copying can be performed without any problem even in cases where the values match (in other words, in the case described above, when the recording medium is set in the opposite direction).

The explanation is below.

First, in FIGS. 9(A), (B), and (C), if FIG. 9(A) performs normal sub-scanning of the image and each element is likened to matrix A with main scanning as columns, Matrix B as in FIG. 9(B) or FIG. 9(C)
, C, an image rotated by 90'' can be obtained.

When the size detection of the original document 2 is completed, it becomes clear (in the automatic paper feed selection mode) that there are recording media of sizes corresponding to the copying magnification that differ only in the setting direction. However, when writing, execute it in normal mode as mentioned above (even if you write irregularly from this stage, the result will be the same). The preset f1α of the sub-scanning address management circuit 62 and the main-scanning address management circuit 6I is set respectively according to the output of the signal requesting readout and Req.
', then for matrix B, = ``θ'',! =
r (or for matrix C = n'l
= “0”). Similarly, the memory control circuit 64 is synchronized with the synchronization signals R, L, and 5ync, and outputs gate signals R, L, and Gate for outputting the image information R1VD. Start counting up. As a result, from the sub-scanning address “0” of the main-scanning address “r”
The image information at address "0" is read out as R and VD. In the case of matrix C, the countdown of the sub-scanning address management circuit 62 is started. As a result, the main-scanning address "0" is read out as R and VD.
Image information from sub-scanning address "n address" to "θ address" of "address" is read out as R and VD.

Subsequently, when synchronization signals R, L, and 5sync are input manually, in the case of matrix B, the main scanning address management circuit 61 is counted down, and at the same time, the sub-scanning address management circuit 62 is initialized (returning to the preset value O). Similarly, gate signals R, L, and Gate are output, and the sub-scanning address management circuit 6
Start counting up 2. Similarly, in the case of 71-Rix C, the main scanning address management port &86I is counted up, and at the same time, the sub-scanning address management circuit 62 is initialized (
(return to preset value "n") and similarly, gate signal R1
L and Gate are output, and the sub-scanning address management circuit 62 starts counting down. By sequentially repeating the above steps, the image information can be converted into matrix B or matrix C image information.

The above operations are shown in the timing charts of FIGS. 10, 11, and 12.

Since the configuration is as described above, in this embodiment, "
When you enter "Sort mode" from the operation panel, A (not shown) will appear.
Originals are fed from the DF and sequentially stored in the storage means 52 (1),
Image information is written to 52(2)--, 52(10). At about the same time, a recording medium 31 with a copying magnification of twice the original size is selected, and an image is formed as described above. It is assumed that other recording media 31, which differ only in the feeding direction from this recording medium 31, are set in other paper feed ports 15 and 16. Then, the sheets are sequentially stacked on the paper discharge tray 35.

When the document in the ADF runs out, the end detection signal is activated.
When the final image of the original document 2 is transferred to the iA medium by the photoreceptor 25, this time, only the feeding direction is different: 11; A medium 31 starts in the other direction, and is sequentially transferred.

4. by the Req signal. Images are formed on the α medium 31. By repeating this process sequentially, any number of copies of 10 or less different originals can be made in page order, eliminating the need for a sorter. Of course, the number of original sheets fed from the ADF is 10 or less, and if there are 11 or more, it is sufficient to start repeating once every 10 sheets. Even without using the ADF, from the moment you enter "sort mode" into the operation panel,
Repeat 01 can be started each time the enter key J or the repeat key is pressed after copying from original 2 of 10 sheets or less.

Note that it is necessary to detect not only the size ratio of the recording medium and the document, but also the type (plain paper, tracing paper, etc.) if there is a problem if the types of the recording medium do not match. Furthermore, the same effect can be obtained by using roll paper as the recording medium instead of just paper in the car. However, in this case, unlike the case of sheets, only the size information in the width direction perpendicular to the conveyance direction is given priority (because the length in the conveyance direction can be cut at any position with a cutter). In other words, as long as the ratio of the widthwise size of the roll paper and the size of the original in either the main scanning direction or the subscanning direction does not match the copying magnification, the size in the transport direction can be cut to match the copying magnification of the original. You can get a copy of the image.

The differences from sheet paper will be explained below with reference to FIG. 13. FIG. 13 shows roll paper AI, A2. An embodiment of the image recording means 54 on A3 is shown.

Roll paper A1. A2. A3 size can be set freely depending on the paper quality, paper width, etc. of the recording medium according to the user's preference. Now, roll paper AI, A2. One roll of A3 paper that matches the original size 1X) J? (A20-sized paper is selected for convenience). Since the distance from roll paper A2 to the transfer position is long, immediately after the size of the original is detected,
The driving of the motor 73 of the image recording control circuit 71 of the image recording means 54 shown in the figure is started. As a result, the feed roller pair B2 rotates, and the roll paper A2 with the leading edge aligned is transported immediately after the cutter C2, and when it reaches the sensor G2, the image recording control circuit 71 is configured to count the length of the roll paper A2 being transported. , synchronization signals R, L, 5yn consisting of detection signals of the synchronization detection plate 23 of the scanning light from the video control circuit 72
Start counting c. Subsequently, when the leading edge of the roll paper A2 reaches the registration detection 17, the above-described Req is outputted and a predetermined image is formed.

By the way, the image recording means 54 continues to convey the roll paper A2, and at the same time the image recording control circuit 71 outputs synchronization signals R,
The copy magnification of the length of the document 2 in the main scanning or sub-scanning direction received from the system control means 56 is the value obtained by subtracting the distance between the cutter C2 and the senna G2 from the length calculated from the cycle of 1, ..., 5 sync. When it becomes equal to , the cutter 02 is operated to cut the roll paper A2, and at the same time, the feed roller pair B2 is stopped to complete feeding of the roll paper A2. Incidentally, the sensor F2 detects the length in the width direction, and there are a plurality of sensors in the width direction. In addition, feed roller pair B1 in other roll paper AI, A3. B3, cutter CI, C3
, it goes without saying that the sensors Gl and G3 operate in a similar manner.

Furthermore, this embodiment allows effective use of the recording medium, and can also be used in the following manner. That is, the paper feed port 15 in FIG.
16 or the roll paper AI, A2.
While using any one of A3, the recording medium 31
Even if there is a difference in the width of the roll paper or the setting direction of the cut paper, as long as the recording medium 31 whose two sides of the original 2 match the copying magnification is set, paper can be fed endlessly from there. , you can also get a copy.

Further, even when it is desired to change the feeding direction for each job (copying work) using the input means 55 and set the originals on the paper discharge tray 35, this can be done without changing the orientation of the originals, making later sorting easier.

As mentioned above, storage means 52 (1), 52 (2) 5
When the number 2 (10) is increased, the number of stored original images increases by that amount. Therefore, for example, in the case of 15 copies of 10 originals, if the storage means has 10 or more copies, one copy is stacked on the output tray 35 in page order of the originals, and the next copy is stacked in the direction perpendicular to the direction of the stack. You can stack them, then stack the next part in the same direction as the first one, and so on. Therefore, the purpose can be achieved without installing a sorter (a device for sorting), and it can be simplified using a smaller space.

Although this is the original usage, if there are two or more recording media 31 that correspond to the copy magnification of the original, the priority is given to the one that increases the copy speed (the one that is set horizontally in the IIa feeding direction). Needless to say, it is more advantageous. In the case of roll paper, the copying speed increases when the paper is cut horizontally with respect to the transport direction.

〔Effect of the invention〕

As described above, the present invention can provide a photocopy machine that can stack copies while changing the orientation of each original, and can sort copies without the need for a conventional sorter.
