Reference numeral 87 indicates a pickup roller for taking out the recording medium (hereinafter referred to as copy paper) 811 stored in the paper feed force cellar h811 one by one, and 812 to 815 indicate transport ix rollers provided on the copy paper conveyance path. On the other hand, 816 is a transport belt for discharging the recorded copy paper, 88 is a fixing roller installed near ()1 output roller, and 89 is a belt for stacking the discharged copy paper. -It's Leh.

FIG. 4 shows an example of a control procedure according to this embodiment, and the operation of the above configuration will be explained using this figure.

First, when the power switch (not shown) is inserted, the CP
In the old version, a predetermined initial setting routine (step S1) is executed, and after the fixing roller 88 reaches a predetermined temperature, the system waits for a command from the keyboard 4 (step S3).

When the operator instructs the °C copying operation using the keyboard 1, the CP old drives the image reading means 6 to take a °C copy image (step!+5). This image reading is performed four times by switching the color filter, and the image is developed in the image memory 7V for each color (yellow, magenta, cyan, black).

Next, the money detection means 9 is activated to check whether the image data on the image memory 7 is money or securities (
Step 57). In this embodiment, if there is an address correspondence between the readable area on the document table 64 and the storage area of the image memory 7, then the size of the data development area on the image memory 7 is jl(). The inspection can be performed by recognizing the size of the original and comparing the result with the size of currency, etc. stored in advance in the ROM 2 etc. Also, the color spectrum distribution of the original 81 can be registered in advance. It is also possible to compare J: with data that is.

In step 2, if the size corresponds to the size of money, etc., the money detection means outputs 1°°, and if it does not correspond, it outputs "o". For the old CP, if this output is 0°, it is ll!'!
The IdII image on the image memory 7 is outputted as a color image by the output means 8 (step 511). - force, °
If “1”, image output is prohibited (step 513)
.

1 flesh image output processing (step 511), the well-known still image output process (step 511)
Image formation is performed based on the L process. That is, after charging the photosensitive I-ram 86 to -11 (:) with the primary charger,
1. In synchronization with the rotation of the photosensitive tram 86. The E lower array 82 is blinked in accordance with image data to form an electrostatic latent image.

This electrostatic latent image is developed with a developer (toner, etc.) in a developing device 83, and is picked up by a transfer charger 84.
The image is transferred onto the fed copy paper 87. To output a color image, use the above process to output yellow, magenta, cyan,
This is achieved by performing this for each color of black. After the development of the predetermined color is completed, the copy paper 810 is delivered to the transport bell! -816, the paper is conveyed to rollers, thermally fixed, and outputted to tray 89.

Conversely, in the process of step S13, the old CP does not activate the image output means 8, so copying is prohibited and no output is made. 1- That is, if the document is currency or the like, image output is prohibited. It is also possible to open this process and display a predetermined error message or issue an audio warning.

In order to finally prohibit the output of images of money and the like in this manner, in addition to prohibiting the operation of the image output means 8 as described above, it is also possible to prohibit the operation before that. For example, the document surface is scanned four times for each color, but if the document size becomes clear in the process, image output may be prohibited by prohibiting further reading at that point. .

Further, it is also possible to configure the image outputting means 8 to be configured to be prohibited from outputting after the copying operation.

FIG. 5 shows such an embodiment. In this embodiment, the copy paper on which the image has been formed is not outputted to the outside of the apparatus, but is cut and cut internally. This means that only one shot will be discarded.

FIG. 5 shows a schematic configuration of the main parts of this embodiment, and in this embodiment, regardless of the type of document, the process proceeds up to image transfer to copy paper as in the embodiment shown in FIG. When the output of the image detection means 9 is 0°', the transport belt 816 is set at the position indicated by the solid line in FIG. After being conveyed to rollers 88 and thermally fixed, it is output to a paper discharge tray 89. 1. On the other hand, if the output of the image detection means is 1°', 1-, that is, if the original is a currency or the like, the conveyor belt 816 is set at the position indicated by the broken line in FIG. Then, the sent copy paper 810 passes through the guide 100 and is sent to the cutting machine 101, where it is cut into small pieces and discarded, so that no copy output can be obtained.

In each of the embodiments described above, the detection of whether the document is currency or not is performed based on the document size, but such detection may be performed using any form of means. Ino is of course.

For example, a device may be provided that reads the magnetic pattern of a part or the entirety of a coin used in a vending machine or the like, and the pattern may be stored in advance and compared with a certain pattern. In this case, a configuration in which a magnetic head A is provided on a document cover that is not provided on the document table 64 and covers the document 69,
Alternatively, if the copying apparatus is equipped with an automatic document feeder (ADF) or the like, a magnetic head may be provided on the conveyance path.

It is also possible to read the image pattern of a part or the whole of the currency and compare it with a pre-stored pattern. For this reading, if the device is in the form of a digital copying machine as described above, the reading operation by the image reading means 6 may be used as is, or if it is not, a reading head may be provided on the conveyance path of the document cover or ADF, etc. Just leave it there. Alternatively, an illumination means may be provided on the document cover to read the watermark pattern and perform the comparison.

Furthermore, it goes without saying that the present invention can be applied regardless of the form of the image output means 8. For example, in Example 1, an LED array was used to form an electrostatic replacement image on the photosensitive drum, but even if a laser beam or other device is used, J:<, and V are those. J: It is not limited to the electrophotographic method, and C may also be used, as it may use various methods.

[Effects of the Invention] As explained above, according to the present invention, when an attempt is made to copy something that is prohibited from being copied, such as money or securities, this fact is detected and the copy is not output. This has the effect of preventing counterfeiting.
