Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a copying machine, and more particularly to a copying machine provided with a mechanism for monitoring an image from a film projector, and as still another applied technical field, an original monitor device and an original editing device. The present invention relates to a copying machine provided.

A conventional copying machine has a structure in which an original is placed on a platen of the copying machine to make a copy. The structure and operation of such a conventional copying machine will be described with reference to FIG. 12. The image reading unit 2 of the copying machine C50 scans an original while irradiating it and reads the reflected light from the original with a CCD sensor. The image data thus obtained is sent to the image writing unit 4. In the image writing unit 4, the laser beam emits a laser beam according to the strength of the image data.
1, so that the original image is written on the photosensitive drum 61 as a latent image.

Next, the developing unit 62 electrostatically attaches toner to the surface of the photosensitive drum 61 on which the latent image is obtained, and visualizes the original image with the toner. The toner on which the original image is formed on the surface of the photosensitive drum 61 in this manner is electrostatically transferred to the rubber belt at the intermediate transfer portion 63.

In the case of color copying, the steps from the scanning of the document by the image reading unit 2 to the intermediate transfer section 63 are
It is executed for toners of four types of colors of black, cyan, yellow, and magenta. When the process up to the intermediate transfer unit 63 is completed, the paper feeding unit 64 sends the transfer paper to the intermediate transfer unit 63 at the same timing, and electrostatically transfers the toner on the rubber belt onto the transfer paper at once. The transfer paper on which the toner is placed is sent to the fixing unit 65 via the conveyance unit, and the toner heated here is fused and thermally fixed on the transfer paper, and the copying process is completed. The completed color copy paper is ejected outside the machine.

In copying as described above, which is made from a normal original, the original is placed on the original plate of the copying machine and copied. Therefore, the position of the original and the copy paper to be copied are The position of the image that appears is easy to grasp intuitively. Also, the size of the image to be copied can be easily estimated. Similarly, it is easy to check the content of the manuscript.

However, unlike such a normal original, when copying based on an image of a film original projected by a projector or the like, the image is projected while focusing on the contact glass surface on the original table. , It is not easy to estimate the position and size of the image that appears on the copy paper. It is also difficult to easily confirm the image content of the film.

As a method for the user to confirm the film image information, after setting the film on the projector, the lamp of the projector is manually turned on and the image formed on the contact glass is checked to see the film image. There is a thing to confirm the image information. However, it is difficult to observe the image information formed on the contact glass with the naked eye, and therefore a device such as placing a white paper on the contact glass and confirming the image information formed on the paper has been made. However, there is an inconvenience that the operation is very troublesome.

In addition to the above, in the method of confirming the projected image of the film by placing a white paper on the contact glass, it is possible to confirm the positive image (positive image) by the positive film, but in the case of the negative film, the result is confirmed. Since the color information of the image is inverted (complementary color), it is very difficult to confirm the image information of the film. Further, although the image projected from the projector onto the contact glass can be confirmed as described above, there is a problem that it is very difficult to adjust the image of the image to be copied to appear at a predetermined position on the copy sheet.

In particular, when the size of the copy paper is reduced or greatly changed, the user asks at what position on the copy paper the image information of the projected film is copied, or at what size the image appears. However, there is a problem in that there is a large error in the estimation of, and in reality, there is no choice but to rely on an unreliable method of making several copies or more and making a trial and error decision.

Furthermore, the problem of setting the magnification of the copying machine has not been solved. That is, since the image information of the film projected from the projector is enlarged from the film size to a certain size (for example, about A5 size) and projected, when the copy magnification of the copying machine is set to the same size, the designated copy paper is used. A5 size image will be copied. On the other hand, when taking a copy enlarged to the size of the designated copy paper, there is a problem that trial and error and experience must be used to determine the copy magnification on the copying machine side.

The present invention has been made to solve the problems and drawbacks of the prior art, and its purpose is to make it possible to confirm a film projected image by a film projector on a display screen before copying, and to set a negative film. Can display a positive image on the display screen,
In addition, the contour of the specified copy paper and the film image are superimposed and displayed so that the position of the image on the copy paper can be confirmed in advance, and the image magnification can be changed on the display screen.
It is an object of the present invention to provide a copying machine capable of changing the position of an image and making a copy according to the changed magnification and positional relationship.

[0012]

To achieve the above object, a copying machine according to the present invention comprises an image reading unit for reading an image on a document table, a display device for displaying the read image, and a film projector. In a copying machine for forming a projected image by the film projector on the document table and copying the image, a view mode for displaying the projected image on the display device prior to copying is provided.

Alternatively, in the view mode, if the projected image by the film projector is a negative image, it is converted into a positive image and displayed on the display device.

Alternatively, in the view mode, the displayed projection image and the size of the paper to be copied are superimposed and displayed on the display device, so that the position on the paper where the projection image is copied or the image on the paper. It is characterized in that the layout such as the size of is displayed and confirmed before copying.

Alternatively, in the view mode, the correction operation of the magnification and the positional relationship of the displayed effective video image portion based on the superimposed and displayed paper size is enabled, and the correction operation is performed based on the corrected magnification and the positional relationship. It is characterized in that it is configured to be copied.

In the copying machine according to the present invention, the provided view mode is so constructed that the projected image by the film projector is displayed on the display device prior to copying, so that it is easy to confirm the contents and the position dimensions. .
Alternatively, in the view mode, if the image projected by the film projector is a negative image, the image is converted into a positive image and displayed on the display device, and a normal image allows easy-to-see image display.

Further, in the view mode of the copying machine according to the present invention, the projected image and the size of the paper to be copied are superimposed and displayed on the display device so that the position of the projected image on the paper and , It is possible to confirm the display of the layout such as the size of the image on the paper before copying.
