Abstract

PURPOSE:To let a user know the position relation between copying paper and a copy picture prior to copying operation by detecting original size and a platen displacement position and displaying them on a monitor display means, and displaying selected copying paper size thereupon. CONSTITUTION:A display system driving circuit operates in response to a selection of paper feeding by a paper feed selection button or loaded copying paper size detection to display the copying paper size on a copying paper size display panel. On the other hand, a detecting element detects the original size and original position and a display driving circuit operates; when variable power magnification is specified, the variable power mechanism of an optical exposure system operates and information of variable power magnification is inputted to the display driving circuit to display the original size and copying paper size on the display panel. Thus, the picture size and copying paper size are displayed, one over another, on the display panel, so the user makes a position shift manually or by the driving of a motor.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a copying apparatus, and more particularly to a copying apparatus having a movable document table and a monitor display means for displaying the size and positional relationship of the document and copy paper. .

For example, the functions of electrophotographic copying machines have gradually improved in recent years, and now it is now possible to make two copies by selecting from a wide variety of copies of paper loaded in the copying machine. 1 manuscript ((It is possible to change the size, enlarge, reduce the size, and copy 1-4 images. Until now, no consideration has been given to how the image will be co-coated.So what will happen to the image size after scaling compared to the copy paper can be estimated empirically. Copy it once -(-
In situations where you don't know what part of the copy paper you're looking at, even if you change the magnification, it won't match the copy size and will often extend beyond the copy size, or there will be a lot of blank space and you'll have to cut it out. Disadvantage 2: I don't know if the multiplied image will be copied or not
had. In view of such drawbacks, the present invention has been developed.
An object of the present invention is to provide a copying apparatus that allows a user to understand the positional relationship between copy paper and a copy image before copying, and allows the user to correct the positional relationship if necessary. The above purpose is to detect the document size and the displacement position of the document table in a copying machine that is capable of displacing the document table and has a monitor display means, to display C on the monitor display means, and to select it as well. Display the completed copy paper 4 quiz on the monitor display means! -1 advantages are achieved in a copying apparatus characterized by the following features:

That is, the size of the copy paper is displayed on the monitor display, and the size and position of the copy image on the four machines are displayed so that the user can understand at a glance the positional relationship of the copy images. 6, so 1 original set 1'! Displace the platform (!
Then, a change in the position of the visual image is displayed on the monitor display sound 11.

The present invention will now be described in detail using the drawings.

FIG. 1 is a perspective view of a copying apparatus a according to an embodiment of the present invention, and shows a document mounting table, an exposure optical system, a YC body, a charger for charging the photoconductor, and an IJ12 type IJ12 on the photoconductor. ．． a developing device that visualizes the electrostatic latent image, a transfer means that transfers the developed image onto copy paper, a paper feed section that feeds out the copy paper, and a fixing of the transferred image on the copy paper. It has a fuser &λ which is the same as a general copying machine.

In the figure, a document mounting table 1 having an upper surface V is movable in the vertical and horizontal X-Y directions. There is also a monitor display section 2 on the front.
There is. On the right side of the device, various sizes of Kananado 3 are loaded, and the copy paper size can be selected using the paper feed selection button. There is also a variable magnification designation button, which moves the exposure optical system within the apparatus to select variable magnification.

Inside the document table 1, there are a number of detection elements, each of which is a combination of a light emitting element and a light receiving element, for example, and the size of the document is detected by detecting the corners of the document. Similarly, a movement detection member such as a linear encoder is provided inside the document table 1, and the displacement of the document table 1 in the vertical and horizontal X-Y directions is detected.

Next, the monitor display section 2 will be explained. First, regarding the copy paper size, a display panel is provided that displays the outline or area (silhouette) of the copy paper size.

This may consist of a liquid crystal display panel and a drive circuit that drives it, or it may consist of a display panel in which light emitters are arranged in advance in accordance with the size of M paper on a semi-transparent insulating material surface, and this ya' drive lighting. 4-4:
Alternatively, it may consist of a light emitting element arranged in a matrix on a transparent or translucent substrate, a wire through which the light is driven and a circuit, and a circuit.

The light emitting body 21 and its driving circuit 22 are shown.

Next, a display panel was provided to display the outline or area (silhouette) of the original, the size or the size of the image when the size was changed. -4 drive circuit, and a circuit for inputting a signal of the size of the document read by the detection element for detecting the size of the document or of the size changed based on the change-of-magnification command to the drive circuit. .

Separately, a slit-like hole is inserted into the opaque flN, which is illuminated from the back and projected onto a translucent panel through a lens system.
8! It may also be possible to change the magnification ratio according to the magnification change command in conjunction with Ic. The structure of JP-A-55-151 (I62) can also be used in the variable magnification device.

Figure 3 is a diode 7-trinox display circuit diagram, with vertical and horizontal
-Y-axis document→Noise 117 information or magnification (x-y'+*s of 7 sizes is inserted into the terminal, and the diode cap emits light and the outline can be shown.

The non-monitor display section 2 has the above-mentioned compound '1. I: The paper/rize display 2.3 and the WJ image/rise display 24 are superimposed and made into 1-rゎ゜J-'>, which is shown in Fig. 4.

Therefore, the L-user can read the area of the document to be copied from the copy sheet specified by the monitor display.

FIG. 5 shows 1fJ'i of the monitor display section 2. FIG. 5(a) shows that only a portion of the original can be cut into the copy paper. Figure 5(b) Ll, 5th
A first state is shown in which the document table l is displaced in the X-Y direction from the state shown in FIG. 3 so that the document image is copied onto the copy paper.

FIG. 6 is a block diagram showing the display system described above. The display system pN is activated by selecting the paper feed using the paper feed selection button or by detecting the size of the loaded copy paper.

In this way, L7-CK is displayed, and the image size, Cj, and image IZ are respectively displayed on the display panel and the copy paper size display panel, but both panels are superimposed. Therefore, the part of the image that will be copied onto the copy paper is judged by the coach's eyes.

If the user is dissatisfied with this, the position is designated by pressing the manual l) or mode drive button, and the original is placed on the document table 1 in the x-y directions and the displacement of the cover 11 is performed. , the image position is also moved in step 113.

In this way, the present invention has the effect that the image to be copied onto the copy paper 42 can be copied with peace of mind after adjusting the position and size of the image in advance.
