Abstract

PURPOSE: To produce an optimum binding margin according to an original by providing a copying machine with a moving means moving a copied image in parallel with a copying paper by moving quantity decided according to a position detected by a detection means and a first value. CONSTITUTION: The quantity (b) of the binding margin is read from an operation part. Next, the other set is changed. When a start key is depressed, a CCD set at a stanby position is moved in the (-) direction of an arrow first. When the whole of the original is read, the CCD is returned to the standby position. Thus, a distance (L-a) to a designated position 3 from a reference position H line is measured. Next, the moving quantity (a) of the image is obtained by subtracting some value from the width L of a paper 2. When a copying action is started, the copied image is shifted in the (+) direction of the arrow by the distance (b-a) in comparison with a normal copying action and an area in the (+) direction of the arrow of the designated position 3 is copied as a non-image.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1A is a diagram showing an example of a document 1 copied by the copying machine, and FIG. 2B is a diagram showing an example of a sheet 2 on which the document 1 is copied. is there. The position designation 3 is drawn on the manuscript 1 with a red pen, for example. a is the distance from one end of the original 1 to the position designation 3, and b is the distance from one end of the paper 2 to the position of the position designation 3'on the image copied on the paper 2. However, actually, the position designation 3'is not formed on the copied image. The value of b is named as the binding margin amount and can be input in the range of 0 to 50 mm from an operation panel (not shown) of the copying machine.

FIG. 2 is a vertical sectional view showing the structure of a copying machine according to an embodiment of the present invention. In FIG. 2, reference numeral 4 is a copying machine, which has a document table 5 on which a document 1 is placed. ing. A light source 6 and a CCD (imaging device) 7 are arranged below the document table 5 so as to be movable in the direction of the arrow in the figure. A stepping motor (not shown) serves as a power source for moving the light source 6 and the CCD 7. Reference numeral 8 is a photo sensor for detecting the position of the CCD 7. The position of the CCD 7 can be accurately grasped during movement from the amount of rotation of the stepping motor, with the position where the photo sensor 8 is switched from ON to OFF as a reference position. The reference position is a position where the CCD 7 is located at a position where the line on the one end H of the document 1 on the document table 5 is read.
An optical filter 9 is provided above the CCD 7 so that a red image and a black image can be detected separately.

The moving direction of the CCD 7 is indicated by the arrow in FIG. 2 and represents the same direction as the arrow in FIG. That is, when the CCD 7 moves in the (-) direction of the arrow in FIG. 2, the document 1 in FIG.
It will be read at 7. Therefore, the position a of the position designation 3 drawn by the red pen on the document 1 in the direction of the arrow is scanned and detected once, and the distance a can be obtained. Also, CC
Based on the image read in D7, the laser unit 10 scans and outputs a laser to form a latent image on the rotating photoconductor 11, and the sheet 2 sent from the registration roller 12 starts rotating at a timing. An image is formed.

By shifting the timing at which the registration roller 12 starts to rotate with respect to the latent image on the photoconductor 11, the copy image can be moved in the direction of the arrow. Further, by turning on the laser unit 10 while ignoring the actual image information read by the CCD 7, it is possible to make a specific area on the copy output non-image.

In FIG. 3, 301 is a control means for controlling the entire copying machine 4, 302 is a storage means, which can be changed. In addition, unless changed, the first value which does not change regardless of the turning on / off of the power source and the end of the copying operation is stored. A detection unit 303 detects the position of the position designation image on the image of the document 1. A moving unit 304 is a sheet 2 on which a copy image is copied by a moving amount determined by the position detected by the detecting unit 303 and the first value.
It moves in parallel with respect to. An image non-forming unit 305 does not form an image on one side of the copy image with the position designation image as a boundary.

Next, a series of operations of the copying machine according to this embodiment will be described with reference to the flowchart of FIG. First, in step S401, the binding margin amount b is read from an operation unit (operation panel) (not shown) during standby, and other settings are changed in step S402. Then step S
