Abstract

PURPOSE:To record and deliver through a printer the picture information read assuredly for each page with allotment and even a binding margin, by using a ditital copying machine to read open two pages with just a single scan of a reading optical system for copying of a book, etc. CONSTITUTION:The pictures of a book 1 set on an original glass board 5 are scanned and then read by a reading optical system 8. A printer 24 and a memory 25 are provided. The picture information of the book 1 read successively by the reading scan of the system 8 is converted successively into electric signals with photoelectric conversion by a solid state image pickup element 13. These electric signals are applied to the printer 24 to be recorded on the copying paper P and then delivered or copied after stored temporarily in the memory 25. When the scan is perfomed by the system 8, the n-th page of the book 1 is first read and then the (n+1)th page is read. For this purpose, the center position of a binding margin part 6 of the book 1 is fitted to an original setting standard member 21, and at the same time the book 1 is set on the board 5.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tenkle copying apparatus that converts image information of a book or a similar document into tenotal signals, reads the image information, and copies the image onto copy paper.

Conventionally, when copying a book, etc. using an optical scanning slit exposure copying cloth, as shown in FIGS. The end portion 2 of the document is aligned with the document reference 3, and an optical scanning slit exposure optical system is used as the reading optical system 1 to scan in the direction of the arrow to copy.

Next, the document cover 4 is opened, and the copying process is performed by sliding or rotating the book 1 and copying the (n+1)th page in accordance with the document standard 3. Therefore, the operator has to open the document cup 4 and slide or rotate the book 1 every time, which is very troublesome.

Alternatively, it is also possible to read and copy the nth and n+1 pages of book 1 with one scan of the optical system, and then cut the copied copy paper in half. ．． However,
This copying process is a burden on the operator (this requires extra time and effort).

In addition to this, in recent years, a solid-state imaging device using a charge-coupled device (hereinafter referred to as I-CCU) is used to detect image information as an electrical signal, and then convert it into a Tenkle signal to obtain a read signal. There are known digital copying devices that obtain a copy image from an inkjet printer (based on this reading signal) or a differential printer (such as a Murray J-Heem printer). For example, if two pages, page n and page n4-' of book 1, are read using a solid-state single most imaging element and the reading optical system is scanned twice, It is possible to convert the electric signal as image information into a tental signal, store it in a memory, divide it page by page, and record each page once on a predetermined copy sheet for output.

In other words, the operator's effort in the copying process is halved by the operation of opening and closing the document cover 4 and aligning the position (by turning the page at the first moment without leaving the page containing the image to be copied next). As shown in FIGS. 1(a) and 1(b), 11 is the width of each part of a book with a predetermined width in the scanning direction without copying. When the book was placed face down, the margin part 6 of the book (or manuscript) would float up, making the paper smaller than the specified size.For example, if one page is A5 size book 1 Place the edge of the page with the original standard 3, read the A-1 size (width 2)-4) through the nth page, n4-] page, and read the image as shown in Figure 1 (C). If the read image of page 1 and n 4-] is divided into parts and sent out with a printer recording the specified copy paper number for each page (J No. 11, 1 (C) As shown on the right side, the copy image 7 of page 1 was shifted to one side, resulting in a situation where there was no binding margin at the left end when filing.

In addition, the first copy paper (page Jn and part of page n+1) is recorded and output by the printer, and the second copy paper (page n-) records the remainder of the first page. The present invention has been made in order to solve the above-mentioned drawbacks in view of the points mentioned in "-". It is a digital camera that scans and reads one or two pages at a time with the reading optical system, captures one image for each page, separates the image information, provides a binding margin, and records and outputs it with a splitter. The objective is to provide a copying machine.

Next, the operation of an embodiment of the digital copying apparatus of the present invention will be explained with reference to FIGS. 15 and move it in the scanning direction (direction of arrow 13) or the opposite direction (direction of arrow 13) to determine the appropriate position. Next, when the reading optical system 8 is scanned, the central part lit of the margin 6 of the book 1 is scanned so that the nth page of the book I is read first, and then the n+1 page is read. The book 1 is placed on the document glass table 5'' while aligning it with the reference member 21. As a result, when the document placement reference designating part 21 is moved to the appropriate position as described above, the wire 35 moves, the pulleys 33 and 34 also rotate, and as the pulley 33 rotates, the position of the 1st circle make 22 moves. Since the potentiometer 22 detects the position of the document placement reference designating member 21 by rotating the drawer 22a, the central position of the book 1 can be detected by the output of the potentiometer 22. Also,
When the morph 20 rotates, the pulley 32 provided on the shaft of the morph 20 also rotates, and together with this, the wire 19 moves in one direction when it is stretched, so the tension of the wire 19 causes the movable body to 3B!

Since 16 is rotating, the rotation of C also causes the axis of the tote noyomake 23 to rotate, thereby detecting the position of the reading optical system 1. At the start of scanning, the reading machine starts moving in the scanning direction (direction of arrow A) from near one end of the document table crow 50. Along with this movement of the reading optical system, its position is changed to 11! , and 23 are sequentially output. The difference between the outputs of these two outputs 22 and 23 represents the distance between the document placement reference designating member 21 and the reading optical system, that is, the reading line (2) of the reading optical system.

The copy paper P whose end portion has been conveyed to a position shifted to the 0 side is ejected by an unillustrated ejecting means, for example, a well-known method that includes a light source and a receiving element, and detects the position of the copy paper based on changes in the amount of reflected light. The position is detected by the detection means.

In this way, when the position of the copy paper is detected by the detection means (not shown), the signal of the image information stored in the memory 25 is taken out and applied to the printer 24, and the input array 29 outputs the image information. (Elephant information or copy paper I) ζ

This is because if the width of the blank portion is wide, the edge of the image 7 may not be recorded on the photo paper P.

In the present invention, it is also possible to copy the distributed image information of the nth page and n, +]100th page onto copy sheets l) of different sizes. It goes without saying that the information to be stored in the memory 25 may be stored either on the front side or the rear side of the document placement reference specifying member 21. Further, a plurality of detecting means for detecting the position of the copy paper P as described above are provided, and the length t of the margin can be determined by selecting the detecting means by the operator. You can set it freely, making it easier to use and easier to use. In this case, the normal copying mode and the above-mentioned book copying mode 1- are switched at a point on an operation panel (not shown). In addition, one unit of Plink-24 (various types of I-nodblinks such as an oracer heap printer, a track printer, etc.) may be used.

The present invention is configured and operated as described above, and when copying books, etc., it is possible to obtain copies that take into account the margin, and moreover, two copies of the book, etc. can be made consecutively in one scan. This reduces the burden on the operator by reading the image information on each page and distributing the image information on each copy sheet (6), which reduces the burden on the operator. In order to serve as a designated member or placement reference, the operator is responsible for adjusting the position of the book or checking the effectiveness of the paper.
