Abstract

PURPOSE:To reduce an image area irrespective of a filing formation by providing an image output reducing means for reducing and outputting the image of an image information regenerated by a recording medium according to a filing position of a recording paper. CONSTITUTION:In order to form a filing section, according to a resolution of an image output device not shown, a reading of an image data 40 stored in a memory unit 32 is delayed by a desired bit time from an image area of the image output device and a clock 42 of a clock cycle thereof shortened 10/9 times comparing with a standard mode time is inputted to an address counter 31. Then, an image data 46 tuning with the clock 42 is outputted to the image output device. Thereby an image reduced to 9/10 of a formed image as a whole is outputted. While a reading of the data 46 is delayed, an image blank signal 45 is fed to the image output device from a gate circuit 35 so as to make a filing section blank.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an image recording device that records and reproduces information on a recording medium using a light beam.

[Prior art and its problems]

2. Description of the Related Art Conventionally, in electrophotographic apparatuses, it is common practice to enlarge or reduce a document on the spot to change it to a desired document size and output an image.

In addition, in an image recording device that outputs image data read by an image reading device, the image data of, for example, an A3 size document read by the image reading device may be reduced to, for example, A4 size recording paper and output as an image. It is designed so that it can be easily performed.

However, when reproducing image data recorded in an image recording device, for example, if the image data recorded in A4 size is outputted onto A4 size recording paper, an image is formed on the entire surface of the recording paper. Therefore, if you want to bind the output document into a book, it becomes impossible to provide a binding margin. For this reason, for example, when playing an image that is formed on the entire A4 size paper, the operator outputs all the pages of the document he wants to play from the image recording device, and then reduces the output image so that the binding margin can be taken again. When reproducing image data that requires bookbinding, time-consuming and complicated operations must be performed, and a large amount of paper is wasted.

[Purpose of the invention]

This invention was made to eliminate the above-mentioned drawbacks, and it is possible to perform binding by providing an image output reduction means that reduces the image information reproduced from a recording medium according to the binding margin position of the recording paper and outputs the image. An object of the present invention is to provide an image recording device that can reduce an image area regardless of the format in which it is stored.

Next, the operation in the standard mode in which no binding margin is provided will be described with reference to FIGS. 4 to 6.

FIG. 4 is a schematic diagram for explaining image formation, where X indicates the horizontal direction and y indicates the vertical direction. Further, FIGS. 5 and 6 are timing charts explaining the operation of FIG. 3.

The memory unit 32 stores one screen of image information as shown in FIG. 4, and the addresses of the memory unit 32 are counted in the X direction by the image clock 36 and in the Y direction by the line clock 37. Also,
When the address counter 31 is reset, the address of the memory unit 32 returns to the upper left position of the screen shown in FIG.

When writing image data 40, switch 33
．． 34 are respectively connected to the terminal a side, and a signal (vertical synchronization signal) indicating the leading edge of the image is sent from the reproduction timing control device 22 to the address counter 31 and reset. At this time, the memory unit 32 is in the write mode, and the image data 4 is received from the demodulator 23.
0 and a write signal from the reproduction timing control device 22 are sent to the memory unit 32, and the image data 4o from the demodulation device 23 is sequentially displayed from the top address of the memory unit 32, that is, from the upper left of the image shown in FIG. The data are stored in the playback page buffer memory 24 in the order of the addresses. At this storage stage, the image data 40 and the image clock 36 have a one-to-one correspondence, and the line clock 36 has a one-to-one correspondence.
7 is also sent out for 1 clock on the 1 line, so all the image information of the entire page is stored in the reproduction page buffer memory 24.

Further, when outputting image information from the reproduction page buffer memory 24 to the image output device 3, the switches 33 and 34 are connected to the terminal b side. At this time, the memory unit 32 is in the read mode. Then, when the line clock 43 as shown in FIG. A clock whose clock within one horizontal synchronization period corresponds to the number of pixels in one line of the reproduction page buffer memory 24 is sent to the address counter 31, and the image data 46 is read out in synchronization with the image read clock 44.

In this way, in the standard mode, image data 46 matching the image area of the image output device 3 is read out from the memory unit 32 by the clock 42, the image read clock 44 and the line clock 43.

By sending the image to the image output device 3, one complete page can be displayed.

Next, the operation in the binding mode will be explained with reference to FIG. 7, FIGS. 8(a) and (b), and FIG. 9. In addition, A
An example will be explained in which a reduced image is output on four sizes of recording paper.

FIG. 7 is a control circuit diagram illustrating the image output reduction means of the present invention, in which 51 is a decimal counter for counting clock signals, 52 is an OR circuit, and the line clock 39 and 1
It is ORed with the carry signal 53 of the 0-base counter 51.

54 is a switch for switching between terminals a and b. 5
5 is a line clock sent from the reproduction timing control device 22.

For example, 211111 in the longitudinal direction of A4 size recording paper.
If you want to create a binding margin of 1, the short direction of A4 size paper is 210 mm, so all you have to do is reduce the entire image to 9/10. Therefore, in the vertical direction, image data 40 is transferred from the demodulator 23 to the memory unit 32.
, the system controller 4 issues a command to the sequence controller 2o of the image storage device 1 to switch the switch 54 to the terminal a side, and the eighth
The line clock 55 shown in FIG. An OR is performed to generate a line clock 39 for writing. Then, as shown in FIG. 8(b), 1 in these 10 clocks.
Since the write inhibit signal 41 is input to the memory unit 32 in synchronization with the line clock 39 whose clock has been thinned out, the writing of the image data 4o is removed once every 10 lines, and finally on 9/10. The data is reduced and input to the memory unit 32. Note that in the standard mode, the switch 54 is connected to the b side, and the line clock 55 is inputted to the address counter 31 as the ink clock 39.

On the other hand, in the horizontal direction, the reduction operation is performed at the stage of transmitting the image information from the reproduction page rough memory 24 to the image output device 3.

First, in order to form the binding margin, the image output device 3
The reading of the image data 4o stored in the memory unit 32 is delayed by a required bit time from the image area of the image output device 3 according to the resolution of the image output device 3, as shown in FIG. The clock 42, which is 10/9 times shorter than that in standard mode, is the address counter 3.
1 is input. Next, image data 46 synchronized with the clock 42 is output to the image output device 3. As a result, an image that is reduced to 9/10 as the entire formed image is output. Note that while the reading of one image data 46 is delayed, an image margin signal 45 (self data) is sent from the gate circuit 35 to the image output device 3 so that the binding margin portion becomes a margin.

In the above embodiment, the case where the binding margin is formed on the left side of the recording paper has been described, but the present invention can be similarly applied even if the binding margin is provided on the right side and the upper part of the recording paper.

[Effects of the Invention] As explained above, according to the present invention, by providing an image output reduction means that reduces the image information reproduced from the recording medium according to the position of the binding margin of the recording paper and outputs the image, it is possible to perform binding. The image area can be reduced regardless of the format in which the image is inserted, and the image can always be moved to the optimal position with respect to the side where the binding margin is provided. Furthermore, since the width of the binding margin can be increased when binding a book, it is not only easier to bind the book, but also the output image is not chipped or difficult to see, and it has the advantage that a clear image output can always be obtained.
