Abstract

PURPOSE:To shift an image area irrespective of a binding form by installing an image output moving means which shifts image information reproduced from a recording medium in accordance with the position of the binding allowance of a recording paper and outputs an image. CONSTITUTION:For instance, in an upper binding mode a preset value 50a is set so that the carrier output C of a preset counter 51 with respect to the image area can delay by 160 lines with respect to a vertical synchronizing signal 49. When the preset value 50a is loaded in synchronizing with the signal 49, the output of a D-FF52 is reset in synchronizing with the signal 49, and a gate circuit 36 is closed up to 160 lines from the signal 49 to stop an image clock 42 to an address counter 33, whereby a memory unit 34 will not act. Due to the rise of the output C a gate circuit 37 is opened, and an image data 46 in synchronizing with a horizontal synchronizing signal 48 is transmitted from the unit 34. Thus a space of 10mm can be formed at the upper side of a copying paper.

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]

When a document copied using a copying machine or the like is bound into a book, the image area formed on the transfer paper is moved to facilitate binding, that is, the document placement position is moved to form the image.

However, in image recording devices that form images by decoding digitized signals, the image forming position on the fed transfer paper is uniquely determined. When recording and reproducing, if the signal from the image reading device is recorded and reproduced as is, the binding margin may not be obtained when binding a book, or the image information at or near the binding margin may become illegible. There were drawbacks such as:

[Purpose of the invention]

This invention was made to eliminate the above-mentioned drawbacks, and by providing an image output moving means for moving image information reproduced from a recording medium according to the position of the binding margin of recording paper and outputting the image, An object of the present invention is to provide an image recording device that can move an image area regardless of the binding format.

Next, the operation will be explained with reference to FIGS. 5 and 6. Note that X indicates the horizontal direction, and y indicates the vertical direction.

FIG. 5 is a schematic diagram for explaining image formation, and FIG. 6 is a timing chart for explaining the operation of FIG. 4.

The addresses of the memory unit 34 are counted in the horizontal direction X by the image clock 42, and are counted line by line in the vertical direction y by the horizontal synchronization signal 43. Further, by resetting the address counter 33, the address of the memory unit 34 returns to the upper left position in FIG.

When reproducing image information, first press switches 38 to 38.
41 is connected to terminal a side, switch 38.39
Image clock 44. A horizontal synchronizing signal 45 is input. At this time, since the switches 40 and 41 are also connected to the terminal a side, the sixth
An image clock 44 as shown in the figure. The horizontal synchronization signal 45 is input to the gate circuits 35 and 36, and the address counter 3
3, an image clock 42 and a horizontal synchronization signal 43 are input. Further, when the switch 41 is connected to the terminal b side, a signal indicating the leading edge of the image sent from the reproduction timing control device 22, that is, a vertical synchronization signal 4

At this point, the memory unit 34 enters the write mode, and the image data 46 sent out from the demodulator 23 in order from the upper left shown in FIG. 5 is stored in the memory unit 34. At this time, the stored image data 46 is stored in the image clock 4
4, one entire page is stored in the memory unit 34.

Next, the image information transfer operation from the memory unit 34 to the image output device 3 will be explained with reference to the time charts shown in FIGS. 7(a) to 7(C). Note that the image information to be transferred includes margin information that takes binding margins into consideration. Furthermore, when creating a binding margin, four modes are possible depending on the position of the binding margin. The first is a left binding mode where the binding margin is placed on the left side of the transfer paper, the second is the right binding mode where the binding margin is placed on the right side of the transfer paper, and the third is the top binding mode where the binding margin is placed on the top side of the transfer paper. , the fourth mode is a standard mode that does not provide a binding margin. Each mode is selected by switching the switch 40.41 and sending a respective counter preset value 50.50a to the counter unit 30.31 in response to a mode command from the system controller 4.

First, the standard mode will be explained. Note that in the standard mode, the switch 40 is connected to the terminal b side, and the switch 40 is connected to the terminal a side.

When outputting image information from the page buffer memory 24, the switches 38 and 39 are switched to the terminal b side in order to switch the clock for reading. At this time,
The image clock 47 for reading is a continuous clock,
Unlike the image clock 39, it is not burst-like. Also, the switch 40 is on the terminal b side, and the switch 40 is on the terminal b side.
Since the terminals o are connected to the terminal a side, the gate circuit 36 is turned ON, and the address in the y direction shown in FIG.
), regarding the address in the X direction, the relationship between the horizontal synchronization signal 48 of the image output device 3 and the image data 46 is that from the horizontal synchronization signal 48 to the image area of the image output device 3, the page buffer memory 24 must stop counting addresses. That is, in the standard mode, the preset value 50 of the preset counter 51 is set to a value such that the carry output C of the preset counter 51 rises at the start time t2 of the image area.
As shown in FIG. 7(b), the gate circuit 35 is turned off for a period of time LM from the rise of the horizontal synchronizing signal 48, and during this time the image clock 47 is not sent to the address counter 33, and the image data 46 from the memory unit 34 is is transmitted so as to coincide with the image area of the image output device 3 at the same time as the gate circuit 35 opens.

Next, a left binding mode in which image data is moved in consideration of the binding margin formed on the left side of the transfer paper will be described.

The resolution of the image output device 3 is, for example, 16 pel(b
1 when handling image data 46 (i t/mm)
When trying to form a 0mm binding margin on the left side of the transfer paper,
Figure 7 shows the reading of 160 bits of image data 46 (
As shown in C), in order to delay between t2 and t3, the preset value 5o of the preset counter 51 is reduced by 160 bits compared to the standard mode, thereby reducing the data high information and memory latched in the D flip-flop 52. Image data 46 stored in unit 34
is output from the gate circuit 37 at time t3 delayed by 160 bits. As a result, a margin of 10 mm is formed on the left side of the transfer paper.

Next, a right binding mode in which image data is moved in consideration of the binding margin formed on the right side of the transfer paper will be described.

The resolution of the image output device 3 is, for example, 16pe 1 (bi
fO+ when handling image data 46 (t/mm)
When trying to form a binding margin of m on the right side of the transfer paper, 16
As shown in FIG. 8, in order to advance the reading of the 0-bit image data 46 by t2-t12 hours, the preset value 50 of the preset counter 51 is set to 1 compared to the standard mode.
By increasing by 60 bits, D flip-flop 52
The data high information latched in the memory unit and the image data 46 stored in the memory unit 34 are 160
It is output from the gate circuit 37 at time t12, which is a bit earlier. As a result, a margin of 10 mm is formed on the right side of the transfer paper.

Next, a top binding mode in which image data is moved in consideration of a binding margin formed on the upper side of the transfer paper will be described. Note that in the top binding mode, the switch 41 is connected to the upper side of the terminal.

As shown in FIG. 9, the image area of the image output device 3 starts immediately after the vertical synchronizing signal 49, which is the leading signal of the image. For this image area, the preset value 50a is set so that the carry output C of the preset counter 51 in the counter unit 32 lags the vertical synchronization signal 49 by 160 lines.
is set. When this preset value 50a is loaded in synchronization with the vertical synchronization signal 49, the D flip-flop
The output of 2 is reset in synchronization with the vertical synchronization signal 49,
Until the carry output C of the preset counter 51 is output, that is, for 160 lines from the vertical synchronization signal 49, the gate circuit 36 is closed and the image clock 42 to the address counter 33 is stopped.
4 no longer works. Then, at the rise of the carry output C, the gate circuit 37 is opened and the image data 46 synchronized with the horizontal synchronizing signal 48 is sent out from the memory unit 34. As a result, a margin of 10ml is formed on the upper side of the transfer paper.

〔Effect of the invention〕

As explained above, according to the present invention, an image output moving means is provided that moves the image information reproduced from the recording medium according to the position of the binding margin of the recording paper and outputs the image, regardless of the binding form. The image area can be moved,
The image can always be output at the optimal position relative to the side where the binding margin is provided. Further, since the width of the binding margin can be increased when binding a book, there are advantages such as ease of binding work.
