Abstract

PURPOSE:To partially eliminate the information of an original without the tentative stop of the drive of a photosensitive drum of a printer by inputting a data representing effective elimination, forming a write address synchronously with a line SYNC, eliminating a part of an input original picture data and squeezing the part before and after the eliminated part. CONSTITUTION:When the eliminated region is designated by an operator from an editing data input means 1, a CPU 2 sends a switching signal to a selector 3. Then the selector 3 selects an address outputted from the CPU 2. When the operator applies the operation of the printing start, a data (c) is read sequentially from a memory 4 and inputted to a D-input terminal of a D-FF6. Then an elimination reference signal (d) is outputted from the D-FF6. The signal (d) is inputted to the enable terminal EN of a write address generating means comprising a counter 7 or the like. Thus, the original information is eliminated partially without stopping the photosensitive drum.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an image editing device, and in particular to an image editing device that can edit images at high speed with a simple circuit configuration. .

(Prior Art) As one of image editing, for example, as shown in FIG. 5(a), B information is deleted from a document 31 having A-C information, and the B information is deleted from the document 31 as shown in FIG. There is an image editing method in which A information and C information are combined and printed out.

When performing image editing as described above using a trap copy machine that photoelectrically converts document information and prints it out using a xerography-type printer, conventionally, the scanner side normally uses a laser beam modulated by the document information. Conventionally, a mechanical method was used in which the photosensitive drum was scanned in the same direction, and the rotation of the photosensitive drum was stopped when the laser modulated by the information of the document information B started scanning.

Another method is to write the information of the document 31 into the page memory, delete the B information using software, output the C information next to the A information, and output it to the printer.

In addition, the publication related to the above-mentioned prior art includes Japanese Unexamined Patent Publication No. 59-6
There is a publication No. 2885.

(Problem that the invention attempts to solve) The above-mentioned conventional technology had the following problems.

In the mechanical method of the prior art, the rotation of the photosensitive drum is stopped when the B information arrives, the arrival of the B information ends, and the C
Control is required to restart the rotation of the photosensitive drum when the information begins to modulate the laser beam, and there is a problem in that it is complicated to determine the timing of rotation and stop of the photosensitive drum, and how to synchronize it. .

Additionally, it has been reported that the software-based processing method has a slow operating speed.

The present invention has been made to solve the above-mentioned problems.

(Means and operations for solving the problem) In order to solve the above-mentioned problem, the present invention provides an image editing device that deletes a part of manual original image data obtained by sampling. means for manually inputting data to be represented; a first storage means for storing the data; and the data stored in the first storage means is read out in synchronization with line sync, and the cycle of the line sync is used as a unit. a means for converting the input original image data into a signal; a means for forming a write address based on the converted signal; and a second storage means for storing the input original image data in the write address; The feature is that a part of the file is deleted and the areas before and after the deleted part are packed together.

(Example) The present invention will be explained below using examples. FIG. 4 is an explanatory diagram showing an example of data input means for editing.

In the figure, 30 is a platen glass of the image editing apparatus, and a document 31 is placed on the platen glass 30. Reference numerals 32a and 32b are editing area specifying means for determining the width to be deleted or the width to be printed of the document, and are configured to be slidable by a guide 33. The editing area specifying means 32a, 32b are composed of, for example, potentiometers, and their position information is sent to the CPU using electrical signals.
Sent to 2.

A delete key 34 and/or a print key 35 provided on the panel of the image editing device are connected to the CPU 2, and the CPU 2 is connected to a delete key 34 and/or a print key 35 provided on the panel of the image editing device. You can choose whether to print only the

As shown in FIG. 4, when the original 31 is placed on the platen glass 30 and the editing area specifying means 32a and 32b are adjusted to the B information, the delete key 34 is turned on.
The CPU 2 recognizes that there is a command to delete the B information.

If you want to delete multiple parts of a single manuscript, move the editing area specifying means to other parts of the manuscript you want to delete.
This can be done by turning on the delete key 34.

When the deletion area B of the original 30 is set in this way, the CPU 2 outputs a switching signal, a write signal, an address, and data to the selector 3 and memory 4, as shown in FIG. .

Here, FIG. 1 is a block diagram of one embodiment of the present invention. Further, FIG. 2 shows a time chart of the main parts of the signals shown in FIG. Note that the symbols in FIG. 2 and those in FIG. 1 are written in correspondence.

In the figure, reference numeral 1 indicates an edit data input means as shown in FIG.
sends a switching signal to the selector 3. by this,
The selector 3 selects the address output from the CPU 2. Also, a write enable signal is sent to the memory 4,
The memory 4 becomes writable. Subsequently, based on the deletion area input from the edit data input means 1, the CPU 2 outputs addresses and data as shown in Table 1, for example.

Table 1 Here, "1" in data (D) in Table 1 indicates "effect" and "0" indicates "deletion."

The above address is sent to the memory 4 through the selector 3, and the data is transferred to the memory 4, so the address of the memory 4..., An-2゜An-1
, An, Anal, An+2. The data is stored in =-=.

With the above steps, the setting of the deletion section in the sub-scanning direction of the document is completed.

Next, the operation when printing out the edited image information set as described above will be explained. When the operator performs an operation to start printing from the panel, the CPU 2 determines this and switches the selector 3 to the counter 5 side,
Set memory 4 to read mode. The counter 5 is reset by a page sync PS1 sent from a document reading device (not shown) or the like, and counts the line sync LSI.

Now, suppose that the line sync LS1 as shown in FIG. The count value is the read address AI of the memory 4,
A2. A3. A4゜..., so the addresses are An-2, An-1, An.

Anal, An+2. ......, data C in the figure is sequentially read out from the memory 4, and data D
It is input to the D input terminal of a flip-flop (hereinafter referred to as D-FF) 6. As the clock for this D-FF6, the clock that is inverted from the line sync LSI is input, and at the rising edge of this clock, the data C that is input to the input terminal is latched, so the data C that is input to the above input terminal is latched from this D-FF6. Signal d (second
(see figure) is output.

This signal d is input to an enable terminal EN of a write address generating means constituted by a counter 7 or the like.

When the select signal selects the writing side, the page sync P generated by the document reading device (not shown)
When S1, the line sync LSI, and the sampling clock SC are input to the selector 10, these signals pass through the selector 10, and the page sync PS1 outputs the line sync LSI to the reset terminal R8T of the counter 7 and the timing generator 9. is sent to the clock terminal CK of the counter 7, the reset terminal R5T of the counter 8, and the timing generator 9, and the sampling clock SC is sent to the clock terminal CK of the counter 8 and the timing generator 9.

When the page sync PS1 is input, the counter 7
(high) level period is allowed to count. Also,
The counter 8 is enabled to count while the line sync LS1 is at H level. Further, the timing generator 9 sends a write enable signal WR to the page memory 11 to put the page memory 11 into a write mode.

Now, as shown in Figure 3, the BeigeSync PS
1. Line sync LS1 and sampling clock S
When C is input, counter 7 uses line sync LSI
, and specifies the address of the page memory 11 in the sub-scanning direction. Further, the counter 8 counts the sampling clock SC and specifies the address of the page memory 11 in the main scanning direction. Since the original image data Di is input to the page memory 11 in synchronization with the sampling clock SC, it is stored at the address specified by the counters 7 and 8.

Now, when the deletion reference signal d input to the enable terminal of the counter 7 becomes L (low) level, the counter 7 stops counting the line sync LSI. As a result, the address in the sub-scanning direction does not change, so the base memory 1
The original image data Di is overwritten on the same address of 1.

For example, using the example in FIG. 3, the sub-scanning address A
2 specifies the same address for 4 lines, so 1
Line data L2. L3. L4 and L5 are overwritten, and as a result, one line of data L5 is stored at sub-scanning address A2.

When the deletion reference signal d changes to H level, the counter 7 starts counting again. Therefore, the counter 7 increments by one each time the line sync LSI is manually operated, and the address of the page memory 11 in the sub-scanning direction is A3. A4.
A5. It is incremented as... As a result, the 6.7th, 8th . . . . The data on the line are respectively stored at addresses A3 . . . in the sub-scanning direction of the page memory 11. A4. A5. It will be remembered in...

As described above, according to this embodiment, addresses Al, A2 . A3. A4. A5゜..., data Ll, L5. L6. L7. L8 will be stored.

Next, the operation of reading data stored in the page memory 11 will be explained.

When the page sync PS1 falls, the falling point is detected and a read period begins. The selector 10 outputs a page sync PS2, a line sync LS2, and a video clock V generated by a printer (not shown) in response to a select signal.
Select CK.

Since the timing generator 9 outputs the read enable signal RD, the page memory 11 enters the read mode.

Now, at the timing shown in FIG. 3, the line sink LS2 connects the clock terminal of the counter 7 and the counter
When one value is input to the reset terminal R3T of
The video clock VCK is counted during the H level period. Therefore, the page memory 11 uses the output of the counter 7 to store addresses AI, A2, . A3. A4.・・・
. . . is specified, and the address in the main scanning direction is specified by the output of the counter 8.

At the time of reading, the addresses of the page memory 11 in the sub-scanning direction are specified continuously without interruption, so that the data stored in the page memory 11 is sequentially and continuously read out. Therefore, the output data Do of the page memory 11 is the data Ll, L as shown in FIG.
5. L6゜L7..., data L2 to L4
is deleted, and data L5 is deleted consecutively after data L1.
It is possible to make copies with a printed version.

To explain using the example of FIGS. 5(a) and 5(b), the A information and C information of the document are read out continuously from the page memory 11, but the B information is not read out (1°). If you send the data read from month 1 to the printer and print it out, the B information will be deleted and the A
It is possible to make a copy in which C information is printed next to the information.゛At this time, if the main scanning start of the printer's scanner is made to coincide with the main scanning start of the printer's photosensitive drum, the image shown in Fig. 5(b)
You can make copies like this. On the other hand, if the start of main scanning of the photosensitive drum is delayed by X with respect to the start of main scanning of the scanner, a copy with a white background of length X from the leading edge of the paper as shown in FIG. 6 will be made. I can do it.

Although the above embodiment is an example of deleting several lines in the sub-scanning direction, a person skilled in the art can easily imagine deleting several words in the main scanning direction and filling up the deleted portion, and the present invention within range.

Note that, as the printer applied to the present invention, in addition to the xerography type that irradiates a drum with light to create an electrostatic latent image and develops it with toner, a thermal transfer type or an inkjet type can be used. Furthermore, in the above embodiment, the line sync and sampling clock obtained from the image reading device, and the line sync and video clock obtained from the printer were explained as being independent from each other, but the line sync and sampling clock obtained from the image reading device The sampling clock may be used as the line sync and video clock of the printer, or conversely, the line sync and video clock obtained from the printer may be used as the line sync and sampling clock of the image reading device.

(Effects of the Invention) As described above, the present invention has the following effects.

(1) The system configuration is simplified because it is possible to partially delete document information and fill in the parts before and after it without temporarily stopping the rotation of the photosensitive drum of the printer.

(2) Processing time is short because editing can be done by complete hardware processing rather than by software processing.

(3) Also, since it is not a software process, real-time processing is possible.
