Abstract

PURPOSE:To input original data during image forming operation by storing data in one unit memory area other than a unit memory area being read out for editing operation when data transfer is instructed in operation. CONSTITUTION:A 2nd CPU 22, a 1st memory 23, a 2nd memory 24, and a 3rd memory 25 are connected by a bus line to transmit and receive data. When an end key is operated during copying operation, input editing data is only transferred from the memory 23 to the memory 24 and not transferred to the memory 25. A bit map generated in the memory 25 is not rewritten, so the contents of an editing copy being taken are not changed and no miscopy is caused. Further, new editing data can be inputted even during the copying operation. Further, the input editing data is stored in the memory 24 with an end key, so input operation such as coordinate input is performed efficiently.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an editing input device for an image forming device such as a copying machine.
More specifically, the present invention relates to an editing input device that is capable of inputting data for editing image formation to be executed next during an image forming operation without affecting the image forming operation.

[Conventional technology]

2. Description of the Related Art Conventionally, editing input devices have been provided that are used by being connected to an image forming apparatus, such as a copying machine.

, such an editing input device is a device for inputting editing data.

For example, a manuscript is regulated and placed on a board called a tablet, and the coordinates of the arbitrary point are inputted as editing data by pressing 1 on an arbitrary point. The mode for editing is entered as editing data using a key switch or the like.

Note that, on the copying machine side, editing copying is executed based on the input editing data.

By the way, some of the editing input devices mentioned above do not accept input of editing data while the copying machine is in the process of copying. This prevents the input of edit data from being accepted, so that the contents of the edit copy being executed do not change, thereby preventing errors from occurring in the edit copy.

There is also an editing input device that allows manual input of edited data even during the copying operation. However, in this case, if editing data is input, the contents of the editing copy to be executed will change during the copying operation, resulting in a misprint.

[Problems to be Solved by the Invention] Therefore, in the above-mentioned editing input device, editing data for the next editing copy to be executed is input after waiting for the copying operation of the copying machine to finish. becomes.

However, inputting edited data using presses or key operations on a tablet is a relatively time-consuming task, and if this task is prohibited during copying, the waiting time will be longer.
Work efficiency deteriorates.

The present invention was devised in view of the above circumstances, and
It is an object of the present invention to provide a manual editing device in which editing data to be executed next can be input, and the content of the editing copy being executed does not change during the copying operation.

[Means for solving problems]

When commanded, the original data is converted into editing image forming control data, the converted data is stored in a 10 unit memory area selected according to a predetermined rule, and the above data is stored during the image forming operation. When data transfer is commanded, the data is stored in one unit memory area other than the unit memory area from which the data is being read, and the next data read from the second storage means is selected according to a predetermined rule. An editing input device comprising: data control means for controlling data from a unit memory area;

The configuration requirements will be explained below.

The unit memory area of the second storage means is a memory area that can store one set of data for editing and image creation. Further, data reading means actually executing editing image creation based on the data. - [Example] Hereinafter, the present invention will be described based on a specific example illustrating the present invention.

In the embodiment described below, coordinates are input by pressing a desired point on the tablet, and the erase or trimming mode is performed manually using keys.

Further, erasing or trimming of the specified area is carried out by selectively turning on and off the N+1 LED lamps of the inter-image eraser 4 disposed close to the sensitive drum 61, as shown in FIG. This is achieved by making

It has an LED array 40 in which light emitting elements are arranged in one row,
By selectively causing an arbitrary LED element to emit light with a predetermined amount of light based on data from the second storage means (bit map developed in the memory 25), charging of a corresponding area on the photoreceptor drum 61 is reduced. It is to be removed.

For example, as shown in FIG. 4, codes 0 to N are assumed from the left for N+1 LED elements, and the LED elements are matched to the circumferential speed of the photoreceptor drum 61 based on the data from the second storage means. When the photosensitive drum 61 is turned on and off, the charge in the area of the photosensitive drum 61 corresponding to the shaded area in the figure is removed, and no electrostatic latent image is formed in the area.

(Description of Control Unit) FIG. 5 is an explanatory diagram of the configuration of a control unit of a system consisting of the editing input device and a copying machine.

As shown in the figure, the control section includes a first CPU 21 that controls the main operations of the copying machine, and a second CPU 22 that controls the editor 900 and the eraser 4.

The first CPU 21 receives the key group 20 via the decoder 206.

It is also connected to drivers such as the main motor M1, the developing motor M2, the clutch for the timing roller 73, the automatic paper feed clutch, the electrification charger 65, and the transfer charger 67.

The first cPU 21 controls the main operations of the copying machine, such as driving the image forming section 6 and paper feed/delivery system 7, and adjusting temperature, according to key power or sensor power.

Second CPU 22 inputs coordinate data from tablet 910 via A/D converter 930. In addition, signals from various keys 901 to 904 are input. Furthermore, the second C
The PU 22, the first memory 23, the second memory 24, and the third memory 25 are connected to each other by a path line, and transmit and receive data.

Here, coordinates and mode data input from the editor 900 are stored in the memory.

Further, the second CPU 22 individually controls the light emission of each LED element of the eraser 4 based on the bitmap created in the memory 25 and in response to a command from the first CPU 21 .

Here, the photoreceptor on which the bitmap toner and electrostatic latent image are formed is subdivided in the X and Y directions, and the presence or absence of light emission from each LED element of the eraser 4 for each divided area (pixel) is expressed by ``1'' and 0''. It is something.

FIG. 6 is a drive control circuit diagram of the eraser 4.

As shown in the figure, the drive control circuit includes a shift register 401,
It has a latch 402 and a driver 403, which are connected to the second
Each drive transistor Tr (
0) to Tr(N) are turned on and off.

(Operation Description) The second CPU 22 starts processing, for example, by turning on the power 1, and first sets an initial state (Sl). That is, each condition flag is set to 0 and each memory is cleared. Thereafter, a routine timer that defines the time for one routine is set (S3). Next, the process advances to S5 to activate input/output. Next, in step 87, the En flag is determined. Note that the En flag is a flag that is set by inputting the end key 903.

When the En flag is set, it is determined whether data is stored in the third memory 25 (S9). The third memory 25 is a memory in which a bitmap for controlling on/off of the eraser 4 is developed, and editing and copying is performed based on this memory.

When no data is stored in the third memory 25,
Data and flag contents (E flag or T flag, which will be described later) stored in the first memory 23 are transferred to the third memory 25 by coordinate input, which will be described later (S13).
.

On the other hand, if data is already stored in the third memory 25, the data in the first memory 23 is stored in the second memory 24.
(Sll).

Next, in S15, the En flag is lowered to prepare for re-inputting the end key 903.

In S7 above, if the En flag is not set, it is determined whether or not an electrical signal is input from the tablet (
SIT). 'This is determined based on the presence or absence of a change in the data input from the tablet 91O via the A/D converter 930. If it is determined that there is an input in S17, S
Proceed to step 19 and check the number of presses on the tablet (number of coordinate inputs)
It is determined whether n has reached 2 times. If the value has not been reached, the process proceeds to S21, in which the electric signal generated by pressing the tablet is stored as coordinate data in the first memory 23, and the value of n is incremented by 1 (523), and then the process proceeds to S45. In this embodiment, since the area to be erased or trimmed is specified as a rectangular area, it is sufficient to input coordinates by pressing twice, so the upper limit of n is set to 2.

At step 325, it is determined whether or not the erase key 901 has been input, and if it is determined that "manpower is required", the E flag is set and the T flag is reset (527), and the process proceeds to S45. In the case of "no input", the process advances to S29.

In S29, it is determined whether there is an input to the trimming key 902, and if it is determined that there is an input, the T flag is set and the E flag is reset (531), and the process advances to S45. In the case of "no input", the process advances to S33.

In S33, it is determined whether there is an input on the end key 903, and if there is an input, an En flag is set (S35).

If there is no input, the process advances to S37.

In S37, it is determined whether the clear key 904 has been input. If there is no input from the clear key 904, the process advances to S45. Also, if there is input, it is determined whether or not copying is in progress (539), and if copying is not in progress, the process returns to Sl, and if copying is in progress, the input data (original data) stored in the first memory 23 is "Clear" (341).

Steps 345 to S53 are steps for performing erase control on the designated area. That is, based on the bitmap created in the third memory 25, y=y 1 as shown in FIG.
to y=y2, the LE corresponding to the area x1-X2
By lighting up the D element, (xi, yl)1. (x
2, y2) is fully erased within a rectangular area with vertices of the diagonal line.

On the other hand, steps 354 to S67 are steps for trimming the designated area. That is, between y=yO and y=yn, by turning off the LED elements x1 to x2 from y1 to y2 and turning on the other elements, (XI, yl
), (x2, y2) are the vertices of the diagonal and the area outside the rectangular area is erased.

Next, when the copying operation is completed (369), the data stored in the memory 24 is transferred to the memory 25 and developed as a bitmap (S71). Then, in S73, the process waits for the main timer to end, and returns to S3.

Note that as shown in FIG. 8, the second CPU 22
When there is an interrupt from U21 (S80), the 1st C
It communicates with the PU 21 (S82).

In the above embodiment, even if the end key 903 is pressed during copy <ta collection copy), the input editing data (editing coordinates and editing mode) is not transferred from the first memory 23 to the second memory 24. However, the transfer to the third memory 25 is not performed.

Therefore, since the bitmap created in the third memory 25 is not rewritten, the contents of the edited copy being executed do not change, and no miscopy occurs.

In addition, even during copying, it is possible to input new edited data, and the inputted edited data is stored in the second memory 24 by manual input of the end key 903, so inputting data such as inputting coordinates etc. can be done efficiently.

Note that in the above embodiment, if the number of memories is increased, even more input editing data can be stored.

〔Effect of the invention〕

As described above, according to the present invention, even when data transfer is commanded by the registration designation means during image forming operation, the unit memory being read for editing image forming is Data can be stored in one unit memory area other than the area. Therefore, there is no change in the data contents stored in the unit memory area that is being read out, and therefore, while ensuring error-free editing image creation, the original data can be input during the image creation operation, and the registration designation means This makes it possible to instruct data transfer, making it possible to efficiently input editing data.
