When applied to a copying machine with a zoom function, it is necessary to manually adjust the size of the copy paper and the size of the copy paper.
When the copy magnification and copy paper size are set, it is not easy to know whether the entire document will be copied or only a portion of the document will be copied. This may lead to inconveniences such as necessary information not being copied.

Compared to the configuration described in ■ above, the configuration described in ■ and the configuration described in ■ above have the advantage that it is possible to set not only an area corresponding to a standard paper size but also a more detailed area. However, if the copy magnification and copy paper size are set, as in the case of configuration (■) above, either the entire area of the original is copied or only a part of the original is copied. It is not easy to know whether the information is correct or not, and there is a risk that information that needs to be copied may not be copied.

This invention was made in view of the above problems,
It is an object of the present invention to provide a copyable area display device for a document that can display the copyable area of a document, make it easy to grasp the area, and also easily set the area by manual operation. .

The device receives signals from the input device and outputs signals for controlling the copy image forming area.

<Operation> With the above configuration, the size detection means detects the size of the copy paper selected to be used, the copy magnification setting means sets the copy magnification for performing the copying operation, and the size signal is , and the copy magnification signal, the control means calculates the copyable area of the document and outputs a signal for driving a light emitting element corresponding to the copyable area.The light emitting element is driven based on this signal, and the visual The copyable area can be determined by

Furthermore, by manually operating the operating switch, the control means outputs a signal for controlling the copy image forming area based on the signal from the operating switch, and editing operations can be performed based on this signal.

<Example> Hereinafter, embodiments will be described in detail with reference to the accompanying drawings showing examples.

FIG. 1 is a block diagram showing the configuration of a copyable area display device for a document, and shows the operation switches (
1a), the size signal from the size detection section (2), and the copy magnification signal from the copy magnification setting section (3) are applied to the control section (4), and the control signal from the control section (4) is applied to the control section (4). , is applied to the copy processing section (F3J, J3) and the light emitting element (1b) constituting the display body (1).

FIG. 2 is a schematic diagram showing the structure of the display body (1), which is composed of a normally open operation switch (1a) and a light emitting element (1b) consisting of an LED or the like.

FIG. 3 is a plan view showing the state in which the display body (1) is installed, and shows the mutually orthogonal sides (6aH6b) of the document mounting table (6).
A plurality of display bodies (1) are attached in an aligned state close to each other.

Therefore, with the copyable area display device having the above configuration, the copy paper size can be set by operating the paper cassette selection key (not shown), and the copy magnification can be set by operating the copy magnification setting key (not shown). Then, the control unit (5) calculates the copying capacity/rRIpl based on the copy paper size and copying magnification, and calculates the copy size as shown in FIG. As shown in FIG. 2, the light emitting elements (1b) of the display body (1) are made to emit light in correspondence with the copyable area, so that the copyable area can be easily visually confirmed.

Also, by operating the operation switch (1a) of the display (1), the area to be copied is set as shown in FIG. 4 or FIG. 5, and the copy paper nice is set in the same manner as above. If the copying magnification is shifted, the control unit (5) can calculate the copying magnification and perform the copying operation at the optimum copying magnification.

Furthermore, by operating the operation switch (1a) on the display (1), the area to be copied is set with the original (7) set facing upward, as shown in Figure 6 or Figure 7. Then, if you reset the original (force downwards) and set the copy paper size in the same way as above, the control unit (5)
By calculating the copy magnification, it is possible to copy only the necessary portion of the original (7). In this case, the area setting operation for editing is to set the document (7 facing upward and
The actual editing operation is performed with the manuscript (sword) facing downward, so the setting area for editing is as shown in Figures 6 and 7 above. Based on the coordinates X 1.

It is possible to control the timing of the exposure direction. In addition, regarding the length direction of the optical section, a configuration is adopted in which limit switches are attached in correspondence with each display body (1) attached in the same direction.

However, as shown in FIGS. 9A to 9D, instead of driving the switch by physical contact, a light emitting element (1b) that is driven by the operation switch (1a) is attached to the display body (1). The light receiving element (9) integrally attached to the optical part that is not provided may be driven by the operated display (1), so that the timing of the exposure direction can be determined. In addition, in FIG. 9B, the light emitting element (
A light emitting element (1C) dedicated to timing is also attached to the center of 1b).

FIG. 10 is a flowchart for explaining the above-mentioned copy magnification setting function and editing function. In this case, as shown in FIG. A display body having a configuration in which the element (1C) is attached is used.

The copy range determined by the size and copy magnification is displayed, and then in step ■■ it is determined whether the original size has been specified and whether the editing function has been selected. If not, repeat the determination and processing from step ①.

If it is determined that the original size has been specified in the above step (■), all the light emitting elements (1b) are turned off in the step (2), and after the size input is performed in the step (2), the size is input in step (45). After lighting the display light emitting element (1b) corresponding to the point and completing the size input in step @, step @
In step 2, it is determined whether the size input is appropriate or not, and if it is inappropriate, the processing from step (2) onwards is performed again.

If it is determined to be appropriate in step (2), the display light emitting element (1b) of the display body corresponding to the copying range is made to blink in step (2), and the area outside the specified range is made blank in step (2). Determine whether or not is specified, create blank cut data in step [phase] only if specified, and select step @
Determine whether the clear key is ON or not, and turn it ON.
If so, perform the determination and processing following step ① above. If it is OFF, it is determined whether the print key is ON or not in step [phase], and if it is OFF, the determination and processing from step ■ onwards are performed again, but if it is ON, in step ■, the print key is turned on. The copying operation is performed by performing secondary sheet feeding from the position corresponding to the first timing light emitting element (1C), and the determination and processing from step (2) is performed again.

Therefore, as shown in FIG. 12, the copyable range is displayed, and the designated margin area is also displayed.

In this case, the portion corresponding to the diagonal line is formed on the transfer paper as a margin.

If it is determined that the editing function has been selected in the above step ■, the lit display light emitting element (1b) is blinked to display the copy range in step [phase], and the size input is performed in step ■. After that, the display light emitting element (1b) of the display body corresponding to the size input point is turned on in step 2, and after the size input is completed in step [phase], the size input is determined to be appropriate in step O. Determine whether or not, and if it is inappropriate,

If it is determined that the size input is appropriate in step (2) above, it is determined in step (phase) (2) whether the clear key is ON or not, and whether the print key is ON or not. Then, if the clear key is ON, the determination and processing following step ① above is performed, and if the clear key is OFF and the print key is also OFF, the determination in step [phase] ③ above is performed, and the clear key is OFF. If the print key is ON, in step [phase], the first timing light emitting element (1
Editing operations such as trimming and masking are performed from the position corresponding to C) to the position corresponding to the second timing light emitting element (1C), and the determination and processing in step [phase] and subsequent steps are performed again.

Therefore, as shown in FIG. 13, the copyable range is displayed, and the portion designated for trimming, masking, etc. is also displayed. And in this case,
The portions corresponding to the diagonal lines are formed on the transfer paper after being subjected to editing processing such as trimming and masking.
<Effects of the Invention> As described above, the present invention uses a display to display the copyable area determined by the copy paper size and copying magnification, so it can be easily grasped visually. This has the unique effect of making settings and confirmation easy.
