Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an image processing apparatus that can set a plurality of magnification ranges using the same magnification setting means.

[Prior art and its problems]

Conventionally, this type of apparatus has been configured so that settings from reduction to enlargement can be made continuously using a single magnification setting lever. With this method, you can set the magnification simply by moving the magnification setting lever, but as the magnification setting range increases, the movable range of the magnification setting lever is constant, so if you want to set the magnification within a specific range, operate the magnification setting lever. becomes significantly difficult. For this reason, some models allow you to select the magnification setting range according to the magnification, but for example, if the magnification setting range is 60%
~70% of models, after making 70% copies, 71
If you try to copy %, you need to select a magnification setting range that is higher than that class. In this way, if you try to set a magnification that is slightly outside the upper or lower limit of the magnification setting range, you have to select the magnification setting range again, which has the disadvantage of making the magnification setting operation very time-consuming. .

[Purpose of the invention]

This invention was made in order to eliminate the above-mentioned drawbacks, and the magnification setting range is divided into multiple parts, and the upper limit of each divided magnification setting range is located at the middle value of the upper magnification setting range. An object of the present invention is to provide an image processing device that can be configured and efficiently perform magnification setting operations.

It consists of 11c. Magnification area display 11a.

11b and llc each have a reduction ratio of, for example, 60% to 8.
Divided transfer magnification areas of 0%, 70% to 90%, and 80% to 100% are displayed. Furthermore, an LED or liquid crystal is used for this display. 12 is a reduction magnification selection key corresponding to the area selection means of the present invention; 13 is an enlargement magnification selection key; 14
is a numeric keypad for setting the number of transfer sheets, a portion of which is shown below.

It should be noted that the area selection means of the present invention is operated by the enlargement magnification selection key 13.
However, for convenience of explanation, the reduction magnification selection key 12 will be explained.

Next, the operation will be explained.

When the power is turned on, the transfer magnification is automatically set to the same magnification (100%), and each magnification area display 11a of the magnification area display section 11
, 11b and 11c are off.

If the operator wishes to make a copy with a reduction ratio of 70%, he or she first presses the reduction ratio selection key 12.

As a result, the magnification area display 11'a lights up, and the magnification can be set continuously in the range of 60% to 80%. Thereafter, while viewing the display on the magnification area display 11a, the variable volume 5 is operated to set the value to 70%, thereby completing the magnification setting operation.

Furthermore, at this point, if the operator wishes to make a copy with a reduction ratio of 80%, he or she presses the reduction ratio selection key 12 again. As a result, the magnification area display 11b lights up,
The reduction magnification can be set continuously in the range of 70% to 90%. Thereafter, while viewing the display on the magnification area display 11b, the variable volume 5 is operated to adjust to 80%, thereby completing the magnification setting operation. Further, at this point, if the operator wishes to make a copy with a reduction ratio of 90%, he presses the reduction ratio selection key 12 again. As a result, the magnification area display 11c lights up and the reduction magnification is 80.
The magnification can be set continuously in the range of % to 100%. Thereafter, while viewing the display on the magnification area display 11C, the variable volume 5 is operated to adjust to 90%, thereby completing the magnification setting operation. At this point, if the reduction magnification selection key 12 is pressed, the magnification mode is set to equal magnification.

FIG. 3 is a flowchart illustrating the control operation of the present invention. Note that (1) to (13) represent each step.

MC1 is the number of presses parameter N of the reduction magnification selection key 12
Set "0" to 1), wait for the reduction magnification selection key 12 to be pressed 2), and when the reduction magnification selection key 12 is pressed, increment the number of presses parameter N to "1" 3), Next, it is determined whether the number of presses parameter N is "4" (4). If this judgment is No, the lower limit value of the magnification setting area Y (50+ (NXIO))
(5). In the calculation of this step (5), N=
When it is 1, the lower limit value Y=60, the magnification area display 11a lights up according to this lower limit value (6), and sampling of the variable volume 5 is started (7). Next, it is determined whether the reduction magnification selection key 12 has been pressed (8), and if the reduction magnification selection key 12 has been pressed, the process returns to step (3), and steps (3) to (8) are repeated to set the magnification. Move the area to a higher class and press the reduction magnification selection key 12
If is not pressed, the sampling value Xl obtained in step (7) is sent to the analog input section of the MCI (8
), the obtained sampling value x1 is divided by 12.8 to obtain the converted value X (in this invention, the MCI is
At each time, the movement amount 256 of the variable volume 5 is divided into 20 and converted into actual measurement data. Therefore, divide the sampling value xl by 12.8, which is 256 divided by 20)
(10). Next, the conversion value obtained in steps (10) and (5) and the lower limit value Y are added to obtain the magnification value (60+
15.6=75.6) is determined and the control ends (11
).

On the other hand, if the determination in step (4) is YES, the same magnification mode is set (12), sampling of the variable volume 5 is prohibited, and the control ends (13). By repeating 8), the lower limit value Y
will move to 70.80.

That is, each magnification setting area overlaps and moves to a higher magnification area.

In the above embodiment, the case where the magnification setting area overlaps evenly has been explained, but the software is configured so that the magnification setting area can be set to full scale when the reduction magnification selection key 12 is pressed for the first time. This will further improve the magnification setting operation.
