Abstract

PURPOSE:To improve operability by providing a selection means which witches what variable power mode is set by reducing and enlarging keys used in common in respective variable power modes. CONSTITUTION:In the case of performing zooming variable power, a mode switching key 103 is depressed once from an initial state, so that a mode is switched to a zoom variable power mode and an LED 104 is turned off and an LED 105 is turned on. Then, the reducing key 101 and the enlarging key 102 are properly operated to set optional magnification. By depressing the key 103 further from the state of the zoom variable power mode, the set state of the magnification in the vertical direction of a vertical and horizontal independent zoom variable power mode is obtained, and an LED 105 is turned off and an LED 106 is turned on. Then, the magnification in the vertical direction is optionally set by the keys 101 and 102. Furthermore, by depressing the key 103 from such a state, the set state of the horizontal magnification of the vertical and horizontal independent zoom variable power mode is obtained, and an LED 106 is turned off and an LED 107 is turned on, then the magnification in the horizontal direction is set in the same manner.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image forming apparatus having a variable magnification function.

[0002]

2. Description of the Related Art Generally, a conventional copying machine is capable of designating a magnification for copying. As a method of scaling, for example, zoom scaling that can be arbitrarily set in 1% increments, standard scaling that is selected from several preset magnifications, and the original size is specified by specifying the paper size. There were automatic scaling that calculates the magnification from the paper size and automatically set it, or vertical and horizontal independent zoom scaling that allows you to set the vertical and horizontal magnification independently.

[0003]

However, in the above-mentioned conventional example, when there is a fixed variable magnification, zoom, and vertical and horizontal independent zoom, keys for setting the vertical and horizontal magnifications are required. Therefore, the total number of keys is increased, the configuration of the operation unit is complicated, and the arrangement space is increased. Further, in the fixed form, zoom, and vertical / horizontal independent zoom, the same action of setting the magnification is performed, but it is necessary to operate different keys for each, and there is a problem that the operation becomes complicated.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an image forming apparatus capable of easily operating various scalings with a small number of keys.

[0005]

According to the present invention, when setting, for example, a fixed size variable magnification, a zoom variable magnification, a vertical and horizontal independent zoom variable magnification, etc., two keys of enlargement and reduction, and the roles of those two keys are played. Standard enlargement / reduction, zoom enlargement / reduction, vertical and horizontal independent enlargement / reduction of independent zoom 4
By providing selection means for selecting from one of the two functions, it is possible to prevent an increase in the number of keys, simplify the configuration, and improve operability.

1 is a plan view showing a part of an operating portion of an image forming apparatus according to a first embodiment of the present invention.

The operation unit of this embodiment has a reduction key 101 for instructing reduction of an image, an enlargement key 102, a switching key 103 for changing the magnification change mode, and a light in the standard magnification change mode. An LED 104 that is turned on, an LED 105 that is turned on in the zoom variable magnification mode, and an LED 106 that is turned on when the vertical and horizontal independent zoom variable modes are set vertically.
LE that lights up when the horizontal and vertical independent zoom scaling modes are set
It has a D107 and a display device 108 for displaying the setting contents.

2 and 3 are plan views showing the display screens 201 to 210 of the display device 108.

First, in the initial state, the standard variable magnification mode is set, the LED 104 is turned on, and the display device 10 is turned on.
A screen 201 is displayed at 8. When the reduction key 101 is pressed here, the magnification is set to 86%, and the display device 1
A screen 202 is displayed on 08. Further, when the reduction key 101 is pressed, the screens are sequentially switched to 81% and 70%, and the display device 108 also sequentially displays the screen 203 and the screen 204.

Similarly, when the enlargement key 102 is pressed, the magnification is switched to 115%, 122% and 141%, and the display device 108 also displays the screen 205, the screen 206 and the screen 2.
It switches to 07.

Next, when it is desired to set the zoom magnification, if the switch key 103 is pressed once from the initial state, the mode is switched to the zoom magnification mode, the LED 104 is turned off and the LED 105 is turned on. Here, the reduction key 101 and the enlargement key 102 are appropriately operated to set an arbitrary magnification.
The set magnification is displayed on the display device 108 as a screen 208.

When the switching key 103 is further pressed in the zoom variable magnification mode, the vertical / horizontal independent zoom variable magnification mode is set, and the LED 105 is turned off and the LED 106 is turned on. Further, a screen 209 is displayed on the display device 108. Here, the reduction key 101 and the enlargement key 102 are used to arbitrarily set the vertical magnification.

Further, from that state, the switching key 103
When is pressed, the horizontal and vertical independent zoom magnification / reduction mode is set, the LED 106 is turned off and the LED 107 is turned on, and the screen 210 is displayed on the display device 108.
The magnification in the horizontal direction is set here as well.

As described above, the reduction key 101, the enlargement key 102, and the switching key 103 can be used to easily set the scaling ratio of each mode.

Next, a second embodiment of the present invention will be described. The difference from the first embodiment is that, as shown in FIG. 4, the LED for displaying the mode is eliminated, and instead of the screens 401 to 403 shown in FIG. 5, the current mode is displayed in the screen. To be done. The other points are the same as those in the first embodiment.

Next, a third embodiment of the present invention will be described. In the third embodiment, as shown in FIGS. 6 to 9, a display device 500 having a touch sensor on the entire surface is provided, and the reduction key 501 and the enlargement key 50 are used as the touch sensor.
2, a variable magnification mode switching key 503 and a setting content display area 504 are provided. That is, each key 5
Although 01, 502, and 503 are pictures displayed on the display device 500, they function as keys because the entire surface of the display device 500 is a touch sensor.

In the state shown in FIG. 6, the standard variable magnification mode is set. When the switch key 503 is pressed here, the zoom magnification / reduction mode is set and the screen is switched as shown in FIG. further,
When the switching key 503 is pressed, the screen switches to that shown in FIGS. 8 and 9 and the vertical and horizontal independent zoom settings are made.

In this embodiment, since the reduction key and the enlargement key are soft keys displayed on the screen, it is possible to give a name suitable for the function to each mode.

Next, a fourth embodiment of the present invention will be described. The fourth embodiment differs from the third embodiment only in the vertical / horizontal independent zoom setting method. That is, in the fourth embodiment,
The vertical / horizontal independent zoom is set only on the screen shown in FIG. Only at this time, the four keys 901 to 904 are displayed, and the keys 901 and 902 are used for the vertical magnification and the keys 903 and 90.
Use 4 to set the horizontal magnification. In this embodiment, the vertical / horizontal independent zoom can be set without pressing the switching key.

[0020]

As described above, according to the present invention,
Reduction and enlargement keys that are commonly used for each scaling mode,
By having a selecting means for switching which scaling mode is to be set by the reduction and enlargement keys, the number of keys of the operation unit can be reduced, the configuration can be simplified, and the operability can be improved. There is an effect that can be.
