PURPOSE:To change magnification setting contents according to a zooming keys depressing method and to improve operability by performing a control in the way that a magnification is changed into a minimum magnification when a zooming-up key is depressed when a maximum magnification is set and changed into the maximum magnification when a zooming-down key is depressed when the minimum magnification is set. CONSTITUTION:When the zooming-up key is depressed once, the magnification is set up by one percent on an enlargement side and when the zooming-down key is depressed once, the magnification is set down by one percent on a reduction side. Besides, when the zooming-up key is depressed when the maximum magnification is set, the magnification is changed into the minimum magnification. When the zooming-down key is depressed when the minimum magnification is set, the magnification is changed into the maximum magnification. Thus, in a controlling mode in which a zooming variable power key is depressed every time an operation is performed, the maximum magnification is immediately changed into the minimum magnification and the minimum magnification is immediately changed into the maximum magnification. Thus the operability can be improved. |
