Abstract

PURPOSE:To display the movement of a set value especially at the time of a stepless variable magnification request so that the magnification can be optionally changed by selecting plural fixed magnification setting means setting up previously fixed copying magnification and optional magnification setting means setting up an optional copying power. CONSTITUTION:When the operator depresses an equal magnification copying mode key 209, a fixed copying magnification mode display device 212 is turned on and the copying of equal magnification is selected. When the equal magnification copying mode key 209 is turned off and a variable magnification copying mode selection key 210 is depressed, a fixed copying magnification mode display device 215 showing 67% contraction is turned on and contraction copying having 67% power modification is selected. In addition, stepless copying magnification mode display device 216 is turned on by depressing the key 210 and stepless variable magnification is selected. In this case, an optional copying magnification can be set up by a stepless variable magnification lever 217. When the magnification value is changed by the stepless variable magnification lever 217 in said mode, the magnification value after modification is displayed on a display device 205 at the detection of the modification.

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an image processing apparatus that displays a copy magnification when selecting a copy magnification.

[Prior art and its problems]

2. Description of the Related Art There have been many copying machines capable of displaying copying magnification values. In recent years, the number of machines that can change the magnification value continuously has been increasing. However, when the magnification value changes continuously, the means for notifying the operator of the magnification value must also change its display continuously. There is a method to provide a dedicated display that constantly displays this magnification value, but it is complicated because it has to be distinguished from other displays, it is expensive, and it does not need to be displayed all the time, but it is displayed all the time. There were problems such as.

6υ starts while the is lit, the magnification (stepless polyurethane voltage) is set by the variable resistor, this set value is converted to the magnification input data, and the process returns to the main routine.

The flow shown in FIG. 6(b) starts with the stepless copy magnification mode display 2-16 lit by operating the variable magnification copy mode selection key 210, and first, the magnification mode is set to the stepless copy magnification mode. Determine if there is, and then YES
If so, determine whether the set magnification has changed during the copy operation by comparing the current magnification with the set magnification before the copy operation.) If there is a change in the magnification, set a 2 sec timer and if there is no change. Returns to the main routine after 2 seconds @4゜If step @4 returns 2 seconds
Before ec has elapsed, the magnification display data at the time of copy completion is sent to the display 205 and the process returns to the main routine.
