Abstract

PURPOSE:To prevent the generation of a copying miss by returning forcedly copying magnification or display to a specific magnification when prescribed operation is applied to a copying machine after copying in an automatic magnification selecting mode. CONSTITUTION:If any one key is depressed under the state that the 1st magnification setting mode switching key groups 85-88 are operated, a numeral inputted by ten keys 0-9 and displayed on a display device 52 is stored in memories corresponding to the keys as the magnification of copying. Since the magnification of copying is previously set up in the memory corresponding to the key, the 2nd magnification setting key groups 90-93 are considered so that the copying operation can be executed on the basis of the preset value without setting up the value like the 1st key groups. If the copying operation in another mode is to be executed after completing the copying by the automatic magnification selecting mode, a specific copying magnification and its display are selected immediately and forcedly, so that inconvenience starting the copying operation under unknown magnification is removed.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention provides a method for determining the small copy magnification and key ζ from the detected original paper height size and copy paper noise. 'L
This calculated magnification is used to control the copying machine (191) having an automatic magnification selection mode that allows the user to change the initial image 41'1 according to the calculated magnification.

Conventional technology automatic copying machine with 'fi jll' selection mode is
It is possible to set the magnification steplessly within the predetermined tolerance ranges 1iii and 4, and in order to facilitate the selection of the frequently used 1-field furnace magnification, the predetermined copying magnification is recorded. (, ii・l: J', write in the column f, let i3-C, double the cow (key for selection 4': t'r work q1 to call up the stand\rate and copy it. The system is configured such that the ability to perform the action is 100 i fil:.Then, the memorized copying magnification is selected (displayed in correspondence with <vj work, It is designed so that the user can tell whether f(j) is being taken at such a magnification.

On the other hand, in the automatic magnification selection mode, such as J, the magnification is set by calculating i'iu from the size of the original 41;:] and the size of the copy paper, regardless of the stored predetermined magnification. Since two copies are automatically made, there is no need to display the magnification selection (for U' river use, it is necessary to be aware of the Neri copy magnification determined by calculation)! Since there is no "j", there is currently no display regarding magnification.

However, if copying becomes really frustrating in automatic magnification selection mode,
Even after the discarding operation is completed, the optical system, drive control mechanism, etc. retain the control data based on the selected magnification at that time, and the data is not controlled by the user. Since the next user is not informed of this, the next user may simply start the copying operation, resulting in an inconvenient copying error. Copying machines are usually equipped with an auto-reset function that resets each glaze setter to the standard state if it remains inactive or unoperated for a certain period of 11+1F, but the auto-reset function is Garu1)
1 often causes such inconvenience.

Purpose The present invention has been made with attention to the above point, and after copying in the automatic magnification selection mode, the copying ratio is 4', Y': the copy is made. It is an object of the present invention to provide a control device which prevents the occurrence of copy mistakes as described above by forcibly returning the copy magnification or display to a specific magnification when the copying occurs.

Example Embodiments of the present invention will be described below with reference to the drawings.

Due to the relationship between double paper feeding and the sashimi method, even if the paper to be fed already protrudes almost to the side of the sashimi at the start of feeding, the trailing edge of the paper may be 1 ( The time is set in accordance with the paper size so that the paper feed roller does not rotate after passing through the roller section.

This control allows the paper to be fed without interfering with the paper feeding operation.
Accidents such as double sheet feeding can be reliably prevented.

Note that to select the paper feed unit, specify the size of the paper feeder and select the paper feeder in which it is attached.

Either method for specifying the paper feed section using jlli' as the primary designation method is not suitable.

In step 09), it is determined that the control timer has ended, and in step (#1710), the introduction paper change that was revealed in FIG. 25 above is set to 11''.

Control timers (T-G) to (T-K) are used to control the timing roller (21) when the timing roller (21) is turned on and the copy paper is sent out, and after the copy paper is 'i7. i finishes passing through the timing roller (21), the timing roller stops again, and then the leading edge of the next sheet passes through the timing roller (21).
1) This is to define the next lj 'ri' and the timing to start feeding the paper according to the size of the river ♀1t (length in the conveying direction) so that the paper reaches the sheet. On the other hand, the control timers (T-G/) to (T-ni/) set when copying on thick paper have their set times determined according to the size of the copy paper, just like when copying on plain paper. In addition, consider the reduction in temperature of the fixing device (23) due to the use of cardboard and the time required to rise from there to the fixing temperature, and determine the shortest time width in that case. is determined through a process. Specifically, the curvature of the 2t tracing paper is 1, and the length of the paper that is sent out rapidly is 1/1/2.
