Abstract

PURPOSE:To improve operability for setting up a variable power rate by forming a means for calculating the number of times of copying necessary for a repeating cycle and a variable power rate in each copying when it exceeds the maximum magnification and a setting means for setting up each variable power rate setting up means an optical system. CONSTITUTION:A reading means reads out the original size specified by an input means and the specified copying size and variable power rate calculating means calculates a variable power rate determined by the original size and the copying size at the reception of an input from the reading means. If the calculated variable power rate is less than the maximum magnification, the optical system is set up to the calculated variable power rate. If the value exceeds the maximum value, a variable power step calculating means calculates the number of times of copying necessary for a repeating cycle regarding the copied transfer paper as its new original and a variable power rate of each copying to reach the current value to the calculated one. Then, the optical system is set up to the variable power rate of each copying time in the repeating cycle operation based upon the result of the variable power rate step calculating means by the each variable power rate setting means. Thus, the operability of the setting of the variable power rate can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a copying apparatus having a zoom magnification function.

(Prior art) Recently, in the case of a hidden camera with a variable magnification function, fine-grained ", r ht: ', step example is 0.5 to 1.41.
I'm thinking of incorporating a zoom magnification function that can change the variable range of 0.01 or 0.01 or oot.

With a conventional zoom device that has a zoom magnification function, the magnification ratio determined by the original size and copy size, or within the maximum magnification of 66 small or enlargement set on the photocopier (the magnification ratio KN However, with this method, it is not possible to obtain the desired magnification. This is inconvenient because it becomes ugly.

Therefore, when making copies with a variable magnification ratio that is not variable, the copied transfer paper is used as a new document and this process is repeated several times to make copies of the required size.

However, in this case, in the conventional example, the variable magnification must be set for each trough of copying, which has the drawback of extremely poor operability.

(Purpose) The present invention has been made in consideration of the drawbacks of the conventional example, and it provides a variable range of magnification or zoom magnification that can be automatically opened by specifying the original size and copy size. If the copy size exceeds 5, the number of times of copying to reach the copy size and the number of times of copying for each copy are set. The purpose is 1''.

(Senari) From now on, the construction of this uraaki will be explained based on the illustrated embodiment.

Figure 1 shows a schematic diagram of the real-FXI of 1・ψ operation r%], and the zoom finger is used in combination with the zoom enlargement key 3 or the zoom/reduction key 4, and the zoom finger is used in combination with the zoom key 3 or the zoom/reduction key 4. When the zoom magnification ratio is designated numerically using the numeric keypad 5, the magnification ratio for enlargement or reduction is displayed electronically on the display section 6.Then, prior to operating the numeric keypad 5, the document size designation key 7 is operated. If the copy size specification key 8 is pressed, the copy size is accepted and displayed.
The original) 11"4 size at this time and the variable magnification 4/I based on each copy size specification are displayed. Also, when the zoom specification key 2 is not operated,

When standard reduction etc. is specified, these specified values are displayed on the display section 6.

If the maximum magnification is exceeded, the magnification step O/L intelligence means 24 determines how many times the specified reduction or enlargement must be repeated until the specified magnification is reached. I'm sorry for that. This result is output to the counter 25.

This is done by copying the 1st original in 1 color and 1 color, then copying this copied 6th paper as a new 1st manuscript, and then using this 1st manuscript as the next manuscript. This is a cyclical operation.

Furthermore, at this time, the magnification of each time during the same cycle is set by each time magnification setting means 26, and this is displayed on the display section 6.

When the phase change by each key on the operation section 1 is input, it is determined whether or not the original or copy size designation key 7.8 has been operated.
If not, the optical system 23 is set using the standard setting key group 9. When the original t= and copy size designation keys 7 and 8 are operated, the numeric keypad 5 is switched to several percent + input 1. When the original size a and the copy size b are specified, the magnification ratio X=b7a is calculated '1'. At this time, the numeric keypad 5 is returned to 1 for specifying the number of copies. If X is within the maximum magnification, the optical system is set to X, but if it exceeds the maximum magnification, the required number of copies n is reduced to mH, and this number n is reduced by Kl for each copy. Komari n indicates the remaining number of times copying should be performed. Magnification rate An for each number n
is calculated each time the copy is made, and the optical system 23 is set to be stiff and displayed.
