Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a copying machine capable of forming a magnified / reduced copy image according to a set magnification.

(B) Conventional technology In a copying machine capable of forming a magnified / reduced image, usually a specified size such as B5 → A4 magnification (115%), A4 → B4 magnification (122%), etc. The magnification ratio or reduction ratio is stored as a fixed ratio, and the fixed ratio is sequentially called for each operation by operating the enlargement ratio call key or reduction ratio call key provided on the copier body. You can do it.
Further, a zoom key for finely adjusting the magnification by 1% is provided, and the magnification can be set by operating the zoom key. Then, copying is performed according to the set magnification.

A commonly used copying machine has a fixed mode (for example, magnification: 100%, number of sheets: one sheet, etc.), and the magnification, number of sheets, etc. are set when the predetermined time elapses without copying. It is set to a constant mode. Further, an equal magnification key for setting the equal magnification is individually provided, and the equal magnification is set by operating the equal magnification key.

(C) Problems to be Solved by the Invention However, conventionally, when copying at a fixed magnification, it was possible to easily set the magnification by operating the call key. However, copying is performed at an arbitrary magnification other than the fixed magnification. in case of,
It was very troublesome to call a fixed magnification close to that magnification and then gradually change to a magnification with the zoom key. In particular, if the user is more likely to copy with a fixed magnification than the number of times with a fixed magnification for reasons such as making a file with a fixed size, the magnification must be set with the zoom key for each copy at that arbitrary magnification. It was bothersome and a waste of time.

In a copying machine, the magnification is cleared after a certain period of time without the copying process. In the copying machine, even if the zoom key is operated to set an arbitrary magnification, the magnification is cleared while the user leaves the seat. Sometimes, I had to set the desired magnification again with the zoom key.

According to the present invention, a magnification other than the same magnification used last time or an arbitrary magnification input by a key is stored, and the magnification can be called preferentially, so that the magnification can be set easily and with few operations. The purpose is to provide a copier that can be used.

(D) Means for Solving the Problems The present invention comprises a magnification storage memory for storing a copy magnification and a magnification call key, and sequentially calls the magnification stored in the magnification storage memory each time the magnification call key is operated. In a copying machine that sets the specified magnification and performs copying according to the set magnification, the magnification storage memory is a first memory that stores a predetermined fixed magnification, and a previously used magnification or key input other than the equal magnification. And a second memory for storing the selected arbitrary magnification, and means for calling the stored contents of the second memory and the stored contents of the first memory in this order when the magnification call key is operated. To do.

(E) Function In the copying machine of the present invention, the previously used magnification other than the equal magnification can be stored in the second memory. In addition, an arbitrary magnification that is frequently used can be stored in the second memory. These magnifications are sequentially called every time a simple operation of the magnification call key is repeated, and copying is performed at the magnification. Further, the previous magnification or the arbitrary magnification stored in the second memory is called prior to the fixed magnification, and is called with a small number of operations. It should be noted that the setting of the equal magnification is usually set more easily than with the equal magnification key.

(F) Embodiment FIG. 3 is a plan view of an operation panel of a copying machine which is an embodiment of the present invention. The operation panel displays a mode setting key 1 for switching between a copy mode and a magnification storage mode, a copy key 2 for copying start and magnification storage, a ten key 3 for designating the number of copies and a storage magnification, and an input value from the ten key 3. Display unit 4, call keys 5 and 6 for calling the stored enlargement ratio and reduction ratio, zoom keys 7 and 8 for finely adjusting the enlargement ratio and reduction ratio, equal magnification key 9 for setting equal magnification, magnification A magnification display unit 10 for displaying is provided.

FIG. 3 is a block diagram of the control unit of this copying machine.

The entire control is performed by the CPU 11, and the CPU 11 is controlled by the mode setting key 1, copy key 2, numeric keypad 3,
The display unit 4, the magnification call keys 5 and 6, the magnification display unit 10, other input / output devices 15, and the copy process device 16 are connected. Each key and the operation program of the copy process device 16 are stored in the ROM 12 in advance. RAM 13 is used as a working area when the program is executed. RAM13 has a magnification storage memory M1, M2, a calling magnification area M3 for storing the magnification called from the magnification storage memory,
And a set magnification area M4 for storing the set magnification is provided.

FIG. 2 is a memory map of the magnification storage memories M1 and M2. The magnification storage memory is composed of a first memory M1 and a second memory M2. A predetermined non-rewritable fixed magnification is stored in the first memory M1. The second memory M2 is divided into two areas. M2-1 stores a magnification other than the same magnification used last time, and M2-2 stores an arbitrary magnification input from the numeric keypad 3. The first memory M1 and the storage area M2-2 for inputting an arbitrary magnification by key input are composed of an area for storing an enlargement magnification and an area for storing a reduction magnification.

The operation of the mode setting key 1 switches between the copy mode and the magnification storage mode. The copy key 2 and the numeric keypad 3 perform different functions in the copy mode and the magnification storage mode by the above-mentioned mode switching. That is, the ten-key pad 3 serves as a key for setting the number of copies in the copy mode and a key for designating an arbitrary magnification in the magnification storage mode. The copy key 2 is a key for starting the copy process in the copy mode and a key for storing the magnification specified by the ten key 3 in the magnification storage mode in the arbitrary magnification storage area M2-2 of the second memory M2.

The display unit 4 displays the number of sheets and the magnification input from the ten keys 3 and the error number when an error occurs.

The magnification display section 10 displays the copy magnification. The copier magnification is increased or decreased by 1%. Magnification call key 5,6
Is a key for calling the magnifications stored in the magnification storage memories M1 and M2, and the stored enlargement magnification and reduction magnification are sequentially called for each operation of the magnification call keys 5 and 6. The same size key 9 is a key for making the magnification equal, and the zoom keys 7, 8 are keys for increasing or decreasing the copying magnification by 1%.

When the magnification is called by the magnification call keys 5 and 6, the contents stored in the second memory M2 and the contents stored in the first memory M1 are cyclically called. That is, the previous magnification M2− of the second memory M2−
1, the arbitrary magnification M2-2, and the magnification of the first memory M1 are cyclically called. The magnification called by the operation of the magnification call keys 5 and 6, the magnification specified by the zoom keys 7 and 8 and the magnification that is reset when a certain period of time has passed without copying are temporarily stored in the call magnification area M3 and copied. When the copy key 2 indicating the start is operated, it is stored in the set magnification area M4. Set magnification area when copying
Copying is performed according to the magnification stored in M4.

FIG. 1 is a flow chart showing the operation of the copying machine described above.

First, warming up is performed in step n1 (hereinafter, "step ni" is simply referred to as "ni"). When the warming up is completed, the process proceeds to n2 and it is determined whether or not the mode setting key 1 has been operated. When the mode setting key 1 is operated, the magnification storage mode is set, and the magnification is stored in the storage area M2-2 of the arbitrary magnification of the second memory M2. When n3 is used to input an arbitrary magnification with the numeric keypad 3 and n4 is used to operate the copy key 2, the magnification designated with the numeric keypad 3 is stored in the arbitrary magnification storage area M2-2 of the second memory M2 in n5. It When the magnification is stored, it is determined whether the magnification designated by the ten key 3 is the enlargement magnification or the reduction magnification, and the magnification is stored in each area. Further, the mode is switched to the copy mode at the same time when the magnification is stored. Steps n2 to n5 are repeated to store a plurality of arbitrary magnifications in the magnification storage memory.

When the mode setting key 1 is not operated at n2, the copy mode is set, the ten key 3 sets the number of copies, and the copy key 2 starts the copy process. When the enlargement magnification call key 5 or the reduction magnification call key 6 is operated in n6, the operation proceeds to n7 to call up the magnifications stored in the magnification storage memories M1 and M2 and store them in the calling magnification area M3.
When the steps of n6 → n7 are repeated, the call magnification area M3 is replaced with the next one each time. In this way, the magnifications stored in the magnification storage memories M1 and M2 are sequentially called. Magnification is called by the previous magnification M2-1, arbitrary magnification M2-2, and fixed magnification as described above.
The operation is repeated in the order of M1 for each operation of the call keys 5 or 6. For this reason, the previously used magnification and any key-input magnification are preferentially called.

Further, the number of copies and the like are set in steps not shown.

At n8, it is determined whether or not the copy key 2 is operated. When the copy key 2 is operated, it is first determined in n9 whether or not the magnification of the set magnification area M4 is the same size. If it is not the same size, the content of the set magnification memory M4 is changed to the previous magnification storage area M2- 1
After saving to, the contents of the call magnification area M3 are moved to the set magnification memory M4. As a result, the previously used magnification is stored in the magnification storage memory M2-1 and saved,
The magnification to be copied is stored in the set magnification area M4, and it is possible to copy at that magnification.

When the previous magnification is stored and the current magnification is set
Proceeding to n11, the copy process is performed with the magnification stored in the set magnification area M4.

(G) Effect of the Invention In the copying machine of the present invention, since the arbitrary magnification which has not been stored in advance or the magnification used last time is stored in the second memory, the magnification stored in these magnification storage memories at the time of copying. You only have to operate the call key to call,
Easy to operate. In addition, since the magnification used last time or the arbitrary magnification input by the key is called with priority over the fixed magnification, the number of operations when calling those magnifications can be reduced.
