Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a copying machine in which information relating to copying conditions such as a size of a recording medium, a copy magnification and the number of copies can be arbitrarily selected and set.

[0002]

2. Description of the Related Art Generally, a copying machine irradiates a surface of a document placed on a document reading section with light from a light source, and reflects the reflected light through an optical system on a charged photosensitive drum which is rotationally driven. An image is formed on the surface of the drum by exposure, the image is developed with toner, then transferred to a recording medium, and then heat-fixed for copying.

In such a copying machine, the user can arbitrarily select and set information relating to the copying conditions such as the size of the recording medium, the copy magnification and the number of copies by key operation.

[0004]

However, in the conventional copying machine of this type, only one type of copying condition can be set in one copying operation.

Therefore, when it becomes necessary to copy the same original document under different conditions, conventionally, if a desired recording medium size, copy magnification, the number of copies, etc. are initially set, the start key is operated. If the recording medium size, the copy magnification, the number of copies, etc. were reset after the first copy, the start key had to be operated again to perform the second copy. Therefore, the user has to wait on the side of the copying machine until at least the first copying is completed, which is inefficient.

Therefore, the present invention is to provide a copying machine capable of continuously copying the same original document under different copying conditions by one start operation and improving the processing efficiency.

[0007]

SUMMARY OF THE INVENTION According to the present invention, there is provided a copy mechanism section for optically detecting an image on a document surface and copying it on a recording medium, and a storage having an area capable of storing information on copy conditions for a plurality of records. Section, an input section for selectively inputting information about copying conditions, an information setting means for sequentially setting the input information in the storage section every time information about copying conditions is input through the input section, A start instructing means for instructing start, a setting information reading means for sequentially reading out information relating to the copying conditions set in the storage section when the instructing of the copying is instructed by the instructing means, and the reading means for transmitting information concerning the copying conditions. And a copy control unit that controls the copy mechanism unit to copy each time it is read.

[0008]

According to the present invention having such a structure, when the information regarding the copying conditions such as the size of the recording medium, the copying magnification, the number of copies, etc. is first inputted through the input section, the input information is the first information of the storage section. Set in the area. Subsequently, when the information regarding the copy condition different from the above is input again through the input unit, the input information is set in the second area of the storage unit. Subsequently, when the start instructing means gives an instruction to start copying, first, the information on the copying condition set in the first area of the storage section is read out, and the operation of the copying mechanism section is controlled based on the information on the copying condition. Then, the image on the document surface is copied onto the recording medium. Then, the information about the copy condition set in the second area of the storage unit is read out, the operation of the copy mechanism unit is controlled based on the information about the copy condition, and the image of the same original surface is copied onto the recording medium.

Is formed.

A table counter 42 for counting the area number X of the setting table 41, a flag area 43 in which a paper size flag f1, a copy magnification flag f2, a copy number flag f3 and a # key input flag f4 are set, respectively. , A default value area 44 in which the default values D1, D2 and D3 of the paper size, the copy magnification and the number of copies are preset, and a temporary storage for temporarily storing the registered values M1, M2 and M3 of the paper size, the copy magnification and the number of copies. The buffer 45 and the like are formed in the RAM 14.

Therefore, the CPU 11 is particularly shown in FIG.
The program is controlled so as to execute various key processes shown in FIG.

First, the paper size key 3 on the operation panel 25
When 1 is keyed in, the paper size flag f1 is set (1) in the flag area 43 as shown in FIG. 4A, and the paper size data corresponding to the input key is set as the paper size registration value M1. After storing in the temporary buffer 45, this key processing is completed.

Further, the enlargement / reduction key 3 on the operation panel 25
When 3 is keyed in, the copy magnification flag f1 is set in the flag area 43 as shown in FIG. 4B (1).
At the same time, the initial value of the magnification data S is set to “100”. Next, when the enlargement key 33a is keyed in, "+1" is added to the magnification data S, and when the reduction key 33b is keyed in, the magnification data S is subtracted from "-1". After that, when the enlargement key 33a is pressed, the magnification data S is incremented by "+1", and when the reduction key 33b is keyed in, the magnification data S is subtracted by "-1". When any key other than the enlargement / reduction key 33 is pressed, the magnification data S is changed to the copy magnification registration value M2.
Is stored in the temporary buffer 45, and this key processing ends.

Further, when numerical data is input by the key input of the number key 34 of the operation panel 25, FIG.
As shown in (c), the copy number flag f3 is set (1) in the flag area 43, the numerical data is stored in the temporary buffer 45 as the copy number registration value M3, and this key processing is ended.

When the # key 36 of the operation panel 25 is pressed, the # key input flag f4 is set (1) and the count value x of the table counter 42 is set as shown in FIG. 5A. Is updated by "+1".

Next, the flag area 43 is examined. When the paper size flag f1 is not set (1), the paper size default value D1 in the default value area 44 is stored in the temporary buffer 45 as the paper size registration value M1. When the copy magnification flag f2 is not set (1), the copy magnification default value D2 in the default value area 44 is stored in the temporary buffer 45 as the copy magnification registered value M2. Also, the copy number flag f
If 3 is not set (1), the copy number default value D3 in the default value area 44 is stored in the temporary buffer 45 as the copy number registration value M3.

Next, the registered values M1 to M3 stored in the temporary buffer 45 are transferred to the area of the setting table 41 corresponding to the count value x. After that, the paper size flag f1, the copy magnification flag f2, and the copy number flag f3 are reset (0), and the key processing ends.

When the clear key 35 of the operation panel 25 is pressed, the setting table 41 and the temporary buffer 45 are cleared as shown in FIG. 4 (b). Next, the flags f1 to f in the flag area 43
4 is reset (0), the count value x of the table counter 42 is reset to "0", and this key processing is completed.

The start key 37 of the operation panel 25
When is input by key, the flag area 43 is checked as shown in FIG. If the # key input flag f4 is set (1), the flag f4 is reset (0) and the count value x of the table counter 42 is reset to "0".

Next, after updating the count value x of the table counter 42 by "+1", it is judged whether or not data (sheet size, copy magnification and number of copies) is stored in the x-th area of the setting table 41. To do. If the data is stored, the data is read and the copying mechanism unit is controlled based on the read data to perform the copying operation.

Thereafter, the count value x is further increased by "+".
1 ”and then it is determined whether or not data is stored in the x-th area of the setting table 41. If the data is stored, the data is read in the same manner as described above, and the copying mechanism unit is controlled based on the read data to perform the copying operation.

In this way, if all the data stored in the setting table 41 are sequentially read and the copying operation is continuously performed based on the read data, this processing ends.

Here, in the start key processing of the CPU 11, when the start instructing means (start key 37) is instructed to start the copying, the information regarding the copying conditions set in the storage section (setting table 41) is sequentially read out. An information reading unit and a copy control unit that controls the copying mechanism unit based on the read information to copy each time the information about the copying condition is read by the reading unit.

When the # key input flag f4 is not set (0) in the flag area 43, the default values D1 to D1 stored in the default value area 44 are stored.
When the copying mechanism section is controlled based on D3 to perform the copying operation, the key processing is ended.

In this embodiment having such a configuration, for example, [A4] data is set as the paper size default value D1 in the default value area 44, and "100"% is set as the copy magnification default value D2. Therefore, “1” is set as the default number of copies D3.

Here, for example, the user makes 50 copies of the [B5] size original document on the [B5] size paper at the same size, and enlarges the same original document on the [A4] size paper by 115% to 30 sheets. When it becomes necessary to make a copy, the user first inputs the clear key 35 to clear the setting table 41 and the temporary buffer 45.

Next, the user operates the paper size key 31 to select the paper size [B5], and also the number key 34 to key in the number of copies [50]. Then, the # key 36 is pressed. Then, in the first area of the setting table 41, the paper size [B
5], copy magnification [100] (default value D2), and number of copies [50].

Next, the user operates the enlargement key 33a to set the copy magnification [115]%, and at the same time, the number key 34 is keyed in to input the number of copies [30]. Then, the # key 36 is pressed. Then, in the second area of the setting table 41, the paper size [A
4] (default value D1), copy magnification [115], and number of copies [30].

Next, the user inputs the start key 37 to instruct the start of copying. Then, first, information about the copy condition stored in the first area of the setting table 41 (paper size [B5], copy magnification [10
0], the number of copies [50]) is read, and the copying mechanism is controlled based on the information to perform copying. As a result, the image of the surface of the [B5] size document placed on the document reading unit is copied to 50 [B5] size sheets at the same size.

Subsequently, the information regarding the copy conditions (paper size [A5], copy magnification [115], number of copies [30]) stored in the second area of the setting table 41 is read out, and based on that information. The copying mechanism section is controlled to perform copying. As a result, the image of the same document surface as the above is enlarged and copied on 30 sheets of [A4] size paper.

As described above, according to this embodiment, when the start key 37 is operated with a plurality of copying conditions such as paper size, copying magnification, and number of copies set, the same original placed on the original reading portion is read. Since the image of the surface is successively copied under each copying condition, one start key 3
With seven operations, it is possible to continuously copy the same document under different copy conditions. Therefore, when it is necessary to copy the same original document under different conditions, it is possible to perform the copy under each condition by one operation of the start key, so that it is complicated to reset the condition each time one copy is completed. It is possible to improve the processing efficiency.

For example, in the case of the above example, conventionally, after copying 50 sheets under the first copying condition, it is necessary to reset the copying condition. Therefore, the user must wait until the first copying is completed. However, in this embodiment, 2
If the start key 37 is keyed after setting the number of times, another task can be performed until the copying of a total of 80 sheets is completed, which is efficient.

Although the size of the recording medium, the copy magnification, and the number of copies are shown as the information relating to the copying conditions in the above embodiment, the present invention is not limited to this. For example, the copying density set by the density key 32 is combined. It is also possible. Of course, various modifications can be made without departing from the scope of the present invention.

[0042]

As described in detail above, according to the present invention, every time information relating to a copying condition is input through the input section, the input information is sequentially set in the storage section, and the start of copying is instructed. And the information relating to the copying conditions set in the storage section are sequentially read out, and the copying mechanism section is controlled based on the read-out information to perform copying. Therefore, it is possible to provide a copying machine capable of continuously copying under different copying conditions and improving the processing efficiency.
