Next, a block diagram of the electric system of the first embodiment configured as described above will be described with reference to FIG. In the first embodiment, as shown in FIG. 2, a CPU (Central Processing Unit) 201, a ROM (Read
(Only memory) 202 and RAM (random access memory) 203. CPU 201 is RO
The resources are controlled by a program written in advance in M202. This control includes various calculations and determinations in the flowcharts shown in FIGS. 3 and 4, and details thereof will be described later. The RAM 203 temporarily stores various data when the CPU 201 controls each unit.

The CPU 201 has an I / O port 2
04, the memory 102 and the operation unit 103 are connected, and the I / O port 205 connects the scanner 101 and the plotter 105. The CPU 201 controls the memory 102, the operation unit 103, the scanner 101, and the plotter 105. Are respectively controlled. Each setting switch is input to or output from the operation unit 103, each motor signal, each paper signal or paper type signal is input to the plotter 105, and a document width signal or the like is input to the scanner 101.

Next, an example of the control operation of the first embodiment configured as described above will be described with reference to the flowcharts of FIGS. In this description, a case where the user sets the trial copy mode by operating the operation unit 103 will be described. Here, the test copy mode is a mode in which a test copy (sample copy) of an original is performed on only one sheet of recording paper prior to an original copy.

Here, the test copy mode is set by the user operating the operation unit 103, and if it is determined that the test copy mode is set (step 1; Y), the document width sensor of the scanner 101 and the document The width and length of the original are detected by the length sensor, and the detected original width and original length are determined by RA.
After storing the original in M203, the scanner 101 reads the original, and stores the read image data of the original in the memory 102.
(Step 2). Next, it is determined whether or not the paper quality priority mode has been set by the user (step 3). If the determination is negative (step 3;
N), it is determined whether or not the manual magnification mode is set (step 4). Here, the paper quality priority mode is a mode in which, when the user gives an instruction to give priority to the paper quality from the operation unit 103, a process according to the instruction is performed.
In addition, the manual scaling mode is a mode in which, when the user has arbitrarily set a scaling ratio from the operation unit 103, processing according to the scaling ratio is performed.

Next, when the manual magnification mode is not set (step 4; N), it is determined whether or not there is an instruction to cancel the magnification (step 5). (Step 5; N) It is determined whether or not the paper width designation scaling mode is set (Step 6).
Here, in the paper width designation scaling mode, when the paper width of the roll paper is selected by the user, copying is performed on the selected roll paper. If the result of determination in step 6 is that the paper width designation scaling mode is not set (step 6; N), the minimum width of the plurality of roll papers set in the paper feed unit and the original width sensor are read. The minimum reduction ratio is calculated from the original width (step 7). That is, in step 7, each width of the set roll paper is compared with the width of the original read by the original width sensor, and the width of the set roll paper is smaller than the width of the original to be transferred. The minimum reduction ratio (magnification) is determined from the width of the narrowest roll paper and the width of the original.

Next, the document length detected by the document length sensor is
The document length is converted into a document length corresponding to the obtained reduction ratio, and the converted document length is set as a length (cut length) when the roll paper having the minimum width is cut by the paper cutting unit 112 (step 8). Next, the roll paper having the minimum width is supplied to the plurality of paper feeding units 108 and 110.
(Step 9). The plotter 105 stores the selected roll paper in the memory 10 at the obtained reduction ratio.
2 is copied. The roll paper is cut by the paper cutting unit 112 at the determined cutting length during copying or the like, and is discharged from the discharge port after the copying is completed (step 10). By such processing, the whole image can be reduced and the whole image can be copied onto roll paper, so that the roll paper can be saved and the layout of the entire image when using the two-point instruction erasure or the composite edit mode can be checked. Easy trial copy (sample copy) can be realized.

When the manual magnification mode is set in step 4 (step 4; Y),
The user sets the reduction ratio set and input from the operation unit 103 (step 11). In this case, the roll paper having the minimum width is determined based on the document width detected by the document width sensor and the set reduction ratio, and based on the document length detected by the document length sensor and the set reduction ratio. Then, the determined cutting length of the roll paper is obtained (step 8). Next, the roll paper having the determined minimum width is selected (step 9). The plotter 105 copies the image of the document stored in the memory 102 at the reduction rate set on the selected roll paper. The roll paper is cut by the paper cutting unit 112 at the obtained cutting length, and is discharged from the discharge port (step 10).

According to such processing, the user can arbitrarily set the reduction ratio and output the image, so that the image quality can be easily checked. Therefore, as described above, when the reduction ratio is automatically set, for example, when the document width is “A0”, the set roll paper is “A4” and the width is 210 mm,
The reduction ratio is 25%, which causes a problem that a fine image cannot be confirmed. However, such a problem can be prevented.

When it is determined in step S5 that there is an instruction to cancel the magnification (step 5;
Y), the reduction ratio is set to “100%” (step 12).
In this case, the roll paper having the minimum width is determined based on the original width detected by the original width sensor and the reduction ratio “100%”, and the original length and the reduction ratio “1” detected by the original length sensor are determined.
00% ", the determined cut length of the roll paper is obtained. Next, the roll paper having the determined minimum width is selected (step 9). The plotter 105 copies the image of the document stored in the memory 102 at the reduction rate of “100%” on the selected roll paper. The roll paper is cut by the paper cutting unit 112 at the obtained cutting length, and is discharged from the discharge port (step 10). According to such processing, when there is no need for scaling (reduction), the user can cancel the scaling function, so that the image can be easily checked.

In step 6, when the paper width designation scaling mode is set (step 6;
Y), proceed to step 13; In step 13, the minimum reduction ratio is obtained from the width of the selected roll paper and the width of the document detected by the document width sensor. Next, the original length detected by the original length sensor is converted into an original length corresponding to the obtained minimum reduction ratio, and the converted original length is cut by the paper cutting unit 112 on the selected roll paper. (Step 14). Next, the plotter 105 copies the image of the document stored in the memory 102 at the determined reduction ratio on the selected roll paper, and the roll paper is cut by the paper cutting unit 112 at the determined cutting length. Then, the paper is discharged from the paper discharge port (step 10). By such processing, the width of the roll paper can be set arbitrarily, and the image confirmation becomes easy by changing the magnification according to this width. For this reason, it is possible to eliminate the inconvenience in the case where the scaling ratio for the paper width automatically selected as described above is not the scaling ratio required for confirmation.

Next, when it is determined in step 3 that the paper quality priority mode is set (step 3; Y), it is next determined whether or not the priority is given to plain paper (step 15). As a result of this determination, when it is determined that the priority is given to the plain paper (step 15; Y), a reduction ratio is obtained from the width of the set plain paper and the document width detected by the document width sensor (step 16). ). Further, the original length detected by the original length sensor is converted into an original length corresponding to the obtained reduction ratio, and the converted original length is used when the set plain paper is cut by the paper cutting unit 112. The cut length is set (step 17). Next, the roll paper on which the plain paper is set is selected (step 18). The plotter 105 copies the image of the document stored in the memory 102 on the selected plain paper at the obtained reduction ratio, and the plain paper is cut by the paper cutting unit 112 at the obtained cutting length and discharged. The paper is discharged from the paper slot (step 10). According to such a process, when the roll paper set in the paper feed units 108 and 110 is a mixture of plain paper, second original drawing paper, or film paper, the second unit having a high unit price is used. The original copy paper and the film paper are not subjected to the trial copy but are preferentially copied to the plain paper in a trial copy, so that the economical efficiency in the trial copy is improved.

On the other hand, if the priority of the plain paper is judged to be negative in step 15 (step 15; Y), the width of the second original drawing paper or film set by the user by the paper type selection switches 109 and 111, and A reduction ratio is obtained from the document width detected by the document width sensor (step 19). Also, the original length detected by the original length sensor is converted into an original length corresponding to the obtained reduction ratio, and the converted original length is cut into the second original drawing paper or film set by the user. The cutting length when cutting by the section 112 is set (step 20). Then, the set second
Original paper or film roll paper is selected (step 21). The plotter 105 copies the image of the document stored in the memory 102 at the determined reduction ratio on the selected second original drawing paper or roll paper of the film, and cuts the roll paper at the determined cutting length. The paper is cut by the unit 112 and discharged from the paper discharge port (step 10). According to such a process, when it is desired to check the fixability of the target paper type, it is also possible to set the paper type arbitrarily so that the selection based on the paper type is more effective than the selection based on the paper width. Since the priority is given, it is possible to realize the fixability of the test copy.

Next, a second embodiment of the present invention will be described. The second embodiment has the same mechanical and electrical configuration as the first embodiment shown in FIGS. 1 and 2, and the control processing procedure of each unit is shown in FIGS. Therefore, the description of the mechanical and electrical configuration is omitted here. Therefore, the control processing procedure of the second embodiment will be described with reference to the flowcharts of FIGS.

Now, the user operates the operation unit 103 to set the test copy mode. If it is determined that the test copy mode is set (step 31; Y), the document width sensor and the document length of the scanner 101 are set. The width and length of the original are detected by the sensor, and the detected original width and original length are represented by R.
After storing the original in the AM 203, the scanner 101 reads the original, and stores the read image data of the original in the memory 10.
2 (step 32). Next, it is determined whether or not the paper quality priority mode has been set by the user (step 33). If the determination is negative (step 33; N), it is determined whether or not there is an instruction to cancel the magnification. If it is determined (step 34) that there is no instruction to cancel the magnification (step 34; N), it is determined whether or not the paper width designation magnification mode is set (step 35).

If the result of determination in step 35 is that the paper width designation scaling mode has not been set (step 35;
N), from the minimum width of the plurality of roll papers set in the paper feed unit and the document length read by the document length sensor,
A minimum reduction ratio is calculated (step 36). That is,
In step 36, each width of the set roll papers is compared with the length of the document detected by the document length sensor, and the width of the narrowest roll paper among the set roll papers and the width thereof are determined. The minimum reduction ratio (variable magnification) is obtained from the document length. Next, the document width detected by the document width sensor is converted into a document width corresponding to the obtained reduction ratio, and the converted document width is used as the length when the roll paper having the minimum width is cut by the paper cutting unit 112. (Step 37).

Next, the roll paper having the minimum width is selected from the plurality of paper feed units 108 and 110 (step 38). Next, the image data is sent from the memory 102 to the plotter 105. At this time, the image data is reduced so as to have the reduction ratio obtained as described above and rotated by 90 degrees.
Therefore, the plotter 105 copies the image based on the image data on the roll paper of the selected minimum width, and the roll paper is cut by the paper cutting unit 112 at the obtained cutting length and discharged to the paper discharge port. (Step 39). By such a process, as shown in FIG.
Since the entire image can be reduced and copied onto roll paper, roll paper can be saved, and a test copy can be realized in which the layout of the entire image when the two-point instruction erasure or the composite editing mode is used can be easily checked.

When it is determined in step S34 that there is an instruction to cancel the magnification (step 3).
4; Y), the reduction rate is set to “100%”, and the image data is output without rotation (step 40). That is, in this case, the roll paper having the minimum width is determined based on the width of the document detected by the document width sensor and the reduction ratio “100%”, and the length of the document detected by the document length sensor is reduced. The determined roll paper cutting length is determined based on the rate “100%”. Then, the plotter 105 copies the image of the document on roll paper of the minimum width, and the roll paper is cut by the cut length and output from the paper discharge port. According to such processing, when there is no need to change the magnification, the user can cancel the functions of changing the magnification and rotating the image, so that the paper can be saved and the image can be easily checked.

In step 35, when the paper width designation scaling mode is set (step 3).
5; Y), proceed to step 41; In step 41, the minimum reduction ratio is obtained from the width of the selected roll paper and the document length detected by the document length sensor. Next, the document width detected by the document width sensor is converted into a document width corresponding to the obtained minimum reduction ratio, and the converted document width is cut by the paper cutting unit 112 on the selected roll paper. (Step 42). Next, the image data is sent from the memory 102 to the plotter 105. At this time, the image data is reduced to the reduction rate determined as described above,
And rotated 90 degrees. Therefore, the plotter 105 copies the image based on the image data on the selected roll paper, and the roll paper is cut by the obtained cutting length,
The paper is discharged to the paper discharge port (step 39). By such processing, the width of the roll paper can be set arbitrarily, and the image confirmation becomes easy by changing the magnification according to this width. For this reason, it is possible to eliminate the inconvenience in the case where the scaling factor for the paper width automatically selected as described above does not become the scaling factor required for confirmation.

Next, when it is determined in step 33 that the paper quality priority mode is set (step 33; Y), it is next determined whether or not plain paper is given priority (step 43). As a result of this determination, if it is determined that the priority is given to the plain paper (step 43; Y), the reduction ratio is obtained from the width of the set plain paper and the document length detected by the document length sensor (step 44). ). Further, the document width detected by the document length sensor is converted into a document width corresponding to the obtained reduction ratio, and the converted document width is used when the set plain paper is cut by the paper cutting unit 112. The cut length is set (step 45).

Next, the roll paper on which the plain paper is set is selected (step 46). Next, the image data is sent from the memory 102 to the plotter 105. At this time, the image data is reduced so as to have the reduction ratio obtained as described above and rotated by 90 degrees. Accordingly, the plotter 105 copies the image based on the image data on the selected roll paper, and the roll paper is cut by the obtained cutting length and discharged to the paper discharge port (step 39). According to such processing, when the roll paper set in the paper feeding units 108 and 110 is set in a state where plain paper, second original drawing paper, or film paper is mixed,
Since the second original drawing paper or the film paper having a high unit price is not subjected to the test copy but is preferentially copied to the plain paper, the economical efficiency at the time of the test copy is improved.

On the other hand, if the priority of the plain paper is negative in step 43 (step 43; Y), the width of the second original paper or film set by the user and the length of the original detected by the original length sensor Then, a reduction ratio is obtained from the above (step 47). Also, the document width detected by the document width sensor is converted into a document width corresponding to the obtained reduction ratio,
The converted document width is set as a cutting length set by the user when the second original drawing paper or film is cut by the paper cutting unit 112 (step 48). Next, the set second original drawing paper or film roll paper is selected (step 49). Next, the image data is sent from the memory 102 to the plotter 105. At this time, the image data is reduced to the reduction rate determined as described above,
And rotated 90 degrees. Therefore, the plotter 105 copies the image based on the image data on the selected roll paper, and the roll paper is cut by the obtained cutting length,
The paper is discharged to the paper discharge port (step 39). According to such a process, when it is desired to check the fixability of the target paper type, it is also possible to set the paper type arbitrarily so that the selection based on the paper type is more effective than the selection based on the paper width. Since the priority is given, it is possible to realize the fixability of the test copy.
