FIGS. 2 and 7 to 12 are flowcharts showing an example of the cassette selecting method according to the present embodiment.

First, in S21, the cassette selection information is initialized. Here, parameters such as the document width, the number of lines, fixed reduction / automatic reduction, and resolution are set as selection information. Next, the priority of the recording paper size is determined according to the main scanning width of the document (S22 to S32).

FIG. 3 shows the priorities of typical recording paper sizes. Here, the smaller the numerical value is, the higher the priority is. The shorter the size of the recording paper with the same main scanning width as the original image> the longer the size of the recording paper with the same main scanning width as the original image> With margin in the main scanning direction Size of short recording paper that can be recorded in the main scanning direction> long recording paper size that can be recorded with margins in the main scanning direction> short recording paper size that can be recorded by standard reduction> In order. The device settings are LTR (Letter) and LGL (Legal)
When the priority is given, LTR and LGL are given priority over A4 in the recording paper size priority order.

In S33, the priority of the cassette selection phase is determined. The cassette selection phase includes a selection phase 1 to a selection phase 6. The priority order changes depending on the setting of the cassette selection mode of the apparatus, and the main scanning priority which gives priority to the recording paper size having the same width as the main scanning width of the original, or the optimum sub scanning length regardless of the main scanning width. There is sub-scan priority for selecting the recording paper size, and the like.

FIG. 5 shows the selection operation in each selection phase, and FIG. 6 shows the priority of the cassette selection phase in the main scanning priority and the sub scanning priority. In the selection phase 5 and the selection phase 6, the priority of the short-width priority shown in FIG. 4 is adopted as the priority of the recording paper size.

Next, of the recording paper size priorities described above, sizes other than the recording paper size set in the apparatus are excluded from selection candidates, and recording paper size information is created (S34). In S35, each selection phase is executed according to the priority of the cassette selection phase determined in S33. When one selection phase ends, the selection result is evaluated (S36). If the recording paper size and the cassette level have been determined, the selection end procedure of S38 and S39 is performed, and the cassette selection operation ends. If not, proceed to the next selection phase.

After repeating all the cassette selection phases by repeating S35 to S37, if the end of the selection phase is confirmed in S37, the selection result is determined as NG and the cassette selection operation is ended (S40).

With the above processing, it is possible to select an optimum recording paper size for a document in accordance with the priority order according to the setting of the apparatus.

Next, the cassette selection phase in the cassette selection of this embodiment will be described in detail.

FIG. 7 shows cassette selection in recording on one sheet of recording paper having the same main scanning width and margin / standard reduced recording on one sheet of recording paper having different main scanning widths (selection phase 1 and selection phase 3). 9 is a flowchart illustrating an operation of a phase.

First, the number of divisions (one division) and the S
The recording paper size information determined in S34 is set (S4
1, S42). Next, it is determined whether the current cassette selection phase is to select one recording sheet having the same main scanning width or to select one recording sheet having a different main scanning width (S4).
3). In the former case, when the main scanning width of the target recording paper size is equal to that of the original (S44), in the latter case, when the main scanning width of the target recording paper size is different from that of the original (S45), The respective cassette selection information is created (S46).

As a result of the cassette selection information obtained here,
When it is determined that recording is possible to the target size (S4
7) The size is inserted into the priority sequence of the recording paper candidates (S48, S49), and the process proceeds to S50. If it is determined that recording on the target size is not possible, the process proceeds from S47 to S50.
Proceed to.

In S50, it is determined whether or not the selection target size has ended. If it is determined that the selection has ended, the process proceeds to S51. If not, the selection target size is switched to the next priority size (S52), and S43. And the above operation is repeated.

In S51, it is determined whether or not a recording paper candidate exists. If there is, the process proceeds to S53 and S54, and if not, the current selection phase is ended and the process proceeds to the next phase. If it is determined in S53 and S54 that there is paper in the cassette stage accommodating the highest priority recording paper candidate size, cassette selection information is created again (S55), and the selected recording paper size and the selected The cassette stage information is set, and the phase ends (S56).

If the cassette stage has no paper, S5
When the next recording paper candidate exists, the size of the recording paper is set (S58), and the same processing is performed.
If it is determined that the next recording paper candidate does not exist (S5
7) End the current selection phase and move to the next phase.

FIG. 8 shows the cassette selection phase in divided recording on recording paper of the same main scanning width and the margin / standard reduced division recording (selection phase 2 and selection phase 4) on recording paper of different main scanning width. It is a flowchart showing the operation.

In the cassette selecting operation here, S5
From 9 to S69, the same processing as in the selection phase at the time of single-sheet recording is performed, and a recording paper selection candidate size is selected. As a result of the above processing, if the recording paper candidate size does not exist (S70), the number of divisions is increased by 1 (S78). If the number is within the predetermined maximum number of divisions (S79), the process returns to S59 and the selection operation is performed again. To start. If the maximum number of divisions is exceeded, the current phase is ended and the process moves to the next phase.

If there is a recording paper candidate size in S70, the cassette status of each candidate size is checked according to the priority order (S73). If the cassette has paper, cassette selection information is created again (S74), the selection result is set, and the phase ends. If there is no paper in the cassette, the state of the cassette having the next highest priority in the recording candidate size is checked. If it is (S79), the process returns to S59 and starts the selection operation again. If the maximum number of divisions has been exceeded, the current phase is ended and the process proceeds to the next phase.

FIG. 9 is a flowchart showing the operation of the cassette selection phase in the case where recording is performed on one sheet of recording paper within the reduction range regardless of the main scanning width (selection phase 5).

First, the recording paper sizes in the recording paper size information are rearranged in the shortest priority order shown in FIG. 4 (S80). In this phase, cassette selection information is created for each recording paper size irrespective of the main scanning width (S83 to S88). If there is a paper candidate, the selected recording paper size and the selected The cassette stage information is set, and the phase ends (S89-S95). Otherwise,
Each recording paper size of the recording paper size information is returned to the normal priority and the process proceeds to the next phase (S96).

FIG. 10 is a flowchart showing the operation of the cassette selection phase when recording is performed on a recording sheet having the minimum number of divisions regardless of the main scanning width (selection phase 6).

In the cassette selecting operation here, S9
From 7 to S105, the same processing as in the selection phase 5 is performed to determine the recording paper candidate size. As a result of performing the above processing, if the recording paper candidate size does not exist (S10
6) The number of divisions is increased by 1 (S113). If the number is within the predetermined maximum number of divisions (S114), the process returns to S99 and the selection operation is started again. If the maximum number of divisions is exceeded, the current phase is ended and the process moves to the next phase.

If there is a recording paper candidate size in S106, the cassette status of each candidate size is checked according to the priority order (S108). If the cassette has paper, cassette selection information is created again (S109), the selection result is set, and the phase ends (S110).
If there is no paper in the cassette, the state of the cassette of the recording candidate size having the next highest priority is checked (S11).
1, S112), if there is no recording paper candidate, the number of divisions is set to 1
The number is increased (S113). If the number is within the predetermined maximum number of divisions (S114), the process returns to S99, and the selection operation is started again. If the maximum number of divisions has been exceeded, the current phase is ended and the process proceeds to the next phase.

Next, the cassette selection information creation processing in this embodiment will be described in detail with reference to the flowchart shown in FIG.

First, the number of sub-scan lines cas line that can be printed at the same magnification in the effective recording range of the target recording paper size is calculated (S116). Here, the number of lines is converted according to the resolution of the original image, and correction for image truncation is also performed. If the number of divisions is two or more, the number of lines x the number of divisions is set to the number of lines that can be recorded at the same magnification (S117, S118). Next, the main scanning width of the original image is compared with the main scanning width of the recording paper size (S119), and the main scanning width width2 of the recording paper size is changed to the main scanning width width1 of the original image.
In the above case, the standard reduction rate R1 is set to 100% (S1
20). When the main scanning width width1 of the document image is larger than the main scanning width width2 of the recording paper size,
Assuming that the fixed reduction ratio R1 = width2 / width1% (S121), the fixed reduction flag is set (S12).
2). Next, based on the cas line, the number of recordable lines 1 within the reduction range is calculated (S12).
3). FIG. 12 is a flowchart showing the operation.

When the fixed reduction is set as the reduction mode, the fixed reduction ratio R1 × the fixed reduction ratio R0 is set as the allowable reduction ratio R (S138). If automatic reduction is set, the standard reduction rate R1 × the maximum reduction rate Rmax is set as the allowable reduction rate R (S139). If reduction recording is prohibited, the calculation is performed with the fixed reduction ratio R0 = 100%.

As a result of the above calculation, if the allowable reduction ratio R is equal to or less than the maximum reduction ratio Rmax, the allowable reduction ratio R is set to the maximum reduction ratio Rmax (S140, S141). Therefore,
Permissible recording line number line1 = Number of lines recordable at the same magnification, cas line / permissible reduction rate R (S14)
2).

Next, a reduction ratio R3 at the time of recording is calculated. In the case of fixed reduction and with fixed reduction, the recording reduction ratio R3 is set to the allowable reduction ratio R (S126). If the fixed reduction is not accompanied by the fixed reduction, the recording reduction ratio R3 is set to the fixed reduction ratio R0 (S127). In the case of automatic reduction, first, the number of lines cas line that can be printed at the same size as the target recording size and the number of original lines line2 are compared (S128). R1 (S1
29) Otherwise, the record reduction rate R3 = cas
Line / line 2 is set (S130). Here, in the case of recording with fixed reduction, the recording reduction ratio R3 is compared with the fixed reduction ratio R1, and the smaller value is used as the recording reduction ratio R1.
3 (S131 to S133).

In step S134, the allowable line number line1 is compared with the original line number line2, and
If the value is equal to or more than e2, the selection information is set to be recordable, and the reduction ratio is set to R3 (S135). In other cases, the selection information cannot be recorded (S136).

In the above embodiment, the recording apparatus of a facsimile apparatus has been described as an example. However, the present invention is not limited to this, and can be widely applied to recording apparatuses in copying machines and other information processing apparatuses. is there.
