DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording apparatus for automatically selecting a plurality of cassettes for recording.

[0002]

2. Description of the Related Art In a conventional facsimile apparatus or a recording apparatus provided in a copying machine, a method of selecting one cassette from a plurality of cassettes is as follows. In this method, the cassettes that can be selected are limited from the above cassettes, and then the optimum cassette for the apparatus is selected from the length of the sub-scan.

[0003] The priority of cassette selection in the apparatus has always been determined.

[0004]

However, in the above-mentioned conventional example, when the condition for selecting the cassette is changed, for example, the optimum length of the sub-scan is set regardless of the width (main scan) of the recorded image. When a user wants to select a cassette, there is a drawback in that the method of first limiting the cassette based on the length of the main scan cannot be used.

Further, if a plurality of conditions are added as conditions for selecting a cassette and judgment is sequentially made for each condition, flexibility in setting conditions can be obtained. The same determination must be repeated many times, such as scanning → sub-scanning → main scanning, which has the disadvantage that the selection logic becomes very complicated.

Further, even when the number of cassettes increases, the determination of the cassette must be added to the determination part of the main scanning and the sub-scanning, so that there is a drawback that it becomes more complicated.

Further, as described above, in the conventional apparatus, since the priority order of the cassette selection is determined, there is a disadvantage that the priority order of the cassette selection cannot be changed depending on the purpose of use.

It is an object of the present invention to provide a recording apparatus capable of easily selecting a cassette.

FIG. 1 is a block diagram schematically showing a facsimile apparatus provided with a recording apparatus according to one embodiment of the present invention.

The facsimile apparatus includes a control circuit (CPU) 4 for controlling the entire apparatus, a memory section 7 for storing various programs and data, a reading section 3 for reading an original,
A recording unit 5 for outputting an image on a recording paper, an operation unit 6 having an LCD display and various operation keys, a modem (MODEM) 1 for modulating and demodulating transmitted / received data, and an NCU 2 for connecting a line to the telephone or the modem 1 And

The recording unit 5 is set with three cassettes 1 to 3 of an upper stage, a middle stage, and a lower stage.

In such a configuration, first, at the time of copying, an original is read by the reading unit 3 and the image is stored in the memory unit 7. Here, the control circuit 4 calculates the cassette information from the image, the width and the length information in accordance with the priority of the cassette selection of the apparatus, selects the optimum cassette, and outputs the recording image from the recording unit 5. I do.

At the time of reception, NCU is transmitted from the communication line.
2. The received image data is stored in the memory unit 7 via the modem 1, and thereafter, a recorded image is output in the same manner as in copying.

In the operation unit 6, the priority of the cassette selection of the apparatus can be changed by a registration switch (not shown).

FIGS. 2 to 4 are flowcharts showing a cassette selecting method according to the present embodiment.

First, in S21, if there is paper in the upper cassette, the type is set to the upper cassette, the size is set to the upper cassette size (S22), and the cassette information of the upper cassette is calculated (S23). If there is no paper in the upper cassette, the upper cassette information is set to 0 (S24) and excluded from the selection.

Next, in S25, if there is paper in the middle cassette, the type is set to the middle and the size is set to the middle cassette size (S26), and the cassette information of the middle cassette is calculated (S27). . If there is no sheet in the middle cassette, the middle cassette information is set to 0 (S28) and excluded from the selection.

Thereafter, the calculation of the cassette information is similarly performed for the lower cassette (S29 to S32).

[0022] Thereafter, in S33, if it is value set in the upper cassette information, sets the information of the upper cassette in the variable a ₁ (S34), further, if the value in the lower cassette information is set (S35 ), sets the lower cassette information to the variable b ₁ (S36), the processing of the cassette comparison (S37), compares the values of the upper and lower, and selects a high priority cassette.

[0023] Then, the selection result in the case of the upper priority sets (S38), the upper cassette information to the variable a ₁ (S39). Also, if the selection result has the lower priority,
Sets lower cassette information to the variable a ₁ (S40).

Next, if the middle cassette information is set (S41), sets the middle cassette information to the variable b ₁ (S42), performs a cassette comparison again (S43), selects the highest priority cassette I do.

Further, in the above S35, if the information of the lower cassette is not set, if the value in the middle cassette information is set (S44), sets the middle cassette information to the variable b ₁ (S45), the cassette Comparison (S4
In the process 6), the values in the upper and middle stages are compared, and a cassette with a higher priority is selected.

If no value is set in the middle cassette in S44, the upper cassette is automatically selected (S47).

Further, in S33, if the value in the upper cassette information is not set, if the value in the lower cassette information is set (S48), sets the lower cassette information to the variable a ₁ (S49), the following to, if the value in the middle cassette information is set (S50), sets the middle cassette information to the variable b ₁ (S51), the processing of the cassette comparison (S52), by comparing the values of the lower and middle,
Select a cassette with a higher priority.

If no value is set in the middle cassette in S50, the lower cassette is selected (S53).

In S48, if no value is set in the lower cassette and if a value is set in the middle cassette information (S54), the middle cassette is selected (S55).

If no value is set in the middle cassette in S54, no cassette is selected.

With the above processing, a cassette is selected.

In the cassette comparison process, the magnitudes of the cassette information of the variable a ₁ and the variable b ₁ are compared, and a cassette having a larger value is returned as a selection result.

FIGS. 5 to 7 are flowcharts showing the processing for calculating the cassette information in the cassette selection of the present embodiment.

First, an initial value of cassette information (FIG. 8) is set (S60), and the cassette is set to a letter (LTR).
If the size is set (S61) and the LTR priority is set by the registration switch (S62), the sub-scanning priority flag in the cassette information is set (S63).

If the cassette is legal (LGL) size (S64) and the LGL priority is set by the registration switch (S65), the sub-scanning priority flag is set similarly (S63).

Next, the inside of the recorded image is the A series (S6).
6) If the cassette for which the calculation is being performed is of the B series (S67), a margin flag in the cassette information is set (S68). When the cassette is of the A series, the margin flag is not set.

Next, if the number of lines of the image is within the same-size recording range (S69), the state of the same-size flag is left at the initial setting, and if it exceeds the same-size range and falls within the cut-off range, (S70), a cutoff flag is set (S71).

If the value exceeds the truncation range and falls within the reduction range (S72), a reduction flag is set (S7).
3) If reduction priority is set by the registration switch (S74), a reduction priority flag is set (S7).
5). If the reduction priority is not set, the reduction priority flag is not set.

Thereafter, a reduction ratio is calculated from the number of lines and the size of the cassette (S76) and set in the cassette information.

If it does not fall within the reduction range, a division flag is set (S77), the number of divisions is calculated from the number of lines and the size of the cassette, its complement is taken and set in the cassette information (S78). ).

In S66, if the width of the recorded image is the B series, the flow proceeds to S33. If the cassette size is the A series (S79), the B4 → A4 reduction flag is set (S80), and the number of lines of the image is set. If it is within the B4 → A4 reduction range (S81), the state of the same-size flag is left at the initial setting, and if it exceeds the B4 → A4 range and is within the B4 → A4 truncation range (S82), Is set (S83).

If the value exceeds the truncation range,
The processing of S84 to S90 is performed as in S72 to S78.

In S79, the cassette is
If it is the series size, the process moves to S69, and the processing after S69 is performed.

When the calculation of the cassette information is completed by the above processing, if the currently calculated cassette is the upper cassette (S91), the cassette information is set in the upper cassette information (S92), and the cassette is changed to the lower cassette. If there is (S93), the cassette information is set in the lower cassette information (S94), and if it is any other cassette, the cassette information is set in the middle cassette information (S95), and the process ends.

FIG. 8 is an explanatory diagram showing the contents of the cassette information in detail.

The priority order of cassette selection is as follows: 1: 1>Truncation>Margin>Reduction> B4 → A4 Reduction> Division, and the flag indicating each state is set as shown in the figure.
The order is divided, B4 → A4 reduction (reduction priority), equal magnification, margin, and truncation.

As for the reduction priority, the mode is set to the reduction priority mode by the registration switch, and this bit is set only when the reduction is performed.

Regarding the sub-scanning priority, L is set by the registration switch.
This bit is set only when the cassette is set to the TR (LGL) priority mode and the cassette is the LTR (LGL).

Thereafter, the reduction ratio and the complement of the number of divisions are entered. For the reduction ratio, a value of 0 to 100% is entered in hexadecimal, and for the complement of the division number, the value of (64-division number) is given. Is entered in hexadecimal.

Finally, the cassette status information is A5,
A4, LTR, LGL, B5, and B4 are in the order of priority of sub-scanning.

Note that the initial set values at the time of calculating the cassette information are as shown in the figure.

FIG. 9 is an explanatory diagram showing a typical example showing the state of the priority order of cassettes.

The one with the highest priority is 1 which is the same size and has no condition. Next, condition 2 with truncation, condition 3 with margin, condition 4 with reduction, condition 4 with B4 → A4 reduction, condition 6 with division at the end, and so on. .

Incidentally, even if the number of types of cassette sizes (A3, B3, B6-) increases as a condition for cassette selection, it can be dealt with by adding the cassette status to the cassette information.

As a condition for selecting a cassette, A3 →
Even if the conditions of B4 reduction, A3 → A4 reduction, enlargement / actual magnification, and enlargement ratio increase, it is possible to cope by adding a flag or enlargement ratio to the cassette information.

In addition, even if the conditions for selecting various cassettes increase, it can be dealt with by increasing the structure of the cassette information to three words, four words, and so on.

Further, even when the number of cassettes is increased, it can be dealt with by adding the cassette information of the cassette.

[0058]

According to the present invention , cassette information indicating the priority order is determined for each cassette of the recording apparatus, and the contents are compared to select the cassette. Therefore, the number of cassettes is reduced. Even if it increases, there is an effect that a cassette can be easily selected.

Further, according to the present invention , by changing the priority of cassette selection of the recording apparatus by the registration switch, there is a cassette that can record a reduced size of a certain document and a cassette that can record the original at the same magnification. In this case, there is an effect that it is possible to specify which output is given priority.

According to the present invention , by changing the registration switch, when there is a cassette that can record in A4 and a cassette that can record in LTR (the same recording condition), it is possible to specify which one should be output with priority. effective.
