Abstract

PURPOSE:To enable the receiver to receive while activating a merit or an advantage effectively in corresponding to the kind of recording paper, by providing plural recording paper supplying means to respectively supply the intrinsic recording paper to a recording means and a selecting means to select one recording paper supplying means out of the plural recording paper supplying means with responding to a mode selected by a mode switching means. CONSTITUTION:At first, a time is read. The time can be detected by a clock IC (not to be shown in a figure,) for which a battery is backed up, connected to a communication control CPU 50. When the time is out of a set time, the time is judged as a night time and a night flag is set. Then, when the time is within the set time, the time is judged as a normal time and the night flag is reset. When the night flag is reset, the paper is supplied from cut paper to a recording part and when the night flag is set, the paper is supplied from roll paper. It is because a probability to generate jamming is generally low for the roll paper rather than the cut paper.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a receiving device, and more particularly to a receiving device capable of changing the type of recording paper depending on a selected mode.

[Prior Art] Recording paper for conventional facsimile machines can be broadly divided into cut paper and roll paper.

Cut sheets are usually placed in a paper feed cassette and attached to the main body of the apparatus, so they are easy to set, and the size remains constant after recording, which is convenient for file management. However, since the cut sheets are fed one by one to the recording section of the apparatus, there is a risk that a jam may occur during the feeding.

On the other hand, roll paper is continuously fed to the recording unit and cut after recording, so there is no discontinuity in the paper feeding, and it can be said that the possibility of jamming is low. However, since it is attached to the main body of the apparatus in a rolled form, it is not easy to set it up, and the cut position differs depending on the image data, which is disadvantageous in terms of post-recording management.

As described above, both cut paper and roll paper have advantages and disadvantages, but normal facsimile machines are equipped with either type of recording paper depending on the purpose.

[Problems to be Solved by the Invention] The facsimile apparatus as described above is inconvenient because only one type of recording paper is used when the conditions of use or the environment of use change during the day. For example, suppose that during normal times when an operator is always present, a cut-sheet facsimile is used with emphasis on file management because even if a jam occurs, it can be easily recovered. However, in this case, jamming problems tend to occur during times when the operator is absent, such as at night. In other words, facsimile machines are often turned on so that they can receive information even at night, but if a jam occurs in such a case, information will be received without being recovered, and the information that should be recorded will be lost. This is because there is a risk that the information may be lost.

In order to avoid such problems, if a roll paper type facsimile device is adopted, the occurrence of jams will be reduced, but it will be inconvenient to manage information that is received in large quantities in normal times as recording paper.

The present invention has been made to solve this problem, and it is an object of the present invention to provide a receiving device that can record image data using appropriate recording paper depending on the state of use.

[Means for Solving the Problems] A receiving device according to the present invention includes a mode switching unit that can switch to a plurality of modes, a recording unit that records received image data on a recording paper, and a recording unit that each has a unique recording mode. A plurality of recording paper supply means capable of supplying paper to the recording means; and a selection means for selecting one recording paper supply means from the recording paper supply means in response to the mode selected by the mode switching means. It is prepared.

[Operation] In the present invention, since appropriate recording paper is supplied according to the selected mode, recording processing can be performed according to the usage state.

Embodiment FIG. 1 is a sectional view of a facsimile machine according to an embodiment of the present invention.

In terms of functionality, this facsimile machine has a recording section 1 and a reading section 3.
It can be broadly divided into 0 and 0.

The recording section 1 is constituted by a laser beam printer, and its operation will be briefly explained below.

First, data received via the handset 27 connected to the telephone line is replaced by a light emitting operation of the laser of the optical system 4. The photoreceptor drum 5 is uniformly charged by the charger 8, and then an electrostatic latent image is formed by irradiation with a laser beam from the optical system 4.

Toner from the developing device 9 is attached to this electrostatic latent image.

On the other hand, cut paper is stored in paper cassette 2.
Cut sheets are fed one by one by a roller or the like. However, instead of the paper feed cassette 2, a roll paper feed unit 15 installed at the bottom of the recording section 1 and containing a roll paper and a cutter may be used. When the paper is fed from the roll paper 12, after the toner is transferred, the paper is cut into an appropriate length by the cutter 13 and discharged. Further, in order to return the leading edge of the paper after cutting to the recording start position, the rollers and the like are reversed in preparation for the next recording. The toner adhering to the photosensitive drum 5 is transferred to paper (cut paper or roll paper) by a transfer charger 10 and fixed by a fixing device 6. The paver that has been fixed is discharged onto the tray 7. The toner that has not adhered to the paper is collected by the cleaner 1, and one printing operation is thus completed.

Next, the operation of the reading section 30 will be described.

Based on a transmission command from the operation panel 35 installed on the top surface of the recording unit 1, the original placed on the original tray 20 is detected by a sensor (not shown), and the original is moved to the position of the sensor 23 by rollers 21 and 22. They are sent one by one. Next, by synchronizing the rotation of the roller 22 by a motor (not shown) and the reading start timing of the fixing image sensor 24, the image data of the document is read and converted into digital image data. After the reading is completed, the paper is discharged to the discharge section 25 by the discharge roller 26. In this embodiment, the rollers 22 and 26 are driven by the same drive system,
The scanned original is ejected in preparation for the next original reading operation.

The image information read by the reading unit 30 is sent to the handset 27
to the telephone line.

FIG. 2 is a plan view of the operation panel 35 of FIG. 1.

In the figure, the operation panel includes a group of numeric keys 40 for inputting the destination's telephone number, etc., a display section 41 for instructing the operation procedure and displaying the destination's telephone number, etc. Send key 42 for instructing start
, an interrupt key 43 for instructing addition of a broadcast destination during transmission, and a broadcast key 44 for performing broadcast transmission.
It consists of a non-transmission key 45 that instructs processing not to transmit image data of a predetermined area.

FIG. 3 is a diagram showing a specific example of display contents displayed on the display section 41 of FIG. 2.

FIG. 4 is a block diagram showing the configuration of a control section of the facsimile machine of FIG. 1.

The configuration and operation thereof will be explained below.

The control section is mainly composed of a communication control CPU 50, an operation panel section 35, and a printer control section 55, and these are connected to each other by a communication path for transmitting various mode information and a timing signal line for notifying various timings. connected with. The communication control CPU 50 is interconnected with various other blocks shown in the figure via buses.

First, when a document is placed on the document tray 20, the document is detected by the sensor of the reading section 57, and the detection information is sent to the CPU.
50. Based on the detected information, the CPU 50 causes the display section 41 of the operation panel 35 to display a request to input the destination's FAX number. When the fax number is entered,
While synchronizing the motor and IR unit of the reading section 57,
By reading the original, image signals for each line are obtained, and each line of data is sent to the buffer memory 59. At the same time, the image data in the buffer memory is compressed by the compression/expansion section 60 and stored in the compressed image memory 51. When the reading of the original is completed, the CPU 50 connects the modem 5
3 and the NCU 54, the facsimile machine on the receiving side is called through the telephone line. Once the line is connected,
The compressed memory stored in the compressed image memory 51 is sent to the compression/expansion section 60, expanded, and stored in the page memory section 61 as uncompressed image data. Next, the stored image data undergoes automatic reduction processing according to the recording paper size specific to the receiving facsimile device, and is further compressed by the compression/decompression unit 60 according to the encoding method of the receiving facsimile device. , are again stored in another memory area of the compressed image memory 51. These expansion and compression operations are performed alternately in units of one block consisting of several lines of data.

At the same time, compression is performed according to the capabilities of the receiving facsimile machine, and the resulting compressed data is processed by the HDLC analysis unit 52 according to the HDLC standard, and then sent to the telephone line via the modem 53 and NCU 54. Ru. Once all images have been sent out, follow the cutting instructions.
The line is disconnected and the transmission process ends.

Next, the operation during reception will be described.

When the sending facsimile machine calls the present facsimile machine through the telephone line, the line is connected according to the communication procedure. When the line connection is completed, the image data sent from the sending facsimile device is sent to the HDLC analysis section 52 via the NCU and modem, converted back to simple compressed data, and then stored in the compressed image memory 51. When the reception of all image data is completed, the line is disconnected according to the communication procedure.

After the line is disconnected, the compressed image memory 51 is transferred to the compression/decompression unit 60.
The image data is sent to and sequentially expanded there, and the data is stored in the page memory 61 as an actual image. At the same time, the printer control section 55 is activated by the CPU 50, and the transfer of image signals from the page memory 61 to the printer control section begins. However, once the expansion for one page is completed, the expansion by the compression/expansion unit 60 is stopped until the data transfer for one page is completed. This is because the page memory section only has an area for one page, so it is necessary to prevent overwriting of decompressed data.

In this way, when printing of all compressed image data in the recording section 1 is completed, the receiving operation is completed.

FIG. 5 is a main flowchart showing the general control of the communication control CPU 50 shown in FIG.

First, in step S1, initial settings of registers, various input/output ports, various flags, etc. are performed. Next, step S3
A timer interrupt is set to periodically call the interrupt service routine shown later.

Steps 85 to 81B are various check routines to ensure that each sequence in the interrupt service routine is processed as desired (eg, reading is performed when desired). When the processing up to 813 is completed, the process returns to S5 and the same check routine is repeated.

Details of each check routine will be described later.

FIG. 6 is a service routine for the timer interrupt set in FIG. 5.

As shown in steps 821 to S29, this service routine consists of five subroutines: transmission, reception, reading, printing, and key processing, the details of which will be described later.

FIG. 7 is a flowchart showing specific contents of the print check subroutine of FIG.

First, in step S61, the set state of the nighttime flag is determined. The meaning of the night flag itself will be described later. If the night flag is set, step S6
In step 2, the set state of the night batch flag is determined.

When the night batch flag is set, the image data received by the facsimile machine is stored in the compressed memory unit up to a certain amount during the night, and when the certain amount is reached, the stored portion is printed all at once. is being carried out. As a result, in this embodiment, for example, the heater only needs to be turned on temporarily to drive the laser beam printer, which reduces the number of times the heater is turned on, which is advantageous in terms of saving energy.

FIG. 8 is a diagram showing the temperature control of the fixing roller by the heater of the laser printer in a facsimile machine according to an embodiment of the present invention during normal times other than nighttime and holidays.

Because the fixing roller arrives at the recordable T in a short time,
When the temperature of the roller drops to T2, which is slightly lower than the normal temperature T, the heater is turned on, and the heater is turned on and off so that the heater remains on until it reaches T.
FF is being repeated. Furthermore, when the printing operation of the printer starts (after time t1), the temperature of the heater is controlled so that the temperature of the roller reaches T1 and is maintained at T1 as the temperature of the roller.

FIG. 9 is a diagram showing temperature control of the roller by the heater of the laser beam printer during nighttime, holidays, etc. in a facsimile machine according to an embodiment of the present invention.

During standby when no recording operation is being performed, such as at night, the heater is turned off. Therefore, the temperature of the roller is room temperature T3. When the printer needs to perform a recording operation at time t2, the heater is turned on and temperature control is performed to maintain the roller temperature at T1. therefore,
It takes longer for the roller temperature to reach T than under normal conditions, so the time required for the recording operation becomes longer, but the actual processing of the recording paper is not done at night, etc., so this may cause problems. do not have. Further, since various methods are already known, the details of the temperature control itself will not be discussed here.

Returning to the flowchart of FIG. 7, if the nighttime collective flag has been reset in step S62, the process proceeds to step 363. Then, a check is made to see if the amount of used memory has reached the set amount. When the amount of used memory has reached the set amount (YES in step 863), the night batch flag is set in step S65. On the other hand, if the amount of used memory has not reached the set amount, the night batch flag is not set and the process returns.

In step S67, it is checked whether there is an image to be recorded (printed), and if there is an image to be recorded, step S67 is performed.
After checking the reset states of the reading flag, line transmission flag, and print flag in steps 69 to S71, it is determined in step S72 whether the recorded image is a long original.

When it is determined that the recorded image is a long document (step S
(YES in step 72), and in step 873, roll paper, which is a recording paper suitable for long documents, is selected. If the document is not a long document, a cut sheet, which is advantageous for file management, etc., is selected in step S74. After one of the recording papers is selected,
In step S75, the printing unit is activated (power of the fixing roller heater, etc. is turned on), and in step S77, a print start flag is set. In step S79, the display d shown in FIG. 3 is displayed to notify the operator that printing is in progress. Note that when the reading flag is set in step S69, the compression/expansion section is used for reading, so the process returns without entering the printing operation.

If the line transmission flag is set in step S70, the compression/expansion section is used for transmission, so the process returns without doing anything. Further, if the print flag is set in step S71, the print operation has already been performed, so the process returns directly in this case as well.

If it is determined in step S67 that there is no recorded image, the night batch flag is reset in step S81, and the batch printing operation is ended. In step S83, the printing section is stopped (heater OFF), and in step S85, the third
A diagram e is displayed to notify the operator of the end of the printing operation, and the process returns. However, at night,
Since the operator is absent, this display may be omitted.

FIG. 10 is a flowchart showing specific contents of the reading check subroutine of FIG.

First, in step S101, it is determined whether a document is on the document tray 20 or not. If the document is on the document tray 20, the process advances to step 8103, but if the document is not on the tray, the process jumps to step S111.

Only when each flag has been reset in steps 810B, S105, and S107, the process advances to step S109;
The reading operation is started by setting the reading start flag. However, if any of these flags has been reset, the process jumps to step S111.

In other words, when the reading flag is set in step 3103, this is because reading is already in progress, and step S1
This is because when each flag is set in step S107, printing or transmission is in progress and the compression/expansion section is being used, so the reading operation cannot be performed.

Next, in step S111, it is determined whether the reading start flag is set. If the reading start flag is set, the process advances to step 8113, where display a in FIG. 3 is displayed to prompt the operator to input the dial number of the destination. Then, the process proceeds to step S115, and when the input of the dial number is completed, the process proceeds to step S115 to perform a document reading operation.
Processing after step 17 is performed.

In step S117, the first original is sent to the reading section. In step S119, the arrival of the document at the reading unit is detected. If the document has not yet arrived at the reading section, the process returns, but if the document has arrived at the reading section, the process advances to the next step S121. In step S121, various flags are set, and in step 8123, the reading start flag is reset. After that, step S12
At step 5, the display f shown in FIG. 3 is displayed to inform the operator that the reading operation has started, and then the process returns.

FIG. 11 is a flowchart showing specific contents of the transmission check subroutine of FIG.

First, in step 8131, it is determined whether there is transmission data. If there is no data to send, return as is, but if there is data to send, proceed to step 8133.
Proceed to. Step 8133, Step 8135, Step 8136, Step 8137 and Step 8138
Only when both flags are reset in step 8139, the transmission operation is started by setting the line transmission flag. These steps 8133
If any of the flags in steps 8138 to 8138 have been reset, the process returns directly. In other words, when the flag is set in steps 8133 and 8135, the compression/expansion section is in use, so transmission cannot be performed, and when the line reception flag is set in step S136, the line is used for reception operation. This is because transmission cannot be performed because the When the recording restart flag is set to 1 in step 8137, it means that reading of the document has been completed by interrupt transmission, so the transmission process is put on hold until the remaining recording operation is completed by restarting recording. be done. If the line transmission flag is set in step 8138, the transmission operation has already started, and the process returns immediately. Next, from step 8139 to step S
The process advances to step 141 and the previously transmitted compressed data is deleted.

After that, in step 8143, the display g in FIG. 3 is performed,
Returns after notifying the operator that transmission has started. Note that the reason why data is deleted at this point, that is, in step S141, is to prepare for the key human effort required for manual broadcasting, so data is not deleted immediately after transmission, but is retained until the next transmission begins. This is to manage this.

Further, in this embodiment, the original compressed data is held as the transmission image data, rather than the compressed data that was expanded and recompressed during the previous transmission, but the data to be held may be any compressed data.

Furthermore, the data can be deleted at any time, as long as it is at least after the start of the next document transmission (in this case, the reading operation is included in the transmission); for example, when it is detected that the document has been placed in the document tray. The reference may be when the destination number is set, or when reading of the document starts.

FIG. 12 is a flowchart showing specific contents of the reception check subroutine of FIG.

First, in step S151, it is determined whether there is a call through the telephone line. When there is a call, in steps 8153 and S155, the set state of the line transmission flag and line reception flag is checked to determine whether or not the line is in use. If it is determined in steps 8153 and S155 that the line is in use, the receiving operation cannot be started and the process returns directly. If it is determined in steps 815B and S155 that the line transmission flag and line reception flag have been reset, the line reception flag is set in step S157 and a reception operation is started. Then, in step S159, the display h shown in FIG. 3 is displayed to notify the operator that reception is in progress, and then the process returns.

FIG. 13 is a flowchart showing specific contents of the nighttime processing subroutine of FIG.

First, in step 8173, the time is read. The time can be detected by a battery-backed clock IC (not shown) connected to the communication control CPU 50. Next, in step S175, the time is determined to be between two certain set values (for example, 9:00 p.m. to 9:00 a.m.).
7:00). If the time is outside the setting, it is determined that it is night time, and step S1
A nighttime flag is set in step S79, and if it is within the setting, it is determined that it is normal time, and the nighttime flag is reset in step S177. If the night flag is reset in step S181, the paper is fed to the recording unit from the cut sheet in step 8183, and if the night flag is set, paper is not fed to the recording unit in step S185. Start from a roll of paper.

This is because rolled paper generally has a lower probability of jamming than cut paper. In other words, if a jam occurs at night, it is difficult to recover because the operator is absent, and there is a high probability that received data will be lost. Therefore, at night, select roll paper that has a low probability of jamming.

In addition, in this embodiment, the start and end times are set using the DLPSW (not shown).
The setting may be performed, for example, from an operation panel.

14A to 14D are flowcharts showing specific contents of the transmission routine of FIG. 6.

This embodiment uses a transmission method called memory transmission, which converts compressed data once back into decompressed data and then back into compressed data during transmission. That is, this is a method in which the image data of the entire document is temporarily stored in a memory during reading before transmission, and then a line is connected to the other party (destination) at the time of transmission.

However, at the time of storage in memory, the recording capacity (recorded size, etc.) and compression method of the other party are not known, so the sending side has no choice but to encode using a method convenient for it (for example, a method with high compression efficiency). .

Later, during actual communication, if the compressed data does not match the compression method or recording size of the destination, the compressed data is decompressed once again to return to the actual image, and then changed to the compressed data that suits the receiving side. This is because it is necessary.

First, in step 8233, the set state of the decompression flag is determined. If the decompression flag is set, the set state of the 1-block decompression flag is determined in step 8235. Note that one block is a unit composed of several lines of image data. If it is determined in step 8235 that the one block expansion flag has been reset, this indicates the start of one block expansion operation. Then, the process proceeds to step 8237, where the next block of compressed data is sent to the decompression section, and decompression operation is set in step S239.
In step S241, a 1 block expansion flag is set.

When the one block expansion flag is set in step 8235, it indicates that one block expansion operation is being performed, and in step 8243 it is determined whether or not one block expansion processing has been completed. When the decompression process has been completed, the 1 block decompression flag is reset in step S245, automatic reduction is performed according to the recording size of the other party (destination) in step S247, and image processing is performed if necessary in step S249. Processing (date and time, sender, print function,
settings such as non-transmission areas). Details of this image processing will be described later with reference to FIG. 19. Further, in step S251, the decompressed data is temporarily stored in the page memory, and then in order to compress that one block, the decompression flag is reset and the compression flag is set in step S253, and then step S255 is performed.
Proceed to 257. That is, when the decompression of one block is completed, that one block is then compressed and returned to the compressed data memory again, which is sequentially performed for all pages.

Steps S257 to S275 relate to the decompression operation, but are almost the same sequence as the compression operation.

First, in step S257, the set state of the compression flag is determined, and if the compression flag is set, step S257 is performed.
259, and the first when the compression flag is reset.
The process advances to step S277 in Figure 4B.

In step S259, it is determined whether the 1-block compression flag is set, and if the 1-block compression flag is reset, the compression operation is set in steps 8261 to 265, the decompressed data is sent from the page memory to the compression section, and the 1-block compression flag is reset.
Set the block compression flag and start compressing one block. When the 1-block compression flag is set (No in step S259), 1 is set in step S267.
It is determined whether or not compression of the block is completed.

When the compression has been completed, the 1 block compression flag is reset in steps 8269 to S275, and after the compressed data is transferred to the compressed image memory, the compression flag is reset, and then the expansion flag is set to perform the expansion operation. The process then proceeds to step S277.

In step S277, it is determined whether the above-described expansion and compression operations have been completed for all pages up to the final page.

When the operation is completed, the compression method change flag is reset in step S279, the line transmission flag is set in step S280, and the process advances to step S291.

In step S291, the set state of the line transmission flag is determined, and if the flag is reset, the process returns directly. If the flag is set in step S291, the process advances to step 8293, and by determining the set state of the transmission connected flag, it is determined whether or not the line connection with the other party (transmission destination) has been terminated. Will be checked.

If the transmission connected flag is reset in step 8293, the process advances to step 8331 in FIG. 14C, where a connection operation is performed, and if the flag is set,
Image data is transmitted in the processing from step S295 onwards.

In step S295, it is determined whether the transmission of image data has ended. If the transmission has been completed (image transmission completed flag -1), the process advances to step S317, and if the transmission has not been completed, the process advances to step S297.

In step S297, the transmitter is set and the image data is transmitted to the telephone line. And step S301
In step 8303, it is determined whether transmission of one page has been completed, and in step 8303, it is determined whether transmission of all pages has been completed. If the transmission for one page has not been completed, the compressed data is continuously sent to the transmitter in step 8313.

If transmission for one page has been completed but not all pages have been transmitted, the page is updated in step S309. When all pages have been sent, proceed to step S.
The process advances to 305, sets the image transmission completion flag, resets the transmission disconnection completion flag, and then returns.

On the other hand, when the image transmission is completed in step S295 and the transmission disconnection process is not completed in step S317, the transmission disconnection operation in steps 8317 to S324 in FIG. 14D is performed.

First, line disconnection processing is performed in step S317, and it is determined in step S319 whether or not the line disconnection processing has been completed. If the cutting process has ended, step S32
The line disconnected flag is set in step 1, and the line transmission flag is reset in step 8323. After displaying the display i shown in FIG. 3, the process returns. If the cutting process is not completed in step S319, the process returns directly.

On the other hand, if the transmission connection completed flag is not set in step 8293, line connection processing is performed in step 8331 of FIG. 14C. In step 8333, it is determined whether the connection process has ended. If the connection process has ended, the process advances to step S339, but if the connection process has not ended, the process returns directly. Step 83
In step S39, each flag is initialized, and in step S341, the transmission connection completion flag is set, and then the process returns.

15A and 15B are flowcharts showing specific contents of the reception routine of FIG. 6.

First, in step S351, the set state of the line reception flag is determined, and it is checked whether or not line reception is in progress. If the line is being received, the process advances to step 8353, but if the line is not being received, the process continues to step S375 in FIG. 15B.
Proceed to. In steps 8353, 355, and 359, it is determined whether the connection at the time of reception has ended, whether the transmission of the image has ended after the reception connection, and whether the reception disconnection has ended after the image transmission. The process branches to a predetermined step depending on the determination result.

When line connection processing is not completed (step 8353)
If No), the process advances to step S367, where a line connection process is first performed, and then it is determined in step S369 whether or not the line connection has been completed. If the line connection has been completed, a reception connection completed flag is set in step S371, an image connection completed flag is set in step 8373, and the process returns.

If the line connection is not terminated, return directly.

If the line connection has been completed but image reception has not been completed, the process advances to step S375 in FIG. 15B, and first the set state of the image reception start flag is determined. When the image reception flag is set, the receiving section is initialized in step S377, the image reception start flag is reset in step S379, and the process returns.

Also, when the image reception start flag is reset,
Proceeding to step S380, a predetermined process for storing the received image data is performed. In step S381, it is determined whether storage for one page has been completed, and in step 8383, it is determined whether storage for all pages has been completed. If it is determined in step S381 that storage for one page has not been completed, the process returns directly. Step 838
If all pages have not been stored yet in step S385, the stored page is updated, and if all pages have been stored, step S385
After setting the image received flag in , each program returns.

On the other hand, if the image reception completion flag is set in step S355, the process advances to step S357, and line disconnection processing is performed. Step S determines whether the cutting process has been completed or not.
359. At the end, the line reception flag is reset in step S361, and then step 8363
Display j in FIG. 3 is performed to complete the reception operation, but if the disconnection process is not completed (NO in step S359)
) returns as is and continues the disconnection process.

16A and 16B are flowcharts showing specific contents of the reading routine of FIG. 6.

Among them, FIG. 16A particularly shows the control flow of the IR unit and document conveyance motor during reading.

First, if the reading flag is set in step S515, this indicates that the reading sensor and document transport pulse mode are being controlled, and the process proceeds to steps S517 and subsequent steps. However, if the reading flag is not set, The process directly advances to step S545 in FIG. 16B.

In steps 8517 to S521, it is determined whether reading of one line is completed, reading of one block is completed, and reading of one page is completed.

If reading of one line has not been completed in step S517, the process advances to step S541, where it is determined whether reading of one line has been completed. Only when reading of one line has been completed, the one line reading flag is reset in step 8543, and then the process advances to step S545.

When reading of one block is completed in step S519, the process advances to step 8531, and it is determined whether reading of one block is completed. When the reading of one block is completed, the one block reading flag is reset in step S533, and then the process advances to step S545. Step 8531
If reading of one block is not completed, the process advances to step 8534, and the following steps 8534 to 8539 are performed. That is, in step 8534 one line of the original is sent, in step 8535 the data for one line is stored, in step 8537 settings are made to read the next line, and in step 8539 the one line reading flag is set. It is done.

If one page has been read in step S521,
In step S522, image processing (such as printing of the sender) is performed, and in step 8523, it is determined whether or not all pages have been read.

If it is determined in step 8523 that all pages have been read, the document is ejected in step S524, and it is determined in step S525 whether or not ejection is complete. If the ejection of the document is not completed in step S525, the process directly advances to step S545. When the ejection is completed, the reading flag is reset in step S526, the read image is registered as a transmission image in step S527, and the display k shown in FIG. 3 is performed in step S528, and then the process proceeds to step S545 . If reading of all pages has not been completed in step S523, processing for sending the next document to the reading section is performed in step S529.

FIG. 16B mainly shows the processing of the compression section during reading.

First, steps S545, S547, S549, S55
1. Read compression flag set when reading, 1 line compression flag set during 1 line compression, 1 line compression flag set during 1 block compression, 1 page compression set during page compression. The set state of the flag is determined at each step.

When the reading compression flag is reset in step S545, that is, when reading compression is not necessary,
Return as is. If compression is required during reading and one line is being compressed in step S547,
Proceeding to step s575, it is determined whether compression of one line is completed. Only when the compression of one line has been completed, the one line compression flag is reset in step S577, and then the process returns.

If it is determined in step S547 that one line is not being compressed, and if it is determined in step S549 that one block is being compressed, the process advances to step 8563;
It is determined whether compression of one block is completed. At the end of the process, the one block compression flag is reset in step S565 and the process is turned around. If compression of one block is not completed in step 8563, one line of compressed data is stored in step s567. Then, in steps 8569 to 8573, the 1 line compression flag is set,
The process transfers the 1-line compressed data to the compression section and sets the 1-line compression command, and then returns.

If one block is not being compressed in step S549,
The process advances to step S551, and in step S551 it is determined whether one page is being compressed. If one page is being compressed, a block reading flag is set in step s561, and document transport during reading is started. If compression is not in progress in step S551, the process advances to step 8553, where it is determined whether compression processing for all pages has been completed. If the compression process for all pages has not been completed, it is determined in step s557 whether the next document has arrived at the reading section. If the page has not arrived, the page returns as is; if it has arrived, the 1-page compression flag is set and the next page is compressed.

When it is determined in step 8553 that the compression process for all pages has been completed, the read compression flag is reset in step s555, and the process returns after completing the compression operation.

17A and 17B are flowcharts showing specific contents of the print routine of FIG. 6.

First, in step S601, the set state of the print start flag is determined. If the flag is not set, that is, if the print start is not activated, the process directly advances to step S611. If it is the time of print start, it is determined in step 8603 whether the printing expansion flag is set. This is to prevent image data from being transferred to the print section when the decompression operation has not started.

If the print expansion flag is set in step 8603, the print flag is set in step S605, the print start command is sent in step S607, and the print start flag is reset in step S609. If the printing expansion flag is not set in step 8603, the process directly advances to step S611.

The set state of the print flag is determined in step S611, and if the print flag is not set, the process advances to step S389 in FIG. 17B. If the print flag is set, it is determined in step 8613 whether a one-page print start signal has been received from the print unit.

If the signal is received, transfer of one page data is started in step S615. In step S617, it is determined whether the transfer of one page has been completed, and if the transfer has not been completed, the process advances to step S389. If the transfer has been completed, the process advances to step S619, and the set state of the interrupt flag is determined. This interrupt flag is used to temporarily stop printing so that the operator can read the document during printing, and to perform the remaining printing after the document has been read. In this embodiment, the interruption is performed at the break between one page and the other.

That is, even if an interrupt request is made during the printing of one page, it will only be accepted when the recording of that page is finished.

If the interrupt flag is not set, step S62
Proceed to step 5. If set, the print flag is reset in step S621, printing is stopped in step S622, and interrupted image data whose printing has not been completed is re-registered as a print image in step 8623.

After setting the recording restart flag in step S624, the process advances to step S625. In step s625, it is determined whether data transfer for all pages has been completed.

Step S when all data transfer is completed
627, reset the print flag, step S629
The printing is stopped at step 8630.
Proceed to. In step 8630, it is determined whether the transmitted image is the interrupted image data registered in step 8623, and if it is the interrupted image data, the recording restart flag is reset in step 8631, and then step S3
Go forward 89. When this recording restart flag is set, priority is given to restarting recording after the user's original is read by interrupt transmission.

In this embodiment, priority is given to restarting recording after reading the document in interrupt transmission, but of course transmission (to the line) may be given priority, or transmission to the line may be performed at the same time as reading. You can.

In order to perform the former control (transmission priority),
In step S624, a pre-restart transmission flag is set instead of the recording restart flag, and instead of the control in steps 8630 and 8631, it is determined between steps 8303 and 8305 whether or not the image is to be transmitted in interrupt transmission. If so, reset the pre-resume transmission flag, and instead of step 8137, determine the set state of the pre-resume transmission flag between steps S70 and 871, and if the flag is set, do nothing and return. Just add some processing.

The processing of steps 8389 to S409 in FIG. 17B shows a sequence in which one page of compressed image data is expanded and stored in the page memory.

First, in step S389, it is determined whether or not the expansion flag during printing is set, that is, whether or not the expansion operation is in progress. If the printing expansion flag is not set, the process returns directly, but if it is set, the process proceeds to step 8393 and subsequent steps.

In steps 8393 and S395, it is determined in each step whether the decompression process for one page has been completed or whether the decompression process for all pages has been completed.

When the decompression process for all pages is completed in step S395, the print decompression flag is reset in step S397, and then the process returns. Furthermore, if all page decompression processing has not been completed, the process advances to step S399, where it is determined whether or not the sending of one page's worth of decompressed image data to the printer has started; if the sending has not started, , it cannot proceed to the next decompression operation, so it returns as is.

This is to prevent decompressed data from being written in the same area. If the sending of decompressed data to the printer unit has started, a one page decompression flag is set in step S400. When the one-page decompression flag is reset in step 8393, it means that decompression processing for one line in the middle of one page has been completed, so step S40
Proceed to step 1 and perform the subsequent processing.

First, in step S401, it is determined whether the decompression process for one page has been completed. If the decompression has been completed, the one-page decompression flag is reset in step S402, and then the set state of the interrupt flag is determined in step S8403.

When the interrupt flag is set, in order to stop the decompression process, the decompression flag is reset in step S404, and then the process returns. If the decompression process for one page is not completed in step S401, one line of compressed data is sent to the decompression section in step S405 in order to perform decompression settings for the next line, and decompression operation is set in step S407. Next, in step S409, the expanded data is stored in the page memory, and then the process returns.

18A and 18B are flowcharts showing specific contents of the key processing routine of FIG. 6.

First, in step S701, processing related to input using the key 40 in FIG. 2, that is, the numeric keypad, is performed, and then step
Proceed to 703. In step 8703, it is determined whether or not the ON edge of the transmission key is detected. If the ON edge is detected, in step S705, the buffer value input from the numeric keypad is registered as the destination number.

Next, the process advances to step S707, where it is determined whether or not the ON edge of the interrupt key 43 has been detected, and only when detected, the processes of steps 8709 to 8713 are performed. That is, the set state of the print flag is determined in step S709. When the print flag is set,
That is, during printing, the process advances to step S711, and since an interrupt operation is performed when printing of one page is completed, display C in FIG. 3 is displayed to inform the operator of this, and then,
At step 8713, an interrupt flag is set. Furthermore, since the interrupt flag is valid only during printing, step S70
If the print flag is reset in step S9, steps S711 and S8713 are jumped to.

Next, the process advances to step S715, and it is determined whether the ON edge of the transmission key 45 has been detected.

When an ON edge is detected, the process advances to step S717, where a non-transmission registration flag is set, and in step S719, display b in FIG. 3 is performed to request the operator to input the width of the non-transmission area. In this embodiment, the position of the non-transmission area is set at the lower end, but of course, other areas such as the lower right corner may be set as the non-transmission area. If the ON edge of the non-transmission key is not detected in step S715, steps S717 and S719 are jumped.

In step S721, it is determined whether the non-transmission registration flag is set. When the non-transmission registration flag is set, it is determined in step 8723 whether or not a non-transmission area has been registered, that is, there has been a key input. If there is key manual input, the numerical value based on the key input is registered as the non-transmission area width in step S725, and a non-transmission area flag is set in step S727.

The processing after step S741 in FIG. 18B is a flow related to the processing of the manual broadcast key (key 44 in FIG. 2).

First, in step S741, it is determined whether the ON edge of the manual broadcast key has been detected.

When an ON edge is detected, it is determined in step 8743 whether or not printing is in progress by checking the print flag. If printing is in progress, the manual broadcast key will not be accepted until the print operation is temporarily stopped using the interrupt key 43, and the process directly advances to step S759. If printing is not in progress (YES in step 8743)
), the process advances to step S745 to set the manual broadcast flag, and in step S747 display a shown in FIG. 3 is displayed to prompt the operator to input a dial number.

In step S751, the set state of the read flag is determined. Which image to send is determined depending on the set state of the reading flag. That is, if the read flag is not set in step S751, step S875
Proceed to step 3 and set the last read compressed image data as transmission data.

On the other hand, if the reading flag is set in step S751, the process advances to step S755, and the image data currently being read is set as transmission data. Finally, step S75
At step 9, other processing related to the operation panel is performed and the process returns.

FIG. 19 is a flowchart showing specific details of the image processing process in step S249 of FIG. 14A.

First, in step S801, the set state of the non-transmission area flag is determined, and it is determined whether or not to perform non-transmission processing. When non-transmission processing is to be performed, the process advances to step 8803, where it is determined whether or not the processing is for the first page.

In this embodiment, a non-transmission area is provided as an area in which a recipient's FAX number, etc. can be written, assuming that an operator requests another operator to send a message.

That is, the non-transmission process is limited to the first page of the document to be sent. However, for example, a format may be set in which a certain portion of the document to be sent is always not sent, and the non-send process may be performed for each page. In step S805, it is determined whether or not there is a portion corresponding to the non-transmission area in one block expanded to the page memory. If there is a portion corresponding to the non-transmission area, the process advances to step S807, and in order to erase the corresponding area, 0 is written in that area as image data (0 indicates white data). In step S809, other image processing such as the source is performed and the process returns.

In the above embodiment, the present invention is applied to a facsimile machine in which the transmitting function and the receiving function are integrated, but the present invention can be similarly applied to a receiving-only facsimile machine.

In addition, in the above embodiment, two types of paper feeding methods, cut paper and roll paper, are used as the recording paper, but it is also possible to combine it with a paper feeding method using other types of paper feeding, such as continuous paper. Further paper feeding methods may be added.

Further, in the above embodiment, the set time is managed by the time IC, but it is also possible to provide a switch or the like to switch the supply of cut paper and roll paper at the end and start of normal business operations.

Further, in the above embodiment, the set time for using roll paper is set at night, but it is not necessarily at night, but may also be set at times such as going out, even on holidays or during the day.

[Effects of the Invention] As explained above, in this invention, when a specific mode such as at night when there are no people is selected, recording paper suitable for the usage condition is fed, such as roll paper. A recording paper supply means is selected.

Therefore, it becomes possible to perform reception that takes advantage of the merits and advantages of each type of recording paper, resulting in an easy-to-use receiving device.
