Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a receiving device, and more particularly, to a receiving device capable of changing the type of recording paper according to a selected mode.

[Related Art] Recording paper of a conventional facsimile apparatus is roughly classified into cut paper and roll paper.

The cut sheet is usually placed in a sheet cassette and mounted on the main body of the apparatus, so that it is easy to set the sheet. After the cut sheet is recorded, its size is constant, which is convenient for managing files and the like. However, since the cut sheets are fed one by one to the recording unit of the apparatus, there is a possibility that a jam occurs during the feeding.

On the other hand, since the roll paper is continuously fed to the recording unit and cut after recording, there is no discontinuous portion in the middle of the paper feeding, and it can be said that the possibility of occurrence of jam is small. However, since it is mounted on the apparatus main body in the form of a roll, setting is not easy, and the cut position differs depending on image data, which is disadvantageous in management after recording.

As described above, both the cut sheet and the roll have advantages and disadvantages, but a normal facsimile apparatus includes one of the recording sheets depending on the application.

[Problems to be Solved by the Invention] In the facsimile apparatus as described above, when the use conditions or the use environment change in one day, there is only one kind of recording paper, which is inconvenient. For example, it is assumed that a facsimile of a cut-sheet type is used with an emphasis on file management because it can be easily recovered even if a jam occurs during a time period when an operator is always present, such as a normal time. However, in this case, a problem of jam is likely to occur in a time zone such as at night when the operator is absent. That is, the power of the facsimile machine is usually turned on so that the information can be received even at night, but if a jam occurs in such a case, the information is received without being recovered, and the information to be recorded is recorded. Is likely to be lost.

If a roll paper type facsimile apparatus is employed to avoid such a problem, the occurrence of jams is reduced, but it is inconvenient to manage information that is frequently received at normal times as recording paper.

The present invention has been made to solve such a problem, and an object of the present invention is to provide a receiving apparatus capable of recording image data on an appropriate recording sheet according to a use state.

[Means for Solving the Problems] A receiving apparatus according to the present invention comprises a time zone setting means for setting a time zone, and a mode setting means for setting a first mode or a second mode according to the set time zone. Receiving means for receiving image data transmitted from outside the apparatus,
Output means for printing out the received image data, first recording paper supply means for supplying first recording paper to the output means, second recording paper supply means for supplying second recording paper to the output means, mode setting Means for supplying the first recording paper from the first recording paper supply means to the output means when the first mode is set, and supplying the second recording paper when the second mode is set. Control means for controlling the supply of the second recording paper from the means to the output means.

Preferably, in the receiving device, the first recording sheet supplied to the output unit when the first mode is set is a roll sheet, and the second recording sheet supplied to the output unit when the second mode is set is a cut sheet.

[Operation] In the present invention, an appropriate recording sheet is supplied according to the selected mode, so that a recording process according to a use state can be performed.

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

This facsimile apparatus has a recording unit 1 and a reading unit in terms of functions.
It is roughly divided into 30.

The recording unit 1 is constituted by a laser beam printer,
The operation will be briefly described below.

First, the data received via the handset 27 connected to the telephone line is replaced by a laser light emission operation of the optical system 4. The photoconductor drum 5 is uniformly charged by the charger 8, and then an electrostatic latent image is formed by irradiating the optical system 4 with a laser beam. The toner of the developing device 9 adheres to the electrostatic latent image. On the other hand, cut sheets are stored in the sheet cassette 2, and cut sheets are fed one by one by rollers or the like. However, instead of the paper feed cassette 2, a roll paper feed unit 15 having a built-in roll paper and cutter installed under the recording unit 1 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 cut sheet to the recording start position, the rollers and the like are reversed to prepare for the next recording. The toner adhered to the photosensitive drum 5 is transferred to paper (cut paper or roll paper) by the transfer charger 10 and fixed by the fixing device 6. The paper on which the fixing has been completed is discharged to the tray 7. The toner that has not adhered to the paper is collected by the cleaner 11, and one printing operation is completed.

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

The original placed on the original tray 20 is detected by a sensor (not shown) based on a transmission command on an operation panel 35 installed on the upper surface of the recording unit 1, and is transmitted by rollers 21 and 22.
The sheets are fed one by one to the position of the sensor 23. Next, the image data of the document is read and converted into digital image data by synchronizing the rotation of the roller 22 by a motor (not shown) with the reading start timing of the fixing type image sensor 24. After the reading is completed, the sheet is discharged to the discharge section 25 by the discharge roller 26. In this embodiment, the rollers 22 and
26 is driven by the same drive system, and discharges the read original in preparation for the next original reading operation. The image information read by the reading unit 30 is transmitted to a telephone line via the handset 27.

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

In the figure, an operation panel includes a numeric keypad group 40 for inputting a telephone number and the like of a transmission destination, a display unit 41 for instructing an operation procedure and displaying a destination telephone number and the like, and a transmission unit after completion of document setting and destination designation. A transmission key 42 for instructing start,
Interrupt key for instructing the addition of a broadcast destination during transmission
43, a broadcast key 44 for performing broadcast transmission, and a non-transmission key for instructing processing not to transmit image data in a predetermined area.
Consists of 45.

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

FIG. 4 is a block diagram showing a configuration of a control unit of the facsimile apparatus of FIG.

 Hereinafter, the configuration and operation will be described.

The control unit mainly includes a communication control CPU 50, an operation panel unit 35, and a printer control unit 55.A communication path for transmitting various mode information and a timing signal line for notifying various timings are provided therebetween. Connected by The communication control CPU 50 is mutually connected to various other blocks as shown in the figure by a bus.

First, when a document is placed on the document tray 20, the document is detected by a sensor of the reading unit 57, and the detection information is transmitted to the CPU 50. Based on the detection information, the CPU 50 operates the operation panel 3
A request for inputting a destination FAX number is displayed on the display unit 41 of No. 5. When the fax number is input, the original is read by synchronizing the motor and the IR unit of the reading unit 57 to read the original.
An image signal for each line is obtained, and one line 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 unit 60 and stored in the compressed image memory 51. When scanning of the original is completed, the CP
U50 calls a facsimile machine on the receiving side through a telephone line via modem 53 and NCU. When the line is connected, the compressed memory stored in the compressed image memory 51 is sent to the compression / expansion unit 60 to be expanded, and stored in the page memory unit 61 as image data before compression. Next, the stored image data is subjected to automatic reduction processing according to the recording paper size unique to the receiving facsimile machine, and is further compressed by the compression / expansion unit 60 according to the encoding method of the receiving facsimile machine. Are stored again 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 as performing compression according to the capabilities of these receiving-side facsimile apparatuses, the obtained compressed data is output to the HDLC analysis unit 52.
After processing according to the HDLC standard, the data is transmitted to the telephone line via the modem 53 and the NCU 54. When all the images have been transmitted, the line is disconnected in accordance with the disconnection procedure, and the transmission process ends.

 Next, the operation at the time of reception will be described.

When the transmitting facsimile apparatus calls this facsimile apparatus via the telephone line, the line is connected in accordance with the communication procedure. When the connection of the line is completed, the image data sent from the transmission-side facsimile apparatus is sent to the HDLC analysis unit 52 via the NCU and the modem, returned to simple compressed data, and stored in the compressed image memory 51. When reception of all the image data is completed, the line is disconnected in accordance with the communication procedure.

After the line is disconnected, the image data is sent from the compressed image memory 51 to the compression / expansion unit 60, where it is sequentially expanded, and
In step 61, data as an actual image is stored. At the same time, the printer control unit 55 is activated by the CPU 50, and the transfer of the image signal from the page memory 61 to the printer control unit starts. However, when the expansion of one page is completed, 1
The expansion of the compression / expansion unit 60 is stopped until the data transfer for the page is completed. This is because it is necessary to prevent overwriting of decompressed data because the page memory section has only one page area.

When printing of all the compressed image data in the recording unit 1 is completed, the receiving operation is completed.

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

First, in step S1, initialization of registers, various input / output ports, various flags, and the like is performed. Next, in step S3, a timer interrupt for periodically calling an interrupt service routine described later is set. Steps S5 to S13 are various check routines for processing each sequence in the interrupt service routine as desired (for example, when reading is performed so that reading is performed). S1
When the processing up to 3 is completed, the flow returns to S5 again, and the same check routine is repeated. Details of each of the check routines will be described later.

FIG. 6 shows a timer interrupt service routine set in FIG.

As shown in steps S21 to S29, this service routine includes five subroutines of transmission, reception, reading, printing and key processing, the details of which will be described later.

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

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

When the night batch flag is set, during the night, the facsimile apparatus stores image data received by the facsimile apparatus in the compression memory unit to a certain fixed amount, and when the certain amount is reached, collectively prints the stored portion. Is being done.
Thus, for example, in this embodiment, since the heater only needs to be temporarily turned on to drive the laser beam printer, the number of times the heater is turned on is reduced, which is advantageous in saving energy.

FIG. 8 is a diagram showing the temperature control of the fixing roller by the heater of the laser printer in a normal time other than at night and on holidays in the facsimile apparatus according to one embodiment of the present invention.

Since the fixing roller recordable T ₁ is arrives in a short period of time,
Heater until Normally the temperature of the roller to the temperature T ₂ slightly lower than the temperature T ₁ is lowered, and ON the heater, and reaches the T ₁
The heater is repeatedly turned ON and OFF so as to maintain the ON state. Further, when the recording operation of the printer is started (time point t ₁ and later), the temperature of the rollers so as to hold the T ₁ as the temperature after the arrival roller T _1, the temperature control of the heater is performed.

FIG. 9 is a diagram showing the temperature control of the rollers by the heater of the laser beam printer at night and on holidays in the facsimile apparatus according to one embodiment of the present invention.

In a standby state in which a recording operation is not performed at night or the like, the heater is turned off. Accordingly, the temperature of the roller is cold T _3. When the need for the recording operation of the printer occurs at time t _2, the heater is turned ON, the temperature of the roller is temperature controlled so as to keep the T ₁ is performed. Therefore, the temperature from the state roller at the normal time takes a long time to reach the T _1, since although the time required is longer in the recording operation, practical processing of the recording sheet is not performed at night or the like defect Does not occur. In addition, since details of the temperature control itself are already known in various systems, they will not be described here.

Here, returning to the flowchart of FIG. 7, if the nighttime batch flag is reset in step S62, the process proceeds to step S63. Then, it is checked whether the amount of the used memory has reached the set amount. When the used memory amount has reached the set amount (YE in step S63)
In S), the nighttime flag is set in step S65. On the other hand, if the used memory amount has not reached the set amount, the process returns without setting the nighttime batch flag.

In step S67, it is checked whether or not there is an image to be recorded (printed).
After confirming the reset state of each of the reading flag, the line transmission flag, and the print flag in 9 to S71, it is determined in step S72 whether the recorded image is a long document. If it is determined that the recorded image is a long document (YE in step S72)
S), in step S73, roll paper, which is recording paper suitable for a long document, is selected. If it is not a long document, step S7
In step 4, a cut sheet that is advantageous for file management or the like is selected. After one of the recording papers is selected, the printing unit is started in step S75 (the power of the heater of the fixing roller is turned on).
Then, in step S77, a print start flag is set. In step S79, the display d shown in FIG. 3 is performed to inform the operator that printing is in progress. If the reading flag is set in step S69, the compression / decompression unit is used for reading, and therefore, the process returns without entering the printing operation.

If the line transmission flag is set in step S70, the process returns without doing anything because the compression / decompression unit is used for transmission. Further, when the print flag is set in step S71, since the printing operation has already been performed, the process returns in this case as well.

If it is determined in step S67 that there is no recording image, the night batch flag is reset in step S81, and the batch print operation ends. In step S83, the printing unit is stopped (the heater is turned off), and in step S85, the display e of FIG.
To inform the operator of the end of the printing operation and return. However, at night or the like, the operator may be absent and this display may be omitted.

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

First, in step S101, it is determined whether or not a document is on the document tray 20. If the original is on the original tray 20,
The process proceeds to step S103. If the original is not on the tray, the process jumps to step S111.

Only when each flag is reset in steps S103, S105, and S107, the process proceeds to step S109, and the reading operation is started by setting the reading start flag. But,
If any of these flags has been reset, the process jumps to step S111. That is, step S103
When the reading flag is set in step S105, it is because reading is already in progress.When the respective flags are set in steps S105 and S107, printing or transmission is in progress and the compression / decompression unit does not use the reading flag. This is because the reading operation cannot be performed.

Next, in step S111, the set state of the reading start flag is determined. When the reading start flag is set,
Proceeding to step S113, display a in FIG. 3 is performed to prompt the operator to input the dial number of the transmission destination. Then, proceeding to step S115, when the input of the dial number is completed,
In order to perform an original reading operation, the processing after step S117 is performed.

In step S117, the leading document is sent to the reading unit. In step S119, the arrival of the document reading unit is detected. If the document has not yet arrived at the reading unit, the process returns as it is, but if the document has arrived at the reading unit, the process proceeds to the next step S121. Various flags are set in step S121, and the reading start flag is reset in step S123. Thereafter, the display f in FIG. 3 is performed in step S125 to notify the operator of the start of the reading operation, and the process returns.

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

First, in step S131, the presence or absence of transmission data is determined. If there is no data to be transmitted, the process directly returns. If there is data to be transmitted, the process proceeds to step S133. Only when all the flags have been reset in steps S133, S135, S136, S137 and S138, the process proceeds to step S139, and the transmission operation is started by setting the line transmission flag. If any one of the flags is reset in steps S133 to S138, the process returns. That is, when the flag is set in steps S133 and S135, transmission cannot be performed because the compression / expansion unit is being used, and when the line reception flag is set in step S136, the line is used for the reception operation. This is because transmission cannot be performed. If the recording restart flag is set to 1 in step S137, it means that the reading of the document has been completed by interrupt transmission, and the transmission process is suspended until the remaining recording operation is completed by restarting the recording. Is done. If the line transmission flag is set in step S138, the operation returns to step S138 because the transmission operation has already been started. Next, the process proceeds from step S139 to step S141,
Delete the previously transmitted compressed data. Thereafter, in step S143, the display g shown in FIG. 3 is performed, and the operator is notified that the transmission has started, and the process returns. It should be noted that the data is deleted at this time, that is, in step S141, in order to prepare for a key input of manual broadcasting, data is not deleted immediately after transmission, and data is held until the next transmission starts. This is to manage this.

Furthermore, in this embodiment, the transmission image data is not the compressed data decompressed and recompressed at the time of the previous transmission, and the original compressed data is retained. The retained data may be any compressed data.

Further, the data can be deleted at any time after the transmission of the next original (in this case, the reading operation is also included in the transmission), at any time, for example, it is detected that the original is set on the original tray. Or when a destination number is set or when reading of a document is started.

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

First, in step S151, it is determined whether a call has been made through a telephone line. When called, step
In steps S153 and S155, the set state of the line transmission flag and the line reception flag is checked to determine whether the line is in use. If it is determined in steps S153 and S155 that the line is being used, the process returns to step S153 since it does not enter the receiving operation. If it is determined in steps S153 and S155 that the line transmission flag and the line reception flag have been reset, the line reception flag is set in step S157 and the reception operation is started. And
In step S159, the display h shown in FIG. 3 is performed to inform the operator that reception is in progress, and then the routine returns.

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

First, time is read in step S173. The time can be detected by a battery-backed clock IC (not shown) connected to the communication control CPU 50. Next, in step S175, it is determined whether the time is between certain two set values (for example, pm 9:00 to am 7:00). If the time is out of the setting, it is determined that the time is night, and the night flag is set in step S179. If the time is outside the setting, it is determined that the time is normal and the night flag is reset in step S177. When the night flag is reset in step S181, the feeding to the recording unit is performed from the cut sheet in step S183, and when the night flag is set, the feeding to the recording unit is performed in step S185. Perform from roll paper. This is because roll paper generally has a lower probability of causing jams than cut paper. That is, if a jam occurs at night, it is difficult to recover the jam because there is no operator, and the probability of losing the received data is high. Therefore, at night, roll paper having a low probability of occurrence of a jam is selected.

The start and end times that determine the set time are
In this embodiment, the setting is made from the DLPSW (not shown), but the setting may be made from the operation panel, for example.

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

In this embodiment, the reason why the compressed data is returned to the decompressed data once at the time of transmission and then returned to the compressed data is that a transmission method called memory transmission is employed. In other words, this method is a method of temporarily storing image data of all originals in a memory at the time of reading before transmission, and then connecting a line with a partner (transmission destination) at the time of transmission. However, at the time of storage in the memory, since the recording capacity (recording size and the like) and the compression method of the other party are not known, the encoding must be performed in a method convenient for the transmission side (for example, a method with high compression efficiency). . Later, if the compressed data does not match the compression method and recording size of the destination at the time of actual communication, the compressed data is expanded again to return to the actual image, and then changed to the compressed data suitable for the receiving side It is necessary to do it.

First, in step S233, the set state of the decompression flag is determined. When the decompression flag is set, the set state of the one-block decompression flag is determined in step S235. One block is a unit composed of several lines of image data. When it is determined in step S235 that the one-block decompression flag has been reset, it indicates the start of one-block decompression operation. Then, the process proceeds to step S237, where the next one block of compressed data is sent to the decompression unit, the decompression operation is set in step S239, and the one-block decompression flag is set in step S241.

If the one-block decompression flag is set in step S235, it indicates that one-block decompression operation is being performed, and it is determined in step S243 whether one-block decompression processing is completed. If the decompression process has been completed, the one-block decompression flag is reset in step S245, automatic reduction is performed in step S247 according to the recording size of the other party (transmission destination), and image processing is performed in step S249 if necessary. Processing (setting of date and time, transmission source, printing function, non-transmission area, etc.) is performed. The details of the image processing will be described later with reference to FIG. Further, in step S251, the decompressed data is temporarily stored in the page memory.
After performing the reset operation of the decompression flag and the setting of the compression flag in steps S253 and S255 in order to perform the compression operation of the block, the process proceeds to step S257. That is, when the decompression of one block is completed, the one block is then compressed,
The operation of returning to the compressed data memory is sequentially performed for all pages.

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

First, the set state of the compression flag is determined in step S257, and if the compression flag is set, step S259
If the compression flag has been reset, the process proceeds to step S277 in FIG. 14B.

In step S259, the set state of the one-block compression flag is determined. If the one-block compression flag is reset, the compression operation is set in steps S261 to S265, and the decompressed data is sent from the page memory to the compression unit, and the one-block compression flag is set. The compression flag is set, and compression of one block is started.
When the one-block compression flag is set (NO in step S259), it is determined in step S267 whether compression of one block has been completed. If the compression is completed, reset the one-block compression flag in steps S269 to S275, transfer the compressed data to the compressed image memory, reset the compression flag, and set the decompression flag to perform the decompression operation next. To step S277.

In step S277, it is determined whether or not the above-described decompression / compression operation has been completed up to the last 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 proceeds to step S291.

In step S291, the set state of the line transmission flag is determined, and if the flag has been reset, the process returns as it is. If the flag has been set in step S291, the process proceeds to step S293, where the set state of the transmission connection completed flag is determined, thereby determining whether or not the line connection with the other party (transmission destination) has been completed. Checked. If the transmission connection completed flag is reset in step S293, the process proceeds to step S331 in FIG. 14C, the connection operation is performed, and if the flag is set, the image data transmission is performed in the processing after step S295. Is performed.

In step S295, it is determined whether the transmission of the image data has been completed. If the transmission has been completed (the image transmission completed flag = 1), the process proceeds to step S317. If the transmission has not been completed, the process proceeds to step S297.

In step S297, the setting of the transmission unit is performed, and the image data is transmitted to the telephone line. Then, in step S301, it is determined whether or not transmission of one page has been completed.
In S303, it is determined whether or not transmission of all pages has been completed. If the transmission of one page has not been completed, the compressed data is continuously transmitted to the transmission unit in step S313.

If the transmission for one page has been completed but not all the pages have been completed, the page is updated in step S309. When transmission of all pages is completed, step S305
To set the image transmission completed flag, reset the transmission disconnected flag, and return.

On the other hand, if the image transmission has ended in step S295 and the transmission disconnection processing has not ended in step S317, the 14D
The transmission disconnection operation in steps S317 to S324 in the figure is performed.

First, a line disconnection process is performed in step S317, and it is determined in step S319 whether the line disconnection process has been completed. If the disconnection processing has been completed, the line disconnection flag is set in step S321, the line transmission flag is reset in step S323, and after returning to the display i shown in FIG. 3, the process returns. If the disconnection processing has not been completed in step S319, the process returns.

On the other hand, if the transmission connection completed flag is not set in step S293, a line connection process is performed in step S331 in FIG. 14C. In step S333, it is determined whether the connection process has been completed. If the connection process has been completed, the process proceeds to step S339, but if the connection process has not been completed, the process returns. In step S339, each flag is initialized. In step S341, the transmission connection completed flag is set, and the process returns.

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

First, in step S351, the setting state of the line reception flag is determined, and it is checked whether the line is being received. If the line is being received, the process proceeds to step S353. If the line is not being received, the process directly proceeds to step S375 in FIG. 15B. In steps S353, 355, and 359, it is determined whether the connection at the time of reception has ended, whether the transmission of the image after the reception connection has ended, and whether the disconnection of the reception after the image transmission has ended, respectively. The process branches to a predetermined step according to the result.

When the line connection process has not been completed (in step S353
(NO), proceeds to step S367, and after performing line connection processing, it is determined in step S369 whether or not the line connection has been completed. If the line connection has been completed, the reception connection completed flag is set in step S371, and the image connection completed flag is set in step S373, and the process returns. If the line connection has not been completed, the process returns.

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

If the image reception start flag has been reset, the process proceeds to step S380, where a predetermined process for storing received image data is performed. In step S381, it is determined whether or not storage of one page has been completed, and in step S383, whether or not storage of all pages has been completed. Step S381
If it is determined that the storage of one page is not completed, the process returns. If storage of all pages has not been completed in step S383, the stored pages are updated. If storage of all pages has been completed, the image reception completed flag is set in step S385, and the process returns.

On the other hand, if the image reception completed flag is set in step S355, the process proceeds to step S357 to perform a line disconnection process. It is determined in step S359 whether or not the disconnection process has been completed. At the end, after the line reception flag is reset in step S361, the display operation of FIG. 3 is performed in step S363 to complete the reception operation, but if the disconnection processing is not completed (NO in step S359), , And the disconnection process is continued.

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

Among them, FIG. 16A shows a control flow of the IR unit and the document conveying motor particularly at the time of reading.

First, when the reading flag is set in step S515, it indicates that the reading sensor and the document conveying pulse motor are being controlled, and the process proceeds to step S517 and subsequent steps.If the reading flag is not set, Proceed directly to step S545 in FIG. 16B.

In steps S517 to S521, it is determined whether reading of one line is completed, whether reading of one block is completed, and whether reading of one page is completed.

If the reading of one line has not been completed in step S517, the process advances to step S541 to determine whether the 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 S543, and the process proceeds to step S545.

When reading of one block is completed in step S519,
Proceeding to step S531, it is determined whether reading of one block has been completed. When reading of one block is completed, after resetting the one-block reading flag in step S533,
Proceed to step S545. If the reading of one block has not been completed in step S531, the process proceeds to step S534, and the processing in steps S534 to S539 is performed. That is, the original for one line is sent in step S534, and the original is sent in step S535.
The data for the line is stored, the setting for reading the next one line is performed in step S537, and the one-line reading flag is set in step S539.

If reading of one page has been completed in step S521, image processing (such as transmission source printing) is performed in step S522.
In step S523, it is determined whether reading of all pages has been completed.

If it is determined in step S523 that reading of all pages has been completed, the document is discharged in step S524, and the process proceeds to step S525.
It is determined whether or not the ejection is completed. If the original has not been completely ejected in step S525,
Proceed to S545. If the discharge has been completed, step S526
After resetting the reading flag in step S527, the image read in step S527 is registered as a transmission image, and after displaying k in FIG. 3 in step S528, the process proceeds to step S545. Steps
If reading of all pages is not completed in S523, step
In S529, a process of sending the next document to the reading unit is performed.

FIG. 16B mainly shows the processing of the compression unit at the time of reading.

First, in steps S545, S547, S549, and S551, a reading compression flag set during reading, a one-line compression flag set during line compression, a one-line compression flag set during block compression, The set state of the one-page compression flag set during compression is determined in each step.

If the reading compression flag is reset in step S545, that is, if there is no need to perform compression at the time of reading, the process returns as it is. If compression at the time of reading is necessary and one line is being compressed in step S547, the flow advances to step S575 to determine whether compression of one line is completed. Only when the compression of one line has been completed, the process returns after resetting the one-line compression flag in step S577.

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 proceeds to step S563 to determine whether compression of one block has been completed. Is determined. At the end, the process returns after resetting the one-block compression flag in step S565. If the compression of one block has not been completed in step S563, one line of compressed data is stored in step S567. Then, in steps S569 to S573, each process of setting the one-line compression flag, transferring the one-line compressed data to the compression unit, and setting the one-line compression command is performed, and then returning.

If it is determined in step S549 that one block is not being compressed, the process proceeds to step S551, and it is determined in step S551 whether one page is being compressed. If one page is being compressed, a block reading flag is set in step S561, and document conveyance during reading is started. If compression is not being performed in step S551,
Proceeding to step S553, it is determined whether the compression processing for all pages has been completed. If the compression process has not been completed for all pages, it is determined in step S557 whether the next document has arrived at the reading unit. If it has not arrived, the process returns as it is. If it has arrived, the one-page compression flag is set and the operation for compressing the next page is started.

If it is determined in step S553 that the compression processing for all pages has been completed, the read compression flag is reset in step S555, and the process returns after ending the compression operation.

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

First, in step S601, the set state of the print start flag is determined. When the flag is not set,
That is, when the print start is not started, the process directly proceeds to step S611. If it is time to start the print start, the set state of the print extension flag is determined in step S603. This is to prevent transfer of image data to the print unit when the decompression operation has not been started.

If the print decompression flag is set in step S603, the print flag is set in step S605.
Send print start command in step S607, step
In S609, each process of resetting the print start flag is performed. If the decompression flag at the time of printing is not set in step S603, the process directly proceeds to step S611.

In step S611, the setting state of the print flag is determined, and if the print flag is not set,
Proceed to step S389 in FIG. If the print flag is set, it is determined in step S613 whether a one-page print start signal has been received from the print unit.
When receiving the signal, 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. If the transfer has not been completed, the process proceeds to step S389. If the transfer has been completed, the process proceeds to step S619, where the set state of the interrupt flag is determined. This interrupt flag is for temporarily stopping the printing so that the operator can read the original during printing, and for performing the remaining printing after the original reading is completed. In this embodiment, the interruption is performed at a break between one page and one page. That is, even if an interrupt request is made during the printing of one page, it is accepted at the end of recording of that page. If the interrupt flag has not been set, the process proceeds to step S625. If it is set, the print flag is reset in step S621, printing is stopped in step S622, and interrupted image data that has not been printed is reregistered as a print image in step S623. Then, after setting the recording restart flag in step S624, the process proceeds to step S625. In step S625, it is determined whether the data transfer for all pages has been completed. If all data transfer has been completed, the print flag is reset in step S627, printing is stopped in step S629, and the process proceeds to step S630. Step S630
Then, it is determined whether or not the transmitted image is the interrupted image data registered in step S623. If the transmitted image is the interrupted image data, the recording restart flag is reset in step S631, and the process proceeds to step S389. When the recording restart flag is set, after the user's original is read by interrupt transmission, the restart of recording has priority.

In this embodiment, the priority is given to the restart of recording after reading the original in the interrupt transmission. However, transmission (to the line) may of course be prioritized. You may.

To perform the former control (transmission priority), a transmission flag before resumption is set in place of the recording resumption flag in step S624, and instead of the control in steps S630 and S631, a transmission flag is set between steps S303 and S305. It is determined whether or not the image is a transmission image in interrupt transmission, and if the image is a transmission image, the transmission flag before resumption is reset, and instead of step S137,
The setting state of the pre-restart transmission flag is determined between steps S70 and S71, and if the flag is set, a process of returning without any operation may be added.

The processing of the steps S389 to S409 in FIG.
This shows a sequence in which compressed image data for one page is expanded and stored in a page memory.

First, in step S389, it is determined whether or not the print decompression flag is set, that is, whether or not a decompression operation is being performed. If the decompression flag at the time of printing is not set, the process returns as it is, but if it is set, the process proceeds to step S393 and subsequent steps.

In steps S393 and S395, it is determined whether the decompression processing for one page and the decompression processing for all pages have been completed in each step. When the decompression process for all pages is completed in step S395, the process returns after resetting the print decompression flag in step S397. If the all-page decompression process has not been completed, the flow advances to step S399 to determine whether transmission of one page of decompressed image data to the printer has been started. Since it cannot enter the next decompression operation, it returns as it is. This is to prevent writing the decompressed data in the same area. If the transmission of the decompressed data to the printer unit has been started, a one-page decompression flag is set in step S400. If the one-page decompression flag is reset in step S393, it means that the decompression processing of one line in the middle of one page has been completed, and therefore, step S4
Proceed to 01 to perform the subsequent processing.

First, in step S401, it is determined whether or not the one-page decompression process 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 S403. If the interrupt flag has been set, the decompression flag is reset in step S404 to stop the decompression processing, and the process returns. 1 in step S401
If the page decompression process has not been completed, one-line compressed data is sent to the decompression unit in step S405 to perform decompression setting for the next line, and the decompression operation is set in step S407. Next, in step S409, the decompressed data is stored in the page memory, and the process returns.

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

First, in step S701, processing related to the input by the key 40 in FIG. 2, that is, the ten keys is performed, and then the process proceeds to step S703. In step S703, it is determined whether or not the ON edge of the transmission key is detected. If the ON edge is detected, the value of the buffer input from the ten keys is registered as the destination number in step S705.

Next, the process proceeds 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 S709 to S713 are performed. That is, step S7
At 09, the set state of the print flag is determined. When the print flag is set, that is, during printing, the process proceeds to step S711, and an interrupt operation is performed at the end of printing of one page. Therefore, display c in FIG. In step S713, an interrupt flag is set. Since the interrupt flag is valid only during printing, if the print flag is reset in step S709, the process jumps to steps S711 and S713.

Next, proceeding to step S715, it is determined whether or not the ON edge of the transmission key 45 has been detected. If an ON edge is detected, the flow advances to step S717 to set a non-transmission registration flag. In step S719, display b in FIG. 3 is performed, and the operator is requested to input the width of the non-transmission area. In this embodiment, the position of the non-transmission area is set as the lower end, but 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, the set state of the non-transmission registration flag is determined. If the non-transmission registration flag is set, it is determined in step S723 whether a non-transmission area has been registered, that is, whether a key input has been performed. If there is a key input, the numerical value of the key input is registered as the non-transmission area width in step S725, and the non-transmission area flag is set in step S727.

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

First, in step S741, it is determined whether or not the ON edge of the manual broadcast key has been detected. If an ON edge is detected, it is determined in step S743 whether or not printing is in progress by checking the print flag. If printing is in progress, the manual broadcast key is not accepted until the printing operation is temporarily stopped using the interrupt key 43, and the process directly proceeds to step S759. If printing is not being performed (YES in step S743), the flow advances to step S745 to set a manual broadcast flag, and in step S747, display a in FIG. 3 is performed to prompt the operator to input a dial number.

In step S751, the setting state of the reading flag is determined. Which image is to be sent is determined according to the set state of the reading flag. That is, if the reading flag has not been set in step S751, the flow advances to step S753 to set the finally read compressed image data as transmission data. On the other hand, if the reading flag has been set in step S751, the flow advances to step S755 to set the image data currently being read as transmission data. Finally, other processing relating to the operation panel is performed in step S759, and the process returns.

FIG. 19 is a flowchart showing the specific contents of the image processing 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 performing non-transmission processing, the process proceeds to step S803,
It is determined whether the process is the first page. In this embodiment, a non-transmission area is provided as an area in which a fax number or the like of a destination can be written, assuming that the operator requests another operator to transmit the non-transmission area. That is, the non-transmission processing is performed only on the processing for the first page of the original document to be transmitted. However, for example, a format may be set such that a certain portion of the document to be transmitted is not always transmitted, and the non-transmission processing may be performed for each page. In step S805, it is determined whether there is a portion corresponding to the non-transmission area in one block expanded in the page memory. If there is a portion corresponding to the non-transmission area, the process proceeds to step S807, where 0 is stored as image data in that area to erase the corresponding area.
(0 indicates white data). In step S809,
Other image processing such as the transmission source is performed, and the process returns.

In the above-described embodiment, the transmission function and the reception function are applied to a facsimile apparatus that is integrated. However, the present invention can be similarly applied to a reception-only facsimile apparatus.

Further, in the above-described embodiment, two types of paper feeding methods, that is, cut paper and roll paper, are adopted as recording paper.
Alternatively, this paper feeding method may be further added.

In the above embodiment, the set time is managed by the time IC. However, a switch or the like for switching the supply of the cut sheet and the roll sheet at the end of the work and the start at the normal time may be provided.

Further, in the above-described embodiment, the set time for using the roll paper is set at night, but the set time may be set at night, not necessarily at night, but on a holiday or during the day.

[Effects of the Invention] As described above, when a specific mode in which there is no person at night or the like is selected, the recording paper suitable for the use state, for example, the roll paper is fed. The recording paper supply unit is selected. Therefore, it is possible to perform reception by taking advantage of the advantages and advantages depending on the type of recording paper, and it is possible to provide a user-friendly receiving apparatus.
