The internal control status is set, and the next step S
In step 412, a normal status transmission process indicating that the processing of the reserve unit command has been normally completed (good status transmission in accordance with the SCSI standard is performed). [Release unit command processing] This command is executed by the On-Line
The mode is a command for shifting from a state in which command processing from the host computer 15 side is preferentially processed to an Off-Line mode operating as a normal facsimile machine.

If it is determined in step S402 that the command is a release command, then in step S420 Off-Li is issued.
The processing of shifting to the mode of ne is performed. If the command from the host computer 15 is being executed, the execution is interrupted, the internal status is shifted to the Off-Line mode, the normal status is sent out in step S421, and the process ends. [Information Request Command Processing] This command not only notifies the host computer of the functions of the apparatus, but also notifies the reason for the abnormality when a confirmation status is selected.

If it is determined in step S403 that the command is an information request command, an internal information notification process is performed in step S430, a normal status transmission process is performed in step S431, and the command process ends.

Step S404 is processing when an undefined command is received for all logical units, and a confirmation status is selected.

FIG. 14 shows a list of parameter groups operated as all logical units. <Processing of Scanner Command> FIG.
FIG. 15 is a flowchart showing detailed processing of various commands to the scanner unit 6 in 308. FIG.
The following is a list of parameter groups operated by the scanner command. [Scanner Information Request Command Processing] This command is a command for notifying the host of information of the scanner unit 6, and specifically notifies the presence / absence of a document, the size of a document, and the presence / absence of a failure. If it is determined in step S501 of FIG. 5A that the command is a scanner information request command, the flow advances to step S510.
Sends the scanner information to the host computer,
In step S511, a normal status is sent, and a series of processing is terminated. [Read Parameter Set Command Processing] This command is a command for receiving a designation of a read mode before receiving a read request command, and accepts settings such as a resolution and an encoding method. If it is determined in step S502 that the command is the command, the process proceeds to step S5.
At step 20, a predetermined parameter is received, and step S521 is executed.
Sends a normal status and ends the process. [Read Request Command Processing] This command is a command for, after receiving the above-mentioned read parameter set command, reading a document actually set in the scanner and storing the image data in the storage device 11 in the facsimile apparatus.

If it is determined in step S503 that the command is the command, in step S531, the state of the scanner and the presence / absence of setting of reading parameters (if not specified, the scanner is operated with a preset default value) are checked, and the state cannot be executed. If so, in step S533, a confirmation status is sent, and the process ends. However, if the execution is possible, a disconnection process is performed in step S532, and the logical connection of the host computer is temporarily released, so that another command (particularly, a stop command) is accepted. Subsequently, a reading process is performed in step S534 using the function of the facsimile machine, and a file registration process is performed in the file management unit 10 in the next step S535.

Thus, the image can be read by the scanner in the facsimile apparatus by designating the resolution, the encoding method, and the like from the host, and the image can be managed as a file.

After the file registration processing is completed, step S
At 536, a reselection process is performed, and a logical connection with the host computer is made again. After that, step S53
At step 7, it is determined whether the result of the reading process is normal or abnormal. If the result is abnormal, a confirmation status is selected at step S538. However, if the processing result is normal, step S53
By transmitting the normal status in step 9, a series of processing is completed. [File information request command processing] This command is used to execute the file information created by executing the read request command,
For example, it is used to notify a file management id, a file size, and the like to the host computer.

As the processing, step S50 in FIG.
If it is determined in step S4 that the command is a file information request command, the file information is transmitted in step S540, and the normal status is transmitted in step S541, and the process ends. [Stop Command Processing] This command is used to interrupt the reading operation during the reading operation of a document based on the reading request command.

If the stop command is determined in step S505, the reading process is interrupted in step S550, and a normal status is transmitted in step S551 to notify the host that the stop command has been executed.
After the reading process is interrupted in step S552, post-processing is executed, and the process ends. [Status Request Command Processing] This command is issued after sending a confirmation status to other scanner command processing, and notifies the host computer of the cause of the issuance of the confirmation status.

If it is determined in step S506 that the command is the command, predetermined status information is transmitted in step S560, and a normal status is transmitted in step S561, and the process ends.

Note that step S507 indicates that a confirmation status is issued when an undefined scanner command is received. <Printer Command Processing> FIG. 6 is a flowchart showing processing relating to printer command processing. FIG. 16 shows a parameter group operated by a printer command. [Printer Information Request Command Processing] This command is a command for notifying the host computer of the presence / absence, size, and failure of recording paper in the printer unit 7.

If it is determined in step S601 in FIG. 6A that this command is the command, in step S601,
A process for transmitting such information is performed, and a normal status is transmitted in step S611, and the process is terminated. [Print Output Request Command Processing] This command is used to selectively print out a document managed in the facsimile machine.

If it is determined in step S602 that the command is the command, in step S620, the status of the printer, the presence / absence of the designated file, and the like are checked. If an abnormality is detected, the confirmation status is sent in step S620. To end the processing. However, if the result of the check is normal, the logical connection with the host computer is temporarily cut off in step S622, and step S623.
To print out the specified file. After the printout process is completed, a logical connection with the host computer is made again in step S624, and if the result of the printout process is normal in the determination in step S625, a normal status sending process is performed in step S626. However, if the result of the print output process is abnormal, a confirmation status transmission process is performed in step S627, and the process ends.

Thus, a document managed as a file in the facsimile apparatus can be output by a printer in the facsimile apparatus according to an instruction from the host. [Stop Command Processing] This command is a command used to interrupt the processing during execution of the print output request command.

If it is determined in step S603 in FIG. 6B that the command is the present command, print output interruption processing is performed in step S630, and normal status transmission processing in the sense that execution of this command has been completed is performed in step S631. . Thereafter, in step S631, a series of processing is completed by executing post-processing accompanying execution of the print output request being interrupted. [Status Request Command Processing] This command is used to send a confirmation status to other printer command processing and then notify the host computer of the cause of the issuance of the confirmation status.

As a process, if it is determined in step S604 that the command is the command, predetermined information is transmitted in step S640, a normal status is transmitted in step S641, and the process ends.

Step S605 indicates that confirmation status transmission processing is performed when an undefined printer command is received. <Image Command Processing> FIG. 7 is a flowchart showing processing relating to image command processing. FIG. 17 shows parameters used in the image command. [Attribute Attribute Command Processing] This command is used to create a file with a data write command described below. For example, image information, image size, resolution, encoding form, character If the data is data, the code system or the like is specified in advance, and the information is used to manage the information as a file attribute.

As the processing, step S70 in FIG.
If it is determined in step S1 that the command is the command, a predetermined attribute designation parameter is received in step S710, a normal status is transmitted in step S711, and the process ends. [Data Write Command Processing] This command is used to transfer the data from the host to the facsimile apparatus when creating a document file in the facsimile apparatus. In this embodiment, data of a plurality of pages can be managed for one file, but one document and one file are assumed. When a file is created, before issuing this command, it is a rule that the specification of file attributes is declared in advance by the attribute specification command described above.

In creating one file, there is a possibility that this command is issued a plurality of times, and a flag indicating whether the end of one page data and whether the file data is final or not is set. It can be specified as a parameter in the command. These flags enable management on a page basis and on a document basis.

Hereinafter, specific processing will be described with reference to a flowchart.

If it is determined in step S702 of FIG. 7A that this command is the command, in step S720, the processing status in the facsimile machine is checked. This is to check whether the attribute of the file has been clarified by the attribute specification command and whether there is sufficient storage capacity to create the file. If it is determined that the file is abnormal, Step S721
Sends a confirmation status and terminates the process.

At this point, even if there is already processed document data, step S732 described below is performed.
If the file registration process in is not performed normally, the data is discarded unconditionally.

If it is determined in step S720 that the processing status is normal, then in step S722, document data is fetched into a facsimile. If there is an abnormality such as insufficient storage capacity at this point, step S724 is performed.
Then, the confirmation status is sent, and the process ends. However, if it is determined in step S723 that the processing result is normal, it is determined in step S725 whether or not the data is page boundary data. If the data is continued as page data, a normal status is transmitted in step S726. Then, it waits for reception of the next data write command.

If the determination in step S725 is YES, in step S727 in FIG. 7-2, close processing for file management is once performed as page data, and in subsequent step S728, is there any abnormality in the close processing? See if it is. If a problem has occurred here, the confirmation status is sent in step S729, but if there is no problem, it is determined in step S730 whether or not the process ends as a document file.

If the page data is sent continuously, the result of the determination in step S730 is NO.
In step S731, a normal status is sent, and a new data write command is waited for. However, if the processing is completed as a document, registration processing as a file is performed in step S732, and if the processing is determined to be normal in step S733, a normal status is transmitted in step S735.

On the other hand, if it is determined in step S733 that there is an abnormality, a confirmation status is sent out in step S734, and a series of file creation processing ends. [File specification command processing] This command is used to specify a file to be transferred before issuing a data read command which is an execution command for transferring document data managed in the facsimile apparatus to the host computer. Command.

If it is determined in step S703 of FIG. 7C that this command is the command, predetermined file designation information is received in step S740, and the normal status is sent out in step S741, followed by terminating the process. [Data Read Command Processing] This command is a command for transferring the file data specified in advance by the above-described file specification command to the host computer.

If it is determined in step S704 that the command is the present command, first, in step S750, the internal status related to the file data transfer processing is confirmed. If the result is abnormal, the confirmation status is transmitted in step S751. The process ends. However, step S75
If the result of the check at 0 is normal, the data transfer processing is executed at step S752, and at the next step S753,
If there is no more data to be transferred before the specified transfer byte count is reached, a confirmation status is sent in step S754, and the process ends. However, if there is transmission data, a normal status is transmitted in step S755, and the process ends. [File Information Request Command Processing] This command is used to notify the host computer of file information managed in the facsimile machine.

In the present embodiment, three types of commands are prepared when requesting file information, and information corresponding to the three types is notified to the host computer. FIG.
Shows these commands.

Command type is "file ID list request"
In the case of, a list of file IDs managed in the facsimile apparatus is notified as information. In the case of "individual file information request", a predetermined file ID and a page number are specified at the same time, and the file information as shown in FIG. 20 is notified to the host. In the case of “request for latest file information”, the file information of the file created last is
0 is notified to the host computer.

The file information request command is prepared for a scanner command, an image memory command, and a communication command. However, if the command type is “latest file information request”, a read request command, a data write command, The latest file information of each file created when the reception request command (including the polling reception command) is executed is notified. As described above, in the present embodiment, information stored as a file in a facsimile apparatus can be extracted in a form that is easy to operate on the host side.

In the command processing, if it is determined in step S705 of FIG. 7-4 that the command is the present command, in step S760, the file information corresponding to the command type described above is sent to the host computer, and step S771 is executed.
Sends a normal status and ends the process. [File delete request command] This command is for performing the delete process of the specified file. If it is determined in step S706 that this command is the present file, the delete process of the specified file is performed in step S770, and step S771 is performed. Sends a normal status and ends the process. If the specified file does not exist, the normal status transmission process is performed. [Status Request Command Processing] This command is issued when a confirmation status is sent to other image memory command processing, and notifies the host computer of the cause of the issuance of the confirmation status.

If it is determined in step S707 that the command is the command, predetermined information transmission processing is performed in step S780, and a normal status is transmitted in step S781 to end the processing.

Step S708 indicates that a confirmation status is issued when an undefined image memory command is received. <Communication Command Processing> FIG. 8 is a flowchart showing communication command processing, and FIG. 18 shows a parameter group operated by the communication command. [Session Open Command Processing] This command is for calling processing to a predetermined partner terminal and controlling the communication procedure up to the session layer.

If it is determined in step S801 of FIG. 8A that the command is the command, in step S820, a call process is performed using the address information, terminal characteristics, and terminal capability information designated by the host computer. In step S821, the RSSP is received as a processing result, and if it is determined that the calling process has been completed normally, a normal status is transmitted in step S823. However, at step S821, R
If connection to the session layer cannot be made end-to-end, such as when the SSN is received, step S82
In step 2, the confirmation status is sent, and the process ends. [Remote Terminal Information Request Command Processing] This command is used to notify the host computer of information notified from the remote terminal by RSSP or the like when the remote terminal is connected to the session layer in the session open command processing described above. belongs to.

If it is determined in step S802 that the command is the present command, it is confirmed in step S830 that the connection to the session layer has been established. If there is no data to be transmitted, a confirmation status is transmitted in step S831, and the processing is terminated. I do. However, if the status check is normal in the judgment in step S830, the partner terminal information is sent out in step S832, the normal status is sent out in step S833, and the process ends. The host computer receiving the partner terminal information displays this information on the display unit. As a result, it is possible to confirm whether or not the call can be reliably made to the desired destination, and to confirm whether or not the partner apparatus has the processing capability of the communication application that the host operator wants to process. Then, the document can be transmitted and received based on the confirmed information. [Session Close Command Processing] This command is for performing processing from the state of connection to the session layer to the line disconnection processing.

If it is determined in step S803 that the command is the command, disconnection processing starting from transmission of CSE is executed in step S840, and normal status is transmitted in step S841, and the processing ends. [Communication Result Request Command Processing] This command is for notifying the host computer of a communication result when executing a transmission request command, a reception request command, and a polling reception command described later.

If it is determined in step S804 of FIG. 8-4 that this command is the command, the latest communication result is notified to the host computer in step S850, and the normal status is sent out in step S851, and the processing ends. [Communication Interruption Command Processing] This command is for interrupting the execution of processing such as a transmission request command, a reception request command, and a polling reception request command, which will be described later.

If this command is determined in step S805, a communication interruption process is performed in step S860, and the line is disconnected. Then, in step S861, the normal status for this command is sent, and in step S862, post-processing is executed for the command whose execution has been interrupted, and the process ends. [File Information Request Command] This command is used to notify the host computer of information on the document file received by the reception request command and the polling reception request command. If this command is determined in step S806, predetermined file information is sent out in step S870, and a normal status is sent out in step S871, and the process ends. [Transmission Request Command] This command is a command for transmitting a predetermined document file to the partner terminal. still,
It is assumed that the transmission document file is stored in the facsimile in advance. In the present embodiment, there are two modes for receiving a transmission request. One is a call transmission request, and the other is a session mode transmission request. The details of each process will be described later, but a major difference is whether or not a call process is included.

If this command is determined in step S807 in FIG. 8-3, it is first determined in step S880 whether or not the call is a call transmission request. If the command is a call transmission request, call transmission processing is performed in step S881 (shown in FIG. 9). If the request is not a call transmission request in step S880, it is determined in step S882 whether there is a session mode transmission request.

If there is a session mode transmission request in step S882, session mode transmission processing (see the flowchart shown in FIG. 10) is performed in step S883.
However, in both of steps S880 and S882, if the determination is NO, the confirmation status is sent out in step S884 as error processing, and the processing ends. [Receive Request Command Processing] This command is an On-Lin
This is a command for performing reception processing in the e-mode. If it is determined in step S808 that the command is the command, a reception request process is performed in step S890, and the process ends (details will be described with reference to a flowchart shown in FIG. 11). [Polling reception request command processing] This command is a command for executing polling reception from a predetermined partner terminal. This command also roughly supports two processing modes, similar to the above-mentioned transmission request command. One is a call polling process (see FIG. 12), and the other is a session mode polling process (see FIG. 1).
3).

If this command is determined in step S809 of FIG. 8-4, it is first determined in step S900 whether the command is a calling polling request.
In step S901, a calling polling process is performed. However, if it is not a calling polling request, step S902
It is determined whether or not the request is a session mode polling request. If the result is YES, a session mode polling process is performed in step S903.

In both of steps S900 and S902, if the determination result is NO, the confirmation status is sent in step S904 as error processing.
The process ends. [Status Request Command Processing] This command is issued when a confirmation status is sent to another communication command processing, and notifies the host computer of the cause of the issuance of the confirmation status.

If this command is determined in step S810, status information is sent out in step S910, and normal status is sent out in the next step S911, and the process ends.

Step S811 indicates that a confirmation status is issued when an undefined communication command is received.

Next, the call transmission processing, the session mode transmission processing, the reception request processing, the call polling processing, and the session mode polling processing in the communication command processing shown in FIGS. 8-3 and 8-4 will be described in detail.

FIG. 9 is a detailed flowchart showing the call transmission processing. In the figure, in step S1001,
As a state of the apparatus, it is confirmed whether or not call transmission can be performed. If the communication line is busy or the like and the processing cannot be performed, a confirmation status is transmitted in step S1002 and the processing is terminated.

On the other hand, as a result of the status confirmation in step S1001, if it is determined that the call transmission is possible, in step S1003, the connection is temporarily disconnected and logically released from the connection with the host computer, and a stop command or the like is received. In a state where it can be Then, step S1004
, A call process is performed based on the address information specified by the host computer, and a connection process between the other party and the session layer is performed.

In step S1005, it is determined whether or not the connection with the other party can be normally performed. If it is determined that the connection cannot be normally performed, reselection processing is performed in step S1006 to perform logical connection with the host computer. In the following step S1007, a confirmation status is sent, and the process ends.

If it is determined in step S1005 that the connection with the other party has been established normally, the flow proceeds to step S1008.
After the connection to the session layer is completed, a process for transmitting a document specified by the host computer is performed.
If it is determined in step S1009 that the result of the document transmission process is abnormal, the process proceeds to step S1010,
If normal, the process proceeds to step S1012.

In step S1010, it is determined whether or not communication is in progress. If communication is in progress, disconnection processing is performed in step S1011 and the process proceeds to step S1006, but if communication is not in progress, the process proceeds directly to step S1006. Proceed to processing. In step S1012, a communication disconnection process is performed, and in the next step S1013, a reselection process is performed. Then, in step S1014, a normal status is transmitted, and the process ends.

FIG. 10 is a flowchart showing the session mode transmission processing. Referring to FIG.
In step 101, it is confirmed whether or not a connection to a predetermined party has been established, and if it is determined that this process cannot be continued, a confirmation status is sent in step S1102, and the process ends.

However, if the result of determination in step S1101 is that the connection has been established, step S110
At 3, the disconnect processing is performed first, and the subsequent step S
At 1104, a document transmission process is performed. If it is determined in step S1105 that the transmission process is abnormal, the flow advances to step S1106 to execute a reselection process, and in step S1107, sends a confirmation status and ends the process.

On the other hand, if the transmission processing is normal in the judgment in step S1105, reselection processing is performed in step S1108, and a normal status is sent out in step S1109, and the processing ends.

FIG. 11 is a flowchart showing the reception request processing. In the figure, it is confirmed in step S1201 whether or not the receiving process can be executed. If it is determined that the receiving process cannot be executed, the confirmation status is sent out in step S1202, and the process ends.

If it is determined that the receiving process can be executed, the flow advances to step S1203 to perform the disconnection process, and then to step S1204. In this step, the apparatus enters a reception standby state, and in the present embodiment, waits for an incoming call from any other party. Then, if there is an incoming call, it receives it and performs reception processing. Step S1205
Then, the reception result is determined, and if it is abnormal, the process proceeds to step S1206 to execute the reselection process. Then, in step S1207, the confirmation status is transmitted, and the process is terminated.

However, if the reception result is normal, the file registration processing of the document subjected to the reception processing in step S1208 is performed. If it is determined in step S1209 that the processing result is abnormal, the process proceeds to step S1206.
If normal, the process proceeds to step S1210.

In steps S1206 and S1210, a reselection process is performed. In step S1207, a confirmation status is sent, and in step S1211, a normal status is sent, and the process ends.

FIG. 12 is a flowchart showing the procedure of a calling polling process.

In step S1301 in FIG. 12A, the status in the apparatus is checked first, and if it is determined that the process cannot be continued, the check status is sent out in step S1302, and the process ends. However, if it is determined that the process can be continued, step S130
Proceed to 3 to perform disconnect processing. In the following step S1304, a calling process is performed to the destination specified by the host computer, and a connection process up to the session layer is performed. In step S1305, the processing result is determined. If the determination result is abnormal, step S131 is performed.
3 (FIG. 12-2).

If the result of the determination in step S1305 is normal, a transmission right inversion process (session inversion) is performed in step S1306, and the flow waits for a document to be sent in the next step S1307. This step S130
If the transmission of the document from the other party is started by the CDS in step 7, document reception processing is performed in step S1308. However, if the transmission right inversion processing is requested from the other party without transmitting the document, the process proceeds to step S1311 (FIG. 12B).

In step S1309, the result of the reception processing is determined. If the result is determined to be normal, the flow advances to step S1310 to execute the file registration processing of the received document. However, if the result of the determination is abnormal, the process directly proceeds to step S1311 in FIG. 12-2, where the transmission right is reversed and the transmission right is restored. Then, step S
In step 1312, the line is disconnected, and the next step S1 is executed.
After performing the reselection processing in step 313, step S13
At 14, it is determined whether a series of processing is normal or abnormal.
As a result, if the series of processing is normal, a normal status is sent in step S1315, and if abnormal,
By transmitting the confirmation status in step S1316, the process is terminated.

FIG. 13 is a flowchart showing the session mode polling reception process. Step S in FIG.
At 1401, it is confirmed whether or not the connection up to the session has been made and this processing is executed, and as a result,
If it is determined that the processing cannot be executed, step S
At 1402, the confirmation status is sent, and the process ends. However, if it is determined that the process can be executed here,
In step S1403, disconnect processing is performed, and in step S1404, transmission right inversion processing is performed.

In step S1405, the process waits for the start of document reception. If transfer of the document is started by the CDS from the partner, document reception processing is performed in step S1406, but inversion of the transmission right is immediately requested by the partner. If so, in step S1409, the process is performed thereafter.

In step S1407, the result of the document receiving process is determined, and as a result, when the receiving ends normally, the file registration process is executed in step S1408. However, in the case of an abnormal end, step S140
The process proceeds to 9. In this step S1409, a transmission right inversion process is performed, and in the next step S1410, a reselection process is performed, and in step S1411, the processing result up to that is determined.

That is, if the processing is normal, step S1
A normal status is transmitted at 412, and if abnormal, a confirmation status is transmitted at step S1413. Then, a series of processing ends.
