The operation of the above scan service will be described below with reference to FIGS. FIG. 5 is a flowchart illustrating a command analysis process by the external I / F control unit 115 according to the present embodiment, and FIGS. 6 to 8 are flowcharts illustrating a read process according to the present embodiment. Less than,
The control when a command command for a scanner service is sent from the terminal device 200 will be described with reference to FIGS.

First, the command analysis processing by the external I / F control unit 115 in this embodiment will be described with reference to FIG.

In FIG. 3, the facsimile apparatus 100
In step S301, the external I / F control unit 115 monitors command reception from the terminal device 200. When the facsimile apparatus 100 receives the command from the terminal apparatus 200, the process proceeds to step S302, where the external I / F control unit 115 analyzes the command,
Check whether the command format is specified. If the command format is not specified, step S3
In step 03, a predetermined error process is performed. For example, a piece and a piece of NG are transmitted to the terminal device 200. Then, the command receiving process ends.

On the other hand, if the command format is the prescribed command format in step S302, the process proceeds to step S304.
Analyze the parameters of the received command. If the result of the analysis in the subsequent step S305 is that the parameters are not correct, the flow advances to step S303 to perform error processing.

On the other hand, if the parameters are correct in step S305, the flow advances to step S306 to branch to each command processing routine according to the result of the command analysis in step S302. For example, if the received command is a download request command, the process proceeds from step S306 to step S3.
In step 07, a download service operation routine is executed.

If the received command is a scan data transfer request command in step S306, the flow advances from step S306 to step S308 to execute a scan service operation routine and perform scan data transfer processing. In this way, various services according to the received command are executed.

The details of the scan data transfer process in the scan service operation routine in step S308 will be described below with reference to FIGS.

First, in the facsimile apparatus 100, FIG.
In step S311, it is confirmed whether the scanner 113 can be used. If the scanner 113 is in a usable state, the flow advances to step S313 to execute error processing and end the processing. In this error handling, for example,
In the case of a received command / parameter error, the terminal device 20
An NG response is sent to 0.

On the other hand, if the scanner 113 is operable in step S311, the flow advances to step 312 to check whether there is a document on the document table of the scanner 113 or the ADF. Scanned document is scanner 1
If it is not set to 13, operation is disabled (reading is disabled), and the process shifts to error processing in step S313 to send an NG response to the terminal device 200.

On the other hand, if the original to be read has been set in step S312, the flow advances to step S314 to send an OK response to the terminal device 200. Then, in the subsequent step 315, the scanner setting instruction command transmitted subsequently is received. Then, in step S315, analysis of the received command and parameter analysis are performed, and it is checked whether the received command is a designated command parameter. If it is not a designated command parameter, the process advances to step S313 to send an NG response to the terminal device 200.

On the other hand, if the parameter received in step S315 is the designated command parameter, the flow advances to step S316 to receive the designated command parameter (data format, resolution, main scanning reading width, sub scanning reading start position, sub scanning reading). The value is stored in the parameter storage unit of the registration unit 105 to set the parameter. Then, in a succeeding step S317, an OK response is sent to the terminal device 200.

The terminal device 20 that has received the OK response
At 0, a read data transfer command is issued as shown in FIG. Therefore, the facsimile apparatus 100 waits for receiving the read data transfer command in the subsequent step S318. If the read data transfer command has not been received within a predetermined time, the flow shifts to the selection process of step S313.

On the other hand, if a read data transfer command is received within a predetermined time in step S318, the process proceeds to step S319, where the CPU 101
The ADF control unit 113a and the image processing unit 112 that perform the document transport control 3 are activated. Thereby, the scanner 11
Reference numeral 3 controls original reading in accordance with the designated command parameters registered in the registration unit 105, and the image processing unit 112 performs necessary image processing on the read image data.

Therefore, in step S 320, the image data sequentially read by the scanner 113 is subjected to image processing by the image processing unit 112 and is sequentially stored in the reading buffer area of the storage memory 104. This storage process is, for example,
CPU by DMA (Direct Memory Access) control
The data is stored in the storage memory 104 without causing a load on the data 101.

In step S321, if reading of one page has been completed, the page end flag of the header added before the transfer image data is turned on.
Further, in this case, if there is no next page reading document, the document end flag is also turned on (ON). The reading status can be notified to the terminal device 200 by these flags. If the reading of one page has not been completed, the header flag is not turned on.

In the subsequent step S322, the external I / F control unit 115 sends out the image data stored in the storage memory 104 (image buffer) to the terminal device 200. In the next step S323, it is determined whether or not reading of one page has been completed. If the reading of one page has not been completed, the process returns to step S319, and the above processing is repeated until the reading of one page of the document / transfer to the terminal device 200 is completed, and the scan data of the document is transmitted to the terminal device 200. Forward.

On the other hand, if the reading of one page has been completed in step S323, the flow advances to step S324 to check whether there is a document to be read for the next page. If there is a document to be read for the next page, the process returns to step S315, waits for reception of a parameter for reading / transport control for the next document, and performs document reading control according to the received parameter.

On the other hand, if there is no next page reading document in step S324, the present service is terminated.

The details of document reading / transport control by controlling the scanner 113 (ADF transport controller 113a) described above will be described below with reference to FIGS.

First, in step S401 of FIG.
The sub-scanning reading start position and the number of sub-scanning reading lines specified by the scanner setting instruction command from the terminal device 200 are read from the parameter storage unit of the registration unit 105, and the start position, the number of image reading lines, and DES (Doc Egde
The number of transfer steps from the position of “Sensor” to the position of “CS (Contact Sencer)” is set in the ADF transfer controller 113a.

Subsequently, in step S402, in order to convey the leading edge of the document to the position of CS, the conveyance speed switching means (not shown) switches the motor driving of the conveyance control unit (not shown) to 400 pps (the speed for cueing). pulse / se
Set to c) (see FIGS. 2 and 4). Subsequent step S4
In step 03, the motor drive is enabled and "the drive of the transport motor is started.

The ADF transport controller 113a rotates the ADF transport roller to transport the original by setting drive data to the transport motor for a certain period of time by a timer, and is determined in advance by the transport speed in step S404. Drive data to scanner 11
3 is written to the motor control unit 113b. Then, in step S405, the sheet is conveyed between the DESs and waits until the DES is turned ON.

At step S405, D is
When ES is turned ON, the process proceeds to step S406, in which the drive data is set in the transport motor for the number of transport steps up to the position of CS, and the transport roller of the ADF is turned to transport the document. Then, in step S407, transfer to the CS position is waited for.

In step S407, the motor is driven and CS
When the document is conveyed to the position, the process proceeds to step S408, and the CS LED is read (black and white, color).
Light up according to. Subsequently, in step SS409, the ADF conveyance control unit 1
The motor drive 13a is set to 800 pps, which is the transport speed to the reading start position (800 pps drive is the fastest drive in this apparatus).

Then, in step S410, drive data is set in the transport motor. In the next step S411, motor drive is started. In step S412, it is determined whether the document has been conveyed to the reading start position. If the document has not been transported to the reading start position, the process returns to step S410, and the transport of the document is continued.

On the other hand, if the original has been conveyed to the reading start position in step S412, the flow advances to step S413, and the conveying speed switching means switches the motor driving speed according to the designated reading resolution (FIG. 2).
And FIG. 4). For example, if a resolution of 600 dpi is designated in the sub-scanning direction, the motor drive is set to 200
Perform at pps.

Following the process in step S413, the process proceeds to step S414 in FIG. 8, in which the scanner 113 drives the motor in units of one line in accordance with the accumulation timing of the image data read by the image processing unit 112 in the accumulation memory 104. Meanwhile, the image input trigger is issued to read the document image, and the image processing unit 112 performs necessary image processing on the read document image and stores it in the storage memory 104.

When the reading of one line is completed, the number of lines read is incremented by one in step S415. In the following step S416, the state of DES is monitored by the document detection means while controlling the reading of one line. Even when the number of read lines is less than the designated number of read lines, if the original has passed DES and the sensor state has been turned off, the process proceeds from step S416 to step S421, where the reading control is terminated and the sheet discharging process is performed.

On the other hand, if it is determined in step S416 that the DES is turned on by the document detecting means and that there is a reading eye light, the flow advances to step S417 to compare the number with the number of sub-scanning reading lines. If the number of read lines is less than the specified number of lines, the process advances to step S414 to perform a document reading process for the next line.

On the other hand, if the read line number is equal to the designated line number in step S417, step S41 is executed.
Proceeding to 8, the transport speed switching means of the ADF transport controller 113a sets the motor drive speed to the maximum speed of 800 pps for the motor controller 113b (FIG. 2).
And FIG. 4).

Then, in step S419, the motor control section 113b sets the drive data to the motor and drives the transport motor at the highest speed. In the following step S420, it is checked whether or not DES off (OFF) is detected by the document detecting means. If DES is not off (OFF), step S
Returning to step 419, document conveyance is continued. The document is conveyed until the DES is turned off (OFF). If the DES is turned off (OFF), the process proceeds to step S 421, where the A
The paper discharge process from the DF is performed. The above process is a process of reading one page of a document. If there is a document of a plurality of pages, the above processes of FIGS. 7 and 8 are repeated as described above.

As described above, according to the present embodiment, the reading range of the original of the facsimile apparatus 100 can be specified from the terminal device 200, and only the desired image range of the original can be read. The minimum read image data can be obtained, and the transfer data amount can be suppressed low.

Further, by controlling the document conveying means and performing the document conveyance to the document reading start position and the document conveyance after the reading range at the highest driving speed, the overall processing speed of the scan service can be increased. it can.

Let the speed be the transport speed.

As a result, in addition to the operation and effect of the first embodiment, it is possible to reduce the error of the reading start position.

It has been described that the operation is performed in the case of the scan service operation. However, the above document transport control is performed by the terminal device 20.
The transfer of data to 0 is not limited to the case of transferring data to another facsimile apparatus 400 via the communication network 300.

That is, the reading of the original image is controlled in accordance with an instruction from the terminal device 200, and the result is transferred not to the terminal device but to another designated facsimile device, for example, another facsimile device 400. ,
By reading and transferring only the portion of the document image to be transferred by facsimile, transfer of unnecessary image data can be prevented, and efficient facsimile communication can be performed.
