DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in more detail with reference to embodiments. FIG. 1 is a block diagram showing a configuration of a facsimile apparatus according to one embodiment of the present invention. The facsimile device 15 includes an NCU 1, a modem 2, an image memory 3, a RAM 4, a ROM 5, a main control unit (CPU) 6, a display unit 7, an operation unit 8, a reading unit 9, and a recording unit. 10 and PC interface 11
And

The NCU 1 has a function of controlling connection with the telephone line 13 and detecting transmission and reception of a telephone number (corresponding dial signal) of the other party. The modem 2 conforms to the ITU-T Recommendation T.30. 30 based on a facsimile transmission control procedure according to V.30. 17, V.I. 27
ter. Modulation and demodulation of transmission / reception data according to 29 or the like are performed. The modem 2 also has a V23 demodulation function to receive the number display information. The image memory 3 temporarily stores received image data and original image data read by the reading unit 9. ROM5 is
A program for controlling the entire facsimile machine is stored.

The main control section 6 is constituted by a CPU and has a ROM
In accordance with the program stored in the control unit 5, each unit constituting the facsimile apparatus is controlled. The display unit 7 displays various information such as the operation state of the facsimile machine. The operation unit 8 includes ten keys, a start key, and other keys. The reading unit 9 reads image data on a document and outputs black and white binary image data. The reading unit 9 is mechanically provided with the line sensor shown in FIG. 5, a feed mechanism of the line sensor, a roller for feeding a document, a drive motor, and the like, and has the functions of an ADF and an FBS.
The recording unit 10 includes an electrophotographic printer, and records received image data and image data of a document read by the reading unit 9 in a copy operation on a recording sheet. In FIG. 5, the ADF has a line sensor 31 for reading arranged at a predetermined position, and the document 32 is moved by rollers 33 and 34 so as to pass through the position of the line sensor 31 for reading. Is placed on a flat glass plate 35, and the line sensor 31 is moved to read.

The PC interface 11 is connected to a personal computer (PC) 20 as an external information processing terminal, and exchanges data with the PC 20 via the PC.

A novel feature of the facsimile apparatus of this embodiment resides in a function achieved by processing executed by the main control unit 6 according to a system program stored in the ROM 5.

FIG. 2 is a block diagram showing the configuration of the PC 20. The PC 20 includes a main control unit 21, a display unit 22,
It includes a keyboard 23, a printer 24, an external medium reading unit 25, a disk 26, a memory 27, an interface 28, and a bus 29. However, these hardware configurations are also generally well-known. The PC 20 is connected to the PC interface 11 via an interface 28.

Next, an image reading processing operation in the system of this embodiment will be described with reference to flowcharts shown in FIGS.

In the facsimile apparatus 15, first, in step ST1, the image scan image is stored in the image memory 3.
Clear from. Next, the process proceeds to step ST2. In step ST2, it is determined whether a scan command has been received from the external PC 20. If a scan command has not been received, the process waits until a scan command is received. On the other hand, when a scan command is received, the process proceeds to step ST3.

In step ST3, it is determined whether or not there is a document in the ADF section. If there is a manuscript, step ST
Move to 4. On the other hand, if there is no original, the process proceeds to step ST8. In step ST4, the original is read by the ADF unit, encoded, and additionally stored in the image memory 3.
Then, the process proceeds to step ST5. In step ST5, PC2 is notified that reading by the ADF has been completed.
Notify 0. Next, the process proceeds to step ST6.

In step ST8, the PC 20 is notified that there is no original in the ADF. Then, the process proceeds to step ST9. In step ST9, although not shown in FIG. 3, a timer is started when a scan command is received from the PC 20, and it is determined whether or not the timer has timed out. If the time has not elapsed, the process returns to step ST3, and it is checked whether or not the ADF has a document until the time has elapsed. On the other hand, if the time is up, the process proceeds to step ST10.

In step ST6, it is determined whether or not a designation of document reading has been received. If the designation that the next original is to be read has been received, step ST
Return to 2. On the other hand, if not received, step ST7
Move to. In step ST7, the image memory 3
Is sent to the PC 20 and the process is terminated.

In step ST10, it is determined whether a scanned image exists in the image memory 3. If there is a scan image, the document has been read by the FBS, and the process proceeds to step ST7, where the scan image in the image memory 3 is sent to the PC 20 as described above. Then, the process ends. In step ST10, when there is no scanned image, it means that there is no reading of the FBS, and the process ends.

Next, the processing of the PC 20 will be described.
First, in step ST11, reading is performed using the ADF.
Or FBS. Next, in step ST12, after reading, a setting is made as to whether to read the next document. Subsequently, the process proceeds to step ST3.

In step ST13, it is determined whether or not a start icon has been designated. If the start icon is not specified, the process waits at this step until the start icon is specified.
On the other hand, when the start icon is designated, step ST
Move to 14. In step ST14, a scan command (including the designation of a reading unit and the designation of the presence / absence of the next document) is transmitted to the facsimile machine 15. Subsequently, the process proceeds to step ST15.

In step ST15, it is determined whether or not there is a read end notification. If the end notification has not been received from the facsimile machine 15, the process stands by at this step ST until it is received. On the other hand, if the end notification arrives, step S
Move to T16. In step ST16, the completion of reading is displayed on the display unit. Then, step ST1
Move to 7.

In step ST17, it is determined whether or not the presence of the next original is displayed. If it has been set in step ST12, the process proceeds to step ST19. If not, the process proceeds to step ST18. In step ST19, the operator sets the document on the reading section of the facsimile machine, and returns to step ST11. In step ST18, the image data is received from the facsimile machine, stored in the memory, displayed on the display unit, and the process ends.
