[0042]
Hereinafter, the image data processing and the flow of image data in the fax mode of the facsimile apparatus F configured as described above will be described in more detail.
(Fax mode)
The fax mode includes processing for sending a document to a destination and receiving a document from the destination.
[0043]
First, transmission of a document to the other party will be described. Transmission documents set at predetermined positions on the document tray 30 are sequentially supplied one by one onto the document table 1 of the scanner unit A, sequentially read, and 8-bit. The document image data is transferred to the main image processing board 400. The 8-bit document image data transferred to the main image processing board 400 is subjected to predetermined processing in the multi-value image processing unit 402 as 8-bit document image data.
[0044]
The 8-bit document image data is then sent from the connector 405 on the main image processing board 400 side to the sub image processing board 500 side via the connector 505 on the sub image processing board 500 side, and a binary image processing unit. A multi-value / binary conversion unit 501a 501 converts 8-bit document image data into 2-bit document image data together with processing such as error diffusion.
[0045]
The reason why 8-bit document image data is converted into 2-bit document image data including processing such as error diffusion is that there is a problem in image quality just by performing multi-value binary conversion. This is because consideration is given to reducing deterioration in image quality. The document image data converted into a binary image in this way is compressed in a predetermined format and stored in the memory 502a.
[0046]
Then, when the transmission procedure with the other party is performed and the transmission possible state is ensured, the document image data read from the memory 502a is transferred to the FAX board 603 side, and is compressed on the fax board 603. Necessary processing such as change is performed, and the data is sequentially transmitted to the other party via the communication line.
[0047]
Next, the processing of the original image transmitted from the other party will be described. When the original image data is transmitted from the other party via the communication line, the FAX board 603 performs a predetermined communication procedure and is transmitted. Receive incoming document image data. Thereafter, the document image data compressed into a predetermined format is sent to the binary image processing unit 501 from a fax interface provided in the binary image processing unit 501 of the sub image processing board 500. In the binary image processing unit 501, the original image data transmitted as the original image data is reproduced on a page basis by the compression / decompression processing unit 501b or the like.
[0048]
Then, the document image data reproduced as an image in page units is transferred to the main image processing board 400 side and subjected to gamma correction. Subsequently, the laser control 404 controls writing of an image in the LSU 10, and the image is reproduced in the LSU 10.
[0049]
FIG. 3 is a front view of the operation panel 103. The operation panel 103 is configured by arranging various operation key groups 105 around the LCD 104. Of the operation key group 105, each operation mode of copy, printer, and fax can be selected by the operation keys 105a, 105b, and 105c.
[0050]
The operation key 105d is a key that is selected when the scanner unit A is used as a single scanner such as a personal computer, and the Select key 105e is operated at various function selections and operation points described later. The operation key 105f is a key for instructing the start of the operation, the numeric key 105g is a key for inputting the number of copies, the telephone number, and the like, and the operation key 105h is a facsimile transmission registered in advance. It is a key to call the other party.
[0051]
FIG. 4A is a flowchart for explaining the operation of the fax apparatus F in the fax mode, and FIG. 4B is a diagram showing a display screen of the LCD 104 corresponding thereto.
[0052]
First, when the telephone number of the transmission destination is input from the operation key 105h or the numeric key 105g (S1), the telephone number of the transmission destination is displayed on the LCD 104 (display screen 5a). When an operation start is instructed from the operation key 105f (S2), it is determined by the switch SW whether or not a document is set on the document tray 30 side, that is, the automatic document feeder (hereinafter referred to as “SPF”) side. (S3).
[0053]
If the document is set as a result of the determination (YES in S3), the document is automatically fed and read (S4), and transmission is started (S5). At this time, the telephone number of the transmission destination is displayed on the LCD 104 (display screen 5f). When transmission ends (S6), the operation ends.
[0054]
On the other hand, if the document is not set on the SPF side (determined as NO in S3), the user of the facsimile machine F is confirmed whether or not the user forgot to set the document on the SPF side (S7). ). The confirmation method is to display a warning message indicating that no original is set on the SPF side on the display screen of the LCD 104 (display screen 5b).
[0055]
If the user forgets to set the document on the SPF side (YES in S7), the document is set on the SPF side (S8). As a result, the original set on the SPF side is read (S4), and the original image is transmitted (S5, S6). On the other hand, if the original is not set even after a predetermined time has elapsed (S7), it is determined that transmission by the original fixed reading device (hereinafter referred to as “OC”) is selected, and the process proceeds to the OC side (S11). To S14).
[0056]
When the OC-side process is started, a confirmation message for confirming to the user of the facsimile apparatus F that the OC-side process is started is displayed on the LCD 104 (display screen 5c). In response to this, a document is set on the document table 1 by the user (S11), and further, when the Select key 105e is depressed (S12), reading of the set document is started (S13). At this time, the reading status is displayed on the LCD 104 (display screen 5d).
[0057]
Thereafter, a message for confirming the presence or absence of a further transmission original is displayed on the LCD 104 (display screen 5e), and the presence or absence of a further transmission original is determined (S14). If there is a further transmission document by the operation of the user's Select key 105e or the operation key 105f for this display (YES in S14), the document is set again on the document table 1 (S11), and a further transmission document is received. If not (NO in S14), transmission is started (S5). At the start of transmission, the telephone number of the transmission destination is displayed on the LCD 104 (display screen 5f).
[0058]
In this way, since the SPF side and the OC side are automatically switched and used based on whether or not a document is set on the SPF side, it is not necessary to switch them during transmission, improving operability. And the changeover switch can be omitted.
[0059]
Since many facsimile machines use SPF, there is a high possibility that the user forgets to set the original when the original is not set on SPF. Therefore, it is possible to prevent unnecessarily switching to the OC side reading.
[0060]
In addition, although confirmation operation increases at the time of use of OC with low use frequency, since the use frequency of OC is low normally, operativity does not fall remarkably.
[0061]
FIG. 5A is a flowchart showing another operation example of the present invention in the fax mode, and FIG. 5B is a diagram showing a display screen of the LCD 104 during the operation. In the operation process shown in FIG. 5 (a), there is an operation process common to the operation process shown in FIG. 4 (a), and therefore, the common operation process is given the same step number. Is omitted. Further, since a predetermined display is made on the LCD 104 in the same operation process, the display screen of FIG. 4B and the display screen of FIG. 5B displayed on the LCD 104 in the same operation process are the same. The description will be simplified by attaching the reference numeral.
[0062]
The feature of this operation is the operation after S7. When no document is set on the SPF side, the user of the facsimile apparatus F is confirmed whether or not he forgot to set the document on the SPF side in S7. Warning message is displayed (display screen 5b).
[0063]
Here, if the user has not forgotten to set the document on the SPF side (NO in S7), the Select key 105e is depressed (S21). Accordingly, the selection message for causing the user of the facsimile apparatus F to select either the transmission of the original image from the OC side or the communication by polling reception by the operation of the operation key 105f is displayed on the LCD 104. Is displayed (S22: display screen 7g).
[0064]
When transmission of the document image from the OC side is selected, the document image is transmitted from the OC side by setting the document on the document table 1 (S11). On the other hand, when communication by polling reception is selected in S22, communication by polling reception is started (S23), and when communication by polling reception ends (S24), the process is terminated.
[0065]
In this way, the LCD 104 displays a selection message for selecting either communication by polling reception or transmission by OC, together with a warning message that a document is not set on the SPF side. When no original is set on the side, polling reception without a transmission original can be selected.
[0066]
【The invention's effect】
According to the present invention, an image of a document such as a book set on a document table is scanned together with a document feeding type image reading unit that automatically feeds a sheet-like document and sequentially reads the document image. A document fixing type image reading unit adapted to read, and automatically feeding a document type image reading unit and a document fixing type image reading unit depending on whether or not a document is set in an automatic document feeder Are used by switching between and. With such a configuration, the operability can be improved because a switching operation is unnecessary during transmission. Furthermore, the changeover switch can be omitted.
[0067]
In addition, since the conventional facsimile apparatus uses a document feeding type image reading means, if there is no document set in the automatic document feeder, there is a high possibility of forgetting to set the document. According to the invention, when a document is not set in the automatic document feeder, a warning message indicating that a document is not set is displayed, and a transmission mode by the document fixed image reading means is selected. It is configured to display a confirmation message to confirm that. Thus, it is possible to prevent automatic switching to the document fixing type image reading means. On the other hand, when using a document fixing type image reading means with low frequency of use, the number of confirmation operations increases. However, since the frequency of use is low, the operability is not significantly reduced.
[0068]
According to the present invention, when a document is not set in the automatic document feeder, the message display means transmits either a warning message, communication by polling reception, or transmission by the document fixed image reading means to the facsimile. A selection message for causing the device user to select is displayed. Accordingly, it is possible to cope with polling reception without a transmission original although a call is made.
