Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to transmission control of a plurality of original documents in a fixed-document type facsimile machine.

<Prior art> Conventionally, when document movable facsimile devices place multiple documents on a stacker and send them, they install hardware (switch, photo coupler, etc.) in the document transport path to detect the presence or absence of the next document. However, facsimile machines that fix originals remove the original after sending one original.
In this method, the original is replaced with the next original and sent again. Therefore, it is difficult to detect the presence or absence of the next document, and at present, such a switch is usually not provided.

<Problems to be Solved by the Invention> Therefore, in general, facsimile devices disconnect the line if no data is sent for a predetermined period of time, and in facsimile devices that fix originals, the line disconnects while exchanging documents. This often results in the inconvenience of having to dial multiple times when sending multiple sheets of originals.

The present invention has been made in view of the conventional drawbacks, and an object of the present invention is to provide a facsimile device that maintains a line while exchanging documents by transmitting a pseudo signal in a facsimile device that fixes a document. .

<Means for Solving the Problems> The present invention provides a facsimile device with a fixed document type, which includes a transmission key for instructing the start of transmission of a document placed on a document scanning surface, and a transmission key in response to an operation of the transmission key. , a reading means that moves in the main scanning direction to read the document; a scanner sensor that is set at a position indicating the last line of the document and generates an end signal when the reading means reaches the position;
holding means for holding the telephone circuit in response to a termination signal from the scanner sensor; measuring means for measuring the holding state of the telephone line by the holding means for a certain period of time; If the send key is operated during the hold state, the hold of the telephone line by the hold means is released and transmission of the original is started, but the send key is not operated,
When a certain period of time is measured by the measuring means,
A disconnecting means for stopping the holding of the telephone line by the holding means and disconnecting the line; and a notifying means for notifying that the next document should be placed on the document scanning surface while the telephone line is on hold by the holding means. It is characterized by having

<Function> In the document fixed type facsimile device according to the present invention, when a document is placed on the document scanning surface and the send key is operated, the reading means moves in the main scanning direction and scans the document, as in a normal facsimile device. The document is read and the read data is sent via telephone line. The operation is repeated until the last line of the document, and when the reading means reaches the position of the scanner sensor previously set at a position indicating the last line, the scanner sensor generates an end signal, and the holding means outputs the end signal. Puts the telephone line on hold upon receiving a termination signal.
If a document is placed on the document scanning surface and the send key is operated within a certain period of this pending state, transmission will be started again, but if the send key is not operated and a certain period of time has elapsed, , which stops the telephone line from being put on hold and disconnects the line. Further, the notifying means notifies the user to place the next document on the document scanning surface during the above-mentioned pending state.

<Example> Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a schematic structure of the facsimile apparatus of the present invention. Reference numeral 20 denotes a document scanning surface, which is made of a transparent plate such as glass. Reference numeral 21 denotes a document holding plate, and the surface facing the document scanning surface is a white surface. A scanner 23 that integrates a light source and a CCD reading element is arranged below the scanning surface, and is arranged in the main scanning direction, for example.
It has a reading capacity of one line of an A4 size document. This scanner 23 is provided movably in the longitudinal direction (sub-scanning direction) of an A4 size document by a transport mechanism such as a pulley 24 and a belt 25 connected to a motor. A line sensor 26 is provided at the position of the last line of the document, and when the scanner 23 reaches this position, it detects the last line and generates an end signal.

Note that the detection of the final line can also be carried out by setting in advance how many lines to read, and when the set number of lines is reached, it is determined that the line is the final line and a termination signal is generated.

FIG. 2 is a basic block diagram of the facsimile apparatus of the present invention.

In the drawings, 1 is an image reading unit, 2 is an image recording unit, 3 is an A/D converter, and 4 is an encoder/digital converter.
A decoding unit, 5 a buffer memory, 6 a transmission control unit, 7 a modem, 8 a line control unit, 9 a display unit, 10 a main control unit,
11 is a telephone; 12 is an operation unit equipped with a transmission key 30 and a notification lamp 31; 13 is a ROM;
4 is RAM.

In FIG. 2, at the time of transmission, an image signal obtained by an image reading unit 1 is digitized by an A/D converter 3, encoded by an encoding unit 4, and sequentially stored in a buffer memory 5. buffer memory 5
The encoded image data entered in the LAN is transmitted to the line via a transmission control unit 6, a modem 7, and a line control unit 8.

When all the image data lines obtained by the image reading unit have been sent out, the next original is replaced and the operation unit 12 resumes transmission. When replacing the original, the main control unit 10 executes the control operation shown in the flowchart of FIG.

That is, after the main control unit 10 detects the last line of the transmitted original, it sends out pseudo signals for a predetermined number of lines in response to the last line detection signal in order to hold the line while the original is replaced. There is. The predetermined number of lines is preset, for example, to a maximum of seven lines.

Next, the operation of the facsimile apparatus of the present invention will be explained with reference to the flowchart of FIG.

In step 1, a transmission operation is started by inputting the transmission key 30, and in steps 2, 3, and 4, one line of read data obtained from the image reading unit 1 is transmitted. In step 5, the final line sensor 26 shown in FIG. 1 determines whether the line data obtained from the image reading unit 1 is the final line data.
A judgment is made by looking at the output of , and if it is not the final line, the process returns to step 2 and data for each line is sequentially sent out. If the output of the final line sensor 26 is the final line, the process advances to step 6. After this, the CCD sensor 23 is returned to its home position, and
Turn on the notification flag (step 6). When this notification flag is turned on, the notification lamp 31 is turned on and a buzzer sound is generated.

Next, proceed to step 7 and set "7" to counter C.
is preset. In steps 8 and 9, a pseudo signal is sent out by the fill bit to hold the line, and in the meantime, in step 10, it is determined whether there is a next document. The determination in step 10 is made based on the presence or absence of a signal from the transmission key 30 for transmitting the next document, which is input to the main control unit 10 by the operation unit 12. If it is determined in step 10 that there is no input of the send key 30, the step
Proceed to step 11 to determine whether the number of lines preset in the counter has been reached. As mentioned above, the maximum number of lines preset in this counter is 7 lines, so "7" is preset in the counter C, and by checking whether the counter C value becomes 0 or not. This is to determine whether the set number of lines has been reached.

If it is determined in step 11 that the set number of lines has not been reached, the counter C is counted down by 1 in step 12, and the process proceeds to step 13. In step 13, EOL (end of line code) is sent and step 8
Return to Further, based on the detection of the last line, the notification lamp 31 is turned on and a buzzer sound is generated to prompt the operator to replace the document. The pseudo signal is sent again in steps 8 and 9, and if the transmission key is not input after that, steps 8, 9, 10, 11,
The next pseudo signal is sent in routines 12, 13, and 8, and the set number of lines is reached in step 11 (C=0).
Then, the process proceeds to step 14, where an RTC (control return signal) is sent to end the transmission, and at the same time, at step 15, the notification flag is turned off.

On the other hand, the number of steps required to reach the set line is
When it is determined that the transmission key has been input in step 10, the process proceeds to steps 16, 17, and 18, and turns off the notification flag.
At the same time as resetting the counter C, the RTC is sent out to enter the next document transmission flow, and the above operation is repeated thereafter.

In addition, steps 8, 9, and 13 are recommended by CCITT.
The total time shall be within 5 seconds. The counter 7 is the corresponding time.

Seven lines are set in the counter, but by adjusting the number of fill bits in step 9, the number of lines preset in the counter can be varied.

Further, although the above embodiment uses A4 size, it is not limited to this size.

FIG. 4 shows an embodiment of the notification means.

In the figure, 40 indicates a buzzer circuit, and a speaker 41
to generate a buzzer sound. 42 is a counter buffer, and the value of the counter C is loaded into the counter buffer 42 each time. This counter value is decoded by the decoder 43 to enable any one of the AND gates G1 to G4. The outputs of these gates are supplied to a lamp blinking circuit 44 via an OR gate G5 to control blinking of the notification lamp 31. 45 is a pulse generation circuit that generates blinking pulses for the notification lamp 31, and the generated blinking pulses are supplied to a frequency dividing circuit 46. 46,4
7 and 48 are frequency dividing circuits, respectively, and frequency dividing circuit 4
Output No. 8 generates the blinking pulse with the longest period.

Therefore, the output of the decoder 43 is the counter C
As it approaches = 0, the AND gate G1 becomes more G4.
By switching in the direction, the blinking cycle gradually becomes faster.

<Effects> As explained above, according to the present invention, in a facsimile device with a simple and inexpensive original fixed type, the line is automatically switched off for the time required to exchange the original without operating a specific switch. Not only is it possible to put the line on hold, but if the send key is not operated within a certain period of time while the line is on hold, the line will automatically stop being held and disconnect the line. Furthermore, since it notifies you to place the next document on the document scanning surface during this hold state, it is possible to improve the operability of document-fixed facsimile devices, and it is possible to use old, well-used facsimile devices. It is something that can be provided.
