Accordingly, plural sheets of originals can be sent continuously.

Description

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

<Prior art> Conventionally, when document movable facsimile machines place multiple documents on a stacker and send them, hardware (switches, photo couplers, etc.) is installed in the document transport path to detect the presence or absence of the next document. Although it is easily detected by this, facsimile machines with fixed originals are of a type that, after transmitting one original, removes the original, replaces it with the next original, and sends it again. Therefore, it is difficult to detect the presence or absence of the next document, and the current situation is that such a switch is usually not provided.

<Problems to be Solved by the Invention> Therefore, in facsimile machines, the line is generally disconnected if no transmission data is sent for a predetermined period of time, and in facsimile machines with fixed originals, the line is disconnected while the original is being exchanged. This often causes the inconvenience of having to dial multiple times when transmitting 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 in which a document is fixed, and which maintains a line during document exchange by transmitting a pseudo signal. .

<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 that instructs to start transmission of a document placed on a document scanning surface, and a detection means for detecting the end line of the document; a pseudo signal generating means for holding the line in response to the detection of the end line of the document by the detection means; and a detection signal for detecting the end line of the document by the detection means. The present invention is characterized in that a notification means is provided for notifying the next set of manuscripts based on the above-mentioned information, and a line is maintained during the manuscript exchange by transmitting a carrier signal from the pseudo signal generating means.

<Operation> In the facsimile apparatus of the present invention, first, a document is set, and the send key is operated to instruct the start of transmission.

Next, like a normal facsimile machine, the image of one surface is read line by line, encoded, and then the data is sent out.

These operations are repeated until the last line of the document is detected, and when the last line is detected by the detection means, a pseudo signal from the pseudo signal generation means is used to hold the line while the document is exchanged, and also drives the notification means to set the next document. Notify. When the operator sets the next original while the line is on hold and presses the send key, the image data is sent again.

Therefore, in a facsimile machine with a fixed original type that is simple in structure and inexpensive, it is possible to hold the line for the time required for exchanging originals by sending a pseudo signal, making it possible to send multiple originals in succession. Can be done.

<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. 20
is the 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 disposed below the scanning surface, and has a reading capacity for one line of an A4 size document in the main scanning direction. This scanner 23 is provided movably in the longitudinal direction (sub-scanning direction) of an A4f size document by a transport mechanism such as a pulley 24 and a bell seat 25 connected to a tC motor. A final line sensor 26 is provided at the position of the final line of the document, and a scanner 23 is installed at this position.
When the line reaches the final line, it detects the final line and generates a termination signal.

Note that the detection of the final line can also be carried out by setting in advance how many lines are to be 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, 4 is an R conversion-decoding unit, 5 is a buffer memory, 6 is a transmission control unit, and 7
is a modem, 8 is a line control unit, 9 is a display unit,
10 is a main control unit.

11 is a telephone, 12 is a transmission key 30 and a notification lamp 31
13 is a ROM, ], 4 is R, A
It is M.

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

When all the image data lines obtained by the image reading unit are sent out, the next original is replaced by the operation unit 1.
2 restarts transmission. When replacing the original, the main control unit 10 executes a control operation as shown in flowchart 1- of FIG.

That is, after the main control unit 10 detects the last line of the original to be transmitted, 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, the transmission operation is started by pressing the transmission key 300 Å, and in step 2.3.4, one line of read data obtained from the image reading unit 1 is sent out. In step 5, it is determined whether the line data obtained from the image reading unit 1 is the final line data by looking at the output of the final line sensor 26 shown in FIG. If the output of the final line sensor 26 is the final line, proceed to step 6.After this, the CCD sensor 23 is returned to its home position, and the notification flag is set to O.
N (step 6). When this notification flag is turned on, the notification lamp 31 is lit and a buzzer sound is generated.

Next, the process advances to step 7, and the counter C is preset to 7''.In steps 8 and 9, a pseudo signal is sent by the fill bit to hold the line, and in the meantime, in step 10, whether there is a next document or not 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. In step 10, there is no input from the transmission key 30. If it is determined that this is the case, the process proceeds to step 11, where it is determined whether the number of lines preset in the counter has been reached.The number of lines preset in the counter with 8 is the maximum of 7 lines as described above.
Therefore, "7" is added to the counter C, and by checking whether the counter C value becomes 0, it is determined 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 (
The line termination code) is sent and the process returns to step 8. Also,
Based on the detection of the final line, the operator is prompted to replace the document by lighting the notification lamp 310 and generating a buzzer sound.

The pseudo signal is sent again through steps 8 and 9, and if the transmission key is not input after that, steps 8 and 9゜10, ]
, ], , 12, 13, and 8 are sequentially sent pseudo signals, and when the set number of lines is reached in step 11 (C=0), the process proceeds to step 14, where an RTC (control return signal) is sent and the transmission ends. and step 15
Turn off the notification flag at .

On the other hand, if it is determined that the transmit key has been input using the steering knob 10 before reaching the setting line, step 16;
Proceed to step 1.7.18, turn off the notification flag, reset the counter C, send out the RTC, enter the next document transmission flow, and repeat the operations described in 2.

In addition, steps 8 and 9゜13-1 are recommended by CCITT.
- The running 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 pits in step 9, the number of lines preset in the counter can be varied.

Furthermore, although the second 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, which drives the speaker 4 to generate a buzzer sound. 42 is a counter buffer, and the value of counter C is loaded into the counter buffer 42 each time. This counter value is decoded by the decoder 43 to enable one of the AND gates G1 to G4.

The outputs of these gates are supplied to a lamp blinking circuit 4.4F via an OR gate G5 to control blinking of the notification lamp 31. 45 is a pulse generation circuit that generates a blinking signal for the notification lamp 31, and the generated blinking signal is supplied to a frequency dividing circuit 46. 46, 47, and 48 are frequency divider circuits, and the output of the frequency divider circuit 48 generates blinking pulses of the highest frequency.

Therefore, as the output of the decoder 43 approaches the counter C-0, the AND gate G1 switches in the G4 direction, so that the blinking cycle gradually becomes faster.

<Effects> As described above, the present invention provides a facsimile device with a fixed original, which includes a transmission key for instructing the start of transmission of the original placed on the original scanning surface, and a transmission key for instructing the start of transmission of the original placed on the original scanning surface, and detection means for detecting the terminal line of the
pseudo signal generating means for holding the line in response to the detection of the end line of the original by the detection means; and detection of the end line of the original by the detection means (notification of the next set of originals based on No. 3); The facsimile apparatus is characterized in that the line is maintained during document exchange by transmitting a pseudo signal from the pseudo signal generating means.
