Abstract

PURPOSE:To improve operability by enabling the transmission of plural sheets of originals to be performed continuously without disconnecting a line, by holding the line by sending a pseudo signal during the exchange of the original. CONSTITUTION:A transmission operation is started by inputting a transmission key 20, and read data of one line obtained by an image reading unit 1 is sent. And when it is decided that a line is not the final line by observing the output of a scanner sensor 35, the data at every line is sent in order. When the output of the sensor 35 shows the final line, the pseudo signal is sent by a filled bit, then, the line is held, and the presence of the next original is judged. The above judgement is performed by the presence/absence of the signal of the transmission key 20 for the transmission of the next original fetched in a main control unit 10. When no key 20 is inputted, the exchange of the original is urged. When the input of the key is judged until the pseudo signal arrives at a set line, the transmission of the next original is performed. Such operation is repeated.

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. However, 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 general, facsimile machines disconnect the line if transmission data is not sent for a predetermined period of time, and in facsimile IJ devices that fix originals, the line disconnects while exchanging originals. This caused an additional inconvenience when it was necessary to dial multiple times when sending multiple documents.

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 the line during document exchange by transmitting a pseudo signal. do.

<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, and a pseudo signal generation means for holding the line in response to the detection of the end line of the document by the detection means, and transmitting the pseudo signal from the pseudo signal generation means. This feature is characterized in that the line is held while the document is being exchanged.

<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 is read line by line, encoded, and then the data is sent out. These operations are repeated until the final line of the document is reached.
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 documents are exchanged, and when the line is on hold, the next document is set and the send key is operated to send image data again. .

Therefore, in a facsimile machine that has a simple and inexpensive original fixed type, it is possible to hold the line for the time required for exchanging originals by sending a pseudo signal, so that it is possible to send multiple originals in succession. can be sent.

<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. 30
is the document scanning surface, which is made of a transparent plate such as glass.

Reference numeral 31 denotes a document holding plate, and the surface facing the document scanning surface is a white surface. Scanners 3 and 2 that integrate a light source and a CCD reading element are arranged below the scanning surface, and have a reading capacity of one line of an A4-sized document in the main scanning direction.

It is equipped with This scanner 32 has a pulley 3 connected to a motor in the longitudinal direction (sub-scanning direction) of an A4 size document.
4 and a bell 833, etc., so as to be movable. Scanner sensor 3 is located at the last line of the document.
5 is provided, and when the scanner 32 reaches this position, it detects the last 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 encoding/decoding unit, 5 is a buffer memory, and 6 is a transmission ft1lJ (fN)
7 is a modem, 8 is a line control unit, 9 is a display unit, and 10 is a main control unit.

11 is a telephone, 12 is a transmission key 20 and a notification lamp 21
13 is a ROM, and 14 is a 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. The encoded image data stored in the buffer memory 5 is transmitted to a 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 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 the flowchart of FIG.

That is, after detecting the last line of the transmitted document, the main control unit 10 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 document is replaced. ing. 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.

Starting from step (2), a transmission operation is entered by inputting the transmission key 20 in step (2), and one line of read data obtained from the image reading unit 1 is sent out in steps (2), (2), and (2). In step (2), 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 scanner sensor 35 shown in FIG.
Sends data for each line. If the output of the scanner sensor 35 is the final line, proceed to step (2).

In steps (2) and (2), the fill pit sends out a pseudo signal to put the line on hold, and in the meantime, in step (2), it is determined whether there is a next document.

The determination in step (2) is made based on the presence or absence of a signal from the transmission key 20 which is input to the main control unit 10 by the operation unit 12 and which indicates that the next original document cannot be transmitted.

If it is determined in step (2) that no transmission key has been input, the process proceeds to step (2), where it is determined 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 17'' is preset in the counter C, and by checking whether or not the counter C value becomes 0, the set line number is This is to judge whether the number has been reached.

If the set number of lines has not been reached in step (2), the counter C is counted down by 1 in step [phase], and the process proceeds to step (2). At step @, t'1EOL (line end code) is sent and the process returns to step (2). Further, based on the detection of the last line, the display unit 9 prompts the operator to replace the document. Step again ■,■
A pseudo signal is sent by , and if there is no input of the transmit key after that, pseudo signals are sent sequentially in the routine of steps ■, ■, ■, ■, [phase], @, ■, and the set number of lines is reached at step ■ (C =O), proceed to step 0 and RTC(
A control return signal) is sent to end the transmission.

On the other hand, if it is determined that the send key has been input in step ① before reaching the setting line, the process proceeds to step 0 and R
The TC is sent out, the next document transmission flow starts, and the above operation is repeated thereafter.

In addition, according to the recommendation of CCITT, the total time of steps ①, ②, and ② should be within 5 seconds. The counter 7 is the corresponding time.

Although a line is set in the counter, the number of lines preset in the up counter is varied by adjusting the number of fill pits in step (2).

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

<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
