Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to transmission control of a plurality of originals in a fixed original type facsimile apparatus.

<Prior Art> Conventionally, in a document moving type facsimile apparatus, when a plurality of documents are placed on a stacker and transmitted, hardware (switches, photocouplers, etc.) is provided in the document conveyance path depending on the presence or absence of the next document. Although this is easily detected, the fixed document type facsimile apparatus is a method in which after transmitting one original, this original is removed, replaced with the next original, and transmitted again. Further, in the case of a fixed original type facsimile apparatus, since the facsimile apparatus does not have a buffer memory for storing data, it is necessary to connect the line after transmitting one original and preparing the next original.

<Problems to be Solved by the Invention> Therefore, since the conventional fixed original type facsimile apparatus does not have a buffer memory for storing data, the transmitted original is removed at a certain time during insertion of the original to be transmitted next. It is very inconvenient for the operator to press the transmission key each time, because the line must be connected every time, and if not, the line is cut every time one manuscript is sent. Further, it was very uneconomical to connect the line except for the purpose of transmitting data as described above.

<Means for Solving Problems> The present invention has been made for the purpose of solving the above problems, and in a fixed document type facsimile apparatus, a transmission key for instructing to start reading and transmitting a document, and A buffer memory that temporarily stores the data read from the document based on the operation of the transmission key, a transmission unit that sequentially sends the data in the buffer memory at a speed slower than the reading speed, and the end of the document when storing the data. A facsimile apparatus comprising: a detection unit for detecting a line; and an informing unit for informing a next original set based on a detection signal of the end line of the original by the detection unit.

<Operation> Since the facsimile apparatus of the present invention has a reading speed which is faster than a transmission speed and which has a buffer memory for temporarily storing the read data and further has means for sequentially sending the data from the buffer memory, By detecting the end line and notifying the next original set based on the detection signal, the time to connect the line for the purpose other than transmitting the original, which was conventionally required, becomes unnecessary, or significantly It is economical and convenient because it can be shortened.

<Example> Hereinafter, one 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 application. Reference numeral 1 denotes an original scanning surface, which is made of a transparent plate such as glass. Two
Is a document pressing plate, and the surface facing the document scanning surface is a white surface. A scanner 3 in which a light source and a CCD reading element are integrated is arranged below the scanning surface, and has a reading capacity for one line of a document corresponding to, for example, A4 size in the main scanning direction. The scanner 3 is movably provided by a transfer mechanism such as a pulley 9 and a belt 5 connected to a motor A in the longitudinal direction (sub scanning direction) of an A4 size document.
A final line sensor 6 is provided at the position of the final line of the document, and when the scanner 3 reaches this position, the final line is detected and a termination signal is generated.

It should be noted that the detection of the final line can be carried out by presetting the number of lines to be read, and when the set number of lines is reached, the final line is determined and a termination signal is generated. Reference numeral 8 is an operation unit including a transmission key for setting the number of originals, and 7 is a display unit for displaying the setting contents.

FIG. 2 is a basic block diagram of the facsimile apparatus of the present invention. In the drawing, 10 is an image reading unit, 11 is an A / D conversion unit, 12 is an encoding unit, 13 is a buffer memory,
14 is a transmission control unit, 15 is a modem, 16 is a line control unit, 17 is a telephone, 18 is an encoding unit, 19 is an image recording unit, 21 is a main control unit, 22 is an operation unit including a buzzer circuit, and 23 is a lamp. A display unit including a blinking circuit,
24 is ROM and 25 is RAM. The RAM 25 is provided with a page register for storing the set number of sheets and a counter C for counting the number of transmitted sheets.

In FIG. 2, the operation unit 22 sets the number of documents to be facsimile-transmitted. The set number of sheets is displayed on the display unit 23.

Transmission starts by inputting the transmission key. Image reading unit 10
The image signal obtained in step 1 is digitized by the A / D conversion unit 11 and coded by the coding unit 12 for sequential buffer memory.
Can be put in 13. The coded image data stored in the buffer memory 13 is sent to the line via the transmission control unit 14, the modem 15 and the line control unit 16.

When all the image data lines obtained by the image reading unit are sent out here, the buzzer circuit included in the operation unit sounds, the lamp blinks in the lamp blinking circuit included in the display unit 23, and the lamp is turned on. To resume. At the time of this document replacement, the main control unit 21 executes the control operation as shown in the flowchart of FIG.

That is, the main control unit 21 turns on the notification flag for driving the buzzer circuit included in the operation unit and the lamp blinking circuit included in the display unit after detecting the final line of the transmitted document, and requests replacement of the document. To do. When the sending of the image data stored in the buffer memory is completed, the value of the set number is subtracted by 1 and the sending is performed again.

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

In step 1, the number of sheets to be transmitted is set by the ten keys on the operation panel 8, and in step 2, the number is stored in the register. For example, the number of input sheets is 5
Let's make one. In step 3, the contents of the page register are put into the counter C, and in step 4, the display unit 7 displays the number "5" of the page register. In step 5, the transmission key included in the operation panel 8 is input to shift to the transmission sequence. Steps 6, 7,
The read data of one line obtained from the image reading unit 10 by 8 is transmitted. In step 9, it is judged whether the line data obtained from the image reading unit 10 is the final line data or not by observing the output of the final line sensor 6 shown in FIG. Send the data of. Final line sensor
When it is determined that the output of 26 is the final line, the process proceeds to step 10. After that, the CCD sensor 3 is returned to the home position and the notification flag is turned on (step 10). When this notification flag is turned on, the lamp of the display unit 7 is turned on, and the operator who causes the buzzer of the operation unit 8 to sound is instructed to replace the original. Here, in order to increase the time for replacing the original, in step 5, the image data is read in advance by inputting the transmission key and the encoded data is stored in the buffer memory 13. If it is determined in step 9 that the line is the last line, the notification flag remains ON while the code data that has not been transmitted remains in the buffer memory 13 (step 11). When the final data is transmitted in step 11, the notification flag is set in step 12.
The lamp will turn off and the buzzer will stop ringing. In step 13, 1 is subtracted from the number of sheets stored in the page register, and the subtracted value is displayed on the display unit 7 (step 14). When the value of the page register is not 0 in step 15, the process returns to step 6 and the above operation is repeated. When the value of the page register is 0, it is determined that the page is the last page, and the operation is finished.

<Effect> As described above, according to the present invention, in a fixed document type facsimile apparatus, a reading speed is faster than a transmitting speed, and a buffer memory for temporarily storing the read data is further provided, and data is read from the buffer memory. Since the means for sequentially sending the document is provided, the line is connected for the purpose other than transmitting the document which is conventionally required by detecting the end line of the document and notifying the next document set based on the detection signal. An economical and convenient facsimile apparatus can be provided because time is not required or can be greatly shortened.
