Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a facsimile broadcasting device, and more specifically, it has a variety of functions, and moreover, while one function is being used, other functions can also be performed. This paper proposes a facsimile broadcasting device that can be used.

[Prior art]

Conventional facsimile broadcasting devices are described, for example, in the article "Electrostatic G3 type facsimile and G3 type facsimile broadcasting device" published in August 1982 in the magazine "Facility", Vol. 34, No. 8, pages 133 to 140. As shown in E. et al., the image information of the read original was simply encoded, stored in a broadcast memory, and broadcasted to a plurality of recipients all at once or sequentially. However, it is desired that the facsimile machine be made multi-functional, and considering the effective use of broadcast memory, it is conceivable to provide the facsimile with the following functions. First, when looking at transmission, there is (1) Immediate storage transmission...Current broadcast communication function (2) Time-specified storage transmission...to one or multiple locations (3) Polling storage transmission, and regarding reception (4) Recording Alternative reception when paper is out (5) Inter-memory communication without fill bits (6) Received information is printed on multiple sheets, and is unrelated to communication (7) Multi-copy (many sheets are printed just by passing the original once) Make a copy).

Conventionally, there have been no devices equipped with such a wide variety of functions, and even if they are equipped with multiple functions, the capacity of the broadcast memory is relatively small at 1 to several megabytes, making it difficult to perform, for example, time-specified storage and transmission. set,
If the broadcast memory is occupied by the transmitted information, there are disadvantages such as the inability to immediately store and communicate, and the inability to perform proxy reception.

〔the purpose〕

SUMMARY OF THE INVENTION An object of the present invention is to provide a facsimile broadcasting device that can perform many of the functions described above, and can perform multiple functions simultaneously.

〔composition〕

A facsimile broadcasting device according to the present invention includes a broadcasting memory divided into a plurality of blocks, and means for independently writing and reading into each block, and has a plurality of functions that the facsimile broadcasting device has. It is characterized by being assigned.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below based on drawings showing embodiments thereof.

FIG. 1 is a block diagram showing the main parts of the apparatus of the present invention. In the figure, 1 is a broadcast memory, and memory blocks 11, 12, 13, 14, 15 are divided so that writing and reading can be done independently.
Consists of.

Each of blocks 11-15 has sufficient capacity to perform any one of the functions listed above.

The control circuit 7 is in charge of writing to and reading from the broadcast memory 1, as well as controlling the entire device related to transmission and reception.

The reading section 2 optically reads a document to be transmitted and converts it into an electrical signal. This signal is converted into encoded data by an encoding circuit 3 and is applied to a modem 9 via a multiplexer 8. , where it is modulated and (Network Control Unit) 10
is sent to the line from The encoded data is also applied to the broadcast memory 1 via the multiplexer 4 and the write/read control circuit 5, and written into a predetermined memory block.

The image information signal input through the line is sent to the NCU.
10 to the modem 9, where it is demodulated and sent to the decoding circuit 26 via the multiplexer 25, where it is decoded and printed on the printing unit 27. The encoded data demodulated by the modem 9 or is applied to the broadcast memory 1 via the multiplexer 4 and the write/read control circuit 5 and written into a predetermined memory block.

The image information data written in the broadcast memory 11 is given to the modem 9 via the write/read control circuit 5 and the multiplexer 8, where it is modulated.
It is sent to the line via the NCU 10.

The image information data written in the broadcast memory 1 is transferred to the write/read control circuit 5, multiplexers 4 and 2.
5 to the decoding circuit 26, where it is decoded and supplied to the printing unit 27 for printing.
Reference numeral 6 denotes an operation section provided with switches and the like for selecting various functions; 13 is a display section that displays the operation contents of the operation section 6 and the operation contents of the device; and 21
2 is a time memory, 22 is a telephone number memory, and 24 is a timer, all of which are used for control described below.

Next, the control contents of the control circuit 7 will be explained for each function.

(1) Immediate storage communication As shown in the flowchart in Figure 2, the original is read and scanned through the reading unit 2, and the image information encoded data is transferred to the multiplexer 4 and the write/read control circuit in write mode. 5 to broadcast memory 1 and written into block 11.

Next, when the operating unit 6 issues a transmission command with the telephone circuit (one or more) connected, the control circuit 7 sets the write/read control circuit 5 to read mode, reads out the data in the block 11, and sends it to the multiplexer. 8, send it to the line via modem 9 and NCU 10. If there are multiple destinations or the number of destinations is greater than the number of lines that can send simultaneously, change the line connection and read from memory block 11 of broadcast memory 1. Repeat the process.

(2) Time-specified storage transmission As shown in the flowchart of Fig. 3, scanning and reading image information is stored in the broadcast memory 1 in the same manner as in the case of instantaneous storage communication, but in this case, the memory block Write to 12. Then, the time to send and the telephone number of the destination are inputted from the operation unit 6, and these are stored in the time memory 21 and the telephone number memory 22, respectively.

Although the timer 24 operates independently of such control and operation, the control circuit 7 monitors the contents of the timer 24 and the contents of the time memory 21.
When the two numbers match, the contents of the telephone number memory 22 are read out and used to cause an automatic dialing circuit (not shown) to perform an automatic dialing operation. When the line is connected, the control circuit 7 changes to the write/read control circuit 5.
is set to the read mode, the contents of the memory block 12 are read out, and as in the case of instant storage communication, it is applied to the modem 9 via the multiplexer 8 for modulation, and sent from the NCU 10 to the line. If there are multiple communication destinations, the contents of the telephone number memory 22 are sequentially read out and similar control is performed.

(3) In the case of polling storage transmission As shown in the flowchart of Figure 4, (1),
The data is stored in the broadcast memory 1 in the same manner as in case (2), but in this case it is written in the memory block 13. After that, it enters an automatic call waiting state, and when there is an incoming call and a polling request is received from the other party and it is accepted, the image information is read from the memory block 13 and sent to the line as in cases (1) and (2). do.

(4) For reception Broadcast memory 1 is used for reception when there is no recording paper, when the other machine (sending side) requests inter-memory communication (for example, transmission without file bits), or when there is a print from the other machine. This applies when a communication specifying the number of copies is sent.

In this case, as shown in Figure 5, the image information data sent through the line is sent to the NCU 10.
The signal is sent to the modem 9, where it is demodulated, and written into the memory block 14 of the broadcast memory 1 via the multiplexer 4 and the write/read control circuit 5, which is set to write mode. After the communication is completed, if there is recording paper, the control circuit 7 sets the write/read control circuit 5 to read mode, reads the image information from the memory block 14, supplies it to the decoding circuit 26 via the multiplexer 25, and decodes it. The printing unit 27 is controlled to print the required number of sheets. If you do not have recording paper, copy the image information directly to memory block 1.
4, and then print when the recording paper is replenished.

(5) Multi-copy As shown in FIG. 6, the original is read and scanned and the encoded data is temporarily written into the memory block 15 of the broadcast memory 1. Next, this is read out, decoded, and printed, and the reading and printing processes are repeated until the number of prints reaches the set value.

〔effect〕

According to the present invention as described above, it is possible to realize a facsimile broadcasting device that has a large number of functions and each function can be used independently of other functions. Therefore, for example, the first user may perform time-specified storage transmission.
