Abstract

PURPOSE:To deliver a call signal from a call signal generating means based on the output information of a storage means by selecting either one of transmitting address selection buttons and at the same time to select a transmitting system for a control means on the basis of the output information of the storage means. CONSTITUTION:A transmitting original is set to a facsimile (FAX) transmitter, and either one of transmitting address selection buttons 33'-44' is pushed. Then a coding circuit 50 designates the initial value corresponding to the desired transmitting address to an address counter 52 with an output signal (b) and at the same time informs that the selection button is pushed to a control circuit 8 by means of an output signal (c). Thus the circuit 8 makes an FAX transmitter prepare for transmission. Then storage circuits 55 and 57 are set in a reading mode respectively by a signal (a), and the numerical information of the call number of the transmitting address is read by a digit out of the circuit 57. Then a dial pulse signal is transmitted to the receiver side via a dial pulse generating circuit 7 and then through a transmission line, and at the same time the contents of the transmission are displayed at a display 4. While the information on the device type of the transmitting destination is delivered to the circuit 8 from the circuit 55 to decide a transmitting system.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a data transmission device VC that performs data transmission with many types of communication equipment.

There are a wide variety of data transmission methods in current data transmission formats. Taking facsimile transmission as an example of data transmission, the modulation methods that are one set of transmission methods include AM (amplitude modulation), AM-PM (amplitude-phase modulation),
There are M (frequency modulation) method, QAM (quadrature amplitude modulation) method, etc. In addition, the MH (Modify Huffman) system and MR (Modify Read) are other elements of the transmission system and are recommended by the CCITT (International Telegraph and Telephone Consultative Committee) as encoding systems for band compression. There are two types of encoding methods, and each manufacturer has a variety of encoding methods. Furthermore, as a method unique to facsimile transmission, there is a scanning method that skips all-white lines and all-white blocks.

By appropriately combining the modulation method, encoding method, and scanning method as described above, a large number of transmission methods can be realized. In facsimile transmission, one of these many transmission methods is used, and the selection is made by exchanging communication control signals between the sender and the receiver immediately before data transmission. l! There are methods such as identifying the species and determining the most suitable transmission method, or determining the transmission method by the operator on the transmitting side selectively selecting a receiver model selection button provided on the transmitter. .

However, since the transmission method is determined by the mitter using the tar, communication control signal, the range of transmission methods is actually limited, and it takes time to decide on the transmission method, so the usage efficiency of the transmission line is reduced. The disadvantage is that it deteriorates. Also,
The latter method has the disadvantage that it is necessary to check the recipient's model each time a transmission is made, and communication failures due to operational errors are likely to occur.

As a preliminary work, the calling number and destination model number of the predetermined destination are stored in each storage section of the facsimile transmitter. 6, 6. That is, when storing the call number, while pressing the call number storage button 31 with your finger, press one of the destination selection buttons 33 to 44, and then Press the number selection buttons 21 to 3o in sequence according to the destination call number.Also, when storing the destination model number, press the destination selection buttons 33 to 44 while pressing the destination model number storage button 32 with your finger. Press one of the predetermined buttons, and then press the number selection buttons 21 to 3 according to the destination model number.
Press o.

The calling number and destination model number can be stored by the above operations, and the operation of the facsimile transmitting apparatus 1 at this time will be described below.

First, when the call number storage button 31 is pressed during call number storage, the output signal a of the switch 31' becomes low level (hereinafter abbreviated as L"). This output signal a is transmitted to the control circuit. 8, the control circuit 8 can know that the calling number is being stored, and stops the operations of the parts other than the calling number storage section 6 and destination model number storage section 6. At the same time, the output signal a is input to the write enable terminal (hereinafter abbreviated as WE terminal) of the memory circuit 67 and the switch 56, so the switch 66 selects the output of the AND circuit 51, which is opposite to that in FIG. Note that before the number selection buttons 21 to 30 are pressed, all input signals of the AND circuit 51 are at high level (hereinafter referred to as
Abbreviated as nH++. ), the AND circuit 61
The output signal of the switch 56 is input to the chip select terminal (abbreviated as S, F, C8 terminal) of the memory circuit 67. Since the memory circuit 6γ functions according to the memory circuit function table shown in Table 2, the memory circuit 6γ does not operate at this time.

(This indicates 'H'-i or +L+') Next, while the call number storage button 31 is pressed, press the destination selection buttons 33 to 44. When one of the chairs, for example 33, is pressed, the output signal of the switch 33' becomes 'L'', which causes the encoding circuit 50 to turn on the switch 31' (corresponding to /C) by the first output signal. A predetermined value is output as the initial value of the address counter 62, and a second output signal c f
The output signal d of the address counter 62 also changes, and the address of the memory circuit 67 is set. In the initial state, the output signal d of the address counter 52 is changed from "H" to "L°". When the bit is o'', that is, N L ++, and the initial value is set by the encoding circuit 6°, ``1pa'' or ``Hpa'' always appears in one of the bits.

Furthermore, while the call number storage button 31 is kept pressed, the number selection buttons 21 to 21 are pressed according to the predetermined call number.
3o, for example, the button 3o, the output signal of the switch 30' corresponding to the button 3o becomes "L". As a result, the output signal of the AND circuit 51 becomes "L", so the memory circuit The signal input to the C3 terminal of the switch 57 also becomes "L", and the storage circuit 57 enters a write state, and the data is stored at a predetermined address in the entire data storage circuit 67 formed by the output signals of the switches 21' to 30' at this time. And button 3
When the finger is removed from 0, the calling number and destination model number are stored in the calling number storage section 6 and the destination model number storage section 6 of the transmitting device 1, respectively.

Furthermore, the operation when actual transmission is performed based on this will be explained below.

First, a transmission document is set at a document setting position (not shown) of the facsimile transmitter 1, and one of the desired destination selection buttons 33 to 44 is pressed. The encoding circuit 50 sends an output signal b4 to specify the initial value corresponding to the destination in the address counter 62, and at the same time, the output signal C selects one of the destination selection buttons 33 to 44. Notifies the control circuit 8 that the button has been pressed. In response to this, the control circuit 8 causes the facsimile transmitter to prepare for transmission. On the other hand, signal B4 manually operated address counter 52,
Since at least one bit of the signal d outputting the signal d to the NOR circuit 53 and the memory circuits 55 and 57 is 'H2, the output of the NOR circuit 63 is "L..." at this point.
becomes.

On the other hand, since both the memory buttons 31 and 32 are not pressed, the output signals of the switches 31' and 32' are both V and H, and the switches 54 and 56 both select the output of the N0R1 path 63. . Therefore, the input signals of the C3 terminals of the memory circuits 55 and 57 are both "L'", and the input terminals of the WE terminals are both "H++", so the memory circuits 56 and 67 are operated as shown in the memory circuit function table in Table 2. Starts reading the specified contents of the address specified in .

The first digit information of the calling number of the destination is outputted from the memory circuit 57 to the dial pulse generating circuit 7 and the display section 4 without being changed. Then, the display unit 4 displays the numerical information at the left end of the telephone number section of the display device 2° on the operation panel 2. 1, the dial pulse generating circuit 7 outputs a number of dial pulse signals corresponding to the numerical information of the dial pulse signal, and when it is finished, the output signal f is used to request the next numerical information total control circuit 8. The control circuit 8 inputs one pulse signal qf to the address counter 62 in accordance with this request, calculates '1' (ijJI) to the output value of the address counter 52, and stores the second calling number information from the memory circuit 57. The address is changed so that the address is read out.The following operation is repeated, and dial pulse signals are output from the dial pulse generation circuit 7 for all the calling numbers corresponding to the destination.These dial pulse signals are transmitted to the network. Control circuit 9
It is sent to the transmission line 19 via an exchange (not shown) e(
Therefore, a transmission path is established with the receiving station.

On the other hand, the storage circuit 55 outputs numerical information of the model number of the destination to the control circuit 8. fljllf[l]
The circuit 8 switches the computer-programmed transmission control procedure according to the input numerical information of the destination model number, and also instructs the transmission control circuit 11 about the modulation method and encoding method. That is, the transmission control circuit 11 selects any one of the modulation circuits 16 and any one of the encoding circuits 16 by switching the switches 14 and 17 at -9 according to instructions from the control circuit 8. For example, if the destination model number is -F, 12. If,
The transmission control circuit 11 uses the switch 14 to perform MH encoding [
The QAM circuit 16a is selected by the switch 17, and the QAM circuit 16di is selected by the switch 17.

The transmission method is determined through the above series of operations, and when the identification signal sent from the receiving station is heard from the monitor speaker 58 when the transmission path is established, the Noakunmiri button 4
Pressing 6 starts facsimile communication.

In this case, since the fan/millimeter transmitter 1 knows the model of the receiving station in advance, it selects and sends out a communication control signal that is compatible with the model of the receiving station, thereby controlling the transmission control procedure between transmitter and receiver. There will be no loss of time for the child. Note that the operation during facsimile communication is the same as the conventional one, so a description thereof will be omitted.

Although the above explanation has been limited to facsimile/millimeter communication, the present invention is not limited thereto, and can generally be applied to data transmission devices in a wide sense. For example, as long as the data transmission device is equipped with an appropriate transmission function, the present invention can be applied even if the terminal device at the receiving station is a printer, telex, computer, word processor, etc. by increasing the destination model number. Furthermore, if a plurality of transmission lines are connected in parallel to the data transmission device, it is also possible to switch the transmission lines according to the destination model number.

An example of this is a data transmission device that combines a wired facsimile and a wireless facsimile.

In this embodiment, the determining factors of transmission conditions are limited to modulation and coding method, but it is obvious from the above explanation that the same can be done for other factors as well. In addition, the present invention is provided with a storage means for storing the calling number and model information of the destination by operating numbers and destination selection buttons, and by selecting one of the destination selection buttons, the output information of the storage means is Based on this, the calling signal generation means outputs a calling signal, and the control means selects a data transmission method based on the output information of the storage means, so there is no need to perform an operation to call the destination device each time transmission is performed. Therefore, the transmission process is reliable, simple, and time-consuming, and since the recipient's model can be determined based on pre-stored information, the transmission time can be shortened.
This has the effect of realizing efficient transmission.
