BACKGROUND OF THE INVENTION
The present invention relates to a facsimile machine. More particularly, the present invention relates to a facsimile apparatus that can use signals such as subaddress, password, and selective polling according to standard procedures.
[0002]
[Prior art]
Facsimile communication procedures are described in Recommendation T. of ITU (International Telecommunication Union) -T. 30. By performing facsimile communication based on this recommendation, facsimile communication can be performed between apparatuses of different manufacturers and models. Recommendations are reviewed as appropriate in light of technological progress and usage patterns. In recent recommendations, a SUB (sub address) signal used for confidential communication, a SEP (selective polling) signal used for selective polling, and a PWD (password) signal used for both of these are newly defined.
[0003]
Here, confidential communication refers to a box in which the calling party is specified by a sub-address without printing out the image data when received so that the image data received by the called party cannot be seen by a third party. Is remembered. When the correct personal identification number is input on the called side, the image data in the box is printed out.
[0004]
In the selective polling, image data is stored in advance in a plurality of boxes of the called facsimile machine, and the selective polling ID and password of the box desired to be received from the calling side are transmitted. The called side searches for a box whose selected polling ID and password specified by the calling side match, and if there is a corresponding box, transmits image data to the calling side.
[0005]
[Problems to be solved by the invention]
However, the SUB signal, SEP signal, and PWD signal specified in the recommendation can input data of up to 20 digits. At the time of transmission, it is necessary to perform operations such as selecting a destination and a function. In addition to these operations, specifying a subaddress having a larger number of digits may cause an erroneous operation.
An object of the present invention is to reduce the labor of inputting a SUB signal, SEP signal, PWD signal or the like having a large number of digits when making a call, and to improve operability.
[0006]

[0012]
Reference numeral 11 denotes a CPU, which controls the above-described units connected by the bus 12 based on a program stored in the ROM 5.
[0013]
Next, the electronic telephone directory stored in the RAM 6 will be described with reference to FIG. The electronic phone book is used at the time of making a call, and for each abbreviated number represented by numbers or one-touch dial represented by letters, a destination name indicating the destination, a destination facsimile number, a subaddress / selection polling ID And an area for storing a password. The sub address / selection polling ID is used for confidential transmission and polling reception, and the password is used only when polling reception is performed.
[0014]
Further, the RAM 6 is provided with a management area for managing an image memory for storing image data, as shown in FIG. Since the image memory is managed in units of boxes, the management area includes, for each box, a box name, a type indicating whether the box is for confidential communication or selective polling, a sub address / selection polling ID, a password, Stores the memory address where the actual image data is stored, the title of the image data stored for selective polling, the password used to print out the image data received in memory during confidential communication, etc. . The box needs to be registered in advance before performing confidential communication and selective polling. Furthermore, in the case of selective polling, registration of image data is also necessary.
[0015]
Next, confidential communication and selective polling when the facsimile apparatus F of the present invention is used for the calling side and the called side will be described. FIG. 4 shows the operation of the calling side device. When the operator performs a call operation, if the user desires transmission using confidential communication or reception using selective polling, the corresponding function is selected from the operation unit 4 (S1). Next, a destination is designated from the operation unit 4 (S2). The destination is designated by abbreviated dialing, one-touch dialing or direct input of a facsimile number.
[0016]
The abbreviated dial assigns a 2-3 digit abbreviated number to the destination facsimile number, and a call is started by operating the abbreviated dial key followed by the abbreviated number and the communication key. The one-touch dial is one in which a unique facsimile number is assigned to each of about 5 to 20 keys, and a destination can be designated and a call can be made with a single key operation. When the facsimile number is directly input, the call is started by operating the communication key after inputting with the numeric keypad.
[0017]
When the destination is designated by speed dial or one-touch dial (S3), it is determined whether the subaddress / selection polling ID and password are registered in the electronic telephone directory (S4). The subaddress / selective polling ID is essential for both confidential transmission and polling reception, but the password is necessary only for polling reception. If it is already registered in the electronic telephone directory, display is performed (S5), and if there is no error in the display contents (S6), the line is closed and a call is made (S9).
[0018]
If it is not registered in S4 or if it is desired to change the display contents in S6, when an input is made (S7), the input contents are newly registered in the electronic telephone directory (S8), and a call is made. (S9). After the call is made, confidential communication or selective polling described later is performed (S10), and the line is released after the communication is completed (S11).
[0019]
If the destination facsimile number is entered using the numeric keypad in S3, after entering the subaddress / selection polling ID and password (S12), if necessary (S13), the destination facsimile number, subaddress, selection polling ID, password Etc. can be registered in the electronic telephone directory (S14). The subsequent steps are the same as described above.
[0020]
Details of facsimile communication in the case of confidential communication will be described with reference to FIG. The caller sends a CNG signal after the call (T1). When the called side receives the CNG signal after answering the incoming call (R1), it sends out a CED signal and a DIS signal (R2). At this time, the called party sets 1 in the 49th bit of the DIS signal and transmits it to indicate that confidential communication is possible.
[0021]
When the calling side receives the CED signal and the DIS signal (T2) and detects 1 in the 49th bit of the DIS signal, it is found that confidential communication with the called side is possible, but if the 49th bit is not 1, (T3) Since confidential communication cannot be performed, the communication is terminated (T9, R9). If the callee can perform confidential communication, a DCS signal is transmitted (T4), and then a subaddress is set in the SUB signal and transmitted (T5). The sub-address set in the SUB signal is the one registered in the electronic telephone book or the one input from the operation unit 4.
[0022]
When the called party receives the SUB signal (R4) following the reception of the DCS signal (R3), whether or not the same subaddress as the subaddress included in the SUB signal is registered in the management area of the RAM 6, That is, it is determined whether or not the box of the designated sub address is registered (R5). If not registered, the communication is terminated (R10, T10). If registered, communication is continued.
[0023]
Thereafter, the modem 2 is trained between the calling side and the called side (T6, T7, R6, R7), and then image data (FAX message) is transmitted from the calling side (T8, R8). On the called side, the received image data is stored in the RAM 6, and when the reception of all the image data is completed, the memory address of the RAM 6 in which the image data is stored is stored in the corresponding box in the management area, and communication is performed. End (T9, R9).
[0024]
As described above, in confidential communication, a sub-address is registered in advance in the box of the called facsimile machine, and the sub-address is designated by the SUB signal from the calling side. The data is stored in the RAM 6 without being printed out. On the called side, a confidential notification is sent to notify that there was confidential communication, and if a correct password is input, it is printed out.
[0025]
Next, details of the selective polling will be described with reference to FIG. The calling party sends a CNG signal after the call (T21). When the called side receives the CNG signal after answering the incoming call (R21), it sends out a CED signal and a DIS signal (R22). At this time, the called party transmits 1 by setting 1 in the 47th bit of the DIS signal to indicate that selective polling is possible.
[0026]
When the calling party receives the CED signal and the DIS signal (T22) and detects 1 in the 47th bit of the DIS signal, it is found that selective polling with the called party is possible, but if the 47th bit is not 1, ( T23 ) Since selective polling cannot be performed, the communication is terminated (T32, R33). If the called party is capable of selective polling, a DTC signal is transmitted (T24), and then a SEP signal and a PWD signal are transmitted (T25, T26). The selective polling ID and password set in the SEP signal and the PWD signal are those registered in the electronic telephone book or input from the operation unit 4.
[0027]
When the called party receives the SEP signal and the PWD signal (R24, R26) following the reception of the DTC signal (R23), the selection polling ID included in the SEP signal and the password included in the PWD signal are received. Then, it is determined whether or not it is registered in the management area of the RAM 6, that is, whether or not the designated selection polling ID and password box are registered (R25, R27). If not registered, the communication is terminated (R32, T31). If registered, a DCS signal is transmitted (R28, T27), and communication is continued.
[0028]
Thereafter, training of the modem 2 is performed between the calling side and the called side (R29, R30, T28, T29), and then the image data (FAX message) designated by the memory address of the box is received from the called side. Transmit (R31, T30). When the transmission of all the image data is completed, the communication is terminated (R32, T31).
[0029]
As described above, in the selective polling, the selective polling ID, password, and image data are registered in advance in the box of the called facsimile machine, and the selective polling ID and password are sent from the calling side to the SEP signal and PWD signal. The designated image data is transmitted from the called side to the calling side.
[0030]
The present invention is not limited to the above-described embodiment, and can be carried out as follows.
(1) Although the facsimile apparatus F supports only one line, the present invention is not limited to this, and the facsimile apparatus F is applicable to a facsimile apparatus or a facsimile system capable of simultaneously communicating with a plurality of lines.
(2) Although the password was used for selective polling, it should also be used for confidential communication. In this case, the password transmitted from the calling side is printed out when it is also input at the receiving side, so that the calling side can have the right to set a password. If the password specified on the calling side is not known in advance, the received document cannot be printed, so that the security can be further improved.
[0031]
