DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile machine.

[0002]

2. Description of the Related Art A facsimile machine is used for unnecessary communication by direct mail or the like utilizing facsimile communication, which hinders receiving an urgent communication from another calling station, and which is not necessary. The printing of the content on the recording paper causes a problem that the recording paper is wasted.

For this reason, the TSI sent from the calling station
(Calling station identification), and sequentially compares the identification information of the calling station with the identification information registered in advance as that of the partner station to which communication is permitted.
A facsimile apparatus in which the procedure is interrupted when the subsequent procedure and data communication are continued but there is no match is considered.

[0004]

However, as described above, if the procedure is interrupted during the communication, the calling side may determine that the communication procedure has been abnormally terminated. In such a case, the facsimile machine on the calling side may call again, and the called side may receive a useless incoming call many times.

SUMMARY OF THE INVENTION In view of the above circumstances, an object of the present invention is to provide a facsimile apparatus which can avoid a situation where a calling facsimile apparatus calls again.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a facsimile apparatus according to the present invention is registered in advance as identification information of a received calling station and that of a partner station to which communication is permitted. Means for comparing with the identification information, and means for controlling to receive the image data but not to print and store the image data when it is determined that they do not match according to the comparison result. . Further, in the facsimile apparatus according to the present invention, when it is determined by the comparing means that they do not match, the transmission speed can be set to the highest speed when receiving the image data. Also,
The facsimile apparatus according to the present invention can be set so that, when it is determined by the comparing means that they do not match, when receiving the image data, a positive response can be made even if an error is included. Further, in the facsimile apparatus according to the present invention, it is possible to switch the validity / invalidity of a means for controlling so as to receive image data but not to print the image data and store it in the memory.

[0007]

According to the above arrangement, for a partner who is not registered in advance as permitting communication, image data is received but image data is not printed and stored in memory (hereinafter, this processing is referred to as disguised reception). Therefore, the consumption of the recording paper and the use of the memory in printing of unnecessary contents are avoided. Since the reception of the image data is executed to the end without interruption, the calling side determines that the transmission has been completed normally and avoids the call again. The received image data is discarded without being printed or stored in the memory. Even if there is an error, there is no inconvenience. If communication is performed using the highest transmission rate, the communication time can be reduced. Of course, there is no need to perform composite processing of image data. Further, the convenience is further added by enabling the switching instead of uniformly printing the image data and storing the image data in the memory.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. FIG. 2 is a block diagram showing a schematic circuit configuration of the facsimile apparatus. The facsimile apparatus controls the entire facsimile and, as described later, performs normal reception and impersonation in accordance with the received calling station identification information. A control unit 1 that can perform switching control for reception and the like, a RAM 2 that stores transmission data, reception data, a telephone number, and the like, and stores identification information of a partner station to which communication is permitted, and an automatic unit for performing dial transmission. A dialer 3, an NCU 4 for controlling a line, a reading unit 6 for optically reading the contents of a document set on a document table, a modem 7 for performing a modulation / demodulation process, and a thermal head for transferring heat in dot units to recording paper. In addition to recording the image data by applying the data, a recording unit 8 for recording a journal report related to fake reception and a program necessary for the operation of the control unit 1 are stored. And ROM9 are, ten keys, one-touch keys, an operation panel 10 provided with such function keys, and a display unit 11 made of LCD.

Registration of the identification information of the partner station to which communication is permitted is performed, for example, by operating a function key and a numeric keypad for several digits to call an identification information registration mode.
It can be performed by inputting a subscriber number, a maker code, a predetermined ID number, and the like with ten key operations. Also, without separately registering, a telephone number registered for abbreviated dialing or one-touch dialing may be used as identification information and its telephone number may be used as identification information.

[0010] In addition to switching between enabling and disabling the camouflage reception function, a predetermined key operation can be performed, and switching between enabling and disabling the camouflage reception function during a time period designated by the user. Is also possible. In the same manner as the above-described registration of the identification information, the registration of the time period can be performed by operating the function keys and the numeric keys for several digits to call the identification information registration mode, and inputting the start time and the end time by operating the numeric keys. It has become.

FIG. 1 is a flow chart showing the processing at the time of reception and the creation of a journal report concerning fake reception and the printing processing performed by the control unit 1. First, it is determined whether there is an incoming call (S1). If there is an incoming call, NSF, CS
Send I, DIS (S2), NSS, TSI, DCS
Is received (S3). Then, the TSI is stored (S
4) It is determined whether or not any of the identification information registered in advance as that of the partner station to which communication is permitted matches the identification information of the calling station of the TSI (S6). If there is a match, the process proceeds to the normal reception process (S7), while if there is no match, it is determined whether or not forgery reception is enabled (S8). If it is not valid, the process proceeds to step 7, while if the forgery reception is set to valid, the time zone data is read (S9), and it is compared with the current time to determine whether or not it is within the valid time (S10). ). If it is not within the valid time, the process proceeds to step 7, while if it is not within the valid time or when there is no time zone setting, the camouflage reception mode is set (S11). That is, in order to select the highest transfer rate when deciding the transfer rate with the calling station during training, communication can be performed at the highest transfer rate even if an error may occur at that transfer rate. Is transmitted to the calling station, and upon receiving subsequent image data, a setting is made so that a positive response is made even if an error is detected. Further, a non-write signal is applied to the WR terminal of the RAM 2 Then, after setting so as not to output the write address and not to supply the image data to the recording section 8 and to drive the thermal head and the paper feed motor, the image data is received (S12). Therefore, neither the process of storing image data in the RAM 2 nor the printing process of the recording unit 8 is performed. Next, it is determined whether or not the image data ends (S1).
3) When the process is completed, the contents described in the journal report regarding the spoofed reception, for example, the TSI of the calling station
And the communication time are stored in the memory (S14), the TSI stored in step 4 is deleted (S16), and the process returns.

On the other hand, if it is determined in step 1 that there is no incoming call, it is determined whether there is a report creation request (S1).
7) If there is a creation request, print a journal report on disguised reception describing that the received image data has been discarded, in addition to the contents stored in step 14 such as the TSI, communication time, communication time, and the number of originals. (S18). According to the above configuration, the printing of the image data and the storage of the memory are not performed for the other party who is not registered in advance as permitting the communication, while the communication procedure is being executed. Consumption and memory usage are avoided. Then, since the communication procedure is executed to the end without interruption, the calling side determines that transmission has been normally completed, and avoids calling again.

[0013] Further, since a journal report relating to fake reception is prepared, it is possible to know from whom and when unnecessary communication was received. In addition, since fake reception can be enabled / disabled during the time period, time periods with many direct messages, for example,
It is possible to select to enable fake reception only at night and to disable fake reception during working hours.

The received image data is discarded without being printed or stored in the memory, and there is no inconvenience even if it contains an error. Even if there is, a positive response is given, and communication is performed using the highest transmission rate to reduce the communication time.

In this embodiment, the G3 facsimile has been described. However, the same fake reception control can be performed for the G4 facsimile based on the calling station identification information included in the setup message.

[0016]

As described above, according to the present invention, the use of the recording paper memory in unnecessary reception can be avoided, and
Since the reception of the image data is executed to the end without interruption, the calling side determines that the transmission has been completed normally, and has the effect of avoiding re-calling.
