DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the embodiments shown in the drawings.

FIG. 1 is a block diagram of a facsimile apparatus adopting the present invention. The apparatus of FIG. 1 is configured as a compound terminal capable of word processing, database processing, facsimile communication and the like.

In the figure, reference numeral 1 is a CPU composed of a microprocessor or the like, and the system bus 11 of the CPU is connected with the members shown in the drawing. ROM2 is CPU1
The control program described later is stored. RAM3 is CP
It is used as a work area for U1, and is used as a storage area for word processor processing, database processing, or image data in facsimile communication.

The CRT 4 and the keyboard 5 are for a user interface and are used for data input in word processing and data display by full screen editing. The keyboard 5 is also provided with various function keys and ten keys for controlling facsimile communication.

The keyboard 5 is provided with a rejection switch 5a for rejecting reception, which will be described later.

The external storage device 6 is used for storing various user data and transmitted / received image data, and is composed of a floppy disk drive or a hard disk drive.

An NCU (network control unit) 7 and a modem 8 are interfaces with a communication line 12 such as a telephone line. The NCU 7 connects and switches the communication line 12, and the modem 8 modulates and demodulates a facsimile procedure signal and an image signal. I do.
The NCU 7 and the modem 8 can be used not only for facsimile communication but also for personal computer communication, for example.

The printer 9 and the scanner 10 are for inputting / outputting a facsimile image, and are constructed on the basis of various known recording output systems or image reading systems. Note that reference numeral 13 is a handset for manual line control or communication.

Next, the operation of the above configuration will be described.

In the above configuration, the encoded image information (facsimile data) received from the communication line 12 via the NCU 7 and the modem 8 is decoded and recorded by the printer 9, or the received image information is stored externally. Stored in device 6.

Further, in the apparatus of this embodiment, when carrying out automatic facsimile reception, a list of telephone numbers and user abbreviations of the partner stations which may receive facsimiles is stored in advance in the RAM 3, and the data of this list is stored. The contents and the data received from the partner station at the time of the incoming call are compared, and the data reception is permitted only when these data match. Normally, the telephone number of the partner station and the user abbreviation are to be notified in a facsimile procedure signal.

The list may be a list of partner stations that are permitted to receive, or conversely may be a list of partner stations that are rejected. Here, a valid flag area is provided in the list, and the data set of the entry whose flag is "1" is treated as the reception permit list, and the data set of the entry whose valid flag area is "0" is treated as the reception refusal list. In the following, an example in which a data set of entries whose valid flag area is “0” is treated as a reception refusal list will be shown. According to the above configuration, the list data for controlling the data reception can be easily edited only by rewriting the flag area.

FIG. 3 shows an edited state of the list using the CRT 4 and the keyboard 5. Here, the telephone number and the user abbreviation of the partner station for controlling the incoming call reception are edited in full screen as shown in the table format.
The user can easily edit (input / change) the list of the reception-permitted partner stations by full-screen editing using the CRT 4 and the keyboard 5.

The list for controlling incoming calls thus created is stored in a predetermined area of the RAM 3 in a predetermined table format. This storage area may be stored by a backup power supply such as a battery even when the main power supply is cut off. Alternatively, it is conceivable to store these data using the external storage device 6 or the like.

FIG. 2 shows a control procedure by the CPU 1 at the time of image reception. The reception routine of FIG.
It is activated upon receipt of a call (CI) signal from step 2 (step S1).

In step S2, the relay of the NCU 7 is switched to the modem 8 side and the communication line 12 is connected to the modem 8. Then, in step S3, CCITT recommendation T. Facsimile communication procedure defined in 30 or the like is executed to determine the reception mode. At this time, the identification data such as the telephone number of the partner station and the user abbreviation transmitted by the procedure signal from the partner station is received. These identification data are displayed on the CRT 4 as needed (for example, when the received data is not recorded and output and the received data is stored in the external storage device 6) during the receiving process.

In step S4, it is checked whether or not the telephone number and the user abbreviation of the currently connected transmitting device received in step S3 are registered in the reception refusal list registered in the RAM 3 in advance by the procedure of FIG.

In step S5, the process branches depending on the result of the determination in step S4. If not registered in the rejection list, the process proceeds to step S6 to start the normal reception process for the first page.

In this way, the image information is received in step S6 and is printed out (or stored in the external storage device 6) using the printer 9 in step S7.

Record output (or display of identification data such as the telephone number of the partner station, user abbreviation, etc., performed in the external storage device 6)
When the user who sees it determines that "reception is not necessary", he / she presses the rejection switch 5a.

The depression of the rejection switch 5a is detected in step S8. When the pressing of the rejection switch 5a is detected in step S8, the recording output (or the storage in the external storage device 6) on and after the next page is stopped, and the other party's telephone number, user abbreviation, etc. are automatically set in step S9. Register on the rejection list.

On the other hand, if the rejection switch 5a is not pressed in step S8, it is determined in step S10 whether or not the reception data is completed. If not, the reception and recording output (or storage in the external storage device 6) is continued. .. Thereafter, in step S11, a normal termination protocol is performed, the line is disconnected in step S13, and the reception process is terminated.

When the reception is rejected in steps S5, S8, and S9, the process proceeds to step S12, the error termination protocol is executed, the line is disconnected in step S13, and the reception process is terminated.

According to the above-mentioned embodiment, when the telephone number or the user abbreviation is included in the reception refusal list created in advance, the data transmission from the partner station is rejected, and the other partner stations are rejected. You can only allow data to be received from. Therefore, it is possible to receive the facsimile data such as the direct mail and the mischief, and prevent the unnecessary line occupation and the waste of the recording paper and the memory area.

In the above embodiment, the telephone numbers and user abbreviations are illustrated, and these are stored as a list and compared with the data in the procedure signal of the partner station, but a predetermined password or the like is stored. It is also possible to compare these. Further, both the telephone number and the user abbreviation may be matched under the AND condition, or the matching may be performed under the OR condition such that the reception is performed when only one of them matches.

In the above embodiment, the items of the reception refusal list are only the telephone number of the other party, the user abbreviation, the valid / invalid flag of the list, and the refusal switch. However, a means for designating the refusal number is added to this. It is also possible to monitor the reception status of unnecessary facsimiles.

Further, in the above, the switch 5a is a rejection switch, but it may be configured as a switch that acts so as to continue the communication only when it is pressed and to stop the communication when it is not pressed. Further, the automatic registration of the list when the switch is pressed can be replaced with the registration of the incoming call permission flag.

The list shown in FIG. 3 can also be shared as speed dial or one-touch dial data used for automatic calling. Further, it can be used not only for facsimile transmission / reception but also when the apparatus of FIG. 1 performs personal computer communication using the NCU 7 and the modem 8. In such a case, it goes without saying that the data reception can be permitted or prohibited by the same procedure as the above-mentioned procedure if the apparatus performs the automatic incoming call processing.
