[0003]
Further, as this kind of apparatus, there is an apparatus proposed in Japanese Patent Application Laid-Open No. 4-119747.
In this device, when a call from a calling side is input to a signal receiving unit of a telephone device via a communication network, and then a reading unit reads a calling ID, whether or not the calling ID is registered in a registration list is determined. It checks whether or not it is registered, activates the response unit, sends a predetermined response message to the caller, and disconnects the line. By registering a calling ID whose reception is to be refused in advance in the registration list, it is possible to repel unwanted calls such as “mischief calls”, “silent calls”, and “product solicitations” without responding. Become.

The ROM 2 stores a program for executing the operation according to the present embodiment and a predetermined message output via a display of the operation display unit 4.
The RAM 3 is composed of an image information storage unit 4 for storing image information to be transmitted and received, and a management table 5 for storing the telephone numbers of the destinations for which calling is prohibited and their expiration dates.
The RAM 3 is a non-volatile memory, and retains stored information even when power is not supplied to the apparatus due to a power failure or the like.
The operation display unit 6 includes various operation keys necessary for operating the facsimile apparatus, such as a start key, a numeric keypad, a communication refusal key for instructing communication refusal, a release key for instructing release of communication refusal, and setting of various modes. It consists of a display for displaying a message for status and operation guidance.
[0018]
The network control unit 7 is connected to the line L and executes a predetermined line control when making or receiving a call.
The modem 8 transmits and receives a procedure signal for transmission control during facsimile communication, and modulates and demodulates image information for transmission and reception. Further, the modem 6 detects a rejection signal indicating rejection of communication and a release signal indicating release of communication rejection sent from the other party, and generates these rejection signals and release signals according to a command from the system control unit 1. And has the function of sending out to the line L.
The encoding / decoding unit 9 encodes the image information read by the image reading unit 10 and compresses the data using a known encoding method such as MH (Modified Huffman Coding), and receives the data via the network control unit 7. The image information is decoded and returned to the original image information. The image reading unit 10 reads image information of a document at a predetermined resolution, and the image recording unit 11 records image information on a recording sheet at a predetermined resolution.
In the above configuration, the system control unit 1, the ROM 2, the RAM 3, the operation display unit 6, the network control unit 7, the modem 8, the encoding / decoding unit 9, the image reading unit 10, and the image recording unit 11 are connected via the bus line 12. Exchange data.
[0019]
Next, the transmission operation of the facsimile apparatus according to the embodiment of the present invention will be described with reference to the flowchart shown in FIG.
First, when the telephone number of the called party is input via the operation display unit 6 (Yes in step 1), the system control unit 1 determines whether the telephone number is stored in the management table 5, that is, It is determined whether the telephone number is a call-prohibited telephone number (step 2).
If it is determined that the input telephone number is stored in the management table 5 as a call-inhibited telephone number, the process proceeds to step 3 without executing the call, and the predetermined message stored in the ROM 2 For example, a message, such as "the communication / call is rejected," is output via the operation display unit 6, and the transmission operation ends.
[0020]
On the other hand, if it is determined in step 2 that the input telephone number is not stored in the management table 5, the telephone number is sent out to the line via the network control unit 7 to make a call (step 4). ). Thereafter, when the line is connected to the communication terminal of the other party, a telephone call or communication is started based on the request of the operator (step 5).
Step 6 is a step of determining whether or not the call or communication has ended and the line has been disconnected. Here, if it is determined that the line has been disconnected, the calling operation is terminated and the process returns to the standby state.
When it is determined that the line is connected during a call or communication (Yes in step 6), it is determined whether or not a rejection signal indicating communication rejection has been received from the communication terminal device of the other party (step S6). 7). If it is determined that the rejection signal has not been received, the process returns to step 6 to continue the call / communication.
The modem 8 detects that the signal transmitted from the line is a rejection signal, and when the system control unit 1 determines that the rejection signal has been received, the user ID transmitted together with the rejection signal to the management table 5 The telephone number of the other party and the expiration date for storing these data as valid are stored in association with each other (step 8). The user ID is a four-digit number set in the apparatus, and is also used when performing confidential communication.
The expiration date is basically one week (168 hours) from the point of receiving the rejection signal, and this value can be arbitrarily set / changed via the operation display unit 6.
[0021]
Step 9 is a step of determining whether or not a cancellation signal indicating cancellation of communication refusal has been received from the communication terminal apparatus of the other party.
Here, the modem 8 detects that the signal transmitted from the line is a release signal, and if the system control unit 1 determines that the release signal has been received, the telephone number of the destination stored in the management table 5 is stored. The data of the number, the user ID, and the expiration date are deleted (step 10).
Next, it is determined whether or not the release key of the operation display unit 6 has been pressed by the operator (step 11). If it is determined that the release key has been pressed, the release signal and the user ID are transmitted to the communication terminal of the other party via the modem 8 (step 12), and thereafter, the flow returns to step 6 to continue the call / communication. .
[0022]
Next, a receiving operation of the facsimile apparatus according to the embodiment of the present invention will be described with reference to a flowchart shown in FIG.
When an incoming call from the line is detected (Yes in step 21) and the line is connected to the communication terminal of the other party (step 22), a call or communication is started based on a request from the operator (step 23). .
Step 24 is a step of determining whether or not the call or communication has been completed and the line has been disconnected. Here, if it is determined that the line has been disconnected, the receiving operation ends and the process returns to the standby state.
On the other hand, when it is determined that the line is connected during a call or communication (Yes in step 24), it is determined whether or not a cancellation signal indicating cancellation of reception rejection has been received from the communication terminal apparatus of the other party. A decision is made (step 25). If it is determined that the cancellation signal has not been received, the process returns to step 24 to continue the call / communication.
The modem 8 detects that the signal transmitted from the line is a release signal, and if the system control unit 1 determines that the release signal has been received, the user ID transmitted together with the release signal is checked. The telephone number and expiration date registered in association with the user ID are deleted from the management table 5 together with the user ID (step 26).
[0023]
Step 27 is a step of judging whether or not the operator has pressed the communication rejection key of the operation display unit 6. If it is determined that the communication refusal key has not been pressed, the process returns to step 24 to continue the call / communication.
On the other hand, if it is determined that the communication rejection key has been pressed, the rejection signal and the user ID are transmitted to the communication terminal of the other party via the modem 8 (step 28). At this time, the system control unit 1 starts a timer for measuring a predetermined time (in this embodiment, 15 seconds is set).
Step 29 is a step for judging whether or not the release key of the operation display unit 6 has been pressed by the operator. If the operator accidentally presses the communication rejection key and then presses a release key for canceling the communication rejection key, the system control unit 1 sends the release signal and the user ID via the modem 8 to the destination. It is sent to the communication terminal device (step 30).
[0024]
Step 31 is a step for judging whether or not the timer started immediately after the transmission of the rejection signal and the user ID has timed out. Here, pressing of the release key is monitored until the timer times out.
After the transmission of the rejection signal, if a predetermined time has elapsed without pressing the release key for releasing the communication rejection (Yes in step 31), the system control unit 1 forcibly transmits the request via the network control unit 7. To terminate the receiving operation.
[0025]
Next, the management operation of the facsimile apparatus according to the embodiment of the present invention using the management table will be described with reference to the flowchart shown in FIG.
This management operation is repeatedly started at a predetermined timing on condition that the apparatus is in a standby state.
First, the system control unit 1 checks whether data (telephone number, user ID, expiration date) is stored in the management table 5, and if the data is stored, reads out the stored data from the oldest one. Is performed (step 41).
Next, data of the expiration date is extracted from the read data, and the extracted data is compared with the current date and time to determine whether the expiration date has passed (step 42). Here, when it is determined that the expiration date of the data has not elapsed, the management operation ends and the process returns to the standby state.
On the other hand, if it is determined that the extracted expiration date has already passed, those data are deleted from the management table 5 (step 43).
When the data erasure is completed, the system control unit 1 checks the management table 5 again to confirm whether there is any other stored data.
If it is confirmed that there is other data stored in the management table, the process returns to step 42 and the validity period of the data is checked again.
When there is no other data stored and the confirmation of all data is completed, the management operation is completed and the process returns to the standby state.
[0026]
In the above-described embodiment, the configuration in which the communication rejection key and the release key are separately provided has been described. However, it is also possible to use a single key and use the stop key together. It is.
Further, although the time during which the communication refusal can be canceled is set to 15 seconds, it is needless to say that the operability is further improved by changing the time by inputting from the operation display unit 6.
[0027]
【The invention's effect】
As described above, according to the configuration of the present invention, it is determined whether or not the telephone number of the destination specified at the time of calling is stored in the management table, and the telephone number of the specified destination is stored in the management table. If it is determined that the call has been made, the call is prohibited. Therefore, the call itself is prohibited to the other party who makes a nuisance call such as “mischief call”, “silent call”, “product invitation”. And the line is not occupied by such useless incoming calls.
[0028]
Further, when the communication rejection key is pressed at the time of receiving a call, a rejection signal is sent to the other party via the rejection signal sending unit. Since the telephone number of the own station is stored, the trouble of registering each station manually is eliminated.
[0029]
Further, when it is detected that a cancellation signal is sent from the other party during line connection, the telephone number of the other party is deleted from the management table, so that the communication rejection key is pressed by mistake. However, the correction can be easily performed.
[0030]
If it is determined that the telephone number of the designated destination is stored in the management table, the call is prohibited and a message indicating the fact is output via the display unit. Can be easily recognized by the operator when the is not executed.
[0031]
Further, when the expiration date has passed, the stored telephone number is deleted from the management table, so that the amount of memory for the management table can be kept to the minimum necessary, and when the operator using the device changes. This eliminates the need to keep storing data unnecessarily.
