Abstract

PURPOSE:To reject the reception from a party other than a specific caller at a predetermined time band by inputting and storing time zone information from a start time till an end time and a destination number and accepting only the reception from the stored destination at the time zone. CONSTITUTION:When an incoming call comes from an ISDN network 23, time information from a timer 11 and a time stored in time information table 20 are compared and when they are coincident, whether or not the number is a number stored in the number table 21 is checked, various attributes are checked and when no problem exists, the reception processing is proceeded. On the other hand, when the number is not registered or the attributes are not coincident, a release (REL) signal is sent to the ISDN network 23.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a facsimile device, and particularly to a facsimile device connectable to an ISDN network.

[Prior Art] In a conventional facsimile machine, during automatic reception, if the other party's terminal is of a model that can communicate with the own terminal, the facsimile machine receives all the data regardless of the sender. Therefore, even if, for example, the operator of the sending device makes a mistake in inputting the destination number, or if unnecessary information is sent to the receiving device, normal reception processing is performed and the received image is was reproduced on recording paper, etc.

[Problem to be solved by the invention] For this reason, for example, if a large amount of information is sent by a malicious sender, the receiving facsimile machine may run out of recording paper, or most of the memory that stores the received information may become obsolete. may be occupied, making it impossible to receive the information you really need. When receiving such a large amount of information, if there is an operator near the receiving device,
Although reception can be stopped, if there is no operator near the device, such as late at night, the above-mentioned problem may occur.

The present invention has been made in view of the above conventional example, and an object of the present invention is to provide a facsimile machine that does not accept calls from anyone other than a specific caller during a pre-specified time slot.

[Means for Solving the Problems] In order to achieve the above object, a facsimile apparatus of the present invention has the following configuration. That is, it is a facsimile device that is connected to an ISDN network and performs transmission and reception, and includes a number storage means for inputting and storing the destination number, and a time storage means for inputting and storing time zone information from the start time to the end time. and control means for controlling to accept only reception from the destination number stored in the number storage means during the time period stored in the time storage means.

[Operation] In the above configuration, the destination number and the time zone information from the start time to the end time are input and stored, and when that time period comes, only reception from the stored destination number is performed. Works to accept.

[Embodiments] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[Description of Facsimile Apparatus (Fig. 1) 1 Fig. 1 is a block diagram showing a schematic configuration of a facsimile apparatus according to an embodiment.

In the figure, 11 is a control section that controls the entire device;
A CPU 101 such as a microprocessor, which outputs various control signals etc. according to the control program stored in the OM 102 and controls the entire device;
It is used as an I(7)'7-kuniria, and includes a RAM Io3 that temporarily stores various data, a timer 104 that measures time according to instructions from the CPU 101, and outputs an instruction signal to the CPU 101.

Reference numeral 12 denotes an image memory, which stores the image signal read by the reader unit 14 when transmitting a document, and when receiving an image,
Store the received image signal. Reference numeral 13 denotes an encoding/decoding section which encodes the image data read by the reader section 14 during transmission, and decodes the received image data and converts it into original image data during reception. A league unit 14 photoelectrically reads the original image, converts it into a digital signal, and outputs it to the bus 24.

Reference numeral 15 denotes a printer section which inputs the received and decoded image data or the image data from the league section 14 and reproduces and records it on recording paper. Reference numeral 16 denotes a display section such as a liquid crystal display, which displays various messages and functions for the operator. Reference numeral 17 denotes an operation panel operated by the operator to input various instructions, including a numeric keypad 17a for inputting a telephone number, time information to be described later, or reception number, a time setting key 17b for instructing registration of time information, a reception number, etc. It is provided with a number instruction key 17c for instructing the input of .

Reference numeral 18 denotes a receiver interface section that can encode voice information from the telephone set 19 or decode received voice signals and output them to the telephone set 19. Reference numeral 20 denotes a memory for storing time information, which stores the time period for receiving only information from a specific sender, which is input by the operator from the operation panel 17. Reference numeral 21 denotes a number table in which the destination number inputted from the operation panel 17 and received during the time period stored in the time information 20 is stored. 22 is an IS that controls communications on the ISDN network 2
This is a DN communication control unit.

With the above configuration, the time setting key 17 of the operation panel 17
b is pressed to input the time period in which only information from a specific caller is to be received, and by using the time designation key L7c to input a recipient number that can be received during that time period, among those pieces of information, The time zone information is stored in the time information 20, and the destination number is stored in the number table 21. In this way, the timer 1o knows that the time zone set in the time information 20 has arrived.
When recognized by the time information from 4, number table 2
It accepts only calls from the destinations stored in No. 1, and does not enter the receiving operation for other calls.

[Description of Manual Key Processing (FIG. 2)] FIG. 2 is a flowchart showing manual key processing from the operation panel 17, and a control program for executing this input processing is stored in the ROM 102.

This process is started when any key on the operation panel 17 is pressed, and first in step S1 it is checked whether the time setting key 17b has been pressed.

When the time setting key 17b is pressed, the process advances to step S2, and the display unit 16 displays, for example, "start time manually" indicating that the mode is the start time input mode. As a result, in step S3, the start time is entered using the numeric keypad 17a.
For example, at 8 p.m. ha r * 20 * OO * J
is input. Once the start time has been input in this way, the process advances to step S4, and the end time input mode is entered. At this time, "end time manually" is displayed on the display unit 16, and for example, at 8:00 a.m., "r*os*oo*" is input.

In this manner, when the input of the time zone information is completed, the process proceeds to step S6, where the time zone information is stored in the time information 20, and the process ends. As a result, in the above example, the same reception processing as before is performed from 8 a.m. to 8 p.m.
Only incoming calls from designated numbers will be accepted between 8pm and 8am the next morning.

Next, the process of inputting this designated number will be explained.

If the time setting key 17c has not been pressed in step S1, the process advances to step S7 to check whether the number designation key 17c has been pressed. If it is not the number instruction key 17C, the process advances to step S8 and the process corresponding to the pressed key is performed. If the number instruction key 17c is pressed, the process advances to step S9, and waits for a number to be input using the numeric keypad 17a, and when the number is input, it is registered in the number table 21 in step SIO. Since multiple numbers may be registered in step Sll,
It is checked whether the number input process has been completed, and if it has not been completed, the process returns to step S9 and proceeds to the number input process described above. Then, when you are prompted that the number input process is complete,
Key Ends manual processing.

[Description of reception operation (FIGS. 3 and 4)] FIG. 3 is a flowchart showing the reception process after the time information and number information are registered in this way. A control program for executing this process is stored in the ROM 102. ing.

This process starts with the arrival of a call on the ISDN network 2 network 3, and first, in step S21, a call setup message (SET U
When P) is received, the process proceeds to step S22, where the time information from the timer 11 is compared with the time stored in the time information 20, and it is determined whether the current time is a time period in which incoming calls are restricted. When the time zone stored in the time information matches the current time (that is, when the incoming call restriction time zone is reached), the process advances to step S23. In step S23, based on the information included in the call setting, it is checked whether the number is stored in the number table 21.2 If the call is from a destination registered in the number table 21, the process proceeds to step S26;
Check various attributes and if there are no problems, proceed to step S27
Proceed to subsequent reception processing.

On the other hand, if it is not registered in the number table 21 in step S23 or if the attributes do not match in step S26, the process advances to step S24, and ISDNII! '123
A release (REL) signal is sent to the When the release completion signal (REL COM) is received from the network 23, the process ends in step S25. FIG. 4 shows the procedure at this time.

On the other hand, if it is determined in step S26 that reception is possible, the process proceeds to step S27, where the ISDN network 2 network 3 setting reception outputs a message, and in step S28, the ISDN network 2 network 3 output message (ALERT) is output. do. Next, the process proceeds to step S29, where a response message (CONN) is output to the ISDN network 23, and a reception operation begins in step S30. This reception operation is similar to the basic connection sequence in ■SDN, so a detailed explanation will be omitted.

In the above-described embodiment, since accurate information on the rejection of the call cannot be conveyed to the transmitting device, the reason for the rejection of the call can be transmitted to the other party's terminal using a control procedure as shown in FIG. 5, for example.

That is, here, even if the information from the transmitting terminal does not include the calling number information element, a call setup acceptance message is sent in response to the call setup message as in the normal case. Then, a calling message (ALERT), a response message (CONN) are sent, and a response confirmation (CONN ACK) is sent.
When it receives the message, it sends out a disconnection message (Disc) with user information added. This allows the transmitting device to detect, for example, that it is necessary to add a calling number information element to the call setup information.

As a result, if the call cannot be received because the call setting information does not include number information even though it is registered in the number table 21, the other party's terminal can be notified of this fact. By adding such number information and retransmitting, the unreceivable problem can be resolved.

In this embodiment, a key for setting the time or a key for inputting the destination number is provided, but the present invention is not limited to these. For example, the "*" key on the numeric keypad or the "#" key You may also input it in command format using, for example.

As explained above, according to this embodiment, only reception from pre-registered numbers can be accepted during the set time period, thereby preventing the reception of unnecessary or malicious information. effective.

[Effects of the Invention] As explained above, according to the present invention, it is possible to prevent reception from anyone other than a specific caller during a pre-specified time period, which has the effect of preventing reception interference, for example. There is.
