Abstract

PURPOSE:To discriminate whether a communication permission with a specific opposite party is given or not prior to starting communication by providing a means collating a code showing a specific communication opposite party with a previously stored code and permitting the communication with the specific communication opposite party according to the collated result. CONSTITUTION:A communication control equipment is provided with the collating means A collating the code showing the specific communication opposite party with the previously stored code and the deciding means B permitting the communication with the specific communication opposite party based on the collated result. An original to be transmitted is set to an original read part 7, and the telephone number of the communication opposite party is inputted. Then a transmission start key is depressed, and the inputted number of the communication party is decided to be permitted in terms of communication by referring to an outgoing permission control table. If the outgoing is permitted, a call is made, and picture data on the original is read out and transmitted. If the outgoing is not permitted, a display device 4 displays the effect. Accordingly an outgoing possible area and opposite parties can be specified, and the erroneous use of a communication equipment according to the purposes can be eliminated.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a communication control device that allows or disallows communication with a specific party.

[Conventional technology]

Taking a facsimile machine as an example of a communication device, by specifying the destination phone number or code, image data can be sent not only within Japan but also to all areas where communication is possible, including overseas. is possible.

[Problem that the invention seeks to solve]

However, there are cases where it is not desirable to send to a specific destination due to communication charges or other reasons. For example, there is a case where images are transmitted overseas using an old facsimile machine that only complies with the Gl (standard).

As described above, in conventional communication devices, when starting communication, it is not necessary to check in advance whether a call is being made, data is being transmitted, etc. to the communication partner.

Therefore, the object of the present invention is to, before starting excitation,
An object of the present invention is to provide a communication control device that determines whether or not communication with a specific party is previously permitted.

[Means for solving problems]

The communication control device according to the present invention includes means for performing 116 matches between a code representing a specific communication partner and a pre-stored code, and based on the set result, the communication with the specific communication partner described in 1iii. It is permitted to do so.

〔Example〕

Hereinafter, the present invention will be described in detail based on examples.

FIG. 1 is a schematic configuration diagram of a communication control device to which the present invention is applied. A determination means B is provided for permitting communication with a specific communication partner.

According to this device, when you input a destination phone number or code, etc., it determines whether or not calling to that destination phone number or code, etc. is permitted, and if it is not permitted, This notifies the operator of this without making a call.

FIG. 1 is a block diagram showing an embodiment of a facsimile apparatus to which the present invention is applied. In this figure, 2 is a memory that stores data processed by a central processing unit (hereinafter referred to as CPU) 8, which will be described later, as well as a call permission management table (see FIGS. 3 and 4). this keyboard 3
is used to enter the telephone number or code of the other party. Reference numeral 4 denotes a display device for displaying data sent from the CPU 8 and indicating that a call cannot be made. Reference numeral 5 denotes a transmitting device that connects the line 6 to the present facsimile machine and performs a calling operation. Further, BAT is an eight-telephone for backing up the memory 2 when the power is turned off. 7 is a document reading section.

Next, the calling permission number management table shown in FIGS. 3 and 4 will be explained.

First of all, letter of restraint 7. i+-, as shown in FIG. 3, the bin h'b of the calling permission number management table 1. ,bl
and bit b0 of the calling permission number management table 2 are all set to rQJ. In this calling permission number management table 1, p)bo indicates whether to permit local calls, and b)b1 indicates whether to permit outgoing calls.

Further, the calling permission number management table 2 is used to determine whether calling is permitted for each out-of-town area when out-of-town calls are permitted. Here, each number from byte number O to 9 represents the second digit of the destination telephone number, and a call to a specific area is made by referring to bit bo in the same byte number as the second digit number. Determine whether permission is granted.

That is, if the bit used for calling permission in the calling permission number management tables 1 and 2 is "1", it is determined that calling is possible, and in the case of rOJ, calling is not possible. Note that bits that are not used for determining permission to make a call are indicated by an X, and do not affect the determination of permission to make a call.

In the initial state, as shown in Figure 3, all bits for calling permission determination in the calling permission number management table are "0".
Therefore, this facsimile machine is set in a state in which it cannot make any outgoing calls. Therefore, a call permission number is input from the keyboard 3 (see FIG. 2) so that calls can be made only to certain areas within the city and outside the city. Then, the data is transferred to the calling permission number table 1 and the calling permission number table 2 in the memory 2 via the CPU 8.
, and the value shown in FIG. 4 is obtained.

In the example shown in FIG. 4, since both BO and BL of the call permission number management table 1 are "1", calls within and outside the city are permitted.

However, since the bit bo is "1" only for byte 3 and byte 4 of the calling permission number management table 2, this indicates that calls can only be made to areas 3 and 4 for long-distance calls. There is.

FIG. 5 is a flowchart showing the calling control procedure of the embodiment shown in FIG.

First, a document to be sent is placed in the document reading section 7 (step S2), and the telephone number of the communication partner is input (step S3).

Next, the transmission start key is pressed (step S4), and it is determined whether or not the previously input communication partner number is permitted to make a call by referring to the call permission management table (step S5). Here, as shown in Figure 4, outgoing calls are permitted only when the other party's number indicates an area within the city limits or when the area number indicates an area of 3° or 4°. ing.

If calling is permitted, make the call (step S
6), read the image data of the original (step S7),
The data is transmitted (step 58).

On the other hand, if the call is not permitted, a display indicating that the call is not permitted is displayed on the display device 4 (step 5IO).

Note that instead of using the display device 4, it is also possible to use audible means such as a speaker or a bell.

〔Effect of the invention〕

As explained above, according to the present invention, by providing a call restriction function, it is possible to specify areas, destinations, etc. where calls can be made, and therefore it is possible to properly use communication devices without error.

For example, facsimile machines with high price and high transmission speed,
By selectively using a facsimile device that is inexpensive and has a slow transmission speed, it is possible to reduce the cost of continuous use.
