Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a telephone device that allows a party receiving a telephone call to identify the other party and refuse to accept the call.

<Conventional technology> In conventional telephone systems, a specific telephone number is assigned to each telephone device, and when a certain telephone number is dialed, the telephone line is connected to the corresponding telephone device, and the telephone line is immediately connected to the corresponding telephone device. The doorbell is set up to work. Therefore, when the doorbell rings, the person receiving the call always picks up the handset and answers the call because it is necessary to confirm who is calling. However, in recent years, this system has been misused to make so-called ``prank calls'' and ``prank calls'' where calls are made to unspecified persons, and this has become a social problem as telephone pollution. However, the conventional system, in which the person on the other end of the call cannot be predicted at all unless the person picks up the handset and answers the telephone, cannot refuse to respond to such malicious calls, making it difficult to resolve this type of social problem.

Recently, we have developed a system where you register in advance the name and code of a specific person you wish to call, and when that person calls, you can receive the call by displaying that person's name and the presence or absence of the registration code. A telephone terminal device was proposed in which the telephone operator could choose how to answer the call (Japanese Patent Application Laid-open No. 4639/1983 and Utility Model Application No. 57/1983).
No. 148956).

<Problems to be solved by the invention> However, in the case of this device, when the doorbell rings, it is not possible to immediately recognize the other party, so each time a doorbell rings, the person on the other end has to go to the place where the telephone is installed and check whether the other party is a registered user or not. It was necessary to check the display to see if it was the case, which was cumbersome.

This invention was made to solve the above-mentioned problems, and it is possible to identify the other party without visiting the place where the telephone is installed, and the calling operation is based on whether or not there is an intention to answer the call. The object of the present invention is to provide a telephone device that realizes the following.

<Means for Solving the Problems> The present invention is a telephone device in which a different telephone code is fixedly assigned to each telephone device, and a code generation system that generates the telephone code assigned to itself at the time of transmission. a mode setting switch for setting a mode for registering the telephone code of a selected telephone device of another person, a keyboard for inputting the telephone code of another person in the registration mode, and a plurality of keys input from the keyboard. a memory having a storage area for registering a telephone code; and transmitting the telephone code generated by the code generation unit to the called party;
A transmitter/receiver unit receives a telephone code sent from another person's telephone device, and compares the telephone code received by the transmitter/receiver unit with the telephone code registered in the memory to determine if the telephone codes match or do not match. A determination unit that makes the determination, a sound generation unit that can generate different ring tones, a timer that measures the sounding operation time of the sound generation unit, and a timer that selects whether or not time regulation is required for the sound generation operation of the sound generation unit. The apparatus includes a selection switch and a control section that controls the sound generation operation of the sound generation section according to the determination result by the determination section and the selection state of the selection switch. The control unit causes the sound generation unit to continuously generate one ring tone when the determination unit determines a match, and causes the generation unit to generate the other ring tone when the determination unit determines a mismatch. At the same time, when time regulation of the sound generation operation is selected by the selection switch, the sound generation operation of the sound generation section is stopped in response to the measured value of the timer exceeding a predetermined value.

<Function> When there is a telephone call, the ring tone differs depending on whether the other party is a registered user or not, so the other party can be identified at the time of the call, and there is no need to go to the location where the telephone is installed. . Moreover, if the user has no intention of answering a call from an unregistered person, by turning on the selection switch, the ringing tone continues for a predetermined period of time and then stops, causing the harsh ringing tone to disappear in a short period of time.

<Embodiment> FIG. 1 shows a telephone device of the present invention. The illustrated device includes a device body 1 in which a keyboard 11, a display 12, a mode setting switch 13, and a selection switch 14 are arranged on an operation surface 10, and a feeder body 1 placed on a support hook 15 on the top surface of the device body 1. It consists of a receiver 2. The keyboard 11 is provided with various keys necessary for normal dialing operations as well as for telephone code registration operations, and the display 12 displays the key-input telephone code during such registration operations. The telephone code is fixedly assigned to each telephone device, and for example, a new code is set and assigned each time a telephone manufacturer manufactures a device. Furthermore, mode setting switch 13
switches between a normal call mode and a registration mode, and a selection switch 14 switches a calling operation method to be described later.

FIG. 2 is a circuit block diagram of the above telephone device. The code generator 3 in the figure generates a telephone code assigned to itself, and also generates a table memory 4.
1 is the key-input telephone code C ₁ , C ₂ , C ₃ ,
... (see the registration table shown in FIG. 3) is registered. The transmitting/receiving unit 21 transmits data related to the telephone number, telephone code, etc., and voice information from the handset 2 to the other party's telephone device via the telephone line 22, and also transmits similar data and voice information from the other party's telephone device. receive. Either one of the first buzzer 5A and the second buzzer 5B operates selectively when making a telephone call, and the first buzzer 5A operates to generate a sound when the call is from a telephone device with a registered telephone code. However, the second buzzer 5B operates to sound when the call is from another telephone device. In this embodiment, the first buzzer 5A and the second buzzer 5B each output different tones, but the present invention is not limited to this, and one can be designed as appropriate, such as outputting a continuous tone and the other outputting an intermittent tone. Can be changed. In the figure, a CRT (Cathode Ray Tube) 6 is provided as necessary, and for example, when making a telephone call, it can display text indicating whether or not the other party's telephone code is registered, and further, it can display the other party's name, telephone code, etc. Used to display directly.

Each of the above output means uses the CPU (Central
The CPU 7 decodes and executes the program in the program memory 4, reads and writes data to and from the RAM 42, and executes various processes, calculations, and the control operations described above.

4 and 5 show the operating procedure of the above-mentioned device example controlled by the CPU 7. FIG. At the start of the figure, the table memory 41 contains telephone codes C ₁ , C ₂ , C ₃ ,
. . . has been registered, the mode setting switch 13 is set to normal call mode, and it is waiting for transmission/reception.

If you now pick up the handset 2' (the structure of the other party's telephone equipment is indicated by a symbol with a dash) and perform a dial operation on the other party's telephone equipment (step 8 in Figure 4).
1, 82), for example, when the telephone line 22 is connected, the transmitting/receiving section 22 is formed in an electrical state in which the handset 2 is picked up, and transmits a confirmation signal to the other party's telephone device (steps 91, 92 in FIG. 5). ).
When this confirmation signal is received by the other party's telephone device, the code generator 3' generates a telephone code, and this generated code is output from the transmitting/receiving section 21' to the telephone line 22 (step 83 in FIG. 4). 84). Then, in step 93 of FIG.
receives the telephone code, then CPU 7
In step 94, the registration table in the memory 41 is referred to, and in the following step 95, the other party's telephone code is sequentially compared with each registered telephone code. If there is a matching code in the registration table, the determination of "Is there a matching code?" in step 96 becomes "YES", and in the next step 97, the first
Buzzer 5A operates. By the buzzer sound, the user can know that the person to be registered is calling, and can immediately pick up the handset 2 and answer the call.

On the other hand, if there is no matching code in the registration table, the determination at step 96 is "NO" and the second buzzer 5B is activated at step 98. From this buzzer sound, the user can know that an unregistered caller is calling, and can refuse to answer the call depending on the current time and other circumstances.

The next step 99 is to determine whether or not the selection switch 14 is turned on. If the determination is "YES", a timer (not shown) is activated in the next step 100, and the timer is activated for a certain period of time (for example, about 5 seconds). When the time has elapsed, the determination in step 101 becomes "YES" and the operation of the second buzzer 5B is stopped (step 102). Therefore, if the user has no intention of answering a telephone call from an unregistered person, it is sufficient to turn on the selection switch 14, thereby causing the annoying buzzer sound to disappear in a short time.
Furthermore, if the user intends to answer a call from an unregistered person, the selection switch 14 is turned off, and in this case, the user either picks up the handset 2 or places the handset 2' on the other party's device. The second buzzer 5 continues to operate until.

In the above-mentioned embodiment, although the telephone is in the talking state from step 91 onwards, until the handset 2 is actually picked up, no information is sent to the other party's telephone device.
It is desirable to send out a ringing tone to indicate that a call is in progress.

<Effects of the Invention> As described above, in this invention, the telephone codes of a plurality of parties to whom a call is desired are registered in advance, and when a call is made, the transmitted telephone code matches the registered code. Since the system determines whether or not the call is true and notifies the result of the determination by generating a different sound, the side receiving the call can
To easily recognize whether or not the other party is the one with whom a telephone call is desired without visiting the place where the telephone set is installed.

What's more, a selection switch has been installed to make it possible to time-regulate the generation of the ringtone for calls from unregistered users, so if there is an intention to answer a call from an unregistered person, the selection switch can be used to cancel the time-restriction on the ringtone. On the other hand, when there is no intention to answer a call from an unregistered person, such as at night, the annoying ringtone can be quickly turned off by setting the time limit for the sound generation operation using the selection switch.
This has the remarkable effect of being able to select a calling operation according to the person's intention, time of day, and other circumstances.
