Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Field of Application) The present invention relates to a telephone device that controls the blinking and lighting of a predetermined lighting Vi according to an incoming call signal from a telephone.

(Technical Background of the Invention) General telephones notify incoming calls using a ringing signal, and at night or in a dark place, it is difficult to locate the telephone itself. There is a lot to search for. Also, if you need to take notes during a call, especially at night while you are sleeping, you must turn on the lights around the phone or in the room. I had to operate the switch. Of course, there are ways to make the presence of the phone clear by making the light source built into the phone flash, or by flashing a separate guide lamp, in synchronization with the 16112 ringing signal used in the phone. When the handset of the telephone is turned off-hook, the ringing signal stops and the flashing light also goes out, so the light is not bright enough to take notes. Therefore, even if you can know where the phone is located, if you need to take notes, etc., you will have to search for the light switch, etc., and turn on the light.
I have to.

(Means for Solving the Problems of the Invention) Although conventional telephones have the ability to light up at the level of an indicator lamp, they are not electrically connected to a lighting device capable of taking notes, making it difficult to receive calls at night. In some cases, it was a hassle to have to turn on the light to take notes.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, it is an object of the present invention to provide a telephone lighting control system that can control lighting equipment in response to the incoming call operation of a telephone.

[Structure 1 of the Invention (Means for Solving Problems) This invention has an incoming call detecting means in which the main body of the telephone device detects a ringing signal from a line, and a switch that does not indicate the off-hook or on-hook state of the telephone handset, and furthermore, The present invention is characterized in that a pulse generating means is provided which generates a pulse during a calling signal period and a period after off-hook by the output of the detecting means, and the lighting equipment is controlled by the output of the pulse generating means.

(Function) According to the present invention, when a call is received, the light that illuminates the area around the telephone is blinked to notify the user of the call, and when the handset is taken off-hook, the light is automatically turned on continuously. Also, after the call ends, the light is turned off by putting the handset on hook.

(Embodiments) The present invention will be explained below with reference to illustrated embodiments. 1st
The figure is a circuit diagram showing one embodiment of the telephone device according to the present invention, and FIG. 2 is a perspective view showing the external appearance of the system of FIG. 1. As is clear from FIG. 2, the telephone device according to this embodiment has a dedicated lighting device 2 built into the telephone 1 itself.

The overall circuit configuration of this embodiment is as shown in FIG. In FIG. 1, a line 3 formed by lines L1 and 12 is connected to a telephone circuit 4 and an incoming call detection circuit 6, and the telephone circuit 4 and incoming call detection circuit 6 are configured to be switchable with a handset 5. The switch 7 is a hook switch for the handset 5, and is non-conductive when the handset 5 is placed on the telephone device main body 1. Further, the switch 11 is an operation selection switch of this system. For example, during the daytime, this switch 11 is made non-conductive, and when the user sleeps for a long time, the same switch 11 is kept conductive. When the switch 8 is in the a position, it is in a completely operational "OFF" state, and the electric light 9 is turned off independently of the telephone 1. The b position is the position for performing the operation according to the invention. The position is a position in which the electric light 9 is turned on regardless of the telephone 1.

The electric light 9 has one end connected to a commercial alternating current power (AC) outlet 10.
is connected to one line of the hook switch 7, and the other end is connected to one end of the hook switch 7 and a contact point P3. corresponding to the C position. A phototriac 12 is connected to one of P4 and is optically coupled to the incoming call detection circuit 6 between one contact of the switch 11.
has been established. The other end of the hook switch 7 is connected to the other end of the switch 11, and is also connected to P2 of contacts P2 and P3 corresponding to the b position. Furthermore, the other line of the AC outlet 10 is connected to a contact P3 of the switch 8. Note that the contact P4 of the switch 8 is an unmanned terminal.

FIG. 3 shows an example of the incoming call detection circuit 6, in which lines L1 and [
(connected in anti-parallel to 2 questions) 1st diode CD11,
a direct current detection circuit 13 having a CD 12; a light receiving circuit 14 having phototransistors CD21 and CD22 coupled to the photodiodes CD11 and CD12; and an integrating circuit 15 that integrates the output of the light receiving circuit 14.
The comparator 16 compares the output of the integrating circuit 15 with the U* voltage V1 and controls the photodiode CD5 based on the comparison output. Note that the photodiode CD5 is coupled to a phototriac 12.

The operation of the telephone device having the above configuration will be explained with reference to FIG. Handseller l-5 is currently on hook,
Further, if a call signal is received while the switch 8 is in the b position and the switch 11 is in a conductive state, the voltage generated at the point A at this time is 1[ as shown in FIG. 4(b).
This results in a plurality of pulse voltage trains corresponding to the storage signals for each [SeC].

This pulse voltage is integrated by the integrating circuit 15 and appears at the terminal B as an integrated waveform as shown in FIG. 4(C). The signal from terminal B is compared with the reference voltage V1, and during the period in which the integrated waveform is higher than ■1, a signal (see Figure 4 d) exhibiting a high level appears at the terminal during the tapping call signal period. . This allows the photodiode CD
5 passes through (\), and the triac 12 turns on (see Figure 4 e and f).

When the triac 12 is turned on, AC voltage from the AC outlet 10 is applied to the lamp 9 in the circuit shown in FIG. Therefore, as shown in FIG. 4(g), the electric light 9 performs an intermittent lighting operation in which it is turned on during the ON operation of the triac 12 (during the ringing signal period) and turned off during the 2 [sec] call pause period. If you pick up the handset 5 under this condition, the hook switch 7 becomes conductive.
The electric light 9 is in a continuous lighting state.

Next, when the call ends and the handset 5 is put down (off-hook state), the hook switch 7 becomes non-conductive, but since there is no 6-phone ringing signal, the phototriac 12t1''OF
Since it is in the F'' state, the light 9 turns off.In addition, the switch 8
When the position is set to C and the cell 1 is turned on, the light 9 can be turned on continuously regardless of the handset 5, so it can be used as a general lighting stand.

In addition, during the daytime or when other lights are on and there is no need for the light 9 to blink or turn on when a call arrives, by setting the switch 8 to the C position, the switch 11 and all lights will be off regardless of whether there is an incoming call. It can be done. On the other hand, if it is necessary to turn on the electric light 9 under all conditions,
It is sufficient to set the switch 8 to the C position as described above. Furthermore, if you do not need the flashing illumination during shield communication, switch 11
If only the phototriac is made non-conductive, the phototriac 12
Even if it operates, a closed loop between the light 9 and the AC outlet 10 is not established, and the light 9 lights up only when the handset 5 is picked up. The above combinations are shown in the table.

Next, another embodiment will be described with reference to FIG.

In this embodiment, the electric light 9 is controlled by remote control from the telephone body 1. The telephone main body 1 is basically constructed in the same manner as shown in FIG. 1, and includes a telephone circuit 4, an incoming call detection circuit 6,
It is composed of a handset 5, switches 7, 8, and 11, a triac 12, an infrared light emitting section 22, and a voltage source 21 that drives this light emitting section 22. Here, voltage source 21
is input terminal P5. When current flows between output terminals P6 and P7.
One of the input terminals P5 is connected to the line [2, and the other P6 is connected to the contact P of switch 8.
4, one end of the triac 12 and the hook switch 7
It is connected to the.

Further, the infrared light emitting section 22 is located between the output terminals P7. Connected to P8.

On the other hand, on the side of the lighting equipment to be remotely controlled, one end of the electric light 9 is connected to one line of the AC outlet 10 via the switch 23, and the other end of the electric light 9 is connected to the other line of the AC outlet 10. The switch 23 is controlled "ON" and "OFF" by a switch driving circuit 28.

This switch drive circuit 28 amplifies the output of the infrared light receiving section 27 that receives the remote control signal from the infrared light emitting section 22. Light receiving section 27
is operated by the voltage from the power supply circuit 25. The switch 26 is for operating the electric light 9 during normal use, and the reference numeral 29 is a pilot lamp of the power supply circuit 25.

In the above, the switch 8 is set to the b position and the switch 11 is set to the "ON I+" state as in the previous embodiment. When a 16 tlz calling signal is detected under this state, as shown in FIG. As explained above, the triac 12 is conductive during the ringing signal period, and a current flows between the input terminals P5 and P6 of the voltage source 21.

Therefore, the infrared light emitting section 22 operates, and the light receiving section 27 on the lighting equipment side. The switch 23 is made conductive via the switch drive circuit 28. As a result, the electric light 9 is turned on during the calling signal period. Furthermore, when the handsera]-5 is off-hook, the triac 12 maintains the conductive state, and the infrared light emitting section 22
continues to emit light, causing the electric light 9 to remain lit continuously.

In the case of the embodiment shown in FIG. 5, the telephone line voltage can be used as the power supply voltage of the voltage source 21 for the light emitting section, and the power consumption thereof is also low. Therefore, only the light emitting circuit system is connected to the telephone line 3. All you need to do is equip it with the following equipment, and it will make your rental vehicle more compact.

Also, of course, as in FIG. 1, by combining the switches 8 and 11, it is possible to freely set the electric light 9 to blink or turn on or off (see the table).

Further, although the remote control operation according to this embodiment uses infrared rays as a medium, it is also possible to use FM transmission and reception, ultrasonic waves, etc.

[Effects of the Invention] As explained above, according to the present invention, it is possible to turn on the lighting lamp intermittently by detecting a telephone discharge signal, and to turn it on continuously after going off-hook, making it especially convenient for answering telephone calls at night. becomes.
