The operation of the apparatus of the present invention configured as described above will be explained below.

FIG. 3 shows the changeover switch of the control circuit 600 mentioned above.
This is a flowchart showing the operation of the present device when the a-pole is selected in SS (that is, when the signal generation lock mode is selected as described above). The steps will be explained below in the order of block numbers in the flowchart. The operation of the entire device will be easily understood by referring to the circuit diagram of FIG.

(1) When the visitor presses the call button on the intercom slave device, contact PB (address 1) closes and relay R ₁ is activated in the call signal receiving unit 601.
The energized state is self-maintained. This result relay
Each a contact (addresses 2, 3, and 10) of R ₁ becomes "closed," and timer T ₁ (address 3) starts time-limiting operation.

(2) t ₁ second from the start of the operation in paragraph (1) above (e.g.
3.5 seconds) later, the contact point (address 4) of timer _T1 of the first control signal generation section 602 closes, and the first control signal C is sent to section A of the audio generation device 400.
The voltage between RT and T as 1 is given (address 4). As a result, the A section of the audio generating device 400 is
an audio signal V corresponding to the first message mentioned above;
Emit 1. Therefore, the slave interphone device 100 utters, for example, "Dochirasamadesuka" to the visitor via the interphone master device 200. On the other hand, timer T ₁ contact (address 4)
When the timer T ₂ (address 5) closes, the timer T 2 (address 5) starts a time-limited operation and closes the contact point (address 6) of T ₂ after the elapse of the time (for example, 3.0 seconds) until the utterance of the first message ends. Therefore, relay R ₂ (address 6) is energized, and this energization is self-maintained by the a contact of R ₂ (address 7). For this reason R ₂
The b contact (address 4) opens, and the output C1 of the first control signal generating section 602 stops.

(3) When relay R ₂ (address 6) is energized as described above, R ₂ of the first timer circuit 603
The a contact (address 8) closes, and the timer T ₃ (address 8) starts a time-limited operation until t2 seconds (for example, 10.0 seconds).

(4) After timer _T3 starts its time-limited operation in (3) above (that is, after the end of the first message) t2
When a response is received from the visitor before seconds have elapsed and the external lock is in the state: Based on the voice signal of the response from the intercom slave unit 100, the interphone base unit 200 sends a recognition signal to the recognition signal receiving unit 604. R (signal that closes the normally open contact NO (address 10) when receiving an audio signal)
emits. Since the a contact (address 10) of R ₁ is already closed at the stage of (1) above, when the normally open contact NO is closed, relay R ₄ (address 10) is energized, and R ₄
This bias is self-maintained by the a contact (address 11). When externally locked (that is, when the door is locked from the outside), the normally closed contact K ₁ of the reed switch of the signal generating lock 300
is “closed” and normally open contact K ₂ is also “closed” (12
street address). Therefore, when relay _R4 is energized, its a
The contact (No. 13) is closed and the lock status signal receiving unit 6
Timer _T4 of 05 starts time-limiting operation. At the same time, the b contact (address 8) of _R4 opens and timer _T3 is reset.

Note that the operation of the control circuit 600 is similar to that of the signal generating lock 30.
It depends on the signal from 0 when the a-pole or c-pole is selected in the changeover switch SS (address 13) of the operation mode switching unit 606 (that is, the signal generation lock mode described above). When the b pole is selected (i.e., the above-mentioned independent mode), the operation of the control circuit 600 is similar to that of the electric lock 300.
does not depend on the output signal K of R ₄ (13
When the address (address) is closed, the process always advances to the next stage of operation.
In the following, first, the case where the a-pole is selected will be explained.

t3 seconds (e.g. from the time when the visitor responds) to the start of timer _T4 's time-limited operation (i.e. from the time when the visitor responds)
1.5 seconds), the T ₄ contact (address 21) closes. Therefore, the voltage across RT as the second control signal C2 is applied to section B of the audio generating device 400 (address 21). As a result, part B of the voice generating device 400 emits the voice signal V2 corresponding to the second message described above. Therefore, the interphone slave device 1 is connected to the interphone slave device 1 via the interphone master device 200.
From 00 onwards, a voice is uttered to the visitor, for example, ``Tadaimasu desu ga, Hitsuyo ga areba, Onamaeto, Goyou kenwo, Otsushi yatsu teku dasai.'' On the other hand, when the contact point (address 21) of timer T ₄ closes, timer T ₇ (address 22) starts a time-limited operation, and after the time (for example, 7.0 seconds) until the utterance of the second message ends, the timer T ₇ is closed. Close the contact (No. 23). Therefore relay R ₈
(address 23) is energized, _R8 's a contact (address 24)
This bias is self-maintained by. For this reason
The b contact (address 21) of _R8 opens, and the output C2 of the second control signal generator 608 stops. At the same time, _R8 's a contact (address 25) closes and relay _R9 is energized.

(5) When relay R ₉ (address 25) is energized as described above, the third control signal generator 611
_R9 's a contact (address 30) closes. As a result, the recording device 500 is given the RT voltage as the third control signal C3 (address 30).
Therefore, the recording device 500 starts operating. At the same time, the a contact point (address 26) of _R9 of the second timer section 609 closes, and the timer _T8 starts for t4 seconds (for example,
10.0 seconds).

(6) If a response is received by the visitor before t4 seconds have elapsed after timer T ₈ (address 26) starts its time-limited operation in item (5) above (that is, after the end of the second message): The above-mentioned intercom Based on the voice signal of the response from the slave unit 100, the interphone master unit 200 sends a recognition signal R (a signal that closes the normally open contact NO' (address 28) when receiving the voice signal) to the recognition signal receiving unit 610.
emits. Since the a contact of R ₈ (address 28) is already closed at the stage of (4) above, when the contact NO' is closed, the relay R ₁₁ (address 28) is energized, and the a of R ₁₁ is energized.
This bias is self-maintained by the contact (address 29). Therefore, the b contact (address 26) of _R11 is opened and the timer _T8 (address 26) is reset. Above (5)
Timer _T9 , which started the time-limited operation in section 3, closes its contact (address 32) after t5 seconds (for example, 60 seconds).

(7) When timer T ₉ contact (address 32) closes, relay R ₁₂ (address 32) is energized. Therefore, b of R ₁₂
The contact (address 0) opens and the voltage applied to the entire control circuit 600 (voltage between RT and T) is cut off, and the control circuit 6
The entire 00 is returned to its initial state.

(4)′ After timer T ₃ (address 8) starts its time-limited operation in the above (3) (that is, after the end of the first message), t2 remains unanswered by the visitor.
When seconds have elapsed: The contact point (address 9) of the timer T ₃ of the first timer section 603 is closed, and the relay R ₃ (address 9) is energized. As a result, the b contact (address 0) of _R3 opens, and the entire control circuit 600 returns to its initial state.

(4)'' If the visitor responds before t2 seconds have passed after timer T ₃ (address 8) starts the time-limited operation in item (3) above, and the door is locked internally or cannot be accessed from inside or outside. When in the unlocked state: The reed switch contacts of the signal generating lock 300 are either _K1 is "open" and _K2 is also "open" (internally locked state), or _K1 is "closed" and _K2 is "open". "Open"
(both inside and outside are unlocked). Therefore, even if relay R ₄ (address 10) is energized and its a contact (address 13) closes, timer T ₄ does not operate, and the automatic step-by-step operation of the entire control circuit 600 stops at this stage. .

At this stage, a person who has heard the visitor's response from the interphone main device 200 can also have a conversation with the visitor as in the case of a normal interphone device. It is also possible to freely switch the selection switch SS (address 13) to the b pole to set the above-mentioned independent mode and restart the automatic step-by-step operation of the control circuit 600.

(6)′ After timer T ₈ (address 26) starts its time-limited operation in (5) above (that is, after the end of the second message), t4 remains unanswered by the visitor.
When seconds have elapsed: The contact point (address 27) of timer T ₈ of the second timer section 609 is closed, and relay R ₁₀ (address 27) is energized. As a result, the b contact (address 0) of _R10 opens, and the entire control circuit 600 returns to its initial state.

In the above, when the visitor responds to the first message ("Dochira Samadesuka") and the changeover switch SS (No. 13) is set to the c-pole (call operation mode) selection, the device operates as follows. works.

The A contact (No. 13) of relay _R4 closes, and the counting coil of the calling operation signal generating section 607 closes.
CC (address 14) is energized, and the above-mentioned voltage across RT as the ringing operation signal is applied to the chime device CH (address 14). As a result, the preset counter (CC+RC) increments by one, the chime CH sounds, and timer _T5 (address 15) starts its time-limiting operation. A chime sounds during this timed operation. When this time-limited operation ends, the _T5 contact (address 16) closes. Therefore, relay R ₅ (address 16) is energized, its contact (address 17) is closed, and the energization is self-maintained, and at the same time timer T ₆ (address 17) starts time-limiting operation. Also, the b contact of _R5 (address 14) opens and the chime stops. The chime is paused while timer _T6 is running. When the timed operation ends, T ₆
The contact point (number 16) opens. Therefore, relay _R5 is deenergized and the b contact (point 14) of _R5 is closed again.
As a result, the counting coil CC (address 14) is energized again and the count of the preset counter (CC+RC) is further incremented by one. At the same time, chiaim begins to sound. When the above operation is repeated and the count value of the preset counter (CC + RC) reaches a preset value (for example, "3" times), the contact of the coil CC (address 18) closes and the reset coil RC (address 18) is reset. and relay R ₆ (address 19) is activated. As a result, the pret counter is reset and at the same time
_R6 's a contact (address 20) closes. therefore relay
R ₇ (address 20) is energized and R ₇ 's b contact (address 14)
is opened and the paging operation signal generating section 607 is reset. The automatic progression of the operation of the entire control circuit 600 stops here. If those in the room hear the repeated chime and know that there is a visitor, they can press the forced reset switch RS (0 to 0) at any time.
1), reset the control circuit 600, and connect the interphone master unit 200 and the interphone slave unit 1.
00 can be used to talk just like a normal intercom device. Also, without resetting the control circuit 600 as described above, the selection switch SS (13
It is also possible to freely select to set the address (address) to the b-pole (ie, independent mode) selection state and restart the automatic progression of the operations after the above-mentioned (4).

In summary, the device of the present invention, when a visitor presses the call button on the intercom slave 100, utters "Dochirasamadesuka" (for example). Next, if the visitor responds within the specified time, the selection switch will be activated.
When the SS (address 13) is in the a-pole (signal generating lock mode) selection state and the signal generating lock 300 is in the externally locked state, "Tadaimasu desuga, Hitsuyoga areba, Onamaeto, Goyoukenwo, Otsushiya tekudasai" (Example) ). After this utterance, the recording device 500 is operated. Any responses from visitors will be recorded. The selection switch SS is in the signal generation lock mode (A pole) selection state or the calling operation mode (C pole) selection state, and the signal generation lock 300 is selected.
When it is internally locked or unlocked from both the inside and the outside, the movement will stop once after the utterance of "Dochirasamadesuka." In this case, the person at home can make a call as in the case of a normal intercom device, or the selection switch SS can be set to the independent mode (pole B) to control the operation of the control device. It is also possible to restart the automatic step, automatically utter a voice, and record the response. That is, residents generally lock their doors from the outside when they go out, and in this case, the present device operates entirely automatically. When a resident is at home, it is normal to lock the door from the inside or leave it unlocked from both the inside and the outside. After listening to the response, you can freely choose your next action. In some cases, it may be optional to use a resident attendant. In any of the above cases, when the call button is pressed, "Dochirasamadesuka" is automatically uttered, which is effective in preventing crime.

The device of the present invention can also be implemented in the following manner.

FIG. 4 is a circuit diagram showing another example of the third control signal generating section 611 of the control circuit 600 shown in FIG.
In FIG. 4, parts corresponding to those in FIG. 2 are given the same reference numerals. In this example, either the a contact (address 30) of relay R ₉ or the a contact (address 31) of relay R ₁ is selected by selection switch SS' and connected to the circuit to recording device 500. ing. R ₉ side (d pole) at selection switch SS′
is selected, the device operates exactly as in FIG. If the _R1 side (e pole) is selected, the recording device 500 starts operating as soon as the visitor presses the pushbutton switch PB, and the timer
Recording continues for the time set at T ₉ (address 31). In this embodiment, if the selection switch SS' is set to the e side, the visitor can press the push button switch PB.
Since you can record all the audio after pressing , there is a high possibility that you can record the voice of the perpetrator such as a burglary. Also, if the selection switch SS' is set to the d-pole side, only the visitor's name and business information will be recorded, which is beneficial when the capacity of the recording medium (magnetic tape, etc.) in the recording device is limited. be.
