Description

Description: TECHNICAL FIELD The present invention relates to an answering machine.

Conventional technology Conventionally, when a power failure occurs in an answering machine during an answering operation, the answering message tape stops at that position, and when power is restored and an incoming call comes from the telephone line, the answering message tape runs from the position where the answering tape stopped due to a power failure. Was.

Also, when the power switch etc. that switches the operation / non-operation of the device in the state of being connected to the power source is switched from OFF to ON, the response message tape is always written regardless of whether the beginning of the response message is cued out or not. There was a thing to cue.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in the conventional answering machine as described above, when a power failure occurs during the sending of the reply message, the reply message tape is stopped in the middle of the reply message. Is restored, and when there is an incoming call in that state, the response message will be played from the middle,
Since the most important part of the response message, such as "Yes, this is XX, but ...", is not sent to the telephone line, the calling party can know where the call came from. There was a problem that it was not possible to leave a message.

In addition, the endless recording tape with a recording time of 30 seconds to 1 minute is often used as the response message tape. If the response message ends in, for example, 20 seconds, what is the remaining portion of the response message? Is a silent part that is not recorded. Therefore, when a power failure occurs during recording of a received message from the caller, the response message stops at the end of the response message, so when the power is restored and there is an incoming call, the response message tape has no sound. Will be played and nothing will be sent to the line. For this reason, since the caller cannot hear anything, it is impossible to confirm whether or not the intended party has been correctly connected, and there is a problem that a message cannot be left.

Also, if the response message tape is always run to the beginning of the response message when the power is turned on to the device, the response message tape will run to the beginning of the response message when the power is restored. When the power switch etc. is turned on while trying to reproduce the received message that has already been recorded in the state where the switch etc. is turned off and the answering machine is in the non-operating state,
First, since the response message tape runs for about 30 seconds to 1 minute, there are problems such as having to wait during this period.
Further, since the tape is driven even when the power is turned on for the first time at the time of purchase, there is a problem that the deck operates without a tape, which gives the user anxiety.

The present invention solves a problem that occurs when a power outage occurs during operation and the power is cut off, and even if a power outage occurs during operation and recovery is performed thereafter, a complete response message to a subsequent incoming call is displayed. When the user turns on the power for the first time or operates the device by operating the power switch, the response message tape is not cued and the desired operation is performed immediately without waiting. It is intended to provide an answering machine that can be operated.

Means for Solving the Problems In order to solve the above problems, the answering machine according to the present invention has a voltage detecting means for detecting an energized state and a switch for switching the operation / non-operation of the answering machine, When the switch is set to non-operation when the voltage detection means detects that it is energized, or when the switch is switched from non-operation to operation when the voltage detection means is detecting energized status. Does not perform the response message tape cueing operation, but has a control means for cueing the response message tape if the switch is set to operate when the voltage detecting means detects that the voltage is turned on. ing.

With this configuration, when the answering machine has a power failure during operation and then returns, the response message tape runs (cues) to the beginning of the response message, and switches from the non-operation state to the operation state when not in the power failure state. When switching is performed, unnecessary cueing operation of the response message tape is prevented.

The operation of the answering machine having the above structure will be described below.

 First, the normal operation will be described.

The power transformer 10 is connected to the commercial power source and the switch
When the switch 19-1 and the switch 19-2 are tilted to the "A" side, the power supply voltage is supplied to each part of the device and is in an operating state. In this state, when the incoming call signal arriving in the telephone line 1 is applied to the incoming call detection means 3, the incoming call detection means 3 outputs the detection signal to the input terminal 16a of the control means 16. Then, the control means 16 outputs a control signal from the output terminal 16b to turn on the line closing means 2 to close the telephone line 1 and to output the output terminal 16b.
Control signals are output from c and 16i to activate the response message recording / reproducing means 7-6, and power is supplied to the motor 8. Therefore, the response message sending means 7 is in the reproduction state, and the response message is sent to the telephone line 1 through the side tone prevention circuit 5 and the low frequency transformer 4. When the transmission of the response message is completed, the response message recording / playback means 7
-6 applies the end signal of the response message to the input terminal 16e of the control means 16. Then, the control means 16 stops the output of the signal from the output terminal 16c, outputs the control signal from the output terminal 16f to activate the received message recording means 6, and records the message from the caller. When the end of the message from the calling party is detected by means not shown,
The control means 16 stops the output of the signal from the output terminal 16f,
Record the response message from the output terminal 16c again and record the response message.
It is applied to the reproducing means 7-6 and the response message tape 7-1 is run. By the way, a conductive foil 7-7 is attached to the response message tape 7-1 so that it comes into contact with the position detecting means 7-3 when it reaches the beginning of the response message. Further, one electrode of the position detecting means 7-3 is grounded, and the other is connected to the input terminal 16g of the control means 16 pulled up by the resistor 17. Therefore, when the response message tape reaches the beginning of the response message, the earth appears at the input terminal 16g of the control means 16. Then, in response to this, the control means 16 stops the output of the control signals from the output terminals 16i and 16b to stop the motor 8, and turns off the line closing means 2 to open the telephone line 1 to open the next incoming call. Prepare for

Next, the transition of the operating state of the answering machine of the present invention will be described with reference to FIGS. 2 and 3. In Fig. 2, the part surrounded by an ellipse shows the state of the device,
The arrow between each ellipse indicates the direction in which the state transitions, and the state transitions in the arrow direction due to the cause written near the arrow.

Positions of interlocking switch 19-1 and switch 19-2,
Also, there are five states as shown in the following table depending on whether the commercial power source to which the power transformer 10 is connected is out of power or the power source is supplied (energized).

First, in state 1, since the switches 19-1 and 19-2 are both on the "B" side and in the off state, and the power source is in a power failure state, the device does not operate. Here, when the power is restored and the power is turned on, the state transits to the state 2. In this state, power is supplied to the device, so power transformer 10, diode bridge
A voltage of 5V is applied to the control means via the capacitor 11, the capacitors 12 and 14, the voltage regulator 13, and the like. At this time, when the voltage rises to a predetermined value, the output of the voltage detection means 15 changes from the logic level "H" level to "L", the control means 16 is released from the reset state, and the state of the switch 19-1 is monitored. start. However, in this state, switch 19-1 and switch 19-1
Since both 19-2 are on the "B" side, they are in a standby state, and no voltage is supplied to the reception message means 6 and the response message means 7, even if an incoming signal comes from the telephone line 1. It is in a so-called off state, which does not respond. If the power fails in this state, it will return to state 1,
Further, in state 2, when the switches 19-1 and 19-2 are switched to the "A" side, the input terminal 16h of the control means 16 changes from the logic level "H" level to "L" and the state 5 (operating state). ). The details of the operation here are as described above. Further, when the switches 19-1 and 19-2 are turned to the "B" side (so-called off) in the state 5, the state returns to the state 2 again and the standby state is set. Switching by turning on / off the normal switches 19-1 and 19-2 is performed between the states 2 and 5.

When the commercial power supply fails in the state 5, the state 3 is entered. At this time, since the power supply voltage decreases from 5V, when the voltage decreases to a predetermined voltage, the output of the voltage detecting means 15 changes from the logic level "L" to "H" and the operation of the control means 16 is stopped. Here, when the power is restored and the power is turned on, the state transits to the state 4. At this time, when the power supply voltage rises to a predetermined value, the output of the voltage detection means 15 changes from the logic level "H" level to "L", the control means 16 is released from the reset state, and the switch
Start monitoring the status of 19-1. However, switch 19-1,
Since 19-2 is already on the "A" side, the control means 16 jumps to the routine of the program for performing the power failure recovery processing, and performs the following processing.

That is, the control means 16 applies a control signal from the output terminals 16c and 16i to the response message recording / reproducing means 7-6 and the motor 8 to drive the response message tape 7-1. When the conductive foil 7-7 attached to the response message tape 7-1 reaches the beginning of the response message along with the tape running, the position detection means 7-3 comes into contact. By the way, as described above, one electrode of the position detection means 7-3 is grounded, and the other electrode is pulled up by the resistor 17 to control means 16
Since the response message tape reaches the beginning of the response message, the input terminal 16g of the control means 16 becomes quiescent. Then, in response to this, the control means 16 stops outputting the control signals from the output terminals 16c and 16i, stops the motor 8, and finishes the cueing of the response message tape. Further, during this time, even if an incoming signal arrives from the telephone line 1, it does not respond.

Status 5 when cueing of response message tape ends
It shifts to (operating state) and waits for an incoming call from the telephone line 1.

When a power failure occurs in the middle of state 4, the state returns to state 3 and when the power returns, the state transits to state 4 again. In state 3, switch 19
When -1, 19-2 is set to "B" side, it transits to state 1 and switches
When 19-1 and 19-2 are set to the "A" side, the state returns to state 3. However, since this transition is the operation of the switch in the state where there is no power supply, there is no change in the operation of the device.

As described above, according to the present embodiment, the response message tape is cued when the power supply is interrupted during operation and then restored, so that a complete response message can be sent even when there is an incoming call after the power is restored. Therefore, when the apparatus is powered on by operating the switches 19-1 and 19-2, it is possible to prevent unnecessary cueing of the response message tape and prevent the user from waiting for this period.

EFFECTS OF THE INVENTION As will be apparent from the above description, the present invention is applicable to the case where the switch is set to the inoperative state when the voltage detecting means detects that the voltage detecting means is turned on, or the voltage detecting means is turned on. If the switch is switched from non-operation to operation while detecting, the response message tape is not cued and the switch is set to operation when it is detected that the voltage detection means is energized. When the power supply voltage is applied, if the power supply voltage is applied and the power supply voltage is applied and the power supply voltage is restored afterwards, Since the response message tape is cued, the complete response message can be immediately reproduced and transmitted at the next incoming call. In addition, since the tape is not cued when the power is turned on for the first time at the time of purchase, the user does not feel uneasy when the deck operates without the tape.
