Abstract

PURPOSE:To preclude the possibility of recording an erroneous time due to power failure or wear of a battery or the like by providing a means holding the initial state when a low voltage is detected even if the power supply voltage is recovered. CONSTITUTION:A power supply for a microcomputer 18 is supplied from a battery 25 if a power failure occurs or a commercial power supply is disconnected, and if the battery 25 is consumed, a low voltage detecting means 21 detects it and gives a signal to an initializing circuit 18c. Thus, the initializing circuit 18c initializes a time count section 18b and the count section 18b keeps this state until the time set is conducted even if the power voltage is recovered. Thus, even if an incoming call is received in this state, no erroneous time is recorded and a power failure display is displayed on a time display means 19 while the initializing is being conducted.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an answering machine that automatically answers a telephone call, records a message from the caller, and records the time of arrival.

Conventional configuration and its problems In conventional answering machines that have the function of recording the time of incoming calls on a receiving tape, the time set to 1 o'clock by the timetable is recorded by voice synthesis or other means. Let me say it,
In this known example, a device without a battery for compensating for a power outage in the timetable section can cause the time in the timetable section to be inaccurate during a power outage. First, even if the device is equipped with a power outage compensation battery, if the battery is exhausted, the time on the clock section will no longer be accurate during a power outage. Therefore, when the answering machine operates after a power outage, the wrong time is recorded on the receiving tape, so when the answering machine user later plays back the receiving tape, he or she may record the wrong time on the receiving tape. In view of the shortcomings described above, the present invention has the drawback that the timetable section may not be accurate due to power outages, battery depletion, etc. If the clock goes missing, the user will not have to record the wrong time from now on, and instead of the time, a voice warning, a buzzer sound, or silence will be recorded so that the user can record the reception tape. To provide an answering machine that can recognize an abnormality in a timetable section when playing back, and can prevent erroneous recognition and confusion.

Another object of the present invention is to notify the user that there is an abnormality in the timetable section.
1. To prompt you to reset the time promptly.
, Structure of the Invention In order to achieve all of these objects, the answering machine of the present invention has the following features:
A response means that automatically responds to a telephone call and sends a response message to the telephone line, a message recording means that records the caller's message on a voice recording medium, and a message recording means that records the time or a warning message on the voice recording medium. a voice recording means for recording the time, a time counting means for taking the time as an argument, a low voltage detection means for detecting a drop in the power supply voltage of the time argument means, and an output signal of the low voltage detection means for controlling the time counting means. initialization means for initializing; time setting means for setting the time argument means to a desired time and canceling the initialized state;
Controlling the business message recording means to record the caller's message, and if the time counting means has not been initialized, instructing the voice recording means to record the time, and initializing the time argument means. Not done 1. For example, the control means instructs the voice recording means to record a warning message indicating that the time is abnormal. It is possible to record the time and, if there is an abnormality, to record a warning message or the like to make the user aware of the abnormality.

The output from 17 is input to message recording means 15. Reference numeral 17 is a voice recording means, which has an internal speech synthesis circuit and utters the time and a warning such as "There has been a power outage. Please reset all time settings." 1 and 18 are slave microcomputers. Yes, the second function is
It includes a control section 18a, a time counting section 18b, and an initialization circuit 18c. 19 is a time display means, and the second control section 1
1. The second control section 18a displays the time under the control of the main microcomputer 26, and instructs the audio recording means 17 to output the time and a warning message. Further, the second control section 113a sets the time of the time counting section 18b and cancels the initialization circuit by operating the time setting means 2.degree. Initialization circuit '18b
is detected by the time counter 1 based on the output signal of the low voltage detection means 21.
8b is initialized.

Further, the low voltage detection circuit 21 monitors the power supply voltage of the slave microcomputer 18, and outputs a signal to the initialization circuit 18c when the voltage drops to a voltage that causes an abnormality in the operation at the time of crying. 27 is a commercial power source, and 22 is a constant voltage section that rectifies the commercial power source 27 to make it a constant voltage. 23 and 24 are reverse current prevention diodes for preventing reverse flow of power supply current.

26il-1: This is a microcomputer, and internally includes an output section 26a, an input section 26b, a first control section 26C, and a storage section 26d for storing programs and data. The output section 26a outputs a control signal for switching the relay 16, a control signal for instructing the second control section 18a to issue the time or a warning message, and other control signals for each magnetic tape deck (not shown). Ru. The output of the bell detection circuit and the initialization circuit 18 are input to the input section 26b.
The output signal from c is input.

Next, the operation of the main microcomputer 26 will be explained. FIG. 3 shows the main part of the operation flowchart of the main microcomputer 26.

In step 28, the output signal of the bell detection circuit is monitored, and if a bell is detected, in step 29, the response means 1
4 and sends out a response message. After sending the response message, the relay 16'f is activated in step 30.
: Controlled and switched to the contact 15a side. .

Next, in step 31, the message recording means 1
6 to record the business message 1. When the recording of the business message is finished, the relay 16 is activated in step 32.
is controlled to switch from 1 to b side -\.

Next, in step 33, the signal from the initialization circuit 18c is determined, and if the time divisor has not been initialized to jtJI, the process moves to step 34, and if it has been initialized, the process moves to step 36. Second control section 18a
Instruct the person to say the time.

The second control section 18a controls the sound recording means 17 to record the time, so in step 36, the second control section 18a controls the message recording means 15 to record the time of incoming call. In step 36, since the moeki numeral section 18b has been initialized, the second control section 18a is instructed to generate a warning sentence, and in step 37, the warning sentence is recorded. The operation will be explained focusing on Ichiyo 18. As shown in FIG. 2, power for the slave microcomputer 18 is supplied from a constant voltage section 22 via a diode 23 and from a power failure compensation battery 25 via a diode 24. Normal commercial power supply 26
is connected, the voltage output from the constant voltage section 22 is set higher than the voltage J:9 of the power failure compensation battery 25, so the power failure compensation battery 26 is not consumed.

Power outage 11! 4 and commercial power cut off 11! Since power for the slave microcomputer 18 is supplied to the power outage compensating battery 26, time counting can be continued and accurate time counting can be guaranteed.

However, if this battery 26 becomes exhausted, the accurate operation of the slave microcomputer 18 cannot be guaranteed1.
Here, the detection voltage 1L of the low voltage detection means 21 is set to the lowest possible voltage within the range that can guarantee the accurate operation of the slave microcomputer 18.
When the battery 26 is depleted and the voltage drops below this level, a signal is output to the initialization circuit 18ci'. Initialization circuit 18
c initializes the time counter 18b upon receiving the signal.

Furthermore, this initial jυ1 conversion circuit 18c once operates as a time counter 18.
When B is initialized, the commercial power supply is connected and the initialized state is maintained even if the power supply voltage recovers, and it is not canceled in J, where the time is set. Therefore, if the power supply voltage is restored and there is an incoming call while in this initialization state, 1/Ci, J:, the main microcomputer 26 will always enter step 36 from step 33 and record the erroneous /ζ time. Never.

While the second control section 18a is being initialized, a power failure is displayed on the time display means 19 to visually prompt the user to set the correct time.

As described above, there is a bell detection circuit for detecting all the ringing signals generated on the telephone line, a response means comprising a response message tape, a reproduction magnetic head, and an amplifier, a message recording tape and a recording magnet. A message recording means comprising a head and an amplifier, a relay for switching recording of the message and the time or a caution message, a slave microcomputer comprising a second control section, a time counting section, an initialization circuit, and a time recording means. The display means, the time setting means, the low voltage detection means, the constant voltage unit that makes the commercial power supply constant voltage, the battery for compensating for power outages for the time stamp, and the entire operation as an answering machine t fli! By being equipped with a main microcomputer that controls I, in the event of a power outage or when commercial power is cut off, the battery for power outage compensation will be exhausted,
Alternatively, if the battery is not completely consumed but has been consumed for a long time due to a power outage, etc., by initializing the time divider, the power will be restored and the next time an incoming call will occur, the incorrect time will be displayed. Since the entire warning message is recorded without recording the entire message, the user will not be confused or misrecognize the time of incoming call.

Furthermore, if the user plays back the business message tape and a warning message is recorded, the user can recognize that it is necessary to set the time, change the power outage compensation battery, etc. The user can also recognize the same thing as above by looking at the power outage display on the time display means 1. In this embodiment, magnetic tape is used for the response means 14 and the message recording means 15. But, oh...
+1. is a speech synthesizer or digital recording/playback device t<i
etc. may also be used.

If the control means instructs the voice recording means to record a warning message, etc. indicating that the time is abnormal, By initializing the time counting means when the battery is completely exhausted, when the power is restored and the next time an incoming call is received, the time will not be recorded by mistake, and the message will not be recorded. Since the message is recorded, when the user later plays back the message tape, there is no need to misrecognize the incoming time or cause confusion, and there is no need to reset the time or replace the battery. This provides an answering machine that allows you to know certain things, and its effects are great.
