Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to an answering machine that can be remotely controlled.

[Prior Art] Conventionally, an answering machine has been used in various places to record the contents of an incoming call when absent. This device is also proposed to have a remote control function so that the recorded contents can be heard from the destination. This is when you call an answering machine from a destination and send a command signal through the telephone line,
The answering machine which receives the command signal reproduces the recorded contents and transmits the recorded contents.
In this case, the answering machine that receives the command signal sends an effective tone when the command signal is correctly received, and sends an error tone when the command signal is not received correctly.

[Problems to be Solved by the Invention] However, when an error tone is transmitted, there is a problem that the operator does not know whether the cause is an operation error by the operator or a tone reception error.

[Means for Solving the Problem] In order to solve such a problem, a first invention is a voice synthesizing circuit which sends a voice confirmation signal representing a command content to a telephone line in response to a received command signal, and an effective voice synthesizing circuit. A tone signal generating circuit for selectively generating a tone signal and an error tone signal, and a determining means for determining whether the received command signal is valid or not and controlling the operation of the tone signal generating circuit are provided. is there.

In the second invention, the tone signal generating circuit is provided with a function of generating an end tone when the last remote operation is completed, and the command signal receiving operation is permitted only during the operation when the end tone is generated. And a line control means for opening the telephone line when the operation of the timer ends.

[Operation] According to the first invention, a voice notification of what the received command signal looks like is transmitted, and both information indicating whether or not the command signal has been correctly received is transmitted. A second invention is that when a remote control operation ends, a tone indicating the end of the operation is sent, a timer for receiving a command signal next operates, and if a command signal arrives again during the operation of the timer, The remote control for the command is performed, and if the command signal does not arrive, the operation ends due to the timeout of the timer, and the line is opened.

[Embodiment] FIG. 1 is a block diagram showing an embodiment of an apparatus configured by applying the present invention. In the figure, 1 ₁ and 1 ₂ are diodes, 3 _{1 to} 3 ₁₀ are capacitors, 4 ₁ and 4 ₂ are hook switches,
5 ₁ and 5 ₂ are transistors, 6 is a click detection circuit, 7 is a call circuit, 8 is a dial circuit, 9 is a push button dial,
Reference numeral 10 is a hold sound generating circuit, 11 is an amplifier, 12 is a speaker, 13 is a voice recording / reproducing circuit, 14 is a CPU, and 15 is a function key.

FIG. 2 is a flowchart showing the operation of this device.
This device sends a response message (may be a tone signal) as shown in step 100 after answering, and receives an ID code in step 101. This ID code consists of an * (asterisk) code and a 4-digit numerical code. The ID code is received in step 101,
If it does not match the registered ID code in step 102, it is determined in step 103 whether or not the number of mismatches is 3, and in step 104 it is determined whether or not a certain time has elapsed. If neither of the steps 103 and 104 is applicable, an ID code reminder sound is transmitted in step 105 and the process returns to step 100. When either of the conditions of step 103 or 104 is satisfied, an error sound is transmitted as shown in step 106, but it is possible to record the message.

When the ID signal received in step 102 matches the ID code registered in advance, a reception sound is sent out as shown in step 108, and the command reception state is entered as shown in step 109.

FIG. 3 is a flow chart showing the CPU operation after the command reception state in step 109. In step 200, the remote controller termination judgment timer (in this embodiment, the timer operation time is 20 seconds) is started. And step
After it is determined in step 201 whether or not this timer has expired, the command input is determined in step 202, and the command is registered in the general answering machine as shown in step 203. It is determined whether or not. If it is such a registration command, the voice guidance of the command is given as shown in step 204. This voice guidance uses voice synthesis so that a voice confirmation signal for the command signal received by the CPU 14 is generated.
Control IC20.

Next, in step 205, it is determined whether the above-mentioned registration command is preset in the own device and is therefore a valid command for the own device.
It is judged by. As a result, the CPU 14 selectively generates an effective tone signal or an error tone signal, and sends the tone signal by the route shown by the thick line in FIG. Therefore, if it is a valid command, step 20
As shown in 6 to 208, the effective tone is transmitted, the operation corresponding to the acceptance command, and the end tone are transmitted.

That is, when the remote control operation immediately before step 208 ends, a tone signal indicating the end of the operation is generated. Then, the flow returns to step 200, the remote controller end determination timer is started again, and the command signal can be accepted during the operation period of the timer. If a command signal arrives again during this period, the same operation as described above is performed, but if the command signal does not arrive, step 201 determines that the timer has timed out, and
As shown by 210 and 211, processing of error tone transmission and line release is performed.

On the other hand, if the command is not a valid command at step 205, an error tone is transmitted as shown at step 209.

[Effects of Device] As described above, the first device sends the voice confirmation signal in response to the command signal, so that the operator can know the operation content of the operator received by the answering machine. Even if an error tone is sent, it is possible to recognize whether the operation is mistaken or the reception error, so that it is possible to perform a reliable operation. In the second invention, the end of the remote control operation is notified by a tone, and the timer is activated when the tone is generated, and the next command signal can be received during the operation of the timer, so that the command can be received multiple times. Moreover, since the line is opened when the operation time of the timer expires, necessary remote control operations can be sequentially performed, and the line is opened when the necessary remote control ends.
