In this configuration, when a telephone number for calling directory assistance is transmitted from the telephone number transmitting device 6 of the telephone body A ₂ , the transmission signal is input to the input port I ₄ of the MPU 12 directly or through the DTMF discrimination circuit 13 . The process of detecting a telephone number for a directory assistance call and recording it in the MPU 12 will be described below with reference to the flowcharts shown in FIGS. 5 and 6a and 6b. First, step S ₁ in Figure 5.
At this point, the handset _A1 is lifted up, and it is determined whether the switch is on. If it is on, the subroutine Sub1 is processed in step _S2 . The subroutine Sub1 is the process shown in FIG. 6a if the telephone A is a dial type, and the process shown in FIG. 6b if it is a pushbutton type. In the dial type, dial pulses are generated according to each number by turning the dial. First, in step _S7 of FIG. 6a, the dial pulses input to the input port _I4 of the MPU 12 are counted. Next, in step _S8 , it is determined whether this count value matches the first digit number of the telephone number for calling the directory assistance (for example, "1" for "104"). If they match, the dial pulses are counted again in steps S ₉ and S ₁₁ , and in steps S ₁₀ and S ₁₂ , the count value is changed to the second and third digits (“0”) of the telephone number in the directory assistance. , "4"). When the subroutine Sub1 determines that the telephone number is a directory assistance telephone number, the process returns to the main routine, and in step _S3 , the state of the input port _I1 is detected and it is determined whether the recording switch 3 is operated.
If the recording switch 3 is operated, a write control signal is output from the output port O ₄ to the memory 2 in step S ₄ to make the memory 2 ready for writing, and a signal is output to the output port O ₁ . Light up recording display element _L1 .

Next, since the memory 2 has a predetermined storage capacity, if the writing state continues for a long time, the storage capacity may become insufficient. Therefore, in step _S5 , the recording switch 3 is operated to determine whether a predetermined time (for example, 60 seconds) has elapsed after the writing state (recording state), and if the predetermined time has elapsed, the recording operation is automatically ended. do. Next, in step _S6 , in order to determine whether the operator has ended the recording, it is determined whether the recording switch 3 has been operated again, and if the recording switch 3 has been operated again, the write control signal from the output port _O4 is The output is stopped and the write state of the memory 2 is stopped. At this time, the output from the output port _O1 is also stopped and the display element _L1 is turned off.

On the other hand, if telephone A is a pushphone, two different frequencies are mixed and output in response to each button as shown in FIG. Therefore, DTMF discrimination circuit 1
3 to determine these two frequencies and input data corresponding to each frequency to the input port _I4 . 6th
In steps S ₁₃ , S _{15 , and S 17 in FIG} . Determine if it is a number. When the telephone number for directory assistance is determined by this subroutine Sub1, the process returns to the main routine and processes steps _S3 to _S6 .

The recording (storage) operation for the memory 2 is carried out in the same way as in the first embodiment, by inputting the received signal from the directory assistance system generated on the telephone line _VL to the A/D converter 10 through the audio coupling circuit 9 and converting it into a digital signal. do. This digital signal is stored in the memory 2 for a predetermined period of time or until the recording switch 3 is operated again.

Next, the process of reproducing and erasing the contents of the memory 2 will be explained with reference to the flowchart of FIG.

First, in step _S19 , it is determined from the state of input port _I2 that the playback switch 4 has been operated,
If the output port is operated, step _S20
A read control signal is output from _O5 to the memory 2, and the contents related to the telephone number stored in the memory 2 are read out. Also, a signal is output from the output port _O2 to light up the reproduction display element _L2 . Next step
In step _S21 , it is determined whether the reproduction time has elapsed over the time stored in the memory 2, and if it is within this time, it is determined in step _S22 whether the reproduction switch 4 has been operated again. When the storage time has elapsed or when the re-operation of the playback switch 4 is detected, the output from the output ports O ₂ and O ₅ is stopped, reading from the memory 2 is stopped, and the display element L ₂ is turned off. In the reproduction operation in step _S20 , the signal read from the memory 2 is converted into an analog signal by the D/A converter 11, and after being set at a predetermined volume through the Merium VR, it is supplied to the receiver SPa. This allows you to listen to the telephone number answered by directory assistance.

In addition, if the recording switch 3 is not operated in step _S19 , _the input port is
The operation of the reset switch 7 is determined from _I3 , and if the switch 7 is operated, a reset control signal is output from the output port _O6 to the memory 2, and the contents of the memory 2 are cleared (erased). Also, at this time, the reset display element _L3 is turned on. When erasing is completed, the output of the reset control signal is stopped and the display element _L3 is turned off.

Incidentally, when the power switch 14 is turned on, the power display element _L4 to which a signal is output from the output port _O7 lights up.

In each of the above embodiments, a static RAM is used as the recording and reproducing device 2, but a tape recorder or a disk type recording and reproducing device may also be used.

Furthermore, although the embodiment shown in FIG. 4 shows a case in which the device is configured separately from the telephone, the device may be built into the telephone in advance.

The above-mentioned devices are particularly useful for public telephones where notes cannot be taken;
This is effective for receiving phone number inquiries from car phones, etc.
