PURPOSE:To decrease the memory capacity of a memory into which voice information is stored by compressing and storing the voice information inputted to an apparatus. CONSTITUTION:A recording and reproducing device RD compresses and stores the voice information inputted from an input section KPC having keys and switches when the input of the voice information is instructed in the input section KBC. The compressed voice information is read out of the recording and reproducing device RD and is outputted in the form of voices in response with the output command from a calculation circuit LSI when the hour and time set at every promise come. The result calculated by the circuit LSI is displayed on a display device DPC.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electronic device that notifies the contents of an appointment by voice when a set time has arrived, for example.

(Explanation and Problems of Prior Art) As is already known, calculators with a clock function and some clocks sound a buzzer or chime when a set time arrives to notify people of the elapsed time or time. It has a function.

However, the buzzer, chime, etc. are used to warn the user of the passage of time or the time itself, but do not inform the user of what it is time to do or what time it is to be notified.

However, for people who are busy every day and meet people or attend meetings, it can be difficult to remember what time it is. In particular, appointments made a week or a month in advance are written down in a notebook, but unless one actively looks at the notebook, they are often forgotten.

Returning to FIG. 2, DPC is a display circuit.

The operation of the embodiment having the above configuration will be explained.

When performing calculations with the equipment of the above embodiment, the switch SW is C

You can view the entered numbers, results, etc. on the instrument DPC.

An example of setting a schedule to call Atsushi Kinoshita now, for example, at 30:30 will be explained.

First, the switch SW is set to the TIME side. Next, enter the memory address where the schedule will be stored. For example, in this embodiment, there are 10 addresses, and the addresses are designated by numerical keys 1 to 0. If the input is at address O, when the numeric key "0" is operated, 0 is stored in the buffer memory of the input circuit INF. Next, record key R
When eC is operated, the counter CNT1 mentioned above increments the value by 1 from the initial state, opens the AND gate G1, and sets "0" stored in the input circuit INF to the counter CNT2. Further, "0" is stored in the register R1 shown in FIG. 4 via the OR gate OR. The "o" stored in register R1 is compared with the contents of register R2 in comparison circuit COMP2. The contents of the register R2 are input by reading the address signal stored on the magnetic tape MT with the magnetic head WRH, via the switch SWI, the amplifier AMP2, and the bandpass filter BPF.

Meanwhile, the operator next sets the scheduled time. For example, perform the following key operations.

rl, r(1, rTIME, r3. rg,
rSET.

The key operation data as described above is 10 when the key rsETJ is operated, the contents of the counter CNTl are further increased by +1, the AND gate G1 is closed, the AND gate G2 is opened, and the input circuit INF is entered. The memory RAM in which the data for 30 minutes is indicated by the counter CNT2
is written to address θ.

Next, the magnetic tape MT rotates, and the part B shown in FIG. 5 represents an address signal, and the information at address 0 is.

When the stored part arrives and the contents of register R1 and register R2 match, the analog switch AS opens and the recording start sound (fifth
(portion C in the figure) is played through the speaker/microphone SAM. The plunger PL is connected to the recording key Rec and the comparison circuit CO.
Switch SWI is switched by the output of AND gate G1, which is opened by the signal with MP, and amplifier AMPI is connected to magnetic head W.
Connect to RH. In this state, microphone and speaker SAM
If you say, ``Call Mr. Kinoshita,'' at the desk, it will be recorded at address 0 on the magnetic tape MT. Next, when the recording button is pressed, the recording button Rec is turned off.

After a predetermined period of time has elapsed, timer TMR outputs a signal, returns counter CNTl to its initial state, and clears register R2, completing the setting operation.

Therefore, the AND gate G4 is opened and the counter CNT1 is incremented by the clock section TC, for example, in minutes.

The schedule is memorized as described above. When the scheduled time is reached, the comparator circuit COMPI compares the clock section TC with the contents of the memory RAM called up by the instruction of the counter CNT2. For example, when the contents of the clock circuit TC reach 10:30, the comparator circuit COMPI indicates a match. A signal is output, and the contents of counter CNT2 at that time are sent to the recording/reproducing device via AND gate G3. The address signals sent as described above are stored in the register R1, and the address signals stored on the magnetic tape MT are read one after another by the magnetic head WRH, input into the register R2, and compared by the comparison circuit COMP2. If they match, the message "Call Mr. Kinoshita" is output from the speaker/microphone SAM following the signal tone P stored on the magnetic tape MT. The schedule contents are stored in the device and retrieved as described above.

[Other Examples]

FIG. 6 is a block diagram showing another embodiment using a semiconductor instead of the magnetic recording described above. To explain the figure, MS is a speaker and microphone, and when the recording key Rec is on, the switch circuit S is set to function as a microphone.
When C is active, it is connected to the converter LPG, and when it is off, it is connected to the synthesizer.

LPG is a converter, which is a circuit that compresses information and converts audio signals into digital signals.

RAM is a memory in which the output of the converter LPG is written. When the recording key Rec is turned on, it is for writing, and when it is off, it is for reading.

syn is a synthesizer that converts the contents of the memory RAM into an acoustic signal, and sends its output to the speaker/microphone MS via the switch circuit SC.

The above operation is performed as follows. In the case of recording, when the recording key Rec numerical keys "1" to "0" are operated as described above, the counter CNT2 is set to that value, and that value is applied as the address of the memory RAMI via the OR gate OR3. Ru. Next, when the time is set, it is stored in the memory RAM as described above.

Next, when the operator speaks into the microphone/speaker MS, the output of the microphone/speaker MS is transferred to the switch circuit SC.
The compressed encoded signal is applied to the converter LPG via the converter LPG, and the compressed encoded signal is stored in the memory RAM.

On the other hand, when the set time is reached and the sound is to be reproduced, an address signal is applied to the memory RAMI via the OR gate OR3, and the memory RAMI is operated to sequentially send out the stored encoded audio signals to the synthesizer syn. The synthesizer syn converts the encoded audio signal into an audio signal again and applies it to the microphone/speaker MS.

(Effects of the Invention) Since the electronic device according to the present invention compresses and stores the input audio information, the storage capacity of the memory for storing the audio information can be reduced.
