FIG. 3 shows an electric circuit used in this embodiment. In FIG. 3, a recording and reproducing IC 3
1 has a control circuit 32 and a storage unit 33. The storage unit 33 is a nonvolatile memory. When the storage unit 33 stores data by analog processing, there is almost no electromagnetic interference due to digital processing. Analog recording and playback IC3
For example, Information Storage Devices Inc.
"ISD1210", "ISD1212", one-chip nonvolatile voice recording / playback analog ICs manufactured by
There are “ISD1416”, “ISD1420” and the like. The storage unit 33 may be a digital recording / playback IC. The microphone 34 is, for example, a condenser microphone, and is connected to an input terminal of the control circuit 32. The LED lamp 35 is connected to an LED lamp control terminal of the control circuit 32.

The battery 36 has its negative electrode side grounded and its positive electrode side connected to a positive power supply terminal of the control circuit 32 via a recording power switch 37. Further, the positive electrode side of the battery 36 is connected to the power switch 3 for recording.
7. It is connected to a recording control terminal of the control circuit 32 via a recording prevention switch 38 and a recording switch 39. Here, the recording power switch 37 is, for example, a slide switch. The recording switch 39 is, for example, an ON-OFF push switch, which is turned on when the switch button is pressed, and turned off when the switch button is not pressed. An output volume adjusting volume (variable resistor) 41 is connected to an output terminal of the control circuit 32. A power amplifier 51 is connected so as to amplify the output signal of the volume 41 with power. In addition, speaker 5
3 and 54 are connected so as to be driven by the output signal of the power amplifier 51. The number of the speakers may be arbitrary.

The sensor circuit 42 includes a signal amplifier 43, a comparator 44, a timer 45, and a relay 46. An infrared pyroelectric sensor 47 as a human detection sensor is connected to the input terminal of the signal amplifier 43. The infrared pyroelectric sensor 47 detects infrared rays emitted by a person by the pyroelectric effect. For example, in the case of a differential detection element, it does not respond to stable infrared radiation but responds to a changing input. I do. The pyroelectric effect in this case is a phenomenon in which the surface charge changes when the temperature of the crystal changes due to the incidence of infrared rays. The power supply V _D of the sensor circuit 42 is the battery 3
6 and is connected to a positive power supply terminal of the sensor circuit 42 via a sensor power switch 48.
In the sensor circuit 42, the signal amplifier 43 amplifies the output signal of the infrared pyroelectric sensor 47, and the comparator 44 compares the output signal of the signal amplifier 43 with a reference value. This reference value is a value corresponding to the output signal level of the signal amplifier 43 when the infrared pyroelectric sensor 47 does not detect a person.

When the infrared pyroelectric sensor 47 detects a person, the output signal of the signal amplifier 43 becomes larger than the reference value, so that the output of the comparator 44 becomes high level and the timer 45 is started. At this time, the timer 45
Output becomes high level for a certain period of time.
The relay 46 operates while the output is at a high level. When the relay 46 is operated, the switch of the relay 46 is turned on, since the V _D is applied to the positive power supply terminal of the reproduction control terminal and a power amplifier 51 of the control circuit 32 via the switch of the relay 46, the control circuit 32 and The storage unit 33 enters the reproducing state, and the power amplifier 51 enters the operating state. In this playback state, a signal representing a message stored in the storage unit 33 is applied to the volume 41 via the control circuit 32. Note that the recording and playback IC3
1 ground terminal 31a, sensor circuit section 42 ground terminal 4
2a and the ground terminal 51a of the power amplifier 51 are each grounded. Further, the distance at which the infrared pyroelectric sensor 47 can detect a person (the distance between the person and the election poster 20) can be set arbitrarily. In particular, if a lens (for example, a Fresnel lens) is attached to the sensor hole 13 and the infrared pyroelectric sensor 47 detects a person via the lens, the distance over which the person can be detected can be extended.

With the above configuration, the recording power switch 3
7 and the recording prevention switch 38 are turned on, the recording switch 39 is turned on as a storage control means, so that the voltage of the battery 36 is applied to the positive power supply terminal and the recording control terminal of the control circuit 32, thereby storing and reproducing. The recording and reproducing IC 31 as a means is brought into a storage state. In this storage state, the storage unit 33 of the recording and playback IC 31 stores the message signal input from the microphone 34. In the storage state, the LED lamp 35 is turned on under the control of the control circuit 32. When the recording prevention switch 38 is turned off, the message stored in the storage unit 33 can be prevented from being deleted.

Further, the recording power switch 37 and the recording prevention switch 38 are turned off, and the sensor power switch 4 is turned off.
When the infrared pyroelectric sensor 47 as a human detection sensor detects a person approaching the election poster 20 with the switch 8 turned on, the sensor circuit 4 as a reproduction control means is detected.
2 puts the recording / playback IC 31 into a playback state, the message stored in the storage unit 33 of the recording / playback IC 31 is played, and the speakers 53 and 54 make this message a voice. I can convey this message. When the storable time of the storage unit 33 elapses, the reproduction operation stops. For this reason, the person approaching the signboard can be made to surely recognize the presence of the signboard and the content of this message. In addition, since the reproduction of the message stored in the storage unit 33 is started only when the person approaches the election poster 20, the operation for reproducing the message is not required.

Further, since the infrared detection sensor 47 is used as the human detection sensor, it is possible to easily and reliably detect a person approaching the signboard. In addition, in the said embodiment, the shape of a signboard is not limited to what was illustrated, and may be a cube, a rectangular parallelepiped, a spherical shape, etc. Also, an infrared pyroelectric sensor 47 is used as a human detection sensor,
The invention is not limited to this, and an ultrasonic sensor or the like can be used as a human detection sensor. Further, instead of the battery 36, an AC power source (using an AC-DC converter), a DC adapter, a DC battery, a solar battery, or the like can be used. In addition, a toggle switch or the like can be used as each of the switches. Further, the signboard with a message function according to the present invention is not limited to the poster for election, but may be a signboard for no entry, a sign for no swimming, a warning sign for preventing distress at a ski resort, a signboard for construction, and the like.

[0018]

According to the signboard with a message function according to the first invention of the present application, the contents desired to be conveyed by the signboard can be conveyed to the person from both eyes and ears. For this reason, when the signboard is an election poster, the voice message from the election poster can increase the attention of the person approaching the election poster to the election poster, and the advertising effect of the election can be reduced. Go up. Furthermore, when the signboard is various signs, the advertising effect of the signboard increases, and when the signboard is an off-limits warning board, the warning effect increases, which is useful for disaster prevention. Further, according to the second invention, in addition to the effect of the first invention, the person detecting sensor is an infrared pyroelectric sensor, so that a person approaching the signboard can be detected easily and reliably. For this reason, the effect of the signboard can be made more effective.
