[0003]

In the above-mentioned conventional information guiding apparatus, since the reach of radio waves is relatively large, as shown in FIG. If there is an exhibit B, the individual exhibit A,
When the position information providing area 1 of the exhibit A and the position information providing area 2 of the exhibit B are defined by installing the radio wave transmitters for each B, the signals transmitted from the radio wave transmitters will interfere with each other in the interference occurrence area 50. However, there is a problem in that it is difficult to separate information guides for adjacent exhibits due to the possibility of duplication. In addition, the interference occurrence area 50
However, there is a problem in that the radio wave receiver may generate noise and make a visitor uncomfortable. On the other hand, by using infrared light instead of radio waves, an infrared light transmitter is installed for each exhibit and the infrared light emitted from the infrared light transmitter is received by the infrared light receiver. Some of them provided information by receiving the same information, but because the reach of infrared light was relatively small, when installing in a wide information providing area, multiple infrared light transmitters There was a problem that it was necessary to arrange them individually.

[0004]

It is an object of the present invention to combine a wide range of information provided by radio waves with a narrow range of information provided by infrared light so that a plurality of information providing areas can be provided in both a wide range and a narrow range. An object of the present invention is to provide an information guidance device that can transmit information guidance without interference.

Corresponding to the (Germany) language, the third class guidance information 1G to the third class guidance information NG are stored in a storage area for each address different from the first class and the second class.

In the voice information storage means 30, the languages of a plurality of countries can be switched by a language switch provided on the case. This language changeover switch is transferred from the reproduction control circuit section 23 described later by being arbitrarily changed to a language desired by the visitor by the museum or the staff of the museum or a visitor who has received the information guide receiver 4. The position information signal is switched to the storage area for each country of the voice information stored in the voice information storage means 30.

In addition, the reproduction control circuit section 23 of the information guide receiver 4 preselects a storage area for each country of the voice information storage means 30 by switching the language changeover switch, and also receives the radio wave position information signal receiving means. 27 corresponding to the position information signal used in the wide range addressed by the first decoder 18 and the position information signal used in the narrow range addressed by the second decoder 22 of the infrared light position information signal receiving means 28.

At this time, if Japanese is selected by the language selection switch, Japanese guidance information corresponding to the address signal of the exhibit is selected in the Japanese information storage area, and German is selected by the language selection switch. Then, the guidance information in German corresponding to the address signal of the exhibit is selected in the storage area for German information.

Then, in the reproduction control circuit section 23, the information guide receiver 4 is provided with the first decoder 18 of the radio wave position information signal receiving means 27 within the radio wave area of the radio wave position information transmitter 2.
When addressing a position information signal for use in a wide range, the infrared light position information signal receiving means 2 enters the infrared light area as the visitor moves,
When the position information signal for use in a narrow range is newly addressed by the second decoder 22 of No. 8, the position information signal addressed by the first decoder 18 in the radio wave area is discarded, and in the infrared light area. The second decoder 22 has a function of calling the address, giving priority to the position information signal, and transferring the guide information in the sound information storage means 30 to the sound reproducing unit 24 in response to the position information signal.

The transmitters 3a, 3b, 3c are separately installed on the ceiling near the exhibits A, B, C, respectively. When the radio wave position information transmitter 2 is turned on, the radio wave position information signal having the information guide of the first floor forms a radio wave area D, and the infrared light position information transmitter 3 is turned on to the exhibits A and B. The infrared light area 1, the infrared light area 2, and the infrared light area 3 are formed around the exhibit C by individual infrared light position information signals.

The information guide receiver 4 is held by the visitor at the reception desk, and its operation is started when the power switch is turned on. When entering the radio wave area D in the room on the floor, the radio wave position signal receiving means 27 receives the radio wave position information signal by the receiving antenna 15, and the first decoder 18 extracts the radio wave position information signal from the radio wave position information signal 0001 of the voice information storing means 30. The address (1st floor) is called up and the guide information of the address 0001 is reproduced by the voice reproducing unit 24.
Since the information is transferred to, the reproduction device 26 provides the information guidance in German corresponding to the first floor to the observer.

When the information guide of the first floor in German is being reproduced for the visitor, when the visitor moves on the first floor and approaches the exhibit A and enters the infrared light area 1. The infrared light position signal receiving means 28 receives the infrared light position information signal, and the second decoder 22 calls the address 0010 (exhibit A) from the infrared light position information signal. The circuit section 23 has a radio wave area D.
In step 1, the radio wave position information signal addressed by the first decoder 18 is discarded, the infrared light position information signal addressed by the second decoder 22 is prioritized, and the voice information storage means is associated with this position information signal. Three

After that, when the visitor leaves the exhibit A and exits from the infrared light area 1 of the exhibit A, the radio wave area D
In order to enter the inside, the radio wave position signal receiving means 27 receives the radio wave position information signal by the reception antenna 15, and the first decoder 18 addresses the radio wave position information signal to the address 0001 (1st floor) of the voice information storing means 30. By being called and the guide information at the address 0001 is transferred to the voice reproducing unit 24, the reproducing device 26 provides the observer with a wide area information guide in German corresponding to the first floor.

Then, when the visitor further moves, exits the radio wave area D, approaches the exhibit B, and enters the infrared light area 2, the infrared light position signal receiving means 28 causes the infrared light position information to be received. Since the signal is received and the second decoder 22 calls the address 0011 (exhibit B) from the infrared light position information signal, the reproduction control circuit unit 23 addresses the radio wave area D by the first decoder 18. The called radio wave position information signal is discarded, and the second decoder 22
The infrared light position information signal called by the address is given priority, and the guidance information (guidance information 2G) at the address 0011 of the voice information storage means 30 is transferred to the voice reproduction unit 24 in response to this position information signal, and thus reproduced. The information guide in German corresponding to the exhibit B is provided to the observer by the device 26.

As described above, the information guide receiver 4 moves from the radio wave area of the radio wave position information transmitter 2 to the infrared light area of the infrared light position information transmitter 3 with the visitor, or vice versa. Further, even if the infrared light position information transmitter 3 moves from the infrared light area to the radio wave position information transmitter 2, the single voice guidance information signal is reproduced.

The sixth amplifier 37 of the radio wave information guide transmitter 31a amplifies the power level of the high frequency signal containing the individual voice guide information to achieve impedance matching with the transmission antenna 38 which will be described later.

Transmission antenna 1 of radio wave information guide transmitter 31a
0 radiates a high frequency signal containing individual voice guidance information into the air.

Since the radio wave information guide transmitter 31a is arranged on the ceiling of each floor in a building such as a museum, a radio frequency signal including individual voice guide information is transmitted from a ceiling to a floor surface in a relatively wide range of radio waves. Radiates into the area.

The second voice information storage means 39 of the infrared light information guide transmitter 31b stores a plurality of voice guide information in a predetermined individual storage area.

The infrared light emitting diode emits an optical signal including the individual voice information guide signal into the air by applying the individual voice information guide signal amplified by the seventh amplifier 42 as a forward bias voltage.

Since the infrared light information guide transmitter 31b is arranged on the ceiling close to each exhibit in a building such as a museum, the infrared light guide transmitter 31b is an optical signal including an individual code signal for each exhibit from the ceiling to the floor. Emits the signal in a relatively narrow infrared light area. Since the infrared light has directivity, the infrared light area formed by this infrared light is in a range smaller than the radio wave area of the radio wave information guide transmitter 31b described above.

On the other hand, the reception antenna 44 built in the information guide receiver 4 has a high frequency including an individual voice information guide signal in the radio wave area formed by the emission of the transmission antenna 38 of the radio wave information guide transmitter 31a.

Reference numeral 7 is a photodiode that is attached to the upper side of the case, that is, at a position facing the ceiling of the building, and that excites electrons corresponding to the energy of the light with which the light receiving portion is irradiated and converts the electrons into an electric signal. When the light receiving element 47 receives an optical signal including an individual voice guidance information signal within the infrared light area formed by the light emitting element 43 of the infrared light information guide transmitter 31b, the individual voice guidance is received. It is converted into an electric signal containing an information signal and transferred to the ninth amplifier 48.

The ninth amplifier 48 built in the information guide receiver 4 amplifies the power level of the electric signal including the individual voice guide information signal transferred from the light receiving element 47, and the amplified individual voice guide information. The electric signal including the signal is transferred to the input signal control circuit 49 described later.

Input signal control circuit 49 of information guide receiver 4
When the voice guidance information signal used in the wide range extracted from the first voice information storage means 32 is transferred by the first data serial converter 34 of the radio information guidance transmitter 31a, the transferred radio information guide is transmitted. The voice guidance information signal from the transmitter 31a is transferred to a voice reproducing unit 50, which will be described later, and is taken out from the second voice information storage means 39 by the second data serial converter 41 of the infrared light information guidance transmitter 31b. When the voice guidance information signal used for the individual exhibit is transferred, the transferred voice information guidance signal from the infrared light information guidance transmitter 31b is transferred to the voice reproducing unit 50 described later.

Further, the input signal control circuit 49 is provided when the information guide receiver 4 receives a voice guide information signal for use in a wide range from the receiving antenna 44 in the radio wave area of the radio wave information guide transmitter 31a. , A voice guidance information signal for use in a narrower range than the light receiving element 43 within the infrared light area of the infrared light information guidance transmitter 31b is newly received as the visitor moves. Then, in the radio wave area, the radio wave information guide transmitter 31
A voice guidance information signal used for a wide range which has been received from a is discarded, and the voice guidance information signal for each exhibit received from the infrared light information guidance transmitter 31b in the infrared light area is given priority, and this exhibition is displayed. It has a function of transferring only the voice guidance information signal for each object to the voice reproducing unit 50.

Since the voice guidance information signal transferred from the input signal control circuit 49 is a digitized signal, the voice reproducing section 50 of the information guidance receiver 4 converts this digital signal into a voice signal by analog conversion. This audio signal is transferred to the tenth amplifier 51 described later.

Tenth amplifier 51 of information guidance receiver 32

In the information guide 1 as described above, the radio wave information guide transmitters 31a are installed on the ceilings of the respective floors of the building, and a plurality of infrared light information guide transmitters 31b corresponding to the number of exhibits are displayed. They will be installed separately on the nearby ceiling. When the radio wave information guidance transmitter 31a is turned on, a radio wave area is formed by the voice guidance information signal of each floor,
When the infrared light information guide transmitter 31b is turned on, an infrared light area is formed around each exhibit by an individual voice guide information signal.

The information guide receiver 32 is held by a visitor at the reception desk, and its operation is started when the power switch is turned on. When the visitor enters the room on the first floor, it enters the radio wave area. The receiving means 32 receives a voice guidance information signal to be used in a wide range by the reception antenna 44, and provides a wide area information guidance corresponding to the first floor to the observer by the regenerator 52 via the voice reproducing section 24.

While the wide area information guide corresponding to the first floor is being reproduced for the visitor, when the visitor moves on the first floor and approaches the exhibit and enters the infrared light area. Since the information guidance receiving means 32 receives the voice guidance information signal for a narrow range from the light receiving element 47, the information guidance receiving means 32 discards the voice guidance information signal used in the wide area which has been received in the radio wave area and receives it from the light receiving element 47. By prioritizing the voice guidance information signal for the narrowed range and transferring only this voice guidance information signal to the voice reproducing unit 50, the information guidance in the wide area corresponding to the first floor is interrupted and displayed from the reproducing device 52. Individual information guidance corresponding to the object A will be provided to the observer.

After that, when the visitor leaves the exhibit and exits from the infrared light area of the exhibit, the information guide receiving means 32 receives the voice guide information signal by the receiving antenna 44 because it enters the radio wave area. Then, by being transferred to the audio reproduction unit 50, the individual information guide corresponding to the exhibit A is switched to the wide area information guide corresponding to the first floor and reproduced by the reproducer 52 to the observer. Becomes

As described above, the information guide receiver 32 is
Move with the observer from the radio wave area of the radio wave information guide transmitter 31a to the infrared light area of the infrared light information guide transmitter 31b, or conversely, move to the infrared light area of the infrared light information guide transmitter 31b. Even if it moves from the radio wave information guidance transmitter 31a to the radio wave area, only a single voice guidance information signal is reproduced.

FIGS. 6 and 7 show a third embodiment of the information guiding apparatus according to the present invention.

In the information guiding device 1 shown in FIG. 6, only the information guiding receiver 4 which is the information receiving unit 1B is shown, and the radio wave information guiding transmitter and the infrared light information guiding transmitter are the second embodiment. Therefore, the same reference numerals as those in the second embodiment are used for the description.

The information guide receiver 4 in this case is to be rented to a visitor and is housed in a handy type case, and a power switch (not shown) is provided outside the case for reception. The antenna 44, the eighth amplifier 45, the demodulator 46, the light receiving element 47, the ninth amplifier 48,
The input signal control circuit 49, the audio reproduction unit 50, the tenth amplifier 51, and the reproduction device 52 are built in, and the input signal control circuit 49
Is provided with an output stop circuit 53.

Further, in the first voice information storage means 32 of the radio wave information guide transmitter 31a, voice guide information for each exhibit is stored in a predetermined storage area, and infrared light information guide transmission is carried out. No voice is stored in the second voice information storage means 39 of the machine 31b.

As shown in FIG. 7, such an information guide receiver 4 is arranged on the ceiling near each of the exhibits A and B where the radio wave information guide transmitter 31a is relatively distant from each other. The guidance transmitter 31b is used for each radio wave information guidance transmitter 3
By being placed on the ceiling at a position where the radio wave areas of 1a overlap, the radio wave area (information providing area) 1 of one radio wave information guide transmitter 31a is formed around the exhibit A, and around the exhibit B. The other radio wave information guide transmitter 31a
The radio wave area (information providing area) 2 is formed, and the radio wave area 1 and the radio wave area B coincide with the radio wave interference area and the infrared light area (infrared light transmission) of the infrared light information guide transmitter 31b. Area) E is formed.

Then, the input signal control circuit 49 of the information guide receiver 4 uses the first data serial converter 34 of the radio wave information guide transmitter 31a to cause the first voice information storage means 3 to operate.
When the voice guidance information signal used in a wide range taken out from No. 2 is transferred, the transferred voice guidance information signal from the radio wave information guidance transmitter 31a is transferred to the voice reproduction unit 5 which will be described later.
Along with the transfer to 0, the second data-to-serial converter 41 of the infrared light information guide transmitter 31b transfers the voice guide information signal to be used for the individual exhibit taken out from the second voice information storage means 39. Then, the transferred voice information guide signal from the infrared light information guide transmitter 31b is transferred to the voice reproducing unit 50.

Further, the input signal control circuit 49 receives the voice guidance information signal to be used by the information guidance receiver 32 from the receiving antenna 44 in the radio wave area of the radio wave information guidance transmitter 31a for use in an individual exhibit. When the observer moves, the infrared light area enters the infrared light area and the light receiving element 43 receives the infrared light in the infrared light area of the infrared light information guide transmitter 31b. 53
By the radio wave information guide transmitter 31 within the radio wave area
Both the voice guidance information signal used for the individual exhibit received from a and the voice guidance information signal (silent) received from the infrared light information guidance transmitter 31b in the infrared light area are voiced. It is not transferred to the reproducing unit 50.

As a result, the visitor moves and exhibits A
When approaching the radio wave and entering the radio wave area 1, the information guidance receiver 4
Reproduces the individual voice guidance information of the exhibit A received by the reception antenna 44, and then the visitor goes from the exhibit A to the exhibit B, and the infrared rays are displayed at approximately the middle of the exhibits A and B. When entering the light area E, the information guide receiving means 32
Is not reproduced by the regenerator 52.

As described above, in the information guide device 1 in this case, the information guide receiver 4 and the visitor are in the radio wave area of the radio wave information guide transmitter 31a and the radio wave area of the radio wave information guide transmitter 31a. If it enters the range where the radio wave area of another radio wave information guide transmitter 31a which is close to the radio wave overlaps, it will enter the infrared light area of the infrared light information guide transmitter 31b. The signal reproduction is stopped so that the noise reproduction is not performed in the radio wave area where interference occurs.

[0086]

As described above, according to the information guiding apparatus of the first aspect of the present invention, the infrared light information transmitting unit is arranged in the radio wave area of the radio wave information transmitting unit. When the information receiving unit receives an individual radio wave information signal within the radio wave area of the radio wave information transmitting unit, it reproduces one of the information corresponding to the radio wave information signal,
When entering the infrared light area of the infrared light information transmission unit, the sound information corresponding to the radio wave information signal is not reproduced, and the sound information corresponding to the infrared light information signal can be switched to the reproduction.
Even if the information receiving unit passes through a plurality of information providing areas, it receives only a single code signal and does not receive a mixed code signal. By using the information guidance corresponding to the narrow range by light together, the information guidance can be transmitted in the wide range and the narrow range without interference. According to the information guiding apparatus of the second aspect of the present invention, the infrared light information transmitting unit is arranged in the radio wave area of the radio wave information transmitting unit. When the information receiving unit receives an individual radio wave information guide signal within the radio wave area of the radio wave information transmitting unit, it converts the radio wave information guide signal into sound and reproduces it, but within the infrared light area of the infrared light information transmitting unit. When the signal enters, the radio wave information guide signal is not reproduced, but the infrared light information guide signal is switched to reproduction, so that the information receiving unit can output only a single voice information guide signal even if it passes through a plurality of information providing areas. It does not receive the voice information guidance signal that has been interfered with by receiving the information, and by combining the information guidance corresponding to a wide range by radio waves and the information guidance corresponding to a narrow range by infrared light, Information guidance can be transmitted without interference even in. According to the information guiding apparatus of the third aspect of the present invention, the infrared light information transmitting unit is arranged in the radio wave area of the radio wave information transmitting unit. When the information receiving unit receives an individual radio wave voice information guide signal within the radio wave area of the radio wave information transmitting unit, the information receiving unit converts the radio wave voice information guide signal into sound and reproduces it. Once inside, neither the infrared light voice information guide signal nor the radio wave voice information guide signal is reproduced, so the information receiving unit does not reproduce noise even when it comes to a place where the radio wave areas overlap. By combining the information guidance corresponding to a wide range by radio waves and the information guidance corresponding to a narrow range by infrared light, the information guidance can be transmitted in a wide range and a narrow range without interference. According to the information guiding apparatus of the fourth aspect of the present invention, the infrared light information transmitting unit is arranged in the radio wave area of the radio wave information transmitting unit. When the radio wave information receiving unit receives an individual radio wave information signal within the radio wave area of the radio wave information transmitting unit, the information receiving unit receives one of the voice information stored in the voice information storage unit in correspondence with the radio wave information signal. When the individual infrared light information signal is received within the infrared light area of the infrared light information transmission unit, the sound information corresponding to the infrared light information signal is reproduced and the sound corresponding to the radio wave information signal is reproduced. Since the information is reproduced with priority, and the voice information corresponding to the radio wave information signal is not reproduced, the information receiving unit does not reproduce the information even if it passes through a plurality of information providing areas in the same manner as in claim 1. By receiving only one code signal and not receiving a code signal that has been interfering, by combining the information guidance corresponding to a wide range by radio waves and the information guidance corresponding to a narrow range by infrared light, a wide range can be obtained. Can also transmit interference information without assistance in a narrow range. Claim 5 of this invention
According to the information guide device of the above, the infrared light information transmission unit is arranged in the radio wave area of the radio wave information transmission unit. When the information receiving unit receives an individual radio wave information guide signal within the radio wave area of the radio wave information transmitting unit, the input signal control circuit outputs a voice reproduction signal corresponding to the radio wave information guide signal to reproduce by the regenerator. However, when it enters the infrared light area of the infrared light information transmission unit, the input signal control circuit does not output the sound reproduction signal corresponding to the radio wave information guidance signal, but reproduces the sound corresponding to the infrared light information guidance signal. Since only the signal is output, the audio reproduction signal corresponding to the infrared light information guide signal is reproduced by the reproducer, so that the information receiving unit passes through the plurality of information providing areas in the same manner as in claim 2. Even if it receives only a single information guidance signal and does not receive an information guidance signal that has been mixed, it does not receive information guidance that corresponds to a wide range by radio waves and information that corresponds to a narrow range by infrared light. By combining the inner can also transmit interference information without assistance in a narrow range even in a wide range. According to the information guiding apparatus of the sixth aspect of the present invention, the infrared light information transmitting unit is arranged in the radio wave area of the radio wave information transmitting unit. When the information receiving unit receives an individual radio wave information guide signal within the radio wave area of the radio wave information transmission unit, the input signal control circuit section outputs a voice reproduction signal corresponding to the radio wave information guide signal to reproduce by the regenerator. However, when it enters the infrared light area of the infrared light information transmission unit, the input signal control circuit outputs the sound reproduction signal corresponding to the radio wave information guidance signal and the sound reproduction signal corresponding to the infrared light information guidance signal. Therefore, the information receiving unit is configured so that neither the audio reproduction signal corresponding to the radio wave information guide signal nor the audio reproduction signal corresponding to the infrared light information guide signal is reproduced by the reproducer in order to stop the information reception unit.
In the same manner as above, noise will not be reproduced even when it comes to a place where the radio wave areas overlap, and by using the information guidance corresponding to a wide range by radio waves and the information guidance corresponding to a narrow range by infrared light together. , Information guidance can be transmitted in a wide range and a narrow range without interference.
According to the information guiding apparatus of the seventh aspect of the present invention, the infrared light information transmitting unit is arranged within the radio wave area of the radio wave information transmitting unit. When the information receiving unit receives the individual code signal by the receiving antenna within the radio area of the radio information transmitting unit, the reproduction control circuit unit corresponds to the code signal among the voice information stored in the voice information storage unit. When the information receiving unit receives an individual code signal by the light receiving element within the infrared light area of the infrared light information transmitting unit, the reproduction control circuit section reproduces the one at the address The coded signal is processed in preference to the individual coded signal received by the receiving antenna,
Since the audio information corresponding to the individual code signals received by the receiving antenna is not reproduced, the information receiving unit
Similarly to claim 1 and claim 4, even when passing through a plurality of information providing areas, only a single code signal is received and an interference code signal is not received. By using both the corresponding information guidance and the information guidance corresponding to a narrow range by infrared light, the information guidance can be transmitted in a wide range and a narrow range without interference. According to the information guiding apparatus of the eighth aspect of the present invention, the infrared light radio wave information transmitting unit is arranged in the radio wave area of the radio wave information transmitting unit. When the information receiving unit receives the radio wave information guide signal by the receiving antenna within the radio wave area of the radio wave information transmitting unit, the input signal control unit reproduces the voice information carried in the radio wave information guide signal, When the infrared light information guide signal is received by the light receiving element within the infrared light area of the information transmission unit, the input signal control section gives priority to the infrared light information guide signal over the voice information carried in the radio wave information guide signal. Since the voice information carried is reproduced and the voice information carried in the radio wave information guide signal is not reproduced, the information receiving unit has a plurality of pieces of information in the same manner as in claims 2 and 5.
