Description

  The present invention relates to an olfactory display, and more particularly, to an olfactory display that presents a scent within a limited range of time and space.

  In recent years, various olfactory displays that present scents (olfactory information) in conjunction with audiovisual displays such as televisions and personal computers have been proposed for the purpose of presenting information that gives users a high sense of realism and high immersive feeling. . Here, when it is desired to present a certain scent for a certain period of time, the scent is simply diffused into the space. However, for example, in order to present a scent in accordance with the change of the scene of the content presented by the audiovisual display, temporal control (temporal locality) of the scent presentation is required. Further, for example, in order to present a scent only to a target person, spatial control (spatial locality) of scent presentation is required. Furthermore, if the temporal and spatial locality of the scent presentation is realized, the fragrance used can be saved greatly, and the problem of the remaining scent can be solved. For these reasons, there is a demand for an olfactory display that presents a scent that can be controlled in time and space, that is, that can present a scent within a limited range of time and space.

  Patent Document 1 discloses an example of a conventional olfactory display. The fragrance generating device of Patent Literature 1 includes a fragrance accommodating portion that accommodates a solid fragrance, and a pump is provided on each of the inlet side and the outlet side of the fragrance accommodating portion. And when generating a fragrance, the inlet side pump is rotated and air is sent to the fragrance accommodating part to push out the air (fragrance) added with the fragrance from the fragrance accommodating part, and at the same time, the outlet side pump is turned on. By rotating, the fragrance is discharged to the outside from the fragrance outlet.

  Another example of a conventional olfactory display is disclosed in Patent Document 2. The gas discharge device of Patent Document 2 is a device that is incorporated in a public information presentation device and provides a scent together with an image, and launches a vortex ring having a scent component by the principle of an air cannon. Specifically, the gas release device of Patent Document 2 includes a plurality of scent discharge tubes whose front ends are inserted between light emitting display elements. A fragrance accumulation mechanism (fragrance source) is provided on the outer peripheral surface of the scent discharge tube via an airflow control plate for opening and closing the scent supply hole. An air layer is provided at the rear end of the scent discharge tube, and a bimorph piezoelectric element is provided in the air layer. When launching the scent, the scent supply hole is opened, and the inner volume of the air layer is instantaneously reduced by curving the bimorph piezoelectric element inward to form a vortex ring from the scent discharge tube. I am trying to fire a lump of fragrance.

  However, in the technique of Patent Document 1, the scent is merely pushed out from the fragrance container by the rotation of the rotor of the pump, that is, the scent is merely diffused into the surrounding space. Is not considered. That is, presentation of a scent to a spatially limited range has not been realized. Further, since the structure is complicated, there is a limit to downsizing.

  Moreover, in the technique of patent document 2, since the lump of scent is fired by the principle of an air cannon, it can only present momentary scent and cannot present continuous scent that is not pulsating. Moreover, since the structure is complicated, such as disposing the scent source outside the main body portion of the gas release device including the scent discharge tube and the air layer, there is a limit to downsizing.

Therefore, the present inventors have proposed an olfactory display in Patent Document 3 that can present a plurality of scents in a space-time-controllable manner while reducing the size of the apparatus. Specifically, the olfactory display of Patent Document 3 includes a housing in which a plurality of aroma chambers partitioned by a partition are formed. Each fragrance chamber is provided with a solid fragrance source and a wind source including a diaphragm with a piezoelectric element attached thereto. In addition, each fragrance chamber is communicated with an injection port via an individual fragrance passage, and each fragrance passage is merged at a position in the vicinity of the injection port to become one shared passage, Is provided with a Venturi tube structure.
JP 2004-121594 A [A61L 9/12] JP 2008-257216 A [G09F 19/00] Japanese Patent Application No. 2012-30611 [A61L 9/12]

  Since there are innumerable scents in the world, ultimately, an olfactory display capable of presenting all the infinite scents is desired. However, in the technique of Patent Document 3, when the number of fragrance chambers is increased in order to present more types of scents (that is, the number of radially formed partition walls is increased), the central connection portion of the partition walls is disconnected accordingly. The area (thickness) is increased, and the aroma chamber is formed at a position away from the injection port in the radial direction. In addition, the space on the jet outlet side of the aroma chamber is also narrowed. For this reason, the fragrance path from the fragrance outlet of the fragrance chamber to the injection outlet must be bent and complicated, which causes a decrease in static pressure (decrease in injection performance). Therefore, in the technique of Patent Document 3, it is difficult to increase the number of fragrance chambers to a certain number or more, and an olfactory display capable of appropriately presenting more types of fragrances is desired.

  Therefore, the main object of the present invention is to provide a novel olfactory display.

  Another object of the present invention is to provide an olfactory display capable of presenting more types of scents in a limited range in terms of time and space, while maintaining miniaturization and simplicity.

  The present invention employs the following configuration in order to solve the above problems.

  In the first invention, the olfactory display (10) includes a first housing (12) having an injection port (16) at the front center and a second housing (14) connected to the rear end. It has a layered structure, and presents a scent in a limited range in terms of time and space in conjunction with an audiovisual display such as a personal computer or a television. Each of the internal spaces of the first housing and the second housing is partitioned by a first partition wall (22) and a second partition wall (26) that are formed in a radial shape. A plurality of aroma chambers (24) arranged in the circumferential direction are formed. In each fragrance chamber, a solid fragrance source (28) is accommodated, and a wind power source (30) for sending air from the air supply port (36) into the fragrance chamber is provided. As the wind power source, a diaphragm (40) to which a piezoelectric element (38) is attached is used, and when a high-frequency alternating voltage is applied to the piezoelectric element, the diaphragm is vibrated to generate an air flow. Each fragrance chamber is formed with an fragrance outlet (62) at the innermost position on the front side thereof. Each of the fragrance delivery ports of the fragrance chamber in the first housing communicates with the injection port substantially linearly through a communication hole (66) formed in the front wall of the first housing. On the other hand, the fragrance delivery port of the fragrance chamber in the second housing is substantially linear with the injection port via the individual fragrance passage (68) passing through the inside of the central connection portion (70) of the first partition wall and the communication hole. Communicated.

  According to the first invention, the casing has a multi-layer structure, and the fragrance passage from each fragrance chamber of the second casing is formed so as to pass through the central coupling portion of the first partition wall. It is possible to increase the number of fragrance chambers while minimizing the bending of the fragrance path from the fragrance outlet to the injection port to suppress the deterioration of the injection performance and to suppress the enlargement of the apparatus. That is, more types of scents can be presented in a limited range in terms of time and space while maintaining miniaturization and simplicity.

  A second invention is dependent on the first invention, and includes a cartridge exchange port formed in the fragrance chamber, and a scent source cartridge that is held in the fragrance chamber from the cartridge exchange port while being held in the scent source. In addition, the scent source cartridge has an outer surface shape that conforms to the inner surface shape of the fragrance chamber, an intake port is formed at a position facing the air supply port, and an fragrance outlet is formed at a position facing the fragrance delivery port. A container body is provided.

  In the second invention, a cartridge exchange port (80) is formed in the aroma chamber (24), and the aroma source cartridge (76) is detachably accommodated in the aroma chamber via the cartridge exchange port. The scent source cartridge includes a container body (84) having an outer surface shape that conforms to the inner surface shape of the fragrance chamber. A solid fragrance source (28) is accommodated in the container body. Further, the container body is formed with an intake port (86) at a position facing the air supply port (36) of the fragrance chamber, and an fragrance outlet (92) at a position facing the fragrance delivery port (62) of the fragrance chamber. It is formed. That is, in the second invention, the solid scent source is not stored directly in the scent chamber, but is stored in the scent chamber through the container body of the scent source cartridge. Thereby, adhesion of the fragrance component to the inner wall surface of the fragrance chamber is prevented.

  According to the second aspect of the present invention, since the cartridge system that detachably accommodates the scent source cartridge in the scent chamber is employed, the corresponding cartridge is used for each scent source, thereby causing confusion of fragrance components. And can provide a variety of fragrances appropriately.

  A third invention is according to the second invention, further comprising a cover provided at the cartridge exchange port for pressing the scent source cartridge in the insertion direction when the scent source cartridge is accommodated in the scent chamber, The inner surface and the outer surface of the container body have inclined surfaces that are inclined with respect to the insertion direction of the scent source cartridge so that the force by which the cover presses the scent source cartridge acts in the direction of pressing the intake port toward the air supply port side. .

  In the third invention, the cartridge exchange port (80) is provided with a cover (82) for pushing the scent source cartridge (76) in the insertion direction. Further, an inclined surface (78) inclined inward with respect to the insertion direction of the scent source cartridge into the scent chamber is formed on the inner side surface of the scent chamber (24), and the container body (84) facing it. An inclined surface (88) is also formed on the outer surface of the cover, so that the force by which the cover pushes the scent source cartridge acts in the direction of pressing the intake port (86) toward the air supply port (36). Thereby, the adhesiveness of the connection part of the air supply port of an aroma chamber and the inlet port of an aroma source cartridge improves.

  According to the third aspect of the present invention, the air supply port and the air intake port can be properly brought into close contact with each other with a simple configuration in which the scent chamber and the scent source cartridge are provided with an inclined structure without providing a complicated mechanism. Therefore, the capacity of the wind source (30) can be utilized to the maximum, and a high static pressure can be generated in the scent source cartridge in a short time.

  According to the fourth aspect of the present invention, the device is difficult to increase in the circumferential direction even if the number of the fragrance chambers (24) in the first housing and the second housing is increased, so that the device can be downsized. Moreover, since the opening for taking in and out the scent source (28) or the cartridge exchange port (80) for attaching and detaching the scent source cartridge (76) can be formed on the side wall of each casing, the scent source or the scent source cartridge can be individually provided. It becomes easy to perform exchange.

  A fifth invention is dependent on any one of the second to fourth inventions, and the incense source cartridge is inserted from the side of the first housing and the second housing.

  In the fifth invention, the cartridge exchange port (80) is formed on the side walls of the first casing (12) and the second casing (14), and the incense cartridge (76) is provided in the first casing and the second casing. Detachable from the side of the body.

  A sixth invention is dependent on the second or third invention, wherein each of the wind power sources is arranged to constitute a part of a side wall of the first housing and the second housing, and the scent source cartridge is It is inserted from above or below the first housing and the second housing.

  In the sixth invention, the wind power source (30) is arranged in the side walls of the first casing (12) and the second casing (14) so as to be aligned in the circumferential direction. In addition, a cartridge exchange port (80) is formed on the front wall or the rear wall of the first casing and the second casing, and the scent source cartridge (76) is viewed from the front or rear of the first casing and the second casing. Detachable.

  According to the sixth invention, since the wind power source is provided in the side wall, the thickness of the partition wall (22, 26) can be reduced, and the cross-sectional area of the central connection portion (70) of the partition wall can be reduced. Thereby, since an aroma exit (92) can be arrange | positioned in the position nearer to an injection port (16), an aroma exit and an injection port can be connected more linearly.

  A seventh invention is according to any one of the first to sixth inventions, and further includes an auxiliary wind source including a diaphragm having a piezoelectric element.

  In 7th invention, the auxiliary | assistant wind source (72) provided independently from each aroma chamber is further provided separately from the wind source (30) provided in each aroma chamber (24). The auxiliary wind source is the same as the wind source, that is, the one having a diaphragm with a piezoelectric element attached thereto, and generating an air flow by vibrating the diaphragm when an alternating voltage is applied to the piezoelectric element. It is done. The auxiliary wind power source is communicated with the auxiliary injection port (94) formed in the vicinity of the injection port (16) or the injection port via the auxiliary passage (74) passing through the inside of the housing (12, 14).

  Referring to FIG. 1 and FIG. 2, an olfactory display 10 according to an embodiment of the present invention adds a scent (olfaction information) to content including video and sound and presents it to the user, thereby realizing the reality of the content. It is used to increase the sense of presence. For example, the olfactory display 10 can be controlled in time and space in conjunction with various audiovisual displays such as a personal computer, a television, a radio, a game machine, a karaoke device, a camera, a DVD player, and a mobile phone, that is, temporally and spatially. Present a fragrance to a limited area.

  FIG. 1 and FIG. 2 show how the olfactory display 10 is used in conjunction with a personal computer as an example. In this case, the olfactory display 10 is installed around the user by being attached to an LCD display, a keyboard, or the like, or attached to a tripod 100 or the like so that the jet 16 for injecting the scent faces the face of the user. Or

  As shown in FIGS. 2 to 4, the olfactory display 10 includes a first housing 12 positioned on the front side (user side) and a second housing 14 integrally provided on the rear side thereof. It has a layer structure. Each of the 1st housing | casing 12 and the 2nd housing | casing 14 is formed in hollow hexagonal column shape with appropriate materials, such as an acrylic resin, a fluororesin, or stainless steel. The first housing 12 and the second housing 14 are connected by being shifted by 30 degrees in the circumferential direction so that each vertex of the first housing 12 is located in the middle of each side of the second housing 14 when viewed from the front. Is done. An injection port 16 is formed at the center of the front wall of the first housing 12. The size of the olfactory display 10 is 65 mm, for example, between the apexes facing each other when viewed from the front, and 100 mm, for example, in the front-rear direction (axial direction). Moreover, the internal diameter of the injection port 16 is 1.0 mm, for example.

  A screw hole 18 for attaching the tripod 100 is formed at an appropriate position of the first housing 12 or the second housing 14. In this embodiment, the screw hole 18 is formed on the rear wall side surface of the second housing 14. The standard of the screw hole 18 is adapted to a camera tripod. Since the standard of the camera tripod screw is standardized by the world standard, if the screw hole 18 is adapted to the standard, the camera tripod around the world can be used as the tripod 100 for the olfactory display 10 as it is. It is convenient because it can.

  Hereinafter, the configuration of the olfactory display 10 will be specifically described. As shown in FIGS. 5 to 9, between the first housing 12 and the second housing 14, a flat partition that becomes the rear wall of the first housing 12 and the front wall of the second housing 14. A wall 20 is provided, and the partition wall 20 partitions the internal space of the first housing 12 and the internal space of the second housing 14 in the front-rear direction. Further, the internal space of the first housing 12 is partitioned by six first partition walls 22 formed radially from the central connecting portion 70 located at the center thereof, and the first housing 12 has a circumferential direction. Six triangular aroma chambers 24 arranged in a row are formed. Similarly, the internal space of the second housing 14 is formed radially so as to connect the opposing vertices, that is, six first sheets formed at positions shifted by 30 degrees in the circumferential direction from the first partition wall 22. The partition wall 26 is partitioned, and in the second housing 14, six triangular columnar aroma chambers 24 arranged in the circumferential direction are formed. That is, the olfactory display 10 has a total of twelve aroma chambers 24 in which six aroma chambers 24 arranged in the circumferential direction are arranged side by side in the front-rear direction. The number of the fragrance chambers 24 formed in each of the first housing 12 and the second housing 14 is not particularly limited. However, considering the downsizing of the apparatus and the fragrance injection performance, the number is changed from four to eight. It is preferable to set.

  In each fragrance chamber 24, a solid fragrance source 28 having a different scent is accommodated. In addition, each of the aroma chambers 24 is provided with a wind power source 30 and an operation sound suppression unit 32 disposed in close contact with the partition walls 22 and 26.

  The solid fragrance source 28 is manufactured, for example, by impregnating (impregnating) a liquid fragrance into a granular porous body and retaining the liquid fragrance on the outer surface and pores of the porous body. As the fragrance, natural fragrances, synthetic fragrances, and blended fragrances thereof can be used as appropriate. As the porous material, a granular material such as calcium silicate, silica gel, rock wool, diatomaceous earth, zeolite, peat, charcoal, vermiculite, bentonite, perlite, carbon nanotube, or activated carbon can be appropriately used. The particle size and shape of the porous body are not particularly limited, but considering the flow path resistance in the fragrance chamber 24 and the like, a spherical body having a particle size of about 1-6 mm is preferable. In this embodiment, each fragrance chamber 24 is filled with 15 fragrance sources 28 in which a liquid fragrance is impregnated with a spherical body of calcium silicate having an average diameter of 4 mm. By using the solid fragrance source 28 in this manner, the fragrance (fragrance component) can be gradually released from the fragrance source 28. That is, since the scent source 28 can continue to release the scent component over a long period of time, the scent is maintained over a long period of time without replenishing the scent source 28 with liquid fragrance or replacing the scent source 28. A display 10 can be used.

  The wind power source 30 is disposed inside the first partition wall 22 and the second partition wall 26 (that is, radially disposed inside the first housing 12 and the second housing 14), and constitutes a part of the partition walls 22 and 26. To do. The nozzle 34 provided at the center of the wind power source 30 communicates with the inside of the aroma chamber 24 and functions as an air supply port 36 through which air flows into the aroma chamber 24. The size of the wind power source 30 is, for example, 20 mm long, 20 mm wide, and 2 mm thick. The diameter of the air supply port 36 (the inner diameter of the nozzle 34) is, for example, 1.0 mm.

  FIG. 10 shows a cross section when the wind power source 30 is cut in a diagonal direction. The wind power source 30 includes a diaphragm 40 to which a piezoelectric element (piezo element) 38 is attached. By applying a high-frequency alternating voltage (sine wave voltage or rectangular wave voltage) to the piezoelectric element 38, the diaphragm 40 is placed on a plate. It is a piezoelectric type that generates a flow of air by bending and vibrating at high speed in the thickness direction.

  Hereinafter, the operation of the wind source 30 will be briefly described. In the wind power source 30, the suction and discharge of air are repeated from the vent hole 44 provided in the center of the pump chamber 42 with the vibration of about 26 kHz of the diaphragm 40 with the disk-shaped piezoelectric element 38 attached. The air taken into the pump chamber 42 from the suction flow path 46 at the time of suction passes through the nozzle 34 on the top plate 48 arranged coaxially with the vent hole 44 at the time of discharge, and expands in the tapered pipe line in the nozzle 34. Discharged. At this time, in the space between the vent hole 44 and the nozzle 34, a negative pressure portion is generated due to the venturi effect, so the air in the suction flow path 46 is continuously sucked. As a result, a continuous pumping operation from the suction channel 46 toward the nozzle 34 is obtained.

  Since the wind power source (piezoelectric wind power source) 30 driven by the piezoelectric element 38 is not a rotating mechanism such as a blower fan or a scroll blower, it can be reduced in size and height, and has low power consumption. . In addition, it has a feature that it can generate a high static pressure in a short time with virtually no vibration. As such a wind power source 30, for example, a micro blower (model number: MZBX001) manufactured by Murata Manufacturing Co., Ltd. can be used.

  Returning to FIG. 5, on the back side of each wind source 30 (upstream side of the air flow path), a plate-like operation for suppressing leakage of the operation sound of the wind source 30 (vibration sound of the diaphragm 40) to the outside. A sound suppression unit 32 is provided. The operation sound suppression unit 32 also constitutes a part of the partition walls 12 and 14. The operation sound suppression unit 32 is formed of an appropriate material such as acrylic resin, fluororesin, or stainless steel, and forms a hollow portion on the back side of the diaphragm 40. The size of the operation sound suppression unit 32 is, for example, 20 mm long, 20 mm wide, and 2 mm thick. As shown in FIGS. 6 and 7, each of the outside air ports 52 (not present in FIGS. 6 and 7) of the operation sound suppression unit 32 is in the outside air intake passage 56 that passes through the partition walls 22 and 26 and the partition wall 20. And is connected to an outside air inlet 58 formed on the rear wall of the second housing 14 and communicates with the outside of the housings 12 and 14.

  FIG. 11 shows a cross section when the operation sound suppression unit 32 is cut in a direction orthogonal to the thickness direction. As shown in FIG. 11, the side wall 50 of the operation sound suppression unit 32 is formed with an outside air port 52 for inhaling outside air when the wind power source 30 is operated, and the inside of the operation sound suppression unit 32 is C-shaped. It is partitioned off by a partition wall 54. As a result, the operating sound of the wind power source 30 reaches the outside air port 52 so as to go around the maze-like air passage, so that leakage of the operating sound from the outside air port 52 (the outside air intake port 58) is suppressed. By providing such an operation sound suppression unit 32, the operation sound can be suppressed and a scent can be presented without causing discomfort to the user. However, the internal structure of the operation sound suppression unit 32 is not limited to the aspect of FIG. For example, a simple cavity without the partition wall 54 may be provided, or a partition wall having another shape may be provided.

  5-9, each fragrance chamber 24 is formed with an opening for inserting the fragrance source 28 into the fragrance chamber 24 (or removing the fragrance source 28 from the fragrance chamber 24). This opening is formed on each side wall of the casings 12 and 14 and is sealed appropriately using a sponge plug 60 made of polyurethane or silicone after the incense source 24 is accommodated.

  Each fragrance chamber 24 is formed with an air supply port 36 and an fragrance delivery outlet 62. As described above, the nozzle 34 of the wind power source 30 functions as the air supply port 36, and each of the air supply ports 36 is formed at the center of the inner side surface of the aroma chamber 24. Each of the fragrance delivery ports 62 is formed at the innermost position on the front side of the fragrance chamber 24.

  A dome-shaped protrusion 64 is provided at the center of the front wall of the first housing 12, and a communication hole 66 extending in the thickness direction of the front wall is formed so as to penetrate the center of the protrusion 64. . The communication hole 66 has a tapered diameter-reducing portion that is reduced in diameter toward the front side, and the front portion is formed in a straight tube shape. The tip opening of the projection 64 functions as the ejection port 16, and the communication hole 66 allows the ejection port 16 to communicate with the fragrance delivery port 62 of each fragrance chamber 24 of the first housing 12. That is, the fragrance delivery port 62 of each fragrance chamber 24 of the first housing 12 is directly connected to the communication hole 66, and the injection port 16 and the fragrance delivery port 62 of each fragrance chamber 24 of the first housing 12 are substantially the same. It communicates in a straight line. On the other hand, the fragrance delivery port 62 of each fragrance chamber 24 of the second housing 14 is connected to the communication hole 66 via an individual fragrance passage 68. Each fragrance passage 68 extends to the communicating hole 66 through the partition wall 20 and the central connecting portion 70 of the first partition wall 22, and the fragrance delivery port 62 of each fragrance chamber 24 of the second housing 14. Are communicated in a substantially straight line. That is, the communication hole 66 is a shared passage for the fragrance discharged from each fragrance chamber 24, and the fragrance from each fragrance chamber 24 is ejected from one injection port 16 through the communication hole 66. The diameter of the injection port 16, the fragrance delivery port 62, and the fragrance passage 68 is, for example, 1.0 mm. Since the diameters of the air supply port 36 and the fragrance outlet 62 are small, fragrance leakage from the fragrance chamber 24 hardly occurs when the wind source 30 is not operated.

  Further, the central connecting portion 70 of each partition wall 22, 26 protrudes from the rear wall of the second housing 14, and its tip end portion extends into the communication hole 66. The distal end portion of the central connecting portion 70 has a tapered shape in which a groove-shaped notch is formed on the outer peripheral surface, and functions as a guide portion that guides the fragrance discharged into the communication hole 66 toward the injection port 16. As a result, the reverse flow of the fragrance and the penetration of the fragrance into the other fragrance chamber 24 are prevented.

  As shown in FIGS. 6 and 7, an auxiliary wind source 72 is provided in the rear wall of the second housing 14. The auxiliary wind source 72 is provided independently of each fragrance chamber 24 and is used for fragrance acceleration, concentration adjustment of fragrance components, deodorization, and the like. The auxiliary wind source 72 includes a diaphragm similar to the wind source 30, that is, a diaphragm with a piezoelectric element attached thereto. When a high frequency alternating voltage is applied to the piezoelectric element, the diaphragm is vibrated at high speed to generate an air flow. It is good to use what is generated. Also on the back side of the auxiliary wind source 72, an operation sound suppression unit 32 is provided as appropriate.

  In addition, an auxiliary passage 74 that is a passage for air (odorless air) discharged from the nozzle of the auxiliary wind power source 72 is formed in the central connecting portion 70. The auxiliary passage 74 is a through hole that linearly communicates the nozzle of the auxiliary wind source 72 and the communication hole 66, and extends linearly to the injection port 16 through the communication hole 66. The diameter of the auxiliary passage 74 is, for example, 1.0 mm. When the auxiliary wind source 72 is activated, odorless air is discharged into the auxiliary passage 74 from the nozzle of the auxiliary wind source 72. Since the odorless air goes straight to the injection port 16 without following a complicated path, the odorless air is injected from the injection port 16 with almost no pressure drop.

  As described above, the olfactory display 10 having such a configuration adds a scent to content including video and sound presented by a personal computer or the like and presents it to the user. For example, according to the change of the scene of the video content, the vanilla scent is emitted in the scene of eating vanilla ice, and the tide is emitted in the seaside scene.

  Specifically, the controller (not shown) of the olfactory display 10 responds to an instruction signal sent from a personal computer or the like, and the piezoelectric of the wind source 30 corresponding to the fragrance chamber 24 containing the target fragrance source 28. An alternating voltage (for example, frequency 26 kHz, 19.5 Vp-p) is applied to the element 38. Then, the diaphragm 40 is flexed and vibrated at a high speed, and outside air is sucked through the outside air suction port 58 and the outside air suction passage 56, and at a high speed from the nozzle 34 (air supply port 36) of the wind power source 30 into the aroma chamber 24. High pressure air is sent. The air in the fragrance chamber 24 contains a gaseous fragrance component volatilized from the fragrance source 28, and the air (fragrance) containing the fragrance component is directly from the fragrance outlet 62 or through the fragrance passage 68. It is discharged into the communication hole 66. In addition, the controller of the olfactory display 10 operates the auxiliary wind source 72 simultaneously with the operation of the wind source 30 corresponding to the fragrance chamber 24 that houses the target fragrance source 28 or by time sharing. The odorless air discharged from the nozzle of the auxiliary wind source 72 passes through the straight auxiliary passage 74 and goes straight to the injection port 16. The fragrance discharged from the fragrance outlet 62 into the communication hole 66 is accelerated by merging with the odorless air discharged from the auxiliary wind source 74 in the communication hole 66, and from the personal computer to the instruction signal almost all the time. The fuel is injected from the injection port 16 with a straight line without any delay. When the application of the alternating voltage to the piezoelectric element 38 is stopped, the fragrance injection from the injection port 16 is also instantaneously stopped.

  At this time, since the piezoelectric wind source 30 is used, the start and stop of the fragrance injection are executed with good responsiveness (that is, accurate time control is possible), and it is not pulsating and constant. It is also possible to present the scent continuously. Further, since the fragrance outlet 62 of each fragrance chamber 24 and the injection port 16 communicate with each other almost linearly, the fragrance discharged from each fragrance outlet 62 goes to the injection port 16 without reducing its momentum. Further, since the communication hole 66 has a reduced diameter portion, the speed of the aroma passing through the communication hole 66 is accelerated by the venturi effect. Therefore, the fragrance is vigorously ejected from the ejection port 16 with directivity, and the scent can be presented in a spatially very limited range (that is, only near the user's face).

  Moreover, since the auxiliary | assistant wind power source 72 is provided, a fragrance can be accelerated and the injection performance of a fragrance improves more. Further, by changing the driving ratio of the wind source 30 and the auxiliary wind source 72 and adjusting the mixing ratio of the fragrance from the fragrance chamber 24 and the odorless air from the auxiliary wind source 72, the concentration control of the scent component is also possible. It becomes possible. Furthermore, after the wind power source 30 is activated and the scent is presented, the auxiliary wind power source 72 is continuously actuated to inject only odorless air, and the presented scent component is volatilized or diluted. Compared with free diffusion, quicker deodorization is possible.

  Furthermore, in this embodiment, twelve aroma chambers 24 are provided, and aroma is injected from one injection port 16 through the communication hole 66. For this reason, not only 12 types of scents can be presented individually, but also the scents can be prepared and presented by operating the wind source 30 of each scent chamber 24 simultaneously or by time sharing. For example, if the scent source 28 accommodated in each scent chamber 24 is A−L, a very large number such as “A + B, A + C,..., K + L, A + B + C,. A variety of scents can be prepared and provided. Moreover, the ratio which mix | blends fragrance can also be changed suitably by adjusting the duty ratio of the input signal of each wind power source 30, etc. FIG.

  According to this embodiment, since the aroma chambers 24 are arranged not only in the circumferential direction but also in the front-rear direction, the aroma is obtained without increasing the cross-sectional area of the central connecting portion 70 of the partition walls 22 and 26. The number of chambers 24 can be increased. In addition, since the fragrance passage 68 from each fragrance chamber 24 of the second housing 14 is formed so as to pass through the central connecting portion of the first partition wall 22, space can be saved and each fragrance chamber 24 of the second housing 14. The fragrance delivery port 62 and the injection port 16 can be connected substantially linearly. That is, the number of the fragrance chambers 24 is suppressed while minimizing the bending of the fragrance path from the fragrance delivery port 62 of each fragrance chamber 24 to the ejection port 16 to suppress the deterioration of the ejection performance and the increase in the size of the apparatus. Can be increased. Therefore, according to this embodiment, it is possible to present more types of scents in a limited range in terms of time and space while maintaining miniaturization and simplicity.

  In this embodiment, since the wind power sources 30 are arranged radially in the casings 12 and 14, even if the number of the fragrance chambers 24 in each of the casings 12 and 14 is increased, the apparatus does not easily increase in the circumferential direction. The device can be miniaturized. Moreover, since the opening for taking in and out the incense source 28 can be formed in the side walls of the casings 12 and 14, the incense source 28 can be easily replaced individually.

  In the above-described embodiment, the auxiliary wind source 72 is provided, but the auxiliary wind source 72 is not necessarily provided. When the auxiliary wind source 72 is not provided, for example, the wind source 30 provided in the fragrance chamber 24 can be caused to function like the auxiliary wind source 72. In this case, at least one of the fragrance chambers 24 is a porous body or non-porous body that does not contain the scent source 28 and is not impregnated with a liquid fragrance, for example, a granular body to which no scent component is added. It is good to store only the granular material such as, or make it a vacant room where nothing can enter. Then, for example, after the scent is presented by operating the wind source 30 of the scent chamber 24 containing the scent source 28, the odorless air is jetted by operating the wind source 30 of the scent chamber 24 that does not store the scent source 28. In this case, quick deodorization is possible. Similarly to the case where the fragrance is adjusted, the wind source 30 of the fragrance chamber 24 containing the fragrance source 28 and the wind source 30 of the fragrance chamber 24 not containing the fragrance source 28 are operated simultaneously or by time sharing. The concentration of the scent component can also be adjusted. Furthermore, if a deodorant is accommodated in at least one of the aroma chambers 24, quicker deodorization after the presentation of the scent becomes possible.

  In addition, when the auxiliary wind source 72 is provided, the discharge performance (static pressure generation capability) of the wind source 30 and the discharge performance of the auxiliary wind source 72 may be set to the same level. The discharge performance of the source 30 can be made higher. Thus, by making the discharge performance of the auxiliary wind power source 72 higher than the discharge performance of the wind power source 30, the flying distance of the scent presentation can be extended, that is, the scent can be carried to a far place. .

  In order to enhance the discharge performance of the auxiliary wind source 72, for example, the auxiliary wind source 72 including a piezoelectric element having a diameter larger than that of the wind source 30 is used, or two or more stages of piezoelectric elements arranged in multiple layers. It is good to use the auxiliary wind source 72 provided with these. Further, for example, when the same wind source 30 and auxiliary wind source 72 are used, the discharge performance of the auxiliary wind source 72 is increased by increasing the alternating voltage applied to the piezoelectric element included in the auxiliary wind source 72. May be. As a specific example, an alternating voltage of 19.5 Vp-p is applied to the piezoelectric element 38 included in the wind power source 30, and an alternating voltage of 30.0 Vp-p is applied to the piezoelectric element included in the auxiliary wind source 72. May be applied. However, if the alternating voltage applied to the piezoelectric element is increased, there may be a problem in the durability of the auxiliary wind source 72. In this case, the auxiliary wind source 72 should not be continuously driven over a long period of time. For example, intermittent driving for about 3 seconds is preferable.

  Moreover, in the above-mentioned Example, although the wind source 30 is arrange | positioned in the partition 22 and 26, it is not limited to this, As shown in FIG. 12, the wind source 30 and the operation sound suppression part 32 are the housing | casing 12. As shown in FIG. , 14 can be arranged side by side in the circumferential direction. In this case, an opening for taking in and out the fragrance source 28 with respect to each fragrance chamber 24 may be formed in the front wall of the first housing 12 and the rear wall of the second housing 14. By providing the wind power source 30 in the side walls of the casings 12 and 14 in this way, the thickness of the partition walls 22 and 26 can be reduced, and the cross-sectional area of the central connection portion 70 that is the central connection portion of the partition walls 22 and 26 is reduced. Can be reduced. As a result, the aroma delivery port 62 can be formed at a position closer to the injection port 16 (auxiliary passage 74 side), and the aroma delivery port 62 and the injection port 16 can be communicated more linearly. become.

  In the above-described embodiment, since the fragrance source 28 is directly enclosed in the fragrance chamber 24, the fragrance component adheres to the inner wall surface of the fragrance chamber 24 after a certain period of time. For this reason, if the scent source 28 in the scent chamber 24 is replaced with the scent source 28 having another type of scent component, the scent component may be confused and the scent may change. Therefore, when replacing the scent source 28 in the scent chamber 24, it is preferable to replace the scent source 28 having the same type of fragrance component.

  Subsequently, an olfactory display 10 which is another embodiment of the present invention will be described with reference to FIGS. In the above-described embodiment, the fragrance source 28 is directly accommodated in the fragrance chamber 24, but in this embodiment, the fragrance source 28 is accommodated in the fragrance chamber 24 via the container body 84 of the fragrance source cartridge 76. Is different. Hereinafter, specific description will be given, but the same reference numerals are given to the same parts as those in the above-described embodiment, and the description will be omitted or simplified.

  As shown in FIGS. 13 to 17, the olfactory display 10 of this embodiment includes a first housing 12 and a second housing 14 that is integrally connected to a rear end portion thereof. Each of the internal spaces of the casings 12 and 14 is partitioned by six partition walls 22 and 26 that are radially formed, and in each of the casings 12 and 14, six triangular column-shaped aroma chambers 24 arranged in the circumferential direction. Is formed. That is, the inner side surface of each fragrance chamber 24 converges toward the center side of the casings 12 and 14 (that is, the two inclined surfaces 78 are inclined inward with respect to the insertion direction of the fragrance source cartridge 76 described later). Have.

  Each of the aroma chambers 24 is provided with a wind power source 30 and an operation sound suppression unit 32. The wind source 30 and the operation sound suppression unit 32 are arranged in close contact with each other inside the partition walls 22 and 26 (that is, arranged radially in the casings 12 and 14), and the nozzle 34 of the wind source 30 is placed in the aroma chamber 24. It functions as an air supply port 36 through which air flows. In addition, an aroma delivery port 62 is formed at the innermost position on the front side of each aroma chamber 24. The fragrance outlet 62 of this embodiment is formed slightly larger than the fragrance outlet 92 of the fragrance source cartridge 76 described later, so that the fragrance discharged from the fragrance outlet 92 is smoothly guided to the communication hole 66 or the fragrance passage 68. To be.

  In addition, on the side walls of the casings 12 and 14, a cartridge exchange port 80 for attaching and detaching the scent source cartridge 76 to and from each scent chamber 24 is formed. Each of the cartridge exchange ports 80 is provided with a cover 82 that can be opened and closed by a hinge or the like. The cover 82 abuts against the rear end of the scent source cartridge 76 in the insertion direction when the scent source cartridge 76 is accommodated in the scent chamber 24, and exerts an action of pushing the scent source cartridge 76 in the insertion direction.

  In the fragrance chamber 24, the scent source cartridge 76 is detachably accommodated. The scent source cartridge 76 includes a container main body 84 and a solid scent source 28 accommodated therein. That is, the scent source 28 is accommodated in the scent chamber 24 via the container body 84 of the scent source cartridge 76.

  As shown in FIGS. 18 and 19, the container body 84 of the scent source cartridge 76 is formed of a synthetic resin such as polyethylene or polypropylene, and is hollow so as to have an outer surface shape that conforms to the inner surface shape of the fragrance chamber 24 without a gap. It is formed in a regular triangular prism shape. In the container main body 84, when the scent source cartridge 76 is accommodated in the scent chamber 24, an intake port 86 is formed at a position facing the air supply port 36 of the scent chamber 24 (see FIG. 16). That is, the outer surface of the container body 84 has two inclined surfaces 88 that converge with respect to the insertion direction of the scent source cartridge 76, and an intake port 86 is formed on one of the inclined surfaces 88. The diameter of the intake port 86 is, for example, 1.0 mm.

  In the container main body 84, an aroma outlet 92 is formed at a position facing the aroma outlet 62 of the aroma chamber 24 (see FIGS. 14 and 15). The diameter of the fragrance outlet 92 is, for example, 1.0 mm. Each of the fragrance outlets 92 communicates with the injection port 16 almost linearly through each of the fragrance passages 68 and the communication holes 66. Therefore, the fragrance delivered from each of the fragrance outlets 92 has no injection force, and the injection port is reduced. 16 is injected. Further, since the internal paths of the casings 12 and 14 with which the fragrance delivered from the fragrance source cartridge 76 comes into contact are only the communication holes 66 and the fragrance passages 68, almost no fragrance component adheres to the casings 12 and 14. Absent. Since the diameters of the air inlet 86 and the fragrance outlet 92 are small, fragrance leakage from the fragrance cartridge 76 (fragrance chamber 24) hardly occurs when the wind power source 30 is not operated.

  When the scent source cartridge 76 is housed in the scent chamber 24, the cover 82 is opened and the scent source cartridge 76 is housed in the scent chamber 24 so as to push the scent source cartridge 76 from the cartridge exchange port 80 toward the central connecting portion 70. . Thereafter, by closing the cover 82, the rear end side in the insertion direction of the scent source cartridge 76 (container body 84) is suppressed by the cover 82. At this time, as shown in FIG. 20, since the fragrance chamber 24 has an inclined surface 78 inclined inward with respect to the insertion direction, the force F that the cover 82 pushes the fragrance source cartridge 76 in the insertion direction is the fragrance chamber. 24 inclined surfaces 78 are received. The force F <b> 1 acting on the inclined surface 78 of the fragrance chamber 24 has a vector component F <b> 1 a perpendicular to the inclined surface 78. That is, since the force F1a that presses the inclined surface 88 of the scent source cartridge 76 against the inclined surface 78 of the scent chamber 24 acts, the connection portion between the air supply port 36 of the scent chamber 24 and the intake port 86 of the scent source cartridge 76 is in close contact. Increases the ability to adhere properly. Therefore, almost no air leakage occurs at this connecting portion, and a high static pressure can be generated in the scent source cartridge 76 in a short time by making the best use of the capability of the wind source 30.

  Further, since the fragrance chamber 24 and the fragrance source cartridge 76 have inclined surfaces 78 and 88 that are inclined inward with respect to the insertion direction, the inlet portion of the fragrance chamber 24 (that is, the cartridge exchange port 80) It becomes larger than the portion on the front side in the insertion direction. For this reason, it is easy to insert the scent source cartridge 76 into the scent chamber 24.

  Further, since the scent source 28 is housed in the scent source cartridge 76 (container body 84), and this scent source cartridge 76 is detachably housed in the scent chamber 24, the scent component is contained on the inner wall surface of the scent chamber 24. It will not adhere. Therefore, even if the scent source cartridge 76 is replaced, the fragrance components are not confused, and by replacing the scent source cartridge 76, a myriad of scents can be appropriately provided. Further, since the wind power sources 30 are arranged radially, the cartridge exchange port 80 can be formed on the side walls of the casings 12 and 14. For this reason, compared with the case where the cartridge exchange port 80 is formed on the front wall or the rear wall of the casings 12 and 14, it becomes easier to provide the cover 82 for each cartridge exchange port 80 individually, and the individual replacement of the incense cartridge 76 is performed. Becomes simple.

  According to the embodiment shown in FIGS. 13-17, since the cartridge system in which the scent source cartridge 76 is detachably accommodated in the scent chamber 24 is adopted, various kinds of scents can be produced without causing confusion of scent components. Can be provided appropriately. Further, when the cartridge system is adopted, inclined surfaces 78 and 88 that are inclined with respect to the insertion direction of the scent source cartridge 76 are formed on the inner side surface of the scent chamber 24 and the outer side surface of the scent source cartridge 76 (container body 84). Thus, the connection portion between the air supply port 36 of the fragrance chamber 24 and the intake port 86 of the scent source cartridge 76 is appropriately brought into close contact. That is, the air supply port 36 and the intake port 86 are in close contact with each other with a simple structure in which the aroma chamber 24 and the aroma source cartridge 76 are provided with an inclined structure without using a complicated mechanism (biasing means such as a leaf spring). Thus, it is possible to generate a high static pressure in the scent source cartridge 76 in a short time by making the best use of the capability of the wind source 30. Therefore, according to this embodiment, innumerable scents can be presented in a limited range in terms of time and space while maintaining miniaturization and simplicity.

  13-17, when the scent source cartridge 76 is accommodated in the scent chamber 24, the cover 82 pushes the rear end of the scent source cartridge 76 in the insertion direction, so that the air supply port 36 and The connection portion with the intake port 86 is more closely attached. However, it is not always necessary to push the scent source cartridge 76 by the cover 82. The scent source cartridge 76 is formed of a relatively soft material such as polyethylene. For this reason, when the fragrance source cartridge 76 is pushed into the fragrance chamber 24, the fragrance chamber 24 and the fragrance source cartridge 76 have the inclined surfaces 78 and 88 inclined inward with respect to the insertion direction, so The cartridge 76 is fitted. As a result, the force (the force in the insertion direction) when pushing the scent source cartridge 76 into the scent chamber 24 is maintained, and the force for pressing the inclined surface 88 of the scent source cartridge 76 against the inclined surface 78 of the scent chamber 24 acts. Therefore, the connection portion between the air supply port 36 and the air intake port 86 is properly adhered.

  Further, in order to further improve the adhesion of the connection portion between the air supply port 36 of the fragrance chamber 24 and the intake port 86 of the fragrance source cartridge 76, the outer surface of the container body 84 of the fragrance source cartridge 76 or the inner surface of the fragrance chamber 24. On the other hand, an elastic material layer (not shown) formed of a highly flexible elastic material such as silicone rubber can be laminated. For example, an elastic material layer may be formed on each of the two inclined surfaces 88 of the container main body 84, or an elastic material layer may be formed on the outer surface of the container main body 84 on which the intake port 86 is formed. Also good.

  Furthermore, as shown in FIG. 21, a protruding portion 90 may be formed with respect to the container body 84 of the scent source cartridge 76. Specifically, the protruding portion 90 is formed in a beak shape (triangular pyramid shape), and protrudes from the front end portion of the container body 84 toward the central connecting portion 70 side. An aroma outlet 92 is formed with respect to the protruding portion 90. In this manner, by forming the beak-shaped protrusion 90 on the container body 84, the fragrance outlet 92 (and the fragrance outlet 62 of the fragrance chamber 24) is formed at a position closer to the injection port 16 (auxiliary passage 74 side). Thus, the fragrance outlet 92 and the injection port 16 can be communicated more linearly.

  Furthermore, in the embodiment shown in FIGS. 13-17, a laterally open type cover using a hinge is adopted as the cover 82 provided at the cartridge exchange port 80 and pushing the scent source cartridge 76 in the insertion direction. The specific embodiment is not particularly limited. For example, a slide-type cover may be employed, or a completely removable cover may be employed.

  13 to 17, the cartridge exchange port 80 is formed on the side walls of the casings 12 and 14, and the scent source cartridge 76 is directed from the side of the casings 12 and 14 toward the central connecting portion 70. However, the present invention is not limited to this. For example, the cartridge exchange port 80 is formed on the front wall of the first housing 12 and the rear wall of the second housing 14, and the first housing 12 is scented from the front side, and the second housing 14 is scented from the rear side. The source cartridge 76 can also be attached and detached. In this case, as shown in FIG. 22, the wind power source 30 and the operation sound suppression unit 32 may be disposed in the side walls of the casings 12 and 14. However, the inner surface of the fragrance chamber 24 and the fragrance cartridge 76 (container body 84) of the fragrance chamber 24 are arranged so that the force for pushing the fragrance source cartridge 76 into the fragrance chamber 24 acts in the direction of pressing the intake port 86 toward the air supply port 36. It is preferable to form an inclined surface that is inclined with respect to the insertion direction of the scent source cartridge 76 on the outer surface.

  Further, in the embodiment shown in FIGS. 13 to 17, the cartridge system is adopted for all the fragrance chambers 24, but the cartridge system may be adopted for some of the fragrance chambers 24. For example, a cartridge system may be adopted for the aroma chamber 24 of the first housing 12 and the aroma source 28 may be directly accommodated in the aroma chamber 24 of the second housing 14. Furthermore, the arrangement | positioning position of the wind power source 30 can be changed with the 1st housing | casing 12 and the 2nd aroma chamber 14, and the insertion direction of the aroma source cartridge 76 can also be varied. That is, the scent source cartridge 76 is inserted into the scent chamber 24 of the first housing 12 from the front, and the scent source cartridge 76 is inserted into the scent chamber 24 of the second housing 14 from the side, or the first The scent source cartridge 76 may be inserted into the scent chamber 24 of the housing 12 from the side, and the scent source cartridge 76 may be inserted into the scent chamber 24 of the second housing 14 from the rear.

  In each of the above-described embodiments, there is one injection port 16 formed in the first housing 12, and the fragrances from the fragrance chambers 24 or the fragrance source cartridges 76 are merged through the communication holes 66 to be 1 Although it injected from the one injection port 16, it is not limited to this. For example, as shown in FIGS. 23 to 25, the olfactory display 10 can also have a plurality of injection ports 16. 23 to 25 show the cartridge-type olfactory display 10, a plurality of injection ports 16 may be formed in the olfactory display 10 of the type that directly accommodates the scent source 28.

  23 to 25, in the olfactory display 10 of this embodiment, twelve injection ports 16 arranged in a circular shape are formed with respect to the central portion of the front wall of the first housing 12. The distance between the adjacent injection ports 16 is, for example, 1 mm.

  Each scent outlet / outlet 60 of the scent chamber 24 of the first housing 12 communicates with each of the corresponding ejection ports 16 via a communication hole 66 that penetrates the front wall of the first housing 12. That is, the fragrance discharged from the fragrance outlet 92 of the fragrance source cartridge 76 attached to the first housing 12 is ejected from the individual ejection ports 16 through the individual communication holes 66. On the other hand, each fragrance delivery port 60 of the fragrance chamber 24 of the second housing 14 corresponds to the interior of the central coupling portion 70 of the first partition wall 22 and the fragrance passage 68 penetrating the front wall of the first housing 12. Communicating with each of the injection ports 16. That is, the fragrance discharged from the fragrance outlet 92 of the fragrance source cartridge 76 attached to the second housing 14 is ejected from the individual ejection ports 16 through the individual fragrance passages 68.

  The fragrance inlet portion (fragrance outlet 60) of each communication hole 66 and each fragrance passage 68 is formed to be slightly larger than the fragrance outlet 92 of the fragrance source cartridge 76. Each communication hole 66 and each fragrance passage 68 are reduced in diameter from the fragrance outlet 60 into a taper shape and extend straight forward toward the front. Thereby, the fragrance discharged from the fragrance outlet 92 of the fragrance source cartridge 76 is smoothly guided to the corresponding ejection port 16 via the communication hole 66 or the fragrance passage 68.

Further, the angle at which the first partition wall 22 of the first housing 12 and the second partition wall 26 of the second housing 14 are shifted in the circumferential direction may not be 30 degrees, and the aroma delivery port 62 of the first housing 12 is not necessary. And the scent delivery port 62 of the second housing 14 only need to be covered in the front-rear direction.

  Further, in each of the above-described embodiments, the first housing 12 and the second housing 14 are integrally formed, but the first housing 12 and the second housing 14 are formed so as to be separable. You can also. In this case, when the cartridge system is adopted, the scent source cartridge 76 can be inserted from both the first case 12 and the second case 14 from the front side, or the scent source cartridge 76 from the rear side. Can also be inserted.

  In each of the above-described embodiments, the two-layer structure having the first housing 12 and the second housing 14 is used. However, a three-layer structure may be used. That is, a third housing (not shown) can be connected to the rear end portion of the second housing 14 in an integrated or separable manner. In this case, each of the first housing 12, the second housing 14, and the partition walls provided in the third housing is arranged so as to be shifted in the circumferential direction, and the aroma from the aroma delivery port of the aroma chamber of the third housing. The passage may be formed so as to extend to the communication hole 66 through the partition walls 22 and 26 of the second housing 14 and the first housing 12. The auxiliary wind source 72 may be provided on the rear wall of the third housing.

  Further, in each of the above-described embodiments, the solid fragrance source 28 used is a granular porous body infiltrated with a liquid fragrance, but is not limited thereto. For example, after a liquid fragrance is dissolved in a solid or gel-like substrate liquefied by heating at room temperature, the solid fragrance that is solidified or gelled by cooling to room temperature is used as the solid fragrance source 28. You can also. However, from the viewpoint that it can be easily and inexpensively manufactured and the liquid fragrance can be replenished, it is preferable to use a solid fragrance source 28 in which a porous material is impregnated with a liquid fragrance.

  Furthermore, in each of the above-described embodiments, the olfactory display 10 is fixedly installed and the scent is ejected only in one direction. However, the present invention is not limited to this, and the olfactory display is configured so that the ejection direction can be displaced. 10 can also be installed. For example, the olfactory display 10 can be installed on a pedestal that supports the olfactory display 10 so as to be rotatable in the horizontal direction and the vertical direction. In this case, in combination with a device for detecting the position of the user's nose, the user's nose may be automatically tracked to present the scent.

  In each of the above-described embodiments, the scent is presented in conjunction with the audiovisual information. However, the scent can be presented alone. For example, in vehicles such as automobiles, the sense of snoozing of the driver is detected based on facial images, etc., and in response to the detection, the scent (irritating odor) is released toward the driver's nose as an olfaction device. A display 10 can also be used. The olfactory display 10 can present a scent to a spatially limited range (that is, has directivity), so that it can present a stimulating odor only to the driver without affecting other passengers. . Further, for example, different scents may be presented according to the temperature, humidity and weather of the day.
