[0011] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In all the drawings, the same components are given the same reference numerals and the description will be omitted as appropriate.

[0012] (First embodiment) FIG. 1 is a diagram illustrating the configuration of an odor component set 300 according to the first embodiment. The odor component set 300 according to this embodiment includes a plurality of storage sections 30. Each of the plurality of storage sections 30 stores an odor component. The plurality of storage sections 30 includes a first storage section 30a that stores a first odor component (e.g., an odor component of A) and a second storage section 30b that stores the first odor component. The amount of the first odor component stored in the first storage section 30a (component amount V1a) is different from the amount of the first odor component stored in the second storage section 30b (component amount V2a). This will be explained in detail below.

[0013] As described above, the odor component set 300 according to this embodiment includes multiple storage units 30 with different amounts of the same odor component. The amount of the odor component stored in the storage unit 30 corresponds to the concentration of the odor component output from the storage unit 30, i.e., the odor intensity. More specifically, the greater the amount of the odor component stored in the storage unit 30, the higher the concentration of the odor component output from the storage unit 30, i.e., the stronger the odor intensity.

[0014] As will be described in detail below, the concentration of the first odor component contained in the first storage portion 30a may be different from the concentration of the first odor component contained in the second storage portion 30b.

[0015] A user of the odor component set 300 sequentially smells the odors output from the multiple storage units 30 of the same odor component. The user can recognize their own olfactory level according to which storage unit 30 the user has smelled from among the multiple storage units 30. For example, in the following cases 1 to 3, case 1 corresponds to the case where the user's olfactory function is the lowest, and case 3 corresponds to the case where the user's olfactory function is the highest. Case 1: The user could not detect any odor from any of the storage units 30. Case 2: A case in which the user could only detect an odor from the storage section 30 containing a large amount of odor components Case 3: The user sensed odors from all of the storage compartments 30

[0016] For example, if the user's olfactory function is improved by olfactory training, the user will be able to sense odors from the storage section 30 with a smaller amount of components. This allows the user to subjectively recognize that his or her olfactory function has improved. In other words, the user can feel the effects of olfactory training. This in turn increases the user's motivation for olfactory training, and improves the continuity of olfactory training.

[0017] The use of the odor component set 300 is not limited to olfactory training. The odor component set 300 may be used, for example, for olfactory measurement. The more a user can detect the odor of the same odor component from the storage unit 30 containing a smaller amount of the odor component, the higher the olfactory function of the user can be determined. In addition, the user himself / herself can subjectively recognize his / her own olfactory level through olfactory measurement using the odor component set 300.

[0018] FIG. 2 is a diagram illustrating another configuration of the odor component set 300 according to this embodiment. The storage section 30 may include three or more storage sections 30 that store the first odor component. However, the amount of the first odor component stored in these storage sections 30 is different from each other. In the example shown in FIG. 2, the odor component set 300 further includes a storage section 30 that stores an amount of the first odor component different from the first storage section 30a and the second storage section 30b. That is, the odor component set 300 includes a storage section 30 that contains the odor of A in a component amount V1a, a storage section 30 that contains the odor of A in a component amount V2a, and a storage section 30 that contains the odor of A in a component amount V3a. The component amount V1a, the component amount V2a, and the component amount V3a are different from each other.

[0019] In addition, the multiple storage units 30 may further include a third storage unit 30c that stores a second odor component different from the first odor component. By including the multiple storage units 30 in the third storage unit 30c that stores the second odor component, for example, olfactory training can be continued without getting bored. In the example of FIG. 2, the third storage unit 30c stores an odor component B that is different from the odor A. Furthermore, the odor component set 300 may include multiple storage units 30 that store different amounts of the second odor component. In the example shown in FIG. 2, the odor component set 300 includes a storage unit 30 that contains the odor of B in a component amount V1b, a storage unit 30 that contains the odor of B in a component amount V2b, and a storage unit 30 that contains the odor of B in a component amount V3b. The component amount V1b, the component amount V2b, and the component amount V3b are different from each other. The component amounts V1a and V1b do not have to be the same. The same applies to the relationship between the component amounts V2a and V2b, and the relationship between the component amounts V3a and V3b. The concentrations of the odor components in the storage section 30 containing the odor of A in the component amount V1a, the storage section 30 containing the odor of A in the component amount V2a, and the storage section 30 containing the odor of A in the component amount V3a may be different from each other.

[0020] Examples of odor components include floral odor components, citrus odor components, herbal odor components, woody odor components, spice odor components, exotic odor components, etc. Examples of floral odor components include rose odor components and lavender odor components. Examples of citrus odor components include orange odor components, grapefruit odor components, lemon odor components, etc. Examples of herbal odor components include peppermint odor components and rosemary odor components. Examples of woody odor components include eucalyptus odor components and cypress odor components, etc. Examples of spice odor components include ginger odor components and cinnamon odor components, etc. Examples of exotic odor components include ylang-ylang odor components and sandalwood odor components, etc. Each odor component is an aromatic compound or a mixture of multiple aromatic compounds.

[0021] The storage section 30 stores an odor composition containing odor components. The odor composition is obtained, for example, by mixing an essential oil with a solvent. The essential oil contains odor components. An example of the solvent is alcohol such as ethanol. The odor composition may further contain a deterioration inhibitor.

[0022] The storage section 30 may store the scent composition in liquid form alone. The storage section 30 may also store the scent composition in a state where the scent composition is soaked into a substrate. Examples of substrates include paper, fibers such as cotton, wood, porous materials, and the like.

[0023] The method of adjusting the amount of odor components stored in the storage section 30 is not particularly limited. For example, for the same odor component, the concentration of the odor component in the odor composition stored in the storage section 30 may be different from each other in the multiple storage sections 30. In this case, the amount of the odor composition stored in the storage section 30 may be the same in the multiple storage sections 30. As another example, for the same odor component, the amount of the odor composition stored in the storage section 30 may be different from each other in the multiple storage sections 30. In this case, the concentration of the odor component in the odor composition stored in the storage section 30 may be the same in the multiple storage sections 30. That is, the first storage section 30a and the second storage section 30b may differ in at least one of the amount of the odor composition stored and the concentration of the odor component in the odor composition stored.

[0024] When the first storage section 30a contains an odor composition containing a first odor component at a volume concentration C1, and the second storage section 30b contains an odor composition containing a first odor component at a volume concentration C2, the volume concentration C1 is preferably 1 or more times the volume concentration C2, preferably 1.2 or more times, and more preferably 1.5 or more times. Moreover, the volume concentration C1 is preferably 100 or less times the volume concentration C2, and more preferably 10 or less times. By making the volume concentration C1 and the volume concentration C2 different, the amount of the components contained in the first storage section 30a and the second storage section 30b can be easily made different.

[0025] The storage section 30 is made of, for example, one or more of resin, glass, and metal. The shape of the storage section 30 is not particularly limited, and may be, for example, box-shaped, bottle-shaped, or bag-shaped. At least at the time of shipping the scent component set 300, the storage section 30 is sealed. The multiple storage sections 30 may or may not be connected to each other. The storage spaces of the multiple storage sections 30 that store the scent components are independent of each other.

[0026] The method of using the odor component set 300 will be described below.

[0027] A user of the odor component set 300 smells the odor released from the storage unit 30. The method of releasing the odor from the storage unit 30 is not particularly limited. The user may release the odor by opening the storage unit 30. Alternatively, the user may release the odor using an odor output device.

[0028] When using an odor output device to release an odor, for example, a user removes the contents in the storage section, i.e., the odor composition or a substrate impregnated with the odor composition, from the storage section 30 and transfers it to the holding section of the odor output device. The user then operates the odor output device to release the odor from the storage section 30. The holding section of the odor output device may be capable of simultaneously holding the odor compositions or substrates from multiple storage sections 30, or may be capable of holding only one of them at a time.

[0029] The method by which the odor output device emits an odor is not particularly limited. Examples of the method by which the odor output device emits an odor include vaporization and spraying. For example, the odor output device may include one or more of a heater, a fan, an ultrasonic vibrator, and a pump.

[0030] As another example, the odor output device may have a holding part that holds the storage part 30. In that case, the user does not need to remove the odor composition or the substrate impregnated with the odor composition from the storage part 30. The user holds the storage part 30 in the holding part of the odor output device. The user also unseals the storage part 30 before releasing the odor. The user then operates the odor output device to release the odor from the storage part 30. The holding part of the odor output device may be capable of holding multiple storage parts 30 at the same time, or may be capable of holding only one at the same time. An example in which the odor output device has a holding part that holds multiple storage parts 30 will be described in detail in the second embodiment.

[0031] The following describes an olfactory training method that includes a user smelling an odor output using the odor component set 300. This olfactory training method can be used for at least one of preventing and improving cognitive dysfunction, for example. This olfactory training method may also be used for improving insomnia or depression.

[0032] The user releases odors one by one from the multiple storage units 30 that store the same odor component. In this way, the user smells the odors from the multiple storage units 30 in order. It is preferable for the user to smell the odors output from the multiple storage units 30 that store the same odor component in order from the storage unit 30 with the least amount of component, that is, in order of weakest odor. The user then understands the strength of the odor that he or she was able to sense. By continuing this type of training every day, the user can improve their olfactory function while recognizing the effects of the training.

[0033] According to this embodiment, the amount of the first odor component contained in the first storage unit 30a is different from the amount of the first odor component contained in the second storage unit 30b. Therefore, a user who smells the odors released from the first storage unit 30a and the second storage unit 30b can easily realize his or her own olfactory level.

[0034] Second embodiment FIG. 3 is a perspective view illustrating an odor output device 10 according to a second embodiment. FIG. 4 is a top view illustrating an odor output device 10 according to this embodiment. In FIG. 4, the storage space 310 of the storage section 30 is indicated by a dashed line. FIG. 5 is a cross-sectional view illustrating an odor output device 10 according to this embodiment. FIG. 5 corresponds to the AA cross section of FIG. 4. The X-axis, Y-axis, and Z-axis shown in each figure are three axes that are perpendicular to each other. Note that the structure of the odor output device 10 is not limited to the examples shown in these figures.

[0035] The odor output device 10 according to this embodiment includes a holding section that holds a plurality of storage sections 30 according to this embodiment. The plurality of storage sections 30 according to this embodiment are included in an odor component set 300 according to this embodiment. The storage section 30 and the odor component set 300 according to this embodiment are the same as the storage section 30 and the odor component set 300 according to the first embodiment, respectively, except for the points described below.

[0036] The odor output device 10 according to this embodiment includes a holding section 50 and an output section 52. The holding section 50 holds a plurality of storage sections 30 that store odor components. The output section 52 outputs odors from the plurality of storage sections 30 independently of each other. The plurality of storage sections 30 include a first storage section 30 that contains a first odor component and a second storage section 30 that contains the first odor component. The amount of the first odor component contained in the first storage section 30 is different from the amount of the first odor component contained in the second storage section 30.

[0037] In the example of FIG. 5, the multiple storage sections 30 included in the odor component set 300 are integrated. By integrating the multiple storage sections 30, the multiple storage sections 30 can be easily handled together. The multiple storage sections 30 included in the odor component set 300 are at least a part of a cartridge 60 that can be used in the odor output device 10. That is, the odor component set 300 can include one or more cartridges 60. All of the storage sections 30 included in the odor component set 300 may be included in one cartridge 60, or the multiple storage sections 30 included in the odor component set 300 may be divided and included in two or more cartridges 60. The holding section 50 may be configured to hold multiple cartridges 60 at the same time. By having the multiple storage sections 30 be at least a part of the cartridge 60, the odor component set 300 can be easily used by the odor output device 10.

[0038] The holding part 50 and the cartridge 60 are combined to function as the odor output device 10. In the example of Fig. 5, the odor output device 10 is used with at least a part of the cartridge 60 exposed.

[0039] A storage space 310 is provided inside the storage unit 30, and an odor composition 320 containing an odor component is stored in the storage space 310. The odor composition may be stored in the form of a liquid alone in the storage space 310, or a substrate impregnated with the odor composition may be stored. In the example of FIG. 4, when the Z-axis direction is viewed as the line of sight, the multiple storage spaces 310 are arranged along the circumferential direction of the odor output device 10.

[0040] The cartridge 60 has a plurality of storage sections 30 and a connection section 620. The connection section 620 connects the plurality of storage sections 30 to each other. Note that the cartridge 60 may not have the connection section 620, and the storage sections 30 may be directly coupled to each other to form the cartridge 60.

[0041] 5, the connection part 620 and the multiple storage parts 30 are integral and cannot be detached from one another. However, the multiple storage parts 30 may be detachable from the connection part 620, or the multiple storage parts 30 may be separable from one another. The cartridge 60 is made of, for example, resin.

[0042] The cartridge 60 is provided with a hole 610 for each storage section 30. The hole 610 connects the storage space 310 to the outside. The odor from the odor composition 320 is released to the outside through the hole 610. When the odor component set 300 is shipped, the hole 610 is sealed with, for example, a seal, to seal the storage section 30. Before releasing the odor from the storage section 30, the seal is removed and the storage section 30 is unsealed.

[0043] FIG. 6 is an exploded perspective view illustrating the structure of the holding unit 50 and the cartridge 60. In FIG. 6, the internal components of the holding unit 50 are not shown. In the example of FIG. 6, the holding unit 50 is at least partially cylindrical. The holding unit 50 has an opening 500. A part of the cartridge 60 is inserted into the opening 500 in the holding unit 50. When the holding unit 50 holds the cartridge 60, at least a part of the inner surface of the opening 500 in the holding unit 50 and at least a part of the outer surface of the cartridge 60 face each other. In the example of FIG. 6, the cartridge 60 has a guide portion 601 that can function as a guide when attaching the cartridge 60 to the holding unit 50 of the odor output device 10.

[0044] On the other hand, the holding part 50 is provided with a guide part 501. In the example of FIG. 6, the guide part 601 of the cartridge 60 is a convex part provided on a surface facing the holding part 50, and the guide part 501 of the holding part 50 is a concave part provided on a surface facing the cartridge 60. Only when the positions of the guide part 601 of the cartridge 60 and the guide part 501 of the holding part 50 are aligned, the guide part 601 of the cartridge 60 is inserted into the guide part 501 of the holding part 50, and the cartridge 60 can be attached to the holding part 50. In this way, the cartridge 60 can be easily attached to the holding part 50 in the correct orientation. When a user is undergoing olfactory training for the purpose of preventing dementia, etc., it is assumed that the user is an elderly person. Therefore, it is very important that the odor output device 10 is easy to use.

[0045] The structures of the holding part 50 and the cartridge 60 are not limited to the example shown in the figure. For example, the guide part 601 of the cartridge 60 may be a recess and the guide part 501 of the holding part 50 may be a protrusion. The cartridge 60 may have guide parts 601 in two or more places. In this case, it is preferable that the number of guide parts 601 of the cartridge 60 is the same as the number of guide parts 501 of the holding part 50. It is also preferable that the widths of the guide parts 601 are different from each other, so that the state when the cartridge 60 is attached to the holding part 50 is uniquely determined.

[0046] The holding unit 50 is provided with an output unit 52 for emitting an odor from the storage unit 30. The output unit 52 is, for example, a heater or an ultrasonic vibrator. When the output unit 52 is a heater or an ultrasonic vibrator, as shown in FIG. 5, the output unit 52 is abutted against the storage unit 30 while the holding unit 50 holds the cartridge 60. The output unit 52 may further include a fan. However, the output unit 52 is not limited to these examples. Examples of the method by which the odor output device 10 emits an odor include evaporation and spraying. However, it is preferable that the emission of the odor from the storage unit 30 can be quickly switched, and it is preferable that the output unit 52 is, for example, an ultrasonic vibrator.

[0047] In the example of Fig. 5, multiple output units 52 are provided inside the holding unit 50. That is, the odor output device 10 has an output unit 52 for each storage unit 30. The odor output device 10 also has an operation unit 51 for each of the multiple storage units 30 for outputting an odor from that storage unit 30. The operation unit 51 is, for example, a switch. In the examples of Figs. 3 and 5, the operation unit 51 is provided on the outer surface of the odor output device 10. By providing an operation unit 51 for each of the multiple storage units 30, it is possible to easily generate an odor from each storage unit 30.

[0048] The odor output device 10 further includes a drive circuit 56. The drive circuit 56 activates and stops the output unit 52 depending on whether the operation unit 51 is ON or OFF. In the example of Fig. 5, the odor output device 10 includes only one drive circuit 56, which is connected to multiple operation units 51 and multiple output units 52. However, the odor output device 10 may include a drive circuit 56 for each pair of an operation unit 51 and an output unit 52.

[0049] When any of the operation units 51 is operated (for example, when a switch is pressed), the output unit 52 corresponding to that operation unit 51 is turned on for a predetermined period of time. Then, an odor is released from the storage unit 30 corresponding to the output unit 52 in the ON state.

[0050] The odor output device 10 may include only one output unit 52. In this case, the odor output device 10 is configured so that the operation unit 51 can switch which of the multiple storage units 30 the output unit 52 acts on. For example, when any operation unit 51 is operated, the output unit 52 acts only on the storage unit 30 corresponding to that operation unit 51, and the odor is released from the storage unit 30 that the output unit 52 acts on.

[0051] The method of using the odor component set 300 and the odor output device 10 according to this embodiment will be described below. The odor component set 300 and the odor output device 10 can each be used for, for example, preventing and / or improving cognitive dysfunction. The odor component set 300 and the odor output device 10 can also be used for improving insomnia or depression.

[0052] A user of the odor component set 300 holds the cartridge 60, which has unsealed each storage section 30, in the storage section 50 of the odor output device 10. The user then operates the multiple operating sections 51 of the odor output device 10 in sequence to release the odor from the storage section 30.

[0053] The following describes an olfactory training method that includes a user smelling an odor output using the odor component set 300. This olfactory training method can be used for at least one of preventing and improving cognitive dysfunction, for example. This olfactory training method may also be used for improving insomnia or depression.

[0054] The user sequentially releases odors from multiple storage units 30 that store the same odor component. In this way, the user sequentially smells the odors from the multiple storage units 30. It is preferable for the user to smell the odors output from the multiple storage units 30 that store the same odor component in order from the storage unit 30 with the least amount of component, that is, in order of weakest odor. The user then understands the strength of the odor that he or she was able to sense. By continuing this type of training every day, the user can improve their olfactory function while recognizing the effects of the training.

[0055] A preferred olfactory training will be described in more detail below. In the example of Fig. 3 and Fig. 4, the cartridge 60 comprises 12 storage sections 30. Of these, six storage sections 30 are for morning use, and the remaining six storage sections 30 are for night use. The six morning storage sections 30 are composed of three storage sections 30 that store odor component A in different component amounts, and three storage sections 30 that store odor component B in different component amounts. The odor components A and B are different odor components. The six night storage sections 30 are composed of three storage sections 30 that store odor component C in different component amounts, and three storage sections 30 that store odor component D in different component amounts. The odor components C and D are different odor components.

[0056] In the morning, the user releases odors from the six morning storage sections 30 in order and smells the odors. Specifically, the user first smells the odors from the three storage sections 30 that store odor component A, one by one, in order of decreasing component amount. The user then records which storage section 30 the odor came from for odor component A, i.e., the strength of the odor that was sensed. This can be recorded by writing it down in a memo, for example. Next, the user smells the odors from the three storage sections 30 that store odor component B, one by one, in order of decreasing component amount. The user then records which storage section 30 the odor came from for odor component B, i.e., the strength of the odor that was sensed.

[0057] Furthermore, at night, the user releases the odor from each of the six nighttime storage units 30 in order and smells the odor. Specifically, the user first smells the odor from each of the three storage units 30 that store odor component C, one by one, in order of decreasing component amount. The user then records which storage unit 30 the odor from, i.e., the strength of the odor, was sensed for odor component C. Next, the user smells the odor from each of the three storage units 30 that store odor component D, one by one, in order of decreasing component amount. The user then records which storage unit 30 the odor from, i.e., the strength of the odor, was sensed for odor component D.

[0058] It is preferable for the user to perform such training every day. By periodically changing the cartridge 60 used, training with different odor components can be performed. This allows the user to continue the training without getting bored. The odor component set 300 does not need to include the retaining part 50. Even if the user purchases the odor component set 300 multiple times, it is not necessary for the user to purchase the retaining part 50 each time, and the user can continue to use the same retaining part 50 once the retaining part 50 is purchased.

[0059] Furthermore, according to the odor output device 10 of this embodiment, the odor can be emitted by a simple operation on the odor output device 10 without using an application on a smartphone or the like. Therefore, even an elderly user can easily use the odor output device 10.

[0060] Furthermore, in the cartridge 60, the multiple storage units 30 may be arranged in a preferred order for releasing the odors (for example, the order used in the preferred olfactory training described above). In the odor output device 10, the order of the multiple operation units 51 may be set so that the odors from the multiple storage units 30 can be released in a preferred order by operating the multiple operation units 51 in the order in which they are arranged.

[0061] In addition, in order to prevent odor from being emitted simultaneously from two or more storage sections 30, the odor output device 10 may have a function that prevents the operating section 51 corresponding to one of the output sections 52 from being turned on while the other output sections 52 are in the ON state.

[0062] In the example of Fig. 3, the odor output device 10 further includes a display unit 53. For example, the display unit 53 displays the elapsed time since any of the output units 52 was turned ON each time the output unit 52 was turned ON. By looking at the time displayed on the display unit 53, the user can know the time it took for the user to start sensing an odor. In addition, by recording the time it took for the user to start sensing an odor for each training session, the change in olfactory function can be understood in more detail.

[0063] Furthermore, the display unit 53 may display information that allows the user to recognize which storage unit 30 is emitting the odor. Alternatively, the operation unit 51 that corresponds to the storage unit 30 that is emitting the odor may emit light so that the user can recognize which storage unit 30 is emitting the odor.

[0064] Fig. 7 is a cross-sectional view illustrating an odor output device 10 according to Modification 1. In the odor output device 10 according to Modification 1, the odor output device 10 further includes a lid 54. The lid 54 covers at least a portion of the cartridge 60 held in the holding portion 50. Fig. 5 shows an example in which the odor output device 10 is used with at least a portion of the cartridge 60 exposed. On the other hand, in the example of Fig. 7, the odor output device 10 is used with the entire cartridge 60 not exposed.

[0065] Lid 54 is provided with one or more holes 540. When hole 540 and hole 610 are in communication with each other, they function as an odor emission hole. The emission hole formed by hole 540 and hole 610 communicating with each other connects storage space 310 with the outside. In this way, hole 610 can function as at least a part of an odor emission hole.

[0066] The lid 54 may have a hole 540 for each storage section 30, or may have only one hole 540. When the lid 54 has only one hole 540, the hole 540 may be switched between a state in which the hole 540 communicates with any of the holes 610 and a state in which the hole 540 does not communicate with any of the holes 610. For example, the user may be able to switch between a state in which the hole 540 communicates with any of the holes 610 and a state in which the hole 540 does not communicate with any of the holes 610 by rotating the lid 54 with respect to the cartridge 60 about the Z axis. When the user wants to release an odor from any of the storage sections 30, the user causes the hole 610 of that storage section 30 to communicate with the hole 540. By doing so, it is possible to block odors from other than that storage section 30. When the user wants to release an odor from none of the storage sections 30, the user may not cause the hole 540 to communicate with any of the holes 610. By doing so, it is possible to close the storage space 310 from the outside.

[0067] 8 is a cross-sectional view illustrating an odor output device 10 according to Modification 2. In Modification 2, the storage section 30 is detachable from the connection section 620. In this modification, a cartridge 60 can be formed by attaching a plurality of storage sections 30 containing odor components to the connection section 620. In addition, by removing a storage section 30 after use from the connection section 620 and attaching a new storage section 30 to the connection section 620, the connection section 620 can be used repeatedly.

[0068] In this modification, connection part 620 is provided with hole 610 for each storage part 30. When storage part 30 is attached to connection part 620, hole 301 provided in storage part 30 and hole 610 of connection part 620 communicate with each other to form an odor release hole.

[0069] In this modified example, the odor component set 300 may not include the connection part 620. For example, the multiple storage parts 30 included in the odor component set 300 may be in an unconnected state. A user who obtains the odor component set 300 can attach the multiple storage parts 30 to the connection part 620 to form a cartridge 60 for use.

[0070] Meanwhile, in this modified example, the odor component set 300 may include a connection unit 620. For example, the work of attaching a plurality of storage units 30 containing odor components to the connection unit 620 is performed before shipping the odor component set 300. In this way, the odor components and the amounts of the components can be efficiently customized to suit each user.

[0071] The odor output device 10 according to this modification may include a lid 54, similar to the odor output device 10 according to the first modification.

[0072] According to this embodiment, the same action and effect as the first embodiment can be obtained. In addition, according to this embodiment, the holding unit 50 holds a plurality of storage units 30 that store odor components. Therefore, it is possible to easily output odors from a plurality of storage units 30.

[0073] (Third embodiment) 9 is a diagram illustrating the functional configuration of the odor output device 10 according to the third embodiment. The odor output device 10 according to this embodiment is the same as the odor output device 10 according to the second embodiment, except for the points described below. In FIG. 9, the dashed lines indicate that the operation of the output unit 52 acts on the storage unit 30, as described in the second embodiment.

[0074] The odor output device 10 according to this embodiment includes a control unit 55. The control unit 55 controls the output of odor from the output unit 52. The control unit 55 causes odors to be output from the multiple storage units 30 in sequence based on a predetermined pattern.

[0075] Furthermore, the odor output device 10 is provided with an operation unit 51 corresponding to each of the multiple patterns. The operation unit 51 is, for example, a switch. In the example of FIG. 9, the odor output device 10 is provided with two operation units 51. However, the number of operation units 51 is not particularly limited. By providing the odor output device 10 with the operation units 51 corresponding to each of the multiple patterns, the odor output device 10 can easily generate odor in each pattern.

[0076] 9, the odor output device 10 further includes a pattern storage unit 550. The pattern storage unit 550 stores a plurality of pieces of pattern information indicating patterns in advance. The control unit 55 reads out the pattern information corresponding to the operated operation unit 51 from the pattern storage unit 550, and uses it to control one or more output units 52. The pattern storage unit 550 may be provided outside the odor output device 10.

[0077] In the example of FIG. 9, the odor output device 10 includes a drive circuit 56 for driving the output unit 52. The control unit 55 outputs a control signal based on the pattern information, and the control signal is input to the drive circuit 56. The drive circuit 56 outputs a drive signal for driving the output unit 52 in response to the control signal from the control unit 55. When the drive signal is input to the output unit 52, the output unit 52 is driven, and an odor is output from the storage unit 30. Note that the odor output device 10 may include only one drive circuit 56. In that case, the control unit 55 may output a control signal for switching the output destination of the drive signal from the drive circuit 56.

[0078] The hardware configuration of the control unit 55 will be described below. The control unit 55 may be realized by hardware that realizes the control unit 55 (e.g., a hardwired electronic circuit, etc.), or may be realized by a combination of hardware and software (e.g., a combination of an electronic circuit and a program that controls the electronic circuit, etc.). The case where the control unit 55 is realized by a combination of hardware and software will be further described below.

[0079] 10 is a diagram illustrating an integrated circuit 40 for implementing the control unit 55. The integrated circuit 40 is, for example, a SoC (System On Chip).

[0080] The integrated circuit 40 has a bus 402, a processor 404, a memory 406, a storage device 408, an input / output interface 410, and a network interface 412. The bus 402 is a data transmission path for the processor 404, the memory 406, the storage device 408, the input / output interface 410, and the network interface 412 to transmit and receive data to and from each other. However, the method of connecting the processor 404 and the like to each other is not limited to bus connection. The processor 404 is an arithmetic processing device realized by using a microprocessor or the like. The memory 406 is a memory realized by using a RAM (Random Access Memory) or the like. The storage device 408 is a storage device realized by using a ROM (Read Only Memory), a flash memory, or the like.

[0081] The input / output interface 410 is an interface for connecting the integrated circuit 40 to peripheral devices. In this figure, one or more operation units 51 and one or more drive circuits 56 are connected to the input / output interface 410.

[0082] The network interface 412 is an interface for connecting the integrated circuit 40 to a communication network. This communication network is, for example, a LAN (Local Area Network) or a WAN (Wide Area Network). The network interface 412 may be connected to the communication network by wireless connection or by wired connection. When the pattern storage unit 550 is provided outside the odor output device 10, the control unit 55 may acquire pattern information from the pattern storage unit 550 through the communication network. However, the integrated circuit 40 does not need to include the network interface 412.

[0083] The storage device 408 stores program modules for realizing the functions of the control unit 55 respectively. The processor 404 reads out and executes this program module in the memory 406, thereby realizing the functions of the control unit 55. Further, when the pattern storage unit 550 is provided inside the odor output device 10, for example, the pattern storage unit 550 is realized using the storage device 408.

[0084] FIG. 11 is a timing chart showing an example of a pattern for outputting odors from a plurality of storage units 30. The pattern for outputting odors from the plurality of storage units 30 will be described in detail below.

[0085] In the example of FIG. 11, for six storage units 30 (storage unit A1, storage unit A2, storage unit A3, storage unit B1, storage unit B2, and storage unit B3), the ON / OFF timing of odor output is shown. Among the six storage units 30, three storage units 30 (storage units A1 to A3) store odor component A, and the remaining three storage units 30 (storage units B1 to B3) store odor component B. Odor component A and odor component B are different odors from each other. For storage unit A1, storage unit A2, and storage unit A3, the component amounts are V1a, V2a, and V3a respectively. The relationship V1a < V2a < V3a holds for these component amounts. For storage unit B1, storage unit B2, and storage unit B3, the component amounts are V1b, V2b, and V3b respectively. The relationship V1b < V2b < V3b holds for these component amounts.

[0086] The time when the operation unit 51 corresponding to this pattern is operated (turned ON) is defined as time t0. When the operation unit 51 is operated, the control unit 55 starts the odor output from the storage unit A1. When time T1 has elapsed since starting the odor output from the storage unit A1, the control unit 55 stops the odor output from the storage unit A1 and starts the odor output from the storage unit A2. When time T2 has elapsed since starting the odor output from the storage unit A2, the control unit 55 stops the odor output from the storage unit A2 and starts the odor output from the storage unit A3. When time T3 has elapsed since starting the odor output from the storage unit A3, the control unit 55 stops the odor output from the storage unit A3.

[0087] The control unit 55 may provide a period during which no odor is output from any of the storage units 30 between the time when the odor output from the storage unit A1 is stopped and the time when the odor output from the storage unit A2 is started. However, the length of this period is the length T of the blank period described later. b Similarly, the control unit 55 may provide a period during which no odor is output from any of the storage units 30 between the time when odor output from the storage unit A2 is stopped and the time when odor output from the storage unit A3 is started. However, the length of this period is shorter than the length T b is shorter than.

[0088] After the odor output from the storage section A3 is stopped, the time T b During the time period (blank period) until the time has elapsed, the control unit 55 does not cause any of the storage units 30 to output odor.

[0089] After the odor output from the storage section A3 is stopped, the time T bWhen time T4 has elapsed since starting odor output from storage unit B1, control unit 55 stops odor output from storage unit B1 and starts odor output from storage unit B2. When time T5 has elapsed since starting odor output from storage unit B2, control unit 55 stops odor output from storage unit B2 and starts odor output from storage unit B3. When time T6 has elapsed since starting odor output from storage unit B3, control unit 55 stops odor output from storage unit B3. This ends the pattern.

[0090] The control unit 55 may provide a period during which no odor is output from any of the storage units 30 between the time when the odor output from the storage unit B1 is stopped and the time when the odor output from the storage unit B2 is started. However, the length of this period is equal to or longer than the length T of the blank period. b Similarly, the control unit 55 may provide a period during which no odor is output from any of the storage units 30 between the time when odor output from the storage unit B2 is stopped and the time when odor output from the storage unit B3 is started. However, the length of this period is shorter than the length T of the blank period. b is shorter than.

[0091] As shown in an example in Fig. 11, the odor output pattern is preferably configured so that the concentration of the odor output from the odor output device 10 increases in sequence for each odor component. This is because if a person becomes accustomed to smelling a stronger odor first, he or she may have difficulty sensing weaker odors that follow.

[0092] When the multiple storage sections 30 further include a third storage section 30 containing a second odor component (odor component B) different from the first odor component (odor component A), as shown in an example in FIG. 11, the odor output pattern is preferably configured so that a blank period in which neither odor is output occurs between the period in which the first odor component is output from the odor output device 10 and the period in which the second odor component is output from the odor output device 10. The length T of the blank period bis not particularly limited, but is, for example, from 10 to 900 seconds, preferably from 10 to 600 seconds, and more preferably from 10 to 300 seconds. By doing so, mixing of odors can be reduced when the odor components are switched.

[0093] The times (T1, T2, T3, T4, T5, and T6) for outputting the odor may be the same or different for the multiple storage sections 30. The time for outputting the odor for each storage section 30 is not particularly limited, but is, for example, from 10 to 600 seconds, preferably from 10 to 300 seconds, and more preferably from 10 to 60 seconds.

[0094] The following describes an example of how a user uses the odor output device 10 according to this embodiment. The odor output device 10 can include, for example, an operation unit 51 corresponding to a morning pattern and an operation unit 51 corresponding to an evening pattern.

[0095] The six storage sections 30 used in the morning pattern and the six storage sections 30 used in the night pattern are different from each other. For example, in the morning pattern, in the example described with reference to FIG. 11, three storage sections 30 containing a grapefruit odor component as odor component A and three storage sections 30 containing a peppermint odor component as odor component B are used. In the morning pattern, it is preferable that an odor that motivates the user is output. On the other hand, in the night pattern, in the example described with reference to FIG. 11, three storage sections 30 containing a lavender odor component as odor component A and three storage sections 30 containing a rose odor component as odor component B are used. In the night pattern, it is preferable that an odor that relaxes the user is output.

[0096] Every morning, the user operates (turns ON) the operation unit 51 corresponding to the morning pattern. Then, odors are output from the six morning storage units 30 in sequence in the pattern shown in FIG. 11. The user smells the output odors in sequence. In order to confirm the effect of training, it is preferable for the user to record how the odors were perceived, such as which storage unit 30 the odor was smelled from.

[0097] Every night, the user operates (turns ON) the operation unit 51 corresponding to the night pattern. Then, odors are output from the six night storage units 30 in sequence in the pattern shown in FIG. 11. The user smells the output odors in sequence. In order to confirm the training effect, it is preferable for the user to record how they sense the odor, such as which storage unit 30 the odor was smelled from.

[0098] Next, the action and effect of this embodiment will be described. In this embodiment, the same action and effect as in the first embodiment can be obtained. In addition, according to this embodiment, the control unit 55 sequentially outputs odors from the multiple storage units 30 based on a predetermined pattern. Therefore, the user can easily output multiple odors in a predetermined pattern.

[0099] Although the embodiments of the present invention have been described above with reference to the drawings, these are merely examples of the present invention, and various configurations other than those described above may also be adopted. Furthermore, the above-described embodiments may be combined within a range in which the contents are not contradictory. [Explanation of symbols]
