Description

The present invention relates to a mobile phone .

  Conventionally, various fragrance products have been provided for the purpose of sedation, sleep falling, awakening, analgesic, antibacterial, deodorant and the like. Among these fragrance products, those using so-called essential oils include a heating system that heats essential oil (or a solution containing it or a sheet soaked with the solution) to volatilize the fragrance, and does not heat the essential oil. There is a non-heating method that volatilizes naturally.

  As an unheated fragrance product, one having a bottle filled with a solution in which a fragrance is dissolved and a volatilization part that sucks up the solution in the bottle and volatilizes it to the outside is known. In addition, a sheet-like fragrance product containing a fragrance (hereinafter sometimes referred to as “fragrance sheet”) is also known. As an aromatic sheet, for example, a sheet in which a microcapsule containing an aromatic component is attached to a substrate is known (see Patent Document 1). In the fragrance sheet disclosed in Patent Document 1, the microcapsule is broken by applying pressure, whereby the fragrance component is volatilized to the outside of the fragrance sheet. Further, as a product having a function and configuration similar to an aromatic sheet, a so-called mosquito-removing mat that volatilizes a volatile insecticidal component soaked into the sheet by heating with an electric warmer is known.

  On the other hand, a mobile phone with an aromatic function has been proposed so that a user can use the mobile phone comfortably. For example, a mobile phone in which an aromatic member made of a coating layer is detachably attached to a mobile phone body has been proposed (see Patent Document 2). In addition, there has been proposed a mobile phone that includes a vibration generating device that notifies an incoming call and has an aromatic member attached to the vibration generating device (see Patent Document 3). Furthermore, in a folding mobile phone, an insertion chamber is formed inside the piece portion constituting the hinge mechanism so that one end is open and an aroma member can be inserted and removed. There has been proposed a mobile phone provided with a plurality of small holes leading to a charging chamber at a position exposed by the above (see Patent Document 4).

  However, since the cellular phones shown in Patent Documents 2 to 4 have an aroma function, the user can enjoy a comfortable aroma. However, in the mobile phone shown in Patent Document 2, the fragrance component is always volatilized from the fragrance member made of the coating layer. For this reason, even when the user does not use the mobile phone, the fragrance component is wasted and the use efficiency of the fragrance component is very low. Moreover, in the mobile phone shown in Patent Document 3, the fragrance component is forcibly evaporated by vibration at the time of incoming call. However, also in this case, since the fragrance component is always volatilized without applying vibration to the fragrance member, the utilization efficiency of the fragrance component is very low.

  In addition, in the meaning of the improvement of the utilization efficiency of an aroma component, utilization of the aroma sheet illustrated in patent document 1 is also considered as an aroma member. However, in order to volatilize the fragrance component to the outside, it is necessary to rub or press the fragrance sheet surface. Such an action is completely unrelated to an action necessary for demonstrating the main function of the electronic device (for example, pressing a call push button in the case of a mobile phone). The fragrance function is not a function that the user actively uses with a purpose, such as an incidental function such as a TV function or a game function of a mobile phone, in addition to the main function. This is basically a function for users to enjoy passively. Considering these points, in order to utilize the fragrance function, the user must be actively forced to perform an action (scrubbing and holding) that is separate from the action necessary to demonstrate the main function. Low practicality. That is, it is not meaningful to use the fragrance sheet disclosed in Patent Document 1 to daringly provide an electronic device with an fragrance function.

  On the other hand, the foldable mobile phone shown in Patent Document 4 can vaporize fragrance components to the outside only when opened. However, since it is necessary to provide a loading chamber into which the fragrance member can be inserted and removed, the hinge mechanism becomes large. As described above, in the conventional electronic device having a fragrance function, there is a problem in that the use efficiency of the fragrance component is low because the fragrance component is always volatilized, and the size of the electronic device is increased.

The present invention has been made in view of the above circumstances. That is, the first aspect of the present invention can suppress an increase in size even if it has an aroma function, has a high use efficiency of an aroma component, and is linked with an action necessary for exhibiting a function other than the aroma function. It is an object of the present invention to provide a mobile phone capable of exerting an aromatic function.

In addition, the second aspect of the present invention can suppress an increase in size even if it has a fragrance function, has a high use efficiency of a fragrance component, and is automatically linked with communication information when it is received. It is an object to provide a mobile phone capable of exhibiting an aromatic function.

<First invention>
The first aspect of the present invention will be described below.
The electronic device according to the first embodiment (including “mobile phone” as one embodiment of the electronic device, the same applies hereinafter) controls at least one selected from the fragrance sheet, the electronic device main body, and the fragrance sheet. One or more control means, and the fragrance sheet is a gas-permeable sheet-like base material, and one or more ones for selectively heating a partial region in the planar direction of the sheet-like base material A heating element and a microcapsule that is disposed at least in the vicinity of the heating element and includes a core material containing an aromatic component and an outer shell material that covers the core material and is destroyed by heating. When a control signal for volatilizing the fragrance component to the outside is input by a control means having a function of controlling the sheet, heating is performed in at least one heating region to volatilize the fragrance component to the outside. It is characterized in.

  The electronic device according to the first embodiment includes a fragrance sheet that volatilizes fragrance components to the outside. For this reason, in addition to the function originally possessed by the electronic device, it also has a function of volatilizing the fragrance component to the outside (hereinafter sometimes abbreviated as “fragrance function”). And since this aromatic sheet is a sheet form, it can be arrange | positioned by attaching to the surface of an electronic device, etc., and is excellent in space-saving property. For this reason, the enlargement of an electronic device can be suppressed. In addition, since the fragrance component is encapsulated in the microcapsule unless heated by the heating element, the fragrance component does not always evaporate. And when the user of an electronic device wants to volatilize a fragrance component, what is necessary is just to give the signal which heats a specific heating area | region to a fragrance sheet via a control means. For this reason, since a fragrance component will volatilize only when a user operates and uses an electronic device, the utilization efficiency of a fragrance component is high.

  Further, the electronic apparatus of the first embodiment includes one or more control means. And this control means may control only an electronic device main body, may control only a fragrance sheet, and may control both simultaneously. Therefore, the control means for controlling the electronic device main body can also serve as a function for controlling the heating of the heating element of the fragrance sheet. For example, if the electronic device is a mobile phone, when the call push button (control means) is pressed, a signal for instructing heating by the fragrance sheet heating element is also sent to the fragrance sheet heating element (or this). It can be transmitted to a control circuit to be controlled. In this case, if the call push button is pressed, the user can enjoy the scent at the same time as making a call. As described above, in the electronic device according to the first embodiment, it is possible to exhibit the fragrance function in conjunction with an action necessary for exhibiting a function other than the fragrance function.

  In addition, “an action necessary for exhibiting a function other than the fragrance function” means not only an action necessary for directly exhibiting the function but also a preparatory action necessary for exhibiting the function. For example, taking a mobile phone as an example, an act of pushing a call push button corresponds to an action necessary to directly exert a call function. Moreover, the act of preparatory action necessary for demonstrating the telephone call function includes the action of pushing the power push button. In this case, the power-off state (completely stopped state) is changed to the power-on state (standby state in which the call function can be exhibited at any time by pressing the call push button). In the case of a foldable mobile phone, the act of opening the mobile phone also corresponds to a preparatory action necessary for exhibiting the call function.

  Also, taking as an example a CD player equipped with a tray for inserting / ejecting a CD into / from the main body, the necessary action for directly exerting the call function is that the power is on and the CD is turned on. In the state of being inserted into the main body, the action of pressing the playback push button or pressing the push button for releasing the pause of playback will be on the street. In addition, the preparatory action required to bring out the playback function is an action of pressing the power push button to turn on the power, or a key for operating the tray in order to insert the CD into the main body. This corresponds to an act of pressing (specifically, an act of pressing a key when inserting a tray).

-Control means-
The control means is not particularly limited as long as it is a known control means, but typically, a substantive control means that can be directly operated by a human, such as a push button, a knob, a lever, or a push button displayed on a touch panel. Is mentioned. In addition, a virtual control means such as a push button displayed on the display, which is a virtual input means (for example, a mouse, a touch pad, a cursor key, etc.) controlled by a substantial input means (for example, Also, virtual control means that can be turned ON / OFF by a pointer that is displayed on a display and moves in conjunction with a mouse or the like.

  Note that the control means is not limited to the control means originally provided with the intention of controlling the functions of the electronic device and the power ON / OFF, such as the above-described push buttons. For example, when the electronic device can be manually and reversibly deformed into two or more different shapes, the deformation operation from one shape to another shape may function as the control means. For example, in a foldable mobile phone that can be reversibly deformed into a closed shape and an open shape, the deformation operation from the closed shape to the open shape may function as a control means.

  In addition, one control means may exhibit only one function, but may exhibit two or more functions simultaneously or at different timings. For example, in the case of a cellular phone, any one push button has both a function to turn on the power, a function to turn off the power, and a function to disconnect the call, and the other push buttons As a specific example, there is a case in which a function for starting a fragrance and a fragrance function for volatilizing a fragrance component simultaneously with the start of a call are provided. Further, the control means having a function of controlling the fragrance sheet does not mean only a function having a function of controlling from a state where the fragrance function is not exhibited to a state where the fragrance function is exhibited, but from a state where the fragrance function is exhibited. What has the function to control to the state which cancels this state from the state which is scheduled to exhibit the function which controls the state which is not exhibited, or an aroma function is also included. The control means having the function of controlling the fragrance sheet has at least one of these functions, and may have two or more functions.

-Aspects of electronic equipment-
The electronic device of the first embodiment may be any electronic device such as a refrigerator or a washing machine as long as it is a known electronic device. However, from the viewpoint of enjoying the fragrance that is volatilized from the fragrance sheet provided on the electronic device, the electronic device must be placed in the user's close proximity or on the user when operating or using the electronic device. It is preferable to use, and it is preferable that it is a portable electronic device especially. As such a portable electronic device, for example, a mobile phone, a conversation device (a so-called fixed telephone handset, a headset used by being connected to a PC, etc.) integrally provided with a speaker and a microphone, Headphones, personal digital assistants (PDAs), notebook PCs, and portable information reproducing devices having at least a function of reproducing at least one selected from audio information and image information, shaving machines, and the like can be given. Note that the sound information means information that can be recognized by hearing such as music (including those accompanying image information such as movies), conversation, speech, and reading. Here, the image information means information that can be visually recognized, such as moving images such as movies, still images such as photographs and documents.

  In addition to the call function, the mobile phone has various sub-functions such as an e-mail function, an imaging function, a terrestrial digital TV broadcast display function (so-called one-segment reception function), and a voice recording / playback function (so-called music player, IC recorder function, etc.). It may have the following functions. When the mobile phone has secondary functions such as a digital terrestrial television broadcast display function and a voice recording / playback function, the mobile phone also functions as a portable information playback device. Further, as a specific example of the portable information reproducing device, for example, a portable information reproducing device that reproduces audio information and image information recorded on an external recording medium (recording medium) such as a portable semiconductor memory such as a CD, DVD, Blu-ray, or SD card. Mainly for type players (portable media players), portable players (players with built-in portable memory) that reproduce audio and image information recorded in built-in memories such as hard disks and semiconductor memories, and image information (especially still images) Examples include so-called electronic paper, electronic books, and electronic dictionaries to be reproduced. In the present invention, among these electronic devices, portable electronic devices that are often used while being worn or in close proximity to the face; that is, mobile phones or portable players are particularly preferable.

-Outline of fragrance sheet-
The fragrance sheet used in the electronic apparatus of the first embodiment includes a sheet-like base material having air permeability, a heating element that selectively heats a partial region of the sheet-like base material, and at least the heating element. And a microcapsule that is disposed in a heating region that is selectively heated and includes a core material containing an aromatic component and an outer shell material that covers the core material and is destroyed by heating. Then, when a control signal for volatilizing the fragrance component is input to the outside by a control unit having a function of controlling at least the fragrance sheet, heating is performed in at least one heating region selected from all the heating regions. , It has a function of volatilizing the fragrance component to the outside.

  The fragrance sheet can be arranged at any position of the electronic device, but it is usually preferable to arrange it on the surface of the casing of the electronic device. In this case, the fragrance sheet may be exchangeably attached to the surface of the housing. For example, if the external panel is a replaceable mobile phone (so-called dress-up mobile phone), the fragrance sheet may be attached to the external panel, or the entire external panel may be composed of the fragrance sheet. Moreover, the outer wall material itself which comprises the housing | casing surface may be comprised from the fragrance sheet. Furthermore, the aromatic sheet arrange | positioned at an electronic device is not limited to only one, Two or more may be sufficient. It does not specifically limit as a planar shape of an aromatic sheet, It can be set as arbitrary shapes. For example, in the case where an aroma sheet is provided on a flat surface surrounding the periphery of a mobile phone display, a square ring shape can be used.

  The number of heating regions of the fragrance sheet (when two or more fragrance sheets are used in the electronic device), the total number of heating regions in all fragrance sheets may be at least one, but usually two or more. It is preferable that When the number of heating regions is at least 2 or more, the heating / non-heating control of each heating region is controlled independently, so that the fragrance component is volatilized to the outside in two or more times over time. Can do. In addition, the fragrance intensity can be adjusted by controlling the number of heating regions that are heated simultaneously.

  Further, when the fragrance sheet has two or more heating regions, the first fragrance component is included in the microcapsules arranged in one heating region, and the first in the microcapsules arranged in the other heating region. You may make it include the 2nd aroma component of a kind different from this aroma component. In this case, by controlling the timing of heating one heating region and the other heating region, after volatilizing the first fragrance component, volatilize the second fragrance component, After volatilization, the first aroma component can be volatilized, or the first aroma component and the second aroma component can be volatilized simultaneously. For this reason, the user of an electronic device can enjoy several fragrances with various patterns.

  The number of heating regions can be selected as appropriate according to the type of electronic device and its usage. For example, in the case where the electronic device is a mobile phone, consider a case where the usage mode is to make a call twice on average per day. Here, it is assumed that the call push button also has a function of controlling the fragrance sheet, and the fragrance intensity sufficient for the user to sense the fragrance can be obtained by simultaneously heating the two heating regions. In this case, if the number of heating areas provided in the fragrance sheet is about 4500, the user can scent the fragrance every time they call without performing maintenance work such as replacement of the fragrance sheet over a long period of about 3 years. Can enjoy. That is, the fragrance sheet used in the electronic device of the first embodiment is disclosed in Patent Documents 2 and 3 by appropriately selecting the number of heating regions according to the type and usage of the electronic device. It is easy to maintain the fragrance function over a long period of time as compared to the fragrance member used in a conventional mobile phone having a fragrance function as a secondary function. For this reason, the user of the electronic device is not forced to replace the fragrance member within a short period of time.

  Heating of the heating region by the heating element is performed when a control signal for volatilizing the fragrance component to the outside is input by at least the control means for controlling the fragrance sheet. In this case, the heating / non-heating control of the heating region can be directly controlled by the control means. However, when the number of heating regions is two or more and heating / non-heating control is performed in units of individual heating regions, it is usually preferable to perform the control via a control circuit such as an IC chip. In this case, for example, heating / non-heating control of the heating region can be performed as follows. First, when a control signal for volatilizing the fragrance component to the outside is input by the control means, this control signal is transmitted to the control circuit. Here, the control circuit discriminates between a heating region in which heating has already been performed and a heating region in which heating has not been performed yet. This discrimination work can be performed, for example, with reference to the heating history of each heating area recorded in the memory. Then, after selecting one or a plurality of heating regions from among the heating regions that have not yet been heated, the heating region is turned on only for a time required for destroying the microcapsules by heating. A control signal is transmitted from the control circuit to the fragrance sheet. As a result, heating is performed in one or a plurality of heating regions, so that the microcapsules arranged in the heating region are destroyed by heating, and the fragrance component is volatilized to the outside. Here, the heating / non-heating control procedure of the heating region via the heating element by the control circuit described above can be programmed in advance. Thus, for example, after a control signal is input by the control means, the fragrance function is exhibited after a certain period of time, or when the control signal input by a plurality of control means is a specific combination. This makes it easy to perform complex control such as demonstrating. Although the outline of the fragrance sheet has been described above, details of constituent materials of each part constituting the fragrance sheet and a specific structure will be described later.

-First embodiment-
Next, a case where at least one substantive control means selected from a knob, a lever, and a push button displayed on the touch panel is used as a control means for controlling at least the fragrance sheet will be described in more detail (hereinafter referred to as “control means”). The electronic device of this aspect may be referred to as “the electronic device of the first embodiment”). In the description of the first embodiment, the control means is described on the assumption that a push button is used. However, the control means is not limited to the push button. In this case, the fragrance function may be controlled independently of other functions of the electronic device and power ON / OFF, but normally, the fragrance function is exhibited in conjunction with the other functions of the electronic device and power ON / OFF. It is preferable. As a specific example of the latter case, (1) the fragrance is linked with the case where the electronic device is turned off (completely stopped) to a state where a specific function of the electronic device can be performed at any time (standby state). A mode for exerting a function, (2) A mode for exerting an aroma function in conjunction with a state in which a specific function of an electronic device is exhibited from a standby state, (3) A specification of an electronic device from a completely stopped state A mode in which the fragrance function is exerted in conjunction with the state where the function is exhibited, (4) A mode in which the fragrance function is performed in conjunction with the transition from the standby state to the complete stop state, (5) Other than the fragrance function From a state in which a specific function is exhibited, to a state in which the aroma function is exhibited in conjunction with a standby state, or (6) from a state in which a specific function other than the aroma function is exhibited, to a complete stop state Place to do In conjunction with the like manner to exhibit fragrance features are exemplified by.

  Among the embodiments shown in (1) to (6), embodiments (1) to (2) are preferable, and embodiment (2) is particularly preferable. As a specific example of the aspect (1), it is possible to exhibit an aroma function in conjunction with a switch from a power-off state to a power-on state by pressing a push button having a function of turning on the power. Further, in a media player such as a CD player or a DVD player having a mechanism for loading / unloading media, the media is loaded and stored in the media player main body by pressing a push button having a function of loading the media. The fragrance function can be exhibited in conjunction with the case.

  As a specific example of the aspect (2), in the case of an information reproduction player that reproduces at least one information selected from audio information and image information such as a CD player or a DVD player, for example, it is linked to pressing a reproduction push button. And the case where the aromatic function is exhibited. In addition, the information reproducing player normally does not operate even when all push buttons are pressed (a so-called hold key. For example, a slide switch or a push button that exhibits a hold function by long-pressing a specific key). It has. In this case, the fragrance function can be exhibited in conjunction with the switch being turned off (the state in which the hold function is turned off) (the fragrance component is volatilized to the outside). In the case of a mobile phone having a push button having a function for starting a call, for example, when the hold function is turned OFF in conjunction with a long press of a push button having a function for starting a call (fragrance component) The fragrance function can be exhibited.

  In addition, when the electronic device has two or more functions other than the fragrance function (however, the “function” mentioned here excludes the function of simply turning on / off the power), one of the functions is exhibited. The fragrance function may be exhibited only in conjunction with pressing of the push button, or the fragrance function may be exhibited in conjunction with pressing of the push button exhibiting each function. In the latter case, the fragrance intensity can be different for each function. For example, in a mobile phone having a digital terrestrial television broadcast display function in addition to a call function, only when a push button that exerts one of the functions is pressed, the fragrance function is exhibited in conjunction with this. Alternatively, when each of the push buttons that exert both functions is pressed, the fragrance function may be exhibited in conjunction with this.

  Furthermore, the fragrance sheet has two or more heating regions, the first fragrance component is encapsulated in the microcapsules arranged in one heating region, and the first in the microcapsules arranged in the other heating region. When a second fragrance component of a different type from the fragrance component is included, the first fragrance component is volatilized in conjunction with pressing a push button that demonstrates one function, and the other functions are performed. The second fragrance component may be volatilized in conjunction with pressing the push button. For example, in a mobile phone having a terrestrial digital TV broadcast display function in addition to a call function, when a push button for activating the call function is pressed, the scent of jasmine is volatilized as the first fragrance component. When a push button for demonstrating a television broadcast display function is pressed, the scent of citrus mint can be exhibited as the second fragrance component.

-Second embodiment-
Next, a case where the electronic device can be reversibly deformed to at least two different shapes manually will be described. In this case, the deformation operation from one shape to another shape can be caused to function as a control means for controlling at least the fragrance sheet. In other words, the fragrance function can be exhibited in conjunction with the deformation operation from one shape to another shape (the fragrance component is volatilized to the outside) (hereinafter, the electronic device of this aspect is referred to as “the second embodiment”). Sometimes referred to as "electronic equipment"). Here, when the electronic device can be reversibly deformed manually into two or more different shapes, at least two or more deformation operations exist. For example, when it can be reversibly deformed into two different shapes, there is a deformation operation from the first shape to the second shape, and a deformation operation from the second shape to the first shape. To do. In this way, when there are two or more deformation operations, the fragrance function may be exhibited in conjunction with only one of the deformation operations, or the fragrance function may be associated with two or more or all of the deformation operations. It may be demonstrated. In addition, in the latter case, the expression of the fragrance function is not limited to the mode in which the fragrance component is volatilized from the state in which the fragrance component is not volatilized in accordance with the deformation operation from one shape to the other shape. The aspect which changes the intensity | strength and the state made into the state which volatilizes another aromatic component from the state which volatilizes one aromatic component are also contained.

  For example, in the case of a foldable mobile phone that can be reversibly deformed into a closed shape and an open shape, the fragrance function is linked to the deformation operation from the closed shape to the open shape when the power is turned on. Can be demonstrated. Also, it is transformed into a closed shape, a shape opened in the vertical direction (for the purpose of telephone calls, etc.), and a shape opened in the horizontal direction (for the purpose of viewing digital terrestrial television broadcasting, etc.). In the case of a mobile phone that can be deformed reversibly between any two shapes selected from three shapes, in the state where the power is turned on, for example, the following (1) to (4) The fragrance function can be exhibited in conjunction with at least one of the deformation operations as illustrated in FIG. That is, (1) Deformation operation from a closed shape to a vertically open shape, (2) Deformation operation from a closed state to a horizontally open shape, and (3) Transversely open shape to a vertical direction And (4) a deformation operation from a shape opened in the vertical direction to a shape opened in the horizontal direction. When receiving a TV broadcast by pressing a push button having a function of displaying a terrestrial digital television broadcast (hereinafter sometimes abbreviated as a “one seg button”) in a state of being opened horizontally, for example, a mode ( After the deformation operation shown in 2) or (4), when the one seg button is pressed and there is no deformation operation from the laterally opened state to the vertically opened state or closed state within a certain time, Complex control such as exerting an aroma function may be performed. In this case, after the one seg button is pressed, the deformation operation performed within a predetermined time functions as a control unit that cancels the performance of the fragrance function in the fragrance sheet.

  In addition, when exhibiting an aroma function in conjunction with all the deformation | transformation operation | movement shown to aspect (1)-(4), for example, aspect (1) is the fragrance (for example, jasmine) from an odorless state to a 1st aromatic component. ), And in the aspect (2), the fragrance of the second fragrance component (for example, citrus mint) is fragranced from the odorless state, and in the aspects (3) and (4), the fragrance is fragrant. The type can be changed (eg, jasmine to citrus mint, or citrus mint to jasmine).

-Details of fragrance sheet-
Next, the function and effect of the fragrance sheet used in the electronic apparatus of the first embodiment, each member constituting the fragrance sheet, the structure / production method of the fragrance sheet, operation, and the like will be described. The fragrance sheet uses a microcapsule that includes a core material containing an fragrance component and an outer shell material that covers the core material and is destroyed by heating. For this reason, when the microcapsule is heated in the heating region, the outer shell material is destroyed, whereby the fragrance component is volatilized outside the fragrance sheet. Therefore, the aromatic component can be volatilized without using a mechanical method such as a pressing force. Furthermore, since the fragrance component is encapsulated in the microcapsule, the fragrance component is not volatilized and lost naturally unless the microcapsule is heated from the outside. For this reason, even when the fragrance sheet is always in contact with the outside air when not in use, the fragrance performance does not deteriorate.

-Aromatic ingredients-
The fragrance component used in the fragrance sheet is not particularly limited as long as the component has fragrance in a general temperature environment (about −10 ° C. to 50 ° C.) in which the use of the fragrance sheet is assumed, Known aromatic substances can be used. The fragrance component may be a mixture of two or more fragrance substances. Furthermore, the fragrance component used may have an antibacterial function in addition to the fragrance function. In addition, as a fragrance component, if it is a well-known fragrance component, it can utilize without a restriction | limiting especially, For example, an essential oil, a synthetic | combination fragrance | flavor, an animal fragrance | flavor, these active ingredients, a simple substance compound etc. are mentioned suitably, The active ingredient contained is preferred.

Moreover, you may use combining these active ingredients in multiple numbers.

-Microcapsules-
The microcapsule used for the fragrance sheet can be produced by using a known microcapsule production method. The microcapsule production method can be roughly classified into a chemical method, a physicochemical method, and a mechanical method. And (1) chemical methods include, for example, suspension polymerization method, miniemulsion polymerization method, emulsion (emulsion) polymerization method, precipitation polymerization method, dispersion polymerization method, interfacial polymerization method, submerged curing method, (2) Examples of the physicochemical method include a submerged drying method, a phase inversion emulsification method, and a coacervation method. (3) Examples of the mechanical method include a spray drying method and a heteroaggregation method. (See, for example, "Key Points for Nano / Microcapsule Adjustment", Hayato Tanaka, Techno System Co., Ltd.)

  Among these microencapsulation methods, the interfacial polymerization method and the coacervation method are usually preferred. When the interfacial polymerization method is used, the microcapsules can be manufactured, for example, as follows. First, an oil phase prepared by dissolving or dispersing an aromatic component in a hydrophobic organic solvent as a raw material constituting a core material of a microcapsule is prepared. Next, this oil phase is put into an aqueous phase in which a water-soluble polymer is dissolved, and emulsified and dispersed by a stirring means such as a homogenizer. The obtained emulsion is heated to cause a polymer formation reaction at the oil droplet interface. Thereby, a microcapsule in which a core material containing an aromatic component is coated with an outer shell material can be obtained.

  Note that as the outer shell material constituting the microcapsule, a material that is dissolved by heating or broken by thermal decomposition is used. As such a material, an organic material having a melting point of about 85 ° C. to about 135 ° C. is preferably used. In addition, melting | fusing point has the more preferable range of 85 to 105 degreeC. When the melting point is less than 85 ° C., when the fragrance sheet is left in a high temperature environment, the outer shell material of the microcapsule may spontaneously dissolve, and the fragrance component may volatilize outside. Further, when the melting point exceeds 135 ° C., even when heated by a heating element, the outer shell material of the microcapsule may not be dissolved, and the aromatic component may not be volatilized to the outside.

  Specific examples of the outer shell material include gelatin, rosin, gum arabic, shellac, sodium alginate, polyvinyl alcohol, epoxy, polyurethane, polystyrene, polyacrylamide, polyester, polyamide, urea and the like. Further, as a hydrophobic organic solvent that can be used together with an aromatic component as a core material, an organic solvent having a boiling point of 300 ° C. or less is preferable. For example, in addition to esters, dimethylnaphthalene, diethylnaphthalene, diisopropylnaphthalene, dimethylbiphenyl, diisopropyl Biphenyl, diisobutylbiphenyl, 1-methyl-1-dimethylphenyl-2-phenylmethane, 1-ethyl-1-dimethylphenyl-1-phenylmethane, 1-propyl-1-dimethylphenyl-1-phenylmethane, triallylmethane (Eg, tritoluylmethane, toluyldiphenylmethane), terphenyl compounds (eg, terphenyl), alkyl compounds, alkylated diphenyl ethers (eg, propyl diphenyl ether), hydrogenated terphenyls (eg, hexahi Rotafeniru), diphenyl ether and the like.

  Although it does not specifically limit as an average particle diameter of a microcapsule, The inside of the range of 10 micrometers-100 micrometers is preferable, and the inside of the range of 10 micrometers-30 micrometers is more preferable. When the average particle size is less than 20 μm, the content ratio of the fragrance component in the total mass of the microcapsules becomes too small, and it may be difficult to volatilize the fragrance component at a sufficient concentration. Further, when the average particle size exceeds 100 μm, the mechanical strength of the microcapsules may be lowered. For this reason, when a pressure is applied to the microcapsule by bending or pressing the fragrance sheet, the microcapsule is easily broken, and the fragrance component is easily volatilized outside at an unintended timing.

  In addition, the microcapsules can be arranged at any position on the surface or inside of the sheet-like substrate as long as they are arranged at least in the heating region. However, the surface of the sheet-like substrate is exposed to mechanical stimuli such as friction, and the microcapsules are easily broken. For this reason, it is preferable that a microcapsule is arrange | positioned inside a sheet-like base material. In this case, it is preferable that the sheet-like substrate has a hollow portion, and the microcapsules are disposed in the hollow portion. Moreover, you may arrange | position a microcapsule in the area | region away from the heating area | region as needed. For example, when the sheet-like substrate is composed of a fibrous material or a porous body, the microcapsules can be evenly dispersed and arranged in the sheet-like substrate. When the sheet-like substrate is composed of a fibrous substance, the microcapsules can be confined in a network structure formed by the fibrous substance.

-Sheet base material-
The sheet-like base material constituting the aromatic sheet has air permeability. Note that the “air permeability” is not limited to the case where gas can permeate from the front surface to the back surface, such as a paper sheet mainly composed of pulp fibers. This means that there is a path through which the fragrance component can diffuse and move from the region (for example, a hollow portion) in the substrate where the microcapsules are arranged to the fragrance sheet surface. Thereby, when the microcapsule is heated and destroyed by heating of the heating element, the fragrance component diffused out of the microcapsule can be volatilized outside without being confined in the fragrance sheet.

  As a material constituting the sheet-like base material, an air-permeable material having fine and continuous voids such as a fibrous material or a porous material can be used, but it does not have such a structure. Materials can also be used. However, when the sheet-like base material is made of a non-air-permeable material, a communication hole (aroma component diffuses and moves from the region where the microcapsules in the sheet-like base material are arranged to the surface of the sheet-like base material) It is necessary to have a possible route). Moreover, since the size of the communication hole is usually sufficiently larger than the void size of the fibrous material or the porous material, the diffusion rate of the fragrance component in the thickness direction of the sheet-like substrate can be increased. Therefore, regardless of whether or not the sheet-like base material is made of a non-air-permeable material, the fragrance component that volatilizes to the outside of the fragrance sheet within a short time after the microcapsule is heated by the heating element. Similarly, when it is desired to control the concentration of the sheet, it is preferable to provide a communication hole in the sheet-like substrate. Moreover, when a sheet-like base material is comprised by bonding two sheet-like materials, you may provide a clearance gap so that a communicating hole may be formed in a part of bonding interface.

  Although the diameter of a communicating hole is not specifically limited, The range of 5 micrometers-30 micrometers is preferable, and the range of 5 micrometers-9 micrometers is more preferable. If the diameter is less than 5 μm, it may be difficult to form a communication hole in the sheet-like substrate, or clogging may easily occur due to dust or dust. In addition, when the diameter exceeds 30 μm, the opening of the communication hole on the surface of the sheet-like substrate is likely to be noticeable, and the aesthetics may be deteriorated. The “diameter of the communication hole” means the maximum diameter of a circle having the same cross-sectional area as the cross-sectional shape when the cross-sectional shape of the communication hole is not circular.

  As a material constituting the sheet-like substrate, a known solid material can be used, and two or more kinds can be used in combination. Of these, it is particularly preferable to use at least one selected from resins, fibrous substances, and ceramics. Examples of the resin include polyimide and Teflon (registered trademark). Examples of the fibrous substance include pulp fiber, carbon fiber (carbon fiber), glass fiber and the like. Examples of ceramics include alumina and zirconia. Note that the materials themselves of the resin and ceramics are non-permeable. However, a porous resin or ceramic can be used as necessary.

  Moreover, when an easily deformable material such as a resin or a fibrous substance is used as the sheet-like base material, flexibility can be imparted to the aromatic sheet. In addition, even when ceramics that are susceptible to brittle fracture are used as the sheet-like substrate, the sheet-like substrate is made thin, or the aromatic sheet is made flexible by using ceramics with high bending strength. Can do. When the fragrance sheet has flexibility as described above, the fragrance sheet can be used even in applications where bending or stretching is required. Thereby, an aroma sheet can be affixed and used for the surface of the member with an unevenness | corrugation on the surface, for example.

  Although the thickness of a sheet-like base material is not specifically limited, It is preferable to exist in the range of 30 micrometers-300 micrometers, and it is more preferable that it exists in the range of 50 micrometers-100 micrometers. When the thickness is less than 30 μm, the fragrance sheet may be easily damaged due to insufficient tensile strength. On the other hand, if the thickness exceeds 300 μm, it may be difficult to impart flexibility to the fragrance sheet even if the fragrance sheet is produced using a sheet-like substrate made of a flexible material. For this reason, there are cases where the fragrance sheet cannot be applied to an electronic device whose casing surface has a curved surface or irregularities. The sheet-like base material may be composed of one sheet-like material, but may be composed of two or more sheet-like materials bonded together. In addition, when using 2 or more sheet-like material, the material and cross-sectional structure which comprise each sheet-like material may differ.

-Heating element-
The heating element provided in the fragrance sheet has a function of selectively heating a partial region of the plane of the sheet-like substrate. The heating element is electrically turned on / off as will be described later. For this reason, even if it does not apply pressing force to the fragrance sheet as disclosed in Patent Document 1, by electrically controlling the heating element at a desired timing, the microcapsules are destroyed by heating and the fragrance component is volatilized. be able to.

In addition, as a heating method of a microcapsule, the following two heating methods are mentioned.
(1) 1st heating system The heating system which heats a microcapsule (outer shell material) by supplying heat energy directly from the outside to the area | region where a microcapsule exists.
(2) Second heating method A heating method that heats the microcapsule (outer shell material) by vigorously vibrating the molecules constituting the outer shell material by generating a high frequency in the region where the microcapsule exists.

  In the first heating method, the heating element is configured using a heating wire that generates heat when a current is passed. In this case, when the heat energy supplied from one heating wire is an amount of energy sufficient to heat break the microcapsule, the heating element is constituted by one heating wire. In this case, the microcapsule is disposed at least in the vicinity (heating region) of the heating wire. In the case where the heating element is composed of one heating wire, the heating wire may be linear, but may be coiled. In this case, the microcapsules are arranged in the coil or in the vicinity thereof (heating region).

  In addition, even if the heat energy supplied from one heating wire is insufficient for heating and destroying the microcapsule, the two heating elements arranged so as to cross each other or be parallel to each other. If the total amount of heat energy supplied from the wires is sufficient for heating and destroying the microcapsules, the heating element is composed of these two heating wires. When two heating lines intersect with each other in the plane or inside of the sheet-like base material and are separated in the thickness direction of the sheet-like base material, a region where the two heating lines intersect The vicinity becomes a heating region.

  In addition, as a heat generating wire, a well-known heat generating wire can be used as long as it generates heat by passing an electric current, but a tungsten wire, a nichrome wire, a stainless steel wire, a piano wire, or the like can be used. The heating wire may be disposed on the surface of the sheet-like substrate, but from the viewpoint of ensuring aesthetics, it is preferably arranged so as to be embedded in the sheet-like substrate. The diameter of the heating wire is not particularly limited, but when the heating wire is embedded in the sheet-like substrate, it is preferably in the range of 12 μm to 200 μm, and more preferably in the range of 20 μm to 100 μm. If the diameter is less than 12 μm, a sufficient amount of heat generation may not be obtained, or disconnection may occur easily. If the diameter exceeds 200 μm, it may be difficult to embed the heating lines inside the sheet-like substrate, Heat generation control may be difficult. Note that the heat generation amount of the heating wire can be adjusted by appropriately selecting the distance between the heating wires when using the electrical resistance of the heating wire, the current amount, the diameter of the heating wire, and two heating wires.

  In the second heating method, the heating element is composed of two conductive wires arranged so as to intersect each other in the plane or inside of the sheet-like base material and to be separated from each other in the thickness direction of the sheet-like base material. The vicinity of the region where the conducting wires intersect is a region where the high frequency is generated (heating region). For this reason, the microcapsule can be destroyed by heating if a current is simultaneously supplied to the two conductive wires in a state where the microcapsule is disposed in this region. Although conducting wire may be arranged on the surface of a sheet-like base material, it is preferred to arrange so that it may be embedded inside a sheet-like base material from a viewpoint of securing aesthetics. The diameter of the conducting wire is not particularly limited, but when the conducting wire is embedded in the sheet-like base material, it is preferably in the range of 30 μm to 200 μm, and more preferably in the range of 50 μm to 100 μm. If the diameter is less than 30 μm, disconnection may easily occur, and if the diameter exceeds 200 μm, it may be difficult to embed the heating wire inside the sheet-like substrate.

  In addition, it is preferable to arrange | position so that the axial direction may be substantially parallel to the plane of a sheet-like base material. In other words, in the case where the heating element is the first heating method or the second heating method, one wiring (heating wire or conductive wire, hereinafter the same) whose axial direction is substantially parallel to the plane of the sheet-like base material, Another wiring that is spaced apart from one wiring with respect to the thickness direction of the base material, is substantially parallel to the plane of the sheet-like base material, and is arranged so as to intersect with the one wiring. It is preferable. In this case, a region where one wiring and another wiring intersect functions as a heating element. When a heating element is configured by combining two wirings, one wiring is arranged on one side of the sheet-like base material in the thickness direction, and the other wiring is on the other side of the thickness direction center. It is preferable to arrange on the side.

  As described above, the number of heating regions provided in the fragrance sheet may be at least one, but can usually be appropriately selected according to the type of electronic device and the form of use. Moreover, when the number of heating areas is four or more, it is preferable that each heating area | region is arrange | positioned at the plane or inside of a sheet-like base material at the matrix form. In this case, two or more heating wires (or conducting wires) are arranged in the row direction, and two or more heating wires (or conducting wires) are arranged so as to intersect the heating wires (or conducting wires) arranged in the row direction. By arrange | positioning in a row direction, a heating area | region can be provided in a matrix form in the plane or inside of a sheet-like base material. When such a configuration is adopted, it is specified by selecting a specific row direction and column direction heating wire (or conducting wire) from the heat generating wires (or conducting wires) in the row direction and the column direction, and supplying current. Only the heating region can be heated.

  A built-in power source (battery or the like) built in the electronic device can be used to supply current to the heating wire (or conducting wire) constituting the heating element. When the electronic device does not have a built-in power source and uses an external power source such as an outlet, the external power source can be used via the electronic device. In addition, heating / non-heating control of the heating region may be performed manually, but it is usually preferable to use a control circuit such as an IC chip. In particular, when the heating area is provided in a matrix with respect to the planar direction of the fragrance sheet, it is preferable to perform heating / non-heating control of the heating area using the control means. The control circuit is usually preferably provided outside the fragrance sheet, but may be provided on the fragrance sheet side if necessary.

-Volatilization of aromatic components-
In order to volatilize the fragrance component to the outside of the fragrance sheet using the fragrance sheet, heating may be performed in at least one heating region (selected from one or more heating regions) provided in the fragrance sheet. . Thereby, the microcapsule which exists in the heating area | region which heated was destroyed by heating, and an aroma component can be volatilized to the exterior of an aroma sheet.

  In addition, when the fragrance sheet has two or more heating regions, the heating is not performed once after performing the first heat treatment for selecting and heating a part of all the heating regions. It is particularly preferable to repeat the heat treatment in which heating is performed by selecting a part or all of the remaining heating region one or more times. In this case, it is possible to volatilize the fragrance component to the outside of the fragrance sheet in two or more times over time. For this reason, an aromatic component can be volatilized any number of times at a desired timing by selecting a heating region for heating the microcapsules and controlling the heating timing.

-Specific examples of fragrance sheets-
Next, specific examples of the fragrance sheet will be described with reference to the drawings. FIG. 1 is a schematic cross-sectional view illustrating an example of an aroma sheet used in the electronic apparatus of the present embodiment. A fragrance sheet 10 shown in FIG. 1 includes a sheet-like base material 20A, a hollow portion 22 provided in the vicinity of the central portion in the thickness direction of the sheet-like base material 20A, and a plurality of microcapsules filled in the hollow portion 22 ( A heating wire (heating) arranged in a region between the surface on one side of the sheet-like substrate 20A and the hollow portion 22 so that the axial direction is parallel to the plane of the sheet-like substrate 20A. A part of the element), and in the region between the surface of the other side of the sheet-like base material 20A and the hollow portion 22, the axial direction is parallel to the plane of the sheet-like base material 20A, and And a heating wire (constituting a part of the heating element) 32 arranged so as to be orthogonal to the axial direction of the heating wire 30.

  FIG. 2 is a schematic diagram showing the arrangement of the heating wire 30, the heating wire 32, and the hollow portion 22 when the fragrance sheet 10 shown in FIG. 1 is viewed from one side. As shown in FIG. 2, the heating lines 30A, 30B, 30C, and 30D are arranged so as to be parallel to the column direction and at equal intervals, and the heating lines 32A, 32B, 32C, and 32D are parallel to the row direction. The heating lines 30A, 30B, 30C, and 30D and the heating lines 32A, 32B, 32C, and 32D are orthogonal to each other. And the hollow part 22 is arrange | positioned in the area | region where heating wire 30A, 30B, 30C, 30D and heating wire 32A, 32B, 32C, 32D cross | intersect. The heating lines 30 and 32 are connected to a power source and a control circuit (not shown), and the ON / OFF state is controlled for each heating line.

  20 A of sheet-like base materials have air permeability, since it is comprised considering the material (porous material or fibrous substance) which has air permeability as a main material. For this reason, when the microcapsule disposed in the hollow portion 22 is destroyed by heating, the fragrance component contained in the microcapsule diffuses and moves from the hollow portion 22 to the surface of the sheet-like base material 20A. Can be stripped. In addition, when the material which comprises a sheet-like base material does not have air permeability, the communicating hole connected from the hollow part 22 to the surface of the sheet-like base material 20A is provided. In the fragrance sheet 10, portions where the heating lines 30 </ b> A, 30 </ b> B, 30 </ b> C, 30 </ b> D and the heating line 32 intersect (areas 22 </ b> A, 22 </ b> B, 22 </ b> C, 22 </ b> D indicated by dotted lines) function as heating areas. For this reason, a heating area | region will be provided in the vicinity of each hollow part 40A, 40B, 40C, 40D, respectively. However, in the embodiment shown in FIG. 1 and FIG. 2, when a current is passed through only the heating wire 30 or only the heating wire 32 in order to destroy the microcapsules arranged in the hollow portion 22 by heating, The heat generation amount of the heating wires 30 and 32 is controlled so that the capsule cannot be broken by heating.

  Next, an example of the procedure for volatilizing a fragrance component using the fragrance sheet 10 shown in FIGS. 1 and 2 will be described. First, from the heating lines 30 arranged in the column direction and the heating lines 32 arranged in the row direction, the heating lines through which current flows are respectively selected, and current is simultaneously supplied. For example, a current can be simultaneously supplied to the heating wire 30A and the heating wire 32A. Thereby, the microcapsule filled in the hollow portion 22 existing in the region where the heating wire 30A and the heating wire 32A intersect is heated and destroyed. At this time, the fragrance component encapsulated in the microcapsule passes through the sheet-like substrate 20A and is volatilized to the outside. In this case, only the microcapsules existing in one hollow portion 22 are heated, but the microcapsules present in two or more hollow portions 22 may be simultaneously heat-treated. For example, a current can be simultaneously supplied to the heating wire 30A, the heating wire 32A, and the heating wire 32B.

  In addition, the hollow part 22 once heat-processed lose | disappears or reduces significantly the function to volatilize an aroma component. For this reason, when selecting the heating line which flows an electric current next from the heating line 30 arranged in the column direction and the heating line 32 arranged in the row direction, the hollow part 22 which is not heat-treated can be heated. It is particularly preferable to select the heating line. By repeating the process as described above, as long as there is a hollow portion 22 that is not heat-treated in the fragrance sheet 10, the fragrance component can be volatilized any number of times at a desired timing. In addition, the volatilization amount and volatilization rate of the fragrance component are the number of hollow portions 22 to be heat-treated at the same time, the amount of current flowing through the heating wire 30A and the heating wire 32A, the energization time, the thickness of the sheet-like substrate 20A, the sheet shape. When the base 20A is made of a gas-permeable material such as a porous material or a fibrous material, the porosity of these materials, and when the sheet-like base 20A is made of a non-air-permeable material, the diameter of the communication hole. It can be controlled by adjusting.

  The fragrance sheet 10 shown in FIG. 1 and FIG. 2 is provided with heating lines 30 and 32, but instead of these heating lines 30 and 32, conductive wires may be used. In this case, by generating a high frequency in a region where the conducting wire 30 and the conducting wire 32 intersect, the microcapsules filled in the hollow portion 22 existing in the region can be destroyed by heating. Moreover, in the fragrance sheet 10 shown in FIGS. 1 and 2, the microcapsules are disposed in the hollow portion 22. However, the microcapsules can be arranged in other ways. For example, when the sheet-like base material 20A is composed of a fibrous substance or a porous material and does not have the hollow portion 22, for example, the microcapsules are dispersed and arranged over the entire sheet-like base material 20A. May be. However, when it is desired to increase the utilization efficiency of the microcapsules, it is preferable to disperse and arrange the microcapsules in a part or all of the regions 40 indicated by the dotted lines in FIG. In addition, as a method of dispersing the microcapsules in the sheet-like base material 20A, for example, using a solution in which microcapsules are dispersed, the sheet-like base material 20A is immersed in the solution, or the sheet-like base material 20A is used. The method of dripping a solution to the specific area | region of the surface of 20 A of base materials is mentioned.

  Next, a specific example of the fragrance sheet in which the communication holes are provided in the sheet-like substrate will be described with reference to the drawings. FIG. 3 is a schematic diagram illustrating another example of an aroma sheet. In addition, in FIG. 3, description is abbreviate | omitted about the heating wire (or conducting wire) which comprises a heating element. 3 includes a sheet-like base material 20B, a hollow portion 22 provided in the center of the sheet-like base material 20B in the thickness direction, and the sheet-like base material 20B from the hollow portion 22. A communication hole 24 provided so as to communicate with the surface on one side, a microcapsule (not shown) disposed in the hollow portion 22, and a heating element including a heating wire (or conducting wire) (not shown) , Is composed of. Note that the heating element can be provided in a manner similar to that shown in FIGS.

  In the fragrance sheet 12 shown in FIG. 3, when the microcapsules in the hollow portion 22 are broken by heating by the heating element, the fragrance component contained in the microcapsules passes through the communication holes 24 and is external to the fragrance sheet 12. Can be volatilized quickly. In addition, in the fragrance sheet 12 shown in FIG. 3, the communication hole 24 is provided so that the opening part is located only in the single side | surface of the sheet-like base material 20B. By adopting such a configuration, when the fragrance sheet 12 is used by being attached to the surface of some member, the use of the microcapsule is provided by providing an opening on the surface opposite to the surface to be attached. Efficiency can be increased. However, the communication holes 24 may be provided so that the openings are located on both surfaces of the sheet-like substrate 20B.

-Manufacturing method of fragrance sheet-
The fragrance sheet can be produced by appropriately using a known method for producing a sheet-like member depending on the configuration of the fragrance sheet. An aromatic sheet can be produced, for example, according to the following procedure. However, the manufacturing method of an aromatic sheet is not limited to this.

(1) Preparation of microcapsules Microcapsules containing a desired fragrance component are prepared by the method described above.

(2) Preparation of sheet containing heating wire (or conducting wire) A plurality of heating wires (or conducting wires) are arranged in parallel and at equal intervals on one side of the sheet-like material. Next, another sheet-like material is pasted together so as to cover the surface on which the heating wire (or conducting wire) of the sheet-like material is arranged, thereby preparing a sheet containing heating wire (or conducting wire).

(3) Arrangement of microcapsules Microcapsules are arranged at equal intervals along a line provided with heating wires (or conducting wires) on one side of a sheet containing heating wires (or conducting wires). In arranging the microcapsules, for example, a method of injecting microcapsules (or a solution or gel in which the microcapsules are dispersed) into a predetermined position on the sheet using a dispenser can be used.

(4) Lamination of sheet containing heating wire (or conducting wire) Subsequently, another sheet containing heating wire (or conducting wire) is placed on the surface of the sheet containing heating wire (or conducting wire) on which microcapsules are arranged. to paste together. In this case, when the two sheets are bonded, the heating wire (or conducting wire) of one sheet and the heating wire (or conducting wire) of the other sheet are orthogonal to each other, and the orthogonal region and the microcapsule are arranged. This is performed so that the region matches. Thereby, an aroma sheet can be obtained. In addition, if the recessed part is previously provided in the position where the microcapsule of a sheet | seat containing a heating wire (or conducting wire) is arrange | positioned, the said recessed part will comprise the hollow part of an aromatic sheet (in this case, FIG. A fragrance sheet having the configuration shown in FIG. 2 can be obtained). In addition, in order to adjust the thickness of an aroma sheet or to smooth an unevenness | corrugation, you may press-process using a roll etc. after bonding.

  In addition, the fragrance sheet produced through the above-described process is attached to an electronic device. In this case, it may be directly attached and fixed to the surface of the housing of the electronic device, or may be fixed to the surface of a panel that can be attached to and detached from the surface of the housing, as in the case of so-called changeable mobile phones. Further, when the fragrance sheet is manufactured, the fragrance sheet may be used as a member constituting the surface of the casing by being manufactured so as to be integrated with the casing. Further, the heating wire (or conducting wire) of the fragrance sheet is electrically connected to the power source (or control circuit) of the electronic device body.

-Specific examples of electronic devices-
Next, a specific example of the electronic apparatus according to the first embodiment will be described with reference to the drawings. FIG. 4 is a schematic diagram showing an example of the configuration of the electronic apparatus according to the first embodiment. The electronic device 100 illustrated in FIG. 4 includes a control unit 102, an input unit 104, a detection unit 106, a fragrance unit 108, a broadcast reception unit 110, a communication unit 112, a memory unit 114, and a display unit 116. The control unit 102 is connected to the input unit 104, the detection unit 106, the fragrance unit 108, the broadcast reception unit 110, the communication unit 112, the memory unit 114, and the display unit 116. The control unit 102 is mainly configured by a CPU.

  Next, an example of a process for controlling the aroma function of an electronic device will be described with reference to a flowchart. FIG. 5 is a flowchart showing an example of the control process of the electronic device according to the first embodiment. Specifically, the electronic device is switched from the OFF state (completely stopped state) to the standby state. It is a flowchart shown about an example of control of an aroma function. In FIG. 5, ST1 is a step representing a complete stop state, ST2 is a step for determining whether or not the power is on, ST3 is a step for performing an aroma function, and ST4 is a step for determining whether or not a certain time has elapsed. ST5 is a step representing a state (standby state) in which any function of the electronic device is not exhibited while the power is on after a certain time has elapsed.

  The process shown in FIG. 5 proceeds as follows. First, in ST2, it is determined whether or not the power is turned on by pressing the power button or the like. If the power is OFF, the process returns to ST1 (completely stopped state). Further, when it is determined that the power supply is turned on, the aroma function is exhibited from the time when the power is turned on in ST3. Thereafter, the process proceeds to ST4 and it is determined whether or not a certain time has elapsed. In ST4, until a predetermined time elapses, the state where the fragrance function is not exhibited is maintained regardless of any button operation. Thereafter, when ST4 ends, the process proceeds to ST5 and enters a standby state. In addition, the length of the fixed time in ST4 can be set as appropriate according to the type of electronic device and its usage. For example, when the electronic device is a mobile phone, the user often performs some kind of operation after the power is turned on. Therefore, a certain length of time is set so that the process proceeds to ST5 after such a period has elapsed. Can be set.

Specifically, the electronic device transitions from a standby state to a state where a specific function is exhibited. It is a flowchart shown about an example of control of an aroma function. In FIG. 6, ST1 is a step representing a standby state, ST2 is a step of determining whether or not a specific function (other than the fragrance function) (hereinafter sometimes simply referred to as “specific function”) has been selected and exhibited. ST3 is a step for determining whether or not the specific function selected / executed is a function linked to the display of the fragrance function, ST4 is a step for demonstrating the fragrance function, and ST5 is for determining whether or not a certain time has elapsed. Step ST6 is a step of determining whether or not the specific function has been performed.

  The process shown in FIG. 6 proceeds as follows. First, in ST2, it is determined whether or not a specific function is selected / executed. When the specific function is not selected / executed, the process returns to ST1 and the standby state is maintained. On the other hand, if the specific function is selected / executed, the process proceeds to ST3. In ST3, it is determined whether or not the specific function selected and exhibited is a function that is exhibited in conjunction with the aroma function. For example, in a cellular phone, when the character input function (phone number input function) is demonstrated to demonstrate the call function, or only when the character input function (document creation function) is demonstrated for e-mail transmission If the specific function is selected when the fragrance function is set to work together, the process proceeds sequentially to ST4, ST5, ST6. On the other hand, when the digital terrestrial television broadcast display function or the music playback function is selected, these specific functions are not set so that the fragrance function is exhibited in conjunction with each other, so ST4 and ST5 are skipped and the process goes to ST6. Will proceed.

  In ST3, when it is determined that the specific function selected and exhibited is a function that is exhibited in conjunction with the aroma function, the process proceeds to ST4, where the aroma function is exhibited. Thereafter, the process proceeds to ST5 and it is determined whether or not a certain time has elapsed. In ST5, until a certain time elapses, the state where the fragrance function is not exhibited is maintained regardless of any button operation. Thereafter, when ST5 ends, the process proceeds to ST6, in which it is determined whether or not the specific function has been performed. When the specific function is maintained, the process returns to ST6. On the other hand, when the performance state of the specific function ends, the process returns to ST1 and enters a standby state. In addition, the length of the fixed time in ST5 can be set as appropriate according to the type of electronic device and its usage.

  FIG. 7 is a flowchart showing another example of the control process of the electronic device according to the first embodiment. Specifically, the electronic device can be manually opened and closed by a mobile phone or the like. It is a flowchart shown about an example of control of the fragrance function interlock | cooperated with the deformation | transformation operation | movement in the electronic device which can be reversibly deform | transformed into three types of different shapes, one open shape and a 2nd open shape. In FIG. 7, ST1 is a step representing the power ON state, ST2 is a step of determining whether or not the first open shape has been transformed, ST3 is a step of performing the first fragrance function, and ST4 is A step of determining whether or not the deformation into the second open shape has been performed, ST5 is a step of performing the second fragrance function, and ST6 is a step of representing a standby state.

  The process shown in FIG. 7 proceeds as follows. First, in ST1, the power of the electronic device is turned on, and then the process proceeds to ST2. In ST2, it is determined whether or not a deformation operation to the first open shape has been performed. If the deformation operation to the first open shape has not been performed, the process returns to ST2, and if the deformation operation to the first open shape has been performed, the process proceeds to ST3. In ST3, the first aroma function is exhibited (in conjunction with the deformation operation to the first open shape). Subsequently, the process proceeds to ST4, and it is determined whether or not the deformation operation to the second open shape has been performed. If the deformation operation to the second open shape has not been performed, the process returns to ST4, and if the deformation operation to the second open shape has been performed, the process proceeds to ST5. In ST5, the second fragrance function is exhibited (in conjunction with the deformation operation to the second open shape). When ST5 ends, the process proceeds to ST6, and the electronic device enters a standby state.

  The first fragrance function in ST3 and the second fragrance function in ST5 may be exactly the same in the type of fragrance component, fragrance intensity, fragrance time, etc., but are preferably different from each other. . In addition, when an electronic device is capable of selecting and exhibiting two or more types of specific functions, the first open shape enables the display of one specific function, and the second open shape. Thus, the other specific functions different from the one specific function may be linked to each other. For example, if the electronic device is a mobile phone with a digital TV viewing function, the first open shape allows other functions other than the calling function and the digital TV viewing function to be performed. With the open shape, the viewing function of the digital television can be exhibited.

  Hereinafter, examples of the electronic apparatus of the present invention will be described. In the description of the following examples, only the portion of the fragrance sheet was produced and evaluated for the purpose of confirming the operation of the fragrance sheet used in the electronic device.

(Production of fragrance-containing microcapsules)
An emulsion containing a blend of self-emulsifying wax, non-self-emulsifying wax, and perfume mixture dispersed in a polyvinyl alcohol solution was prepared by the following steps. 20 g self-emulsifying Duroxon J-324 wax (melting point 105-115 ° C., Durachem), 20 g non-self-emulsifying Unilin 700 wax (melting point 110 ° C., Petrolite), 0.50 g potassium hydroxide, and 20 g deionized Water was placed in a 500 ml reactor equipped with a stirrer, temperature controller, and cooler.
Subsequently, the reactor was heated and held at 100 ° C. until the wax melted to produce a smooth homogeneous solution. 16 g of boiling deionized water was slowly added to the molten water mixture and kept at 100 ° C. until a clear colorless solution was observed. After this, 44 g of fragrance (Musk C-14, manufactured by Takasago Fragrance Co., Ltd .; musk fragrance) was gradually added to the wax mixture at 100 ° C. to produce a honey-like viscous solution. Next, 80 g of boiling deionized water was added to the reactor to produce a milky wax / perfume mixture emulsion. To this emulsion, 136 g of polyvinyl alcohol solution (weight average molecular weight 2,000, 17.6% solids) is added, and the emulsion is cooled to 40-50 ° C. in a water bath to produce a stable emulsion. did. The resulting emulsion was spray dried at 120 ° C. inlet air temperature using a Yamato GA31 mini spray dryer to produce microcapsules containing 40% fragrance.

(Preparation of sheet with heating wire)
Commercially available PPC paper (manufactured by Fuji Xerox Co., Ltd., ^{C 2} paper) was cut vertically and horizontally 25 mm × 25 mm on, after placing in 2mm intervals in a straight line the nichrome wire having a diameter of 0.2 mm, another piece of PPC thereon The paper was pasted together. As a result, two paper substrates containing nichrome wire were obtained.

(Production of fragrance sheet)
Subsequently, 0.2 cc of an alcohol solution in which microcapsules having a concentration of 10% were dispersed every 2 mm along the nichrome wire was dropped on one side of the sheet containing the nichrome wire. Then, another fragrance sheet was bonded to the surface on which the microcapsule solution was dropped so that the nichrome wires were orthogonal to each other to obtain an aroma sheet. In addition, at the time of bonding, it adjusted so that the point which the nichrome wire of the paper base material of front and back cross | intersects, and the point which dripped the microcapsule solution may correspond. The aromatic substrate thus obtained had 12 nichrome wires in the vertical and horizontal directions (row direction and column direction), and the points (number of heating regions) where the nichrome wires intersected each other were 12 × 12. In addition, since this fragrance sheet has a size of 25 mm × 25 mm in length and flexibility, it can be easily applied to a portable electronic device such as a cellular phone whose surface is curved or uneven. Could be attached to.

(Aroma evaluation)
Next, a direct current power source (voltage 1...) Is controlled so that each nichrome wire arranged in the row direction of the aromatic substrate and each nichrome wire arranged in the column direction can be controlled on and off in units of each nichrome wire. A 5V dry battery and a voltage applied to each nichrome wire were connected to 1.5V). In the following description, when referring to individual nichrome wires in the row direction and the column direction, numbers 1 to 12 are assigned for distinction.

-Environmental test-
Next, with the continuity to all nichrome wires turned off, the fragrance substrate was left in a high-temperature and high-humidity environment (temperature 50 degrees, humidity 90%), and the presence or absence of fragrance at this time was confirmed. No fragrance could be confirmed. From this, it was confirmed that the microcapsules in the fragrance substrate were not thermally destroyed under a general high temperature environment.

-Aroma test-
Next, when a current was passed through the first and second nichrome wires in the row direction and the first and second nichrome wires in the column direction for 3 seconds, the scent of musk was confirmed. When the scent of musk ceased, current was passed through the third and fourth nichrome wires in the row direction and the first and second nichrome wires in the column direction for 3 seconds. The scent of musk was as strong as the fragrance test. From the above, it was confirmed that the microcapsules existing in the vicinity of the point where the nichrome wires intersect vertically and horizontally were thermally destroyed, and the aromatic component in the microcapsules was volatilized.

-Long-term neglect test-
Subsequently, the fragrance sheet after the fragrance test was left in a room temperature and humidity environment (temperature 23 ° C., humidity 60%) for about one month. After that, when a current was passed through the fifth and sixth nichrome wires in the row direction and the first and second nichrome wires in the column direction for 3 seconds, the same level of musk as in the first and second fragrance tests. The scent of was confirmed. From the above, it was confirmed that the fragrance function of the fragrance substrate does not deteriorate even when the fragrance sheet is not used for a long time.
