The correspondence table 12a is a table showing the correspondence between the shape of the tip of the medicine cartridge 21 and the name of the medicine cartridge 21, for example, as shown in FIG. However, although the shape of the tip of the medicine cartridge 21 is displayed as an image in FIG. 6, the number, width, interval, depth, and the like of the notch portions are actually recorded as numerical data.

The setting information 27 is composed of three items A to C. The item A is the type of medicine to be released for each situation, and the item B is the time to start energizing the heater 13 prior to the start time of the schedule. Item C indicates the attribute of the face that is energized by the heater 13 when a face is detected. Item A is subdivided into A1 to A3 according to the energization situation. A1 is referenced when the pressure-sensitive switch is pressed, A2 is referenced when a predetermined time has passed before the start time of the schedule, and A3 is referenced when a face that meets a predetermined condition is detected. The
FIG. 7 shows an example of the setting information 27. Item A1 releases the vanilla scent when the pressure-sensitive switch is pressed, item A2 releases the deodorant component a predetermined time before the schedule start time, and item A3 meets the predetermined condition. It is shown that the scent of lavender is released when the face to be detected is detected. The item B indicates that the heater 13 is energized 10 minutes before the start time of the schedule, and the item C indicates that a woman over 20 years old is the target attribute.

The facial feature quantity database 28 stores samples of facial feature quantities classified for each sex and age group, created from a large number of face images with clear gender and age group. Therefore, when there is a face image whose gender and age group are unknown, the feature amount is calculated from the face image, and compared with the feature amount sample stored in the face feature amount database 28. Age group can be estimated.
In the timer time table 29, schedule start times received from the mobile terminal 30 are listed.

The heater 13 is energized from a battery (not shown) by the control unit 11 and becomes high temperature.

FIG. 8 is a flowchart showing the operation of the program executed by the control unit 11 of the wristwatch 10. The control unit 11 executes the program whose operation is shown in FIG. 8 at regular intervals, for example, every minute.

In step S <b> 101, the control unit 11 determines whether a signal indicating that the pressure sensitive switch 15 has been pressed is received from the pressure sensitive switch 15. If it is determined that a signal indicating that the pressure sensitive switch 15 has been pressed has been received, that is, if it is determined that the user has worn the wristwatch 10, the process proceeds to step S102. If it is determined that the signal indicating that the pressure-sensitive switch 15 has been pressed has not been received, that is, if it is determined that the user is not wearing the watch 10 or is wearing the watch 10 continuously, a step is performed. The process proceeds to S103.
In step S102, the control unit 11 reads the name of the medicine of item A1 from the setting information 27 stored in the storage unit 12. The control unit 11 issues a command to all the cartridge detection units 20 of the wristwatch 10 to transmit the shape of the tip of the medicine cartridge 21, and refers to the correspondence table 12 a stored in the ROM of the control unit 11, and item A 1 The insertion position of the medicine cartridge 21 containing the medicine described in 1. is specified. And it supplies with electricity to the heater 13 installed under it, and progresses to step S103. As described above, this energization is continued for a certain period of time, and the fan motor 14 operates in conjunction with the heater 13 for a certain period of time.

In step S <b> 103, the control unit 11 determines whether a push operation signal is received from any of the cartridge detection units 20. If it is determined that a push-in operation signal has been received from any cartridge detection unit 20, the process proceeds to step S104. If it is determined that no push-in operation signal has been received from any cartridge detection unit 20, the process proceeds to step S105.
In step S104, the control unit 11 energizes the heater 13 having the same number as the cartridge detection unit 20 that has transmitted the push-in operation signal, and proceeds to step S105. As described above, this energization is continued for a certain period of time, and the fan motor 14 operates in conjunction with the heater 13 for a certain period of time.

  In step S <b> 105, the control unit 11 communicates with the mobile terminal 30 through the communication unit 17 and acquires the start time of the schedule stored in the storage unit 32 of the mobile terminal 30. Then, the time is recorded in the timer time table 29 of the storage unit 12. However, in order to prevent the time from being recorded in the timer time table 29 in duplicate, even if the start time of the schedule already recorded is acquired, it is not recorded in the timer time table 29. Next, the process proceeds to step S106.

  In step S106, the control unit 11 refers to the setting information 27 and the timer timetable 29, and determines whether or not the current time is within a predetermined time from the start time of the schedule. That is, the time of the item B is read from the setting information 27, and the current time is before any time recorded in the timer time table 29, and after the time that is back by the time of the item B from that time. Determine whether or not. For example, when “time 14:15 on April 1, 2014” is stored in the timer time table 29 and the time of the item B of the setting information 27 is 10 minutes, the current time is April 1, 2014 If it is between 5 minutes and 14:15 on the same day, it is determined that the predetermined time condition is satisfied, and if the current time is other than that, it is determined that the predetermined time condition is not satisfied. If it is determined that the current time satisfies the predetermined time condition, the process proceeds to step S107. If it is determined that the current time does not satisfy the predetermined time condition, the process proceeds to step S108.

In step S107, the control unit 11 reads the name of the medicine of item A2 from the setting information 27 stored in the storage unit 12. The control unit 11 issues a command to all the cartridge detection units 20 of the wristwatch 10 to transmit the shape of the tip of the medicine cartridge 21, and refers to the correspondence table 12a stored in the ROM of the control unit 11 and item A2 The insertion position of the medicine cartridge 21 containing the medicine described in 1. is specified. And it supplies with electricity to the heater 13 installed under it, and progresses to step S108. As described above, this energization is continued for a certain period of time, and the fan motor 14 operates in conjunction with the heater 13 for a certain period of time.
In step S108, the control unit 11 images the subject by the imaging unit 16, detects a human face from the image obtained by imaging, and proceeds to step S109. For example, human face detection has a substantially circular outline, a nose having a vertical outline in the center, and a substantially circular eye in a symmetrical position at the top of the nose. It is detected from features such as a point with a lip having a horizontally long outline below. Next, the process proceeds to step S109.

In step S109, the control unit 11 determines whether or not the face detected in step S108 occupies a certain area ratio of the photographed image, for example, 20% or more. When it is determined that the detected face occupies a predetermined ratio or more, the process proceeds to step S110, and when it is determined that the detected face does not occupy the predetermined ratio or no face is detected, the flowchart of FIG. When the person to be photographed is near the wristwatch 10, the person to be photographed is greatly photographed in the image obtained by the photographing unit 16, so whether the person to be photographed is near the wristwatch 10 in this step S109. Judgment is simply made.
In step S110, the control unit 11 calculates the feature quantity of the face detected in step S108 and compares it with the feature quantity sample stored in the face feature quantity database 28, thereby obtaining the attribute of the subject, ie, the subject. The sex and age group of the photographer are estimated, and the process proceeds to step S111.

In step S111, the control unit 11 determines whether the attribute estimated in step S110 satisfies the condition of the target attribute of item C from the setting information 27 stored in the storage unit 12. For example, when the item C of the setting information 27 is “20 years or older, female” and the estimation result in step S110 is “30s, female”, it is determined that the condition of the item C is satisfied. If it is determined that the condition of the target attribute is satisfied, the process proceeds to step S112. If it is determined that the condition of the target attribute is not satisfied, the flowchart of FIG.
In step S112, the control unit 11 reads the name of the medicine of item A3 from the setting information 27 stored in the storage unit 12. The control unit 11 issues a command to all the cartridge detection units 20 of the wristwatch 10 to transmit the shape of the tip of the medicine cartridge 21, and refers to the correspondence table 12 a stored in the ROM of the control unit 11, and item A 3 The insertion position of the medicine cartridge 21 containing the medicine described in 1. is specified. Then, the heater 13 installed thereunder is energized, and the flowchart of FIG. 8 ends.

However, since the feature amount of the face has a large amount of information, it is stored separately in the storage unit 12 and only the number is recorded as the “feature amount number” in the preference aroma list 40. “Scent” represents the name of the medicine cartridge 21, “Heating amount” represents the heating amount of the heater 13, and “Air volume” represents the air volume of the fan motor 14.
The odor detection unit 41 has a sensor whose resistance value changes according to the intensity of the odor, measures the resistance value according to a command from the control unit 11, and sets a numerical value corresponding to the odor intensity to the control unit. 11 is output. For example, the sensor is a metal oxide, and outputs odorless “0” and maximum “10” to the control unit 11 according to the strength of the odor.
The setting information 27 includes, in addition to the configuration in the first embodiment, the type of medicine that is released when an odor is detected as A4. FIG. 11 shows an example of the setting information 27 in the second embodiment, and it can be seen from the description of A4 that a deodorant component is released when an odor is detected.

(Operation)
The operation of the wristwatch 10 in the second embodiment will be described. The wristwatch 10 according to the second embodiment performs the following operation in addition to the operation according to the first embodiment.
The control unit 11 causes the odor detection unit 41 to detect odors at regular intervals, and if the detected odor is not less than a predetermined intensity, for example, if the odor intensity is “4” or more, it is stored in the storage unit 12. The name of the medicine of item A4 is read from the setting information 27 being stored. The control unit 11 issues a command to all the cartridge detection units 20 of the wristwatch 10 to transmit the shape of the tip of the medicine cartridge 21, and refers to the correspondence table 12a stored in the ROM of the control unit 11 and item A4 The insertion position of the medicine cartridge 21 containing the medicine described in 1. is specified. And it supplies with electricity to the heater 13 installed under it. As described above, this energization is continued for a certain period of time, and the fan motor 14 operates in conjunction with the heater 13 for a certain period of time.

  Further, part of the program executed by the control unit 11 of the wristwatch 10 at regular intervals, step S112 in FIG. 8, is changed as follows. That is, in step S112, the control unit 11 searches for a feature amount described in the preference aroma list 40 that matches the feature amount of the face calculated in step S110. If there is a matching feature amount, the medicine cartridge 21 described in the matching feature amount column described in the preference fragrance list 40 is heated with the heating amount / air amount described in the matching feature amount column. Thus, the heater 13 is instructed to end the flowchart of FIG. When there is no matching feature amount, the name of the medicine of the item A3 is read from the setting information 27 stored in the storage unit 12, as in the first embodiment. The control unit 11 issues a command to all the cartridge detection units 20 of the wristwatch 10 to transmit the shape of the tip of the medicine cartridge 21, and refers to the correspondence table 12 a stored in the ROM of the control unit 11, and item A 3 The insertion position of the medicine cartridge 21 containing the medicine described in 1. is specified. Then, the heater 13 installed thereunder is energized, and the flowchart of FIG. 8 ends. As described above, this energization is continued for a certain period of time, and the fan motor 14 operates in conjunction with the heater 13 for a certain period of time.

In the second embodiment, the wristwatch 10 performs the following operation in addition to the first embodiment.
The wristwatch 10 further includes a preference fragrance list 40 and an odor detection unit 41 that store the facial feature amount, fragrance, heating amount, and air volume in association with each other. When the feature amount of the face detected from the image obtained by photographing by the photographing unit 16 is calculated and the feature amount is stored in the preference fragrance list 40, the medicine cartridge 21 having a scent associated with the feature amount. Is heated under the condition associated with the feature amount. Further, when the odor is detected by the odor detection unit 41 at regular time intervals and an odor of a predetermined intensity or higher is detected, the predetermined medicine cartridge 21 is heated with reference to the setting information 27 to reduce the odor.

According to the embodiment described above, the following operational effects can be obtained.
The wristwatch 10 includes a cartridge insertion part 22 for storing a replaceable medicine cartridge 21, an odor detection part 41 for detecting an odor at predetermined time intervals, and a medicine in the medicine cartridge 21 inserted in the cartridge insertion part 22. That is, the heater 13 that heats the fragrance or the deodorant agent, and the control unit 11 that starts the heating when the odor detecting unit 41 detects an odor of a predetermined strength or more are provided.
Therefore, the discomfort of the user of the wristwatch 10 and surrounding people due to odor can be reduced.
