Accordingly, when the zoom function of the camera 53 is controlled in conjunction with the operation of the small electric devices 1 and 2 by the user, the user can smoothly change the zoom magnification of the camera 53.

  In the case of using the small electric devices 1 and 2 such as the electric shaver and the beauty tool in the usual method, a moving operation such as moving the small electric devices 1 and 2 along the face skin is involved. Therefore, if the zoom function of the camera 53 is controlled in conjunction with the movement operation of the small electric devices 1 and 2, the zoom magnification is automatically set without the user performing a specific operation for zoom control. As it is changed, it is possible to save the trouble of the zoom operation by the user.

  The treatment of the face skin with small electric devices 1 and 2 such as electric razors and beauty tools is not uniformly applied to the whole face, but rather carefully processed with the relatively roughly processed parts There is a site to be Therefore, depending on the part of the user's face directly facing the functional parts 12 and 32 of the small electric devices 1, 2, that is, the part of the face to be processed by the user with the functional parts 12 and 32. When controlled, the zoom magnification of the camera 53 can be automatically changed to a value suitable for the region concerned, and the convenience for the user is further improved.

  When the zoom function of the camera 53 is controlled in conjunction with the moving operation of the display device 5, the user can change the zoom magnification of the camera 53 by a simple operation of moving the display device 5. When using the small electric devices 1 and 2 and the display device 5 instead of the hand mirror at the same time, the display device 5 is often held with the hand opposite to the dominant hand, but if only moving the display device 5 The zoom operation can be easily performed even with the hand opposite to the dominant hand.

  If the zoom function of the camera 53 is controlled in accordance with the expression of the face area recognized by the face recognition function, the user can change the zoom magnification of the camera 53 simply by changing the expression appearing on the camera 53. Therefore, the user's convenience can be improved by omitting the operation of the small-sized electrical apparatus 1 or 2 or the display device 5 for changing the zoom factor.

  If an auxiliary illustration 70 such as an unprocessed illustration 71 or a processed illustration 72 is added to the face area shown on the display unit 52, game elements can be added to the processing by the function units 12 and 32 which tends to be monotonous, The user can do while enjoying the processing by the function units 12 and 32. In addition, the user is requested to continue the processing by the functional units 12 and 32 until all unprocessed illustrations 71 disappear from the face area of the display unit 52 or until the processed illustration 72 is added to the entire processed portion. It is possible to prevent partial processing shortage from occurring.

  The auxiliary illustration 70 includes the unprocessed illustration 71 representing the exaggerated hair, adds the unprocessed illustration 71 to the face area shown on the display unit 52 before the hair removal processing by the functional unit 12 is started, and the functional unit The unprocessed illustration 71 is deleted in order from the part of the face area where 12 has passed a predetermined number of times. According to this, the user can perform while enjoying the hair removal process, and in addition, prompts the user to continue the hair removal process until all unprocessed illustrations 71 are erased from the face area, so that the partial process is performed. It is possible to prevent a shortage from occurring. When all unprocessed illustrations 71 are erased from the display unit 52, the user can confirm that the hair removal processing of the entire face is finished.

  The supplementary illustration 70 changes the beauty of the appearance of the face area, and as the cosmetic processing by the function unit 32 progresses, the supplementary illustration 70 added to the face area is changed so that the appearance of the face area becomes beautiful. According to this, it is possible for the user to perform while enjoying the cosmetic processing, and to prompt the user to continue the cosmetic processing until the appearance of the face area is beautiful, and to prevent the partial processing shortage from occurring.

  According to the moving picture stopping means for stopping the moving picture shown on the display unit 52, the user stops the moving picture in a state in which the part of the face to be checked is projected on the camera 53, and By moving the position to an easy position, it is possible to easily check the site. In particular, even if it is a part under the chin which is difficult to check with a normal hand mirror, the check can be easily performed.

  When the moving image shown on the display unit 52 is stopped and checked, it is usual to interrupt the processing by the function units 12 and 32 and to keep driving the function units 12 and 32 even during the check is power consumption There is a lot of waste, such as increasing If the moving image is stopped in conjunction with the stop operation of the function units 12 and 32 as in the present invention, the function units 12 and 32 can be stopped while the moving image is stopped, and the generation of the above waste can be prevented. In addition, it is not necessary to separately perform the operation of stopping the moving image and the operation of stopping the function units 12 and 32, it is possible to reduce the time and effort of the user. Furthermore, when the functional units 12 and 32 are stopped while the moving image is stopped, the user can check the still image in a calm state without worrying about the driving sound of the functional units 12 and 32.

  If the display unit 52 of the display device 5 is turned off when a predetermined time has elapsed since the moving image is stopped, the display is performed after the user has finished using the small electric devices 1 and 2 and stops the use of the small electric devices 1 and 2 When the unit 52 is not turned off, it is possible to reduce the power consumption of the display device 5 by preventing the waste that keeps lighting the display unit 52.

  It is easier to photograph the lower part of the face where the whiskers grow, especially the lower jaw, when the camera 53 is positioned below the display device 5 than when the camera 53 is positioned above the display device 5. . Therefore, when the display unit 52 is used like a hand mirror at the time of shaving, it is preferable to set the display device 5 in the reverse posture.

  The smartphone (display device) 5 includes a thin case 50 whose upper and lower dimensions are larger than the left and right dimensions, and the front surface 51 of the case 50 is provided with a touch panel display (display unit) 52 that occupies most of the front It is done. A camera 53 and a speaker 54 are disposed at the left and right center of the upper portion of the front surface 51, and an LED (lighting device) 56 is disposed at the right of the both 53 and 54. Inside the housing 50, a vertically long control board 57, a vibrator 59, and a battery pack (not shown) which is a power source of the entire smartphone 5 are accommodated. The control board 57 includes, in addition to a wireless interface for communicating with the base station, a memory 61 for storing various programs and data, an acceleration sensor 62 and a gyro sensor 63 for detecting the attitude of the smartphone 5, Bluetooth A communication interface 64 operating in accordance with the above standard and a control unit 65 for controlling the entire smartphone 5 including these components are mounted.

  The memory 61 of the smartphone 5 stores a camera program for displaying the moving image photographed by the camera 53 on the display 52. The camera program includes a zoom function of enlarging and reducing a moving image captured by the camera 53, and a face recognition function of detecting a face area from the moving image captured by the camera 53. The zoom method by the zoom function may be either optical zoom or digital zoom, or both.

  The memory 61 also stores an auxiliary application which is an application program for assisting the user in using the electric razor 1. The auxiliary application is provided by the maker of the electric razor 1, and can be downloaded to the smartphone 5 via the Internet from a server operated by the maker. The auxiliary application includes mirroring means for making the display 52 available as a mirror, moving picture stopping means for holding a moving image shown on the display 52, and illumination control means for controlling the lighting state of the LED 56. In addition, the auxiliary application includes zoom control means for controlling the zoom function of the camera 53, illustration addition means for adding the auxiliary illustration 70 (see FIG. 10) to the face area shown on the display 52, and instructs the user to upside down the smartphone 5 And reverse instruction means. Furthermore, the auxiliary application includes device state notification means for displaying the device state of the electric razor 1 on the display 52, electric device control means for transmitting a control signal for controlling the electric razor 1 to the control unit 25, and electricity for the display 52 A manual display means for displaying a manual of the razor 1 is provided. This auxiliary application is a resident type application program, and is in a standby state in the background until the operation is started in conjunction with the on operation of the drive switch 21 of the electric razor 1.

(Mirroring means)
The mirroring means activates a camera program stored in the memory 61 to start photographing by the camera 53, and displays a moving image photographed by the camera 53 on the display 52. During execution of the camera program, the face of the user facing the front face 51 of the smartphone 5 is photographed by the camera 53 and projected on the display 52, so that the user can use the display 52 as if it were a mirror. The mirroring means is the core of the auxiliary application, and starts operation simultaneously with the activation of the auxiliary application.

(Video still means)
The moving picture stationary means stops the moving picture shown on the display 52 according to the operation of the user during the operation of the mirroring means. Specifically, when the user turns off the drive switch 21 while the electric shaver 1 is driven, the moving picture stationary means stops the moving picture shown on the display 52, and when the user turns on the driving switch 21 again, the moving picture stationary means Release the stillness of the video. The fact that the drive switch 21 has been operated is transmitted from the control unit 25 of the electric razor 1 to the smartphone 5 via the communication interface 24 and 64. The user turns off the drive switch 21 to stop the moving image and moves the display 52 in a stationary state to a position such as the front of the face in a state where the portion of the face to be checked is projected on the camera 53. , The said site | part can be checked easily.

(Lighting control means)
The illumination control means performs control of lighting the LED 56 of the smartphone 5 in a state in which the connection between the electric razor 1 and the smartphone 5 is established. The LED 56 is provided with a plurality of lighting patterns, and in the present embodiment, when the electric razor 1 is driven (a state in which a moving image appears on the display 52), the LED 56 is lit in the first lighting pattern. The LED 56 is turned on in the second lighting pattern on the display 52 (still state of moving image). Further, in the present embodiment, the first lighting pattern is constantly lit, and the second lighting pattern is blinked of the same color, but for example, both lighting patterns are constantly lit and their color tone (emission color ) May be different. In the present embodiment, since the camera 53 and the LED 56 are disposed on the same side (front surface 51) of the smartphone 5, when using the electric razor 1 and the smartphone 5 in a dimly lit place, the shooting target of the camera 53; Can be illuminated. Therefore, regardless of the brightness of the place where the electric razor 1 and the smartphone 5 are used, the user's convenience can be improved by always reflecting the user's face clearly on the display 52. The illumination device 56 in the present invention is not limited to the one incorporated in the smartphone 5 as in this embodiment, but is a concept including one externally attached to the smartphone 5 and controlled by an auxiliary application.

  As shown in the flowchart of FIG. 3, when the user turns on the drive switch 21 to turn on the power of the electric razor 1 (YES in step S1), the motor 16 is activated and the functional unit 12 starts driving. At the same time, the communication interface 24 of the electric shaver 1 is activated (step S2), and a wireless connection with the communication interface 64 of the smartphone 5 is established. The smartphone 5 is activated when the power of the electric razor 1 is turned on, and the communication interface 64 is also activated. In addition, an auxiliary application that assists the use of the electric razor 1 is in a standby state in the background.

  In response to the establishment of the connection with the electric razor 1, the auxiliary application confirms the state of the control unit 65 of the smartphone 5, and displays a push notification on the display 52. The display of the push notification corresponds to the activation of the auxiliary application in the present invention (step S3). By tapping the push notification, the user can shift the auxiliary application to the foreground and display the screen of the auxiliary application on the entire display 52. When the auxiliary application is activated in the foreground, the mirroring means starts operation, and the moving image photographed by the camera 53 is displayed on the display 52 (step S4). Further, the illumination control means turns on the LED 56 in the first lighting pattern (step S5).

  When the mirroring means starts operation, the moving picture stationary means enters a standby state, and waits for the drive switch 21 of the electric razor 1 to be turned off (step S6). When the drive switch 21 is turned off and the motor 16 is stopped (YES in step S6), the moving picture stationary means stops the moving picture shown on the display 52 (step S7), and the illumination control means switches the LED 56 to the second lighting pattern. (Step S8). When the drive switch 21 is turned on and the motor 16 is activated again (YES in step S9), the moving picture stationary means cancels the stationary state of the moving picture (step S10), and the illumination control means sets the LED 56 to the first lighting pattern. Switching (step S5), it waits for the drive switch 21 to be turned off again in step S6.

  The control unit 25 of the electric razor 1 continues the valid state of the communication interface 24 immediately after the drive switch 21 is turned off, and communicates when a predetermined time (10 minutes in this embodiment) elapses from the turn off operation. Disable the interface 24. However, the control unit 25 has a timer function to stop the motor 16 when the continuous driving time of the motor 16 exceeds a predetermined time (five minutes in this embodiment), and the motor 16 is stopped by this timer function. In this case, the communication interface 24 is invalidated after a lapse of a time (five minutes in the present embodiment) shorter than the predetermined time from the time of stopping.

  The smartphone 5 stores a protection program for turning off the display 52 when it is considered that the user has left the smartphone 5 for a long time. If the moving picture stationary means is operating for a long time while the auxiliary application is running, that is, if the moving image shown on the display 52 is stationary for a long time, the user finishes shaving and the electric razor 1 There is a possibility that the smartphone 5 is left without turning off the display 52.

  On the other hand, when the moving picture stationary means is not in operation and the moving picture is shown on the display 52, ie, in the mirrored state of the display 52, the user uses the smartphone 5 like a hand mirror while using the electric razor 1 There is a high possibility of shaving. However, even in the mirror state, if the user's face and the electric razor 1 do not appear in the camera 53 for a long time, the user may leave the smartphone 5 together with the electric razor 1 in the driven state. In these cases, the protection program turns off the display 52 to avoid wasting the battery pack.

  A specific control procedure by the protection program is shown in the flowchart of FIG. The protection program starts counting by the timer at a point in time when the auxiliary application is started in the foreground (at this point, the mirroring means is operating and the moving picture stationary means is not operating) (step S11). The subsequent protection program starts the timing, or a predetermined time (five minutes in the present embodiment) elapses, or the moving picture stationary means operates to make the display 52 stand still, or the face of the user with the camera 53 Alternatively, it waits for the electric razor 1 to be detected (steps S12 to S14).

  If the user's face or the electric razor 1 is detected from the moving image shown on the display 52 before the predetermined time elapses (NO in steps S12 to S13, YES in step S14), the user is using the smartphone 5 Since it is assumed, the process returns to step S11, resets the timer, and starts timing again. On the other hand, when the predetermined time has elapsed without detecting the user's face or the electric razor 1 and without the display 52 standing still (NO in steps S13 to S14, YES in step S12), the user is in the driving state Since it is assumed that the smartphone 5 is left together with the electric razor 1, the protection program proceeds to step S15 to turn off the display 52.

  If the moving picture stationary means operates and the display 52 is stationary (YES in step S13), the process proceeds to step S16 to reset the timer and start timing again. When the predetermined time (five minutes in the present embodiment) has elapsed before the stop of the stationary state after the start of time counting (NO in step S18, YES in step S17), the user finishes shaving and the electric Since it is assumed that the smartphone 5 is left without turning off the display 52 after stopping the razor 1, the protection program proceeds to step S15 and turns off the display 52. On the other hand, when the stationary state is released before the predetermined time elapses (NO in step S17, YES in step S18), the process returns to step S11, the timer is reset, and clocking is started again. Besides the above, the protection program can turn off the display 52 when the motor 16 is stopped by the timer function of the electric razor 1.

  The timing chart of FIG. 5 shows an example of a situation in which the drive switch 21 of the electric razor 1 and the auxiliary application of the smartphone 5 are interlocked. When the drive switch 21 is turned on at time t1, the electric shaver 1 activates the motor 16 and the communication interface 24 is activated. At the same time, in the smartphone 5, an auxiliary application waiting in the background causes the display 52 to display a push notification. Then, through tap operation by the user, the auxiliary application is activated in the foreground, and the display 52 is mirrored by the mirroring unit. Further, the LED 56 lights up in the first lighting pattern. At the next time point t2 (t2-t1 <5 minutes), the drive switch 21 is turned off, whereby the motor 16 of the electric shaver 1 is stopped. At the same time, in the smartphone 5, the moving image shown on the display 52 is stopped, and the LED 56 is switched to the second lighting pattern.

  At the next time point t3 (t3−t2 <5 minutes), the drive switch 21 is turned on to start the motor 16 of the electric shaver 1 again. At the same time, in the smartphone 5, the stillness of the moving image by the moving image holding means is released, the display 52 is mirrored again, and the LED 56 is switched to the first lighting pattern. At the next time point t4 (t4-t3 <5 minutes), the drive switch 21 is turned off, the motor 16 is stopped as in the previous time point t2, the moving image of the display 52 is stopped, and the LED 56 is turned on. Switch to the lighting pattern. At the next time point t5 (t5-t4 = 5 minutes), the display 52 is turned off by the above-mentioned protection program. At the next time point t6 (t6-t4 = 10 minutes), the communication interface 24 of the electric razor 1 is deactivated. Further, in the smartphone 5, in response to the disconnection from the electric razor 1, the auxiliary application automatically shifts to the background standby state, and the LED 56 is turned off. The timing of turning off the LED 56 may be time t5 when the display 52 is turned off.

  The timing chart of FIG. 6 shows the case where the electric razor 1 is left with the smartphone 5 executing the auxiliary application while the electric razor 1 is in the driven state. A time t12 when the electric razor 1 and the smartphone 5 are left is several minutes after the time t11 when the drive switch 21 is turned on (2 to 3 minutes). In the electric shaver 1, the motor 16 is automatically stopped at time t13 five minutes after the on operation of the drive switch 21 (time t11), and the communication interface 24 is invalidated at time t15 five minutes after time t13. Be The smartphone 5 can not detect the user's face or the electric shaver 1 with the camera 53 after time t12 when left by the user, so the display 52 is displayed by the above-mentioned protection program at time t14 five minutes after time t12. It is turned off. In addition, at time t15 when the connection with the electric razor 1 is disconnected, the auxiliary application automatically shifts to the background standby state, and the LED 56 is turned off. When the camera 53 detects the user's face or the electric razor 1 before time t14, ie, before 5 minutes from time t12, the timer for turning off the display 52 is reset. Further, the timing of turning off the display 52 by the protection program of the smartphone 5 may be time t13 at which the motor 16 of the electric razor 1 is automatically stopped. The timing at which the communication interface 24 is disabled, the timing at which the auxiliary application shifts to the background standby state, and the timing at which the LED 56 is turned off may also be at time t13.

  The timing chart of FIG. 7 shows another control method by the auxiliary application and the protection program of the smartphone 5. From time t21 when the drive switch 21 is turned on until time t22 when the camera 53 can not detect the user's face or the electric shaver 1 is the same as time t11 to t12 in FIG. At time t23 after one minute, the protection program causes the display 52 to be turned off, and the electric device control means (described in detail later) of the auxiliary application performs a control signal for decelerating the motor 16 to the control unit 25 of the electric shaver 1. Send to Then, at time t24 one minute after time t23, the motor 16 is stopped in the electric shaver 1 and the communication interface 24 is invalidated in the electric shaver 1, and the auxiliary application shifts to the standby state in the background in the smartphone 5 and the LED 56 is turned off. Do. If the camera 53 detects the user's face or the electric razor 1 before time t23, that is, one minute from time t22, the timer for turning off the display 52 is reset. Further, instead of decelerating the motor 16 at time t23, the motor 16 may be stopped, in which case the invalidation of the communication interface 24, transition of the auxiliary application to the standby state, and extinguishing of the LED 56 are also performed at time t23. Can be done.

  The operation for controlling the moving picture stationary means is not limited to the switch operation of the electric shaver 1 described above, and may be, for example, a tap operation of the display 52 of the smartphone 5 by the user. It may be a specific move operation such as shaking 5. These movement operations are detected by acceleration sensors 22 and 62 and gyro sensors 23 and 63 incorporated in the electric razor 1 and the smartphone 5 respectively. The content of the movement operation of the electric razor 1 is transmitted from the control unit 25 to the smartphone 5 via the communication interface 24 or 64.

(Zoom control means)
The zoom control means controls the zoom function of the camera 53 in conjunction with the moving operation of the electric razor 1 and the smartphone 5 by the user. The movement operation of the electric razor 1 is detected by the acceleration sensor 22 and the gyro sensor 23 built in the electric razor 1, and the contents thereof are transmitted from the control unit 25 to the smartphone 5 via the communication interface 24 and 64. The zoom control means controls the zoom function of the camera 53 based on the contents of this movement operation. For example, if the electric razor 1 is moving with a relatively large stroke, or if the electric razor 1 is moving relatively fast, it is assumed that the user is shaving a wide range of beards on the face, so zoom The control means zooms out the camera 53 to display a wide area of the face on the display 52. Conversely, if the razor 1 is moving with a relatively small stroke, or if the razor 1 is moving relatively slowly, it is assumed that the user is intensively shaving the beard of a part of the face Therefore, the zoom control means causes the camera 53 to zoom in and display a part of the face on the display 52 in an enlarged manner.

  In addition, the moving image captured by the camera 53 can be analyzed to detect the moving operation of the electric razor 1 by the user. In order to facilitate this detection, the outer surface of the electric razor 1 is provided with a plurality of markings 28 which can be identified in the animation (see FIG. 8). The marks 28 are mainly disposed dispersively around the functional unit 12 so that some marks 28 always appear on the camera 53 regardless of the grip posture of the electric razor 1 by the user. By observing the movement of each mark 28 in the moving image, the movement stroke and movement speed of the electric razor 1 can be detected, and the zoom function can be controlled in the same manner as above based on their sizes.

  Further, as shown in FIG. 8, when the face recognition function of the camera program is used in combination, the functional part 12 of the electric razor 1 compares the positional relationship between the face area in the moving image and each mark 28 of the electric razor 1. It is possible to detect the part of the face that faces directly. The zoom function of the camera 53 may be controlled according to the part of the face detected by this method. In FIG. 8, the functional unit 12 faces the user's nose, which is detected from the positions of two marks 28 around the functional unit 12 in the face area. When the functional unit 12 is located below the nose, the zoom control means zooms in on the camera 53, for example, to enlarge and display the nose on the display 52. Usually, it is less likely to shave the beard at the same time in the nose and at other parts at the same time, and often it is concentrated on shaving the beard in the nose.

  On the other hand, the movement operation of the smartphone 5 is detected by the acceleration sensor 62 and the gyro sensor 63 built in the smartphone 5, and the zoom function is controlled based on the contents of the movement operation. Specifically, for example, as shown in FIG. 9A, when the front surface 51 of the smartphone 5 is at an angle close to vertical, the user moves the smartphone 5 to the front of the face to display the entire face The zoom control means zooms out the camera 53 because it is assumed that the image is to be displayed at 52. Conversely, as shown in FIG. 9B, when the front surface 51 of the smartphone 5 is approximately 45 ° with respect to the horizontal plane, the user moves the smartphone 5 diagonally below the face to make it possible to The zoom control means causes the camera 53 to zoom in as it is assumed that only a portion is to be displayed on the display 52. In addition, when the sensor 62/63 detects that the user has performed a specific moving operation such as shaking the smartphone 5, control may be performed to change the zoom magnification of the camera 53.

  The moving operation of the smartphone 5 can also be detected using the face recognition function of the camera program. That is, when the face area in the moving image captured by the camera 53 becomes large, it can be considered that the user brings the smartphone 5 close to the face. In this case, the zoom control means zooms in the camera 53, for example. The part of the face is enlarged and projected. On the contrary, when the face area in the moving image becomes smaller, it can be considered that the user moves the smartphone 5 away from the face, and in this case, the zoom control means zooms out the camera 53, for example. Reflect on the display 52. Furthermore, the zoom function of the camera 53 may be controlled in accordance with the expression of the face area in the moving image. For example, when the face area is recognized as a smile, the zoom control means zooms in the camera 53, and when the face area is recognized as an angry face, the zoom control means zooms out the camera 53. Let

  The above zoom control means may start the operation simultaneously with the activation of the auxiliary application, or may start the operation according to the user's request after the activation of the auxiliary application. The operation for controlling the zoom control means is not limited to the movement operation of the electric razor 1 and the smartphone 5 described above. For example, the zoom function of the camera 53 is interlocked with the switch operation on the electric razor 1 side. Can be controlled. An example of the switch may be a control switch for controlling the number of rotations of the motor 16 provided in the electric shaver 1. For example, when an operation to reduce the number of rotations is performed, the user is careful about the beard of a part of the face Since it is assumed that shaving is performed, the zoom control means zooms in the camera 53. Also, the zoom function of the camera 53 can be controlled by the user by directly operating the display 52 or the side button of the smartphone 5.

(Illustration means)
The illustration adding means adds the auxiliary illustration 70 to the face area reflected on the display 52 of the smartphone 5 as shown in FIG. The auxiliary illustration 70 according to the present embodiment is configured of an unprocessed illustration 71 representing an exaggerated beard and a processed illustration 72 indicating that the beard has been shaved. When the illustration addition means starts to operate, the unprocessed illustration 71 is added to the lower nose, jaws, both cheeks, and sideburns of the face area detected by the face recognition function, and shaving of each part by the user is completed. If so, the unprocessed illustration 71 of that portion is changed to the processed illustration 72. The user can confirm that all the beards have been shaved (there is no shaving) when all the unprocessed illustrations 71 on the display 52 are changed to the processed illustrations 72.

  The completion of shaving of each part of the face is detected using the marks 28 on the outer surface of the electric razor 1. As described above in the item of the zoom control means, when the positional relationship between the face area in the moving image and each mark 28 of the electric razor 1 is compared, the functional part 12 of the electric razor 1 can detect the part of the face facing the front . The illustration adding means changes the unprocessed illustration 71 to the processed illustration 72, judging that shaving of the part is completed when the function part 12 faces the part of the face, ie, the number of times it passes a predetermined number of times Do.

  The illustration adding means may start the operation simultaneously with the activation of the auxiliary application, or may start the operation according to the user's request after the activation of the auxiliary application. Further, the auxiliary illustration 70 may be configured by only one of the unprocessed illustration 71 and the processed illustration 72. For example, in the case where the auxiliary illustration 70 is configured by only the unprocessed illustration 71, the illustration adding means completes shaving. The unprocessed illustration 71 is deleted in order from the part judged to have been done. The user can confirm that all the beards have been shaved when all the unprocessed illustrations 71 disappear from the display 52. Further, the auxiliary illustration 70 can include an in-process illustration indicating that the process is in progress. For example, the auxiliary illustration 70 includes a plurality of in-process illustrations in which the whiskers are gradually thinned compared to the unprocessed illustration 71, and each time the functional unit 12 of the electric razor 1 passes through a part of the face The auxiliary illustration 70 of can be changed to an illustration during thin processing of a beard.

(Reverse instruction means)
The reverse instruction means instructs the user who uses the auxiliary application with the smartphone 5 in the normal posture to reverse the vertical direction of the smartphone 5. The normal posture is a posture in which the camera 53 and the LED 56 are positioned above the smartphone 5 as shown in FIG. When the smartphone 5 is turned upside down, the camera 53 is located at the lower part of the smartphone 5, so that it is easy to photograph the lower part of the face where the beard grows, especially the lower jaw. The fact that the smartphone 5 is in the normal posture or the reverse posture is detected by the built-in gyro sensor 63.

  For example, as shown in FIG. 11A, when the smartphone 5 is in the normal posture, the inverted character of the upside down can be displayed on the display 52, and this can be used as the inversion instruction means. When the user who looks at the reverse character inverts the smartphone 5 up and down intuitively, as shown in FIG. 11B, the display 52 displays normal characters in the correct direction. Note that the normal characters in FIG. 11B may get in the way when the time passes because they may get in the way when displaying the user's face on the display 52, and may be omitted.

  Further, as shown in FIG. 12A, when the smartphone 5 is in the normal posture, characters such as “Please reverse” are displayed on the display 52 to directly instruct the user to upside down the smartphone 5 And this can be used as reverse indication means. When the user turns the smartphone 5 upside down according to this character, as shown in FIG. 12 (b), a character indicating that the attitude of the smartphone 5 is appropriate is displayed on the display 52. For the same reason as the normal letter b), it may disappear after a lapse of time or may be omitted. In place of the characters in FIG. 12A, for example, a symbol such as a U-shaped arrow may be displayed and used as a reverse instruction means.

  Moreover, as shown to Fig.13 (a), when the smart phone 5 is a normal attitude | position, the whole moving image on the display 52 can be turned upside down, and this can be used as a inversion instruction means. When the user who looks at his face turned upside down inverts the smart phone 5 intuitively up and down, as shown in FIG. 13B, the display 52 displays a moving picture in the correct direction. Here, as in FIG. 12 (b), characters may be displayed to indicate that the attitude of the smartphone 5 is appropriate.

(Device status notification means)
The device state notification means causes the display 52 to display the device state such as the remaining battery level of the electric razor 1 as shown in FIG. This display includes a battery remaining amount display 75 indicating the remaining amount of the secondary battery 18 of the electric razor 1, a replacement display 76 indicating the replacement time of the outer cutter 13 and the inner cutter 14, and a functional unit 12 including a shavings storage chamber. And a load display 78 indicating the size of the load acting on the functional unit 12, a time display 79 for displaying the continuous use time of the electric razor 1, and the like. The device state notification means starts the operation simultaneously with the activation of the auxiliary application, but can also stop the operation according to a subsequent user operation.

  The battery remaining amount display 75 includes a numerical value indicating the remaining amount of the secondary battery 18 and a scale of five upper and lower steps, and the color tone changes from green to yellow to red as the battery remaining amount decreases. Information on the remaining amount of the secondary battery 18 is transmitted from the control unit 25 of the electric razor 1 to the smartphone 5 via the communication interface 24 and 64. When the remaining battery level falls below a predetermined rate (for example, 20%), the device status notifying means changes the color tone of the remaining battery level display 75 to red, drives the vibrator 59 of the smartphone 5, and further turns the LED 56 in an emergency. It lights up in a pattern and informs the user that the battery level is low.

  The replacement display 76 does not light up when the blades 13 and 14 need not be replaced, and lights up when the replacement time approaches. The control unit 25 of the electric shaver 1 manages the cumulative use time from the previous replacement for each of the outer blade 13 and the inner blade 14, and when the cumulative use time reaches a predetermined time, It transmits to the smartphone 5 that the replacement time is approaching. The device status notification means receives the information, causes the display 52 to light the replacement display 76 about the blade 13 or 14 whose replacement time is approaching, drives the vibrator 59, and lights the LED 56 in the emergency pattern, Prompt the user to replace the blade 13.14. After the user has replaced the blades 13 and 14, for example, when the replacement display 76 on the display 52 is pressed for a long time, the device status notification means considers that the replacement of the blades 13 and 14 is complete and turns off the replacement display 76. It is transmitted to the control unit 25 of the electric razor 1 that the replacement of the blades 13 and 14 is completed. The control part 25 which received this resets the accumulated use time about the replaced blade 13 * 14. In addition to the accumulated use time, it may be determined based on the number of times the drive switch 21 is turned on and off that the blade 13 and 14 have come to be replaced.

  The washing indication 77 is also not lit at a time when washing of the functional unit 12 is unnecessary, and turns on when the washing time approaches. An optical sensor for detecting the accumulation condition of the shavings is provided in the shavings storage chamber constituting the functional unit 12, and when the accumulation condition of the shavings exceeds a predetermined reference value, the control unit 25 performs cleaning It transmits to the smartphone 5 that the time has come. The device state notification means having received this causes the display 52 to light on the display 52, drives the vibrator 59, and causes the LED 56 to light in an emergency pattern to urge the user to wash the functional unit 12. When the user performs cleaning and the degree of accumulation of the chips becomes equal to or less than a predetermined value, the control unit 25 transmits the completion of the cleaning to the smartphone 5, and the device state notification means having received this turns off the cleaning display 77. . It should be noted that the approaching of the cleaning time of the functional unit 12 may be determined based on the cumulative use time from the previous cleaning and the number of times the drive switch 21 is turned on and off, in addition to the accumulation of the shavings.

  The load display 78 displays the size of the load acting on the functional unit 12 of the electric razor 1, thereby promoting adjustment of the strength of the force with which the user presses the functional unit 12 against the face skin. There is a correlation between the pressing force of the functional unit 12 and the magnitude of the load, and the stronger the pressing force, the larger the load. Therefore, when the magnitude of the load of the functional unit 12 is displayed on the display 52, the user can be notified of the strength of the pressing force at that time. By shaving while checking the load display 78, the user can maintain the pressing force of the functional unit 12 always at an appropriate strength, and can reduce the load on the face and skin.

  A load current flowing through the motor 16 is employed as an index of the size of the load of the functional unit 12. As the load on the function unit 12 increases, the value of the load current also increases. The control unit 25 of the electric razor 1 transmits the load current to the smartphone 5 while monitoring the magnitude of the load current. The load display 78 consists of an arc-shaped scale indicating the size of the load and a pointer pointing to one point of the scale, and indicates that the load is small (pressing force is weak) from the lower left to the lower right of the scale. The low load zone (green), the medium load zone (blue) indicating that the load (pressing force) is appropriate, and the high load zone (green) indicating that the load is large (strong pressing force) An overload zone (red) indicating that the pressing force is excessive is set in order. The user preferably adjusts the pressing force of the functional unit 12 so that the pointer always points to the medium load zone. When the pointer of the load display 78 points to the overload zone, the device status notification means drives the vibrator 59 and turns on the LED 56 in an emergency pattern to alert the user.

  When the user taps on the load display 78 on the display 52, the load display 78 switches to the second load display 80 shown in FIG. The second load display 80 is composed of two concentric circularly arranged scale marks and an arrow pointing to one point of each scale. The outer scale indicates the number of revolutions of the motor 16 and the inner scale indicates the magnitude of the load torque, and the information is transmitted from the control unit 25 of the electric shaver 1 to the smartphone 5. When the number of revolutions of the motor 16 falls below a predetermined lower limit, or when the load torque exceeds a predetermined upper limit, the device state notification means considers that the load applied to the function unit 12 is excessive and causes the vibrator to 59 is driven and the LED 56 is lighted in an emergency pattern to alert the user. When the user taps on the second load display 80 on the display 52, the second load display 80 returns to the load display 78 shown in FIG.

  The time display 79 displays the continuous use time per one time of the electric razor 1, that is, the continuous drive time of the motor 16 in seconds. When the user turns off the drive switch 21 to stop the motor 16, the continuous use time displayed by the time display 79 is reset. Also when the motor 16 is stopped by the above timer function after a predetermined time (five minutes) has elapsed since the drive switch 21 is turned on, the continuous use time is similarly reset. The device status notification means changes the time display 79 to, for example, red when one minute before the motor 16 is stopped by the timer function, drives the vibrator 59, and turns on the LED 56 in an emergency pattern, Alert the user. The continuous use time may be measured on the side of the electric razor 1 and transmitted to the smartphone 5 or may be measured on the side of the smartphone 5. As described above, the fact that the drive switch 21 is turned on or off is transmitted to the smartphone 5, so measurement of the continuous use time is also possible on the smartphone 5 side.

(Electric device control means)
The electric device control means transmits a control signal for controlling the electric shaver 1 to the control unit 25 via the communication interface 24. At the left end of the display 52, a rotation number lever 81 for changing the rotation number of the motor 16 of the electric shaver 1, a drive button 82 for turning the motor 16 on and off, and the above-described ones operable by the user A lock button 83 is provided to lock the motor 16 in the driven state regardless of the timer function of the.

  When the user slides the rotational speed lever 81 up and down, the electric device control means transmits a control signal for accelerating or decelerating the motor 16 to the control unit 25 of the electric shaver 1 via the communication interface 24 or 64. . When the user taps the drive button 82 in the stopped state of the motor 16, the electrical device control means transmits a control signal for activating the motor 16 to the control unit 25. Further, when the user taps the drive button 82 in the driving state of the motor 16, the electric device control means transmits a control signal for stopping the motor 16 to the control unit 25. When the user taps the lock button 83 in the driving state of the motor 16, the electric device control means transmits a control signal for locking the motor 16 to the control unit 25 if the motor 16 is not locked in the driving state, If the motor 16 is locked in the driving state, a control signal for releasing the lock is sent to the control unit 25. When the motor 16 is locked in the driving state, even if the user inadvertently touches the switch button 15, the motor 16 does not stop against the user's intention.

  Besides the above, the electric device control means can control the electric razor 1 in accordance with the displacement operation of the smartphone 5 by the user. For example, when the user tilts the smartphone 5 to the left or right, the electric device control means transmits a control signal to accelerate the motor 16 to the control unit 25 and when the user tilts the smartphone 5 to the other left, the electric device control The means transmits to the control unit 25 a control signal for decelerating the motor 16. The movement operation of the smartphone 5 by the user can be detected by the acceleration sensor 62 or the gyro sensor 63 built in the smartphone 5.

  In addition, the electric device control means sets the motor 16 to a low speed, for example, when the functional unit 12 of the electric razor 1 faces the user's face under the nose, or the motor 16 according to the part of the face the functional unit 12 faces. Can control the number of rotations of As described above in the item of the zoom control means, when the positional relationship between the face area in the moving image and each mark 28 of the electric razor 1 is compared, the functional part 12 can detect the face part facing the face. Furthermore, as described in the timing chart of FIG. 7, when the user is considered to leave the electric razor 1 or the smartphone 5 as described in the timing chart of FIG. Can be transmitted to the control unit 25.

(Instructions display means)
The instruction display means causes the display 52 of the smartphone 5 to display the instruction manual of the electric razor 1. When the user taps the instruction button 85 (see FIG. 14) on the display 52, the instruction display means switches the display 52 from the mirror display to the instruction display shown in FIG. A mirror button 86 is disposed at a corner of the display 52 in the instruction display, and when the user taps the mirror button 86, the instruction display switches the display 52 from the instruction display to the mirror display.

  The instruction manual in the present embodiment is composed of a plurality of pages such as “table of contents”, “name and function of each part”, “how to use”, “replacement of blade”, “cleaning of blade” and the like. Since the table of contents is displayed immediately after the display 52 is switched to the manual display, the user taps the link to each page included in the table of contents or slides the display 52 to the left or right to make the desired page The page can be displayed on the display 52, and the page can be reduced by the pinch-in operation and the page can be enlarged by the pinch-out operation. In addition, in place of or in addition to the instruction button 85 of the present embodiment, a plurality of buttons such as “How to use”, “replacement of blade”, “cleaning of blade” and the like are arranged on the display 52 When the user taps each button, the corresponding page of the instruction manual may be displayed. The data of the instruction manual may be included in advance in the auxiliary application, or may be downloaded from the server of the maker of the electric shaver 1 via the Internet when tapping the instruction button 85.

  In the flowchart of FIG. 17, immediately after the auxiliary application is activated on the smartphone 5, the display 52 is a mirror display. When the instruction sheet button 85 on the display 52 is tapped (YES in step S21), the instruction display means switches the display 52 from the mirror display to the instruction display (step S22). At the same time, the control unit 25 stops the motor 16 in accordance with the control signal transmitted from the electric device control unit to the electric shaver 1 (step S23). Thereafter, the process waits until the drive switch 21 of the electric razor 1 is turned on or the mirror button 86 on the display 52 is tapped (steps S24 to S25).

  When the drive switch 21 of the electric shaver 1 is turned on (YES in step S24), the process proceeds to step S26, and the control unit 25 activates the motor 16. The fact that the drive switch 21 is turned on is transmitted from the control unit 25 to the smartphone 5 via the communication interface 24 or 64, and the instruction display unit that has received it switches the display 52 from the instruction display to the mirror display. . If the mirror button 86 on the display 52 is tapped (YES in step S25), the process also proceeds to step S26, and the instruction sheet display means switches the display 52 to mirror display. At the same time, the control unit 25 starts the motor 16 in accordance with the control signal transmitted from the electric device control means to the electric shaver 1.

Second Embodiment FIG. 19 shows a second embodiment of the interlocking system according to the present invention. The razor head 11 of the electric razor 1 according to the second embodiment includes a pair of front and rear functional units 12, and a skin elasticity sensor (skin elasticity measuring unit) 40 is provided between the two functional units 12. The functional unit 12 comprises an outer blade (cutting blade) 13 and an inner blade (cutting blade) 14. Various kinds of conventionally known sensors can be used as the skin elasticity sensor 40. For example, the vibrator sensor disclosed in JP 2009-153727 A, the feeling disclosed in JP 61-181437 A A pressure sensor can be mentioned. The skin elasticity sensor 40 according to the present embodiment is composed of a contactor 41 contacting the skin surface simultaneously with the outer blade 13 and a spring 42 biasing the contactor 41 toward the skin surface. The skin elasticity sensor (skin elasticity measuring means) 40 may be provided on the left and right portions of the functional unit 12 in the case body constituting the razor head 11 as long as it can contact the skin surface simultaneously with the functional unit 12.

  On the side of the main body case 10, a skin elasticity notification unit 43 that displays the size of the skin elasticity in three stages of "small", "medium", and "large" is provided. The skin elasticity notification unit 43 is configured of three LEDs mounted on the control substrate 17, and these LEDs correspond to "small", "medium", and "large", respectively. The main body case 10 is provided with a light transmission window facing each LED, and the user can visually recognize the light emission state of each LED through the light transmission window. The control unit 25 of the electric razor 1 performs control to turn on any one LED of the skin elasticity notification unit 43 according to the size of the skin elasticity measured by the skin elasticity sensor 40.

  The skin elasticity notification unit 43 can also be provided on the razor head 11. The skin elasticity notification unit 43 in this case is configured of, for example, one LED that emits light of three colors, and the LEDs are "blue" and "green" corresponding to "small", "medium" and "large" of the skin elasticity. The user can be notified of skin elasticity by changing the color to "red". When the skin elasticity notification unit 43 is provided in the razor head 11 as described above, the user can easily recognize the light emission state and easily check the skin elasticity state. The skin elasticity notification unit 43 provided on the side of the main body case 10 for light emission display may be hidden by the user's hand holding the main body case 10, but when arranged on the razor head 11, the possibility is present Few. When using the electric razor 1, it is preferable to provide a skin elasticity notification unit 43 on the rear surface (rear surface) of the razor head 11, since the rear surface is mainly reflected in the mirror. Alternatively, it is preferable that the skin elasticity notification unit 43 be provided inside the razor head 11 and light be emitted through the transparent portion (including the semitransparent portion) of the case body constituting the razor head 11 or the outer blade 13. According to these configurations, the user can easily visually recognize the light emitted by the skin elasticity notification unit 43 through the mirror, so that the skin elasticity state can be easily confirmed. Furthermore, the skin elasticity notification unit 43 can be configured by sound generation means such as a buzzer appealing to the sense of hearing, or vibration means such as a vibrator appealing to the sense of touch besides the light emitting means appealing to the user's vision. The skin elasticity notification unit 43 may be configured by two or more of these means.

  The auxiliary application stored in the smartphone 5 includes a skin elasticity display unit that causes the display 52 to display the size of the skin elasticity measured by the skin elasticity sensor 40. The skin elasticity display 88 by the skin elasticity display means consists of three bars arranged in a straight line, and each bar corresponds to "small", "medium" and "large" sequentially from the left. When the information on the size of the skin elasticity is transmitted from the control unit 25 of the electric razor 1 to the smartphone 5 through the communication interface 24/64, the skin elasticity display means is a skin elasticity display 88 among the three bars, Control is performed to blink only the bar corresponding to the size. At this time, the remaining two bars may be always on or all off. In addition to this, the skin elasticity display 88 may be configured by, for example, three bars that are constantly lit, and an arrow pointing to any one of the bars.

  In general, skin elasticity varies from face to face. When the functional part 12 of the electric razor 1 is pressed in a portion where the skin elasticity is small, it is easy for the face skin to enter the hole of the outer blade 13 and the entering portion is strongly rubbed by the inner blade 14 and may be greatly damaged. Because of this, it is preferable to press the function part 12 with a relatively weak force. On the other hand, in the portion where the skin elasticity is large, even if the function part 12 is relatively strongly pressed, the face skin does not easily enter the hole of the outer blade 13. As in the present embodiment, when the skin elasticity measured by the skin elasticity sensor 40 is displayed on the display 52, the user is notified in real time of the skin elasticity of the part facing the functional part 12 and the pressing force of the functional part 12 on the relevant part Promote the appropriateness of

  Furthermore, the control unit 25 of the electric razor 1 automatically controls the number of rotations of the motor 16 according to the skin elasticity measured by the skin elasticity sensor 40. Specifically, control is performed to lower the rotational speed of the motor 16 as the measurement value of the skin elasticity sensor 40 is smaller. In the present embodiment, the number of rotations when the skin elasticity is "large" is set to 6500 rpm, which is the normal number of rotations, and the number of rotations when the skin elasticity is "medium" is set to 6300 rpm, which is a slight decrease. The rotational speed when the skin elasticity is "small" was set to the decelerating rotational speed of 6000 rpm.

  When the rotational speed of the motor 16 is automatically controlled in accordance with the measurement value of the skin elasticity sensor 40, the user changes the height of the drive sound of the motor 16 in addition to the skin elasticity notification unit 43 and the skin elasticity display 88 described above. Based on it, you can also know the size of your own skin elasticity. Further, in the present embodiment, the rotational speed of the motor 16 is lowered in consideration of the fact that the facial skin easily enters the hole of the outer blade 13 when the functional part 12 is pressed as the skin elasticity is smaller. It is possible to reduce the damage that the face skin having entered the hole receives from the outer cutter 13 and the inner cutter 14. Moreover, since the number of rotations of the motor 16 is automatically controlled, the user does not have to change the number of rotations. The other parts are the same as those of the interlocking system according to the first embodiment, so the same reference numerals are given to the same members and the description thereof will be omitted.
