A communication interface 64 that operates according to the standard of the above, and a control unit 65 that controls the entire smartphone 5 including these are mounted.

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

Further, the memory 61 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 manufacturer of the electric razor 1, and can be downloaded to the smartphone 5 from the server operated by the manufacturer via the Internet. The auxiliary application includes a mirroring means for making the display 52 usable as a mirror, a moving image resting means for stopping the moving image displayed on the display 52, and a lighting controlling means for controlling the lighting state of the LED 56. The auxiliary application also instructs the user to turn the smartphone 5 upside down, a zoom control means for controlling the zoom function of the camera 53, an illustration addition means for adding an auxiliary illustration 70 (see FIG. 10) to the face area displayed on the display 52. It is provided with a reversing instruction means for Further, the auxiliary application includes a device status notification means for displaying the device status of the electric razor 1 on the display 52, an electric device control means for transmitting a control signal for controlling the electric razor 1 to the control unit 25, and electricity on the display 52. It is provided with an instruction manual display means for displaying the instruction manual of the razor 1. This auxiliary application is a resident 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, starts shooting by the camera 53, and displays a moving image shot by the camera 53 on the display 52. During the execution of the camera program, the user's face facing the front surface 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 operating at the same time as the auxiliary application is started.

(Video resting means)
The moving image resting means stops the moving image displayed on the display 52 according to the user's operation while the mirroring means is operating. Specifically, when the user turns off the drive switch 21 while driving the electric razor 1, the moving image resting means stops the moving image displayed on the display 52, and when the user turns on the driving switch 21 again, the moving image stopping means changes. Release the still state of the video. The operation of the drive switch 21 is transmitted from the control unit 25 of the electric razor 1 to the smartphone 5 via the communication interfaces 24 and 64. The user operates the drive switch 21 to stop the moving image while the part of the face to be checked is projected on the camera 53, and moves the stationary display 52 to a position where it is easy to see, such as the front of the face. , The relevant part can be easily checked.

(Lighting control means)
The lighting control means controls to light the LED 56 of the smartphone 5 in a state where the connection between the electric razor 1 and the smartphone 5 is established. The LED 56 has a plurality of lighting patterns. In this embodiment, the LED 56 is lit with the first lighting pattern when the electric razor 1 is driven (a state in which a moving image is displayed on the display 52), and when the electric razor 1 is stopped (a state in which a moving image is displayed on the display 52). The LED 56 is lit in the second lighting pattern in the stationary state of the moving image of the display 52). Further, in this embodiment, the first lighting pattern is always lit and the second lighting pattern is blinking in the same color. In addition to this, for example, both lighting patterns are always lit and their color tone (emission color). ) May be different. In this embodiment, since the camera 53 and the LED 56 are arranged on the same side (front 51) of the smartphone 5, when the electric razor 1 and the smartphone 5 are used in a dim place, the image target of the camera 53, that is, the user's face is the LED 56. Can be illuminated with. Therefore, regardless of the brightness of the place where the electric razor 1 and the smartphone 5 are used, the user's face can always be clearly projected on the display 52 to improve the convenience of the user. The lighting device 56 in the present invention is not limited to the one built in the smartphone 5 as in the present embodiment, but also includes the one externally attached to the smartphone 5 and controlled by the auxiliary application.

As shown in the flowchart of FIG. 3, when the user turns on the drive switch 21 and turns 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 razor 1 becomes effective (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 thereof is also enabled. In addition, the 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 this push notification corresponds to the activation of the auxiliary application in the present invention (step S3). By tapping this push notification, the user can move 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 operating, and the moving image captured by the camera 53 is displayed on the display 52 (step S4). Further, the lighting control means lights the LED 56 in the first lighting pattern (step S5).

When the mirroring means starts operating, the moving image resting means enters the 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 image resting means stops the moving image displayed on the display 52 (step S7), and the lighting 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 restarted (YES in step S9), the moving image resting means releases the moving image resting state (step S10), and the lighting control means sets the LED 56 to the first lighting pattern. Switching (step S5), waiting for the drive switch 21 to be turned off again in step S6.

The control unit 25 of the electric razor 1 continues to enable the communication interface 24 immediately after the drive switch 21 is turned off, and communicates when a predetermined time (10 minutes in this embodiment) has elapsed from the off operation. Disable interface 24. However, the control unit 25 has a timer function for stopping the motor 16 when the continuous driving time of the motor 16 exceeds a predetermined time (5 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 time shorter than the predetermined time (5 minutes in this embodiment) elapses from the time of the stop.

The smartphone 5 stores a protection program that turns off the display 52 when it is considered that the user has left the smartphone 5 for a long time. If the above-mentioned video still means is operating for a long time while the auxiliary application is being executed, that is, if the video shown on the display 52 is still for a long time, the user finishes shaving and the electric razor 1 It is possible that the smartphone 5 was left unattended without turning off the display 52 after the display 52 was stopped.

On the other hand, when the moving image resting means is not operating and the moving image is displayed on the display 52, that is, in the mirrored state of the display 52, the user uses the smartphone 5 like a hand mirror and whiskers with the electric razor 1. Most likely you are shaving. However, even in the mirrored state, if the user's face or the electric razor 1 is not reflected on the camera 53 for a long time, the user may have left the smartphone 5 together with the driven electric razor 1. In these cases, the protection program turns off the display 52 to avoid wasteful consumption of the battery pack.

The specific control procedure by the protection program is shown in the flowchart of FIG. The protection program starts timing by a timer when the auxiliary application is started in the foreground (at this point, the mirroring means is operating and the moving image resting means is not operating) (step S11). In the subsequent protection program, a predetermined time (5 minutes in this embodiment) has passed since the start of timekeeping, the moving image resting means is operated and the display 52 is stopped, or the user's face is measured by the camera 53. Alternatively, it waits for the electric razor 1 to be detected (steps S12 to S14).

If the user's face or electric razor 1 is detected in the moving image displayed 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. Therefore, the process returns to step S11, the timer is reset, and the time counting is started again. On the other hand, if the user's face or the electric razor 1 is not detected and the display 52 does not stand still and a predetermined time elapses (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 unattended together with the electric razor 1, the protection program proceeds to step S15 and turns off the display 52.

If the moving image resting means operates and the display 52 comes to rest (YES in step S13), the process proceeds to step S16, the timer is reset, and the time counting is started again. If a predetermined time (5 minutes in this embodiment) has elapsed since the start of timekeeping before the rest state is released (NO in step S18, YES in step S17), the user finishes shaving and electricity. Since it is assumed that the smartphone 5 is left unattended without turning off the display 52 after stopping the razor 1, the protection program proceeds to step S15 to turn off the display 52. On the other hand, if the stationary state is released before the predetermined time elapses (NO in step S17, YES in step S18), the process returns to step S11 to reset the timer and start timing again. In addition to 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 linked. When the drive switch 21 is turned on at the time point t1, the motor 16 is activated in the electric razor 1 and the communication interface 24 is activated. At the same time, on the smartphone 5, an auxiliary application that stands by in the background displays a push notification on the display 52. Then, after a tap operation by the user, the auxiliary application is started in the foreground, and the display 52 is mirrored by the mirroring means. 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 to stop the motor 16 of the electric razor 1. At the same time, in the smartphone 5, the moving image displayed on the display 52 is stationary, and the LED 56 switches to the second lighting pattern.

At the next time point t3 (t3-t2 <5 minutes), the drive switch 21 is turned on to restart the motor 16 of the electric razor 1. At the same time, in the smartphone 5, the stationary state of the moving image by the moving image resting 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 stationary, and the LED 56 is the second. Switch to the lighting pattern. At the next time point t5 (t5-t4 = 5 minutes), the display 52 is turned off by the protection program described above. At the next time point t6 (t6-t4 = 10 minutes), the communication interface 24 of the electric razor 1 is invalidated. Further, in the smartphone 5, the auxiliary application automatically shifts to the standby state in the background and the LED 56 is turned off in response to the disconnection from the electric razor 1. The timing of turning off the LED 56 may be t5 when the display 52 is turned off.

The timing chart of FIG. 6 shows a case where the electric razor 1 is left in the driving state together with the smartphone 5 running the auxiliary application. The time t12 when the electric razor 1 and the smartphone 5 are left is set to be several minutes (2 to 3 minutes) after the time t11 when the drive switch 21 is turned on. In the electric razor 1, the motor 16 automatically stops at the time point t13 5 minutes after the on operation of the drive switch 21 (time point t11), and the communication interface 24 is invalidated at the time point t15 5 minutes after the time point t13. Be made. In the smartphone 5, the camera 53 cannot detect the user's face or the electric razor 1 after the time t12 left unattended by the user. Therefore, at the time t14 5 minutes after the time t12, the display 52 is set by the above-mentioned protection program. It is turned off. Further, at the time t15 when the connection with the electric razor 1 is cut off, the auxiliary application automatically shifts to the standby state in the background, and the LED 56 is turned off. If the camera 53 detects the user's face or the electric razor 1 before reaching the time point t14, that is, before 5 minutes have elapsed from the time point 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 the time t13 when 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 standby state in the background, and the timing at which the LED 56 is turned off may also be the time point t13.

The timing chart of FIG. 7 shows another control method by the auxiliary application and the protection program of the smartphone 5. The period from t21 when the drive switch 21 is turned on to t22 when the camera 53 cannot detect the user's face or the electric razor 1 is the same as the time t11 to t12 in FIG. At time t23, one minute after, the protection program turns off the display 52, and the electric device control means (detailed later) of the auxiliary application sends a control signal for decelerating the motor 16 to the control unit 25 of the electric razor 1. Send to. Then, at the time point t24, which is one minute after the time point t23, the motor 16 stops at the electric razor 1, the communication interface 24 becomes invalid, the auxiliary application shifts to the standby state in the background on the smartphone 5, and the LED 56 turns off. To do. If the camera 53 detects the user's face or the electric razor 1 before reaching the time point t23, that is, before one minute has elapsed from the time point t22, the timer for turning off the display 52 is reset. Further, instead of decelerating the motor 16 at the time point t23, the motor 16 may be stopped. In that case, the communication interface 24 is disabled, the auxiliary application is shifted to the standby state, and the LED 56 is turned off at the time point t23. Can be done.

The operation for controlling the moving image resting means is not limited to the switch operation of the electric razor 1 described above, and may be, for example, a tap operation of the display 52 of the smartphone 5 by the user, or the user may use the electric razor 1 or the smartphone. It may be a specific movement operation such as shaking 5. These movement operations are detected by the acceleration sensors 22 and 62 and the gyro sensors 23 and 63 built 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 interfaces 24 and 64.

(Zoom control means)
The zoom control means controls the zoom function of the camera 53 in conjunction with the movement 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 content thereof is transmitted from the control unit 25 to the smartphone 5 via the communication interfaces 24 and 64. The zoom control means controls the zoom function of the camera 53 based on the content 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 faces, so zoom. The control means zooms out the camera 53 and displays a wide area of the face on the display 52. Conversely, if the electric razor 1 is moving with a relatively small stroke, or if the electric razor 1 is moving relatively slowly, it is assumed that the user is shaving a part of the face intensively. Therefore, the zoom control means zooms in on the camera 53 and enlarges and projects a part of the face on the display 52.

It is also possible to analyze the moving image captured by the camera 53 and detect the movement operation of the electric razor 1 by the user. In order to facilitate this detection, a plurality of marks 28 that can be identified in the moving image are provided on the outer surface of the electric razor 1 (see FIG. 8). The marks 28 are mainly distributed around the functional unit 12, and a part of the marks 28 is always reflected 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 moving stroke and moving speed of the electric razor 1 can be detected, and the zoom function can be controlled in the same manner as before based on their sizes.

Further, as shown in FIG. 8, when the face recognition function of the camera program is also used, the functional unit 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 facing the face. 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 the two marks 28 around the functional unit 12 in the face area. When the functional unit 12 is located under the nose, the zoom control means zooms in on the camera 53, for example, and enlarges the area under the nose on the display 52. This is because it is rare to shave under the nose and other areas at the same time, and when shaving under the nose, one often concentrates on this.

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 content 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 in front of the face to display the entire face. Since it is assumed that the image is projected on the 52, the zoom control means zooms out the camera 53. On the contrary, as shown in FIG. 9B, when the front surface 51 of the smartphone 5 is about 45 ° with respect to the horizontal plane, the user moves the smartphone 5 diagonally below the face to cover the face such as the chin. Since it is assumed that only a part of the display 52 is to be projected, the zoom control means zooms in on the camera 53. Further, when the sensors 62 and 63 detect that the user has performed a specific movement operation such as shaking the smartphone 5, the zoom magnification of the camera 53 may be changed.

It is also possible to detect the movement operation of the smartphone 5 by 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 on the camera 53, for example, and displays 52. A 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 has moved the smartphone 5 away from the face. In this case, the zoom control means zooms out the camera 53, for example, to cover a wider area of the face. It is projected on the display 52. Further, the zoom function of the camera 53 may be controlled according to the facial expression of the face region in the moving image. For example, when the face area is recognized as a smiling face, the zoom control means zooms in on the camera 53, and when the face area is recognized as an angry face, the zoom control means zooms out the camera 53. Let me.

The above zoom control means may start the operation at the same time as the auxiliary application is started, or may start the operation according to the user's request after the auxiliary application is started. The operation for controlling the zoom control means is not limited to the above-mentioned movement operation of the electric razor 1 and the smartphone 5, and for example, the zoom function of the camera 53 is performed in conjunction with the switch operation on the side of the electric razor 1. Can be controlled. An example of the switch is a control switch for the rotation speed of the motor 16 provided on the electric razor 1. For example, when an operation for lowering the rotation speed is performed, the user carefully removes the whiskers of a part of the face. Since it is assumed that the camera is shaving, the zoom control means zooms in on the camera 53. The zoom function of the camera 53 can also be controlled by the user by directly operating the display 52 of the smartphone 5 and the buttons on the side surface.

(Illustration addition means)
As shown in FIG. 10, the illustration adding means adds the auxiliary illustration 70 to the face area displayed on the display 52 of the smartphone 5. The auxiliary illustration 70 according to the present embodiment is composed of an unprocessed illustration 71 showing an exaggerated whiskers and a processed illustration 72 showing that the whiskers have been shaved. When the illustration addition means starts the operation, the unprocessed illustration 71 is added to the area under the nose, chin, both cheeks, and sideburns of the face area detected by the face recognition function, and the user has completed shaving of each part. If it is determined, the unprocessed illustration 71 of that part is changed to the processed illustration 72. When all the unprocessed illustrations 71 on the display 52 are changed to the processed illustrations 72, the user can confirm that all the beards have been shaved (there is no unshaved part).

The completion of shaving of each part of the face is detected by using the mark 28 on the outer surface of the electric razor 1. As described earlier in the item of 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 part of the face facing the functional unit 12 of the electric razor 1 can be detected. .. When the number of times the functional unit 12 faces a part of the face, that is, passes through the face reaches a predetermined number of times, the illustration adding means determines that the shaving of the part is completed and changes the unprocessed illustration 71 to the processed illustration 72. To do.

The illustration adding means may start the operation at the same time as the auxiliary application is started, or may start the operation according to the user's request after the auxiliary application is started. Further, the auxiliary illustration 70 may be composed of only one of the unprocessed illustration 71 and the processed illustration 72. For example, when the auxiliary illustration 70 is composed of only the unprocessed illustration 71, the illustration adding means completes shaving. The unprocessed illustration 71 is deleted in order from the portion determined to have been used. The user can confirm that all the beards have been shaved when all the raw illustrations 71 disappear from the display 52. Further, the auxiliary illustration 70 can include an illustration during processing indicating that the process is in progress. For example, the auxiliary illustration 70 is assumed to include a plurality of types of processing illustrations in which the whiskers are gradually thinner than the unprocessed illustration 71, and each time the functional part 12 of the electric razor 1 passes through a part of the face, the part thereof. The auxiliary illustration 70 of the above can be changed to an illustration during processing with a thin beard.

(Reversal instruction means)
The flip instruction means instructs the user who uses the auxiliary application with the smartphone 5 in the normal posture to flip the smartphone 5 upside down. As shown in FIG. 1, the normal posture is a posture in which the camera 53 and the LED 56 are located on the upper part of the smartphone 5. When the smartphone 5 is turned upside down and turned upside down, the camera 53 is located at the lower part of the smartphone 5, so that it becomes easier to take a picture of the lower part of the face with a beard, particularly the submandibular part. It should be noted that the built-in gyro sensor 63 detects that the smartphone 5 is in the normal posture or the inverted posture.

For example, as shown in FIG. 11A, when the smartphone 5 is in the normal posture, an inverted character upside down can be displayed on the display 52, and this can be used as an inverted instruction means. When the user who sees the inverted characters intuitively flips the smartphone 5 upside down, as shown in FIG. 11B, the display 52 displays the normal characters in the correct orientation. Since the normal characters in FIG. 11B may be an obstacle when the user's face is projected on the display 52, they may disappear after a lapse of time or may be omitted.

Further, as shown in FIG. 12A, when the smartphone 5 is in the normal posture, characters such as "Please flip" are displayed on the display 52 to directly instruct the user to flip the smartphone 5 upside down. However, this can be used as a reversal instruction means. When the user flips the smartphone 5 upside down according to this character, as shown in FIG. 12B, a character indicating that the posture of the smartphone 5 is appropriate is displayed on the display 52, and this character is shown in FIG. 11 (b). For the same reason as the normal characters in b), they may disappear over time or may be omitted. In addition, instead of the character of FIG. 12A, a symbol such as a U-shaped arrow may be displayed and this may be used as the inversion instruction means.

Further, as shown in FIG. 13A, when the smartphone 5 is in the normal posture, the entire moving image displayed on the display 52 can be turned upside down and used as the inversion instruction means. When the user who sees his / her face turned upside down intuitively turns the smartphone 5 upside down, a moving image in the correct orientation is displayed on the display 52 as shown in FIG. 13B. Here, as in FIG. 12B, characters indicating that the posture of the smartphone 5 is appropriate may be displayed.

(Device status notification means)
As shown in FIG. 14, the device status notification means causes the display 52 to display the device status such as the remaining battery level of the electric razor 1. 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 blade 13 and the inner blade 14, and a functional unit 12 including a hair dust storage chamber. It is composed of a cleaning display 77 indicating the cleaning time of the electric razor, a load display 78 indicating the magnitude of the load acting on the functional unit 12, a time display 79 indicating the continuous use time of the electric razor 1, and the like. The device status notification means starts the operation at the same time as the auxiliary application is started, but can be stopped according to the subsequent user operation.

The battery remaining amount display 75 includes a numerical value indicating the remaining amount of the secondary battery 18 and five upper and lower scales, and the color tone changes from green to yellow to red as the remaining battery level 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 interfaces 24 and 64. When the remaining battery level falls below a predetermined ratio (for example, 20%), the device status notification means changes the color tone of the battery level display 75 to red, drives the vibrator 59 of the smartphone 5, and further sets the LED 56 in an emergency. It lights up in a pattern to notify the user that the battery level is low.

The replacement display 76 does not light when the blades 13 and 14 do not need to be replaced, but lights when the replacement time approaches. The control unit 25 of the electric razor 1 manages the cumulative usage time of the outer blade 13 and the inner blade 14 since the previous replacement, and when the cumulative usage time reaches a predetermined time, the blades 13 and 14 The fact that the replacement time is approaching is transmitted to the smartphone 5. In response to this, the device status notification means lights the display 52 with the replacement display 76 for the blades 13 and 14 whose replacement time is approaching, drives the vibrator 59, and lights the LED 56 in an emergency pattern. Encourage the user to replace the blades 13 and 14. After the user replaces the blades 13 and 14, for example, when the replacement display 76 on the display 52 is pressed and held, the device status notification means considers that the replacement of the blades 13 and 14 is completed, turns off the replacement display 76, and turns off the replacement display 76. The fact that the replacement of the blades 13 and 14 is completed is transmitted to the control unit 25 of the electric razor 1. Upon receiving this, the control unit 25 resets the cumulative usage time of the replaced blades 13 and 14. The fact that the blades 13 and 14 are about to be replaced may be determined based on the number of times the drive switch 21 is turned on and off, in addition to the cumulative usage time.

The cleaning display 77 does not light up when the functional unit 12 does not need to be cleaned, but lights up when the cleaning time approaches. An optical sensor for detecting the accumulation of hair is provided in the hair dust storage chamber constituting the functional unit 12, and when the accumulation of hair exceeds a predetermined reference value, the control unit 25 is cleaned. The time is approaching is transmitted to the smartphone 5. Upon receiving this, the device status notification means lights the cleaning display 77 on the display 52, drives the vibrator 59, and lights the LED 56 in an emergency pattern to prompt the user to clean the functional unit 12. When the user performs cleaning and the amount of accumulated hair becomes less than a predetermined value, the control unit 25 transmits to the smartphone 5 that the cleaning is completed, and the device status notification means that receives the cleaning turns off the cleaning display 77. .. It should be noted that the approaching cleaning time of the functional unit 12 may be determined based on the cumulative usage time since the previous cleaning and the number of times the drive switch 21 is turned on and off, in addition to the degree of accumulation of hair dust.

The load display 78 displays the magnitude of the load acting on the functional unit 12 of the electric razor 1 to encourage the user to adjust the strength of the force for pressing the functional unit 12 against the facial 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 greater the load. Therefore, when the magnitude of the load of the functional unit 12 is displayed on the display 52, the strength of the pressing force at that time can be notified to the user. By shaving while checking the load display 78, the user can always maintain the pressing force of the functional unit 12 at an appropriate strength and reduce the burden on the facial skin.

The load current flowing through the motor 16 is used as an index of the load magnitude of the functional unit 12. As the load of the functional 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 includes a superior arc-shaped scale indicating the magnitude of the load and an indicator needle indicating one point on the scale, and indicates that the load is small (the pressing force is weak) from the lower left to the lower right of the scale. A low load zone (green), a medium load zone (blue) indicating that the load (pressing force) is moderate, a high load zone (green) indicating that the load is large (strong pressing force), and a load (green). 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 indicator needle always points to the medium load zone. When the indicator needle of the load display 78 points to the overload zone, the device status notification means drives the vibrator 59 and further lights the LED 56 in an emergency pattern to alert the user.

When the user taps 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 includes two concentrically arranged superior arc-shaped scales and an arrow pointing to one point on 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 this information is transmitted from the control unit 25 of the electric razor 1 to the smartphone 5. When the rotation speed of the motor 16 falls below a predetermined lower limit value, or when the load torque exceeds a predetermined upper limit value, the device state notification means considers that the load applied to the functional unit 12 is excessive and the vibrator. The 59 is driven, and the LED 56 is turned on in an emergency pattern to alert the user. When the user taps 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 of the electric razor 1 once, 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. Even when the motor 16 is stopped by the timer function after a predetermined time (5 minutes) has elapsed from the on operation of the drive switch 21, the continuous use time is similarly reset. The device status notification means changes the time display 79 to, for example, red, drives the vibrator 59, and lights the LED 56 in an emergency pattern, for example, one minute before the motor 16 is stopped by the timer function. Call the user's attention. This 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 that the continuous use time can be measured on the smartphone 5 side as well.

(Electrical equipment control means)
The electric device control means transmits a control signal for controlling the electric razor 1 to the control unit 25 via the communication interfaces 24 and 64. At the left end of the display 52, a rotation speed lever 81 for changing the rotation speed of the motor 16 of the electric razor 1, a drive button 82 for turning the motor 16 on and off, and the above-mentioned A lock button 83 for locking the motor 16 to the driving state is arranged regardless of the timer function of the above.

When the user slides the rotation 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 razor 1 via the communication interfaces 24 and 64. .. When the user taps the drive button 82 in the stopped state of the motor 16, the electric device control means transmits a control signal for starting the motor 16 to the control unit 25. Further, when the user taps the drive button 82 in the drive 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 transmitted to the control unit 25. When the motor 16 is locked in the driving state, even if the user carelessly touches the switch button 15, the motor 16 does not stop against the intention of the user.

In addition to the above, the electric device control means can control the electric razor 1 according to 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 for accelerating the motor 16 to the control unit 25, and when the user tilts the smartphone 5 to the left or right, the electric device is controlled. The means transmits a control signal for decelerating the motor 16 to the control unit 25. 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.

Further, in the electric device control means, for example, when the functional unit 12 of the electric razor 1 faces under the nose of the user's face, the motor 16 is slowed down, and the motor 16 is adjusted according to the part of the face that the functional unit 12 faces. It is possible to control the number of rotations of. As described earlier in the item of 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 part of the face facing the functional unit 12 can be detected. Further, as described in the timing chart of FIG. 7, the electric device control means is a motor 16 even if the user does not operate the smartphone 5 when it is considered that the user has left the electric razor 1 or the smartphone 5 unattended. A control signal for decelerating or stopping the smartphone can be transmitted to the control unit 25.

(Instruction manual display means)
The instruction manual 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 manual button 85 (see FIG. 14) on the display 52, the manual display means switches the display 52 from the mirror display to the manual display shown in FIG. A mirror button 86 is arranged at a corner of the display 52 in the instruction manual display, and when the user taps the mirror button 86, the instruction manual display means switches the display 52 from the instruction manual display to the mirror display.

The instruction manual in this embodiment is composed of a plurality of pages such as "table of contents", "names and functions of each part", "how to use", "blade replacement", and "blade cleaning". Immediately after the display 52 switches to the instruction manual display, the table of contents is displayed, so the user can tap the link to each page included in the table of contents or slide the display 52 left or right to select the desired page. It can be displayed on the display 52, and the page can be reduced by a pinch-in operation and enlarged by a pinch-out operation. In addition to the instruction manual button 85 of this embodiment, or in addition to the instruction manual button 85, a plurality of buttons such as "how to use", "blade replacement", and "blade cleaning" 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 the auxiliary application in advance, or may be downloaded from the server of the manufacturer of the electric razor 1 via the Internet when the instruction manual button 85 is tapped.

In the flowchart of FIG. 17, the display 52 is a mirror display immediately after the auxiliary application is activated on the smartphone 5. When the instruction manual button 85 on the display 52 is tapped (YES in step S21), the instruction manual display means switches the display 52 from the mirror display to the instruction manual display (step S22). At the same time, the control unit 25 stops the motor 16 according to the control signal transmitted from the electric device control means to the electric razor 1 (step S23). After that, it 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 razor 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 interfaces 24 and 64, and the manual display means that receives this switches the display 52 from the manual display to the mirror display. .. When the mirror button 86 on the display 52 is tapped (YES in step S25), the process proceeds to step S26, and the manual display means switches the display 52 to the mirror display. At the same time, the control unit 25 activates the motor 16 according to the control signal transmitted from the electric device control means to the electric razor 1.

The timing chart of FIG. 18 shows an example when the display 52 and the motor 16 are controlled according to the flowchart of FIG. At the time point t31, the instruction manual button 85 is tapped to switch the display 52 from the mirror display to the instruction manual display, and at the electric razor 1, the motor 16 is stopped. At the next time point t32, the mirror button 86 is tapped to switch the display 52 to the mirror display, and the motor 16 is activated. At the next time point t33, the instruction manual button 85 is tapped as in the time point t31, the display 52 is switched to the instruction manual display, and the motor 16 is stopped.

(Example 2) FIG. 19 shows Example 2 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 means) 40 is provided between the two functional units 12. The functional unit 12 includes an outer blade (cutting blade) 13 and an inner blade (cutting blade) 14. As the skin elasticity sensor 40, various conventionally known sensors can be used. For example, the oscillator sensor disclosed in JP-A-2009-153727 and the feeling disclosed in JP-A-61-181437. A pressure sensor can be mentioned. The skin elasticity sensor 40 according to the present embodiment includes a contactor 41 that comes into contact with the skin surface at the same time as the outer blade 13, and a spring 42 that urges 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 portion 12 in the case body constituting the razor head 11 as long as it can come into contact with the skin surface at the same time as the functional portion 12.

On the side of the main body case 10, a skin elasticity notification unit 43 that displays the magnitude of skin elasticity in three stages of "small", "medium", and "large" is provided. The skin elasticity notification unit 43 is composed of three LEDs mounted on the control board 17, and these LEDs correspond to "small", "medium", and "large", respectively. The main body case 10 is provided with a translucent window facing each LED, and the user can visually recognize the light emitting state of each LED through the translucent window. The control unit 25 of the electric razor 1 controls to turn on any one LED of the skin elasticity notification unit 43 according to the magnitude 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. In this case, the skin elasticity notification unit 43 is composed 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 skin elasticity. The color can be changed to "red" to notify the user of skin elasticity. If the razor head 11 is provided with the skin elasticity notification unit 43 in this way, it is easy for the user to visually recognize the light emitting state and to confirm the skin elasticity state. The skin elasticity notification unit 43 that displays light emission and is arranged on the main body case 10 side may be hidden by the hand of the user who holds the main body case 10, but there is a possibility that it is arranged on the razor head 11. Few. When the electric razor 1 is used, the back surface thereof is mainly reflected in the mirror, so it is preferable to provide the skin elasticity notification unit 43 on the back surface (rear surface) of the razor head 11. Alternatively, it is preferable that the skin elasticity notification unit 43 is provided inside the razor head 11 and the light is irradiated through the transparent portion (including the translucent portion) of the case body or the outer blade 13 constituting the razor head 11. According to these configurations, the user can easily see the light emitted by the skin elasticity notification unit 43 through the mirror, so that the skin elasticity state can be easily confirmed. Further, the skin elasticity notification unit 43 can be configured by a sounding means such as a buzzer appealing to the auditory sense and a vibrating means such as a vibrator appealing to the sense of touch, in addition to the light emitting means appealing to the user's vision. Of these, the skin elasticity notification unit 43 may be configured by two or more means.

The auxiliary application stored in the smartphone 5 includes a skin elasticity display means for displaying the magnitude of the skin elasticity measured by the skin elasticity sensor 40 on the display 52. 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" in order from the left. When the information on the magnitude of the skin elasticity is transmitted from the control unit 25 of the electric razor 1 to the smartphone 5 via the communication interfaces 24 and 64, the skin elasticity display means is among the three bars of the skin elasticity display 88. Control is performed to blink only the bar corresponding to the size. At this time, the remaining two bars may be constantly lit or constantly turned off. In addition to this, the skin elasticity display 88 may be composed of, for example, three bars that are always lit and an arrow pointing to any one of the bars.

In general, skin elasticity varies from face to face. In the part where the skin elasticity is small, when the functional part 12 of the electric razor 1 is pressed, the facial skin easily gets into the hole of the outer blade 13, and the part that has entered may be strongly rubbed by the inner blade 14 and suffer great damage. Therefore, it is preferable to press the functional unit 12 with a relatively weak force. On the other hand, in the portion having large skin elasticity, even if the functional portion 12 is pressed relatively strongly, the facial skin does not easily enter the hole of the outer blade 13. When the skin elasticity measured by the skin elasticity sensor 40 is displayed on the display 52 as in the present embodiment, the user is notified in real time of the skin elasticity of the portion facing the functional unit 12, and the pressing force of the functional unit 12 against the portion is notified. It is possible to promote the optimization of.

Further, the control unit 25 of the electric razor 1 automatically controls the rotation speed of the motor 16 according to the skin elasticity measured by the skin elasticity sensor 40. Specifically, the smaller the measured value of the skin elasticity sensor 40, the lower the rotation speed of the motor 16. In this embodiment, the rotation speed when the skin elasticity is "large" is set to 6500 rpm, which is a normal rotation speed, and the rotation speed when the skin elasticity is "medium" is set to 6300 rpm, which is a slightly reduced rotation speed. , The rotation speed when the skin elasticity is "small" was set to 6000 rpm, which is the deceleration rotation speed.

When the rotation speed of the motor 16 is automatically controlled according to the measured value of the skin elasticity sensor 40, the user can change the pitch of the driving sound of the motor 16 in addition to the skin elasticity notification unit 43 and the skin elasticity display 88 described above. Based on this, you can also know the magnitude of your skin elasticity. Further, in this embodiment, the rotation speed of the motor 16 is lowered in consideration of the fact that the smaller the skin elasticity is, the easier it is for the facial skin to enter the hole of the outer blade 13 when the functional portion 12 is pressed. It is possible to reduce the damage that the facial skin that has entered the hole receives from the outer blade 13 and the inner blade 14. Moreover, since the rotation speed of the motor 16 is automatically controlled, the user does not have to take the trouble of changing the rotation speed.
