Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mirror device for displaying an arbitrary image such as a character, a numerical value or a picture on a mirror surface, and varying the display illuminance of the image in accordance with the presence or absence and brightness of a human body around the mirror device. The present invention relates to a mirror device and a vanity stand provided with the same.

[Prior art]

Conventionally, a utility model registration No. 3065 has been proposed as a mirror device for displaying an arbitrary image such as a character, a numerical value or a picture on a mirror surface.
No. 082 has been proposed. The mirror device 21 shown in the figure has a rear surface of a mirror provided with a transmissive portion so as to transmit visible light from inside to outside, and allows light to pass through a predetermined predetermined pass area and shields light outside the pass area. A mask sheet 23, an electroluminescence sheet 24 that outputs visible light by applying a predetermined voltage,
Are sequentially arranged in close contact with each other. On the entire back surface of the glass plate 11 serving as a mirror, a semi-transmissive metal film 22 is formed by depositing a metal such as silver and fixing the same by sputtering so that light transmits at a predetermined transmittance and functions as a mirror surface. Have been. The letters “A” and “B” are engraved on the mask sheet 23, and the portions are light passing areas. The electroluminescence sheet 24 is composed of a transparent electrode, an inorganic phosphor, an insulator, and an electrode, and its periphery is covered with a resin. When an AC driving voltage of about several hundred volts is applied between the transparent electrodes, the inorganic phosphor emits light, and the characters engraved on the mask sheet 23 are displayed on the mirror surface.

[0003]

However, since the above-mentioned mirror device is not provided with a means for controlling the voltage applied to the electroluminescence sheet 24 as the light emitting means, the mirror surface cannot be turned on when a person does not turn on the power or the switch. , A state in which nothing is displayed, and if not cut, a state in which images such as characters, numerical values, and pictures are always displayed on the mirror surface is maintained. For this reason, when a person uses a mirror to perform hairdressing or makeup, if a certain image is constantly displayed on the mirror surface, that part of the image will not be able to perform the function of the mirror sufficiently because the reflection will be reduced. Further, there is a possibility that waste of power due to forgetting to turn off the power supply or the like and loss of advertisement or advertising effect due to forgetting to turn on the power may occur. In particular, displaying an image for advertisement or advertisement on a mirror device in a place where no one is present has no effect and consumes power only wastefully.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem. In a mirror device for displaying an arbitrary image such as a character, a numerical value, and a picture on a mirror surface, the present invention is directed to the presence or absence and brightness of a human body around the mirror device. It is an object of the present invention to provide a mirror device for changing display illuminance of an image and a vanity table provided with the same.

[0005]

Means for Solving the Problems and Action / Effect In order to solve the above problems, the invention according to claim 1 is a mirror device for displaying an arbitrary image such as a character, a numerical value or a picture on a mirror surface. A display device that changes the display illuminance of an image according to the presence or absence of a human body located in front of and near the human body or the distance from the mirror device to the human body.
By changing the display illuminance of an image displayed on the mirror surface in accordance with the presence or absence of a human body located in front of and near the mirror device, for example, when a person is present in front of and near the mirror device, the mirror surface By displaying an image on the screen and reducing the display illuminance of the image when no person is present, waste of power required for image display is prevented. Then, when a person approaches the mirror device, the image is displayed unexpectedly on the mirror surface, so that the unexpected appearance (amazing) of the suddenly appearing image can make the human eyes gaze at the image. Since it can be used, it is effective to use it as an advertising means. Also, by changing the display illuminance of the image displayed on the mirror surface according to the distance from the mirror device to the human body, for example, when the distance from the mirror device to the human body is several meters or more, the display illuminance of the image is changed. Is increased, and the visibility of the image can be improved by lowering the display illuminance of the image so as not to be too dazzling when the human body is approaching about 1 m from the mirror device. Furthermore, when a person approaches within 1 m from the mirror device and stops for more than one second, the image may be hidden, and the mirror may function as a hairdresser or make-up. it can.

According to a second aspect of the present invention, in a mirror device for displaying an arbitrary image such as a character, a numerical value and a picture on a mirror surface, the display illuminance of the image is varied according to the brightness around the mirror device. It is a mirror device characterized by the following. By changing the display illuminance of the image displayed on the mirror surface according to the brightness around the mirror device, for example, when the mirror device is installed indoors and the room lighting is turned off at midnight or the like and dark, a person is present. By determining that the image is not to be displayed and maintaining the image in the non-display state, it is possible to prevent waste of power required for image display. Also, when the mirror device is installed outdoors, the image is displayed at an appropriate brightness by changing the display illuminance of the image according to the change in the brightness around the mirror device in the morning, daytime, night. In addition, constant visibility can always be ensured.

According to a third aspect of the present invention, there is provided a mirror means having a transmission portion for transmitting visible light from inside to outside, and light emission for applying a voltage to emit an arbitrary image such as a character, a numerical value, or a picture. Display means, light quantity control means for controlling the light quantity of the light emitting display means, and human body detection means for detecting the presence or absence of a human body located in front of and near the mirror means or for detecting the distance from the mirror device to the human body. The light-emitting display means is arranged behind the mirror unit at a transmission part, and the light-amount control unit controls the light amount of the light-emitting display unit in accordance with a signal from the human body detection unit, and the surface of the mirror unit is controlled. And a display device that changes display illuminance of an image displayed on the mirror device. An infrared sensor that emits sensor waves forward to detect the presence or absence of a human body, and a human body detection means such as a microphone that picks up human voices, walking sounds, and noises to detect the presence or absence of a human body, are placed around or near the mirror device. The light emission control means is arranged to transmit the detection signal to the light quantity control means to vary the voltage applied to the light emission display means to increase or decrease the light quantity of the light emission display means. As a result, it is possible to automatically switch the display illuminance of the image displayed on the surface of the mirror means, it is possible to display the image efficiently, and it is possible to prevent waste of power. For example, when a person is present in front of and near the mirror device, a predetermined voltage is applied to the light-emitting display means to display an image on the surface of the mirror means, and when no person is present, the light-emitting display means is applied. By reducing or lowering the voltage to reduce the display illuminance of the image, while preventing waste of power required for image display,
Premature deterioration of the light emitting display means can be prevented, and maintenance due to replacement can be reduced. Therefore, rather than providing an on / off switch for applying a voltage to the light emitting display means around the mirror device and displaying the image at all times, the image is displayed only when a person is present in front of and near the mirror device. Thus, the light-emitting display means is not forgotten to be turned off, power consumption is suppressed, and the economy is excellent. Furthermore, a distance measuring sensor or the like for detecting the distance from the mirror means to the human body is provided around or near the mirror device, and the light amount of the light emitting display means is increased or decreased according to the movement of the human body located in front of the mirror means. The display illuminance of the image displayed on the surface of the mirror means can be increased or decreased.

According to a fourth aspect of the present invention, there is provided a mirror means provided with a transmitting portion for transmitting visible light from inside to outside, and a light emitting device which emits light by applying a voltage and displays an arbitrary image such as a character, a numerical value or a picture. Display means, light quantity control means for controlling the light quantity of the light-emitting display means, and illuminance detection means for detecting the brightness around the mirror means, and the light source is located behind the transmission part of the mirror means. A light emitting display means is arranged, and the light quantity of the light emitting display means is controlled by the light quantity control means in accordance with a signal from the illuminance detecting means to change the display illuminance of an image displayed on the surface of the mirror means. Mirror device. An optical sensor for detecting the brightness around the mirror device is arranged above or around the mirror device, the detection signal is transmitted to the light amount control means, the voltage applied to the light emitting display means is changed, and the light amount of the light emitting display means is changed. Increase or decrease. As a result, it is possible to automatically switch the display illuminance of the image displayed on the surface of the mirror means, it is possible to efficiently display the image, and it is possible to prevent waste of power. For example, when the mirror device is installed indoors and the room lighting is turned off at midnight or the like and the room is dark, it is determined that there is no person, the application of the voltage to the light emitting display means is stopped, and the image is kept in a non-display state, When the mirror device is installed outdoors, by varying the voltage applied to the light emitting display means in accordance with the change in the brightness around the mirror device in the morning, daytime and night, the visibility is not reduced. An image is displayed on the surface of the mirror means by adjusting the light amount of the light emitting display means. Furthermore, by using the human body detecting means and the illuminance detecting means together, when the person is located in front of the mirror device and there is no lighting, it recognizes that the person does not look at the mirror device and sends a voltage to the light emitting display means. It can also be controlled not to apply.

The invention according to claim 5 is characterized in that the transmittance of the transmission portion provided in the mirror means is in the range of 10 to 50%. Mirror devices, such as general portable, stationary, and vanity tables, are manufactured by applying a metal material such as aluminum or silver with high reflectivity to a transparent glass plate to be the back of the mirror device by vacuum evaporation or sputtering. By fixing the film on the entire surface and increasing the film thickness, the transmittance is reduced and the reflectance is 93%.
About 98%. Then, by using sunlight, outdoor lighting, indoor lighting, and light sources such as light bulbs and fluorescent lamps that are specially arranged around the mirror device, light is radiated to the human body and the subject located in front of the mirror device and reflected. By making light incident on the surface of the mirror device, a human body or a subject located in front of the mirror device is brightly projected. When the mirror means has a half-mirror structure on the entire surface or a part of the mirror means as in the mirror device of the present invention, if the transmittance of the transmitting portion provided in the mirror means exceeds 50%, the human body or the human body is illuminated by a light source such as illumination. Even if the subject is sufficiently irradiated with light, the reflectivity of the mirror means is low, so that the human body and the subject projected on the mirror device become dim and do not function satisfactorily as a mirror function. If the transmittance is less than 10%, the light emitted from the light emitting display means is not efficiently transmitted to the surface of the mirror means, so that the visibility of the displayed image is reduced and the function as the image display function is sufficiently performed. I can't. Then, if an attempt is made to increase the illuminance of the light-emitting display means, replacement due to early deterioration of the light-emitting display means, increase in power consumption,
Economic efficiency decreases.

The invention according to claim 6 is characterized in that an image is displayed only around a substantially central portion of the mirror means in response to a signal from the human body detecting means. When a person is far away, an image is displayed using the entire surface of the mirror means, and when close, the light emission display range is set according to the distance from the mirror device to the human body. By switching, the priorities of the mirror function and the image display function are appropriately determined, and the image display function can be used effectively without giving the user a sense of discomfort. Also, if the transmittance of the mirror means is increased, the reflectance of light reflected from the human body or the subject and incident on the surface of the mirror device is reduced, and as a result, the light is reflected on the mirror surface as compared with a mirror having excellent reflectance. The human body becomes dark, which is unsuitable especially when brightness is required, such as when making up the face. Therefore, in the case of a mirror device which is arranged for the purpose of frequent makeup of the face, the reflectance at the substantially central portion of the mirror means is set to about 93 to 98% in advance, and only the periphery of the substantially central portion has a transmission structure, Preferably, an image is displayed on the light emitting display means. The substantially central portion referred to here is a region having a diameter of about 10 cm to 30 cm including at least the center point of the mirror device and having the same size as the face of a human body, and is preferably a region having a width of about 20 cm and a height of about 30 cm. Desirably.

According to a seventh aspect of the present invention, the light emitting display means includes:
It is characterized by using electroluminescence. As a light-emitting display means, a light-emitting means such as a cold-cathode tube or a fluorescent lamp is brought into close contact with a mask sheet from which an arbitrary image such as a character or a picture is cut out, and is arranged behind a mirror means provided with a transmission portion, thereby providing a mirror. Although an image can be displayed on the surface of the device, the use of electroluminescence (hereinafter, EL) as the light-emitting device can reduce the thickness of the mirror device. And the EL hardly generates heat when emitting light,
Since power can be efficiently converted to light energy, power consumption is low and economy is excellent. In particular, when it is desired to change the display image as needed or to display a fine image in a narrow display area with good visibility, the EL voltage of 3 to 15 V is higher than that of an EL made of an inorganic phosphor which emits light by high frequency driving with an alternating frequency. It is preferable to use an EL made of an organic phosphor that emits light at a low DC voltage from the viewpoint of safety and reliability. By arranging a plurality of organic phosphor elements densely in a matrix or segment and selectively lighting each element, it is possible to easily display fine images such as letters, numbers and pictures on the surface of the mirror means. And the occurrence of electric noise is small, and there is almost no adverse effect on peripheral devices.

According to an eighth aspect of the present invention, the light amount control means includes:
Has an inverter mechanism that varies the voltage or frequency,
It is characterized in that the light amount of the light emitting display means is controlled. Rather than directly applying the commercial power supply voltage to the light emitting means, the AC light source is once converted to direct current, the direct current is converted to a variable voltage / variable frequency alternating current and applied to the light emitting means. Light can be emitted efficiently. Therefore, when a person approaches the mirror device, an image can be quickly displayed on the surface of the mirror means. In addition, by varying the voltage and the frequency, the illuminance of the light emitting means can be precisely and easily adjusted, so that the controllability is excellent. For example, in the case of a mirror device in which an EL sheet made of an inorganic phosphor is provided behind the mirror means as a light emitting means, the voltage applied to the electrodes of the EL is kept constant, and the frequency is changed in the range of 50 to 10 kHz. As a result, the illuminance of the image displayed on the surface of the mirror means can be easily changed.

According to a ninth aspect of the present invention, there is provided a vanity table provided with the mirror device of the present invention. The mirror device provided in the vanity set up in the washroom or toilet space has many opportunities for people to look slowly, such as hairdressing and facial makeup, so by installing the mirror device of the present invention there, It is possible to display an image of an advertisement or advertisement without taking it, and the space can be effectively used. Printed materials such as paper are not suitable for being installed in a washroom or toilet space and left for a long period of time because they are vulnerable to moisture such as moisture.However, the light emitting display means provided on the back of the mirror means poor display due to deterioration. When it is installed in a public place without causing any problem, it is possible to prevent the advertisement from being hindered by doodles or theft. Also, when water is flowing from the faucet, such as when the user is concentrating on hand washing, etc., the user recognizes that he / she does not see the mirror device and reduces or stops the application of the voltage to the light emitting display means, and turns off the mirror. The display illuminance of the image displayed on the means can be adjusted.

According to a tenth aspect of the present invention, a terminal device
An image display control method characterized by transmitting display information to a mirror device of the present invention or a vanity stand provided with the same, and displaying an image on the surface of the mirror means according to the display information. By providing the light quantity control means with a microcomputer for processing display information transmitted from the terminal device and an information processing means constituted by an integrated circuit equivalent thereto, according to the display information transmitted from the terminal device to the mirror device, An image can be displayed on the surface of the mirror means. The information processing means includes a timer circuit, a reset circuit, an image conversion circuit for digitizing the transmitted image, and the like, and transmits the following information as display information from the terminal device to the mirror device, thereby displaying the information on the mirror means. The user can easily and freely operate the image to be displayed. In the case of a mirror device in which a predetermined single image is displayed on the mirror means, the following display time information. For example, 1 second O
N-1 second OFF, 3 second ON-1 second OFF, 1 second ON-3
Display at fixed intervals by repetition such as OFF for seconds, especially O
N-OFF time is not set and random display with irregular timing, display for a fixed time such as from 6:00 in the morning to 8:00 at night. In the case of a mirror device in which a plurality of predetermined images are displayed on the mirror means, display time information described and individual display time information in each image. In the case of a mirror device in which an arbitrary image is displayed on the mirror means,
Display time information described and display image information such as characters, numerical values, and patterns to be displayed. In addition, the display information transmitted from the terminal device can be erased by including the information storage unit including a memory circuit or the like capable of storing the display information in the light amount control unit and rewriting the information as necessary. This eliminates the need to constantly connect the terminal device to the mirror device. Display information from the terminal device is transmitted to the mirror device wirelessly or by wire, but in the case of a water surrounding space such as a toilet or a washroom, if the communication adapter or cable is exposed to the outside, malfunction due to water exposure, It is preferable to transmit the display information wirelessly because a failure may occur. Further, the information processing means and the information storage means may be provided in each mirror device. However, when transmitting display information to a plurality of mirror devices and controlling an image to be displayed, a plurality of mirror devices are required in consideration of manufacturing costs and arrangement space. It is preferable to share information processing means and information storage means with the mirror device.

[0015] The invention according to claim 11 is a mirror device or
An image display control method characterized in that in a space in which a plurality of vanity tables provided with the above are arranged, each mirror device is linked to display an image on the surface of each mirror means. A plurality of mirror devices arranged side by side on the same plane, such as a toilet space, are regarded as one light emitting display means, and necessary for linking an image displayed by each mirror means from the terminal device to each mirror device. By transmitting the display information, the display image or the display area can be enlarged, and the visibility from a distance is improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments of the mirror device according to the present invention will be described below in detail with reference to the drawings. In the drawings described in the present embodiment, the thickness of each member is different from the actual thickness for convenience of explanation. Mirror device 1 shown in FIG.
The light emitting display means 3 is disposed on the back of the mirror means 2, and the light emitting display means 3 is electrically connected to a light quantity control means 4 for controlling the light quantity. A distance measuring sensor 5 that projects a sensor wave in front of the mirror device 1 and detects whether a person is in front of the mirror device 1 and how far the person is off the mirror device 2 is located below the mirror device 2. Is provided with an optical sensor 6 for detecting the illuminance of the illumination, and a detection signal is transmitted from each sensor to the light amount control means 4. With such a configuration,
According to the presence or absence of a human body and the brightness around the mirror device, the light amount of the light emitting display means 3 can be efficiently controlled, and an image can be displayed on the surface of the mirror means.

Silver is deposited on the entire back surface of the glass plate serving as the mirror means 2 by a vacuum deposition method so that the reflectance is 80% and the transmittance is 20%. By adjusting the transmittance ratio in the range of 10 to 50% according to the use environment and situation, the mirror function does not give the user a sense of incongruity, and the mirror means displays images when displayed. Nature can be secured. In addition, it is possible to prevent an increase in power consumption of the light-emitting display means and to prevent the light-emitting display means from being replaced due to early deterioration, thereby improving economy and maintenance.

Further, in the case of a mirror means which frequently makes up the face, etc., a substantially central portion of the mirror means is used as the reflecting portion 13 to have a reflectance of 9%.
The transmittance is 1 to 3 to 98%, and the surrounding area is the transmission section 12.
It is preferable to display an image only around the substantially central portion of the mirror means 2 ′ by using a mirror means 2 ′ (shown in FIG. 2) on which silver is deposited so as to have a concentration of 0 to 50%. Further, by disposing the light emitting display means 3 on the back surface of the mirror means 2 'and thereafter covering the whole with a protective resin 14 having a waterproof property, the light emitting display means 3 can be installed in a place with high humidity such as a washroom. . As the mirror means, aluminum may be deposited on the back surface of the glass plate, silver may be deposited on the whole by several to several tens of nm, and a low-cost material such as copper may be laminated to adjust the transmittance. The effect of can be obtained.

The light emitting display means 3 arranged on the back of the mirror means 2 emits light by applying a voltage to a mask sheet in which an arbitrary image such as a character or a picture to be displayed on the surface of the mirror means 2 is cut out in advance. And an electroluminescent sheet using an inorganic phosphor. By using the electroluminescence sheet as the light emitting means, the power for displaying an image can be reduced, and the mirror device 1 can be made thinner. As the emission color of the inorganic phosphor, it is preferable to use white which is easy on human eyes.However, phosphors having different emission colors are laminated, and depending on the user's preference and the surrounding environment, generally a light bulb color is used. A slightly reddish warm color called a so-called fluorescent light color or a slightly bluish cool color called a fluorescent lamp color can also be selected. Also, an electroluminescent sheet in which organic phosphor elements emitting light at a low direct current voltage of 3 to 15 V are densely arranged in a matrix or a segment is arranged on the back surface of the mirror means 2, and each element is selectively turned on. Then, a fine image such as a character, a numeral, or a picture can be displayed in multiple colors on the surface of the mirror means 2. By disposing a heating means such as a sheet heating element on the back of the light emitting display means 3, the temperature of the mirror means 2 is prevented from lowering, and the mirror means 2 generated by the difference between the temperature of the mirror means 2 and its surrounding temperature. By preventing the surface from fogging, the visibility of the image displayed on the mirror unit 2 can be ensured.

The light quantity control means 4 connected to the light emission display means 3 comprises a converter circuit for converting AC into DC and an inverter circuit for converting DC into a variable voltage and a variable frequency, and is supplied from a commercial power supply or a battery. The voltage and frequency are efficiently converted and applied to the light emitting display means 3. Instead of directly applying the commercial power supply voltage to the light-emitting display means 3, the AC power supply is once converted to direct current, the direct current is converted into a variable voltage / variable frequency alternating current, and applied to the light-emitting display means 3, thereby providing a light-emitting display. The means 3 can emit light quickly and efficiently. Therefore, when a person approaches the mirror device 1 or when the periphery of the mirror device 1 becomes bright, an image can be quickly displayed on the surface of the mirror means 2. Further, by varying the voltage and the frequency, the illuminance of the light-emitting display means 3 can be adjusted precisely and easily, so that the controllability is excellent. The light quantity control means 4 has an inverter mechanism, converts the commercial power supply voltage, and supplies high frequency (for example, 10
When a voltage of 0 Hz or more is applied, a noise filter circuit is connected in front of the converter circuit provided in the light quantity control means to prevent high frequency noise generated when applying voltage to the light emitting display means from leaking to the outside. , To prevent malfunctioning of multiple devices. Further, by providing the light amount control means with a timer circuit, it is possible to display blinking or delayed display of an image.

As a human body detecting means, a distance measuring sensor 5 is arranged substantially in the same plane as the lower part of the mirror means 2 and in front of the mirror means 2 so as to emit a sensor wave. The light amount of the light-emitting display means 3 can be controlled in accordance with the distance. Therefore, regardless of the presence or absence of the human body, the human body
Is easily detected, and the voltage and frequency to the light-emitting display means 3 can be changed and the amount of light emission can be changed according to the situation, so that waste of power can be prevented. For example,
When a person is present in front of and near the mirror device 1, an image is displayed on the surface of the mirror means 2. When no person is present, the display illuminance of the image is reduced, thereby wasting power for image display. To prevent. Further, the image display position and the display image of the mirror unit 2 can be switched according to the distance between the human body and the mirror device 1. In particular, by switching the display range of the image displayed on the mirror means 2 according to the distance from the mirror device to the human body,
By appropriately determining the priorities of the mirror function and the image display function, the image display function can be used effectively without giving the user a sense of incongruity. For example, when there is a person at a place L = 2 m or more from the mirror means 2, an image is displayed on the entire surface of the mirror means 2 and L '
When the camera approaches within 1 m, an image is displayed in a range excluding a substantially central portion of the mirror means 2. Further, by connecting a timer circuit to the light amount control means 4, even if a person moves away from the mirror means 2 for several seconds, it is possible to control such that light emission is not stopped immediately.

By arranging the optical sensor 6 above the mirror means 2 as the illuminance detecting means, it is possible to control the light quantity of the light emitting display means 3 according to the brightness around the mirror device 1. Therefore, the brightness of the surroundings can be easily detected, and the light emission can be changed by changing the voltage and frequency to the light emitting display means 3 in accordance with the situation, thereby preventing waste of power. For example, when the mirror device 1 is installed indoors and the room lighting is turned off at midnight or the like and the room is dark, it is determined that no person is present and the image is maintained in a non-display state, thereby preventing waste of power required for image display. it can. When the mirror device 1 is installed outdoors,
By changing the display illuminance of the image according to the change in the brightness around the mirror device during the day and at night, the image can be displayed with an appropriate brightness, and a constant visibility can always be ensured.

A mirror device provided in a vanity table installed in a washroom or a toilet space has many opportunities for a person to slowly gaze, such as hairdressing and makeup of a face. Advertisements and advertisement images can be displayed without taking up space, and space can be used effectively. In addition, since printed matter such as paper is weak to moisture such as moisture, it is not suitable to be installed in a washroom or toilet space and left for a long period of time, but the luminescent display means provided on the back of the mirror means displays due to deterioration. If it is installed in a public place without causing a defect, it is possible to prevent the advertisement from being hindered by doodles or theft.

Next, as an example of an embodiment of an image display control method according to the present invention, display information of an image is transmitted from a terminal device to a plurality of mirror devices, and the mirror devices are linked to each other so as to be provided on the surface of each mirror means. An image display control method for displaying an image will be described. First, an outline of a mirror device to be used will be described.

As a result, the image displayed on each mirror device 1 can be changed at the timing shown in FIG. Describing the mirror device 1a as an example, display information relating to the display timing of the image shown in FIG. 4 is transmitted from the terminal device 7 to the information processing unit 8a in advance and stored in the information storage unit 9a. (The same applies to the mirror devices 1b, 1c, and 1d.) Then, by turning on the power supply of the mirror device 1a, the information stored in the information storage unit 9a is stored in the information processing unit 8a.
