  Thereby, an alternating electric field is formed between the transparent electrode 22 and the back electrode 25 of the EL backlight 4. As a result, an alternating electric field is formed in the light emitting layer 23, and the charge of the phosphor is excited. Light is emitted (EL emission) by the excited electric charge (light emission state). The emitted light passes through the transparent electrode 22, the base material 21, and the reflective film 3 and is irradiated to the outside. In this state, the user works by looking at his / her appearance and the like reflected on the reflective film 3. Also, the user works by taking out small items such as amenity items from the upper storage portion 13 as necessary.

Thereafter, the paste is dried by heating at about 100 ° C. to about 140 ° C. for several minutes to form the light emitting layer 23.

  Next, a paste in which barium titanate is dispersed in fluororubber resin is printed in a desired pattern on the light emitting layer 23 by screen printing. Thereafter, the paste is dried by heating at about 100 ° C. to about 140 ° C. for several minutes to several tens of minutes. By repeating this step a plurality of times, the dielectric layer 24 having a multilayer structure is formed.

  Next, a paste in which a carbon-based conductive filler is dispersed in a polyester-based resin is printed in a desired pattern on the dielectric layer 24 by a screen printing method. Thereafter, the paste is dried by heating at about 130 ° C. to about 170 ° C. for 10 to 20 minutes to form the back electrode 25.

  Next, the protective layer 26 is formed with a polyester resin.

  Next, the mirror part 5 is completed by forming the reflective film 3 on the surface of the base material 21. Alternatively, the EL backlight 4 and the reflective film 3 may be separately formed on two base materials, and the two base materials may be bonded to produce the mirror portion 5.

  Next, the power supply unit 6 is attached to the lower storage unit 14 of the core unit 2. Thereafter, a connection portion (not shown) formed on the outer peripheral surface of the core portion 2 and a connection portion (not shown) formed on one end portion of the mirror portion 5 are connected to the outer peripheral portion of the core portion 2.

As a result, the user can easily perform operations such as retouching and attaching / detaching contact lenses. Further, the backlit mirror 1 can suppress the influence of the user's shadow when the user approaches and uses it even in a bright place.

  Moreover, since the mirror 1 with the backlight is configured so that the mirror part 5 can be wound around the outer periphery of the core part 2, a large screen can be obtained during use while realizing miniaturization during storage (when not in use). Can be realized.

  Moreover, since the mirror 1 with a backlight forms the upper accommodating part 13 in the core part 2, it can accommodate an accessory. Thereby, the convenience of the user can be improved.

  Further, the mirror with backlight 1 is provided with a switch 33 in the power supply unit 6 for switching the EL backlight 4 on and off. Thereby, consumption of the battery 32 when not in use can be suppressed.

FIG. 8 is a front view of the core near the stopper mechanism. FIG. 9 is a cross-sectional view taken along line IX-IX in FIG. FIG. 10 is a front view of the core portion for explaining the positioning by the stopper mechanism. 11 is a cross-sectional view taken along line XI-XI in FIG. In addition, the same code | symbol is attached | subjected to the structure similar to embodiment mentioned above, and description is abbreviate | omitted.

  In the mirror with backlight 1B according to the third embodiment, the core part 2B is configured as an automatic winding mechanism capable of automatically winding the mirror part 5.

  As shown in FIGS. 6 and 7, the core 2 </ b> B of the mirror with backlight 1 </ b> B includes an inner core 51, a cylindrical part 52, a winding spring 53, and a stopper mechanism 54. The cylindrical portion 52 corresponds to the outer wall portion described in the claims.

  The inner core portion 51 is for the user to hold during use. A space (not shown) for accommodating the power supply unit 6 is formed inside the inner core portion 51.

  The cylindrical part 52 is disposed so as to surround the outer side of the inner core part 51. The cylindrical portion 52 is configured to be movable relative to the inner core portion 51 in the rotation direction. The inner diameter of the cylindrical portion 52 is larger than the outer diameter of the inner core portion 51. As a result, gaps are formed between the inner wall of the cylindrical portion 52 and the outer wall of the inner core portion 51 at regular intervals. One end of the mirror part 5 is fixed to the cylindrical part 52. Further, at the time of storage, the mirror part 5 is wound around the outer periphery of the cylindrical part 52.

  The winding spring 53 is fitted to the outer periphery of the inner core portion 51. The winding spring 53 is installed inside the cylindrical portion 52. That is, the winding spring 53 is installed in the gap between the inner core portion 51 and the cylindrical portion 52. One end 53 a of the winding spring 53 is fixed to the inner core portion 51. The other end 53 b of the winding spring 53 is fixed to the cylindrical portion 52.

  The winding spring 53 is in a state in which no elastic force acts when the mirror unit 5 shown in FIG. 6 is wound. On the other hand, in a state where the mirror part 5 is unfolded, the winding spring 53 exerts an elastic force in a direction (one of the rotation directions) in which the mirror part 5 is rewound between the inner core part 51 and the cylindrical part 52. Let That is, the elastic force of the winding spring 53 acts on the inner core portion 51 in the direction in which the cylindrical portion 52 rotates in the arrow R2 direction.

  The six positioning convex portions 57 are provided so as to protrude from the inner wall of the cylindrical portion 52 toward the center. Here, the sum of the radial height of the positioning convex portion 57 and the radial height of the fixed convex portion 56 is larger than the length of the interval between the outer wall of the inner core portion 51 and the inner wall of the cylindrical portion 52. Thereby, the positioning convex part 57 and the fixed convex part 56 can be made to contact by rotating the inner core part 51 and the cylindrical part 52 relatively. The six positioning convex portions 57 are arranged at equal intervals (60 °) in the circumferential direction. The six positioning convex portions 57 are arranged at the same position in the Z direction. The length of the positioning convex portion 57 in the Z direction is smaller than the distance between the pair of fixed convex portions 56.

Thereby, the inner core part 51 and the cylindrical part 52 can rotate with each other without being obstructed by the stopper mechanism 54.

  On the other hand, when the mirror part 5 is drawn out to a desired length to be expanded and the position is fixed, the cylindrical part 52 is moved relative to the inner core part 51 downward. Accordingly, as shown in FIGS. 10 and 11, even if the elastic force acts on the inner core portion 51 and the cylindrical portion 52 in the winding direction of the winding spring 53, any of the positioning convex portions 57 and the fixed convex portions. 56 abuts and the movement of the inner core portion 51 and the cylindrical portion 52 in the rotational direction is restricted. Thereby, the mirror part 5 is fixed by desired length, without being wound up. Thereafter, when winding the mirror portion 5, the cylindrical portion 52 is moved relative to the inner core portion 51 so that the positioning convex portion 57 is positioned between the pair of fixed convex portions 56. Thereby, the position of the six positioning convex parts 57 in the Z direction is the same as the position in the Z direction of the interval between the pair of fixed convex parts 56, and the inner core part 51 and the cylindrical part 52 are arranged. A relatively rotational movement is possible. As a result, the mirror part 5 is wound up by the elastic force of the winding spring 53.
