  Furthermore, in the nail decoration sheet of the present invention, the connector portion on the artificial nail body side includes a reset switch that detects that a battery is mounted, and the electronic paper is displayed when the reset switch is turned on. The display driving means provided for driving is reset.

  According to the above configuration, when the battery is removed, in some cases, the display driving means for displaying and driving the electronic paper erases the display data such as the images and characters or causes an error in the system. Or Therefore, the display can be quickly restored by providing a reset switch in the connector part on the artificial nail body side and applying a reset when the battery is attached.

  In addition, the nail decoration sheet of the present invention includes an artificial nail body that is attached to a user's nail and an electronic paper that is provided on the surface of the artificial nail body, and displays any image or character on the electronic paper. In the nail decoration sheet, the electronic paper is disposed on the nail plate on the distal end side from the center of the user's nail, and is raised on the nail half moon on the proximal end side of the user's nail. A plurality of decorative portions are provided, and a battery that supplies electric power for display driving of the electronic paper is disposed in the decorative portion.

  According to the above configuration, in the nail decoration sheet used as an artificial nail, the electronic paper can be displayed on the surface by using the electronic paper, and the electronic paper has a tip from the center of the user's nail. On the nail half on the base end side of the user's nail, one or more raised decorative parts are provided, for example, imitating gemstones or crystals. And in the decoration part, the battery which supplies the electric power for carrying out the display drive of the said electronic paper can be arrange | positioned without a sense of incongruity.

  Therefore, even if an arbitrary image or character is displayed, in the past, it has been difficult to display only a still image using nonvolatile electronic paper in terms of power consumption. Since the capacity of the battery to be embedded can be made relatively large, it is possible to perform a frame advance image that is updated and displayed at an appropriate timing, a moving image for a short time, or an updated display of a full-color image. Thus, the nail decoration sheet that can display an arbitrary image or character by using electronic paper can be interesting or more attractive.

It is a figure for demonstrating the usage method of the nail | claw decoration sheet which concerns on further another form of implementation of this invention.

(Embodiment 1)
Drawing 1 is a figure for explaining the usage method of nail decoration sheet 1 concerning one embodiment of the present invention. In the example of FIG. 1, the nail decoration sheet 1 according to the embodiment is attached only to the index finger 22 among the five fingers 21 to 25 of the user's hand 2 as artificial nails, and the remaining fingers 21, 23 to 25. Shows an example in which old nail decoration sheets 31 and 33 to 35 on which images and characters are printed are pasted. However, the nail decoration sheet 1 which concerns on embodiment may be affixed on all the fingers 21-25 from multiple pieces. Which finger out of the five fingers 21 to 25 uses the nail decoration sheet 1 according to the embodiment depends on cost and design (for example, when all five fingers 21 to 25 are used) , Etc.) may be considered in consideration. As will be described later, the nail decoration sheet 1 operates in cooperation with a so-called smartphone 4 or a tablet terminal (not shown).

  2 and 3 are an enlarged plan view and a longitudinal sectional view showing the vicinity of the nail decoration sheet 1 from the index finger 22 of the user. As shown in FIG. 2, the nail decoration sheet 1 includes an artificial nail body 11, an electronic paper 12 provided on the surface of the artificial nail body 11, and decoration parts 13 to 15. The electronic paper 12 is arranged on the nail plate on the distal end side from the center of the user's nail 221, and a plurality of electronic papers 12 are arranged on the nail half moon on the proximal end side of the nail 221 along the arc shape of the half moon (FIG. 3) three decorative portions 13 to 15 are arranged.

  The electronic paper 12 is for the index finger 22, and for example, the display screen 121 has a width W of 7 mm and a length L of 10 mm. On the outside of the display screen 121, row electrodes and column electrodes are formed on at least two sides, and these electrodes are folded inside the artificial nail body 11 or covered on the electronic paper 12. It is covered with the design of the protective sheet that does not, and is not visible from the surface side.

  For the electronic paper 12, an electrophoretic method can be used as a typical display technique. In this method, white and black particles are moved by an electric field in a microcapsule containing a fluid to display white and black, which is also called a particle movement type. The display method of the electronic paper 12 can be used in various ways, but has high contrast, does not require power to maintain display, and can rewrite the display with little power. Is preferred.

  As shown in FIG. 3, the decorative portion 14 is a dummy jewel, and is formed by a raised outer shell 141 realized by a glass dome or the like and vapor deposition on the inside thereof, and reflects light from the outer shell 141. And a reflective layer 142 to be configured. The same applies to the other decorative portions 13 and 15. That is, the decoration parts 13-15 are realizable by covering the glass ball which gave the coating inside. For example, a substrate 145 on which the main control circuit 143 and the memory 144 are mounted is accommodated in the internal space of the dome of the decoration portion 14, and a coil that generates excitation electromotive force by NFC is accommodated in the decoration portion 13. In the decoration part 15, a communication circuit by NFC is accommodated.

  In NFC, the coil corresponds to ISO / IEC14443, which is also used for electronic payment with IC cards and mobile phones, for example, and a distance of a few tens of centimeters using a frequency of 13.56 MHz. Thus, a power receiving means capable of receiving power is configured. On the other hand, the communication circuit is for communicating with the smartphone 4 by using, for example, 2.4 GHz Bluetooth (registered trademark) or a wireless LAN using the electromotive force generated by the coil. Since NFC frequencies such as 13.56 MHz are managed by the Radio Law, if the excitation power can be transmitted at a frequency outside the jurisdiction of the Radio Law, complicated procedures are eliminated, and the transmission power is increased and shortened. Power transmission can be performed in time, which is preferable.

  Thus, in the nail decoration sheet used as an artificial nail, in order to be able to display an arbitrary image or character using the electronic paper 12 on the surface, it should be noted in the nail decoration sheet 1 of the present embodiment. The artificial nail body 11 is formed to extend from the user's toe 222, and a battery 16 for supplying power for driving the electronic paper 12 is disposed on the back side 112 of the portion 111 extending from the toe 222. It has been done.

  This utilizes the fact that artificial nails used for decorative purposes are often formed longer (so as to appear larger) than the length of the user's nails 221 in order to improve the appearance. Usually, both sides of the claw 221 are curled, and a dome-shaped space 113 exists on the back side 112 of the portion 111 extended from the claw 221 due to the curl. The battery 16 can be embedded without a sense of incongruity.

  The battery 16 and the electronic paper 12 are connected to the substrate 145 by wirings 171 and 172. Thus, the image and character data stored in the memory 144 is read by the main control circuit 14 and displayed on the electronic paper 12 by the power of the battery 16. As the battery 16, a flexible organic radical battery having a relatively large capacity per volume can be used.

  Therefore, even if an arbitrary image or character is displayed, the nail decoration sheet according to the present embodiment is conventionally difficult to display only a still image using a non-volatile electronic paper in terms of power consumption. 1, since the capacity of the battery 16 embedded in the space 113 can be relatively large, a frame-advanced image that is updated and displayed at an appropriate timing, a moving image for a short time, or an updated display of a full-color image can be displayed. become able to. Moreover, since power consumption can be increased, the possibility of using a self-luminous material such as an organic EL element for the electronic paper can be opened. In that case, visual recognition in a dark place becomes possible. In this way, the nail decoration sheet 1 that can display an arbitrary image or character by using the electronic paper 12 can be interesting or more attractive.

  Specifically, the operating voltage of the electronic paper 12 is 1.65 to 3.6V, preferably 1.65V. On the other hand, the operating voltage of the driver of the electronic paper 12, which is the main control circuit 143, is 2.6 to 2.7 V, and the operating current value is about 40 mA at the maximum and close to 0 at the time of sleep, about 0.05 mA. . Therefore, if the capacity of the battery 16 is at least 3V and 10 mAh, two organic radical batteries are used in series, and if the image is exchanged once per hour or only information is displayed once, it is 15 It can be operated for a period of time, and the animation can be displayed continuously for about 10 minutes.

  Such a capacity can be realized by the battery 16 embedded in the space 113 of the toe 222. For example, the length of the portion 111 extending from the toe 222 is 7 to 8 mm, and it may exceed 1 cm in the case of the thumb 21 that does not get in the way when the hand 2 is gripped (outside). The battery 16 having the above capacity can be accommodated. In particular, the long and wide thumb 21 can accommodate a large capacity battery.

  Here, at present, the operating voltage of the electronic paper 12 is lower than the operating voltage of the driver. Therefore, when the voltage becomes low, the driver stops first. Therefore, when electronic paper without a driver appears, the operation time can be further extended.

  FIG. 4 shows an example of the frame advance image. FIG. 4A is a plan view of the nail decoration sheet 1, and FIGS. 4B to 4F are diagrams illustrating an enlarged frame advance image displayed on the electronic paper 12. The example of FIG. 4 shows a state in which a four-leaf clover blooms. After the stem 181 shown in a heart shape is extended as shown in FIG. 4B to FIG. 4C, FIG. As shown in FIG. 4D from FIG. 4D, the flower 182 blooms, and as shown in FIG. 4F, the petal 183 is scattered and scattered.

  Furthermore, in the nail decoration sheet 1 of the present embodiment, as shown in FIG. 3, the battery 16 is disposed from the inner side of the tip end 114 of the artificial nail body 11 by a predetermined length D1 to the user's fingertip 223. The The length D1 is 1 mm, for example. Therefore, when the user grasps the pen or grasps the fist, the toe (tip 114) comes in contact with the palm 16 or the like before the battery 16 comes into contact with the palm or the like.

  Further, in the nail decoration sheet 1 of the present embodiment, as shown in FIG. 3, the battery 16 extends from a position away from the user's fingertip 223 by a predetermined distance D2 to the tip 114 side of the artificial nail body 11. Be placed. The distance D2 is 1 mm, for example. Therefore, when the user touches the fingertip 223 and spreads flatly as shown by the phantom line 224 in FIG. 2, for example, by putting his hand on the desk, the battery 16 contacts the fingertip 223. It is possible to suppress the uncomfortable feeling given to the user. In the state of FIG. 3, the gap D <b> 3 is secured between the battery 16 and the fingertip 223 even when the fingertip 223 is expanded.

  Here, even in the same NFC, the frequency of 13.56 MHz used for an IC card, a wireless tag, or the like is used for power reception by the coil. Accordingly, the power received by the coil can be used for charging the battery 16 by using the power for exciting the IC card or the wireless tag, and the coil functions as a power receiving means. In this way, it is possible to supply power for charging in a non-contact manner, and it is possible to eliminate structurally weak parts such as electrodes and improve airtightness compared to the case where contact power feeding is performed by providing electrodes. The degree of freedom (range of movement) of the user's finger 22 during charging can be increased.

  On the other hand, communication with the smartphone 4 or the like is also performed in a non-contact manner using the 2.4 GHz frequency band or the like. Therefore, as compared with the case where data is received by contact by providing a terminal, it is possible to eliminate structurally weak portions such as electrodes and improve airtightness. In addition, since data can be transmitted at an arbitrary timing as long as it is within a communicable range, convenience for display update can be improved.

  Furthermore, in the nail decoration sheet 1 of the present embodiment, data for display as shown in FIG. 4 is transmitted from the smartphone 4 or a tablet terminal. In the smartphone 4 or tablet terminal, it is easy to select (extract, download) and edit a favorite image or character. Moreover, in the smart phone 4 or the tablet terminal, the favorite image or character data can be easily transferred to the nail decoration sheet 1. Thus, by using the smartphone 4 or the tablet terminal, it is possible to easily display a favorite image or character on the nail decoration sheet 1 used as an artificial nail.

Moreover, since the transmission source of the display data is the smartphone 4 or the tablet terminal, the display data to be transmitted is the data of the email received by the smartphone 4 or the tablet terminal. Can read and improve interest.
(Embodiment 2)
Below, the nail | claw decoration sheet which concerns on the other form of implementation of this invention is demonstrated. The main configuration is the same as that of the nail decoration sheet 1 shown in FIGS. The artificial nail body 11 is made of a shape memory gel or synthetic resin, and is constructed by mounting an electronic paper 12 on the upper surface thereof and covering the whole with a waterproof transparent film or applying a waterproof coating to the outer periphery. By embedding an NFC coil in the artificial nail body 11, particularly in the outer peripheral portion, the coil diameter is increased, the coil length is increased, and the amount of power that can be received can be increased.

  Then, the NFC coil can be eliminated from the interior of the decorative portion 13, and the battery can be accommodated in the dome of the decorative portion 13, although the capacity is somewhat smaller than that of the battery 16 of the toe 222. . In that case, the battery in the decoration unit 13 is used for the expansion (capacity increase) of the battery 16, and the electronic paper 12 displays a moving image, a full color image, or extends the display time. Also good.

However, the battery 16 in the decorative portion 13 may be replaced, that is, the battery 16 at the toe 222 may be eliminated. In that case, in the artificial nail body 11, the portion 111 extending from the toe 222 can be shortened.

  The insulating heat insulating sheet 18 is provided to prevent electric leakage and heat transfer from the substrate and the printed antenna layer 19 side to the user's finger 22 side, and depending on the material and thickness of the artificial nail body 11a, In the case where an effect can be expected, the insulating heat insulating sheet 18 may not be particularly provided. In the insulating heat insulating sheet 18, a through hole 181 for electrically connecting the battery 16 a to the substrate and the printed antenna layer 19 is formed on the toe 222 side corresponding to the mounting position of the battery 16 a. .

  The substrate and the printed antenna layer 19 are, for example, a flexible substrate on which a bare chip such as the main control circuit 143, the memory 144, and the NFC communication circuit is mounted on the substantially central portion side, and the NFC communication coil is provided on the outer peripheral portion. Formed and configured. The substrate and the printed antenna layer 19 and the electronic paper 12 a are connected to each other by a flexible substrate 173 on the base end side of the claw 221, that is, on the nail half moon. A protective sheet 20 is placed on the electronic paper 12a. The protective sheet 20 is formed so that the area of the display screen 121 is transparent, and the periphery is formed so as to block light so as to hide the row electrodes and column electrodes. In addition, a design may be appropriately given.

  By configuring in this way, the nail decoration sheet 1a can be made thicker than the nail decoration sheet 1, but the decoration portions 13 to 15 for camouflaging the substrate 145 and the coil can be made unnecessary. Moreover, in this nail | claw decoration sheet 1a, the coil diameter of NFC can be enlarged and the communication distance with the smart phone 4 can be extended. The nail decoration sheet 1a having the laminated structure and the nail decoration sheet 1 including the decoration portions 13 to 15 may be appropriately selected according to the design properties and the like.

  Moreover, what should be noted in the nail decoration sheet 1a is that the battery 16a is configured to be detachable from the artificial nail body 11a. In FIG. 6, the battery 16a portion is shown in an enlarged manner in the region indicated by reference symbol A.
