BACKGROUND OF THE INVENTION  
       [0001]     1. Field of the Invention  
         [0002]     The present invention relates to an accessory utilizing a light emitter. More particularly, the present invention relates to an accessory capable of fixing a transparent body detachably utilizing a light emitter.  
         [0003]     2. Related Background of the Invention  
         [0004]     As accessories, rings, earrings, pendants, and the like that utilize gems, imitation doublets, and the like (to be referred to as “accessory bodies” hereinafter) are known. These accessories exhibit unique colors and brilliance when light is transmitted, refracted, or reflected in the accessory bodies, thereby giving aesthetic stimulation to those who see them.  
         [0005]     However, these accessories cannot provide their unique colors and brilliance unless light is incident onto the accessory bodies from the outside.  
         [0006]     The color of a conventional accessory is uniformly determined according to the gem to be used and its arrangement, and the number of kinds of colors depends on combinations of gems used. For this reason, there is no originality in visual stimulation, and the degree of freedom of design is low.  
         [0007]     Furthermore, when a gem is used as an accessory body, it is difficult to work, resulting in an expensive accessory.  
         [0008]     In addition, since a gem is usually fixed to an accessory in a non-detachable manner, it is impossible to enjoy one accessory with many kind of gems.  
       SUMMARY OF THE INVENTION  
       [0009]     It is an object of the present invention to provide an accessory body that utilizes a light emitter and is capable of detachably attaching a transparent body such as a gem. By detachably attaching the transparent body, it is easily possible to change a plurality of transparent bodies on one accessory. Also, it is possible to use the accessory in a wide variety of situations according to time, place and occasion. Further, by providing a family crest, engraved mark, trademark, illustration and the like on the accessory, not only embellishment effect but also discrimination effect can be obtained.  
         [0010]     It is another object of the present invention to provide an accessory which can provide a color and brilliance unique to its accessory body even if no light is incident onto the accessory body from the outside.  
         [0011]     It is still another object of the present invention to provide an accessory which has originality in aesthetic stimulation and a high degree of freedom in design.  
         [0012]     It is still another object of the present invention to provide an accessory which can be easily worked and is relatively inexpensive.  
         [0013]     In order to achieve these objects, according to the present invention, there is provided an accessory utilizing a light emitter, comprising: 
        a transparent body;     a transparent body fixing member for receiving said transparent body;     holding member for detachably attaching said transparent body on said transparent body fixing member;     said light emitter, arranged near the transparent body, for intermittently emitting light upon reception of an electrical signal;     first pulse generator for generating a first pulse signal at a relatively short pulse interval;     photo detector for detecting light incident on said transparent body and generating a light detection signal;     second pulse generator for generating a second pulse signal at a relatively long pulse interval;     signal processor for receiving the first pulse signal, the second pulse signal, and the light detection signal and supplying the electrical signal to said light emitter at a predetermined timing;     a circuit board for mounting said light emitter, first pulse generator, photo detector, second pulse generator and signal processor thereon;     a board fixing member connected to said transparent body fixing member for fixing said circuit board; and     a battery holding member connected to said board fixing member for holding a battery.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0046]     Embodiment 1  
         [0047]      FIG. 1  is a schematic perspective view showing an accessory according to the first embodiment of the present invention,  FIG. 2  is a schematic sectional view of the accessory shown in  FIG. 1 , and  FIG. 3  is a schematic exploded perspective view of the accessory shown in  FIG. 1 . In these figures, the accessory  100  basically comprises the transparent body  1 , a transparent body fixing member  2  for receiving the transparent body  1 , holding member  200  for detachably attaching the transparent body  1  on the transparent body fixing member  2 , a board fixing member  3 , a circuit board  4 , and a battery holding member  5 .  
         [0048]     The surface of the transparent body  1  is cut into, e.g., a polyhedron, so that internal light is satisfactorily reflected, refracted, or diffused by the whole surface. The transparent body  1  may or may not be colored. The transparent body  1  is fixed to the transparent body fixing member  2  of, e.g., plastic, which does not allow light to pass therethrough.  
         [0049]     A holding portion  2   a  for holding the transparent body  1  is formed on the upper portion of the transparent body fixing member  2 , and the transparent body  1  is held thereon through an adhesive or claw (not shown). A coupling portion  2   b  having female threads on its inner surface is formed on the lower portion of the transparent body fixing member  2  to mount the board fixing member  3 . Furthermore, a flange  2   c  is formed at the central portion of the transparent body fixing member  2 . A switch  4   a  fixed on the circuit board  4  is depressed by the flange  2   c . A switch  2   d  is fixed on the surface of the transparent body fixing member  2  and is connected to the circuit board  4  by a lead wire.  
         [0050]     For the holding member  200  of the transparent body  1 , for example, an electrostatic absorption sheet can be used. The electrostatic absorption sheet  200  includes a synthetic resin sheet  201  as a dielectric material and an electrode layer  202  provided integrally on the rear side of the synthetic resin sheet  201  by means of, for example, printing. The electrode layer  202  has a positive electrode  203  and a negative electrode  204  and connected to a battery  6 .  
         [0051]     For the synthetic resin sheet  201 , polyvinyl fluoride, polyvinylidene fluoride and the like which have excellent dielectric property can be used. In order to improve an adhesiveness to printing ink, the rear surface of the synthetic resin sheet  201  is roughened. To the thus roughened rear surface of the synthetic resin sheet  201  conductive ink is printed with a predetermined pattern thereby forming the electrode layer  202  disposed the positive electrode  203  and the negative electrode  204  alternately.  
         [0052]     The board fixing member  3  is formed of a conductive material such as a metal. A first coupling portion  3   a  having male threads on its surface is formed on the upper portion of the board fixing member  3 , and is threadably engaged with the transparent body fixing member  2 . A second coupling portion  3   b  having female threads on its inner surface is formed on the lower portion of the board fixing member  3  so as to mount the battery holding member  5 . A holding portion  3   c  for holding the circuit board  4  is formed between the coupling portions  3   a  and  3   b.    
         [0053]     The light emitter A, the signal processor B, the first pulse generator C, the second pulse generator D, and the photo detector E that will be described in more detail below are assembled on the circuit board  4  with integrated circuits by use of miniature plana mounting print wiring technique. The light emitter A and the photo detector E are arranged on the upper surface of the circuit board. For this reason, light can be emitted toward the transparent body  1 , and external light can be detected. Electronic parts constituting the signal processor B, the first pulse generator C, and the second pulse generator D are arranged on the lower surface of the circuit board. Furthermore, a contact member  4   b  for a battery  6  is formed on the lower surface of the circuit board  4 .  
         [0054]     The battery holding member  5  also serves as a battery lid, and is formed of a substantially disk-like conductive material. For this reason, a coupling portion  5   a  having male threads is formed on the peripheral surface of the battery holding member  5 , and is threadably engaged with the board fixing member  3 . A projection  5   b  is formed on the upper surface of the battery holding member  5  to constitute a contact for the battery  6 . The battery  6  is clamped between the contact member  4   b  formed on the lower surface of the circuit board  4  and the projection  5   b  to supply power to the electronic parts assembled on the circuit board  4 . Since a groove  5   c  is formed on the lower surface of the battery holding member  5 , the battery holding member  5  can be easily attached/detached.  
         [0055]     The accessory  100  according to the first embodiment is constructed as mentioned above, the operation of which is explained as follows.  
         [0056]     In FIGS.  1  to  4 , the battery holding member  5  is first removed from the board fixing member  3 , a battery is inserted into the bottom portion of the board fixing member  3  and then the battery holding member  5  is closed to accommodate the battery  6 . By tightening the screw of the first coupling portion  3   a , the transparent body fixing member  2  is attached to the board fixing member  3 . At this time, a switch  4   a  is closed. Then, current from the battery  6  is supplied to the electrode layer  202  having the positive electrode  203  and the negative electrode  204  and the electrostatic attractive force caused by the electrode layer  202  will fix the transparent body  1  to the transparent body fixing member  2 .  
         [0057]     When removing the transparent body  1 , the screw of the first coupling portion  3   a  is released to open the switch  4   a . This will stop the application of current to the electrode layer  202  and eliminate the electrostatic attractive force. Therefore, the fixing and releasing of the transparent body  1  can be performed easily by the open/close operation of the switch  4   a . It should be noted that the power switch is not limited to the switch  4   a  but it is possible to provide it to the outside of the accessory  100 , such as the portion of the switch  2   d . In this case, the fixing and releasing of the transparent body  1  can be performed by means of the outside switch without releasing the screw of the first coupling portion  3   a.    
         [0058]      FIG. 5  shows the basic structure of the accessory  100  according to the first embodiment of the present invention. The present invention basically comprises a light emitter A, a signal processor B, a first pulse generator C, a second pulse generator D, and a photo detector E. The disclosure of the U.S. Pat. No. 4,973,835 is incorporated herewith by reference.  
         [0059]     The light emitter A is arranged on or near a transparent body  1 , and is connected to the signal processor B. The signal processor B is connected to the first pulse generator C, the second pulse generator D, and the photo detector E.  
         [0060]     One or a plurality of light-emitting members A may be arranged, and a light-emitting element such as an LED may be used. The light emitter A externally emits light through the transparent body  1 . The first pulse generator C generates a first pulse signal having a relatively short pulse interval, and the second pulse generator D generates a second pulse signal having a pulse interval at least longer than the first pulse signal. The photo detector E detects light incident from the transparent body  1 , and generates a light detection signal. These signals are supplied to the signal processor B and are subjected to predetermined signal processing.  
         [0061]     More specifically, only when the signal processor B receives the second pulse signal and does not receive the light detection signal, it controls a light-emission timing to cause the light emitter A to emit light based on the first pulse signal. For this reason, when light is not incident by the transparent body  1 , the light emitter A is repeatedly turned on/off to intermittently emit light. In this case, an ON/OFF time depends on the pulse interval of the second pulse signal.  
         [0062]     The circuit arrangement of the light emitter A, the signal processor B, the first pulse generator C, the second pulse generator D, and the photo detector E will be described below with reference to  FIG. 6 . In this embodiment, four light-emitting elements are used for the light emitter A; a 4-bit binary counter (for example, SN74HC161 of Texas Instruments Co.) for the signal processor B; a clock oscillator for the first pulse generator C; a monostable multivibrator for the second pulse generator D; and a photosensor for the photo detector E.  
         [0063]     The first pulse generator C comprises, e.g., a NAND Schmitt gate  11 , a resistor R 1 , and a capacitor C 1 . The output terminal of the NAND Schmitt gate  11  is connected to the signal processor B. This output terminal is also connected to the resistor R 1 . The resistor R 1  is connected to the “plus(+)” terminal of the capacitor C 1 . The “minus(−)” terminal of the capacitor C 1  is connected to ground. One input terminal of the NAND Schmitt gate  11  is connected between the resistor R 1  and the capacitor C 1 , and the other input terminal is connected to one input terminal of an OR gate  12  connected to the clear (CLR) terminal of the signal processor B.  
         [0064]     The photodetector E comprises, e.g., Schmitt inverter gates  13  and  14 , a photosensor P 1 , resistors R 2  and R 3 , and a capacitor C 2 . The output terminal of the Schmitt inverter gate  14  is connected to the input terminal of the OR gate  12 . An integral circuit constituted by the resistor R 3  and the capacitor C 2  is connected between the Schmitt inverter gate  13  and  14  and the input terminal of the Schmitt inverter gate  13  is connected between the resistor R 2  and the photosensor P 1 . The line from the resistor R 2  and the photosensor P 1  serves as a power supply line connected to the switch  4   a  and the battery  6 .  
         [0065]     The second pulse generator D comprises, e.g., a NAND Schmitt gate  15 , a diode D 1 , a resistor R 4 , and a capacitor C 3 . The output terminal of the NAND Schmitt gate  15  is connected to the other input terminal of the OR gate  12 . The input terminal of the NAND Schmitt gate  15  is connected to the signal processor B. The resistor R 4  is connected between the output terminal of the NAND Schmitt gate  15  and the other input terminal of the OR gate  12 . The diode D 1  is connected in parallel with the resistor R 4 . The capacitor C 3  is connected to a line for connecting the power supply line and a line connecting the resistor R 4  and the input terminal of the OR gate  12 .  
         [0066]     The signal processor B receives the pulse signal from the first pulse generator C, the light detection signal from the photo detector E, and an operation stop signal from the second pulse generator D, and outputs electrical signals to its output terminals Q 0 , Q 1 , Q 2 , and Q 3  at predetermined timings. These output terminals are connected to light-emitting elements L 1 , L 2 , L 3 , and L 4  through resistor R 5 , R 6 , R 7 , and R 8 , respectively. For this reason, these electrical signals are sent to the light-emitting elements L 1 , L 2 , L 3 , and L 4  at predetermined timings. Further, switch  2   d  is connected between the signal processor B and the power supply line through resistor Rp. The switch  2   d  is connected to ENP terminal in case that a 4-bit binary counter is used for the signal processor. For this reason, closing the switch  2   d  changes the input signal of ENP terminal from low to high and its output state of the output terminals Q 0 , Q 1 , Q 2 , and Q 3  is maintained.  
         [0067]     The operations of this circuit in low and high illumination cases will be described below in turn. First, low illumination case (i.e., a case wherein no light is incident) will be described below. When the switch  4   a  is closed, the internal resistance of the photosensor P 1  is increased, and after the lapse of a time determined by a time constant of the resistor R 2  and the capacitor C 2 , the output of the Schmitt inverter gate  13  goes low. Therefore, the output of the Schmitt inverter gate  14  goes high. The interval of high output of the Schmitt inverter gate  14  can be arbitrarily determined by the time constant of the resistor R 3  and the capacitor C 2 . When the output from the Schmitt inverter gate  14  goes high, the output from the NAND Schmitt gate  11  goes high. Thus, the first pulse generator C starts self-excited oscillation (free running). For this reason, a pulse signal having a short pulse interval shown in  FIG. 7A  is supplied to the signal processor B.  
         [0068]     In a steady state, since the signal processor B supplies a low-level signal to the NAND Schmitt gate  15 , the output from the NAND Schmitt gate  15  is set at high. For this reason, a high signal is input to the input terminal of the OR gate  12 . As a result, since the high signals are input to the input terminals of the OR gate  12 , a high signal is output. Thus, the signal processor B is enabled, and electrical signals shown in  FIGS. 8D, 8E ,  8 F, and  8 G are supplied to the light emitter A. After the lapse of a predetermined period of time (until  16  pulses are input to the signal processor B), a carry signal (CR) is supplied from the signal processor to the NAND Schmitt gate  15  ( FIG. 8B ), thus inverting the signal output from the second pulse generator D. In this case, since the signal is converted from high to low, a signal input to the CLR terminal of the signal processor B goes low ( FIG. 8C ). In this manner, when the carry signal is input, the output signal from the second pulse generator D can be changed, as shown in  FIG. 7 . If pulse intervals shown in  FIG. 6  are represented by T 1  and T 2 , the signal processor B is enabled for the time interval T 2 , and is disabled for the time interval T 1 . After the lapse of time determined by the time constant of the resistor R 4  and the capacitor C 3 , the signal output from the second pulse generator D goes to high again, and the signal processor B is enabled again.  
         [0069]     Even if it becomes dark and the internal resistance of the photosensor P 1  is increased, the output from the Schmitt inverter gate  13  does not go low unless the time determined by the time constant of the resistor R 2  and the capacitor C 2  has elapsed. Therefore, the operation of the signal processor B will not be interrupted by an ON state of the light emitter A.  
         [0070]      FIG. 9  shows timings at which the signal processor B supplies the electrical signals to the light emitter A in an enabled state. In this case, the light-emitting element L 1  emits light in response to a first clock, the light-emitting element L 2  emits light in response to a second clock, and the light-emitting elements L 1  and L 2  emit light in response to a third clock. In this manner, when the 4-bit binary counter is used, a large number of combinations or patterns of light emission can be realized. Further, present emitting state can be maintained when the switch  2   d  is closed in the enable state.  
         [0071]     Under high-illumination, since the light detection signal is supplied to the signal processor B, the internal resistance of the photosensor P 1  is decreased, and the output from the Schmitt inverter gate  13  goes high. Therefore, the output from the Schmitt inverter gate  14  goes low. The interval of low output from the Schmitt inverter gate  14  can be arbitrarily determined by the time constant of the resistor R 3  and the capacitor C 2 . When the output from the Schmitt inverter gate  14  goes low, the output from the NAND Schmitt gate  11  goes low. Therefore, oscillation of the first pulse generator C is stopped. In this case, since one input signal of the OR gate  12  goes low, the output signal from the OR gate  12  goes low regardless of the input signal from the second pulse generator D. Thus, the signal processor B is kept cleared. In this case, since no pulse is input from the first pulse generator C, no carry signal is supplied from the signal processor B to the second pulse generator D.  
         [0072]     Embodiment 2  
         [0073]     In the first embodiment, the electrostatic absorption sheet  200  as a holding member of the transparent body  1  is explained. However, the present invention is not limited to the embodiment, it is possible to adopt a shape memory alloy as a holding member of the transparent body  1 .  
         [0074]      FIG. 10A  depicts the situation where the transparent body  1  is detachably attached by the tip  303  of the fixing portion  302 . In the figure, the transparent body  1  of the accessory  101 A is detachably attached to the a transparent body fixing member  2  by means of the transparent body holding member  300  providing a shape memory alloy.  
         [0075]      FIG. 10B  is a schematic sectional view showing an accessory  100 A according to the second embodiment of the present invention. In the figure, the transparent body holding member  300  comprises a heat collecting member body  301  composed of a good conductive metal such as aluminum or silver and unguiform fixing portion  302  made of shape memory alloy. The fixing portion  302  is attached to the tip portion of the heat collecting member body  301  by means of caulking or brazing.  
         [0076]     When the light emitter is illuminating, the battery  6  will generate heat. The generated heat is received by the leg portion  304  disposed to contact the battery  6  and then transmitted to the heat collecting member body  301 . The heat is further transferred to the fixing portion  302  made of shape memory alloy. The shape memory alloy has a property of bending when heated. Therefore, the tip  303  of the fixing portion  302  is bent inwardly and will fix the transparent body  1 . On the other hand, when the switch  4   a  is opened, the battery  6  will not generate heat. Then, the temperature of the fixing portion  302  returns to the ambient temperature and the fixing portion  302  will move to the extended position as shown by the dashed line in  FIG. 10B . This enables the release of the transparent body  1 .  
         [0077]     For the shape memory alloy, nonferrous type shape memory alloy such as Nickel-Titanium alloy or Copper alloy, and ferrous type shape memory alloy such as Iron-Platinum alloy, Iron-Nickel-Cobalt-Titanium alloy, Iron-Palladium alloy and other kind of shape memory alloy can also be applied. The shape of the fixing portion  302  is not limited to that depicted in  FIGS. 10A and 10B , but various other shapes can also be used.  
         [0078]     Since the constructions and operations of the light emitting section in the second embodiment (and in the following embodiments) is same as that in the first embodiment, the explanation thereof is omitted.  
         [0079]     Embodiment 3  
         [0080]      FIG. 11A  depicts the states where the transparent body  1  is detachably attached by the fixing portion  306  of the transparent body holding member  305 . In the figure, the transparent body  1  of the accessory  10 A′ is detachably attached to the a transparent body fixing member  2  by the means of the holding member  305 .  
         [0081]      FIG. 11B  is a schematic sectional view showing an accessory  100 A′ according to the third embodiment of the present invention. In the figure, the transparent body holding member  305  comprises a heat collecting member body  301  made of a good heat conductive metal such as Aluminum or Silver and an unguiform fixing portion  306  made of the same metal as that of the heat collecting member body  301 .  
         [0082]     As in the same manner in the second embodiment, the heat from the battery  6  is received by the leg portion  304 , which is disposed to contact the battery  6 , and is transmitted to the heat collecting member body  301 . This heat will expand the fixing portion  306  so as to fix the transparent body  1 . On the other hand, when the switch  4   a  is opened, the battery  6  will not generate heat. Then, the temperature of the fixing portion  306  returns to the ambient temperature and the fixing portion  302  will contract to the original size. This enables to release the transparent body  1 .

         [0088]      FIG. 14A  is a schematic sectional view showing an accessory according to the sixth embodiment of the present invention and is basically same construction as the accessory depicted in  FIG. 2 . Differences from  FIG. 2  are that an aromatic material  150  is disposed on the side of the board fixing member  3  and a heat collecting member  151  for transferring the heat from the battery  6  to the aromatic material  150 . The effect of the aromatic material can pleasantly stimulate the sense of smell of persons near the person wearing the accessory  100 D.  
         [0089]     As mentioned above, when the light emitter is illuminating, the battery  6  will generate heat. The heat is received by the heat collecting member  151  and transmitted to the aromatic material  150  so as to warm it. Then the aromatic material  150  generates an aromatic aroma and the aroma is diffused outside of the accessory  100 D through openings  152 .  
         [0090]     The aromatic material  150  has a ring shape as shown in  FIG. 14B  and may have cut-away portion (not shown) to enable easy attachment to the board fixing member  3 . As for the aromatic material  150 , non-woven fabric of cotton or plastics soaked with liquid aromatic material can be used and the aromatic material may be jelly or a solid.

         [0095]      FIG. 16  is a perspective view showing an accessory such as a finger ring according to the eighth embodiment. In  FIG. 16 , for example, a finger ring  600  comprised of an accessory  100  is placed on the pedestal  500  having a built-in AC adapter (not shown). The finger ring  600  is composed of the accessory  100  accommodating a rechargeable battery (not shown) and the ring  601  attached thereto. By using the rechargeable battery, it is possible to minimize the burden of opening the battery holding member  5  and changing the battery  6 . In addition, since sufficient battery power can be supplied, it is possible to minimize the transparent body  1  reliably when using the transparent body holding member  300  providing the electrostatic absorption sheet  200  or shape memory alloy. Although only the accessory  100  is explained in this embodiment, this embodiment can also accommodate accessories  100 A to  100 E.  
         [0096]     The finger ring pedestal  500  provides terminals  501  which contact with terminals (not shown) formed on the inner side of the finger ring  600 . Terminals  501  make it possible to charge the rechargeable battery. Alternatively, it is possible to adopt non-contact terminals which are chargeable through an electromagnetic induction.  
         [0097]     Note that the present invention is not limited to the above embodiments. For example, the light emitter A, the signal processor B, the first pulse generating means C, the second pulse generator D, and the photo detector D need not be assembled on a single circuit board.  
         [0098]     Further, this invention can be applied to a sash clip, a tiepin, a necklace, a bracelet, etc. In the above-mentioned embodiments, light emitting elements such as LED are used as the light emitter A, however, CCD, liquid crystal and other light emitting member can also be used.
