  FIG. 8 is a longitudinal sectional view showing still another embodiment of the locking member shown in FIG. The locking members 19a and 19b shown in the figure are attachment members that can be replaced with respect to the support mat 7 so as to be compatible with the rings R having various cross-sectional shapes. That is, the locking members 19a and 19b are composed of a partially opened locking portion into which the ring R can be inserted, and a pin portion integrated with the locking portion, and the pin portion is inserted into the support mat 7. Thus, it can be attached to any position of the groove surfaces 7a and 7b. By matching the shape of the locking portion with the cross-sectional shape of the ring R, it is possible to deal with various rings and ornaments. It is also possible to hold and hold one point of the ring R in a supported state.

  Note that the locking members 17a, 17b, 18a, 18b, 19a, 19b as the ornament holding parts described above are formed of members of the same color as the support mat 7 so as not to stand out aesthetically. Is desirable.

  Next, the upper lid 3 is held in an open position that is swung up and down about 80 degrees from a position where the upper opening of the box body 2 is closed. Further, an LED element 6 as a light emitting means is provided on the inner side surface 5 of the upper lid 3.

  This LED element 6 is provided so as to be turned on and off by a switch 9 provided on the back surface of the box body 2. Note that a switch 9 may be provided at the edge of the upper lid 3 that contacts the opening of the box body 2, and the LED element 6 may be turned on and off in conjunction with the opening / closing operation of the upper lid 3.

  In addition, the LED element 6 is disposed on a virtual vertical plane extension including the cut groove 8 with the upper lid 3 swinging up and down to open the box body 2 and mounted horizontally on the support mat 7. The center region including the ring R and its peripheral region is illuminated from a direction deviated by a predetermined angle rearward (Y-axis direction shown in FIG. 1) with respect to the rotation center axis of the placed ring R. That is, the LED element 6 is disposed along the V-shaped cut groove 8 with the top cover 3 opened, and at a position where light is irradiated obliquely from behind the horizontally mounted ring R. Yes.

  Next, an effect operation by the jewelry box 1 having such a configuration will be described. When the switch 9 is turned on by the power supply circuit shown in FIG. 9 with the upper lid 3 opened from the box body 2, the current from the battery 11 is limited to a predetermined amount by the current limiting resistor 12 and supplied to the LED element 6. . As a result, the LED element 6 is turned on, and the LED light is irradiated from the oblique rear side along the cut groove 8 to the ring R placed on the support mat 7 in a horizontal posture.

  As a result, the ring R itself is illuminated and shined, and the shadow S of the ring R projected on the both groove surfaces 7a and 7b of the support mat 7 appears in a heart shape extending forward in the front (FIG. 10). Since such a heart-shaped shadow S is not easily predicted from the shape of the ring-shaped ring R, the jewelry box 1 is highly aesthetic to the observer, and has an unprecedented interest and unexpectedness. A certain production can be provided.

  By the way, the heart-shaped shadow S is determined by the size and shape of the ring R placed horizontally, the shape of the groove surfaces 7 a and 7 b and the positional relationship with the LED element 6.

  Here, FIG. 11 is a model diagram in which these geometrical positional relationships are slightly simplified and expressed in an XYZ coordinate system. Based on this model, the generalized shape of the shadow S projected on the groove surfaces 7a and 7b will be described. In the model shown in FIG. 11, the ring R is assumed to be a circle with a radius r and a height h, and the groove surfaces 7a and 7b are simplified as planes. Further, when the angle formed between the XY plane and the groove surfaces 7a and 7b is φ1, and the light from the LED element 6 is assumed to be approximated as parallel light, the LED element 6 with respect to the rotation center axis (Z axis) of the ring R The angle formed by the light beam from is φ2. Further, the point where the lower surface of the ring R intersects with the rotation center axis of the ring R is set as the origin O of the XYZ coordinate system.

  According to this model, an arbitrary point P (x, y, h) (Equation 1) on the ring of the ring R is projected onto the right groove surface 7b around the LED element 6 or the left groove surface. The coordinates of the point SP (−) projected onto 7a can be expressed by Equation 2 using P parameters (x, y, h).

  FIG. 12 shows an example of the mapping of the point SP group projected on the XY plane of each groove surface 7a, 7b based on this model. Here, FIG. 12 shows a case where the radius r of the ring R is 10 mm, the height h is 5 mm, the angle φ1 of the groove surfaces 7a and 7b is 30 °, and the angle φ2 formed by the Z axis and the light beam is 40 °. The map SPh by the upper end Ph of the ring R and the map SP0 by the lower end P0 are displayed in an overlapping manner. Thus, the projected map onto the groove surfaces 7a and 7b of the ring R by the light irradiated from the light source (LED element 6) at one point on the extended plane along the cut groove 8 has such a heart shape. It can be seen that Furthermore, by forming the groove surfaces 7a and 7b as curved surfaces, the shadow S of the ring can be made more rounded or sharper.

  In the present invention, in addition to the above-described embodiments, for example, two (or a plurality) of LED elements 6 may be arranged on the inner surface of the upper lid 3 and the shadow S of two hearts may be superimposed. It is also possible to dynamically change the shadow S by controlling lighting / flashing of the LED element 6. Further, in a state where the ring R is set up, the shadow may be projected by illuminating from the diagonally rear side in the rotation center axis direction. Furthermore, the ornament is not limited to the ring, and various shapes other than the heart can be produced by appropriately devising the shape of the groove surfaces 7a and 7b according to the ornament to be stored.
