<Third Embodiment> A third embodiment of the present invention.
Is shown in FIG. Note that the same names are used for the same or equivalent parts as in the first and second embodiments, and the duplicated description will be omitted.

Reference numeral 30 in the drawing denotes a light reflecting device, which is a reflecting plate via a plurality of cord attaching members attached to the upper end of the supporting member 32, for example, engaging metal fittings 34 engaged with the lower ends of the coil springs 33, respectively. The body 31 is swingably supported.

The support member 32 is formed by rotatably attaching a tip fitting 32b through a bearing (not shown) to the tip of a support shaft 32a fixed vertically to a mounting surface T extending in the horizontal direction.

The support shaft 32a is a rod-shaped body made of a metal such as aluminum or iron or a synthetic resin, and a nut 32c having a predetermined length is provided on the outer periphery of the lower end portion.

Further, a cylindrical cushioning material 32d as a vibration suppressing portion is provided at an intermediate portion of the support shaft 32a.

Each engaging fitting 34 has a lower end penetrating the reflection plate body 31 and fixed by a rivet or the like, and an upper end protruding toward the reflection surface 31a side of the reflection plate body 31 is formed in an annular shape.

Further, the reflection plate body 31 is a laser disk (LD) here, and the recording / reading surface side is a reflection surface 31a. The reflecting surface 11a is colored with a special coating, for example, an effect color such as golden color.

A plurality of blades 31c as a rotating means are fixed to the back surface side of the reflecting surface 31a of the reflecting plate 31 by using bolts or adhesives not shown. Here, the three blades 31c are bent in the same direction to have an L-shaped cross section, and are fixed along the radius of the reflector plate 31 that passes through the positions where the engaging fittings 34 are provided.

Each of the coil springs 33 is attached to the support member 32 by engaging one end thereof with a plurality of rings 32f provided on the flange 32e.

Further, in each coil spring 33, the lower end portion of the support shaft 32a is inserted into the hole portion 31b formed in the center of the reflection plate body 31, and then the engaging metal fitting 34 provided on the reflection plate body 31 is inserted.

Even when each coil spring 33 receives a strong force such as a strong wind, the support shaft 32a inserted into the hole 31b of the reflector plate 31 moves in the horizontal direction of the reflector plate 31. The coil spring 33 is prevented from being excessively bent, and the coil spring 33 is prevented from being damaged.

The support shaft 32a also prevents the reflecting surface 31a of the reflecting plate member 31 from unnecessarily facing sideways or downward, and the reflecting direction of the reflecting surface 31a can be set within a desired range.

Further, when the wind force exceeds a certain level, the reflector plate 31 is held by the support shaft 32a in a tilted state and does not rotate, and there is a risk that the reflector plate 31 will fall off in the event of a strong wind. Reliability will be improved against strong winds.

Even if the inner peripheral edge of the hole portion 31b of the reflector plate 31 comes into contact with the support shaft 32a, the shock is cushioned by the cushioning material 32d to suppress the generation of noise and the like.
It is possible to prevent the reflection plate body 31 from being damaged.

Further, by adjusting the protruding height of the cushioning material 32d from the outer peripheral surface of the support shaft 32a, the reflecting plate 31 is adjusted.
It is possible to easily limit the horizontal movement range of the.

The reflector plate 31 is rotated together with the tip fittings 32b provided on the support member 32 when the plurality of blades 31a receive wind, and further reflects sunlight or the like in an irregular direction. It becomes possible.

The number of parts is small, the occurrence of failures can be reduced, and the reliability can be improved.

Further, since the coil spring 33 is used as the cord attaching member, it is possible to suppress the manufacturing cost by diverting a generally distributed product.

Furthermore, since the LD which is an optical disk is used for the reflector plate 31, it is possible to obtain the reflector plate 31 which can easily generate suitable reflected light. Further, by using the used LD, not only the cost can be reduced but also the resource can be reused, which is useful for environmental protection.

<Fifth Embodiment> A fifth embodiment of the present invention.
Is shown in FIG. It should be noted that the same or equivalent parts as those in the first to fourth embodiments are designated by the same names, and a duplicate description will be omitted.

In the figure, reference numeral 50 denotes a light reflecting device, which is a plurality of cord attachment members attached to the upper end of the support member 52, for example,
The reflection plate body 51 is swingably supported via engagement fittings 54 that are engaged with the lower ends of the chains 55, respectively.

Here, the cord attaching members are four metal chains 55 which are cords having no elasticity and one end of each of which is attached to the supporting member 52 at equal intervals. .

The chain 55 has a relatively short overall length and a pair of short chains 55 facing each other with the support member 52 interposed therebetween.
a and 55a, and long chains 55b and 55b that are formed to have a relatively long overall length and that face each other with the support member interposed therebetween.

Then, the other ends of the chains 55 are engaged with the annular upper ends of the engaging fittings 54 provided on the same circumference of the reflector plate 51, respectively.
Are mounted horizontally.

On the other hand, the buffer cover 51 made of synthetic resin is provided on the inner peripheral edge of the hole 51b formed at the center of the reflector plate 51.
c is attached.

Then, the reflector plate 51 is affected by wind or vibration.
When is shaken, one of the short chains 55a is directed downward and the other short chain 55a is relatively lifted upward, so that the horizontal state of the reflector plate 51 is easily collapsed and the reflector plate 51 is The reflection direction can be irregular.

Further, the long chains 55b and 55b can prevent the reflector plate 51 from being shaken more than necessary, and can prevent the reflector plate 51 from being damaged. Further, the appearance becomes firm and the appearance quality can be improved.

Even if the reflector plate 51 receives a strong force such as a strong wind and the inner peripheral edge of the hole 51b comes into contact with the support member 52, the shock is mitigated by the buffer cover 51c and the generation of noise is suppressed. At the same time, it is possible to prevent the reflection plate body 51 from being damaged.

The first to fifth embodiments of the present invention have been described in detail above with reference to the drawings. However, the specific structure is not limited to the above-described embodiments, and the design is changed within the scope not departing from the gist of the present invention. Even this is included in this invention.

For example, the reflector plate may be an optical disk such as a DVD or MD, or a magneto-optical disk such as an MO,
The reflecting surface may be formed on the surface of a metal plate or a synthetic resin plate by vapor deposition of aluminum or the like.

Further, when the reflector plate is suspended and supported downward, the supporting member and the plurality of cord attaching members are connected through a plurality of rings, but rivets or the like are used to increase the strength. It may be connected via a fixed U-shaped metal fitting.

The reflector plate member and the cord attaching member may be connected to each other via a U-shaped metal fitting fixed by rivets or the like.

In the third to fifth embodiments, the reflector plate is suspended and supported downward by three or four cord attaching members, but the reflector members are attached at positions facing each other with the supporting member interposed therebetween. It may be suspended and supported by a pair of cord attaching members.

In this case, it is easy to lose the balance of holding the reflection plate body horizontally, and it is possible to easily swing even with a slight wind or vibration. Further, the structure is simplified and the weight can be reduced.

Particularly, in the case where the cord attaching member is a chain or the like which is a cord having no elasticity, when one cord attaching portion swings downward, the other cord attaching member relatively moves. Since it swings upward, it becomes easier to lose balance in the horizontal state.

When a strong force such as a strong wind is applied, the supporting member penetrating the reflecting plate body suppresses the shaking of the reflecting plate body and prevents the reflecting plate body from swinging too much.
