b, a micro switch 4c, a switch operating piece 4d, and a coil spring 4e.

As shown in FIG. 1, the illuminating device comprises a translucent container 2, a light projector 3, and a mechanism section 4. Translucent container 2
Is a box whose upper and lower surfaces are made of transparent glass, and is vertically rotatably attached to the arm 1 by a rotating shaft 1a. The translucent container 2 is filled with about half the amount of the liquid 2a.

The light projector 3 is attached to the arm 1 so that the irradiation light direction A faces the light transmitting container 2. The mechanical unit 4 is

When the translucent container 2 rotates in the direction of the arrow a, the switch operation piece 4d provided on the side surface of the translucent container 2 turns on the micro switch 4c. As a result, the power is turned off and the attractive force of the electromagnet 4b disappears, and the translucent container 2 is rotated in the direction of arrow b by the restoring force of the coil spring 1a. When the light-transmitting container 2 rotates in the direction of arrow b, the microswitch 4c is turned off, so that an attraction force is generated again in the electromagnet 4b, whereby the light-transmitting container 2 rotates again in the direction of arrow a.

The translucent container 2 vibrates in the vertical rotation direction B by the mechanical unit 4 repeating such an operation. As a result, waves are generated on the water surface of the liquid 2a in the translucent container 2.
