发明名称 FLASHING DEVICE FOR UNDERWATER CAMERA
摘要 PURPOSE:To set the direction and angle of lighting adequately by rotating a flashgun in a plane which contains the center of lighting and a lens optical axis, and then displaying the angle of rotation on a distance display device. CONSTITUTION:A channel-shaped clamping part 13 is formed slantingly atop of an arm 12 provided at one end of a bracket 11, and a flash device 14 is rotatable in a plane P which contains the center (h) of lighting and an optical axis O2. After the flash device is rotated until a desired distance value on a distance index plate 17 coincides with an index 19, a knob 16 is untightened and then the device is fixed at the position. Thus, the direction and angle of lighting are set adequately.
