Abstract:
PROBLEM TO BE SOLVED: To provide an optical alarm device capable of outputting various alarms.SOLUTION: An optical alarm device 100 includes a light-emitting part 14, a light shielding member 15, and a control circuit of a circuit board 13. The light shielding member 15, in order to control light quantity of the optical alarm device 100, shields at least part of light output from the light-emitting part 14 according to a relative position to the light-emitting part 14, and has an opening 150 expanding in a direction crossing a direction in which the light shielding member 15 moves, and configured to project or retreat the light-emitting part 14. The control circuit of the circuit board 13 is configured to move the light shielding member 15 to a first relative position at which the light-emitting part 14 projects from the opening 150, or a second relative position at which the light-emitting part 14 retreats to the opening 150.SELECTED DRAWING: Figure 2
