Filed: 2002-06-12
Abstract: <P>PROBLEM TO BE SOLVED: To provide a laser pointer which has a timer function and displays the remaining time with low power consumption.  <P>SOLUTION: When a button for laser irradiation in an input part 11 is pushed, illumination in an illuminating part 16 (or display in an outline display part 17) is stopped by a controlling part 12. When the button for laser irradiation is not pushed, a display part which displays the remaining time is illuminated by the illuminating part 16 (or a rough remaining time is displayed by the outline display part 17). This suppresses consumption of the electric power during laser irradiation without checking the remaining time. Further, when a button for displaying the remaining time is pushed, the display in the outline display part 17 is stopped and the display part 15 is illuminated by the illuminating part 16. When the button for displaying the remaining time is not pushed, illumination by the illuminating part 16 is stopped and the rough remaining time is displayed by the outline display part 17. By this method, illumination in the display part 15 by the illuminating part 16 is not simultaneously carried out with the display of the approximate remaining time by the outline display part 17, and this suppresses consumption of the electric power.  <P>COPYRIGHT: (C)2004,JPO
