IPC: G02B27/20
Filed: 2002-08-08
Abstract: <P>PROBLEM TO BE SOLVED: To provide a laser pointer of small power consumption and low price.  <P>SOLUTION: Two or more set time points are previously inputted by a key inputting section 3. When lecture beginning is inputted via the key inputting section 3, a controlling section 2 outputs continuous emitting signals to a red laser light emitting section 1a to make the section 1a continuously emit red laser beams and to make a timer section 5 start time counting. When counted time in the timer section 5 exceeds the set time point, the controlling section 2 stops output of the continuous emitting signals to the red laser light emitting section 1a and meanwhile outputs the continuous emitting signals to a green laser light emitting section 1b. Thereby color of laser beam of the laser pointer indicating an image or a display object changes from red to green. Consequently, lapse of set time is certainly recognized by a user. Separate provision of a vibrator or the like for notifying the user of time lapse is unnecessary and thereby the laser pointer which can display time lapse with small number of parts and at a low cost, is obtained.  <P>COPYRIGHT: (C)2004,JPO
