PROBLEM TO BE SOLVED: To reduce shaking of an indicating light point caused by hand shaking of an operator with respect to a laser pointer allowing a user to hold and move it for pointing an object with a laser beam. SOLUTION: A laser pointer 11 has a piezo-electric element means 14 for changing a direction of a light beam L by changing a direction of a laser oscillator 13, and when it is used and an angle detection means 15 detects hand shaking of the operator holding the laser pointer 11, a signal processing means 16 alters the direction of the laser oscillator 13 by the piezo-electric element means 14 according to the detected hand shake, and cancels this shaking of the light beam L caused by the hand shaking. Thus, it is possible to prevent the light beam point from shaking caused by hand shaking. |
