发明内容 SUMMARY

[0006] 而且,对上述那样的激光指示器设有照射的激光对人体、例如眼睛不产生影响这样的自主标准等,能够从可携带的激光指示器照射的激光的输出被设定为不超过对人体尽量不产生影响那样的一定的值。 [0006] Further, with the irradiation of the laser pointer laser that described above, such as the eyes do not produce such effects independent standards and the like, can be set from the output of the laser pointer portable laser irradiation is no more than the human body does not produce as much as possible the impact of a certain value.
