The present invention is directed to a laser pointer that a user can indicate a particular location by laser.

In the past, in order to properly perform a briefing, the user has various laser pointers that can clearly indicate a specific location by a laser. In addition to the function of instructing the object by the irradiation of the laser, the light diffused and diffused light is also developed, and the function as a lighting fixture (for example, refer to Patent Document 1), or the like, Or a remote operator who performs wireless communication to change the display screen, such as other information processing devices.

Further, as a configuration in which both the laser light and the illumination light can be irradiated as described above, in addition to the configuration shown in Patent Document 1, it is proposed that the user can irradiate the laser and the illumination without changing the laser pointer. Each of the irradiation ranges is formed to overlap each other in a specific place (for example, refer to Patent Document 2).

[Patent Document 1] Japanese Patent Laid-Open Publication No. 2000-260201

[Patent Document 2] Japanese Patent No. 33803031

Further, as described above, the laser pointer is such that the irradiated laser is provided with an autonomous reference for the human body, for example, the eye, and the output of the laser irradiated from the portable laser indicator is not It is configured to exceed a certain value that does not affect the human body as much as possible.

However, the above-mentioned autonomous reference system mainly includes a laser pointer that is only irradiated with a laser, and as described in Patent Document 2, a specific policy can be adopted in which the laser and the illumination are irradiated toward the same place. The status quo is not set.

Here, as the above-mentioned autonomous reference is applied to the configuration as disclosed in Patent Document 2, the light of both sides is simultaneously directed toward the surrounding person, and it is considered that the laser is incident on the surrounding person in particular, especially for the laser. In the case of the eye, when the illumination light enters the state of the eye, it is not sufficient to set the output of the laser to an output that does not affect the eye, and the total output of both lights is considered to be less than or equal to the control. The output is better for the better.

In such a configuration, for example, even if the laser light-emitting means and the illumination light-emitting means are simultaneously irradiated to other persons, it is possible to control the total output of the laser and the illumination to a certain standard or less. . In this way, as a laser pointer that more effectively enhances the safety at the time of use, and the safety of the user and the impression of others at the same time, the performance as illumination and the laser indexer can be provided. The original performance can be achieved with a high level of laser indicators.

The output of the laser light-emitting means can be changed. On the other hand, the light-emitting means of the above-described laser light-emitting means, that is, the light-emitting means for the laser light-emitting means, and the light-emitting means for the illumination light-emitting means are weakened, and the illumination can be changed. The output of the illuminating means.

Further, in a simple configuration, in order to grasp the state of the light-emitting means of either one, the power-on detection circuit for detecting energization of one of the illumination light-emitting means and the laser light-emitting means, and the power-on detection are performed. It is preferable that the control circuit for attenuating the light emission of the other light-emitting means is detected when the circuit detects the energization. Here, the detection of the energization means includes the concept of detecting any voltage, current, or power of any of the energization means. Further, the present invention not only detects the concept of the presence or absence of energization, but also includes the form of detecting the amount of voltage, current, or electric power at the time of energization.

On the other hand, as a state in which the light-emitting means of any one of the above-described light-emitting means can be grasped, the light-emitting detection circuit having the light-emitting means for detecting either of the illumination light-emitting means and the laser light-emitting means, and It is preferable that the control circuit for attenuating the light emission of the other light-emitting means when the light-emitting detection circuit detects the light emission. In this case, not only the concept of the presence or absence of luminescence is detected, but also the form in which the control means is activated via a certain amount of light emission, that is, the form in which the amount of light is detected.

Further, as a light source of the above-described light-emitting means, as a configuration using an LED of a light-emitting diode or a laser diode, it is possible to achieve the above-described configuration by stability.

According to the present invention, when the output of the other light-emitting means is weakened, it is possible to control the total output of the laser light-emitting means and the illumination light-emitting means to a predetermined standard or less. In this way, as a laser pointer that more effectively enhances the safety at the time of use, and the safety of the user and the impression of others at the same time, the performance as illumination and the laser indexer can be provided. The original performance can be achieved with a high level of laser indicators.

The laser irradiation unit 31 has a configuration in which a laser diode is mainly used, and is controlled by a control circuit 8 to be described later. For example, the output is switched at 0.6 mW and 0.4 mW. The laser switch 32 is, for example, a button formed of rubber or the like, and is energized from the power supply unit 5 only when the laser switch 32 is pressed, and the laser emits light. Further, the energizing lamp 33 emits light only when the laser switch 32 is pressed, that is, when the laser beam is irradiated to the laser irradiation unit 31.
