, Four diode sensors 70,... Are connected as sensors for detecting laser light.

The sensors 70,... Are arranged in the vicinity of the upper end edge of the shaft body 65 and at equally divided positions on the outer periphery. Therefore, when the laser light of the laser light emitting device 73 that normally passes through the inside of the shaft 65 is displaced from the inside of the shaft 65 due to the state in which the rocking body 15 is inclined with respect to the apparatus main body 1, the sensor 70,...
The laser light oscillated from the laser diode 39 is controlled to be switched from the lighting state to the blinking state.

According to the blackout laser device according to the present embodiment having the above-described configuration, two vertical lines extend in the front-rear direction from the laser light emitting devices 30 and 30 and the ceiling point vertically above the laser light emitting device 72. In addition, there is an advantage that the laser light emitting device 73 can project a vertically black background point.

Moreover, according to the oscillator 15 according to the above-described embodiment, regardless of the state where the second connector 16b is engaged with the first connector 16a, the two laser light emitting devices 30, 30 project light. The optical axis of the emitted laser light passes through the axis of the oscillator 15, and the optical axis of the laser light emitted from the laser light emitting devices 72 and 73 is the oscillator 1
Since it coincides with the axis of No. 5, there is an advantage that an extremely accurate blackout operation can be performed based on the axis of the oscillator 15.

This is because the number of connectors 16 is 3 or more,
Accompanying this, even if the number of laser light emitting devices 30 to be attached increases, it means that the accuracy of blackout is not impaired, and by adopting this aspect, the efficiency of blackout work is improved. This has the advantage that the laser device for blackout and blackout can be integrated.

Similarly, the first connector 16a and the second connector 1
6b, that is, by changing the engagement position of the second connector 16b with respect to the first connector 16a, the two vertical lines can be respectively projected in different arbitrary directions. This has the advantage that the efficiency of the blackout operation can be increased and the laser device for blackout can be integrated.

The optical axis can be adjusted by an extremely simple method of operating the three adjusting screws 35,... Into and out of the inner hole 31b. This has the advantage that the cost can be reduced.

Further, since the cylindrical body 38 is configured to be housed and mounted in the inner hole 31b of the holder 31, there is an advantage that the laser light emitting device 30 can be downsized.

Further, since the second movable body 46 to which the columnar lens 47 is attached is attached to the holding body 31 by the fixing member 54 via the elastic body 53, the laser beam from the first movable body 37 which is accurately adjusted is provided. The position of the cylindrical lens 47 can be adjusted by changing the relative distance between the second movable body 46 and the holding body 31 with respect to the optical axis of the light against the elastic force of the elastic body 53. There is an advantage that the displacement of the cylindrical lens 47 can be easily and surely adjusted to project a projection line of high-quality laser light without tilt.

The swing stopping device 5 according to the above embodiment

Have. That is, a conventional disk-shaped non-magnetic metal body mounted coaxially and orthogonally to the rocking body, and a magnetic body mounted to the apparatus main body so as to oppose in a vertical direction with the non-magnetic metal body interposed therebetween. In the swing stop device, when the device body is placed on the inclined ground and the rocking body is tilted with respect to the device body, one side of the non-magnetic metal body is retracted from the facing magnetic body, As a result, the number of lines of magnetic force acting on one side of the non-magnetic metal body and the number of lines of magnetic force acting on the other side of the non-magnetic metal body are significantly different from each other. In addition, a phenomenon occurs in which the other side having many lines of magnetic force is pulled by the magnetic body, and this phenomenon causes a problem that the oscillator does not accurately enter the vertical state. On the other hand, in the rocking stop device 58 according to the above embodiment, even when the device main body 1 is placed on the inclined ground and the rocking body 15 is tilted with respect to the device main body 1, The number of lines of magnetic force acting on one side of the magnetic metal body 60 and the number of lines of magnetic force acting on the other side are substantially the same, and the number of lines of magnetic force acting on both sides is a configuration in which no deviation can occur. There is an advantage that the vertical state can be reliably maintained regardless of the mounting state of the apparatus main body 1.

Further, the sensor 70 according to the above embodiment
According to this, when the device main body 1 is placed on a ground that is greatly inclined and the amount of tilt of the rocking body 15 with respect to the device main body 1 is large, the operator is informed of such a state and an improper use state is determined. It has the advantage that it can be corrected. That is, if the apparatus is continued to be used in such a state, the apparatus may be damaged or the like. However, in the conventional laser for ink marking, such an inappropriate use state cannot be recognized by an operator. There was a problem. On the other hand, in the blackout laser device according to the above embodiment, the oscillator 1
5, the laser light of the laser light emitting device 73 that emits the laser light vertically downward is detected by the sensor 70, and at the same time, the laser light of all or a part of the laser light emitting devices is turned on. Since the control is performed so as to switch to the blinking state, there is an advantage that such a state can be notified to an operator and an inappropriate use state can be corrected.
