Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to an angle adjustment device for a light transmitter/receiver for optical space transmission.

[Prior art and its disadvantages] Conventionally, in this type of angle adjustment device, the third
As shown in FIGS. 5 to 5, a mounting bracket 202 is attached to a bottom plate 201 by bolts 203, washers 204, and nuts 205 so as to be rotatable in the left-right direction. The free end of the mounting plate 207 of the light transmitter/receiver 206 for optical space transmission is attached to the mounting bracket 202 so as to be rotatable in the vertical direction with a screw 208, and the free end of the other mounting plate 209 is It was attached to one end of the movable plate 210 so as to be rotatable in the vertical direction. The horizontal rotation movement of the light transmitter/receiver 206 for optical space transmission with respect to the bottom plate 201 is controlled by the bottom plate 201.
The support rod 213 fixed to the mounting bracket 202 by screws 211 and washers 212 is attached to the mounting bracket 202.
The dials 215 and 216 fixed to the mounting bracket 202 are rotated as needed to press the free end of the support rod 213 with the tips of the dials 215 and 216. 2
This was done by rotating the 02 in the left and right direction. The vertical rotation movement of the light transmitter/receiver 206 for optical space transmission with respect to the mounting bracket 202 is achieved by inserting a guide pin 217 fixed to the other end of the movable plate 210 into a guide slot 218 formed in the mounting bracket 202. Then, by appropriately rotating the dial 222 holding the shaft 221 on the fixed plate 220 fixed to the mounting bracket 202 with screws 219, the movable plate 210 is moved along the guide slot 218 with its free end. This is accomplished by vertically rotating the movable plate 210 around the guide pin 217 and, in turn, vertically rotating the light transmitter/receiver 206 around the screw 208.

However, in this case, due to the gap provided between the bottom plate 201 and the mounting bracket 202 to facilitate the horizontal angle adjustment operation, the mounting bracket 202 and the light transmitter/receiver 206 for optical space transmission are not connected to the bottom plate 201. The drawback was that it could not be held stably. In addition, since the guide slot 218 is bored in the mounting bracket 202 and guides the movable plate 201, the mounting bracket 202
In contrast to No. 2, there was a drawback that the movable plate 210 and, by extension, the optical transmitter/receiver 206 for spatial optical transmission could not be stably held.
Therefore, the conventional angle adjusting device of this type has the disadvantage that the optical axis cannot be stably maintained due to external vibrations and the like.

[Purpose of the invention] The present invention was made in view of the above-mentioned circumstances, and its purpose is to create a light transmitter and receiver for optical spatial transmission that can be used for angle adjustment in a short time and can be used stably over a long period of time. An object of the present invention is to provide a device for adjusting the angle of a vessel.

45 in a desired direction. As a result, the position of the variable fitting 41 relative to the screw shaft 36 is varied. When the variable fitting 41 moves, the screw 5
The front piece 46 and the rear piece 47 of the mounting bracket 17, which are connected by 0 and 51, are rotated about the shaft 19.

As described above, the mounting bracket 17 has been rotated in the vertical direction with respect to the fixture 1, so the optical space transmission transmitter/receiver 22 has been rotated in the vertical direction with respect to the fixture 1 as desired. This means that the angle has been adjusted in the vertical direction.
