ている。[Embodiment of the invention] An embodiment of the invention will be described below with reference to the drawings. In the drawings, reference numeral 11 denotes a cylindrical lens hood, for example, and a lens mounting portion 12 is provided on the front surface of this lens hood 11.
4 is fixed. A shield case attachment part 15 is provided inside the rear part of the lens hood 11,
A shield case 16 is slidable in the front and rear directions within this shield case mounting portion 15. Note that the optical axis of the lens 14 and the central axis of the shield case 16 coincide. A light emitting and light receiving element 17 is fixed to the center of the front surface of the shield case 16. The input/output terminals of this light emitting and light receiving element 17 are electrically connected to a printed circuit board 18 attached to the opposite surface of the shield case 16 through a through hole, so that signal processing for transmission and reception is performed. It's getting old. Also, shield case 16
A lid 19 is attached to the rear surface of the housing with screws 20, 20 to keep the interior shielded. At the rear of the lens hood 11, the back cover 21 has screws 22,
It is attached by 22. A screw hole 23 is provided at an upper position away from the center of the back cover 21, and an adjustment screw 25 is inserted through the screw hole 23 via a retaining ring 24 to have its base end attached thereto. The distal end side of the adjustment screw 25 is screwed into a screw hole 26 provided in the lid 19 of the shield case 16. A compression coil spring 27 is wound around the adjustment screw 25 between the back cover 21 and the cover 19.
The elastic force of 7 causes the shield case 16 to close to the lens 1.
It is designed to be pressed in four directions. Further, a screw hole 28 is provided on the lower surface of the lens hood 11, and a set screw 29 is attached to this screw hole 28.

になる。 That is, in this adjustment device, by rotating the adjustment screw 25, the shield case 1
6, that is, the light emitting and light receiving element 17 is moved back and forth. In this case, the shield case 16
moves while being held down by the elastic force of the compression coil spring 27. In addition, since the center axis of the lens hood 11 and the axis of the adjustment screw 25 are misaligned, the lens hood 11 does not rotate at the same time as the adjustment screw 25 rotates, and the shield case 16 slides smoothly. . In this case, if a key groove is formed on the contact surfaces of the shield case 16 and the lens hood 11 to create an uneven structure, the sliding will be made even smoother.

Although a cylindrical case is used as the shield case 16, the present invention is not limited to this, and a rectangular cylinder may also be used. In this case, there is a risk that the shield case 16 may rotate inside the lens hood 11. Since there is no adjustment screw 25, the adjustment screw 25 may be provided on its central axis.
