Abstract

PROBLEM TO BE SOLVED: To prevent a lens from being assembled in vertically inverted posture when assembled into a light shielding cylinder, by engaging a guide recessed part or guide projection provided on the circumference on the lens side with a projection or recessed part provided within the light shielding cylinder. SOLUTION: A guide recessed part 11, for example, is provided in the position of a flat collar part on the circumference of a lens A so that the lens A is not rotated in the front and back direction or vertically, and a linear projection 10 is provided on the inside of a light shielding cylinder 5 corresponding thereto. Since the lens A is fallen into the light shielding cylinder 5 in the state where the guide recessed part 11 is engaged with the linear projection 10, the front and back directional or vertical, rotation of the lens A is arrested. Further, since the tip of a lens nipping tool P such as pincette can be inserted to the inner part of the light shielding cylinder 5 as a recessed part 9 formed on the edge differed by 90 deg. from the guide recessed part 11 on the circumference of the lens A is nipped by the tool P, the front and back or upper and lower surfaces of the lens A are never replaced with each other while it is released from the holding state and falls within the light shielding cylinder 5.

2. Description of the Related Art A conventional infrared light focusing lens fixing mechanism will be described with reference to FIGS. 15, 16 and 17. FIG. FIG.
Discloses a configuration of a conventional lens 13. In the conventional lens 13, the central arc-shaped convex portion 13a and the outer peripheral flat flange portion 13b are formed in a circular shape. Therefore, this circular lens 13 is clamped by a lens clamping tool such as tweezers, and the light-shielding cylinder 19 shown in FIGS.
When trying to insert it inside, the outer circumference of the circular lens 13
Since no space is provided between the light-shielding cylinder 19 and the lens-clamping tool, the holding state by the lens-clamping tool needs to be released at the entrance of the light-shielding cylinder 19. When the lens 13 is released from the holding state by the lens holding tool and the lens 13 is dropped into the light shielding tube 19, FIG.
As shown in FIG.
As shown in FIG. 6, a case where the robot falls in an upside down posture occurs.

When the lens 13 falls, the center of gravity is located on the arc-shaped convex portion 13a, and friction occurs due to contact with the flat flange portion 13b or the inner periphery of the light shielding tube 19. Therefore, the portion of the flat flange portion 13b tends to be delayed, and the portion of the arc-shaped convex portion 13a falls first, so that the erroneous assembly posture in the state of FIG. 16 is likely to occur. An object of the present invention is to solve the problem that the lens is assembled upside down as shown in FIG.

The fixing mechanism of the infrared condenser lens shown in FIGS. 2 to 7 shows an embodiment of an infrared position detecting sensor. In the light-shielding tube case C, light-shielding tubes 4 and 5 on both the light-emitting side and the light-receiving side are formed, and a lens A having a substantially similar configuration is inserted into the light-shielding tube 4 and 5. Because In the light-shielding tube case C of the present embodiment, the axial direction of the light-shielding tubes 4 and 5 and the direction of the front surface of the light-shielding tube case C are not perpendicular to each other. However, the juxtaposed light-shielding tubes 4 and 5 are arranged in parallel directions. Infrared light emitted from light emitting diodes etc.
The light passes through the light-emitting lenses inserted into the light-shielding tubes 4 and 5, and is emitted and emitted in the direction of the measured object. Then, the infrared light irradiated and reflected on the object to be measured returns, is received by the light receiving lens, and is converted into an electronic signal by the light receiving element.

As described above, in the light-shielding tube case C, separate lenses A are inserted into the light-shielding tubes 4 and 5 as a light-receiving lens and a light-receiving lens. They have almost the same shape. The light-shielding cylinder 5 and the light-shielding cylinder 4 are slightly different in the size of a hole in a portion through which infrared light passes. The infrared passage hole of the light shielding tube 4 is larger than the infrared passage hole of the light shielding tube 5. However, the shapes of the holes of the light-shielding cylinders 4 and 5 where the lens A is inserted are configured to be substantially the same.

In the prior art, as described above, the shape of the light-shielding cylinder 19 is also circular, and the lens 13 is also configured to be circular. However, in the present invention, as shown in FIG. Visually, it has a rectangular shape with rounded corners. The light-shielding tubes 4 and 5 of the light-shielding tube case C into which the lens A is inserted are also formed in a rectangular shape with rounded corners. In this way, the possibility of turning in a plane as in the case of the circular light-shielding tube 19 and the circular lens 13 has been eliminated even by simply forming the rectangular shape with rounded corners.

The lens A has a flat flange 8 and an arc-shaped convex 7.
Is configured. The arc-shaped convex portion 7 is a portion that functions to condense infrared rays, and the planar flange portion 8 is a portion for stabilizing the position of the lens A.
In the present invention, a guide recess 11 is further provided at the position of the flat flange portion 8 on the outer periphery of the lens A so that rotation of the lens A does not occur in the front or back or in the vertical direction.
Are provided with linear projections 10 inside the corresponding light-shielding cylinders 4 and 5. In this manner, the linear projection 10 is
5 are arranged at positions opposed to each other by 180 degrees, and two guide recesses 11 are also provided at positions opposed to each other by 180 degrees on the outer periphery of the lens A. Since the lens A falls into the light-shielding tubes 4 and 5 in the state where the guide concave portion 11 and the linear protrusion 10 configured as described above are engaged, the lens A prevents the front and back or vertical rotation. It is done.

Further, the tip of the lens holding tool P such as tweezers is inserted into the outer periphery of the lens A at a position rotated by 90 degrees with respect to the portion where the guide recess 11 is provided. A concave portion 9 is opened at a position 180 degrees opposite to the flat flange portion 8 so that the tip of the holding tool P can be inserted into the light shielding cylinders 4 and 5. As described above, the tip of the lens holding tool P such as tweezers can be inserted into the light shielding tubes 4 and 5 while holding the concave portion 9 by the lens holding tool P such as tweezers. While A is released from the holding state inside the light-shielding tubes 4 and 5 and falls, the front and back surfaces or the upper and lower surfaces are not interchanged.

The infrared type position detecting sensor formed by using the above-mentioned fixing mechanism of the infrared condensing lens can be used as, for example, a human body position detecting sensor S. In FIG. A planar positional relationship between the wall H, the toilet U, and the human body position detection sensor S is illustrated. Usually, it is highly likely that the toilet bowl U is arranged at the center, and the human body position detection sensor S is arranged on a wall portion H such as a toilet on the side surface thereof. Then, in a state where the user is sitting on the toilet U, it is confirmed that the DUT 3 is present at the position, and a certain amount of flush water is allowed to flow 10 seconds after the user sits down. When the user leaves, operations such as flowing of washing water are automatically performed after 3 minutes.

In this case, the human body position detection sensor S may be disposed in front of the low tank W. However, when the toilet lid F of the toilet bowl U is opened, the optical path is not closed by the toilet lid F. It is necessary to arrange the human body position detection sensor S at the position.
