ため取付場所が限定されてしまうということがあった。[Background technology 1 Heat-ray detectors are passive type, so they do not require a light-emitting part, so those that can three-dimensionally detect a wide detection area are the mainstream. . In order to perform three-dimensional warning in this way, the structure of the entire device becomes complicated and large. For this reason, attempts have been made to reduce the size by using a 7-Renel lens, but there are limits to miniaturization. On the other hand, in order to make it smaller, 1
A beam type hot wire detector has also been developed, but it can be changed by adjusting the mounting direction and area. This meant that the installation locations were limited.

される。In this embodiment, a heat ray detection element 1 is used that has no detection directionality, that is, there is no direction in which heat rays cannot be detected. This heat ray detection element 1 and an amplifier circuit for amplifying the output of the heat ray detection element 1 are mounted on a printed circuit board 5, and this printed circuit board 5 is formed into a storage body 6 which is approximately spherical and has an opening window 7 at the top.
The heat ray detection element 1 is housed in the housing so that the detection surface of the element 1 faces the Sekiguchi direction. A seven-lens lens 8 is attached to the opening window 7 of the storage body 6, and the periphery of the opening window 7 forms a stopper 19 that projects outward to prevent the storage body 6 from rotating more than necessary. be. At the bottom of this storage body 6 is a draw-out hole 1 from which an output m9 connected to the amplification circuit output etc. is drawn out.
0 is perforated. This storage body 6 is stored within the body 11.

ようにいである。This body 11 has a cylindrical shape, and its surrounding wall is narrowed upwardly so that the upper circular opening has a smaller diameter than the diameter of the storage body 6. When the storage body 6 is stored from below inside the body 11, the opening window 7 at the top of the storage body 6 is opened.
Even if the side is exposed to the outside, the storage body 6 is prevented from jumping out to the outside.

やがたつきを防止している。A bottom cover 12 is attached to the lower opening of the body 11. In order to attach the bottom cover 12 to the body 11 without screws, two protrusions 21 are provided at multiple locations on the inner surface of the body 11 so as to protrude inwardly along the circumferential direction. The thickness is approximately equal to the thickness of the cover 12. Therefore, the bottom cover 12 can be attached to the body 6 without screws by fitting the bottom cover 12 between the protrusions 21 using the recesses on the peripheral edge of the bottom cover 12. Incidentally, claws 23 are formed on the peripheral edge of the upper surface of the bottom cover 12, and the claws 23 become higher in the circumferential direction. This prevents it from coming off or rattling.

しである。A plurality of flexible cylindrical spring bodies 13 are provided upwardly on the bottom cover 12, and these spring bodies 13 are provided on the same circumference of the top surface of the bottom cover 12. Further, the upper end of the spring body 13 has its tip formed obliquely toward the center of the bottom cover 12 so as to increase the area in contact with the outer surface of the storage body 6. The terminal 14 to which is connected is the attachment. This spring body 13
When the storage body 6 is inserted into the body 11 and the bottom cover 12 is attached to the body 11, it bends as shown by the broken line in FIG. 3, and this elasticity pushes the storage body 6 upward. , the storage body 6 is pressed into contact with the upper opening of the body 11 and fixed so as not to rotate. If force is applied to the storage body 6, it can be rotated about the axis of the body 11 against the elastic force of the spring body 13, or it can be made to swing in the front, back, left and right directions. At this time, the above-mentioned stopper 19 comes into contact with the periphery of the opening of the body 11 to prevent the storage object 6 from entering the opening of the body 11, thereby preventing the storage object 6 from rotating too much. Furthermore, a heat and wire type detector is installed on the wall surface 1 at the bottom of this body 11.
A base 15 attached to the body 11 is attached to the body 11. The base 15 has a bottomed cylindrical shape with an open upper surface, and is provided at a plurality of locations along the side surface with horizontal pieces of mounting pieces 24 having a cross section facing outward. And body 1
A locking protrusion 22 that protrudes inward is formed on the periphery of the opening of 1, and by locking the horizontal piece of the mounting piece 24 to this locking protrusion 22, the base 15 and body 11 can also be attached without screws. It is now possible to The bottom plate of the base 15 is formed with a screw hole 16 for fixing the base 15 to a wall surface 18 with a screw 20, and a pull-out hole 17 or knockout for pulling out the wiring connected to the terminal 14 outside the device.

Fig. plS2 shows a state in which the heat wire detector is fitted into the lower opening and the assembled heat wire detector is attached to the base 15 attached to the wall surface 18. In this state, hold the exposed part of the body 11 of the heat-ray detector housing 6 from the 1JrI opening and rotate the housing 6 around the sleeve of the body 11 or left and right as shown by the arrow A and the mouth in the figure. The direction in which the hot-wire detector detects the human body can be changed by freely swinging it up and down.Therefore, there are no restrictions on the installation location of the hot-wire detector.Moreover, in this embodiment, the bottom cover 12
Since the base 15 can be attached to the body 11 without screws, the attachment is easy and the number of parts can be reduced.
