があった。[Background Art 1] Conventionally, this type of infrared detection device that detects infrared rays from a plurality of detection areas has a concave mirror 10 corresponding to each of the plurality of detection areas, as shown in FIG. There is one in which a condensing means 1 is formed to condense infrared rays from each detection area to one point, and an infrared detecting element 2 is provided at the condensing point of the condensing means 1. By the way, in this conventional example, the infrared detecting element 2 is attached to the mounting plate 11 which is rotatable in the direction of arrow A, the light emitting diode 3 is attached to the back surface of the mounting plate 11, and the mounting plate 11 is operated. By rotating the knob l1m by 180 degrees, the light emitting diode 3 is placed at the condensing point of the condensing means 1.
is positioned, the light emitting diode 3 is turned on, and the light from the light emitting diode 3 is projected onto each detection area via the condensing means 1 to confirm the detection area. However, such a conventional detection area confirmation means has a problem in that the rotation mechanism of the mounting plate 10 becomes complicated and the cost increases. Therefore, Figures 8 and 9
As shown in the figure, when using a condensing means 1 consisting of a plurality (2X 4 ) of 7-lens lenses 12, an infrared detecting element 2 and a light emitting diode 3 are arranged on the same surface of the mounting plate 11, and a lower 7-lens lens 12 is used. By projecting the light of the light emitting diode 3 through the Lennel lens 12 (indicated by the dotted line in the figure), the detection area corresponding to the upper 7 Lennel lenses 12 can be confirmed without rotating the mounting plate 11. However, in such conventional cases,
Although the configuration is simplified, there is an inconvenience that the detection area corresponding to the lower 7-lens lens 12 cannot be confirmed. Therefore, as shown in FIGS. 10 and 11, each 7
There was a system in which a detection area confirmation lens 12a was added to the Lens lens 12, and the light from the light emitting diode 3 was projected onto each detection area via this detection area confirmation lens 12a. There is a problem that the effective area of the infrared detection part decreases, resulting in poor detection sensitivity.Also, since the detection area confirmation lens 12a cannot be made too large, the beam projected by the light emitting diode 3 becomes narrower and the amount of light decreases. Therefore, if the detection area is far away, there is a problem in that it becomes difficult to confirm the detection area.

In an infrared detection device similar to the conventional example, a light receiving area is A light emitting diode 3 with a small area is also installed, and when checking the detection area, the light emitting diode 3 is
The light emitting diode 3 is turned on to emit light of 1/3 to each detection area via the condensing means 1. In the embodiment, the light emitting diode 3 is protruded from the mounting plate 11. It is attached to the tip of the L-shaped support 4. Note that the reduction in detection sensitivity due to light shielding by the light emitting diode 3 will hardly be a problem if the area of the light emitting diode 3 is made smaller than the light receiving area of the infrared detection element 2. Alternatively, the light emitting diode 3 may be rotatably attached to the infrared sensing element 2, and the light emitting diode 3 may be positioned on the light receiving surface of the infrared sensing element 2 only when confirming the detection area.

ている。Now, since the infrared detection element 2 and the light emitting diode 3 can be considered to be at approximately the same optical position with respect to the condensing means 1,
When the light-emitting diode 3 is turned on, the light from the light-emitting diode 3 is projected onto each detection area through each of the seven Lennel lenses 12 of the condensing means 1, and the detection area can be easily confirmed by the projected light. is now possible. In this case, since the detection light condenser Fi1 is also used as the confirmation light projection means, the configuration is simplified, and the confirmation light projection means can be of a large area equivalent to the light condensing means. It is possible to reliably check each detection area of the light projection.

In the device, a light-emitting diode with an area smaller than the light-receiving area is attached to the light-receiving surface of the infrared detection element, and when the detection area is confirmed, the light-emitting diode is turned on and the light from the light-emitting diode is directed to each detection area via a condensing means. The device is designed to emit light, and the condensing means for infrared detection is also used as the light emitting means for confirming the detection area, so the configuration is simple and the cost is low (and the light emitting means for confirmation is also used). Since it is possible to use a means having a large area equivalent to that of the condensing means, there is an effect that each detection area of light projection can be reliably confirmed.
