A weight 10 is fixed to maintain balance with the movable metal fitting 5 and the camera 9 provided on the sliding metal fitting, forming a suspension mechanism type.
A horizontal arm 11 is disposed on the sliding fitting 5 so as to be slidable in a direction perpendicular to the support column 4.
A camera 9 is mounted on an L-shaped camera mount 12 attached to one end of the camera 1. A vertically movable fixing handle 13 for locking the sliding bracket 5 in a predetermined position on the column 4 is provided on the sliding bracket 5, and a horizontally movable fixing handle 14 for locking the horizontal arm 11 in a predetermined position is also provided on the sliding bracket 5. Moving metal fittings 5
It is set in.

Reference numeral 15 designates an external mirror, which is configured to refract the body temperature (infrared rays) of a person sleeping below the mirror 15 in a direction substantially perpendicular to the camera 9 to take an image.

An enlarged view of part A of the camera mounting base 12 in FIG. 4 is shown in FIGS. 5 and 6. FIG. 5 is a plan view of the pan head 16 on which the camera 9 is placed.
is formed into a substantially circular shape, and a through hole 17 is bored in the center thereof, so that the distal end screw portion 20 of the camera fixing screw 18 is inserted into the through hole 17 and projects. The camera fixing screw 18 consists of a knurled knob 21, a shaft-shaped intermediate portion 19, and a screw portion 20 formed at the tip of the intermediate portion 19, and is attached to the center of the camera mounting board 22 formed in a substantially circular shape. The intermediate part 19 of the camera fixing screw 18 is inserted into the drilled through hole 23, and the collar ring 24 is fixed at a predetermined position of the intermediate part 19 to prevent the camera fixing screw from falling off from the camera mounting base board 22. A circle of a predetermined size is drawn from the center of the through holes 17 and 23 at the center of the camera mount base 16 and the camera mount base plate 22, and through holes 25 and 26 are formed at positions that divide this circle into two. ，
27 are inserted and fixed into the through holes 26, 26 of the camera mount base plate 22 with nuts 28, 28 and 29, 29, and the tips of the screws 27, 27 are inserted and fixed into the through holes 25 of the camera platform base 16. Furthermore, camera mounting base board 2
A tap hole 30 is formed at a position where a circle of a predetermined radius drawn from the center of the through hole 23 is divided into four equal parts, and the screws 31, 31, 31, 31 are inserted into the tap hole 3.
0, 30, 30, 30, these screws 3
1, 31, 31, 31 are in contact with the bottom of the camera mount base 16, and the screws 31, 31, 31, 31 are attached to the camera mounting base board 2 using nuts 33, 33, 33, 33.
It is designed to be fixed at 2.

With the above-described configuration, the camera 9 is placed on the camera platform 16, and the threaded portion 20 of the camera fixing screw 18 is screwed into the female screw provided on the bottom of the camera 9.
Fix it on top. In order to make it level in this state, for example, loosen the nuts 28, 28 of the screws 27, 27 while keeping the tips of the screws 31, 31, 31, 31 spaced apart so that they do not come into contact with the bottom of the pan head base 16. Move the pedestal 16 in the direction of arrow B, and then screw the screws 31,
31, 31, 31 to the right, screw 3
The tips of 1, 31, 31, and 31 come into contact with the bottom of the pan head 16, and the pan head 16 moves in the direction of arrow c, so repeat these fine adjustments to horizontally position the nuts 29, 29. ,33,3
3, 33, and 33 were tightened to fix it.

[Problem to be solved by the invention] According to the camera mount shown in FIGS. 5 and 6 above, the screws 27, 27 and the fine adjustment screw 31,
31, 31, and 31 are extended from each other (horizontal adjustment is done by monitoring the camera output status), it takes a long time to perform horizontal positioning. It was time consuming and cumbersome as it required a screwdriver and nut turning. Particularly when measuring the surface temperature distribution of a human body using the camera 9, if the camera 9 is not mounted horizontally on the pan head 16, the problem arises that the image is distorted and accurate temperature measurement cannot be performed.

The present invention was developed in view of the above-mentioned drawbacks, and its purpose is to level the camera 9 extremely easily and quickly, so that the surface temperature distribution of the human body can be measured without distortion as a thermal image. This allows accurate data to be obtained quickly.

[Means to solve the problem]

An example of the horizontal positioning device for a camera according to the present invention has a camera fixing screw 18 loosely fitted in the center of a camera mount board 22, as shown in FIGS. An adjustment knob 37 is attached to a screw 35 inserted into a through hole 38 drilled at a position where a circle of a predetermined diameter centered at a predetermined position of the mounting board 22 is divided into thirds.
and the fixing knob 34 are screwed together so as to sandwich the camera mount base plate 22, and the tip of the screw 35 is fixed to the pan head seat 16, and the camera fixing screw 18 is inserted through the through hole 17 made in the pan head base 16. The tip is made to protrude above the pan head seat 16.

[Effect]

The camera horizontal positioning device of the present invention can easily adjust the horizontal position of the pan head 16 without using any tools by loosening the three fixing knobs 34 and turning the three adjusting knobs 37.

Figure 1 shows an enlarged view of section A in Figure 4.
The camera mounting base board 22 is formed into a substantially disc shape, and the middle part 19 of the camera fixing screw 18 is inserted into the through hole 41 bored in the center of the disc-shaped camera mounting base board 22. Ring-like tsuba ring 24
to prevent the camera fixing screw 18 from coming off from the through hole 41. Drill a through hole 38 at a position dividing the circumference of the camera mounting base board 22 by a predetermined radius into three equal parts, insert the screws 35, 35, 35, and use the fixing knob 34 and adjustment knob 37 to tighten the camera mounting base board. 22, and screws 35, 35,
The fixed knob 34 and the adjustment knob 37, which are fixed to the bottom surface of the pan head base 16, have seats 39, 36 with a diameter smaller than the diameter of the knob, respectively, and screws 35, 35, 3
A flange ring 40 such as an E-ring is fitted to the lower end of 5 to prevent the fixed knob 34 from coming off the screws 35, 35, 35. The pan head base 16 is also formed approximately in the shape of a disk, and a through hole 17 is bored in the center through which the screw 20 of the camera fixing screw 18 is inserted.
The tips of the screws 35, 35, 35 are fixed to the bottom surface of the screws 35, 35, 35 at three equal positions on the same circumference where the screws 35, 35, 35 are arranged.

As mentioned above, the pan head base 16 is supported at three points to maintain the horizontal position, and the tilt angle α can be adjusted by loosening the fixed knobs 34, 34, 34 and finely adjusting the adjustment knobs 37, 37, 37. It can be moved back and forth by 3 degrees.

In this example, the camera can be easily leveled by just finely adjusting the adjustment knobs 37, 37, and 37 without the need for a screwdriver or turning a nut, so the distortion can be avoided by measuring the surface temperature distribution of the human body using an infrared temperature measuring device. It is possible to accurately obtain thermal images that are

Incidentally, the present invention is not limited to the embodiments described above, and various modifications can be made without departing from the gist of the present invention.
