The front view, and FIG. 3 are cross-sectional views of the solid-state CCD / CM camera with a focus adjustment ring taken along line a-a in FIG. 1. ^

Referring to FIG. 1 to FIG. 3, a solid-state CCD / CM camera camera 10 has a body 12; an imaging plate 14 which is disposed inside the body 12 and has a function of capturing images. A CCD / CM0s element; a glass plate 16 which is arranged in front of the camera plate 14 to protect the camera plate 14; a barrel 18 which is arranged in front of the glass plate 16 and It has a lens 18a, a diaphragm 18b, and a filter 18c, which can be rotated in the body to move forward and backward in this way, and a focus adjusting ring 20, which is firmly set at The front end of the lens barrel 18 is rotated together with the lens barrel 18 during the forward and backward movement of the lens barrel 8. The transverse section of the body 12 is generally rectangular, and a cylindrical hole in which the lens barrel 8 is mounted is formed in the long axis direction of the rectangle of the body 12. In addition, the body 12 has a cavity, and the width and height of the cavity viewed from the rear of the body 12 are equal to the inner diameter of the focus adjustment ring 20. The chamber is surrounded by the two side walls, the bottom and top surfaces of the body 12, the rear wall and the glass plate 16. A first step portion is formed inside the body 12 ′ from the back surface of the body 12 at a predetermined length and is molded into a circular cross section. A cavity is formed by the inner shape of the first step, the camera plate 4 and the filter 18c of the lens barrel. The incident light passing through the lens 18b and the filter 18c of the lens barrel 18 passes through the chamber, and finally passes through the protective glass plate 16 and reaches the imaging plate 14. In addition, a second step portion is adjacent

5152-3444-PF-ptd Page 7 587192 V. Description of the invention (5) The first stepped part is formed. The inner space of this second stepped portion is shaped as a thread. The lens barrel 18 is combined with the second stepped portion by a threaded joint, and the lens barrel 8 can be rotatably moved forward and backward. In front of the body 12, a third step

Portion) is formed inside the second stepped portion in the shape of a cylindrical cross section. The lens barrel 18 with the focal length adjustment ring 20 mounted on the front end is combined with the third stepped portion. An arc-shaped guide groove 12a is formed on the front face of the main body 12 to guide the stopper portion 24 of the focus adjustment ring 20, and the curvature of the guide groove is the same as the curvature of the focus adjustment ring 20. The cylindrical lens barrel 18 includes a cylindrical portion (cyUndrical Portion), which has a focusing lens (focusing, a diaphragm 18b, and a filter 18c); a front end portion ("to 10n"), It has one end on both sides of the cylindrical part and the cylindrical part body, and is equipped with a focal length adjustment ring 20. The outer radius of the front end is longer than the outer radius of the cylindrical part. The front part of the tube 18 has a plurality of circular cross-sections = 1¾ ladder 'its radius decreases from the outer peripheral part of the front part toward the body: the axis. The peripheral part of the front end of the lens tube 18 has a sawtooth shape to ensure and focus adjustment The ring 20 is firmly connected. Inside the cylindrical portion of the tube 18, from the front end of the lens tube 18 in order: the installer-focal lens 18a, -aperture 18b, and a filter 18. Focus Ti, 'to light Focus on the camera plate 14, and the aperture 18b adjusts the amount of light emitted by the person entering the body 12 through the lens barrel 18. The light beam i8c directs infrared light from 587192

The incident light is filtered out. As shown in FIG. 4, the focal length adjustment ring 20 includes an adjustment protrusion (Udjusting knob) 22 that lengthens a predetermined length by increasing the diameter of the ring from any point on the outer side of the focal length adjustment ring. The protruding object has a protruded stopper with angular deviation from several angles. The focus adjustment ring 20 has a sawtooth edge on its inner side, similar to the front end of a lens barrel. The joint of the focal length adjustment ring 20 on the peripheral part of the front end of the lens barrel 18 is formed so firmly by this serrated edge ', so that the lens barrel rotates together with this focal length adjustment ring. After the lens barrel 18 equipped with the focus adjustment ring 20 is combined with the main body ，, a stopper 24 protruding from the focus adjustment ring fastens one end of the guide groove 12a. ... When the lens barrel 18 on which the focus adjustment ring 20 is installed is combined with the main body 12, the lens barrel 18 moves forward or backward according to the clockwise rotation or counterclockwise rotation of the focus adjustment ring 20 in the body & The stopper 24 of the focus adjustment ring 20 limits the rotation angle within a predetermined angle range, such as 55. . In the following description, the solid-state CCD / CM0S camera 10 has a dual focus function and can focus at short distances or at long distances. Therefore, the Guping CCD / CM0S camera 10 can focus on both close-range objects with a focal distance within the range of 0 to “㈣g, and also on distant objects with a focal distance of super infinity. ^ First, when When a close-range object is focused, the focus adjustment ring 20 which is firmly set with the front end of the lens barrel 18 rotates clockwise, so that the lens barrel 18 is moved toward the glass plate 16 in the body 12. On the contrary, when it is for a distant object, When focusing, this focus adjustment ring 20 is counterclockwise: move, '587192 V. Description of the invention (7) Causes the lens barrel 18 to be free at this time, and the predetermined angle from the limit range of the stop of the lens barrel 1820 is determined according to this The clockwise rotation is simple and quick, and it can be changed and retouched. The glass plate 16 in the body 12 defined by the range of interest can be moved away from the ground. With the focus lens 18a and the glass plate 6 : Range. 4 keeps the moving range, and the focal length c guide slot 12a moves only within a full degree of dryness. The focal length of the CCD / CMOS camera installed on the front end of the lens barrel through the upturn; Two sides = one advantage to obtain accurate focal length. ° = spirit and range 'For familiarity with this technology 2 clear: solid-state CCD / CM0S camera to do all kinds of = = The scope of protection of the present invention will be attached as the attached Apply for
