[Prior technology] As early as the ancient Greek era, Aristotle has found that in a dense, box opened a small 1, when light penetrates this small hole, it will be on the inner wall of the box fj-and the outside scene of the box The opposite image. After this concept arrived, I began to develop a pinhole observation device (Pinhole 〇bscura), and used to observe the sun. Until the eighteenth century, #people began to close the: pig closed: the wall surface of the body that receives light to generate images, and replaced it with a photosensitive surface to produce the predecessor of modern cameras. The second-stage camera, also known as a pinhole camera (pinhoiie a = ra), does not use any lenses, so there is no focus problem. Generally speaking, the size of the pinhole camera's pinhole (Pinhole) aperture size is affected, and the larger the aperture size is, the clearer the image becomes. However, as the aperture shrinks, in addition to the diffraction effect γ Γ gradually increasing the impact on imaging, due to the large amount of light from the camera film, all the photosensitivity required for the film has disappeared in the commercial market.

The lens has at least one second opening 204 on the side wall of the cabinet 200 in 2001. The section is horizontally placed with the device 220 through this second opening 204. In the cabinet 200, a focal length test piece 250 is carried, and 彳 Θ, 1 ^ of the focal length test piece 2 500 is vertically aligned with the lens 24. The light source 230 is installed in the cabinet 20 η Μ inner surface 200C, so that the light generated by the light source 230 can pass through the focal length test chart to the lens 240, thereby carrying the test image on the focal length test piece 250 to the lens to be tested 240. In order to make the focal length test piece The replacement of 2 5 0 is convenient, even if the test film contains m Γ to move smoothly. 'Please refer to the fourth picture, which is an enlarged display of the second ^ The opening 204, and the corresponding relationship between the test piece carrier 220 and the second opening. As shown in the figure, a horizontal slide groove 208 is made on the inner surface of the side wall 200b adjacent to the second opening 204, and the test piece carrier A bearing plate 222 having a one-two-two-two-focus? Test piece 250. This bearing plate 222 moves the smoothing groove 208 to drive the carried focal length test piece 250, and ensures that the focal length test piece 250 is accurate. Inside the cabinet 200. Beyond the door, the door is next. In order to facilitate the user to change the focal length test piece 25, please refer to the five pictures, and add a long handle 224 on the side of the load plate 222. It is worth noting that the size of this long handle 224 is larger than the second opening 204 = size. Therefore, when the carrying plate 222 is put into the box through the horizontal slide slot 208, the long handle 224 is still blocked in The outer side of the second opening 204 is convenient for the user to pull out the test piece carrier 220.

At the periphery of the above-mentioned bearing plate 222, a birch frame 226 surrounds the focal length test piece 25 °, and the outer portion is added. It is worthwhile to set up β to maintain the focal length of the test piece 250. The position of the test piece 250 must be smaller than the second opening 204 (please refer to the size of "26", 220 must pass through -η σ $? Η4 in the figure) to ensure the test. On-chip. From the first opening 204, a focal length test piece 25 is placed in the case 20. In order to make the replacement of the lens 240 under test more convenient, as an example, please refer to the seventh figure. This is a good knowledge of Jian Jianhua -t ^, ^ 300 ^ points: 待: lens 24 °, through The movable lens holder is 300a in the top of a plurality of cabinets within 300. As shown in the figure, in this cabinet, parallel sliding grooves 306 'are formed on the inner surface of the two opposite side walls 300b near the upper edge. The opposite two sides of the top 300a of the box are fitted in a parallel sliding groove 306. Therefore, the top 300a of the box can be pulled apart from the other parts of the box 300 (along the top indicated by the arrow in the figure) H. Change ... When detecting the focus of the lens, you can directly change the detected lens by changing the cabinet and W 300a. In order to prevent the external light source from disturbing the ongoing focus detection inside the cabinet 'The box system of this creative focus detection box is made of opaque materials2, such as wood, metal, etc. In addition, in order to make the focal length test pieces placed at different positions of the box 2, you can get light with similar intensity, Referring to the third figure, for a preferred embodiment, the box Light source within 2000.

The upper edge of the inner surface of 20Ob extends to the lower edge. In order to provide users with greater flexibility, please refer to the eighth figure. The bottom of the box of this focus detection box is 20 (the device has three rollers 26, and at the same time, The outer surface of the side wall of the box body 200 d is also made with a plurality of cushions 270 to facilitate the focus test box lying on the work platform side. It is worth noting that the side wall 200 d is relative to the production of The side wall 2OOb of the second opening 2 04. From this, it can be seen that, in addition to being easy to move, the focus detection box of this creation can also be used to perform focus detection in the vertical or horizontal direction in accordance with the needs of the user. The focus detection box is aimed at a small camera lens, and at the same time focuses on the mobility of the focus detection box. Therefore, in a preferred embodiment, the height of the test box is between 50 cm and 80 cm. To take into account the focal length detection distance and the test box In addition, in order to provide a commonly used focal distance test distance, in a preferred embodiment, as shown in Figure 9, three side openings 204a, 204b and 204c, has a vertical distance of 20 cm, 50 cm, and 60 cm from the lens 120 fixed in the first opening 202, respectively. It is worth noting that the number and position of the second opening can be determined according to actual needs. Examples Explanation ·· If the lens to be measured has a close-up distance of 5 cm, a second opening 2 should be provided on the side wall of the focus detection box 2 0 0 b and a vertical distance of 5 cm from the lens in the first opening. 0 4. If the design of the lens to be tested 'is considered to be infinity from an image with a distance of more than 60 cm, a vertical opening of 60 cm from the lens in the first opening on the side wall 20Ob of the focus detection box should be provided with a second opening 2 0 4. M253796 IV. Creation Instructions (8) Compared with the traditional focus detection system, the focus detection box of this creation has the following advantages: 1. As shown in the eighth figure, the size of the focus detection box of this creation is small. A roller 260 is provided at the bottom of the 200 and a cushion 27 is provided at the side wall. Therefore, in addition to facilitating the user to move according to requirements, the focusing test box is also conveniently placed horizontally, which can provide greater flexibility in use. For the sake of harmony, this work creates a horizontal chute 208 on the side f adjacent to the second opening 204 to ensure that the test piece stage 220 is in the horizontal direction: Fang: '奂 In other words, also ensure that the focal length test piece 250 must be vertical 20% at the time of the mirror: The traditional focus detection system used to adjust the focus test piece is required. II: As shown, the focus detection box of this creation is based on three routines; the focus test piece 250 is placed in these The second opening process. χ The test embodiment of the traditional focal length detection system can be interspersed.
