New Description: [New Technology Field] This creation is about an image capture device suitable for machine vision systems, especially an image capture device with a frame between the lens and the image capture unit. [Prior Art] Press 'The machine vision system includes Image Sensor, Analog/Digital Converter (A/D Converter), and Computer. The image capturing device is configured to capture an image of an object, such as an electronic component or a printed matter, to generate an analog image. The analog/digital converter is used to convert the analog image data into a digital image data for processing by the computer processor and stored in the storage device. The computer can be controlled by the software to control the operation of the machine vision system, including a series of processing steps such as image acquisition, analysis, and data transfer. The image capturing device applied to the foregoing machine vision system generally uses the light provided by the light source to project onto an object, and the object reflects the light to generate a scene with the material on the object, and forms an incident light. After an angle is incident on the lens, it is imaged in the image capturing unit. In fact, the working distances between objects and image capture devices vary from one environment to another. Therefore, in order to effectively shorten the working distance, a plurality of mirrors are disposed in the image capturing device, and under the existing mirror and the lens, and the number of reflections of the mirror and the magnification of the lens are not changed, the incident is made. The light can be clearly and completely imaged in the image capturing unit, and the position of the image capturing unit must be relatively adjusted with the length of the working distance to obtain an appropriate total optical path length. Therefore, in view of the above shortcomings, it is necessary to develop an image capturing device for improving the machine vision system to meet market demands. 4 [New content] / In order to solve the above problems, one of the purposes of this creation is to provide an image capture «, in order to change the work _, the length in the direction of the shadow _ shot ^ lead line, in order to make a red _ Head and image age unit _ Mi Lin. In order to achieve the above-mentioned purpose, the image adjustment device of the age-adjusting mirror is provided with at least a mirror and a lens, and the body of the body disk has a Na to the bribe, the thief Wei reflected at least one, _ owed, and then passed to the mirror Caiqi Jiao. The light-making hobby includes a framed image image unit, and the frame-touch is placed on the lens. The other side is disposed on the shadow side taking unit, and the image is separated from the image-like image. After the lens is applied to the lens and the imaging distance is transmitted, it is imaged on the Na unit, and the surface is relatively adjusted along the working distance in the light-directing direction. Further considerations [Embodiment] The above object of the present invention, its structure and the structure of Wei, will be explained in accordance with various embodiments of the drawings. FIG. 1 is a schematic diagram of image capture of an embodiment of a creative image capture device. As shown in FIG. J, the image capturing device (10) of the present invention comprises a light source (11), a body (15) and a light sensing module (19). The body (15) includes a mirror group (13) and a lens (17). The light source (11) is used to provide light to the object (12), and the object (12) reflects light to produce light with an image of the object (12). The mirror group (3) includes at least one mirror for receiving light reflected from the object (12), the light is reflected at least once between the mirrors, and then transmitted to the lens (17) for focusing. Each of the mirrors in the mirror group (13) has no limitation on the placement position, the order of light reflection, or the number of times of light reflection, as long as it is placed on the optical path where the light can be accurately reflected, but each mirror is The placement angle must vary with the placement of the individual lenses, the order in which the light is reflected, or the number of times the light is reflected. As illustrated in Figure i, the mirror group (13) is arranged in a counterclockwise direction as a first mirror (131) and a second mirror (133). The light source (n) projects light toward the object (12), and the object (丨2) reflects the light to produce an image with the material on the object (12) and forms an incident light incident from the angle to the first mirror. (131). Then, the light is sequentially reflected by the first mirror (131) and the second mirror (133), and then emitted from another angle, and after being focused by the lens (17), is imaged in the light sensing module (19). ). In one example, the light sensing module (19) includes a frame body (192) and an image capturing unit (191), and the image capturing unit (19i) includes a photosensitive wafer (191a) and a photosensitive substrate (191b), and The photosensitive wafer (i91a) is fixed on the photosensitive substrate (191b). For example, the image capturing unit may be at least one of a Charged Coupled Device (CCD) or a Complementary Metal-Oxide-Semiconductor (CMOS). In this embodiment, the light source (丨i) is disposed outside the body (15), and the light sensing module (19) is disposed in the body (15), but the creation is not limited thereto. For example, the light source (11) can be located in the body (I5), and the light sensing module (19) can be located outside the body (15), but the photosensitive wafer (191a) and the photosensitive substrate (191b) must be located in the optical path. on. As shown in FIG. 1, a light source (Η) is disposed outside the body (15), and the light source (11) is located on a path through which the object (12) reflects light to the first mirror (131). The light required to capture the image of the object (12). The light sensing module (19) is located within the body (15). When the object (12) and the image capturing device (10) are separated by a working distance d, 'the light can be reflected by the reflection between the mirrors and then transmitted to the lens (π) to focus, but if the mirror is placed There is an error in the position, and the magnification can be automatically adjusted by the lens (17) and the focus is automatically fine-tuned. The light sensing module (19) includes a frame (192) and an image capturing unit (191). One side of the frame body (192) is disposed on the lens (17) and the other side is disposed on the image capturing unit (191), and an imaging distance is provided between the lens (17) and the image capturing unit (191). M378586 from g. After the light is focused on the lens (17) and the imaging distance g is transmitted, it is imaged on the image capturing unit (191). According to the above, the length of the frame (192) in the light transmission direction is the imaging distance g between the lens (17) and the image capturing unit (191). Moreover, the imaging distance g between the lens (Π) and the image capturing unit (191) is relatively adjusted with the working distance d.

As shown in FIG. 2, when the distance between the object (12) and the image capturing device (10) is shortened to the working distance d1, the light is sequentially reflected through the first mirror (131) and the second mirror (133). After reaching an optical path length, it is transmitted to the lens (17) for focusing. At this time, the user can increase the length of the frame (192) along the direction of the light transmission by the number of the existing reflections, the number of reflections, and the lens magnification, so that the lens (Π) to the image capturing unit (191) The imaging distance g is increased relative to the working distance dl to the imaging distance gi, thereby obtaining a clear and complete image. Figure 3 is not a different example of the creation according to this creation. As shown in FIG. 3, when the distance between the image capturing device (10) of the object (12) increases to a working distance ,, the light sequentially passes through the 'first mirror (131) and the second mirror (133). After reflecting to an optical path length, it will focus on the lens (17). At this time, the user can reduce the length of the frame (192) along the light transmission direction by the number of existing mirrors, the inverse number of times, and the lens magnification, so that the lens (17) to the image capturing unit (191) The imaging distance g is shortened to the imaging distance g2 with respect to the working distance d2, thereby obtaining a clear and complete image.
