The degree of offset of the set position point. In the past, the line edge sensor system for general corrective use (as shown in the first and second figures) hits the uniform light on one line and waits on the line 5, and then the image of the light area is imaged by the lens combination. A double photosensitive element inside the detector, 171, above the position of the line if it is to the left or to the right, its effect on the photosensitive element 17 〇, and the photosensitive element 171 is in the opposite direction 'and ^ is also linear. Therefore, we can use the two photosensitive elements to connect (4) the size of the letter to the side of the side to offset the set point. However, when the color line is detected by the line and edge sensor manufactured by this spiritual purpose, only a single light source is projected on the substrate paper, and if the color stripe does not reflect the spectral response of the light source, Therefore, we can not obtain a reliable output signal. Therefore, how to solve the problem that such a conventional edge sensor or a line sensor is not sensitive enough to certain marks is a problem to be solved. 5 1286597 • The design of the illuminating source effectively avoids the lack of sensitivity of some of the color markers described above, and proposes the luminous intensity of the two rows of illuminating element groups (LE:D) on the substrate paper. It is a two independent straight-line light source that changes linearly from left to right, and simplifies the receiving unit as a single receiving component. Therefore, the two luminous intensities can be composed of two different linear light sources, which can be composed of different spectral light-emitting elements. The complementary two light sources are dominant, and at least one linear light source will react significantly to any color fringe, thus greatly improving the conventional correcting deviation with the heel sensor. The detection capability of the offset position of the color stripe. The secondary object of the present invention is to provide a double-row illumination source design for a heel-and-edge dual-purpose sensor for correcting the purpose, and to achieve a luminous source with a diamond-shaped aperture shutter. The luminous intensity of the substrate paper can be easily presented in two rows of alternating linear changes in the opposite direction for the dual-purpose inspection of the color printing and the heel and the side. In order to achieve the above and other purposes, the present invention has a corrective use. The double-row illumination source design of the dual-purpose sensor with the line and the edge is suitable for the technical method of monitoring the edge line when the correction of the printing industry is used. The technical method of the dual-purpose sensor is mainly The row of light-emitting elements cooperates with a diamond-shaped aperture shutter as a light-emitting source, and the two rows of light-emitting elements each have an equally spaced number of light-emitting element groups (LE:D) and have the same number of resistors on the back surface of the circuit board The intensity of the light emitted by each of the corresponding light-emitting element groups (LH) is controlled by each resistor to emit light of a small to large intensity as a light source, and the light source After staggered emission through the diamond-shaped aperture shutter, the luminous intensity on the substrate paper arranged at the set sensing distance can be a straight light source that changes linearly from left to right, and then the light source is used on the original substrate. The signals reflected back on the paper are interleaved and synchronized to obtain an analog output to monitor the line on the substrate paper and how far away from the original center point. The two rows of light-emitting elements can be blue and the other row in one row. The complementary yellow light can capture any color mark, or both rows can be white light. The two rows of light-emitting elements are reflected on the substrate paper and returned to the sensor to generate two sets of receiving signals I and Π The line-and-edge dual-purpose sensor can convert the analog circuit as needed, and treat the two sets of received signals I and Π as I; [[ or I + π for the purpose of line detection or heel detection. 6 1286597 In addition, in the present invention, when monitoring the line of the extreme edge, the left and right outermost light sources of each row of light-emitting elements can be turned off to avoid the edge of the substrate paper, and the straight line can be detected. The following is a description of the embodiments of the present invention by way of specific examples, and those skilled in the art can readily understand the other advantages and advantages of the present invention from the disclosure of the present disclosure. The present invention may be implemented or applied by other specific examples. The details of the present specification may also be based on various viewpoints and applications, and various modifications and changes may be made without departing from the spirit of the invention. First of all, please refer to the reviewer, as shown in the third, fourth and fifth, and sixth, the double-row illumination source design of the wire-to-edge dual-purpose sensor for corrective use according to the present invention, wherein: The sensor 1 is mainly composed of two rows of light-emitting element groups (LEDs) 10, 11 and their corresponding two sets of control resistors 12, 13, and two rows of light-emitting element groups (LEDs). The opening shading H 14 constitutes a light source of the dual-purpose sensor ,, the diamond opening shading H 14 + central region has a diamond hole, a hole 14 〇, two rows of light-emitting elements (LED) 10, 11 are equally spaced Five light-emitting elements (LEDs) 1〇〇, 1〇1, 102, 103, 104 and 11〇, (1), 112, 113, 114, via corresponding control resistors 120, 121, 122, 123, 124 and 130, 13 Bu 132, 133, 134 control the intensity of the illumination according to the sort order from strong fade or weak fade; the central region of the dual purpose sensor 1 is inclined at a 45 degree angle with a single beam splitter 15' by the beam splitter 15 The first row of light-emitting element groups (Lm) 1 〇 and the second row of light-emitting element groups pED) 11 can be shielded by diamond-shaped openings The light source emitted by 14 is reflected to the external lens 16 of the dual-purpose sensing f1, and then the light and shadow 3 hitting the substrate paper at the set sensing distance is 2, because it is a two-row light-emitting element group (Lm))丨Interlaced light, so the source of the light source is two groups, and the light shadow 3 on the substrate paper 2 is reflected back to the single receiving unit 17 disposed at the inner rear edge of the dual-purpose sensor 1 to adopt the interlaced synchronization. The receiving party ^ can also receive the corresponding two sets of signals I, Π. Then, please continue to ask your review committee to refer to the seventh, eighth, ninth and tenth, and .1286597. The eleventh figure is shown in the previous figure, and the figure shown in the eighth figure is mainly the flow of the splitter 15 The relationship between the light and shadow 3 and the luminous intensity 4 produced by the light, and the characteristic that the light intensity 4 changes linearly; as shown in the seventh and eighth figures: a heel of the corrective use in the present invention Dual-purpose sensor double-row light source design light and shadow 3 on the substrate paper 2, because two rows of light-emitting element groups (LEDs) 10, 11 can use their two sets of control resistors 12 '13 on the back of the circuit board To set the intensity of the illumination according to the sort order, the strong fade or the weak fade, and the diamond hole 140 opened by the diamond open shutter 14 can control the shape of each light source element to be a diamond shape, the substrate The detection set distance of the paper 2 is the plane of the intersection of the inner edges of adjacent beams in the light beam. When the light source is reflected by the beam splitter and the front lens group, it will be imaged on the substrate paper 2 to obtain two straight rays. Imaging is like light and shadow 3, as shown here The luminous intensity 4 corresponding to the light and shadow 3 may be a straight light source that changes linearly from left to right. For example, if the light source is adjusted to the strongest light source intensity, the light and shadow on the substrate paper 2 is 3-100. The luminous intensity of the generated 4-100 is naturally largest, and the order is the strongest of the illuminating lamp 101, the middle of the illuminating lamp 1 〇 2, the illuminating lamp 1 〇 3 times weak, and the illuminating lamp 104 is the weakest, so the film is sequentially printed on the substrate 2 The luminous intensity of the upper light and shadow is 4—, 4-102, 4-103, 4-104. The apex of the diamond shape is gradually lower. If the luminous intensity of each diamond light and shadow is 4-100, 4-101, 4_102, 4-103, The vertices of 4-104 are connected together with the luminous intensity of the overall light and shadow, which is a linear change of the light source. As shown in the ninth, tenth, and eleventh figures: in this design, because the receiving component only hits one', the two straight light sources A and the straight light source B adopt the interleaved transmission and the interlaced synchronous reception (for example, The tenth figure shows the size of the reflected signal corresponding to the light shadow 3A and the light shadow 3B generated by the straight light source A and the straight light source b, and the reflected light of the light shadow 3A and the light shadow 3B will be treated. Measure the left and right movement of the line 5 and change it (as shown in the eleventh figure) because the brightness of the light intensity 4A and the light intensity 4β of the light and shadow are in the opposite direction of the money in the money area Z, so this The change in the magnitude of the difference between the received signals produced by the two light and shadows 3A and 3B can be used to detect the degree of color line offset. Because there are two rows of light-emitting element groups (LEDs) 10, 11 so that two sets of light can be staggered, when playing the bottom paper 2, the movement of the line 5 while waiting for the line 5 will be made; 1286597. The apparent difference in reflectivity on the 2 naturally affects the optical signal reflected back to the dual-purpose sensor 1. The reflected light passes back through the external permeable 16 to the single receiving unit 17, and the single receiving unit 17 receives the signal. Two sets of signals I and Π can be obtained by interleaving synchronous reception and signal processing, and the user can switch between switches to convert the analog circuit as needed, and process the two sets of received signals I and 为 into I-Π or I +Π. For the purpose of line detection or heel detection. Moreover, in the case of monitoring the edge line of the pole, the light source of the left and right sides of each row of the light-emitting elements can be turned off to avoid the edge of the substrate paper, and the straight line of the pole edge can also be detected. In addition, the present invention is a reaction that accurately captures the change in edge or line luminosity. The two rows of light-emitting elements may be yellow light in which all of the rows are blue and the other row is complementary to the color, so as to surely capture any color mark. In addition, the two rows of light sources can also be combined, for example, in white or LED lamps of the same color spectrum. This design has some advantages that the original design does not have. That is, the area where the sensor is to be corrected is the interval where the two beams are located. This area can be directly visualized, so the detectable area is very clear. 2. The two beams can be composed of light-emitting elements of complementary wavelengths, which can avoid the difficulty in detecting the difficulty in the conventional design because the line color is close to the spectrum of the light source. The above-described embodiments are merely illustrative of the principles of the invention and its efficiencies, and some of the embodiments thereof, are not intended to limit the invention. Modifications and variations of the above-described embodiments may be made by those skilled in the art without departing from the spirit and scope of the invention. Therefore, the scope of protection of the present invention should be as set forth in the appended claims. [FIG. Brief Description] The first figure is an embodiment of a conventional sensor.
