Phototypesetting machine is a new device developed in the 1970s. It uses the electronic computer to proofread the input text symbol, edit it, and then expose it to the photosensitive material through laser scanning technology to make the scanning beam brightness high. After focusing, The extremely thin beam has a scanning resolution of 40 lines/MM, so this photo-aligning machine can better reproduce the character glyph outline and stroke. This article will introduce you to the common faults of the imagesetter. The inspection was carried out in comparison with the row machine, but no obvious failure was found. Remove the upper cover of the cassette, open the photo-setting machine, and let the film enter the film manually. On the other hand, the hand-held motor of the photo-aligning machine automatically turns the wheel and finds that it is rotating, but the friction wheel of the collecting box The speed of rotation is slower. After shutting down, use your finger to move the wheel against the motorized wheel of the machine, and then add some resistance to the friction wheel of the box, and find that it does not rotate. After careful observation, we can guess that this reason is caused by the long-term friction caused by the rotating wheel of the take-up motor and the friction wheel of the take-up box, which causes the rubber to age and wear, resulting in poor contact between the two rubber wheels. Generally, it can be adjusted by comparing the film collection with the elastic scale of the steel shrapnel on the back of the motor to solve the fault, but we found that at this time, the elastic scale has been adjusted to the maximum extent. Therefore, it is only necessary to consider the shrinking wheel on the take-up motor and the take-up box to eliminate the malfunction. A set of recursive algorithms is designed to restore the compressed Chinese character information to a glyph at high speed, and it is suitable for hardware implementation, paving the way for the design of key laser photo-sequencing controllers in the future. What's more unique is that Wang Xuan came up with a high-tech trick to control the quality of the glyphs with large or small sensitive parts with parameter information, achieving high fidelity in glyph zooming and deformation. This invention alone is 10 years earlier than the West. In September 1975, Wang Xuan simulated the first flaw of the word "human" in the computer through software. This is a major breakthrough in Chinese character information processing technology. The 38-year-old Wang Xuan, with a glimpse of mathematics and wisdom, opened the door to the computer era.
