Microfilm technology under network environment
Promote the use of micro products. . Microfilm technology in China from the overall utilization of the library situation, the status quo is unsatisfactory, one of the important reasons is that publicity is not enough. Most readers know the library is the only temple of knowledge, is the use of an important place for acquiring knowledge from books. While little or no idea microfilm technology,[link widoczny dla zalogowanych], and even some people with the landscape \Just think, what is the microfilm reader to the technology are not clear,[link widoczny dla zalogowanych], how can we make full use of microforms for it? Therefore, technology should be widely publicized on the microfilm is to improve the utilization of microform important ways, and network technology to the Arab-Israeli propaganda and l 『using microfilm technology to provide vast space. As the second largest after the TV media,[link widoczny dla zalogowanych], the Internet giant's advocacy role is obvious to all digitized information is available through a dedicated microfilm A page posted on the Internet, readers can be anywhere in the world through the network to understand the exchange of experience microform】 7 Technology 2 / 2002 Minolta RP509 note card reader-printer output is not in place in Japan Troubleshooting Minolta copiers manufactured RP509 reading for 35ram roll film and the window card copy restore, restore the most wide-format machine uses static electricity for the A2 Copy method, with automatic and manual exposure control, positive and negative, like copying, reliable performance, reduction of high quality. Harbin Electric Machinery Co., Ltd. Since 1993, people RP509 reader-printer has been purchased, the machine has been charged with the companies work to restore all the microfilm operation of long-term frequent use, a number of aging or to transmission components have been broken, can not make the card through the window into the transfer orbit accurate location of people working, causing frequent machine failures, does not work. We judge, RP509 reader-printer is mainly due to the above automatic transmission failure window part of the multi-axis card and the connection between the transmission shaft has serious aging circular apron, slip occurs during the friction drive, so the card can not open the window transported to the operating position. Difficult due to the current domestic market can buy the same specifications as the circular apron, rubber sleeve first, we tried to replace the aging of the circular rubber ring test has been found that the elastic rubber sleeve and the tension and round King Ring wave not the same, resulting in delivery of the travel card window is not accurate, not in place, the transmission type screen from the point of view can only read part of the contents of the card window, you can not restore the integrity of the entire contents on microfilm. Thus, we more than rubber goods store in Harbin and the original Ring to find similar alternatives. Purchased from the select alternatives to the original apron close to the same diameter size to trial, the results of several experiments card or automatic transmission can not accurately place windows, can not achieve satisfactory requirements. # Remove the automatic transmission window again, then move some pieces, one by a careful analysis of the circular rubber ring and carefully determine the reasons for this failure, the results found in a shaft on the other end of a groove,[link widoczny dla zalogowanych], which corresponds to one roots also have grooves on the short axis, but they have no connections between the cast. Here we analyze the circular rubber ring should be connected to the drive between the two axes to achieve our two axes according to the distance between the circle from the apron to buy select the appropriate alternative to the round of film has lost Aprons , automatic transmission window part of this card to work to restore the knowledge of information technology-related microfilm, and according to their need to browse, use the microform digital content. It can be said to Micrographics A network libraries from relatively small to the world, but also to a broader utilization. (4) implementation of the Interlibrary Resource Sharing asked. Protection of Ancient Books to rescue its historical role to play, so as to construction and development of services in modern society the use of microfilm technology libraries rescue work protecting ancient books has been completed, but due to historical, geographical, cultural and other factors, the Museum The microform collection is different. This brings the reader's access problems, and if readers want to access certain documents and microforms, then there is no local library, but go to the field to the other museum, it is neither economical and time-consuming. Network application is asked to carry out interlibrary loan to libraries and data exchange】 8 provides the most convenient way. The Museum of the agreement according to exchange data microform collections and readers across the country a huge number of microform information, the reader simply to any one of them can access to the national library of the Museum's collections. This will not only provide the reader with a fast and convenient times A network information service, and greater collaboration between the Library,[link widoczny dla zalogowanych], effective use of collections, resource sharing is important, above, in the first network environment. Microfilm technology not only will not be replaced by other technologies, but rather with the development of modern science and technology continue to improve, so the library in the future play an important role.
