Description

Automatic book lending and selling machine

Technical Field

The invention relates to the field of book management equipment, in particular to an automatic book borrowing and selling machine.

Background

The research institute of Chinese news publishing publishes the fourteenth national reading survey, the average book reading quantity of the adult national people in 2016 of China is 7.86 books, and one item of data shows that up to 51.6% of the adult national people tend to read by taking a paper book, and the national people that tend to read by mobile phones only account for 33.8%. Paper books are still favored by half as many readers today where digital reading is already well developed. The paper reading is a reading mode which takes paper as a carrier and is different from electronic reading, has unique value and brings incomparable reading experience to people. With the development and progress of modern science and technology, especially the rapid development of information technologies such as the internet and the like, electronic reading also has some defects. For example, the electronic reading cost is relatively high, and is mainly embodied in a terminal of the electronic reading, and the electronic reading also requires flow or wifi (wireless fidelity) opening, and the like, and a certain cost is also generated. Moreover, sometimes the reading is inconvenient, the characters are small, the single-page display content is less, and the reading is not beneficial to middle-aged and elderly people when the reading is carried out on a tablet personal computer such as a mobile phone or an IPAd; when reading on electronic terminals such as mobile phones, computers and the like, it is not very convenient to annotate, add comments, perform comparison reading and the like; to the extent of reading and understanding, most people are used to mainly browse information, chat, friend making and game entertainment by using electronic terminals, and are not favorable for performing intensive reading by easily walking horse-looking flowers and precessing jujubes when reading by using the electronic terminals. Electronic reading has certain harm to human health, and people watching display screens of electronic terminals such as mobile phones and computers for a long time can cause certain damage to vision. Because the television and the ipod actively deliver the messages and the like, people passively accept the messages, and are difficult to or less form independent thinking, which is not beneficial to the brain and intelligence development of children; the books are passive when transmitting information and knowledge, and people carry out active thinking activities, so that the books are often read through independent processes of analysis, thinking, judgment, calculation, reasoning, memory and the like, and the books are read more, so that the brain and intelligence development of children is facilitated. However, the convenience of traditional paper reading is poor; firstly, the mode is single, and the propagation is slower, and a book will pass through processes such as printing, packing, transportation to the reader. Secondly, the purchase or borrowing of the books is inconvenient. At present, because the profit of book sale or lease is low, the book operating points are less and less, some towns may not have book operating points, and not have libraries of public interest, some counties have only one or two bookstores or one library of public interest, and many people are time-consuming and labor-consuming and inconvenient in book purchasing or borrowing. Traditional bookstores and libraries are convenient only for surrounding people, but are inconvenient for people with long distances, and some people may even need to run for a few kilometers to buy or borrow a book, and rural residents may even run for tens of kilometers. The country invests a great deal of financial resources, establishes numerous reading rooms in rural areas and is equipped with related books, and the purpose is to facilitate the reading of rural residents, increase the reading amount of the rural residents and improve the cultural knowledge level, information processing and technical ability of the rural residents. However, because the rural reading rooms have no professional or part-time managers, and the residents in the rural areas are dispersed, so that books are inconvenient to borrow, and many farmers go out in economic lag areas, the reading rooms are not opened for a long time, some reading rooms even become furnishings, are not opened basically, and do not play a due role.
