Description
Technical field
The present invention relates to a kind of theft instrument, and in particular to the system for preventing books stolen.
Background technology
The antitheft instrument of books, which can be effectively prevented, to be lost book, conveniently simplifies management, be favorably improved operating efficiency, help
In the good office of creation and reading environment.With the continuous development of scientific technology, library's open stack management is helping reader certainly
Library, which is embodied, in terms of selection, raising books reading utilization rate, raising library works efficiency is complying with era development
One much progress of aspect, but at the same time, the drawbacks of produced by open-shelf service --- lose book, tear page, during this is also management work
More distinct issues.The own characteristic of open-shelf service how is taken into full account in terms of library configuration, the excellent of it is given full play to
More property, is that each librarians is worth spy while taking a variety of ancillary methods to reduce the inconvenience that open-shelf service is brought
The problem begged for.Under this problem, the antitheft instrument of books based on electromagnetic wave is obtained in practice as direct, effective anti-theft measure
The accreditation of vast library is unanimously arrived.
It is included following using step：
1. the antitheft special consumptive material-magnetic stripe of books is pasted onto in books crack, it is disguised fine；
2. installation books anti-theft antenna at passage or total gateway is borrowed in library；
3. normally handling the books for borrowing formality makes magnetic stripe failure by special Deperming Facility or is passed from anti-theft antenna side
Pass through, borrow completion；
4. when the books (books for paying magnetic stripe) of non-normal procedure are by outlet, the detection of books anti-theft antenna does not disappear
Magnetic chart book simultaneously sends audible and visible alarm, and reader, which makes up, borrows formality.
After readers' preference complete required books, reader is when borrowing the Taiwan Affairs Office's reason and borrowing formality, and librarian is doing
Reason passs away the books selected by reader from the side of burglary-resisting system after borrowing registration, and books are not through burglary-resisting system, reader
Burglary-resisting system is directly over after going through the formalities, then from for supporting the support frame of anti-theft antenna side that books are taken away.
The books burglary-resisting system that can commercially see at present, is roughly divided into the product of three kinds of different principles：That is electromagnetic wave
Principle harmony magnetic wave principle, less radio-frequency principle.The label of the product of different principle is not connected, is prevented using which type of
Theft system, required label is also just different but essentially identical using the equipment consumptive material (label) with principle.
In the practical application of the antitheft instrument of books, when someone steals support frame side of the books by support anti-theft antenna
When, alarm can be sent, but be due to borrow the passage gone out at passage or total gateway to have multiple, when there are many people while going out passage
When, manager can not accurately and timely be the discovery that the people of which passage has stolen books, causes subsequent treatment dependencies
Trouble is time-consuming.
The content of the invention
The stolen system of books is prevented present invention aims at offer, is solved due to borrowing what is gone out at passage or total gateway
Passage has multiple, and when having many people while when going out passage, manager can not accurately and timely be the discovery that the people of which passage steals
The problem of books.
The present invention is achieved through the following technical solutions：
The system for preventing books stolen, including books theft instrument body, the theft instrument body include support frame and control
Device, is provided with prompting component, the prompting component includes dynamic plate, electromagnet and torsion spring, described dynamic in the top surface of support frame as described above
