Description
Technical field
The invention belongs to office accommodation technical fields, more particularly, to a kind of safety paper shredder.
Background technique
With the arriving of era of knowledge-driven economy, more and more information are valuable or influence power, therefore much information must
It must be maintained secrecy.During handling information, need mostly to be applied to hard copy, that is, there are many important information to be note
It is loaded on paper, if if involving confidentiality or great stake, after the paper of information-recording is utilized, it is necessary to will
This paper is eliminated.
Modern society considers efficiency and environmental issue, will use broken when the paper of aforementioned carrying information is eliminated in processing
Paper machine rubs paper, to complete to eliminate the purpose of information on paper
Shredder is one of office and family's commonly used equipment.As shredder is using more more and more universal, people are to broken
The automation of paper machine and security performance require higher and higher, shredder on the market, although there is some improvement, most shredders
The degree of automation it is not high, to the person, there is also security risks for some.
Summary of the invention
The present invention for overcome the deficiencies in the prior art, provides a kind of highly-safe, efficient safety paper shredder.
To achieve the goals above, the invention adopts the following technical scheme: a kind of safety paper shredder, including shredded paper case, under
