Embodiment 1

[0049] A mobile memory data clearing device 100, such as figure 1 , figure 2 with image 3 As shown, a processor 300 for controlling data removal of the mobile memory 200 and a port 600 for connecting with the mobile memory 200 are provided.

[0050] Processor 300 comprises: a data input and output interface 310, is connected with port 600, and the kind of port 600 is a lot, at least comprises one or two in USB interface, SD card interface, MD card interface, MS card interface or TF card interface above.

[0051] In a preferred embodiment, the port 600 can also have at least one USB socket and at least one memory card insertion slot, wherein one memory card insertion slot can insert at least one type of memory card, and has such functions The storage card insertion slot of the memory card is shown in the Chinese patents whose patent announcement numbers are CN2582200, CN2737011, CN2705995 or CN201340601.

[0052] A microprocessor 320 is used to control the operation of th...

Embodiment 2

[0071] A mobile memory data clearing device 100, such as Image 6 , Figure 7 As shown, the other structures are the same as those in Embodiment 1, except that the processor 300 is of a different model, and an expansion circuit 400 is provided corresponding to the device 100 for erasing mobile memory data. The input end of the expansion circuit 400 is connected to the data input and output interface 310 of the processor 300 , and the output end of the expansion circuit 400 is connected to the port 600 .

[0072]Because in the prior art, the data input and output interface 310 of the processor as part of the processor 300 cannot be directly connected to the port, so the expansion circuit 400 needs to be set, and one end of the expansion circuit 400 is connected to the data input and output interface of the processor 300. 310 connection, the other end of the expansion circuit 400 can be directly connected to the port 600.

[0073] The model of this type of processor 300 is 305...

Embodiment 3

[0079] A kind of paper shredder with mobile storage data clearing device 100, such as Figure 8 As shown, the mobile memory data clearing device 100 as described in Embodiment 1 is provided.

[0080] Since the shredder itself is provided with a processor, the processor 300 of the mobile storage device 100 can be configured to share the same chip as the processor of the shredder, so as to save costs.

[0081] Taking the processor model CY768013 as an example, the shredder is equipped with OVERLORD overload terminal, OVERHEAT overheating terminal, MOTORRELAY1 motor relay terminal 1, MOTORRELAY2 motor relay terminal 2, OVERLOAD LED overload indicator terminal, OVERHEATLED overheating indicator terminal, POWERLED power indicator Light terminal, FWD LED forward rotation indicator terminal, REVLED reverse indicator terminal, FULLIN full paper sensor terminal and IRIN paper feed sensor terminal, the pin 18 of the processor is connected to the OVERLORD overload terminal, and the pin ...

Abstract

The invention provides a data clearing apparatus for a mobile memory, and office equipment and a shredder with the data clearing apparatus. The data clearing apparatus is provided with a processor and a port, wherein the processor comprises an input-output interface, a microprocessor, a control circuit, a data memory and a program memory. The microprocessor is provided with a storage device detection module, an information clearing module, a determination module for completion of clearing, a clearing frequency determination module, a clearing grade mode selection module and a clearing confirmation module. The control circuit acquires the information of the input-output interface and conveys the information to the microprocessor; the microprocessor outputs processed information to the control circuit; and then the control circuit outputs control information to the input-output interface to clear data in a mobile memory based on the processed information. The data clearing apparatus for a mobile memory and the office equipment and the shredder with the data clearing apparatus are easy to operate and can clear data in a mobile memory as required.

Description

technical field [0001] The invention relates to a technology for clearing electronic data, in particular to a data clearing device for a mobile memory, office equipment with the device, especially a paper shredder with the device. Background technique [0002] With the development of society, there are more and more forms of electronic storage devices, the size is smaller and smaller, and it is more and more convenient to carry. In order to prevent data leakage in the mobile storage, it is usually chosen to delete the data in the mobile storage or format the mobile storage. clearing effect. [0003] Chinese patent ZL03158951.0 Data clearing method of memory and related devices provide a method for clearing data in memory, using a computer system, the computer system includes a processor and a memory control circuit. The clearing method includes sending a predetermined logic value generated by the processor to the memory control circuit, and the memory control circuit repea...
