Dynamic button type keyboard device

Abstract

Disclosed is a dynamic button type keyboard device, which comprises a circuit board, and at least two dynamic button components electrically connected to the circuit board. The dynamic button components are rotating bodies provided with a plurality of groups of button switches; and each group of button switches are electrically connected to the circuit board. Buttons in a keyboard input device are divided into a plurality of groups, each group of buttons are fixed on a rotating body, each rotating body is provided with a plurality of groups of button switches, the change of the groups of buttons is realized under the transmission of a motor, a plurality of rotating bodies can change positions once before button input each time, and a button arrangement sequence when the information input is carried out each time is different, so that the dynamic change of the button switches is realized, and keyboard input information can be effectively prevented from being stolen by others. Because the divided plurality of groups of buttons is rotatable, others can be prevented from installing a stealing keyboard on a keyboard in a re-cover mode. The present invention can be widely applied to input devices such as bank teller machines, point-of-sale (POS) machines, and public telephones.

Description

Technical field [0001] The present invention relates to a keyboard input device, and more specifically to a keyboard device composed of dynamically changing buttons. Background technique [0002] At present, keyboard input devices are used in electronic equipment such as bank teller machines, POS machines, and important computer rooms and archive warehouses. Key military sites, research institutes, and cultural relics exhibitions and other important areas also require password input. These keyboard input devices are usually Important information of individual users will be involved, such as account information, account passwords, etc. Since most of the traditional keyboard input devices adopt a fixed button structure, these devices in public places are often peeped by criminals using remote monitoring and other methods, which leads to the theft of important personal information. Even if the finger is occluded during input, criminals will still perform a more detailed analysis of...
