<p>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.</p> |
