The invention discloses a non-contact button input device, which is characterized by comprising a button for detecting physical input of a user; and a non-contact button unit that automatically registers an input of the button under a predetermined condition when sensing that an object approaches a sensing area formed in front of the button, the non-contact button unit including: a proximity sensor that forms a sensing area from a surface of the button to a position separated by a first sensing distance; and a long-distance sensor which forms a sensing area from the surface of the button to a position of a second sensing distance farther than the first sensing distance, and determines the proximity validity of the object by comprehensively considering whether the long-distance sensor senses the object and whether the short-distance sensor senses the object. And determines whether or not the button is registered by the non-contact button unit.
本发明公开了一种非接触式按钮输入装置,其特征在于,包括:按钮,检测用户的物理输入;以及非接触按钮部,当感知到物体向形成在按钮的前方的传感区域接近时,在预定条件下自动登记按钮的输入,上述非接触按钮部包括:近距离传感器,从按钮的表面到相隔第一传感距离的位置形成传感区域;以及远距离传感器,从按钮的表面到相隔比第一传感距离更远的第二传感距离的位置形成传感区域,通过综合考虑远距离传感器是否感知到物体以及近距离传感器是否感知到物体,来判断物体的接近的有效性,并确定是否通过非接触按钮部登记上述按钮。
