ABSTRACT:
A page-turning means with adjustable speed comprises a retaining stage, a base plate having switch function, a spring means for providing rebounding force and a semi-circular wheel. The base plate has electronic circuit, connection terminal, and a plurality of elastic plates functioning as switch, and can accommodate the T-shaped spring means. The voltage level change resulting from the on-off state of the switches being sent to external controller through the terminals. The bottom end of the semi-circular wheel is connected to the base plate. The bottom of the semi-circular wheel is in contact to top end of the spring means. When the the semi-circular wheel is rotated by external force, one end portion of the spring means is suppressed to tough one or two elastic plate(s) and voltage of various levels is generated. A controller can output signal to control the page turning speed according to the generated voltage level.
