[Embodiment] Hereinafter, the following preferred embodiments will be described in detail with reference to the accompanying drawings. 1 to 4 illustrate an input device 100 according to an embodiment of the present invention, which includes a substrate 10 and a turntable 12. The substrate 10 is made of an insulating material and has a first surface 〇101, a second surface 102 opposite to the first surface 101, and a circular passage extending through the first surface 101 and the second surface 102. Hole 103. The first surface 101 is provided with a ring-shaped resistive layer 104 surrounding the through hole 103 and having an opening, and a ring-shaped wire 105 which is concentric with the resistive layer 104 and has an opening. The resistance layer 104 and the wire 105 are not electrically connected. In the present embodiment, the wire 105 is located outside the ring of the resistance layer 104. The resistor layer 104 is connected to a first solder joint 106 and a second solder joint 107 at two ends of the opening, and one end of the wire 105 is connected to a third solder bump 108. A constant predetermined voltage is provided between the first solder joint 106 and the second solder joint 107, and an external circuit (not shown) is connected between the second solder joint 107 and the third solder joint 108. The voltage or resistance between the second pad 107 and the third pad 108 is measured. In the embodiment, the substrate 10 is further provided with at least one buckle 109 for clamping the substrate 10 on an electronic device. The turntable 12 is rotatably disposed on the substrate 10. The turntable 12 has a circular base 121 and a shaft 122 of a circular 6 201039187 concentrically disposed on the base 121. The radius of the base 121 is larger than the diameter of the through hole 103 of the substrate 10. The radius of the shaft 122 is slightly smaller than the diameter of the through hole 103. A step surface 123 surrounding the shaft body 122 is formed on the base body 121. The step surface 123 is provided with a conductive block 124. The length of the conductive block 124 is slightly larger than the interval between the resistive layer 104 and the wire 105, and the width is much smaller than the circumference of the resistive layer 104 and the wire 105. The base 121 is disposed on the first surface 101 of the substrate 10, and the shaft 122 passes through the through hole 103 and slightly protrudes from the second surface 102. The stepped surface 123 covers the resistive layer 104 and the wire 105 on the first surface 101.

A power source 22 is connected between the first solder joint 106 and the second solder joint 107, and a detecting circuit 221 is connected between the second solder joint 107 and the third solder joint 1〇8. The detecting circuit is connected. 221 is used to measure the voltage or resistance between the second solder joint ι7 and the third solder joint. A controller 222 is connected to the detecting circuit 221 for determining the rotation direction or position of the conductive block 124 according to the output signal of the detecting circuit 221, and controlling the electronic device according to the rotating direction or position. The cursor moves on the display screen (not shown). In the present embodiment, when detecting that the conductive block 124 is rotated in the opposite direction of the d direction, the controller 222 controls the cursor to move upward, and when the 8 201039187 conductive block 124 is along the d direction辕-蛀日, w ^ ^ rotation ^ ' then controls the cursor to move downward, and the conductive block 124 is on the display position of the relative position cursor on the display screen on the electric jj and the display resistance layer 104 - correspond.
