ABSTRACT:
A signal generating module for an electronic apparatus is provided. The signal generating module includes a processor, a roller, a resistant film, a conducting member, a first lead and a second lead. The roller has a rotary center and is rotably connected to the electronic apparatus thereby. The conducting member is connected to the rotary center to rotate together with the roller. The conducting member has an end including a conducting contact point. The conducting contact point is configured to rotate around the rotary center along a motion path accompanying the rotation of the roller, wherein the motion path is disposed at a first area of the resistant film. The first lead is coupled to the processor and in contact with the resistant film. The second lead is coupled to the processor, and coupled to the conducting member via the rotary center.
