Abstract:
1. A signal generating module, for an electronic apparatus, comprising: a processor, connected to the electronic apparatus; a roller, having a rotary center and being rotably connected to the electronic apparatus; a resistance film, connected to the electronic apparatus; a conducting member, connected to the rotary center to rotate together with the rotary center, wherein an end of the conducting member comprises a conducting contact point to rotate around the rotary center along a motion path accompanying the rotation of the roller, and wherein the motion path is located at a first area of the resistant film; a first lead, connected to the electronic apparatus, coupled to the processor, and being in contact with the resistant film; and a second lead, connected to the electronic apparatus, coupled to the processor, and coupled to the conducting member via the rotary center, wherein when the roller is driven to rotate by an external force, the conducting contact point is driven to move on a surface of the resistant film, and the movement of the conducting contact point changes a resistance between the first lead and the conducting contact point, and therefore the processor generates a first signal by evaluating signals transmitted from the first lead and the second lead according to the change of the resistance.
