Driving module, restoration method and imaging device

A restoration method, suitable for a driving module comprising a circuit board, a rotating member, and a power source, wherein the circuit board has a control circuit, a first conductive portion, and a plurality of second conductive portions separated from the first conductive portion respectively, the first conductive portion and the second conductive portions are respectively electrically connected to the control circuit, a rotating member is rotatably disposed on the circuit board and has a first abutment and a second abutment electrically conductive to each other, the power source is mechanically linked to the rotating member and electrically connected to the control circuit, the first abutment constantly abuts against the first conductive portion, and the second conductive portions are located on a rotating path of the second abutment, the restoration method comprising:

• activating the driving module, wherein the second conductive portions are assigned same electric potentials, the electric potential of the second conductive portion is changed when the second conductive portion is electrically conductive to the first conductive portion through the second abutment and the first abutment, and the electric potential of the second conductive portion is not changed when the second conductive portion is not electrically conductive to the first conductive portion;
• and
• the control circuit determines the electric potentials of the second conductive portions,
• wherein when the electric potentials of the second conductive portions are the same, the control circuit rotates the rotating member relative to the circuit board through the power source until the second abutment travels to one of the second conductive portions to change the electric potential of the one of the second conductive portions, and
• when the electric potential of one of the second conductive portions is changed, the control circuit determines a location of the one of the second conductive portions on the circuit board to determine whether to drive the rotating member and a rotating process of the rotating member.

An imaging device, comprising:

• a driving module, comprising:
• a circuit board, having a control circuit, a first conductive portion, and a plurality of second conductive portions separated from the first conductive portion respectively, wherein the first conductive portion and the second conductive portions are respectively electrically connected to the control circuit;
• a rotating member, rotatably disposed on the circuit board and having a first abutment and a second abutment electrically conductive to each other;
• and
• a power source, mechanically linked to the rotating member, electrically connected to the control circuit, and controlled by the control circuit to rotate the rotating member relative to the circuit board, wherein the first abutment constantly abuts against the first conductive portion, and the second conductive portions are located on a rotating path of the second abutment;
• and
• an imaging module, disposed on the rotating member and electrically connected to the control circuit, wherein after the imaging device is activated, the control circuit drives the rotating member to restore the imaging module according to electric states of the second conductive portions.
