Camera module with imaging unit and light emitter
A circuit board includes a first rigid printed wiring board mounted with an imaging unit, a second rigid printed wiring board mounted with an LED, and a foldable first flexible printed wiring board coupling the first rigid printed wiring board and the second rigid printed wiring board. A shield case is further included for holding the second rigid printed wiring board in a state in which the first flexible printed wiring board is folded an even number of times, a first main face of the second rigid printed wiring board and a first main face of the first rigid printed wiring board face in an identical direction, and the second rigid printed wiring board lies at a separated position from the first main face of the first rigid printed wiring board.
1. A camera module comprising:
an imaging sensor configured to capture an image of an object;
a light emitter configured to illuminate the object with illumination light; and
a circuit board including:
a first rigid printed wiring board mounted with the imaging sensor;
a second rigid printed wiring board mounted with the light emitter; and
a foldable flexible printed wiring board connecting the first rigid printed wiring board and the second rigid printed wiring board;
wherein,
the first rigid printed wiring board has a holder which is configured to hold the second rigid printed wiring board in a state in which (i) the flexible printed wiring board is folded an even number of times and (ii) the light emitter and the imaging sensor face the same direction,
the holder is arranged at a position which is different from the imaging sensor, and
the holder holds the second rigid printed wiring board at a height higher than a surface of the first rigid printed wiring board.
2. The camera module according to claim 1 , wherein
the holder is disposed on the first main face of the first rigid printed wiring board, and is formed in a case shape at least having an opening on a side facing the first main face, and
a predetermined electronic component is disposed in a space in the holder.
3. The camera module according to claim 2 , wherein the holder is a shield member configured to shield electromagnetic noise emitted from the predetermined electronic component.
4. The camera module according to claim 1 , wherein the circuit board is a rigid flexible printed wiring board in which the first rigid printed wiring board, the second rigid printed wiring board, and the flexible printed wiring board are integrated together.
5. A camera module comprising:
