Abstract
A camera module includes an imaging unit including a holder holding a lens unit including a flange portion being at right angles to an optical axis, a front case to which the lens unit is fixed, and a rear case including a prop portion supporting the lens unit with the flange portion, the imaging unit being fixed by the flange portion put between the prop portion and the front case, the rear case including a buffer region configured to absorb a unit length of the imaging unit.
Claims9
A camera module comprising:
- an imaging unit including a lens unit including a flange portion being at right angles to an optical axis, a holder holding the lens unit, and a sensor substrate attached to the holder, a focus of the imaging unit being adjusted;
- a front case to which the lens unit is fixed;
- and
- a rear case including a prop portion supporting the lens unit with the flange portion, the imaging unit being fixed by the flange portion put between the prop portion and the front case, the rear case including a buffer region configured to absorb a unit length of the imaging unit.
A camera module comprising:
- an imaging unit including a holder holding a lens unit including a flange portion being at right angles to an optical axis;
- a front case to which the lens unit is fixed;
- and
- a rear case including a prop portion supporting the lens unit with the flange portion, the imaging unit being fixed by the flange portion put between the prop portion and the front case, the rear case including a buffer region configured to absorb a unit length of the imaging unit,
- wherein a plurality of the prop portions is arranged with the optical axis as a middle point or a center.
A camera module comprising:
- an imaging unit including an engaging concave portion in a lens holder holding a lens unit including a flange portion being at right angles to an optical axis;
- a first case portion including a flange arrangement portion arranging the flange portion;
- a second case portion including a prop portion supporting the flange portion, the prop portion engaging the engaging concave portion, the second case portion being joined to the first case portion;
- a fixing mechanism fixing the imaging unit to the first case portion in a direction of an optical axis of the lens unit by putting the flange portion between the flange arrangement portion and the prop portion;
- and
- an engaging mechanism making the second case portion to support the imaging unit by engaging the engaging concave portion and the prop portion in a direction that is at right angles to the optical axis.
A manufacturing method for a camera module, including:
- attaching, to a holder, a lens unit including a flange portion being at right angles to an optical axis of the lens unit and a sensor substrate to form an imaging unit including the lens unit, the holder and the sensor substrate;
- adjusting a focus of the lens unit;
- supporting, by a prop portion of a rear case, the lens unit of the imaging unit of which a focus is adjusted with the flange portion, and putting the flange portion between the prop portion and a front case to fix the lens unit, and arranging a back end portion of the imaging unit in a buffer region of which a height is set up by the prop portion;
- and
- connecting the front case and the rear case.
