    The present invention has been made in view of the circumstances of the above-described prior art, and an object of the present invention is to shift the position when fixing the image pickup element with respect to the optical axis after adjusting the position while simplifying the structure. It is difficult to provide an imaging apparatus that can improve functional reliability without reducing impact resistance against impact force such as dropping.

    A first imaging device of the present invention includes an imaging lens having an optical axis, a lens holding member that holds the imaging lens, an imaging element that captures a subject image formed through the imaging lens, and a fixed that fixes the imaging element. An image pickup device that includes a plate and is fixed to the lens holding member via an adhesive in a non-contact state with the lens holding member, and is disposed in a non-contact manner with the fixing plate to restrict the fixing plate from falling off. And a connecting member connected to the lens holding member, and an adhesive interposed between the connecting member and the fixing plate.

    According to this configuration, after the optical axis position adjustment (alignment in the optical axis direction, alignment in the direction perpendicular to the optical axis, tilt alignment with respect to the optical axis, etc.) of the imaging element with respect to the imaging lens (its optical axis), imaging is performed. The lens holding member holding the lens and the fixing plate fixing the imaging element are fixed by an adhesive interposed between them, and the connecting member (having a restricting portion) connected to the lens holding member and the fixing plate Since it is fixed by the adhesive interposed between the two, it is possible to prevent positional adjustment deviation, and even if the adhesive between the lens holding member and the fixing plate is peeled off by an external impact force or the like, the connecting member The restriction plate (and the adhesive interposed between the connecting member and the fixing plate) can prevent the fixing plate (and the image sensor) from falling off.

    According to this, while achieving simplification of the structure and the like, it is difficult for the image sensor to be displaced after the position adjustment of the image sensor with respect to the optical axis, and adhesive fixing is possible not only at the outer edge of the fixing plate but also near the center of the fixing plate. As a result, an imaging device that has high impact resistance against impact force such as dropping, can prevent parts (fixing plates, imaging elements, etc.) from falling off, and can improve functional reliability can be obtained.

    In the configuration according to the first imaging device, the connecting member is a screw with a head having a screwed shaft portion and a head having a diameter larger than that of the shaft portion, and the lens holding member is a screw with a head. The fixing plate has a through hole that allows only the shaft of the head screw to be inserted in a non-contact manner. The head screw is screwed into the screw hole of the lens holding member. It is possible to adopt a configuration in which the fixing plate is fixed to the fixing plate via an adhesive in a state where the fixing plate is not in contact with the fixing plate.

    According to this configuration, the fixing plate on which the imaging element is fixed is opposed to and held on the back side of the lens holding member that holds the imaging lens with a predetermined gap (in a non-contact state). The shaft part of the lens is passed through the through-hole from the back of the fixing plate and screwed into the screw hole of the lens holding member to hold it in a non-contact state with the fixing plate. (This adhesive may be pre-applied to the back side of the lens holding member or the outer edge of the fixing plate), and the adhesive is injected between the screw with the head and the fixing plate. Then, after the optical axis position is adjusted, the adhesive is solidified (for example, by ultraviolet irradiation), so that it is possible to prevent the positional deviation after the optical axis adjustment and to obtain an imaging device with high impact resistance.

    A second imaging device of the present invention includes an imaging lens having an optical axis, a lens holding member that holds the imaging lens, an imaging element that captures a subject image formed through the imaging lens, and a fixed that fixes the imaging element. An image pickup device that includes a plate and is fixed to the lens holding member via an adhesive in a non-contact state with the lens holding member, and is disposed in a non-contact manner with the fixing plate to restrict the fixing plate from falling off. And a connecting projection formed integrally with the lens holding member, and an adhesive interposed between the connecting projection and the fixing plate.

    According to this configuration, after the optical axis position adjustment (alignment in the optical axis direction, alignment in the direction perpendicular to the optical axis, tilt alignment with respect to the optical axis, etc.) of the imaging element with respect to the imaging lens (its optical axis), imaging is performed. The lens holding member that holds the lens and the fixing plate that fixes the imaging element are fixed by an adhesive interposed therebetween, and the connecting projection and the fixing plate that are integrally formed with the lens holding member (having a regulating portion) Is fixed by an adhesive interposed between them, so that the positional adjustment can be prevented from being displaced, and even if the adhesive between the lens holding member and the fixing plate is peeled off by an external impact force or the like, The fixing plate (and the image sensor) can be prevented from falling off by the restricting portion of the connecting protrusion (and the adhesive interposed between the connecting protrusion and the fixing plate).

    According to this, while achieving simplification of the structure and the like, it is difficult to be displaced when fixing the image sensor with respect to the optical axis after the position adjustment, and functionally without reducing impact resistance against impact force such as dropping. An imaging device capable of improving reliability can be obtained.

    In the configuration according to the second imaging device, the fixing plate has a through hole that allows the connecting projection to be inserted in a non-contact manner, and the connecting projection forms a regulating portion after being inserted into the through hole of the fixing plate. The structure which has the front-end | tip part deform | transformed as much as possible, and is firmly fixed to the fixing plate via the adhesive in a state where the front-end portion is deformed and is not in contact with the fixing plate can be employed.

    According to this configuration, on the back side of the lens holding member that holds the image pickup lens, the fixed plate that fixes the image pickup device is opposed to and held with a predetermined gap (in a non-contact state), and the connection protrusion Is passed through the through hole of the fixing plate and held in a non-contact state with the fixing plate, and the tip of the connecting projection is crushed (deformed) into a bowl shape, and the lens holding member (on the back side) and the fixing plate (outer edge of the fixing plate) (This adhesive may be pre-applied to the back side of the lens holding member or the outer edge of the fixing plate), and the adhesive is injected between the connecting projection and the fixing plate. By adjusting the optical axis position and then solidifying the adhesive (for example, by ultraviolet irradiation), it is possible to prevent the positional deviation after the optical axis adjustment and obtain an imaging device with high impact resistance.

    According to the imaging apparatus having the above-described configuration, it is difficult to shift the position of the imaging element after fixing the position relative to the optical axis while reducing the impact resistance against an impact force such as dropping while achieving simplification of the structure. Thus, an imaging device capable of improving functional reliability can be obtained.
