  • the range in which the end portion of the shield plate 6 spreads can be narrowed, and the second substrate 52 can be configured so as not to easily come off the shield plate 6.
  • the end of the shield plate 6 may be configured to overlap with the rear case 7. Even in this case, similarly to the above, the configuration can be made in which the second substrate 52 is prevented from dropping out of the shield plate 6.
  • the rear end of the bent portions 64a and 64b which are the end portions in the opening direction of the shield plate 6, is positioned so as to overlap the front case 3 in a plane perpendicular to the optical axis direction. It has a shape projecting from the side toward the front side. As a result, when the bent portions 64a and 64b extend outward, the end portion is easily in contact with the front case 3, so that the second substrate 52 can be reliably prevented from falling off.
  • Embodiment 3 a third embodiment of the present invention will be described with reference to FIG.
  • the imaging device of the present embodiment differs from the imaging device of the second embodiment in the shapes of the protrusions 521 a and 521 b of the second substrate 52.
  • the description of the same configuration as in the first embodiment and the second embodiment will be omitted, and only the characteristic parts different from the first embodiment and the second embodiment will be described.
  • FIG. 13 is a cross-sectional view of the imaging device at a position CC in FIG.
  • the protrusions 521 a and 521 b of the second substrate 52 of the present embodiment protrude at an obtuse angle with respect to the edge of the second substrate 52.
  • the end portions of the protrusions 521 a and 521 b on the front side in the optical axis direction and in contact with the fitting portions 61 a and 61 b have an inclination. That is, the notch-shaped portion formed by the edge of the second substrate 52 and the protrusions 521a and 521b has an acute angle.
  • the protrusions 521 a and 521 b of the second substrate 52 preferably protrude with an angle of 95 degrees or more with respect to the edge of the second substrate 52.
  • the protrusions 521a and 521b are preferably formed to have an angle of 5 degrees or more with respect to a plane perpendicular to the optical axis.
  • the protrusions 521 a and 521 b of the second substrate 52 are configured to protrude at an angle of 105 degrees or more with respect to the edge of the second substrate 52. According to this configuration, a certain amount of stress or more can be more easily generated between the shield plate 6 and the second substrate 52, so that the second substrate 52 can be further removed from the shield plate 6. It can be effectively suppressed.
  • the plate spring portions 62 and 63 in the above embodiments are configured to apply biasing forces in directions perpendicular to each other with respect to the second substrate 52, the configurations are not necessarily configured to apply biasing forces in directions perpendicular to each other. It is also possible to obtain a certain effect even when the biasing force is applied from different directions.
  • the configuration including the two rigid substrates of the first substrate 51 and the second substrate 52 has been described, but a configuration including an additional rigid substrate may be adopted.
  • the imaging device can be further miniaturized by arranging the additional substrate at a predetermined angle (for example, perpendicular) with respect to the first substrate 51 similarly to the second substrate 52. Even if the additional substrate is arranged horizontally to the first substrate 51, a certain effect can be obtained.
  • the present invention is suitably used as an on-vehicle imaging device or the like.

Abstract

Ce dispositif d'imagerie comprend : une unité d'imagerie qui capture des images d'un sujet ; un premier substrat sur lequel est montée l'unité d'imagerie ; un second substrat sur lequel est monté un composant électronique qui est électriquement connecté au premier substrat ; et un barillet de lentille qui maintient une lentille. Le dispositif d'imagerie a une configuration dans laquelle le second substrat est disposé à un angle prescrit par rapport au premier substrat. En conséquence, un dispositif d'imagerie relativement petit peut être configuré avec une longueur raccourcie dans la direction de l'axe optique par rapport à une configuration dans laquelle le premier substrat et le second substrat sont disposés horizontalement le long de l'axe optique.
